Description

Technical Field

[0002] An induction cooker, also known as an electromagnetic stove, is a product of the modern kitchen revolution. It can directly generate heat at the bottom of the pot without an open flame or conductive heating, so the thermal efficiency has been greatly improved. It is a highly efficient and energy-saving kitchen utensil, which is completely different from all traditional kitchen utensils with or without fire conductive heating.

[0003] The heating ring of an induction cooker is usually composed of pure copper, copper-clad aluminum or pure aluminum, and is in a ring shape. During processing, it usually needs to be bent, and then the two ends of the bent ring tube are welded together to form an integral structure. For example, Chinese Patent (CN218362858U) discloses a welding device for switching heating rings of an induction cooker, which records this content. In traditional technology, manual bending is used, which is time-consuming and laborious. Later, a device is used for bending, but the two ends of the bent ring tube often appear at different heights, resulting in subsequent inability to weld, and still need to be adjusted by staff. In addition, the heating ring formed after welding is not a perfect ring shape and has "deformities", which is difficult to meet the needs of the staff. Summary of the Invention
