Cutting device for steel bar straightening machine

Abstract

The invention relates to the technical field of building material machinery, and discloses a cutting device for a steel bar straightening machine. The cutting device comprises a shell, one side of the shell is fixedly provided with a sealing cover, one side of the sealing cover is fixedly sleeved with three stroke rods, and the positions, close to one end of the shell, of the outer surfaces of the stroke rods are movably sleeved with the cutting device. A power machine is fixedly installed at the bottom of an inner cavity of the shell, the number of output shafts of the power machine is two, a compression roller device and an extrusion device are fixedly installed at one end of each output shaft, a straightening device is movably connected to the position, located on one side of the compression roller device, of the front face of the shell in a sleeving mode, and a switching device is fixedly installed at the top of the shell. A rubber ring is made of wear-resistant rubber, so that the rubber ring can remove rust which is not cleaned away when the steel bar passes through a straight pipe in the rotating process, the problem that the quality of a final product is poor due to the fact that a large amount of rust still exists after the steel bar is sheared is solved, and the quality of the final product produced by the device is improved.

Description

technical field [0001] The invention relates to the technical field of building materials machinery, in particular to a cutting device for a steel bar straightening machine. Background technique [0002] Rebar conditioning and cutting machine is a very versatile machine. In order to modulate and cut bent steel bars into suitable lengths in various construction sites, this machine will be used, even in some waste steel recycling. With this machine, the principle is that the bent steel bar can be straightened in the straight pipe by passing the steel bar into a straight pipe, and the straightened steel bar moves under the action of the pressure roller and is cut by the cutting device, and in order to Ensure that the cutter in the cutting device will not rub against the steel bar. The cutting device adopts a movable installation method and makes the cutter move synchronously with the steel bar at the moment of contact with the steel bar. After the steel bar is cut, the cutting ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the cutting device of the existing steel bar straightening machine proposed in the background technology, the present invention provides a kind of steel bar straightening machine The advanced cutting device has the advantage of ensuring that the cutting device can be completely reset without exceeding the stroke limit, and solves the problem of incomplete reset of the cutting device caused by too fast loading of steel bars, which causes huge friction between the cutter and the steel bars
