A one-time stamping forming sprocket process

Abstract

The invention discloses a one-time stamping process for forming a sprocket, which comprises the following steps: preparing a circular plate to be stamped, installing a stamping die on a fine blanking machine, spraying volatile stamping oil on the surface of the circular plate, and passing two Place the circular plate on the lower die with two positioning columns; start the fine-blanking punching machine for trial punching, and then adjust the punching depth of the fine-blanking punching machine; remove the stamped parts after stamping, and remove the waste around the lower die , In this way, the continuous production of stamping parts is carried out; the stamping parts are deburred and polished to form semi-finished blanks; the semi-finished blanks are quenched and tempered to complete the production of sprockets. The invention adopts one-time stamping forming, fine blanking die and fine blanking machine, high precision, relatively low error, smooth tooth root and tooth tip, can better cooperate with the chain, reduce friction with the chain, and increase the service life.

Description

technical field [0001] The invention belongs to the technical field of sprocket production, and in particular relates to a one-time stamping forming sprocket process. Background technique [0002] A sprocket is a wheel with cog-type sprockets designed to engage precisely pitched blocks on a chain link or cable. Sprockets are widely used in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries for mechanical transmission, etc. [0003] The precision of the gears produced by the traditional hobbing process is difficult to meet the standard, and the tooth root is uneven and has obvious knife lines, which greatly reduces the service life of the gears and chains. The service life is less than 10,000 kilometers, and the processing technology is relatively complicated. Time consuming and power consuming. [0004] Therefore, we propose a one-time stamping...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a one-time stamping and forming sprocket process to solve the above-mentioned background technology that the gear precision produced by the traditional gear hobbing process in the prior art is difficult to meet the standard, and the root of the tooth is uneven, and there are obvious knives. grain, thus greatly reducing the service life of gears and chains. The service life is less than 10,000 kilometers. The processing technology is more complicated, time-consuming, and power-consuming.
