Analysis of the Causes of Insufficient Spring Elasticity

In view of the development of the current mold spring, the mold spring is divided into a metal spiral mold spring and a nitrogen mold spring. Metal mold spring: Made of imported alloy spring steel, the quality is no different from the American DANLY mold spring and the Japanese Datong mold spring.

In view of the development of the current mold spring, the mold spring is divided into a metal spiral mold spring and a nitrogen mold spring.

Metal mold spring: Made of imported alloy spring steel, the quality is no different from the American DANLY mold spring and the Japanese Datong mold spring, but the price is about 40% lower. Widely used in molds, fixtures, industrial clutches, brake components and various mechanical components.

Nitrogen mold spring: The domestic manufacturing quality has reached the international level, the price is about 50% lower. The nitrogen mold spring can be exchanged with the nitrogen mold springs of Dadco, Kaller, Misumi, Hyson, Boding, Quiri and other brands. The delivery time is short and the service is fast.

The mold spring generates a mechanical clock and a clockwork toy under the action of external force. When the clockwork we know, the role of the car frame and the car is to tighten the staples on the one hand, the role of the staples on the one hand, and the top of the staples, on the one hand. The state can be restored by tightening the spring.

The reasons for the lack of elasticity of the mold spring are:

1. The spring quality level is wrong: the unintentional or deliberate use of the ordinary spring as a high-quality spring or an imported spring, resulting in insufficient feeling of elasticity.

2. Non-standard spring design parameters are unreasonable: only focus on the outer diameter, inner diameter, length and other parameters, often overlooking the cross-sectional area of ​​the wire and the size of the pitch, resulting in insufficient elastic force.

3. The standard spring selection is unreasonable: because the figure is cheap, the lighter load type is selected and the heavy load cannot be tolerated, resulting in insufficient feeling elasticity.

4. The spring wire itself is soft, or the spring quenching temperature is low or the holding time is not long enough, or the tempering temperature is too high and the time is long after the spring is formed, so that the tensile strength is insufficient and the elastic force is insufficient - this is the true meaning The elasticity is not enough.

5. Exceeding the specified temperature causes the elasticity to decrease or even lose its elasticity.

Musk Ambrette is a nitromusk once in common use, but now widely-regarded as toxic. Nitromusks are a group of synthetic fragrance chemicals typically used in cosmetics, perfumes, air fresheners, cleaning products, detergents, soap, and many other everyday products with artificial scents. Exposures to nitromusks in the general population are widespread, due to their presence in this broad variety of consumer goods.
