Description

Technical Field

[0001] The utility model specifically relates to a steel bar bending shearing machine, belonging to the technical field of steel bar processing equipment. Background Art

[0002] With the continuous development of construction projects, steel bars, as the skeleton of concrete, are widely used in various building structures. They are also the main materials used in construction projects in large quantities. Before pouring concrete, the steel bars must be made into skeletons of certain specifications and forms before they can be included in the formwork. In the process of making the steel bar skeleton, the steel bars need to be bent and sheared before they can be bundled into shape. Therefore, a steel bar bending and shearing machine is needed to process the steel bars for subsequent use.

[0003] Common rebar bending and shearing machines can bend and shear rebars during use, but when continuously bending multiple groups of long rebars, workers are required to provide manual support to prevent one end of the rebar from tilting up and partially deforming during the bending process. During the support process, the rebar may injure the workers, which is less safe. Moreover, when the rebar is bent, the paint on the side of the rebar will fall off and produce debris. The debris falls on the turntable and blocks the bending slot, affecting the bending effect of the rebar. Generally, the workers have to clean it manually, which is inconvenient.
