[0013] By adopting the above technical solution, when the moving mold approaches the fixed mold, the transmission linkage receives the power of the moving mold and drives the pusher plate to slide away from the fixed mold. The moving mold punches the silicon steel sheet on the fixed mold to form stator laminations. When the moving mold moves away from the fixed mold, the transmission linkage receives the power of the moving mold and drives the pusher plate to slide towards the fixed mold. The pusher plate surface abuts against the stator laminations on the fixed mold and drives the stator laminations away from the fixed mold, realizing automatic unloading of stator laminations. There is no need for workers to pick up the stator laminations on the fixed mold one by one, thereby reducing the workload of workers and improving the production efficiency of stator laminations.

[0016] Optionally, the worktable is connected to a drive piston, and a sealed cavity is provided on the worktable for the drive piston to slide. The sliding direction of the drive piston and the sliding direction of the positioning plate are parallel to each other. The fixed mold is located between the sealed cavity and the push plate. A drive connecting rod is rotatably connected between the drive piston and the moving mold. When the moving mold slides away from the fixed mold, the drive connecting rod receives the power of the moving mold and drives the drive piston to slide closer to the moving mold. The drive piston drives the air in the sealed cavity to impact the stator laminations on the worktable.

When the drive piston slides towards the moving mold, it drives the airflow in the sealed cavity to impact the fan blades and drive the transmission fan to rotate. The transmission assembly receives the power of the transmission fan and drives the multiple cooling fans to rotate.

[0019] By adopting the above technical solution, when the moving mold slides away from the fixed mold, the drive linkage receives the power of the moving mold and drives the drive piston to slide closer to the moving mold. This causes the airflow in the sealed cavity to impact the drive fan blades and drive the drive fan to rotate. The transmission component receives the power of the drive fan and drives multiple cooling fans to rotate. The air outlet of the cooling fans faces the stator laminations, achieving stable cooling of the stator laminations. No external power equipment is needed to drive the cooling fans to rotate, reducing energy consumption and embodying the concept of energy saving.

[0020] Optionally, the transmission assembly includes a driving bevel gear, a driven bevel gear, a transmission rod, multiple first transmission bevel gears, and multiple second transmission bevel gears. One end of the transmission rod along its axial direction is rotatably connected to a positioning plate, and the other end of the transmission rod along its axial direction is coaxially connected to the driven bevel gear.

[0021] By adopting the above technical solution, when the fixed mold slides away from the moving mold, the limiting effect of the fixed mold on the positioning plate disappears. The elastic force of the elastic component drives the positioning plate to slide away from the worktable. The air outlets of multiple cooling fans face the stator laminations. At the same time, the driven bevel gear meshes with the driving bevel gear, and the driving linkage receives the power of the moving mold and drives the driving piston to slide closer to the moving mold. The driving piston drives the air in the sealed cavity to impact the fan blades of the transmission fan. The rotation of the transmission fan drives the driven bevel gear and the driving bevel gear to rotate, which drives the transmission rod to rotate. The first transmission bevel gear meshes with the second transmission bevel gear, thereby driving multiple cooling fans to rotate. The cooling fans drive the airflow to impact the stator laminations.

[0029] Stator laminations are cooled by multiple cooling fans driving airflow to impact the stator laminations on the stator die.

[0030] By adopting the above technical solution, the silicon steel coil is placed on the positioning mechanism, the silicon steel sheet on the silicon steel coil is placed on the fixed mold, the moving mold stamps the silicon steel sheet on the fixed mold to form stator laminations, and the cooling fan drives the airflow to impact the stator laminations, thereby cooling the stator laminations and making them less prone to deformation due to high temperatures, thus improving the production quality of electronic laminations.

The support part 11 has sliding cavities 112 for the positioning plates 41 to slide. The sliding direction of the positioning plates 41 is parallel to the axis of the connecting part 12. The two sliding cavities 112 are located on both sides of the width direction of the support part 11, and the fixed mold 2 is located between the two sliding cavities 112. In this embodiment, the sliding cavity 112 is a strip cavity. The length direction of the sliding cavity 112 is parallel to the length direction of the support part 11. An elastic member 5 is connected between the inner wall of the sliding cavity 112 and the positioning plate 41. The elastic member 5 can be a compression spring or a tension spring. In this embodiment, the elastic member 5 is a compression spring and has a certain deformation capacity.

[0042] Reference Figure 1 and Figure 2 The elastic force direction of the elastic member 5 is parallel to the sliding direction of the positioning plate 41. The elastic member 5 has the elastic force to drive the positioning plate 41 to slide closer to the moving mold 3, and the positioning plate 41 tends to protrude from the support part 11. Multiple cooling fans 42 are evenly connected at intervals on the side of the positioning plate 41 facing the fixed mold 2, and the air outlet of the cooling fans 42 faces the stator lamination of the fixed mold 2.

When the moving die 3 presses the silicon steel sheet on the fixed die 2 to form a stator lamination, the moving die 3 slides away from the fixed die 2. The transmission linkage 7 receives the power of the moving die 3 and drives the pusher plate 6 to slide closer to the fixed die 2. The pusher plate 6 abuts against the stator lamination on the fixed die 2 and drives the stator lamination to slide away from the fixed die 2, thereby realizing the automatic unloading of the stator lamination on the fixed die 2. This eliminates the need for workers to pick up the stator laminations on the fixed die 2 one by one, reducing the workload of workers and improving the production efficiency of stator laminations.

The sliding direction of the drive piston 9 is parallel to the sliding direction of the moving mold 3. The sealing cavity 114 is located on the side of the fixed mold 2 away from the push plate 6. The sealing cavity 114 is a strip-shaped cavity. The length direction of the sealing cavity 114 is parallel to the width direction of the support part 11. A drive connecting rod 10 is rotatably connected between the drive piston 9 and the moving mold 3. The number of drive connecting rods 10 can be one or two.

The drive piston 9 drives the air in the sealed cavity 114 to impact the stator laminations on the support part 11, thereby cooling the stator laminations and further improving the cooling efficiency of the stator laminations.

[0047] Reference Figure 2A transmission device 13 is connected to the support part 11. In this embodiment, there are two transmission devices 13, and each transmission device 13 corresponds to a positioning plate 41. The transmission device 13 is used to receive airflow in the sealed cavity 114 and drive the cooling fan 42 to rotate.

[0049] Reference Figure 1 and Figure 2 When the drive piston 9 slides towards the moving mold 3, it drives the airflow in the sealed cavity 114 to be discharged. The airflow impacts some of the fan blades of the transmission fan 131 and drives the transmission fan 131 to rotate. The driven bevel gear 1322 meshes with the driving bevel gear 1321, driving the transmission rod 1323 to rotate, which in turn drives multiple cooling fans 42 to rotate. The cooling fans 42 drive the airflow to impact the stator laminations. The stator laminations transfer heat energy to the airflow, thereby cooling the stator laminations and making them less prone to overheating and deformation, thus improving the production efficiency of the stator laminations.

[0050] Reference Figure 2 A material rack 14 is welded and fixed to the side of the support part 11 near the sealing cavity 114. The material rack 14 is used for the stacking of stator laminations. When the pusher plate 6 abuts against the stator laminations on the die 2 and drives the stator laminations to slide towards the sealing cavity 114, the stator laminations are stacked above the sealing cavity 114. Adjacent stator laminations are squeezed against each other and driven into the end face of the material rack 14, thus realizing the storage of stator laminations on the material rack 14.

[0051] The implementation principle of the anti-temperature rise device for stator lamination of flat copper wire motor of new energy vehicle in this application embodiment is as follows: the silicon steel sheet passes through the positioning groove 411 on the two positioning plates 41 in sequence. The silicon steel sheet is limited above the fixed mold 2. The moving mold 3 slides towards the fixed mold 2. The moving mold 3 abuts against the positioning plate 41 and drives the positioning plate 41 to slide towards the support part 11. The silicon steel sheet abuts against the side of the fixed mold 2 facing the moving mold 3. The moving mold 3 punches the silicon steel sheet on the fixed mold 2 to form the stator lamination. The moving mold 3 slides away from the fixed mold 2. The limiting effect of the moving mold 3 on the positioning plate 41 disappears. The elastic element 5 elastically drives the positioning plate 41 to slide away from the support part 11. The exhaust end of the cooling fan 42 faces the stator lamination on the fixed mold 2. At the same time, the driven bevel gear 1322 meshes with the driving fan. The bevel gear 1321 drives the connecting rod 10 to receive power from the moving mold 3 and drive the driving piston 9 to slide closer to the moving mold 3, causing the airflow in the sealed cavity 114 to be discharged. The airflow impacts part of the fan blades of the transmission fan 131 and drives the transmission fan 131 to rotate. The driven bevel gear 1322 meshes with the driving bevel gear 1321, driving the transmission rod 1323 to rotate, which in turn drives multiple cooling fans 42 to rotate. The cooling fans 42 drive the airflow to impact the stator laminations, and the stator laminations transfer heat to the airflow, thus cooling the stator laminations. The cooling fans 42 drive the airflow to impact the stator laminations on the fixed mold 2, and the stator laminations transfer heat to the airflow, thus cooling the stator laminations and preventing them from overheating and deforming, thereby improving the production quality of the stator laminations.
