[0002] In recent years, the international market has taken the volume-to-weight ratio of steel cylinders, that is, the ratio of steel cylinder volume to cylinder body weight, as an indicator to measure the quality of steel cylinders. Products with a large volume-to-weight ratio cannot be recognized by the market. In order to adapt to this international market As a result, new industry standards have been formulated in China. For steel cylinders that do not meet the volume-to-weight ratio index, the bottle wall needs to be thinned. The traditional process uses the thinned bottle body and bottleneck welding method, but this process is complicated and labor costs Too high, low working efficiency, unstable and not firm structure at the welding point, and powerful spinning machinery is used to achieve thinning of the bottle body, but the wear rate of the bottle body material remains high and the cost is high

Embodiment Construction
[0027] refer to Figure 1-Figure 12 The present invention will be further described.
[0028] Such as figure 1 Shown: a stretch spinning bottle body 1, comprising a bottle body 11 and a bottleneck 12, the thickness of the bottleneck 12 is greater than the thickness of the bottle body 11, the bottle body 11 and the bottleneck 12 are integrally formed, the thickness of the bottle body 11 is reduced by The thinning process reduces the thickness, and compared with the traditional process of welding the bottle body 11 and the bottleneck 12, the structure is more stable and strong; at the same time, compared with the traditional grinding process of the bottle body 11, the work efficiency is higher and the cost is lower.
[0029] Such as figure 2 , Figure 5 and Figure 7 Shown: a tool suitable for processing the above-mentioned bottle body, including a base 2, and the base 2 is sequentially provided with an installation rotating device for installing the bottle body 1, and a sp...

Abstract
The invention relates to the technical field of fire extinguisher steel bottles, in particular to a stretch spinning bottle body and a processing tool thereof. The bottle body comprises a base. An installation rotating device for installing the bottle body, a spinning device for thinning and extending the bottle body and a positioning device for positioning the bottle body are sequentially arranged on the base. The base is sequentially provided with the installation rotating device for installing the bottle body, the spinning device for thinning and extending the bottle body and the positioning device for positioning the bottle body. The bottle body is simple in structure and strong in practicality.
