Polishing machine of steel belt edges

Abstract

A polishing machine of steel belt edges comprises a machine frame, a polishing ash gathering device and two polishing boxes. A steel belt through hole is arranged on a left lateral wall and a right lateral wall of each polishing box respectively, and a group of polishing devices are respectively arranged on installation platforms of the front side and the back side of each polishing box. Each polishing device comprises a base, polishing motors, a polishing wheel, a rocking plate, a rocking plate base, a polishing wheel position adjustment device and a bob-weight block. The middle portion of the rocking plate is hinged to the rocking plate base, the polishing wheel is connected with a polishing motor shaft through a connecting rod, and the polishing motor shaft is perpendicular to the moving direction of a steel belt. The two polishing motors are arranged on each polishing device, the two polishing motors are fixed on an upper plate face and a lower plate face at the left end and the right end of the rocking plate in a vertically-staggered mode, and the bob-weight block and the rocking plate are fixedly connected to one end of the rocking plate used for installing the polishing motors for polishing upper surfaces of the steel belt edges. A polishing wheel through hole for the polishing wheel to penetrate through is respectively arranged on a front lateral wall and a back lateral wall of each polishing box. The polishing machine relates to the field of manufacturing equipment of steel-plastic composite pipes, and the polishing machine has the advantages of being simple in structure, reliable in use and high in polishing uniformity.

Description

technical field [0001] The invention relates to the field of steel-plastic pipe manufacturing equipment, in particular to a steel strip edge grinder capable of simultaneously grinding the upper and lower surfaces of both side edges of a steel strip. Background technique [0002] The galvanized steel strip reinforced steel-plastic pipe with galvanized steel strip as the intermediate reinforcement layer is an important steel-plastic composite pipe. Advantages of steel and low cost. In the production of galvanized steel strip reinforced steel-plastic pipe, before the galvanized steel strip is crimped and butt-welded into the middle reinforced steel pipe layer, the galvanized layer on the edge of the galvanized steel strip needs to be removed by grinding. During grinding, the size and stability of the grinding force between the grinding wheel and the steel belt have an important influence on the grinding quality. The existing grinding equipment generally uses a manual mechanis...

AI Technical Summary

Problems solved by technology

The existing problems are: the electronic control adjustment needs to consume electric energy and has hysteresis, complex structure, high use and manufacturing costs, and poor work reliability; moreover, this patented solution can only achieve single-sided grinding of the strip. To achieve double-sided grinding, The size of the machine will be greatly increased, and the reliability of the machine will be further reduced.
