Abstract
Description
Technical Field
[0001] This utility model specifically relates to a plate rolling machine that can prevent ship parts from shifting. Background Technology
[0002] A plate rolling machine is a device that uses work rollers to bend and shape sheet metal. It can form parts of different shapes such as cylindrical and conical parts, and is a very important processing equipment. Its working principle is that the work rollers are moved by external forces such as hydraulic pressure and mechanical force, thereby bending or rolling the sheet metal into shape. Depending on the rotation and position changes of the work rollers of different shapes, elliptical, arc-shaped, cylindrical and other parts can be processed. At present, some cylindrical ship parts need to be produced using plate rolling machines.
[0003] However, when traditional plate rolling machines are used to produce cylindrical ship parts, the plates are prone to shifting during the rolling process, which affects the rolling accuracy and causes the rolled parts to fail to meet the usage requirements, thus requiring improvement.
[0004] Therefore, it is necessary to invent a plate rolling machine that can prevent ship parts from shifting to solve the above problems. Utility Model Content

By setting two first clamping plates that can approach each other, and two second clamping plates and limiting plates that can approach each other synchronously under the drive of the first clamping plates, the left and right sides of the plate can be fitted and limited when the plate is conveyed into the gap between the upper and lower rollers. This avoids the plate from shifting to the left or right when bending without affecting the conveying of the plate.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a plate rolling machine that can prevent ship parts from shifting, including a workbench and a plate rolling machine body located on top of the workbench;
[0009] The plate rolling machine body includes a frame installed on the left and right sides of the top of the workbench, two lower rollers installed between the two frames and arranged in a front-to-back row, and an upper roller located above the two lower rollers and connected to the two frames at both ends respectively.
[0010] Both of the two frames are connected to the front side with strip plates, and a positioning mechanism is provided between the two strip plates. The positioning mechanism includes two horizontal plates installed between the two strip plates and arranged side by side, two first clamping plates disposed between the two horizontal plates and capable of moving closer to or further away from each other along the length direction of the horizontal plates, and a second clamping plate located behind the two first clamping plates and capable of moving along the length direction of the strip plates.
[0011] The positioning mechanism further includes cover plates respectively installed on the top of the two first clamping plates, vertical rods respectively passing through the two cover plates and movable along the height direction of the first clamping plates, and pressure plates connected to the bottom of each vertical rod.
[0012] Preferably, a drive motor is mounted on the outer side of one of the strip plates, a rotating shaft is mounted on the output end of the drive motor, and the end of the rotating shaft away from the drive motor extends into the interior of the other strip plate.
[0013] Preferably, the middle part of the rotating shaft is configured as a screw, the outer thread of the screw is configured as two segments, and the two segments of threads are configured with opposite directions. Movable plates are sleeved on both the left and right sides of the screw, and the bottom of the two first clamping plates are respectively connected to the top of the two movable plates.
[0014] Preferably, a limiting plate is installed on the side wall of each of the two first clamping plates near the second clamping plate, and a cylinder is installed on the top of each of the two limiting plates. The output ends of the two cylinders are respectively connected to the top of the second clamping plate through a connecting plate.
[0015] Preferably, each of the two second clamping plates is connected to a plug rod on the side closest to the first clamping plate, and the ends of the two plug rods away from the second clamping plates are inserted into the corresponding limiting plates.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0032] This utility model provides, for example Figure 1-6 The plate rolling machine shown includes a workbench 1 and a plate rolling machine body 2 located on top of the workbench 1.
[0033] The plate rolling machine body 2 includes a frame 3 installed on the left and right sides of the top of the workbench 1, two lower rollers 4 installed between the two frames 3 and arranged in a front-to-back row, and an upper roller 5 located above the two lower rollers 4 and connected to the two frames 3 at both ends respectively.
[0034] Both of the two frames 3 are connected to the front side of a strip plate 6. A positioning mechanism is provided between the two strip plates 6. The positioning mechanism includes two horizontal plates 71 installed between the two strip plates 6 and arranged side by side, two first clamping plates 72 disposed between the two horizontal plates 71 and able to move closer to or further away from each other along the length direction of the horizontal plates 71, and a second clamping plate 73 located behind the two first clamping plates 72 and able to move along the length direction of the strip plate 6.
[0035] The positioning mechanism further includes cover plates 74 respectively installed on the top of the two first clamping plates 72, vertical rods 75 respectively passing through the two cover plates 74 and movable along the height direction of the first clamping plates 72, and pressure plates 76 connected to the bottom of each vertical rod 75.
[0036] In one embodiment, a drive motor 8 is installed on the outer side of one of the strip plates 6. A rotating shaft is installed at the output end of the drive motor 8. The end of the rotating shaft away from the drive motor 8 extends into the interior of the other strip plate 6. A screw 9 is set in the middle of the rotating shaft. The outer thread of the screw 9 is set in two segments with opposite directions. Movable plates 10 are sleeved on both sides of the screw 9. The bottoms of the two first clamping plates 72 are respectively connected to the tops of the two movable plates 10. When the output end of the drive motor 8 rotates, the two movable plates 10 can drive the two first clamping plates 72 to move closer or further apart through the threads with different directions, thereby achieving the fitting and positioning or release of the plate and ensuring the accuracy of the plate when bending it into cylindrical ship fittings.
[0037] In one embodiment, a limiting plate 11 is installed on the side wall of each of the two first clamping plates 72 near the second clamping plate 73. A cylinder 12 is installed on the top of each of the two limiting plates 11. The output ends of the two cylinders 12 are connected to the top of the second clamping plate 73 through connecting plates. A rod 13 is connected to the side of each of the two second clamping plates 73 near the first clamping plate 72. The end of each rod 13 away from the second clamping plate 73 is inserted into the corresponding limiting plate 11. The limiting plate 11 has a slot for inserting the rod 13. When the output end of the cylinder 12 extends or retracts, the crossbar will move along the inner wall of the slot, which can greatly improve the stability of the second clamping plate 73 when moving back and forth. The limiting plate 11 and the left and right side walls of the second clamping plate 73 are aligned. The limiting plate 11 can work together with the first clamping plate 72 and the second clamping plate 73 to fit the left and right side walls of the plate, further ensuring that the plate will not shift when bending.
[0038] In one embodiment, a plurality of parallel long rods 16 are installed between the two strip plates 6. Each long rod 16 is fitted with a rotating rod 17 on its outer side. When the plate moves on the top of the long rod 16, the rotating rod 17 can rotate around the axis of the long rod 16, so that the plate can move smoothly and steadily between the upper roller 5 and the lower roller 4 during conveying, thereby completing the plate rolling process.
[0039] In one embodiment, springs 14 are sleeved on the outer sides of both vertical rods 75, and the springs 14 are located between the pressure plate 76 and the cover plate 74. Baffles 15 are installed at the top of both vertical rods 75, and the baffles 15 are located above the cover plate 74. The springs 14 are used to apply a downward elastic force to the pressure plate 76 so that it can press against the top of the plate, while the baffles 15 prevent the pressure plate 76 from being too low and limit the vertical rods 75 so that they can be stably placed in the cover plate 74.
[0040] In one embodiment, both pressure plates 76 are provided with inclined sections at their bottoms, and the inclined sections are provided on the bottom of the adjacent side of the two pressure plates 76. This allows the pressure plates 76 to decompose the reaction force applied to the side of the plate into an upward thrust when they move with the moving plate 10. This allows the pressure plates 76 to drive the vertical rod 75 to move upward, and under the action of the spring force 14, press downward against the top of the plate, preventing the plate from suddenly curling up when it is rolled.
[0041] The specific implementation method is as follows: When using this utility model, the operator adjusts the plate rolling machine body 2 according to the thickness of the plate so that the distance between the two lower rollers 4 and the upper roller 5 is adapted. Then, the plate rolling machine body 2 is started so that the lower rollers 4 and the upper roller rotate, pushing the plate into the gap between the upper roller 5 and the lower roller, thus realizing plate rolling. This is the prior art of the plate rolling machine body 2, and for the sake of space, it will not be described in detail here.
[0042] During the plate rolling process, the plate first moves along the top of the horizontal plate 71 toward the gap between the upper roller 5 and the lower roller. At this time, the operator can start the drive motor 8 to make its output end rotate in the forward direction, which in turn makes the screw 9 rotate in the forward direction. Since the threads on the outer sides of its left and right ends rotate in opposite directions, the two moving plates 10 will move closer to each other along the length of the horizontal plate 71, so that the two first clamping plates 72 move closer to each other and fit against the left and right sides of the plate to position the plate and prevent any deviation in the left and right directions during the rolling process. This effectively prevents the plate from deviating when bending.
[0043] Furthermore, when the two first clamping plates 72 approach each other, the two second clamping plates 73 will also approach each other as the first clamping plates 72 move horizontally, assisting the first clamping plates 72 in making a large-scale fit with the left and right side walls of the plate. At the same time, the operator can adjust the distance between the two second clamping plates 73 and the lower roller by controlling the extension of the output end of the cylinder 12, so that the second clamping plates 73 can fit the plate without affecting the subsequent removal of the formed cylindrical ship parts. That is, after the plate is formed, the operator can control the retraction of the output end of the cylinder 12 to move the two second clamping plates 73 away from the lower roller 4, making way for the formed cylindrical ship parts, so that they can move horizontally to the left along the outside of the upper roller 5 until they are removed.
[0044] Furthermore, when the two first clamping plates 72 approach each other, the two pressure plates 76 also approach each other. At this time, the left and right sides of the plate will contact the inclined section. As the two pressure plates 76 approach each other, the plate will force the pressure plates 76 to move upward. At this time, the spring 14 contracts and shortens, and applies a downward elastic force to the pressure plate 76, so that it can always be in contact with the top of the plate and apply pressure to the top of the plate, thereby avoiding the safety hazard caused by the tail end of the plate bending significantly.
[0045] After the sheet metal is formed, the workers open the pressure roller rod on the right side of the plate rolling machine body 2, and turn the support plate on the right side that supports the upper roller 5 downwards. The formed cylindrical ship parts can then be taken out along the length of the upper roller 5 to the right. The support plate is then reset, and the output end of the drive motor 8 is rotated in the opposite direction to reset the positioning mechanism. The parts can then be put into subsequent use until the mass production of cylindrical ship parts is completed.
[0046] This embodiment specifically addresses the problem in the prior art where, when using traditional plate rolling machines to produce cylindrical ship fittings, the plate material is prone to shifting during the rolling process, affecting the rolling accuracy and resulting in the rolled fittings not meeting usage requirements, necessitating improvement.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
