Title:
COLD PRESS FORMING DEVICE AND COLD PRESS FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/044764
Kind Code:
A1
Abstract:
This cold press forming device comprises a temperature sensor, a heat medium flow path, a heat medium supply flow path that supplies a heat medium to the heat medium flow path, a heat medium recovery flow path that recovers the heat medium from the heat medium flow path, and a pump that delivers the heat medium to the heat medium supply flow path. Furthermore, this cold press forming device comprises a temperature control unit having a temperature adjustment unit that heats or cools the heat medium on the basis of a detection value from the temperature sensor, the temperature control unit controlling the temperature of a die and/or a punch so as not to deviate from a predetermined range extending from a lower-limit value to an upper-limit value.
