The Jiangdu Jinguo Tensile Machine mainframe is composed of an electric motor and controller, ball screw, guide column, moving crossbeam, limit device, etc. The sequence of mechanical transmission is as follows:
Motor - synchronous belt pulley - screw - test bench
4.2.2 Force Measurement System: A tensile sensor is installed on the moving beam of the main unit, with its lower end connected to the upper clamp. During the test, the force applied to 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 low-resistance tracking clamps that hold the sample. As the sample is subjected to tensile force and deforms, the distance between the two tracking clamps also increases accordingly. The tracking clamps convert the linear motion into rotational motion through a rope and pulley, and the displacement is then converted into an electrical signal inputted into the microcomputer acquisition and control system by a tracking encoder.
4.3 Limiting Protection Device and Clamping Jig
4.3.1 Limiting Protection Device
The limiting protection device is a crucial component of the machine. The main unit is fitted with a limiting rod, which is equipped with two adjustable rings that can move up and down. During the testing process, when the stopper comes into contact with the ring, it will drive the limiting rod to move, enabling the limiting device
Cut off the passage in this direction, the main engine will stop running. At this point, running in the opposite direction will allow the test machine to operate normally. Adjusting the position of the stopper on the limit rod can limit the travel of the moving beam, providing great convenience and a safe and reliable protection for conducting tests.
4.3.2 Fixture
Our company offers a variety of general and specific holding fixtures for sample clamping, including wedge-type jaw fixtures, wrapping metal wire fixtures, film stretching fixtures, and paper stretching fixtures, etc. These are capable of meeting the clamping requirements for performance tests on various materials such as metal and non-metal sheets, strips, foils, bars, wires, fibers, plates, rods, blocks, ropes, fabrics, and nets, and can be customized according to customer specifications.
5. Installation and Debugging
5.1 Mechanical Installation
Position the main unit vertically at the point of use, adjust the lower foot screws of the main unit, and check the workbench level with a level (longitudinal and lateral levelness 0.2/1000).
5.2 Electrical Installation
5.2.1 Plug the force sensor connector into the force sensor interface and the displacement sensor connector into the displacement sensor interface.
5.2.2 Upon completion of the aforementioned work, 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 activate the power supply.

8. Cautionary Notes
8.1 Before powering on, check the connections between the CNC system and the main unit, including cables, plugs, sockets, and power plug sockets, to ensure they are properly connected and not loose. Confirm that everything is correct before powering on (e.g., a loose ground wire under the power socket in the CNC system controller can cause the main unit 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 any plug after powering on.
8.2 It is crucial to check the position of the upper and lower limit position bushes, ensuring a certain distance between the two clamps to prevent damage to the machinery due to misoperation or loss of control of the main unit, especially the sensors.
During the 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 Sudden power outage: immediately shut down all power sources and restart in order after confirming stable power supply. Frequent and multiple interruptions in power supply can easily damage the microcomputer control system and the motor speed control system.
8.6 Do not stand too 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 during tearing and peeling tests.
8.8 Do not perform tensile tests when the breaking force value of the unclear sample is not specified, as it may damage the sensor due to overload.
