Abstract

The invention discloses a forming process of a hydraulic brake oil pipe of an engine. The process comprises the following steps: discharging; coarse grinding; smoothing; reducing; accurate grinding; inner hole treatment and drying; table upsetting; tube head upsetting; right step upsetting; bending; inspection; thermal treatment; and electroplating. The process disclosed by the invention has the characteristics of being simple in process, attractive in appearance of product, high in controllability of product quality, high in rate of finished products and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing and processing of pipe fittings, in particular to a forming process of an engine hydraulic brake oil pipe. Background technique [0002] Engine hydraulic brake oil pipes must be used in the field of auto parts, especially in engine manufacturing. Due to the structure of the engine itself, the hydraulic brake oil pipe is limited to a structure with a boss, a step in the middle, and a certain angle. At present, the general-purpose hydraulic brake oil pipe is processed by ductile iron castings. The specific process is: first bend the tubular wood mold, and then make a metal pattern. Castings can only be made into finished products after sand cleaning, burr treatment, machining and other processes. This method has the disadvantages of complex manufacturing, low production efficiency, large equipment investment, and high cost. It does not conform to the trend of energy saving, emission reducti...
