Overview

The digital display ceramic tile flexural testing machine (hereinafter referred to as the flexural machine) uses a three-point bending beam test to reflect the mechanical properties of the material by measuring the flexural strength. It is mainly used to measure the flexural strength of ceramic tiles, tiles, and other materials. It is especially suitable for testing the bending strength of large-sized, high-strength ceramic tiles, and can also be used to determine the bending strength of brittle non-metallic material plates such as marble slabs and glass plates. This machine complies with the requirements for testing equipment in GB/T 3810.4—2006 "Test Methods for Ceramic Tiles—Part 4: Determination of Modulus of Rupture and Breaking Strength" and ISO 10545-4:1994 "Ceramic Tiles—Part 4: Determination of Modulus of Rupture and Breaking Strength." The machine features easy operation, stable loading, high measurement accuracy, and intuitive reading, making it an advanced method for studying the strength of related materials.

2. Worktable stroke: ≤70mm

3. Support roller and pressing roller radius R=15mm (externally covered with 5mm thick rubber)

4. Distance between two support rollers: 70–810mm

5. Power supply: 50Hz AC 220V±10%

6. Dimensions: 1150×850×1600(mm)

Structure Description

The flexural testing machine consists of the main unit and the digital display force measurement parts.

The main unit includes the loading system (driven by a motor with synchronous belt and pulley), base, worktable, support rollers, pressing roller, column, and sensor. The digital display force measurement part consists of a high-precision tension-compression sensor and a digital display controller. This part uses an electronic force measurement system with digital display of test results and features calibration, peak hold, and zeroing functions.

Working Principle

When ceramic tiles, tiles, and other brittle materials undergo a three-point bending test, if the test force is greater than or equal to the specimen's limit value, it will suddenly fracture. The maximum load F at the moment of fracture is used.

Installation, Debugging, and Calibration

1. Installation and leveling

(1) Leveling

After unpacking the testing machine, first check whether all pipe joints and connecting screws are loose. Then place the testing machine on a sturdy platform. Place a level on the worktable surface, support the four corners, and adjust to level.

(2) Reliable grounding of the testing machine

Use a copper wire with a cross-sectional area of no less than 1.5mm² to reliably ground the testing machine.

(3) Power on

Use a 50Hz, 220V AC power supply and check whether the sensor connection wires are properly connected.

[Preload Speed] Preload speed refers to the speed at which the fixture or sample is clamped before testing by setting clamping speed and force to achieve a stable clamping state with the testing machine contact surface.

[Specimen Width] Width of the specimen

[Initial Gauge Length] Specimen gauge length before starting the test

[Specimen Thickness] Thickness of the specimen

[Specimen Basis Weight] Mass per unit area

[Test Speed] Speed during the test.

[Fracture Judgment Force] The system judges fracture only after the applied force exceeds the fracture judgment force; otherwise, if the force does not exceed this value, the system considers the sample to be in a jitter interference period and does not judge fracture.

[Fracture Judgment Percentage] After the applied force exceeds the fracture judgment force and reaches a peak, due to force drop during fracture, when the force drops to a percentage of the peak value (e.g., peak force 100N, force drops to 80N), the system considers the sample fractured; this percentage is the fracture judgment percentage (e.g., 80%).

[Reset After Completion] Whether the crossbeam resets to the starting position after the test ends.

[Reset Speed] Speed of crosshead return.

[Reset Dwell Time] Time the crosshead stays before resetting after test ends.

[Advance Deceleration Displacement] Displacement when the crosshead is about to reach the test start position during reset.

[Cancel] Cancel input settings and revert to the values before setting.

[Save] After modifying parameters, click save. The system will use the modified values by default on next startup (otherwise changes will not be saved on shutdown).

1. Calibration

2.1 Calibration Selection (2-1) (The following calibration interface is provided for professional maintenance personnel; operating users can ignore)

Click the "Calibration" button in the main menu, enter the password "******" to enter the calibration selection interface as shown below

Calibration data is pre-calibrated by the manufacturer before shipment and does not need modification. Maintenance personnel can calibrate and modify.

[Displacement and Speed Calibration] Displacement and speed calibration; speed is calibrated simultaneously with displacement.

[Force Calibration] Calibration of the force sensor.

[Large Deformation Calibration] Calibration of the large deformation extensometer.

[Real-time Pulse] Real-time pulse count from the encoder or internal timer when moving up or down.

[Current Stroke] Real-time displacement amount

[Operating Status] Rising, descending, stopped

[Operating Time] Real-time operating time since the motor started running.

[Target Stroke] Displacement traveled by the motor from start to stop.

[Displacement Coefficient] Displacement coefficient value (automatically generated after correction)

[Speed Coefficient] Speed coefficient value (automatically generated after correction)

[Current Frequency] Change the "Current Frequency" to adjust the motor speed.

Stroke calibration process: First click "Reset" before calibration, then click "Up" or "Down" to let the press plate move a sufficient displacement, input this displacement value into the target stroke, then click "Correct", finally click save to complete the "Stroke Speed Calibration".

[Save] After calibration, click the "Save" button to save the data, otherwise the data will not be saved after the next power on.

2.3 Force Calibration:

Force calibration as shown in the figure (2-3)

[Number of Calibration Points] Number of force calibration points, up to 6 points can be calibrated.

[Zero Code Value] Code value at zero point.

[Real-time Force Value] Real-time value of the force sensor.

[Real-time Code Value] Code value corresponding to the force value used as a real-time variable for force calibration.

[Adjust Speed] Adjust speed when motor is rising or descending.

Force calibration process: First, select the number of calibration points needed, such as 5 points or 6 points, then modify the force value for each calibration point below the force value section. Click reset to ensure both the standard sensor and the sensor to be calibrated are at zero load. Click adjust to start at a speed of 10mm/min or another speed. Click up or down to slowly load the sensor. When approaching the first calibration point, click a smaller adjustment speed to slowly reach the first calibration point. Then click the "Calibrate" button behind it to complete the first calibration point. Repeat this process for all calibration points. After all calibration points are completed, click save to finish the calibration.

1. Configuration (3-1)

[Motor Reverse] Reverse the motor rotation direction (reverse the crossbeam running direction, changing the motor rotation direction will affect all test modes).

[Force Value Reverse] When the test force value is negative, you need to change the force value to a positive integer, otherwise the test curve cannot be drawn and no test results will be produced. The force sensor polarity is reversed (changing the force polarity in the current test mode will not affect the force polarity in other test modes. For example, if "Tensile Test" is selected in the test selection interface, and the force polarity is reversed in the configuration interface, only the tensile test force polarity changes, and bending test, compression test, and other test modes remain unchanged).

[Displacement Reverse] When the test displacement is negative, you need to change the displacement to a positive integer, otherwise the test curve cannot be drawn and no test results will be produced. Displacement polarity can be reversed. If negative displacement appears after starting the test, you can check the displacement reverse option in the configuration interface to change the displacement polarity. (Changing displacement polarity in the current test mode will not affect displacement polarity in other test modes).

[Force Value Acquisition Speed] During the test process, the sensor feedbacks the real-time speed to the acquisition board when under load (no need to modify, factory preset).

[Force Value Acquisition Bits] Force acquisition accuracy setting. If the sensor range is large, for example above 2T, you can set the acquisition bits to 18 or 20 bits to increase the bit count and improve force accuracy. After modification, the force sensor needs to be recalibrated (modification prohibited for non-debug personnel).

[Sensor Range] Maximum sensor range. You can also input a value close to the sensor range to protect the sensor from being damaged by compression or tension.

[Sensor Selection] If one sensor cannot meet the test requirements, four sensors can be equipped to meet different tests. Each sensor must have displacement and force calibration completed and saved separately (modify with caution).

[Displacement Speed Protection] This is the speed protection for the motor crossbeam's up and down movement. If the speed exceeds the set value, the motor will stop running. If displacement speed protection occurs during the test and the test stops, no test results will be produced.

[Displacement Source] Displacement source is the method of displacement counting, generally internal counting or encoder counting. Servo motors select encoder counting, stepper motors select internal counting (modification prohibited for non-debug personnel).

[Displacement Protection] When the set displacement protection value is exceeded, the motor will stop running and the test will be interrupted (modify with caution).

[Deformation Source] Deformation source is generally displacement or large deformation. When not using a large deformation sensor, select displacement as the source (operate with caution).

[Force Value Speed Protection]

[Motor Type] Servo motor and stepper motor. If displacement source selects internal recording, it is best to choose stepper motor. Stepper motors have a slow acceleration process at startup. If the device is equipped with a servo motor, this is not necessary (modify with caution).

[Next Page] Turn to next page.

[Cancel] Cancel input settings and revert to the values before setting.

[Save] After modifying parameters, click save. The system will use the modified values by default on next startup (otherwise changes will not be saved on shutdown).
