Variable force spring in drug delivery device: 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)....

Vzmetni motor s konstantnim navorom: A constant torque spring motor is a strip of prestressed spring material that forms a coil and is stored on a small storage drum. The free end is then pinned and rewound onto the larger output drum; this is the "winding" part of the constant torque spring cycle. When the output drum is released, the spring will return to the storage drum to assume its natural curvature, rotating the output drum and providing an almost constant torque. Constant torque springs are made of type 301 high quality stainless steel and are supplied in coil form for mounting on the motor drum. Its main features are: 1. Long time deflection under almost constant torque. Positive or limited negative gradients can be achieved. 2. Minimal inter-coil friction and resulting hysteresis, which is common in power springs. 3. Rotary motion is provided directly from the output drum or linear displacement by using cables and spools. Many applications utilize constant torque spring motors, such as: cord retractors, balance retrieval and return applications, drive motors, cordless curtains, and more. The spring features a high turn design, making it ideal for balancing applications. When they are fully turned, the springs apply a constant torque. You can also guarantee high torque levels. This is due to their compactness and high efficiency. The function of the constant torque spring motor depends on the design. The size of the spring can vary. Therefore, they make them suitable for use in a variety of applications. We strongly recommend that you consult...

What is passivation? Does my product need it?: "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....

Congratulations on the return of Shenzhou 13 spacecraft: At about 10 am on the 16th, the "Shenzhou 13" manned spacecraft landed smoothly, and the three astronauts who had been on a business trip for half a year also returned safely, and the hearts of many people also fell to the ground. At the same time, Yang Liwei's voice that appeared in the live broadcast room also made many people's soul wear 2003. Recalling that when the "Shenzhou V" was successfully launched in 2003, the first batch of post-90s generation was just thirteen years old. "Shenzhou No. 5" may already be a term with a sense of age for the late-born children of Generation Z and Generation Alpha. Mankind's curiosity and desire to conquer space have never stopped. What does the vast universe look like with human naked eyes? Is it really romantic and exciting to be in space as outlined in science fiction films? Is space really desolate and silent? Because outer space is full of all kinds of mysteries, human beings may be afraid to see the deep universe in outer space, especially when they float in outer space when they get out of the cabin. Therefore, when the astronauts leave the cabin, they are tied to the astronauts with an 18 meter long rope and connected with an oxygen pipe to provide life support for the astronauts. If the astronauts do not grasp and drift, they can use this rope to return to the space station. Fortunately, our Qianye precision has also made a small contribution to the national aerospace industry. We are mainly involved in...

Add constant force spring in the mechanical arm to make it more stable: Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc. The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced. The pivot is a connecting ring that can rotate around an axis set at the pivot point, and a way to attach a spring to the pivot point to reduce the amount of force required. Apply to the arm to place the supported object in the desired position. The auxiliary balance device uses a constant force spring, because the constant force spring provides a smooth range of motion and a constant load in the extension or retraction direction. This can provide smooth motion and force requirements that predict the smallest detail, and the force applied by the constant force spring is more constant over the entire range of motion of the two arms of the device. If coil spring balance is used, a constant force may not be applied to the supported object at all positions of the upper arm part and the lower arm part. For example, at the far end of the range of motion, usually, the force applied to the supported object is insufficient or too large, making it difficult and troublesome to place the...

Konstrukcijske stopnje vzmeti s konstantnim navorom: Constant torque spring is a constant force spring with special force moving between two spools. The spring is stored on the storage spool and wound reversely on the output spool. When released, torque is obtained from the output spool when the spring returns to its natural curvature on the storage spool. The spring does not need to be connected to the storage spool. The spring can be installed in a cavity without storing the spool at all. However, friction will then be introduced and torque requirements will change. The torque generated by the constant torque spring will increase slightly after several revolutions. Constant torque, even negative torque, is also possible. Negative gradients of up to 50% can be achieved in some applications. As for the design of constant torque spring, when considering the use of constant torque spring, it is strongly recommended that you talk with Qianye engineers and study various design parameters. Some initial design calculations can be carried out according to the following eight steps. 1. Select materials Most of the springs we produce are made of type 301 stainless steel. This material is readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. We also use high carbon steel, Inconel and Elgiloy in various designs as needed. 2. Life expectancy This is one of the most important considerations because the life of constant torque springs is very predictable. Practical is important because it is estimated that high life cycle requirements may lead to larger and more expensive designs. Of...

Power spring used in automobile safety belt: Safety belt is equal to life belt. Everyone should see the painful accidents caused by not wearing safety belt. I believe everyone is familiar with the car safety belt. It is a safety device to avoid rushing out of the car during collision and causing death and injury. Automobile safety belt is recognized as the cheapest and most effective safety device, and it is also a necessary safety configuration. In a typical safety belt system, the safety belt is connected with a retractor. The core component of the retractor is the reel, which is connected with one end of the safety belt. Inside the retractor, with the help of the action of the power spring, the webbing can expand and contract freely with the movement of the user's body without loosening the webbing. In case of emergency braking, collision or sharp change of vehicle driving state, the sensitive element in the retractor will lock the reel to fix the webbing at a certain position and bear the load imposed on the webbing by the user's body. The power spring is made of rolled steel strip. A spring box is required to limit its outer diameter in use. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store torque. When the external force disappears, the spring will produce torque on the shaft or spring box. Qianye has made technical product updates for power springs. First of all, our company...

Physical principle behind constant force spring: When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are widely used in daily applications. From door closers to rope and hose retractors, to sports equipment, toys, motors, etc., constant force springs exert force at an amazing high frequency and consistency. Let's take a closer look at the basic physics behind the constant force spring. In the 17th century, the British physicist Robert Hooke proposed a formula for force and elasticity, which is now called Hooke's law. Hooke's law states that the force (f) required to stretch or compress a spring for a distance (x) varies linearly in proportion to that distance. The formula is f=kx, where k is a constant and represents the stiffness of the spring. Constant force springs in terms of actual spring performance, Hooke's law is nominal. In the equation, the distance X that the spring moves is a relatively small number. Finally, any elastomer that is stretched or compressed beyond the stress limit of its material composition will show signs of deformation. Therefore, the force properties that depend on the consistent shape and tension state will change in the deformation state. Ideally,constant force springs will exert a consistent force over a given range of motion, repeating without changing. In fact, constant force springs, like all elastomers, are limited...
