[0002] Patent CN118888222B discloses a production device for corrosion-resistant steel-core aluminum stranded wire. It vertically stacks a frame stranding machine and two electrolyte cells. Although this allows the ceramic film layer on the surface of the steel core and aluminum conductor to grow more evenly, the entire set of equipment is difficult to install. The vertical setting of the frame stranding machine makes loading inconvenient, and the large height difference between the two electrolyte cells results in high energy consumption of the circulating water pump. Summary of the Invention

[0003] The purpose of the present invention is to provide a horizontal corrosion-resistant steel core aluminum stranded wire production equipment, which improves the problems of difficult installation, inconvenient loading and high energy consumption of circulating water pumps in existing production equipment without affecting the uniformity of ceramic film growth.

The stranding drum has a center hole, and several wire holes are located around the center hole. The center hole, wire holes, and wiring holes are all plugged. The steel core passes through the electrolyte tank through the center hole. The aluminum conductor is drawn from the stranding machine, passed through a cable hole, and then entered the electrolyte tank. The stranding machine rotates around the steel core, and the stranding drum rotates synchronously with the stranding machine, twisting the aluminum conductor passed through the stranding drum onto the steel core. The aluminum conductor and the steel core are twisted together in the cylindrical electrode, and the stranded aluminum-steel core wire is then passed through the cable hole. An oxidation power source is also included, and the cylindrical electrode and the aluminum-steel core wire are connected to the oxidation power source separately.

[0019] The following describes the technical solution of the present invention in a clear and complete manner, with reference to specific embodiments. The pre-coated insulating film, the simultaneous plating of the steel core and aluminum conductor in the same bath, the electrolyte and its circulation system, the oxidizing power source, the plating bath system, and the silicone plugs involved are all prior art.

[0020] Example 1

[0021] like Figure 1-3 As shown, a horizontal, corrosion-resistant steel-core aluminum stranded wire production apparatus includes a stranding machine (not shown), an electrolyte tank 1, and a cylindrical electrode 2. The stranding machine is located on one side of the electrolyte tank 1. The cylindrical electrode 2 is placed horizontally in the electrolyte tank 1. The electrolyte tank 1 contains electrolyte and is also connected to an electrolyte circulation system. The cylindrical electrode 2 is immersed in the electrolyte. The steel core 3 passes through the stranding machine and the electrolyte tank 1 from left to right. The surface of the steel core 3 has a pre-coated insulating film layer.

[0022] A stranding drum 5 is located on one side of the electrolyte cell 1, and a wiring hole 101 is located on the other side. The stranding drum 5 has a central hole 501, surrounded by ten wire holes 502, distributed axially symmetrically around the central hole 501. Alternatively, when producing multi-layer steel-core aluminum stranded wire, the wire holes 502 can be arranged in multiple concentric circles around the central hole 501. The steel core 3 passes through the electrolyte cell 1 through the central hole 501 and is positioned on the axis of the cylindrical electrode 2. Aluminum conductor 6 is drawn from a stranding machine and passed through the wire holes 502 into the electrolyte cell 1. The stranding machine rotates around the steel core 3, and the stranding drum 5 rotates synchronously with the stranding machine, stranding the aluminum conductor 6 that has passed through the stranding drum 5 onto the steel core 3. The junction between the aluminum conductor 6 and the steel core 3 is located within the cylindrical electrode 2. The stranded steel-core aluminum stranded wire 7 then exits through the wiring hole 101. There are silicone plugs on the center hole 501, the wire hole 502 and the wiring hole 101. The cylindrical electrode 2 and the steel core aluminum stranded wire 7 are connected to the oxidation power supply respectively.

[0023] The electrolyte cell 1 has a bearing seat on its sidewall. The winding drum 5 has an annular flange 503, which has an annular bearing mounted on the annular flange 503. The annular bearing is assembled within the bearing seat. The winding drum 5 can be secured to the turntable of the frame stranding machine via a coupling so that the winding drum 5 rotates synchronously with the frame stranding machine. As another preferred embodiment, the electrolyte cell 1 has an interlayer 102 on its sidewall. The interlayer 102 contains a motor 8. The output shaft of the motor 8 has a gear. The outer edge of the winding drum 5 (the area with a smaller diameter than the annular flange) has a gear ring, which meshes with the gear ring. Driven by the motor 8, the winding drum 5 rotates synchronously with the frame stranding machine. The winding drum 5, which is located on the sidewall of the plating cell, strands the aluminum conductor 6 onto the steel core 3. The steel core 3 and the aluminum conductor 6 are twisted together within the cylindrical electrode 2 while undergoing oxidation coating. Each aluminum conductor 6 rotates around the axis of the cylindrical electrode 2 within the cylindrical electrode 2, undergoing the same thermoelectrochemical oxidation conditions to form a uniform ceramic film layer.
