A wrinkle grinding device capable of tightening the inner wall of a gas cylinder

Abstract

The invention relates to a grinding device capable of tightening gas cylinder inner wall wrinkles, and belongs to the technical field of large-volume steel gas cylinder manufacturing equipment. The grinding device comprises a base, a support arranged on the base and a grinding unit connected with the support, a moving rod is arranged between the grinding unit and the support, a positioning telescopic rod is hinged between the middle section of the grinding unit and the middle section of the moving rod, the support is provided with a first pull rope with one end fixedly connected with the moving rod and a second pull rope with one end fixedly connected with the moving rod, a winding device for the first pull rope and a winding device for the second pull rope are arranged on the base correspondingly, a first pulley matched with the first pull rope and a second pulley matched with the second pull rope is arranged on the support and located on the two sides of the moving rod correspondingly, and the moving rod, the positioning telescopic rod, the first pull rope and the second pull rope form an angle adjusting mechanism of the grinding unit. The grinding device is simple in structure,convenient to use and capable of grinding a position where conventional equipment can not grind in the inner wall of a gas cylinder.

Description

technical field [0001] The invention belongs to the technical field of large-volume steel gas cylinder manufacturing equipment, and relates to a grinding device for the inner wall of a gas cylinder, in particular to a grinding device capable of tightening the folds of the inner wall of the gas cylinder. Background technique [0002] Large-volume steel seamless gas cylinders are made of chrome-molybdenum alloy seamless steel pipes through spinning (forged in the early stage). Because of their weldless structure, they are ideal equipment for high-pressure gas storage and transportation. At the same time, they also bring inevitable The problem is that after the gas cylinder tube is heated and closed by spinning (forging in the early stage), wrinkles will be formed on the inner wall of the gas cylinder; and these folds are easy to hide crack defects, which need to be treated, especially for high-purity gases. The surface of the gas cylinder is extremely demanding, and the inner ...

Problems solved by technology

[0004] At present, there is no effective mechanical processing method for the inner wall folds at the shoulder of the bottle. Manual observation and manual grinding are generally used. However, due to the small bottle mouth, grinding is difficult, and there are grinding blind spots (such as figure 1 shown), which greatly affects work efficiency and product quality
