Manufacturing process for automobile steering ball

Abstract

The invention discloses a manufacturing process for an automobile steering ball. The process includes the following steps of (1) cutting of a raw blank; (2) heating of the raw blank; (3) forging forming of the raw blank; (4) thermal treatment of a steering ball; (5) shot blasting of the steering ball; (6) turning of the steering ball; and (7) packaging of the finished steering ball. The structure is simple, practicability is high, and the heating temperature and machining allowance in the manufacturing process for the automobile steering ball are strictly controlled, so that the machining quality of the steering ball is better, and the precision level is higher; meanwhile, a ball head part and a ball rod part are subjected to forging forming through different dies, the defective rate is effectively lowered, and the cost is reduced; and the manufacturing process is simple, meets practical production requirements and increases the comprehensive utilization rate.

Description

technical field [0001] The invention relates to a manufacturing process of an automobile steering ball joint. Background technique [0002] Steering ball joints, also known as ball stud pins or universal joints, refer to mechanical structures that use spherical connections to achieve power transmission on different axes. The universal joint is a very important part of the car. The combination of universal joint and transmission shaft is called universal joint transmission. On vehicles with front-engine rear-wheel drive, the universal joint transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle final drive; while the vehicle with front-engine front-wheel drive omits the drive shaft, the universal joint is installed Between the axle shaft of the front axle, which is responsible for both driving and steering, and the wheels. Although the ball stud in auto parts is small in size, its technical content is not low. It...

Problems solved by technology

[0003] The manufacturing process of the existing steering ball head is complicated, which is not convenient for actual use and production, and cracks often appear in the connection between the ball head and the ball head rod in actual processing and production, resulting in a large amount of waste and increasing production costs

Due to the different functions between the ball head and the ball head rod, the processing accuracy requirements of the two are different. However, the existing forging process of the ball head and the ball head rod is generally formed by a mold, which not only increases the It is difficult to make, and the processing accuracy level is poor
