High-precision stamping die for automobile part machining

Abstract

The invention relates to the technical field of automobile part stamping dies, in particular to a high-precision stamping die for automobile part machining. The stamping die comprises an upper die and a lower die, the upper die and the lower die are jointly and fixedly mounted on a stamping die driving device, and the driving device is used for driving the upper die and the lower die to open and close. The driving device drives the upper die and the lower die to be opened, a demolding mechanism plays a role in the opening process, positioning of a special-shaped stamping piece is relieved through a linkage descending and positioning mechanism of a linkage mechanism, then the special-shaped stamping piece is pushed out from the lower die to be demolded, a worker or a manipulator can conveniently extend to the edge of the lower die to take out the special-shaped stamping piece, on one hand, the situation that taking is interfered due to the fact that a stamping die piece needed by the special-shaped stamping piece is complex after the machine or the hand takes the special-shaped stamping piece is avoided, taking is convenient, and on the other hand, the problem that the hand and the manipulator extend into the stations of the die to cause scratches is avoided.

Description

technical field [0001] The invention relates to the technical field of stamping dies for auto parts, in particular to a high-precision stamping die for processing auto parts. Background technique [0002] Auto parts are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturing plants are also developing rapidly. [0003] The existing technology discloses some invention patents related to auto parts stamping dies. The Chinese patent application number is 201821247836.1, which discloses a high-precision auto parts production die, which involves the field of auto parts processing technology. The mold for high-precision auto parts production includes an upper fixing seat and a lower fixing seat, the upper fixing seat is located above t...

Problems solved by technology

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a high-precision stamping die for auto parts processing, including an upper die and a lower die, and the upper die and the lower die are fixedly installed on the stamping die driving device together. The driving device is used to drive the opening and closing of the upper mold and the lower mold. The upper mold has a stamping head, and the lower mold has a stamping groove. Both sides of the inner wall of the stamping groove are fixedly connected with the first shaping module and the second mold. A sizing module, the inner wall of the stamping groove is slidably connected with a movable support mold up and down, and both sides of the movable support mold are in sliding contact with the inner surfaces of the first sizing module and the second sizing module. The bottom is fixedly connected with the bottom of the inner wall of the stamping groove through the third return spring, and the top of the movable support mold is placed with special-shaped stamping parts, and the side and top of the movable support mold are jointly connected with a positioning mechanism, and the positioning mechanism can hold the special-shaped stamping parts. The stamping parts are positioned laterally, and the side of the lower mold is connected with a demoulding mechanism for demoulding the special-shaped stamping parts. A linkage mechanism is connected between the demoulding mechanism and the positioning mechanism. During the molding process, the positioning ability of the positioning mechanism can be automatically released; when working, when stamping special-shaped parts of automobiles in the prior art, when stamping special-shaped parts, it is necessary to position and support the stamping part, and then give way to support the special-shaped end. Therefore, after the stamping is completed, it is necessary to avoid the various positions of the special-shaped parts, and it is difficult to demould. It is necessary to extend the hand into the stamping station with a manipulator or manually to adjust and take it. On the one hand, it is difficult to take it and needs to be constantly adjusted. On the other hand, when the hand passes through the mold parts, it is easy to be hurt by the special-shaped mold parts set up for the special-shaped parts afterwards. This technical solution can solve the above problems. The specific working method is as follows. When stamping, the special-shaped stamping The parts rest on the top of the movable support mold, and the movable support mold laterally positions the special-shaped stamping parts on the top of the first shaping module, the second shaping module and the movable supporting mold through the positioning mechanism, and then drives the upper mold through the driving device. The mold and the lower mold are clamped, and the upper mold drives the stamping head to press the stamping part of the special-shaped stamping part into the stamping groove, and it is stamped and formed under the support of the first shaping module, the second shaping module and the movable support mold, and in the stamping process During the process, under the action of the third return spring, the movable support mold has the ability of elastic expansion and contraction. When faced with a huge stamping force, it has the ability to buffer instantaneously, so as to avoid the impact of the stamping head on the force-bearing surface of the stamping parts of the opposite sex. Cause damage. After the stamping is completed, the upper mold and the lower mold are driven to open by the driving device. The demoulding mechanism will work during the opening process. First, the positioning mechanism will release the positioning of the special-shaped stamping parts under the linkage of the linkage mechanism. Then, the special-shaped stamping parts are pushed out from the lower mold for demoulding, so that the staff or the manipulator can reach the edge of the lower mold to take out the special-shaped stamping parts. The stamping die parts required by the parts are complicated and interfere with the taking, which is convenient for taking, and on the other hand, avoids the problem of scratches caused by the hands and manipulators extending into the mold station
