Product Overview

The KR‑206 vertical computer‑servo universal tester integrates high‑precision mechanical transmission and digital electronic measurement technology. It delivers stable closed‑loop control for loading force and moving speed, offering outstanding measuring precision for force and displacement signals. It supports constant‑rate loading as well as constant‑rate displacement test modes. Available in 100 kN, 200 kN and 300 kN capacity variants, this floor‑standing unit evaluates mechanical behaviours for both metallic and non‑metallic specimens under 30‑ton load. Fully compliant with GB/T 16491‑1996 requirements, it fits production‑line quality‑control, product‑R&D and laboratory certification tasks.

It completes tensile, compression, bending, shear, peel, tear and two‑point extension assessments for rubber, plastics, cable products, safety‑belt webbing, composite fabrics, waterproof sheets, copper‑steel profiles, spring steel, bearing steel, stainless‑steel parts, castings, metal strips and non‑ferrous metal wire. It gains wide adoption in manufacturing workshops, metallurgical plants, automobile factories, university material‑science labs and third‑party inspection‑arbitration agencies.

Core Product Competitive Advantages

1. High‑Rigidity Double‑Column Vertical Frame Heavy‑duty welded steel vertical frame minimizes frame deflection under high‑load conditions. The cross‑head supports jog fine‑tuning plus fast‑speed home return after tests. Multiple optional tensile stroke sizes are selectable, and customized larger travel dimensions are available for extra‑long work‑pieces. Four adjustable leveling feet guarantee stable placement on uneven lab floors.
2. High‑Accuracy Measurement & Acquisition Unit High‑resolution photoelectric encoder captures displacement data. The embedded micro‑controller handles measurement, control logic, arithmetic and data storage all‑in‑one. Force sensor provides constant resolution of 1/200 000 full‑scale. An external extensometer can be added to obtain precise elongation and elastic‑modulus values for high‑accuracy material‑characteristic calculation.
3. Feature‑Rich Windows‑Based Test Software Pre‑built test templates cover GB, ASTM, DIN, JIS, BS and other international testing norms. Operators store custom product‑specification profiles for repeated batch testing. Editable report outputs support native Excel export. Multiple real‑time curve types are rendered: force‑displacement, force‑time, displacement‑time, stress‑strain and two‑point‑extension graphs. Post‑test functions include curve zoom‑in, overlay and comparative analysis. The program automatically computes tensile strength, upper/lower yield strength, non‑proportional extension strength, breaking elongation, elastic modulus, peel‑force statistics and total absorbed‑energy. Force‑and‑length measurement units are fully interchangeable: N, kg, lb, ton, mm, cm, inch. Test datasets can be saved onto local disk folders for future review.
4. Multi‑Layer Electronic Safety Interlock Mechanism Electronic upper‑and‑lower travel limit stops prevent cross‑head mechanical collision. When applied load goes beyond 110 % of rated sensor capacity, automatic overload‑protection cuts movement to safeguard the precision load‑cell. Users can choose manual‑triggered or automatic high‑speed home‑return after finishing each test run.
5. Expandable Fixture & Sensor Options Standard configuration includes universal tensile jaw set for round‑bar specimens up to Φ30 mm and flat samples with maximum thickness 25 mm. Peel, bending, shear and special‑shape custom jigs can be ordered separately. Multiple interchangeable load‑cells may be fitted to broaden the effective measuring scope for diversified‑load sample batches.

Standard Complete Test Operating Workflow

1. Equipment Inspection & Parameter Configuration Power‑on main unit and supporting computer; launch dedicated test software. Select or create test procedure matching target material standard; define termination conditions and report‑template settings.
2. Specimen Mounting & Alignment Use jog‑mode to adjust cross‑head position; firmly fasten test‑piece inside matching fixture and ensure perfect axial alignment to eliminate eccentric‑loading influence. Mount external extensometer (if required) onto specimen gauge‑length section.
3. Pre‑Test Zero‑Calibration Perform force‑value and displacement zero‑reset to clear initial mechanical offset.
4. Automatic Test Execution Start test sequence. Servo‑driven cross‑head travels at preset velocity; system continuously captures force, displacement and deformation data and draws real‑time test curves.
5. Post‑Test Data Review & Report Export After specimen fracture or reaching pre‑set stop criteria, test terminates automatically. Review key characteristic‑point data, zoom and overlay curves; export datasets into Excel or print formal inspection reports.
6. Equipment Shutdown Steps Cross‑head returns to home position; remove broken specimen and wipe fixture surfaces clean. Close software program and disconnect main power supply.
