Steel structural system circular tube compression bar and machining device and method thereof

Abstract

The invention relates to a machining device for a steel structural system circular tube compression bar and a circular tube compressor bar machined by the device and belongs to the technical field of building steel structures. The machining device for the steel structural system circular tube compression bar comprises a support, a motor, a feeding table and a flattening mold, wherein the feeding table is driven by the motor to drive the circular tube compressor bar to move left and right on the support, the flattening mold is located on one side of the support, a conical feeding port is formed in the end, facing toward the feeding table, of the flattening mold, and the machining method includes the three steps of feeding, end portion forming and discharging. According to the technical scheme, the technological process for manufacturing the circular tube compressor bar is simplified, machining and manufacturing efficiency is substantially improved, and manpower is saved; human product defects caused by slotting, welding and the like in the conventional circular tube compression bar manufacturing process are avoided; in the machining process, other accessories such as an end plate are not needed; a hole is formed in a circular tube after the circular tube is pressed at a time; the circular tube compression bar is attractive in appearance and convenient to install.

Description

technical field [0001] The invention relates to a circular pipe compression rod used as a support and a tie rod in a steel structure system and a processing method thereof, belonging to the field of building steel structures. Background technique [0002] As the main force-bearing and force-transmitting components, supports and tie rods have become an important part of the steel structure system. At present, the commonly used supports in the process of steel structure design include angle steel, round steel, H-shaped steel, round tube and other cross-section forms. The support is widely used because of its large lateral rigidity, beautiful shape, convenient processing, production and installation. At present, the processing methods of steel structure manufacturing and processing enterprises for the connection structure of the end of the rigid tie rod of the round pipe are: groove the end of the round pipe, insert a steel plate to weld to form a connecting plate, open a bolt ...

AI Technical Summary

Problems solved by technology

[0003] In order to improve the current situation of complex manufacturing process and low production efficiency of the existing rigid tie rods with round pipe cross sections, the present invention provides a new type-connected round pipe pressure rod at the end and a processing method for the end of the round pipe pressure rod. The processing method On the basis of ensuring the mechanical properties of the rigid tie rod of the round tube, the production process is simplified, the production efficiency is improved, and the plate is saved
