Continuous stamping die for parent track material sheets of automobile seat slide rail

Abstract

The invention relates to the technical field of stamping dies for automobile spare parts, in particular to a continuous stamping die for parent track material sheets of an automobile seat slide rail to solve the technical problem that when an existing continuous stamping die for parent track material sheets of an automobile seat slide rail is used for stamping, to-be-stamped strip-shaped raw materials are prone to displacing towards the lateral sides of the die. The continuous stamping die for the parent track material sheets of the automobile seat slide rail is provided with a stamping limiting mechanism located on one lateral side of the die. The stamping limiting mechanism comprises an upper cushion block, nitrogen springs, an upper press block, a guide block, a plug pin, an oblique-surface slide block, an oblique-surface insert block, a backer, reset springs, nuts and screws. The guide block is provided with a plug pin hole matched with the plug pin. By adoption of the stamping limiting mechanism, displacement of the to-be-stamped strip-shaped raw materials towards the lateral sides of the die during stamping can be prevented.

Description

technical field [0001] The invention relates to the technical field of stamping dies for auto parts, in particular to a continuous stamping die for car seat slide rail mother rail material pieces. Background technique [0002] In the existing continuous stamping die for the parent rail material of the car seat slide rail, when the strip-shaped raw material is conveyed, there is usually a small gap between the side of the strip-shaped raw material and the side of the lower die. The reason for this design is: when the strip-shaped raw material is conveyed , not only must it be able to be accurately fed into the stamping station to ensure the progress of the position, but also the side of the strip-shaped raw material must not be damaged during the conveying process. If the gap is too large, the position accuracy of the conveying direction is not enough. There is a possibility of deformation or abrasion of the sides of the strip raw material. But this kind of mold, when punchi...

Problems solved by technology

[0002] In the existing continuous stamping die for the parent rail material of the car seat slide rail, when the strip-shaped raw material is conveyed, there is usually a small gap between the side of the strip-shaped raw material and the side of the lower die. The reason for this design is: when the strip-shaped raw material is conveyed , not only must it be able to be accurately fed into the stamping station to ensure the progress of the position, but also the side of the strip-shaped raw material must not be damaged during the conveying process. If the gap is too large, the position accuracy of the conveying direction is not enough. Potential to deform or fray the sides of the strip raw material

However, when this kind of mold is punching the strip-shaped raw material, due to the existence of a small gap, the strip-shaped raw material will be displaced obliquely upward from the side of the lower die, which will affect the stamping accuracy.
