Description

Technical Field

[0001] The present invention belongs to the technical field of copper-clad aluminum wires, and in particular relates to copper-clad aluminum wire covering welding equipment and a welding method. Background Art

[0002] Copper-clad aluminum wire (CCA) is a wire with an aluminum core and a copper coating. It can be used as a conductor for coaxial cables and other electrical equipment. Aluminum wire has a low specific gravity, but its welding properties are poor. Therefore, a copper coating is applied to the aluminum wire to take advantage of aluminum's low specific gravity while also improving welding properties. For CCA welding, copper strips are typically used around the aluminum core, with the copper strips wrapped around the outer surface and welded together with welding equipment.

[0003] The copper-clad aluminum wire sheathing welding equipment in the prior art is difficult to sheath the aluminum wire core placed in the middle with the copper strip during use. The copper strip is bent and the aluminum wire core is inserted. During the actual welding process, the sheathing effect of the copper strip on the aluminum wire core is average, which makes the final welding sheathing stability poor. In addition, when the copper strip is pre-treated by bending and sheathing in advance, it is difficult to control the bending curvature. There are errors in the later insertion process with the aluminum wire core, making it difficult to achieve stable and effective sheathing processing. The actual sheathing accuracy is poor, which further reduces the quality of subsequent sheathing welding. In addition, the sheathing welding efficiency of the copper-clad aluminum wire of the target length is low, and the use effect is not good. Summary of the Invention

The bottom frame is fixedly connected to the bottom of the assembly frame and is located on the outside of the bottom plate.

The No. 2 gear is meshed and connected with the No. 1 gear.

[0012] A welding method for a copper-clad aluminum wire cladding welding device comprises the following steps:

[0013] Step 1: Insert the copper strip and aluminum wire core along the assembly frame and guide sleeve respectively, keeping the aluminum wire core above the copper strip. Start the motor in the No. 1 propulsion mechanism, so that the No. 1 damping plate of the No. 1 propulsion mechanism rotates and pushes the copper strip forward. At the same time, as the No. 1 propulsion mechanism drives the No. 2 damping plate of the No. 2 propulsion mechanism to rotate, the aluminum wire core is pushed forward at the same time.

[0014] Step 2: As the copper belt and the aluminum wire core move forward at the same time, the bottom surface of the copper belt contacts and rubs against the polishing plate in the polishing mechanism below it, gradually completing the sliding polishing of the bottom surface of the copper belt. When it is necessary to enhance the polishing effect, the adjustment mechanism is rotated so that the adjustment rod in the adjustment mechanism rotates upward and pushes the polishing mechanism upward to complete the enhanced friction polishing.

[0015] The third step: as the copper strip and the aluminum wire core move forward synchronously, the air pump is started, so that the air pump passes the gas into the middle tube through the No. 1 tube, the solenoid valve and the No. 2 tube, and passes the gas into the side frames on both sides. As the gas pressure in the side frames increases and pushes the internal movable plate to tilt upward, as the No. 1 spring is stretched, the movable plate drives the push plate tilted below the copper strip to move upward, and at the same time, the top of the push plate tilts and rises from left to right, so that the advancing copper strip is quickly folded under the upward movement of the push plate below, and then the two sides of the copper strip are folded upward and wrapped around the top of the aluminum wire core. At the same time, the welding part at the top is started, and the welding is completed at the junction of the copper strip and the aluminum wire core wrapped below. After the push plates on both sides move into place, the solenoid valve is started, so that the solenoid valve closes the No. 2 tube and opens the air guide tube, so that the continuously introduced gas is introduced into the air guide tube and blown out along the curved tubes on both sides. After the welding is completed, both sides of the copper clad aluminum wire are blown by the air and quickly cooled.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention utilizes the No. 1 propulsion mechanism and the No. 2 propulsion mechanism to rotate from the bottom and the top respectively, and pushes the copper strip from the bottom and the aluminum wire core from the top respectively, so that the aluminum wire core is located on the copper strip and moves synchronously, and cooperates with the push plate at the oblique bottom to squeeze and push during the movement. As the air pump introduces power gas into the side frame, the push plate is pushed at the oblique top. In conjunction with the position arrangement and top shape of the push plate, the copper strip is forced to fold upward from the bottom of both sides during the pushing process, and the covering of the top aluminum wire core is completed. The actual automatic covering effect is good, and the covering process is continuous and stable. In conjunction with the welding part on the top, stable and effective welding is completed from the top covering junction while completing the folding covering. The covering size is accurate and reasonable, the actual covering welding efficiency is high, the effect is good, and it is easy to use.

[0018] 2. The present invention utilizes the ventilation effect of the air pump and cooperates with the valve core action of the electromagnetic valve to achieve the change of ventilation direction. When the copper strip is coated, the incoming gas is introduced into the side frame and the push plate is pushed to move up and tilted to complete the coating and folding of the copper strip. After being pushed to the positioning position, the ventilation direction is switched through the electromagnetic valve to achieve the internal sealing of the side frame to maintain the stability of the folding. At the same time, the gas blown by the air pump is introduced into the air guide pipe, and in conjunction with the curved pipes connected on both sides of the air guide pipe, after the copper-clad aluminum wire is welded, it gradually receives the cooling air blown out from both sides after moving forward, which greatly improves the cooling speed after actual welding, improves the subsequent transfer efficiency, and has a good use effect.

[0019] 3. The present invention adds a polishing mechanism inside the assembly frame and utilizes the polishing plate on the top surface of the polishing mechanism. In the process of pushing by the No. 1 pushing mechanism and the No. 2 pushing mechanism, the copper strip is gradually moved laterally, and friction polishing is performed along the polishing plate in contact with the bottom during the lateral movement process, so that the surface of the copper-clad aluminum wire that has completed the coating welding has good smoothness. The surface polishing process is completed during the coating welding process, which reduces the workload of subsequent surface treatment, further improves efficiency, and has a good use effect.

The motor 282 in the No. 1 propulsion mechanism 28 is started, so that the No. 1 damping plate 284 of the No. 1 propulsion mechanism 28 rotates and pushes the copper strip 8 forward. At the same time, as the No. 1 propulsion mechanism 28 drives the No. 2 damping plate 293 in the No. 2 propulsion mechanism 29 to rotate, the aluminum wire core 9 is pushed forward at the same time. As the copper strip 8 and the aluminum wire core 9 move forward synchronously, the air pump 18 is started, so that the air pump 18 passes the gas through the No. 1 pipe 19, the solenoid valve 20 and the No. 2 pipe 21 into the middle pipe 17, and passes the gas into the side frames 12 on both sides.

After the welding is completed, the two sides of the copper clad aluminum wire are subjected to the air blowing and are quickly cooled down.

[0033] First, by utilizing the No. 1 propulsion mechanism 28 and the No. 2 propulsion mechanism 29 to rotate from the bottom and the top respectively, and push the copper strip 8 from the bottom and the aluminum wire core 9 from the top respectively, the aluminum wire core 9 is positioned on the copper strip 8 for synchronous movement, and cooperates with the push plate 14 at the lower side to squeeze and push during the forward movement. As the air pump 18 introduces the power gas into the side frame 12, the push plate 14 is pushed at the upper side.

[0036] Among them, the polishing mechanism 26 includes a mounting plate 261, a polishing plate 262, a sleeve rod 263, a bottom plate 264, a second spring 265 and an adapter 266. The polishing plate 262 and the sleeve rod 263 are fixedly connected to the upper and lower surfaces of the mounting plate 261 respectively.

[0041] Second embodiment: As the copper belt 8 and the aluminum wire core 9 advance simultaneously, the bottom surface of the copper belt 8 contacts and rubs against the polishing plate 262 in the polishing mechanism 26 below it, gradually completing the sliding polishing of the bottom surface of the copper belt 8. When it is necessary to enhance the polishing effect, the adjusting mechanism 27 is rotated so that the adjusting rod 272 in the adjusting mechanism 27 rotates upward and pushes the polishing mechanism 26 upward to complete the enhanced friction polishing.

[0042] First, by adding a polishing mechanism 26 inside the assembly frame 1, using the polishing plate 262 on the top surface of the polishing mechanism 26, in the process of cooperating with the pushing mechanism No. 1 28 and the pushing mechanism No. 2 29, the copper strip 8 is gradually moved laterally, and friction polishing is performed along the polishing plate 262 in contact with the bottom during the transverse movement process, so that the surface of the copper-clad aluminum wire that has completed the coating welding has good smoothness, and the surface polishing treatment is completed during the coating welding process, which reduces the workload of subsequent surface treatment, further improves efficiency, and has a good use effect.

[0043] A welding method for a copper-clad aluminum wire cladding welding device comprises the following steps:

[0044] Step 1: Insert the copper strip 8 and the aluminum wire core 9 along the assembly frame 1 and the guide sleeve 7 respectively, keeping the aluminum wire core 9 above the copper strip 8, and start the motor 282 in the No. 1 propulsion mechanism 28, so that the No. 1 damping plate 284 of the No. 1 propulsion mechanism 28 rotates and pushes the copper strip 8 forward. At the same time, as the No. 1 propulsion mechanism 28 drives the No. 2 damping plate 293 in the No. 2 propulsion mechanism 29 to rotate, the aluminum wire core 9 is also pushed forward.

[0045] Step 2: As the copper strip 8 and the aluminum wire core 9 advance simultaneously, the bottom surface of the copper strip 8 contacts and rubs against the polishing plate 262 in the polishing mechanism 26 below it, gradually completing the sliding polishing of the bottom surface of the copper strip 8. When it is necessary to enhance the polishing effect, the adjusting mechanism 27 is rotated so that the adjusting rod 272 in the adjusting mechanism 27 rotates upward and pushes the polishing mechanism 26 upward, completing the enhanced friction polishing.

[0046] Step 3: As the copper strip 8 and the aluminum wire core 9 advance synchronously, the air pump 18 is started, so that the air pump 18 passes the gas into the middle tube 17 through the No. 1 pipe 19, the solenoid valve 20 and the No. 2 pipe 21, and passes the gas into the side frames 12 on both sides. As the gas pressure in the side frames 12 increases and pushes the internal movable plate 13 to move up, as the No. 1 spring 15 stretches, the movable plate 13 drives the push plate 14 tilted below the copper strip 8 to move up, and at the same time cooperates with the top of the push plate 14 to tilt and rise from left to right, so that the copper strip 8 in progress moves downward at an angle. The square push plate 14 moves upward and squeezes the copper strip 8 to fold over quickly, so that both sides of the copper strip 8 are folded upward and covered on the top of the aluminum wire core 9. At the same time, the welding part 4 located above is started to complete the welding at the intersection of the copper strip 8 and the aluminum wire core 9 covered below. As the push plates 14 on both sides move into place, the solenoid valve 20 is started, so that the solenoid valve 20 closes the No. 2 pipe 21 and opens the air guide pipe 22 at the same time, so that the continuously introduced gas is introduced into the air guide pipe 22 and blown out along the curved pipes 30 on both sides. After the welding is completed, both sides of the copper clad aluminum wire are blown by the air and quickly cooled down.
