Is a heat insulating resin sheet as a raw material, 3 is a roller for applying an adhesive, 4 is an adhesive stocker, and 5 is a drying oven. An adhesive (for example, a rubber-based adhesive) is applied to the surface of the metal substrate 1 from the adhesive stocker 4 by the adhesive applying roller 3 with a constant film thickness. After being dried at a constant temperature, the heat insulating resin sheet 2 is integrally formed by compression with the upper compression roller 6 and the lower compression roller 7, and then cut into a certain dimension to form a steel sheet 8 with a heat insulating material. Next, the heat-insulating steel sheet 8 cut into the predetermined size is inserted into the material stocker 9. The inserted steel sheet 8 with heat insulating material is transferred to N / C turret punch presses 10 and 11 by transfer devices 13 and 14.
To perform cutting or pressing.
The transfer devices 13 and 14 include an electromagnetic attraction unit 1.
5, 16 are provided, and the steel plate 8 with the heat insulating material is provided.
Is moved by electromagnetic adsorption. The heat-insulated steel plate 8 processed by the N / C turret punch presses 10 and 11 is stored in a product stocker 12.

を受けないようにして抜き加工する必要がある。In this configuration, the heat-insulating steel sheet 8 is always carried in and out or punched out with the heat-insulating resin sheet 2 up. Since the magnetic steel sheets 8 with heat insulating material are sucked by the electromagnetic suction parts 15 and 16 of the transfer devices 13 and 14, it is stronger to carry in and out the metal substrate 1 with the surface of the metal substrate 1 facing up. When the surface of the resin sheet 2 faces down, the N / C turret punch presses 10, 11
At the time of punching, deformation of the metal substrate 1 in a wavy state occurs. In other words, when the heat insulating resin sheet 2 is partially compressed, local deformation occurs in the metal substrate 1 on the upper surface. This degree of occurrence is remarkable in the case of the heat insulating resin sheet 2a composed of closed cells having a small degree of compression, and is small in the case of the heat insulating resin sheet 2b composed of open cells having a large degree of compression. In the latter case, since the degree of compression is large, the metal substrate 1 is uniformly compressed and the metal substrate 1 is hardly deformed. Therefore, in order to eliminate the deformation of the metal substrate 1,
It is necessary to always perform the punching process with the surface of the heat insulating resin sheet 2 facing up so as not to be affected by the compressive force.

鋼板８をカットしておくことが重要である。In order to minimize the punching, it is also important to cut the heat-insulated steel sheet 8 to a predetermined size before the punching. In other words, the more post-processing the heat-insulated steel sheet 8 is, the more the troubles such as scratches are likely to occur. Therefore, in order to minimize the occurrence of this trouble, it is important to cut the heat-insulated steel sheet 8 in advance to the external dimensions after processing.

And a two-layer structure of the heat insulating resin sheet 2, static electricity is generated due to friction during transfer or stock after processing, and it is necessary to remove the static electricity. In FIG. 2 , the static eliminator 21 is provided at one end of the product stocker 12 in which the steel plates 8 with heat insulating material are vertically stacked, and the static eliminator 21 is vertically moved by a conductor ( The static electricity removing brush 22 made of a metal brush or the like moves (for example, about the thickness of the heat-insulating structure pressing member), and acts to release the static electricity generated in the heat-insulating steel sheet 8 to the ground 25.
