Machining machine and machining process for manufacturing steel pipe structure of steel pipe truss

Abstract

The invention provides a machining machine and a machining process for manufacturing a steel pipe structure of a steel pipe truss. The machining machine comprises a workbench, a supporting and limiting device and a bending device. According to the device, the following problems existing in the machining process of manufacturing the steel pipe structure of the steel pipe truss can be solved of a, bending machining can only be carried out for a certain size when traditional steel pipes are bent at present, bending machining cannot be carried out on the steel pipes of various sizes, meanwhile when traditional bending equipment is used for bending the steel pipes, steel pipes with different angles cannot be machined, only one bending angle can be achieved, the function is single, and the effect is limited; and b, when the existing bending equipment is used for bending, the bending part of the steel pipe is sunken and deformed, repairing is often needed, time and labor are wasted, even some steel pipes are directly scrapped, the cost is increased, meanwhile, certain resilience exists after the steel pipe is bent, so that the bending angle of the finally formed steel pipe does not meet the requirement, and the steel pipe needs to be processed again.

Description

technical field

[0001] The invention relates to the technical field of steel pipe truss production, in particular to a steel pipe truss production steel pipe structure processing machine and processing technology. Background technique

[0002] A truss is a structure made up of members connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure of triangular units. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with solid web beams, reduce self-weight and Increase stiffness. The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials, and reduce structural weight. Commonly used are steel truss, reinforced concrete truss, prestressed concrete truss, wooden truss, steel and wood composite truss, steel...
