[0026] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0027] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0028] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects or their order.

[0029] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0030] The cladding material of the copper-aluminum alloy flat bar is copper (T2 copper, which is an industrial grade of pure copper, indicating a purity of 99.90% or higher, belonging to cathode remelted copper), and the core is aluminum alloy (Al1070 aluminum (industrial pure aluminum) or 8030 aluminum alloy). This copper-aluminum alloy flat bar has a density of 4250 kg / m³, an elastic modulus of 81 GPa, a yield strength of 250 MPa, a tensile strength of 350 MPa, and a Poisson's ratio of 0.32, exhibiting strong ductility.

[0031] Copper-aluminum alloy flat bars are available in two sizes: 40mm (width) × 32mm (thickness) with a 4mm edge radius, and 30mm (width) × 30mm (thickness) with a 4mm edge radius. These flat bars are typically packaged in coils to form copper-aluminum alloy flat bar rolls (which include a spool and the flat bars wound on it). The length of the flat bars in these rolls can reach up to 90m, and the weight can reach up to 490kg.

[0032] In related technologies, copper-aluminum alloy flat bars are prone to orientation shifts after entering the rolling mill module, causing them to enter the rolling mill body at a deviated angle for rolling. This reduces rolling accuracy and increases rolling difficulty.

[0033] To address the aforementioned issues, this disclosure provides a rolling apparatus for copper-aluminum alloy flat bars, comprising a feeding device (not shown in the figure), a rolling device, and a discharging device (not shown in the figure) arranged in sequence, wherein the rolling device includes multiple rolling modules arranged in sequence.

[0034] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 6The rolling module includes a housing, a rolling mill body 300 located inside the housing, a guide device, and a mounting device 400. The guide device is mounted on the panel of the housing via the mounting device 400. The guide device is used to guide and support the copper-aluminum alloy flat bars entering and exiting the housing, ensuring smooth and precise entry of the flat bars into the rolling mill body 300 for rolling, and smoothly exiting the flat bars from the rolling mill body 300 and the housing for the next process. In this example, the mounting device 400 includes a feeding mounting structure 16 and a discharging mounting structure 20. The guide device includes a feeding unit 100 and a discharging unit 200. The feeding unit 100 is mounted on the panel of the housing (not shown in the figure) via the feeding mounting structure 16, and the discharging unit 200 is mounted on the panel of the housing via the discharging mounting structure 20.

[0035] In one embodiment of this disclosure, the feeding unit 100 is located on the feeding side of the rolling mill body 300, and the discharging unit 200 is located on the discharging side of the rolling mill body 300. This not only limits the conveying of the copper-aluminum alloy flat bars entering the box and the rolling mill body 300, ensuring the accuracy and stability of rolling, but also avoids the generation of defective products due to the deviation of the copper-aluminum alloy flat bars. Furthermore, after rolling is completed, the copper-aluminum alloy flat bars can continue to be conveyed with limited positioning, allowing them to enter the next process with high precision.

[0036] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 5 The discharge unit 200 includes a discharge shell 25, which has a discharge channel 26 inside. In this example, the discharge channel 26 is divided into two sections: a second feeding section and a second passing section. The second feeding section is positioned facing the rolling mill body 300 and has a flared structure, with its large-diameter end facing the rolling mill body 300. The second passing section can be rectangular. In other words, the dimension of the second feeding section away from the second passing section is larger than the dimension of the second feeding section closer to the second passing section, and the dimension of the second feeding section closer to the second passing section is equal to the dimension of the second passing section. The dimension of the second feeding section away from the second passing section (the dimension of the large-diameter end) is larger than the distance between the two rolling rolls in the rolling mill body 300. This allows the rolled copper-aluminum alloy flat bar to smoothly enter the discharge unit 200 for guided output.

[0037] In one embodiment of this disclosure, the size of the rectangular opening can be adapted to the size of the copper-aluminum alloy flat bar output after rolling by the corresponding rolling mill body 300. Of course, in other embodiments, the size of the rectangular opening can be slightly larger than the size of the copper-aluminum alloy flat bar output after rolling, so that the guide device of the same specification can be used for rolling dies with different rolling sequences; at the same time, it can also be used for rolling copper-aluminum alloy flat bars of different sizes, thus reducing costs.

[0038] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 5 , Figure 6 and Figure 7 The discharge shell 25 is mounted on the discharge mounting structure 20. In one example, the discharge mounting structure 20 includes a second mounting plate 21, a retainer 22, a first fixing structure 23, and a second fixing structure 24.

[0039] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 6 and Figure 7 The retainer 22 has a first fixing frame 221 and a first trapezoidal protrusion 222 connected to the outside of the first fixing frame 221 (in one example, the first fixing frame 221 and the first trapezoidal protrusion 222 are integrally formed). The first fixing frame 221 is provided with a through hole, the width of which is adapted to the width of the discharge shell 25, and the height of which is greater than the height of the discharge shell 25. One end of the discharge shell 25 passes through the through hole, so that the middle part of the discharge shell 25 is placed in the through hole. A first fixing structure 23 (in one example, the first fixing structure 23 can be a fixing bolt; in other examples, the first fixing structure 23 can adopt other structures not shown) passes through the first fixing frame 221 and abuts against the discharge shell 25 to fix the discharge shell 25.

[0040] Optional, see Figure 7 The second fixing structure 24 includes a mounting base 241, a locking plate 242, and a locking bolt 243. The mounting base 241 is fixed to the second mounting plate 21 by the mounting bolt. The mounting base 241 has a groove that matches one end of the first trapezoidal protrusion 222. The locking plate 242 has a groove that matches the other end of the first trapezoidal protrusion 222. The first trapezoidal protrusion 222 of the retainer 22 is located in the groove on the mounting base 241. The groove of the locking plate 242 overlaps the first trapezoidal protrusion 222, and the locking plate 242 and the mounting base 241 are fixed by the locking bolt 243, thereby limiting and fixing the first trapezoidal protrusion 222 of the retainer 22 between the mounting base 241 and the locking plate 242, thus fixing the discharge shell 25.

[0041] Of course, in other embodiments, the first fixing structure 23 and the second fixing structure 24 may also adopt other structures not shown, as long as they can satisfy the fixing of the discharge unit 200.

[0042] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The feeding unit 100 includes a first structure 1, a second structure 3 and a third structure 4.

[0043] Optional, see Figure 1 , Figure 6 and Figure 8 The first structure 1 has an internal feeding channel 2 for copper-aluminum alloy flat bars to pass through. The feeding channel 2 can be divided into a first feeding section and a first conveying section. The first feeding section is located away from the rolling mill body 300. The first feeding section has a flared structure, and its large-diameter end is located away from the rolling mill body 300. The first conveying section can be rectangular. In other words, the dimension of the side of the first feeding section away from the first conveying section is larger than the dimension of the side of the first feeding section close to the first conveying section, and the dimension of the side of the first feeding section close to the first conveying section is equal to the dimension of the first conveying section. The dimension of the side of the first feeding section away from the first conveying section (the dimension of the large-diameter end) is not smaller than the dimension of the box body inlet. In this way, the copper-aluminum alloy flat bars after entering the box body can smoothly enter the feeding unit 100.

[0044] Optionally, at the first material passage section, the first structure 1 has through-holes on both opposite sides, so that the outside is connected to the feed channel 2 at the through-holes.

[0045] The second structure 3 is fitted outside the first structure 1 and is connected to the first structure 1 by multiple fixing bolts. The second structure 3 does not overlap with the through gap. In other words, the second structure 3 will not block the through gap.

[0046] There are two third structures 4, both of which are set on the second structure 3, and the two third structures 4 are set one-to-one with the two through gaps.

[0047] Optionally, the third structure 4 has a mounting shell 5, see [link / reference]. Figure 3 and Figure 4 The second structure 3 has a first rotating shaft 8 on the outside of each of the two corresponding third structures 4. One end of the mounting shell 5 is fitted onto the first rotating shaft 8, and the mounting shell 5 can rotate around the first rotating shaft 8. The axis of the first rotating shaft 8 is perpendicular to the extension direction of the feed channel 2, and the other end of the mounting shell 5 is a free end. At least one elastic element 7 is provided between the mounting shell 5 and the outer wall of the second structure 3. It can be understood that one end of the elastic element 7 is connected to the mounting shell 5, and the other end is connected to the outer wall of the second structure 3. When the mounting shell 5 rotates around the first rotating shaft 8, the elastic element 7 provides elastic force so that the mounting shell 5 can return to its original position under the action of the elastic force. In this structure, the third structure 4 has a first position and a second position; in the first position, the distance between the two third structures 4 is the smallest, and in the second position, the distance between the two third structures 4 is greater than the distance between the two third structures 4 in the first position.

[0048] In one example, the elastic element 7 can be a spring. In another example, the elastic element 7 can be any other structure with elastic properties.

[0049] In one example, the number of elastic elements 7 is set according to requirements.

[0050] In one embodiment of this disclosure, the mounting housing 5 is provided with a receiving groove for accommodating the elastic member 7. In the first position, the elastic member 7 is located in the receiving groove. In this way, the volume of the feeding unit 100 can be further reduced, and the cost and weight can be reduced.

[0051] See in this example. Figure 1 and Figure 3 The mounting housing 5 has at least one roller mounting area near the through-hole. When there are multiple roller mounting areas, they are arranged sequentially along the extension direction of the feed channel 2. Each roller mounting area has a rotating shaft seat 9. The first end of the rotating shaft seat 9 passes through the mounting housing 5 and is located outside the mounting housing 5. The first end of the rotating shaft seat 9 is fixed to the mounting housing 5 by a locking structure 11. The rotating shaft seat 9 can rotate relative to the mounting housing 5 (in other words, the rotating shaft seat 9 can rotate after the locking structure 11 is released). A second rotating shaft 10 is mounted on the rotating shaft seat 9, and the axis of the second rotating shaft 10 is not coaxial with the axis of the rotating shaft seat 9 (in other words, the second rotating shaft 10 is eccentrically mounted on the rotating shaft seat 9). A roller 6 is sleeved and mounted on the second rotating shaft 10, and the roller 6 can rotate relative to the second rotating shaft 10. The axis of the roller 6 is perpendicular to the extension direction of the feed channel 2.

[0052] In one example, the locking structure 11 can be an end cap nut, through which the pivot seat 9 can be fastened to the mounting housing 5. In another example, the locking structure 11 can be other structures not shown.

[0053] See in this example. Figure 1 At least a portion of the roller 6 passes through the through-hole and is located within the feed channel 2. The rollers 6 in the two third structures 4 are arranged opposite each other, and the sidewalls of the two opposite rollers 6 are used for rolling contact with the copper-aluminum alloy flat bar. In other words, each roller 6 in the two opposite third structures 4 is arranged in a one-to-one correspondence, thereby forming a rolling channel between each roller 6 in the two third structures 4. When the copper-aluminum alloy flat bar passes through, the two opposite rollers 6 can realize the rolling conveying of the copper-aluminum alloy flat bar.

[0054] In one embodiment of this disclosure, the number of roller mounting areas can be one, two, three, etc., depending on the requirements. In this example, the number of roller mounting areas is two, which can effectively achieve the rolling conveying of copper-aluminum alloy flat bars without excessively increasing the size of the feeding unit 100.

[0055] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2The second structure 3 is also provided with two limiting structures 12 corresponding to the two third structures 4. The limiting structures 12 are located on the movement path of the mounting shell 5 and are used to limit the opening size of the third structures 4. In this example, the limiting structure 12 can be a connecting shaft. In other examples, the limiting structure 12 can be other structures not shown, such as a fixing block.

[0056] In this embodiment, under the action of the elastic element 7, the mounting shell 5 has a first position and a second position. The elastic force of the elastic element 7 in the second position is greater than that in the first position. In the first position, the two third structures 4 are symmetrically arranged relative to the feeding channel 2. A portion of the roller 6 passes through the through-hole and is located within the feeding channel 2. The copper-aluminum alloy flat rod passes between the two opposing rollers 6. Furthermore, in the first position, the distance between the two opposing rollers 6 is less than the size of the copper-aluminum alloy flat rod. Thus, when the copper-aluminum alloy flat rod enters between the two corresponding rollers 6, the mounting shell 5 opens, realizing the rolling conveying of the copper-aluminum alloy flat rod.

[0057] The feeding unit 100 is used as follows: First, based on the dimensions of the copper-aluminum alloy flat bar, rotate the rotating shaft seat 9. With the mounting shell 5 not under force, adjust the distance between the two relatively set rollers 6. After adjustment, lock the position of the rotating shaft seat 9 through the locking structure 11. The distance between the two relatively set rollers 6 is less than the dimensions of the copper-aluminum alloy flat bar.

[0058] After the copper-aluminum alloy flat bar enters the feeding channel 2, it is fed between the two rollers 6. Under the continuous feeding action of the copper-aluminum alloy flat bar, the two mounting shells 5 will open under force, and the distance between the two rollers 6 will increase to adapt to the size of the copper-aluminum alloy flat bar. Through the close contact between the copper-aluminum alloy flat bar and the two rollers 6, and under the position of continuous feeding of the copper-aluminum alloy flat bar, the rollers 6 can realize the rolling feeding of the copper-aluminum alloy flat bar, reduce the friction between the feeding unit 100 and the copper-aluminum alloy flat bar, improve the feeding efficiency, and reduce the wear of the copper-aluminum alloy flat bar.

[0059] In one embodiment of this disclosure, the mounting housing 5 has a protrusion 13 between any two adjacent roller mounting areas. The protrusion 13 has a cooling passage connecting the outside of the mounting housing 5 with the corresponding roller mounting area. An inlet connector 14 is provided at the inlet of the cooling passage for connecting to the coolant input pipe of the cooling device. In this way, coolant can be injected into the cooling device to cool the roller 6.

[0060] In one embodiment of this disclosure, the roller 6 is lubricated with dry oil.

[0061] In one embodiment of this disclosure, the mounting shell 5 has a groove on its exterior, and the first rotating shaft 8, the limiting structure 12, and a portion of the mounting shell 5 are located within the groove, thereby reducing the size of the entire feeding unit 100 and lowering costs.

[0062] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 3 The second structure 3 has a second fixing frame 25 and a second trapezoidal protrusion 15 disposed on one side of the second fixing frame 25, wherein the small-diameter end of the second trapezoidal protrusion 15 is connected to the second fixing frame 25. The second fixing frame 25 and the second trapezoidal protrusion 15 can be integrally formed.

[0063] In this embodiment, see Figure 6 , Figure 7 and Figure 8 The feeding installation structure 16 includes a first mounting plate 17, and a first adjustment structure 18 and a second adjustment structure 19 disposed on the first mounting plate 17. The first mounting plate 17 is disposed on the panel of the box body. The first adjustment structure 18 is used to adjust the position of the feeding unit 100 along a first direction, and the second adjustment structure 19 is used to adjust the position of the feeding unit 100 along a second direction. In one example, see Figure 3 and Figure 6 The first adjustment structure 18 includes a limiting plate 181 and a fixing member 182. The limiting plate 181 has a groove that matches the second trapezoidal protrusion 15 (e.g., the base angle of the second trapezoidal protrusion 15 is 60 degrees). The second trapezoidal protrusion 15 of the second structure 3 is engaged in the matching groove to limit and fix the position of the second structure 3. The fixing member 182 connects the limiting plate 181 and the first mounting plate 17 to fix the limiting plate 181. In this example, the limiting plate 181 may include a first plate, a second plate, and a third plate. The first plate and the third plate are both fixed to the second plate by bolts, and a groove matching the second trapezoidal protrusion 15 is formed between the second plate and the third plate.

[0064] In one example, the second adjustment structure 19 includes a fixed post 191 and an adjustment member 192. The fixed post 191 is disposed on the first mounting plate 17 and has a threaded hole. The adjustment member 192 can be an adjustment screw. The adjustment screw is threaded through the fixed post 191 and connected to the outside of the second structure 3. The tightness of the feed unit 100 can be adjusted by screwing the adjustment screw in and out.

[0065] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
