Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a stamping die for automobile fasteners, which solves the problem that the traditional stamping die does not have the function of wear protection, and the notch of the die often rubs against the material under pressure. After processing, the molding accuracy is reduced, the entire mold needs to be replaced, and the practical life of the mold is low.

Embodiment 1

[0035] Such as Figure 1-4 As shown, the present invention provides a technical solution: a stamping die for automobile fasteners, comprising a stamping upper plate 1 and a stamping lower plate 2, a stamping die 3 is arranged at the middle of the top of the stamping lower plate 2, and the stamping die 3. Limiting holes 4 are evenly arranged around the top. The middle position of the bottom of the stamping upper plate 1 is fixedly connected with a stamping punch 5. The stamping punch 5 is set correspondingly to the stamping die 3. The bottom of the stamping upper plate 1 is located at the stamping punch 5. The outer side is fixedly connected with a transmission ring plate 6, the bottom end of the stamping die 3 is fixedly connected with a die bottom groove 7, and the middle position of the die bottom groove 7 is provided with a die crimping mechanism 8, and the surface of the top of the die bottom groove 7 is A storage adjustment mechanism 9 is provided;

[0036] The top of th...

Embodiment 2

[0039] Such as Figure 5-6 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a stamping die for automobile fasteners, the die crimping mechanism 8 includes an air pump groove 81, and the air pump groove 81 is arranged inside the stamping die 3 In the middle position of the air pump tank 81 , the top end of the air pump groove 81 is connected with a sealing insertion rod 82 , and the top of the sealing insertion rod 82 is fixedly connected with a sealing crimping plate 83 . The air pressure and the stamping driving force form a stable clamping force, which realizes pre-positioning and stable clamping before material stamping.

[0040] The air pressure top plate 85 is fixedly connected with the bottom end of the sealing insert rod 82 positioned at the inside of the air pump groove 81, and the air pressure top plate 85 is evenly fixedly connected with an adjusting blade 86 around the inner side. Improve the cleanliness of the mold, furthe...

Embodiment 3

[0044] Such as Figure 7 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a stamping die for automobile fasteners, the storage adjustment mechanism 9 includes a storage pad groove 91, and the inside of the storage pad groove 91 is connected with the sealing pressure The connecting plate 83 corresponds, and the swing pusher assembly 87 is arranged correspondingly to the outer sides around the receiving pad groove 91 . The completeness of the stamping shape is guaranteed, and the sealing protrusion 872 blocks the ventilation hole 84 to ensure that the air pump groove 81 is always under high pressure.

[0045] A mating insert 92 is evenly and fixedly connected around the outside of the storage pad groove 91 , and a resistance-increasing wave block 93 is fixedly connected to the top surface of the mating insert 92 . When the scraper 871 moves and intersects with the insert block 92, the impurities at the bottom can be s...

Abstract

The invention discloses an automobile fastener stamping die, and relates to the technical field of stamping dies. The die comprises an upper stamping plate and a lower stamping plate, a stamping female die is arranged in the middle of the top of the lower stamping plate, limiting holes are evenly formed at the periphery of the top of the stamping female die, and a stamping male die is fixedly connected to the middle of the bottom of the upper stamping plate; and the stamping male die and the stamping female die are correspondingly arranged, a transmission ring plate is fixedly connected to the position, located at the outer side of the stamping male die, of the bottom of the stamping upper plate, a female die bottom groove is fixedly connected to the bottom end of the interior of the stamping female die, and a female die pressing connection mechanism is arranged in the middle of the female die bottom groove. A storage adjusting mechanism is arranged on the surface of the top of the female die bottom groove. According to the automobile fastener stamping die, the effects of pre-positioning and stable clamping before material stamping are achieved, and the forming precision is improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for automobile fasteners. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in cold stamping processing, called cold stamping die. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] As the Chinese invention publication number is: a kind of stamping die for automobile fasteners of CN110884202A. The automotive fastener stamping die comprises a lower mold base, the upper surface of the lower mold base is fixedly connected to the bottom end of the limiting column, and the end of the limiting column away from the lower mold base is movably connected to the upper mold base, The upper surface of the upper mold base is fixedly connected with a l...
