spring leaf effect is making the application of 1, the diameter of the effect is.
General volume spring can ensure diameter deviation, but when play than yellow wrapping too kong level play yellow diameter standard tolerance is a tall order,
Beyond the yellow standard requirements)
, the diameter must be effect is.
Effect is that can be a common forceps, pin and shaft neck, etc.
2, section size and the height of the effect is.
When pitch as important indicators of project completion acceptance and yellow height cannot guarantee under the condition of casually, can use of the way is to adjust.
3, smoothness effect is.
For beyond the requirement of high precision flatness, during drilling and there is no guarantee that the case, can according to the effect is to enhance the precision of the flatness.
two
Battery spring piece effect are the advantages and disadvantages of spring manufacturers effect is producing technology is the tool of basis must make play yellow lead to part of the plastic deformation and go beyond the requirements of the sample on the drawing.
Effect is a multifaceted: not only promoted specifications precision, in addition to adverse impact on the characteristics of the spring, so that the hazard.
To reduce the effect is the damage, the characteristics of the elastic yellow effect should be to deal with the stress annealing after is.
3.
Reduce the battery spring pieces of the method is effect is high Labour productivity, time consuming, improved the production and processing cost directly.
Thus from the following several aspects to take measures to reduce or cancel the effect is the production process.
1, under the necessary condition to maintain yellow important feature, when the scheme design of flatness, pitch diameter precision indicators such as far as possible don't explicitly pointed out that high requirements.
2, improve spring precision grinding.
Make play yellow smoothness considering the requirements of the drawings as far as possible.
3, play yellow uniformity of physical properties and creditability, especially playing the yellow material tensile strength level should be small fluctuations.
4, improve precision coil spring.
Make play yellow on both sides of the circle circle of spiral Angle, and even the same section, uniform size, same height error control within the range must be casually.
