Thermal cutting shear and cutting method thereof

Abstract

The invention relates to a thermal cutting shear and a cutting method thereof, and a flat arrangement type heating mode in fixture bodies is adopted to enhance the heating efficiency and the heat transfer speed and effectively control the operating temperature when the front end of a cutting edge carries out the cutting so as to enhance the cutting quality of the rubber material, and the quality of the joint and the stitching among various materials. The cutting shear comprises a group of the fixture bodies and shear bodies clamped and fixed among the fixture bodies, wherein at least one flat plate type heating plate is lined among the fixture bodies and the bases of the shear bodies; a heat source temperature sensor is arranged in the heating plate and is connected with an external power supply and a temperature control meter through a power supply wire; and a shear body temperature sensor is arranged in the cutting edge part of the shear bodies.

Description

technical field [0001] The invention provides a thermal cutter and a cutting method thereof for cutting a rubber compound layer, which are specifically applied to the manufacturing and processing process of common carrier tires and belong to the field of rubber machinery. Background technique [0002] Due to the popularization and use of aircraft, civil vehicles and other carriers, the level of automation and precision processing of tire manufacturing has been continuously improved. When cutting coil semi-finished products such as inner liner, sidewall or inner liner-sidewall composite parts, automatic cutting equipment is usually required to cut semi-finished products of different sizes and angles for subsequent joints, pressing, etc. In the process of use, the quality of rubber material cutting directly affects the joint and pressing between multiple materials. [0003] The cutting knives used in the existing automatic cutting equipment mainly include ultrasonic cutting k...

AI Technical Summary

Problems solved by technology

The control of the heating temperature of the knife body is actually based on the temperature test data of the base of the cutting knife, so the temperature at the front end of the knife edge when cutting deviates from the control range of the entire cutting equipment

[0008] In addition, the installation structure of the existing thermal cutter device is relatively complicated. When disassembling the cutter body, the entire clamp body needs to be disassembled from the mounting bracket. The installation and disassembly are time-consuming and laborious, and the production and processing efficiency is low.
