Description

technical field

[0001] The invention relates to a method for manufacturing a microwave oven cavity panel, in particular to a method for manufacturing a microwave oven cavity panel with excellent oil resistance, corrosion resistance and high temperature resistance, and belongs to the technical field of food machinery. Background technique

[0002] The oven cavity is a microwave resonant cavity, which is a space for converting microwave energy into heat energy to heat food. The oven cavity panel is made of metal plates coated with non-magnetic materials. There are ventilation holes on the left side and the top of the oven cavity. The microwave input into the oven cavity through the waveguide is reflected back and forth in the cavity wall. When the microwave propagates, it passes through the food, causing the molecules in the food to oscillate and rub, and then generate heat energy. , the food is evenly heated. When designing a microwave oven, the side length of the cavity is ...

Embodiment 1

[0017] The specific preparation process of the manufacturing method of the microwave oven cavity panel mentioned in the present invention is as follows:

[0018] a) Select the steel plate. The material of the steel plate is 45 steel. The preparation process includes casting, forging and rolling. The thickness of the selected steel plate is about 1.2mm; the above steel plate has good strength, plasticity and microwave reflection performance, and its price is lower than that of stainless steel. , which can effectively control the preparation cost;

[0019] b) Sheet metal processing, this process includes cutting, punching, folding, trimming, bending, deburring, etc. of steel plates; among them, the left and right panels in the furnace cavity and the corresponding parts of the upper panel need to punch out the cooling hole structure ;The left, right and lower panels are designed as an integrated structure, and the "concave" structure is made through the bending process; each stee...
