Problems solved by technology

Since the feeding is carried out by pressing the thin tube with the roller, the contact surface is small, and the pressure is adjusted manually, which is difficult to control. The thin tube is hard and easy to be bent or flattened, or slipped and deviated, and the cutting length and accuracy are difficult to guarantee. The quality of the cut is poor, it is easy to cut into oblique cuts, and the smaller the diameter of the thin tube, the more difficult it is to feed the material. This kind of material waste caused by bending or flattening the tube is huge

Abstract

The invention provides a precision cutting method for a Teflon pipe. The precision cutting method comprises the following steps of A, preparing, B, conveying, C, cutting and D, outputting; in the stepA, the Teflon pipe (4) is pulled out of a Teflon pipe rotating disc and inserted into a conveying wheel conveying mechanism (21); in the step B, a conveying wheel driving mechanism (22) drives the conveying wheel conveying mechanism (21) to forward convey the Teflon pipe with a fixed length into the clamping mechanism (31); in the step C, a cutting driving mechanism (33) operates to drive a cutting mechanism (32) to operate to cut the Teflon pipe clamped in the clamping mechanism (31); in the step D, the conveying wheel driving mechanism (22) operates again to drive the conveying wheel conveying mechanism (21) to forward convey the Teflon pipe with the fixed length into the clamping mechanism (31) and to push forward the cut Teflon pipe into a collecting box (5); and the step C is returned, cutting and outputting are repeated. The length precision of the cut pipe can be effectively improved, the cutting quality is good, and the bending or flattening situation of the pipe is reduced oreven eliminated.

Description

technical field [0001] The invention relates to the technical field of industrial machinery automation, in particular to a precision cutting method for Teflon tubes. Background technique [0002] In the cutting operation of Teflon thin tubes, it is usually necessary to cut a variety of short tubes of specific lengths for one type of tube. smooth. [0003] At present, for cutting Teflon thin tubes of a specific length, the common way is to use rollers to feed the material, and then cut it with a blade. The method is to press a Teflon thin tube with a pair of rollers. The active roller rotates to apply frictional force to the thin tube, and feeds the material forward continuously. After passing through a specific mold, when the thin tube reaches the predetermined length, the cutter completes the cutting action. Since the feeding is carried out by pressing the thin tube with the roller, the contact surface is small, and the pressure is adjusted manually, which is difficult to...
