Description

Technical Field

[0001] The invention relates to the technical field of pressure-resistant head production, and in particular to a preparation device for a high-strength pressure-resistant head and a use method thereof. Background Art

[0002] In pressure vessels, chemical equipment and other industrial fields that need to withstand high pressure environments, high-strength pressure-resistant heads are key components, and their performance stability and manufacturing quality are directly related to the safety and reliability of the overall equipment. Traditional head preparation methods mainly include cold stamping, hot stamping and spinning processes, each of which has its own unique advantages and limitations.

[0003] The existing high-strength pressure-resistant head cold stamping and hot stamping both rely on high-precision molds for molding. For heads of different shapes and sizes, different molds need to be customized, resulting in high mold costs. In addition, once the mold is made, its scope of application is limited, and it is difficult to flexibly adjust it to meet diverse production needs. During the stamping process, large waste often occurs at the edge of the material, which reduces the overall utilization rate of the material and increases the production cost. This waste is particularly obvious for high-strength materials. Cold stamping has high requirements for material strength. For thicker or higher-strength materials, cracking, deformation and other problems are prone to occur. Although hot stamping can improve these problems to a certain extent, the heating process is prone to changes in material organization, affecting the mechanical properties and corrosion resistance of the head. As two independent metal processing methods, stamping and spinning each have certain defects in terms of mold cost, material utilization, forming quality, safety issues, processing range, surface quality and production efficiency. In practical applications, it is necessary to select a suitable processing method according to specific production needs and processing conditions, resulting in complex processing steps and low production efficiency.

[0004] In view of this, research and improvement are carried out on the existing problems, and a preparation device and a method for using a high-strength pressure-resistant head are provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Summary of the invention
