Description

TECHNICAL FIELD

[0002] Electromagnetic heating is favored by people due to its energy saving, environmental protection, safety and high efficiency, and therefore, a large number of household kitchen appliances such as induction cookers for heating in a magnetic induction mode appear in the market.

[0003] In order to make the pot body suitable for electromagnetic heating, a layer or multiple layers of magnetic conductive material are generally coated on the bottom of the pot to form a bottomed pot, so that non-magnetic metal pots such as aluminum pots can also be used on the induction cooker. In the production process, the bottom sheet (such as stainless steel material) is connected to the pot sheet by cold stamping, and then the whole pot body is formed. For the positioning of the pot sheet, the existing technology such as the "centering positioning mechanism for automatic production" disclosed in Chinese patent CN104525771B and the "feeding table" disclosed in Chinese patent CN204588085U can achieve its feeding positioning. The bottom sheet generally has two types, one without holes in the middle and the other with holes in the middle for users to punch out the brand logo. For the positioning of the bottom sheet, since the bottom sheet is cut by a punch, the thickness is not large, and a honeycomb groove is generally punched out, which deforms in the production process. The existing positioning equipment cannot achieve automatic positioning of the bottom sheet, and manual feeding is required before stamping during the bottoming process of the pot sheet, which cannot realize automatic bottoming, has low production efficiency and has safety hazards.

[0004] For the automatic positioning of the bottom sheet with holes in the middle, the present application provides a cold bottoming automatic equipment for bottomed pots, which is provided with a bottoming pot cold bottoming automatic equipment for automatically positioning the bottom sheet with holes in the middle.
