After the hole-forming operation, a brick can be pasted on the ground side 3a as required (figure omitted).

In summary, the forming device 2 of the present invention mainly forms a plurality of protrusions 220 on the second pressing surface A2 of the second mold 2b, so that a plurality of concave parts 300 are formed on the ground side 3a of the target object 3, And the depth R (1.5-4.5mm) of the recess 300 is deep enough to make the thickness t of the bottom surface 300a of the recess 300 thinner, as shown in Figure 4C, so that the thickness t (0.40-1mm) is smaller than the plate body The thickness D1 of 30 (about 1.5~5mm), so compared with the conventional technology, when the perforation is formed at the recess 300, the thickness t (that is, the spacing distance) at which the perforation is scheduled to be formed on the ground side 3a is extremely thin , so that the depth of the hole is greatly reduced, which is beneficial to processing, and the problem of stress concentration will not be caused on the ground side 3a and/or the honeycomb side 3b, so as to avoid the occurrence of structures on the ground side 3a and/or the honeycomb side 3b The problem of cracking can be solved, thereby improving the production yield and reliability of the raised floor.

Furthermore, by reducing the thickness of a part of the plate body 30 (that is, the recess 300), in the process of forming the hole, the stamping method can be used, so that the punch used for forming the hole produces very little debris, and During the stamping process, the punch will push the debris out of the perforation in a direction away from the perforation, so no debris will remain in the perforation, so there will be no dust to cause environmental pollution.

Also, because the position of the perforation is aligned with the position of the recess 300, the punch used for the hole forming operation can be aligned with the position of the recess 300 before forming the hole to perform the hole forming action, so the punch can be moved from the honeycomb side 3b Pass through towards the ground side 3a to flush out the debris, thereby avoiding the problem of the debris remaining in the perforation, so that the perforation of the raised floor can effectively avoid blockage and quickly complete the perforation operation.
