Description

Technical Field

[0001] This invention relates to the field of progressive die processing technology, and in particular to a workstation layout device for progressive die processing. Background Technology

[0002] A progressive die is a cold stamping die in which a press uses strip-shaped raw material to simultaneously complete multiple stamping processes at several different stations on a single die during a single stamping stroke. Each time the die completes a stamping stroke, the strip material moves a fixed distance until the product is finished. A progressive die can complete multiple processes such as blanking, bending, forming, and deep drawing. However, with current transfer dies, when the spacing and position of the transfer stations need to be adjusted, the traditional method is to manually move the stations using hand tools and then reinstall them. This method is not only time-consuming and labor-intensive, but also prone to misalignment and displacement during adjustment, reducing stability.

[0003] A search revealed a continuous die arrangement structure for a backlit rubber-coated iron hardware part, as disclosed in Chinese Patent Publication No. CN213763691U. This structure includes an upper die assembly, a stop plate, a stripper plate, and a lower die assembly. The stop plate is positioned between the upper die assembly and the stripper plate, and the lower die assembly is positioned below the stripper plate. The stripper plate is composed of a first segmented plate, a second segmented plate, and a third segmented plate arranged in parallel. Template segment connecting inserts are provided between the first segmented plate and the second segmented plate, and between the second segmented plate and the third segmented plate.

[0004] The cited patent documents also have the same problem, which use manual hand disassembly tools to move the workstation and then reinstall it for adjustment. However, this method is not only time-consuming and labor-intensive, but also prone to misalignment and displacement during adjustment, which reduces stability. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a workstation layout device for progressive die processing, which can effectively solve the aforementioned problems.

[0006] To achieve the above requirements, the technical solution adopted by the present invention to solve its technical problem is as follows:

[0007] A workstation layout device for continuous die processing is provided, comprising a first workstation section and a second workstation section. The first workstation section includes a first station plate, and the second workstation section includes a second station plate. Continuous transfer dies are arranged on the top surfaces of both the first and second station plates. A workstation layout adjustment assembly is provided between the first and second station plates. Centripetal clamping and positioning assemblies are provided on both sides of the first station plate. The workstation layout adjustment assembly includes L-shaped fixing plates welded to the outer walls of both sides of the first station plate, connecting plates welded to the outer walls of the opposite ends of the second station plate, and hydraulic cylinders installed on the outer walls of the L-shaped fixing plates. The piston rod of the hydraulic cylinders passes through the L-shaped fixing plates and is fixedly connected to the connecting plates. A pressing positioning plate for pressing and positioning the second station plate is installed on the top surface of the free end of each L-shaped fixing plate. The bottom surface of the pressing positioning plate slides in contact with the top surface of the second station plate.

[0008] In a preferred embodiment, two positioning extension rods are symmetrically welded to one side of the first workstation plate facing the second workstation plate, and the free ends of the two positioning extension rods extend and are inserted into the second workstation plate.

[0009] In this preferred embodiment, threaded holes are provided on the top surface of the pressing positioning plate and the top surface of the free end of the L fixing plate.

[0010] The pressure positioning plate is connected to the L fixing plate by locking bolts.

[0011] In this preferred embodiment, the bottom surface of the end of the pressing positioning plate away from the L fixed plate is embedded with a positioning ball. When the hydraulic cylinder pushes or pulls the second work station plate, the positioning ball makes rolling friction contact with the top surface of the second work station plate.

[0012] In a preferred embodiment of this scheme, a first mounting bracket is fixedly installed on the inner wall of one end of each L-fixed plate near the lower positioning plate, and a first clamping and positioning auxiliary wheel is rotatably installed in the first mounting bracket.

[0013] In this preferred embodiment, the first clamping and positioning auxiliary wheel and the outer wall of the second workstation plate engage in rolling clamping frictional contact.

[0014] In a preferred embodiment of this scheme, the centripetal clamping and positioning assembly includes L-positioning supports symmetrically arranged on both sides of the first workstation plate and two second clamping and positioning auxiliary wheels symmetrically arranged on opposite sides of the two L-positioning supports.

[0015] In this preferred embodiment, the two L-positioning supports are symmetrically welded with supporting ribs on opposite sides, and two second mounting brackets are installed on opposite sides of the two L-positioning supports.

[0016] The second clamping and positioning auxiliary wheel is rotatably mounted in the second mounting bracket.

[0017] In this preferred embodiment, the outer wall of the second clamping and positioning auxiliary wheel is wrapped with a rubber shock-absorbing buffer washer, and the rubber shock-absorbing buffer washer elastically abuts against the outer wall of the first workstation plate.

[0018] In this preferred embodiment, the outer wall of the first workstation plate facing away from the second workstation plate is symmetrically welded with supporting and limiting blocks.

[0019] The beneficial effects of this invention are as follows: When the workstation layout device for continuous die processing needs to adjust the layout spacing between the first workstation and the second workstation, the hydraulic cylinder is activated. The piston rod of the hydraulic cylinder extends and pushes the connecting plate, which in turn pushes the second workstation plate to move successively. This replaces the traditional method of manually disassembling and adjusting the spacing and position between different workstations, improving the layout adjustment efficiency and stability, and preventing misalignment or deviation of different workstations during the adjustment process. When the hydraulic cylinder is running, it has a recoil force. With the cooperation of the L-positioning support and the second clamping positioning auxiliary wheel, the first workstation plate can be stably and centripetally clamped, preventing the recoil force from pushing the first workstation plate to move. The rubber shock-absorbing buffer gasket can also provide shock absorption for the first workstation plate, further improving stability. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0031] The preferred embodiment of the present invention is a workstation layout device for progressive die processing, such as... Figures 1 to 3 The diagram shows a first workstation 1 and a second workstation 2. The first workstation 1 includes a first workstation plate 3, and the second workstation 2 includes a second workstation plate 4. Supporting and limiting blocks 6 are symmetrically welded to the outer wall of the side of the first workstation plate 3 facing away from the second workstation plate 4. The supporting and limiting blocks 6 are installed to the processing machine table by bolts.

[0032] In this embodiment, continuous transfer molds 5 are arranged on the top surfaces of the first workstation plate 3 and the second workstation plate 4. A workstation arrangement adjustment assembly 13 is provided between the first workstation plate 3 and the second workstation plate 4. The workstation arrangement adjustment assembly 13 includes L-fixed plates 8 welded to the outer walls of both sides of the first workstation plate 3, connecting plates 14 welded to the outer walls of the opposite ends of the second workstation plate 4, and a hydraulic cylinder 11 installed on the outer wall of the L-fixed plate 8. The piston rod 15 of the hydraulic cylinder 11 passes through the L-fixed plate 8 and is fixedly connected to the connecting plates 14.

[0033] Specifically, when it is necessary to adjust the spacing between the first workstation 1 and the second workstation 2, the hydraulic cylinder 11 is activated. The piston rod 15 of the hydraulic cylinder 11 extends and pushes the connecting plate 14. Under the action of the connecting plate 14, the second workstation plate 4 is moved in succession. This replaces the traditional method of manually disassembling and adjusting the spacing and position between different workstations, improves the efficiency and stability of the layout adjustment, and prevents different workstations from being misaligned or deviating from their positions during the adjustment process.

[0034] In this embodiment, a centripetal clamping and positioning assembly 12 is provided on both sides of the first workstation plate 3. The centripetal clamping and positioning assembly 12 includes L-positioning supports 7 symmetrically arranged on both sides of the first workstation plate 3 and two second clamping and positioning auxiliary wheels 22 symmetrically arranged on opposite sides of the two L-positioning supports 7. Supporting ribs 20 are symmetrically welded on opposite sides of the two L-positioning supports 7. Two second mounting brackets 21 are installed on opposite sides of the two L-positioning supports 7. The second clamping and positioning auxiliary wheels 22 are rotatably installed in the second mounting brackets 21. The outer ring of the second clamping and positioning auxiliary wheels 22 is wrapped with rubber shock-absorbing buffer washers. The rubber shock-absorbing buffer washers elastically abut against the outer wall of the first workstation plate 3.

[0035] Specifically, when the hydraulic cylinder 11 is running, the hydraulic cylinder 11 has a recoil force. With the cooperation of the L-positioning support 7 and the second clamping positioning auxiliary wheel 22, the first workstation plate 3 can be stably and centripetally clamped to prevent the recoil force from pushing the first workstation plate 3 to move. Under the action of the rubber shock-absorbing buffer washer, the first workstation plate 3 can be shock-absorbing and buffered, further improving stability.

[0036] In this embodiment, each L-fixed plate 8 has a pressing positioning plate 9 installed on the top surface of its free end to press down and position the second workstation plate 4. The bottom surface of the pressing positioning plate 9 slides in contact with the top surface of the second workstation plate 4. The bottom surface of the pressing positioning plate 9 away from the L-fixed plate 8 has a rolling positioning ball 19 embedded in it. When the hydraulic cylinder 11 pushes and pulls the second workstation plate 4, the positioning ball 19 rolls and rubs against the top surface of the second workstation plate 4.

[0037] Specifically, when the second workstation plate 4 is linearly displaced, the pressing positioning plate 9 can press down and position the second workstation plate 4 to prevent it from shifting or deviating. Under the action of the positioning ball bearing 19, it can assist the smooth movement of the second workstation plate 4 and improve the displacement accuracy without affecting the movement of the second workstation plate 4.

[0038] In this embodiment, two positioning extension rods 10 are symmetrically welded to one side of the first workstation plate 3 facing the second workstation plate 4. The free ends of the two positioning extension rods 10 extend and are inserted into the second workstation plate 4. The positioning extension rods 10 position the movement of the second workstation plate 4.

[0039] In this embodiment, threaded holes are provided on the top surface of the pressure positioning plate 9 and the top surface of the free end of the L fixing plate 8. The pressure positioning plate 9 is connected to the L fixing plate 8 by locking bolts 18. The pressure positioning plate 9 is designed to be detachable, which improves the efficiency of replacement and maintenance.

[0040] Specifically, each L-fixed plate 8 has a first mounting bracket 16 fixedly installed on the inner wall of the end near the lower positioning plate 9. A first clamping and positioning auxiliary wheel 17 is rotatably installed in the first mounting bracket 16. The first clamping and positioning auxiliary wheel 17 and the outer wall of the second workstation plate 4 are in rolling clamping and frictional contact. The first clamping and positioning auxiliary wheel 17 positions the movement of the second workstation plate 4 and assists the horizontal displacement of the second workstation plate 4.

[0041] Working principle

[0042] When the spacing between the first workstation 1 and the second workstation 2 needs to be adjusted in this progressive die processing workstation layout device, the hydraulic cylinder 11 is activated. The piston rod 15 of the hydraulic cylinder 11 extends and pushes the connecting plate 14. Under the action of the connecting plate 14, the second workstation plate 4 moves successively. When the hydraulic cylinder 11 is running, the hydraulic cylinder 11 has a recoil force. With the cooperation of the L-positioning support 7 and the second clamping positioning auxiliary wheel 22, the first workstation plate 3 can be stably and centripetally clamped to prevent the recoil force from pushing the first workstation plate 3 to move. When the second workstation plate 4 moves linearly, the pressing positioning plate 9 can press down and position the second workstation plate 4 to prevent the second workstation plate 4 from shifting. Under the action of the positioning ball 19, the smooth movement of the second workstation plate 4 can be assisted, and the displacement accuracy can be improved without affecting the movement of the second workstation plate 4.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
