Mechanical Punching Press, Type J21S

Key Parameters Main motor: Siemens-Germany Electrics: Schneider- France Safety fence: left and right safety fence Safety standards: CE ISO SGS Features: This series power press machine features rigid rotating-key clutch, simple structure, easy operation and convenient maintenance, driven by helical gear. J21S-25 open inclinable punching machines are the domestic first batch of punching machine equipped with ball bearings, high resistance and low noise, instead of traditional sliding bearing (copper tile). J21S open-type inclinable punching machine is unique in the industry, copper tile transmission gear. The improved frame offers high strength and durability. All J21S-80T above punching machines: pneumatic double balancing cylinder structure keeps the slider weight and the upper die weight balanced to prevent shaking. These power press machines can prevent gear colliding, minimize noise, eliminate the gap between connecting rod and slider, and reduce impact and wear of loaded parts. These press machines prevent the slider from falling down when accidents occur such as brake failure or connecting-rod breaking down.
