[0002] Non-ferrous metal alloy rolling refers to the process of processing thick materials into thinner sheet structures through rolling operations.

[0003] In order to solve the problem that the distance between the two calendering rollers becomes larger due to the calendering of different thicker metals by calendering rollers for a long time, the prior art (Chinese invention patent with announcement number CN117548488B) discloses a calendering processing equipment for non-ferrous metal alloys, which can position the calendering rollers at a certain position and continuously and stably perform calendering operations on the metal by setting a positioning structure; although the device can achieve stable calendering of the material, the ductility of some non-ferrous metal alloys (such as aluminum alloys, copper alloys, etc.) is relatively low.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This scheme sets a longitudinal stress applying unit, and the roller body rotates to drive the pressing part to rotate, so that the pressing part can clamp the material and pull the material to move. The longitudinal stress is applied to pre-stretch the material before calendering, and the material is pulled slightly along its length direction. The tendency of the material to expand laterally during the calendering process can be reduced in advance, thereby reducing the concentration of lateral stress. After the longitudinal stress is applied, the lateral stress of the material during the calendering process will be partially offset, especially in the edge area, where stress concentration is easily formed, thereby reducing the phenomenon of cracks and delamination. The pre-stretched material has a smaller lateral deformation during calendering, and the edge part is less likely to be damaged due to excessive stress.

[0018] (2) This scheme sets a lightweight pre-stressing unit, and the pre-stressing roller can pre-stress the material before formal calendering, which can slightly reduce the thickness of the material and make the pressure evenly distributed on the entire material, thereby avoiding excessive deformation caused by one-time calendering, especially avoiding excessive lateral expansion and stress concentration at the edge of the material. The edge pre-stressing part then performs a second pre-stressing on the edge of the pre-stressed material, which can effectively adjust the stress distribution at the edge. Since the edge is subjected to a large lateral stress during the calendering process, the pre-stressing can release part of the stress concentration in advance, avoiding cracks or delamination at the edge due to excessive stress in subsequent calendering. The flanges on the second outer surface of the roller body can cause depressions on the surface of the material when pressed on the material. By pressing out depressions on the surface, the material can have greater flexibility and ductility, and the stress concentration in the depression area of ​​the material can be transferred to other areas, thereby alleviating the stress concentration inside the material and reducing the risk of cracks or deformation on the surface of the material.

[0019] (3) This solution provides a lubrication unit and sprays lubricant on the surface of the material to be calendered, thereby reducing the friction between the edge and the pressing roller and avoiding local stress concentration caused by excessive friction. The lubricant is evenly distributed on the material surface through the material distribution component, thereby preventing uneven stress on the edge caused by insufficient local lubrication and preventing the occurrence of cracks and stratification.

[0031] See also Figures 1 to 8 A rolling processing equipment for non-ferrous metal alloys, comprising two side plates 1 and a rolling unit 2 connected to the side plates 1, a longitudinal stress applying unit 3 is connected between the two side plates 1, and the longitudinal stress applying unit 3 comprises a bracket 2 31 fixedly connected to one side of one of the side plates 1, two gears 2 33 rotatably connected to one side of one of the side plates 1, two rollers 1 34 rotatably connected between the two side plates 1, two grindstones 35 symmetrically fixed between the two side plates 1, arc grooves 36 provided on opposite sides of the two support plates, a clamping portion 37 connected to the two rollers 1 34, a motor 2 32 fixedly connected to one side of the bracket 2 31 and having an output shaft fixedly connected to one of the gears 2 33, and a limiting portion 38 connected between the two side plates 1, and the two gears 2 33 are meshed.

[0032] Two movable grooves five 341 are symmetrically opened inside the two roller bodies 34, and two clamping parts 37 are symmetrically arranged inside a single roller body 34, and the two clamping parts 37 are respectively located in the two movable grooves five 341, one end of the two clamping parts 37 penetrates the roller body 34 and extends outward, a screw rod 342 is rotatably connected inside the roller body 34, and the screw rod 342 is screwed into the two clamping parts 37, and a guide rod 343 is also fixed in the two movable grooves five 341, and the two clamping parts 37 are movably sleeved on the outside of the guide rod 343.

[0033] The limiting portion 38 includes a motor 381 fixedly connected to the upper end of one of the side plates 1, two movable grooves 382 opened on opposite sides of the two side plates 1, a screw rod 383 rotatably connected to one of the movable grooves 382, ​​and two pressure seats 384 symmetrically arranged between the two side plates 1, the output shaft of the motor 381 is fixedly connected to one end of the screw rod 383, and the two ends of the two pressure seats 384 are slidably connected in the movable groove 382, ​​and the screw rod 383 is screwed in the two pressure seats 384.

[0034] The calendering unit 2 includes a bracket 21 fixedly connected to one side of one of the side plates 1, a motor 22 fixedly connected to one side of the bracket 21, two gears 23 rotatably connected to one side of one of the side plates 1, and two calendering rollers 24 rotatably connected between the two side plates 1, the two gears 23 are meshed with each other, and the output shaft of the motor 22 is fixedly connected to one of the gears 23, and one end of the two calendering rollers 24 passes through the side plate 1 and is respectively fixedly connected to one side of the two gears 23.

[0035] By adopting the above technical scheme, when the material passes between the two calendering rollers 24, the motor 22 works to drive the two gears 23 to rotate, and the rotation of the two gears 23 drives the two calendering rollers 24 to rotate to calender the material. The motor 32 works to drive the two gears 23 to rotate, and the rotation of the two gears 23 can drive the two roller bodies 1 34 to rotate. The rotation direction of the two roller bodies 1 34 is opposite to the rotation direction of the two calendering rollers 24. When the two roller bodies 1 34 rotate, the outer surface of the roller body 1 34 cannot contact the surface of the material, but the clamping part 37 inside the roller body 1 34 can contact the surface of the material. When the two clamping parts 37 rotate to the vicinity of the material and are about to contact the material, the motor 381 works to drive the screw rod 1 383 to rotate, and the screw rod 1 383 rotates to drive the two pressure seats 384 to move toward each other, the distance between the two pressure seats 384 becomes smaller and the material is clamped to prevent the material from moving, and the motor 22 also stops working. The calendering roller 24 stops conveying and calendering the material, and the two clamping parts 37 clamp the material and pull the material to move in the opposite direction of the calendering roller 24. Longitudinal stress is applied to pre-stretch the material before calendering, and the material is pulled slightly along its length direction, which can pre-reduce the tendency of the material to expand laterally during the calendering process, thereby reducing the concentration of lateral stress. After the longitudinal stress is applied, the lateral stress of the material during the calendering process will be partially offset, especially in the edge area, where stress concentration is prone to occur, thereby reducing the phenomenon of cracks and delamination. The pre-stretched material has a smaller lateral deformation during calendering, and the edge part is less likely to be damaged due to excessive stress. By rotating the screw 342, the distance between the two clamping parts 37 inside the roller body 34 can be adjusted, and the length of the two clamping parts 37 extending from the roller body 34 can also be adjusted, so as to facilitate the stretching of materials of different thicknesses.

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, a lightweight prestressing unit 4 is also connected between the two side plates 1, and the lightweight prestressing unit 4 includes two movable grooves 41 respectively opened in the two side plates 1, a screw rod 43 rotatably connected in one of the movable grooves 41, and two prestressing components connected between the two side plates 1 and symmetrically arranged, and the prestressing components include two movable seats 42 respectively slidably connected in the two movable grooves 41, a prestressing roller 44 rotatably connected between the two movable seats 42, a motor 45 fixedly connected to one side of one of the movable seats 42, and the screw rod 43 is screwed in one of the movable seats 42, and the output shaft of the motor 45 is fixedly connected to one end of the prestressing roller 44.

[0037] The pre-stressing assembly also includes a roller body 49 rotatably connected between two movable seats 42, two edge pre-stressing portions 491 integrally formed on the outer surface of the roller body 49, a plurality of flanges 492 integrally formed on the outer surface of the roller body 49, a sprocket 46 and a sprocket 48 rotatably connected to one side of one of the movable seats 42, and a chain belt 47 connecting the sprocket 46 and the sprocket 48, wherein the sprocket 46 is fixedly connected to one end of the pre-stressing roller 44, and the sprocket 48 is fixedly connected to one end of the roller body 49.

[0038] By adopting the above technical solution, two motors 45 are used to drive two pre-pressing rollers 44 to rotate respectively. The two pre-pressing rollers 44 can pre-press the material before formal calendering, which can slightly reduce the thickness of the material and evenly distribute the pressure on the entire material, thereby avoiding excessive deformation caused by one-time calendering, especially avoiding excessive lateral expansion and stress concentration at the edge of the material. The rotation of the two pre-pressing rollers 44 can drive the two sprocket wheels 1 46 to rotate. The rotation of the two sprocket wheels 1 46 drives the two sprocket wheels 2 48 and the roller body 2 49 to rotate through the chain belt 47. When the roller body 2 49 rotates, the edge pre-pressing on the outer surface of the roller body 2 49 is Part 491 performs secondary pre-pressing on the edge of the pre-pressed material, which can effectively adjust the stress distribution at the edge. Since the edge is borne on a large lateral stress during the calendering process, the pre-pressing can release part of the stress concentration in advance, avoiding cracks or delamination at the edge due to excessive stress in subsequent calendering. The flange 492 on the outer surface of the roller body 49 can cause a depression on the surface of the material when pressed on the material. By pressing a depression on the surface, the material can have greater flexibility and ductility, and the stress concentration of the material in the depression area can be transferred to other areas, thereby alleviating the stress concentration inside the material and reducing the risk of cracks or deformation on the surface of the material.

[0041] The driving part includes a gear three 53 and two gear fours 54 rotatably connected to one side of one of the side panels 1, and a motor five 51 fixed to one side of a bracket one 21, and the two gear fours 54 are meshed with each other, one of the gear fours 54 is meshed with the gear three 53, and the two gear fours 54 are respectively fixed to one end of two rod bodies 571, the output shaft of the motor five 51 is fixed to the gear three 53, and a cylinder 52 is also fixed to one side of the bracket one 21, and the telescopic end of the cylinder 52 passes through the bracket one 21 and is fixed to a connecting plate 58, and one end of the two extension rods 574 passes through the rod body 571 and the gear four 54 to extend outward and is fixed to one side of the connecting plate 58.

[0042] By adopting the above technical scheme, the nozzle 56 can be externally connected to the liquid supply pipeline, and the nozzle 56 can spray the lubricant on the upper and lower surfaces of the material, thereby reducing the friction between the edge and the pressure roller, and avoiding local stress concentration caused by excessive friction between the material and the calendering roller 24. At the same time, the motor 51 drives the gear 3 53 and the two gears 4 54 to rotate, and the rotation of the two gears 4 54 respectively drives the two rod bodies 571 to rotate, and the rotation of the two rod bodies 571 respectively drives the two cleaning brushes 572 to rotate, and the two cleaning brushes 572 can brush the lubricant on the surface of the material, brush out the lubricant in the recesses on the upper surface of the material, and avoid excessive accumulation of lubricant in the recesses. At the same time, the extension and retraction of the cylinder 52 can drive the extension rod 574 to extend and retract, and the extension rod 574 can drive the cleaning brush 572 to move forward and backward outside the rod body 571, so that the cleaning brush 572 can move forward and backward while rotating, and the lubricant on the surface of the material can be brushed more evenly.

[0043] like Figure 1 and Figure 2 As shown, a grinding unit 6 is also connected between the two side plates 1, and the grinding unit 6 includes two movable grooves four 66 respectively opened in the two side plates 1, two slides 68 slidably connected in the movable grooves four 66, two grinding rollers two 70 respectively rotatably connected inside the two slides 68, two motors seven 69 respectively fixed to one side of the two slides 68, a screw rod four 67 rotatably connected in the movable groove four 66 and screwed in the two slides 68, two screw rods three 64 respectively screwed in the two side plates 1, two brackets three 61 respectively rotatably connected to one end of the two screw rods three 64, a grinding roller one 63 respectively rotatably connected inside the two brackets three 61, two motors six 62 respectively fixed to the upper ends of the two brackets three 61, and two groups of guide columns 65 respectively movably inserted in the two side plates 1 and respectively fixed to one side of the two brackets three 61, the output shaft of the motor seven 69 is fixed to the grinding roller two 70, and the output shaft of the motor six 62 is fixed to the grinding roller one 63.

[0044] By adopting the above technical solution, the two motors seven 69 can respectively drive the two grinding rollers two 70 to rotate, so as to grind the upper and lower surfaces of the material; the two motors six 62 can respectively drive the two grinding rollers one 63 to rotate, so as to grind the front and back sides of the material respectively. By finely grinding the upper and lower surfaces and edges of the material, fine burrs and rough surfaces are further removed, the smoothness of the edges is improved, the edges of the materials are ensured to be flat and smooth, the uneven stress distribution is reduced, and the stress concentration caused by defects such as irregularities, burrs and rough parts on the edges and surfaces is avoided.

[0045] Usage: When the material passes between the two calendering rollers 24, the motor 22 works to drive the two gears 23 to rotate, and the rotation of the two gears 23 drives the two calendering rollers 24 to rotate to calender the material. The motor 32 works to drive the two gears 33 to rotate, and the rotation of the two gears 33 can drive the two rollers 34 to rotate. The rotation direction of the two rollers 34 is opposite to the rotation direction of the two calendering rollers 24. When the two clamping parts 37 rotate to the vicinity of the material and are about to contact the material, the motor 381 works to drive the screw 383 to rotate, and the screw 383 rotates to drive the two pressure seats 384 to move toward each other, and the distance between the two pressure seats 384 becomes smaller and clamps the material to avoid The material moves, and at the same time, the motor 1 22 and the motor 4 45 also stop working, the calendering roller 24 and the pre-pressing roller 44 stop conveying and calendering the material, and the two clamping parts 37 clamp the material and pull the material to move in the opposite direction of the calendering roller 24, and apply longitudinal stress to pre-stretch the material before calendering. After stretching, the motor 1 22 and the motor 4 45 continue to work, and the two motors 45 respectively drive the two pre-pressing rollers 44 to rotate. The two pre-pressing rollers 44 can pre-press the material before formal calendering, which can slightly reduce the thickness of the material and evenly distribute the pressure on the entire material, thereby avoiding excessive deformation caused by one-time calendering. The rotation of the two pre-pressing rollers 44 can drive the two sprockets 1 46 to rotate. The two sprocket wheels 1 46 rotate through the chain belt 47 to drive the two sprocket wheels 2 48 and the roller body 2 49 to rotate. When the roller body 2 49 rotates, the edge pre-pressing part 491 on the outer surface of the roller body 2 49 performs secondary pre-pressing on the edge of the pre-pressed material, which can effectively adjust the stress distribution at the edge. When the flange 492 on the outer surface of the roller body 2 49 is pressed on the material, it can cause a depression on the surface of the material. By pressing a depression on the surface, the material can have greater flexibility and ductility. Before the material is calendered by the calendering roller 24, the nozzle 56 can be connected to an external liquid supply pipeline, and the nozzle 56 can spray lubricant on the upper and lower surfaces of the material to reduce the friction between the edge and the pressure roller, and avoid excessive friction between the material and the calendering roller 24. The local stress concentration caused by the operation of motor five 51 drives gear three 53 and two gear fours 54 to rotate. The rotation of the two gear fours 54 respectively drives the two rod bodies 571 to rotate. The rotation of the two rod bodies 571 respectively drives the two cleaning brushes 572 to rotate. The two cleaning brushes 572 can brush the lubricant on the surface of the material and brush out the lubricant in the recesses on the upper surface of the material to avoid excessive accumulation of lubricant in the recesses. At the same time, the extension and retraction of the cylinder 52 can drive the extension rod 574 to extend and retract. The extension rod 574 can drive the cleaning brush 572 to move forward and backward outside the rod body 571, so that the cleaning brush 572 can move forward and backward while rotating, and the lubricant on the surface of the material can be brushed more evenly.
