Hexagon socket bolts are generally used to fix parts on mechanical equipment. Since mechanical equipment needs regular maintenance and repair, repeated disassembly also causes some wear on the inner corners of the socket bolts. It is difficult to remove them with tools over time.Today, the hexagon head bolts will show you how to disassemble the hexagon socket bolts to reduce the wear of the hexagon socket.
For the connection where the head of the hexagon socket bolt is slightly higher or flat than the plane of the fixed part, a hexagon nut with a slightly smaller outer diameter than the head of the hexagon socket bolt can be used to put it on the head of the hexagon socket bolt, and then connect the nut to the hexagon socket bolt. The heads are spot welded together. After cooling, use the movable hand to twist the nut to take out the hexagon socket bolt.
Generally, threaded connections are self-locking, and will not loosen automatically when connecting stationary objects and the working temperature does not change much.However, under shock, vibration or variable load, and when the working temperature changes greatly, this connection may loosen, affect work, and even cause accidents.In order to ensure reliable connection, effective anti-loosening measures are taken for threaded connection when installing bolts.
The commonly used anti-loose measures include three categories: mechanical anti-loose, increased friction and non-detachable.
(1) Use various stop parts to prevent the relative rotation of threaded parts to achieve anti-loosening. This technology is called mechanical anti-loosing, which is more reliable, so it is widely used.Commonly used mechanical anti-loosening measures include split pins and slot nuts, non-return washers and round nuts, stop washers and nuts, and Shenlian steel wire.
(2) Increase friction by installing spring washers and using double nuts.This kind of anti-loosening technology can prevent the tightened threads from losing pressure due to external load changes, so there is always frictional resistance to prevent the connection from loosening.
(3) Use tack welding, spot riveting and other methods to fix the nut on the bolt or the connected part, or fix the screw on the connected part to achieve the purpose of anti-loosening. This anti-loosening measure is not removable.
I briefly shared with you how to reduce the disassembly, wear and maintenance skills of hexagon socket bolts. I hope it will be helpful to you in daily maintenance.
