Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a matching tapered device for a plate rolling machine. Background Technology

[0002] A plate rolling machine is a machine that uses rotating work rollers to continuously bend metal sheets. The common symmetrical three-roll plate rolling machine mainly rolls the sheet through upper and lower rollers located in the same symmetrical plane. It has a simple structure and is suitable for rolling cylindrical bodies.

[0003] However, when it is necessary to roll a conical cylinder, since the large and small ends of the cone have different diameters, the upper and lower rollers are required to form an asymmetrical roller gap in the feeding direction of the sheet material, that is, the gap is large at one end and small at the other end. Furthermore, during the entire rolling process, the axis of the rollers needs to maintain a specific inclination relationship with the generatrix of the cone.

[0004] Traditional symmetrical three-roll plate bending machines cannot directly meet the tilting requirements of the upper roll. The upper roll can usually only perform vertical lifting and lowering movements, making it difficult to adjust the required tilt angle and inconvenient for tapering operations. Summary of the Invention

[0005] The purpose of this utility model is to provide a matching tapered device for a plate rolling machine. Through the upper roller assembly, the tilt angle of the upper roller body can be adjusted, which not only facilitates the placement of steel plates between the upper roller body and the lower roller, but also enables tapered operation due to the different gaps between the two ends of the upper roller body and the lower roller, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a matching tapered device for a plate rolling machine, comprising a plate rolling machine frame, bearing seats at both ends of the plate rolling machine frame, a stop block assembly for limiting the position on the inner side of the bearing seats, two sets of lower rollers on the side of the stop block assembly, and an upper roller assembly installed above the lower rollers.

[0007] The upper roller assembly includes a support frame welded above the bearing housing, and the upper roller body is movably installed inside the support frame;

[0008] The stop assembly includes a slider base fixed to the side of the bearing seat, and a trapezoidal stop is installed above the slider base.

[0009] Preferably, the upper roller assembly further includes spherical roller bearings installed at both ends of the upper roller body, and the spherical roller bearings are provided with a support base on their exterior.

[0010] Preferably, the support base is slidably installed inside the support frame, and fixing plates are installed on both the upper and lower sides of the support base.

[0011] Preferably, the fixing plate is internally threaded with an adjusting screw, and a hexagonal nut is welded to the side of the adjusting screw away from the support base, while a lifting component is welded to the side of the adjusting screw close to the support base.

[0012] Preferably, a limiting plate is welded to one end of the support base through the support frame, and a wear-resistant coating is provided on the surface of the upper roller body.

[0013] Preferably, the stop assembly further includes a guide groove disposed between the slider base and the trapezoidal stop, and fixed structural components are welded to both the left and right sides of the trapezoidal stop.

[0014] Preferably, a power motor is bolted to the side of one of the bearing housings.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The upper roller assembly allows for adjustment of the tilt angle of the upper roller body, which not only facilitates the placement of steel plates between the upper roller body and the lower roller, but also enables tapering operations due to the different gaps between the two ends of the upper roller body and the lower roller.

[0017] 2. By using the set stop block assembly, trapezoidal stops of appropriate size can be replaced as needed. The resistance of the trapezoidal stops, in conjunction with the tiltable upper roller body, enables the cone rolling. Attached Figure Description

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A tapered device for a plate rolling machine includes a plate rolling machine frame 1, bearing seats 6 at both ends of the plate rolling machine frame 1, a stop block assembly 3 for limiting the position is provided on the inner side of the bearing seat 6, two sets of lower rollers 5 are provided on the side of the stop block assembly 3, and an upper roller assembly 4 is installed above the lower rollers 5.

[0028] The upper roller assembly 4 includes a support frame 401 welded above the bearing housing 6, and the upper roller body 409 is movably installed inside the support frame 401;

[0029] The stop assembly 3 includes a slider base 301 fixed to the side of the bearing seat 6, and a trapezoidal stop 302 is installed above the slider base 301.

[0030] The upper roller assembly 4 also includes spherical roller bearings 404 installed at both ends of the upper roller body 409. A support base 403 is provided on the outside of the spherical roller bearings 404. The support base 403 is slidably installed inside the support frame 401. The distance between the support bases 403 is greater than the distance between the two sets of support frames 401. Fixing plates 405 are installed on both the upper and lower sides of the support base 403. An adjusting screw 408 is threaded inside the fixing plate 405. A hexagonal nut 407 is welded to the side of the adjusting screw 408 away from the support base 403. A lifting component 406 is welded to the side of the adjusting screw 408 close to the support base 403. A limit plate 402 is welded to one end of the support base 403 that passes through the support frame 401. The surface of the upper roller body 409 is provided with a wear-resistant coating 410. The support base 403 can not only be raised and lowered inside the support frame 401, but also move laterally to achieve the tilting of the upper roller body 409.

[0031] By adopting the above technical solution, during tapering, the hexagonal nut 407 is rotated using a hexagonal wrench. The hexagonal nut 407 drives the adjusting screw 408 to rotate on the fixed plate 405. The lifting component 406 moves along the axis of the adjusting screw 408. A rubber pad is attached to the surface of the lifting component 406, and the rubber pad can contact the support base 403. Thus, the height of the support base 403 can be adjusted by the two sets of lifting components 406. At the same time, the support base 403 moves laterally inside the support frame 401, and the limiting plate 402 can prevent the support base 403 from detaching. Support frame 401, at this time the upper roller body 409 is tilted. When the steel plate enters between the upper roller body 409 and the lower roller 5, due to the different gaps between the two ends of the upper roller body 409 and the lower roller 5, the plate is gradually rolled into a cone shape under the joint action of the upper roller body 409 and the lower roller 5, realizing the cone rolling operation. Through the set upper roller assembly 4, the tilt angle of the upper roller body 409 can be adjusted, which not only makes it convenient to place the steel plate between the upper roller body 409 and the lower roller 5, but also enables the cone rolling operation due to the different gaps between the two ends of the upper roller body 409 and the lower roller 5.

[0032] Specifically, such as Figure 2 As shown, the stop assembly 3 also includes a guide groove 304 disposed between the slider base 301 and the trapezoidal stop 302. The trapezoidal stop 302 has a fixing structure 303 welded on both the left and right sides. The fixing structure 303 is installed on the top of the slider base 301 by bolts. The slider base 301 is welded to the inner side of the bearing seat 6 near the lower roller 5.

[0033] One of the bearing housings 6 has a power motor 2 bolted to its side. The power output end of the power motor 2 is connected to the drive gear. Two sets of driven gears are meshed on both sides of the drive gear. The two sets of driven gears are fixedly connected to the lower roller 5 through a coupling. The power motor 2 drives the two sets of lower rollers 5 to rotate under the action of the gear set. The upper roller body 409 is a passive roller. It is not constrained by the transmission gear and can be easily tilted. The cone winding operation is achieved by rotating the lower roller 5 alone.

[0034] By adopting the above technical solution, before tapering, a trapezoidal stop 302 adapted to the tapered size is installed. The trapezoidal stop 302 abuts against the small end of the steel plate. During installation, the trapezoidal stop 302 slides along the guide groove 304 above the slider base 301. The trapezoidal stop 302 moves to the vertical plane where the axis of the upper roller body 409 is located. Since the trapezoidal stop 302 is installed on the slider base 301, under the resistance of the trapezoidal stop 302, the steel plate can only move along the trajectory required for tapering to achieve the purpose of tapering. Through the set stop assembly 3, the trapezoidal stop 302 of appropriate size can be replaced as needed. With the resistance of the trapezoidal stop 302, tapering is achieved in conjunction with the tiltable upper roller body 409.

[0035] Working principle: The trapezoidal stop 302, which is adapted to the tapered installation dimensions, slides along the guide groove 304 above the slider base 301. The trapezoidal stop 302 moves to the vertical plane where the axis of the upper roller body 409 is located. Since the trapezoidal stop 302 is installed on the slider base 301, the hexagonal nut 407 is rotated by a hexagonal wrench. The hexagonal nut 407 drives the adjusting screw 408 to rotate on the fixed plate 405. The lifting component 406 moves along the axis of the adjusting screw 408. Rubber pads are attached to the surface of 06, and the rubber pads can contact the support base 403. The height of the support base 403 can be adjusted by two sets of lifting parts 406. At the same time, the support base 403 moves laterally inside the support frame 401. The limiting plate 402 can prevent the support base 403 from detaching from the support frame 401. At this time, the upper roller body 409 tilts, and the steel plate is located between the upper roller body 409 and the lower roller 5. The trapezoidal stop 302 abuts against the small end of the steel plate, and the rotatable lower roller 5 is used to achieve the cone rolling.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
