Product Specifications

Technical details and manufacturing context for Precision Tooling (Die & Punch)

Definition
Precision tooling consisting of matched die and punch sets that work together within a Precision Pressing Station to perform accurate cutting, punching, or forming operations on various materials. The die provides the stationary cutting or forming surface, while the punch is the moving component that applies force to the workpiece against the die. This product is a component used in the fabrication of metal products, specifically in stamping and forming processes. The tooling is manufactured from materials such as tool steel, carbide, and high-speed steel, which are selected for their hardness, wear resistance, and toughness. Key parameters include die height (50–300 mm), punch diameter (1–50 mm), working pressure (1.0–1.6 MPa), tolerance grade (IT5–IT7 per ISO 286), surface roughness (0.2–0.8 µm Ra per ISO 1302), hardness (58–62 HRC per ISO 18265), operating temperature (-20 to 120°C), maximum strokes per minute (60–120 min⁻¹), die material (Cr12MoV per GB/T 1299), punch material (W6Mo5Cr4V2 per GB/T 9943), and weight (5–50 kg). These values are reference ranges and must be verified for the specific model and application. The tooling is designed to fit specific press shut heights and must be selected based on the required operation, material type, and production volume. Proper alignment and maintenance are critical for consistent performance and longevity. Users should consult the legal manufacturer or supplier to confirm exact specifications and compliance with applicable standards.
Working Principle
The punch moves downward with controlled force and precision alignment to press material against the die, which contains the desired shape or cutting edge. This action either cuts through material (blanking/punching) or forms it into specific shapes (forming/bending) through plastic deformation or shearing. The die is stationary and provides the counter-surface, while the punch is the moving component. The process requires precise alignment and force control to achieve accurate dimensions and surface finish. The tooling must be properly installed and maintained to ensure consistent operation and to prevent premature wear or failure.

Frequently Asked Questions

What materials are used for the die and punch?

The die is typically made of high carbon chromium steel (Cr12MoV) per GB/T 1299, and the punch is made of high-speed steel (W6Mo5Cr4V2) per GB/T 9943. Other materials like carbide may be used for specific applications, but these are the reference grades listed.

What is the typical tolerance grade achievable?

The tolerance grade is IT5 to IT7 as per ISO 286. This indicates a high precision level suitable for critical dimensions, but the actual achievable tolerance depends on the specific tooling design and press conditions.

How do I determine the correct die height for my press?

Die height ranges from 50 to 300 mm. It must match the press shut height to ensure proper operation. Always verify the required die height with the press specifications and the tooling manufacturer.

What maintenance is required for these tooling components?

Regular inspection for wear, proper lubrication, and alignment checks are essential. Surface roughness and hardness should be monitored. If operating temperature exceeds 120°C, tool steel may soften, so cooling may be needed. Follow manufacturer guidelines for maintenance intervals.
