Technical Field

[0001] The utility model belongs to the technical field of straightening machines, and in particular relates to a straightening roller locking device. Background Art

[0002] A straightening machine is a device used in the metal processing industry to correct the straightness error of metal materials, such as profiles, bars, pipes, wires, etc. The working principle of the straightening machine is to apply a certain pressure and bending force to make the material plastically deform when passing through the straightening machine, thereby eliminating defects such as bending and twisting of the material to achieve a straightening effect. The straightening machine is constantly advancing with the advancement of metal material processing technology, the increase in industrial production needs, and the strengthening of automation, intelligence, energy conservation and environmental protection requirements. However, in the process of straightening steel sections, due to the small locking force of the straightening roller and the vibration of the equipment during the straightening process, the straightening roller is prone to slipping, resulting in inaccurate straightening accuracy, which seriously affects the product quality and the service life of the straightening machine. Therefore, a straightening roller locking device that can achieve a good locking function for the straightening roller is needed. Utility Model Content

[0007] A further improvement of the technical solution of the utility model is that the locking nut comprises an inner ring and an outer ring connected to the inner ring along a circumferential key.

[0008] A further improvement of the technical solution of the utility model is that two layers of stepped grooves are provided at the center of the C-shaped circular ring plate, and the groove 1 at the top layer has the same height as the grooves 2 at both ends of the opening.

[0009] A further improvement of the technical solution of the utility model is that limiting steps are symmetrically arranged on the shaft rod, and when the C-shaped circular ring plate is placed on the shaft rod, the limiting steps can be located in the groove three of the bottom layer of the step groove to limit the axial position of the C-shaped circular ring plate.

[0016] The present invention is further described in detail below in conjunction with the embodiments:

[0017] like Figure 1As shown, a straightening roller locking device includes a tightening mechanism arranged at the end of the straightening roller for tightening the straightening roller. The straightening roller includes a roller shaft 1, a roller sleeve 2 sleeved on the outside of the roller shaft 1, and a roller ring 3 sleeved on the outside of the roller sleeve 2. The roller shaft 1 and the roller sleeve 2 are connected by a key arranged along the circumference of the roller shaft 1. Two 90×45 keys can be symmetrically arranged along the circumference of the roller shaft 1, so that the roller sleeve 2 is fixedly sleeved on the roller shaft 1. The tightening mechanism includes an annular limiting component sleeved on the end of the roller sleeve 2, a hydraulic locking cylinder 5 connected to the roller shaft 1 through a shaft 4, a bolt 9 arranged at the end of the hydraulic locking cylinder 5, and a C-shaped circular ring plate 6 arranged on the shaft 4. The C-shaped circular ring plate 6 is arranged between the annular limiting component and the hydraulic locking cylinder 5, wherein the annular limiting component axially fixes the roller ring 3 on the roller sleeve 2, and the C-shaped circular ring plate 6 presses the annular limiting component at the end of the roller sleeve 2 under the action of the hydraulic locking cylinder 5, thereby limiting the axial displacement of the roller ring 3 on the roller sleeve 2.

[0018] The annular limiting component includes a pressure ring 7 sleeved on the end of the roller sleeve 2 and a locking nut 8 that axially fixes the roller ring 3 on the roller sleeve 2 through the pressure ring 7. The hydraulic locking cylinder 5 is provided with a disc spring 5-1 that can tighten the C-shaped circular ring plate 6. Under the action of the hydraulic locking cylinder 5, the disc spring 5-1 compresses and locks the C-shaped circular ring plate 6 so that the C-shaped circular ring plate 6 presses the locking nut 8. The diameter of the C-shaped circular ring plate 6 is the same as the diameter of the locking nut 8, thereby achieving a complete fixing effect on the straightening roller. The locking nut 8 is divided into an inner ring and an outer ring. The circumferential direction of the two parts is positioned by a key so that they cannot rotate relative to each other.

[0019] like Figure 2 and Figure 3 As shown, the C-shaped annular plate 6 is detachably arranged on the shaft 4 of the hydraulic locking cylinder 5, and the C-shaped annular plate 6 is clamped on the shaft 4 of the hydraulic locking cylinder 5 through an opening, and a stepped groove is arranged on the side of the C-shaped annular plate 6 that contacts the hydraulic locking cylinder 5 at the center position of the circle of the C-shaped annular plate 6, and grooves 6-2 communicating with the top groove 1 6-1 of the stepped groove are arranged at both ends of the opening of the C-shaped annular plate 6, so that the gap between the C-shaped annular plate 6 and the hydraulic locking cylinder 5 is increased, and iron oxide and turbid water can flow out smoothly during straightening operations. The increase in the gap effectively avoids the occurrence of blockage problems, facilitates the disassembly and replacement of the C-shaped annular plate 6, and can be lifted out at one time by a special hoist, thereby improving the efficiency of roller replacement and saving process adjustment time. Preferably, two layers of stepped grooves are arranged at the center position of the C-shaped circular ring plate 6, and the groove one 6-1 on the top layer of the stepped groove has the same height as the groove two 6-2 at both ends of the opening of the C-shaped circular ring plate 6. The limiting steps 10 are symmetrically arranged on the shaft rod 4. When the C-shaped circular ring plate 6 is placed on the shaft rod 4, the limiting steps 10 can be located in the groove three 6-3 on the bottom layer of the stepped groove to axially limit the C-shaped circular ring plate 6. The limiting steps 10 can axially prevent the C-shaped circular ring plate 6 from sliding outward, but will not affect its inward sliding.
