Description

Technical Field

[0001] This invention relates to the field of electromagnetic wire processing technology, and in particular to a multi-channel rapid cutting device for electromagnetic wire processing. Background Technology

[0002] Magnetizing wire mainly consists of a copper conductive core and an insulating varnish layer covering the outer surface of the copper wire, with the copper wire serving as the core carrier for current transmission. In the finished product processing of magnetizing wire, the copper wire needs to be cut to a fixed length according to the actual application specifications. However, because the copper wire is stored and transported in coiled form, it remains in a coiled state for extended periods, accumulating residual bending stress. After cutting, this stress release causes the cut wire to spring back and bend, failing to meet the straightness standards for subsequent assembly.

[0003] While existing heating straightening processes can release stress and straighten straight wires, during continuous production, the same wire simultaneously has a section that expands when heated and a section that contracts when cooled. The thermal expansion and contraction effect can cause axial movement at the wire end, resulting in a decrease in the dimensional accuracy of fixed-length cutting. At the same time, conventional single-station cooling structures require repeated heating and cooling, resulting in long cooling cycles and low production efficiency, making it difficult to adapt to continuous high-speed cutting operations of multi-channel electromagnetic wires. Summary of the Invention

The output end of the motor 7 is fixedly connected to the other end of the feeding shaft 5. The motor 7 is fixedly connected to one of the fixed plates 2.

[0032] The cooling and shaping mechanism also includes a double-segment screw 23. Two movable plates 25 are threaded on the outside of the double-segment screw 23. The two movable plates 25 are fixedly connected to the first cooling plate 26 and the second cooling plate 28, respectively. A second motor 24 is provided at one end of the double-segment screw 23. The output end of the second motor 24 is fixedly connected to the double-segment screw 23. A copper wire 8 is sleeved between the first cooling plate 26 and the second cooling plate 28.

[0033] The cooling and shaping mechanism also includes a push rod motor 2 14 fixed on the top of the worktable 1. A rack 15 is fixed to the output end of the push rod motor 2 14. Multiple gears 2 13 are meshed on the top of the rack 15. The gears 2 13 are fixed to one end of the push rod motor 1 12.

[0034] The expansion and contraction length precision control mechanism also includes a fixed plate 2 11 fixed on the top of the worktable 1, multiple push rod motors 12 rotatably connected inside the fixed plate 2 11, the output end of the push rod motors 12 is fixed to the housing 16, the double-segment screw 23 is rotatably connected inside the housing 16, and the motor 24 is fixed on the top of the housing 16. The movable plate 25 is fitted inside the housing 16; A fixed plate 21 is provided between the two movable plates 25. The laser distance sensor 22 is fixedly connected to the fixed plate 21, and the fixed plate 21 is fixedly connected to the housing 16.

[0035] Two connecting plates 17 are fixed on one side of the housing 16, and a frame 18 is fixed on one side of the two connecting plates 17. Push rod motors 19 are fixed on the top and bottom of the frame 18. Blades 20 are fixed on the output end of the push rod motors 19, and the blades of the two blades 20 are facing each other.

[0036] Working principle: When the motor 7 starts, it drives two feeding shafts 5 to rotate synchronously in opposite directions through a pair of meshing gears 6. The copper wire 8 is clamped by the friction between the feeding shaft 5 and the copper wire 8 and is conveyed into the stress relief mechanism at a uniform and constant speed. The device is equipped with multiple sets of one-to-one corresponding feeding shafts 5 and wire drums 3, which can realize the parallel and synchronous feeding of multiple copper wires and ensure that the feeding speed and feed amount of each channel are consistent.

[0037] After the copper wire 8 enters the internal channel of the spool 3, the heater 4, which is fixed to the outside of the spool 3, is energized to generate heat. The heat is evenly conducted to the copper wire 8 inside through the spool 3 wall. After the copper material is heated, the yield strength is greatly reduced, and the residual bending internal stress formed during the winding and storage of the wire is gradually released. Under the rigid constraint of the straight channel on the inner wall of the spool 3, the originally bent copper wire 8 is forced to straighten, eliminating the problem of the copper wire springing back and bending due to residual stress after cutting from the root.

[0038] The high-temperature copper wire 8, having completed stress release, exits from the coil 3 and enters the cooling channel formed by the cooling plate 26 and the cooling plate 28. The copper wire 8 is supported by the cooling plate 27 and is in close contact with the cooling plate 27. The cooling plate 27, fixed inside the cooling plate 26, and the cooling plate 20, fixed inside the cooling plate 28, are simultaneously energized and cooled. Rapid cooling is achieved through heat exchange between the cooling plate 27 and the copper wire 8, allowing the copper wire 8 to cool down to room temperature while maintaining its straight shape. This permanently fixes the straightened shape and allows the copper wire 8 to completely shrink back to its standard room temperature state due to thermal expansion.

[0039] Subsequently, push rod motor 14 drives rack 15 to move horizontally along worktable 1. Through the meshing transmission between rack 15 and gear 13, push rod motor 12 rotates inside fixed plate 11, thereby causing the housing 16 and the entire internal cooling plate assembly to flip over, so that cooling plate 26 and cooling plate 28 exchange positions. During the position exchange, the finished copper wire 8 that has been cut loses its support and falls from the gap between the two cooling plates onto the conveyor belt 9 below, where it is continuously conveyed outward by the conveyor belt 9.

[0040] After the position exchange is completed, the second cooling plate 10 is positioned below the copper wire 8. The second motor 24 drives the double-segment screw 23 to rotate, causing the two moving plates 25 to move upwards simultaneously. This allows the first cooling plate 27 and the second cooling plate 10 to move upwards synchronously, ultimately bringing the second cooling plate 10 into close contact with the lower surface of the newly fed copper wire 8, continuously cooling and shaping the next section of copper wire 8 to be processed. By using alternating contact cooling with the dual cooling plates, the waiting period for repeated heating and cooling of a single cooling plate is eliminated, effectively shortening the cooling time of a single section of wire. This enables continuous processing of the copper wire 8, significantly improving production efficiency and cooling consistency.

[0041] To address the issue of unstable wire-forward position affecting cutting accuracy due to thermal expansion and contraction during continuous processing of the same copper wire 8, a laser distance sensor 22 fixed on the fixing plate 21 collects axial position data of the copper wire 8 end in real time, accurately capturing the axial expansion and contraction displacement of the copper wire 8 caused by thermal expansion and contraction. When a deviation in the fixed-length cutting position is detected due to thermal expansion and contraction of the copper wire 8, the control system sends a command to the push rod motor 12. The output of the push rod motor 12 drives the housing 16 and the cooling and shaping mechanism and cutting mechanism mounted on the housing 16 to translate along the axial direction of the copper wire 8, directly offsetting the length error caused by thermal expansion and contraction, and real-time compensation to keep the effective cutting length of the copper wire 8 on the cooling plate stable.

[0042] Once the length compensation is in place, the push rod motors 19 at the top and bottom of the frame 18 are immediately activated to output thrust synchronously, driving the two blades 20 with opposite blades to move towards each other, cutting the copper wire 8 in a vertical cutting manner.

[0043] After being cut, the finished wire falls onto the conveyor belt 9 and is continuously conveyed outward by the conveyor belt 9.

[0044] The entire device is equipped with multiple independent and synchronously operating processing channels arranged in parallel along the horizontal direction. Each channel is equipped with independent feeding, heating and straightening, cooling and shaping, length compensation and cutting units. The units work together synchronously to complete the continuous processing of multiple electromagnetic wires at the same time, which greatly improves the overall processing efficiency while ensuring processing accuracy and wire straightness.
