Frame and bed
Frame rigidity, bed envelope, access, and foundation planning are reviewed with the die and production duty.
A rigid-frame pneumatic press platform for repeat punching, blanking, forming, and compatible progressive-die production.

RESUMEN DEL PRODUCTO
JH21 selection begins with the die, force curve, stroke, shut height, feeding method, guarding, and intended production duty. The whole press scope must be reviewed with the real tool and part.
ESTRUCTURA DE MÁQUINA
Frame rigidity, bed envelope, access, and foundation planning are reviewed with the die and production duty.
Slide travel, guide condition, and adjustment range are matched to the shut height, die envelope, and work sequence.
The drive, clutch/brake scope, and control method are selected with stroke pattern, cycle demand, and site operating procedure.
Die dimensions, fastening, material direction, worktable access, and repeat stops determine the useful press configuration.
Manual or matched feeding, discharge, part handling, and inspection flow should be reviewed with the output target.
Guarding, control mode, access, service space, and safety procedure are confirmed before operation.
PUNTOS DE CONFIGURACIÓN
Provide die drawing, blank or strip direction, stages, shut height, required force calculation, and expected work position.
Confirm material grade, thickness, coil or blank format, finished geometry, edge condition, and tolerances.
Define feed method, target output, loading, discharge, inspection, guarding, and operator method.
