Precise and automatic cutting device and method for Teflon pipe

Abstract

The invention provides a precise and automatic cutting device for a Teflon pipe. The precise and automatic cutting device comprises a base, a cooling water tank, a conveying mechanism, a clamping mechanism, a cutting mechanism, a cutting driving mechanism, a support frame, a U-shaped pipe length compensation mechanism and a rack, wherein the U-shaped Teflon pipe penetrates through the cooling water tank to be inserted into the conveying mechanism; the Teflon pipe with a fixed length is conveyed into the clamping mechanism to be clamped by the conveying mechanism; the cutting driving mechanism drives the cutting mechanism to cut the Teflon pipe in the clamping mechanism; and the U-shaped pipe length compensation mechanism drives the base to move upwards or downwards to compensate the length of the Teflon pipe which is inserted into the cooling water tank. The invention further discloses a precise and automatic cutting method for the Teflon pipe. The precise and automatic cutting method comprises the following method of A, preparing; B, inserting; C, compensating; D, conveying for clamping and outputting; E, rotating; F, cutting and resetting; G releasing; H re-conveying, ejecting-out, re-outputting and re-clamping; and returning to the step F for cutting repeatedly. By adopting the precise and automatic cutting device and method, the length precision of the cut pipes can be effectively improved; and phenomena of pipe bending or flattening are reduced or even eradicated.

Description

technical field [0001] The invention relates to the technical field of industrial machinery automation, in particular to a precision automatic cutting equipment and 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 manuall...

AI Technical Summary

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
