Abrasion homogenizing method for pin roller surface

Abstract

The invention provides an abrasion homogenizing method for a pin roller surface. The method comprises steps as follows: (1) abrasion data are measured as follows: current abrasion situation data of the roller surface are calculated; (2) the homogenizing quantity is calculated as follows: according to the current abrasion situation data and the optimal working size, the total homogenizing quantityrequired to be homogenized is calculated; (3) quick machining is performed as follows: according to the total homogenizing quantity, the roller surface is machined to be close to the optimal working size through quick machining, and partial to-be-homogenized part is reserved; (4) trimming machining is performed as follows: the to-be-homogenized part reserved in the step (3) is trimmed to the optimal working size through trimming forming; (5) the abrasion data are verified as follows: the abrasion data are measured so as to verify whether the optimal working size is realized. With the method, the processing time for abrasion homogenization of the pin roller surface can be shortened, accurate control on the roller surface size and shape can be enhanced, and meanwhile, the use amount of grinding pieces and the change workload can be reduced; and the problem of abrasion inconsistency of the pin roller surface in the roller width direction is solved, and the working efficiency of a roller press is improved.

Description

technical field [0001] The invention belongs to the field of equipment wear and repair, and in particular relates to a wear homogenization method for a stud roller surface. Background technique [0002] Roller presses are widely used in building materials, cement, metallurgical mines, chemicals and other fields. They have the advantages of high efficiency, energy saving, and environmental protection. The method of inlaying carbide studs is adopted to ensure the wear resistance of the roller surface. The working principle of the roller press: it consists of two rollers, the material is fed from the middle of the two rollers, and the pressure is applied to the material through the relative rotation of the two rollers. The crushed material is squeezed to form a dense material bed, and enters the next process from the bottom of the two rollers. In the process, after a period of normal operation, due to the high abrasiveness of the grinding materials, the surface of the stud rol...

Problems solved by technology

The working principle of the roller press: it consists of two rollers, the material is fed from the middle of the two rollers, and the pressure is applied to the material through the relative rotation of the two rollers. The crushed material is squeezed to form a dense material bed, and enters the next process from the bottom of the two rollers. In the process, after a period of normal operation, due to the high abrasiveness of the grinding materials, the surface of the stud roller will be worn to varying degrees, and the edge effect will cause the middle part of the roller surface to wear more and the edge to wear less. The distance between the two rollers in the width direction is inconsistent, and in serious cases, the material in the middle part will directly enter the next process without being squeezed. The above situation makes the stud roller surface of the roller press still have a long working life. Efficiency drops sharply

[0003] The stud roller surface of the roller press is different from the traditional surfacing roller surface. The surfacing roller surface is surfacing a certain thickness of wear-resistant layer on the surface of the roller surface. After wear and tear, it can be repaired many times to return to the original size; and The stud roll surface is a cylindrical cemented carbide stud of a certain length embedded in the cylindrical hole of the base material of the roll surface. The studs are exposed to the roll surface. After the studs and the base material of the roll surface are worn, they cannot be repaired.
