Example Embodiment

[0022] The present invention will be further described below in conjunction with specific embodiments:

[0023] The present invention relates to a manufacturing method of an inner sleeve skeleton, and the method steps are as follows:

[0024] 1) Cold heading billet: After taking the wire and assembling the wire, enter the mold for debugging (that is, manually adjust the feeding device of the equipment to determine whether the material can be smoothly fed into the mold every time), and then apply pressure to the wire through the forming mold. Carry out plastic deformation, and then cooperate with the auxiliary mold to cut the material to make a blank. After the blank is cooled, the size of the blank is measured to ensure that the size is consistent with the drawing;

[0025] Among them, the wire must be made of materials suitable for cold heading, because the material will locally deform significantly during cold heading. In order to prevent waste, ensure the smooth progress of the pr...

Abstract

The invention relates to the technical field of inner bushing frameworks and discloses an inner bushing framework manufacturing method. The inner bushing framework manufacturing method comprises the steps that 1, cold heading is performed for blank manufacturing; 2, rough machining is performed; 3, fine inner-hole blanking is performed; 4, end face finish turning is performed; 5 edge punching and cutting are performed. The steel product utilization rate and production efficiency are greatly improved, the inner bushing framework manufacturing method is suitable for automatic production, and the mechanical properties of obtained parts are more superior.

Description

technical field [0001] The invention relates to the technical field of an inner bush skeleton, in particular to a method for manufacturing an inner bush skeleton. Background technique [0002] The inner bush skeleton is mainly used in the shock absorption of the automobile steering gear. The existing inner bush skeleton is generally processed by cutting. On the CNC lathe, the turning tool is passed on the rough material, and the shape is cut according to the drawing requirements, and then cut, and then Finish the section, and then punch the edge to obtain the product. However, the steel utilization rate of this method is only 18% to 20%. During processing, it is easy to generate waste, the material utilization rate is low, and there are many processing procedures. Moreover, In this method, when machining the inner hole and the outer diameter step, the allowance is too large, resulting in too long processing time for a single skeleton and low production efficiency.
