Forming device and forming method

Abstract

Provided is a forming device that forms a heated metal material, the forming device including: a die that performs quench forming by coming into contact with the metal material; a cooling unit that is provided inside the die to cool the die; and a temperature sensor that detects a temperature of the die, in which the cooling unit adjusts a cooling capacity on the basis of a detection result of the temperature sensor.

What is claimed is: 
     
         1 . A forming device that forms a heated metal material, the forming device comprising:
 a die that performs quench forming by coming into contact with the metal material;   a cooling unit that is provided inside the die to cool the die; and   a temperature sensor that detects a temperature of the die,   wherein the cooling unit adjusts a cooling capacity based on a detection result of the temperature sensor.   
     
     
         2 . The forming device according to  claim 1 ,
 wherein the cooling unit makes a temperature of the die fall within a predetermined range.   
     
     
         3 . The forming device according to  claim 1 ,
 wherein the cooling unit increases a cooling capacity as a number of times of forming of the die increases.   
     
     
         4 . The forming device according to  claim 1 ,
 wherein the cooling unit increases a cooling capacity as a forming time of the die becomes longer.   
     
     
         5 . The forming device according to  claim 1 , further comprising:
 a die holder that supports the die,   wherein the die holder includes a supply portion and a discharge portion.   
     
     
         6 . The forming device according to  claim 5 ,
 wherein the cooling unit includes a circulation mechanism that supplies and circulates a cooling medium, and   the circulation mechanism supplies the cooling medium to the supply portion, recovers the cooling medium discharged from the discharge portion, cools the recovered cooling medium, and supplies the cooling medium to the supply portion.   
     
     
         7 . The forming device according to  claim 1 , further comprising:
 a heating unit that heats the metal material.   
     
     
         8 . The forming device according to  claim 7 ,
 wherein the heating unit includes a lower electrode, an upper electrode, and a power supply that allows electric current to flow to the metal material through the lower electrode and the upper electrode.   
     
     
         9 . The forming device according to  claim 1 , further comprising:
 a fluid supply unit that supplies a fluid into the metal material.   
     
     
         10 . The forming device according to  claim 9 ,
 wherein the fluid supply unit includes a nozzle that supplies the fluid to an inside of the metal material, a drive mechanism that moves the nozzle forward and backward with respect to an opening of the metal material, and a supply source that supplies the fluid into the metal material via the nozzle.   
     
     
         11 . The forming device according to  claim 1 ,
 wherein the die includes a first member including a forming surface for forming the metal material and a second member that supports the first member on a side opposite to the forming surface.   
     
     
         12 . The forming device according to  claim 11 ,
 wherein the first member and the second member include dividing surfaces that come into contact with each other, and   the second member includes a slit and a jacket groove that are open on the dividing surface.   
     
     
         13 . A forming method of forming a heated metal material, the forming method comprising:
 a forming process of performing quench forming by bringing the metal material into contact with a die; and   a cooling process of cooling the die,   wherein the cooling process includes an adjustment process of adjusting a cooling capacity for the die by a temperature sensor that detects a temperature of the die.
