Abstract

The invention discloses a pot cover manufacturing method. The pot cover manufacturing method includes steps of forming a steel body after steps of strip butt welding, rolloff and roller forming, rolling an edge wrapping ring and the steel body, placing glass into the edge wrapping ring, and then rolling the glass to form a pot cover. The pot cover manufacturing method is few in procedures, material utilization rate is improved and the problem that water vapor in the pot cover drops into food is solved.

Description

technical field [0001] The invention relates to a manufacturing method of a pot cover. Background technique [0002] The half-glass covers sold on the market are all formed by stretching the steel body with a circular steel material, and then punching off the excess steel material at the position of the glass in the middle. There are many production processes and the utilization rate of materials is low; the water vapor in the cover is easy to drip into the dishes, affecting the taste of the food. Contents of the invention [0003] In order to overcome the disadvantages of many production processes, low material utilization rate and easy drop of water vapor in the cover to the dishes in the existing half-glass pot cover manufacturing process, which affects the taste of food, the invention provides a method for manufacturing a pot cover. [0004] The technical scheme adopted in the present invention is: [0005] The manufacturing method of the pot cover is characterized i...
