Description

Technical Field

[0001] The invention relates to the technical field of rolling equipment, in particular to rolling equipment and a rolling method for a bimetallic semi-solid composite plate. Background Art

[0002] Bimetallic semi-solid composite sheet is a new type of material formed by combining two different metal materials through a specific composite technology. It uses liquid / semi-solid casting composite technology to cast a wear-resistant layer of metal when the base material is in a semi-solid state to achieve metallurgical bonding of the two metals. This type of sheet not only has excellent physical and chemical properties, such as high strength, high wear resistance, good corrosion resistance and high temperature stability, but also has a dense interface layer without defects such as cracks and inclusions, achieving a good combination of the two metals. In addition, bimetallic semi-solid composite sheet is also customizable, and different metal materials can be selected for composite according to different usage requirements. Therefore, it has been widely used in industries such as electricity, petroleum, metallurgy, and mining, especially under working conditions that require wear resistance, corrosion resistance, and high temperature stability.

[0003] Chinese patent CN215279195U discloses a metal sheet forming and rolling equipment, which belongs to the field of metal sheet processing technology, including an equipment main body and a rolling roller. The rolling roller is rotatably installed inside the equipment main body, and a first mounting frame is installed at the slot on the left end face of the equipment main body. A movable plate is slidably arranged on the inner wall of the first mounting frame, and a second mounting frame is fixedly installed on the left side of the first mounting frame. Through the arrangement of the second mounting frame, the liquid storage tank, the movable tank, the movable plate, the baffle, the leakage groove and the friction block, the rolling lubricant can be evenly applied to the outer end face of the metal sheet, which is convenient for ensuring the rolling effect of the metal sheet. At the same time, by utilizing the arrangement of the first mounting frame, the movable plate and the screw, the metal sheet can enter the interior of the equipment main body in a straight line, which is convenient for stable rolling processing of the metal sheet.

[0004] As a new type of material, bimetallic semi-solid composite sheet has excellent physical properties and broad application prospects.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] See also Figures 1 to 6In an embodiment of the present invention, a rolling device for a bimetallic semi-solid composite plate comprises a frame 1, on which a plurality of mutually parallel support rollers 38 are rotatably arranged, a support frame 2 is fixedly installed in the middle of the frame 1, first slide grooves 201 are provided on both sides of the support frame 2, first slide seats 6 are slidably installed in the two first slide grooves 201, an upper roller 4 is arranged between the two first slide seats 6, roller shafts 5 are fixedly arranged at both ends of the upper roller 4, and the roller shafts 5 are rotatably connected to the first slide seats 6, and a driving mechanism for driving the roller shaft 5 to rotate is arranged on one side of one of the first slide seats 6. A movable assembly, a lower roller 3 is arranged below the upper roller 4, and both ends of the lower roller 3 are rotatably connected to the support frame 2, an adjustment plate 9 is arranged on the inner side of the support frame 2, and both ends of the adjustment plate 9 are respectively fixedly connected to two first slide seats 6, and an adjustment frame for driving the bimetallic semi-solid composite plate 41 to be rolled to move on the frame 1 is arranged above the frame 1, and a transmission mechanism for driving the adjustment plate 9 to move downward is arranged on the support frame 2, and the adjustment frame is connected to the adjustment plate 9 through the transmission mechanism, so that when the adjustment frame moves to the left, the adjustment plate 9 is driven to move downward through the transmission mechanism; When the machine is in use, the bimetallic semi-solid composite plate 41 to be rolled is first placed on the right side of the frame 1, and then the bimetallic semi-solid composite plate 41 is driven to move to the left by the adjustment frame, so that the left side of the bimetallic semi-solid composite plate 41 moves into between the upper roller 4 and the lower roller 3, and the upper roller 4 is rotated by the driving component, so that the upper roller 4 and the lower roller 3 roll the bimetallic semi-solid composite plate 41 and drive it to move to the left, so that the bimetallic semi-solid composite plate 41 moves to the left side of the frame 1, thereby completing one rolling, and then the adjustment frame is controlled to move to the right, so that the bimetallic semi-solid composite plate 41 is moved to the left side of the frame 1. When the bimetallic semi-solid composite plate 41 moves to the right, it enters between the upper roller 4 and the lower roller 3 again, and drives the upper roller 4 to rotate in the opposite direction, so that the bimetallic semi-solid composite plate 41 moves to the right for leveling, and when the adjustment frame moves to the left, the adjustment plate 9 is driven to move downward through the transmission mechanism, thereby driving the upper roller 4 to move downward, so that the gap between the upper roller 4 and the lower roller 3 is reduced, so that when the bimetallic semi-solid composite plate 41 moves to the left for rolling, the gap between the upper roller 4 and the lower roller 3 is reduced, and this is repeated many times until the bimetallic semi-solid composite plate 41 is rolled to the required thickness;

[0035] In this scheme, the transmission mechanism and the adjustment frame are set up to make the bimetallic semi-solid composite plate reciprocate and pass through the upper roller 4 and the lower roller 3 for multiple times, and the gap between the upper roller 4 and the lower roller 3 is gradually reduced by the transmission mechanism. The bimetallic semi-solid composite plate 41 is rolled when it moves to the left, and the bimetallic semi-solid composite plate 41 is flattened when it moves to the right. The multiple cycles of reciprocating rolling and flattening process help to eliminate the residual stress and micro-deformation inside the material and improve the shape stability of the plate. Compared with the traditional large deformation rolling, the small reduction and multiple rolling strategy adopted in this scheme reduces the single deformation of the bimetallic semi-solid composite plate, so the force required to drive the deformation of the bimetallic semi-solid composite plate is also smaller, which can reduce the power of the device driving mechanism, thereby reducing the production cost of the equipment.

[0036] It should be noted that when the adjustment frame pushes the bimetallic semi-solid composite plate 41 to move, it only pushes a small part of the bimetallic semi-solid composite plate 41 into between the upper roller 4 and the lower roller 3, and the adjustment frame stops moving. The subsequent movement of the bimetallic semi-solid composite plate 41 is driven by the rotation of the upper roller 4.

[0038] In this embodiment, preferably, the adjustment frame includes a cross bar 15 and a longitudinal bar 16, and two cross bars 15 and two longitudinal bars 16 are provided. The two ends of the cross bar 15 are respectively fixedly connected to the ends of the two longitudinal bars 16, and the two cross bars 15 and the two longitudinal bars 16 form a rectangular structure. The four corners inside the adjustment frame are fixedly installed with positioning plates 17, and one side of the positioning plate 17 is provided with an inclined surface 1701; through the setting of the positioning plate 17, when the positioning plate 17 pushes the bimetallic semi-solid composite plate 41 to move, if the bimetallic semi-solid composite plate 41 is offset, the inclined surface 1701 of the positioning plate 17 can push the bimetallic semi-solid composite plate 41 to move, so that the bimetallic semi-solid composite plate 41 will not extend from the frame 1.

[0039] See also Figures 5 to 9In the embodiment of the present invention, the transmission mechanism includes an adjusting rod 11, a nut 10 and a first gear 12. The adjusting rod 11 passes through the top wall of the support frame 2, and the adjusting rod 11 is rotatably connected to the support frame 2. The nut 10 is fixedly installed in the middle of the adjusting plate 9. The bottom of the adjusting rod 11 is provided with a thread, and the adjusting rod 11 is threadedly connected to the nut 10. The top end of the adjusting rod 11 is sleeved with a one-way bearing 13, and the one-way bearing 13 is sleeved with a first gear 12. The first gear 12 is connected to the adjusting rod 11 in a one-way transmission through the one-way bearing 13; the inner ring of the one-way bearing 13 is fixedly connected to the adjusting rod 11, and the outer ring of the one-way bearing 13 is fixedly connected to the first gear 12, so that the first gear 12 rotates in one direction When the first gear 12 rotates in the opposite direction, it can drive the adjusting rod 11 to rotate through the one-way bearing 13. When the first gear 12 rotates in the opposite direction, it only drives the outer ring of the one-way bearing 13 to rotate, and the inner ring of the one-way bearing 13 does not rotate, so that the adjusting rod 11 does not rotate; the transmission mechanism also includes a driving rod 14, a connecting frame 19 and a connecting seat 18. A plurality of first tooth blocks 1401 are fixedly arranged on the side of the driving rod 14 close to the first gear 12. The first tooth blocks 1401 are adapted to the first gear 12. The end of the driving rod 14 away from the first gear 12 is fixedly connected to the connecting frame 19. The connecting seats 18 are fixedly installed on the two cross bars 15. The bottom end of the connecting frame 19 passes through the connecting seat 18, and the connecting frame 19 and the connecting seat 18 are slidably matched.

[0040] In this embodiment, preferably, a guide column 39 is fixedly installed on one side of the top of the connecting frame 19, and a limiting cylinder 40 is fixedly installed on the top of the supporting frame 2. The guide column 39 passes through the limiting cylinder 40, and the guide column 39 and the limiting cylinder 40 are slidably matched; thereby limiting the movement of the connecting frame 19, so that the connecting frame 19 can only slide horizontally.

[0041] In this embodiment, preferably, a second slide groove 701 is opened on the inner side of the first mounting plate 7, a T-shaped slide bar 21 is fixedly installed on the outer side of the cross bar 15, and the T-shaped slide bar 21 is slidably set in the second slide groove 701. A second gear 20 is fixedly sleeved on the roller shaft 5, and the second gear 20 is set between the first mounting plate 7 and the first slide seat 6. A plurality of second tooth blocks 1501 are fixedly set in the middle of the top end of the cross bar 15, and the second gear 20 is adapted to the second tooth block 1501; through the setting of the T-shaped slide bar 21 and the second slide groove 701, when the first slide seat 6 moves up and down, it can pass through the first mounting plate 7 and the T-shaped slide bar 21 drive the adjustment frame to move up and down, so that when the adjustment frame moves, the second tooth block 1501 can mesh with the second gear 20, and elastic limiting components are arranged on both sides of the top of the frame 1, and the elastic limiting components include a second mounting plate 37, a connecting cylinder 32 is fixedly mounted on the second mounting plate 37, a second slide seat 34 is slidably mounted inside the connecting cylinder 32, a spring 33 is arranged inside the connecting cylinder 32, and the second slide seat 34 is elastically connected to the inner side wall of the connecting cylinder 32 through the spring 33, and a connecting column 35 is fixedly mounted on one side of the second slide seat 34, and the connecting column 35 passes through the connecting cylinder 32. On one side wall of the connecting cylinder 32, a pressure plate 36 is fixedly installed at one end of the connecting column 35 away from the second slide seat 34; when the roller shaft 5 rotates, the roller shaft 5 drives the second gear 20 to rotate, and when the second gear 20 rotates, it drives the adjustment frame to move through the second tooth block 1501. When the adjustment frame moves to the contact with the pressure plate 36 and compresses the spring 33 for a distance, the second tooth block 1501 is just separated from the second gear 20, so that when the roller shaft 5 rotates subsequently, the adjustment frame will not be driven to move through the second tooth block 1501. When the roller shaft 5 rotates in the opposite direction, under the elastic action of the elastic limit assembly, the second tooth block 1501 is meshed with the second gear 20 again, so that When the second gear 20 rotates in the opposite direction, the second gear block 1501 drives the adjustment frame to move in the opposite direction. The outer diameter of the second gear 20 is the same as the outer diameter of the upper roller 4, so that when the roller shaft 5 drives the adjustment frame to move through the second gear 20, the moving speed of the adjustment frame is the same as the moving speed of the bimetallic semi-solid composite plate 41 between the upper roller 4 and the lower roller 3, thereby avoiding the speed difference that causes the bimetallic semi-solid composite plate 41 to deform. Only by setting a motor 8, the rotation of the upper roller 4, the movement of the adjustment frame and the lifting of the upper roller 4 are realized, which reduces the production cost of the equipment, improves the synchronization of the equipment operation, and reduces the failure rate;When the adjustment frame moves to the left, the adjustment frame drives the connecting frame 19 to move to the left through the connecting seat 18, and the connecting frame 19 drives the driving rod 14 to move to the left when it moves to the left. When the driving rod 14 moves to the left, it drives the first gear 12 to rotate through the first gear block 1401. When the first gear 12 rotates, it drives the adjustment rod 11 to rotate through the one-way bearing 13, thereby driving the adjustment rod 11 to move downward, so that the adjustment plate 9 drives the upper roller 4 to move downward. When the adjustment frame moves to the right, the first gear 12 cannot drive the adjustment rod 11 to rotate through the one-way bearing 13, and the upper roller 4 does not move. ;
