Product Advantage

The pneumatic punching press is a versatile and efficient machine used in the brass valve manufacturing process, primarily for precision cutting, forming, and assembling small to medium-sized components. Its reliance on compressed air as a power source makes it suitable for high-speed, clean, and cost-effective production. Below are the key functions of pneumatic punching presses in brass valve production:

1. Precision Blanking and Piercing

Brass valves require numerous small holes, slots, and precise cutouts for fluid control, assembly, and fastening. The pneumatic punching press performs:

• Hole Punching: Drilling precise holes for screws, bolts, and valve seat alignment.

• Contour Cutting: Trimming excess material from valve bodies, flanges, or connecting ends.

• Slot Cutting: Creating grooves for O-rings, seals, or locking mechanisms.

Advantages:
✔ High-speed operation (100–300 strokes/minute) for mass production.
✔ Minimal burr formation due to clean shearing action.
✔ Adjustable stroke and pressure for different brass thicknesses.

2. Forming and Bending Operations

Brass valve components often require small bends, flanges, or embossing for functionality. The pneumatic press can:

• Flange Forming: Shaping the edges of valve bodies for pipe connections.

• Bending Tabs: Creating locking tabs or mounting brackets.

• Coining/Embossing: Adding identification marks, logos, or part numbers.

Advantages:
✔ Consistent force application ensures uniform bends.
✔ Quick die changes for multi-stage forming processes.

3. Riveting and Assembly Pressing

Many brass valves use press-fit components (e.g., stems, seals, bushings). The pneumatic press assists in:

• Bearing & Bushing Insertion: Pressing brass or composite bushings into valve bodies.

• Staking/Riveting: Securing moving parts like valve stems or levers.

• Seat & Seal Installation: Precisely placing elastomer seals or metal seats.

Advantages:
✔ Controlled force prevents brass deformation.
✔ Repeatable accuracy (±0.02mm) ensures leak-proof assemblies.

4. Automated Production Integration

Modern brass valve factories use automated pneumatic presses with:

• Robotic Feeders: Automatically loading brass sheets or pre-cut blanks.

• Ejection Systems: Removing finished parts for conveyor-based sorting.

• Vision Systems: Inspecting dimensions and defects in real-time.

Advantages:
✔ Reduces labor costs and human error.
✔ Enlights Industry 4.0 compatibility with IoT monitoring.
