Description

Technical Field

[0001] The utility model relates to the technical field of flat steel processing, in particular to a flat steel forming and rolling device. Background Art

[0002] Flat steel refers to steel with a width of 12 - 300 mm, a thickness of 3 - 60 mm, and a rectangular cross-section with slightly rounded edges. Flat steel can be finished steel, or it can be used as the blank for welded pipes and the thin slab for double-rolled thin sheets.

[0003] When flat steel is being produced and processed, it is placed on a pressing device. The upper and lower rollers on the pressing device can extrude and process the flat steel when rotating. Most of the upper and lower rollers are fixedly installed on the pressing device, which makes the distance between the upper and lower rollers fixed. It is difficult to adjust the distance between the upper and lower rollers, so that the pressing device cannot process flat steel of different specifications, thus affecting the adaptability of the pressing device. When the flat steel enters between the upper and lower rollers, the operator needs to manually lift the flat steel. The weight of the flat steel makes it inconvenient to move, which not only increases the working intensity of the operator but also affects the processing efficiency of the flat steel. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the distance between the upper and lower rollers on the pressing device in the prior art is not easy to adjust, and to propose a flat steel forming and rolling device.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A flat steel forming and rolling device includes a base, and a lower roller and an upper roller for processing flat steel are arranged on the base. A clamping seat, a blanking plate, and a limiting rod are fixedly installed on the base. The lower roller is arranged between two clamping seats. A guide rod is fixedly installed in the clamping seat, and a rack is slidably sleeved on the guide rod. The upper roller is arranged between two racks. A driving component for driving the rack is installed in the clamping seat. A supporting plate for supporting the flat steel is slidably sleeved on the limiting rod.

[0007] Preferably, the clamping seats are vertically arranged on both sides of the base, and the two corresponding guide rods are vertically arranged.

[0008] Preferably, the driving component includes a motor fixedly installed on one of the clamping seats. The output end of the motor is fixedly connected with a rotating shaft that is in transmission connection with the rack. The rotating shaft is horizontally arranged, and a gear meshed with the rack is fixedly installed on the rotating shaft.

[0009] Preferably, a positioning rod is placed on the clamping seat, and a limiting plate for supporting the upper roller is integrally connected between the two positioning rods. A locking bolt corresponding to the clamping seat is threadedly connected to the limiting plate.

[0010] Preferably, a support rod is fixedly installed on the base, and a slider is slidably sleeved on the support rod. A spring cooperating with the support rod is welded between the slider and the base. A connecting rod is connected between the slider and the support plate. A hydraulic cylinder connected to the slider is fixedly installed on the base.

[0011] Preferably, the support rod is horizontally arranged, the spring is sleeved on the support rod, and both ends of the connecting rod are pin-connected to the slider and the support plate respectively.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. The present utility model drives the rotation of the rotating shaft and the gear through the driving of the motor. When the gear rotates, it pulls the rack. When the rack moves, it can adjust the height of the upper roller, so that the upper roller and the lower roller can process flat steel of different specifications, thereby improving the adaptability of the processing equipment.

[0014] 2. The present utility model makes the slider pull the connecting rod when moving through the telescopic movement of the output end of the hydraulic cylinder. The position difference generated when the connecting rod deflects can pull the support plate, making it more convenient for the flat steel to enter between the upper roller and the lower roller. This not only reduces the working intensity of the operator but also improves the efficiency of processing the flat steel. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Refer to Figures 1 - 3, A flat steel forming and rolling device, including a base 1, and a lower roller 2 and an upper roller 3 for processing flat steel are provided on the base 1. After the lower roller 2 and the upper roller 3 are electrified, they can process flat steel. This technical solution is prior art and will not be elaborated here;

[0021] A clamping seat 4, a blanking plate 5, and a limiting rod 6 are fixedly installed on the base 1. The lower roller 2 is arranged between two clamping seats 4. A guide rod 8 is fixedly installed in the clamping seat 4, and a rack 9 is slidably sleeved on the guide rod 8. The guide rod 8 guides the rack 9, enabling the rack 9 to smoothly pull the upper roller 3 when moving;

[0022] The clamping seats 4 are vertically arranged on both sides of the base 1, and the two corresponding guide rods 8 are vertically arranged. The upper roller 3 is arranged between the two racks 9. A driving component for driving the rack 9 is installed in the clamping seat 4;

[0023] The driving component includes a motor 10 fixedly installed on one of the clamping seats 4. The output end of the motor 10 is fixedly connected to a rotating shaft 11 that is in transmission connection with the rack 9. The rotating shaft 11 is horizontally arranged, and a gear 12 meshed with the rack 9 is fixedly installed on the rotating shaft 11. When it is necessary to adjust the height of the lower roller 2 and the upper roller 3, the output end of the motor 10 drives the rotating shaft 11 to rotate. When the rotating shaft 11 rotates, it drives the gear 12 to pull the meshed rack 9. When the rack 9 moves on the guide rod 8, it drives the upper roller 3 to rise and fall, enabling the height of the lower roller 2 and the upper roller 3 to be adjusted according to the specifications of the flat steel, thereby improving the adaptability of the processing equipment;

[0024] A positioning rod is placed on the clamping seat 4, and a limiting plate for supporting the upper roller 3 is integrally connected between the two positioning rods. A locking bolt corresponding to the clamping seat 4 is threadedly connected to the limiting plate. Press the limiting plate to make the limiting plate drive the positioning rod to extend into the clamping seat 4, and use the locking bolt to connect the limiting plate and the clamping seat 4, so that the limiting plate can support the upper roller 3;

[0025] A support plate 13 for supporting the flat steel is slidably sleeved on the limiting rod 6. A support rod 7 is fixedly installed on the base 1, and a slider 14 is slidably sleeved on the support rod 7. A spring 15 that cooperates with the support rod 7 is welded between the slider 14 and the base 1. The limiting rod 6 guides the support plate 13, and the support rod 7 guides the slider 14, enabling the slider 14 to smoothly pull the connecting rod 17 when moving;

[0026] A connecting rod 17 is connected between the slider 14 and the support plate 13. A hydraulic cylinder 16 connected to the slider 14 is fixedly installed on the base 1. The support rod 7 is horizontally arranged, and the spring 15 is sleeved on the support rod 7. The two ends of the connecting rod 17 are respectively pin-connected to the slider 14 and the support plate 13;

[0027] When the flat steel enters between the lower roller 2 and the upper roller 3, the output end of the hydraulic cylinder 16 drives the slider 14 to slide on the support rod 7. When the slider 14 moves, it pulls the connecting rod 17. When the connecting rod 17 moves, it adjusts the height of the support plate 13, so that the support plate 13 can adjust the height of the flat steel, which not only reduces the working intensity of the operator but also improves the processing efficiency of the flat steel.

[0028] It should be noted that the specific model specifications of the lower roller 2, the upper roller 3, the motor 10, and the hydraulic cylinder 16 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of the present utility model can be elaborated through the following operation methods:

[0030] Adjust the height of the upper roller 3 according to the specifications of the flat steel;

[0031] The output end of the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the gear 12 to pull the engaged rack 9. When the rack 9 slides on the guide rod 8, it drives the upper roller 3 to move, so that when the upper roller 3 moves up or down, its own height is adjusted.

[0032] After the distance between the upper roller 3 and the lower roller 2 is adjusted, press the limit plate, so that the limit plate drives the positioning rod to extend into the clamping seat 4, and use the limit plate to connect the locking bolt to the support.

[0033] Transfer the flat steel to the support plate 13;

[0034] The telescopic output end of the hydraulic cylinder 16 drives the slider 14 to slide on the support rod 7, and the spring 15 is stressed. When the slider 14 moves, it pulls the connecting rod 17. The position difference generated when the connecting rod 17 deflects can pull the support plate 13. When the support plate 13 slides on the limit rod 6, its own height is adjusted, so that the flat steel in the support plate 13 can fall between the upper roller 3 and the lower roller 2.

[0035] After the upper roller 3 and the lower roller 2 are electrified, the flat steel is processed, and the processed flat steel is discharged through the blanking plate 5.

[0036] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
