Problems solved by technology

At present, the forming process of automobile nut plate parts generally includes several processes such as stretching and punching. The specific steps are usually to place the automobile nut plate parts to be processed in the mold, stretch and punch one by one, and complete the cycle several times. Such an operation method is not only labor-intensive, but also inefficient, and the parts are easily deformed during the transmission process of each process, resulting in unstable parts, poor final product status, non-vertical nut cylinders, broken threads in the ribs, and scrapped The rate is high, and the maintenance workload of the mold is large

Embodiment

[0016] Such as figure 1 Shown, a kind of mold of automobile nut plate parts comprises a lower mold base 1 and an upper mold base 8, the lower mold base 1 is successively provided with a lower forming die 5 and a lower punching die 9, and the upper die base 8 is successively provided with There are upper die guide pillar 2, upper die guide pin 3, upper die positioning pin 4, upper forming punch 6 and upper punching punch 7.

[0017] The lower forming die 5 corresponds to the upper forming punch 6, and the number of the lower forming die 5 and the upper forming punch 6 can be set according to the actual number and diameter of nut plates. In this example, 6 groups are set, and the lower forming die 5 The aperture and the diameter of the upper forming punch 6 gradually decrease successively.

[0018] The lower punching die 9 corresponds to the upper punching die 7, and the number of the lower forming die 5 and the upper forming die 6 can be set according to the actual number and ...

Abstract

The invention relates to an automobile nut plate part die. The die comprises a lower die base (1) and an upper die base (8). The lower die base (1) is sequentially provided with a lower forming female die (5) and a lower piercing female die (9), and the upper die base (8) is sequentially provided with an upper die guide post (2), an upper die guide pin (3), an upper die locating pin (4), an upper forming male die (6) and an upper piercing male die (7). Compared with the prior art, the die disclosed by the invention has the advantages of low production cost, safety, reliability, high production efficiency and the like.

Description

technical field [0001] The invention relates to a mold for producing automobile parts, in particular to a mold for automobile nut plate parts. Background technique [0002] The car nut plate is used to fix the parts of the car together to ensure driving safety. At present, the forming process of automobile nut plate parts generally includes several processes such as stretching and punching. The specific steps are usually to place the automobile nut plate parts to be processed in the mold, stretch and punch one by one, and complete the cycle several times. Such an operation method is not only labor-intensive, but also inefficient, and the parts are easily deformed during the transmission process of each process, resulting in unstable parts, poor final product status, non-vertical nut cylinders, broken threads in the ribs, and scrapped The rate is high, and the maintenance workload of the mold is heavy. Contents of the invention [0003] The object of the present invention...
