Machining technology for front wall lower transverse beam connection piece of automobile

Abstract

The invention provides a machining technology for a front wall lower transverse beam connection piece of an automobile. The machining technology comprises the following steps that S1, sheet metal is subjected to drawing through a drawing die, wherein the drawing depth is half of the depth of a part, the drawing die is provided with a limiting block, and the limiting block on the drawing die is adjustable in height; S2, a drawing part is subjected to primary appearance residue cutting through a laser cutting machine; S3, the part obtained in the S2 is subjected to secondary drawing through thedrawing die, wherein the secondary drawing depth is equal to the depth of the part; and S4, secondary appearance cutting is conducted on the drawing part subjected to flanging through a three-dimensional laser cutting machine. According to the machining technology, a complex part of an electric car needing nine procedures is optimized, thus, a finished product can be obtained through only four procedures, only one forming mold needs to be developed, part production can be achieved through two times of laser cutting, and the problems that parts of an electric car is large in development capitaland long in production cycle, and parts cannot be provided in time are thoroughly solved.

Description

technical field [0001] The invention relates to a manufacturing method of an automobile part, and more particularly relates to a processing technology of a lower beam connecting piece of an automobile cowl. Background technique [0002] Electric vehicles are the automobile industry that has grown rapidly in the past five years. The country encourages, supports and subsidizes electric vehicles from the strategic height of long-term development. The purpose is to completely replace fuel vehicles with new energy vehicles and return humanity an infinite polluted living environment. Rechargeable or replaceable lithium battery electric vehicles are widely used in many fields such as urban online car-hailing, logistics vehicles, and urban buses. Due to the short development cycle of electric vehicles, complex parts, low output and urgent requirements, if the whole process of mold production is developed according to conventional parts, the investment will be large and the producti...
