[0002] In the preparation of the copper-based composite material, when the copper wire is used in an oxygen environment, a challenge is that the surface of the copper-based material will be oxidized over time, which eventually causes corrosion. It is found in research that graphene can be used as a candidate material for an anti-corrosion coating of the surface of the copper-based material. The use of graphene can protect the copper wire from deep penetrating oxidation, greatly reducing the oxidation rate of the copper, and becoming the first process in the preparation process of the copper-based composite material. The excellent performance of the copper-based composite material can enhance the use performance of the copper-based material.

[0050] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0051] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0052] Please see Figures 1 to 14 As shown, this invention provides a high-performance copper-based composite material preparation equipment using a drawing, rolling, and ultrasonic friction consolidation composite process. The equipment includes a copper-based material composite equipment body 1, which comprises a support platform 10 and a sealing cover 11. A cavity 101 is formed at the center of the top of the support platform 10. A high-carbon steel rolling mold 12 is provided at the top of the cavity 101. The high-carbon steel rolling mold 12 has a rolling groove 121 for placing copper wires 50. Fixing mechanisms 13 for fixing the ends of the copper wires 50 are provided at both ends of the high-carbon steel rolling mold 12. The sealing cover 11, made of tempered transparent glass, prevents leakage of inert gas and avoids inhalation and injury. A tail gas port is provided at the rear end of the sealing cover 11 for connecting to a tail gas absorption device to remove excess tail gas from the copper-based material composite equipment body 1 before opening the sealing cover 11. The bottom of the rolling groove 121 is arc-shaped on both sides to facilitate the removal of the consolidated copper matrix.

[0053] In this invention, the bottom of the high carbon steel rolling die 12 is also provided with two guide holes 122 that match the size of the short shaft 41. An arc-shaped part 123 is fixed to the bottom of the high carbon steel rolling die 12 located in front of each guide hole 122. The bottom of the high carbon steel rolling die 12 is placed into the cavity 101, and the high carbon steel rolling die 12 is fixed on the short shaft 41 through the guide holes 122.

[0054] Specifically, the fixing mechanism 13 includes a base plate 130 fixed to the top of the support platform 10. An opening groove 1301 is provided in the middle of the top of the base plate 130. A top plate 131 is provided at the upper end of the base plate 130. A locking block 1310 is integrally formed on the base plate 130. The locking block 1310 is engaged with the opening groove 1301. Two tightening members 132 are provided on the outer side of the top plate 131. The end of each tightening member 132 passes through the top plate 131 and is threaded to the outer wall of the base plate 130. In the preparation stage of the high-performance copper-based composite material preparation, the ends of several copper wires 50 are placed into the opening groove 1301, and the locking block 1310 on the inner side of the top plate 131 is locked into the opening groove 1301. The base plate 130 and the top plate 131 are fixed by using the tightening members 132, which can limit the two ends of the copper wires 50 and tighten the copper wires 50 to facilitate the subsequent rolling operation.

[0055] Furthermore, the left and right ends of the support platform 10 are provided with a fixing mechanism 2 for fixing the copper wire 50. The fixing mechanism 2 includes a pressure roller 22 and an ultrasonic roller 23 set on the upper end of the roller pressing groove 121. The fixing mechanism 2 includes a mounting box 20 fixed on the left and right sides of the support platform 10 and a straight rack 21 set inside each mounting box 20. The upper ends of the left and right walls of the mounting box 20 are provided with sliding grooves 201. The sliding grooves 201 limit the first connecting shaft 220 and the second connecting shaft 24, so that the ends of the first connecting shaft 220 and the ends of the second connecting shaft 24 roll in the opening groove 1301. The pressure roller 22 is used to perform preliminary fixing of the copper wire 50.

[0056] Furthermore, a first connecting shaft 220 is rotatably connected to the pressure roller 22. First gears 222 are sleeved on the rods at both ends of the first connecting shaft 220. A first motor 221 is coaxially connected to the right end of the first connecting shaft 220. Each first gear 222 meshes with its corresponding rack 21. The first motor 221 is connected to a power source via a wire, driving the first connecting shaft 220 to rotate. The first connecting shaft 220 drives the first gears 222 to roll on the rack 21, controlling the pressure roller 22 to move back and forth above the roller pressing groove 121. Simultaneously with the rotation of the first connecting shaft 220, the pressure roller 22 rotates, ensuring it is pressed against the copper wire 50 in the roller pressing groove 121. After the pressing, the pressure roller 22 rests at the front end of the high-carbon steel roller pressing mold 12, without affecting the subsequent ultrasonic roller 23 pressing operation.

[0057] It is worth noting that the ultrasonic roller 23 contains a vibrator 230 and a rotating shaft 231 rotatably connected to the vibrator 230. Both ends of the rotating shaft 231 have second connecting shafts 24, which are rotatably connected to each other. The first end of each second connecting shaft 24 has a flange 241. The left and right outer ends of the ultrasonic roller 23 are fixedly connected to the two flanges 241 by bolts, forming an integral structure between the two second connecting shafts 24 and the ultrasonic roller 23. The end of each second connecting shaft 24 is fitted with a second gear 242, which engages with a spur gear on the same side. The second motor 243 is coaxially fixed at the end of the second connecting shaft 24 located on the right side of the ultrasonic roller 23. The second motor 243 is connected to the power supply through a wire. The second motor 243 drives the second connecting shaft 24 on the same side to rotate, and drives the ultrasonic roller 23 to rotate. At the same time, it drives the vibrator 230 inside the ultrasonic roller 23 to generate high-frequency vibration. The high-frequency vibration generated by the vibrator 230 is transmitted to the outer wall of the ultrasonic roller 23. The ultrasonic roller 23 is used to roll the copper wire 50. Moreover, the pressure surface size of the ultrasonic roller 23 is the same as that of the pressure wheel 22 to ensure that the contact area with the copper wire 50 is consistent.

[0058] Specifically, an inert gas tank 3 is provided on the top of the sealing cover 11, and a vent pipe 31 is provided at the rear end of the inert gas tank 3. The end of the vent pipe 31 passes through the top of the sealing cover 11 and extends to the rear side of the roller pressing groove 121, so as to allow inert gas to be introduced into the rolling area during the ultrasonic roller 23 process. Several mounting seats 30 are provided on the inert gas tank 3, and the inert gas tank 3 is fixed to the top of the sealing cover 11 by several mounting seats 30. An inflation hole is provided at the front end of the inert gas tank 3 to facilitate inflation of the inert gas tank 3. A control valve is provided at the rear end of the inert gas tank 3, and the outlet of the control valve is fixed to the beginning of the vent pipe 31 to improve the gas flow capacity and facilitate timely corrosion protection of the solidified copper base.

[0059] Finally, a lifting mechanism 4 is provided inside the cavity 101. The height of the high carbon steel roller pressing mold 12 can be adjusted by the lifting mechanism 4, which facilitates the adjustment of the distance between the pressure roller 22, the ultrasonic roller 23 and the roller pressing groove 121, and can control the degree of pressing of the copper wire 50.

[0060] It is worth noting that the lifting mechanism 4 includes a lead screw 40 rotatably connected to the front and rear walls of the cavity 101, a short shaft 41 sleeved on the bottom of the high-carbon steel rolling die 12, and an adjusting plate 42 fixed to the head end of the lead screw 40. Two first bevel gears 401 are keyed and fixed on the body of the lead screw 40, and second bevel gears 410 are keyed to the bottom of the two short shafts 41. Each second bevel gear 410 has a convex round part 411 on its top surface that cooperates with the arc-shaped part 123. By rotating the adjusting plate 42, the adjusting plate 42 drives the lead screw 40 to rotate, and the first bevel gears 401... The screw 40 meshes with the second bevel gear 410, and drives the two first bevel gears 401 on its shaft to rotate, which in turn drives the second bevel gear 410 to rotate synchronously. When the second bevel gear 410 rotates, the convex round part 411 at the top of it abuts against the arc-shaped part 123 at the bottom of the high carbon steel rolling die 12. Since the bottom of the high carbon steel rolling die 12 is sleeved on two short shafts 41, when the convex round part 411 abuts against the arc-shaped part 123, it drives the high carbon steel rolling die 12 to move up and down along the cavity 101, thereby realizing the up and down adjustment of the high carbon steel rolling die 12.

[0061] This invention provides a process for preparing a copper-based composite material by drawing, rolling, and ultrasonic friction bonding, comprising the following steps:

[0062] I. Preparation stage for the preparation of high-performance copper-based composite materials:

[0063] S1. First, introduce the copper wire 5 on the winding machine into the wire polishing machine, polish the copper wire 5 using the wire polishing machine, and cut the copper wire 5 into several copper wires 50 of equal length and diameter between 0.05-0.5mm.

[0064] S2. Prepare a graphene aqueous solution in the graphene immersion tank 6, and put the cut copper wires 50 into the trough 60 in the graphene immersion tank 6 and immerse them for 25 minutes.

[0065] S3. After soaking, remove the trough 60 from the graphene soaking tank 6, take out the copper wire 50 with graphene aqueous solution on the surface, tie it to the partition in the drying oven 7, and use the hot air blower 8 to dry the graphene aqueous solution on the surface of the copper wire 50. After drying, place the copper wire 50 side by side in the rolling groove 121 of the high carbon steel rolling die 12, and use the fixing mechanism 13 to tighten and fix the two ends of the copper wire 50.

[0066] II. Consolidation Stage in the Preparation of High-Performance Copper-Based Composite Materials:

[0067] S4. First, close the sealing cover 11, then start the first motor 221, so that the first motor 221 drives the first connecting shaft 220 to rotate. The first connecting shaft 220 drives the pressure wheel 22 to rotate, and at the same time drives the first gears 222 at both ends to rotate, so that the first gears 222 roll back and forth on the rack 21. The pressure wheel 22 is used to initially press the copper wires 50 in the roller pressing groove 121. Through the pressing of the copper wires 50 by the pressure wheel 22, the copper wires 50 achieve a preliminary solidification state.

[0068] S5. Start the second motor 243 to drive the two second connecting shafts 24 on the same side to rotate. The rotation of the two second connecting shafts 24 drives the second gear 242 to roll back and forth on the rack 21 on each side. The second connecting shafts 24 drive the ultrasonic roller 23 and its internal vibrator 230 to rotate simultaneously. The vibrator 230 rotates to generate high-frequency vibration, and transmits the high-frequency vibration to the outer wall of the ultrasonic roller 23. Finally, the ultrasonic roller 23 is used to roll the initially solidified copper wire 50.

[0069] S6. While the ultrasonic roller 23 is working, the inert gas in the inert gas tank 3 is used to protect the rolling area of ​​the copper wire 50. The inert gas is sprayed into the rolling groove 121 through the air pipe 31 to prevent the copper base from oxidizing.

[0070] In the above process, the graphene aqueous solution in the graphene immersion tank 6 is composed of the following components by weight: 35 parts flake graphite, 3 parts sodium nitrate, 20 parts concentrated sulfuric acid, 2 parts potassium permanganate, 6 parts hydrogen peroxide, and 15 parts deionized water. The use of graphene can protect the copper wire from deep penetrating oxidation, greatly reducing the oxidation rate of copper. The copper wire 50 is initially compressed by the pressure roller 22, with the compression force generally between 5-20 kgf. After the pressure roller 22 is used for consolidation, the copper wires are initially bonded together. Then, the ultrasonic roller 23 is used for roll pressing and consolidation. During the ultrasonic roller 23 process, an inert gas is introduced into the rolling area for protection to prevent oxidation of the copper matrix. Finally, through this composite consolidation method, a high-performance copper-based composite material with high conductivity is quickly obtained.
