Machining and polishing device of equidistant rectangular steel bar

Abstract

The invention discloses a machining and polishing device of an equidistant rectangular steel bar. The machining and grinding device comprises a polishing rack composed of a base and a supporting frame, the supporting frame is internally provided with a polishing cavity, a through groove is formed in the side, close to the base, of the left side end face of the supporting frame, a raised part is fixedly arranged at the portion, at the inner wall of the right side of the polishing cavity, opposite to the right side of the through groove, an opening groove extending front and back is formed in the edge of the top of the left side of the raised part, a conical rack extending in the front and back extending direction of the opening groove is fixedly arranged in the inner wall of the right sideof the opening groove, a first threaded rod extending upwards is arranged on the top face of the side, away from the opening groove, of the raised part and is in cooperative threaded connection with alifting bracket slidably and cooperatively connected with the inner wall of the right side of the polishing cavity in an abutting mode, first baffles are symmetrically arranged at the front side andthe rear side of the lifting bracket, guide rods are symmetrically arranged at the upper side and the lower side between the first baffles at the front side and the rear side, and polishing executingmechanisms extending to the left side are slidably and cooperatively connected to the two sets of guide rods. The machining and polishing device is simple in structure, improves the polishing efficiency and quality and is high in polishing 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 equidistant 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 fricti...

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
