Description

Technical Field

[0001] The invention relates to the technical field of transformer production and processing, and in particular to an automatic wire splitting machine for transformer production and processing. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. In the production device or equipment used to produce small transformers, a wire splitter is required, and the cables need to be stripped.

[0003] For example, a patent entitled: An automatic wire splitting machine for transformer production and processing (patent application number: CN202122318921.0) discloses an automatic wire splitting machine for transformer production and processing, which is provided with a wire-receiving and wiring structure, so that the stripped cables can be evenly collected on the winding roller, making the wire reeling more uniform and increasing the aesthetics of the cables after collection. In addition, an automatic stripping structure is provided, which can squeeze and separate the cable sheath from the wire core after cutting, so that the wire core can be directly collected on the winding roller, and the cable sheath is stripped and collected separately, thereby simplifying the sheath stripping operation and increasing work efficiency. However, some types of cables are relatively hard, and direct cutting will increase the wear of the cutting structure, especially in low temperatures.

[0004] Therefore, in the prior art, an automatic wire splitting machine for transformer production and processing is also used in conjunction with a heating and softening device to strip cables that are hard or hardened. However, during the softening process, the entire cable is softened, and it is inconvenient to feed the entire softened cable. Moreover, the softening time of the cable is relatively long, and it takes a long time to complete the softening of the cable. In addition, since the material of the cable is plastic, its internal structure changes after being heated and softened, and it has a certain viscosity, so that when the cutting knife is stripping the wire, the cutting knife will exert a certain thrust on the cable that is in contact with it. This will cause the softened parts of the subsequent cables to be squeezed together due to the presence of the thrust, and the squeezed cables may block the entrance of the cutting unit. In order to solve the above problems, an automatic wire splitting machine for transformer production and processing is proposed. Summary of the invention

The multiple upper round boxes 2 and the multiple lower round boxes 3 are provided to ensure a heating path of sufficient length and improve the heating effect.

[0047] An upper circular hole 28 is provided on the slide box 23, and an upper cylinder 26 is rotatably connected inside the upper circular hole 28.

[0049] By providing structures such as the through hole 5 and the stopper 35 , a high-temperature airflow is formed only at the cable, thereby improving the utilization efficiency of the high-temperature gas, ensuring the heating effect, and reducing energy consumption.

[0051] When the cable moves, the elastic ring piece 6 adheres to the cable sheath, dividing the cable sheath into a heating area (the upper and lower ends of the cable) and a non-heating area (the left and right ends of the cable). The heating area softens, while the non-heating area is less affected by the high-temperature gas and still maintains its original hardness. The cable sheath is cut in the heating area using a wire stripping cutter 8, and the non-heating area is used to ensure the hardness of the cable sheath.

[0052] By providing the elastic ring piece 6, the cable sheath is divided into a heating area and a non-heating area, so as to prevent the cable sheath from sliding as a whole or wrinkling due to the force of the wire stripping cutter 8 during the slitting process, thereby facilitating slitting.

[0053] Reference Figure 5 , Figure 6 , Figure 7 As shown in , a wire splitting drum 7 is fixedly connected to one end of the support frame 39 close to the winding roller 14, and two wire stripping cutters 8 are provided. The cable passes through the inside of the wire splitting drum 7, and the two wire stripping cutters 8 are respectively fixedly connected to the upper and lower ends of the inside of the wire splitting drum 7, and the upper and lower ends of the cable outer skin are cut at the same time, so that the cable outer skin is cut into two parts.

[0054] Reference Figure 7As shown in the figure, after slitting, the wire core passes through the wire core perforation 11, wherein half of the cable sheath passes through the first sheath perforation 9 and the second sheath perforation 12 located at the upper end of the figure in sequence, and the other half of the cable sheath passes through the first sheath perforation 9 and the second sheath perforation 12 located at the lower end of the figure in sequence, and when the cable moves, the effect of automatic peeling of the cable sheath can be achieved.

[0055] Moreover, cutting after heating can reduce the wear of the wire stripping cutter 8 and improve the use efficiency of the automatic wire splitting machine used in transformer production and processing.

[0056] Reference Figure 2 , Figure 3 As shown in , in order to realize the winding of the wire core, a bracket 13 is fixedly connected to the base 1, and a winding roller 14 for winding the wire core is arranged above the base 1. The winding roller 14 is rotatably connected to the bracket 13, and a first motor 15 is fixedly connected to the bracket 13. The winding roller 14 is fixedly connected to the driving shaft of the first motor 15. The first motor 15 drives the winding roller 14 to rotate, and the winding roller 14 winds the wire core.

[0057] A lead screw 16 is rotatably connected to the bracket 13. The lead screw 16 is located on the side of the winding roller 14 close to the upper round box 2. A slide 18 is matched with the lead screw 16. A threading ring 19 is rotatably provided on the top of the slide 18. A guide rod 17 is fixedly connected to the bracket 13. A circular groove matching the guide rod 17 is provided on the slide 18. A second motor 20 is fixedly connected to the bracket 13. The lead screw 16 is fixedly connected to the driving shaft of the second motor 20. The wire core passes through the threading ring 19 and is then wound on the winding roller 14. When the winding roller 14 winds up the wire core, the second motor 20 drives the lead screw 16 to rotate, and with the cooperation of the guide rod 17, the slide 18 drives the threading ring 19 to move back and forth, so that the wire core is evenly wound on the winding roller 14.

[0058] Working principle: The cable passes through the upper round box 2 and the lower round box 3. When high-temperature gas is transported to the upper round box 2 and the lower round box 3, the high-temperature gas will be sprayed toward the cable through the corresponding through hole 5. The high-temperature airflow acts on the outer skin of the cable to heat the outer skin of the cable, so that the outer skin of the cable is softened and easy to cut.

[0059] When the cable passes through and moves between the upper round box 2 and the lower round box 3, the friction force will drive the upper round box 2 and the lower round box 3 to rotate, and the rotation of the upper round box 2 and the lower round box 3 can reduce the wear of the cable; in addition, when one of the arc blocks 37 contacts the cable, the arc block 37 drives the corresponding square rod 34 and the stopper 35 to move away from the cable due to the squeezing effect of the cable, so that the corresponding through hole 5 is opened. At the same time, with the movement of the stopper 35, the piston rod 46 moves toward the cylinder body 41 in the stroke sleeve 1 42, squeezing the hot air inside the cylinder body 41, so that the hot air inside the cylinder body 41 flows rapidly toward the stroke sleeve 2 43, thereby pushing the connecting piece 44 to move away from the cylinder body 41, so that the punching nail 45 can pierce the cable sheath, and multiple sets of punching nails 45 need to be used in coordination, which can gradually Cylindrical holes are nailed on the outer skin of the cable, and hot air sprayed toward the cable enters the holes, so that the hot air can contact the outer skin of the cable more completely, accelerating the softening of the outer skin of the cable. Moreover, this will make the contact between the wire stripping cutter 8 and the cable intermittent, so that the cable will not be deformed during the feeding process due to the relative thrust applied to it by the wire stripping cutter 8 (which may cause the cable to deform), preventing the softened cable outer skin from crowding each other after deformation and blocking the wire inlet of the wire distribution barrel 7. After the arc block 37 is separated from the cable, as the spring 36 is reset, the stopper 35 is reset, so that the punching nail 45 is reset, and the arc block 37 at other positions does not contact the cable, and the corresponding stopper 35 closes the through hole 5, so that only high-temperature airflow is formed at the cable, thereby improving the utilization efficiency of the high-temperature gas and ensuring the heating effect.

[0060] When the cable moves, the elastic ring piece 6 adheres to the cable sheath, dividing the cable sheath into a heating area (the upper and lower ends of the cable) and a non-heating area (the left and right ends of the cable). The heating area softens, while the non-heating area is less affected by the high-temperature gas and still maintains its original hardness. The cable sheath is cut in the heating area using a wire stripping cutter 8, and the non-heating area is used to ensure the hardness of the cable sheath.

[0061] The first outer skin perforation 9, the second outer skin perforation 12 and other structures are provided, so that the outer skin of the cable can be automatically peeled off when the cable moves.

[0062] The wire core is passed through the threading ring 19 and then wound on the winding roller 14. When the winding roller 14 winds up the wire core, the second motor 20 drives the lead screw 16 to rotate, and with the cooperation of the guide rod 17, the slide 18 drives the threading ring 19 to move back and forth, so that the wire core is evenly wound on the winding roller 14.

[0063] The above description is only a preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacement or changes to an automatic wire splitting machine for transformer production and processing and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
