Machining technology and machining forming device of elastic collar

Abstract

The invention provides a machining technology and a machining forming device of an elastic collar. According to the machining technology and the machining forming device of the elastic collar, a stepping feed technology, a grading stamping technology and a multidirectional bend forming technology are adopted to produce the elastic collar, a use ratio of raw materials is greatly improved, and product quality and production efficiency are improved. The machining forming device of the elastic collar comprises a rack, a straightener, a feed mechanism, a punching machine mechanism, a cutting-off mechanism and a forming mechanism, wherein the straightener, the feed mechanism, the punching machine mechanism, the cutting-off mechanism and the forming mechanism are installed on the rack in sequence. Raw material metal wires are firstly straightened by the straightener, and then enter the feed mechanism. The feed mechanism carries out stepping feed according to a fixed step length so as to enable most front ends of the metal wires to enter in sequence. The punching machine mechanism carries out blanking processing on the most front ends of the metal wires so as to form arc-shaped strip blanks with a certain curvature. The cutting-off mechanism carries out cutting-off processing on the formed arc-shaped strips which are processed by blanking, and blanks needed by the forming mechanism are isolated. The forming mechanism curls each arc-shaped strip which is cut off to form a circle with an opening.

Description

technical field [0001] The invention relates to a processing method and equipment for an elastic retaining ring, in particular to a processing technology and forming of an elastic retaining ring that can greatly improve the utilization rate of raw materials, reduce production costs, improve product quality and increase production efficiency device. Background technique [0002] The domestic industrialization process started late, but the development speed is extremely fast, which requires the relevant basic industries to keep up with the pace. As a standard part, retaining rings are widely used in industrial production, and the demand is rapidly expanding. The retaining ring is a ring-shaped part fastened on the shaft, which can prevent other parts mounted on the shaft from moving. It is widely used in all walks of life where there are shafts. It is in great demand. English name: [closing] ring, the main materials are carbon spring steel and stainless steel. [0003] At pr...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the domestic production of retaining rings is still in accordance with the traditional process. The two processes of punching and blanking are completed on ordinary punching machines. The utilization rate of raw materials is extremely low. According to this process, the material utilization rate of retaining rings for φ55 holes is only about 17%. In addition, Too much manual participation makes the product quality extremely unstable. Each process is 10,000 pieces / 8 hours, the efficiency is extremely low, and the cost is high; moreover, too much manual operation makes the personnel easy to fatigue, and the accident rate is high. , the general carbon spring steel and stainless steel have certain lines, the traditional stamping process will destroy the lines of carbon spring steel and stainless steel, resulting in a certain impact on the strength of the elastic retaining ring
