Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting machines, in particular to a steel bar cutting machine for construction engineering. Background Art

[0002] A steel bar cutting machine is a tool used to cut steel bars. It can be divided into fully automatic steel bar cutting machines and semi-automatic steel bar cutting machines. It is mainly used to cut steel bars to a fixed length in civil engineering projects and is an indispensable equipment in the steel bar processing link. Compared with other cutting equipment, it has the advantages of light weight, low energy consumption, reliable operation, and high efficiency. Therefore, it has been widely used in the field of mechanical processing and has played an important role in the process of national economic construction.

[0003] Rebar is widely used in construction. It can be used as prefabricated components, reinforced concrete and stirrups, etc. For this purpose, a rebar cutting machine is needed to cut the rebar according to the required length. However, the current rebar cutting machine requires manual labor to hold the rebar and wait for the cutter to cut the rebar before continuing to push the rebar deeper inside. The rebar has rebound stress at the moment of cutting, which will cause vibration to the workers' hands. Manually holding the rebar also increases the labor of the workers. Utility Model Content

One end of the movable rod 5 is fixedly connected to a fixed plate 6, and the other end of the movable rod 5 is fixedly connected to a movable block 7. A spring 8 is sleeved on the surface of the movable rod 5, and the two ends of the spring 8 are respectively fixed to the inner wall of the support plate 4 and the movable block 7. The top of the movable block 7 is fixedly connected to a limiting plate 9, and a buffer pad 17 is arranged on the inner side of the limiting plate 9. The buffer pad 17 is made of rubber, which can increase the friction between the limiting plate 9 and the surface of the steel bar and reduce the amplitude of the swing.

The crank 131 is arranged on the surface of the mounting plate 10, the back of the crank 131 is fixed to one end of the worm 132, one side of the worm wheel 133 is fixed to the other end of the rotating rod 11, and the bottom of the worm wheel 133 is meshed with the top of the worm 132. In this way, when the rotating rod 11 is driven to rotate, the crank 131 can be rotated, and the worm 132 can be driven to rotate, and at the same time, the worm wheel 133 can be driven to rotate, thereby driving the rotating rod 11 to rotate.
