Description

Technical Field

[0001] This utility model relates to the field of die holder technology, and in particular to a die holder that improves safety. Background Technology

[0002] A die holder is a support structure for stamping dies. Its main function is to bear the weight of the die and the impact force during the stamping process, ensuring the stability and precision of the die during operation. The announcement number is CN217700992U. A high-safety lifting die frame is described. This equipment features a lifting die base structure, a lifting load-bearing structure, and a buffer seat structure. During operation, hydraulic cylinders A and B work simultaneously. When hydraulic cylinder A extends, hydraulic cylinder B retracts, ensuring that the buffer plate does not contact the extension plate, thus avoiding interference with the normal stamping operation of the upper die base. In the event of a malfunction of hydraulic cylinder A causing the upper die base to fall unexpectedly, the buffer plate, in conjunction with springs and the load-bearing plate, provides cushioning and shock absorption support for the extension plate, thereby cushioning and shock absorption support for the upper die base. This effectively prevents the upper die base from falling rapidly and injuring workers, significantly reducing safety hazards and improving safety. However, when compacting raw materials, misalignment and displacement may occur, causing workpieces to pop out and injure workers. Furthermore, after the die is completed, manual removal of the die from the lower die surface is required, which may result in injury due to operational errors. Therefore, designing a die frame with improved safety is a pressing issue that needs to be addressed. Utility Model Content

[0006] Preferably, the T-slot fits into the surface of the movable block one, and there are four sets of clamping devices, which are symmetrically distributed on the surface of the fixed block one. The movable block and the movable block one are adjusted and fixed by bolts and nuts. Here, four sets of clamping devices are designed, with two sets forming one large set, which can flexibly fix the long strip of raw material on the surface of the upper mold, reducing displacement and the phenomenon of workpiece ejection that may accidentally injure workers.

[0007] Preferably, the protective device includes a second fixing block, the surface of which has a second slot, a second spring fixedly connected to the surface of the second slot, a protective plate fixedly connected to the other end of the second spring, and a punch fixedly connected to the surface of the second fixing block. Here, when the upper mold is compacted, the generated model will bounce to a certain extent, and the protective plate provides some blocking effect.

[0008] Preferably, the second fixing block and the protective plate are circular in shape, and the number of the second springs is ten sets, which are distributed equidistantly around the circumference. Here, the circular protective plate and the ten sets of springs make its extension and retraction smoother.

[0009] Preferably, the lower surface of the worktable has a mold outlet, and a fixing block three is fixedly connected to the lower surface of the worktable. A mold storage chamber is slidably connected to the surface of the fixing block three. Here, the generated model does not need to be manually removed; it is only necessary to clean the mold in the mold storage chamber in a timely manner.

[0010] Preferably, the surface of the fixing block three is provided with a slot four, and the two sides of the mold storage compartment are provided with slot three. Here, the fixing block three can be easily separated from the mold storage compartment through the slot four and slot three.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the clamping device can fix the material to be processed, adapting to materials of various sizes, reducing the phenomenon of workpieces popping out and accidentally injuring workers, thus improving safety. The protective device can partially block the mold with a certain size after production, reducing the phenomenon of popping out. The cooperation of hydraulic cylinder A, buffer plate, spring three and hydraulic cylinder B can reduce the safety risk of the upper mold falling due to the detachment or damage of hydraulic cylinder A, causing unnecessary damage, and also facilitates maintenance by the staff.

[0013] 2. In this utility model, through the cooperation of the mold outlet, the fixing block three and the mold storage bin, the generated model can be automatically put into the mold storage bin. There is no need for manual removal. It is only necessary to clean the mold in the mold storage bin in time, which reduces the risk of worker injury due to operational errors.

[0022] Example 1

[0023] Please see Figure 1-3 This utility model provides a technical solution: a punching die holder with improved safety, including a worktable 1. A clamping device 2 and a support frame 3 are fixedly connected to the surface of the worktable 1. The clamping device 2 includes a fixing block 20, the surface of which has a T-slot 21. A motor 22 and a hydraulic cylinder A4 are fixedly mounted on the surface of the support frame 3. A positive and negative screw 23 is fixedly connected to the output end of the motor 22. A moving block 24 is threadedly connected to the surface of the positive and negative screw 23. A spring 28 is fixedly connected to the surface of the moving block 24, and a movable block 2 is fixedly connected to the other end of the spring 28. 7. The surface of the fixed block 20 is fixedly connected to the lower mold 25. The T-slot 21 fits against the surface of the movable block 24. There are four sets of clamping devices 2, which are symmetrically distributed on the surface of the fixed block 20. The movable block 27 and the movable block 24 are adjusted and fixed by bolts 26 and nuts 29. The design of four sets of clamping devices 2, with two sets forming one large set, can flexibly fix the long strips of raw materials on the surface of the upper mold 5, reducing displacement and the phenomenon of workpiece ejection that may injure workers. The output end of the hydraulic cylinder A4 is fixedly connected to the upper mold 5, and the surface of the upper mold 5 is fixedly connected to... The support frame 3 is equipped with a protective device 7. A slot 6 is provided on the side of the support frame 3. A hydraulic cylinder B8 is fixedly connected to the lower surface of the support frame 3. A carrying plate 16 is fixedly connected to the output end of the hydraulic rod. A spring 9 is fixedly connected to the surface of the carrying plate 16. A buffer plate 15 is fixedly connected to the other end of the spring 9. When the hydraulic cylinder A4 suddenly stops working, causing the upper mold 5 to drop sharply, it first contacts the buffer plate 15. This, in conjunction with the spring 9, prevents the upper mold 5 from directly contacting the lower mold 25, thus avoiding unnecessary damage. It also facilitates maintenance by personnel. The protective device 7 includes a fixing block 71. The surface of the second block 71 has a slot 72, and a spring 73 is fixedly connected to the surface of the slot 72. A protective plate 75 is fixedly connected to the other end of the spring 73. A punch 74 is fixedly connected to the surface of the second block 71. When the upper mold 5 is pressed, the generated model will bounce to a certain extent. The protective plate 75 has a certain blocking effect. The shape of the second block 71 and the protective plate 75 is circular. There are ten sets of springs 73. The ten sets of springs 73 are distributed equidistantly in a circle. The circular protective plate 75 and the ten sets of springs 73 can make it smoother when it extends and retracts.

[0024] Example 2

[0025] Please see Figure 4 The lower surface of the workbench 1 is provided with a mold outlet 13. A fixing block 3 12 is fixedly connected to the lower surface of the workbench 1. A mold storage chamber 10 is slidably connected to the surface of the fixing block 3 12. The generated model does not need to be manually removed. It is only necessary to clean the mold in the mold storage chamber 10 in time. A slot 4 14 is provided on the surface of the fixing block 3 12. A slot 3 11 is provided on both sides of the mold storage chamber 10. The fixing block 3 12 can be easily separated from the mold storage chamber 10 through the slot 4 14 and the slot 3 11.

[0026] Working principle: When using this equipment, the user first needs to adjust the position of the clamping device 2 according to the width of the material to be processed. Starting the motor 22 can control the moving block 24 to move synchronously to the left or right on the surface of the positive and negative screws 23. By rotating the nut 29, the height between the moving block 24 and the movable block 27 can be adjusted. After the adjustment is completed, the hydraulic cylinder A4 is started to drive the upper mold 5 to move downward. When the punch 74 contacts the lower mold 25, the model is initially formed. When the hydraulic cylinder A4 moves upward, complete separation is achieved, and the model will enter the mold outlet 13 and enter the mold storage bin 10. The worker only needs to clean the mold storage bin 10, which is almost full, to complete the punching work. At the same time, considering that the elasticity and density of the processed materials are different, some materials will have a certain degree of pop-out during punching. The cooperation of the fixed block 71 driven by the upper mold 5, the punch 74, the spring 73 and the protective plate 75 can reduce the risk of workpiece pop-out to a certain extent. At the same time, the punching area is separated from other areas of the worktable 1, which increases the safety of the equipment.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
