WDW microcomputer controlled wire and cable tensile testing machine (5-300KN)

WDW microcomputer controlled wire and cable tensile testing machine (5-300KN)

1、 Product Description:

The design of the WDW microcomputer controlled wire and cable tensile testing machine (5-300KN) adopts advanced control concepts from abroad, which meets the national standards GB/T228 "Tensile Testing Method for Metallic Materials at Room Temperature" GB/T7314 "Compression Testing Method for Metallic Materials at Room Temperature" GB/T14452 "Bending Mechanical Performance Testing Method for Metallic Materials" and can meet GB, ISO, ASTM, DIN and other standards. Other corresponding standards can be added according to customer needs. Beautiful appearance, easy operation, stable and reliable performance. The computer collects and controls data through the fully digital control system developed by Fangyuan Company, and directly controls the rotation of the fully digital speed regulating motor through the Fangyuan fully digital speed regulating controller. After the speed is reduced by the deceleration system, the crossbeam is raised and lowered through a precision screw pair to complete mechanical performance tests such as tensile and peeling of the sample.

The professional software of WDW testing machine automatically calculates the maximum force, tensile strength and other data. The control and data processing of the experimental process by the computer control system comply with the requirements of the corresponding national standards for metallic and non-metallic materials, and the test reports are diversified in various ways such as WORD, EXECEL, etc.

This machine has no pollution, low noise, high efficiency, and a wide speed range. This machine is suitable for testing the mechanical performance indicators of various metals, non metals, and composite materials, and fully meets the requirements of relevant national standards.

WDW microcomputer controlled wire and cable tensile testing machine for wire and cable tensile testing steps

1、 Test purpose: To test the tensile strength of wires and cables.

2、 Test scope: This testing method is applicable to various types of zippers.

3、 Test instrument: WDW microcomputer controlled wire and cable tensile testing machine

4、 Parameter requirement: Wire and cable tensile machine speed: 300mm/min

5、 Experimental steps:

1. The sample should be parked in the laboratory environment for more than 8 hours.

2. Cut three sections of wires and cables with a length of ≥ 75mm.

3. Start the power supply of the WDW microcomputer controlled wire and cable tensile testing machine, set the speed to 300mm/min. Place the sample device between the upper and lower fixtures, ensuring that the wire and cable feet are aligned tightly with the clamp of the fixture during installation.

4. Activate the testing key of the WDW microcomputer controlled wire and cable tensile testing machine. Start testing until the teeth come off or the yarn is damaged. Record the maximum tensile force during the testing process.

5. Each sample should be tested at least 3 times, and the average value should be taken as the final result.

6、 Result calculation or judgment:

Flat tensile strength (kg)=maximum tensile force (kg) * 25mm/width of tensile machine fixture (mm)

7、 Precautions for testing tensile strength:

1. If all three values are qualified, the average of the three values shall be taken as the final result.

2. If one of the three values is unqualified, two more samples should be cut for retesting. If there are still unqualified values in the retesting, it will be judged as unqualified, and the average of the unqualified values in the initial and retesting will be taken as the final result. If there are no unqualified items in the retest, all qualified numbers shall be taken as the final result.

3. If two or more of the three values are unqualified, they will be judged as unqualified, and the average of the unqualified values will be taken as the final result.
