Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, in particular to an adjustable fixing mechanism of a steel bar cutting machine. Background Art

[0002] A steel bar cutter is a tool used to cut steel bars. It is generally divided into fully automatic steel bar cutters and semi-automatic steel bar cutters. It is one of the essential equipment for steel bar processing. It is mainly used for cutting steel bars to a fixed length in house construction, bridges, tunnels, power stations, large-scale water conservancy projects, etc. Compared with other cutting equipment, steel bar cutters have the characteristics of light weight, low energy consumption, reliable operation, and high efficiency.

[0003] Among them, after searching, it was found that the application number is CN202021014984.6. A fixed steel bar cutting device includes a second workbench, a switch is installed on the top of the second workbench, and a support table is installed on the side of the second workbench close to the switch. The top of the support table is rotatably connected to a mounting seat through a rotating shaft, and one end of the mounting seat is rotatably connected to a blade mounting disk through a rotating shaft, and a knife is installed inside the blade mounting disk. This new type has the effect of solving the problem that metal debris adheres to the blade under high temperature, which is not conducive to the reuse of the blade; Among them, the shortcomings are as follows:

[0004] After research and analysis, it was found that before cutting the steel bars, the device limits and fixes the steel bars by directly placing them into the limiting grooves, and clamps and fixes one side of the steel bars by rotating the rotating rod to push the movable rod. Since the top of the steel bars is clamped, it is easy for the steel bars to bounce up due to force during the cutting process, resulting in low efficiency in fixing the steel bars. In addition, after the device fixes the steel bars, it is difficult to push the steel bars to move, which requires loosening the clamping of the steel bars after cutting to move the steel bars again, which is not convenient for moving the steel bars. In addition, the device can drive the entire device to move by using universal wheels. However, after moving, since the universal wheels are difficult to lock, the device will still move due to force when it needs to stop. Utility Model Content

During this period, the slider 702 can be driven to move by rotating the screw rod 701, thereby driving the guide wheel 704 to move, so that the guide wheel 704 contacts the steel bar, and the steel bar can be moved under the guidance of the guide wheel 704 by pushing the steel bar, so as to facilitate the control of the cutting position.
