Abstract

The invention discloses a forging machining process of a parking gear, and relates to the technical field of gear machining. The problems that parking gear machining production efficiency is low, andmaterial waste is serious in the prior art are solved. The machining process comprises the following steps of blanking, outer circle turning, heating, blank making, center hole punching, hot precisionforging, connected skin turning, isothermal normalizing, shot blasting, scale saponification and cold extrusion. The forging process is adopted for parking gear machining, material waste is reduced,a cavity is machined through preforming, and a cake-shaped structure is formed through common preforming. An annular structure with a taper step is adopted and adapts to a product, and when a blank ismachined into the cavity, the peripheral wall of the opening end of the cavity is expanded outwards and inclines to form an opening face, the opening face horizontally extends towards the end face ofa cylindrical body to penetrate through the end face of the cylindrical body, and accordingly, a positioning boss is formed, axial positioning of a die and the blank is facilitated, and the subsequent forging quality is guaranteed. Through the design of the cavity, the forging force requirement of precision forging forming can be reduced.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a forging process of a parking gear. Background technique [0002] The parking gear is a very important safety part in the gearbox, and its precision requirements and parts quality requirements are high; the existing manufacturing process generally uses bar cutting directly, the outer tooth surface is formed by hobbing, and then processed by gear shaping Method for shaping the inner tooth surface. This processing technology has great disadvantages: cutting production efficiency is low, and it is only suitable for single-piece or small-batch production applications. Secondly, the cutting process is used to form the tooth surface, which causes serious waste of raw materials, high cost, and the metal flow line is cut off. The surface strength is low, and it is prone to tooth damage and the phenomenon that the gear cannot be shifted. Contents of the invention [0003] The...
