Machining method of automobile electric seat motor fixing seat

Abstract

The invention relates to the technical field of machining, and particularly relates to a machining method of an automobile electric seat motor fixing seat. The machining method comprises the followingmachining steps that punch forming is conducted, specifically, raw materials are machined into a preset shape, and a workpiece is separated from the raw materials; extrusion forming is conducted, specifically, the workpiece is extruded in a pressurizing mode, and pressure maintaining is conducted on the workpiece, so that an arc surface of the workpiece is machined; and one-stop machining formingis conducted, specifically, a side hole and a front hole are machined in the workpiece, and the workpiece is trimmed. According to the automobile electric seat motor fixing seat, the machining precision of the side hole and the front hole can be guaranteed; the workpiece is extruded in the pressurizing mode, and pressure maintaining is conducted on the workpiece, so that the arc surface of the workpiece is machined; the workpiece flows from the center of a cavity to the two sides in the pressurizing process, so that the workpiece is prevented from cracking; and pressure maintaining is conducted on the workpiece after pressurizing is completed, so that the workpiece is prevented from rebounding and not formed in place. The automobile electric seat motor fixing seat machined through the machining method is high in machining precision, low in defective rate and high in product machining quality.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a motor fixing seat of an automobile electric seat. Background technique [0002] The car electric seat motor mount is a metal part, such as figure 1 As shown, it has an arc surface 1, a side hole 2 and a front hole 3, which are mainly used to fix the motor for adjusting the front and rear positions of the front seats, and cooperate with the screw to realize the front and rear adjustment of the seats. [0003] In the prior art, the method for processing the motor fixing seat of the automobile electric seat is mainly to use a continuous punching machine for processing, but since the motor fixing seat of the automobile electric seat has a circular arc surface 1 that cooperates with the motor screw part. If the shape of the car electric seat motor fixing seat is first processed on the continuous punching machine without adding the arc surface 1...

Problems solved by technology

[0003] In the prior art, the method for processing the motor fixing seat of the automobile electric seat mainly uses a continuous punching machine for processing, but since the motor fixing seat of the automobile electric seat has a circular arc surface 1

If the shape of the car electric seat motor fixing seat is first processed on the continuous punching machine without adding the arc surface 1, then the arc surface 1 needs to be processed by a subsequent lathe, resulting in a decrease in strength, and the car electric seat motor is fixed. After the seat is formed, stress relief treatment is required, which will easily cause the side hole 2 and the front hole 3 on the workpiece to be misaligned, and the machining accuracy is low

If the circular arc surface 1 is processed by stamping and forming in a short period of time with constant pressure on a continuous punching machine, it is easy to cause cracking, rebound, or even improper forming.
