Petrochemical engineering steel pressure vessel forming processing equipment and processing technology

Abstract

The invention relates to petrochemical engineering steel pressure vessel forming machining equipment and a processing technology. The petrochemical engineering steel pressure vessel forming machining equipment comprises a base, a fixing device and grinding devices, wherein the lower end of the base is connected with the existing ground, the fixing device is installed at the upper end of the base, and the grinding devices are symmetrically arranged on the left side and the right side of the fixing device. According to the device, through mutual cooperation of a first motor, a threaded rod, a guide rod and rectangular sliding blocks, an L-shaped plate is matched to drive circular-arc blocks to do descending motion, a connecting rod can make the two rectangular sliding blocks distributed left and right descend synchronously, and the two circular-arc blocks descend synchronously and extrude the upper end of the pressure container, so that the function of easily fixing the pressure can be achieved, and the phenomenon that the grinding block and the weld joint deviate due to the fact that a foot stool of a pressure container deviates and shakes is avoided.

Description

technical field [0001] The invention relates to the technical field of pressure vessels, in particular to a petrochemical steel pressure vessel forming and processing equipment and processing technology. Background technique [0002] A pressure vessel refers to a closed device that holds gas or liquid and carries a certain pressure. The pressure vessel has a wide range of uses. It has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. The chemical industry and the petrochemical industry are the most used. The pressure vessels used in the petrochemical industry alone account for about 50% of the total pressure vessels. In the field of chemical and petrochemical industries, 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; there are many kinds of pressure vessel manufacturing processes, ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the grinding process, the tripod of the pressure vessel is prone to shift and shake, causing the grinding block to deviate from the weld, so that the grinding block cannot completely cover the weld, resulting in poor grinding effect;

[0004] 2. The existing equipment can only grind one type of pressure vessel, and cannot adjust the height of the grinding block in time according to the diameter change of the pressure vessel, and the friction between the grinding block and the surface of the pressure vessel during the grinding process The magnitude of the force cannot be changed, and fine grinding cannot be carried out in the later stage of grinding
