Production technology of big truck hub brake spring B

Abstract

The invention discloses a production technology of a big truck hub brake spring B, and belongs to the field of the production technology of the brake spring. The technical scheme of the production technology is characterized by comprising following steps: S1, a first process step: a middle tension spring semi-finished product is manufactured by a spring eight-claw machine through winding; and a second process step: the middle tension spring semi-finished product is subjected to destressing treatment; S2, the middle tension spring is subjected to shot blasting treatment; S3, a first process step: a left drag hook semi-finished product and a right drag hook semi-finished product are manufactured by the spring eight-claw machine through winding; and a second process step: the left drag hook semi-finished product and the right drag hook semi-finished product are subjected to destressing treatment; S4, stamping assembly is carried out by an oil press die; S5, the big truck brake hub springis placed in a tempering furnace and subjected to destressing treatment; S6, the big truck hub brake spring is subjected to length direction; S7, the big truck hub brake spring processed by S6 is subjected to alramenting treatment; and S8, the big truck hub brake spring is packaged and put in storage. The production technology has the advantage of improving comprehensive performance of the big truck hub brake spring B.

Description

technical field [0001] The invention relates to the field of brake spring production technology, in particular to a production technology of brake spring B for a large truck wheel hub. Background technique [0002] Braking is commonly known as "braking". Refers to the action of stopping or reducing the speed of running locomotives, vehicles and other means of transport or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install a corresponding brake shoe, belt or disc on the machine base, and make it generate braking torque under the action of external force. [0003] The braking system is generally divided into mechanical, hydraulic, pneumatic, electromagnetic, etc. An indispensable part of the mechanical braking system is the hub brake spring. When braking, the hub brake spring will be greatly affected. Therefore, the requirements for the performance of the hub brake spring are very high. [0004] like figure...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown, the hub brake spring B of this large truck mainly consists of a left hook B1, a right hook B2 and a middle tension spring B3. Because spring B is used on large trucks, its working environment is more harsh, and it is necessary for large truck hub brake spring B to have better mechanical properties. Therefore, the performance requirements for large truck hub brake spring B are more stringent. The existing production process produces large Truck hub brake spring B cannot meet performance requirements
