Pressure container end cover machining and forming method

Abstract

The invention provides a pressure container end cover machining and forming method. Pressure container end cover machining and forming equipment is used in the method and comprises a casting and forming device. The pressure container end cover machining and forming method can solve the following problems existing in the pressure container end cover machining and forming process that a, for a pressure container end cover machining and forming mode, a traditional mode is that a machine tool is adopted for punching, a plate is punched to be in an end cover shape, for some thick end cover punching, the mode cannot be taken, the requirement for the device is high, punching defects exist, and the requirement cannot be met; and b, another mode is a casting and forming mode, according to an existing casting and forming device, an end cover formed in a cavity needs to be taken out manually through a tool, the end cover and the cavity are in solidification connection, the end cover cannot be taken out manually easily, and the formed end cover cannot be automatically taken out through the device.

Description

technical field [0001] The invention relates to the technical field of pressure vessel manufacturing and molding processing, in particular to a method for processing and molding an end cover of a pressure vessel. Background technique [0002] A pressure vessel is a closed container that can withstand pressure. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most used ones are in the chemical industry and the petrochemical industry, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the field of chemical industry and petrochemical industry, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industr...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the process of forming the end cap of a pressure vessel: a. For the processing and forming of the end cap of the pressure vessel, the traditional method is to use machine tool stamping to stamp the plate into the shape of the end cap. For some thicker End cover stamping, this method is not advisable, not only has high requirements on the device itself, but also has stamping defects, which cannot meet the requirements; b. For the processing and forming of the pressure vessel end cover, the other is through casting. The existing casting molding device needs to manually take out the end cap formed in the cavity through tools. There is a solidification connection between the end cap and the cavity, which cannot be easily removed manually, and the device itself does not automatically remove the formed end cap.
