spring manufacturer in china

Spring manufacturers of so-called torsion test is the ends of the materials that are going to test in accordance with the wire diameter between 100 times, each with a fixed doesn't make the shift and taut, and then make the spring manufacturer Return to cut off at the end of one of, calculate the torsion times and check of its status and torsion condition, if between both ends fixed more than 100 times the wire diameter, the reverse Number, according to the length of which proportional increase and decrease, this can be in accordance with 100 times the wire diameter of torsional frequency conversion, spring factory was in a bending test, the material along its at both ends Diameter into the radius of circular arc with an Angle of 90 degrees bend, make the second point in different directions, then check the surface condition.Spring manufacturers Commonly used piano steel wire - also known as SWP, in the spring steel is good material, spring wire must after processing factories require production line up at a room temperature,Then make surface grinding processing, surface line must be come true in practical circle, the surface is smooth and shiny, no scar or other faults, wire through the parallel test,Can't produce cracks, and when the bending test by hand, the number should be 2 times, spring manufacturer for parallel test is place the wire to the slide plate, with 1 lb The hammer of the line into 1/2 thickness of wire diameter, manual bending test is to use special edge below 0.2 mm (R) of iron clamp force compaction, then bent 90 degrees, then Restorable.Spring manufacturers
