Steel pipe truss production line

Abstract

The invention discloses a steel pipe truss production line which comprises a rack. A steel pipe support is installed on the rack. Multiple steel pipe riding wheels are installed on the steel pipe support. Steel bar guide grooves are formed in the two sides of the length direction of the steel pipe support. A steel bar bending forming device is arranged at one end of the steel pipe support, and a first sliding block is arranged on the side, away from the steel pipe support, of the steel bar bending forming device. The first sliding block is connected with a piston rod of a steel bar feeding aircylinder and can move in the length direction of the rack under the drive of the steel bar feeding air cylinder. A first double-head pneumatic steel bar clamp is installed on the first sliding block,and a movable frame is installed on the rack. The movable frame is connected with a piston rod of a steel pipe driving air cylinder and can move in a reciprocating manner in the length direction of the rack under drive of the steel pipe driving air cylinder. A transverse moving frame is installed on the movable frame, and a downward pressing air cylinder is installed on the transverse moving frame. By means of the steel pipe truss production line, a steel pipe can be automatically welded to the two sides of the bending position of a steel bar, the production efficiency is high, and the lack welding rate is low; and continuous feeding and automatic unloading can be achieved, and continuous efficient production is facilitated.

Description

technical field [0001] The invention relates to a steel pipe truss production equipment, in particular to a steel pipe truss production line. Background technique [0002] Prefabricated components of prefabricated buildings have been widely used in various building constructions such as residences, office buildings, and apartments in recent years. In order to improve the strength of prefabricated components, those skilled in the art have designed prefabricated components that are prefabricated with concrete components and steel trusses. This The trusses used in this kind of prefabricated components are mostly formed by welding the two sides of an upper chord steel bar with two bent steel bars at first. Because the steel pipe structure can further improve the load-bearing and compressive capacity of the truss, steel pipe truss products have begun to appear this year.

[0002] Prefabricated components of prefabricated buildings have been widely used in various building constructions such as residences, office buildings, and apartments in recent years. In order to improve the strength of prefabricated components, those skilled in the art have designed prefabricated components that are prefabricated with concrete components and steel trusses. This The trusses used in this kind of prefabricated components are mostly formed by welding the two sides of an upper chord steel bar with two bent steel bars at first. Because the steel pipe structure can further improve the load-bearing and compressive capacity of the truss, steel pipe truss products have begun to appear this year. This product welds bent steel bars on both sides of the steel pipe to form a truss structure, which effectively improves the load-bearing and compressive capacity. Since the welding position of the steel pipe and the steel bar is located at the arc top of the steel bar bend, when the steel bar provides support to the steel pipe, the steel bar bend will lose a part of the support force, so there is still room for improvement in the performance of the steel pipe truss. The upper ends of the straight steel bars on both sides of the bend of the steel bar are welded to the steel pipe, which can effectively increase the support force of the steel bar to the steel pipe. However, the existing truss production line cannot complete this welding, so this truss does not yet have mechanized production conditions.
