Description

Technical Field

[0002] Building copper wire is widely used in the construction field. Its excellent conductivity, corrosion resistance and mechanical strength make it an important material for building electrical systems. In construction, copper wire needs to be wired according to different structures and design requirements. Bending can make copper wire better adapt to structures such as walls and ceilings, ensuring the reasonable layout of electrical lines. Bending copper wire can help realize the connection and distribution of power supply, especially where corners or changes in line direction are required. Bending can effectively guide the flow of current.

[0003] When bending architectural copper wires, a certain amount of dirt will adhere to the surface of the architectural copper wires, and the dirt will form stress concentration points during the bending process. These dirt will interfere with the uniform deformation of the copper wires, resulting in excessive local stress, thereby producing wrinkles and cracks. At the same time, the surface of the architectural copper wires will form an oxide layer due to oxidation, which will reduce the ductility and plasticity of the copper wires. During the bending process, the inner side of the copper wires is subjected to greater tensile stress, and the outer side is subjected to greater compressive stress. The presence of the oxide layer will cause the copper wires to wrinkle and crack under the action of these stresses. Simple wiping cannot remove the dirt and oxide layer on the surface, thereby reducing the bending effect of the copper wires. Summary of the invention

[0029] Reference Figure 2-3 The cutting mechanism 15 includes a fixed frame 151, which is fixedly connected to the vertical frame 1. A second electric telescopic rod 152 is fixedly connected to one side of the fixed frame 151, and a cutter 153 is fixedly connected to the telescopic end of the second electric telescopic rod 152. A knife holder 154 is fixedly connected to the other side of the vertical frame 1, and the cutter 153 cooperates with the knife holder 154.

[0030] Working principle:

[0031] One end of the building copper wire moves downward, and after moving downward for a distance, it passes through the cleaning pad 8. After the reduction motor 5 is powered on and started, it drives the connecting shaft 6 to rotate, and the connecting shaft 6 drives the first gear 7 to rotate, the first gear 7 drives the second gear ring 4 to rotate, the second gear ring 4 drives the rotating tube 3 to rotate, and the rotating tube 3 drives the cleaning pad 8 to rotate. The rotation speed of the rotating tube 3 is controlled by the coordination of the number of teeth between the first gear 7 and the second gear ring 4;

[0032] When the building copper wire moves downward, it contacts with the rotating cleaning pad 8, and the inner wall of the cleaning pad 8 is in close contact with the building copper wire. The cleaning pad 8 cleans the surface dirt of the building copper wire during the rotation process. The surface dirt of the building copper wire is subjected to the rotating friction force, and the building copper wire itself moves downward. The dirt on the surface of the building copper wire is subjected to a larger wiping force, so that the dirt is better separated from the surface of the building copper wire, thereby improving the treatment effect of the dirt on the surface of the building copper wire and effectively removing the dirt on the surface of the building copper wire;

[0033] The treated building copper wire passes through the liquid conducting pad 12, the conduit 13 is opened, the chemical polishing liquid in the liquid storage bottle 14 passes through the conduit 13 and enters the chamber 10, the chemical polishing liquid in the chamber 10 passes through the through hole 11 and contacts the liquid conducting pad 12, the chemical polishing liquid soaks the liquid conducting pad 12, the soaked liquid conducting pad 12 contacts the building copper wire, the chemical polishing liquid is applied to the building copper wire, the chemical polishing liquid contacts the oxide layer on the surface of the copper wire and reacts, thereby removing the oxide layer on the surface of the building copper wire;

[0034] The treated building copper wire passes through the dehumidification pad 9, and the dehumidification pad 9 cleans the residual liquid on the surface of the building copper wire. The cleaned building copper wire passes through the first gap, and the building copper wire contacts the fixed shaft 24 and the steel wheel 27. When the bending position of the building copper wire is located between the fixed shaft 24 and the steel wheel 27, the pushing of the building copper wire is stopped;

[0035] After the first electric telescopic rod 23 is powered on and started, it pushes the tooth plate 22 to move a set distance, and the tooth plate 22 drives the first tooth ring 26 to rotate, and the first tooth ring 26 drives the fixed disk 25 to rotate a set angle, and the fixed disk 25 rotates around the fixed shaft 24. After the fixed disk 25 rotates, it drives the steel wheel 27 to rotate. After the steel wheel 27 rotates, it is bent with the cooperation of the fixed shaft 24, and the surface dirt of the building copper wire is cleaned by the cleaning pad 8 during the rotation process. The surface dirt of the building copper wire is subjected to the rotating friction force, so that the dirt is better separated from the surface of the building copper wire, and the treatment effect of the dirt on the surface of the building copper wire is improved. The chemical polishing liquid reacts with the oxide layer on the surface of the copper wire after contacting, and removes the oxide layer on the surface of the building copper wire, removes the dirt and oxide on the surface of the building copper wire, and reduces the influence of the dirt and oxide on the bending, so that the building copper wire will not have wrinkles and cracks after bending, thereby improving the copper wire bending effect;

[0036] After the bending of the building copper wire is completed, the second electric telescopic rod 152 is started and drives the cutter 153 to move a set distance toward the knife seat 154. The cutter 153 contacts the building copper wire after moving a certain distance. After the cutter 153 continues to move, it cuts the building copper wire with the cooperation of the knife seat 154.

[0037] Embodiment 2: During the downward movement of the building copper wire, it contacts the cleaning pad 8, the liquid conducting pad 12, and the dehumidification pad 9. There is friction between the building copper wire and the cleaning pad 8, the liquid conducting pad 12, and the dehumidification pad 9, thereby affecting the downward movement of the building copper wire. If the building copper wire moves downward too fast, the surface treatment effect of the cleaning pad 8 and the liquid conducting pad 12 on the building copper wire will be reduced. If the building copper wire moves downward too slowly, the bending speed of the building copper wire will be reduced, thereby reducing the treatment effect of the building copper wire. Figure 5-8 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that a speed control mechanism 16 for pushing the copper wire to move on the rotating tube 3 is connected to the vertical frame 1, and the speed control mechanism 16 includes two parallel rotating rollers 161, the two parallel rotating rollers 161 are rotatably connected to the vertical frame 1, the two parallel rotating rollers 161 are located above the rotating tube 3, and a second gap is provided between the two parallel rotating rollers 161, each rotating roller 161 is sleeved with an anti-slip sleeve 163, the anti-slip sleeve 163 is a rubber sleeve, each rotating roller 161 is fixedly connected with a second gear 162, the two second gears 162 are meshed with each other, one of the rotating rollers 161 is fixedly connected with a large gear 165, one end of the connecting shaft 6 is fixedly connected with a small gear 164, and the small gear 164 is meshed with the large gear 165.

[0038] Working principle:

[0039] During the process of the connecting shaft 6 driving the first gear 7 to rotate, the small gear 164 is also driven to rotate, the small gear 164 drives the large gear 165 to rotate, the large gear 165 drives the rotating roller 161 to rotate, the rotating roller 161 drives the second gear 162 to rotate, the two second gears 162 mesh and rotate, so that the two rotating rollers 161 rotate synchronously, each rotating roller 161 drives the anti-skid sleeve 163 to rotate, the building copper wire passes through the second gap, the building copper wire contacts the anti-skid sleeve 163, and after the two rotating rollers 161 rotate, the building copper wire is pushed downward by the anti-skid sleeve 163, so that the building copper wire moves on the rotating tube 3, and the rotation speed of the rotating roller 161 is regulated by the coordination of the number of teeth between the small gear 164 and the large gear 165. While pushing the building copper wire downward, the moving speed of the building copper wire is controlled to avoid the building copper wire moving too fast or too slow, thereby ensuring the treatment effect of the cleaning pad 8 on the building copper wire.

[0040] Embodiment 3: During the process of the rotating roller 161 rotating and pushing the building copper wire downward, since there is a certain distance between the rotating roller 161 and the cleaning pad 8, after the building copper wire is pushed downward by the two rotating rollers 161, the copper wire between the rotating roller 161 and the cleaning pad 8 is easily bent under the push of the two rotating rollers 161, and a gap is generated between the concave surface of the bending part of the building copper wire and the cleaning pad 8, thereby reducing the treatment effect of the cleaning pad 8 on the building copper wire. Figure 8-9As another preferred embodiment of the present invention, the difference from Embodiment 1 is that a straightening mechanism 17 for preventing the copper wire from bending is connected to the vertical frame 1, and the straightening mechanism 17 includes a connecting plate 171, one end of the connecting plate 171 is fixedly connected to the vertical frame 1, and the other end of the connecting plate 171 is fixedly connected to an open frame 172, and the open frame 172 is located between the rotating roller 161 and the rotating tube 3. A plurality of extrusion wheels 173 are rotatably connected to the two sides of the open frame 172 at equal intervals along the length direction, and a third gap is provided between the extrusion wheels 173 on both sides, and the third gap is located directly below the second gap. A connecting rod 174 is fixedly connected to the upper end of the connecting plate 171, and one end of the connecting rod 174 is fixedly connected to a limiting tube 175, and the limiting tube 175 is located directly above the second gap. The bottom end of the limiting tube 175 is detachably connected to a scraper head 176.

[0041] Working principle:

[0042] The connecting plate 171 fixes the open frame 172, and the open frame 172 is located between the rotating roller 161 and the cleaning pad 8. The building copper wire passing through the second gap passes through the third gap again, and the building copper wire contacts the extrusion wheels 173 on both sides. During the process of the two rotating rollers 161 rotating and pushing the building copper wire to move downward, the extrusion wheels 173 on both sides roll the building copper wire on the third gap, straighten the bending part of the building copper wire, so that the building copper wire between the rotating roller 161 and the cleaning pad 8 is in a straight state, thereby ensuring that the inner wall of the cleaning pad 8 contacts the surface of the building copper wire, ensuring the cleaning effect of the cleaning pad 8 on the building copper wire, and at the same time, the connecting rod 174 fixes the limiting tube 175, and the limiting tube 175 limits the building copper wire so that the building copper wire is accurately inserted into the second gap, and the scraper head 176 is fixed at the bottom end of the limiting tube 175, and the inner wall of the bottom end of the scraper head 176 contacts the building copper wire, and the surface of the building copper wire is pre-cleaned, thereby improving the dirt treatment effect on the surface of the building copper wire.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
