What materials can be processed by this machine?
This machine is typically used for cold forming steel wires, including various grades of carbon steel and alloy steel suitable for producing small fasteners like M1-M5 bolts. Stainless steel and other non-ferrous metals may also be processed depending on the machine's specifications.
How does the 4 Die 4 Blow system improve production efficiency?
The 4 Die 4 Blow system allows for a multi-stage forming process within a single setup, progressively shaping the bolt to its final form with high precision. This reduces the need for secondary operations and ensures faster cycle times, significantly boosting production efficiency.
Can this machine handle different sizes of bolts within the M1-M5 range without major adjustments?
Yes, the machine can accommodate various sizes within the M1-M5 range. However, changing the size typically requires adjusting or replacing dies and possibly some tooling changes. Quick-change systems can minimize downtime during these transitions.
What kind of maintenance is required for optimal operation?
Regular maintenance includes lubrication of moving parts, checking and adjusting die alignments, cleaning to remove metal chips and debris, and periodic inspection of wear parts. Following the manufacturer’s recommended maintenance schedule helps ensure optimal performance and prolongs machine life.
Is it possible to integrate this machine into an automated production line?
Absolutely, this machine can be integrated into fully automated production lines. With optional feeders, conveyors, and robotic systems, it can achieve automatic feeding, forming, quality inspection, and sorting, enabling unattended operation and increasing overall productivity.
