Steel bar straightening and cutting device for construction machinery

Abstract

The invention discloses a steel bar straightening and cutting device for construction machinery. The steel bar straightening and cutting device comprises a base plate, a motor mounting seat, an L-shaped mounting plate, a first motor, a shaft coupler, a threaded rod, a sliding locking seat, a first hydraulic cylinder, a first fixed plate, a T-shaped sliding rail, a machining mounting seat, a control module, a fixed column, a pressure sensor, a U-shaped mounting plate, a second hydraulic cylinder, a second fixed plate, a mounting upright post, a guide rail, a sliding mounting seat, a second motor, a cutting plate, a toothed guide rail, a gear and a third motor. The steel bar straightening and cutting device disclosed by the invention is novel in structure, scientific in design, simple in structure, free of manual intervention in the overall straightening and cutting operation, capable of saving time and effort and also high in work efficiency; meanwhile, the pressure sensor is arranged to prevent an overlarge tensile force so as not to stretch a steel bar too much and not to damage the equipment, so the service life of the equipment is prolonged and the equipment is safer and more reliable; and by arranging the first hydraulic cylinder and the second hydraulic cylinder, the steel bar can be fixed conveniently and quickly and is hard to loosen after being fixed.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a steel bar straightening and cutting device for construction machinery. Background technique [0002] At present, with the rapid development of the economy, the development of industry and cities, a large number of houses are required to be built. Steel bars are an indispensable material in construction. Before using steel bars, they need to be straightened and cut. At present, the steel bars on the market Straightening and cutting equipment is unscientific in design and complex in structure. The entire straightening and cutting operation requires manual intervention, which is time-consuming and laborious, and the work efficiency is low. There is no tension detection device, and the tension is easy to be too large, resulting in excessive stretching of the steel bar and damage to the equipment, resulting in equipment failure. The service life of the steel bar is reduced, and...
