Description
Technical Field
The invention belongs to the technical field of auxiliary equipment for processing reinforcing steel bars, and particularly relates to an automatic protection system of a wire rod reinforcing steel bar forming machine.
Background
When the wire rod reinforcing steel bar is used in the building engineering, the wire rod reinforcing steel bar needs to be straightened and cut off and then is molded according to requirements. The straightening mode that present novel steel bar forming machine adopted is the mode of rotatory alignment frame in order to prevent that the reinforcing bar from not damaging the reinforcing bar at the in-process of alignment. Under this kind of alignment mode, eight alignment wheels divide into two sets ofly and rotate at a high speed around the reinforcing bar that is aligned, and the reinforcing bar can receive the effect of force in alignment frame direction of rotation for the reinforcing bar has rotatory torsion.
This kind of novel reinforcement forming machine mainly takes shape end muscle or gluten, the angle of colluding at both ends is 135 or 90 promptly, its theory of operation is for straightening the wire rod reinforcing bar earlier, then go forward, it stops to walk to the correct position of sinuous winding, the sinuous winding action is according to the first of the angle bend that has set for, continue to walk forward and has stopped to the length of setting for, the cutter action cuts off the reinforcing bar then the sinuous winding action is according to the second of the angle bend first reinforcing bar that has set for colluding, it is good to collude for the bend simultaneously also the first of next reinforcing bar, just can be the wire rod reinforcing bar as required shaping through such a process. The in-process that the aforementioned reinforcing bar can receive a rotatory external force effect at the alignment, makes the reinforcing bar can rotate, and this novel steel bar forming machine colludes on same plane for two of guaranteeing the shaping back reinforcing bar, so is provided with a discharging device, and this discharging device is a thin groove width 5cm, high 130cm, and the lower extreme opening is sealed to the upper end. When the automatic steel bar bending machine works, after the steel bar is bent at a set angle to form the first hook, the movable plate at the lower end of the discharging device is sealed. The reinforcing bar advances along discharging device, has reached to set for length to cut off curved second and colludes, and the shaping reinforcing bar falls down is opened to the fly leaf, has guaranteed like this that the reinforcing bar can not the indiscriminate commentaries on classics just also guarantee that fashioned end muscle or two of gluten collude on same plane.
According to this principle reinforcing bar can receive the rotatory exogenic action that alignment frame gave at discharging device's the in-process that advances, if the staff adjusts improper to alignment frame in the application of reality, perhaps feed arrangement is not smooth, can lead to the rotatory exogenic action grow that the reinforcing bar received, end muscle or gluten card after the shaping are in discharging device. The machine continues to work, and next end muscle or gluten enter into discharging device again, and this discharging device is width just for little originally, and end muscle or gluten can not fall again like this, and so vicious circle will lead to the steel bar forming machine to break down or damage the machine, can seriously make the staff be injured.
