[0037] Embodiment 1

[0038] Ginseng Figure 1 and Figure 2 As shown, this embodiment discloses a specific implementation method of a production device (hereinafter referred to as "production device") for improving the strength of high-strength and high-conductivity copper-aluminum composites.

[0039] A production device for improving the strength of high-strength and high-conductivity copper-aluminum composites, Figure 1 and Figure 2As shown, it includes a gantry support 1, a first rolling roller 2 and a second rolling roller 3; the gantry support 1 includes a first vertical support 11, a first horizontal support 12, a second vertical support 13 and a second horizontal support 14, a first hinge point 15 is set between the first vertical support 11 and the first horizontal support 12, a second hinge point 16 is set between the second vertical support 13 and the second horizontal support 14, the first vertical support 11, the first horizontal support 12, the second vertical support 13, the second horizontal support 14, the first hinge point 15 and the second hinge point 16 constitute an open gantry support 1, the first horizontal support 12 has a rotation angle range of 0°-90° around the first hinge point 15 as the center, and the second horizontal support 14 has a rotation angle range of 0°-90° around the second hinge point 16 as the center The range is 0°-90°; a first bearing seat 4 is arranged on the first vertical support 11, a second bearing seat 5 is arranged on the second vertical support 13, and the first rolling roller 2 is installed on the first bearing seat 4 and the second bearing seat 5 through a first bearing 21; a first vertical slide rail 6 and a third bearing seat 7 are arranged on the first vertical support 11, and the third bearing seat 7 is lifted and lowered along the first vertical slide rail 6, a second vertical slide rail 8 and a fourth bearing seat 9 are arranged on the second vertical support 13, and the fourth bearing seat 9 is lifted and lowered along the second vertical slide rail 8; the second rolling roller 3 is installed on the third bearing seat 7 and the fourth bearing seat 9 through a second bearing 31; a first booster assembly 71 is arranged below the third bearing seat 7, and a second booster assembly 91 is arranged below the fourth bearing seat 9.

[0040] Specifically, the following defects exist in traditional rolling production equipment: (1) A closed gantry support is used, and a horizontal track needs to be set up for the installation of the rolling roller. The rolling roller is installed through the horizontal track, and there are mechanical damages such as collision, wear, and scratches between the upper and lower rolling rollers, which can easily cause wear on the surface of the rolling roller, affecting the flatness and parallelism of the surface of the rolling roller. The closed gantry support occupies a large area; (2) A large roller diameter (1300mm-1700mm) rolling roller is used to ensure the rolling force, but the contact area between the large roller diameter rolling roller and the copper-aluminum composite material is large, which has problems such as high energy consumption, high cost, and long production cycle. There are also defects such as insufficient rolling pressure and energy consumption. In order to overcome the above-mentioned defects, the present embodiment adopts an open gantry support 1, and simultaneously adopts a first booster assembly 71 and a second booster assembly 91; on the one hand, the first horizontal support 12 and the second horizontal support 14 of the open gantry support 1 can be opened. After opening, the second rolling roller 3 and the first rolling roller 2 can be successively suspended and installed from the top of the opened gantry support 1 from top to bottom, avoiding the traditional practice of horizontally pushing the rolling rollers, and also avoiding the mutual wear and scratches between the rolling rollers caused by horizontally pushing the rolling rollers. Mechanical damage such as, thereby ensuring the flatness and parallelism of the surfaces of the second rolling roller and the first rolling roller; on the other hand, the first booster assembly 71 and the second booster assembly 72 act on the third bearing seat 7 and the fourth bearing seat 9 respectively, which can significantly increase the rolling force between the second rolling roller 3 and the first rolling roller 2. Thereby, the peel strength between the copper-aluminum composite materials is effectively increased; thirdly, in the traditional rolling process, in order to increase the rolling force, a rolling roller with a large roller diameter (1300mm-1700mm) is required, which has the defects of high energy consumption and a large contact area between the rolling roller and the copper-aluminum composite material, resulting in insufficient pressure of the rolling roller on the copper-aluminum composite material. In this embodiment, the first boosting component 71 and the second boosting component 91 are used. Even if the second rolling roller 3 and the first rolling roller 2 with a small roller diameter (930mm-990mm) are used, not only can the rolling roller with a large roller diameter (1300mm-1700mm) be replaced, but also because the contact area between the second rolling roller 3 and the first rolling roller 2 of the embodiment and the copper-aluminum composite material is reduced, the rolling pressure is increased, which can effectively ensure the composite strength of the copper-aluminum composite material.

[0041] The working principle of the open gantry support 1 is as follows, see Figure 1 and Figure 2In normal circumstances, the gantry support 1 is in a closed state, the angle between the first horizontal support 12 and the first vertical support 11 is 90°, and the angle between the second horizontal support 14 and the first vertical support 13 is 90°; when the first rolling roller 2 and the third rolling roller 3 need to be replaced, the first horizontal support 12 and the second horizontal support 14 are opened, so that the angle between the first horizontal support 12 and the first vertical support 11 is 0°, and the angle between the second horizontal support 14 and the second vertical support 13 is 0°, so that the first horizontal support 12 and the second horizontal support 14 are in a straight line. In the open state, the second rolling roller 3 is suspended from top to bottom from the space between the first horizontal support 12 and the second horizontal support 14 to the third bearing seat 7 and the fourth bearing seat 9; the first rolling roller 2 is suspended from top to bottom from the space between the first horizontal support 12 and the second horizontal support 14 to the first bearing seat 4 and the second bearing seat 5; by suspending the second rolling roller 3 and the first rolling roller 2 from top to bottom, the friction between the second rolling roller 3 and the first rolling roller 2 is avoided, so that the surfaces of the second rolling roller 3 and the first rolling roller 2 remain smooth, which helps to improve the efficiency of roller changing.

[0042] The working principle of the second rolling roller 3 pressurization is as follows, see Figure 1 and Figure 2 The first boosting assembly 71 uses a first boosting pump, which applies a vertical upward force ( Figure 1 The force F (in the direction of the arrow shown by F) is increased in the middle of the third bearing seat 7, and the direction of the force F passes through the axis of the second bearing 31. The force F causes the third bearing seat 7 to rise and fall slightly along the first vertical slide rail 6; the second boosting assembly 91 adopts a second boosting pump, and the second boosting pump increases the vertical upward force in the middle of the fourth bearing seat 9, and causes the fourth bearing seat 9 to rise and fall slightly along the second vertical slide rail 8; the maximum boosting pressure of the first boosting pump and the second boosting pump are both 40MPa; when the boosting pressure of the first boosting pump and the second boosting pump is 0, the maximum rolling force of the first rolling roller 2 and the second rolling roller 3 is 2000 tons; the boosting pressure of the first boosting pump and the second boosting pump is When the pressure is 40MPa, the maximum rolling force of the first rolling roller 2 and the second rolling roller 3 is 4000 tons, which is twice as much as that without pressurization. The first booster pump and the second booster pump simultaneously apply vertical upward pressure to the third bearing seat 7 and the fourth bearing seat 9. Under the condition of the same roller spacing between the first rolling roller 2 and the second rolling roller 3, this embodiment can greatly increase the rolling force between the rollers through the first booster pump and the second booster pump. When the first rolling roller 2 and the second rolling roller 3 with a small roller diameter (930mm-990mm) are used, the first rolling roller 2 and the second rolling roller 3 exert a greater pressure on the copper-aluminum composite material, which is more conducive to improving the interfacial bonding strength of the copper-aluminum composite material.

[0043] Embodiment 2

[0044] Ginseng Figure 3 As shown, this embodiment discloses a specific implementation method of a production process for improving the strength of high-strength and high-conductivity copper-aluminum composites.

[0045] A production process for improving the strength of high-strength and high-conductivity copper-aluminum composites, Figure 3 As shown, the following steps are included:

[0046] S1: Select a first rolling roller and a second rolling roller with a roller diameter of 930mm-990mm; specifically, select a first rolling roller and a second rolling roller with a small roller diameter, and install the second rolling roller and the first rolling roller from top to bottom above an open gantry support 1 of a production device for improving the strength of high-strength and high-conductivity copper-aluminum composite according to Example 1.

[0047] S2: adjusting the gap between the first rolling roller and the second rolling roller; specifically, adjusting the gap between the first rolling roller and the second rolling roller according to the thickness of the copper-aluminum composite material to be rolled.

[0048] S3: Start rolling, and synchronously start the first boosting assembly and the second boosting assembly at both ends of the second rolling roller. Specifically, the maximum boost pressure of the first boost pump and the second boost pump is 40MPa; when the boost pressure of the first boost pump and the second boost pump is 0, the maximum rolling force of the first rolling roller 2 and the second rolling roller 3 is 2000 tons; when the boost pressure of the first boost pump and the second boost pump is 40MPa, the maximum rolling force of the first rolling roller 2 and the second rolling roller 3 is 4000 tons, which is doubled compared with the non-boosted state; the first boost pump and the second boost pump simultaneously apply vertical upward pressure to the third bearing seat 7 and the fourth bearing seat 9. Under the condition of the same roller spacing between the first rolling roller 2 and the second rolling roller 3, this embodiment can greatly improve the rolling force between the rollers through the first boost pump and the second boost pump. When the first rolling roller 2 and the second rolling roller 3 with a small roller diameter (930mm-990mm) are used, the first rolling roller 2 and the second rolling roller 3 have a greater pressure on the copper-aluminum composite material, which is more conducive to improving the interface bonding strength of the copper-aluminum composite material.
