Steel bar piercing and vertical cutting device for rectangular steel tube of fabricated building

Abstract

The invention relates to a steel bar piercing and vertical cutting device for a rectangular steel tube of a fabricated building. The steel bar piercing and vertical cutting device for the rectangularsteel tube of the fabricated building comprises longitudinal guide rails and rear moving supports, wherein support wheels are arranged on the bottom parts of the rear moving supports and are arrangedon the longitudinal guide rails in a rolling way; a horizontal guide rail is arranged on the front sides of the upper surfaces of the rear moving supports along a left-and-right direction; a base is slidably arranged on the horizontal guide rail; a left stand column and a right stand column are perpendicularly arranged on the left side and the right side on the base; a steel bar piercing guide plate is arranged between the left stand column and the right stand column through a lifting drive mechanism in an up-and-down sliding way, and is arranged perpendicularly; two upper and lower rows of steel bar piercing guide holes are formed in the steel bar piercing guide plate; and a horizontal-moving lifting type cutting mechanism is arranged on the top part of the steel bar piercing guide plate.The steel bar piercing and vertical cutting device for the rectangular steel tube of the fabricated building provided by the invention is novel in design, simple in structure, convenient to operate,low in artificial labor intensity and high in cutting efficiency, the cutting length dimension is regular, the mechanization and automation degrees are greatly improved, the manufacturing quality of the rectangular steel tube is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a rectangular steel pipe piercing vertical cutting device for prefabricated buildings. Background technique [0002] The steel-concrete composite pipes used in prefabricated buildings include rectangular steel pipes. The open ends of the rectangular steel pipes are respectively fixed with rectangular flange plates. Steel-concrete composite pipe is convenient for vertical alignment and positioning device. The steel-concrete composite pipe disclosed in the steel-concrete composite pipe is basically the same in structure after connecting the flange plates arranged at the upper and lower ends of the rectangular tubular structural steel plate. Rectangular steel pipes can use two channel steels with opposite openings. Rectangular flange plates are welded on both ends of the two channel steels to form a frame structure, and then the rectangular steel plates a...

AI Technical Summary

Problems solved by technology

Rectangular steel pipes can use two channel steels with opposite openings. Rectangular flange plates are welded on both ends of the two channel steels to form a frame structure, and then the rectangular steel plates are positioned and welded to the outer sides of the two channel steels, and the rectangular The connection seam between the steel plate and the rectangular flange plate is also welded; the rectangular steel plates on both sides of the rectangular steel pipe are correspondingly provided with round holes arranged in a rectangular array, and tie bars are inserted in the round holes. Since there are many round holes, After the tie bars are penetrated, they need to be cut one by one, and a section of tie bars must be reserved outside the rectangular steel plate. Manual cutting is not only labor-intensive and inefficient, but also cannot guarantee all the tie bars. Therefore, it is urgent to design a device for quickly cutting the tie bars
