Product Overview

The KR-219 automated mechanical fatigue tester is specially engineered for cyclic compression aging tests of coil springs, rubber bumpers, silicone elastic parts and all kinds of elastic hardware components. It adopts mature motor-reducer-cam linkage transmission structure, converting rotary motion into stable vertical reciprocating compression stroke to simulate long-term repeated service load of elastic workpieces. Users can customize test frequency and reciprocating travel to match product technical standards, with full-automatic cycle counting and timed shutdown functions to realize unattended long-duration fatigue verification.
This bench fatigue unit is widely adopted by spring manufacturers, auto parts factories, shock absorber R&D workshops and university mechanical labs for elastic component service life assessment, raw material batch screening and finished product reliability inspection.

Core Product Highlights

  1. Stable Cam Linkage Reciprocating Drive System
    Equipped high-torque AC motor matched with precision reduction gearbox, the eccentric cam converts rotation into uniform up-and-down compression movement, delivering consistent loading force without sudden impact. The whole transmission frame is thick steel welded, anti-vibration structure avoids frame shaking during millions of cyclic tests, ensuring long-running stability and reducing mechanical wear.
  2. Freely Adjustable Test Amplitude & Frequency
    Two independent adjustable parameters fully adapt diverse elastic specimens: reciprocating stroke (amplitude) can be manually calibrated within 0–80mm, cyclic frequency ranges from 0 to 5Hz stepless regulation. Operators set stroke and frequency according spring free length and compression travel requirements, covering small precision micro-springs and large industrial buffer elastic parts.
  3. Digital Programmed Counting & Auto Stop Function
    Large LCD Chinese-English dual display control panel supports preset total test cycles (max 99,999,999 times). Once the machine completes the pre-set number of reciprocations, it automatically cuts off drive power and triggers sound reminder, eliminating manual timing supervision during multi-day continuous fatigue experiments. It also supports manual pause and emergency stop at any time.
  4. Wide Specimen Adaptable Test Space
    Standard internal test cavity fits specimens with maximum length 160mm and outer diameter up to φ100mm. Custom lengthened test chamber and widened fixture platform are available for oversized shock-absorbing springs, large-diameter rubber blocks and composite elastic assemblies, meeting diversified product test demands.
  5. Multi-Layer Built-In Safety Protection Logic
    Integrated software program interlock protection and mechanical hard limit dual safety design. When abnormal overload, motor stall or travel overrun occurs, the system immediately halts operation to protect drive parts and test samples. The enclosed test area prevents broken spring fragments from splashing out, improving lab operation safety.
  6. Simple Operation & Low Daily Maintenance
    Intuitive physical button operation interface without complex programming learning; new staff can finish parameter setting and specimen clamping within 3 minutes. The transmission part is equipped with long-life lubricating structure, only regular surface dust cleaning required, greatly cutting routine equipment maintenance workload for QC labs with daily batch testing.

Standard Complete Fatigue Test Workflow

  1. Parameter Pre-Setting
    Power on the control panel, input target reciprocating frequency, compression amplitude and total test cycle number according the elastic component’s technical specification, save parameter configuration for repeated batch testing.
  2. Specimen Fixed Clamping
    Open the test cabin, place spring/elastic workpiece on the bottom support platform, adjust upper compression pressure head height to fit the free state of the specimen, lock positioning knob to prevent offset during reciprocating cycles.
  3. Pre-Running Inspection
    Click manual jog mode to test 5–10 short reciprocating strokes, check whether the specimen shifts or collides with surrounding frame parts, adjust fixture position if abnormal.
  4. Full-Automatic Long-Cycle Fatigue Test
    Switch to automatic operation mode; the cam linkage drives the pressure head to perform continuous cyclic compression, the display screen synchronously shows real-time completed cycle counts. No manual monitoring required after startup.
  5. Automatic Completion Stop & Sample Inspection
    When reaching preset total cycles, the machine automatically stops and sounds alert. Open the cabin to take out the specimen, observe surface cracks, deformation or fracture condition to judge fatigue service life performance.
  6. Daily Equipment Storage
    After finishing all test batches, cut off main power supply, wipe dust on transmission and fixture surfaces, store spare fixtures in dry storage cabinet.
