Two adjusting screw(rod)s 52 are the distances for regulating between the initial position of foldable component and hold-down mechanism (compact heap 82), namely the length of run of shaping front reinforcing bar is regulated, thus the waveform spacing of reinforcing bar to final molding (distance on the waveform reinforcing bar namely formed between adjacent peaks or trough) controls.Therefore, the adjustment final body of two adjusting screw(rod)s 52 is now to the adjustment of waveform spacing.
Preferably adopt motor 51 to drive driving gear 61 to drive two driven gears 62 to rotate herein and drive adjusting screw(rod) 52, and then reach the object regulating waveform spacing, two driven gears 62 are connected with a joggle with driving gear 61 respectively, stable drive; Adopt motor 51 to control to adjust, can ensure that the regulated quantity of two adjusting screw(rod)s 52 is consistent, avoid producing error because regulating manually, guaranteeing stable regulation.
In addition, between motor 51 and driving gear 61, a reductor can also be installed, make the transmission between motor 51 and driving gear 61 more steady, ensure the stability regulated further.
As shown in Figure 1 to Figure 3, preferably, foldable component comprises the first slide 21 be flexibly connected with frame, oil cylinder 10, two adjusting screw(rod) 52 is connected with the first slide 21 respectively, wheel shaft is equipped with near one end level of oil cylinder 10 at the first slide 21, wheel shaft two ends pass the first slide 21 respectively and are arranged with gear 43, and frame is installed with two fixed racks 41 be connected with a joggle with two gears 43 respectively.
Preferably, accessory part comprises the second slide 31, second slide 31 be flexibly connected with frame and to be positioned at above the first slide 21 and to be provided with two carry-over bars 42 be connected with a joggle with two gears 43 respectively in the second slide 31 bilateral symmetry.
Particularly, oil cylinder 10, two adjusting screw(rod) 52 is connected with the first slide 21 respectively, during bending work, oil cylinder 10 drives the first slide 21 to move towards hold-down mechanism, under the effect of cooperatively interacting of two fixed rack 41, two gears 43 and two carry-over bars 42, second slide 31 moves towards hold-down mechanism along with the first slide 21, and namely oil cylinder 10 drives the related accessory part of foldable component to move towards hold-down mechanism.
When above-mentioned first slide 21 moves, because fixed rack 41 does not move, therefore two gears 43 roll along with the movement of the first slide 21 on the fixed rack 41 of correspondence.Now, because two carry-over bars 42 are connected with a joggle with two gears 43 respectively, related second slide 31 of two carry-over bars 42 moves along with two gears 43, close towards hold-down mechanism.
It is worth mentioning that, because two carry-over bars 42 are movements on the basis of two gear 43 movements, therefore, when the first slide 21 moves the distance of X towards hold-down mechanism, second slide 31 moves the distance of 2X towards hold-down mechanism, be conducive to that forming shape is stablized, symmetrical configuration, waveform reinforcing bar attractive in appearance.
In the present embodiment, first slide 21 bilateral symmetry is provided with multiple first pulley, in frame, symmetry offers two first chutes that arrange corresponding to the first pulley, and the first pulley of every side can roll in the first chute of correspondence, drives the first slide 21 slippage.Therefore, operationally the first slide 21 can along frame slippage, gradually near hold-down mechanism.
Similarly, the second slide 31 is symmetrically arranged with multiple second pulley, in frame, also symmetry offers two second chutes that arrange corresponding to the second pulley, and the second pulley of every side can roll in the second chute of correspondence.
Further preferably, vertically be provided with fore-set 22 at the first slide 21 away from one end of oil cylinder 10, fore-set 22 is installed with top 23, and on top 23, symmetry offers two bending grooves 231, in each bending groove 231, all level is equipped with apical axis 71, and fore-set 22 can move related top 23 straight up.
Further preferably, second slide 31 is vertically installed with symmetrically arranged two guide plates 32, between two guide plates 32, be provided with compressed oil cylinder 34 and be fixed with auxiliary block 33 on compressed oil cylinder 34, auxiliary block 33 offers two auxiliary tanks 331 that arrange corresponding to two bending grooves 231, and between two guide plates 32, level is equipped with the last item 72 be positioned at above auxiliary block 33.
Reinforcing bar charging is successively by accessory part, foldable component, the end that reinforcing bar is positioned at hold-down mechanism place is fixed by compact heap 82, during work, oil cylinder 10 drives related second slide 31 of the first slide 21 to move towards hold-down mechanism, simultaneously, top 23 to be moved straight up and to carry out bending to reinforcing bar under fore-set 22 drives, in this process, accessory part carries out spacing, fixation to reinforcing bar together with hold-down mechanism, ensure that reinforcing bar keeps stable in the whole bending course of work, do not offset.
In the present embodiment, arranging of two bending groove 231, two auxiliary tanks 331 can carry out bending work to two reinforcing bars simultaneously, greatly can increase work efficiency, also be convenient to the carrying out of follow-up work.
