A hollow stabilizer bar production process

Abstract

The invention discloses a production process of a hollow stabilizer bar, which specifically includes the following steps: (1) blanking, (2) filling the inner sleeve by electric welding, inserting the filled inner sleeve at both ends of the blanking rod respectively, so as to ensure that the end surface of the inner sleeve is filled Slightly 2~3mm inward with the end face of the rod body, and then each end face is fixed with a filled inner sleeve by spot welding; (3) both ends are heated and flattened, and both ends of the rod body with the filled inner sleeve after step (2) are simultaneously Put it into the induction coil for heating, transfer the heated workpiece to the flattening device at the flattening station, and extrude both ends of the workpiece at the same time; (4) Grinding, (5) Drilling, (6) Bending, (7) quenching and tempering, (8) correction, (9) shot blasting, (10) electrophoresis. The invention has reasonable process step design, simplifies the whole production process, reduces the number of operators, lowers the operation intensity, and improves the production efficiency, and the simultaneous flattening of both ends can ensure the flatness of the two ends to ensure the product quality.

Description

technical field [0001] The invention relates to the field of production and processing of hollow stabilizer bars, and mainly relates to a production process of hollow stabilizer bars. Background technique [0002] The production process of the traditional hollow stabilizer bar is: blanking→bending by pipe bender→sawing at one end (equal arm length at both ends)→sawing at the other end (equal arm length at both ends)→tempering→heating and flattening at one end→the other end Heating and flattening→drilling→boring→correction→shot blasting→spraying. The whole process steps are cumbersome, many people are required to participate in the production, and the manual labor intensity is high, time-consuming and labor-intensive, the production efficiency is not high, and the production cost is high. [0003] With the development of production automation and the cost reduction requirements of customers, it is urgent to improve the current hollow stabilizer bar production process, thereb...

The entire process steps are cumbersome, and many people are required to participate in the production, and the manual labor intensity is high, time-consuming and laborious, the production efficiency is not high, and the production cost is high.

[0003] With the development of production automation and the cost reduction requirements of customers, it is urgent to improve the current hollow stabilizer bar production process, thereby improving production efficiency, reducing labor costs, and maximizing product profits; One end of the flattening operation is performed, and then the other end is flattened after one period of flattening. The flattening process is cumbersome, and the flatness of the two ends of the two flattenings cannot be guaranteed, resulting in an increase in the reject rate. When the end is drilled, due to the hollow structure, there will be a certain degree of instability during the drilling process, and the drilling quality is not good, which will affect the later press-fitting of the bushing
