Claims

1. A device for automatically rounding a magnetic ring, characterized in that: The assembly includes a lower die base, a lower backing plate on the lower die base, a lower template on the lower backing plate, an upper die base, an upper backing plate on the upper die base, an upper clamping plate on the upper backing plate, and a stripper plate on the upper clamping plate. The upper die base is linked to a stamping machine. A stamping space is formed between the lower template and the stripper plate, allowing the sheet metal to pass through. The lower template is provided with a chamfering mechanism, a shearing mechanism, a cutting mechanism, and a rounding mechanism along the length of the sheet metal. The rounding mechanism includes a support slider slidably mounted on the lower template, a shaping shaft linked to the support slider along the width of the sheet metal, a U-shaped bending punch, and a circular bending punch. A nitrogen spring is provided between the support slider and the lower die base. The U-shaped bending punch and the circular bending punch are linked to the upper die base. The lower template is provided with U-shaped bending dies and circular bending dies arranged side by side along the axial direction of the shaping shaft, which cooperate with the U-shaped bending punch and the circular bending punch.

2. The automatic round winding device for magnetic conducting ring according to claim 1, characterized in that: The lower template is provided with a slider ejection mechanism on the side corresponding to the U-shaped bending die to eject the magnetic ring from the shaping shaft. The slider ejection mechanism includes a guide block and a guide plate on the lower template, a slider slidably disposed within the guide plate, two push rods, and a drive block. A compression spring is provided between the slider and the guide plate. The two push rods are linked on the slider and used to eject the magnetic ring from the shaping shaft. The drive block is linked with the upper mold base. When the upper mold base performs the mold closing action, the upper mold base causes the drive block to slide on the guide plate and compress the compression spring. When the upper mold base performs the mold opening action, the slider loses the driving force of the drive block, and the elastic force of the compression spring causes the slider to drive the two push rods to eject the magnetic ring from the shaping shaft.

3. The automatic round winding device for magnetic conducting ring according to claim 2, characterized in that: The drive block has a drive ramp on the side facing the compression spring, and the slider has a load-bearing ramp that cooperates with the drive ramp. When the upper mold base performs the mold closing action, the upper mold base causes the drive ramp of the drive block to abut against the load-bearing ramp of the slider, thus forming a linkage between the slider and the drive block.

4. The automatic round winding device for magnetic conducting ring according to claim 2 or 3, characterized in that: The guide block is provided with two guide holes for two push rods to pass through, and the guide block is provided with two guide grooves that communicate with the two guide holes. The pushing part of one end of the two push rods passes through the two guide grooves and the two guide holes in sequence and extends out of the guide block.

5. The automatic round winding device for magnetic conducting ring according to claim 2 or 3, characterized in that: The guide plate is provided with a sliding groove, and the slider has a protrusion that is slidably disposed in the sliding groove.

6. The automatic magnet ring coiling device according to claim 1, characterized in that: The lower template is provided with a receiving groove for placing the support slider. Sliding guide grooves are provided on both sides of the receiving groove. The support slider has two guide protrusions that are slidably disposed in the sliding guide grooves on both sides.

7. The automatic magnet ring coiling device according to claim 1, characterized in that: The chamfering mechanism includes two chamfering punches and a chamfering die set on the lower template. The two chamfering punches are linked and cooperate with the upper die base. The driving force of the upper die base causes the two chamfering punches and the chamfering die to close together, and is used to chamfer both sides of the plate.

8. The automatic magnet ring coiling device according to claim 1, characterized in that: The cutting mechanism includes two width cutting punches and a cutting die set on the lower template. The two width cutting punches are linked and cooperate with the upper die base. The driving force of the upper die base causes the two width cutting punches and the cutting die to close together, and is used to cut the width of the sheet metal.

9. The automatic magnet ring coiling device according to claim 1, characterized in that: The cutting mechanism includes an upper cutting die and a lower cutting die set on a lower template. The upper cutting die is linked with an upper die base. The driving force of the upper die base causes the upper cutting die and the lower cutting die to close together, and is used to cut the sheet material.

10. The automatic magnet ring coiling device according to claim 1, characterized in that: The lower mold base and the lower template are respectively provided with finished product dropping holes at the tail of the shaping shaft.
