Abstract
The invention relates to a processing technology of an inner gear spline. The processing steps are as follows: firstly carrying out rough processing on inner teeth on an oil press through a push-type broach, and then carrying out finish broaching and forming on the inner gear spline on a broaching machine through a solid broach. Through adopting the oil press to conduct rough processing through the push-type broach and adopting the broaching machine to conduct finish broaching and forming through the solid broach, the product quality and the production efficiency are improved, and the service life of a tool is prolonged, the problem of short service life of a forming tool due to materials of the tool in the domestic country is solved, and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of spline processing technology, is a kind of new technology of machining interal spline specifically.
Background technology
Because automobile engineering machinery, internal gear transmission is used in the industry transmission in a large number, traditional processing method is gear shaping, gear shaping production efficiency is low, and the accumulation transmission through gear shapping machine transmission chain error, error of cutter, frock clamp error, end product quality poor stability, particularly accumulated error cause greatly the whole transmission system life-span low, noise is high.External advanced processing method is to adopt the broaching one-shot forming, whole product quality is determined by cutter and frock, constant product quality, production efficiency is high, but the cost of charp tool is higher, and particularly at present at home because the material of cutter is whole rolling, its quality is unstable, there is process safety hidden danger, affects normal production efficiency.
Summary of the invention
The invention provides a kind of working (machining) efficiency height, steady quality, the processing technology of saving the internal gear spline of processing cost.
The present invention is by the following technical solutions: a kind of processing technology of internal gear spline, its procedure of processing is: at first adopt push type broach to carry out internal tooth roughing at hydraulic press, carry out finish draw shaping internal gear spline with solid broach again on broaching machine.
Adopt push type broach to carry out internal tooth roughing at hydraulic press, can select the short sword tool, have larger cutting output, be convenient to roughing; Be shaped and on broaching machine, carry out finish draw with solid broach, can guarantee product fine finishining quality and cutter life.
The present invention adopts hydraulic press to carry out roughing by push type broach, the recycling broaching machine carries out finish draw by broaching tool and is shaped, be conducive to improve the quality of products, production efficiency and cutter life, solved domesticly because the cutter material problem causes the forming tool problem in service life, reduce production costs.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
A kind of processing technology of internal gear spline, its procedure of processing is: at first adopt push type broach to carry out internal tooth roughing at hydraulic press, carry out finish draw shaping internal gear spline with solid broach again on broaching machine.
