Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern factories and professional spring manufacturer, selling products around the world. Spring classes thematic light spring is an ideal physical model, in the "Exam" involved in its knowledge points are: ① deformation and elastic, Hooke's law (which requires knowledge of grade B); ② potential bomb (A-level requirements), the spring force of the spring oscillator, etc. can not be mutated, it changes to go through a process, which is deformed by changing the spring to gradually carry out the decision. So, you know at a certain instant action (such as collisions) stretch will remain unchanged. Stretch is a variable force, while seeking impulses and elastic stretch of the work done by the butterfly spring, not directly with the definition of impulse and power spring, generally the amount of kinetic energy theorem and the theorem calculations. The spring force of the deformation is proportional to the change, so it causes the acceleration of the object, velocity, momentum, kinetic energy changes are not simply a monotonic relationship, tend to have a critical value. If the spring is used as an object within the system, the spring will not do within the system object does not affect the system's acting mechanical energy of the spring is very much useful Oh! Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Coned disc spring is a plate with a rectangular section spiral spring wound around the truncated cone, the conical coil spring which characteristic line is similar to the circular cross-section. The main feature is the small size, load, variable stiffness; widely used in small spaces, to bear the load of big occasions and shock absorber. Frustum spiral spring by spring parameters and carrying case classification, can be divided into a spring steel wire helix angle, etc., etc. pitch, and other stress three forms, namely: ① and other helix angle truncated cone spiral spring, ② pitch truncated cone, etc. spiral spring, ③ and other stress truncated cone spiral spring. The spring than in the design and manufacture of complex, commonly used materials are 60Si2MnA, 50CrVA, surface treatment methods are blue, painting and so on. Please specify when ordering free height, maximum deformation, maximum diameter, minimum diameter, maximum load, thickness, plate width, the working circle, total laps. We can according to your conditions of use, selection of suitable material, and satisfy your needs.
