Manufacturing process of disc brake upper pump

Abstract

The invention relates to a manufacturing process of a disc brake upper pump. The manufacturing process is characterized by comprising the following steps that 1, mold-casting is carried out on a raw material to prepare a disc brake upper pump blank piece, the upper pump blank piece comprises an oil cup connecting end used for being connected with an oil cup, and a handle connecting end used for being connected with a brake handle; 2, a leftover material of the disc brake upper pump blank piece is cut off and burrs are removed; 3, sand blasting treatment is carried out on the disc brake upper pump blank piece; 4, mechanical machining is carried out on the disc brake upper pump blank piece which is subjected to the sand blasting treatment; 5, coating treatment is carried out on the disc brake upper pump blank piece which is machined through the step four so as to obtain a disc brake upper pump finished product piece; and 6, assembling is carried out on the coated disc brake upper pump finished product piece.

Description

Technical field [0001] The invention relates to the field of motorcycle disc brake upper pumps, in particular to a manufacturing process of disc brake upper pumps. Background technique [0002] In the prior art, the traditional manufacturing process of a disc brake upper pump generally includes the following steps: gravity casting, material cutting, burring, T6 heat treatment, sand throwing, mechanical processing, painting, and assembly. The mechanical processing includes the following steps: turning holes, drilling plunger holes (gun drill or drilling + stranding), milling handle grooves (including straight grooves), drilling oil supply holes and oil return holes, drilling handle holes, drilling half-cover holes , Drilling oil cup hole, drilling switch hole, milling oil cup surface, drilling side mirror, drilling oil hole, burr packing. However, the traditional mechanical processing equipment requires at least 2 CNC machines, 3 milling machines, 1 ordinary bench drill, 1 specia...

Problems solved by technology

However, the traditional mechanical processing equipment requires at least 2 CNC machines, 3 milling machines, 1 ordinary bench drill, 1 special bench drill, 5 three-station bench drills, a total of 12 machine tools; each process is operated separately, and materials are stacked on site More materials are discharged slowly. If you want to operate continuously, the relationship between semi-finished products and finished products is generally more than 10:1; the production cycle of the machine is unbalanced, the error is large, the scrap rate is high, and there are many operators, and the machine occupies a large area and the labor cost , High plant cost

[0003] Furthermore, there is a one-to-one connection between the existing oil cup and the disc brake upper pump, that is, one type of brake upper pump can only be installed with the corresponding type of oil cup, and the model of the brake upper pump or oil cup cannot be replaced at will. , or the brake upper pump and the oil cup are integrally formed, but this setting is not only unsightly in appearance but also difficult to maintain and replace, and the structure of one-to-one connection has resulted in the development of new oil cups or new disc brake upper pumps. It is necessary to re-open the mold to adapt to the original structure for connection. The cost of each mold opening is about 20,000 yuan, resulting in high R&D costs and time-consuming and laborious
