Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and more specifically, to a rolling welding equipment for producing gas storage cylinders. Background Art

[0002] Gas cylinders are equipment specially used to store gas and also play a role in stabilizing system pressure. According to the pressure they can withstand, they can be divided into high-pressure gas cylinders, low-pressure gas cylinders, and normal-pressure gas cylinders. Gas cylinders are often welded together by two end caps and a gas tank side wall during production, which requires corresponding welding equipment to weld the gas tank side wall to the two end caps.

[0003] After searching, the Chinese patent publication number CN218284260U discloses "a gas tank end cover welding machine, including a bracket, a drive motor, a cylinder, a left pressure frame, a right pressure frame and a lifting mechanism, the bracket is provided with a welding device, the body of the drive motor and the cylinder body of the cylinder are respectively fixed at both ends of the bracket, the left pressure frame is fixedly connected to the output shaft of the drive motor, the right pressure frame is connected to the push rod of the cylinder through a bearing, and the push rod of the cylinder is coaxial with the output shaft of the drive motor; the lifting mechanism includes two groups of supporting components symmetrically distributed on both sides of the circumference of the output shaft of the drive motor";

[0004] The above patent drives the "left pressure frame" and the "right pressure frame" to rotate through the "drive motor", so that the "gas tank" and the "welding equipment" can roll relative to each other to achieve rolling welding. However, in this process, the "left pressure frame" and the "right pressure frame" squeeze the "end cover", and the "end cover" and the "gas tank" are not fixedly connected before welding. The two rely entirely on static friction to remain fixed. When the "end cover" and the "gas tank" rotate, the "gas tank" will slide and rub against the "end cover" under the action of centrifugal force. At this time, the positions of the "end cover" and the "gas tank" ports will shift, resulting in the "welding equipment" being unable to completely weld and seal the ports of the "end cover" and the "gas tank".
