Description

GRP water tank panel assembly hole processing apparatus {The assemblage hole processing apparatus for GRP water tank panel}

The present invention relates to a GRP water tank panel assembly hole processing device, and more particularly, to a GRP water tank panel assembly hole processing device that automatically drills assembly holes for inserting bolts for assembling a water tank into the outer surface of a GRP panel molded into a plate shape.

As is well known, water tanks are installed outdoors or underground in order to distribute water. The water tank is manufactured separately using iron plate, FRP, stainless steel, and SMC and installed outdoors or underground.

GRP (Glass - Fiber Reinforced Plastics) (Glass Fiber Reinforced Polyester Resin) and ENM (Elvan Nephrite Marlle) are materials that are lightweight and have excellent durability. These GRP and ENM are made into panels (plates) of a certain shape by pressing SMC (Sheet Molding Compound), which is one of the molding techniques for shaping products.

Since the panel manufactured by the above-described SMC (Sheet Molding Compound) compression molding (hereinafter referred to as a GRP panel) not only exhibits excellent mechanical properties, but also has excellent corrosion resistance and formability, it is in the limelight as a new structural and functional material. A water tank constructed by assembling GRP panels (SMC panels) in a rectangular box shape is widely used.

In particular, the prefabricated water tank, which is assembled and completed at the installation site using the GRP panel as described above, is not only easy to install by assembling the GRP panel (unit panel), but also easy to arbitrarily adjust the size of the tank, so its use is increasing.

In particular, the prefabricated water tank, which is assembled and completed at the installation site using the GRP panel as described above, is not only easy to install by assembling the GRP panel, but also easy to arbitrarily adjust the size of the tank, so the use of the prefabricated water tank is increasing.

As a representative technology related to a water tank using the GRP panel (SMC panel), Republic of Korea Intellectual Property Office Publication No. 10-2012-0134841 (Name: Water tank manufacturing method with an aluminum insulating cover) (hereinafter referred to as prior art) can be cited as an example.

The prior art relates to a method for manufacturing an SMC water tank in which an aluminum insulating cover is installed. In the method for manufacturing a water tank by combining a plurality of unit panels, the water tank manufacturing method comprises the steps of manufacturing an SMC unit panel constituting the main body of the water tank, manufacturing an aluminum unit panel constituting the insulating cover of the water tank by press-processing an aluminum plate, manufacturing a water tank body by combining the SMC unit panels with each other, and installing a water tank insulating cover by attaching aluminum unit panels on the water tank body.

On the other hand, in order to manufacture a GRP panel in the prior art, a GRP sheet is put into a molding mold, then foamed and molded into a panel shape, and then the GRP panel of the finished product is molded through a trimming operation to remove burrs remaining on the outer surface of the molded product. Assembly holes are drilled in the outer surface of the molded GRP panel so that each GRP panel can be connected and fixed to each other with a fastening means such as a bolt when assembling a water tank.

However, as the GRP panel is molded in various sizes according to the size of the water tank, it was difficult to implement a punching device for punching holes according to each standard. Therefore, after marking the hole punching location on the outer surface of the GRP panel, workers had to manually punch with equipment such as a drill, resulting in poor workability and productivity.
