Can be provided.

以下、本発明の絞り加工用プレス金型装置の実施形態を図面に基づき説明する。図１はプレス金型装置１の正面図であり、このプレス金型装置１は上下動可能なスライド２と、このスライド２下面に固定される上金型３と、ベッド４と、このベッド４上に固定されるボルスタ５と、このボルスタ５上面に固定される下金型６と、下金型６の周りに上下動可能に配されて初期位置に配置すべく前記上金型３に向かって弾性装置１０によって押圧されているブランクホルダ７と、コラム８と、クラウン９と等を備えている。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a press working die device for drawing according to the present invention will be described based on the drawings. FIG. 1 is a front view of a press mold apparatus 1. This press mold apparatus 1 includes a slide 2 that can move up and down, an upper mold 3 that is fixed to the lower surface of the slide 2, a bed 4, and the bed 4. A bolster 5 fixed on the upper side, a lower mold 6 fixed on the upper surface of the bolster 5, and arranged around the lower mold 6 so as to be movable up and down, toward the upper mold 3 to be placed at an initial position. A blank holder 7, which is pressed by the elastic device 10, a column 8, a crown 9, and the like are provided.

図２に示すように、前記ブランクホルダ７の内周面と下金型６の外周面にはそれぞれ所定間隔を存して低摩擦材から成る案内部材７Ａ、６Ｄが形成され、下金型６の外周に沿ってブランクホルダ７が円滑に上下動できるように案内される。また、前記弾性装置１０はベッド４内に内蔵された弾性動力源のエアシリンダー（図示せず）と、このエアシリンダーのロッド上部が固定されたクッション板（図示せず）と、クッションピン１１とから構成される。このクッションピン１１は前記クッション板と前記ブランクホルダ７との間に抜き差し可能に設けられて、下金型６の下部に外方に延在した鍔６Ｅ及びボルスタ５を貫通して前記ブランクホルダ７を押し上げている。 As shown in FIG. 2, guide members 7A and 6D made of a low-friction material are formed on the inner peripheral surface of the blank holder 7 and the outer peripheral surface of the lower mold 6 with a predetermined distance between them. The blank holder 7 is guided so that it can move up and down smoothly along the outer periphery. The elastic device 10 includes an air cylinder (not shown) of an elastic power source built in the bed 4, a cushion plate (not shown) to which an upper portion of the rod of the air cylinder is fixed, a cushion pin 11, Consists of The cushion pin 11 is detachably provided between the cushion plate and the blank holder 7, and penetrates the flange 6 </ b> E and the bolster 5 that extend outward to the lower part of the lower mold 6, and the blank holder 7. Is pushed up.

そして、図２に示すように、上金型３が上方に位置されている際には、ブランクホルダ７は弾性装置１０に支持されて上方に位置している。この状態で、ボルスタ５の上面に取り付けた下金型６の上に概ね平板状の被加工材料１５を載置してセットし、図示しない駆動源によるスライド２及び上金型３が下降することによって前記被加工材料１５に当接すると、ブランクホルダ７もまた上金型３の下降と共に前記下金型６の案内部材６Ｄに沿って前記ブランクホルダ７の案内部材７Ａが案内されながら弾性装置１０の弾性力に抗して下降し始める（図３及び図４参照）。 As shown in FIG. 2, when the upper mold 3 is positioned upward, the blank holder 7 is supported by the elastic device 10 and positioned upward. In this state, the substantially flat work material 15 is placed and set on the lower mold 6 attached to the upper surface of the bolster 5, and the slide 2 and the upper mold 3 are lowered by a drive source (not shown). When the upper holder 3 is lowered, the blank holder 7 is also guided along the guide member 6D of the lower mold 6 while the guide member 7A of the blank holder 7 is guided. It begins to descend against the elastic force (see FIGS. 3 and 4).

更に、上金型３が下降してブランクホルダ７に圧力を加えて下金型の上面がブランクホルダ７の上面より突出し、上金型３の下面と下金型６の上面とが十分に接近すると、下金型６の上面及び上金型３の下面（両金型の製品形状面）に倣った所定形状の製品をプレス加工することとなる（図５参照）。 Further, the upper die 3 is lowered and pressure is applied to the blank holder 7 so that the upper surface of the lower die protrudes from the upper surface of the blank holder 7, and the lower surface of the upper die 3 and the upper surface of the lower die 6 are sufficiently close to each other. Then, a product having a predetermined shape following the upper surface of the lower mold 6 and the lower surface of the upper mold 3 (product shape surfaces of both molds) is pressed (see FIG. 5).

そして、この下降後、上金型３は上昇し、上金型３及びブランクホルダ７は逆の動作をして、それぞれ初期位置に戻され、この加工された前記被加工材料（製品）１５は手動又は自動で取出され、新たな加工すべき被加工材料１５が下金型６の上に載置されてセットされて、前述したような動作が繰り返される。 After the lowering, the upper mold 3 is raised, the upper mold 3 and the blank holder 7 are reversely moved to their initial positions, and the processed material (product) 15 processed is The workpiece 15 to be processed is taken out manually or automatically, placed on the lower mold 6 and set, and the above-described operation is repeated.

なお、図６に示すように、前記ボルスタ５上面には大きさ等の異なる種々の下金型６を取り付け可能とするために、所定間隔を存して平行な複数列の逆Ｔ字形状の取付溝２０が開設され、また前記クッションピン１１が貫通する孔が複数開設されている。そして、図７に示すように、下金型６の前部及び後部にはＵ字形状の取付溝２２が開設された取付片２１がそれぞれ外方へ例えば２つずつ突設されている。そして、前記取付溝２０の幅広部２０Ａ内にその頭部（幅狭部２０Ｂの長さより大きな直径である）が挿入されると共にその軸部が幅狭部２０Ｂより上方へ突出したボルト２３を取付溝２２を介して取付片２１を貫通させた状態にして、ワッシャー２４を介して上方からナット２５を締め付けることにより前記ボルスタ５に下金型６を取り付けることができる。 As shown in FIG. 6, in order to allow attachment of various lower molds 6 having different sizes and the like on the upper surface of the bolster 5, parallel rows of inverted T-shaped parallel lines are provided at a predetermined interval. A mounting groove 20 is opened, and a plurality of holes through which the cushion pin 11 passes are opened. Then, as shown in FIG. 7, for example, two mounting pieces 21 each having U-shaped mounting grooves 22 project outwardly from the front portion and the rear portion of the lower mold 6. Then, the head 23 (having a diameter larger than the length of the narrow portion 20B) is inserted into the wide portion 20A of the mounting groove 20, and the bolt 23 whose shaft portion protrudes upward from the narrow portion 20B is attached. The lower die 6 can be attached to the bolster 5 by tightening the nut 25 from above through the washer 24 with the attachment piece 21 being passed through the groove 22.

そして、図示しないが、スライド２に上金型３を同様な構造によって取り付けることができる。しかしながら、このような取り付け構造であると、前記上金型３と下金型６とで被加工材料１５を加圧して加工を施す際のクラウン９からスライド２を下方へ押圧する力が極めて強く、スライド２及び上金型３は変形しやすく、クラウン９からの力に加えてボルスタ５のベッド４による支持が下面周縁部のみで、この下面周縁部以外はボルスタ５の下方は空間が形成されているので更に変形しやすく、上金型３とスライド２は上方へ反るように変形すると共に下金型６とボルスタ５は下へ反るように変形し、被加工材料１５を均一に押せなくなり、被加工材料１５の製品としての精度が落ちることとなる。 And although not shown in figure, the upper metal mold | die 3 can be attached to the slide 2 with the same structure. However, with such an attachment structure, the force that presses the slide 2 downward from the crown 9 when the workpiece 15 is pressed by the upper mold 3 and the lower mold 6 to process is extremely strong. The slide 2 and the upper mold 3 are easily deformed, and in addition to the force from the crown 9, the bolster 5 is supported by the bed 4 only at the lower peripheral edge, and a space is formed below the bolster 5 except for the lower peripheral edge. Therefore, the upper mold 3 and the slide 2 are deformed so as to be warped upward, and the lower mold 6 and the bolster 5 are deformed so as to be warped downward, so that the work material 15 can be pressed uniformly. As a result, the accuracy of the work material 15 as a product is reduced.

そこで、図２などに示すように、上金型３のリブ３Ａとスライド２とで形成される空間３Ｂ及び下金型６のリブ６Ａとボルスタ５とで形成される空間６Ｂ内に支持体３０を配設する。しかも、前記支持体３０をスライド２の下面やボルスタ５の上面に一端部を固定し、他端部で前記被加工材料１５を加工するための前記上金型３の成形面の裏面（上面）３Ｃや下金型６の成形面の裏面（下面）６Ｃを押圧した状態或いは前記上金型３の成形面の裏面（上面）３Ｃや下金型６成形面の裏面（下面）６Ｃとは隙間を存した状態又は隙間を存しない状態で前記空間３Ｂ、６Ｂ内に配設する。 Therefore, as shown in FIG. 2 and the like, a support 30 is provided in a space 3B formed by the rib 3A of the upper mold 3 and the slide 2 and in a space 6B formed by the rib 6A of the lower mold 6 and the bolster 5. Is disposed. Moreover, one end of the support 30 is fixed to the lower surface of the slide 2 or the upper surface of the bolster 5, and the rear surface (upper surface) of the molding surface of the upper mold 3 for processing the workpiece 15 at the other end. 3C and the back surface (lower surface) 6C of the molding surface of the lower mold 6 are pressed, or the back surface (upper surface) 3C of the molding surface of the upper mold 3 and the back surface (lower surface) 6C of the molding surface of the lower mold 6 It is arranged in the spaces 3B and 6B in a state where there is no gap or in a state where there is no gap.

以下、図８乃至図１２に基づき、この支持体３０について詳述する。先ず、直方体形状の固定台３１がスライド２の下面やボルスタ５の上面に固定され、中央部に角部が円弧状に形成された角孔３２及び所定縁部に角孔３３が開設された取付台３４が各角部においてボルト３５を介して前記固定台３１上に固定される。 Hereinafter, the support 30 will be described in detail with reference to FIGS. First, a rectangular parallelepiped-shaped fixing base 31 is fixed to the lower surface of the slide 2 or the upper surface of the bolster 5, and a square hole 32 having a corner formed in an arc shape at the center and a square hole 33 formed at a predetermined edge are provided. A base 34 is fixed on the fixed base 31 via bolts 35 at each corner.

３７は円柱状の作動駒で、中央部に断面形状が円形の案内孔３６が開設されると共に上面の対称位置には高さレベルが異なる段差部３８、３８が形成される。即ち、この高さレベルの異なる各段差部３８の最下部から反時計回りで最上部に向けて徐々に高くなるように連続した傾斜面３９が形成される。 Reference numeral 37 denotes a cylindrical operating piece, which has a guide hole 36 having a circular cross section at the center, and step portions 38 and 38 having different height levels are formed at symmetrical positions on the upper surface. That is, the continuous inclined surface 39 is formed so as to gradually increase from the lowermost portion of each stepped portion 38 having a different height level counterclockwise toward the uppermost portion.

４０は前記作動駒３７上に配設され該作動駒３７と同径の円柱状の押出駒で、上面中央部に規制溝４１が形成されると共に下面中央部にその下部周囲の一部が切除されて断面が長円形に形成された円柱状の案内ピン４２が下方に突設される。また、押出駒４０の下面の周縁部の対称位置には高さレベルが異なる段差部４４、４４が形成される。即ち、この高さレベルの異なる各段差部４４の最下部から反時計回りで最上部に向けて徐々に高くなるように連続した傾斜面４５が形成される。なお、前記傾斜面３９、４５は、各段差部３８、４４の最下部から反時計回りで最上部に向けて徐々に高くなるように連続して形成したが、これに限らず、各段差部３８、４４の最上部から反時計回りで最下部に向けて徐々に低くなるように連続して形成してもよく、言い換えると、最下部から時計回りで最上部に向けて徐々に高くなるように連続して形成してもよい。 Reference numeral 40 denotes a cylindrical push-out piece disposed on the operating piece 37 and having the same diameter as the operating piece 37. A restriction groove 41 is formed at the center of the upper surface, and a part around the lower portion is cut off at the center of the lower surface. Then, a cylindrical guide pin 42 having a cross section formed in an oval shape protrudes downward. Further, step portions 44 and 44 having different height levels are formed at symmetrical positions on the peripheral edge portion of the lower surface of the extrusion piece 40. That is, the continuous inclined surface 45 is formed so as to gradually increase from the lowermost portion of each stepped portion 44 having a different height level counterclockwise toward the uppermost portion. The inclined surfaces 39 and 45 are continuously formed so as to gradually increase from the lowermost part of the stepped parts 38 and 44 toward the uppermost part in the counterclockwise direction. 38, 44 may be continuously formed so as to gradually decrease from the uppermost part in the counterclockwise direction toward the lowermost part, in other words, gradually from the lowermost part toward the uppermost part in the clockwise direction. It may be formed continuously.

４６は高さ調整駒で、下面中央部に下方に突設した規制ピン（図示せず）が押出駒４０の前記規制溝４１内に上方から嵌合した状態でボルト４７を介して押出駒４０上に固定される。 Reference numeral 46 denotes a height adjusting piece, and a restricting pin (not shown) projecting downward from a central portion of the lower surface is fitted into the restricting groove 41 of the extruding piece 40 from above with a bolt 47 interposed therebetween. Fixed on top.

なお、前記傾斜面３９、４５は作動駒３７上面の全域、押出駒４０下面の全域に亘って形成しなくともよい。 The inclined surfaces 39 and 45 may not be formed over the entire area of the upper surface of the operating piece 37 and the entire area of the lower surface of the pushing piece 40.

従って、固定台３１上に固定された取付台３４上に作動駒３７を載置した状態で、高さ調整駒４６が固定された押出駒４０の案内ピン４２を作動駒３７の案内孔３６を貫通させて、更にこの案内ピン４２の下端部を取付台３４の角孔３２に嵌合させると、案内ピン４２の円筒状部分は案内孔３６に嵌合しているので作動駒３７は回動可能であるが、案内ピン４２下部の切除された断面が長円形の部分が角孔３２に嵌合しているので押出駒４０及び高さ調整駒４６は回動できない。 Therefore, in a state where the operation piece 37 is placed on the mounting base 34 fixed on the fixed base 31, the guide pin 42 of the push piece 40 to which the height adjustment piece 46 is fixed is inserted into the guide hole 36 of the operation piece 37. When the lower end portion of the guide pin 42 is further fitted into the square hole 32 of the mount 34, the cylindrical portion of the guide pin 42 is fitted into the guide hole 36, so that the operating piece 37 rotates. Although it is possible, since the cut-out cross-section of the lower part of the guide pin 42 is fitted in the square hole 32, the push piece 40 and the height adjustment piece 46 cannot rotate.

また、固定駒４９の上面中央部に上下方向に延びて開設された収納溝５０内に側面部にその回動軸線方向と直交する方向に螺子孔５１が開設された回動軸体５２が回動可能に上方向から挿入され、この固定駒４９の下部は前記取付台３４の角孔３３に挿入され位置決め固定される。一方、作動駒３７の側面に突設された取付部５４の上面中央部に上下方向に延びて開設された取付溝５５内に側面部にその回動軸線方向と直交する方向に孔５６が開設された軸体５７が回動可能に上方向から挿入される。そして、取付部５４の側面には貫通孔５８が開設されると共に固定駒４９の側面にも貫通孔５９が開設される。 In addition, a rotating shaft body 52 in which a screw hole 51 is formed in a side surface portion in a direction perpendicular to the rotating axis direction in a storage groove 50 that extends in the vertical direction at the center of the upper surface of the fixed piece 49 is rotated. It is movably inserted from above, and the lower part of the fixed piece 49 is inserted into the square hole 33 of the mounting base 34 and fixed. On the other hand, a hole 56 is formed in the side surface of the mounting groove 55 that extends in the vertical direction at the center of the upper surface of the mounting portion 54 protruding from the side surface of the operating piece 37 in a direction perpendicular to the rotational axis direction. The shaft body 57 thus inserted is rotatably inserted from above . A through hole 58 is opened on the side surface of the mounting portion 54 and a through hole 59 is also opened on the side surface of the fixed piece 49.

従って、高さ調整用ボルト６０が作動駒３７の側面に突設された取付部５４の側面に水平方向に開設された貫通孔５８、軸体５７の孔５６及び固定駒４９の側面に水平方向に開設された貫通孔５９を介して回動軸体５２の螺子孔５１に螺合し、この高さ調整用ボルト６０を回動させることにより、前記軸体５７が高さ調整用ボルト６０に沿って移動することによって、作動駒３７が前記押出駒４０の案内ピン４２を支点として回動することとなる。この作動駒３７の回動により、図９に示すように、作動駒３７の段差部３８、３８と押出駒４０の段差部４４、４４とが近接しているときには、スライド２の下面やボルスタ５の上面からの高さ調整駒４６の高さレベルは最も低く（図９及び図１０参照）、逆に図１１に示すように、両段差部３８、３８と４４、４４とが離れるにつれて高くなる（図１３参照）。 Accordingly, the height adjusting bolt 60 is horizontally provided on the side surface of the mounting portion 54 projecting from the side surface of the operating piece 37 in the horizontal direction, the through hole 58 formed in the horizontal direction, the hole 56 of the shaft body 57, and the side surface of the fixing piece 49. The shaft body 57 is turned into the height adjusting bolt 60 by being screwed into the screw hole 51 of the rotating shaft body 52 through the through-hole 59 opened in, and rotating the height adjusting bolt 60. By moving along, the operating piece 37 rotates with the guide pin 42 of the pushing piece 40 as a fulcrum . 9, when the stepped portions 38 and 38 of the operating piece 37 and the stepped portions 44 and 44 of the pushing piece 40 are close to each other as shown in FIG. The height level of the height adjustment piece 46 from the top surface is the lowest (see FIG. 9 and FIG. 10), and conversely, as shown in FIG. (See FIG. 13).

即ち、支持体３０の高さレベルの調整動作を模式的に表した作動駒３７、押出駒４０等の展開図である図１３において、この図１３左部では作動駒３７の段差部３８、３８と押出駒４０の段差部４４、４４とが近接して高さ調整駒４６の高さレベルは最も低く、図１３右部では両段差部３８、３８と４４、４４とが離れて高い。 That is, in FIG. 13 which is a developed view of the operating piece 37, the pushing piece 40, etc. schematically showing the adjustment operation of the height level of the support 30, in the left part of FIG. And the stepped portions 44 and 44 of the extrusion piece 40 are close to each other, and the height level of the height adjusting piece 46 is the lowest, and in the right part of FIG.

この場合、前記高さ調整用ボルト６０の頭部の近くの軸部には周囲に案内溝６０Ａが開設され、前記高さ調整用ボルト６０が回動した際に軸体５７に上面から開設されて前記孔５６に連通する収納孔６１に螺合したガイドピン６２の下端部が前記案内溝６０Ａに沿って案内されるので、前記高さ調整用ボルト６０と共に取付部５４（作動駒３７）が移動することとなる。 In this case, a guide groove 60A is formed around the shaft near the head of the height adjusting bolt 60, and is opened from the upper surface of the shaft body 57 when the height adjusting bolt 60 is rotated. Since the lower end portion of the guide pin 62 screwed into the storage hole 61 communicating with the hole 56 is guided along the guide groove 60A, the mounting portion 54 (operating piece 37) is mounted together with the height adjusting bolt 60.

作業者がこの高さ調整用ボルト６０の回動による高さ調整駒４６の高さレベルを把握するために、目盛６６が付されると共に位置決め用のラック部６７が形成された位置決め部材６８をネジ６９により固定された取付部材７０の２つの下部突部が前記取付台３４に開設された取付孔６５、６５に挿入されて取付部材７０がネジ７２により取付台３４に固定されているので、作業者は前記目盛６６を見ながら、前記ラック部６７が作動駒３７の側面に形成された位置決め用のラック部７１に噛合した所望の位置でネジ６９を回動させることにより位置決め固定することができる（図１２参照）。 In order for the operator to grasp the height level of the height adjusting piece 46 by the rotation of the height adjusting bolt 60, a positioning member 68 provided with a scale 66 and a positioning rack portion 67 is provided. Since the two lower protrusions of the mounting member 70 fixed by the screw 69 are inserted into the mounting holes 65 and 65 formed in the mounting base 34 and the mounting member 70 is fixed to the mounting base 34 by the screw 72, While looking at the scale 66, the operator can fix the positioning by rotating the screw 69 at a desired position where the rack portion 67 is engaged with the positioning rack portion 71 formed on the side surface of the operating piece 37. Yes (see FIG. 12).

以上のように、前記上金型３をスライド２に、また下金型６をボルスタ５に取り付ける前に、これらスライド２、上金型３、ボルスタ５及び下金型６のたわみを極力少なくすべく、両金型３、６の空間３Ｂ、６Ｂ内に収まるように前記スライド２、ボルスタ５の適宜の位置に適宜の数の支持体３０を取り付ける。 As described above, before the upper die 3 is attached to the slide 2 and the lower die 6 is attached to the bolster 5, the deflection of the slide 2, the upper die 3, the bolster 5 and the lower die 6 is reduced as much as possible. Therefore, an appropriate number of support bodies 30 are attached to appropriate positions of the slide 2 and the bolster 5 so as to be accommodated in the spaces 3B and 6B of the molds 3 and 6, respectively.

しかも、この支持体３０の高さ調整駒４６のスライド２下面やボルスタ５上面からの高さレベルを高さ調整用ボルト６０の回動により調整できるので（図１３参照）、更には作業者はこの高さ調整用ボルト６０の回動による高さ調整駒４６の高さレベルを把握するために目盛６６を見ながら調整することができるので（図１２参照）、一目瞭然に且つ確実に適宜な高さレベルに調整することができる。 Moreover, the height level of the support 30 from the lower surface of the slide 2 and the upper surface of the bolster 5 can be adjusted by rotating the height adjusting bolt 60 (see FIG. 13). Since it can be adjusted while looking at the scale 66 in order to grasp the height level of the height adjusting piece 46 due to the rotation of the height adjusting bolt 60 (see FIG. 12), the appropriate height can be clearly and surely understood. Can be adjusted to the level.

これにより、前記空間３Ｂ、６Ｂ内の適宜位置に支持体３０を配設することにより、両金型の強度を増加させることができ、被加工材料１５を加圧して加工を施す際に、上金型３及び下金型６の変形、詳述すると、前記上金型３の成形面及び下金型６の成形面の変形を、前記上金型３の成形面の裏面３Ｃ及び下金型６の成形面の裏面６Ｃを各支持体３０で押圧することにより極力防止でき、被加工材料１５の製品としての精度が落ちることが防止される。 Thus, the space 3B, by arranging the support body 30 at an appropriate position within 6B, it is possible to increase the strength of the molds, when subjected to processing pressurizes the material to be processed 15, the upper Deformation of the mold 3 and the lower mold 6, more specifically, the deformation of the molding surface of the upper mold 3 and the molding surface of the lower mold 6, the rear surface 3C of the molding surface of the upper mold 3 and the lower mold 6 can be prevented as much as possible by pressing the back surface 6C of the molding surface with each support 30, and the accuracy of the work material 15 as a product is prevented from being lowered.

以上が、前記支持体３０の高さ調整駒４６のスライド２下面やボルスタ５上面からの高さレベルを作業者が手動で調整できる実施形態であるが、次に自動で調整できる実施形態につき、図１４に基づき説明する。この場合、第１の実施形態で用いた図番と同一の図番は同一の機能又は類似の機能を果たすものであり、第１の実施形態と異なる点についてのみ説明する。 The above is an embodiment in which the operator can manually adjust the height level from the lower surface of the slide 2 and the upper surface of the bolster 5 of the height adjusting piece 46 of the support 30. This will be described with reference to FIG. In this case, the same drawing numbers as those used in the first embodiment perform the same or similar functions, and only differences from the first embodiment will be described.

先ず、８０は駆動モータで、その出力軸に固定された歯車８１に支持台８２に支軸８３が支持された歯車８４が噛合する。そして、取付台３４に固定された一対の支持片８５に回動可能に支持されたウォーム歯車８６の軸部と前記支軸８３との間にタイミングベルト８７が張架されている。また、作動駒３７等を挟んだ前記一対の支持片８５及びウォーム歯車８６と対向する位置に、同様に一対の支持片８５及びウォーム歯車８６が設けられる。そして、前記作動駒３７の周側部に全周に亘って形成された歯車８８に前記ウォーム歯車８６、８６が噛合している。 First, 80 is a drive motor, and a gear 84 having a support shaft 83 supported by a support 82 is engaged with a gear 81 fixed to the output shaft. A timing belt 87 is stretched between the shaft 83 of the worm gear 86 rotatably supported by a pair of support pieces 85 fixed to the mount 34 and the support shaft 83. Similarly, a pair of support pieces 85 and a worm gear 86 are provided at positions facing the pair of support pieces 85 and the worm gear 86 with the operation piece 37 and the like interposed therebetween. The worm gears 86 and 86 are meshed with a gear 88 formed on the peripheral side of the operating piece 37 over the entire circumference.

従って、駆動モータ８０が駆動すると、歯車８１、８４が回転し、タイミングベルト８７を介してウォーム歯車８６が回転するので、歯車８８を介して前記作動駒３７が回動することにより、前述したように、支持体３０の高さ調整駒４６のスライド２下面やボルスタ５上面からの高さレベルを調整できる。 Therefore, when the drive motor 80 is driven, the gears 81 and 84 are rotated, and the worm gear 86 is rotated via the timing belt 87. Further, the height level of the height adjusting piece 46 of the support 30 from the lower surface of the slide 2 and the upper surface of the bolster 5 can be adjusted.

なお、スライド２下面やボルスタ５上面に固定された固定台３１上に取付台３４を固定するようにしたが、両台を当初より一体に構成してもよく、また押出駒４０と高さ調整駒４６とを固定するようにしたが、両駒を当初より一体に構成してもよい。 Although the mounting base 34 is fixed on the fixing base 31 fixed to the lower surface of the slide 2 or the upper surface of the bolster 5, both the bases may be integrally formed from the beginning, and the height of the extrusion piece 40 is adjusted. Although the piece 46 is fixed, both pieces may be integrally formed from the beginning.
