Description

Technical Field

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

[0002] A rebar cutting device is a tool specifically used to cut rebars. It can quickly and accurately cut rebars into the required length. Rebar cutting machines are usually driven by electricity or hydraulics, and have the characteristics of high efficiency, safety, and energy saving. In construction projects, rebar cutting machines are widely used in rebar processing, concrete structure demolition, rebar welding, and other links.

[0003] For example, the Chinese patent application number is CN202222666964.2, which discloses a steel bar cutting device for construction engineering, including a main body and a storage box. After the horizontal frame is slid to the lower end of the steel bar, the guide plate is pushed to make it against one end of the steel bar. At this time, the cut steel bar is guided by the inclined surface of the top plate and slides into the interior of the storage box, and is stored on the inner side of the storage box guided by the top plate. As the pressure increases, the connecting rod can rotate, driving the top plate to gradually reset and restore the storage space. The simple structure can effectively prevent the steel bars from scattering everywhere, and can be transported without sorting to improve subsequent work efficiency; the positioning plate can be pushed outward by pushing the steel bar in, thereby driving the measuring belt to extend outward. At this time, the extended length of the steel bar can be directly observed through the measuring belt. The operation is simple and does not require manual measurement of the length of the steel bar. The positioning plate can also be driven by the flat spiral spring to automatically reset for the next use.

[0004] However, in actual use, when multiple sections of steel bars need to be cut, manual feeding is required. The user manually moves the steel bars under the cutting disc continuously, which wastes manpower and affects work efficiency. At the same time, the equipment will generate sparks and debris during the cutting process, which will accidentally injure the user and also pose a fire risk. Utility Model Content
