Transfer Presses
Stamtec presses can customized by a wider range of SPM, stroke, rating point (BDC), bed and other specifications and dimensions.
Custom specifications on request per customer's requirements.
The transfer press was designed to run dies with very large dimensions both l-r and front to back. It can run progressive or transfer dies, running large, odd-shaped or deep-formed parts that require a transfer system to move the parts through the die. Stamtec will work with the transfer system provider of your choice (e.g. HMS, Wayne Trail, Linear, Gudel, Atlas), to completely integrate the transfer system with the press, feedline and other peripheral equipment as necessary.
The drive train is a low inertia, high torque eccentric geared drive system design featuring precision cut, steel-rim eccentric gears, plunger guiding, and double helical gearing for the drive shaft and intermediate gears, all lubricated by an enclosed oil bath and spray system.
S4 Series presses feature eccentric gear drive with plunger guides on each connection to control side thrust and deliver precision slide tracking throughout the stroke. All gear surfaces have been heat treated and finely ground to assure smooth operation and low noise levels.
Press Advantages - Transfer Presses
All gears are produced at CF Stamtec’s state-of-the-art manufacturing facilities, using the most modern gear manufacturing equipment and strict quality control procedures. All large gears are balanced for smooth operation. The result is a press drive system that provides close running tolerances, prolonged life, and smooth, quiet operation.
This type of drive carries much higher torque loads than crankshaft style drives. In addition, no torsional force is transmitted to the main eccentric gear shafts, which helps to ensure precise slide movement. The stamping loads are transferred through the gear teeth and the connection straps, so pressure and wear on the bronze alloy bushings is reduced to a minimum.
The transfer press can run extremely large parts, or large dies with many stations, which can eliminate many secondary operations normally performed outside the press. When used as a transfer press, scrap savings of up to 17% may be achieved because a scrap skeleton is not necessary to move the parts through the die. Stamtec will work with the transfer system provider of your choice (e.g. HMS, Wayne Trail, Linear, Gudel, Atlas), to completely integrate the transfer system with the press, feedline and other peripheral equipment as necessary.
