By performing the process and the adhesion process of bonding the core to the surface material under pressure using the same equipment, installation space is reduced, process continuity is achieved, and the thermal energy required for bush attachment is effectively utilized.

In general, a core panel obtained by bonding to both sides of a core material such as a honeycomb core or a spiral core, which uses a face material shaped into a certain three-dimensional shape as a core material, consists of a forming device that obtains the face material, and a core panel that is obtained by bonding the face material to both sides of the core material. Normally, the core was manufactured by separately equipping an adhesive device for bonding the core and the core together under pressure.

According to this, separate equipment space was required for the molding equipment and pressure bonding equipment, making the process intermittent, and furthermore, it was necessary to reheat the Omenmura that had been heated to a high temperature in the molding equipment to the bonding temperature. . This invention was made in view of the above-mentioned circumstances, and specifically includes a surface material having rising pieces provided at both ends in the middle direction and a recess formed on the back surface, and a core material adhered to the recess of the surface material. A movable block comprising a female mold having a molding recess and a male mold corresponding to the female mold, the male mold corresponding to the recess of the female mold. It consists of a fixed block disposed on both sides of the movable block, and a core panel having a movable range that protrudes from the same plane with respect to the fixed block with a drag force when the movable block receives external pressure. It provides manufacturing equipment.

Hereinafter, the present invention will be explained based on the drawings of the embodiments.

FIGS. 2 to 5 are cross-sectional views showing the operation of forming and adhering the siding board shown in FIG. 1 as a target object in a manufacturing apparatus according to an embodiment of the present invention, and specifically, FIG. FIG. 3 shows the molding stage, and FIGS. 4 and 5 show the pressure bonding stage.

First, the object shown in FIG. 1 will be explained.

This siding board 100 has a rising piece 7a that slopes upward and outward at one end in the middle direction, and a rising piece 7b that faces the rising piece 7a at the end of the pond to form a recess 8 in the hair surface, and the rising piece 7b A flange 9 parallel to the center piece 8a is provided on the surface material 1, and a core material 4 is attached to the recess 2 of the surface material 1. A mechanism 13 into which the flange 9 is inserted by bonding the back material 5 is formed by the rising piece 7b on the opposite side of the flange 9 and the back material 6. Here, as the front surface material 3 and the back surface material 5, wooden veneer, various other synthetic resin boards, etc. are used. The core material 4 may be made of paper or synthetic resin, for example, an assembly of cylindrical cross-sectional bodies known as a honeycomb core. The core material 4 is bonded to the front surface material 3 and the back surface material 5 by adhering the end surface formed by the thickness of the constituent material of the cylindrical body constituting the core material 4 to the front surface material 3 and the back surface material 5. As the adhesive, a urethane resin, a hardwood type resin adhesive such as a urea melamine resin, or an epoxy resin is preferable. This is because thermoplastic resin adhesives do not provide sufficient strength, particularly adhesive rigidity, and tend to lose their shape when exposed to external pressure. Next, an embodiment of the present invention relating to the manufacture of a siding board having the above structure will be described.

In FIGS. 2 and 3, 31 is a female mold, 32 is a male mold corresponding to this female mold 31, and the female mold 31 has a recess 33.
The opposing inner surfaces of this recess 33 are connected to the rising piece 7 of the object.
One side has a slope 14 that slopes upward and outward in accordance with the slope 14, and the other side faces the slope 14 and has an object 7a.
A rising surface 15 corresponding to the above is formed.

On the other hand, the male die 32 consists of a movable block 16 corresponding to the recess 33 of the female die 31 and fixed blocks 17 disposed at both ends of the movable block 16.
6 has a movable range in which it protrudes from the molding surface 20' of the fixed block 17. In other words, the movable block 16 whose movable range is an area protruding flush with the molded surface 20 of the fixed block 17 is supported by a spring 19 on the base 18 fixed to the fixed block 17, and the pressure applied to the spring 19 is zero. At this time, the movable block 16 protrudes from the molding surface 20' of the fixed block 17, and as the applied pressure increases, the movable block 16 moves in the direction of displacing flush with the molding surface of the fixed block 17 while generating a resistance force. It is composed of The molding surface 20 of the fixed block 17 corresponds to a molding surface 22 consisting of the inner surface of the recess 33 of the female mold 31 and a horizontal surface extending outward from the inner surface, and this molding surface 22 prevents the surface material 3 from rising. Piece 7a, 7
b and flange 9 are formed. That is, the material 21 to be molded is introduced between a male mold 32 and a female mold 31 as shown in FIG. 1, and then the male mold 32 and female mold 31 are clamped together as shown in FIG. A surface material 3 is obtained through a molding step. In other words, the molding surface of the female mold 31 and the male mold 3 are flush with this molding surface.
The material 21 is subjected to ball pressure from the forming surface 2 and is bent and formed. At this time, in order to avoid bending with cracking, the male die 32,
A heater is embedded in the female mold 31, and the heat generated by the heater softens the material 21 during the process. In addition, 23 is a rotary blade that cuts the ears at both ends of the material 21 subjected to molding, and the ears extending to the rising piece 7a have the vertical axis as the rotation axis, and the ears extending to the flange 9 have the machine axis as the rotation axis. That is.
Next, the surface material 3 obtained by molding the material 21 is held in a female mold 32 heated to a high temperature as shown in FIG. 4, and is maintained at a high temperature without overflowing. A core material 4 bonded to the recess 2 and a back material 6 bonded in advance to the core material 4 are arranged in correspondence with each other directly below the movable block 16 of the male die 32. After that, the male type 32 is replaced with the female type 3.
1, the movable block 16 presses the back material 5. At this time, adhesive is applied to either the core material or the recess 2 of the surface material 3, and under pressure from the movable block 16, the core material 4 and the surface material 3 held at high temperature undergo a crosslinking reaction. Bonds quickly under accelerated temperatures. The movable block 16 that presses the back material 5 is held at a position where the resistance force generated in the spring 19 supporting the movable block 16 is balanced. That is, since the pressure required for adhesion is lighter than the molding pressure to obtain the surface material 3, the movable block 16 stops when it protrudes from the molding surface of the fixed block 17, and the core material is inserted between the back material 5 and the surface material 3. 4 is pressed with adhesive. As described above, according to the present invention, the surface material 3 is formed by providing the rising pieces 1 at both ends in the middle direction and forming the recesses 2 on the back surface.
When manufacturing a core panel 6 consisting of a core material 4 bonded to the recess 2 of this surface material 3 and a back material 5 bonded to this core material 4, a forming process is performed to obtain the surface material 3 from a flat material. The adhesion process of adhering the core material 4 to the surface material 3 can be performed in the same device, and the thermal energy given in the molding process can be used for the thermal energy required for adhesion, leading to improved productivity. be.
