Description

Technical Field

[0001] This utility model relates to the field of leveling technology, and in particular to a metal plate leveling device. Background Technology

[0002] Explosive welding is a welding method that utilizes the high-pressure shock wave generated during explosive detonation to drive the metal movement, causing them to collide and form a jet that removes the surface film, ultimately creating a metallurgical bond under the high pressure of the shock wave. Explosive welding uses explosives as an energy source to weld metals together. This welding method leverages the shock wave from an explosive detonation to subject the metals to high-speed impact, bonding them together in a very brief metallurgical process.

[0003] Existing metal sheets are prone to explosive deformation after explosive welding and need to be leveled by equipment. Currently, hydraulic presses are used for local treatment, but the movement and rotation of the sheets during the leveling process need to be completed by overhead cranes, which is cumbersome, inefficient, and poses certain safety hazards. Utility Model Content

Therefore, one objective of this invention is to provide a metal plate leveling device that can complete the translation, rotation, and positioning of plates without relying on overhead cranes, significantly shortening the plate adjustment time.

[0005] The metal plate leveling device proposed in this utility model includes a hydraulic press, a worktable fixed inside the hydraulic press, a working groove below the worktable on the hydraulic press, a movable plate slidably connected inside the working groove, several studs fixed in a circular array on the top of the movable plate, a sleeve fitted on the outer surface of the studs, and ball bearings rolled inside the sleeve, a lifting assembly for adjusting the height of the movable plate fixed on the inner wall of the working groove, and a guide hole for cooperating with the sleeve through the top of the worktable.

[0006] Preferably, the lifting assembly includes a connecting seat, a lead screw is rotatably connected to the inner center of the connecting seat, movable rods are sleeved on the outer surfaces of the left and right ends of the lead screw, rotating seats are fixed at the four bottom corners of the movable plate, a connecting rod is rotatably connected between the rotating seats and the movable rods, a motor is fixed at one end of the connecting seat, and the rotating end of the motor is fixed to the lead screw.

[0007] Preferably, the hydraulic press is equipped with a hydraulic cylinder for leveling the sheet metal.

[0008] Preferably, guide rods through the movable rod are fixed at both ends of the connecting seat.

[0009] Preferably, a controller is fixed to one side of the hydraulic press.

[0010] Preferably, the hydraulic press has fixed bases at all four corners of its bottom.

[0011] Preferably, the threads on both sides of the lead screw rotate in opposite directions.

[0012] The beneficial effects of this utility model are: by linking the lead screw and moving rod lifting assembly and the ball bearing support structure, the moving plate can be quickly lifted and the metal plate can be raised. The translation, rotation and positioning operations of the plate can be completed without relying on the crane hoisting, which significantly shortens the plate adjustment time.

[0019] Reference Figure 1-5The metal plate leveling device includes a hydraulic press 1, with a worktable 2 fixed inside the hydraulic press 1, providing a stable working surface for the entire leveling operation. A working groove 3 is located below the worktable 2 on the hydraulic press 1. A movable plate 4 is slidably connected inside the working groove 3. Several studs 5 are fixed in a circular array on the top of the movable plate 4. This arrangement ensures more uniform and stable support for the plate. A sleeve 6 is fitted onto the outer surface of the studs 5, and ball bearings 7 are rolled inside the sleeve 6. The ball bearings 7 contact the metal plate, reducing movement resistance through rolling friction. A lifting assembly for adjusting the height of the movable plate 4 is fixed to the inner wall of the working groove 3. A guide hole 18, which mates with the sleeve 6, is opened through the top of the worktable 2. The guide hole 18 guides the movement of the sleeve 6, ensuring that the sleeve 6 moves stably in the vertical direction during lifting and lowering, thus improving the accuracy and reliability of the leveling.

[0020] The lifting assembly includes a connecting seat 8, with a lead screw 9 rotatably connected to its internal center. Moving rods 10 are fitted onto the outer surfaces of both ends of the lead screw 9. Rotating seats 12 are fixed at each of the four bottom corners of the moving plate 4. Connecting rods 11 are rotatably connected between the rotating seats 12 and the moving rods 10. A motor 13 is fixed to one end of the connecting seat 8, and the rotating end of the motor 13 is fixed to the lead screw 9. The rotational movement of the lead screw 9 is transmitted through the moving rods 10 and connecting rods 11, transforming it into a smooth lifting and lowering movement of the moving plate 4, thus achieving precise height control of the moving plate 4. The motor 13 provides a stable and reliable power source for the rotation of the lead screw 9. By controlling the forward and reverse rotation of the motor 13, the raising or lowering operation of the moving plate 4 can be easily achieved. Simultaneously, the metal plate is lifted and lowered via the ball bearings 7. The metal plate can be rotated arbitrarily during operation, making it convenient to use.

[0021] The hydraulic press 1 is equipped with a hydraulic cylinder 14 for leveling the sheet metal. Through the reciprocating motion of the hydraulic cylinder 14, the sheet metal is repeatedly squeezed and leveled, effectively eliminating various deformations caused by the explosive welding, restoring the flatness of the sheet metal, and ensuring that it meets the precision requirements of subsequent processing and use.

[0022] Both ends of the connecting seat 8 are fixed with guide rods 15 that pass through the moving rod 10. The setting of the guide rods 15 further enhances the stability of the moving rod 10 during the movement process, prevents the moving rod 10 from shaking or deviating under the drive of the lead screw 9, and ensures that the entire lifting assembly can stably and accurately drive the moving plate 4 to move up and down.

[0023] A controller 16 is fixed on one side of the hydraulic press 1. The controller 16 serves as the control center of the entire leveling device and can precisely control and coordinate key actuators such as the motor 13 and the hydraulic cylinder 14.

[0024] The bottom of the hydraulic press 1 is fixed with four corner brackets 17, which can firmly fix the entire leveling device to the ground or work platform, ensuring that there will be no displacement or shaking during the operation of the equipment, providing a solid and stable foundation for the leveling operation, and ensuring the safety of the equipment and operators.

[0025] The threads on both sides of the lead screw 9 rotate in opposite directions. This design allows the moving rods 10 at the left and right ends to move in opposite directions when the lead screw 9 rotates, thereby driving other connected components to achieve coordinated movement.

[0026] When using this device, the metal plate to be leveled is first placed on the worktable 2. When it is necessary to move and rotate the metal plate, simply start the motor 13 to drive the lead screw 9 to rotate. The rotation of the lead screw 9 can be transmitted through the moving rod 10 and the connecting rod 11 to the smooth lifting and lowering motion of the moving plate 4. The rising of the moving plate 4 drives the ball bearings 7 to move, and the ball bearings 7 lift the metal plate. At this time, the metal plate can be moved or rotated at will so that the position to be leveled is aligned with the hydraulic cylinder 14. Then, the motor 13 reverses, causing the ball bearings 7 to drive the metal plate down and make the bottom of the metal plate contact the worktable 2. At the same time, the ball bearings 7 move away from the metal plate. At this time, the hydraulic cylinder 14 is used to level the metal plate.
