Four,Aluminum bar tensile testing machine/Mechanical transmission sequence as follows:
Motor - Timing Belt Pulley - Ball Screw - Test Bench
4.2.2 Force Measurement System: A tensile sensor is mounted on the moving beam of the main unit, with its lower end connected to the upper clamp. During the test, the force on the specimen is converted into an electrical signal by the force sensor and input into the microcomputer acquisition and control system.
4.2.3 Automatic Extension Tracking Device: This device is used to measure sample deformation, consisting of two tracking clamps with minimal resistance that are held on the sample. As the sample is subjected to tensile force and deforms, the distance between the two tracking clamps also increases correspondingly. The tracking clamps convert linear motion to rotational motion through a rope and pulley, and the displacement is converted into an electrical signal inputted into the microcomputer acquisition and control system via a tracking encoder.
4.3 Limiting Protection Device and Clamp
4.3.1 Limiting Protection Device
The limit protection device is an essential component of this machine. The main unit is fitted with a limit rod, equipped with two adjustable collar rings that can move up and down. During the test, when the stopper and the collar ring make contact, it will cause the limit rod to move, enabling the limit device
Cut off the passage in this direction, the main unit will stop running. At this point, if you run in the opposite direction, the test machine will operate normally. Adjusting the position of the stopper on the limit rod can limit the travel of the moving beam, providing greater convenience and a more reliable safety protection for conducting experiments.
4.3.2 Jig
Our company offers a variety of universal and fixture holders for sample gripping, including wedge-type jaw fixtures, wrapped metal wire fixtures, film stretching fixtures, and paper stretching fixtures, among others. These are designed to meet the gripping requirements for various material tests, such as sheets, strips, foils, strips, wires, fibers, plates, bars, blocks, ropes, fabrics, and meshes, for both metal and non-metal materials. Custom configurations are available according to customer specifications.
FiveAluminum Bar Tensile Testing MachineInstallation and tuning
5.1 Mechanical Installation
Position the main unit vertically at the usage location, adjust the lower foot screws of the main unit, and check the workbench level using a level (longitudinal and lateral levelness of 0.2/1000).
5.2 Electrical Installation
5.2.1 Insert the force sensor plug into the force sensor interface and the displacement sensor plug into the displacement sensor interface.
5.2.2 Upon completion of the aforementioned tasks, the system can be powered on. There is a boat-shaped switch on the back panel of the microcomputer collection system. Place the switch in the 'on' position to connect the power supply.
5.2.3 Connect the main unit's power supply, then rotate to engage the pop-up power switch.
5.2.4 The microcomputer system must be preheated for 20 minutes after powering on before it can operate normally.

EightAluminum Bar Tensile Testing MachineCautionary Notes
8.1 Before powering on, check the connection lines, plugs, sockets, and power plug sockets between the CNC system and the main machine for correctness and tightness. Power on only after confirming they are correct (e.g., a loose ground wire under the power socket in the CNC system controller can cause the main machine to lose control). Always remember the power-on sequence: first, turn on the power of the test machine's main unit, then the CNC system power. When shutting down, turn off the power of the test machine's main unit first, then the CNC system power. Do not remove or insert any plug after powering on.
8.2 It's crucial to check the position of the upper and lower limit stoppers. Maintain a certain distance between the clamps to prevent damage to the machine parts due to misoperation or loss of control of the main unit, especially the sensors.
During the 8.3 test process, please do not press any keys on the microcomputer control system.
8.4 Select the fixture based on the specific test conditions to avoid damaging the fixture.
8.5 In case of a sudden power outage, please immediately shut down all power sources and restart them in order after confirming the stability of the power supply. Frequent and multiple interruptions in power supply are highly prone to damaging the microcomputer control system and the motor speed control system.
8.6 Do not stand far from the machine while the main unit is in operation.
8.7 The input tensile speed value must match the actual tensile speed of the testing machine, especially so for tearing and peeling tests.
8.8 Do not perform tensile tests when the breaking force value of the unclear sample is not specified; otherwise, the sensor may be damaged due to overload.
