Overview
Puyun brand PY-J633 series paper Cardboard film three-point bending stiffness tester is a multi-functional stiffness tester, mainly used for the measurement of Cardboard, color boxes (such as cigarette packs, cosmetic boxes) Che force (ie 90 degree crease rebound force), is the basic instrument for paper and Cardboard flexural strength performance detection. The instrument adopts vertical, multi-column structure, adjustable chuck spacing, large tensile stroke, smooth operation, high test accuracy, suitable for paper, Cardboard, paper core, plastic, film and Miscellaneous Non-metallic materials.
Features
1. Adopting a vertical, multi-column structure, the chuck spacing can be arbitrarily set within a certain range.
2. The stretching stroke is large, the up and down running is smooth, and the test accuracy is high.
3. Equipped with multiple protection devices, including mechanical travel switch, emergency stop switch, electrical protection, software limit, breakpoint stop and emergency braking function.
4. High Accuracy Force Sensor, High Accuracy Variable Frequency Motor, High carbon steel forging link plate and precision ball screw to ensure stable performance.
5. The fixture adopts hard chrome Eletroplating treatment, Hardness is high; the surface of the body adopts electrostatic spray painting process, which is resistant to fading.
Principle
The testing machine works based on the principle of three-point bending test. The precision ball screw is driven by the High Accuracy frequency conversion motor, which drives the movement of the transmission link and the fixture, and applies a vertical load to the middle of the sample placed on the two support points to bend it. The High Accuracy Force Sensor real-time measurement of the force value change during bending, so as to calculate the performance parameters such as the anti-bending stiffness or Cong force of the material.
Applications
Paper, Cardboard, Paper Core, Plastic, Film, Miscellaneous Non-metallic Materials
Standards
GBT 22906.6-2008、GBT 23144-2008、GBT 1449-2005
Steps
1. According to the sample specifications, adjust the spacing between the two support fixtures.
2. Place the specimen flat on the two support clamps.
3. Set the test speed and other parameters through the control panel or software.
4. Start the test, and the indenter moves downward to apply a load to the middle of the sample until the sample is bent or reaches the set conditions.
5. The equipment automatically records and displays data such as force value and displacement, and calculates stiffness or related performance indicators.
6. After the test is completed, return the indenter to its initial position and remove the sample.
Notice
Before testing, make sure the equipment is placed horizontally and firmly.
• According to the sample material and standard requirements, correctly select and install the appropriate fixture.
When setting parameters, do not exceed the maximum range and travel range of the equipment.
When placing the specimen, ensure that its center is aligned with the indenter and is flat and free of wrinkles.
• During operation, it is strictly forbidden to extend your hands or Miscellaneous parts of the body into the area of the fixture and moving parts.
• In case of emergency, press the emergency stop switch immediately.
• Regularly clean and maintain the equipment to check whether the components are normal.
• Non-professional personnel should not disassemble or repair the internal electrical and mechanical components of the equipment.
