Abstract
This article describes the design of self-made 20T broaching machine. Broaching machine is a machine which using the pulling knife to processing various internal and external surface molding. Broaching machine only has the linear motion of the broach, which is the main movement processing, feed movement by pulling the knife is to achieve the structure itself. Specialized broaching machine also indicates that its high price, and sometimes it does not require so much high precision, and the use of these types of broaching machine is also a waste. This requires its own factory can manufacture a few simple and can finish most of the broaching processing machines. The self-made broaching machine is without doubt a good choice, its structure is very simple, very little timber ,and it can choose a number of standard parts to the assembly. Although some parts are not standard parts of their factory, the processing is also very easy. And therefore low cost for small and medium enterprises is the best choice. Broaching machine in this article is mainly used for the aperture broaching, keyway broaching. It’s composed mainly by the bed structure, power agencies, transmission, ancillary part and so on. It mainly uses the leather belt drive,worm reduction gear ,glide screw nut drive to complete the broaching work. This design has rational structure, low cost, high efficiency, good performance, and easy to operate.
Key words: self-made broaching machine worm gear glide screw nut
