Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to an automatic positioning device for cutting steel bars. Background Art

[0002] Steel bars need to be cut into different lengths during the processing. The existing steel bar cutting requires frequent manual placement and fixing before cutting. Accurate length cutting cannot be achieved during the cutting process, the labor intensity of the workers is relatively high, and it is easy to get into danger if they are close to the cutting equipment.

[0003] Chinese patent CN217192996U discloses a fixed-length cutting device for PC steel bar processing. This device realizes the fixed-length cutting of steel bars, but has the following disadvantages during use: first, the steel bars need to be pushed manually for cutting, and the cutting operation cannot be completed automatically; second, after the steel bars are cut, the fixed-length push plate of the device will block the material, which is not convenient for unloading the steel bars after cutting.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] During the implementation of the utility model, the positioning mechanism is first debugged to meet the positioning and cutting length of the steel bar, and then the steel plate is conveyed to the positioning mechanism by a roller conveyor belt. When the steel bar is completely positioned, the cutting equipment operates and cuts the steel bar below it. The entire steel bar cutting operation is performed automatically. After each section of the steel bar is cut, the limiting component in the positioning mechanism no longer limits the steel bar. At this time, the cut steel bar can be automatically dropped, and then the limiting component returns to its original state and completes the fixed-length limiting operation of the steel bar on the roller conveyor belt until the steel bar is completely cut.
