The main purpose, functional characteristics and requirements of the experimental environment of the digital display tensile testing machine

　　 digital display tensile testing machine is also called tensile testing machine, electronic tensile testing machine, universal material testing machine, material tensile testing machine, etc. Provides two sets of capacity test spaces, allowing operators to have a greater range of use, especially when the strength gap between raw materials and finished products is large. The floor type is used in the type, which is most commonly used in industries such as steel wire and small screw fabrics. Use. The maximum test force is 50KN, long stroke and two test spaces. Two sensors of different capacities can be installed. It can be used in occasions where the test force is very different, such as in the spring industry, steel wire industry, rubber and plastic industry. Analysis and testing of other materials.　　 The development of science and technology promotes the improvement of productivity, the market demand for precision electric meters will tend to shrink, and the overall demand for portable electric meters will also decrease. The requirements for the special tensile testing machine products mainly focus on the appearance of the instrument, the structural design, the expansion of the application field, and the improvement of reliability. The focus of the development of digital instruments is to improve reliability. So what are the main purposes, functional characteristics and requirements of the experimental environment of the digital display tensile testing machine? Here is an introduction: 　　1. The main purpose of the digital display tensile testing machine: 　　 The tensile testing machine is suitable for rubber, plastic, For tensile tests of textiles, waterproof materials, wires and cables, mesh ropes, metal wires, metal rods, and sub-boards, compression and bending tests can be done with additional accessories. It has the functions of digital display of test force, continuously adjustable test speed, automatic shutdown when the sample is broken, and peak value hold. 2. The functions and characteristics of the digital display tensile testing machine: 　　 1. The high-precision, fully digital speed control system and precision reducer are used to drive the precision screw pair for testing to achieve large-scale adjustment of the test speed, low noise during the test, and operation smooth.　　2. The universal joint adopts a cross pin structure and has a swing angle restriction function. On the one hand, it is convenient for sample clamping and ensures the concentricity of the test. On the other hand, it eliminates the influence of irregular samples on the sensor.　　 3. Touch key operation mode, real-time LCD display. The display interface can display the test method selection interface, test parameter selection interface, test operation and result display interface and curve display interface, which is convenient and quick.　　4. The beam can be adjusted quickly and slowly when the specimen is clamped, and it has protection devices such as overcurrent, overvoltage, and overload. .　　5. It is equipped with a microcomputer interface, which can be connected with a microcomputer to realize the control of the test process and the storage and printing of data. 3. The requirements of the digital display tensile testing machine for the experimental environment: 　　 1. The laboratory space must be larger than the size of the digital display electronic tensile testing machine itself, like the vertical digital display electronic tensile testing machine model, such as the test space is 3 meters For the ring stiffness testing machine, in order to facilitate the test and placement, the laboratory space should be at least 4 meters; and for the horizontal digital display electronic tensile testing machine products, because of its unique test space requirements, the laboratory space must meet Dozens of meters. 2. The humidity of the thermometer in the laboratory must be controlled within a certain range. If the test temperature is too high, the frequency of failure of the motor and sensor of the test equipment will increase. If the indoor humidity is too high, it will cause the equipment to malfunction. Rust, in short, if there is no special requirement, all material mechanics testing standards stipulate that the room temperature is within the range of 10℃-35℃, and the relative humidity is not more than 80%. 3. The ground where the digital display electronic tensile testing machine is installed should be flat and stable. If it is not flat, the digital display electronic tensile testing machine will inevitably have a certain inclination, so the upper and lower clamps of the clamp cannot be kept coaxial. Degree, will have a great influence on the test results.　　4. The power supply voltage in the laboratory should be stable, and it cannot fluctuate too much back and forth, just like household appliances. If the voltage fluctuates too much, the appliance will switch back and forth, which will cause the appliance to malfunction. The usual fluctuation control range of equipment like digital display electronic tensile testing machine should not exceed ±10% of the voltage. 5. Corrosive media around the digital display electronic tensile testing machine is not acceptable. After all, the test equipment is metal products. Once the digital display electronic tensile testing machine is damaged, it will reduce the strength, plasticity, toughness and other mechanics of the metal material. Performance 6. The laboratory where the digital display electronic tensile testing machine is located must not have vibration. If the test is done, the vibration will affect the test data, and if it is in this condition for a long time, it will cause sensors and encoders. And other sensitivity.　　 The above is an introduction to the main purpose, functional characteristics and requirements of the experimental environment of the digital display tensile testing machine. When using the test press, the operator must use it in accordance with the process specification in the manual. Otherwise, it is easy to cause dangers such as machine failure and personal injury.
