Local heating cutting device with function of reducing abrasion of cutting knife for welding

Abstract

The invention discloses a local heating cutting device with a cutting knife abrasion reducing function for welding. The local heating cutting device comprises a fixing frame, a supporting plate, a cutting knife, a knife head, a knife shaft and a mounting head. The interior of the fixing frame is slidably connected with the supporting plate, the cutting knife, the knife head, the knife shaft and the mounting head are arranged between the supporting plate and the fixing frame, the cutting knife is fixedly inserted into one end of the knife head, the other end of the knife head is in threaded connection with one end of the knife shaft, and the other end of the knife shaft is fixedly inserted into the mounting head; the cutting knife comprises a blade, an end and a fixing piece, and the interior of a knife head is fixedly connected with the first heating piece and the second heating piece. The cutting tool has the beneficial effects that the interior of the tool bit is heated to achieve rapid heating of the cutting tool, abrasion consumption of the cutting tool can be reduced, the service life of the cutting tool is prolonged, the cutting tool is convenient to mount and dismount, rapid operation can be achieved during replacement, the stability of the cutting tool during mounting can be improved through cooperation of a fixing part and a limiting part, and the cutting tool is convenient to use. And the disassembly and assembly convenience is improved.

Description

Technical field [0001] The present invention particularly relates to a cutting device having a cutting blade to reduce the wear of welding local heating function, belonging to the technical field of thermal cutting. Background technique [0002] Cutting blade means used in the cutting blade, the blade is part of a tool, machine, or arms, which edge designed for piercing, cutting or scratching the surface of a material, such as a blade may be made of flint, metal, ceramic or other materials, blade is one of the oldest human tool, and has been used in combat, preparing food and other uses, toothed blade made of high quality materials, with a sharp, durable, rust and other features, has no flash cutting, long life, can lead to higher productivity for the machine, bag cutting tooth, lace appearance, easily torn, etc., it is mainly used for charter flights, charter feeding, bag-making machine with a cutter, with a blade sealing machine, with the tape blade, rotary press with a blade, ...

AI Technical Summary

Problems solved by technology

[0003] In the patent document "CN201510396286.4 A cutting head that can be used for electric heating", the cutting head that can use electricity to heat the cutting blade is installed on the cutting machine, and when the temperature of the cutting blade reaches a certain temperature, it will be heated again. When cutting materials with low melting point such as pearl cotton, sponge, foam, etc., the cutting resistance will be very small because the material will be melted during cutting, so the material can be cut quickly. In order to be suitable for cutting different materials, it is necessary to The temperature of the cutting blade is adjustable, and an adjustable potentiometer is set on the controller to adjust the temperature of the blade. It is suitable for cutting different materials, but it is difficult to realize the local heating function of the cutting blade, and a large amount of high temperature generated during cutting is easy to dissipate. , increase the burden of economic consumption, especially when it is used for a long time, it will cause power consumption. When cutting, it is difficult to quickly and locally heat the blade, which will reduce the service life of the cutting knife, and it is difficult to replace and install the blade. When cutting the knife, the operation is inconvenient, which affects the use effect

There is still no local heating cutting device for welding with a reasonable and reliable structure and the function of reducing the wear of the cutting knife and facilitating the replacement of the cutting knife.
