Manufacturing technology of stainless steel box of dish-washing machine

Abstract

The invention relates to a manufacturing technology of a stainless steel box of a dish-washing machine. The manufacturing technology is designed to solve the problems that in existing similar products, the secondary stretching depth of water tanks is not large enough, and the overall machining process and procedure design is poor. The box is formed by machining a steel plate block through two times of stamping and stretching and one time of annealing. The manufacturing technology specifically comprises the following steps that a stainless steel coil steel plate is adopted as the steel plate block, and a blank of the steel plate block is cut by a plate shearing machine; the cut blank is put into a first stretching mold, and a trough obtained after stretching molding is put into an annealing furnace; after annealing finishes and the trough is cooled, the trough is put into a second stretching mold, and stretching molding is carried out for the second time; and finally, edge cutting, grinding, punching, strip welding, polishing, sand blasting, re-punching and bin drying are carried out, the finished trough and accessories are packaged and packed, and the box is obtained. The manufacturing technology can also be used for manufacturing the stainless steel box of the dish-washing machine with a water trough and is suitable for being used for machining the water trough of the stainless steel box of the dish-washing machine and the like.

Description

technical field [0001] The invention relates to a stainless steel box body, which is a manufacturing process of the stainless steel box body of a dishwasher. Background technique [0002] Dishwasher is a kind of equipment that automatically cleans bowls, chopsticks, plates, dishes and other tableware. According to the structure, it can be divided into two categories: box type and transmission type. Among them, the transmission type is mainly used in large catering places, and the box type is mainly used in family kitchen. Some existing household dishwashers are also combined with sinks for washing dishes and vegetables. The cabinets of such dishwashers are made of stainless steel and are opened by flip-top design. Among the similar products of this type of cabinet, some sinks are processed by secondary stretching to deepen the depth of the sink, so as to apply to a larger space capacity. For example, the application number 201110410104.6 disclosed in the Chinese patent lit...
