Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a heat insulating sash.

Recently, in order to improve the heat retention and insulation performance of sash used in cold and high temperature regions, Arun shapes are not continuous between the outdoor and indoor areas, but are interposed with a synthetic resin insulation material such as special polyurethane between the aluminum and aluminum. Uses a heat-insulating composite material that is integrally bonded with synthetic resin. To join the synthetic resin and aluminum profile, grooves are formed to ensure overall dimensional accuracy and to allow the synthetic resin to be easily injected into the parts of the aluminum profile where the synthetic resin is to be interposed, and the grooves are formed so as to face the outside. Manufacture an aluminum heat-insulating composite profile that is integrally bonded to the side and the side facing the interior of the room. A synthetic resin such as special urethane is injected into the above-mentioned connecting member groove, and then the connecting member in contact with the heat insulating material portion is cut and removed by machining. Here's an example.

FIG. 73 shows a composite stile for a heat insulating sash in which an outer stile 1 and an inner stile are connected with a heat insulating material 3. The manufacturing method of this frame is “7th
As shown in Figure 17, make an extruded aluminum profile with a flat outer surface for the external frame/inner frame using the connecting material section, and place it horizontally on the extruded aluminum profile as shown in Figure 1. A synthetic resin heat insulating material 3 is injected through the opening part 1 to produce something as shown in FIG. 75. Next, as shown in Fig. 16, the side cutter 3 fixed to the arbor L is cut in the direction of the arrow A in the figure until only the connecting member part DA can be cut off, and the side cutter 3 is fed in the longitudinal direction of the sash bar to cut it. Alternatively, as shown in FIG. 77, the end mill cutter is cut in the direction of the arrow opening until only the connecting member section is cut off, and the sash bar is cut by feeding in the longitudinal direction.

Due to this type of processing, the opening portion 41+ is present from the beginning, and on the other hand, since the connecting member part DA is a combined integrally extruded shape, when the special polyurethane heat insulating material 3 is injected into it, thermal deformation occurs, and the heat insulating material 3 The insulation material 3 when injected is 3 when melted! ~I
Since the Io°C1 reaction assimilation temperature is 60~t o 'C, the temperature during injection manufacturing is high.The above-mentioned monolithic extruded aluminum shape becomes fixed in the thermally deformed state and is eventually fixed, so these are difficult to manufacture. It is necessary to take into account deformation in manufacturing, and final finishing accuracy becomes a problem especially when the shape is complex. There are also ridges/Io 1 on both sides of the opening 11, and grooves 5. If -6 is deep, air may not escape quickly in the melted special polyurethane, and it may not be filled sufficiently.

Furthermore, when injecting insulation, the extruded section must be moved or the insulation injection equipment must be moved, which requires an extremely long floor area and is unsafe due to the movement of the high temperature molten insulation. Measures must also be taken into particular consideration.

The first object of the present invention is to eliminate the problems of the conventional method for manufacturing heat insulating shapes and to obtain highly accurate heat insulating shapes, and furthermore, the present invention aims to eliminate the problems of the conventional method for manufacturing heat insulating shapes, and furthermore, the present invention aims to solve the problems of the conventional method of manufacturing heat insulating shapes, and furthermore, the present invention aims to solve the problems of the conventional heat insulating shape manufacturing method. The first objective is to obtain a method for manufacturing shaped materials.

In the present invention, an extruded aluminum profile serving as an indoor element and an extruded aluminum profile serving as an outdoor IS cable are integrally formed, but the part provided with the heat insulating material is formed into a cylindrical shape, and the end of the cylindrical part is covered with a lid. An extruded aluminum profile is placed upright or obliquely, and a heat insulating material is melted and solidified into the cylindrical body from the top, and the widening part of the cylindrical body is separated with the heat insulating material in between. It was cut along an extruded aluminum profile from two directions.

Next, an embodiment of the method for manufacturing a heat insulating profile according to the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of the insulation profile or product to be obtained. The entire frame is made of shoji frames, and the exterior frame is an outdoor element and the interior! ! A heat insulating material 3 made of synthetic resin such as special polyurethane is provided between the inner frames λ. In the embodiment, special polyurethane is used, but other synthetic resins that are melted and solidified in preparation for the heat insulating material may be used, and the material is not limited thereto.

Projections 3 are integrally formed on the outer stile 11 and the inner stile so as to form tapping holes. The figure shows a stile material that is normally installed horizontally, whereas a stile material that is vertically oriented does not require a tapping hole and does not have a protrusion j. Even without the ridges J, the special polyurethane heat insulating material J has sufficient adhesion strength to aluminum. = There is a gap @t, v between the opposing protrusions 6, 6' and 7, 71 of the outer stile l and the inner stile.

A method of manufacturing a heat insulating profile as shown in FIG. 1 according to the present invention will be described. As shown in Figure 3, the extruded section has a gap t in Figure 1.
, q shows the cross section by changing the diagonal direction of the connecting material i@S/A.

17 connects the outer frame l and the inner frame l to be integrally molded. This extruded profile is designated by the symbol it.

Therefore, in the extruded profile /1, a cylindrical body part /D whose inner diameter has the shape of the heat insulating material J of the product is formed by the connecting parts b and tt, the subsequent outer stile parts, and the inner stile parts. be done. still,
Between the connecting member part 16 and the protrusion 6.41 and the connecting member part/? It is convenient to provide small grooves S between the ridges 71 and 71, respectively.

Next, the extruded profile /I is cut to a certain length and one end is sealed with a lid (FIG. V).

The extruded section it can be stood vertically with the lid O facing down, or it can be supported at an angle. Melted special polyurethane insulation material 3
is injected into the cylindrical body part /9 through the opening of the cylindrical body part /f at the upper end of the extruded profile /l.

The special polyurethane heat insulating material 3 flows down into the cylindrical body part 9 and is filled upward from the lower lid 0. Therefore, the cylindrical body part/? Even if the shape is complicated, as long as the inner periphery is connected in a single stroke, the molten heat insulating material J will remain in the cylindrical body part 19.
Fill it without limit.

Next, when the heat insulating material J solidifies, its cross section becomes as shown in FIG.

Since the heat insulating material 3 is injected into such a cylindrical body part/de, thermal deformation is small. This also means that the shape accuracy can be further improved by making the cylindrical body part/de as symmetrical as possible.

As shown in FIG. 6, the side cutter 3 having the width of the connecting member part 6 is clamped by the arbor collar inserted into the arbor collar, and is inserted into the arbor collar through a key not shown, and the side cutter 3 has a width equal to that of the connecting member part 6. Make a cut until the cutting edge of the cutter 3 reaches the heat insulating material J so that a gap g is created in the direction of
The extruded section 16 is fed in the longitudinal direction, and the connecting section 16 is cut and removed to create a gap t, so that only one side of the connecting section of the external stile and internal stile is separated.

Next, as shown in Figure @7, the connecting member portion 17 is processed. This processing is similar to that shown in Fig. 6, but the width of the side cutter 3 is the width of the gap D, and the diameter of the side cutter λ3 is such that the arbor hole 3 does not touch the locking protrusions 1 and 1. choose something. It is appropriate for these cutting operations to be carried out with the extruded section/l injected with a heat insulating material placed horizontally.

In Figure 1, the connecting material part 14 or /7 is cut together using an end mill router, and a cut is made in the direction of the arrow C in the figure until it reaches the heat insulating material 3, and then the extruded shape material is fed in the longitudinal direction. In manufacturing the heat insulating profile shown in FIG. 1, first, as shown in FIG. /'/ is border/da and l ke 1, i

Next, the injection of the heat insulating material 3 is shown in Fig. It will look like the figure. As shown in Figure 1/, this is inserted into the arbor bracket L via a key not shown, and cut into the cutter jaw J held by the arbor bracket λ in the direction of the arrow shown in the figure.
scrape off. In this case as well, an end mill may be used as the tool. In the embodiment shown in FIG. 11, when cutting the connecting member portion 16, the cutting force is small because groove cutting is not performed. Similarly, 4
As shown in Figure 1, the connecting member part 7 is cut and removed to complete the process.

As described above, in the method for manufacturing a heat insulating shape of the present invention, the external material of the outdoor element and the internal material of the indoor element are connected at the connecting material part to form the heat insulating material injection part of the cylindrical body, and the heat insulating material is injected. Therefore, the shape of the integral aluminum extrusion does not change due to the heat of the insulation material. The cross-sectional shape of the insulation material is 41#! Even if it is, it will be filled sufficiently. Since the extruded aluminum profile is stood diagonally or upright and the molten heat insulating material is injected, the heat melting and injecting device for the heat insulating material is in a fixed position, the device is simple, and the installation space is small.
