Use spring from time to tome what considerations?

by:Yongqiang     2020-11-09
A small spring beside people close at hand, when people never care about it, it appears in refill ink, in daily life is spring around in the home, shower gel, detergent, weak perfume, all you can see can knead knead with nozzle of appliance, full of a spring, a small spring has
a pretty big effect, silently trying in this item, and is currently on the market on the improvement of the spring there is a rectangular box spiral spring, improving its service performance. So that customers can safely application, helpful hints of common problems and should prevent spring manufacturer operation method: (1) no spring guide application in no spring guide under the standard of application, the spring will produce buckling and transverse bending condition, bend in the side of the part will cause the high in-situ stress, lead to wreck after *. Therefore, please try to application guide shaft, such as diameter of guide spring guide. Does in general, according to the nominal diameter side guide will guide shaft top-down application more ideal after all. (2) about the spring if nominal diameter and guide shaft and guide shaft in the middle of the space is lesser, guide shaft makes the spring nominal diameter is caused damage, and damage to the department as starting point, after * lead to wreck. In addition, if and guide shaft in the middle of the gap is too big, will lead to buckling. Proposed guide shaft diameter smaller than nominal diameter 1. 0 mm up and down. In addition, the random length longer spring ( Arbitrary length/diameter is about 4 spring) The guide shaft to include touch when ups and downs in case of transverse bending spring nominal diameter. (3) related to the diameter of the spring and sink a hole if and sink hole in the middle of the gap is small, will be caused by after spring to reduce the diameter of a side frame up diameter by binding, produce stress, * causes the wreck. Proposed a sink hole diameter is larger than diameter of 1. 5 mm up and down. Arbitrary length longer sink hole like in the spring to choose relatively ideal. (4) guide shaft length, deep sink hole more hours if the length of the guide is lesser, spring buckling when touch guide front development, causing friction, lead to wreck after *. Proposed to guide the length set to the original Settings ratio by about half. In addition, to carry out about C3 fillet. (5) beyond the large tensile variables ( 300000 times) The application of ( When close to the clamping length around the application) Application frequency of more than 300000 times or so, the cross section causes beyond measure the value of high ground stress, * causes the wreck. In addition, because of the clamping length, reasonable spring, slowly pour machine part of tight, spring constant expansion, the load curve to rise, so will cause the high in-situ stress, * causes the wreck. Thus, application frequency need not more than 300000 times. Those without the original application under tensile strain criteria if have space, spring is the fitness movement up and down, and produce buckling and transverse bending. If the application again after removing the original tensile strain, spring on the bottom will be more and more smoothly. 7 hold waste, dirty case application if hold dirt, so you lose efficacy reasonable relative part of spring rolls and result in addition part of tensile strain, which in fact is equal to the reduced the reasonable spring number of turns, so will result in high ground stress, * causes the wreck. Therefore, warm reminded not to make waste, into the dirt. Mounting surface flatness of the end application of weak ground if installation surface flatness is weak, shenzhen spring can cause transverse bending, bending in the side of the part will cause the high ground stress, lead to wreck after *. In addition, the flatness of abrasive weak, also can because spring bending, as well as application of around 300000 times sake * causes the wreck. So please improve the installation surface flatness, and there is no need to more than 300000 the number of application standards.
