A production method of a bright stainless steel pot and its special mold

Abstract

The invention discloses a production method of a bright stainless steel pot. The production method comprises the steps that firstly, material selecting and cogging are conducted, and a stainless steel billet material with the thickness being 0.5-1.0 mm is obtained; secondly, stretching oil is smeared on the stainless steel billet material, the stainless steel billet material is covered with a PE protective film and then placed into a first stretching mould to be stabilized and positioned, and a first-time material pressing machine is started to conduct first-time stretching; thirdly, a stainless steel semi-finished product is taken, the PE protective film on the surface of the stainless steel semi-finished product is removed, the stretching oil on the surface is wiped out, and the stainless steel semi-finished product is sent into a hearth of a bright annealing furnace with the temperature being 1000 DEG C-1150 DEG C, and the heat preservation time is 18-25 minutes; and fourthly, the stainless steel semi-finished product is coated with stretching oil and placed in a second stretching mould, frame erecting and positioning are conducted, a layer of tensile film is sealed, and a second-time material pressing machine is started to conduct second-time stretching. According to the production method of the bright stainless steel pot, the tensile depth of the stainless steel pot is deepened, and the bright effect and the anticorrosion property of the surface of the stainless steel pot are effectively guaranteed.

Description

technical field [0001] The invention relates to a production method of stainless steel products, in particular to a production method of a bright stainless steel pot and a special mold thereof. Background technique [0002] Stainless steel has high hardness and significant cold work hardening effect, making it difficult to stretch parts. Therefore, most of the deep stainless steel frying pans are made by welding. For example, fryers for French fries, steaks, lamb chops, chicken, duck, lean meat and other foods in European and American countries have a standard capacity of 22-23 liters, and they are all welded. However, contact with moisture and seasoning and other salts at the welding point and high temperature will produce oxidation reaction, and then produce rust, which is extremely unfavorable to human health; Frame, no core, stamped with oil) the drawing depth can only reach a height of only 200-240mm, the surrounding R45mm, and the thickness is uneven, the bottom and ...

Problems solved by technology

However, contact with moisture and seasoning and other salts at the welding point and high temperature will produce oxidation reaction, and then produce rust, which is extremely unfavorable to human health; Frame, no core, stamped with oil) the drawing depth can only reach a height of only 200-240mm, the surrounding R45mm, and the thickness is uneven, the bottom and the R corner are easy to break, the product in use is easy to break, and the finished product Poor gloss, which seriously affects the recognition of oil residue in the fryer
