Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method of manufacturing a shutter slat and a shutter slat manufactured by the method. The surface of the shutter slat is a durable and easy-to-decorate aluminum plate, and the back surface is resistant to damage. It is characterized in that it is made of an iron plate material having high wear properties and filled with a foamable resin for heat insulation therebetween.
[0002]
[Prior art]
Generally, a shutter is used as a door for a garage in a house, a door for a low-rise store, or a door of a building entrance / exit. Recently, many types of shutters are forcibly rolled up using the power of a motor, and are used for shutters. An example of a slat can be seen in FIGS.
[0003]
FIG. 1 shows a conventional general slat 10 having a single-layer structure as a pressed iron plate material or a rolled, extruded or drawn aluminum plate material.
[0004]
FIG. 2 is an improvement of the slat 20 of FIG. 1 as described above. In order to cut and use a drawn aluminum plate, the front surface portion 21 and the back surface portion 22 are doubled. In the meantime, the heat insulating material 23 can be filled and put.
[0005]
However, such conventional slats have the following disadvantages.
[0006]
That is, since the front surface portion 21 and the back surface portion 22 are all made of an expensive aluminum material, there is a disadvantage that the product price increases, and when the back surface portion 22 is wound or unwound on a winding drum driven by a motor. However, there is a problem that the friction is extremely easily worn.
[0007]
Not only will the slats be completed, but the thermal insulation 23 will be built in the space inside the slats. However, the productivity of the products including the thermal insulation will be reduced due to the troublesome work, and the price of the produced products will be reduced. Will increase.
[0008]
[Problems to be solved by the invention]
Accordingly, the present invention provides a new shutter slat in consideration of the above-mentioned conventional problems. The main object of the invention is to manufacture a slat, and its surface member is made of an aluminum plate. It is excellent in durability and decoration, and its back member is made of iron plate material, so that the wear resistance is greatly improved and the life is long-lasting. On the other side, the above surface member and back member are integrated. The purpose is to make it possible to significantly improve productivity by incorporating a foamable resin in advance at the time of molding.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the characteristic manufacturing method of the present invention is an aluminum plate material primary forming process in which an aluminum plate material having an arbitrary width is formed into an arbitrary cross section by a primary roll forming means made of multistage rollers. And an iron plate material primary forming process in which an iron plate material having an arbitrary width is formed into an arbitrary cross section by a secondary roll forming means made of a multi-stage roller; an aluminum plate material and an iron plate material that have undergone the primary forming process described above; Insulating material supply process in which foaming resin material is supplied by the resin injection means 41 while the materials are attached to each other, and the aluminum plate material and the iron plate material that have undergone the above-described heat insulation material injection process are joined by the third roll forming means A secondary molding process for molding; after passing through the secondary molding process described above, a heating means that heats at an arbitrary temperature while being arranged above and below may be passed. A heating process for sufficiently foaming the foamable resin material therein; after the heating process is finished, the cutting means 90 cuts it to an arbitrary length and discharges it. The shutter slats made in this way were bent by attaching the front surface member made of aluminum plate material, the outward bent portion that was bent by attaching the upper end of the back member made of iron plate material, and the lower end of each other. It is characterized in that the foamed resin material is filled with the foamed resin material in the space between the front surface member and the back surface member.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a manufacturing method and a product of the present invention will be described in detail with reference to the accompanying drawings.
[0011]
FIG. 3 is a perspective view of a shutter slat made by the manufacturing method of the present invention, and FIG. 4 is a process diagram for explaining the manufacturing method of the present invention.
[0012]
As shown in FIG. 3, the slat 30 of the present invention includes a front surface member 31 made of an aluminum plate, an outward bent portion 33 formed by sticking the upper ends of a back surface member 32 made of an iron plate, and a lower end thereof. Is formed by an inwardly bent portion 34 that is bent by being attached to each other, and the space 35 between the front surface member 31 and the back surface member 32 is filled with the foamable resin material 40.
[0013]
And the process for manufacturing in this way is performed through the process as shown in FIG.
[0014]
First, an aluminum plate material 31a having an arbitrary width is formed into an arbitrary cross section by a primary roll forming means 50 made of a multi-stage roller R, and an aluminum plate material 32a having an arbitrary width is formed into a multi-stage. The primary forming process of the iron plate material formed into an arbitrary cross section by the secondary roll forming means 60 made by the roller R is performed at the same time.
[0015]
The aluminum plate 31a and the iron plate 32a formed at this time are as shown in FIGS.
[0016]
Next, through the above-described primary forming process, the aluminum plate material 31a and the iron plate material 32a are supplied to each other while being supplied with the foaming resin material 40 by the resin injection means 41, Subsequently, a secondary forming process is performed in which the aluminum plate 31a and the iron plate 32a that have undergone the heat insulating material charging process are combined and formed by the third roll forming means 70.
[0017]
The cross section before and after the secondary forming process are shown in FIGS.
[0018]
Next, after passing through the above-described secondary molding process, heating is performed to sufficiently foam the foamable resin material 40 inside by passing through a heating means 80 that heats at an arbitrary temperature while being arranged above and below. After the heating process is completed through the process, the production process is completed through a finishing process in which the cutting means 90 cuts and discharges to an arbitrary length.
[0019]
On the other hand, the shape of the cross section of the shutter slat 30 of the present invention as described above is not limited to the shape shown in the drawings, but the inwardly bent portion 34, the outwardly bent portion 33, and the foamable resin material. As long as it has a space 35 for filling 40, any form is possible. In order to form into another form in this way, the primary roll forming means 50 and the secondary roll forming are performed from the above-mentioned process. This can be easily done by replacing the means 60 and the third roll forming means 70.
[0020]
In the drawings, 30a is a supply roll for a take-up aluminum plate material, and 30b is a supply roll for a take-up iron plate material.
[0021]
【The invention's effect】
The shutter slat according to the present invention as described in detail above has excellent durability and decorativeness because the surface member is made of an aluminum plate, and at the same time the back member is made of an iron plate. In addition, the wear resistance is greatly improved and the life of the shutter is prolonged.
[0022]
Further, according to the shutter slat manufacturing method of the present invention, the foaming resin is previously injected and incorporated in a state where the volume before foaming is small at the time when the front surface member and the back surface member are integrally molded, In this process, since a separate heating process is performed so that these resins are sufficiently foamed, a large amount can be produced quickly while being easy to manufacture, and thus productivity can be greatly improved as well. There is an advantage that it can be offered at a low price.
