Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal sheet processing equipment technology, specifically to a device for correcting the flange of an arc plate based on a four-roll plate rolling machine. Background Technology
[0002] Currently, after the curved plate is rolled into shape, the two sides of the rolled plate always show a phenomenon of outward folding and non-perpendicularity. It is necessary to correct the horizontal surface and the vertical side surface of the curved plate. Since the width of the curved plate is not uniform, the correction equipment needs to be able to adapt to the width of the curved plate when correcting a batch of curved plates. Among the production equipment of curved plates, the four-roll plate rolling machine is the most common. By adding a correction structure to the folding point of the existing equipment based on the four-roll plate rolling machine, it is not only convenient to correct the folding point of the curved plate, but also to reduce the cost of building a separate correction equipment. Therefore, we propose a correction device for the folding point of curved plates based on a four-roll plate rolling machine. Utility Model Content
[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a correction device for the flange of an arc plate based on a four-roll plate rolling machine, which can solve the above problems.
[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0005] A device for correcting the flange of an arc plate based on a four-roll plate rolling machine includes a frame, an upper roller and a lower roller installed inside the frame and vertically aligned, side rollers distributed on both sides of the lower roller, and an arc plate. Two upper roller clamps are fitted on the circumferential surface of the upper roller, two lower roller clamps are fitted on the circumferential surface of the lower roller, and two side roller clamps are fitted on the circumferential surface of the side rollers. Both the upper roller clamps and the lower roller clamps include two semi-circular clamps A, and the side roller clamps include two semi-circular clamps B. The ends of the two semi-circular clamps B are integrally formed with semi-circular retaining rings. Screws for fastening are provided at the upper and lower ends of the two semi-circular clamps A and B. The arc plate includes flanges on both sides.
[0006] Furthermore, the outer surface of the semicircular hoop A and the outer surface of the semicircular retaining ring are both threaded with lifting eye bolts for hoisting.
[0007] Furthermore, the semi-circular retaining ring is in close contact with the vertical end of the outer side of the flange.
[0008] Furthermore, shallow grooves are provided on the inner circumference surfaces of both semicircular hoop A and semicircular hoop B, and rubber ring pads for increasing contact friction are embedded inside the shallow grooves.
[0009] Furthermore, shallow grooves are provided on the inner wall of the shallow groove, and rubber teeth are provided on the side of the rubber ring gasket facing the shallow groove.
[0010] The beneficial effects of this utility model are as follows: The upper roller clamp and the lower roller clamp of this application device perform horizontal correction on the horizontal surface of the flange of the arc plate, and perform vertical correction on the vertical surface of the outer side of the flange of the arc plate through the retaining ring area of the side roller clamp. At the same time, the upper, lower and side roller clamps are all assembled by a semi-circular splicing method, which can be assembled at any position of the roller body. It can not only perform flange correction on the side of the arc plate with different widths, but also has strong applicability. In addition, it is equipped with lifting eye screws for easy assembly and disassembly.
[0011] Rubber rings are installed on the inner wall of the semi-circular hoop to increase the friction between the hoop and the roller surface, and to protect the roller surface, reducing indentations and wear. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] like Figure 1-5 As shown, this utility model discloses a correction device for the flange of an arc plate based on a four-roll plate rolling machine. It includes a frame, an upper roller 1 and a lower roller 3 installed inside the frame and vertically aligned, side rollers 4 distributed on both sides of the lower roller 3, and an arc plate 2. Two upper roller clamps 5 are fitted on the circumferential surface of the upper roller 1, two lower roller clamps 6 are fitted on the circumferential surface of the lower roller 3, and two side roller clamps 7 are fitted on the circumferential surface of the side roller 4. Both the upper roller clamps 5 and the lower roller clamps 6 include two semi-circular clamps A501, and the side roller clamps 7 include two semi-circular clamps B701. The ends of the two semi-circular clamps B701 are integrally formed with semi-circular retaining rings 702. The upper and lower ends of the two semi-circular clamps A501 and B701 are provided with screws 502 for fastening. The arc plate 2 includes flanges 201 on both sides.
[0023] Example 1: The clamps of the upper, lower, and side roller clamps are all made of 40Cr alloy steel and are subjected to quenching and tempering + surface hardening treatment with a hardness of HRC50 to ensure the service life of the clamp tooling and realize the batch shaping of the curved plate edges.
[0024] To prevent interference between the lower roller 3 and the side roller 4 during operation, the axial distance between the side roller 4 and the lower roller 3 is controlled at 2~3mm. The upper roller 1 and the lower roller 3 rotate in opposite directions, while the lower roller 3 and the side roller 4 rotate in the same direction. The upper roller 1, the lower roller 3 and the side roller 4 are all driven by a motor and a sprocket system.
[0025] First, hoist the upper roller clamp 5 and lower roller clamp 6 to the vicinity of the upper roller 1 and lower roller 3. After pre-fixing with screws, remove the lifting eye bolt 503. Adjust according to the position of the flange 201 of the arc plate 2 so that the upper roller clamp 5 and lower roller clamp 6 are vertically aligned with the flange 201 on both sides of the arc plate 2. Then tighten the screw 502. During the process, the rubber ring gasket 8 gradually presses against the roller body surface, thereby locking the position of the upper roller clamp 5 and lower roller clamp 6. Similarly, move the side... The roller clamp 7 is hoisted to the vicinity of the side roller 4. The retaining ring area formed by the semi-circular retaining ring of the side roller clamp 7 is vertically aligned with the vertical end of the outer side of the flange 201 of the arc plate 2. As the arc plate 2 passes through the upper roller 1 and the lower roller 3, the retaining ring area of the side roller clamp 7 comes into contact with the vertical end of the outer side of the flange 201 of the arc plate 2, thereby correcting the verticality. The upper roller clamp 5 cooperates with the lower roller clamp 6 to correct the horizontal surface of the flange 201 of the arc plate 2.
[0026] In the preferred technical solution, the outer surface of the semicircular hoop A501 and the outer surface of the semicircular retaining ring 702 are both threaded with lifting eye bolts 503 for lifting. The lifting eye bolts 503 consist of a lifting eye and a bolt, which facilitates the lifting of the hoop.
[0027] In the preferred technical solution, shallow grooves 9 are provided on the inner circumferential surfaces of both the semicircular hoop A501 and the semicircular hoop B701. A rubber ring pad 8 for increasing contact friction is embedded inside the shallow groove 9. Shallow grooves are provided on the inner wall of the shallow groove 9. Rubber teeth 801 are provided on the side of the rubber ring pad 8 facing the shallow groove 9. The shallow groove and the rubber teeth 801 can improve the stability of the rubber ring pad 8 in the shallow groove 9, thereby improving the assembly stability of the semicircular hoop and the roller.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
