Electric automatic steel bar cutting machine

Abstract

The invention relates to the technical field of steel bar cutting equipment, and discloses an electric automatic steel bar cutting machine which comprises a cutting knife, a fixing part, a first movable cutting mechanism, a microprocessor and a power source. The fixing part is used for supporting and clamping a steel bar to enable the steel bar to be higher than the ground, and the first movable cutting mechanism comprises a connecting body. A clamping part is connected to the upper end of the connecting body and can clamp or loosen the steel bar, a walking part is connected to the lower end of the connecting body so that the connecting body and the clamping part can walk in the axial direction of the steel bar, a bearing seat is fixedly connected to the side, away from the fixing part, of the connecting body, and an electric telescopic rod stretching out and drawing back in the vertical direction is fixed to the upper end of the bearing seat. The cutting knife is fixed to the telescopic end of the electric telescopic rod, a distance sensor is arranged on the side face, opposite to the fixing part, of the connecting body, and the microprocessor is in signal connection with the clamping part, the walking part, the distance sensor and the electric telescopic rod. The problem that when a long and thin steel bar is cut, the cutting face is an inclined face due to bending of the steel bar is solved.

Description

technical field [0001] The invention relates to the technical field of steel bar cutting equipment, in particular to an electric automatic steel bar cutting machine. Background technique [0002] With the popularization of electrical automation technology, more and more traditional equipment is combined with electrification technology, so that the traditional equipment can complete the automatic operation, and then the electrical automation steel bar cutting machine appears. [0003] At present, the common electric automatic steel bar cutting machine is mainly composed of motor, transmission system, deceleration mechanism, crankshaft mechanism, traction mechanism, body and cutting knife, etc. The feeding of the steel bar is driven by the traction mechanism, so that the cutting knife at the fixed feeding position It cuts automatically. [0004] Since the traction mechanism is set on the body, it can only be fed by pulling the steel bars close to the body. In this way, for so...

AI Technical Summary

Problems solved by technology

[0004] Since the traction mechanism is set on the body, it can only be fed by pulling the steel bars close to the body. In this way, for some slender steel bars, the end of the steel bar away from the body will inevitably sag due to the gravity of the steel bar itself, and the steel bars as a whole will not be in place. On the same horizontal line, so that the steel bar produces a large vertical component force on the traction mechanism, so when the cutting knife cuts it, the cutting surface becomes an inclined surface because the steel bar is not straight enough, which affects the cutting effect
