Description

Technical Field

[0001] The present invention relates to the technical field related to non-ferrous metal processing, and specifically to a multi-roll efficient non-ferrous metal precision rolling mill. Background Art

[0002] Non-ferrous metals, in the narrow sense, are also known as non-ferrous metals, which are the general term for all metals other than iron, manganese, and chromium. In the broad sense, non-ferrous metals also include non-ferrous alloys. A non-ferrous alloy is an alloy composed of a non-ferrous metal as the matrix (usually more than 50%) and one or several other elements added. When rolling non-ferrous metals, a rolling mill can be used to roll non-ferrous metals, and after rolling, the non-ferrous metal plate is pulled and collected by a clamping device.

[0003] However, the existing metal rolling mills cannot well adjust the distance between the two rolling rolls. To solve the above problems, reference can be made to a metal rolling mill disclosed in the prior art (Chinese Patent with Application No. CN202320836671.6 and Application Date: April 15, 2023). After adjusting the pressure roll to the specified position, rotate the connecting plate. Since the connecting shaft is fixed on the connecting plate, the positioning roll rotates around the connecting shaft. After moving the positioning roll to the specified position, turn the nut. After the nut is squeezed against the connecting plate, the connecting plate is fixed. The metal strip bypasses the positioning roll and then passes between the pressure roll and the support roll, realizing the movement of the metal strip perpendicular to the connection line of the axes of the pressure roll and the support roll, so as to meet the requirement of rolling the metal strip into a specified thickness; and reference can also be made to a metal rolling mill disclosed in the prior art (Chinese Patent with Application No. CN202410679696.9 and Application Date: May 29, 2024). When the correction plate clamps the metal sheet (i.e., when moving downward), the pressing device drives the connecting piece to move first to the blanking side and then downward, so as to be able to fit at the end of the metal sheet, facilitating cleaning starting from the end of the metal sheet, thus avoiding the residue of large particle impurities at the end of the metal sheet, which may cause scratches and defects during the rolling process; at the same time, when the metal sheet contacts the cleaning roll during rotation, due to the inclined design of the roll, the impurities will be gradually pushed to both sides of the cleaning roll; thus, it can both clamp the metal sheet and guide the metal sheet to the rolling mechanism, and can also clean the large particle impurities on the upper surface while clamping the metal sheet, and can also push the impurities to both sides of the cleaning roll for collection during cleaning; and reference can also be made to a non-ferrous metal rolling mill disclosed in the prior art (Chinese Patent with Application No. CN202121735380.5 and Application Date: July 28, 2021). The rolling mill can drive the rotating shaft to rotate through the first motor arranged, thereby driving two groups of cutting wheels to cut the metal sheet, cutting off the irregular parts at the edge of the metal sheet, and at the same time limiting the size specification of the finished metal sheet.

[0004] Although the various devices mentioned above show a certain degree of convenience in adjusting the distance between the two calender rolls and provide some assistance for actual production operations, when deeply analyzing their comprehensive performance in an industrial scenario, it is not difficult to notice that they still have short - comings that cannot be ignored. Take the rolling operation of non - ferrous metals as an example. After the rolling process is completed, a large amount of heat energy accumulated inside the material needs to be dissipated urgently because subsequent processes often have strict requirements for the material temperature. Otherwise, it will directly affect the product quality and processing accuracy. Unfortunately, these existing devices precisely expose obvious defects in the cooling link. They lack an effective and efficient cooling mechanism, resulting in the non - ferrous metal plate being unable to disperse heat in a timely manner when it has completed rolling and is about to enter the next process, thereby hindering the coherence and smoothness of the entire production chain, slowing down the production rhythm, increasing production costs, and being difficult to meet the growing refined and efficient demands of the current non - ferrous metal processing industry.

[0005] Therefore, we propose a multi - roll high - efficiency precision rolling unit for non - ferrous metals to solve the problems raised above. Summary of the Invention

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 11 , the present invention provides the following technical solution: A multi-roll efficient non-ferrous metal precision rolling unit.

[0023] Embodiment 1: To solve the problem that after rolling non-ferrous metals in the current market, a large amount of heat will be generated. At this time, the non-ferrous metal plate still needs to be cooled during the subsequent processes, and the prior art cannot perform cooling well. Reference can be made to Appendix Figure 1 - Appendix Figure 6 , Appendix Figure 9 and Appendix Figure 10 , which includes a workbench 1 located on the horizontal ground. A preheating module 2 is installed at the upper left end of the workbench 1. The non-ferrous metal plate extends into the preheating module 2, and the other end of the non-ferrous metal plate extends into the rolling frame 3. The bottom of the rolling frame 3 is fixed on the top of the workbench 1; A first delivery pipe 13 is also connected to one side of the air delivery member 9. One end of the first delivery pipe 13 is arranged on one side of the limiting mechanism. The setting of the limiting mechanism can adjust the two sets of edge trimming components 18 at the right side of the workbench 1, and a multi-position cooling mechanism is also arranged at the upper end of the limiting mechanism. The multi-position cooling mechanism realizes the cooling treatment of the non-ferrous metal plate in different directions; The multi-position cooling mechanism includes a lower air outlet 21 connected to the outer end of a second delivery pipe 20 made of a hose. The outer side of the lower air outlet 21 is slidably arranged inside the placement groove 101. One end of the second delivery pipe 20 is threadedly connected to the outer end of the reciprocating lead screw 22. The two ends of the reciprocating lead screw 22 are rotatably arranged inside the placement groove 101, and one end of the reciprocating lead screw 22 extends out of the outer side of the workbench 1 and is fixedly connected to the connecting gear 23; The outer end of the connecting gear 23 is meshed and connected to the outer end of the rotating gear 11. The lower air outlet 21 forms a reciprocating sliding structure with the inside of the placement groove 101 through the reciprocating lead screw 22. The height of the lower air outlet 21 is lower than the depth of the placement groove 101.

[0024] After the non-ferrous metal is rolled, the rolled non-ferrous metal moves out from the right side position of the rolling frame 3. At this time, when the driving motor 6 drives the mating roller 7 to rotate, it can also drive the sector gear 8 to rotate. As a result, the rotating gear 11 engaged with the sector gear 8 at one side position of the sector gear 8 will also rotate. Then, the center position of the rotating gear 11 drives the upper air jet 10 to rotate at one side position of the workbench 1, so that the upper air jet 10 can rotate above the rolled non-ferrous metal plate. In addition, by starting the operation of the air delivery component 9, the air delivery component 9 delivers air into the upper air jet 10. The gas cools the upper part of the non-ferrous metal plate through the rotatably arranged upper air jet 10. After the sector gear 8 and the rotating gear 11 are no longer engaged, the rotating gear 11 drives the upper air jet 10 to rotate back through the torsion spring 12, so as to cool the upper part of the non-ferrous metal plate in multiple directions. In addition, the air delivery component 9 can deliver air into the first delivery pipe 13. At this time, the solenoid valve on one side of the first delivery pipe 13 needs to be closed. The gas is delivered into the rotating part 14 through the first delivery pipe 13, and after being resisted, the gas will be released through the pressure nozzle 1403. At this time, the gas is delivered into the second delivery pipe 20 through the pressure nozzle 1403, and the gas inside the second delivery pipe 20 cools the lower part of the non-ferrous metal plate through the lower air jet 21. In addition, during the rotation of the rotating gear 11, the outer end of the rotating gear 11 can drive the engaged connecting gear 23 to rotate, so that the connecting gear 23 drives the reciprocating lead screw 22 to rotate, resulting in the position adjustment of the thread-connected lower air jet 21 inside the placement groove 101. At this time, through the water spraying and cooling treatment on the upper and lower sides, the multi-directional cooling treatment of the non-ferrous metal plate can be further accelerated.

[0025] Embodiment 2: To facilitate the subsequent edge trimming of the rolled metal plate, reference can be made to the attached Figure 1 - attached Figure 3 、attached Figure 5 、attached Figure 7 - attached Figure 9 and attached Figure 11, there are two sets of calendering mechanisms inside the calendering frame 3. The calendering mechanisms are arranged to calender the outer side of the non-ferrous metal plate. A gas delivery component 9 is fixedly installed at the top of the calendering frame 3, and the output end of the gas delivery component 9 is connected to the upper end of the upper air jet 10 through a pipeline; the calendering mechanism includes a hydraulic push rod 4 fixed at the upper position inside the calendering frame 3. The output end of the hydraulic push rod 4 is rotatably arranged at the shaft end position of the calendering roll 5. A matching roll 7 is also rotatably arranged below the calendering roll 5. The output end of the driving motor 6 is fixed at the outer end of the matching roll 7. A sector gear 8 is fixed at the shaft end position of the right matching roll 7 extending outside the calendering frame 3; the calendering roll 5 forms a sliding structure between the inside of the calendering frame 3 through the hydraulic push rod 4, and the size of the matching roll 7 is set to be the same as that of the calendering roll 5; a placement groove 101 is provided in the middle of the surface of the workbench 1, and two waste discharge ports 102 are provided at the right end position of the workbench 1. A rotating gear 11 is fixed at the outer end position of the upper air jet 10, and the outer side of the rotating gear 11 is meshed and connected to the outer side of the sector gear 8. One end of the upper air jet 10 away from the rotating gear 11 is connected to one side of the workbench 1 through a torsion spring 12; the limiting mechanism includes a rotating member 14 connected to the outer end of the first conveying pipe 13 made of a hard pipe. The top of the first conveying pipe 13 is a square hard pipe. The lower edge on both sides of the rotating member 14 is rotatably connected to a movable rod 15. The other end of the movable rod 15 is rotatably arranged at one end of a support rod 16. The other end of the support rod 16 is fixed to one side of the mounting plate 17. A trimming component 18 is also fixed inside the mounting plate 17. The upper center position of the rotating member 14 is rotatably arranged at the bottom position of the second conveying pipe 20; the inside of the trimming component 18 includes a motor and a cutting blade. The output end of the motor rotates and is fixed to the center position of the cutting blade inside the mounting plate 17. The outer shell of the motor is fixed to the outside of the mounting plate 17 through bolts. A guide block 19 is also fixed to one side of the mounting plate 17. The protruding position of the guide block 19 is slidably arranged inside the waste discharge port 102; limiting rods 1904 are fixed to the inner sides of the two guide blocks 19. The outer ends of the limiting rods 1904 extend into the inside of the receiving sleeve 1901, and the outer ends of the limiting rods 1904 are connected to the inner wall of the receiving sleeve 1901 through a compression spring 1905. The middle rear position of the receiving sleeve 1901 communicates with one end of the matching conveying pipe 1902. The other end of the matching conveying pipe 1902 is connected to the first conveying pipe 13 through a solenoid valve. An elastic abutting block 1903 is also hermetically slidably arranged inside the receiving sleeve 1901. The guide block 19 is transparent and a scale is provided on the surface of the guide block 19;The interior of the rotating member 14 includes a sealing spiral sleeve 1401 slidably disposed on the outer side of the top of the first delivery pipe 13. The sealing spiral sleeve 1401 is vertically slidably connected to the square hard pipe at the top of the first delivery pipe 13 by radial engagement and axial fitting. The outer side of the sealing spiral sleeve 1401 is spirally connected to the inside of the spiral groove 1402, and the outer side of the spiral groove 1402 is opened inside the rotating member 14. A pressure nozzle 1403 is provided at the top of the sealing spiral sleeve 1401; the elastic force of the pressure nozzle 1403 is greater than the frictional force of the spiral between the sealing spiral sleeve 1401 and the spiral groove 1402, and the rotating member 14 forms a rotating structure through the spiral groove 1402 and the inside of the sealing spiral sleeve 1401. The outer side of the pressure nozzle 1403 corresponds to the position inside the second delivery pipe 20.;

[0026] By starting the driving motor 6, the output end of the driving motor 6 drives the cooperating roller 7 to rotate, and the non-ferrous metal plate is placed between the cooperating roller 7 and the rolling roller 5. Subsequently, by starting the hydraulic push rod 4, the output end of the hydraulic push rod 4 drives the rolling roller 5 to move, so as to perform rolling treatment on the non-ferrous metal plate. In addition, before the gas delivery member 9 delivers gas to the inside of the first delivery pipe 13, by opening the solenoid valve on one side of the cooperating delivery pipe 1902, the gas can be delivered to the inside of the flow guiding block 19 at this time, so that the sealing and sliding receiving sleeve 1901 can move relatively. At this time, one end of the receiving sleeve 1901 will move to the designated position. Subsequently, by closing the solenoid valve, the sealing spiral sleeve 1401 inside the rotating member 14 can be moved, resulting in the spiral thread on the outer side of the sealing spiral sleeve 1401 sliding in the spiral groove 1402. Since the pitch of the sealing spiral sleeve 1401 and the spiral groove 1402 is relatively large, when the sealing spiral sleeve 1401 moves vertically, the rotating member 14 can be driven to rotate in position through the spiral groove 1402. At this time, the rotating member 14 drives the movable rod 15 to rotate during the rotation process, so that the movable rod 15 can drive the support rod 16 and the mounting plate 17 to move. At this time, one side of the mounting plate 17 will also drive the edge cutting assembly 18 and the gas delivery member 9 to move. The gas delivery member 9 cooperates through the protruding position, and at this time the edge cutting assembly 18 will move stably. At this time, the limiting rod 1904 fixed on one side of the flow guiding block 19 will move inside the receiving sleeve 1901. One end of the limiting rod 1904 abuts against one side of the compression spring 1905. Since the elastic force of the compression spring 1905 is greater than the elastic force of the pressure nozzle 1403, the pressure nozzle 1403 can be stably delivered at this time, and the cutting blade is driven by the output end of the motor to perform edge cutting treatment on the rolled non-ferrous metal plate. The waste material will be guided and moved through the flow guiding block 19 with an arc-shaped bottom below, so that the waste material moves to the lower position of the workbench 1, facilitating the later collection work. Through the above settings, it is convenient to collect and process the rolled non-ferrous metal plate.

[0027] In addition, when collecting and processing non-ferrous metal plates, when the clamped device is used to pick up the trimmed non-ferrous metal plates, due to the inability to effectively position and the phenomenon of deviation when pulling the trimmed non-ferrous metal plates for blanking, at this time, the overall trimmed non-ferrous metal plates are set obliquely. One side of the non-ferrous metal plate is very likely to fit with one side of the diversion block 19 due to the deviation phenomenon, which may cause the non-ferrous metal plate to bend. To avoid this phenomenon, please refer to the appendix Figure 11 , first stop the operation of the gas delivery part 9. Since the inside of the receiving sleeve 1901 is filled with gas, at this time, the inside of the receiving sleeve 1901 and the inner side of the elastic abutting block 1903 are in a state of pressure balance. And when the sliced non-ferrous metal plate is extruded inside the diversion block 19, at this time, the diversion block 19 will extrude the non-ferrous metal plate, and then the diversion block 19 can be adjusted left and right as a whole through the setting of the limiting rod 1904, thereby avoiding damage during the process of pulling the non-ferrous metal plate.
