Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a steel bar bending machine used for mining machinery processing. Background Art

[0002] The rebar bending machine is one of the rebar processing machines. It is used in a wide range of industries, often in the construction industry, mining machinery processing, road and bridge industries, etc. Its working principle is a horizontal working disc rotating on a vertical axis. The supporting pin is fixed on the machine tool, and the center pin and the bending pin are on the working disc. The rebar is placed horizontally between the supporting pin and the center pin, and the other side is usually held manually. Start the machine, and when the disc moves, the rebar will be bent.

[0003] When the steel bar is bent, the other end is often held by a person. However, when the steel bar is bent, the force is often very large, and there is often a certain risk in holding it manually. In addition, when the steel bar is bent, there is a certain possibility of breaking. Existing steel bar bending machines rarely have protective covers. Therefore, when the steel bar breaks, it will cause certain potential dangers to the people around it. For this reason, we propose a steel bar bending machine for mining machinery processing.
