Manufacturer middle speed press machine JH21 Series hydraulic press machine

JH21 Series C-frame Fixed Bolster Press Machine

Features:

• Double pneumatic cylinder counterbalancing the weight of the slide and upper mold
• can reduce the impact and noise, so as to eliminate the clearance between the connecting rod and slide.
• By means of the PLC and pneumatic controls, this machine can carry out various actions.
• Through the universal selector switch, it can perform the following:
• 1) inching; 2)single stroke; 3)continual punching; 4)emergency stop.
• The key components such as slide, guideway, bloster and connecting rod use high intensity
• castiron with resin sand structure. Comparing with clay sand structure, their surfaces have 1~2 degree
• improved roughness and 2~3 degree improved precision.
• The types over 60Tons are equipped brake motor which can adjust the shut height automatically.
