Jan 21, 2016

 Bolt, with nuts cylindrical threaded fasteners. Is a machine part, usually fixed in the periphery of the mechanical equipment, so, over time, it is easy to rust. But how to remove the rusted bolts, becomes a technology. We know by head bolts and screws (with external thread of the cylinder) of two parts of fasteners, to cooperate with nuts, used for fastening the two parts with hole. This kind of connection form according to bolt connection. Such as screw the nut on the bolt, and can make the two parts separately, so the bolt connection is a detachable connection. So, bolt sophisticated detection, for how to remove the rusted bolts, has the vital role.

   Two kinds of bolt detection is divided into human and machine. Human is the most original and use the most common way of consistent detection. In order to minimize the bad product outflow, average production enterprise personnel treat packing or delivery of products by means of visual inspection, to eliminate non-conforming (bad tooth injury, mixing, rust, etc.). Another way for automatic testing machine, mainly is the magnetic particle inspection. Magnetic particle inspection defect of the leakage magnetic field is the use of bolt and the interaction of magnetic powder, bolts for possible defects (such as cracks, slag inclusion, mixing, etc.) permeability and steel permeability difference, these materials after magnetization of the magnetic field discontinuity battery change will occur, forming part of the magnetic flux leak occurs on the surface of workpiece leakage magnetic field, so as to attract the magnetic powder form of defect magnetic powder - magnetic mark, under the condition of appropriate lighting, showing defects location and shape, to observe the accumulation of magnetic powder and explanation, has reached to weed out the purpose of the defective product. I think, any a quality teacher, in the process of detecting bolts, if found a rusty bolts, their heart is how to remove the rusted bolts this problem has the clear answer. This is as a quality inspection division is the most basic technical requirements. Also hope these can be in your life, help you.
