Description

Technical Field

[0001] The invention relates to the technical field of rolling equipment, and in particular to a reversible rolling equipment for nonferrous metal composite plates and strips. Background Art

[0002] A reversible rolling mill is a rolling machine that can complete forward and reverse rolling on the same device; the rolling process of the reversible rolling mill is as follows: the metal billet is fed into the rolling mill through a transmission mechanism, and the metal billet is pressed into a plate or strip of the required thickness through rolling by continuous rollers under high pressure, thereby achieving precision rolling of the metal plate or strip.

[0003] After searching, the patent document with the authorization announcement number CN115990613B discloses an aluminum plate rolling mechanism, including a moving mechanism for moving raw materials, a smelting device for melting the raw materials into aluminum liquid, an insulation device for insulating the aluminum liquid, a conveying device for conveying the aluminum liquid, a casting mechanism for solidifying the aluminum liquid into an aluminum plate, a first rolling device for cold-rolled aluminum plates, and a second rolling device for hot-rolled aluminum plates; the moving mechanism faces the inlet of the smelting device; the insulation device is connected to the middle position of the smelting device; the two ends of the conveying device are respectively connected to the outlet of the insulation device and the inlet of the casting mechanism; the second rolling device and the first rolling device are sequentially arranged at the outlet of the casting mechanism; the problem of how to ensure the rolling quality of the aluminum plate in the existing scheme is solved.

[0004] However, the above invention has the following shortcomings: the above aluminum plate rolling mechanism can be used for rolling metal strips with wider strip surfaces. If the pressure of the rollers used for rolling is unbalanced, the pressure on both sides of the main rollers is insufficient, the metal deformation trend will move to both sides. At this time, the wide strip will form wavy edges, and the wavy edges will be thicker (the rollers reciprocate in straight and curved shapes to make the wavy edges thicker).

The side pressure roller prevents the metal strip from continuing to deform to both sides, so that the wave edge is straightened. Even if part of the stress is concentrated in the middle, the subsequent vertical double-roller rolling mill will disperse the stress in the middle. Since the straightened wave thickness is qualified, the pressure on both sides of the pressure rollers of the subsequent vertical double-roller rolling mill is insufficient, and no wave edge will be generated.

The smoothing movement of the re-pressing roller is equivalent to reciprocating rolling of the metal strip, which can improve the accuracy of the metal strip.

[0024] Secondly, in the present invention, the driving assembly enables the movable frame to perform reciprocating linear movement, and the re-pressing roller performs reciprocating linear movement on the metal strip surface. During the smoothing movement of the re-pressing roller and the straightening of the wavy edges on both sides of the metal strip, the deformation stress will be further separated on the entire metal strip surface, and the wavy edge phenomenon will no longer occur. The smoothing movement and reciprocating linear movement of the re-pressing roller are equivalent to reciprocating rolling of the metal strip, which can improve the precision of the metal strip and does not require multiple rolling for precision adjustment.

[0040] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The present invention provides a non-ferrous metal composite plate and strip reversible rolling equipment through improvement. The technical solution of the present invention is:

[0042] like Figures 1 to 12 As shown, an embodiment of the present invention provides a non-ferrous metal composite plate and strip reversible rolling equipment, including a reference frame 2, and vertical twin-roller rolling machines 1 are installed on both sides of the reference frame 2. The vertical twin-roller rolling machine 1 is a prior art, and its specific structure and working principle are not described in detail here. Vertical twin-roller rolling machines are arranged on both sides of the reference frame 2, so that the entire rolling equipment has a symmetrical structure, and can be fed into rolling in the forward direction and can also be fed into rolling in the reverse direction, thereby realizing reversible rolling;

[0043] Combined with Figure 1 It can be seen that a moving frame 3 is arranged on the top of the reference frame 2, and the moving frame 3 is a metal bracket. A driving component 4 is arranged inside the reference frame 2 to enable the moving frame 3 to perform reciprocating linear movement;

[0044] Combined with Figure 2 It can be seen that a plurality of support rollers 11 are rotatably installed at the top of the reference frame 2, and the rolled metal strip is laid on the support rollers 11. The support rollers 11 are used to provide support force. Two sliding frames 12 are provided on the outer sliding sleeve of each support roller 11, and two sets of side pressure rollers 36 are rotatably installed at both ends of the sliding frame 12. The side pressure rollers 36 are used to limit the deformation direction of the metal strip, so that the metal strip cannot continue to deform to both sides.

[0045] The movable frame 3 is provided with an adjustment mechanism for adjusting the relative positions of the two sliding frames 12;

[0046] Combined with Figure 3 It can be seen that a fixed frame 13 is fixed to one side of each of the two sliding frames 12, and arc grooves 28 are provided at the top and bottom of the fixed frame 13. Here, the arc grooves 28 are supplemented. The center of the arc grooves 28 is located on the center line of each set of side pressure rollers 36;

[0047] Combined with Fig.10 It can be seen that the two arc grooves 28 are slidably provided with a second slider 35, and the second slider 35 can slide along the annular groove. The inner side of the arc groove 28 is provided with an annular groove coaxially arranged therewith, and one side of the second slider 35 is provided with a protrusion 38 of an integral structure therewith, and the protrusion 38 is slidably arranged in the annular groove. The protrusion 38 is arranged so that the second slider 35 can only slide in the arc groove 28;

[0048] Combined with Fig. 9 The first and second sliders 32 are connected to each other by a screw thread, and the first and second sliders 32 are connected to each other by a screw thread.

[0049] A toggle assembly is disposed in one of the sliding frames 12 to enable the two second sliding blocks 35 to slide synchronously in the same direction;

[0050] It can be known from the above connection relationship that: when the wave edge phenomenon occurs on one or both sides of the metal strip, the toggle assembly causes the two second sliders 35 to slide synchronously in the same direction, that is, the two second sliders 35 slide synchronously in the same direction in the circular arc groove 28 where each other is located, and the re-pressing roller 34 swings in a fan shape on the metal strip. Since the wave edge is thicker, the re-pressing roller 34 swings in a fan shape, which is equivalent to a smoothing movement, dispersing the deformation stress of the wave edge. The side pressure roller 36 prevents the metal strip from continuing to deform to both sides, so that the wave edge is straightened. Even if part of the stress is concentrated in the middle, the subsequent vertical twin-roller rolling mill 1 will disperse the stress in the middle. Since the straightened wave thickness is qualified, the pressure on both sides of the pressure rollers of the subsequent vertical twin-roller rolling mill is insufficient, and no wave edge will be generated.

[0051] The driving component 4 enables the movable frame 3 to move back and forth in a straight line, and the compound pressure roller 34 can move back and forth in a straight line on the surface of the metal strip. During the smoothing movement of the compound pressure roller 34 and the straightening of the wavy edges on both sides of the metal strip, the deformation stress will be further separated on the entire metal strip surface, and the wavy edge phenomenon will no longer occur. The smoothing movement and reciprocating linear movement of the compound pressure roller 34 are equivalent to reciprocating rolling of the metal strip, which can improve the accuracy of the metal strip and does not require multiple rolling for accuracy adjustment.

[0052] Specifically, combined with Figure 1-Figure 3 It can be seen that the driving assembly 4 includes two guide rails 5, which are fixed on the top of the reference frame 2, and a plurality of slides 16 are slidably sleeved on the guide rails 5, and the table tops of each slide 16 are fixed on the bottom of the mobile frame 3. The setting of the guide rails 5 and the slides 16 enables the mobile frame 3 to only perform reciprocating linear movement on the reference frame 2.

[0053] More specifically, Figure 1-Figure 3 It can be seen that the driving assembly 4 includes a large servo motor 7, a rotating plate 9 and a connecting rod 10. The casing of the large servo motor 7 is fixed in the reference frame 2, and the output shaft of the large servo motor 7 is fixed at the middle position of the rotating plate 9. The two ends of the connecting rod 10 are respectively rotatably mounted on one end of the rotating plate 9 and the middle position of the bottom of the moving frame 3. The large servo motor 7 rotates the rotating plate 9 through the output shaft, and the rotating plate 9 drives the moving frame 3 through the connecting rod 10. Due to the arrangement of the guide rail 5 and the slide 16, the moving frame 3 can only perform reciprocating linear movement on the reference frame 2, so the moving frame 3 performs reciprocating linear movement on the top of the reference frame 2.

[0054] More specifically, Figure 1-Figure 3 It can be seen that a center of gravity block 8 is fixed to the other end of the rotating plate 9. When the rotating plate 9 rotates, the center of gravity block 8 rotates accordingly. The end of the rotating plate 9 on which the center of gravity block 8 is installed has a large inertia, thereby reducing the output torsion of the large motor.

[0055] Specifically, combined with Figure 5 It can be seen that the adjustment mechanism includes two reference plates 37 and multiple guide rods 19. The bottoms of the two reference plates 37 are respectively fixed on both sides of the moving frame 3. The two ends of each guide rod 19 are respectively fixed on the two reference plates 37. The outer sliding sleeve of each guide rod 19 is provided with two connecting frames 18. The two connecting frames 18 are respectively fixed to the two sliding frames 12. The setting of the guide rods 19 and the connecting frames 18 enables the sliding frame 12 to only move linearly relative to the moving frame 3.

[0056] Specifically, combined with Figure 5-Figure 7It can be seen that the adjustment mechanism includes a double-threaded rod 21, a worm 24, a worm wheel 22, a rotating handle 25 and two support plates 23. Circular holes are provided on the outer sides of the two reference plates 37. The two ends of the worm 24 are rotatably installed in the circular holes respectively. The worm wheel 22 is coaxially fixed with the double-threaded rod 21, and the worm 24 is meshed with the worm wheel 22. The transmission form of the worm 24 and the worm wheel 22 is adopted because the worm 24 and the worm wheel 22 are self-locking. One end of the worm 24 is fixed to the handle. The handle is for the convenience of workers to apply rotational force to the worm 24. The two ends of the double-threaded rod 21 are respectively installed with nut sleeves compatible with them through threads. The two nut sleeves are respectively fixed to the two connecting frames 18. When the double-threaded rod 21 rotates, the double-threaded rod 21 causes the two connecting frames 18 to move synchronously and in opposite directions through the nuts on both ends, thereby adjusting the relative distance between the two connecting frames 18.

[0057] Specifically, combined with Figure 5-Figure 8 It can be seen that the toggle assembly includes an incomplete gear ring 29, a toothed plate 26, two connecting plates 20 and two square rods 14. The incomplete gear ring 29 is fixed to the second slider 35, and the incomplete gear ring 29 is coaxially arranged with the arc groove 28. One end of the two connecting plates 20 is respectively fixed to the two ends of the sliding frame 12, and the two square rods 14 are respectively slidably inserted into the two connecting plates 20. One end of the two square rods 14 is respectively fixed to the two ends of the toothed plate 26, and the toothed plate 26 is meshed with the incomplete gear ring 29. A spring 27 is sleeved on the outer side of the square rod 14, and the two ends of the spring 27 are respectively in contact with the connecting plate 20 and the toothed plate 26. Two contact plates 6 are fixed to the outer side of the reference frame 2, and the two square rods 14 are respectively close to the two contact plates 6. A driving plate is fixed to the bottom end of the second slider 35. 17, a straight notch 39 is provided at one end of the driving plate 17, and a cylindrical block 30 is slidably provided at the overlapped position of the two driving plates 17 with the straight notch 39, and both ends of the cylindrical block 30 are fixed with a limit plate 31; when the moving frame 3 moves on one side, the square rod 14 contacts the contact plate 6, and the square rod 14 is pushed toward the moving frame 3, and the toothed plate 26 on the square rod 14 moves the incomplete gear ring 29, and the incomplete gear ring 29 drives the second slider 35 to slide in the arc groove 28, and the driving plate 17 on the driven second slider 35 rotates accordingly, and the driving plate 17 drives another driving plate 17 through the cylinder, and at this time, the two driving plates 17 form an angle, and the other second slider 35 slides in the arc groove 28 where it is located, that is, the two second sliders 35 move synchronously in the same direction.

[0058] Specifically, a pulley 15 is rotatably mounted on one end of the square rod 14. The pulley 15 is arranged to change the contact form between the square rod 14 and the contact plate 6, that is, to change the friction into rolling friction, thereby reducing friction damage.

[0059] Working principle:

[0060] In the first step, one end of the metal to be rolled is fed into the vertical twin-roller rolling mill 1 on one end of the reference frame 2 for rolling, and a portion of the rolled metal is fed between the re-pressing roll 34 and the support roll 11, and then the vertical twin-roller rolling mill 1 is stopped;

[0061] The second step is to manually rotate the single threaded rod 33, and the single threaded rod 33 is driven by a thread, so that the first slider 32 moves down along the slide slot until the re-pressing roller 34 on the first slider 32 contacts the metal belt;

[0062] The third step is to start the vertical twin-roller rolling mill 1, and feed the metal strip into another vertical twin-roller rolling mill 1. After the feeding is completed, the large servo motor 7 is started;

[0063] The specific process of the third step is:

[0064] The large servo motor 7 rotates the rotating plate 9 through the output shaft, and the rotating plate 9 drives the moving frame 3 through the connecting rod 10. Due to the arrangement of the guide rail 5 and the slide 16, the moving frame 3 can only perform reciprocating linear movement on the reference frame 2. Therefore, when the moving frame 3 performs reciprocating linear movement on the top of the reference frame 2, that is, the re-pressing roller 34 performs reciprocating linear movement on the metal strip with the moving frame 3; when the moving frame 3 moves on one side, the square rod 14 contacts the contact plate 6, and the square rod 14 is pushed toward the moving frame 3, and the tooth plate 26 on the square rod 14 is not completely moved. The gear ring 29, the incomplete gear ring 29 drives the second slider 35 to slide in the circular arc groove 28, and the driving plate 17 on the driven second slider 35 rotates accordingly, and the driving plate 17 moves another driving plate 17 through the cylinder. At this time, the two driving plates 17 form an angle, and the other second slider 35 slides in the circular arc groove 28 where it is located, that is, the two second sliders 35 move synchronously in the same direction, that is, the two second sliders 35 slide synchronously in the circular arc groove 28 where each other is located, and the re-pressing roller 34 swings in a fan shape on the metal belt;

[0065] Since the wave edge is thicker, the re-pressing roller 34 swings in a fan shape, which is equivalent to a smoothing motion to disperse the deformation stress of the wave edge. The side pressure roller 36 prevents the metal strip from continuing to deform to both sides, so that the wave edge is straightened. Even if part of the stress is concentrated in the middle, the subsequent vertical double-roller rolling mill 1 will disperse the stress in the middle. Since the straightened wave thickness is qualified, the pressure on both sides of the pressure rollers of the subsequent vertical double-roller rolling mill is insufficient, and no wave edge will be generated; the driving component 4 causes the movable frame 3 to move back and forth in a straight line, and the re-pressing roller 34 can move back and forth in a straight line on the metal strip surface. During the smoothing motion of the re-pressing roller 34 and the straightening of the wave edges on both sides of the metal strip, the deformation stress will be further separated on the entire metal strip surface, and the wave edge phenomenon will no longer occur. The smoothing motion and reciprocating linear motion of the re-pressing roller 34 are equivalent to reciprocating rolling of the metal strip, which can improve the precision of the metal strip and does not require multiple rolling for precision adjustment.

[0066] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
