TECHNICAL FIELD
[0001] The utility model relates to a steel bar processing technical field, concretely relates to a rolling device for producing three-side ribbed steel bar. BACKGROUND
[0002] The ribbing is usually rolled on the surface of the steel bar during the processing, because the ribbing on the surface of the steel bar forms mechanical engagement with the concrete, when the concrete is subjected to external force, the ribbing can effectively prevent the relative sliding between the steel bar and the concrete, so that they work together to bear the external force, greatly improving the bonding strength of the steel bar and the concrete. In addition, the existence of the ribbing increases the contact area of the steel bar and the concrete, and forms many tiny unevennesses on the contact surface, thereby increasing the friction, which can better transmit stress when the structure is under stress, making the combination between the steel bar and the concrete more closely. The ribbing of the ribbed steel bar can better combine with the concrete within the anchoring length range, providing sufficient anchoring force to prevent the steel bar from being pulled out or sliding at the anchoring position, ensuring the safety and stability of the structure.
[0003] At present, the steel bar is usually rolled with ribbing on three sides. The traditional three-side ribbed steel bar rolling process is a drawing and scoring rolling method, and the rolling roller transmission mode is passive and without power. The bearing needs to be assembled in the inner heart of the rolling roller, causing the bearing to be small and compact, and the transmission shaft diameter to be small. Due to the design structure, it cannot bear large rolling force, resulting in errors in the geometric size of the rolled workpiece, and the rolled crescent rib cannot meet the national standard requirements, the anchoring performance with the concrete is poor, the concrete bearing capacity is reduced, and there are potential quality problems of the building.

DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0032] The principles and spirits of the utility model will be explained in detail below with reference to several representative embodiments of the utility model.
[0033] Embodiment 1 of the rolling device for producing three-side ribbed steel bars provided by the utility model:
[0034] As shown in Figure 1 and Figure 2 A rolling device for producing three-side ribbed steel bars comprises a base 1, three groups of rolling units installed on the base 1, a guide mechanism installed on the base 1 and an elevator 6 installed on the base 1.
[0035] Among them, as shown in Figure 1 As shown, the base 1 is a cuboid box, including vertical plates, a top plate, a bottom plate and side plates, the vertical plates are arranged in parallel and spaced apart, the top plate and the bottom plate are parallel and connected to the top end and the bottom end of the two vertical plates respectively; the side plate has the largest area and is connected with the two vertical plates, the top plate and the bottom plate. One of the two vertical plates is provided with two fans 2 arranged in an upper and lower spaced apart manner, and the other vertical plate is provided with an air outlet 21 corresponding to the position of the fan 2.
[0036] The structures of the three groups of rolling units are the same, and one of the groups of rolling units is described in detail in the embodiment. The rolling unit includes a motor driving assembly 4, a universal joint coupling 3, a bearing seat 5, a bearing, a transmission shaft 13 and a roller 9, wherein the bearing is installed in the bearing seat 5, one end of the transmission shaft 13 is connected with the end flange of the universal joint coupling 3 through a flange, the other end of the transmission shaft 13 is coaxially arranged through the bearing and the roller 9 and fixed with the roller 9. The assembly mode of the transmission shaft 13 and the roller 9 is a prior art, for example, a key groove and key connection mode can be used, of course, the roller 9 can be sleeved on the transmission shaft 13 and abut against the shaft shoulder of the transmission shaft 13, external threads are processed on the transmission shaft 13, an end plate is pressed at the end surface of the roller 9 in a threaded cooperation mode with the transmission shaft 13, and the end plate is fixed with the roller 9 through bolts. In actual application, the mounting mode is not limited to the above. The motor driving assembly 4 includes a driving motor and a speed reducer, the output end of the speed reducer is connected with the end of the universal joint coupling 3 away from the transmission shaft 13, and the driving motor drives the universal joint coupling 3 to rotate through the speed reducer when working, and then drives the roller 9 to rotate through the transmission shaft 13, so that the roller 9 can roll the ribs on the surface of the steel bar. As can be seen, the roller 9 in the embodiment is driven to rotate by the driving motor, and the ribs on the surface of the steel bar are rolled by the driving motor in a driving mode. This form can move the bearing from the inside of the roller 9 to the outside, at this time the bearing is fixed in a separate bearing seat 5, and a larger size bearing and transmission shaft 13 can be correspondingly arranged, so that the roller 9 can bear a larger rolling force, the geometric size of the rolled steel bar is more accurate, and the shape of the rolled crescent rib is more full, and the anchoring performance with concrete is good.
[0037] In the embodiment, the elevator 6 is a worm gear screw rod elevator, which is fixed on the side plate through an elevator support 8. The elevator 6 includes an elevator motor, a worm connected with the output shaft of the elevator motor, a worm gear meshing with the worm, and a lifting screw coaxial with the worm gear, the worm gear has a central threaded hole, and the lifting screw is threadedly connected with the worm gear. One end of the lifting screw close to the bearing seat 5 is connected with a fixed plate 7, and the fixed plate 7 is connected with the bearing seat 5. When the elevator motor works, the worm rotates to drive the worm gear to rotate, and then drives the lifting screw to move linearly in a direction perpendicular to the axis of the roller 9. Since the lifting screw is fixed with the bearing seat 5 through the fixed plate 7, the lifting screw can drive the bearing seat 5 and the roller 9 to move linearly. Under the action of the universal joint coupling 3, the power of the driving motor can be transmitted to the transmission shaft 13, and then the normal rotation of the roller 9 is ensured.
[0038] To ensure the stability of the bearing seat 5 movement, as shown in Figure 2 and Figure 3 , the bearing seat support 12 is fixed on the side plate corresponding to the position of each bearing seat 5, and the bearing seat support 12 is provided with a sliding groove 19 matched with the guide sliding of the fixed plate 7. The size of the sliding groove 19 is matched with the fixed plate 7, and a larger sliding groove 19 does not need to be opened on the bearing seat support 12, which correspondingly reduces the volume of the bearing seat support 12 and saves cost.
[0039] As shown in Figure 2 , in the rolling unit, the axis angle between any two adjacent rolling rollers 9 is 120°, and the axis angle between any two adjacent transmission shafts 13 is 60°. The three rolling rollers 9 form a rolling channel for the steel bar to pass through. When the steel bar passes through the rolling channel, the three rolling rollers 9 can roll ribs on the surface of the steel bar from three sides.
[0040] Since the rolling roller 9 can adjust the position under the action of the elevator 6, when the three rolling rollers 9 are adjusting the position, the three rolling rollers 9 can simultaneously roll ribs on the steel bar, and the size of the rolling channel can be adjusted to meet the rolling of steel bars of different diameters.
[0041] The guide mechanism is used for guiding the steel bar. In the embodiment, as shown in Figure 2 and Figure 4 , the guide mechanism includes a mounting seat 11, a guide seat 10, a guide block 14 and a guide wheel 15. The guide seat 10 is provided with a through port penetrating the guide seat 10, and three guide grooves 20 communicating with the through port. The guide block 14 is provided with three guide grooves 20 corresponding to the guide grooves 20. The three guide blocks 14 are arranged at an angle of 120°, and the guide wheel 15 is arranged corresponding to the guide block 14. The three guide wheels 15 are rotatably arranged at the same end of the three guide blocks 14, and the three guide wheels 15 form a guide channel 18 for guiding the steel bar to pass through. The guide wheel 15 is used for guiding the steel bar, and the guide channel 18 is coincident with the center axis of the rolling channel. The steel bar passes through the guide channel 18 and then enters the rolling channel to roll ribs.
[0042] To adapt to the position adjustment of the roller 9, in the embodiment, the position of the guide block 14 is adjustable in the direction perpendicular to the extension direction of the corresponding guide slot 20. Specifically, the guide seat 10 is provided with a through hole corresponding to each guide slot 20, and the through hole is spaced apart along the extension direction of the guide slot 20. Each through hole is provided with an adjusting nut 17 at the hole on the outer side of the guide seat 10, the adjusting nut 17 is threadedly connected with an adjusting bolt 16, and the end of the adjusting bolt 16 is rotatably connected with the corresponding guide block 14. The rotating assembly can be a rotating bearing arranged in the guide block 14, and the head of the adjusting bolt 16 is processed into a light pole section connected with the rotating bearing. When the adjusting bolt 16 is screwed, the adjusting bolt 16 moves towards the through hole, thereby pushing the guide block 14 to move in the guide slot 20 along the direction perpendicular to the length direction of the guide slot 20. When the guide block 14 moves, the guide wheel 15 rotatably connected with the guide block 14 also moves, thereby adjusting the size of the guide channel 18, so that the guide channel 18 can guide the steel bars of different diameters to pass through, and meanwhile, the three guide wheels 15 can be in contact with the steel bars, so that the geometric size of the rolled workpiece is accurate.
[0043] In addition, since different specifications of steel bars require different guide and rolling distances between the guide seat 10 and the roller 9 when the ribs are rolled, the guide seat 10 and the mounting seat 11 are slidably connected, that is, the guide seat 10 can move relative to the mounting seat 11, thereby adjusting the mounting distance between the guide seat 10 and the roller 9.
[0044] The rolling device for producing three-sided ribbed steel bars can roll the steel bars with accurate geometric size, and ensure the anchoring performance between the rolled steel bars and the concrete. Meanwhile, the rolling device can also adapt to the rolling of steel bars with different diameters, and the application range is improved.
