[0050] figure 1 is a front view of the corrugated plate manufacturing apparatus 10 according to the first embodiment of the present disclosure. The corrugated sheet manufacturing apparatus 10 is an extrusion apparatus for manufacturing a corrugated metal sheet product having a corrugated pattern comprising alternating ridges and grooves arranged continuously and alternately one after the other to form the corrugated pattern. Specifically, the corrugated plate manufacturing apparatus 10 is formed by using a metal plate made of an aluminum alloy as the material 92 Figure 17 The inner heat sink (used as a corrugated metal sheet product) 90, which is a corrugated metal sheet product. The corrugated plate manufacturing apparatus 10 forms the inner fins 90 such that alternating ridges and grooves are continuously and alternately arranged one after the other in the first direction DR1 to form a corrugated pattern (see figure 2 ).

Abstract

In a corrugated plate manufacturing apparatus, each of a plurality of primary forming punches includes a plurality of primary pressable portions that are arranged one after another in a slider reciprocating direction and are pressable by a corresponding one of a plurality of primary sliders. When the primary sliders are sequentially moved toward one side in the slider reciprocating direction, each corresponding one of the primary sliders presses the primary pressable portions of the corresponding one of the primary forming punches to press the primary forming punch against a secondary die.

Description

technical field [0001] The present disclosure relates to corrugated sheet manufacturing equipment for forming corrugated sheet metal products. Background technique [0002] There are various known corrugated sheet manufacturing apparatuses which form a corrugated metal sheet product having a corrugated pattern comprising alternating ridges and grooves by an extrusion process. For example, JP2010-264495A discloses one such manufacturing equipment. The manufacturing apparatus of JP2010-264495A includes an upper mold and a lower mold, which are opposed to each other in the up-down direction. The upper die includes a plurality of extrusion punches which are stacked one after the other in a direction perpendicular to the up-down direction. The extrusion punch of the upper mold is lowered to abut on the processing surface of the block member of the lower mold so that the material of the sheet metal product is plastically deformed by a predetermined extrusion force applied from t...
