 Hot Stamping |
Hot stamping is a special method which includes operations
of heating, forming, cutting and quenching of sheet metal. By hot stamping
method, strong and lightweight parts are manufactured.
We take charge of manufacturing dies which hold the key of
a new method of hot stamping. |
 |
 |
■ Dies for Forming
(1/3 Process) |
First process is forming. The dies are kept hot circulating
high-temperature oil through pipes.
Size：1,860*700*900
Mass：5,350Kg
Material: FCD550 |
■ Dies for Cutting
(2/3 Process) |
 |
 |
Second process is cutting off unecessary parts. The same thermal
function as dies for forming is adopted. Edges of cutters are made by SKD
diffusion bonding.
Size: 1,860*800*900
Mass: 4,900Kg
Material: FC250+SKD |
 |
 |
■ Dies for Quenching
(3/3 Process) |
Final process is quenching. Heated products are cooled rapidly by running water through the pipes, and hardened.
Size：1,700*600*900
Size：2,650Kg
Material：FC250+SKD |
| ■Our New Method of Hot Stamping |
 |
Fig.1 shows the process of conventional hot stamping method.
Step-1：Heating steel sheet
Step-2：Forming and quenching
Step-3：Cutting unnecessary parts by a laser.
The process requires laser cutting because products are hardened by quenching.
Fig.2 shows our new method of multistage mold hot stamping.
Three operations of forming, cutting and quenching can be perfomed by single
press machine.
Compared with the conventional hot stamping method, it takes shorter time for stamping. |
