Description

Water tower molding method, molding machine and water tower structure made by the molding method

The present invention relates to a water tower forming method, a forming machine and a water tower structure produced by the forming method; in particular, it refers to a method of using the hollow body of the water tower to straddle the position of the upper arm and the lower machine platform of the forming machine to form a manhole Structure (or ring reinforcement rib and/or other processing operations) technology.

The water tower structure used to store water or similar liquids to provide people's livelihood and/or industrial systems is a known art. For example, Taiwan No. 93121076 "Manufacturing Method of Water Tower" discloses a typical embodiment in which metal plates are pressed through stamping dies to press reinforcing ribs, rolled into a cylindrical body, and the upper and lower covers are welded at both ends of the cylindrical body . And, Taiwan No. 93212347 "Stainless Steel Water Tower" and No. 104216772 "Water Storage Tower Structure" patent cases, etc., also provide typical embodiments.

As those familiar with the technology know, this skill is a mature field in the technological development space of the industry. This is because the previous cases disclosed included the improvement or design of the structure of each part of the water tower; for example, Taiwan No. 103205601 "Water Tower Inlet Pipe", No. 102211383 "Water Tower End Cover Combination Structure", No. 89203750, "Water Tower Barrel body reinforcing structure " patent case etc., system has provided concrete embodiment.

A subject related to the application and manufacture of water towers or horizontal water tower structures is that all water towers include a manhole structure at the upper end, which provides personnel inspection, installation of other components, and cleaning of the inside of the water tower...etc.

In practice, the old method is to pass a cylindrical plate made of stainless steel or similar materials and place it on the lower platform of the forming machine or forming device, and match the mold set of the forming machine on one of the cylindrical plates. Draw the position to press out the opening (or manhole area) of a hole structure or the structure type of the annular reinforcing rib, and implement the drawing operation to pull out the eaves of the mouth, and complete the manhole (mouth) structure of the water tower; for example , Taiwan's No. 108115616 "water tower forming method and the water tower structure made by applying the water tower forming method" patent case provides a feasible embodiment.

However, as those skilled in the art know, the size and/or height of the entire molding machine must be increased in response to the increase in the size of the water tower. For example, the water tower body with a diameter of 5 meters should pass through and be placed on the lower machine platform of the molding machine. Meters or more, to avoid the contour of the water tower body from being pushed and deformed when it touches the (horizontal) ground, which will affect the manufacture of the manhole structure (or annular reinforcing rib, other processing operations) or cause variation in its size/contour.

It can be understood that if the body of a water tower with a diameter of 10 meters is to be produced, the height of the loading surface of the lower machine platform of the molding machine from the ground must be kept at least 10 meters above the ground; thus, it can be known that the molding machine should adapt to the size and specifications of the water tower increase, the size and/or height of the entire forming machine must be relatively increased, forcing the forming machine to form a bulky mechanical device, which not only needs to occupy a large space, but also causes the personnel to operate the water tower to straddle the bulky mechanical equipment. Difficulties, troubles and processing, safety issues on equipment; and this situation is not what we expected.

Typically, these references show design skills related to the construction and application of conventional water tower or horizontal water tower systems; they also reflect some of the problems that exist in the actual manufacture of these water tower systems. If the structure and manufacturing operations of the water tower or horizontal water tower system are redesigned to make its technology different from the known technology, its use and operation pattern will be changed, and Different from the old method; or to further improve the manufacturing and forming equipment of the water tower. Due to the increase in the size and specification of the water tower, the size and/or height of the entire forming machine must be relatively increased, so that the forming machine forms a bulky mechanical device and needs to occupy a large area. Issues such as the space of the venue are particularly considered issues. In essence, it will also improve the difficulties, troubles, processing, and safety issues of personnel operating the water tower body straddling the bulky mechanical equipment, and establish a relatively ideal operating mechanism and structural effect.

None of these subjects are taught or specifically disclosed in the above-mentioned reference materials.

Yes, the main purpose of the present invention is to provide a water tower forming method, a forming machine and a water tower structure made by the forming method, to improve the manufacture of the water tower and the forming device due to the increase in the size of the water tower, the size of the entire forming machine and/or The height must be relatively increased, so that the forming machine forms a bulky mechanical equipment, which needs to occupy a large space, resulting in difficulties, troubles, processing, and safety issues for personnel to operate the water tower body straddling the bulky mechanical equipment. . include:
