Description

Technical Field

[0001] This utility model relates to the field of three-roll plate bending machine technology, and in particular to a horizontally adjustable three-roll plate bending machine. Background Technology

[0002] The horizontally adjustable three-roll plate bending machine is an advanced sheet metal bending and forming equipment widely used in machinery manufacturing, boilers, bridges, and many other industries. The upper roller of the horizontally adjustable three-roll plate bending machine achieves sheet metal bending through a hydraulically raised pressure head. The two side pressure rollers can move independently horizontally to adapt to different shape requirements. By adjusting the position of the side pressure rollers and the pressure of the lower pressure rollers, bending and rolling operations can be performed on the sheet metal. The sheet metal is fed horizontally, ensuring that the feeding end always remains horizontal. The tight fit between the rollers makes rounding possible. The equipment is simple to operate and requires relatively low operator skill. It consists of an upper roller and two lower rollers. The upper roller is the driven roller and can move up and down, while the two lower rollers are the driving rollers, driven by a motor to rotate and bend and roll the sheet metal. The two lower rollers can move horizontally. By adjusting the distance and relative position between the lower rollers, the bending radius and shape of the sheet metal can be changed, enabling the rolling of workpieces of different specifications and shapes. The horizontally adjustable three-roll plate bending machine adopts advanced design and manufacturing processes and has high working efficiency. The equipment can quickly complete the bending and rolling of sheet metal, reducing processing time and costs. Equipped with a high-precision control system and measuring devices, it can achieve accurate rolling and rounding. The rolling accuracy can reach a high level, meeting the precision requirements of various industries.

[0003] In the prior art, when bending a sheet metal, the sheet metal is placed into a three-roll plate bending machine for bending. After bending, one side panel of the three-roll plate bending machine is rotated so that one end of the top roller is exposed. The sheet metal is then taken out from the side, and the three rollers are resealed by rotating the side panel. The bending process of the sheet metal continues.

[0004] However, when the sheet is removed from the three-roll plate rolling machine, the top roller will only be supported by one end for a period of time. After long-term use, the top roller may become unstable, which may affect the rolling accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a horizontally adjustable three-roll plate bending machine, which solves the problem in the prior art that the uppermost roller can only rely on one end for support for a period of time when the plate is being cut, which easily leads to the uppermost roller being unstable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The horizontally adjustable three-roll plate bending machine includes a base and two side plates. The surface of the side plates is equipped with two side pressure rollers via a drive device. Each side plate has a pressure device on its top. One pressure device is fixedly connected to the side plate, and the other pressure device is rotatably connected to the side plate. A lower pressure roller is located between the two pressure devices. The top of the base has two adjustment slots, and two adjustment blocks are slidably connected inside the adjustment slots. The top of the adjustment blocks is equipped with a support rod via an adjustment mechanism. An arc-shaped bearing block is fixedly connected between the two support rods. The bearing block is located below the lower pressure roller. A synchronization mechanism is provided between the two support rods on the same side.

[0008] Preferably, the adjustment mechanism includes a screw sleeve rotatably connected to the top of the adjustment block, and the screw sleeve is threadedly connected to the surface of the support rod.

[0009] Preferably, two rotating rods are fixedly connected to the surface of the screw sleeve, and an anti-moving rod is provided on the top of the rotating rod. Several anti-moving grooves are provided on the top of the adjusting block in a circular pattern, and the anti-moving rods are located inside the adjacent anti-moving grooves.

[0010] Preferably, the synchronization mechanism includes a synchronization rod passing between two support rods, the surface of the synchronization rod having a plurality of synchronization grooves, the surface of the support rod having a receiving groove, and a U-shaped synchronization block being slidably connected inside the receiving groove, with both ends of the synchronization block located inside adjacent synchronization grooves.

[0011] Preferably, a lubricating wheel is rotatably connected to the inner side of the bearing block.

[0012] Preferably, the interior of the adjustment groove is T-shaped, and two rollers located inside the adjustment groove are rotatably connected to both sides of the adjustment block.

[0013] This utility model has the following beneficial effects:

[0014] When cutting the sheet material, a pressure device is rotated. During this process, two bearing blocks alternately support the lower pressure roller, protecting it and preventing it from tilting or becoming unstable, thus ensuring the accuracy of the lower pressure roller when rolling the sheet.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A horizontally adjustable three-roll plate rolling machine includes a base 1 and two side plates 2. Two side pressure rollers 3 are mounted on the surface of the side plates 2 via a drive mechanism. Each side plate 2 has a pressure device on its top; one pressure device is fixedly connected to the side plate 2, and the other is rotatably connected. A lower pressure roller 4 is located between the two pressure devices. In existing technology, when using a three-roll plate rolling machine, a metal plate is placed between the lower pressure roller 4 and the side pressure rollers 3, and then the drive and pressure devices are activated to roll up the metal plate. The equipment and methods used in this process are all existing mature technologies and can be directly used and operated using existing technology. After the metal plate is processed, one of the pressure devices is rotated to expose one end of the lower pressure roller 4, and then the metal plate is taken out from the side. Then, one of the pressure devices is reset to continue supporting the lower pressure roller 4. Two adjustment grooves 5 are opened on the top of the base 1. Two adjustment blocks 6 are slidably connected inside the adjustment grooves 5. Support rods 8 are mounted on the top of the adjustment blocks 6 via an adjustment mechanism 7. The two support rods 8 are fixedly connected... A fixed, arc-shaped support block 9 is connected. Before processing the metal sheet, the height of the support rod 8 needs to be adjusted by the adjustment mechanism 7 so that the support block 9 is adjusted to a suitable height. This height is the height of the lower pressure roller 4 after processing. It is necessary to ensure that the support block 9 and the surface of the lower pressure roller 4 are in close contact for support after processing. When the metal sheet is unloaded, the metal sheet leaves the side of the lower pressure roller 4. During this process, the metal sheet squeezes and drives one of the support blocks 9, causing the other support block 9 to move below the lower pressure roller 4. This allows the support block 9 to support the lower pressure roller 4. During the unloading process of the metal sheet, the support block 9 and the support rod 8 can also assist in supporting the lower pressure roller 4, so that the lower pressure roller 4 will not tilt or be damaged. The support block 9 is located below the lower pressure roller 4. A synchronization mechanism 10 is provided between the two support rods 8 on the same side. The synchronization mechanism 10 enables the two support blocks 9 to move synchronously, which is convenient for the metal sheet to drive the support block 9 to support the lower pressure roller 4 during unloading.

[0024] Furthermore, the adjustment mechanism 7 includes a screw sleeve 701 rotatably connected to the top of the adjustment block 6. The screw sleeve 701 is threadedly connected to the surface of the support rod 8. When it is necessary to adjust the height of the support rod 8 to adjust the height of the bearing block 9, the support rod 8 can be easily raised and lowered by rotating the screw sleeve 701, so that the height of the bearing block 9 also moves accordingly.

[0025] Furthermore, two rotating rods 702 are fixedly connected to the surface of the screw sleeve 701. An anti-movement rod 703 is inserted through the top of the rotating rod 702. Several anti-movement grooves 704 are circumferentially distributed on the top of the adjusting block 6. The anti-movement rods 703 are located inside the adjacent anti-movement grooves 704. When the screw sleeve 701 is rotated, the screw sleeve 701 can be rotated by applying force to the rotating rods 702. Before rotating the screw sleeve 701, the anti-movement rods 703 need to be lifted upward so that the anti-movement rods 703 can leave the anti-movement grooves 704, thereby allowing the screw sleeve 701 to rotate. After the screw sleeve 701 has finished rotating, the restriction on the anti-movement rods 703 is released, allowing the anti-movement rods 703 to fall into the anti-movement grooves 704 by gravity, preventing the screw sleeve 701 from rotating. This ensures the stability of the support rod 8 and the bearing block 9, and can stably support the lower pressure roller 4.

[0026] Furthermore, the synchronization mechanism 10 includes a synchronization rod 101 passing between two support rods 8. The surface of the synchronization rod 101 is provided with a plurality of synchronization grooves 102, and the surface of the support rod 8 is provided with a receiving groove 103. A U-shaped synchronization block 104 is slidably connected inside the receiving groove 103. Both ends of the synchronization block 104 are located inside the adjacent synchronization grooves 102. When bending the metal plate, the two bearing blocks 9 can be separated from each other according to the width of the metal plate, and then the synchronization rod 101 is inserted between the two support rods 8 on the same side. In this process, the synchronization block 104 inside the receiving groove 103 needs to be moved upward first, and then the synchronization rod 101 is inserted and the synchronization block 104 is released. The synchronization block 104 can enter the adjacent synchronization groove 102, thereby fixing the position of the synchronization rod 101. The movement of the support rod 8 can drive the other support rod 8 to move, thereby facilitating the synchronous movement of the two bearing blocks 9.

[0027] Furthermore, a lubricating wheel 11 is rotatably connected to the inner side of the bearing block 9. During the metal plate feeding process, while supporting the lower pressure roller 4, the bearing block 9 can also reduce the friction between itself and the lower pressure roller 4 through the lubricating wheel 11, which facilitates the movement of the bearing block 9.

[0028] Furthermore, the interior of the adjustment groove 5 is T-shaped, and two rollers 12 located inside the adjustment groove 5 are rotatably connected to both sides of the adjustment block 6. When the adjustment block 6 moves inside the adjustment groove 5, the rollers 12 can reduce the friction between the adjustment block 6 and the adjustment groove 5, and also prevent the adjustment block 6 from separating from the adjustment groove 5, thus ensuring the stable movement of the adjustment block 6.

[0029] In summary:

[0030] When rolling a metal sheet, the sheet is placed between the lower pressure roller 4 and two side pressure rollers 3. The drive and pressure devices on the side plate 2 are then activated to roll the sheet. After rolling, one of the pressure devices is rotated, exposing one end of the lower pressure roller 4, allowing the sheet to be removed from the side. During this process, the sheet presses against one of the support blocks 9, causing the support block 9 to move via the synchronizing rod 101, thus facilitating the support of the lower pressure roller 4 and ensuring its stability during sheet unloading. When processing metal sheets of different thicknesses and widths, the height of the support blocks 9 can be adjusted according to the sheet specifications. This requires first lifting the anti-movement rod 703 to disengage it from the anti-movement groove 704, then applying force to the threaded sleeve 701 via the rotating rod 702, causing the threaded sleeve 701 to move the support rod 8 up and down. After adjustment, the anti-movement rod 703 is released, allowing it to move freely. The device can enter the adjacent anti-movement groove 704. When the width of the metal plate changes, the synchronizing block 104 inside the receiving groove 103 can be lifted upwards first, so that the synchronizing block 104 is separated from the synchronizing groove 102. Then, the two support rods 8 can be moved away from or closer to each other. During this process, the synchronizing rod 101 will not be separated from the support rod 8. After the distance between the two support rods 8 is adjusted, the synchronizing block 104 can be lowered, so that the synchronizing block 104 re-enters the synchronizing groove 102, and the synchronizing rod 101 is fixed between the two support rods 8. The movement of the support rod 8 is achieved by the adjustment block 6 moving inside the adjustment groove 5 on the base 1. During the movement of the adjustment block 6, the friction can be reduced by the roller 12. When the bearing block 9 supports the lower pressure roller 4 and needs to move, the friction can be reduced by the lubricating wheel 11. With the above structure, when the metal plate is rolled, the lower pressure roller 4 can be easily supported during the metal plate unloading process, ensuring the stability of the lower pressure roller 4.
