Problems solved by technology

However, the depth of the water tank stretched by this scheme is only 150mm, and everything is for the purpose of achieving a water tank with a depth of 150mm. It is impossible to achieve a deeper size by using the processing technology reported in the literature.
Experience has proved that a sink with a depth of only 150mm is of no practical significance, because people hate the phenomenon of water splashing during the washing process

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) The first stretching: 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 must be reaso...

Abstract

A multi-groove overall stretching process for a stainless steel sink, the process includes blanking, corner cutting, first stretching, edge trimming, cleaning, annealing, second stretching, edge trimming, punching, cleaning, surface treatment, etc. Processing procedure. The tank body of the stainless steel sink manufactured through this process is a one-piece structure without welding, and the groove depth can reach 180-250mm, which not only overcomes the defects of many processes and material costs caused by welding, but also reduces the production cost for the enterprise. At the same time, it also avoids the water leakage and fastness problems caused by missing welding and desoldering that are easy to occur during the welding process, thereby improving the overall quality and service life of the sink, and making the appearance and depth of the one-piece stainless steel sink more catering to modern times. It has better price advantage in market competition and creates better economic benefits for enterprises.

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...
