Steel plate bending device for lap joint of steel structure parts

Abstract

The invention provides a steel plate bending device for steel structure part lap joint, and belongs to the technical field of steel component machining equipment. The steel plate bending device for lap joint of the steel structure parts comprises a bending workbench, two brake air cylinders, a punch driving air cylinder, a bending punch and a servo motor; a steel plate bending groove is formed in the bending workbench, and fixed mounting boxes are fixedly connected to the front side wall and the rear side wall of the bending workbench correspondingly; and adjusting threaded rods are arranged in the two fixed mounting boxes. Two adjustable supports which are arranged on the outer surfaces of two sections of threads of the adjusting threaded rods in a threaded sleeving manner can do movement in opposite directions, the movement is synchronous, the controllability of the movement distance is high due to lead screw transmission, the distance between the two adjustable supports can be accurately and synchronously controlled, in other words, when the bending angle needs to be adjusted, the distance between the two adjusting supports can be adjusted and controlled, and compared with a traditional adjusting manner, controllability is better achieved.

Description

technical field [0001] The invention belongs to the technical field of steel component processing equipment, in particular to a steel plate bending device for lap joints of steel structure parts. Background technique [0002] The steel plate is a flat steel material that is poured with molten steel and pressed after cooling. It is flat and rectangular, and can be directly rolled or cut from a wide steel strip. The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm, the thin plates are classified by steel types, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates, etc.; by professional use, there are Plates for oil drums, plates for enamel, plates for bulletproof, etc.; according to the surface coating, there are galvanized sheets, tinned sheets, lead-plated sheets, plastic composite steel sheets, etc. When ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a steel plate bending device for lap joints of steel structure parts, which solves the problem that the existing equipment adopts one-time setting when bending the steel plate, due to the residual stress at the bending place of the steel plate. Existence, the phenomenon of springback is easy to appear, that is, the effect of bending cannot be guaranteed, and the problem of affecting use
