4 points of crank supporting & hydro-dynamic bushing. Apex 30-60, bearings are applied both at supporting & connection. The clearance is smaller and B.D.C. is more accurate. Apex 80-220, bearings and hydro-dynamic bushings can stand with thrust and decrease friction area. It can suppress heat expansion to prevent wear throughout the years. 2-set frame of cast iron to ensure verticality. The guiding holes are cast at bed and machined at same time to ensure verticality.
4 Points of Crank Supporting & Hydro-Dynamic Bushing
Apex 30-60, both bearings are applied at supporting and connection. The clearance is smaller and B.D.C. is more accurate.
Apex 80-220, both bearings and hydro-dynamic bushings are applied to keep clearance smaller. Hydro-dynamic bushings can stand with thrust and decrease friction area. It can suppress heat expansion to prevent wear throughout the years.
2-Set Frame of Cast Iron Ensures Verticality
The Apex 2-set frame is designed from cast iron. The guiding holes are cast at the bed and machined at the same time to ensure verticality.
The frame design of other press makers is 3-set. Assembly after machining cannot ensure verticality.
Eccentric Shaft & Dynamically-Balanced Device
The strength of eccentric shafts is greater than general crankshafts. The advantage is less deflection and more power output. Dynamic balancers reserve weight of upper die to eliminate inertia produced by reciprocation. Hence, vibration can be reduced to an extremely low level.
Separated Clutch & Brake
The clutch and brake on the Apex Series is larger than normal, so braking time and angles are less. Balanced load at two sides can reduce the wear of bearings. If mechanical parts fail at the clutch or brake, the press stops immediately.
Slide Quick Access
The height of slide quick access is 50mm with the Apex 30 – 60 and 70mm with the Apex 80-220. It helps users solve problems related to material sticking, tool jamming, scrap or punch changing. After trouble shooting, the return slide is at original height quickly and the B.D.C. is kept still without readjusting.
In addition to saving time, users can select a shorter stroke without being concerned with any inconveniences related to tool operation and inspection. Further, the use of shorter stroke can improve verticality of reciprocation, prolong tool life and increase production.
Guiding Systems of Slide & Hydro-Static Bushings
Dual plungers isolate slide from angular front-to-back movement of connections and bear up more upward eccentric load during stamping. 4 guide posts are applied to symmetrically absorb thrust during stamping. The posts with hydro-static bushings can stand with higher thrust, decrease friction area, and suppress heat expansion to prevent the wear of bearing throughout years of operation.
