The present invention relates to a restraining shearing device for bar-shaped metal materials in which the obtained material has a high perpendicularity on the cut surface and is less deformed.

ラム７の駆動により圧下される。 The production of desired lengths from round steel or other rod-shaped metal materials is generally done by cutting or shearing.
A band saw is usually used for cutting, and for shearing, a lower blade 3 having a material through hole 2 corresponding to the cross-sectional shape of the material 1 to be sheared, as shown in FIG. It has a fixed-size stopper 4 that abuts the tip of the material to be sheared 1 inserted into the lower blade 3, and an upper blade 5 that descends in close sliding contact with the front surface of the lower blade 3 and shears the material to be sheared 1. Shearing device A is used. The lower blade 3 is fixed to the bed 6 side, and the upper blade 5 is fixed to the ram (slide) 7 side and is rolled down by the drive of the ram 7.

り速度を高めなければ作業能率を向上できない。 When a long material to be sheared 1 is sheared by the shearing device having the above structure, the material obtained by shearing has a length l corresponding to the distance between the lower blade 3 and the sizing stopper 4. However, although the part near the lower blade 3 receives downward pressure from the upper blade 5, the tip surface is only in surface contact with the sizing stopper 4 and is free in the vertical direction, so if the l dimension becomes longer, The tip side tends to float slightly, and the perpendicularity of the cut on the rear end surface, that is, the sheared surface, may decrease. On the other hand, the sheared material 1 is sent out intermittently.
The end surface of the
Since the sizing stopper 4 is abutted against the sizing stopper 4, the sizing stopper 4 is easily worn out. Further, since the pieces are sheared one by one intermittently, work efficiency cannot be improved unless the lifting speed of the ram 7 and the feeding speed of the sheared material by the feed rollers 9 are increased.

Press down 8. As a result, the first upper blade 29 and the first
The lower blade 11, the second upper blade 30, and the second lower blade 12 simultaneously shear the sheared material 1 at two locations.

のせん断面でせん断された材料となる。 At this time, the material 1 to be sheared is the first lower blade 11 and the second lower blade 11.
Both ends of the part facing between the lower blade 12 are pushed evenly by the first upper blade 29 and the second upper blade 30, and the tip of the sheared material 1 that is about to jump is pressed by the sizing stopper 23. Since the protrusion 38 prevents the blade from floating, both ends of the portion facing between the second lower blade 12 and the sizing stopper 23 are pressed down from above. That is, the materials obtained two at a time from the sheared material 1 are both materials sheared along the vertical shear plane.
また、同時にl1とl2の長さの材料を得るので、
l1＝l2であれば加工速度が倍加したことになり、
またl1とl2の長さが異る場合は、２種類を同時に

If l 1 = l 2 , the machining speed has doubled,
Also, if the lengths of l 1 and l 2 are different, two types will be obtained at the same time, which will double the efficiency.
さらに、２個同時の拘束せん断であるため、加
工量に対する定寸ストツパの使用回数が1/2とな
つて定寸ストツパの損耗は大幅に減少する。 Furthermore, since two pieces are simultaneously restrained and sheared, the number of times the sizing stopper is used is halved relative to the amount of processing, and wear and tear on the sizing stopper is greatly reduced.
以上の説明から明らかなように、本発明は、従

The service life of the product can also be extended. Furthermore, in the present invention, since the material to be cut is cut in parallel, the surface pressure on the surface of the upper blade that contacts the workpiece is reduced, and the life of the blade is extended.

Furthermore, since the lower blade holder of the first lower blade is elastically supported on the bed side in a slightly floating state, it becomes easy to insert the material to be sheared, and the work efficiency can be further improved.
