摘要： Disclosed herein is a hot forming method and apparatus that can improve strength of a product via die operation. The hot forming apparatus includes a lower die on which a workpiece is placed, an upper die coupled to the lower die to press the workpiece, a holder disposed between the upper and lower dies to form an inner space of the workpiece, and a cooling unit to cool the workpiece. The hot forming method includes coupling an upper die, a lower die and a holder with a workpiece placed on the lower die, followed by pressing the workpiece to perform a hot forming operation, determining whether or not a preset time has elapsed after pressing the workpiece, and cooling the workpiece by supplying a cooling fluid around the workpiece, if the preset time has elapsed.
摘要翻译：本文公开了一种通过模具操作提高产品强度的热成型方法和装置。热成形装置包括：下模，工件被放置在其上;上模联接到下模以挤压工件;保持件，设置在上模和下模之间以形成工件的内部空间;以及冷却单元冷却工件。热成形方法包括将上模，下模和保持器与放置在下模上的工件连接，然后按压工件进行热成型操作，确定在按压工件之后是否经过了预设时间并且如果预设时间已经过去，则通过在工件周围提供冷却流体来冷却工件。
