Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines, in particular to a limiting mechanism for a leveling machine. Background Art

[0002] The leveling machine is mainly used to level various specifications of plates and cut plates. This machine is suitable for leveling various cold and hot rolled plates. Due to its convenient and simple operation, it is widely used in many industries such as machinery, metallurgy, building materials, chemicals, electronics, electricity, light industry, etc., especially in shipbuilding, locomotives, boilers and bridges, metal structure factories and other industries, and has become an indispensable product in production.

[0003] The patent specification with the announcement number CN218775422U discloses a leveling machine limit mechanism, including a U-shaped frame, a rotating roller, a pressure roller, a bearing seat, a strip rod, an adjusting screw and a driving motor, wherein two or more rotating rollers are installed inside the U-shaped frame, a strip rod is installed inside the U-shaped frame, and two or more bearing seats are installed at the bottom of the strip rod, and two or more pressure rollers are evenly installed inside the U-shaped frame, and the left and right ends of the pressure rollers are installed inside the bearing seat, and two adjusting screws are symmetrically installed at the top of the U-shaped frame, and a driving motor is installed at one end of the U-shaped frame, and one end of the driving motor is connected to one of the rotating rollers. The utility model can not only drive the two threaded blocks to move by rotating the bidirectional screw, and then drive the two U-shaped blocks to move closer to each other, but also drive the T-shaped magnetic block and the magnetic sheet to move by pulling the cylindrical rod, so as to facilitate the adjustment of the bidirectional screw and the moving block, and can also move the T-shaped magnetic block to adsorb and fit with the support block, so as to fix the position of the elliptical block.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed limit mechanism of a leveling machine has the following problems: in the prior art, a limit mechanism is only set at the position of the discharge port, but during the operation, the thickness of the plate is different. For materials of different thicknesses, sufficient limit cannot be performed during the leveling process, resulting in the inability to completely flatten the material. In view of this, a limit mechanism of a leveling machine is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a limiting mechanism for a leveling machine.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a leveling machine limiting mechanism, comprising a frame, an upper die is arranged on the upper part of the frame, and a lower die is arranged on the lower part of the frame, hydraulic rods are embedded on both sides of the top of the lower die, and a limiting mechanism is arranged on one side of the hydraulic rod;

[0007] The limiting mechanism includes a support rod, which passes through both sides of the bottom end of the upper die, and a shock-absorbing spring is sleeved on the outside of the support rod. A permanent magnet block is fixed to one end of the support rod that passes through the lower die, and an electromagnet is embedded in the position of the permanent magnet block inside the lower die. An elastic pad is fixed to one side of the support rod at the bottom end of the upper die, and a limiting plate is connected below the elastic pad. A plurality of corresponding holes are provided on the limiting plate facing the outer wall of the lower die. The upper die and the lower die are respectively composed of a structural frame and a pressing roller, which are driven by a motor and a matching worm gear to rotate the pressing roller, so that the upper die presses the material against the lower die to flatten it and transmit it.

[0008] As a further description of the above technical solution: the upper die forms an elastic structure with the lower die through a shock-absorbing spring, and a sliding structure is formed between the shock-absorbing spring and the support rod. The shock-absorbing spring plays a certain role in shock absorption when the upper die presses the lower die and transfers materials. The support rod is located in the shock-absorbing spring, which facilitates the upper die and the lower die to be aligned and pressed together while avoiding bending and twisting of the shock-absorbing spring.

[0009] As a further description of the above technical solution: connecting blocks are fixed to the front and rear ends of the frame, and limiting grooves are provided on the inner walls of the connecting blocks. Two groups of connecting blocks are arranged, which cooperate with the limiting grooves to have a limiting effect during loading and unloading, thereby improving the correction of material transportation.

[0010] As a further description of the above technical solution: a clamping mechanism is arranged inside the limit groove, and the clamping mechanism includes a clamping block, which is slidably connected inside the limit groove, and a permanent magnet rod is fixed to one side of the outer wall of the clamping block, and an iron core is arranged at one end of the permanent magnet rod that penetrates into the inner wall of the connecting block, and a coil is sleeved on the outside of the iron core, and the iron core and the permanent magnet rod have the same magnetic properties at the fitting end. When the coil is energized, the iron core generates magnetism, and the permanent magnet rod is pushed to make the two corresponding clamping blocks slide relative to each other, thereby clamping and limiting the materials entering and exiting the two ends of the frame, thereby further achieving a limiting effect.

[0011] As a further description of the above technical solution: the clamping mechanism also includes a limit rod, which passes through the interior of the clamping block. The outer wall of the limit rod between the two clamping blocks is sleeved with a telescopic spring. The limit rod allows the clamping block to slide stably to avoid deviation or shaking during the sliding process.

[0012] As a further description of the above technical solution: the clamping block forms a sliding structure between the limit rod and the connecting block, and an elastic structure is formed between the two clamping blocks through a telescopic spring. After the material transmission is completed and the coil is powered off, the telescopic spring pushes the clamping block to reset.

[0013] As a further description of the above technical solution: a slider is fixed to the bottom end of the clamping block, and a sliding groove is opened on the inner wall of the limiting groove corresponding to the position of the slider. The clamping block slides stably in the limiting groove along the sliding groove through the slider, further improving the sliding stability of the clamping block.

[0014] The utility model has the following beneficial effects:

[0015] The utility model discloses a limiting mechanism for a leveling machine. A hydraulic rod lifts an upper die to facilitate the placement of materials and then resets the die. At the same time, an electromagnet is started to absorb a permanent magnet block, thereby driving a support rod to allow the upper die to press a lower die. The upper die is fixed by a hydraulic rod and fixed by magnetic attraction to prevent the hydraulic rod from loosening and affecting the limiting space, resulting in failure to flatten the material. The space between the electromagnet and the permanent magnet block can be changed according to the thickness of the material while still being in magnetic attraction. The mechanism is suitable for limiting and pressing materials of different thicknesses. At the same time, the limiting plate and the corresponding hole are used to contact the pressing roller of the lower die to limit the material to prevent it from sliding to both sides.

[0016] The utility model designs a limiting mechanism for a leveling machine. When materials are discharged and fed, a limiting groove that penetrates a connecting block performs preliminary limiting. Subsequently, the coil is energized to cause the iron core to generate magnetism, thereby pushing the permanent magnetic rod to move, allowing two clamping blocks to clamp and limit the materials. The clamping blocks slide stably through the limiting rod and slide along the sliding groove through the slider, further improving the sliding stability. When the material is transported, the coil is closed, and the clamping blocks are reset under the support of the limiting rod through the telescopic spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1-4 The utility model provides a leveling machine limiting mechanism: comprising a frame 1, an upper die 2 is arranged on the upper part of the frame 1, a lower die 3 is arranged on the lower part of the frame 1, hydraulic rods 4 are embedded on both sides of the top of the lower die 3, and a limiting mechanism 5 is arranged on one side of the hydraulic rod 4;

[0024] The limiting mechanism 5 includes a support rod 502, which passes through both sides of the bottom end of the upper die 2. A shock-absorbing spring 501 is sleeved on the outside of the support rod 502. A permanent magnet block 503 is fixed to one end of the support rod 502 that passes through the lower die 3. An electromagnet 504 is embedded in the position of the permanent magnet block 503 inside the lower die 3. An elastic pad 505 is fixed to one side of the support rod 502 at the bottom end of the upper die 2. A limiting plate 506 is connected below the elastic pad 505. The limiting plate 506 has a plurality of corresponding holes 507 on the outer wall of the lower die 3. The upper die 2 and the lower die 3 are respectively composed of a structural frame and a pressing roller, which are driven by a motor and a matching worm gear to rotate the pressing roller, so that the upper die 2 presses the material against the lower die 3 to flatten it and transmit it.

[0025] As a further implementation scheme of the above technical scheme: the upper die 2 forms an elastic structure with the lower die 3 through the shock-absorbing spring 501, and a sliding structure is formed between the shock-absorbing spring 501 and the support rod 502. The shock-absorbing spring 501 has a certain shock-absorbing effect when the upper die 2 presses the lower die 3 and transfers materials. The support rod 502 is located in the shock-absorbing spring 501, which facilitates the upper die 2 and the lower die 3 to be aligned and pressed together while avoiding bending and twisting of the shock-absorbing spring 501.

[0026] As a further implementation scheme of the above technical scheme: connecting blocks 6 are fixed to the front and rear ends of the frame 1, and limiting grooves 7 are provided on the inner walls of the connecting blocks 6. Two groups of connecting blocks 6 are provided, which cooperate with the limiting grooves 7 to have a limiting effect during loading and unloading, thereby improving the correction of material transportation.

[0027] During specific implementation, the hydraulic rod 4, supported by the lower die 3, lifts the upper die 2 to facilitate the placement of materials and then resets it. At the same time, the electromagnet 504 is started to magnetically attract the permanent magnet block 503, driving the support rod 502 to penetrate the lower die 3, allowing the upper die 2 to fully press the material on the lower die 3 to prevent the hydraulic rod 4 from loosening after stopping. The thickness of the material makes it easier for the electromagnet 504 to magnetically attract the permanent magnet block 503 for compression, thereby further limiting the position and allowing objects of different thicknesses to be placed. The shock-absorbing spring 501 has a certain shock-absorbing property. The lower die 3 pushes the limit plate 506 to contact the lower die 3 through the elastic pad 505, and the limit plate 506 contacts the pressing roller through the corresponding hole 507, further limiting the position to prevent the material from sliding to both sides.

[0028] As a further implementation scheme of the above technical scheme: a clamping mechanism 8 is arranged inside the limiting groove 7, and the clamping mechanism 8 includes a clamping block 801, which is slidably connected inside the limiting groove 7, and a permanent magnet rod 802 is fixed to one side of the outer wall of the clamping block 801, and an iron core 804 is arranged at one end of the permanent magnet rod 802 that penetrates into the inner wall of the connecting block 6, and a coil 803 is sleeved on the outside of the iron core 804. The iron core 804 and the permanent magnet rod 802 have the same magnetic properties at the fitting end. After the coil 803 is energized, the iron core 804 generates magnetism, and the permanent magnet rod 802 is pushed to make the two corresponding clamping blocks 801 slide relative to each other, so as to clamp and limit the materials entering and passing out of the two ends of the frame 1, thereby further achieving a limiting effect.

[0029] As a further implementation scheme of the above technical scheme: the clamping mechanism 8 also includes a limiting rod 805, which passes through the interior of the clamping block 801, and the outer wall of the limiting rod 805 between the two clamping blocks 801 is sleeved with a telescopic spring 806. The limiting rod 805 allows the clamping block 801 to slide stably to avoid deviation or shaking during the sliding process.

[0030] As a further implementation scheme of the above technical scheme: the clamping block 801 forms a sliding structure with the connecting block 6 through the limit rod 805, and the two clamping blocks 801 form an elastic structure through the telescopic spring 806. After the material transmission is completed and the coil 803 is powered off, the telescopic spring 806 pushes the clamping block 801 to reset.

[0031] As a further implementation scheme of the above technical scheme: a slider 9 is fixed to the bottom end of the clamping block 801, and a slide groove 10 is opened on the inner wall of the limiting groove 7 corresponding to the position of the slider 9. The clamping block 801 slides stably in the limiting groove 7 along the slide groove 10 through the slider 9, thereby further improving the sliding stability of the clamping block 801.

[0032] During specific implementation, after the coil 803 is energized, the iron core 804 generates magnetism to repel the permanent magnet rod 802 with the same magnetism, so that the two clamping blocks 801 slide relative to each other to clamp and limit the material. The limiting rod 805 facilitates the stable sliding of the clamping block 801. At the same time, the clamping block 801 slides along the slide groove 10 through the slider 9, further improving the stability of the sliding process. When the material is transported, the coil 803 is disconnected and the clamping block 801 is pushed back to its original position through the telescopic spring 806.
