First of all, let me introduce the function of disc spring to you:
The disc spring is a conical disc, which is different from the traditional spring and has its special function. Its main features are large load, short stroke, small space required, convenient combination and use, easy maintenance and replacement, and high economic safety. Suitable for precision heavy machinery with small space and heavy load. The optimum application range of its compression stroke is between 10% and 75% of its maximum compression stroke.
Disc spring characteristics:
Short journey and heavy load. ? The required space is very small. ? The combination is convenient to use. ? Maintenance and replacement are easy. ? High economy and safety.
Compared with cylindrical helical springs, disc springs have the following characteristics:
1, the load-deformation characteristic curve is nonlinear.
2. The disc spring is thin and easy to form components, which can be assembled and replaced with building blocks, bringing convenience to maintenance.
3. The disc spring with radial groove has zero stiffness. This characteristic can be applied to the field that requires the spring force to remain basically stable within a certain deformation range.
Close.
4. The vibration reduction performance of disc spring is not lower than that of cylindrical spiral spring. When the superposition combination is adopted, it has greater damping due to the friction between the disc springs and dissipates the impact energy.
Next, I'll tell you about the calculation of disc spring compression:
How to calculate and compress the spring? In a set of stamping dies, a large number of elastic materials are needed, including springs of different specifications, excellent adhesives, and? Nitrogen springs, etc. Choose different elastic materials according to different needs. Like bending and punching, using ordinary flat steel wire springs? Yes, such as brown spring, also known as brown spring; If the strength is not enough, add nitrogen spring, of course, the cost is higher; You Li glue is generally used for drawing dies, forming dies, or planes. The excellent glue used for wire drawing die is very good, and of course nitrogen spring can also be used.
Others like thimbles, sliders and dual-purpose needles? Generally, steel wire spring or yellow spring is used, as long as the material can be removed, the product is not pushed out of the mark, and the top is deformed. What are the characteristics of Youli glue? That is, the strength is relatively balanced, but the service life is relatively short, and it may crack, fail and wither after a period of production, so it is generally used less, and nitrogen springs are generally used. Use a lot of excellent adhesives for leveling. Springs include flat steel wire springs and steel wire springs. The function of the spring is to peel off and press the material, and the strength of the spring is small, which is related to the manufacture of the mold. Whether the production is smooth, whether the product is qualified, etc. The spring force is small, which may lead to the deformation of the product and the mold will not come off. Materials and products are not easy to take out from the mold, and some materials, knives and punches are easy to wear.
Flat wire springs are generally divided into brown, green, red, blue and yellow according to their colors, and their strength is also weakened in turn, with different colors. The amount of compression is different with different forces. There is a soil method to calculate the compression of springs, which was when I first entered the factory to learn molds, and I didn't know much about molds. My master taught me: measure the total height of the spring in advance, then lock the spring in a vice, then measure the remaining length of the spring after clamping with a caliper, and then subtract this number from the total length of the spring and divide it by the total length. This method is universal for any spring, for example, a brown spring with a length of 60mm is clamped in a vice. Subtracting 45.6 is equal to 14.4, and then dividing 14.4 by 60, the result is equal to 0.24, which is its compression.
According to the different production times of the spring, such as 6,543.8+0,000 times, 500,000 times and 300,000 times, the greater the compression, the shorter the life of the spring. The shorter the service life of the mold (of course, the spring can be replaced if it is broken), the spring may lose its strength after the mold is produced for a period of time. A poor quality spring may break in the mold. Generally, the compression of a spring is calculated according to 300,000 times, that is? After the die hits the spring 300,000 times, there may be no force. Of course, the life of general stamping die is not so long, and it can also be calculated according to the maximum compression. If calculated according to the maximum compression, only the spring can be guaranteed not to explode in the mold.
How about dying a little? But also is beneficial to that flatness of product. The specific compression amount is as follows: Color? Color? 100 times? 500 thousand times? 300 thousand times? Maximum compression brown spring? 16%? 18%? 20%? 24%? Green spring? 19.20%? 2 1.60%? 24%? 28%? Red spring? 25.60%? 28.80%? 32%? 38%? Blue spring? 32%? 36%? 40%? 48% dead? 40%? 45%? 50%? 58%? Maximum compression (how much this spring can press down), the maximum compression of the spring is equal to the free height of the spring multiplied by the maximum pressure difference ratio of the spring. For example, if the length of a brown spring is 60mm, its maximum compression is 60*24%, which is about 14. The maximum pressing force of this spring is 14 mm, and the maximum stroke is 14. The stroke of the die must be less than 14 mm, and more than14 mm. The spring may fail and deform, and may be interrupted in the die, or the die may explode and the punch cannot be pressed down. Before the mold is assembled, that is, before the mold is installed, it is necessary to calculate whether the compression of the spring is appropriate, so that you don't have to worry about the problems and explosion of the mold when trying the mold.
What is the compression of belleville spring? After reading the above, I think everyone should know that the compression of disc springs is not fixed, and each spring will have its own compression. We should master the calculation methods and influencing factors of these compression amounts, and only through these can we really calculate and measure the compression amount of belleville springs. I hope these words can help you know more about belleville Hot Springs, so as not to bring inconvenience to your life.
