Description

Technical Field

[0001] The present application relates to the technical field of metal rolling, and in particular to a universal rolling mill. Background Art

[0002] As an important metal plastic processing equipment, the universal rolling mill occupies a pivotal position in the steel industry due to its unique structural design and wide application fields. The universal rolling mill is mainly composed of a pair of horizontal rollers and a pair of vertical rollers as the main frame. The axes of the four rollers are located in the same plane, which can process the rolled piece on four sides, and a two-roller horizontal rolling mill is used as an auxiliary frame. The universal rolling mill is mainly used for rolling various types of steel, such as H-shaped steel, rails and I-beams. Steel rolling is a complex metal processing technology, and its steps involve multiple links. The post-pressing treatment is particularly important. The rolled metal billet needs to be cooled quickly to maintain its dimensional stability.

[0003] The existing technology still has the following problems: 1. The cooling process after steel rolling by a universal rolling mill is a crucial link, which directly affects the organization, performance and final quality of the steel. The cooling is carried out by controlling the cooling water to spray the outer surface of the rolled steel. However, the existing universal rolling mill has uneven cooling water spraying, which causes uneven cooling of the steel, leading to instability in the strength, toughness, plasticity, etc. of the steel, and may even cause the steel to break or fail during use. In addition, the cooling water during cooling is difficult to reuse, and the reused cooling water is difficult to cool quickly, which affects the cooling effect of the cooling water on the rolled steel.

[0004] 2. The existing universal rolling mill cannot correct the position of the workpiece after pressing. After the rolled steel is cooled, the workpiece is still very easy to deform due to the rapid cooling. The deformation of the workpiece is easy to cause position displacement during transportation. When the workpiece is offset during transportation, the tilt of the rolled steel may cause a collision between the rolled steel and the conveying equipment, thereby causing wear or scratches on the surface of the rolled steel. The use of a rigid correction mechanism will also cause damage to the rolled steel workpiece, and manual observation of the transportation situation is required, wasting the staff's time.

A water tank 6 is provided in the middle part of the rolling mill body 1. Ventilation grooves are provided on both sides of the inner cavity of the water tank 6 where the rolling mill body 1 is located. When rolling steel, the workpiece is placed between the pressing rollers 26. The pressing rollers 26 are driven to rotate by the operation of the first motor 27 so that the workpiece passes through the two pressing rollers 26 for pressing. After being pressed by the pressing component 2, the workpiece is cooled by spraying cooling water through the cooling component 3. At the same time, the baffle 4 and the water tank 6 are used to store cooling water. The transmission component 5 is used to transmit the workpiece and prevent the workpiece from tilting. The position of the tilted workpiece can be corrected to prevent the workpiece from shifting. The second pressing frame 24 is moved on the first threaded rod 23 by rotating the first threaded rod 23. At this time, the limit rod 25 slides in the inner cavity of the first pressing frame 21, so that the distance between the two pressing rollers 26 changes, so that it can be adjusted according to actual pressing requirements, so as to facilitate the production of workpieces of different specifications.

[0023] See also Figure 2 and Figure 4As shown, the cooling assembly 3 includes a cooling rack 31, the inner wall of the upper end of the cooling rack 31 is evenly provided with water spray heads 32, the outer surface of the cooling rack 31 is wrapped with a water pipe 33, the inner cavity of the water tank 6 is provided with a cooling mechanism 34, the outer surface of the rolling mill body 1 is provided with an air cooling mechanism 35, the cooling rack 31 and the inner wall of the rolling mill body 1 are fixedly connected, the water pipe 33 and the water spray head 32 are connected, and the bottom end of the water pipe 33 is located in the inner cavity of the water tank 6, the inner cavity of the water tank 6 is provided with a water pump, the water pipe 33 and the water pump are sleeved, the air cooling mechanism 35 is located at the ventilation slot, and the cooling rack 31 is located above the inner cavity of the water tank 6 to ensure that the cooling water sprayed by the water spray head 32 can be collected in the inner cavity of the water tank 6 for secondary use. When cooling the workpiece, the workpiece passes through the inner cavity of the cooling rack 31 and is cooled by the pump. The cooling water in the bottom of the inner cavity of the water storage tank 6 is driven into the water pipe 33, and finally sprayed out from the inner cavity of the water pipe 33 from the water nozzle 32. Since the inner cavity of the cooling rack 31 is provided with a water nozzle 32, cooling water can be sprayed on all sides of the workpiece to make the outer surface of the workpiece evenly cooled. At the same time, the cooling mechanism 34 collects the sprayed cooling water, so that the used cooling water is shaken above the cooling mechanism 34 and fully contacts with the air, and when a certain amount is collected, it is dispersed and flows into the bottom of the water storage tank 6, and the cooling water on the cooling mechanism 34 and the cooling water at the bottom of the water storage tank 6 are air-cooled by the air cooling mechanism 35. The cooling water is divided into two parts by the cooling mechanism 34, and the cooling water in use obtains a good cooling effect, thereby facilitating the recycling of cooling water and saving water resources.

[0024] See also Figure 4 , Figure 5 and Figure 6As shown, the cooling mechanism 34 includes a partition 341, a diverter 342 is fixedly installed in the inner cavity of the partition 341, a diverter ring 343 is fixedly installed in the inner cavity of the diverter 342, a support frame 344 is fixedly installed in the inner cavity of the rolling mill body 1, a first slide bar 345 is fixedly installed at both ends of the support frame 344, a first spring 346 is sleeved on the outer surface of the first slide bar 345, a convex block 347 is fixedly installed in the middle part of the support frame 344, a diverter hole is opened on the outer surface of the diverter ring 343, the partition 341 and the first slide bar 345 are slidably connected, and the partition 341 and the water storage tank are fixedly connected. 6 is slidably connected, there is a gap between the partition 341 and the protrusion 347, the first spring 346 is located between the partition 341 and the support frame 344, the diverter 342 is located on both sides of the support frame 344, so that the water in the diverter 342 can flow into the bottom end of the water storage tank 6, the top of the protrusion 347 is flush with the top of the ventilation slot, the partition 341 is located above the ventilation slot, and the height of the diverter 342 is lower than the top of the water storage tank 6, so as to prevent water from overflowing from the inner cavity of the water storage tank 6 and not flowing from the inner cavity of the diverter 342 into the bottom of the water storage tank 6 for collection, so as to ensure that when the partition 341 moves down The partition 341 is always above the ventilation slot to prevent the cooling water above the partition 341 from flowing out of the ventilation slot. When the cooling water is circulated, the cooling water sprayed by the water spray head 32 is collected above the partition 341. That is, the used cooling water is initially cooled on the partition 341 on the inner cavity of the water storage tank 6. When the cooling water accumulates to a certain height, it submerges the top of the diverter 342. At this time, the cooling water flows from the diverter hole on the diverter ring 343 to the bottom of the water storage tank 6 for secondary collection and cooling. The cooling water is divided and flows down through the diverter ring 343 so that the cooling water and air are fully connected. The partition 341 is touched, which is convenient for rapid cooling. When the cooling water flows into the top of the partition 341, the partition 341 is subjected to the impact of the cooling water to cause the partition 341 to drop, and the partition 341 squeezes the first spring 346. At the same time, the elastic force of the first spring 346 causes the partition 341 to shake, and the partition 341 slides back and forth on the first slide bar 345, so that the cooling water above the partition 341 fluctuates, so that the collected cooling water can fully contact with the air, and the air cooling mechanism 35 can drive the flow speed of the air, thereby improving the cooling effect, and cooling the cooling water quickly, which is convenient for subsequent recycling.

The fixed plate 351 is fixedly connected to the rolling mill body 1. When the used cooling water is cooled, the air cooling mechanism 35 drives the second threaded rod 352 to rotate on the inner wall of the fixed plate 351, and the rotation of the second threaded rod 352 drives the movable seat 353 to move back and forth on the second threaded rod 352. One end of the movable seat 353 drives the belt 356 to move on the rotating rod 355, so that the belt 356 moves back and forth. The movement of the belt 356 drives the first connecting block 357 and the second connecting block 359 to move respectively, so that the first fan 358 and the second fan 3511 reciprocate at the upper and lower ends of the partition 341. The operation of the first fan 358 makes the diverter bucket 342 form a The water under the stream is cooled, and the cooling water collected for the second time at the bottom of the water tank 6 is cooled. At the same time, the second fan 3511 cools the cooling water collected for the first time above the partition 341, and cooperates with the up and down shaking of the partition 341, so that the cooling water on the partition 341 and the water flowing into the bottom of the water tank 6 can increase the contact area with the air, increase the air flow rate at the upper and lower ends of the partition 341, and can also effectively improve the cooling efficiency, so that the cooling water at the bottom of the water tank 6 can obtain a good cooling effect, avoid direct recycling and cause incomplete cooling of the rolled steel workpiece, and prevent incomplete cooling from affecting the quality of rolled steel production.

Pressing the button 5711 controls the speaker 5712 to sound an alarm. The pressure plate 5710 is located between the buttons 5711. There is a gap between the button 5711 and the pressure plate 5710. The connecting ring 574 is slidably connected to the support plate 55. When the rolled steel is tilted due to placement or deformation, it will contact the guide cylinder 577 when moving on the rotating cylinder 572. Before use, by rotating the fourth threaded rod 5 78 drives the correction block 576 to slide on the correction frame 571, so that the spacing between the two correction blocks 576 at parallel positions is equal to the width of the rolled steel. When the rolled steel passes through the larger opening of the correction block 576, it is guided by the guide cylinder 577 so that the rolled steel can be clamped between the correction blocks 576 at most. At the same time, the correction block 576 as a whole adopts flexible limit to prevent damage to the rolled steel due to excessive rigidity. When the rolled steel workpiece and the guide cylinder 577 contact, a certain pressure is applied to the correction block 576. At this time, the correction block 576 drives the correction frame 571 to move to a certain position. The movement of the correction frame 571 drives the compression of the second spring 575. At this time, the first slider 53 slides in the inner cavity of the first slide groove 52. At the same time, under the elastic force of the second spring 575, the correction frame 571 quickly returns to the away position.Thus, the middle part of the rolled steel workpiece is ensured to be too rigid when in contact with the guide cylinder 577, resulting in damage to the outer surface of the rolled steel being shaped. At the same time, when the correction frame 571 has a large displacement, one end of the correction frame 571 drives the second fixed block 579 to move, and one end of the second fixed block 579 drives the pressure plate 5710 to squeeze the button 5711. At this time, the speaker 5712 sounds an alarm to remind the staff to check the pressed workpiece to prevent unqualified workpieces from entering the market.

[0027] See also Figure 8 , Fig. 9 and Fig.11 As shown, the adjustment mechanism 54 includes a third connecting block 541, the lower surface of the third connecting block 541 is fixedly connected to the first slider 53, the inner cavity of the third connecting block 541 is rotatably connected to the third threaded rod 542, the upper surface of the third connecting block 541 is slidably connected to the second slider 543, and the two ends of the second slider 543 are fixedly installed with driving rods 544, and the four corners of the third connecting block 541 are fixedly installed with storage rods 545, and the inner cavity of the storage rod 545 is slidably connected with a lifting rod 546, and the top of the lifting rod 546 is fixedly installed with 547, and the lower surface of 547 is fixedly installed with an adjustment block 548, and the outer surface of the adjustment block 548 is provided with a driving groove 549, and the driving groove 549 is inclined. The driving groove 549 and the driving rod 544 are slidably connected. By adjusting the adjustment mechanism The height of 54 enables the height of the correction mechanism 57 to be adjusted, so that the workpiece can directly contact the rotating cylinder 572 after pressing according to the different steel rolling models. When adjusting the height of the correction mechanism 57, the second slider 543 is caused to slide on the third connecting block 541 by rotating the third threaded rod 542. The sliding of the second slider 543 drives the driving rod 544 to slide in the inner cavity of the driving groove 549 on the adjusting block 548. The sliding of the driving rod 544 drives the lifting rod 546 to move in the inner cavity of the storage rod 545. One end of the lifting rod 546 drives 547 to move up and down. At this time, the height of the correction frame 571 changes, and the second sliding rod 573 slides in the inner cavity of the second sliding groove 56. The height of the correction mechanism 57 can be adjusted according to actual needs, which is convenient for adjustment according to the specifications of the pressed steel.

[0028] In summary, when rolling steel, the workpiece is placed between the pressing rollers 26, and the first motor 27 drives the pressing rollers 26 to rotate so that the workpiece passes between the two pressing rollers 26 for pressing. After being pressed by the pressing assembly 2, the workpiece is cooled by spraying cooling water through the cooling assembly 3. At the same time, the baffle 4 and the water tank 6 are used to store cooling water. The transmission assembly 5 is used to transmit the workpiece and prevent the workpiece from tilting. The position of the tilted workpiece can be corrected to prevent the workpiece from shifting. When cooling the workpiece, the workpiece passes through the inner cavity of the cooling rack 31, and the workpiece is driven by the pump to cool the workpiece in the water tank 6. The cooling water at the bottom of the cavity enters the water pipe 33, and is finally sprayed out from the water spray head 32 from the inner cavity of the water pipe 33. Since the inner cavity of the cooling rack 31 is provided with the water spray head 32, the cooling water can be sprayed on all surfaces of the workpiece to make the outer surface of the workpiece evenly cooled. At the same time, the cooling mechanism 34 collects the sprayed cooling water, so that the used cooling water is shaken above the cooling mechanism 34 and fully contacts the air. When a certain amount of cooling water is collected, it is dispersed and flows into the bottom of the water storage tank 6, and the cooling water on the cooling mechanism 34 and the cooling water at the bottom of the water storage tank 6 are cooled by air through the air cooling mechanism 35. In cooperation with the cooling mechanism 34, The cooling water is divided into two parts, and the cooling water in use has a good cooling effect, which is convenient for the recycling of cooling water and saves water resources. When the rolled steel is tilted due to placement or deformation, it will contact the guide cylinder 577 when moving on the rotating cylinder 572. Before use, the fourth threaded rod 578 is rotated to drive the correction block 576 to slide on the correction frame 571, so that the distance between the two correction blocks 576 at parallel positions is equal to the width of the rolled steel. When the rolled steel passes through the larger opening of the correction block 576, it is guided by the guide cylinder 577 so that the rolled steel is clamped between the correction blocks 576 at most, and the correction The positive block 576 adopts flexible limiting as a whole to prevent damage to the rolled steel due to excessive rigidity. When the rolled steel workpiece contacts the guide cylinder 577, a certain pressure is applied to the correction block 576. At this time, the correction block 576 drives the correction frame 571 to move to a certain position. The movement of the correction frame 571 drives the second spring 575 to be compressed. At this time, the first slider 53 slides in the inner cavity of the first slide groove 52. At the same time, under the elastic force of the second spring 575, the correction frame 571 quickly returns to the away position, thereby positioning the rolled steel workpiece in the middle part to ensure that the rigidity is too strong when in contact with the guide cylinder 577, which causes the outer surface of the rolled steel to be damaged.
