Rapid stamping and shaping process for automobile door frame

Abstract

The invention discloses a rapid stamping and shaping process for an automobile door frame. The rapid stamping and shaping process comprises the following steps that a workpiece is pretreated, impurities attached to the surface of a plate are cleaned with a cleaning agent, it is guaranteed that the surface of the plate is clean and tidy, after the plate is dried, the surface of the workpiece is evenly coated with an anti-oxidation coating, and according to the size of a part needing to be stamped, the plate is cut to obtain a metal blank; heating is carried out, a stamping die is heated, the metal blank is heated to 900 DEG C-1100 DEG C, an electric heating mode is adopted for heating, temperature rising is fast, efficiency is high, and heat preservation is carried out on the workpiece after heating; and the initial position of a lower die base is debugged according to the position of an upper die base, so that the upper die base corresponds to the lower die base. The process is simple in step, convenient to operate, reasonable in design of punch forming process parameters and good in using effect, and a punch forming product which is smooth in surface, good in geometric shape and excellent in mechanical performance can be manufactured easily, conveniently and rapidly in a high-quality mode.

Description

Technical field[0001]The present invention relates to the field of stamping type, and more particularly to a fast stamping and stamping process for automotive door frames.Background technique[0002]Car stamping parts, as the name implies, is a metal stamping member that makes up the automobile parts. In the car stamping parts, a part is directly used after the stamping, and the other is soldered after stamping, or after machining, or the process processing such as machining, it can be used as a car parts, and the stamping is a traditional material forming. Process, accompanied by the development of the automotive industry, the stamping process has greatly improved the accuracy and efficiency of the material forming, and the stamped molding can be rushed to a part every 5s, and the accuracy of parts is generally more than 95%. .[0003]As the requirements of automotive production manufacturing, the production and manufacturing of the entire car door frame parts, the quality of the heat ...
