Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts trimming technology, specifically to an automotive parts stamping forming device. Background Technology
[0002] Existing patent CN218925838U provides a stamping forming device for automotive parts sheet metal. It works by "rotating a lead screw, which drives two moving blocks to move towards each other. The moving blocks, through a moving rod, drive a moving plate, which in turn drives a first locking pin. The first locking pin then separates from the forming seat, thus releasing the fixing of the forming seat and lifting it to separate it from the positioning block, thereby completing the disassembly of the forming seat. After the old forming seat is removed, a new forming seat of different types can be installed." While the lead screw can fix the forming seat, its operation requires rotating the lead screw, resulting in a slow adjustment speed and difficulty in quickly disassembling the forming seat. Furthermore, it lacks a buffer structure during stamping, and frequent stamping may damage the forming seat. Therefore, this paper proposes a stamping forming device for automotive parts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a new technical solution: a new type of automotive parts stamping forming device, including a base 1, an L-shaped plate 2 fixedly installed on the upper surface of the base 1, a stamper 3 fixedly installed on the upper surface of the horizontal plate of the L-shaped plate 2, a push rod of the stamper 3 passing through the lower surface of the L-shaped plate 2, and a stamping block 4 fixedly installed at the lower end of the push rod of the stamper 3.
[0025] The disassembly and assembly mechanism is located on the upper surface of the base 1. The disassembly and assembly mechanism is used to replace different molding molds. The disassembly and assembly mechanism includes a molding seat 5, which is located on the upper surface of the base 1.
[0026] A buffer mechanism is located on the upper surface of the base 1. The buffer mechanism is used to buffer the stamping of automotive parts. The buffer mechanism includes two dampers 6, both of which are fixedly installed on the upper surface of the base 1.
[0027] Furthermore, the disassembly and assembly mechanism also includes a fixing post 9 and two slots 10. The fixing post 9 is fixedly installed on the upper surface of the base 1, and the two slots 10 are respectively opened on the outer surface of the fixing post 9.
[0028] Furthermore, a slot 11 is provided on the lower surface of the molding base 5, and two spring grooves 12 are provided on the inner wall of the slot 11. Sliding holes 13 are provided on both sides of the molding base 5, and both sliding holes 13 are connected to the spring grooves 12.
[0029] Furthermore, the disassembly and assembly mechanism also includes two fixing rods 14 and two pull rings 15. The two fixing rods 14 are slidably sleeved in the two sliding holes 13, and two pull rings 15 are fixedly installed at opposite ends of the two fixing rods 14.
[0030] Furthermore, the disassembly and assembly mechanism also includes two locking blocks 16 and two second springs 17. The two locking blocks 16 are fixedly installed on the opposite ends of the two fixing rods 14, and the lower surfaces of the two locking blocks 16 are both inclined. The opposite sides of the two locking blocks 16 are fixedly installed with the second springs 17, and the opposite ends of the two second springs 17 are respectively fixedly installed on the inner walls of the two spring grooves 12.
[0031] Furthermore, the buffer mechanism also includes two dampers 6, two first springs 7, and two piston rods 8. The two dampers 6 are fixedly mounted on the upper surface of the base 1, the two first springs 7 are fixedly mounted on the upper surface of the two dampers 6, and the two piston rods 8 are respectively fixedly mounted on the upper ends of the two first springs 7, with the two piston rods slidably sleeved on the inner surfaces of the two dampers 6. When this component stamping device is in use, the material is placed in the forming seat 5. Then, by activating the stamper 3, the stamping block 4 fixedly mounted at the lower end of the push rod of the stamper 3 moves downward, completing the stamping process. During the falling... Simultaneously, the piston rod 8 of the stamping block applies pressure, causing it to slide downwards in the damper 6. While sliding, the piston rod 8 applies pressure to the first spring 7 fixedly mounted on the lower surface, causing it to contract. The elastic potential energy of the first spring 7 forms a buffer. By inserting the slot opened on the lower surface of the forming seat 5 into the outer surface of the fixing post 9, the inclined surface of the locking block 16 set in the slot impacts the inclined surface of the fixing post 9. At this time, the fixing post 9 applies opposing thrusts to the two locking blocks 16, causing them to move in opposite directions. Simultaneously, the two locking blocks 16 apply pressure to the second spring 17 fixedly mounted on opposite sides. This causes the block to contract. The insertion continues, and the two locking blocks 16 are now positioned in the two slots 10 on the outer surface of the fixing post. The locking blocks 16 are no longer under force, and the second springs 17 are also no longer under force. The two second springs 17 expand and exert a pushing force on the locking blocks 16 fixed at the opposite ends, causing them to move towards the opposite ends and engage with the slots 10 for fixation. Installation is now complete. To disassemble, pull the ring 15. The ring 15 moves the fixing rod 14 fixed on the right surface to the left, and the fixing rod 14 moves the locking block 16 at the right end to the right. At this point, the locking blocks 16... The forming seat 5 can be disassembled after being released from the slot 10. This part stamping forming device can install the forming seat 5 by snap-fitting, and disassembly is convenient and fast, allowing for quick replacement of the forming seat 5. After replacement, different shapes can be stamped according to different forming seats 5, improving production diversity. Furthermore, this part stamping forming device can use the damper 6 and the first spring 7 to buffer the press 3 when it falls, dispersing the pressure during the fall and making it difficult to apply excessive pressure to the forming seat 5, causing breakage and extending the service life of the machine.
[0032] Working principle: When using this part stamping forming device, the material is placed in the forming seat 5. Then, by activating the stamper 3, the stamping block 4, which is fixedly installed at the lower end of the push rod of the stamper 3, moves downward to complete the stamping. At the same time as it falls, the piston rod 8 of the stamping block applies pressure, causing it to slide downward in the damper 6. Simultaneously, the piston rod 8 applies pressure to the first spring 7 fixedly installed on the lower surface, causing it to contract. The elastic potential energy of the first spring 7 forms a buffer. By inserting the slot opened on the lower surface of the forming seat 5 into the outer surface of the fixed post 9, the inclined surface of the locking block 16 set in the slot hits the inclined surface of the fixed post 9. At this time, the fixed post 9 applies opposing thrusts to the two locking blocks 16, causing them to move in opposite directions. Simultaneously, the two locking blocks 16 apply pressure to the second spring 17 fixedly installed on opposite sides, causing it to contract. At this time, the insertion continues. The two locking blocks 16 are located in the two slots 10 opened on the outer surface of the fixing post. At this time, the locking blocks 16 are no longer under force, and the second spring 17 is no longer under force. At this time, the two second springs 17 expand and apply a pushing force to the locking blocks 16 fixedly installed on opposite ends, causing them to move towards the opposite ends and engage with the slots 10 for fixation. The installation is now complete. When disassembly is required, by pulling the pull ring 15, the pull ring 15 drives the fixing rod 14 fixedly installed on the right surface to move to the left. The fixing rod 14 drives the locking block 16 on the right end to move to the right. At this time, the locking block 16 disengages from the slot 10, and the molding seat 5 can be disassembled.
