Problems solved by technology

At present, stainless steel sinks have single-slot, double-slot, three-slot and other structures. When making double-slot and three-slot water tanks, due to the limitations of process conditions and equipment conditions, they are stretched out one by one with single tanks, and then welded. The process is welded into a double-slot or three-slot type according to the needs. The welding process first increases the processing steps of the water tank and increases the material consumption, thereby greatly increasing the production cost of the water tank; secondly, it is difficult to guarantee the welding quality. Desoldering and cracks are unavoidable, which will inevitably affect the overall quality and service life of the sink
Moreover, there is no relevant literature record found in the existing patent literature

Embodiment Construction

[0041] The overall stretching process of the present invention will be further described in detail below in conjunction with the above-mentioned drawings and taking the model of the mother-in-law double groove as 28211 as an example. The process is as follows:

[0042] (1) Cutting material: send the stainless steel grade SUS304 and the specification of 1×1219×C coil material into the shearing machine and cut it into the required expansion size of the water tank ( figure 1 ), in order to save material, adopt paired shearing;

[0043] (2) Corner cutting: Send the flat material after blanking into the shearing machine, and cut the excess material at the four corners ( figure 2 ), to prevent wrinkling in the next stretching process;

[0044] (3) Stretching for the first time: Send the flat material after cutting the angle into the 630T hydraulic press. In order to prevent the material flow of individual parts and prevent the phenomenon of pulling cracks, the stretching ribs 3 mu...

Abstract

The invention is a stainless steel double-tanked (three-tanked) water tank stretching technique, including the working procedures such as batching, shearing angle, first stretching, shearing side, washing, annealing, second stretching, cutting side, punching hole, surface processing, etc. The water tank made by the working procedures forms a through structure without welding, reducing production cost and avoiding the problems of water leakage and of affecting fastness, thus heightening the whole quality and service life of the water tank.

Description

technical field [0001] The invention relates to an integral stretching process of kitchen utensils, especially stainless steel sinks for washing. Background technique [0002] With the improvement of people's living standards, a stainless steel sink with beautiful appearance, smooth shape, light weight, easy to scrub and not easy to damage is the direction to replace ceramic sinks, and has entered thousands of households and is more and more popular. At present, stainless steel sinks have single-slot, double-slot, three-slot and other structures. When making double-slot and three-slot water tanks, due to the limitations of process conditions and equipment conditions, they are stretched out one by one with single tanks, and then welded. The process is welded into a double-slot or three-slot type according to the needs. The welding process first increases the processing steps of the water tank and increases the material consumption, thereby greatly increasing the production co...
