Processing and grinding device for rectangular steel bar

Abstract

The invention discloses a processing and grinding device for a rectangular steel bar. The processing and grinding device comprises a grinding rack which is composed of a base and a supporting framework, wherein a grinding cavity is arranged in the supporting framework; one side, close to the base, of the left side end surface of the supporting framework is provided a through slot; a protruding part is fixedly arranged at the position, opposite to the right side of the through slot, on the inner wall of the right side of the grinding cavity; the top edge of the left side of the protruding partis equipped with an opening slot which is formed in the front-rear extending mode; a tapered tooth-shaped bar which extends in the front-rear extending direction of the opening slot is fixedly arranged on the inner wall of the right side of the opening slot; the top end surface of one side, away from the opening slot, of the protruding part is equipped with a first threaded rod which is arranged in an upward extending mode; the first threaded rod is connected with a lifting bracket in a threaded fit mode, wherein the right side end surface of the lifting bracket is connected with the inner wall of the right side of the grinding cavity in a resisting and sliding-fit mode; first baffle plates are symmetrically arranged at front and rear sides of the lifting bracket; guide rods are arranged between the first baffle plates at front and rear sides in an up-and-down symmetrical manner, and a grinding performing mechanism which extends towards the left side is connected on the two groups of the guide rods in the sliding-fit mode. The processing and grinding device is simple in structure, improves grinding efficiency and quality, and is high in grinding safety.

Description

technical field [0001] The invention relates to the technical field of industrial production and processing equipment, in particular to a processing and grinding device for rectangular steel bars. Background technique [0002] Steel bars are characterized by light weight, high pressure resistance, good toughness, fast construction, and long life. They are widely used in municipal drainage and sewage, agricultural irrigation, coal mine ventilation, chemical industry, and communication cable sheathing. The surface is rusted, and the rusted steel strip cannot meet the production process requirements. Therefore, it is necessary to polish the surface of the steel strip to remove surface rust. There are a lot of equipment for treating the surface of steel strips. At present, the common grinding device structure is generally arranged along the length direction, that is, a friction wheel is set on a frame, and the steel strip passes through the friction wheel for friction work.

Problems solved by technology

This kind of device usually can't carry out the grinding operation well, and can't achieve better grinding effect. In order to achieve better grinding effect, the steel strip is generally repeatedly polished. The above-mentioned method is time-consuming and labor-intensive, increases labor costs, and poor vacuuming
