Ta yaya kuke oda Kananan Maɓuɓɓugan ruwa tare da ƙugiya?
Your small spring needs custom hooks, but the standard options break. Now your project is stalled, duk saboda kankanin, amma mai mahimmanci, connection point that keeps failing.
To custom order a small spring with hooks, you must specify three key things: nau'in ƙugiya (E.g., mashin ƙugiya, crossover madauki), ta fuskantar (kwana tsakanin ƙugiya), and the hook opening size. These details are as crucial as the spring's coil dimensions.
I've seen it happen many times in my career. An engineer will spend weeks perfecting the force and size of the spring's body, only to treat the hooks as an afterthought. But in an extension spring, ƙugiya kusan koyaushe shine ma'anar mafi girman damuwa. Jikin bazara za a iya tsara shi daidai, amma idan ƙugiya ne mai rauni mahada, gaba daya bangaren ya kasa. Let's break down exactly what you need to specify to get hooks that are strong, abin dogara, kuma ya dace da ƙaramin aikace-aikacen ku.
What's the Most Common Mistake When Specifying Hooks?

How Does the Hook Design Affect the Spring's Strength?
Kuna buƙatar maɓuɓɓugar ruwa wanda ke ja tare da takamaiman ƙarfi, amma ƙugiya na al'ada da alama suna canza aikin sa. The spring feels weaker than your calculations predicted it would.
The length and style of the hooks directly impact the spring's initial tension and active coils. Longer hooks or hooks with extended loops add "dead" coils that don't contribute to the force, which can slightly reduce the spring rate and overall stiffness.
This is a subtle but important point that can confuse designers. I had a project for an electronics company where the spring had to fit into a very tight space and deliver a precise force. The engineer's calculations were based only on the spring's body. But their design required very long, extended hooks to reach the connection points. When we made the first samples, the force was about 10% lower than they expected. We had to adjust the coil body, making it slightly stronger, don ramawa ga "marasa aiki" waya a cikin dogayen ƙugiya.
