Title: Press device
Inventor: OKI KEISHI
IPC: B30B15/04
Filed: 1985-12-24
Abstract: PURPOSE:To improve the work accuracy by providing the guide block which guides a slider to the lower part of a crown by fitting it to one side of the shell part of a main body. CONSTITUTION:The press main body 4 forms a C type frame structure by the main body shell part 6, head part 8 and crown part 10 and a guide block 26 is arranged at the lower part adjoining to the crown part 10 as well. The press forming is performed by the cooperation with the lower part forming means 12 with the vertical movement of the movable upper part forming means 20 which equips with a die set base 22 and forming tool via the guide block 26 and a slider, when the crown shaft 16 is driven with its rotation via the driving device. In this case, the effect of the C type frame being opened in the forking as well can completely be prevented because of the guide block 26 being fitted to the main body shell part 5. Consequently the slider is correctly guided. In this way, the accuracy in pressing can be improved.
