Problems solved by technology

However, the processing cost of the tailless vacuum sealing method is relatively high, and if the pressure vessel is dropped during use, the sealed glass is easily broken, thereby destroying the vacuum environment and causing the pressure vessel to lose its insulation effect

Abstract

The invention discloses a vacuum pumping welding device and method for a pressure vessel. The vacuum pumping welding device for the pressure vessel comprises a frame, a placement chamber provided witha placement cavity and arranged on the frame, a pressure vessel clamp arranged in the placement cavity, a vacuum pumping mechanism communicating with the placement cavity, and a laser welding machinearranged on the frame and used for hermetically welding the pressure vessel, wherein the pressure vessel clamp comprises a lower jaw plate arranged in the placement cavity, a first drive motor for driving the lower jaw plate to rotate, and an upper jaw plate rotationally arranged in the placement cavity along its own axis and positioned on the upper side of the lower jaw plate, and a drive component used for driving the upper jaw plate to move close to or far from the lower jaw plate. The vacuum pumping welding device for the pressure vessel is simple in structure, simple in the vacuum pumping welding process of the pressure vessel, low in cost, and good in hermetically welding effect. The vacuum pumping welding method for the pressure vessel is simple in vacuum pumping welding step of the pressure vessel, and good in hermetically welding effect.

Description

technical field [0001] The invention relates to the field of pressure vessel vacuum welding, in particular to a pressure vessel vacuum welding device and a pressure vessel vacuum welding method. Background technique [0002] At present, there are three main methods of vacuum sealing for metal pressure vessels in the market: seal with tail and seal without tail. [0003] Tail seal means that there is a hidden tail chamber at the bottom of the pressure vessel after vacuuming, and there will be a small tail in the chamber. The process is to weld a copper tube on the hole where the pressure vessel draws out the air (the sealing of the welding is very good) Copper tube The size of the tube is the same as the hole diameter. The interlayer air between the inner tube and the outer tube of the pressure vessel is evacuated through the copper tube. After the vacuum is drawn, the copper tube is cut off. The deformation of the copper tube during cutting is used to achieve a sealed state....
