Straightener: relates to a device for straightening wire before making process is finished the last one off the wire, the role played by definition is used to straightening the wire, but its role is not just straightening the wire, the following I said that his role is: 1: Check the steel quality, filtration steel surface cracks, center cracks, inclusions and some other quality defects. Filter broken wire (straightener Why can filter broken wires? It is because the wire itself due to the processing of raw materials and other reasons can not filter small impurities in the process because, after drawing the wire becomes finer, small impurities will cause broken wire, if you do not use the straightener, the fine will filter impurities can not afford, but in time to cut the wafer strength is insufficient to cause a broken wire. So we need to use straightening to filter tiny impurities, central crack , surface cracks. We look at pictures, our school has had two sets of straightening wheels straight, single set of unilateral side 3 side 4, corresponding to the wire pressed into a certain form pushing amount (so what will mentioned, straight adjust the amount of time must be pushed) wire at this pressure will be broken wire impurities, strong enough thing ...) 2: Control bead diameter, by changing the correction adjustment wheel aligner location, you can change the wire diameter circle. Adjust the ring with (a straightener 2 points, a diameter the size of the adjustment ring, an adjusting Alice head) 3: Eliminate stress (steel surface tensile and compressive stress, tensile stress straightener is to be changed to stress, increase wire fatigue)
