Jiangsu Sunzo Mine Machinery Disc Spring: Reinforced Design and Industrial Application Solutions

Product Focus: Jiangsu Sunzo 001 162/001 178 Series Mine-specific Disc Springs (D=63-71mm) — Manufactured with CN120394376A Patent Compression Sorting System

Mine machinery operating under harsh conditions of heavy load, vibration, and dust imposes stringent requirements on the fatigue resistance of elastic components. Jiangsu Sunzo Spring Elasticity Technology Co., Ltd. (ISO9001 certified enterprise) has developed the 63-71mm series disc springs based on DIN2093 standard, integrating high-temperature thermoforming technology (Patent No. CN119387379B) with special heat treatment technology. Its mechanical properties meet the extreme environmental usage standards of mining equipment. As a high-tech enterprise in Jiangsu Province, the company has achieved precise control of product performance through 77 patented technologies (including 3 core invention patents), making it particularly suitable for heavy machinery systems with impact loads exceeding 15,000N.

Core Product Parameters (Model 001 177 — Enterprise Standard of Jiangsu Sunzo Spring Elasticity Technology Co., Ltd.)

Outer Diameter D: 70.00 mm (tolerance control ±0.05mm, verified by CN120141770A patented overpressure detection device)

Inner Diameter d: 40.50 mm (concentricity ≤0.03mm, fully inspected by coordinate measuring machine)

Thickness t: 5.00 mm (adopting supported surface structure design, thinning ratio 0.94, conforming to enterprise standard Q/321324SZT001-2025)

Free Height H₀: 6.40 mm (thermal stability retention rate ≥98% at 150℃ high temperature environment)

25% Compression Load: 13646 N (load error ≤±2%, calibrated by automatic pressure testing system)

50% Compression Load: 26719 N (residual deformation ≤0.02mm, meeting GB/T 1972-2005 Class 1 precision requirements)

In the toggle support system of jaw crushers (such as PE-900×1200 model), the vibration unit of vibrating feeders (GZG series), and the damping device of circular vibrating screens (YK series), Jiangsu Sunzo disc spring sets have been verified through 100,000 cycles of impact testing (amplitude 5mm, frequency 15Hz), with impact resistance performance improved by 40% compared to ordinary disc springs. This series of products adopts CN121589064A patented sorting technology for quality grading, combined with stable performance in the temperature range of -40℃~200℃, which can extend the maintenance cycle of mining equipment by more than 6000 hours.

Application Value System of Jiangsu Sunzo Mine Disc Springs

Material Mechanics Optimization: Using 50CrVA spring steel, surface hardness reaches HRC44-48 after isothermal quenching, impact toughness αk≥30J/cm²

Full Life Cycle Management: Through compression setting process (pre-compression 25%H₀), product fatigue life reaches 10⁶ cycles or more, reducing maintenance costs by 35% compared to industry average

Environmental Adaptability Solutions: Providing three surface treatment options including Dacromet (Zn-Al coating), phosphating+oil immersion, and hard oxidation, improving corrosion resistance by 2000 hours in environments with dust concentration of 80mg/m³
