[0040] One end of the power shaft 32 is also fixed with a hand wheel 5 arranged concentrically.
[0041] Working principle:
[0042] One end of the steel bar is threaded from right to left between the first straightening wheel assembly and the second straightening wheel assembly, then threaded between the two follow-up wheels 336 in each follow-up wheel assembly, then extended from below the pressing beam 338 to above the rotating disc 313 and located between the two bending wheels 332, and then extended into between the two limiting blocks 331.
[0043] Subsequently, the motor 31 in the power mechanism is started to rotate the rotating shaft, and then the power shaft 32 is driven to rotate by the first pulley 35, the second pulley 36 and the first belt 37, so that the first transmission shaft 34 is driven to rotate by the second gear 33 and the third gear 38, and then the rack 310 is driven to translate leftward by the first connecting rod 39, so that the rotating shaft 312 is driven to rotate by the first gear 311 in the bending mechanism, and then the rotating disc 313 in the bending module is driven to rotate, so that the steel bar is gradually bent by the two bending wheels 332.
[0044] At the same time, the rotation of the first transmission shaft 34 also drives the swing sleeve 333 in the fourth transmission assembly to rotate, and then the first swing rod 315 driven by the follow-up ring 314 moves leftward or rightward, so that the traction block 317 is swung leftward or rightward by the second swing rod 316, and then the follow-up block 335 is swung forward or backward by the follow-up shaft 339 to drive the pressing beam 338 and each follow-up wheel assembly to swing forward or backward, so as to adapt to the angle of the bent steel bar.
[0045] Meanwhile, the rotation of the first transmission shaft 34 also drives the third belt wheel 318 in the second transmission assembly to rotate, and then drives the second transmission shaft 319 and the transmission disc 322 to rotate through the fourth belt wheel 320 and the second belt 321, so as to drive the slider 324 in the cutting-off mechanism to move rightward through the second connecting rod 323, and then drive the rocker arm 327 and the pulley 328 in the third transmission assembly to move rightward, so that the pulley 328 rolls from the guide inclined surface 3292 to the right-angle notch slot 3291, and then forces the end of the rocker arm 327, where the pulley 328 is located, to swing downward, so as to force the pressing rod 325 to move downward, and then drive the cutter plate 326 to move downward and cut off the bent steel bar through the cutter plate 326.
[0046] Since one end of the first connecting rod 39 is eccentrically connected to one side end surface of the third gear 38, the rack 310 moves reversely to reset after moving a certain distance, and since one end of the second connecting rod 323 is eccentrically connected to one side end surface of the transmission disc 322, the slider 324 also moves reversely to reset after moving a certain distance, and since the swing sleeve 333 is eccentrically sleeved and fixed on the first transmission shaft 34, the pressing beam 338 and each follower wheel combination swing reversely to reset after swinging forward or backward, so that the processing mode of cyclic reciprocation is realized.
[0047] The utility model has the functions of cutting off and bending simultaneously, the steel bar connecting piece can complete the fixed-length cutting off and the fixed-type bending in sequence and automatically in one equipment, and then the process of feeding and discharging once is reduced, so that the operation steps are simplified to save time and labor and improve the processing efficiency; in addition, the power sources of cutting off and bending are all from the motor 31, and other electric or pneumatic equipment is not needed, so that the structure is simple and the manufacturing cost is low.
[0048] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
