Description
Technical Field
[0001] This invention relates to the field of magneto core manufacturing technology, and in particular to a continuous stamping die in-mold welding device for magneto cores. Background Technology
[0002] Currently, magneto cores, as core electromagnetic components of gasoline engines, motorcycles, and general-purpose power machinery, typically use high-permeability strip silicon steel as the main processing material. Their overall structure is formed by welding and bonding multiple identical ring-shaped silicon steel sheets together. In actual manufacturing, the conventional process involves continuously feeding and conveying the entire roll of strip silicon steel material, then sequentially blanking and punching it through specialized stamping equipment to produce uniformly sized and regularly shaped single cores. These single cores are then precisely stacked layer by layer. The individual iron cores are stacked together to ensure they fit and align. Finally, the outer ring of the stacked iron core is fixed by multi-point welding using spot welding, laser welding, and other welding methods, thus binding the multiple individual iron cores into a single integrated structure. This meets the electromagnetic performance, structural strength, and coaxiality requirements of the magneto during assembly and use. The forming quality of the magneto iron core directly determines the working efficiency, operational stability, and service life of the magneto. The stamping precision, stacking flatness, and welding strength of the strip silicon steel raw material are key process indicators for controlling the quality of the finished iron core. Currently, the industry has a large demand for magneto iron core production and generally pursues large-scale continuous processing. This places higher demands on the continuity of processing steps, the accuracy of forming dimensions, welding sealing, and the yield rate of finished products. However, the strip silicon steel raw material itself is thin and easily deformed by heat. Under the heat of continuous stamping and welding, defects such as warping, misalignment, and uneven stacking are prone to occur. This also places stringent requirements on the structural rationality, heat dissipation capacity, and process integration of processing equipment.
[0003] However, traditional processing methods mostly separate the stamping, lamination, and welding processes. After the raw materials are stamped and sliced, they need to be transferred to independent welding equipment for lamination and welding. The process is interrupted and continuous in-mold processing cannot be achieved. Existing equipment cannot directly weld in-mold after stamping and lamination. The processing process is not continuous. In addition, the iron core will generate a lot of heat during the stamping and welding process. The processing area is in a high-temperature state for a long time. This not only easily causes thermal deformation of the stamped single iron core, resulting in uneven lamination gaps, but also easily causes oxidation black spots at the welding position, affecting the welding sealing and resulting in a low production yield. To address the aforementioned problems, this application proposes a continuous stamping die in-mold welding device for magneto cores. Summary of the Invention

[0022] (III) Beneficial Effects In summary, this application includes at least one of the following beneficial technical effects: 1. A continuous stamping die welding device for magneto cores, which, by setting a ring-shaped welding assembly on the outside of the die, can directly complete the welding operation in the die after the core is stamped and stacked, realizing continuous processing of strip raw material feeding, stamping and stacking, and in-die welding. At the same time, the ring-shaped array of welding points can uniformly weld and fix the outside of the core, making the multi-layer iron chip stacked tightly, avoiding delamination and loosening of the core in later use, and improving the overall structural consistency and forming stability of the core.
[0023] 2. A continuous stamping die welding device for a magneto core, which achieves the mechanical linkage between stamping and heat dissipation by setting up a stamping assembly and a heat dissipation assembly. The power of the reciprocating motion of the stamping head drives the hinge rod, push-pull rod and connecting rod to perform mechanical transmission, thereby completing the air cooling of the processing area. This solves the problem of the separation between stamping and welding processes, simplifies the process flow, ensures uniform welding of the core, and improves the overall structural strength and forming quality of the core.
[0024] 3. A continuous stamping die welding device for magneto iron cores, which transmits power through a toothed belt to drive the feeding roller to rotate synchronously, so that the equipment can automatically complete the feeding of strip material while completing the stamping and heat dissipation. This keeps the feeding, stamping and heat dissipation actions synchronized, avoiding problems such as action deviation and feeding misalignment caused by independent driving, accurately controlling the amount of raw material fed, and ensuring that the stamping specifications of each iron core are consistent. This solves the problems of uneven feeding and poor processing synchronization of traditional equipment, and improves the continuity of equipment processing. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.
[0028] Example: A continuous stamping die in-mold welding device for a magneto core, referring to... Figure 1-3 The system includes a base 1, which is made of high-strength cast iron and has been precision ground to ensure the horizontal and vertical alignment of the upper components. This provides stable and reliable support for continuous stamping, in-mold welding, automatic feeding, heat dissipation and cooling, and unloading. A bracket 2 is fixedly connected to the upper surface of the base 1. The bracket 2 has a vertical symmetrical structure. A stamping assembly is installed in the middle of the bracket 2. The stamping assembly includes a motor 3, a threaded sleeve 4, a reciprocating threaded rod 5, and a stamping head 6. The side surface of the motor 3 is fixedly connected to the bracket 2, and the output end of the motor 3 is fixedly connected to the threaded sleeve 4. The inner wall of the threaded sleeve 4 is threadedly connected to the reciprocating threaded rod 5, and the lower surface of the reciprocating threaded rod 5 is fixedly connected to the stamping head 6. A mold 7 is set below the stamping assembly. The bottom shape of the stamping head 6 matches the cavity of the mold 7 to ensure a smooth stamping process. The mold 7 has four annularly arranged welding grooves 8 on its side, with the positions of the welding grooves 8 corresponding to the welding points of the iron core. Welding components are provided on the outer sides of each of the four welding grooves 8. These components include a tension rod 9, a slider 10, a vertical electric telescopic rod 11, and a laser welding head 12. The lower end of the tension rod 9 is hinged to the slider 10, the upper surface of the slider 10 is fixedly connected to the vertical electric telescopic rod 11, the output end of the vertical electric telescopic rod 11 is fixedly connected to the laser welding head 12, and the upper end of the tension rod 9 is hinged to the stamping head 6. Through the linkage between the stamping head 6, the tension rod 9, the slider 10, and the laser welding head 12, when the stamping head 6 moves downwards… During the stamping and blanking process, the tension rod 9 moves downward and pushes the slider 10 to move inward in the horizontal direction, so that the laser welding head 12 extends into the weld groove 8 and performs ring welding operation at the same time as the iron core is stamped and stacked; when the stamping head 6 moves upward and resets, the tension rod 9 pulls the slider 10 to move outward, and the laser welding head 12 exits the working area, realizing the synchronous and sequential coordination of stamping and welding. This can ensure that the welding action and the stamping process are highly coordinated, and can also complete the welding of multi-layer iron chips at the moment of stamping and compaction, greatly improving the tightness of iron core stacking and welding firmness, and avoiding problems such as delamination, loosening, and weld misalignment of the iron core. A heat dissipation assembly is provided on the base 1. The heat dissipation assembly includes a first support rod 14, a first rotating rod 15, and a fan blade 16. The lower end of the first support rod 14 is fixedly connected to the base 1. The side surface of the first rotating rod 15 is rotatably connected to the first support rod 14. The fan blade 16 is sleeved and fixedly connected to the side surface of the first rotating rod 15. By setting up the heat dissipation assembly, the fan blade 16 is rotated by the first rotating rod 15 to generate airflow. Through continuous airflow, the extrusion heat generated during the stamping process and the high temperature heat generated during the welding process can be quickly removed. This avoids problems such as deformation, annealing, and decreased hardness of the mold 7, stamping head 6, and iron core due to excessive temperature. At the same time, it prevents uneven stacking of the iron core and oxidation and blackening of the weld.
[0029] Reference Figure 2 The upper surface of the base 1 is provided with four circularly distributed grooves 13. The lower surface of the slider 10 is in contact with the grooves 13. By setting the grooves 13, the bottom of the slider 10 can slide along the inner wall of the grooves 13, so that the laser welding head 12 moves more smoothly into the welding groove 8 and the welding position is more accurate.
[0030] Reference Figure 2 , Figure 4 and Figure 6One end of the first rotating rod 15 is fixedly connected to a connecting rod 17. The end of the connecting rod 17 away from the first rotating rod 15 is rotatably connected to a push-pull rod 18. The end of the push-pull rod 18 away from the connecting rod 17 is hinged to a hinge rod 19. The end of the hinge rod 19 away from the push-pull rod 18 is fixedly connected to the stamping head 6. By setting the connecting rod 17, the push-pull rod 18 and the hinge rod 19, the reciprocating stamping of the stamping head 6 drives the hinge rod 19 to move linearly up and down. The hinge rod 19 drives the push-pull rod 18 to repeatedly push and pull the connecting rod 17, so that the end of the connecting rod 17 away from the push-pull rod 18 drives the first rotating rod 15 to rotate, thereby providing power for the heat dissipation component and realizing the linkage effect of stamping and heat dissipation.
[0031] Reference Figure 4-6 The base 1 is fixedly connected to a second support rod 20, on which a feeding assembly is installed. The feeding assembly includes an upper feeding roller 21 and a lower feeding roller 22. Both ends of the upper feeding roller 21 are rotatably connected to the second support rod 20. The lower feeding roller 22 is located directly below the upper feeding roller 21. Gears 23 are fitted and fixedly connected to the side surfaces of both the upper and lower feeding rollers 21 and 22. The two gears 23 mesh with each other. By setting up the feeding assembly, the rotation of the lower feeding roller 22 drives the lower feeding roller 22 to rotate synchronously through the gears 23. At this time, the strip material held between the lower feeding roller 22 and the gears 23 is transported between the stamping head 6 and the mold 7, realizing the feeding function. The end of the lower feeding roller 22 away from the second support rod 20 is fitted and fixedly connected to a gear. A toothed pulley 24 is provided, with a toothed belt 25 meshing with its side surface. A toothed pulley 26 is meshed with the end of the toothed belt 25 away from the toothed pulley 24. The inner wall of the toothed pulley 26 is fixedly connected to the rotating rod 15. By setting up the toothed belt 25, the toothed pulley 26, and the electric telescopic rod 27, the rotation of the rotating rod 15 drives the toothed pulley 26 to rotate. The toothed pulley 26 transmits power to the toothed pulley 24 through the toothed belt 25. The toothed pulley 24 drives the lower feeding roller 22 to rotate. The lower feeding roller 22 drives two gears 23 to rotate. At this time, the upper feeding roller 21 and the lower feeding roller 22 rotate synchronously in opposite directions to feed material inward, thereby realizing the synchronous linkage of heat dissipation and feeding.
[0032] Reference Figure 1 and Figure 3The mold 7 is equipped with a No. 3 electric telescopic rod 27. The lower surface of the No. 3 electric telescopic rod 27 is fixedly connected to a slide plate 28. The upper surface of the base 1 is fixedly connected to a cylinder 29. The output end of the cylinder 29 is fixedly connected to the slide plate 28. After the iron core completes multi-layer stamping and stacking and ring welding, the cylinder 29 is activated, pulling the slide plate 28 outward to fully expose the bottom of the iron core. Then the No. 3 electric telescopic rod 27 is activated, extending upward to smoothly push the formed iron core out of the mold 7, realizing automated unloading. The whole unloading action is smooth and has low impact force, and will not damage the surface of the iron core and the weld.
[0033] Reference Figure 1 and Figure 7 A sleeve 30 is fixedly connected to the upper surface of the base 1. A sliding column 31 is slidably connected inside the sleeve 30. The upper end of the sliding column 31 is fixedly connected to the bracket 2. A spring 32 is sleeved on the outside of the sliding column 31. One end of the spring 32 is fixedly connected to the bracket 2, and the other end of the spring 32 is fixedly connected to the sleeve 30. By setting four sleeves 30, sliding columns 31 and springs 32, the stamping head 6 can slide vertically and stably up and down, improving the stability and accuracy of the stamping process. A support platform 33 is fixedly connected to the upper surface of the base 1. A gap 34 is set inside the support platform 33. By setting the support platform 33, the strip material is passed through the gap 34, making the feeding and discharging of the material smoother and less prone to wrinkling and bending.
[0034] The implementation principle of this invention is as follows: First, the strip material is passed through the gap 34 inside the support 33 to keep the material flat during transport. The motor 3 drives the threaded sleeve 4 to rotate, and the reciprocating threaded rod 5 and the punch head 6 move vertically downwards through the threaded transmission. Together with the mold 7, the strip material is continuously punched, sliced and stacked. The sleeve 30, the sliding column 31 and the spring 32 cooperate with each other to ensure the smooth operation of the punch head 6 and improve the punching accuracy. During the reciprocating motion of the punch head 6, the hinge rod 19 moves vertically in sync, and pushes and pulls the connecting rod 17 through the push-pull rod 18, driving the first rotating rod 15 to rotate on the first support rod 14, driving the fan blade 16 to rotate and generate airflow to cool the punching and welding areas. At the same time, the first rotating rod 15 drives the second toothed pulley 26 to rotate, and the transmission is transmitted to the first toothed pulley 24 through the toothed belt 25, driving the lower part The feeding roller 22 rotates, and the meshing gear 23 drives the upper feeding roller 21 to rotate synchronously in opposite directions, realizing the synchronous linkage of feeding, stamping and heat dissipation. Before each core stacking, the vertical electric telescopic rod 11 adjusts the height of the laser welding head 12 in advance according to the position of the core. When the core is stacked, the pressing head 6 pushes the tension rod 9 to push the slider 10 to slide along the slide groove 13, so that the laser welding head 12 is aligned with the welding groove 8 on the side of the mold 7 for spot welding, thereby completing the ring-shaped multi-point welding operation of the core. Similarly, when the pressing head 6 rises, it drives the laser welding head 12 to retract. After the core stamping and welding process is completed, the cylinder 29 is started to pull the slide plate 28 to move, and then the No. 3 electric telescopic rod 27 is used to push the formed core out of the mold 7, completing the automated unloading. The entire process of feeding, stamping, welding, heat dissipation and unloading is completed in a continuous manner, realizing the continuous in-mold processing operation of the magneto core.
