Frequently Asked Questions
What is a 6-Mold 6-Punch Cold Heading Machine used for?
This machine is designed for high-speed precision manufacturing of complex fasteners, bolts, and specialized metal parts through a multi-station cold forging process, allowing for intricate shapes and high production efficiency.
What is the maximum production speed of these machines?
The production speed varies by model. For instance, the KD-616 can reach a maximum speed of 95 pieces per minute, while the larger KD-625 operates at 60 pieces per minute to handle heavier forging requirements.
What is the maximum diameter and length this series can handle?
The series covers a wide range of specifications. The KD-625 model can handle a maximum cut-off diameter of 38mm and a maximum cut-off length of 295mm, making it suitable for large-scale fastener production.
How does the 6-station forging process benefit production?
Multiple stations allow for sequential forming steps (such as upsetting, extrusion, and trimming) in a single cycle. This reduces material waste, improves dimensional accuracy, and enables the creation of more complex geometries compared to machines with fewer stations.
What are the power requirements for the KD series?
Main engine motor power ranges from 55KW for the KD-613L up to 132KW for the KD-625, ensuring sufficient forging force (up to 600,000 Kgf) for high-strength material processing.
Is the machine compatible with different bolt sizes?
Yes, each model is designed for a specific range. For example, the KD-620 is applicable for bolt diameters ranging from 12mm to 24mm, providing flexibility for various manufacturing needs.
