Automobile external covering part stamping die achieving lateral reshaping by using hydraulic system to drive sliding blocks

Abstract

The invention discloses an automobile external covering part stamping die achieving lateral reshaping by using a hydraulic system to drive sliding blocks and belongs to the technical field of stamping dies. The automobile external covering part stamping die comprises an upper die body and a lower die body. The lower die body is provided with a workpiece male die base. A rotary die body is rotatably mounted on the upper die body through an articulated shaft. One end of the rotary die body is connected with a hydraulic cylinder. The bottom of the other end of the rotary die body is connected with a translational pad base. The translational pedestal is provided with protruding pad parts. The rotary die body is provided with grooves. The workpiece male die comprises a male die body and a negative-angle die body. A sliding bevel is arranged between the negative-angle die body and the male die body. The upper die body is provided with a workpiece female base. The upper die body is provided with a tapered wedge sliding base. A pressing plate is fixedly arranged on the tapered wedge sliding base. First reset springs are arranged between the tapered wedge sliding base and the upper die body. The lower die body is provided with a tapered wedge fixing base. The automobile external covering part stamping die can be used for stamping and forming negative-angle products, and the quality of the stamped and formed product is stable; the service life is long, and the automobile external covering part stamping die is widely applied to machining of automobile covering parts.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a precision hydraulic stamping die for stamping automobile panels. Background technique [0002] In order to meet the requirements of strength, function, shape and other aspects of automobile panels, the shape of the parts is often very complicated. The hole position and shape on the complex shape are often the prerequisites to ensure the smooth installation of the key parts of the car, and the holes and the complex shape on the complex surface have their own particularity. The oblique wedge mechanism plays a role in solving the complex size and shape of complex stamping parts in the stamping die. During production and manufacturing, the oblique wedge mechanism is used to realize stamping work at different angles to meet the requirements of different hole positions and surface differences. For stamping Four-sequence, the application of the wedge mechanism is an indispensab...

Problems solved by technology

The oblique wedge mechanism plays a role in solving the complex size and shape of complex stamping parts in the stamping die. During production and manufacturing, the oblique wedge mechanism is used to realize stamping work at different angles to meet the requirements of different hole positions and surface differences. For stamping Four-sequence, the application of the wedge mechanism is an indispensable part. Often a set of molds realizes multiple processes, such as the combination of vertical flanging and side flanging, and the combination of flanging, punching and other processes. However, In the stamping process of the stamping die, the wedge mechanism cannot be used to achieve negative angle flanging. For example, when the outer panel of the car door needs to be combined with the inner panel, the outer panel must be turned into a negative angle, and the shape of the outer panel of the car door is an arc. After forming, the punch cannot translate and retreat, and the traditional stamping die cannot realize the operation of taking out the workpiece after stamping. Therefore, the negative angle processing of such parts is a technical problem that needs to be urgently solved for the stamping die
