Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, and specifically relates to positioning, tensioning, leveling or guiding strip materials, and more particularly to a perforated copper busbar winding system and a working method. Background Art

[0002] In the related art, a clamping roller and a fixed roller are required during the winding process of the perforated copper busbar. The mechanical pressure applied by the clamping roller is changed by controlling the distance between the clamping roller and the fixed roller, thereby providing friction, thereby achieving stable conveying and winding of the strip. However, the clamping roller is a solid roller as a whole, which applies the same mechanical pressure to the entire conveyed strip. However, since there are through holes parallel to the length direction of the perforated copper busbar inside the busbar, the through holes will cause the effective cross-sectional area of ​​the corresponding area to be reduced, thereby causing its transverse tensile strength to drop significantly. If the same mechanical pressure as the solid area is used, plastic deformation is likely to occur, resulting in the collapse of the through holes.

[0003] Therefore, due to the technical problem that applying the same mechanical pressure to the entire conveyed perforated copper busbar will cause plastic deformation of the through holes in the perforated copper busbar, resulting in the through holes being crushed, it is necessary to design a perforated copper busbar winding system and working method.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0065] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0066] The perforated copper busbar is a preferred alternative to the outer wall of the existing server radiator casing. It is based on the better thermal conductivity of copper metal compared to aluminum metal. The holes opened in the copper busbar form an airflow channel, thereby efficiently transferring the heat generated by the server to the air. In the related art, the continuous production of such perforated copper busbars is achieved by heating the copper rod - extruding with an extruder - cooling down - winding and rewinding. For this type of unwinding and rewinding method, that is, the strip is not released through a reel but is wound and rewound on a straight strip. A clamping roller and a fixed roller are required. By controlling the distance between the clamping roller and the fixed roller, the mechanical pressure applied by the clamping roller is changed to provide friction, thereby achieving stable conveying and winding of the strip.

[0067] However, the inventors found that in the related art, the clamping roller is a solid roller as a whole, which applies the same mechanical pressure to the entire conveyed strip. However, since there are through holes parallel to the length direction inside the perforated copper busbar, the through holes will cause the effective cross-sectional area of ​​the corresponding area to be reduced, thereby causing its transverse tensile strength to drop significantly. If the same mechanical pressure as that of the solid area is used, plastic deformation is likely to occur, causing the through holes to be crushed.

[0068] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

There is a solid area 32 between adjacent through holes 31, and the area between the edge of the perforated copper busbar 3 in the width direction and the corresponding nearest through hole 31 is also a solid area 32.

[0073] In this embodiment, during the winding process of the perforated copper busbar 3, the perforated copper busbar 3 needs to be clamped by the clamping roller 11 and the supporting roller 15 before winding, and as the winding thickness increases, that is, the coil diameter corresponding to the perforated copper busbar 3 that has been wound on the winding roller 21 increases, as the coil diameter increases, the clamping force decreases due to the factor of taper tension control.

[0074] In this embodiment, the rotating ring 111 contacts the surface position corresponding to the solid area 32 of the perforated copper busbar 3, so as to clamp the surface corresponding to the solid area 32 of the perforated copper busbar 3 during the winding process; the notch 112 corresponds to the surface position corresponding to the through hole 31 of the perforated copper busbar 3, so as to clamp the surface corresponding to the through hole 31 of the perforated copper busbar 3 through the air pressure of the air outlet 113 during the winding process, so as to prevent the surface corresponding to the through hole 31 of the perforated copper busbar 3 from being subjected to the same clamping force as the surface corresponding to the solid area 32, thereby preventing the through hole 31 from collapsing under pressure.

[0075] In this embodiment, the rotating ring 111 rotates during the winding process of the perforated copper busbar 3 .

[0081] like Figure 4 As shown, in an optional embodiment, the method for adjusting the pressure of the gas ejected from the gas outlet 113 according to the clamping force is: the control module obtains the ratio of the effective cross-sectional area of ​​the perforated copper busbar 3:

[0085] ;

[0086] in, P is the pressure of the gas ejected from the gas outlet 113, in units of Pa ; S is the nozzle cross-sectional area, in units of m 2 The control module is configured to control the gas output of the gas source to adjust the pressure of the gas ejected from the gas outlet 113.

[0087] In this embodiment, the pressure of the gas ejected from the gas outlet 113 is adjusted according to the clamping force applied by the clamping roller 11 on the perforated copper busbar 3 under the winding diameter of the perforated copper busbar 3 currently wound by the winding device 2, so that the pressure of the gas ejected from the gas outlet 113 on the surface corresponding to the through hole 31 in the perforated copper busbar 3 is smaller than the clamping force applied by the clamping roller 11 on the perforated copper busbar 3 under the winding diameter of the perforated copper busbar 3 currently wound by the winding device 2, thereby preventing the through hole 31 from collapsing under pressure.
