Presses for Blanking Laminations

Product catalog summary
Overview
The document provides detailed information about the high-speed presses and notching machines designed and manufactured by the Galbiati Group. These machines are primarily used for blanking and notching magnetic laminations to produce rotors and stators for electric motors.

Certified Quality
The precision of the presses is ensured through inspections using a ZEISS MMZ-G 30 60 25 three-dimensional measuring machine. Main components are machined in-house to maintain high quality standards.

EP3 and EP4 Presses
  • EP3 Presses: Designed for high-speed blanking applications, offering capacities from 250 to 650 tons. Features include a hydraulic clutch/brake unit, hydrostatic lubrication of bearings, and dynamic balancing. The press is user-friendly with a comprehensive supervision system.
  • EP4 Presses: An evolution of the EP3, featuring dynamic penetration control and overhead shaft assembly for improved productivity and maintenance efficiency. It maintains full blanking force under any condition and includes a quick lift feature for die inspection.

Technical Specifications
  • EP3 Press: Capacities range from 2500 kN to 5500 kN, with stroke lengths of 30 to 40 mm and slide adjustments of 70 to 100 mm.
  • EP4 Press: Similar capacity range with additional features for enhanced performance and maintenance.

Additional Features
Both EP3 and EP4 presses include features such as hydrostatic lubrication, dynamic balancing, and a hydraulic clutch/brake unit. The flywheel design reduces stress on the crankshaft, and the crankshaft is nitrided for extended life.

Presses for Blanking Laminations-4

EP3 Press for High Speed Blanking Magnetic Laminations Full blanking force under any condition The flywheel is anchored to the side frame by means of a bushing in order to avoid stressing the shaft. Oversized, it allows blanking operations to be performed with the rated machine tonnage at very low speeds, lower than those allowed by other presses of equal force. The stiffness of the press bed also guarantees increased die life, a feature particularly advantageous when using hard metal dies. Die Inspection The quick lift, standard on all EP3 presses, allows the upper half of the die to be opened,...

EP4 Press for High Speed Blanking Lamination The EP4 press for high speed lamination blanking is the natural evolution of the EP3 press. A few significant innovations improve production quality and productivity. In particular, dynamic penetration control and overhead shaft assembly have been introduced. Dynamic Penetration Control During blanking, the penetration of the slide can vary due to the elongation of the connecting rods (resulting from heating of the machine). This is particularly critical when stacking laminations. The EP4 press allows you to adjust the penetration during blanking in...

Other Features: Full Blanking Force Under Any Condition The flywheel is fastened to the side upright by means of a bushing in order to avoid stressing the crankshaft. The oversized flywheel guarantees blanking operations to be performed within the rated press capacity, at very low speeds, lower than those allowed by other presses of equal force. The stiffness of the press bed also guarantees increased die life, a feature particularly advantageous when using hard metal dies.
