JH31 SERIES CLOSED TYPE SINGLEPOINT PRESS

JH31 SERIES CLOSED TYPE SINGLEPOINT PRESS

The machine body of the JH31 series narrow-table closed type single-point, manufactured through adopting monolithic box type structure (a part of machine models adopts the four-pull level pre-light structure), has the high rigidity.

The crank shaft in the type eccentric shaft has strong bearing capacity; the wet-type clutch has the long service life; the slide block adopts the four-surface full-guideway, so the guiding precision is high and the precision retentively is good.

The crank shaft in the type eccentric shaft has strong bearing capacity; the wet-type clutch has the long service life; the slide block adopts the four-surface full-guideway, so the guiding precision is high and the precision retentively is good.

The die set height is adjusted mechanically and is displayed by digital. The die calibration is easy and rapid; The JH31-400/630/800 adopts the hydraulic overload protective device. The JH31-200-300 adopts the wedge-shape iron die unlocking device.

The complete machine adopts the control method integrating PLC and pneumatic control methods, and it has three kinds of stroke specifications inducing continuous stoke, single stroke and inching.

It can be provided with the photo-electric protection so as to achieve the security and reliability. It can be provided with the automatic feeding device and uncoiling leveling device to achieve automated production; the complete machine has the compact structure, beautiful appearance and reasonable layout.

The product is suitable for stamping and pressure-sizing technologies of various kinds of metal parts and widely used in these industries such as automobile, motorcycle, hardware for daily use, instrument and meter and gas appliance and so on.
