Description

Technical Field

[0001] This invention relates to the field of plate rolling machine technology, and specifically to a universal plate rolling machine with an upper roller. Background Technology

[0002] The upper roller universal plate rolling machine is a working device used to pre-bend and roll cylindrical and arc-shaped workpieces at both ends of plate materials. It adopts hydraulic transmission for upper roller lifting and horizontal movement (mechanical transmission), driven by lower roller, and has a centralized electrical control system. It can complete the pre-bending and rolling of cylindrical and arc-shaped workpieces at both ends of plate materials in one feeding. It can also perform certain shaping and leveling of metal plates. It has the effects of direct pre-bending, saving time and materials. It is equipped with an NC system control to improve the degree of automation.

[0003] Existing universal plate rolling machines with upper rollers are prone to plate movement during bending and rolling, causing the plate to shift during the bending and rolling process and resulting in substandard finished product quality. Furthermore, after bending and rolling, smaller finished products need to be manually removed from the plate rolling machine, while larger products require crane lifting, which is cumbersome, time-consuming, and labor-intensive. In addition, the plates are prone to collision with the upper and lower rollers of the plate rolling machine during the removal process, causing damage to the rollers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an upper roller universal plate rolling machine, which solves the problems of easy displacement during the bending and rolling process of plates and difficulty in removing finished products.

[0005] A universal plate rolling machine with upper roller, comprising:

[0006] A base plate with two opposing supports arranged on it, one of which is fixedly connected to the base plate and the other is hinged to the base plate. An upper roller and two lower rollers are rotatably arranged between the two supports. The upper roller is located above the two lower rollers and the two lower rollers are arranged side by side.

[0007] Two feeding mechanisms are distributed on both sides of the two lower rollers. Each feeding mechanism includes several telescopic components fixedly mounted on a base plate, a support component connected to the telescopic ends of the telescopic components, a sliding component slidably mounted on the support component along the axial direction of the upper roller, and a driving component mounted on one side of the support component. The power output end of the driving component is connected to the sliding component.

[0008] Two limiting mechanisms are respectively arranged on the sliding parts of the two feeding mechanisms. Each limiting mechanism includes two limiting parts that slide in opposite directions on the corresponding sliding parts. Each limiting part slides along the axial direction of the upper roller and is provided with a locking part between it and the corresponding sliding part.

[0009] Compared with existing technologies, this invention has the following advantages: During use, in the process of bending and rolling the sheet material, the two limiting members are slidably operated, ensuring that the distance between the two limiting members is the same as the width of the sheet material. The two limiting members prevent the sheet material from shifting during the rolling process, thus guaranteeing the quality of the finished product. Furthermore, during the rolling process, the telescopic members can be used to adjust the support members and sliding members to move closer to or further away from the upper and lower rollers, ensuring that the sheet material remains between the two limiting members. After the sheet material is rolled, the bracket hinged to the support plate is rotated open, and then several telescopic members are activated to push the support members towards the rolled sheet material. The sliding members on the two support members lift the sheet material, and then the telescopic members are closed, and the two driving members are activated to send the sheet material out between the upper and lower rollers. The operation is simple and convenient, effectively limiting the sheet material during the rolling process to ensure the quality of the finished product. It also allows for quick unwinding of the sheet material, saving time and effort, and protecting the upper and lower rollers from collisions with the rolled sheet material.

[0010] Preferably, the sliding member includes a sliding plate that is slidably mounted on the support member along the axial direction of the upper roller. The sliding plate has an installation groove along its length on the side wall facing the upper roller. Several rotating rollers are rotatably mounted side by side in the installation groove along its opening direction. Two limiting members are slidably connected to the installation groove. The locking member is disposed between the limiting members and the sliding plate. A slider is fixedly mounted on the side wall of the sliding plate away from the upper roller. The slider is connected to the power output end of the driving member.

[0011] Preferably, the support member includes a support plate fixedly connected to the telescopic ends of a plurality of telescopic members. The support plate is arranged at an angle and has a groove along its length. The slider is slidably connected to the groove, and the power output end of the drive member passes through the groove and is connected to the slider.

[0012] Preferably, the driving component includes a motor fixedly mounted on one side of the support plate and a screw rotatably mounted therein along the length of the slide groove. One end of the screw freely extends out of the slide groove and is coaxially and fixedly connected to the power output shaft of the motor. The slider has a threaded hole, through which the screw freely passes and is threadedly connected.

[0013] Preferably, each of the telescopic components includes an inclined hydraulic cylinder, the connecting end of which is fixedly connected to the base plate, and the telescopic end of which is fixedly connected to the support plate.

[0014] Preferably, each of the limiting members includes a limiting plate that is slidably connected to the mounting groove. The limiting plate is arranged perpendicular to the opening direction of the mounting groove and is located above a plurality of rotating rollers. The locking member is disposed between the limiting plate and the support plate.

[0015] Preferably, there are two locking members located on both sides of the limiting plate, and each locking member includes a connecting block fixedly connected to the limiting plate and a locking bolt threaded through the connecting block.

[0016] Preferably, the mounting groove is stepped, the width of the groove opening is smaller than the width of its bottom, and L-shaped plates are fixedly installed at both ends of the limiting plate. The vertical section of the L-shaped plate is connected to the limiting plate, and the horizontal section of the L-shaped plate extends into the mounting groove and slides and engages with its inner wall.

[0017] Preferably, a hydraulic station is fixedly installed on the base plate, and the hydraulic station is used to provide power to each hydraulic cylinder.

[0018] Preferably, there are three hydraulic cylinders located on the same side of the lower roller.

[0026] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] like Figure 1-5As shown, an embodiment of the present invention provides an upper roller universal plate rolling machine, comprising: a base plate 1, on which two supports 2 are arranged facing each other, one support 2 being fixedly connected to the base plate 1 and the other support 2 being hinged to the base plate 1; an upper roller 4 and two lower rollers 3 are rotatably arranged between the two supports 2, the upper roller 4 being located above the two lower rollers 3, and the two lower rollers 3 being arranged side by side; two feeding mechanisms distributed on both sides of the two lower rollers 3, each feeding mechanism including a plurality of telescopic members fixedly installed on the base plate 1, a support member connected to the telescopic ends of the plurality of telescopic members, a sliding member slidably arranged on the support member along the axial direction of the upper roller 4, and a driving member arranged on one side of the support member, the power output end of the driving member being connected to the sliding member; and two limiting mechanisms correspondingly arranged on the sliding members of the two feeding mechanisms, each limiting mechanism including two limiting members slidably arranged facing each other on the corresponding sliding member, each limiting member sliding along the axial direction of the upper roller 4 and having a locking member between it and the corresponding sliding member.

[0028] During the bending and rolling process, the two limiting components are slidably operated to ensure that the distance between the two limiting components is the same as the width of the sheet. The two limiting components prevent the sheet from shifting during the rolling process, thus ensuring the quality of the finished product. Furthermore, during the rolling process, the telescopic components can be used to adjust the support and sliding components to move closer to or further away from the sheet between the upper roller 4 and the lower roller 3, ensuring that the sheet remains between the two limiting components at all times. After the sheet is rolled, the bracket 2, which is hinged to the support plate 6, is rotated to open. Then, several telescopic components are activated to push the support components towards the rolled sheet. The sliding components on the two support components lift the sheet. After the telescopic components are closed, the two driving components are activated to send the sheet out between the upper roller 4 and the lower roller 3. The operation is simple and convenient. It can limit the sheet during the rolling process to ensure the quality of the finished product, and it can also quickly unroll the sheet, saving time and effort. At the same time, it can also protect the upper roller 4 and the lower roller 3 from colliding with the rolled sheet.

[0029] Other structures and their operating principles included in the universal rolling mill used in this invention are disclosed in Chinese Utility Model Patent No. CN2270571Y, and therefore will not be described in detail here.

[0030] like Figure 1-5As shown in another embodiment of the present invention, the universal upper roller plate rolling machine further optimizes its sliding component, support component, driving component, and telescopic component. The sliding component includes a sliding plate 7 slidably mounted on the support component along the axial direction of the upper roller 4. The sliding plate 7 has an installation groove 71 opened along its length direction on the side wall facing the upper roller 4. A plurality of rotating rollers 72 are rotatably mounted side by side in the installation groove 71 along its opening direction. Two limiting components are slidably connected to the installation groove 71. The locking component is disposed between the limiting component and the sliding plate 7. A slider 73 is fixedly mounted on the side wall of the sliding plate 7 away from the upper roller 4. The slider 73 is connected to the power output end of the driving component. When the plate is located between the two limiting components, it will contact the plurality of rotating rollers 72. During the plate rolling process, the plurality of rotating rollers 72 will assist the plate movement. With the joint cooperation of the two limiting components and the plurality of rotating rollers 72, the plate can be rolled stably and quickly.

[0031] Preferably, the mounting groove 71 is stepped, and the width of the groove opening is smaller than the width of its bottom. L-shaped plates 83 are fixedly installed at the bottom of both ends of the limiting plate 8. The vertical section of the L-shaped plate 83 is connected to the limiting plate 8, and the horizontal section of the L-shaped plate 83 extends into the mounting groove 71 and slides and engages with its inner wall. This allows the limiting plate 8 to slide stably along the mounting groove 71 with the cooperation of the horizontal section of the L-shaped plate 83 and the limiting component, without interfering with the rotating rollers 72.

[0032] The support member includes a support plate 6 that is fixedly connected to the telescopic ends of several telescopic members. The support plate 6 is arranged at an angle and has a groove 61 along its length. The slider 73 is slidably connected to the groove 61. The power output end of the drive member passes through the groove 61 and is connected to the slider 73.

[0033] The driving component includes a motor 62 fixedly installed on one side of the support plate 6 and a screw 63 rotatably installed in the slide groove 61 along its length. One end of the screw 63 freely passes through the slide groove 61 and is coaxially and fixedly connected to the power output shaft of the motor 62. The slider 73 has a threaded hole 74, through which the screw 63 freely passes and is threadedly connected.

[0034] Each of the aforementioned telescopic components includes an inclined hydraulic cylinder 5, the connecting end of which is fixedly connected to the base plate 1, and the telescopic end of which is fixedly connected to the support plate 6. Preferably, a support rod 51 is also fixedly connected between the side of each hydraulic cylinder 5 closest to the base plate 1 and the base plate 1 to provide auxiliary support for the hydraulic cylinder 5. At the same time, there are three hydraulic cylinders 5 located on the same side as the lower roller 3, which reduces equipment costs while ensuring stable support.

[0035] like Figure 1-4As shown, according to another embodiment of the present invention, the universal plate rolling machine with upper roller further optimizes the limiting members and locking members included therein. Each limiting member includes a limiting plate 8 slidably connected to the mounting groove 71. The limiting plate 8 is arranged perpendicular to the opening direction of the mounting groove 71 and is located above a plurality of rotating rollers 72. The locking member is disposed between the limiting plate 8 and the support plate 6. There are two locking members located on both sides of the limiting plate 8. Each locking member includes a connecting block 81 fixedly connected to the limiting plate 8 and a locking bolt 82 threaded through the connecting block 81.

[0036] During operation, slide the two limiting plates 8 according to the width of the plate to adjust the distance between the two limiting plates 8. After adjustment, tighten all the locking bolts 82 so that they abut against the sliding plate 7 to fix each limiting plate 8.

[0037] like Figure 1 As shown, according to another embodiment of the present invention, the universal plate rolling machine with upper roller is preferably provided with a hydraulic station 9 fixedly installed on the base plate 1, the hydraulic station 9 being used to provide power to each hydraulic cylinder 5.

[0038] The working principle of this invention is as follows: When using this invention, the two limiting plates 8 are slidable in the mounting groove 71 according to the width of the sheet material to adjust the distance between the two limiting plates 8 so that the sheet material can pass through the two limiting plates 8. During the winding process of the sheet material, the hydraulic cylinders 5 on both sides of the lower roller 3 are continuously activated to adjust the distance between the support plates 6 and sliding plates 7 on both sides of the lower roller 3 and the sheet material, so that the sheet material can always be located between the two limiting plates 8 on each side of the lower roller 3. At the same time, the sheet material will also contact the rotating roller 72, which assists in winding. After winding is completed, the bracket 2 hinged to the base plate 1 is opened by rotating the flipping cylinder. Then, the hydraulic cylinders 5 on both sides of the lower roller 3 are activated so that the sliding plates 7 abut against the sheet material. The two sliding plates 7 lift the sheet material. Then, the hydraulic cylinders 5 are closed and the motor 62 is started to drive the screw 63 to rotate, so that the slider 73 moves along the direction of the screw 63, which drives the sliding plates 7 to move the wound sheet material out between the upper roller 4 and the lower roller 3.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
