Description

Technical Field

[0001] The invention relates to the technical field of leveling machine equipment, in particular to a gap adjusting device for a heavy-duty plate leveling machine. Background Art

[0002] The plate leveler is a device specially used to straighten metal plates. It uses mechanical force to correct bent and deformed metal plates to achieve the ideal flatness and geometric shape. The working principle of the leveler is based on the elastic-plastic deformation characteristics of the material. It uses mechanical force to make the metal plate plastically deform, thereby eliminating internal stress and improving flatness.

[0003] Leveling machines have been widely used in industry. They are characterized by advanced technology, high leveling accuracy, wide process range, high degree of automation, and good working reliability under high strength. The application scope involves aviation, shipbuilding, metallurgy, instrumentation, stainless steel products, etc., and they play an important role in the verticality, parallelism and appearance of industrial structural parts. When the existing plate leveling machines are leveling plates of different sizes and thicknesses, it is necessary to adjust the spacing of each set of upper and lower rollers one by one, and the adjustment method is mostly to remove the bolts, adjust the spacing, and then fix it with bolts. This step is relatively cumbersome. The spacing control between each set of roller groups requires additional measurement tools to assist in adjustment, otherwise it is easy to cause deviations in the adjusted spacing, further increasing the workload of adjustment.

[0004] This adjustment method is not only time-consuming and labor-intensive, but also difficult to ensure accuracy, because manual adjustment is difficult to achieve high-precision requirements and is easily affected by the operator's skill level. In addition, frequent removal and installation of bolts also increases the maintenance cost and failure risk of the equipment.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original leveling machine. Summary of the invention

[0010] Preferably, the empty groove is configured as a comb-shaped structure, and the empty groove, the liquid channel and the storage groove are filled with hydraulic oil.

[0011] Preferably, the locking portion includes a gear rod, a gear block plate, a groove, a return spring, a movable groove, a lever, a fulcrum, a trigger block, and a pressure spring. A gear rod is connected to the top of each second piston block, and a gear block plate is snap-connected to each side of the gear rod. The gear block plate is located in the groove, and a return spring is connected between each gear block plate and the groove. Each end of the gear block plate passes through the groove and is located in the movable groove, and the movable groove is opened on both sides of the support frame. A lever is provided in each movable groove, and each lever is rotatably connected to a fulcrum, and the fulcrum is connected to both sides of the inner wall of the corresponding movable groove.

[0014] Compared with the prior art, the invention has the following beneficial effects: the gap adjustment device for the heavy-duty plate leveling machine realizes efficient leveling of the plate through the coordinated operation of the transmission mechanism and the auxiliary rollers. The core of the device lies in its spacing adjustment structure, which can quickly and accurately adjust the spacing between multiple auxiliary rollers and the transmission mechanism synchronously according to the thickness requirements of different plates. This process benefits from the application of hydraulic control technology, combined with the labor-saving structural design of the lever principle, which not only ensures the adjustment accuracy, but also greatly reduces the operation time and labor intensity.

[0015] In actual operation, the operator only needs to input the thickness parameters of the plate through a simple control panel, and the electric telescopic rod will extend to a certain length, and cooperate with the piston block and liquid channel and other structures to achieve fine adjustment of the auxiliary roller spacing. This intelligent adjustment method not only improves the efficiency of the leveling operation, but also reduces the risk of plate damage caused by improper manual adjustment. In addition, the design of the lever labor-saving structure makes it easy to adjust the distance between the rollers even when handling heavy plates, greatly improving the flexibility and safety of the operation.

[0030] Working principle: According to Figure 1 As shown, the plate can be leveled by the cooperation of the conveying mechanism 2 and the auxiliary roller 5. According to the size and thickness of the plate, the parameters of the plate are input into the PLC control panel. The PLC control panel controls the electric telescopic rod 303 to extend upward by a certain distance, so that the push plate 302 moves upward in the empty groove 301, so that the first piston block 304 thereon pushes the hydraulic oil into the liquid channel 305 and then into the storage groove 306. The hydraulic oil flows in the liquid channel 305 and contacts the inclined surface of the trigger block 315, squeezing the trigger block 315 into the movable groove 312. The lever 313 moves and rotates along the fulcrum 314. At the same time, the pressure spring 316 is compressed, and the other end of the lever 313 drives the tooth block plate 309 to move into the groove 310, disengaging from the engagement with the tooth rod 308, thereby stopping the locking and limiting effect of the tooth rod 308. As the hydraulic oil enters the storage groove 306, it pushes the second piston block 307 and the tooth rod 308 to move upward, driving the bracket 4 and the auxiliary roller 5 to move upward, thereby adjusting the distance between the conveying mechanism 2 and the auxiliary roller 5. This is the working principle of the gap adjustment device of the heavy-duty plate leveling machine.
