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 fixed-length cutting. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. In the process of using steel bars, in order to meet the length requirements of the staff, they are usually cut, so a cutting machine is needed;

[0003] However, when using the existing cutting machine, the steel bar is usually placed on the cutting table, and then the cutting machine is started to cut the steel bar to complete the steel bar cutting work. However, in actual use, in order to obtain the steel bar of accurate length, the staff usually measures the steel bar with a measuring tape before cutting. After the measurement, take out a marker to make a mark on the surface of the measuring point, and then cut it. This increases the workload of the staff and also wastes the staff's savings. For this reason, we propose a steel bar cutting machine for fixed-length cutting. Utility Model Content
