Abstract
A rolling roller for screw-thread reinforcing bar includes a group of rolling wheels. Each rolling wheel has spiral teeth uniformly distributed on it. All the rolling wheels are contained in same hollow cylinder by axles and their rotational axises are uniformly distributed on same circumference. The monodirectional thrust ball bearings are installed to both ends of rolling wheel axle. Said rolling wheel is composed of conic body and cylindrical body. The conic body can shape and guide the workpiece which is then rolled to have straight screw thread. Its advantages are no need of cutting, high efficiency, less loss of material and high strength of rolled workpiece.
Description
What the present invention relates to be specially adapted for rolling mill for metal carries out the additional metal process equipment, is meant a kind of roller for screw thread steel particularly.
For the connection between the reinforcing bar, usually adopted the method for attachment of the current international practice, Here it is is rolled into tapered thread with the termination of the reinforcing bar that will connect, the female adapter sleeve of apparatus connects two reinforcing bars then, as Chinese patent application numbers 96229421.7 is exactly to disclose a kind of roll that is used for rolling screw thread steel, this roll rolls wheel by one group (2 to 3) and constitutes, each rolls and is evenly equipped with teeth on the wheel, respectively rolling wheel is evenly distributed on the same circumference, on the axle that rolls the wheel two ends, be with the bearing of unilateral thrust, respectively rolling wheel, to also have a notable attribute be exactly that each rolls wheel and is coniform, so, when utilizing the rolling reinforcing bar of this roll a weak point being arranged is in rolling, could be shaped after will cutting rolled piece, so above-mentioned roll exists efficient low when reality is used, the shortcoming of consumptive material also exists the shortcoming that the intensity of the reinforcing bar after being rolled weakens simultaneously to some extent.
The objective of the invention is to overcome the shortcoming that above-mentioned roll exists, a kind of efficient height is provided, consumptive material is few and processing after the high roller for screw thread steel of rolled piece intensity.
To achieve these goals, the present invention adopts following technical scheme: the same with existing roller for screw thread, this roller for screw thread comprise that is mainly rolled a wheel, each rolls and is evenly equipped with the screw thread teeth on the wheel, respectively rolling wheel places in the hollow cylinder by rolling wheel shaft, and the revolution axle center of respectively rolling wheel all is evenly distributed on the same circumference, is with the ball bearing of unilateral thrust at the two ends of rolling wheel shaft, and difference is: described roll the wheel be to roll wheel by the combination that cone and cylinder constitute.
Replace the single cone that original roll adopts and roll wheel because the present invention has adopted the combination that is made of cone and cylinder to roll wheel, the conical section that wheel is rolled in combination carries out shaping, guiding earlier to required rolling workpiece, after be rolled into straight thread, so when reinforcing bar is rolled, rolled piece intensity after need not cutting, processing improves greatly, and efficient height, consumptive material are few.
Below in conjunction with drawings and Examples, the present invention is described in further detail:
Fig. 1 is the axial sectional structure schematic diagram of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
See also Fig. 1, shown in Figure 2, this roller for screw thread steel mainly comprise one group roll the wheel 2, the quantity of rolling wheel 2 can adopt two or three, can certainly adopt four, in Fig. 1 and Fig. 2, illustrate three and rolled wheel, each rolls wheel 2 is to constitute combination by cone 21 and cylinder 22 to roll wheel, the surface of cone 21 parts can be equidistant ring screw thread teeth, the surface also can be furnished with straight trough or skewed slot, also can be for arrange the cone of various pits on the surface, even can be the cone that the surface is smooth plane, cone 21 parts of rolling wheel 2 play 7 guiding of rolled piece reinforcing bar, shaping, the effect of extruding, and shaping, extruding be again to reinforcing bar 7 can rolling straight thread key point.Roll on wheel 2 cylinder 22 parts and be furnished with the ring screw teeth, certainly also can be furnished with the angular thread teeth on the cylinder 22, the trapezoidal thread teeth, respectively rolling wheel 2 places in the hollow cylinder 1 by rolling wheel shaft 3, and the revolution axle center of respectively rolling wheel 2 all is evenly distributed on the same circumference, if there are three to roll wheel, three angles each other 120 that roll between the wheel shaft 3 then, be with the ball bearing 4 of unilateral thrust respectively at the two ends of respectively rolling wheel shaft 3, roll wheel 2 between ball bearing 4, also having packing ring 5 to be placed in the outside of each bearing 4 rolls on the wheel shaft 3, can regulate adjacent wheel 2 axial locations that roll like this, be the N root if roll wheel 2 numbers, the pitch of screw thread teeth is T, and then adjacent axial location difference of rolling wheel is T/N.As previously mentioned, all roll wheel 2, roll in the cylinder 1 that wheel shaft 3 all is positioned over an end opening, the other end of cylinder 1 covers with one, and central through hole that rolled piece 7 (reinforcing bar) can penetrate and the through hole that rolls wheel shaft 3 are all left in the two ends of cylinder 1.
Its course of work is the same with common milling train, and this roll is placed on the special-purpose milling train, and rolled piece is penetrated in the central through hole of roll, starting milling train can be rolling to it, behind rolling finishing, will respectively roll the wheel rotation eccentric axis and forward rotate, make and roll wheel and throw off rolled piece, take out the rolled piece after rolling.
Claims (4)
