Production Description
The cold bending of the horizontal type I-steel bending machine of NC province is a metal processing production process of bending at normal temperature. In order to prevent deformation of the tube material during bending, a special bending device cold bending machine is required, where in the square tube cold bending process is the most complicated.
Working Principle
The cold bending performance index of the steel of the I-beam cold bending machine is expressed by the degree of bending that the test piece can withstand at normal temperature, and the degree of bending is distinguished by the ratio of the bending angle of the test piece and the thickness of the bending core to the thickness of the test piece.
The larger the bending angle of the test piece, the smaller the ratio of the diameter of the core to the thickness of the test piece, indicating that the requirement for cold bending performance is higher.
The bending of the cold-formed test piece will produce uneven plastic deformation, which can reveal to some extent whether the steel has defects such as uneven internal structure, internal stress, inclusions, unfused and micro-cracks.
Therefore, the cold bending performance of the I-beam cold bending machine can reflect the smelting quality and welding quality of the steel.
Product Features and Application
By using the digital encoder programming, the hydraulic control system can be positioned accurately and the bent steel section can be formed in one time. High efficiency, convenient operation, widely used in tunnel, subway, hydropower station and other industries, is the ideal equipment for steel arch manufacturing. Bendable steel sections include: I-beam, H-beam, channel steel, U-beam, etc.
Structure Composition and Advantages of I-beam Cold Bending Machine
Mechanical structure composition: it adopts the self-developed and designed turbine reducer drive, which is durable and powerful. During the bending process, the wheel mold rotates, and the high-strength strip pressing is used to shape the elbow at one time.
Circuit control part: it adopts the advanced embedded microcomputer intelligent control system to control, angle input to realize digitization, easy to use.
