Design cordless curtain springs
Design cordless curtain springs
There are many types of curtains on the market today, such as Venetian blinds, Roman blinds and honeycomb blinds. When the curtains are lowered, the windows can be shaded to reduce light entering the house and improve privacy. Generally speaking, curtains are provided with control ropes, which can drive the bottom rail of the curtain to rise or fall. In particular, the bottom rail is raised by a roller take-up hanger, and the hanger can be extended from the roller so that the bottom rail can be lowered.        However, the problem that the control cord may restrain children has been noted, so a cordless curtain has been developed. This cordless curtain can raise and lower the bottom rail by means of a coil spring box.

Ressort à force variable dans un dispositif d'administration de médicaments
Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles. Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles. Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed)....

 How to determine the length of a constant force spring
How to determine the length of a constant force spring

Heure:2022-9-14

  Constant force springs are mechanical devices used in applications that typically require some kind of balance or retraction mechanism. In design and function, constant force springs differ from the more common types of coil springs. They apply a consistent linear force or torque that remains constant over a wide range of motion. When a coil spring is under force, whether it is stretched, compressed, or rotated, it produces a force proportional to its stretch. How a spring responds when a force is applied or released is called spring deflection. Years of experience tell us what happens when a spring is released from its temporary state. We know that the spring will return to its original position, but it will be proportional to the force exerted on it before releasing. A spring has a restoring force that allows the elastic material to return to its original state - the equilibrium position after the applied force is removed. Stretching, squeezing or twisting, what makes a coil spring a spring is its proportional restoring force. It's named after the 17th-century British physicist Robert Hooke who made the discovery, according to Hooke's Law. Essentially, this law describes a linear relationship where the amount of stress applied to a spring is proportional to the force applied to it.     Determine the length of the constant force spring Constant force springs differ from traditional helical wound springs. First, they are made from high-volume, thin pre-stretched stainless steel strips that are coiled into flat spirals. In contrast, coil springs are not flat, thin steel strips, but are...

Tape measure, I believe everyone is familiar with it. Tape measure is a common measuring tool in our daily life and work. After the tape measure is pulled out, it can be rolled up because there is a power spring in the tape measure. When pulling out to measure the length, it actually lengthens the length of the scale and spring. Once the measurement is completed, the spring in the tape measure will automatically shrink, and the tape will also shrink under the action of spring force, so the tape measure will roll up. The power spring is an elastic fitting in the tape measure. The end of the steel bar scale is connected to the front end of the spring, and the end of the spring is fixed in the middle of the tape measure. The tape measure mainly uses the energy storage characteristics of the spring, which can be said to be the conservation of mechanical energy .When you pull the tape measure, you work on the internal spring, and the energy is stored by the power spring; when you release it, the spring relaxes, releasing energy and causing the tape measure to retract automatic contraction uses the lever torque principle: in the stretching state, the force arm is the smallest and the spring output is the largest; in the retracted state, the force arm is the largest and the spring output is the smallest.         When the scale is pulled out, the spring is tightened to produce a force to roll back. When the tension of the scale is released,...

Qu'est-ce que la passivation ? Mon produit en a-t-il besoin ?

Heure:2022-9-14

 "My new stainless steel product specification requires' passivation '. Do I need it?" Our answer is that you may not. That's why. Passivation is the process of protecting stainless steel from corrosion by adding an oxide layer on its outer surface. Although some stainless steel product specifications require passivation to reduce corrosion risk, most of them are unnecessary and expensive, and may damage some metal products, including flat bar springs, such as constant force, variable force and constant torque springs, all of which are uncommon products manufactured by Qianye precision.     The reason passivation is not a good idea for flat bar springs is because passivation involves the use of acids and harsh chemicals to initially clean the metal as part of the process. The geometry of these spring types means that many small cracks can form between the coil layers. The acid used in passivation can become trapped in these crevices. This resulted in longer-than-expected exposure of the stainless steel, which in turn resulted in hydrogen embrittlement and eventual spring failure. Additionally, mechanically exposing all surfaces of the spring to acid can damage the spring, resulting in changes in force/torque output or defects. There are better, simpler, cheaper ways to avoid any need for corrosion and passivation of stainless steel components, and it's as simple as choosing a fussy material. Remember that the risk of corrosion of any stainless steel component is driven by the environment (such as the presence of water and other chemicals) and Qianye Precision typically uses high quality 301 stainless steel for our springs....
