Abstract

The invention discloses a method for machining a steel snap ring and a device for realizing the method, relates to a machining technique of a steel snap ring, and aims to solve the problems that a conventional machining method is complex, numerous in procedure, low in pass percent, high in cost and long in production period. The method comprises the following steps: coiling a blank profile which is appropriate in cross section size and length into a multi-circle ring part by using a method for manufacturing a tightly coiled helical spring, wherein the multi-circle ring part has multiple circles and the circles are tightly contacted; cutting the multi-circle ring part into a single-circle snap ring blank; setting clamping heads at two ends of the blank; tightening an iron wire hooping knot on the outer circle of a cylindrical barrel, inserting a fastening bolt and a lifting eye nut into the cylindrical barrel, a top cover and a bottom cover so as to connect and tightly press the cylindrical barrel, the top cover and the bottom cover, tempering, remaking the iron wire hooping knot, tempering again, and cutting. By adopting the method, the beneficial effects that 7 procedures are reduced to 3 procedures, the pass percent is increased by 20%, the machining cost is halved and the machining time is halved can be achieved, and the method is applicable to the field of snap ring machining, and particularly to machining of steel snap rings.

Description

technical field [0001] The invention relates to a processing method of a split ring and a device for realizing the method, in particular to a processing method of a steel split ring and a device for realizing the method. Background technique [0002] Steel split rings refer to circular ring products with openings made of steel, including piston rings, elastic rings, etc.; the ring cross-section of steel split rings can be square, flat square or round. There are seven processes in the processing of such products: 1. Material preparation; 2. Blank forming (forging or casting); 3. Rough cutting of blank; 4. Heat treatment (quenching and tempering), 5. Semi-finishing machining; 6. Heat setting (with a fixture); 7. Fine cutting. This processing method has many processing steps and complicated manufacturing process, so the production cycle of the product is long, the qualified rate is low, and the cost is high. Contents of the invention [0003] The purpose of the invention is...
