What are the requirements for the clamp when the steel wire pulling machine stretches the copper wire? Rally machine to test different samples when the requirements are not the same, of course, the fixture is not the same, then, the steel wire tension machine when the copper wire is stretched when the folder has what requirements? The following engineers from Haida analyze it for everyone:
Based on the use and characteristics of various tensioning machine fixtures in normal work, we have developed ideal winding fixtures and circular fixtures suitable for small diameter (less than 2mm ) wire detection. Below we briefly explain the design of 0-0.8mm and 0.8-2mm wire tension fixtures.
1 、 Small size steel wire test
1 ) Wires with a diameter of less than 0.8mm use a winding jig. First, the sample is rotated on the upper fixture around the cylinder, and then the sample is fixed with two pieces of a splint made of soft metal (such as copper, aluminum, etc.) or hard rubber.
2 ) The clamping method of the lower jig is the same as that of the upper jig, and finally the sample is fixed between the upper and lower jaws of the pulling machine. The gauge length is determined according to the test method or product specifications, and then the tensile test is performed.
3 ) Result The test specimen fracture position is almost 100% falling on the gauge length part, greatly improving the test success rate, thus ensuring the accuracy of the test data.
2. Wire test with a diameter of 0.8-2mm
1 ) The steel wire tensile test with a diameter of between 0.8mm and 2mm uses a circular jig to hold the sample directly in the upper and lower jigs. Using a circular jig, the jig does not need to be wound by bite.
2 ) The test method is the same as the small-scale steel wire test. If the gauge distance is set to be stretched, the result is broken at the gauge distance, which is ideal.
What are the requirements for the clamp when the steel wire pulling machine stretches the copper wire? The above is the fixture requirements analysis when the wire is stretched, do not know if there is a solution to your doubts, if you need to learn more about copper wire pulling machine related information.
