Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a composite molding material, which forms one composite molding material by joining two molding materials.

For example, as shapes used for window frames and frames increase in size, manufacturing equipment becomes larger, making production difficult and increasing costs. Further, when a mold material partially colored in a different color is required, it is extremely difficult to mold it all at once.

The present invention provides a method for manufacturing a composite molded material that can easily form one composite molded material by joining two molded materials, thereby solving the above-mentioned conventional problems.

Hereinafter, the joining method of the present invention will be explained in detail with reference to the drawings.

First, as shown in FIGS. 1A and 1B, a first mold material 1 and a second mold material 2 to be joined to each other are each independently extruded from a plastically deformable metal material such as aluminum. Ru. In this case, as is clear from FIG. 1A, the joint surface of the first profile 1 has a dovetail-shaped connection between the fixed projecting wall 3 that does not deform and the fixed projecting wall 3 that is deformed by caulking. Groove 5
Two sets of deformed protruding walls 4 are provided vertically to form a deformable projecting wall,
The deformed protruding walls 4, 4 are formed in a vertically curved state in which the mouth edge 5a of the connecting groove 5 is expanded.
At this time, grooves 6 may be provided at the base of the deformed projecting wall 4 to facilitate caulking, which will be described later.

On the other hand, on the joint surface of the second profile 2, as shown in FIG. Protrudes in the length direction.

Next, as shown in FIG.
Both shapes 1 and 2 with protrusions 7 and 7 fitted inside
is fed between the left and right support rollers 8, 8, which are rotatable around a vertical axis, and these support rollers support the sides of both shapes 1, 2 in contact with each other, so that both shapes 1, 2 are 1 and 2 are advanced at a predetermined speed by an appropriate feeding mechanism, the deformed projecting walls 4 and 2 are moved by caulking rollers 9 and 9 that rotate around horizontal shafts that are brought into contact with the upper and lower surfaces of their joints. 4 to the fixed projecting wall 3, 3 side. As a result, the connecting grooves 5, 5
The protrusions 7, 7 are engaged inside, and the two molded materials 1, 2 are joined together to form one composite molded material. In this case, if the positions of the support rollers 8, 8 and the caulking rollers 9, 9 are placed as close as possible to the direction of movement of the shapes 1, 2, the deformation of the shapes 1, 2 due to the force during caulking can be more effectively prevented. It can be prevented.

Both of the mold members 1 and 2 may be made of metal such as aluminum, but the first mold member 1 having the deformable projecting wall 4 is made of metal, and the second mold member 2, which does not require plastic deformation, is made of synthetic resin. It is also possible to make it.

As described in detail above, according to the present invention, two molded materials brought into contact are supported from both sides by support rollers, and in this state, while both molded materials are advanced, the deformed projecting wall is caulked by the caulking roller. As a result, the two shapes can be joined very stably and quickly, and the support rollers can reliably prevent the shapes from deforming due to the force during caulking. Therefore, it is possible to easily manufacture large-diameter shapes and composite shapes partially having different colors and different materials, which cannot be manufactured using conventional equipment.

Claims (1)

[Claims] 1. A first mold material having a fixed protruding wall and a deformable protruding wall forming a connecting groove on the joint surface, and a second mold material having a connecting protrusion on the joint surface are each independently molded, and the above-mentioned protruding By feeding both shapes with the strips inserted into the connecting grooves between the left and right support rollers, these shapes are supported by the support rollers from both sides, and while moving both shapes forward, the deformation protrusion is caused by the caulking rollers. A method for manufacturing a composite shaped material, characterized in that a protrusion is engaged in the connecting groove by caulking the wall.
