Linkage control method of files, chopping knives and feeding mechanism

Abstract

The invention discloses a linkage control method of a file, a cleaver and a feeding mechanism. The control method comprises the following steps: (1) obtaining a contact range and a feed range of a cam, wherein the contact range is a corresponding angle range of the cam when the cleaver is cut into the surface of a workpiece until the cleaver gets away from the surface of the workpiece, and the feed range is a corresponding angle range of the cam when the cleaver gets away from the surface of the workpiece until the cleaver comes into contact with the surface of the workpiece for a next time; (2) obtaining a cleaving tooth period of the cleaver according to the rotation speed of the cam and the feed range; (3) obtaining a predetermined feeding speed according to the cleaving tooth period and a file cut range; (4) controlling the feeding mechanism to stop feeding when the cam is in the contact range; (5) controlling the feeding mechanism to convey the workpiece at the predetermined feed speed when the cam is in the feed range. According to the linkage control method, the sharpness of the file cuts of a product can be effectively improved and the service life of the product is effectively prolonged. The invention also discloses the file. During production of the file, the file and the feeding mechanism are controlled by using the linkage control method.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and more specifically relates to a linkage control method of a chopping knife and a feeding mechanism in processing files and file patterns. Background technique [0002] At present, the processing of the file pattern on the file is generally processed by the method of mechanical profiling. In this processing method of mechanical profiling, the chopping knife 02 and the feeding mechanism are relatively independent, and the chopping knife 02 is only based on the feeding speed of the feeding mechanism. Determine the tooth chopping rhythm in order to control the tooth mark spacing on the file. The feeding mode of the feeding mechanism is continuous feeding, that is, when the chopping knife cuts into the workpiece 01, the workpiece 01 is still sent forward by the feeding mechanism. [0003] In this continuous feeding mode, during the whole process from the chopping knife 02 cutting into...

Problems solved by technology

[0003] In this continuous feeding mode, during the whole process from the chopping knife 02 cutting into the surface of the workpiece 01 to the chopping knife 02 leaving the surface of the workpiece 01, there is always a relative movement in the horizontal direction between the workpiece 01 and the chopping knife 02, which leads to the chopping knife 02 There is a force opposite to the movement direction of the workpiece 01 on the workpiece 01, which causes the rake angle of the file pattern to become larger, and the main file pattern is convex, such as figure 1 The front angle of the auxiliary file pattern 03 has become larger, figure 2 The middle part of the main file pattern 04 is arc-shaped, which will lead to the problems of insufficient sharpness and short product life in subsequent products
