# Industrial Specification: Hydraulic Punch Unit

## 1. Technical Definition
A hydraulic-powered punching component within busbar processing equipment that creates precise holes in conductive metal bars.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-300 bar hydraulic pressure, 0.1-0.5 mm positioning accuracy, 20-60°C operating temperature**. Failure boundary: **Hydraulic pressure exceeding 350 bar causes seal extrusion failure, positioning error &gt;1.0 mm causes misalignment, temperature &gt;80°C degrades hydraulic fluid viscosity below 32 cSt**, Mechanism: **Seal failure occurs via extrusion when pressure exceeds material yield strength (EPDM rubber: 15 MPa), misalignment results from hydraulic cylinder stiction exceeding 0.1 N·m at low velocities, thermal degradation follows Arrhenius equation with activation energy 85 kJ/mol for hydraulic fluid oxidation**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
