In severe cases, it will cause axial torsion of the steel bars, thereby affecting the straightness of the steel bar straightening and the qualified rate of the stirrup finished products. Utility Model Content
[0003] The main purpose of the utility model is to provide a steel bar torsion correction mechanism, a steel bar straightening machine and a steel bar processing production line, aiming to solve the problem of poor straightness of steel bars processed by existing roller-type steel bar straightening machines.
[0004] To achieve the above-mentioned purpose, the steel bar torsion correction mechanism proposed in the utility model comprises two torsion wheels, the two torsion wheels are aligned in a first radial direction and are rotatably arranged along the axis at which the two torsion wheels are axially located;
[0005] In the axial direction, the twisting wheel has a twisting section and a passing section, the two passing sections are arranged at intervals to form a passing gap, the passing gap is used to allow at least one steel bar to pass through, the two twisting sections are arranged in opposite positions, and a twisting ring groove is formed on each of the twisting sections, a twisting channel is defined between the two twisting ring grooves, and the twisting channel is used to allow a single steel bar to pass through after correction;
[0006] Wherein, the position of at least one of the twisting wheels in the axial direction is adjustable.
[0007] In the technical solution provided by the utility model, since the two torsion wheels in the steel bar torsion correction mechanism respectively have the torsion section and the passing section, and the torsion channel formed by the torsion ring groove on the torsion section can allow the steel bar to pass through, when the steel bar needs to be torsion corrected, by adjusting the axial position of one of the torsion wheels, the steel bar can be squeezed in the axial direction by the relative side walls of the two torsion ring grooves during the process of passing through the torsion channel, thereby applying a corrective torque along the circumferential direction of the steel bar, so that the torsional stress inside the steel bar can be released, thereby achieving the purpose of torsion correction of the steel bar and improving the straightness quality of the steel bar processed by the steel bar straightening machine; not only that, due to the setting of the passing section, the passing gap formed therein can straighten and pass other steel bars, which can improve the processing efficiency of the steel bar straightening machine. At the same time, when the torsion wheel is adjusted in the axial direction, the steel bar in the passing gap is subjected to a smaller axial force, which does not affect the passage of the steel bar therein.
[0008] In some embodiments, the torsion annular groove has two opposite annular groove side walls, and the distance between the two annular groove side walls gradually increases in a first radial direction away from the torsion wheel.
[0009] According to the above technical solution, in order to adapt to the axial misalignment of the two torsion wheels, the spacing between the two annular groove side walls is set to gradually increase, so that the extrusion force of the annular groove side walls on the steel bars is offset toward the tangential direction of the steel bars, thereby providing the largest possible circumferential correction torque and improving the torsional correction efficiency of the steel bars.
[0010] In some embodiments, the two torsion wheels include a movable torsion wheel and a fixed torsion wheel, and a positioning ring groove is formed on the passing section of the fixed torsion wheel, and the positioning ring groove is used to accommodate the steel bar.
[0011] According to the above technical solution, due to the setting of the positioning ring groove, the steel bar can always remain in the positioning ring groove when passing through the national gap, further reducing the impact of the movable torsion wheel on the steel bar in the gap when adjusting the axial direction.
[0012] In some embodiments, an annular protrusion is formed at the torsion section of the movable torsion wheel;
[0013] One of the torsion ring grooves is formed on the annular protrusion.
[0014] According to the above technical solution, by setting the annular protrusion, the torsion ring groove on the movable torsion wheel can actively approach the torsion ring groove on the fixed torsion wheel, which means that in the process of producing the steel bar torsion correction mechanism, it is only necessary to turn the corresponding step on the passing section of the movable torsion wheel, and the fixed torsion wheel can be set as a round shaft to meet the conditions for the formation of the torsion ring groove and the passing gap, and the processing process is relatively simple.
[0015] In some embodiments, the steel bar torsion correction mechanism further includes a mounting seat, to which an adjustment shaft is connected via a threaded pair, and the movable torsion wheel is rotatably disposed on the adjustment shaft.
[0016] According to the above technical solution, since the adjustment shaft is connected to the mounting seat via a threaded pair, and the movable torsion wheel is rotatably arranged on the adjustment shaft, the axial position of the movable torsion wheel can be infinitely adjusted by screwing the adjustment shaft, the adjustment accuracy is high, and the adjustment force of the torsion steel bars can be accurately controlled.
[0017] In some embodiments, the movable torsion wheel is connected to the adjustment shaft via a bearing.
[0018] According to the above technical solution, by setting the bearing, the rotation resistance between the movable torsion wheel and the adjustment shaft can be reduced, and the wear of both can be reduced, thereby increasing the service life of both.
[0019] In some embodiments, a pre-tightening member is further provided between the adjusting shaft and the mounting seat, and the pre-tightening member is used to push the adjusting shaft along the axial direction.
[0020] According to the above technical solution, by providing a preload, an axial pushing force can be applied to the adjustment shaft, thereby preventing the adjustment shaft from loosening, improving the position accuracy of the movable torsion wheel, and improving the processing quality of the steel bar torsion correction mechanism.
[0021] To achieve the above-mentioned purpose, the steel bar straightening machine proposed in the utility model includes a plurality of steel bar torsion correction mechanisms as described in any one of the above-mentioned embodiments, and the plurality of the steel bar torsion correction mechanisms are arranged in the second radial direction, and in the axial direction, the torsion channels of the plurality of the steel bar torsion correction mechanisms are staggered so that any of the torsion channels is opposite to the plurality of the passing gaps.
[0022] In the technical solution provided by the utility model, multiple steel bar torsion correction mechanisms are arranged in the second radial direction, and each torsion channel is staggered in the axial direction, so that the torsion channel of each steel bar torsion correction mechanism can process one steel bar, and the other parts of the twisted steel bar pass through multiple gaps. Adjusting the position of the torsion wheel of any steel bar torsion correction mechanism will not affect other steel bars, thereby realizing multi-line correction of multiple steel bars and improving the processing efficiency of the steel bar straightening machine.
[0023] In some embodiments, the two torsion wheels in the steel bar torsion correction mechanism include a movable torsion wheel and a fixed torsion wheel;
[0024] The multiple movable twisting wheels in the steel bar straightening machine are located on the same side of the first radial direction.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] It should be noted that if a directional indication is involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0037] At present, when the roller-type steel bar straightening machine processes steel bar coils, the steel bars are affected by the reverse bending deformation force of the steel bars during the traction process. In severe cases, it will cause axial torsion of the steel bars, thereby affecting the straightness of the steel bar straightening and the qualified rate of the stirrup finished products.
[0038] In view of this, the utility model proposes a steel bar torsion correction mechanism, a steel bar straightening machine and a steel bar processing production line, aiming to solve the problem of poor straightness of steel bars processed by the existing roller type steel bar straightening machine.
[0039] in, Figure 1 A structural schematic diagram of an embodiment of a steel bar straightening machine provided by the utility model; Figure 2 for Figure 1 A side structural diagram of an embodiment of a steel bar torsion correction mechanism; Figure 3 for Figure 1 A schematic cross-sectional structure diagram of an embodiment of a steel bar torsion correction mechanism in FIG.
[0040] See also Figure 1 to Figure 2 The steel bar torsion correction mechanism proposed by the utility model is used for a steel bar straightening machine. The steel bar torsion correction mechanism includes two torsion wheels 1. The two torsion wheels 1 are aligned in a first radial direction and are rotatably arranged along an axial axis; in the axial direction, the torsion wheel 1 has a torsion section 11 and a passing section 12. The two passing sections 12 are arranged at intervals to form a passing gap 12a. The passing gap 12a is used for allowing at least one steel bar to pass through. The two torsion sections 11 are aligned, and each torsion section 11 is formed with a torsion annular groove 11a. A torsion channel 11b is defined between the two torsion annular grooves 11a. The torsion channel 11b is used for allowing a single twisted steel bar to pass through after correction; the position of at least one torsion wheel 1 in the axial direction is adjustable.
[0041] It should be noted that the torsion wheel 1 usually has a cross-section, and its radial direction can be various directions within the cross-section, the first radial direction is one of the directions, and the axial direction refers to the extension direction of the axis of the torsion wheel 1; in this embodiment, only the relative positions of the two torsion wheels 1 are limited, and the specific setting positions of each torsion wheel 1 are not limited. The two can be set on the same mounting structure or on different mounting structures; the concept of "segment" is usually relative to the axis, that is, the torsion segment 11 and the through segment 12 are arranged in the axial direction. The through segment 12 involved in this embodiment should not be limited to being understood as a continuous setting, and can also include multiple through segments. Based on this, the torsion segment 11 can be set at the end of the through segment 12, or it can be set between two through segments; the through gap 12a is at least It can allow one steel bar to pass through, and of course it can also allow multiple steel bars to pass through. Of course, the arrangement direction of the multiple steel bars is axial. In order not to be affected by the adjustment position of the torsion wheel 1, the axial size of the through gap 12a should be set large enough to ensure that the torsion segment 11 does not interfere with the steel bars in the through gap 12a; at least one torsion wheel 1 is adjustable in the axial direction, which means that the axial position of one torsion wheel 1 can be adjusted, or the axial positions of both torsion wheels 1 can be adjusted; in the embodiment of the present application, the "annular groove" refers to a groove arranged around the torsion segment 11 or the through segment 12. Since the torsion segments 11 of the two torsion wheels 1 are arranged close to each other, the two torsion annular grooves 11a can define a torsion channel 11b at the closest point, and the torsion channel 11b extends along the second radial direction.
[0042] In the technical solution provided by the utility model, since the two torsion wheels 1 in the steel bar torsion correction mechanism respectively have a torsion section 11 and a passing section 12, and the torsion channel 11b formed by the torsion ring groove 11a on the torsion section 11 can allow the steel bar to pass through, when the steel bar needs to be torsion corrected, by adjusting the axial position of one of the torsion wheels 1, the steel bar can be squeezed in the axial direction by the opposite side walls of the two torsion ring grooves 11a during the process of passing through the torsion channel 11b, thereby applying a corrective torsion force along the circumferential direction of the steel bar, so that the torsional stress inside the steel bar can be released, thereby achieving the purpose of torsion correction of the steel bar, and improving the straightness quality of the steel bar processed by the steel bar straightening machine; not only that, due to the setting of the passing section 12, the passing gap 12a formed therein can straighten and pass other steel bars, which can improve the processing efficiency of the steel bar straightening machine. At the same time, when the torsion wheel 1 is adjusted in the axial direction, the steel bar in the passing gap 12a is subjected to a smaller axial force, which does not affect the passage of the steel bar therein.
[0043] In some embodiments, the torsion annular groove 11 a has two opposite annular groove side walls, and the distance between the two annular groove side walls gradually increases in a first radial direction away from the torsion wheel 1 .
[0044] According to the above technical solution, in order to adapt to the axial misalignment of the two torsion wheels 1, the spacing between the two annular groove side walls is set to gradually increase, so that the extrusion force of the annular groove side walls on the steel bars is offset in the tangential direction of the steel bars, thereby providing the largest possible circumferential correction torque, thereby improving the correction efficiency of the twisted steel bars.
[0045] In some embodiments, the two twisting wheels 1 include a movable twisting wheel 1a and a fixed twisting wheel 1b. A positioning ring groove 12b is formed on the passing section 12 of the fixed twisting wheel 1b. The positioning ring groove 12b is used to accommodate the steel bar.
[0046] According to the above technical solution, due to the setting of the positioning ring groove 12b, the steel bar can always remain in the positioning ring groove 12b when passing through the national gap, further reducing the impact of the active torsion wheel 1a on the steel bar in the gap 12a when adjusting the axial direction.
[0047] In some embodiments, an annular protrusion 111 is formed at the torsion section 11 of the movable torsion wheel 1 a ; and one of the torsion annular grooves 11 a is formed at the annular protrusion 111 .
[0048] According to the above technical solution, by setting the annular protrusion 111, the torsion ring groove 11a on the movable torsion wheel 1a can actively approach the torsion ring groove 11a on the fixed torsion wheel 1b, which means that in the process of producing the steel bar torsion correction mechanism, it is only necessary to turn the corresponding step on the passing section 12 of the movable torsion wheel 1a, and the fixed torsion wheel 1b can be set as a round shaft, which can meet the formation conditions of the torsion ring groove 11a and the passing gap 12a, and the processing process is relatively simple.
[0049] See also Figure 3 In some embodiments, the steel bar torsion correction mechanism further includes a mounting seat 2, to which an adjustment shaft 3 is connected via a threaded pair, and a movable torsion wheel 1a is rotatably disposed on the adjustment shaft 3.
[0050] It should be noted that the thread pair refers to internal and external threads that mesh with each other. Generally speaking, the external thread is formed on the shaft and the internal thread is formed in the hole. Based on this, it can be set that one end of the adjustment shaft 3 is formed with an external thread, and a threaded hole extending in the axial direction is formed on the mounting seat 2, and the adjustment shaft 3 is set in the threaded hole. Of course, a threaded hole can also be set at the end of the adjustment shaft 3, and a screw extending in the axial direction can be set on the mounting seat 2. The specific type is not limited in this embodiment.
[0051] According to the above technical solution, since the adjustment shaft 3 is connected to the mounting seat 2 through a threaded pair, and the movable torsion wheel 1a is rotatably set on the adjustment shaft 3, the axial position of the movable torsion wheel 1a can be infinitely adjusted by screwing the adjustment shaft 3. The adjustment accuracy is high, and the adjustment force of the torsion steel bar can be accurately controlled.
[0052] In some embodiments, the movable torsion wheel 1 a is connected to the adjustment shaft 3 via a bearing 4 .
[0053] According to the above technical solution, by disposing the bearing 4, the rotation resistance between the movable twisting wheel 1a and the adjustment shaft 3 can be reduced, and the wear of both can be reduced, thereby increasing the service life of both.
[0054] In some embodiments, a pre-tightening member 5 is further provided between the adjusting shaft 3 and the mounting seat 2 , and the pre-tightening member 5 is used to push the adjusting shaft 3 in the axial direction.
[0055] It should be noted that the function of the preload member 5 is to provide an axial pushing force for the adjustment shaft 3 . There are many components that can achieve this function, such as rubber components. The specific structure of the preload member 5 is not limited in this embodiment.
[0056] According to the above technical solution, by setting the preload member 5, an axial pushing force can be applied to the adjustment shaft 3, thereby preventing the adjustment shaft 3 from loosening, improving the position accuracy of the movable torsion wheel 1a, and improving the processing quality of the steel bar torsion correction mechanism.
[0057] In some embodiments, the preload element 5 includes a preload spring 51 .
[0058] According to the above technical solution, the purchase cost of the preload spring 51 is low, and the rebound performance is good, which can achieve a good preload effect.
[0059] In addition, to achieve the above-mentioned purpose, the utility model also provides a steel bar straightening machine, which includes a plurality of steel bar torsion correction mechanisms as described in the above-mentioned technical solution, and the plurality of steel bar torsion correction mechanisms are arranged in the second radial direction, and in the axial direction, the torsion channels 11b of the plurality of steel bar torsion correction mechanisms are arranged in a staggered manner so that any torsion channel 11b is opposite to the plurality of through gaps 12a. It should be noted that the detailed structure of the steel bar torsion correction mechanism of the steel bar straightening machine can refer to the embodiment of the above-mentioned steel bar torsion correction mechanism, and will not be repeated here; since the above-mentioned steel bar torsion correction mechanism is used in the steel bar straightening machine of the utility model, the embodiment of the steel bar straightening machine of the utility model includes all the technical solutions of all the embodiments of the above-mentioned steel bar torsion correction mechanism, and the technical effects achieved are also exactly the same.
[0060] It should be noted that, in the present embodiment, as long as the torsion channel 11b formed on each steel bar torsion correction mechanism extends along the second direction, there is no limitation on which specific torsion wheel 1 can make axial position adjustment; at the same time, since the multiple torsion channels 11b are staggeredly arranged along the axial direction, a single steel bar can be in the passing gap 12a formed on other steel bar torsion correction mechanisms before and after passing through the torsion channel 11b, and thus will not be affected by the position adjustment of the torsion wheels 1 in other steel bar torsion correction mechanisms.
[0061] In the technical solution provided by the utility model, multiple steel bar torsion correction mechanisms are arranged in the second radial direction, and each torsion channel 11b is staggered in the axial direction, so that the torsion channel 11b of each steel bar torsion correction mechanism can process one twisted steel bar, and the other parts of the twisted steel bar pass through multiple gaps 12a. Adjusting the position of the torsion wheel 1 of any steel bar torsion correction mechanism will not affect other steel bars, so that multi-line correction of multiple twisted steel bars can be achieved, thereby improving the processing efficiency of the steel bar straightening machine.
[0062] In some embodiments, the two twisting wheels 1 in the steel bar twisting and correction mechanism include a movable twisting wheel 1a and a fixed twisting wheel 1b; the multiple movable twisting wheels 1a in the steel bar straightening machine are located on the same side of the first radial direction.
[0063] According to the above technical solution, multiple movable twisting wheels 1a are arranged on the same side, which is convenient for utilizing the installation space of the steel bar straightening machine and is also beneficial for operators to adjust each movable twisting wheel 1a.
