Problems solved by technology

[0003] In the forming process of the existing steel cylinder, the parts of the steel cylinder need to be quenched and tempered many times during processing, especially in the forming process of the steel cylinder, the steel plate used for forming needs to be tempered before stamping, which makes the steel plate easier to process Deformation to obtain a steel cylinder blank, and when the steel cylinder blank is shrinking, the steel cylinder blank must be heated again to facilitate its necking process, but the process of forming the steel cylinder produced in this way has many steps and is complicated. , so that the production efficiency of steel cylinders is low, and the qualified rate of steel cylinders made of steel cylinders due to large steel defects is low

Embodiment 1

[0016] A molding process for chemical steel cylinders, comprising the following steps:

[0017] 1) Steel plate material selection and processing for the production of steel cylinders. The specific steps are: A. Select steel plates that are not folded and perforated in line with the production steel cylinders and set aside; B. Put the steel plates selected in the specific step A into the tempering furnace and heat them to 600°C. After being kept warm for 2 hours, treat it to cool down naturally, obtain the steel plate after the tempering treatment, and set aside; C, the steel plate obtained by the step B tempering process is extruded by a rolling mill, so that the thickness of the steel plate is uniform, and set aside;

[0018] 2) Punching processing of the steel plate: the steel plate with uniform thickness obtained in step 1) is sent into the punching machine tool, and the steel plate is punched out by the punching machine tool to obtain a circular steel plate for making a ste...

Abstract

The invention discloses a molding technology for a steel cylinder used for the chemical industry. A steel plate material is subjected to tempering treatment and pressing machining; the steel plate is blanked to be manufactured into a round steel plate; the round steel plate is punched to be manufactured into a steel cylinder blank; the steel cylinder blank is subjected to necking down molding; finally other parts of the steel cylinder are welded to the steel cylinder blank; and the qualified finished steel cylinder is obtained through detection. The molding technology for the steel cylinder used for the chemical industry is scientific, low in cost, safe and reliable, the steel cylinder forming steps can be reduced, and therefore the production time is shortened, and the production efficiency and the product qualification rate are effectively improved.

Description

technical field [0001] The invention relates to a forming process of a chemical steel cylinder. Background technique [0002] As the most widely used special equipment in my country, steel cylinders are widely used in automobile, fire protection, chemical, medical, petroleum, energy, urban construction, food, metallurgy, machinery and other departments as a storage and transportation equipment category. [0003] In the forming process of the existing steel cylinder, the parts of the steel cylinder need to be quenched and tempered many times during processing, especially in the forming process of the steel cylinder, the steel plate used for forming needs to be tempered before stamping, which makes the steel plate easier to process Deformation to obtain a steel cylinder blank, and when the steel cylinder blank is shrinking, the steel cylinder blank must be heated again to facilitate its necking process, but the process of forming the steel cylinder produced in this way has man...
