Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-stage press device equipped with a plurality of press plates or hot plates, and particularly relates to a structure for placing a pressurized object on the press plates or hot plates. be.

Conventionally, press plates or hot plates are provided in multiple stages between an upper plate and a lower plate, and a feed plate (coal plate) is used, in which a predetermined pressurized object is placed on each of the press plates or hot plates. ) is fed in, and the pressurized object is simultaneously pressed by the compression action of the J upper plate and the lower plate.

Therefore, in such a multi-stage press device, when feeding the feed plate on which the pressurized object is placed to a predetermined position on the press plate or hot plate, it is necessary to move the feed plate on the press plate or hot plate. Generally, the press plate and hot plate are fed by sliding, and the surfaces of the press plate and hot plate are worn out due to the sliding movement, which limits the precision of pressing the object to be pressed.

In particular, in the case of hot pressing using a hot plate, the thickness of the feed plate is made thin in consideration of heat transfer to the pressurized object, which increases the weight of the pressurized object. In this case, the feed plate will be fed onto the hot plate in a bent state, and the hot plate will be locally worn out, making the above-mentioned disadvantage more noticeable. The present invention was made against the background of the above-mentioned circumstances, and its purpose is to prevent wear and tear of the press plate, etc. when feeding the feed plate on which the pressurized object is placed; An object of the present invention is to provide a multi-stage press device in which press precision is maintained well. In order to achieve such an object, the present invention provides the multi-stage press device, in which a roller stand independent from the press disk or hot plate is arranged on the side of the press disk or the hot plate, and the roller stand is arranged on the side of the press disk or the hot plate. A support means capable of supporting the feed plate is provided, and the feed plate is moved in a floating state over the press plate or hot plate while being supported by roller stands supported by the support means on both sides thereof. On the other hand, by lowering the feed plate or raising the press plate or hot plate, the feed plate is placed on the press plate or the hot plate. In this way, when the feed plate carrying the pressurized object is fed onto the press plate or hot plate, the sliding between the feed plate and the press plate or hot plate is completely eliminated. The surface accuracy of the pressing machine, etc. is maintained for a long time, and its lifespan is greatly improved.The work required to maintain the accuracy of the pressing machine, etc., which was previously required, is eliminated, and the precision of the pressing machine for the pressurized object is improved. It is well maintained.

In addition, local wear caused by bending of the feed plate can be easily eliminated by appropriately setting the height of the roller stand that supports the feed plate. Next, in order to clarify the present invention more specifically,
An embodiment of the present invention will be described in detail based on the drawings.

First, in FIGS. 1 and 2, an uplift cylinder 12 is fixed on a base 10, and a movable platen 16 as a lower plate is attached to a ram 14 of the uplift cylinder 12. There is.

Further, a fixed platen 18 as an upper plate is attached to an upper frame (not shown) that is fixed in position with respect to the base 10, and a support device (not shown) is provided between the fixed platen 18 and the movable platen 16. A plurality of hot plates 20 are disposed, which are supported at predetermined intervals by. A feed plate 24 on which a laminated plate 22 as a pressurized object is placed is fed from a rotor 26 onto the hot plates 20, and a movable plate 16 is connected to a thrust cylinder 12. The plurality of laminated plates 22 respectively placed on the hot plate 20 are pushed up by the
8 and are pressed together at the same time to create a hot breath. The laminated plate 22 is, for example, a large number of thin ferrite plates laminated between three stainless steel mirror plates, and is strongly bonded by hot pressing. Here, roller stands 32 are arranged near the hot plates 20 in this embodiment, and the feed plate 24 fed from the rotor 26 is supported by the roller stands 32 and heated. It is designed to be able to move on the board 20 in a floating state.

As shown in FIG. 3, the roller stand 32 includes a rectangular box frame 34 arranged to surround the hot plate 20 with a slight gap from the side surface of the hot plate 20, and the box frame. A side plate 36 is fixed at a predetermined distance from the box frame 34 on both sides of the feed plate 34, that is, on the outside of both sides parallel to the feeding direction of the feed plate 24. Four rollers 38 are rotatably mounted between the box frame 34 and the side plates 36 in the feeding direction of the feed plate 24, and in such a manner that their upper ends protrude slightly upward from the upper edges of the box frame 34 and the side plates 36. ing. In addition, both ends of the side plates 36, that is, the box frame 3
A feed roller 40 and a feed roller 42 are rotatably attached to the portions protruding from the roller 4, respectively. The roller stand 32 is supported by four sets of support devices 44 as supporting means provided near both sides of the roller stand 32.

As clearly shown in FIG. 2, the support device 44 includes a support plate 48 as a support member having the same number of support claws 46 as the roller bases 32, and a support plate 48 that supports vertical movement of the support plate 48. The hydraulic cylinder 54 is provided with a pair of parallel links 50 that allow the support plate 48 to move upward and downward, and a hydraulic cylinder 54 that is connected to the lower end of the support plate 48 and serves as a lifting means for driving the support plate 48 in the vertical direction. 54 and the parallel link 50 are
They are attached to brackets 56 and 58 fixed to the base 10 or fixed platen 18, respectively.

Therefore, when the rod 52 of the hydraulic cylinder 54 is in the protruding state, the support plate 48 as shown in FIG.
is positioned at an upper support position, and its support claws 46 are engaged with the lower edges of the respective roller stands 32 to support the roller stands 32. At this time, the roller stand 32
The upper end of the roller 38 protrudes above the upper surface of the hot plate 20 by a predetermined distance when the hot plate 20 is in an open position supported by a support device (not shown). On the other hand, when the rod 52 of the hydraulic cylinder 54 is retracted, the support plate 48 is located at the lower retracted position, as shown in FIG. Note that this retracted position is not directly below the support position, but is displaced in a direction away from the roller stand 32 due to the action of the parallel link 50.
On the other hand, at the four corners of the lower end of the hot plate 20, there are projecting receiving plates 60 as receiving parts that are perpendicular to the feeding direction of the feeding plate 24 and protrude in the horizontal direction.
The receiving plate 60 supports the roller stand 32 when the roller stand 32 is in the retracted position.

At this time, the roller stand 32 is supported such that the upper end of the roller 38 is slightly lower than the upper surface of the hot plate 20. Next, the operation of this embodiment will be explained.

First, the rods 52 of the four hydraulic cylinders 54 are pushed out, the support plate 48 is positioned at an upper support position, and the roller stand 32 is supported by the support plate 48 .

In this state, the plurality of feed plates 24 on which the laminated plates 22 are placed, which are already accommodated in the rotor 26,
They are simultaneously fed onto the hot plate 20 by a feed arm (not shown). At this time, both sides of the feed plate 24 are supported by the rollers 38 of the roller stand 32, as shown in FIG. 2, and the feed plate 24 is moved in a floating state without contacting the hot plate 20. FIGS. 1 and 2 show this state. Here, since the feed plate 24 of this embodiment is made thin so that the heat of the hot plate 20 can be efficiently transferred to the laminated plate 22, by supporting both sides of the feed plate 24, as shown in FIG. As shown in the figure, the central part is bent, but the supporting position of the support plate 48 that supports the roller stand 32 is set in consideration of the amount of bending of the feed plate 24 so that the feed plate 24 and the hot plate 20 do not come into contact with each other. It is set at a position that supports the roller stand 32.

Further, when the feed plate 24 is moved on the rollers 38, the roller stand 32 is also moved in the feeding direction of the feed plate 24, but the roller stand 32 is arranged so as to surround the hot plate 20. Therefore, the movement is due to the box frame 3 of the roller stand 32.
4 is regulated by contacting the hot plate 20. In this way, when the feed plate 24 is moved to a predetermined position on the hot plate 20, the hydraulic cylinder 5
The rod 52 of No. 4 is retracted to position the support plate 48 at the retracted position.

At this time, since the roller stand 32 is moved downward together with the support plate 48, the feed plate 24 supported by the roller stand 32 is placed on the hot plate 20, and
The roller stand 32 is supported on the side of the hot plate 20 by a receiving plate 60 protruding from the hot plate 20. FIG. 4 shows this state. And the thrust cylinder 12
By pushing up the movable platen 16, the plurality of laminated plates 22 are simultaneously pressed and hot-breathed.

At this time, since the support plate 48 is retracted to a position away from the roller stand 32, there is no risk that the roller stand 32, which is moved together with the hot plate 20, will engage with the support claws 46 of the support plate 48. be. When the hot press is finished and the movable platen 16 is returned to the lower position, the support plate 48 is brought back to the support position and the feed plate 24 is supported by the roller stand 32. Then, the feed plate 24 on which a new laminate 22 is placed is sent from the rotor 26, and the feed plate 24 on which the new laminate 22 is placed is fed by the fed feed plate 24. The plate 24 is pushed out to an unloader (not shown) (usually provided on the opposite side of the rotor 26), and then the same operation as described above is repeated. As described above, according to this embodiment, when the feed plate 24 on which the laminate plate 22 is placed is fed onto the hot plate 20 or sent out from the hot plate 20, the feed plate 24 is 24 and the hot plate 20 do not slide at all, so their wear and tear is eliminated.

Therefore, the surface precision of the feed plate 24 and the hot plate 20 is maintained well, and their lifespan is greatly improved, and a product with high press precision can be stably obtained.
In addition, complicated work such as polishing the surface of the hot plate 20, which was conventionally required to maintain press accuracy, is eliminated, making maintenance work of the device easier and increasing the operating rate. . Also, a support plate 48 that supports the roller stand 32
Since the support position of is set in consideration of the deflection of the feed plate 24, sliding between the feed plate 24 and the hot plate 20 is prevented regardless of the deflection of the feed plate 24. Next, another embodiment of the invention will be described.

In the following description, the same reference numerals are given to the same parts as in the above-mentioned embodiment, and the description thereof will be omitted. 5 and 6, on both sides of the roller stand 32, two pillars 62 are installed between the base 10 and the fixed platen 18, and each of the pillars 62 has a support. A support plate 64 as a member is fixed.

The support plate 64 has a step-like shape in which the plate width is narrower at the top and wider at the bottom, and its upper edge 66 is connected to the heating plate 20 located at the uppermost position.
The first stepped portion 6 is located at approximately the same height as the lower edge of the second heating plate 20.
8a is formed, and thereafter step portions are sequentially formed at approximately the same height as the lower edge of the heating plate 20, and the last step is formed at approximately the same height as the lower edge of the heating plate 20 located at the lowest position. step part 6
8n is formed. On the other hand, the side plate 36 of the roller stand 32
Engagement rods 70 are protruded from the lower end edges of both sides to which the support plate 64 is fixed, respectively, at positions corresponding to the upper end edge 66 of the support plate 64 and the stepped portion 68a168n.

That is, a roller stand disposed around the periphery of the uppermost hot plate 20. 32 has a stepped portion 6 at a position where it can engage with the upper edge 66, and a stepped portion 6 on the roller stand 32 disposed around the periphery of the second hot plate 20.
8a, and finally, the lowermost one. The roller stand 32 disposed around the periphery of the hot plate 20 has a position where it can engage with the stepped portion 68n.
The engaging rods 70 are provided in a protruding manner, and the roller stands 32 of i are supported by the upper edge 66 and the stepped portion 68a168n, respectively.

The upper ends of the rollers 38 of the roller stand 32 supported in this way are brought to an open position where the movable platen 16 is positioned at a lower position and each hot plate 20 is supported by a support device (not shown). In the positioned state, it protrudes above the upper surface of the hot plate 20 by a predetermined dimension. Note that this predetermined dimension is a dimension that takes into consideration the amount of deflection of the feed plate 24, as in the case of the above-described embodiment.
In the case of this embodiment, when the ram 14 of the push-up cylinder 12 is retracted and the respective hot plates 20 are in the open position, the engagement rod 70 fixed to the roller stand 32 is connected to the support plate 64. It is supported by being engaged with the upper end edge 66 or the stepped portion 68a168n, respectively.

In other words, the support plate 64, the engagement rod 70, and the like constitute means for supporting the roller stand 32. In this state, as shown in FIGS. 5 and 6, the laminated plate 22
When the feed plate 24 on which the
is thrust out.

As a result, the hot plate 20 is raised, the feed plate 24 is placed on the hot plate 20, and the roller stand 32 is placed on the hot plate 20.
is supported by a receiving portion 60 protruding from the hot plate 20 as in the previous embodiment. Then, after the laminated plate 22 is hot-breathed, when the ram 14 is retracted and each hot plate 20 is returned to the open position, the roller stand 32 is again pressed against the upper edge 66 of the support plate 64 or the stepped portion 68a1.
68n, the feed plate 24 is supported in a floating state above the hot plate 20.

After that, the feed plate 2 on which a new laminate 22 is placed
4, the feed plate 24 on which the laminated plate 22 at the end of the hot breath is placed is pushed out, and the same operation as described above is repeated. Therefore, in this embodiment as well, the sliding between the feed plate 24 and the hot plate 20 during the feeding and feeding of the feed plate 24 is completely eliminated, and the same effects as in the previous embodiment can be obtained.

In addition, the support means for supporting the roller stand 32 is extremely simply constituted by the positionally fixed support plate 64, the engagement rod 70, etc., and the support means for supporting the feed plate 24 by the roller stand 32 and the support on the hot plate 20 are very simple. Since the mounting on the laminate board 22 is carried out in conjunction with the vertical movement of the hot plate 20 for hot-pressing the laminated board 22, there is an advantage that the pressing work can be performed in exactly the same manner as in the past. Although one embodiment of the present invention has been described in detail above, the present invention can be implemented in other embodiments as well.

For example, in the above-mentioned embodiments, the feed plate 2
Although the case where the sliding between the feed plate 24 and the hot plate 20 during feeding and feeding of No. 4 is eliminated, at least the sliding between the feeding plate 24 and the hot plate 20 during feeding is prevented. If so, the effects of the present invention can be obtained to some extent. The roller stand 32 also includes rollers 3 provided on both sides of the hot plate 20.
8, a feed roller 40 and a feed roller 42 are provided, but depending on the structure of the rotor 26 and the unloader (not shown), these rollers 40 and 42 may not necessarily be provided.

In addition, the roller stand 32 does not necessarily have to be constructed integrally; for example, a longitudinal roller stand having rollers 38 arranged in a row may be separately arranged on both sides of the hot plate 20.

In this case, in the embodiments shown in FIGS. 1 to 4, these roller stands may be fixed to the support claws 46 of the support plate 48. In addition, in the above-mentioned embodiments, the hot plate 2
Although the description has been made regarding a hot press device equipped with a pressurizer, it goes without saying that the same method can be applied to a press device equipped with a general press plate.

In addition, although no specific examples will be given, it goes without saying that the present invention can be implemented with various modifications and improvements based on the knowledge of those skilled in the art without departing from the spirit thereof.
