Description

Technical Field

[0001] This application relates to the field of die technology, and particularly to a multi-station die for preventing part jumping. Background Art

[0002] During automobile production, many parts are processed and produced through a multi-station die, which is a die that causes plastic deformation through stamping and plays an important role in the processing of workpieces. Therefore, people's requirements for multi-station dies are getting higher and higher.

[0003] A multi-station die mentioned in an existing Chinese patent (authorized announcement number: CN211915212U) includes a multi-station die main body. A base is provided on the lower outer surface of the multi-station die main body. Cleaning mechanisms are fixedly installed on both outer surfaces of the base. A pre-grinding mechanism is provided on the front outer surface of the base. A stamping groove is provided on the inner surface of the middle part of the multi-station die main body. A connecting rod is provided on the upper outer surface of the multi-station die main body. An upper die is fixedly installed on the upper outer surface of the connecting rod. A stamping part is fixedly installed on the lower outer surface of the upper die. The multi-station die of the present utility model is provided with a cleaning mechanism and a pre-grinding mechanism, which can facilitate the cleaning of waste chips in the die, prevent the accumulation of waste chips and affect the quality of the next processing, and is beneficial for people to use. It can also pre-grind the workpieces to be processed, ensure the quality of workpiece stamping, and is beneficial for people to use, bringing a better application prospect.

[0004] When the multi-station die is in use, it is used for the processing and production of automobile parts. The raw materials of the parts to be processed are stamped through the multi-station die to facilitate the processing and production of the part raw materials. During stamping processing, the upper die and the lower die are prone to wear under long-term stamping and need to be replaced in time. The upper and lower dies of the above device are fixed by welding or bolts. When replacing, the staff needs to turn multiple bolts for disassembly and installation, which is rather inconvenient, time-consuming and laborious, and thus easily affects the stamping of the die. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that when the die is fixed by welding or bolts, the staff needs to turn multiple bolts for disassembly and installation during replacement, which is rather inconvenient and thus easily affects the stamping of the die. This application provides a multi-station die for preventing part jumping.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0007] A multi-station mold for preventing part jumping, including a cabinet body. On one side of the cabinet body, a support frame is fixed. At the lower end of the support frame, two symmetric hydraulic telescopic rods are fixed. The telescopic ends of the hydraulic telescopic rods are fixed with an upper mold. A lower mold is installed on the cabinet body. The lower mold corresponds to the upper mold. One end of the cabinet body is fixed with a limiting plate. A motor is fixed on the side of the limiting plate. At the lower end of the upper mold, two symmetric stamping parts are arranged. At the position corresponding to the stamping parts on the lower mold, an adapted stamping groove is opened. A limiting mechanism is arranged between the limiting plate and the support frame.

[0008] By adopting the above technical solution, when it is necessary to replace the lower mold and the stamping parts, start the motor. Through the limiting mechanism, it is convenient for the staff to replace the mold, improve the replacement efficiency, and reduce the impact on mold stamping.

[0009] Furthermore, the limiting mechanism includes a bidirectional screw fixed to the output end of the motor. The output end of the motor penetrates the limiting plate. Two symmetric fixing plates are threadedly connected to the bidirectional screw. Two symmetric abutting plates are fixed on the fixing plates. The abutting plates are in contact with the side of the lower mold. A limiting component is arranged between the fixing plate and the cabinet body.

[0010] By adopting the above technical solution, when the motor rotates, it drives the bidirectional screw to rotate. The bidirectional screw drives the fixing plates to move relatively away from each other, so that the abutting plates move away from the lower mold, releasing the restriction on the lower mold and facilitating replacement.

[0011] Furthermore, the limiting component includes a limiting column fixed to the limiting plate. The limiting column slidably penetrates the fixing plate. A connecting plate is fixed to one end of the cabinet body away from the limiting plate. The connecting plate is fixedly connected to the limiting column. The bidirectional screw is rotatably connected to the connecting plate. A limiting part is arranged between the stamping part and the upper mold.

[0012] By adopting the above technical solution, the fixing plate slides on the limiting column to limit the fixing plate and stops moving to a suitable distance.

[0013] Furthermore, the limiting part includes a support plate fixed to the upper end of the stamping part. A limiting groove is opened on the upper mold. The support plate is located in the limiting groove. A fixing column is slidably arranged in the upper mold. One end of the fixing column is fixed with a first spring. The end of the first spring away from the fixing column is fixedly connected to the upper mold. A fixing hole is opened on the support plate. The fixing column is located in the fixing hole. A handle is fixed on the fixing column. The handle slidably penetrates the upper mold.

[0014] By adopting the above technical solution, pulling the handle drives the fixing column to move, compressing the first spring, so that the fixing column moves out of the fixing hole, and then removing the stamping part and replacing it with a new one, which is convenient for replacement.

[0015] Further, the fixed plate and the abutting plate are metal rough surfaces.

[0016] By adopting the above technical solution, the fixed plate and the abutting plate are metal rough surfaces, which increases the fixing effect.

[0017] Further, four symmetric dampers are fixed on the lower die, four symmetric fixing grooves are formed on the lower die, the dampers are located in the fixing grooves, and support grooves are formed at the positions of the dampers corresponding to the upper die.

[0018] By adopting the above technical solution, the upper die presses the damper, the damper expands and contracts, and enters the fixing groove and the support groove, which is convenient for damping the die and improving the service life of the die.

[0019] Further, four symmetric second springs are fixed on the lower die, one end of the second spring far from the lower die is fixedly connected with the damper, and four symmetric limiting blocks are fixed on the lower die, and the limiting blocks correspond to the stamping grooves.

[0020] By adopting the above technical solution, the second spring expands and contracts, damps the lower die and the upper die, and increases the stability of stamping.

[0021] Further, four symmetric limiting rods are fixed at the lower end of the support frame, and the limiting rods slide through the upper die.

[0022] By adopting the above technical solution, the upper die slides on the limiting rods, improving the stability of the upper die and facilitating stamping.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When the die needs to be replaced, the hydraulic telescopic rod is closed, the motor is started, when the motor rotates, it drives the bidirectional screw to rotate, the bidirectional screw drives the fixed plate to move relatively away, so that the abutting plate moves away from the lower die, releasing the restriction on the lower die. At the same time, the fixed plate slides on the limiting column to limit the fixed plate, stops moving to a suitable distance, removes the lower die and replaces it with a new one, then starts the motor, the motor drives the fixed plate to move relatively closer, so that the fixed plate and the abutting plate restrict and fix the lower die. Through the limiting mechanism, it is convenient for the staff to replace the die, improving the replacement efficiency and reducing the impact on die stamping.

[0025] 2. When using a multi-station mold, the upper mold presses the damper, and the damper expands and contracts, causing the second spring to expand and contract, damping the lower mold and the upper mold, increasing the stability of stamping, extending the service life of the mold, reducing the bounce of elastic parts. The raw material of the part is restricted by the limiting block, reducing the bounce of elastic parts. The upper mold slides on the limiting rod, increasing the stability of stamping, extending the service life of the mold, reducing the bounce of elastic parts, improving the stability of the upper mold, and facilitating stamping.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will further elaborate on this application Figures 1-4 in further detail with reference to the accompanying drawings.

[0033] The embodiment of this application discloses a multi-station mold for preventing part bounce.

[0034] Referring to Figures 1-3 , a multi-station mold for preventing part bounce includes a cabinet 1. One side of the cabinet 1 is fixedly provided with a support frame 2. Two symmetric hydraulic telescopic rods 4 are fixedly provided at the lower end of the support frame 2. The telescopic end of the hydraulic telescopic rod 4 is fixedly provided with an upper mold 3. A lower mold 5 is installed on the cabinet 1. The lower mold 5 corresponds to the upper mold 3. A limiting plate 6 is fixedly provided at one end of the cabinet 1. A motor 7 is fixedly provided on the side of the limiting plate 6. Two symmetric stamping parts 13 are provided at the lower end of the upper mold 3. A matching stamping groove is provided at the position of the lower mold 5 corresponding to the stamping parts 13. A limiting mechanism is provided between the limiting plate 6 and the support frame 2.

[0035] When the multi-station mold is in use, the staff puts the raw material of the part to be processed on the lower mold 5, corresponding to the stamping part 13, and then starts the extension and retraction of the hydraulic telescopic rod 4. The hydraulic extension drives the upper mold 3 to move, so that the stamping part 13 stamps the raw material of the part, and cooperates with the stamping groove of the lower mold 5 to facilitate the stamping of the raw material of the part. When the lower mold 5 and the stamping part 13 need to be replaced, the motor 7 is started. Through the limiting mechanism, it is convenient for the staff to replace the mold, improve the replacement efficiency, and reduce the impact on the mold stamping.

[0036] Reference Figures 2-4 The limiting mechanism includes a bidirectional screw 8 fixed to the output end of the motor 7, the output end of the motor 7 passes through the limiting plate 6, two symmetrical fixing plates 11 are threadedly connected to the bidirectional screw 8, two symmetrical abutment plates 12 are fixed to the fixing plate 11, the abutment plates 12 are in contact with the side of the lower mold 5, and a limiting component is arranged between the fixing plate 11 and the cabinet 1. The limiting component includes a limiting column 9 fixed to the limiting plate 6, the limiting column 9 slides through the fixing plate 11, a connecting plate 10 is fixed to the end of the cabinet 1 away from the limiting plate 6, the connecting plate 10 is fixedly connected to the limiting column 9, the bidirectional screw 8 is rotatably connected to the connecting plate 10, and a limiting member is arranged between the stamping part 13 and the upper mold 3. The limiting part includes a support plate 14 fixed to the upper end of the stamping part 13, a limiting groove is provided on the upper mold 3, the support plate 14 is located in the limiting groove, a fixing column 16 is slidably provided in the upper mold 3, a spring 15 is fixed to one end of the fixing column 16, and the end of the spring 15 away from the fixing column 16 is fixedly connected to the upper mold 3, a fixing hole is provided on the support plate 14, the fixing column 16 is located in the fixing hole, a handle 17 is fixed to the fixing column 16, and the handle 17 slides through the upper mold 3. The fixing plate 11 and the contact plate 12 are rough metal surfaces.

[0037] When the multi-station mold is in use, the hydraulic telescopic rod 4 is closed, and the motor 7 is started. When the motor 7 rotates, the bidirectional screw 8 is driven to rotate, and the bidirectional screw 8 drives the fixed plate 11 to move relatively away, so that the contact plate 12 moves away from the lower mold 5, and the restriction on the lower mold 5 is released. At the same time, the fixed plate 11 slides on the limiting column 9 to restrict the fixed plate 11, moves to a suitable distance and stops, removes the lower mold 5 and replaces it with a new one, and then starts the motor 7. The motor 7 drives the fixed plate 11 to move relatively close, so that the fixed plate 11 and the contact plate 12 restrict the lower mold 5. The fixing plate 11 and the contact plate 12 are rough metal surfaces to increase the fixing effect, and then the handle 17 is pulled to drive the fixing column 16 to move, and the spring 15 is compressed to make the fixing column 16 move out of the fixing hole, and then the stamping part 13 is removed and replaced with a new one. The elasticity of the spring 15 makes the fixing column 16 enter the fixing hole to restrict the support plate 14, and restrict the stamping part 13, which is convenient for the staff to replace the mold. Through the limiting mechanism, it is convenient for the staff to replace the mold, improve the replacement efficiency, and reduce the impact on the mold stamping.

[0038] Reference Figure 3 and Figure 4 Four symmetrical dampers 18 are fixed on the lower mold 5, and four symmetrical fixing grooves are opened on the lower mold 5. The dampers 18 are located in the fixing grooves, and the dampers 18 are opened at positions corresponding to the upper mold 3. Four symmetrical springs 19 are fixed on the lower mold 5, and one end of the springs 19 away from the lower mold 5 is fixedly connected to the dampers 18. The lower mold 5 is fixed with four symmetrical limiting blocks 20, and the limiting blocks 20 correspond to the stamping grooves. Four symmetrical limiting rods 21 are fixed at the lower end of the support frame 2, and the limiting rods 21 slide through the upper mold 3.

[0039] When the multi-station mold is in use, the upper mold 3 squeezes the damper 18, and the damper 18 expands and contracts, causing the spring 2 19 to expand and contract, thereby reducing the shock of the lower mold 5 and the upper mold 3, increasing the stability of stamping, improving the service life of the mold, and reducing the vibration of elastic parts. The part material is restricted by the limiting block 20 to reduce the vibration of elastic parts. The upper mold 3 slides on the limiting rod 21 to improve the stability of the upper mold 3 and facilitate stamping.

[0040] The implementation principle of a multi-station mold for preventing parts from jumping in this embodiment is as follows: when the multi-station mold is used, the staff puts the parts raw materials to be processed on the lower mold 5, corresponding to the stamping part 13, and then starts the hydraulic telescopic rod 4 to extend and retract, and the hydraulic telescopic rod 4 drives the upper mold 3 to move, so that the stamping part 13 stamps the parts raw materials, and cooperates with the stamping groove of the lower mold 5 to facilitate stamping of the parts raw materials;

[0041] During stamping, the upper die 3 squeezes the damper 18, and the damper 18 expands and contracts, so that the spring 2 19 expands and contracts, and the lower die 5 and the upper die 3 are damped, thereby increasing the stability of stamping, improving the service life of the die, and reducing the vibration of the elastic parts. The limiting block 20 is used to limit the part material, and the vibration of the elastic parts is reduced. The upper die 3 slides on the limiting rod 21, and the stability of the upper die 3 is improved;

[0042] When it is necessary to replace the mold, the hydraulic telescopic rod 4 is closed and the motor 7 is started. When the motor 7 rotates, the bidirectional screw 8 is driven to rotate. The bidirectional screw 8 drives the fixed plate 11 to move relatively away, so that the contact plate 12 moves away from the lower mold 5, and the restriction on the lower mold 5 is released. At the same time, the fixed plate 11 slides on the limiting column 9 to restrict the fixed plate 11, moves to a suitable distance and stops, and the lower mold 5 is removed and replaced with a new one. The motor 7 is started again, and the motor 7 drives the fixed plate 11 to move relatively close, so that the fixed plate 11 and the contact plate 12 restrict and fix the lower mold 5. The fixed plate 11 and the contact plate 12 are rough metal surfaces to increase the fixing effect, and then the handle 17 is pulled to drive the fixed column 16 to move, and the spring 15 is compressed, so that the fixed column 16 moves out of the fixing hole, and the stamping part 13 is removed and replaced with a new one. The elasticity of the spring 15 makes the fixed column 16 enter the fixed hole to restrict the support plate 14, and restrict the stamping part 13, which is convenient for the staff to replace the mold.
