Concrete-bar straightening cutting machine

Abstract

The invention discloses a steel-bar drawing-in and cutting machine. This device comprises a device for holding the disc-form steel bar, to-and-fro automatic clamping and stretching mechanism, feeding, cutting and locking devices. The to-and-fro mechanism comprises a base which is fixed on the ground and is fitted with a guiding device having and is also fitted with guide slot which has a moving frame driven by power device. The frame comprises an upper toothed plate fitted on upper part of the frame and a rocker which has a crank lever whose middle part in hinged oh the frame and at the two ends of the crank lever are respective movably fitted with a lower toothed plate matched with the upper toothed plate and a guide wheel moving along the guide device. Advantages: it needs no sectional cutting so as to fully utilize raw material and it has better drawing-in effect.

Description

technical field [0001] The invention relates to a steel bar straightening and cutting machine. Background technique [0002] At present, in the construction of engineering buildings, it is usually necessary to use steel bars as the skeleton of cement components, so the disc-shaped steel bars must be straightened. The existing method of straightening steel bars is to first pull the disc-shaped steel bars to the Cut after a certain distance; then one end of the steel bar is spliced ​​to the fixing device, and the other end is spliced ​​to the fixing ring of the stretching device. After the steel bar is straightened, the steel bar is cut into sections with a shear or cutter. The workers of this processing method have high labor intensity and low production efficiency, and because the twisted joints at both ends of the steel bar need to be cut before use, the waste of steel bar raw materials is caused, which is difficult to meet the requirements of people's production efficiency...

The workers of this processing method have high labor intensity and low production efficiency, and because the twisted joints at both ends of the steel bar need to be cut before use, resulting in waste of steel bar raw materials, it is difficult to meet the current people's requirements for high production efficiency and material conservation
