A kind of fast processing machine and processing method for steel structure section steel cutting fracture

Abstract

The invention belongs to the field of profile steel, and particularly relates to a quick treating machine for a cutting fracture of steel-structured profile steel and a treating method. The quick treating machine comprises a mounting plate; a first supporting frame and a second supporting frame are mounted at the top and the bottom of the mounting plate; sliding rods are arranged in the first supporting frame and the second supporting frame in a sliding fit manner; the end parts of the sliding rods are connected with a magnet plate; air passages are arranged in the mounting plate; a suction pump is mounted on the rear surface of the mounting plate; a first sliding rail and a second sliding rail are mounted on the front surface of the mounting plate; first sliding blocks are arranged on thefirst sliding rail in a sliding fit manner; second sliding blocks are arranged on the second sliding rail in a sliding fit manner; a third sliding rail is fixedly connected between the first slidingblocks and the second sliding blocks; third sliding blocks are arranged on the third sliding rail in a sliding fit manner; a driving belt wheel and a driven belt wheel are arranged on the third sliding rail in a sliding fit manner; and a polishing belt is arranged on the outer surfaces of the driving belt wheel and the driven belt wheel in a matching manner. The quick treating machine and the treating method can realize complete laminating polishing of common C-shaped steel and H-shaped steel in a steel structure, and improve the polishing effect; and abrasive dust generated in the polishing process cannot enter a part between the fracture of the profile steel and a polished surface.

Description

technical field [0001] The invention belongs to the technical field of steel structure processing, and in particular relates to a fast processing machine and processing method for steel structure section steel cutting fractures. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The steel structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and plate steel, and is treated with rust removal and antirust processes such as silanization, washing and drying, and galvanizing. The members or components in the steel structure are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size. According to the cross-sectional s...

Problems solved by technology

[0005] The present invention provides a machine and processing method for fast processing of section steel cutting fractures of steel structure, aiming to solve the following problems existing in the grinding of section steel cutting fractures by using the grinding device in the prior art: (1) only circular Grinding at the fracture of the steel, for the C-shaped steel and H-shaped steel commonly used in the steel structure, can not be completely fitted and polished; (2) The grinding debris generated during the grinding process splashes into the gap between the steel fracture and the grinding surface, which seriously reduces the grinding effect. the quality of
