Abstract

The invention relates to a progressive die for a surface plate of an electric vehicle seat lock and belongs to dies in the field of electric vehicles. The progressive die comprises an upper die, a lower die, a lifer pin, a guide needle, a quick change device, a safety device, a trimming die, a folding die, a punching die and a cut-off separation die, wherein the lifter pin is arranged on a lower die plate; the guide needle is fixedly arranged on a stripper plate; the safety device is fixedly arranged on a lower die holder; the quick change device comprises a male die punch and a male die insert; the male die punch is fixedly arranged on an upper die fixing plate; the male die insert is fixedly arranged on a lower die plate; male dies in the trimming die, the folding die, the punching die and the cut-off separation die are sequentially and fixedly arranged on the upper die fixing plate. According to the progressive die disclosed by the invention, the punch is enabled to finish punching work procedures for multiple times at different positions of a workpiece in the primary stroke, and thus the cost is reduced, the production efficiency is increased and the stability is improved.

Description

technical field [0001] The invention relates to a mold, in particular to a continuous mold for locking plane plates of automobile seats, which belongs to molds in the field of automobiles. Background technique [0002] Continuous die refers to the cold stamping die that uses strip-shaped stamping raw materials in one stamping stroke, and uses several different stations on a pair of molds to complete multiple stamping processes at the same time. Move once with a fixed distance until the product is completed. [0003] The existing mold of the car seat lock flat plate is generally composed of a punch and a die, and can also be composed of multiple punches and multiple dies, but the punch can only complete one type of punch in one stroke. In the blanking process, this mold not only requires more production equipment, but also requires more operators, and has defects such as insufficient stability and poor safety, which cause the company to waste a lot of labor and machinery cos...

[0003] The existing mold of the car seat lock flat plate is generally composed of a punch and a die, and can also be composed of multiple punches and multiple dies, but the punch can only complete one type of punch in one stroke. In the punching process, this mold not only needs more production equipment, but also needs more operators, and has defects such as insufficient stability and poor safety, which cause the company to waste a lot of labor and machinery costs

[0004] Chinese Patent No. 201110317084.8 discloses an invention patent named "Stamping Die for Car Seat Mounting Bracket Processing", which includes an upper mold base and a lower mold base, wherein the two sides of the bottom of the upper mold base Both are equipped with positioning sleeves, and both sides of the top of the lower die base are provided with positioning guide posts. The upper die base and the lower die base are in the process of laminating, and the positioning guide posts are inserted into the positioning sleeves. Although the structure of this patent Simple, but the punch press can only complete one punching process in one stroke, so it still has the above defects
