Description

Technical Field

[0001] The utility model relates to the technical field of high-strength steel bar processing, in particular to a bending device for high-strength steel bar processing. Background Art

[0002] High-strength steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars. High-strength steel bars need to be bent using a bending device during use. For example, a steel bar bending device for use on construction sites with publication number CN216938144U includes a base plate, two symmetrically arranged vertical plates are fixedly connected to the base plate, a fixed plate is fixed to the base plate, a slide groove is provided inside the fixed plate, and a liftable pressure plate is slidably arranged inside the slide groove. The steel bar bending device for construction sites arranges the steel bars in two pipe grooves by arranging a pressure plate, a spring and a driving component, and then starts the motor to drive the cam to rotate. The cam drives the pressure plate to descend, so that the pressure groove of the pressure plate contacts the steel bar to achieve the bending purpose. When the cam rotates, the elastic force of the spring resets the pressure plate, so that the pressure plate and the steel bar can be separated, and the steel bar can be taken conveniently. The pipe groove and the pressure groove are arranged, and the structures of the pipe groove and the pressure groove are the same, both of which are arc-shaped, so as to match the structure of the steel bar, so that the steel bar can be conveniently bent and the bending effect is good. The angle of the steel bar bent each time is fixed, and the steel bar cannot be bent at different angles, resulting in a small scope of use and poor practicality. Utility Model Content
