Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die with a floating punching die structure. Background Technology

[0002] A punching die is a commonly used metalworking tool used for punching, stamping, and shearing processes on metal sheets. A punching die mainly consists of a die base, die pillars, guide pillars, guide sleeves, ejector pins, a lower die, and a punch.

[0003] Currently, some existing punching dies adopt a floating die structure, which changes the traditional design where the die is fixed on the die base, allowing it to slide in the punching direction and achieve rapid material removal. However, some waste is generated when punching through the punching die. This waste is stored in the punching groove and is not easy to discharge. Therefore, it is urgent to design a punching die with a floating punching die structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a punching die with a floating punching die structure. Its advantage lies in pushing the waste material out of the waste discharge groove, achieving the effect of discharging punching waste material from the entire die.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punching die with a floating punching die structure includes a base and a top seat. Support and reset components are provided at the top of the base and the bottom of the top seat. A die seat is fixedly installed at the middle of the top of the base. A lower die is fitted onto the outer wall of the die seat. Floating components are provided at the four bottom corners of the lower die and the top of the base. A pad and an upper die are sequentially fixedly installed at the bottom of the top seat. A punching head is fixedly installed at the middle of the bottom of the upper die. A clamping component is provided at the bottom of the upper die. A punching groove is formed in the middle of the die seat, and the inner diameter of the top of the punching groove matches the outer diameter of the punching head. A waste discharge groove penetrating the die seat is formed at the bottom of the punching groove, and a waste discharge component is provided on the waste discharge groove.

[0007] The above technical solution promotes the removal of waste material from the waste discharge trough, thereby achieving the effect of discharging punching waste material from the entire mold.

[0008] The present invention is further configured such that the waste discharge assembly includes a support frame fixedly installed on one side of the top of the base, and a horizontal second rack plate is slidably arranged on one side of the top of the support frame. A pusher seat inserted into the waste discharge groove is fixedly installed at one end of the second rack plate, and a vertical first rack plate is slidably arranged at one end of the support frame. The top of the first rack plate is fixedly installed on one side of the bottom of the lower mold, and a toothed column is rotatably connected to the top of the support frame. Both the first rack plate and the second rack plate mesh with the toothed column.

[0009] The above technical solution enables the second rack plate and the pusher seat to reciprocate through the meshing action of the first rack plate, the tooth column, and the second rack plate, which facilitates the operation of the entire waste discharge assembly.

[0010] The present invention is further configured such that the top side and the inner wall of the support frame are respectively provided with horizontal and vertical sliding grooves, and the bottom of the second rack plate and the side of the first rack plate are respectively fixed with sliding seats that are slidably disposed in the two sliding grooves.

[0011] The above technical solutions ensure the stability of the first and second rack plates.

[0012] The present invention is further configured such that the support reset assembly includes a support cylinder fixedly installed at the two corners of the top of the base, and a second guide post inserted into the support cylinder is fixedly installed at the two corners of the bottom of the top base, and a third spring is fixedly installed at the bottom end of the second guide post and the bottom inner wall of the support cylinder.

[0013] The above technical solutions enable the top seat and upper die to have reset properties, facilitating the next punching operation.

[0014] The present invention is further configured such that an installation groove is provided at the top center of the top seat, and a mold handle is fixedly installed on the inner wall of the installation groove.

[0015] The above technical solution facilitates the connection between the mold handle and the hydraulic cylinder, allowing the hydraulic cylinder to apply pressure to drive the entire punching mold to work.

[0016] The present invention is further configured such that the floating component includes limiting posts fixedly installed at the four corners of the top of the base, and each of the four corners of the bottom of the lower mold is provided with an insertion hole. Each limiting post is fixedly provided with a first guide post inserted into the insertion hole, and a first spring is fixedly installed at the top of the first guide post and the bottom of the insertion hole.

[0017] The present invention is further configured such that the distance from the bottom of the lower mold to the top of the limiting post is the same as the distance from the top of the lower mold to the top of the mold base.

[0018] The above technical solution involves a floating die structure that forms the entire punching die, allowing the lower die to slide along the punching direction for rapid material removal.

[0019] The present invention is further configured such that the clamping assembly includes an annular groove formed at the bottom of the upper mold, and a clamping ring is inserted into the inner wall of the annular groove. A protective washer is fixed at the bottom of the clamping ring, and second springs are fixedly installed at equal distances and in annular distribution at the top of the clamping ring and the top of the annular groove. The bottom surface of the protective washer is lower than the bottom surface of the punching head.

[0020] The above technical solution ensures that the clamping ring contacts the workpiece before the punching head, holding the workpiece in place and guaranteeing its stability.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model, through the cooperation of the mold base, lower mold and floating components, forms a floating die structure for the entire punching die. During the pressing down of the upper mold, the top surface of the lower mold is flush with the top surface of the mold base, so that the punch head enters the punching groove, which facilitates the punching operation on the workpiece. After the punching is completed, the lower mold is reset, which drives the workpiece to reset, so that the lower mold can slide along the punching direction to achieve rapid material removal.

[0023] 2. This utility model, through the setting of a lower mold, mold base, punching groove, waste discharge groove and waste discharge component, during the lifting and lowering process of the lower mold, in conjunction with the meshing action of the first toothed plate, tooth column and the second toothed plate in the waste discharge component, drives the second toothed plate and the pusher seat to form a reciprocating motion, thereby pushing the waste material out of the waste discharge groove, and achieving the effect of discharging the punching waste material from the entire mold.

[0035] Reference Figure 1-6A punching die with a floating punching die structure includes a base 1 and a top seat 9. Support and reset components are provided on the top of the base 1 and the bottom of the top seat 9. A die holder 2 is fixedly installed at the center of the top of the base 1. A lower die 3 is sleeved on the outer wall of the die holder 2. Floating components are provided at the four bottom corners of the lower die 3 and the top of the base 1. An installation groove is opened at the center of the top of the top seat 9, and a die shank 10 is fixedly installed on the inner wall of the installation groove. The die shank 10 is connected to a hydraulic cylinder. Pads are sequentially fixedly installed at the bottom of the top seat 9. The base 11 has a plate 11 and an upper mold 12. A punch head 16 is fixedly installed at the bottom center of the upper mold 12. A clamping assembly is provided at the bottom of the upper mold 12. A punching groove 15 is provided at the center of the mold base 2. The inner diameter of the top of the punching groove 15 is adapted to the outer diameter of the punch head 16. A waste discharge groove 14 penetrating the mold base 2 is provided at the bottom of the punching groove 15. A waste discharge assembly 5 is provided on the waste discharge groove 14. The waste discharge assembly 5 includes a support frame 501 fixedly installed on one side of the top of the base 1. The top side of the support frame 501 slides. A horizontally oriented second rack plate 505 is provided, with a pusher seat 502 inserted into the waste discharge groove 14 fixedly installed at one end of the second rack plate 505. A vertically oriented first rack plate 506 is slidably provided at one end of the support frame 501, with the top end of the first rack plate 506 fixedly installed on one side of the bottom of the lower mold 3. A toothed column 504 is rotatably connected to the top of the support frame 501. Both the first rack plate 506 and the second rack plate 505 mesh with the toothed column 504. The top side and one inner wall of the support frame 501 are respectively opened. The mold is provided with horizontal and vertical slide grooves 503, and the bottom of the second rack plate 505 and one side of the first rack plate 506 are respectively fixed with slide seats 507 that are slidably disposed in the two slide grooves 503. During the lifting and lowering process of the lower mold 3, the meshing action of the first rack plate 506, the tooth column 504 and the second rack plate 505 in the waste discharge component 5 drives the second rack plate 505 and the pusher seat 502 to form a reciprocating motion, thereby pushing the waste material out of the waste discharge groove 14, and achieving the effect of discharging the punching waste material from the entire mold.

[0036] In order to allow the upper mold 12 to be reset, refer to... Figures 1-5 The support and reset assembly includes a support cylinder 7 fixedly installed at the two corners of the top of the base 1, and a second guide post 8 inserted into the support cylinder 7 is fixedly installed at the two corners of the bottom of the top seat 9. A third spring 20 is fixedly installed at the bottom end of the second guide post 8 and the bottom inner wall of the support cylinder 7. By using the above-mentioned support and reset assembly, the top seat 9 and the upper die 12 can have reset performance, which facilitates the next punching operation.

[0037] To achieve a floating die structure for the entire punching die, refer to... Figures 1-4The floating component includes limiting posts 4 fixedly installed at the four corners of the top of the base 1, and the bottom of the lower die 3 is provided with insertion holes at the four corners of the bottom. The top of each limiting post 4 is fixedly fitted with a first guide post 6 inserted into the insertion hole. The top of the first guide post 6 and the bottom of the insertion hole are fixedly installed with a first spring 19. The distance from the bottom of the lower die 3 to the top of the limiting post 4 is the same as the distance from the top of the lower die 3 to the top of the mold base 2. The above-mentioned floating component forms a floating die structure for the entire punching die. It can drive the top surface of the lower die 3 to be flush with the top surface of the mold base 2 during the pressing of the upper die 12, so that the punch head 16 enters the punching groove 15. After punching is completed, the lower die 3 is reset, which drives the workpiece to reset, so that the lower die 3 can slide along the punching direction to achieve rapid material removal.

[0038] To ensure workpiece stability, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The clamping assembly includes an annular groove 17 formed at the bottom of the upper die 12, and a clamping ring 13 is inserted into the inner wall of the annular groove 17. A protective washer is fixed at the bottom of the clamping ring 13, and a second spring 18 is fixedly installed at equal distances and in annular arrangement at the top of the clamping ring 13 and the top of the annular groove 17. The bottom surface of the protective washer is lower than the bottom surface of the punch head 16. By using the above-mentioned clamping assembly, when the entire upper die 12 is pressed down, the clamping ring 13 can contact the workpiece before the punch head 16, hold the workpiece, and ensure that the workpiece is in a stable state.

[0039] Working principle: During operation, the die handle 10 is connected to the hydraulic cylinder, and the workpiece is placed on the lower die 3. The hydraulic cylinder applies pressure to lower the height of the top seat 9, pad 11, upper die 12, and punch head 16. At this time, the clamping ring 13 in the clamping assembly will press against the workpiece to ensure its stability. As pressure continues to be applied, the top surface of the lower die 3 will be flush with the top surface of the die base 2, and the clamping ring 13 will enter the annular groove 17. At this time, the punch head 16 will enter the punching groove 15 to facilitate punching the workpiece, while the punching waste will pass through the punching groove. 15 falls into the waste discharge trough 14. During this process, the meshing action of the first rack plate 506, the toothed column 504 and the second rack plate 505 in the waste discharge assembly 5 drives the second rack plate 505 and the pusher seat 502 to move, thereby pushing the waste material out of the waste discharge trough 14, so as to facilitate the discharge of the punching waste material from the entire mold. After the hydraulic cylinder no longer applies force, the reset action of the third spring 20 in the support reset assembly and the reset action of the first spring 19 in the floating assembly drive the entire punching mold to reset, so as to facilitate the next punching operation.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
