Description

Technical Field

[0001] The present invention relates to the technical field of copper strip winding, and in particular to a copper strip blank winding system. Background Art

[0002] Copper strip refers to the initial or semi-finished form of copper material for further processing into final products. It is made by rolling ingots into strip materials of a certain thickness through hot rolling or cold rolling processes. In order to produce finished copper strips that meet industrial needs, large coils of heavy and long strips need to be subsequently processed. For this thicker copper strip, because the material is more easily deformed in a hot state, a larger thinning rate can be achieved, which can release internal stress and reduce the possibility of deformation or cracking in subsequent processing. Therefore, hot rolling is more commonly used. After the final hot rolling is completed, the copper strip needs to be coiled. The existing technology usually uses a dedicated strip coiler to complete the coiling.

[0003] For example, the Chinese patent application number CN 201820827885.6 discloses a copper strip blank winder, comprising a frame, a supporting portion for guiding the copper strip blank into the winder is provided at the bottom of the frame, and a winding portion for bending the copper strip blank upward is provided at a position adjacent to the supporting portion on the frame. The copper strip blank is bent upward by the winding portion, and after bending, the copper strip blank moves along an arc-shaped trajectory. When the copper strip blank is deflected, a centering adjustment device can be used to limit the two sides of the copper strip blank to keep it neat, and finally the copper strip blank enters the winding portion for winding. However, in actual use, since the copper strip blank is relatively soft, there is a tendency for uneven extension in the width direction under the action of the coiling tension, that is, the tension in the middle is large and the extension is large; while the edges are constrained by the centering adjustment device and have less extension. In addition, in terms of traditional thermal management cooling, the use of the current blowing method will also cause this uneven extension to be accumulated and amplified, and then manifested on the coil as the inner ring strip becoming narrower in width or wavy in width direction. This not only affects the neatness of the coil, but also seriously affects the stability and yield rate of the subsequent uncoiling and leveling processes. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a copper strip blank winding system to solve the technical problem that in the actual use of the existing technology, due to the relatively soft copper strip blank, there is a tendency of uneven extension in the width direction under the action of the winding tension, that is, the tension in the middle is large and the extension is large; while the edges are constrained by the centering adjustment device and the extension is small. In addition, in terms of traditional thermal management cooling, the use of the current blowing method will also cause this uneven extension to be accumulated and amplified, and then manifested as the inner ring strip becoming narrower in width or wavy in width direction on the strip coil.

[0019] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] The first aspect of the present invention provides a copper strip blank winding system, such as Figure 1-9 As shown, it includes a frame 1 and rollers 2 provided on the frame 1 for supporting the copper strip blank coil. The top of the frame 1 is provided with a limit plate 4 through a hydraulic cylinder 3 arranged opposite to it. The middle part of the frame 1 is provided with a pre-deformed upper guide roller 5 that contacts the surface of the copper strip blank. The winding system also includes: The lower pre-deformation guide roller 6 is liftable and arranged in the frame 1. There is a gap for pressing the embryo between the upper pre-deformation guide roller 5 and the lower pre-deformation guide roller 6. The roller surfaces of the upper pre-deformation guide roller 5 and the lower pre-deformation guide roller 6 are concave from both sides to the middle. The lower pre-deformation guide roller 6 has a cavity structure and micro-channels are arranged in the axial direction. A vortex tube 7 is provided in the pre-deformation lower guide roller 6, and a cold air flow outlet of the vortex tube 7 is directed toward the micro-channel of the pre-deformation lower guide roller 6; The aerosol cooling boxes 8 are located on both sides of the gap extending toward the pressed embryo, and the hot air flow outlet of the vortex tube 7 is connected to the air inlet end of the aerosol cooling box 8; An upper winding roller 9 and a lower winding roller 10 are provided on the other side of the frame 1; A driving unit for driving the upper winding roller 9 and the lower winding roller 10 to rotate; The transmission part is used to drive the aerosol cooling box 8 to swing back and forth.

[0022] In this embodiment, when in use, the copper strip blank is introduced into the pre-deformation area formed by the pre-deformation upper guide roller 5 and the pre-deformation lower guide roller 6 in the frame 1, and the pre-deformation lower guide roller 6 is driven to rise. The gap between the pre-deformation upper guide roller 5 and the pre-deformation lower guide roller 6 forces the edge of the copper strip blank to produce additional extension, and the upper winding roller 9 and the lower winding roller 10 further press and reel the stretched copper strip blank. After the hydraulic cylinder 3 drives the limit plate 4 to slide toward each other, the reeled copper strip blank is reeled and supported on the roller 2 under the limiting action of the edge of the limit plate 4, and finally the copper strip blank coil is transferred to the storage area by the gantry crane arranged above. Specifically, the upper winding roller 9 and the lower winding roller 10 are first driven to rotate by the driving part, and at the same time, the pre-deformation upper guide roller 5 is driven to rotate by the transmission part. The roller surfaces of the pre-deformation upper guide roller 5 and the pre-deformation lower guide roller 6 are both concave from both sides to the middle, which can make the copper strip blank tend to be extended toward the middle, so that the copper strip blank forms a trend effect of being thick in the middle and thin at the edges. Then, the extended copper strip blank is further thinned and reeled by the upper winding roller 9 and the lower winding roller 10, which can compensate for the excessive extension of the middle part caused by uneven tension. At the same time, in the process of the transmission part driving the aerosol cooling box 8 to swing back and forth, since the pre-deformed lower guide roller 6 is a cavity structure and has micro-channels arranged axially, and the cold air flow outlet of the vortex tube 7 is directed to the micro-channels of the pre-deformed lower guide roller 6, the vortex tube 7 can generate a low-temperature cold airflow to form a low-temperature environment inside the cavity of the pre-deformed lower guide roller 6, and spray it to the lower surface of the copper strip before winding through the micro-channels of the pre-deformed lower guide roller 6, and focus on contact cooling on both sides of the pre-deformed lower guide roller 6 where heat generation is more serious; The hot air flow outlet of the vortex tube 7 is connected to the air inlet end of the aerosol cooling box 8, and is mixed with the atomized water to form aerosol. As the aerosol cooling box 8 swings back and forth to change the cooling area, the aerosol can be dynamically sprayed to the two states of the strip before and after the blank extension gap. Under the combined cooling of the guide roller 6 roller surface contact cooling under pre-deformation and the dynamic cooling of the aerosol, the problem of uneven extension being accumulated and amplified due to excessive temperature difference in the traditional blowing cooling method is avoided, the accumulation process of uneven extension is interrupted, and the winding quality of the strip is guaranteed.

[0023] In this embodiment, if Figure 2 As shown, a guide roller 11 for guiding the feeding of the copper strip blank is provided at the front end of the frame 1. The guide roller 11 corresponds to the extension gap of the pressed blank in the feeding direction of the copper strip blank. After adjusting the installation height of the guide roller 11 at the front end of the frame 1, the copper strip blank is placed on its roller surface and guided into the pre-deformation area formed by the pre-deformation upper guide roller 5 and the pre-deformation lower guide roller 6, so as to avoid excessive resistance of the copper strip blank made of softer material during the winding and insertion process.

[0024] In this embodiment, if Figure 1 、 Figure 3 As shown, the driving unit includes: A mounting frame 12 provided on the frame 1; A drive motor 13 is mounted on the mounting frame 12, and a synchronous wheel 14 is provided at the output end of the drive motor 13; A second synchronous wheel 15 is coaxially mounted on one side of the lower winding roller 10, and the second synchronous wheel 15 is connected to the first synchronous wheel 14 via a synchronous belt; A driving gear 16 is coaxially mounted on the other side of the lower winding roller 10; A driven gear 17 is coaxially mounted on the side end of the upper winding roller 9, and the driven gear 17 is meshed with the driving gear 16; Specifically, the output end of the drive motor 13 drives the synchronous wheel 14 to rotate, and the upper roller of the lower winding roller 10 is driven to rotate in the outer conveying direction of the winding system through the synchronous belt and the synchronous wheel 2 15. Under the meshing action of the driving gear 16 and the driven gear 17, the lower roller of the upper winding roller 9 at an angle above can be rotated in the outer conveying direction of the winding system, thereby thinning the copper strip blank and automatically winding it obliquely upward.

[0025] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 As shown, there are two rollers 2, one of which is rotatably mounted on the mounting frame 12, and a driven gear 2 18 is coaxially mounted on the other side of the roller 2. The driven gear 2 18 is engaged with the driven gear 1 17. The rotation of the driven gear 17 drives the roller 2 to rotate through the driven gear 2 18, and the rotation direction is consistent with the rotation direction of the lower winding roller 10, so that the copper strip blank is placed between the two rollers 2 after winding.

[0026] In this embodiment, if Figure 4 、 Figure 5 As shown, the transmission unit includes: A synchronous wheel 19 provided at the side end of the upper winding roller 9; A synchronous wheel 20 is provided at the side end of the pre-deformation upper guide roller 5, and the synchronous wheel 20 is connected to the synchronous wheel 3 19 through a synchronous belt; Rotate the swing fork 21 provided at the side end of the pre-deformation lower guide roller 6, and the aerosol cooling box 8 is provided on both sides of the swing fork 21; A toggle plate 22 is eccentrically mounted on the side end of the pre-deformed upper guide roller 5, and the outer edge of the toggle plate 22 cooperates with the inner wall of the swing fork 21; Specifically, the pre-deformation upper guide roller 5 drives the toggle disk 22 to rotate, and since the swing fork 21 is rotatably arranged at the side end of the pre-deformation lower guide roller 6, the outer edge of the toggle disk 22 toggles the inner wall of the swing fork 21, so that the swing fork 21 can swing back and forth around the connection with the pre-deformation lower guide roller 6, thereby realizing the synchronous reciprocating swing of the aerosol cooling box 8.

[0027] In this embodiment, if Figure 5 、 Figure 6 As shown, a pawl 23 is fixedly installed on the side end of the swing fork 21, and a ratchet 24 is fixedly installed on the side end of the pre-deformation lower guide roller 6. The pawl 23 cooperates with the ratchet 24, and the reciprocating swing of the swing fork 21 drives the pawl 23 at the side end to move synchronously. Since the pawl 23 cooperates with the ratchet 24, under the action of the pawl 23, the ratchet 24 can be driven to rotate continuously and intermittently, thereby driving the vortex tube 7 to rotate synchronously and intermittently in the pre-deformation lower guide roller 6, thereby ensuring the cooling effect of contact cooling.

[0028] In this embodiment, if Figure 4 、 Figure 5 As shown, the middle part of the outer edge of the toggle plate 22 is a raised structure, and the middle part of the inner wall of the swing fork 21 is a groove structure. The raised structure is limited and slidable in the groove structure. During the lifting and lowering process of the pre-deformed lower guide roller 6, the raised structure in the middle part of the outer edge of the toggle plate 22 can maintain sliding cooperation with the groove structure in the middle part of the inner wall of the swing fork 21, thereby ensuring the operational stability of the system.

[0029] In this embodiment, if Figure 5 As shown, a strip-shaped opening 25 is provided in the middle of the toggle disk 22, and the roller shaft of the pre-deformed upper guide roller 5 is adjustably installed in the strip-shaped opening 25 by means of bolts. By adjusting the installation position of the roller shaft of the pre-deformed upper guide roller 5 in the strip-shaped opening 25, the eccentric distance between the toggle disk 22 and the pre-deformed upper guide roller 5 can be adjusted, thereby adjusting the toggle path of the toggle disk 22 on the swing fork 21, and then adjusting the reciprocating swing degree of the swing fork 21, so as to effectively control the cooling range and cooling duration of the copper strip blank.

[0030] In this embodiment, if Figure 8 As shown, sliding seats 26 are provided on both sides of the pre-deformation lower guide roller 6. The sliding seats 26 are slidably arranged in the frame 1. A hydraulic cylinder 27 is installed in the frame 1. The sliding seats 26 are arranged on the output end of the hydraulic cylinder 27. By driving the hydraulic cylinder 27 so that its output end drives the sliding seat 26 to slide in the frame 1, the pre-deformation lower guide roller 6 is synchronously driven to perform oblique lifting and lowering movements.

[0031] In this embodiment, if Figure 9 As shown, semi-hidden rollers 28 are staggered on the surface of the limit plate 4, and a guide column 29 is provided on the back of the limit plate 4. The guide column 29 is slidably arranged on the top of the frame 1. The hydraulic cylinder 3 drives the limit plate 4 to stretch under the guidance of the guide column 29, so that the copper strip blank in the winding stage can complete the limited winding under the guidance of the roller 28, thereby ensuring the flatness of the side end of the copper strip blank coil.
