压缩弹簧，弹簧钢材质，线径 0.3-2mm，外径 3-40mm，弹簧钢 描述

  1. 性能
    • High-Carbon Spring Steel Construction – Coiled from DIN EN 10270-1 grade SH or ASTM A228 (music wire) with tensile strengths between 1 600–2 000 MPa depending on wire diameter (Ø0.3–2 mm). The steel is oil-tempered and stress-relieved at 250 °C, yielding long-cycle elasticity and minimal permanent set.
    • Broad Dimensional Range – Standardised outer diameters Ø3–40 mm and free lengths up to 200 mm cover light tactile push-buttons through to heavy machine linkages. Spring rates span 0.05–35 N mm⁻¹, enabling precise load matching.
    • Shot-Peened & Polished Surface – Compressive residual stresses from shot peening boost fatigue life by 30–50 %. Fine-polish finish (Ra ≤ 0.8 µm) reduces friction in tight guide bores and mitigates corrosion initiation points.
    • Operating Window – Reliable force delivery from −40 °C to +120 °C; modulus varies <3 % across this range, ensuring consistent performance in outdoor, automotive, and electronics environments.
  2. 应用场景与组装要求
    • Precision Mechanisms – Keyboards, microswitches, camera shutters, and medical dispensers employ the Ø0.3–0.6 mm series for crisp tactile response and controlled return forces.
    • Industrial & Automotive – Ø1.0–2.0 mm models act as valve train followers, latch actuators, and vibration isolators where high cycle counts (>10⁶) and compact envelopes are mandatory.
    • Assembly Guidelines –
    – Housing clearance: inner guide diameter = spring OD + 0.15 × wire Ø to prevent side-load buckling.
    – Maximum deflection: limit working stroke to 80 % of solid height to preserve ≥95 % load after 100 000 cycles.
    – End treatment: ground and closed ends offer <3° squareness for even load distribution; unground ends suit low-precision pockets.
    • Pre-Set Option – Factory scragging eliminates early relaxation, allowing designers to use published load values without additional settling allowances.
  3. 操作简便
    • Color-Coded Identification – Each spring is epoxy-tipped in industry-standard colors corresponding to rate and wire diameter, simplifying on-site selection and reducing assembly errors.
    • Ready-to-Install Packaging – Springs are supplied lightly oiled in anti-static trays; quantities ≤500 pcs arrive on continuous strips for automated pick-and-place feeders, while larger diameters are banded in nested stacks to avoid tangling.
    • Tool-Free Fitment – Smaller sizes compress easily by finger pressure; larger units require only a simple compression sleeve or bench vise—no special mandrels or jigs.
    • Dimensional Trace Codes – Laser-etched batch numbers on the last coil link to online datasheets for real-time load/deflection curves and CAD models, streamlining maintenance documentation.
  4. 质量与耐用性
    • ISO 9001 & IATF 16949 Certified Manufacturing – Statistical process control on coil pitch, heat treatment, and surface integrity ensures force tolerance within ±7 % and free-length tolerance within ±1 mm.
    • Fatigue & Load-Relaxation Validation – Sample springs endure 1 000 000 compression cycles at 60 % solid height with force loss <5 %, and exhibit <2 % relaxation after 48 h at 100 °C.
    • Corrosion Protection & Compliance – Optional zinc-phosphate or black oxide coatings provide >72 h neutral salt-spray resistance without affecting spring rate. All materials are RoHS and REACH conformant, free from Cr⁶⁺ and other restricted substances.
    • Comprehensive Documentation – Each shipment includes a 3.1 material certificate and test report covering tensile strength, surface roughness, dimensional checks, and residual stress measurements, assuring predictable, long-term service in safety-critical assemblies.
