Description

Technical Field

[0001] The utility model relates to the technical field of stamping die fixing, in particular to a stamping die used for producing a spring disc of an automobile shock absorber. Background Art

[0002] The stamping die for automobile shock absorber spring disc production is a die specially used for manufacturing automobile shock absorber spring disc. This die uses pressure to process metal sheets or other materials into spring discs with specific shapes and sizes through a stamping process. The stamping die usually consists of two parts, the upper die part includes a punch or a punch, and the lower die part includes a die or a die seat. During the stamping process, the upper die and the lower die are brought close to each other by the pressure of the stamping machine, so that the metal sheet undergoes plastic deformation in the die cavity, thereby obtaining the desired spring disc shape.

[0003] According to the Chinese patent CN202220446862.7, in this application, by setting up a waste automatic ejection structure, by using the spring telescopic rod, the push plate, the foolproof rubber block, and the foolproof fitting groove in coordination, the waste in the punching slot after punching can be automatically ejected, saving the time of manual material removal and improving work efficiency;

[0004] Although the automatic waste ejection structure in the application can effectively deal with the problem of waste accumulation, when in use, due to the lack of flexibility in height adjustment of the material fixing structure, it cannot adapt to the stamping processing requirements of metal plates of different thicknesses. If the stamping height is not set properly, excessive stamping may cause the mold to be overstressed and damaged, which not only increases the maintenance cost, but also may affect the production schedule. For this reason, we propose a stamping die for the production of automobile shock absorber spring discs. Utility Model Content

[0019] 1. The stamping die for producing automobile shock absorber spring discs has an adjustment structure that, when in operation, operates the threaded rod to move the ejector pin. The movement of the ejector pin pushes the adjustment column to move upward or downward in the first placement slot. Due to the existence of the limiting column, the movement of the adjustment column drives the limiting plate to move together, thereby changing the distance between the auxiliary block and the limiting plate. Through the design of the adjustment structure, the die can be adjusted accordingly according to the different thicknesses of the metal plates to be processed.

[0027] An adjustment structure disposed on the top of the punching machine worktable 2, which is used to make corresponding adjustments according to the thickness of the metal plate 12 to be processed;

[0028] A fixed structure is arranged on the top of the punching machine workbench 2, which is used to fix the adjustment structure. After the adjustment and fixing are completed, the metal plate 12 to be processed is placed between the auxiliary block 11 and the limiting plate 14, and the cylinder 5 is started to drive the stamping upper die 6 to move downward, and work together with the stamping lower die 8 to complete the stamping operation on the metal plate 12 to be processed. After the stamping is completed, the cylinder 5 drives the stamping upper die 6 to rise, takes out the processed metal plate, and performs the next round of operation.

[0029] Furthermore, four groups of movable rods 7 are fixedly connected to the top of the punching machine worktable 2 , and a punching lower die 8 is fixedly connected between the four groups of movable rods 7 and at positions corresponding to the top of the punching machine worktable 2 .

[0030] Furthermore, a fixing plate 9 is fixedly connected to the top of the four groups of movable rods 7 , and a stamping groove 10 is formed on the top of the fixing plate 9 .

[0031] Furthermore, two groups of auxiliary blocks 11 are fixedly connected to the top of the fixed plate 9 and the corresponding position of the stamping groove 10. The first placement groove 15 is opened inside the two groups of auxiliary blocks 11, and the second placement groove 16 is opened at the top of the first placement groove 15 and the corresponding position inside the auxiliary block 11.

[0032] Furthermore, the adjustment structure includes an adjustment column 13, a limiting column 17, a spring 18 and a wedge-shaped groove 19. The bottom of the inner wall of the first placement groove 15 is fixedly connected with a spring 18, and the top of the spring 18 is fixedly connected with the adjustment column 13. The outer side of the adjustment column 13 is movably connected to the inner wall of the first placement groove 15, and the outer side of the adjustment column 13 is movably connected to the corresponding position of the inner wall of the second placement groove 16 with a limiting column 17, and the outer side of the limiting column 17 is fixedly connected to the inner wall of the second placement groove 16. A wedge-shaped groove 19 is provided on one side of the adjustment column 13. The movement of the top pin 21 will push the adjustment column 13 to move upward or downward in the first placement groove 15. The spring 18 plays a role of buffering and resetting, ensuring that the adjustment column 13 can return to the initial position when not subject to external force. The top pin 21 can be inserted into the wedge-shaped groove 19 of the adjustment column 13, thereby locking the position of the adjustment column 13.

[0033] Furthermore, the outer side of the limiting column 17 is movably connected to a limiting plate 14, the top of the limiting plate 14 is fixedly connected to the outer side of the adjusting column 13, and the bottom of the limiting plate 14 is movably connected to the outer side of the metal plate 12 to be processed.

[0035] Working principle:

[0036] When it is necessary to adjust the distance between the auxiliary block 11 and the limiting plate 14 to adapt to the different thicknesses of the metal plates 12 to be processed, the threaded rod 22 can be operated to move the top pin 21. The movement of the top pin 21 will push the adjusting column 13 to move upward or downward in the first placement groove 15. Due to the existence of the limiting column 17, the movement of the adjusting column 13 will drive the limiting plate 14 to move together, thereby changing the distance between the auxiliary block 11 and the limiting plate 14. The spring 18 plays a buffering and resetting role to ensure that the adjusting column 13 can return to the initial position when not subject to external force. After adjusting to the appropriate distance, the adjusting structure needs to be fixed to prevent movement during the stamping process. By rotating By turning the threaded rod 22, the ejector pin 21 can be inserted into the wedge-shaped groove 19 of the adjusting column 13, thereby locking the position of the adjusting column 13; after the adjustment and fixation are completed, the metal plate 12 to be processed is placed between the auxiliary block 11 and the limiting plate 14, and the cylinder 5 is started to drive the stamping upper die 6 to move downward, and work together with the stamping lower die 8 to complete the stamping operation of the metal plate 12 to be processed. After the stamping is completed, the cylinder 5 drives the stamping upper die 6 to rise, takes out the processed metal plate, and performs the next round of operation; the entire system realizes the stamping processing of metal plates of different thicknesses through the cooperation of the adjusting structure and the fixing structure, thereby improving the adaptability and working efficiency of the equipment.
