Description

Water tower forming method and water tower structure manufactured by applying same

Technical Field

The invention relates to the field of battery formation clamps, in particular to a water tower forming method and a water tower structure manufactured by applying the water tower forming method.

Background

Water tower structures for storing water or the like for use in residential and/or industrial systems are known in the art. For example, taiwan patent nos. 93121076 entitled "method for manufacturing water tower", 93212347 entitled "stainless steel water tower" and 104216772 entitled "water tower structure" provide typical examples, which are as follows:

as is known to those skilled in the art, this art is well within the skill of the art in the field of technological development in the industry. This is because the prior art includes the improvement or design of the structure of each part of the water tower; for example, taiwan patent nos. 103205601 entitled "water tower inlet tube", 102211383 entitled "water tower end cover assembly structure", 89203750 entitled "water tower barrel body reinforcing structure" provide specific examples. The application and manufacture of water tower or horizontal water tower structure is that the water tower includes manhole structure in the upper position for the staff to inspect and install other parts and to clean the inside … of the water tower. In practice, the old method is to press a hole structure (or called manhole area) on the planned position of a plate made of stainless steel or similar material, and manually weld a manhole opening of an annular convex body structure on the manhole area to complete the manhole (mouth) structure of the water tower. It is understood that the conventional operation of manually manufacturing (or welding) the manhole opening structure is troublesome, time-consuming, and not conducive to mass production (cost reduction); and after finishing the operation of the manhole opening part structure, bending the stainless steel plate body by matching with a machine tool, overlapping the two side areas of the stainless steel plate body, and performing welding operation to connect the two side areas to form a ring-shaped water tower shape.

It should be noted that such a conventional manufacturing mode often causes the welding area formed by the welding operation to be located at the lower position of the water tower, and after the water tower is loaded with water or the like, the welding area is normally eroded by the water or the like, which causes the content of the water tower to be deteriorated, and such a situation is not desirable.

Representatively, these references show the design skill of the conventional water tower or horizontal water tower system in terms of structure and application; they also reflect some of the problems that these water tower systems have in the case of actual manufacturing. If the combined structure of the water tower or the horizontal water tower system is considered again, the structure is different from the conventional structure, the use form can be changed, and the method is different from the old method; or further the welding zone of the water tower will not contact with water or the like liquid, thereby reducing the deterioration of the water tower content. Substantially, the trouble and time-consuming of manual manufacturing in the prior art are also improved, and a more desirable structural effect and an operation mechanism that facilitates mass production (cost reduction) are established.

These objects are not specifically taught or disclosed in the above references.

Typically, the water tower forming method and the water tower structure formed by the water tower forming method include the following advantages and considerations compared with the prior art:
