Abstract

The utility model relates to a straightening machine for steel bars, which is composed of a transmission system, a straightening mechanism, a machine base, etc. The straightening mechanism and a conveying mechanism are combined to form a whole, and an electrical machine drives a regulating frame to rotate by a drive wheel and a driven wheel; two bottom plates are arranged in the regulating frame, three straightening wheels which are ranged in staggered mode are arranged on each bottom plate, and an included angle of 45 DEG or 135 DEG is formed between the longitudinal axial line of each straightening wheel and the symmetric central line of the regulating frame. The utility model has the advantages of simple structure, low labor intensity and low energy consumption; the utility model can be widely used in construction sites.

Description

Bar straightener

The utility model relates to a bar straightener.

The bar straightener of Shi Yonging is rectified reinforcing bar and passed straight tube after guiding in the past, and the straightening piece of five rotations is arranged in it, reinforcing bar enters between the upper and lower traction roller after the straightening of straightening piece again, makes constant speed by the traction roller and rotates, drive material by friction and advance, finish whole straightening work.This machine separates with conveying mechanism two owing to straightening mechanism, so need before each material loading just entering straightener after the artificial straightening of material front end 1000mm length, like this, operation is extremely inconvenient, and complex structure, the body heaviness, the cost height, energy consumption is big, and power is more than the 4kw, voltage needs 380V, limited by the place.

The purpose of this utility model provides a kind of work efficiency height, and cost is low, is convenient to maintenance, and easy operating, straightening mechanism and conveying mechanism are the straightener of one.

For achieving the above object, bar straightener of the present utility model is mainly by transmission system, the straightening system, compositions such as support, flat key and drive pulley are arranged on the output shaft of motor, link to each other with driven pulley by V belt, flat key on driven pulley and the accent frame, nut connects, its outside is provided with protective cover, transfer frame to be shelved on the frame of bearing bracket stand together with radial ball bearing, transfer the top and the bottom of frame to be respectively installed with three equidistant adjustment screw rods, adjusting screw rod links to each other with strong wheel base plate, rectify on the wheel base plate strong wheel shaft is housed, rectify a strong wheel respectively is housed on the wheel shaft, top is rectified wheel axis and is transferred the symmetrical center line angle at 45 of frame, and the angle that wheel axis and symmetrical center line are rectified in the bottom is 135 °; Transfer frame to have charging hole, transfer the frame other end that discharging is arranged by pulley end.Straightener is rectified and to be taken turns longitudinally that outer surface is a recessed garden cambered surface, transfer 33 of rectifying wheel and its underpart on frame top to rectify staggered corresponding layout of wheel, and the strong orthogonal interlaced arrangement of wheel axis of wheel axis and bottom is rectified on top.

Because adopted technique scheme to make the bar straightening quality meet national standard, and energy consumption is low, its power only is 1.1kw, voltage be 220V or 380V all can, the straightening material specification can be Φ 4-Φ 10 (mm), and is simple in structure, move conveniently, be convenient on the construction site, be extensive use of.

Fig. 1 is the structural representation of bar straightener;

Fig. 2 is for rectifying the structural representation of wheel base plate;

Fig. 3 rectifys the A of wheel base plate to oblique view.

As shown in Figure 1, this machine has motor 1, motor is fixed on the motor cabinet by screw 5, driving wheel 4, flat key 3, protective cover 6, driven pulley 13 are arranged in the driving wheel, flat key 10 is arranged in the driven pulley, driving wheel links to each other by V belt 2 with driven pulley, and base plate is fixed on base plate on the accent frame 11 by screw rod 16 and nut 15, and regulate by nut, the frame 11 of accent is arranged on the support 14, transfer the axle at frame two ends to be fixed on the support, bearing 7 is arranged in the bearing block by bearing block, driven pulley cooperates with the left end shaft of transferring frame, and is fixing with nut 12.Transfer the frame both sides to be equipped with 3 respectively and rectify wheel 22, rectify wheel 22 and be contained on the base plate 17 and can rotate, rectify on the wheel shaft 20 packing ring 18, split pin 19, radial ball bearing 21 are housed around strong wheel shaft 20.During work, being rectified reinforcing bar enters the accent frame 11 from charging hole 24, wherein rectify wheel and rectified radial component generation torsion and the bending force that material contact the frictional force that produces for 6, make moment reinforcement be able to straightening, another axial thrust load of frictional force makes by strong reinforcing bar from discharging opening 23 outputs, the gap length of rectifying between wheel is a diameter of being transferred reinforcing bar, after fixing first base plate, the adjustment requirement of second base plate and method are to adjust screw rod by it to regulate, make three outer gardens of rectifying the recessed garden cambered surface contact standard lining bar of wheel on this plate, but should keep the lining bar must not be crooked, rectify the wheel exposure levels and answer basically identical for three up and down.

After all fixedly finishing, should check contact degree and position and the nut fastening situation of standard lining bar between accent frame two holes between each strong wheel once more, curving 90 ° at discharge port end outside lining bar 100mm then grasps, slow change sample frame (forbid start) withdraw from lining bar install transfer the frame protective cover after, can trial run work.

During the straightening long material, at first starter motor after waiting to reach rated speed, is advanced charging hole rectifying the material front end, when material after the straightening surpasses discharging nose end 150～200mm, must draw with hand.
