Description

Technical Field

[0002] Paper-covered copper wire is a winding wire made from oxygen-free copper rod or electrical round aluminum rod extruded or drawn through a die of specified specifications, then wrapped with a specific insulating material. Composite conductors are made from several winding wires or copper and aluminum conductors arranged according to specified requirements and wrapped with a specific insulating material. They are primarily used for windings in oil-immersed transformers, reactors, and other electrical devices.

New insulation needs to be replaced for processing.

[0017] Technical effects and advantages of the present invention:

[0018] In order to solve the problem that the ends of the copper wires are relatively sharp and easily puncture the insulation, the present invention improves the cutting mechanism. The copper wire is cut into two sections with spherical ends by using an arc-shaped protrusion. The spherical ends have a hemispherical structure. The spherical ends keep the ends of the copper wire in a hemispherical and rounded state after being cut, thereby protecting the wrapped cable paper insulation layer, making it difficult to puncture the wrapped cable paper insulation layer, and reducing the damage rate of the wrapped cable paper insulation layer.

[0019] In order to solve the problem that the copper wire is easily retracted into the wrapped cable paper insulation layer, the present invention provides grooves on the surface of the cutting plate. The grooves are located on both sides of the arc-shaped protrusion and have a hemispherical groove structure. When the two cutting plates move toward each other to cut the copper wire into two sections, a point protrusion is formed on the outer ring surface of the copper wire that is squeezed into the groove, and the wrapped cable paper insulation layer is tightly wrapped around the outside of the point protrusion, so that the wrapped cable paper insulation layer is tightened from the inner ring, thereby increasing friction resistance and preventing the copper wire from retracting into the wrapped cable paper insulation layer.

[0020] The present invention is designed according to actual needs. Since the arc-shaped protrusion cuts the end of the copper wire into a spherical end, the end of the copper wire will inevitably be squeezed. The design of the groove on the cutting plate just makes up for the defect that the copper wire end cannot release stress when it is squeezed. When the copper wire end is squeezed, the extrusion force can squeeze the excess molecular structure on the copper wire into the groove to form a point protrusion, thereby avoiding the phenomenon of cracking, breaking, etc. caused by excessive extrusion pressure on the copper wire end.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The present invention provides Figures 1-11 The paper-wrapped copper wire cutting device shown includes a cutting machine 1 for cutting a copper wire 4. A protective mechanism 3, a transmission mechanism 2, and a cutting mechanism 5 are sequentially mounted above the cutting machine 1. The copper wire 4 passes through the protective mechanism 3, the transmission mechanism 2, and the cutting mechanism 5. The protective mechanism 3 coats the surface of the copper wire 4 with oil. The transmission mechanism 2 is used to provide power for the copper wire 4. The cutting mechanism 5 is used to cut the copper wire 4. The outer ring of the copper wire 4 is coated with a wrapped cable paper insulation layer 35.

[0035] In order to solve the problem that the end of the copper wire 4 is relatively sharp and easily punctures the insulation skin, the cutting mechanism 5 is improved. Specifically, the cutting mechanism 5 includes an upper cutting die 12 and a lower cutting die 13 arranged above and below. The upper cutting die 12 and the lower cutting die 13 are fixed by fixing screws 11. The upper and lower cutting dies 12 and 13 are each provided with a through groove 17 for the copper wire 4 to pass through on the side close to each other. Cutting chambers 27 are provided at the upper and lower positions of the middle of the through groove 17. The two cutting chambers 27 are respectively arranged inside the upper cutting die 12 and the lower cutting die 13. The ends of the two cutting chambers 27 away from each other are both provided with openings. The opening of one cutting chamber 27 is located on the side of the upper cutting die 12 away from the lower cutting die 13, and the opening of the other cutting chamber 27 is located on the side of the lower cutting die 13 away from the upper cutting die 1 2, a cutting plate 25 is movably provided in the cutting chamber 27, and an arc-shaped protrusion 26 is integrally provided at the middle position of the side where the two cutting plates 25 are close to each other. A cylinder 28 is provided on the side where the two cutting plates 25 are away from each other. One end of the cylinder 28 away from the cutting plate 25 is fixedly connected to the sealing plate 29, and the sealing plate 29 is fixedly installed at the opening of the cutting chamber 27. When the two cylinders 28 push the two groups of cutting plates 25 toward each other, the arc-shaped protrusion 26 is used to cut the copper wire 4 into two sections with a spherical end 33 at the end. The spherical end 33 has a hemispherical structure. The spherical end 33 allows the copper wire 4 to maintain a hemispherical rounded state after being cut, thereby protecting the wrapped cable paper insulation layer 35, making it difficult to puncture the wrapped cable paper insulation layer 35, and reducing the damage rate of the wrapped cable paper insulation layer 35.

[0036] Furthermore, in order to solve the problem that the copper wire 4 is easily retracted into the wrapped cable paper insulation layer 35, a groove 24 is provided on the surface of the cutting plate 25. The groove 24 is located on both sides of the arc-shaped protrusion 26. The groove 24 has a hemispherical groove structure. When the two cutting plates 25 move toward each other to cut the copper wire 4 into two sections, the outer ring surface of the copper wire 4 forms a point protrusion 34 squeezed into the groove 24, and the wrapped cable paper insulation layer 35 is tightly wrapped around the outside of the point protrusion 34, so that the wrapped cable paper insulation layer 35 is tightened from the inner ring, thereby increasing the friction resistance and avoiding the phenomenon of the copper wire 4 retracting into the wrapped cable paper insulation layer 35.

[0037] In order to make it easier to cut the copper wire 4 when the upper and lower cutting plates 25 move toward each other, a heating chamber 18 is provided inside the lower cutting die 13. A heat supply pipe 14 connected to the heating chamber 18 is fixedly provided at the bottom of the lower cutting die 13. The heating chamber 18 surrounds the periphery of the cutting plate 25. The heat supply pipe 14 supplies hot air to the heating chamber 18, thereby transferring the heat in the hot air to the cutting plate 25 through the wall of the lower cutting die 13, thereby achieving the purpose of hot cutting the copper wire 4, making the copper wire 4 easier to cut. A control valve 16 is provided on the heat supply pipe 14 to facilitate the control of the heat. The control valve 16 uses a solenoid valve or a manual valve and is designed according to actual needs. Since the arc-shaped protrusion 26 cuts the end of the copper wire 4 into a spherical end 33, the end of the copper wire 4 will inevitably be squeezed. The design of the groove 24 on the cutting plate 25 just makes up for the defect that the end of the copper wire 4 cannot release stress when it is squeezed. When the end of the copper wire 4 is squeezed, the extrusion force can squeeze the excess molecular structure on the copper wire 4 into the groove 24 to form a point protrusion 34, thereby avoiding the cracking, breakage and the like caused by excessive extrusion pressure on the end of the copper wire 4.

[0038] In order to make full use of the waste heat in the heating chamber 18, a circulation pipe 19 is provided at the end of the bottom of the lower cutting mold 13 away from the heat supply pipe 14, the end of the circulation pipe 19 is connected to the heat supply pipe 14, and a heat exhaust pipe 22 is provided on the side of the end of the circulation pipe 19 connected to the heat supply pipe 14, a first solenoid valve 21 is provided in the heat exhaust pipe 22, and a second solenoid valve 23 is provided at the end of the circulation pipe 19 connected to the heat supply pipe 14, and a temperature sensor 20 for monitoring the temperature is provided in the circulation pipe 19. The gas transported to the heating chamber 18 by the heat supply pipe 14 is discharged from the circulation pipe 19 and the heat exhaust pipe 22. When the temperature sensor 20 detects that the temperature of the discharged gas is high, the first solenoid valve 21 can be closed and the second solenoid valve 23 can be opened, so that the gas circulates through the heat supply pipe 14 into the heating chamber 18 for utilization, thereby making full use of the waste heat.

[0039] Considering that the copper wire 4 is easily oxidized when heated when being cut, a protective mechanism 3 is provided on the cutting machine 1. The protective mechanism 3 includes a coating wheel assembly 7 and a first motor 8. The first motor 8 is fixedly mounted on the upper surface of the cutting machine 1.

The cotton absorption layer 50 and the cotton coating layer 47 are connected by a cotton strip 52. The oil stored in the wheel cavity 49 is absorbed and coated on the outer ring of the copper wire 4 through the cotton absorption layer 50, the cotton strip 52 and the cotton coating layer 47 in turn, thereby preventing the copper wire 4 from being oxidized during cutting, and playing a good protective role. An addition pipe 53 for adding oil to the wheel cavity 49 is provided on the side of the coating wheel 48, and a one-way valve is provided in the addition pipe 53 to supply oil into the wheel cavity 49 in one direction.

A guide ring 32 for the copper wire 4 to pass through is provided in the middle position of the side where the upper guide plate 30 and the lower guide plate 31 are close to each other. The guide 6 has a guiding function for the copper wire 4.

[0041] In order to allow the copper wire 4 to pass through the protection mechanism 3, the transmission mechanism 2 and the cutting mechanism 5 in sequence, the transmission mechanism 2 includes a conveyor belt 39, a guard plate 9 and a transmission wheel 37. A pair of conveyor belts 39 are provided, and four transmission wheels 37 are provided. A pair of conveyor belts 39 are squeezed on both sides of the copper wire 4.

The conveyor belt 39 transmission sleeve is arranged on the transmission wheels 37 at both ends thereof. The guard plate 9 is provided to protect the outside of the conveyor belt 39, and the guard plate 9 is fixedly installed on the upper surface of the cutting machine 1. The motor is not shown in the figure. When the motor drives the transmission wheel 37 to rotate, the transmission wheel 37 drives the conveyor belt 39 to transmit. When the conveyor belt 39 is transmitted, the copper wire 4 between the pair of conveyor belts 39 is squeezed to move.

[0042] Taking into account the processing of copper wires 4 of different diameters, the transmission mechanism 2 also includes an adjustment mechanism for adjusting the gap between a pair of conveyor belts 39, the adjustment mechanism includes an adjustment wheel 10, a pressure wheel 38, a positioning ring 54, an adjustment rod 56, a positioning slide 55 and a slider 57, the positioning slide 55 and the positioning ring 54 are fixedly mounted on the upper surface of the cutting machine 1, the positioning ring 54 is located in the middle of the positioning slide 55, the slider 57 is slidably connected to the upper surface of the positioning slide 55, and there are two sliders 57, each of which is fixed with two pressure wheels 38, two The pressure wheel 38 is arranged between the two corresponding transmission wheels 37, and the middle part of the adjusting rod 56 is rotatably connected to the positioning ring 54. The outer rings of both ends of the adjusting rod 56 are provided with positive threads and negative threads. Both ends of the adjusting rod 56 pass through the two sliders 57 at the same time. The adjusting rod 56 and the sliders 57 are connected by threaded cooperation. The adjusting wheel 10 is fixedly installed at one end of the adjusting rod 56. When the adjusting wheel 10 is held and the adjusting rod 56 is rotated, the two sliders 57 move toward or away from each other, so that the distance between a pair of conveyor belts 39 changes to adapt to copper wires 4 of different diameters.

[0043] In order to ensure that the connection structure between the copper wire 4 and the wrapped cable paper insulation layer 35 is further stable, a grinding mechanism 36 for grinding the copper wire 4 is provided at one end of the through groove 17 close to the transmission mechanism 2.

When the second motor 40 drives the driving shaft 42 to rotate, the driving gear 41 and the tooth blocks 43 are engaged, and the rotating ring 46 rotates. The rotating ring 46 uses the cotton layer 45 to evenly apply the oil on the outer ring of the copper wire 4, and the sand-surfaced grinding ring 44 grinds the outer ring of the copper wire 4 into a sand surface, thereby increasing the friction resistance between the outer ring of the copper wire 4 and the inner wall of the wrapped cable paper insulation layer 35, and further preventing the copper wire 4 from moving in the wrapped cable paper insulation layer 35.
