Deep drawing technology of deep-drawing-shaped simple pressure vessel

Abstract

The invention provides a deep drawing technology of a deep-drawing-shaped simple pressure vessel. The deep drawing technology of the deep-drawing-shaped simple pressure vessel disclosed by the invention is characterized in that an end socket with a straight edge section, which is shaped by deep drawing, is directly used for docking circumferential welding, the technology breaks through a step of conducting circumferential welding on an upper end socket and a lower end socket and a cylinder body of a general simple pressure vessel, two circumferential welding joints are reduced to one circumferential welding joint, and a probability of welding damage is reduced. Meanwhile, the vessel does not have a cylindrical section which is shaped by a rolling plate and has a longitudinal welding joint,so that safety performance is greatly enhanced, production efficiency is increased, and production cost is reduced. Technological design is optimized with a finite element technology, and technologyparameters are optimized, so that the technology is more precise, generation of defective goods is avoided, a design cycle of a single product is reduced, equipment debugging time is reduced, and quality of deep-drawing shaping is improved.

Description

technical field [0001] The invention relates to the technical field of pressure vessel preparation, in particular to a deep drawing process for a simple pressure vessel formed by deep drawing. Background technique [0002] Simple pressure vessels are usually mass-produced pressure vessels. Both TSG21-2016 "Safety Technical Supervision Regulations for Stationary Pressure Vessels" and NB / T47052-2016 "Simple Pressure Vessels" stipulate that the design methods are divided into calculation methods and test methods. The calculation method is: the wall thickness of the pressure components of the container is designed according to the rules of the corresponding chapters of GB150.3; the test method is: the wall thickness of the main pressure components such as the cylinder body, convex head, and flat cover of the container to ensure the strength requirements is adopted The method of determining the bursting test of the physical sample of the container. At present, the design of sim...
