introduction：Button position ( Snap Joints ) Basic design principles Fastening provides a convenient and economical method of product assembly，Because the combination part of the buckle is formed at the same time when the finished product is produced，No other screws are required during assembly、Muons and other locking accessories，As long as the two sides of the buckle to be combined with each other can be fastened. The buckle can be designed in a variety of geometric shapes，But the principle of operation is much the same：When the two pieces are fastened，The hook protruding part of one of the parts is pushed away by the flange part of the connecting part，Until the flange part is finished；And later，By the elasticity of the plastic，Hook extension

introduction：one:bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Grease flow： 1. When the grease is not subjected to external force，It can hold a certain shape like a solid，That is, it does not automatically lose when it is stationary。 2. Under extremely high shear stress（High cutting speed），Greases flow like Newtonian fluids，Viscosity energy

introduction：1．water Water is the earliest application、broadest、The most economical quenching medium，It is cheap and easy to get、non-toxic、Not burn、The physical and chemical properties are stable、Strong cooling capacity。By controlling the temperature of water、Increase pressure、Increase velocity、Use circulating water、Using magnetic field action, etc，Can improve the cooling characteristics of water，Reduce deformation and cracking，Better quenching effect is obtained。However, these methods require additional specialized equipment，And the performance of the workpiece after quenching is not very stable，So it has not been widely used。so。Pure water is only suitable for a small number of low carbon content、For quenching steel parts with low hardenability and simple shape。
