Description

Technical Field

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

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. During construction, rebar is needed on construction sites. At the same time, when rebar is used, it needs to be cut into corresponding lengths to facilitate the arrangement and installation of the rebar. In order to facilitate the cutting of rebar, a shearing machine is needed to cut the rebar.

[0003] At present, the traditional steel bar shearing machine still has some shortcomings. Before shearing the steel bar, the steel bar is usually placed in a trough to limit and fix the steel bar. Since the size of the trough is fixed and the steel bars to be sheared are of different sizes and thicknesses, the trough cannot adapt to steel bars of different sizes, thereby reducing the practicality of the shearing machine. For this reason, we propose a mobile steel bar shearing machine. Utility Model Content

[0004] Based on the deficiencies in the prior art mentioned in the above background technology, the utility model provides a mobile steel bar shearing machine.

[0005] The utility model overcomes the above technical problems by adopting the following technical solutions, specifically:

[0010] As a further solution of the utility model: the adjustment mechanism includes a U-shaped frame, a guide wheel, an L-shaped frame and a handle, the U-shaped frame is connected to the top of the base plate, and a slide groove is provided at the bottom of the inner wall of the U-shaped frame, the guide wheel slides inside the slide groove, the L-shaped frame is connected to the top of the guide wheel, and the handle is connected to the back of the L-shaped frame.

The output shaft of the starter motor drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to drive the threaded rod to rotate, so that the threaded block descends and drives the two U-shaped plates to slide downward on the bottom plate through the two connecting plates.

The utility model can flexibly adjust the position of the shearing assembly to facilitate shearing at different positions of the steel bars and control the shearing length of the steel bars, thereby facilitating the staff to cut steel bars of different lengths.
