Embodiment Construction

[0025] The production process of the punching and welding brake mainly includes the process plan of the brake base plate and the air chamber bracket. Among them: the technological process of the brake base plate is: turning center hole and end face, drilling flange hole, countersinking, milling the end face of camshaft hole and milling shoe shaft hole end face, boring, drilling and tapping bracket hole, drilling and tapping dust cover Holes, drilling and tapping four connecting bracket threaded holes; the process flow of the air chamber bracket, as shown in the attached figure, is as follows: 1. The outer cylindrical surface is supported by a V-shaped block, the upper V-shaped pressing block presses the workpiece, and the tool rod drives The tool is used for boring; 2. Locate the camshaft hole and one end surface, and clamp the workpiece by tightening the cone screw to expand the core to clamp the workpiece for turning the end surface; 3. Position the camshaft hole and one end ...

Abstract

The invention relates to a production process of a press-welding brake, which comprises the technical scheme of fabricating a bottom plate and an air chamber bracket. The production process is characterized in that the process of the brake bottom plate comprises the steps of: turning a center hole and an end face, drilling a flange hole, facing, milling the end face of a camshaft hole and the end face of a shoe piece shaft hole, boring, drilling a bracket hole and a dustproof cover hole, and drilling four connecting bracket threaded holes; the process of the air chamber bracket comprises the following steps of: boring, turning the end face, drilling a bottom surface hole, milling an air chamber surface, and drilling an air chamber surface hole and a lubricating nipple hole. By applying the process of the invention, the press-welding brake can be processed by using lathes, milling machines and drilling machines frequently used in the industry. The process has flexible and reliable arrangement without purchasing many special lathes.

Description

technical field [0001] The invention relates to a production process of a stamping-welding brake for a vehicle, in particular to a production process of a brake base plate and an air chamber bracket of the stamping-welding brake, and belongs to the field of manufacturing automobiles and their accessories. Background technique [0002] At present, the brakes are generally drum brakes mainly made of casting materials. With the development of the axle industry, press-welded brakes are becoming more and more popular according to the needs of various manufacturers. Stamping and welding brakes have the advantages of reduced weight, superior structure, and high material utilization. However, the stamping and welding type brake has the problems of high manufacturing cost and complicated manufacturing process. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a production proce...
