Description

Technical Field

[0001] The utility model belongs to the technical field of accumulator processing equipment, and more specifically, relates to an accumulator laser welding machine. Background Art

[0002] An accumulator is an energy storage device in a hydraulic and pneumatic system. It converts the energy in the system into compressed energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compressed energy or potential energy back into hydraulic or pneumatic energy and releases it to replenish the system again. When the instantaneous pressure of the system increases, it can absorb this part of the energy to ensure the normal pressure of the entire system.

[0003] The diaphragm accumulator is one of many accumulator products. The diaphragm accumulator includes an accumulator housing, and a rubber diaphragm is provided inside the accumulator housing. In production, the accumulator housing is formed by welding two hemispherical housings. Currently, the welding operation of the accumulator housing is basically carried out by a vacuum electron beam welder. During the welding process, the accumulator diaphragm needs to be placed in a vacuum chamber first, and it takes time to evacuate the vacuum chamber before welding starts. The welding steps are cumbersome, resulting in a long duration for the welding process of the accumulator housing, which greatly restricts the production efficiency. Summary of the Utility Model
