I. Project introduction:
The domestic digital display electronic universal tester started in early 1990s. The Company is one of the companies that learn from foreign leading technology and research and develop electronic universal tester. To improve the technical level of the Company’s products, the Company has successively learned from advanced technologies at home and abroad, reaching a new high for the technical level of the Company’s products.
II. Scope of application:
The tester adopts TECO AC servo motor as power source; adopts advanced chip integration technology, and can test, analyze and study the mechanical properties of various metals, non-metals and composite materials. In addition, it is widely used in aerospace, petrochemical engineering, machinery manufacturing, wire, cable, textile, fiber, plastics, rubber, ceramics, food, pharmaceutical packaging, polyethylene-aluminum composite pipeline, plastic doors and windows, geo-textile, film, wood, paper, auto parts, metal materials and manufacturing.
III. Key description:
1. Host: The machine adopts a gantry floor-type double-spaced structure, pulls up and pushes down, regulates the speed steplessly by lifting and lowering the beam, and can change the test space after the replacement of uprights, lead screws and outer cover. The transmission system is composed of low-noise arc synchromesh gear belt deceleration system and lead screw pair, which is characterized by stable operation, high efficiency, low noise and no pollution.
2. Standard configuration: A pair of lever-type stretching attachments. The lever-type stretching attachments adopt the manual clamping method, making it convenient and reliable to clamp without slide. The jaw remains immobile and the clamp part moves up and down in the clamping process. In addition, the sample is free from additional force, ensuring the accuracy of test results.
3. Wedge-shaped tensile fixture: Either horizontal vice jaw: 0-7mm (optional: 7-14mm) or round jaw:￠4-9 (optional: 9-14mm)
4. A set of compression attachments: Diameter of compression plate: 100mm
Automatic calibration: The system can automatically calibrate the scale value.
In the entire test process, the big LED displays the test force, peak value, displacement, speed and status in real time.
Breaking judgment: The movable cross-beam automatically stops moving after sample breaking.
Position limitation protection: It has the function of position limitation protection at machinery and control levels
