An abrasive belt interface structure and its docking process

Abstract

The invention discloses an abrasive belt joint structure. The abrasive belt joint structure comprises a plurality of joint unit bodies, wherein the joint unit bodies are continuously arranged at the end part of a base body of an adhesive belt; each joint unit body comprises an equilateral triangle part, a square part and an isosceles trapezoid part which are sequentially arranged and connected from the tail end of the adhesive belt to the base body, and the sides of the equilateral triangle part, the sides of the square part and the equal sides of the isosceles trapezoid part are the equal. The invention provides a butting technology. The butting technology comprises the following steps of cutting, edge grinding, water washing for oil removal, glue preparation, glue coating, and edge pressing. The adhesive belt joint structure and the butting technology thereof have the advantages that the defect of poor tensile capability of triangle and sinusoid joint shape is overcome; by using dry glue, acetic ether and curing agent to prepare the glue to adhere the joint, the tensile capability of the adhesive belt joint area is strong, and the anti-shear capability is good.

[0002] As a flexible grinding tool, abrasive belts are widely used in machining, aerospace, automobile manufacturing, gemstone processing, glass and ceramics, etc., and have the reputation of "industrial teeth". The research on superhard material abrasive belts has been started, and many applied research results have been obtained. There are few domestic researches in this area. High-end abrasive belts mainly rely on imports. Superhard material abrasive belts have high efficiency and high efficiency. In the research field of superhard material abrasive belts, the research on the interface of the abrasive belt is very important. The strength of the interface of the abrasive belt directly determines the service life and grinding effect of the entire abrasive belt. A good interface The shape can enhance the interface strength of the abrasive belt, improve the service life of the abrasive belt, and have better grinding quality. The interface shape and interface technology of the abrasive belt mainly solve two problems. One is the resistance to longitudinal tension in the grinding process. The second is to have good lateral shear resistance to ensure that no lateral slippage occurs at the interface of the abrasive belt. The interface forms of the abrasive belt mainly include lap joints and butt joints. The most commonly used form is the butt joint. At present The shape of the abrasive belt interface is triangular and spiral. There is a great relationship between the tensile capacity of the abrasive belt interface and the interface shape of the abrasive belt. Based on the insufficient strength of the existing abrasive belt interface, a new abrasive belt interface was invented. At the same time, technical treatment is carried out at the interface of the abrasive belt to improve the interface strength of the abrasive belt
