introduction：61What is the effect of steel heating on steel bending？ a：The bending force required to heat the steel is reduced，The rebound phenomenon disappeared，The minimum bending radius is reduced，It is beneficial to control deformation according to processing requirements。 62：Under what circumstances is heating bending usually used？ a：Re-use at room temperature。 63：Why should the steel heating temperature be limited to a certain temperature？ a：Excessive temperature can easily cause overburning of steel，Too low a temperature will make molding difficult，And cause cold hardening。 64：When using contact bending，What measures are often adopted to solve the problem of refiring？ a：Modified mold shape，adopt

introduction：1New heating source In a new heating source，The heat source with high energy rate is the most eye-catching。The high energy rate heat source is mainly laser beam、Electron beam、Plasma arc, etc。High energy rate heat treatment is the use of high energy rate heat source to apply a very high energy density to the surface of the workpiece(10 3 ～10 8 w/cm 2 )，This results in a very fast heating rate(Can even reach10 11℃/s)，So in a very short time(1～10 -7S)，The surface layer of the workpiece to be treated is heated to a phase change temperature or molten state，Make physical and chemical changes，Then rely on the workpiece itself cold

introduction：Foreign low noise sealed bearings[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 is roughly divided into three categories：General purpose low noise motor bearing grease，Low temperature high speed bearing grease，High temperature long life low noise bearing grease。 1.General purpose low noise motor bearing grease In the bearing industry，The application of this grease

introduction：(1)The resultant force of the force passes as far as possibleIKOAxis of bearing，This requires the point of application to be uniform, symmetrical and stable，Force is applied through a sphere or parallel to an axis。 (2)The size of the force should be smooth and even，Not to be impacted，This requires the use of oil pressure or tools that can apply smooth tension or pressure，When the hammer had to be used，It should also be cushioned by softer, non-chipping metals such as copper sleeves，Knock as gently as possible。It is best to use a copper rod or copper hammer for hammering。 (3)Avoid applying force through rolling elements，This requires the inner ring to be installed and removed(Shaft ring)Apply force through the inner ring，When installing and removing the outer ring)Apply force through the outer ring
