Manufacturing technology of retaining snap ring for multi-piece small-sized engineering wheel and die

Abstract

The invention provides a manufacturing technology of a retaining snap ring for a multi-piece small-sized engineering wheel and a die. The manufacturing technology comprises the following working procedures that rolling, namely, strip steel is coiled to coiled materials through a rolling machine; welding, namely, end openings of the coiled materials are welded together to form a sealed ring billet; coping, namely, coping is conducted on welding joints; fine shaping, namely, fine shaping is conducted on the size and the shape of a workpiece through the special die to ensure that the workpiece is formed; notching, namely, the workpiece is cut off from the positions of the welding joints; opening milling and prying, namely, an opening is milled and pried in the workpiece which is cut off through a milling machine to form a semi-finished workpiece; heat treatment, namely, heat treatment is conducted on the semi-finished workpiece after the semi-finished workpiece is put in a crawler-type continuous quenching tempering furnace to manufacture the retaining snap ring. The manufacturing technology of the retaining snap ring for the multi-piece small-sized engineering wheel is suitable for manufacturing the retaining snap ring for the multi-piece small-sized engineering wheel, and is high in material utilization ratio, low in manufacturing cost, high in production efficiency and good in retaining snap ring elasticity.

Description

technical field [0001] The invention relates to a lock ring manufacturing process and a special mold, in particular to a multi-piece small wheel lock ring manufacturing process and a special mold. Background technique [0002] The existing multi-piece lock ring for small engineering wheels is generally formed by cutting and blanking the steel plate and then turning it. The process flow is: cutting and blanking the steel plate→turning to the required size→sawing and cutting into two semicircles . [0003] There are serious deficiencies in this manufacturing process in actual production, which are mainly reflected in the following aspects: first, the steel plate is used to blank the material into a circular ring, the material utilization rate is low, and the manufacturing cost is high; The workpiece is small, the clamping is difficult, and the production efficiency is low; the third is for the convenience of installation, it is cut into two semicircles by sawing, and it is ea...
