Description

High-efficient cutting device suitable for axle sleeve

Technical Field

The utility model relates to an axle sleeve production technical field, in particular to high-efficient cutting device suitable for axle sleeve.

Background

In the production process of the shaft sleeve, the shaft sleeve needs to be cut into a proper length so as to adapt to different application occasions. The existing cutting manufacturing methods are of two types. The first is to use a sawing machine, manually position and clamp the uncut sleeve stock on the sawing machine, and then start the machine to saw to the desired size. And finally, respectively turning the sawed shaft sleeve blanks into required lengths. And the second method is to clamp the shaft sleeve raw material on a chuck of a lathe and then use a cutting tool of the lathe to cut a shaft sleeve blank in the rotation process of the shaft sleeve raw material. The first cutting method has problems in that a finishing length is required to be reserved for a sleeve blank when cutting the sleeve blank from a sleeve material, and the reserved finishing length is cut off when finishing the sleeve blank, which results in waste of material. Meanwhile, two processing procedures are required in the first cutting process, so that the processing cost is increased, the economic benefit is poor, and the production efficiency is low. With the second cutting method, although there is no waste of material, in the lathe, the cutting tool is moved but not rotated, and the material is cut through the sleeve during the rotation, so that the cutting tool has only one stress point, limited by the strength of the cutting tool of the lathe, and the rotation speed is generally slow, which results in long cutting time, especially for the sleeve with small size and large number, and poor economic efficiency.
