Detailed Description

For further explanation of the principles and construction of the present invention, reference will now be made in detail to the preferred embodiments of the present invention, which are illustrated in the accompanying drawings.

As shown in fig. 1-4, the double-head steel bar bending apparatus of this embodiment includes a rack 1, two sliding platforms 3, and two hoop bending heads 2, where the sliding platforms 3 are slidably disposed on the rack 1, and the hoop bending heads 2 are disposed on the corresponding sliding platforms 3.

The handpiece comprises a mounting seat 21, a rotating seat 22, a torsion shaft 23, a support column 24 and a driving mechanism 25, wherein the mounting seat 21 is arranged on the sliding platform 3, the rotating seat 22 is provided with a shaft hole (not marked), the rotating seat 22 is rotatably arranged on the mounting seat 21, the torsion shaft 23 is arranged on the rotating seat 22, the support column 24 is arranged on the mounting seat 21, and the support column 24 penetrates through the shaft hole; the free end of the torsion shaft 23 and the free end of the supporting column 24 both extend to the outside of the machine frame 1, a hoop bending space is formed between the free end of the torsion shaft 23 and the free end of the supporting column 24, and a driving mechanism 25 is arranged on the sliding platform 3 and is used for driving the rotating seat 22 to rotate.

Specifically, in the actual use, in the initial state, the rotation base 22 is driven to rotate by the drive mechanism 25, so that the torsion shaft 23 rotates to above the support column 24. Then, the operator puts the reinforcing bar between the two support posts 24 and under the torsion shaft 23, so that the driving mechanism 25 can drive the rotating base 22 to rotate. The rotating seat 22 in the rotating process drives the torsion shafts 23 to rotate, and the torsion shafts 23 on the two sides synchronously abut against the reinforcing steel bars so as to perform hoop bending operation on the two end parts of the reinforcing steel bars. Under the extrusion action of the torsion shaft 23, the reinforcing steel bar rotates downwards around the support column 24 at the corresponding end part; and because the free end of torsion bar 23 and the free end of support column 24 all extend to the outside of frame 1, like this, alright in order to ensure that the tip of reinforcing bar downwarping can not touch frame 1, and then avoid the reinforcing bar bending in-process to receive frame 1 to interfere and cause the circumstances of hoop bending failure to take place. Meanwhile, the opening frame 1 is avoided in the process of bending the reinforcing steel bar, so that the end part of the reinforcing steel bar can be bent for a long distance. In addition, in the hoop bending process, the reinforcing steel bars droop and are self-oriented by means of self gravity, and operators do not need to hold the reinforcing steel bars by hands or add a clamping mechanism, so that the labor intensity of workers can be reduced, and the processing efficiency is improved.

In other use scenes, the steel bar can be bent upwards by adjusting the initial position of the torsion shaft 23. For the steel bar which is bent, under the condition that the length of the part of the end part which needs to be bent and extends downwards is too long, the double-machine-head steel bar bending device of the embodiment can also be adopted, for the steel bar, the whole steel bar is of a bent structure, the part of the end part of the steel bar which extends downwards is longer, after the steel bar is placed on the supporting column 24, the end part of the steel bar sags and is positioned at the front side of the rack 1, and then when the torsion shaft 23 bends the steel bar, the end part of the steel bar rotates upwards and does not interfere with the rack 1. The specific use method of the double-head bending equipment is not limited herein.
