Description

Technical Field

[0001] The invention relates to the technical field of steel processing, in particular to a cutting device for processing bridge steel truss steel. Background Art

[0002] Bridge steel truss is an important component commonly used in large-span bridge structures. It is formed by processing steel into a truss structure to form a beam structure with high strength and light weight. The steel truss is composed of many steel components (such as rods, nodes, etc.) connected by welding, bolting or riveting. During the processing of steel trusses, the steel needs to be cut to ensure that the steel meets the design requirements and can withstand the load and mechanical performance requirements of the structure.

[0003] The reference patent publication number is CN219967089U, which is a multi-station cutting device for steel processing. The prior art uses a pressing plate to press and fix the steel, and a cutting blade cuts the steel at the same time, thereby preventing the steel from deviating during the cutting process, resulting in the problem of steel being scrapped or the cutting blade being broken and splashed, thereby ensuring the processing yield while ensuring the safety of the workers, and there is no need for the workers to manually fix the steel, which reduces the difficulty of operation for the workers and saves processing time;

[0004] During the use of the above patent, after a section of steel is cut, it is necessary to manually feed the steel to continue cutting. The degree of automation is low, manual feeding is time-consuming and labor-intensive, the labor intensity is high, and the work efficiency is low. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cutting device for processing bridge steel trusses, which solves the problem that after a section of steel is cut, the steel needs to be manually fed and cut further, resulting in a low degree of automation, time-consuming and labor-intensive manual feeding, and high labor intensity.

The work difficulty is relatively low, and the cleaning efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
