Abstract
The present invention discloses a roller for reinforcing bar threads, which comprises a set of rolling wheels, wherein thread teeth are evenly distributed on each roller. Each roller is arranged in a hollow cylinder through a roller shaft, and the revolving shaft centers of the rolling wheels are evenly distributed on the same circumference. Both ends of the roller shaft are sheathed with one-way thrust ball bearings, and the rolling wheels are combined with rolling wheels composed of cones and cylinders. The cones firstly conduct shaping and guiding to the workpieces to be rolled, and then the roll workpieces are rolled into straight threads. When the reinforcing bars are rolled, cutting is not required. The strength of the processed rolling pieces is improved, the efficiency is high, and the material consumption is little.
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 rolled thread device of steel thread end 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 rolled thread device that is used for rolling steel thread end, this rolled thread device 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 rolled thread device a weak point being arranged is in rolling, could be shaped after will cutting rolled piece, so above-mentioned rolled thread device 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 rolled thread device exists, a kind of efficient height is provided, consumptive material is few and processing after the rolled thread device of the high steel thread end of rolled piece intensity.
To achieve these goals, the present invention adopts following technical scheme: the same with existing rolled thread device, this rolled thread device, comprise that is rolled a wheel, whenever roll and be 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, be with single direction thrust ball bearing rolling the wheel shaft two ends, difference is: described roll the wheel be to roll wheel by the combination that cone and cylinder constitute, described screw thread teeth are distributed on the described cylinder at least.
Replace the single cone that original rolled thread device 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, the rolled thread device of steel thread end of the present invention 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 form equidistant ring screw thread teeth, the surface also can form straight trough, skewed slot, also can arrange the cone that forms various pits on the surface, even can be the cone that the surface forms 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 angular thread teeth, trapezoidal thread teeth on the cylinder 22, 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 single direction thrust ball bearing 4 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, rolled thread device of the present invention is placed on the special-purpose milling train, rolled piece is penetrated in the central through hole of rolled thread device, starting milling train can be rolling to it, behind rolling finishing, to respectively roll the wheel rotation eccentric axis and forward rotate, and make and roll wheel and throw off rolled piece, take out the rolled piece after rolling.
