Abstract

The utility model relates to an automatic disk cutter that bush rubber roll cutter used, its characterized in that: the material is high-speed steel W18Cr4V, and the surface of the material is coated with a Teflon low-friction coating; the cutting edge width of the cutter is 20mm, a single-face double-layer opening is used, the angle of the first layer cutting edge is 26 degrees +/-0.02 degrees, and the angle of the second layer cutting edge is 2.8 degrees +/-0.02 degrees. The utility model has the advantages that: the rubber roller can cut off the bushing of the rubber roller bushing and rubber in a chipless mode, hardness and toughness of the cutter are considered, and fluffing of the cut surface of the rubber roller is avoided.

Description

Disc cutter for automatic lining rubber roll cutting-off machine

Technical Field

The utility model is used for cutting off of spinning bush rubber roll material stick especially relates to a disc cutter that automatic bush rubber roll cutter used.

Background

The spinning rubber roller is a key device on spinning machinery, has direct and important influence on the quality of finished yarn, is a sharp knife for improving the spinning quality, and the advantage of the spinning quality of the bushing rubber roller is determined by various spinning factories. The lining rubber roller consists of an inner hollow lining (mostly aluminum or hard plastic) and an outer rubber, and the cutting process of the rubber needs chipless cutting, so that the chipless cutting process is also adopted when the lining is cut.

Disclosure of Invention

An object of the utility model is to above-mentioned problem, design a disc cutter that automatic bush rubber roll cutter used, it can carry out chipless to the bush and the rubber of bush rubber roll simultaneously and cut off.

The utility model adopts the technical scheme that: the utility model provides a disc cutter that automatic bush rubber roll cutter used which characterized in that: the material is high-speed steel W18Cr4V, and the surface of the material is coated with a Teflon low-friction coating; the cutting edge width of the cutter is 20mm, a single-face double-layer opening is used, the angle of the first layer cutting edge is 26 degrees +/-0.02 degrees, and the angle of the second layer cutting edge is 2.8 degrees +/-0.02 degrees.

The utility model has the advantages that: can carry out chipless to bush and the rubber of bush rubber roll simultaneously and cut off, compromise the hardness and the toughness of cutter, avoid the rubber roll cut surface fluff phenomenon.

Drawings

Fig. 2 is a sectional view of the cutting edge of the present invention.

Detailed Description

As shown in fig. 1 and 2, the utility model relates to a disc cutter for an automatic lining rubber roller cut-off machine, which is in a disc shape with an outer diameter of 105mm, a central hole diameter of 20mm and a thickness of 1.5mm, is made of high-speed steel W18Cr4V, and is coated with a Teflon low-friction coating on the surface; the cutting edge width of the cutter is 20mm, a single-face double-layer opening is used, the angle of the first layer cutting edge is 26 degrees +/-0.02 degrees, and the angle of the second layer cutting edge is 2.8 degrees +/-0.02 degrees.

The working process of the utility model is as follows:

as shown in fig. 1 and 2, when the bar rotates, the circular disc cutter cuts into the bar; the disc cutter can cut off rubber when the disc cutter is static, and when the disc cutter is cut to the lining, the disc cutter starts to rotate along with the lining, and the state just meets the chipless cutting-off process of the lining; after the disc cutter starts to rotate, the friction between the disc cutter and the cut surface of the rubber roll can be increased, and in order to avoid the fluffing phenomenon of the cut surface of the rubber roll, a Teflon low-friction coating is coated on the surface of the disc cutter.

The foregoing is illustrative of the preferred embodiments of the present invention and is not intended to limit the shape, materials, or configuration of the invention in any way. Any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should still fall within the scope of the present invention.

Claims
