A cutter cutter for cutting high-strength fabrics

Abstract

The invention relates to a cutting knife for cutting high-strength shell fabric. The cutting knife comprises a left flange plate and a right flange plate, symmetric annular step grooves are formed in outer edges of opposite surfaces of the left flange plate and the right flange plate, annular blades are installed inside the symmetric annular step grooves in a clamped mode, the annular step grooves and the annular blades are provided with pin holes in corresponding positions, pins are installed inside the pin holes, shaft holes are formed in the center of the left flange plate and the center of the right flange plate respectively, key grooves are formed inside the shaft holes, and the shaft holes and the key grooves are connected to a drive shaft with a connecting key. The annular blades are composed of base bodies and surface composite hard coatings. The cutting knife has the advantages of being relatively simple in structure, capable of being used for cutting various kinds of hard cloth, high in cutting efficiency and safe and reliable to use. Because polycrystalline cubic boron nitride or polycrystalline diamond is adopted as raw material of the base bodies of the annular blades and pseudo-alloy AB combination layers are arranged on the base bodies, the binding force between the base bodies and functional layers is increased, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of cloth cutting tools, in particular to a cutting tool for cutting high-strength fabrics. Background technique [0002] At present, in some leather cutting, cloth cutting and other industries, materials are often cut according to the needs of production, and modern people have higher and higher requirements for cutting technology, and high-speed efficiency is also required while pursuing high-quality cutting. For example, cutting out different shapes, different angles, and different lengths of cloth or leather requires manual cutting by workers in many cases. It is difficult to guarantee the quality of cutting, and the efficiency is relatively low. Therefore, in order to overcome this defect, the cutting machine was born And born. [0003] As a precision instrument for cutting materials such as cloth and leather, the cutting machine has been widely used in some leather and cloth industries due to its high ...

AI Technical Summary

Problems solved by technology

[0004] But at present, whether it is an ordinary cutting machine or a CNC cutting machine, it is impossible to cut aerospace and aerospace materials, such as carbon fiber boards or glass fiber boards. The main reason is that the cutting tools cannot achieve cutting hard strength of the material

However, if a machined tool is used to cut a carbon fiber plate or a glass fiber plate, a large amount of debris will be generated when the carbon fiber and glass fiber plate are cut, and most of the debris is in the form of powder. Generally, there is no special chip removal mechanism on the board, so that when the plate is being cut, the chips will also be taken out with the rotation of the tool, and then permeate the air, which not only affects the environment, but more importantly, due to the dust All have conductive properties, which can easily affect the electrical properties of the cutting equipment itself
