Show that the first compressed spring reaches normal compression limit when end, top board presses mechanical switch at this time, to make warning device
Start to alarm, operating personnel is reminded to handle；In addition, mechanical switch is also electromechanical with the electric rotating of drive bottom plate rotation in pedestal
Connection, after mechanical switch is pressed, electric rotating machine drives bottom plate rotation, to make center platen that can be moved down along outer barrel, make the
The force-applied compression of two compressed springs reduces the time that the first compressed spring is in normal compression limit to the greatest extent, extends spring branch and hangs
The service life of frame；
（4）In the present invention, there are four bar shaped sliding slot one is uniformly arranged along outer tube side wall, make top board and center platen downwards or to
Balance is more preferable when upper movement, and the first compressed spring and the second compressed spring will not occur partially during compression or elongation
It moves,；
（5）In the present invention, C is added in the raw material of spring, C can effectively improve the intensity of steel, to improve spring
Load capacity, still, the too high levels of C can cause decarburization during steel strand, can deteriorate the toughness of spring instead, therefore will
The content of C is controlled in 0.58-0.63%；Cu is added, Cu elemental stables are not easy to be aoxidized, can improve the corrosion resistance of spring
Energy；Ni is added again, the quenching degree of steel can be improved, ensures that alloy solution obtains martensitic structure after solid solution is cooling；Si is added,
As the main contribution element of spring steel elasticity, the elasticity of spring is effectively increased, to improve the stiffness factor of spring；Add
Entering Cr, the quenching degree of steel also can be improved in Cr, can also refine structure of steel, to improve the intensity of spring, meanwhile, Cu, Ni, Cr are same
When melting when can form the fine and close and very strong amorphous state spinel oxides protective film of compactness in steel surface, due to this layer
The presence of dense oxidation film prevents oxygen and water in air to be penetrated into matrix, slows down the corrosion rate of corrosion, substantially increase
The corrosion resistance of spring；It is additionally added Nb, can be reacted with C and generate NbC, play the role of crystal grain thinning, at the same time it can also prevent
Cr elements form carbide to reduce content of the Cr elements in crystal boundary with C element, avoid grain boundary corrosion；Mn elements can be improved
Corrosion resistance of the steel in organic acid；
（6）In the present invention, the heat treatment process being tempered after being quenched to manufactured steel makes the pearlite group of austenitic formation
It knits and is more uniformly distributed, avoid the formation of not exactly the same tissue, there is a phenomenon where brittle crackings to prevent manufactured spring；
（7）In the present invention, chromate processing is first carried out to manufactured spring, then immerses spring containing ultra-fine flake zinc
It in ethylene glycol solution, then toasts, falling solution, later secondary baking, spring surface is made to form one layer of zinc-chromium coating, this layer of coating
With very high heat resistance, heat resisting temperature is up to 300 DEG C, and the corrosion resistance of the coating is extremely strong, and in addition there are no hydrogen
Brittleness is more suitable for this stressed member of spring, the service life of spring is made to extend 40-60%.
