Abstract
The utility model relates to a cold rolling torsion machine for rod bundles, which belongs to cold rolling equipment for processing rod bundles. The utility model comprises a straightening device (4), a flattening device, a torsion device (7) and a cutting device (8), wherein, the straightening device is a four-wheel straightening mechanism, and at least one shaft in the straightening wheels is arranged in a groove (16) arranged on a box body (11) of the straightening mechanism and can do up and down sliding adjustment. The mechanical parameter of the rod bundles can be changed through changing the relative positions among the straightening wheels, so the mechanical parameters of the finished goods of cold rolling torsion rod bundles are easy to be uniform. In addition, the operation in rod bundles filling is more convenient.
Description
The utility model relates to a kind of process equipment of cold rolling process equipment, particularly cold-rolled torsion steel bar for building of reinforcing bar.
Common disk reinforcing bar is through cold rolling, cold twisting processing, by draw down, stretch, be twisted into profile and be continuous helical curved surface shape, is used for architectural casting reinforced concrete, can save great deal of steel.Chinese patent 90226162.6 has been introduced a kind of equipment of processing cold-rolled torsion steel bar, at present wide popularization and application at home.
The purpose of this utility model is this steel bar cold rolling to be turned round machine do further to improve, and makes the easier adjusting of mechanics parameter of processed cold-rolled torsion steel bar.
This disk steel cold pressing and wreathing machine comprises machine straightening device, draw down device, torsion device and shearing device.Machine straightening device is a four-wheel straightening mechanism, and the draw down device comprises two rolls, motor, gear-box and branch square case, and torsion device comprises torq, guide cup, an a pair of running roller and the torsional angle dish of reversing.Have at least one axle to be contained in the groove on the straightening mechanism casing in the straightening wheel of described four-wheel straightening mechanism, and can slide up and down adjusting along this groove.
This disk steel bar cold rolling is turned round machine, because the position of the straightening of its four-wheel straightening mechanism wheel can be regulated, relative position between the straightening wheel can change, thereby can change processed reinforcing bar by the time degree of crook and draw the power of dialling, so changed the cold-drawing deformation and the mechanics parameter of reinforcing bar, thereby can do preconditioning to reinforcing bar, make the mechanics parameter of finished product cold-rolled torsion steel bar be easy to uniformity, and be controlled at optimum state.In addition, in filling during reinforcing bar, can be with movable straightening rotation pine, filling is just got up easily, and thicker reinforcing bar also can load easily as the reinforcing bar of φ 14, is particularly suitable for the cold-rolled torsion steel bar of rolling large-size.
Accompanying drawing 1 is turned round the overall structure figure of machine for this disk steel bar cold rolling;
Accompanying drawing 2 is the structure chart of four-wheel straightening mechanism;
Accompanying drawing 3 is the movable straightening wheel of straightening mechanism and the catenation principle figure of casing;
Accompanying drawing 4 is the structure chart of straightening mechanism feed side face;
Accompanying drawing 5 is the relative position figure of roll and torq;
Accompanying drawing 6 is a kind of sectional view of cold-rolled torsion steel bar.
As shown in Figure 1, (5) are machine straightening device, and it is a four-wheel straightening mechanism.The draw down device comprises two rolls (6), motor (1), gear-box (2) and divides square case (3).(7) be torsion device, (5) are processed reinforcing bar, and (8) are shearing device, and (9) are universal connecting shaft.
The structure of four-wheel straightening mechanism as shown in Figure 2, (11) be the casing of four-wheel straightening mechanism, charging guide pin bushing (15) is housed above, discharging guide pin bushing (12) and four straightening wheels (14), (18), the straightening wheel relies on their axle to be fixed on the casing, wherein two accent wheels (14) are fixed, and two straightening wheels (18) are movable in addition.The annexation of movable straightening wheel (18) and casing as shown in Figure 3, the axle (17) of movable straightening wheel is contained in the groove (16) on the casing (11), can slide up and down along this groove, regulate finish after available nut (19) fix.As shown in Figure 2, the upper-lower position of regulating movable straightening wheel can change the deformation extent of reinforcing bar (13).Filling upwards moves movable straightening wheel during reinforcing bar, and reinforcing bar can not add agley straight-through and mistake between four straightening wheels.After loading onto reinforcing bar, more movable straightening is taken turns (18) to pressing down, to reach the certain deformation amount.
As shown in Figure 2, for make filling during reinforcing bar movable straightening wheel press down more laborsavingly, can an adjusting screw(rod) (10) be set in the top of movable straightening wheel (18), after reinforcing bar penetrates between the straightening wheel, rotate adjusting screw(rod), movable straightening wheel (18) is pressed down put in place, fasten again.
As shown in Figure 4, needs for the diverse location that adapts to movable straightening wheel, on the side of the feed side of the casing of four-wheel straightening mechanism a chute (21) can also be arranged, several wide hole portions (20) are arranged on this chute, charging guide pin bushing (15) is loaded in one of them wide hole portion.When the filling reinforcing bar, earlier the charging guide pin bushing is gone up from the side and taken out, be enclosed within on the reinforcing bar, after reinforcing bar inserts straightener, can in the chute (21) of casing side, move up and down, behind the good movable straightening wheel to be adjusted, on side chute (21), choose the wide hole portion (20) of a correct position again, insert charging guide pin bushing (15), can process reinforcing bar.
As shown in Figure 5, the torq (26) of torsion device (7) is pressed on the side plate (27) of draw down device by torsional angle dish (25), and guide cup (23) and a pair of running roller (24) that reverses are housed on the torq, and (22) are roll among the figure.For the mechanical property to cold-rolled torsion steel bar better is optimized, reversing the spacing of running roller (24) can regulate also not exclusively equal with the spacing of roll (22), two ratios that reverse the spacing of the spacing of running roller and roll can be chosen between 1-1.4:1, (for example: change the diameter that reverses running roller reverses running roller with adjusting spacing) is when this ratio is big, through reversing the squeezing action of reversing of running roller, the cross section of cold-rolled torsion steel bar can become approximate rhombus as shown in Figure 6, increased the thickness of cold-rolled torsion steel bar, its tensile strength, mechanical property such as percentage elongation and cross section are that the cold-rolled torsion steel bar of rectangle is identical, thereby change the performance that this gap ratio also can be adjusted the cold rolling and cold twisting process of cold-rolled torsion steel bar.
This disk steel bar cold rolling is turned round machine, owing to its straightening mechanism and torsion device working process parameter can both be regulated, thereby more flexible to the parameter adjusting of rolling reinforcing bar, the cold-rolled torsion steel bar finished product of the performance parameter that more is easy to get unanimity.
