Mouse cage type steel rebar prestress straightening machine

Abstract

The invention discloses a mouse cage type steel rebar prestress straightening machine. The mouse cage type steel rebar prestress straightening machine comprises a transmission frame, a transmission sleeve barrel, transmission rolling shafts, a first motor, a mounting frame, a sensor, a second motor, pulling rollers, rotors, electronic flying shears, a controller and a bellmouth. The transmission rolling shafts are mounted at the transmission frame by rotary shafts; the transmission sleeve barrel is welded in the middle of the transmission frame and communicates with the bellmouth; the first motor and the second motor are orderly mounted at the mounting frame and the sensor is mounted between the first motor and the second motor; the pulling rollers are mounted at the rotors which are arranged in the first motor and the second motor; the electronic flying shears are mounted at the tail end of the second motor; the controller is electrically connected with the first motor, the second motor and the electronic flying shears. The straightening effect can be realized by using mouse cage type speed-adjustable variable-frequency motors and placing straightening drums into the motor rotors,then enabling a straightened steel rebar to pass through the straightening drums under the forcing action of the asymmetrical pulling rollers, and using the eccentricity of straightening moulds to make the steel rebar plastically deform continuously and repeatedly; meanwhile, the prestress is imparted to the straightened steel rebar under the straightening working tension at different speed of the two frequency modulation motors.

Description

technical field [0001] The invention relates to the technical field of municipal building construction machinery, in particular to an intelligent squirrel-cage steel bar prestress straightening machine device. Background technique [0002] The traditional straightening machine, its body structure is composed of: motor, V-belt, straightening mechanism, control mechanism, clutch, braking device, gearbox and so on. It is driven by a motor through a V-belt to drive the straightening cylinder to rotate at high speed. There are five adjustable straightening dies in the straightening cylinder. The steel bar to be straightened passes through the straightening cylinder under the force of the traction roller. The eccentricity of the straightening die makes the steel bar obtain repeated plastic deformation for many times, but the problem is that only The reinforcement is simply straightened and does not prestress the reinforcement. Contents of the invention [0003] The purpose of ...

Problems solved by technology

There are five adjustable straightening dies in the straightening cylinder. The steel bar to be straightened passes through the straightening cylinder under the force of the traction roller. The eccentricity of the straightening die makes the steel bar obtain repeated plastic deformation for many times, but the problem is that only The bars are simply straightened without prestressing the bars
