Description

Technical Field

[0001] The utility model relates to the technical field of steel bar shearing, in particular to a steel bar shearing device. Background Art

[0002] Rebar is an indispensable building material in the current construction market. After being formed and cooled, the rebar has a certain length. After cooling, it needs to be cut according to a certain size. At this time, a rebar shearing machine is needed. The demand for rebar shearing machine products is large in the domestic and foreign markets. There are many domestic manufacturers of similar products, and they are gradually forming serialization and scale. Most of the structures of rebar shearing machines are gear transmission. This type of shearing machine has a complex structure, high cost, and high strength requirements for the gear mechanism. Before the use of rebar, the required size varies due to different purposes. At present, the fixed-length cutting of rebars is mostly measured manually. After the length is measured, it is cut one by one. This cutting method requires that there are staff on site at all times. Not only does it waste a lot of manpower, but it is also easy to cause the cut rebar to be different in length from the same batch due to operational errors during measurement, which in turn causes waste. To this end, we provide a rebar shearing device to solve the above problems. Utility Model Content

At the same time, by clamping the driven roller and the active roller, the active roller is driven by the motor to convey the steel bars to the shearing assembly, which can facilitate the control of the shearing length of the steel bars and has certain practicality.
