Machining method of axial joint fork

Abstract

The invention discloses a machining method of an axial joint fork and relates to the technical field of mechanical part production methods. The machining method includes the following steps that S1, round steel with the diameter being 60 mm is selected, and a blank piece is cut off till length is 158 mm; S2, the blank piece in the step S1 is placed in a medium-frequency heating furnace to be heated; S3, an air hammer is used for performing hammer drawing on one end of a workpiece obtained in the step 2; S4, the workpiece subjected to hammer drawing is placed in a friction press for hot forging of the workpiece; S5, the hot forged workpiece is placed in a punching machine to be subjected to edge cutting and hot correction treatment; S6, the workpiece subjected to hot correction is subjected to heat treatment; S7, the workpiece subjected to heat treatment is subjected to shot blasting treatment; S8, the workpiece subjected to shot blasting treatment is subjected to cold correction treatment; and S9, a part subjected to cold correction treatment is packaged. By means of the machining method of the axial joint fork, the symmetry degree of the product is high, the position degree error of the product is small, the product hardness is high, the product quality is good, the service life of the product is greatly prolonged, and the batch producing and machining requirement of axial joint fork pieces is met.

Description

technical field [0001] The invention relates to the technical field of production methods of mechanical parts, in particular to a processing method of an axial yoke. Background technique [0002] Some auxiliary parts that are often used in vehicles and mechanical equipment have irregular shapes. The axial fork is a common type of such parts. Due to the particularity of its shape and the importance of its performance, it increases In addition to the difficulty of forging and forming, the distribution of materials and the selection of processes need to be carefully considered. Generally speaking, the machining accuracy of the plane is easier to guarantee than the machining accuracy of the hole. Therefore, this design follows the principle of face first, and the machining of the plane is clearly divided into rough machining and finishing stages to ensure the accuracy of the hole. Precision. When formulating the process specification, the surface is processed first, and then t...
