Bending angle adjusting structure and method for steel in production of fire-resisting window

Abstract

The invention discloses a bending angle adjusting structure and method for steel in production of a fire-resisting window, and relates to the technical field of production of fire-resisting windows. The structure comprises bottom bending assemblies, a supporting plate, limiting mechanisms, a moving mechanism and a top bending assembly, the top bending assembly is fixed to a piston rod of an air cylinder, a cylinder body of the air cylinder is fixed to a top frame, the top frame is fixed to the upper portion of a workbench, the two symmetrically-distributed bottom bending assemblies are arranged below the top bending assembly, the bottom bending assemblies are fixed to the top of the workbench, and the supporting plate is arranged at one sides of the upper portions of the bottom bending assemblies. According to the structure, the angle of V-shaped grooves of the bottom bending assemblies and the angle of a V-shaped protrusion of the top bending assembly can be freely adjusted so that the structure can bend steel with different angles, and in the bending process of the steel, the steel can be limited through the limiting mechanisms, and the limiting mechanisms can be adjusted through the moving mechanism so that the problem that the angle of the conventional steel bending angle structure is difficult to adjust is solved.

Description

technical field [0001] The invention belongs to the technical field of fireproof window production, and in particular relates to a structure and method for adjusting the bending angle of steel in the production of fireproof windows. Background technique [0002] Fire-resistant windows refer to windows that, together with the frame, can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. On the outer walls of two buildings with insufficient fire separation distances, or between spaces separated by firewalls, lighting and ventilation are required. When the fireproof window is used, the steel needs to be bent by the bending equipment in the production of the fireproof window. [0003] After retrieval, the announcement number CN112275854A, announcement date 2021.01.29 discloses a steel bending equipment for steel processing, which relates to the field of steel processing. The steel bending equipment for steel processin...

AI Technical Summary

Problems solved by technology

[0005] 1. The bending angle of the steel bending equipment is difficult to adjust, and the applicable surface is low;

[0006] 2. During the steel bending process of the steel bending equipment, the steel is easy to shift, resulting in the failure of the bending

[0007] Therefore, the existing steel bending equipment cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems
