How to choose shaped spring manufacturers

Problems that should be noticed by manufacturers when choosing shaped spring in spring design:

1. How to choose the shaped spring? To solve such problems, we usually need to consider the pressure size, stroke, the number of special-shaped springs and the boost ratio of special-shaped springs.

(1) Selection of spring pressure: Select the number and type of special-shaped spring and spring pressure of each special-shaped spring according to the calculated impact pressure. Generally speaking, it is more in line with the actual situation to select the spring pressure according to the calculated impact pressure plus 15%-20% increment. Because first, when the die wear, there will be gap change. The change of technological parameters such as blunt edge, the inconsistency of mould thickness and deformation resistance of mould plate will cause the change of deformation resistance of workpiece, so the deformation resistance should be left in the design. Second, shaped spring in the air, high pressure gas is bound to have throttling loss, so that the elastic force to float. Third, the life of special-shaped spring is very long, after a period of use, the high-pressure special-shaped will have a certain leakage, resulting in a slight drop in bomb pressure.

(2), the selection of the number of special-shaped springs: according to the sex demand, combined with the mold structure and the position of the force point, so that the mold will not appear the phenomenon of off-load when working, but also must make the mold adjustment convenient. In this way, shaped spring in the use of the Chinese side can have enough life.

(3), the selection of charging ratio of special-shaped spring: the type of special-shaped spring can be determined according to the characteristic curve of special-shaped spring and the requirements of stamping process. In particular, when the working force is required to change steadily, or the working force is basically constant and the initial force is large, it is more important to determine the pressurization ratio.

(4), the choice of the special-shaped spring trip: no matter what kind of process, choosing special-shaped spring, we are always willing to total height of special-shaped spring don't is too high, lest produce unstable phenomenon and installed on the mould structure is too complex, and the trip, the greater the special-shaped spring is higher, the price of this independent type special-shaped spring is particularly important. If the process needs, the stroke is really large, it is recommended to use the special-shaped spring plate system, so as to reduce the height of the mold, improve the stability and reliability of special-shaped spring. Sometimes for safety, to avoid accidents, in the selection of shaped spring, need to increase 3-5mm safe travel.
