Automatic cold bending machine

Abstract

The invention discloses an automatic cold bending machine, comprising: a base; a pair of pressing roller assemblies, including a pair of pressing roller shafts, an upper pressing roller, a lower pressing roller, and a pressing roller motor; a pair of driving roller assemblies, the driving roller The components include horizontal rollers, vertical rollers, linkage structures, vertical roller motors, scissor-type hydraulic lifting frames; top roller assemblies, which include oil cylinders, top roller frames, and top rollers; consoles; Direction, a pressing roller assembly, a driving roller assembly, a top roller assembly, another driving roller assembly, and another pressing roller assembly are sequentially arranged on the base. The invention can realize the mechanized integrated operation of feeding, clamping, transmission and bending, is suitable for the bending operation of steel bars with complex shapes, has a high degree of automation, and promotes production efficiency.

Description

technical field [0001] The invention relates to the technical field of steel processing. More specifically, the present invention relates to an automatic cold bender. Background technique [0002] The cold bending machine is mainly used in the bending of I-beam, channel steel, angle steel, U-shaped steel and other profiles during the construction of tunnels, subways, hydropower stations, and underground caverns. In the process of tunnel construction, the steel arch frame is mainly used for the initial support of the tunnel, and the processing of the arch frame usually adopts the arch frame cold bending machine. The cold bending machine is composed of a base, a mechanical transmission system, a cold bending system, a hydraulic system, and an electrical control system. The existing cold bending machine has the following problems: first, the mechanical transmission system usually requires the staff to manually tighten a pair of lead screws for each roller structure, which is ...

AI Technical Summary

Problems solved by technology

The existing cold bending machine has the following problems: first, the mechanical transmission system usually requires the staff to manually tighten a pair of lead screws for each roller structure, which is time-consuming and laborious, and the adjustment of the upper roller may not be in place; second, The power is the driving roller on the side. The surface area of ​​the driving roller is large and the contact area is small. When the bending angle is large, it may cause insufficient power; third, the console is operated by buttons without digital control. When bending, you need to watch the button on the steel At the same time, the buttons are manipulated to bend accurately. Since the buttons are all inching type, the action will stop as soon as the finger leaves the button. The requirements for the staff are high. Compared with the processing of the arch frame, the technology is difficult, the process is cumbersome, and the manual workload is large.
