First, the equipment introduction
Pipe bending electronic universal testing machine, pipe four-point bending testing machine, large bending testing machine can carry out four-point bending test, unilateral force bending, local part for long materials such as whole beam, valve, steel pipe and galvanized pipe Compression test, water tightness, air tightness force test. Other test aids can be added for other test tests. Small load sensors can also be added to expand the measurement range.
WDW series electronic universal testing machine can be used for rubber, plastic, plastic, film, textile, nylon, fiber, nano material, polymer material, composite material, packaging tape, paper, wire and cable, fiber optic cable, safety belt, safety belt, leather Belts, footwear, tape, polymers, spring steel, bearing steel, stainless steel (and other high hardness steel), castings, steel plates, steel strips, non-ferrous metals, automotive parts, alloy materials and other non-metallic materials and metal materials Tensile, compression, bending, tearing, 90° peeling, 180° peeling, shearing, adhesion, pull-out force, elongation at break, and the like. Test parameters such as ReH, ReL, Rp0.2, Fm, A, Rm, E can be automatically obtained, and the test and data can be provided according to GB, ISO, DIN, ASTM, JIS and other international standards.
Second, the functional characteristics
(1) AC servo drive and AC servo motor, with stable and reliable performance, with protection devices such as overcurrent, overvoltage, overspeed, overload and limit.
(2) The control mode is divided into two forms: microcomputer control and manual control box control. The manual control box can be operated offline to reduce labor intensity and improve test efficiency.
(3) Test various stress-strain, force-elongation, force-time, intensity-time and other curves for curve comparison and image analysis.
(4) It can be equipped with different specifications of sensors, extensometers, large deformation, high and low temperature boxes and fixtures to broaden the measurement range and realize multi-purpose use.
(5) It can automatically store data, automatically identify, multi-control, retrieve previous test data and curve comparison analysis, and print test report.
(6) The electrical control circuit refers to the international standard, conforms to the national test machine electrical standard, and has strong anti-interference ability, which ensures the stability of the controller and the accuracy of the experimental data.
