In convex screw compression special-shaped
spring due to the small spring ring on both ends can be embedded into the circle in the middle, and so the larger deformation can be obtained.
For example, some of the convex type auto brake spring, and has been in a tight state at ordinary times, open the car valve, spring back deformation, drives the brake of automobile brake.
Haircut convex pusher is also used in helical spring this characteristic, the effective space to obtain larger deformation and stress.
special-shaped spring through what to get metal protective layer:
metal cover a lot of more phyletic, in terms of special-shaped spring, usually use the method of plating for metal protective layer.
Plating layer can not only protect from corrosion, and at the same time can improve the appearance of the special-shaped springs.
Some electroplating metal also can improve the working performance of special-shaped spring, such as to improve the surface hardness, increased wear resistance, improve the thermal stability, prevent rays, corrosion, etc.
But if it's purely for the sake of special-shaped spring corrosion, generally choose the electricity galvanized layer with cadmium plating layer.
Zinc nickel plating special-shaped spring is stable in dry air, almost no change, is not easy to change color.
In humid air will generate a layer or carbon zinc carbonate white film.
This layer of dense membrane can prevent corrosion continue to suffer.
So the galvanized layer for special-shaped spring under the condition of atmospheric corrosion protection layer.
All contact with sulfuric acid, hydrochloric acid, caustic soda solution phase, and in the moist air in the atmosphere in the sulphur trioxide of special-shaped spring, unfavorable use zinc plating.
spring available monolithic spring steel plate or multichip superposition, the cushioning and vibration damping performance is good, especially more plate spring vibration isolation performance is strong, it is mainly used for automobile, tractor and railway vehicle suspension.
in the limited space, often with rectangular section materials of the spring, because spring made of rectangular section materials can be in the same space and obtain larger load under the same deformation.
This kind of spring compared with the material of the spring with circular cross section, in the same space, its cross-sectional area is large, so it absorbs energy is also big, it can be used in heavy machinery, stamping die or special big spring stiffness.
Nowadays, it is very common for us to utilise in leaf spring hardware. And the quality of is decisive to production efficiency.
All of the experts Dongguan Yongqiang spring hardware Co.,Ltd. consulted stressed that the best recovery plans are the ones made before you need them, not afterward.
We should take a step back to review how Yongqiang approach tracking, implementing, and communicating compliance-related changes and attempt to identify areas of improvement in their processes.
To find a qualified at reasonable price, contact Dongguan Yongqiang spring hardware Co.,Ltd. at Yongqiang Spring Hardware, a professional provider and tell them what you envision for your News.
Many of the News listed here can be purchased for less money, but in general we recommend paying a slightly higher price for significantly improved performance. These are our top choices and their recommended configurations.
