Process for machining and manufacturing supporting ring

Abstract

The invention relates to a process for machining and manufacturing a supporting ring, which is characterized in that the machining process steps are carried out according to the following sequence that: (A) firstly, a cut Q235 steel material is machined into an annular rough piece of the supporting ring through processes of hot pressing and stretching; (B) a workpiece is clamped on a lathe based on an inner hole and the end face of a small end; the end face of a large end is machined by the lathe till a lustrous band appears; and the height is between 60 and 70; (C) the outside diameter of the large end is machined; the diameter of the large end is machined between phi535 and phi545; (D) based on the outside diameter and the end face of the large end, the workpiece is clamped; the end face of the small end is machined into flatness; the height is between 55 and 65; (E) the inside diameter of the small end is machined to allow that the small end is transferred to a numerically controlled lathe after the inside diameter reaches between phi455 and phi 465; based on the outside diameter and the end face of the large end, the workpiece is clamped; the outer profile of the workpiece is machined; (F) based on the outside diameter of the large end and the end face of the small end, the workpiece is clamped; the inner profile of the workpiece is machined; and (G) burr in cusp is removed. Compared with the prior technical process, the process has the advantages of high product precision, attractive profile, light weight, durability, small material consumption and low machining cost.

Description

technical field [0001] The invention relates to the technical field of truck wheel manufacturing, in particular to a manufacturing process for a support ring. Background technique [0002] At present, most truck wheels generally adopt the traditional rim and spoke welding synthesis. The disadvantages or shortcomings are that the spokes are heavy in weight, the processing technology is relatively complicated, the material consumption is large, and the processing cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a support ring manufacturing process that can make the product more precise, more economical, more practical and lighter, aiming at the above-mentioned defects in the prior art. [0004] Its technical scheme is: carry out the processing steps in the following order: (A) first process the cut Q235 steel material into a ring-shaped blank of the support ring through hot pressing and stretching processes; (B) use the smal...
