트윈 스프링 또는 모터 브러시 스프링의 설계 및 기능
 One of the most unique spring designs is called a twin spring.  Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material.  These custom springs are intended to work together, in unison, doubling the force of a single spring.  Twin springs are a version of a constant force spring, providing constant force throughout the travel length.     The area between the two coils is referred to as the saddle area, which is formed to fit over the part or component that is being pushed.  The saddle can also be cut-out to provide access to the component and is best designed when assigned a dimension to fit over that specific part.  It can be located at different heights between the coils for ease of assembly or as an indicator for direction.     Twin springs are used in a wide range of applications where available space is limited and a relatively strong...
Small spring has great effect
Small spring has great effect
The reason why the world we live in is so orderly is that there are precise links between large and small objects. So many things in life are crucial. Whether they are large or small, they are indispensable to our life, but some small parts in life are unknown, but there are tens of thousands of them. The spring I know is also one of them. It always exists in a position that people can't see and does their own thing silently. Moreover, he exists everywhere in life, even if we don't know it. Today, I will explain the functions of these small springs. Spring is a kind of mechanical part that uses elasticity to work. Generally made of spring steel. Although the spring is small, as a general basic part, it has large quantity, wide range and complex varieties. It is used to control the movement of mechanical parts, mitigate impact or vibration, store energy, measure the size of...

[Qianye Precision]Advantages of constant force spring
 The unique quality of constant force spring makes it a perfect balance for heavy moving parts. If your equipment requires springs, consider constant force springs. This is a kind of tension spring. They do not obey Hooke's law, so their force remains unchanged, even when deflected. Constant force spring can be used in almost all kinds of products. Some of the largest consumers are medical device manufacturers. Machines, dental X-ray equipment - and almost any articulated and heavy equipment - are equipped with constant force springs. Smaller constant force springs for medical devices are also part of syringes and drug injectors. We can also find a large number of constant force springs in daily necessities, such as retractable key chain, retractable dog rope, vacuum cleaner, thread winder, safety belt, window balance system, indoor shutter and monitor lifting and so on. Due to the flat force curve of constant force spring, constant force spring is suitable for applications requiring stable motion range and constant load. To...
Design and manufacturing method of constant force spring
Design and manufacturing method of constant force spring
 Design and manufacture a complete set of constant force springs for a variety of applications in almost all industries, from medical care to aerospace and general household products. The constant force spring is different from the traditional spiral wound spring. They are made of pre tensioned high-yield metal strips (usually stainless steel) rather than wires. Constant force springs are classified as "tension springs". When winding, the metal strip resists uncoiling with nearly constant resistance. When extended, the internal stress of the metal resists any load force at a nearly constant rate. Once the spring extends to a length of 1.25 times its diameter, it reaches full load and produces a nearly constant force. According to the size of the spring and the load it supports, the fatigue life cycle of the constant force spring is between 2500 and 1000000 times.     Constant force springs are commonly used in automotive engineering, aerospace engineering, medical and retail. Some common applications are:...
3 types of springs and some common applications
3 types of springs and some common applications
Smooth Range of Motion: Constant Force Springs Constant force springs provide a smooth range of motion and constant load, meaning they do not follow Hooke’s law. They are uniform in length and coiled into a permanent diameter. Constant force springs are frequently used for applications that require counterbalancing, including windows. In fact, window balance springs are one of our most successful products. In addition, the springs we manufacture are often designed for medical devices and aerospace applications. Their smooth range and steady motion control enhance instrument articulation.   High Torque with Little Rotation: Spiral Torsion Springs Spiral torsion springs are another popular product we manufacture.These springs are ideal for applications that require high torque and less than 360 degrees of rotation. (270 degrees maximum is preferred). Spiral torsion springs are commonly used in applications that require a “return to center” function, like a medical instrument joystick. They’re also ideal for electric motors and automotive applications. If your application requires this “return to center” function, developing a...
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. Coil spring boxes used in window blinds usually consist of multiple springs that provide torsion to maintain the bottom rail at the desired height. However, the assembly of such a coil spring...

Mention of diabetes, I think everyone is not strange. Data show that by the end of 2021, the total number of type 2 diabetes in China was about 120 million. When oral hypoglycemic agents are standardized and blood glucose control is still unsatisfactory, insulin injection is an inevitable choice for the treatment of type 2 diabetes. Many may not know that insulin injections require dedicated syringes. Some kids are worried. Does injection take technical issues into account ? Actually don 't worry at all, because what, because the use of the Qianye  power spring ! Qianye power spring can provide small and highly accurate drug dose. The quantitative drug is injected into the body through the spring fixed force, thrust and homing speed. The thrust distribution of the steel strip spring accurately matches the sliding force of the traditional syringe. It solves the problem of emission tolerance of the syringe and provides a high thrust demand for highly viscous solution.     The device of insulin injection pen consists of handle, needle cap body, trigger device, insulin needle, needle hole and dynamic spring. The trigger device is started by the button to make the spring inside the needle cap contract instantaneously, and the spring elasticity drives the needle to penetrate into the subcutaneous tissue at a certain depth instantly, so as to effectively relieve the fear and pain of the patients, reduce the trauma area, improve the treatment compliance, enable the patients to carry out effective site rotation injection, and improve the treatment effect.  The reason why insulin injection needs special syringes...
 Constant Torque Spring Motor
Constant Torque Spring Motor

시간:2022-9-14

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...
 Custom springs for medical devices
Custom springs for medical devices

시간:2022-9-14

For most of the past two decades, the medical device industry has been booming. Healthcare research has led to the rapid expansion of specific devices used to treat medical needs, from rare to common. These devices range from simple to surprisingly complex, often including automatic sensors, computer monitoring, and even remote monitoring by healthcare providers. When you are designing for a new medical device, it is essential to consider the components you must put together and the system they will create. This means breaking down your design to a level where you can visualize the components that need to go into the project. This means designing each spring assembly individually after evaluating the available options. To help you solve this problem, here are the four most commonly used springs for medical devices and their current common applications.    Constant force springs Constant force springs provide a smooth range of motion and a constant load in either extending or retracting direction. This spring design has no inertia to overcome when considering the initial position forces. Constant force springs are compact and mount easily to existing hardware. These types of springs can eliminate the need for costly and complicated motors, thus decreasing device size and cost.   Spiral torsion springs Spiral torsion springs are normally used in applications requiring less than 360 degrees of rotation. They are generally used to obtain a large amount of torque through a small amount of rotation. Spiral torsion springs allow for rotation in two directions and a “return to center” capability, like a dental X-ray head unit.   Spring reels Spring powered...
 Application of constant force spring in refrigerator door
Application of constant force spring in refrigerator door

시간:2022-9-14

In order to make the refrigerator operate effectively, the door should be kept closed. Keep the door open for a short time when putting or taking out food. However, opening it for a long time will affect its cooling and endanger food safety. It will also lead to excess power consumption. Fortunately, the modern refrigerator door can be added with a constant force spring to automatically close after you open the refrigerator for use. Nowadays, this kind of design is relatively rare in the market. It is generally a magnetic refrigerator door, which explains why the magnet is attached to it.   We have seen that it is essential to keep the refrigerator door closed all the time. If the door remains open for a long time, it will counteract the internal temperature balance and affect the quality of the food stored in it.When this situation continues for a long time, the compressor cannot maintain a low internal temperature. This undermines its operational efficiency. In addition, the longer the door is opened, the hotter the inside of the refrigerator will become.   Because it is very important to keep the door closed, a constant force spring is added to the refrigerator door. If you open them, they will close automatically.A constant force spring is added, which pulls the door back and seals it tightly to the frame when the door is opened. Constant force springs are often the best spring type for this application and can be manipulated in a number of ways to ensure your design works. Constant force springs are characterized by a...

Pull Bead Roller Blinds and Cordless Roller Blinds

시간:2022-9-14

The roller blinds are blackout roller blinds, soft yarn roller blinds, and Shangri-La roller blinds in appearance. They are mainly corded and cordless. Roller shutters have many advantages such as beautiful and simple appearance, firm and durable structure, etc. Roller shutters are suitable for various places, especially for large-area glass curtain walls. When the roller blind fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good shading effect. When the roller blind is raised, its volume is very small, so that it is not easy to be detected.        The bead roller blinds use the rope or chain to ascend and descend. The biggest problem of the rope/bead system is that the curtain will not be pulled when it is too big, and the rope will easily break. It is not very convenient to use, and the rope is easy to get dirty. It is very dangerous for children to play with ropes. In developed western countries, the use of beaded roller blinds has been banned and cordless curtains are fully used.        There are many complex components in the spring mechanism control part of many cordless roller blinds on the market, such as: deceleration device, damping device, gear device, limit device, etc. Qianye cancels the traditional complex components, and uses professional spring technology to design, it becomes A spring assembly that can stop at will.        Cordless roller blinds can balance the roller blinds at any position under the action of the spring...

As everyone who knows our company knows, our company also has another product, that is, dog walker! The power spring is the core and main component of the dog walker. The power spring is made of 301 stainless steel with high precision and high hardness. Its thickness tolerance is controlled in the range of 0.01mm and its hardness is hv580 degrees. The service life of the dog walker can be extended to 30000 to 100000 times. When this power spring is applied to the dog walker, the quality of the dog walker has been greatly improved. When walking the dog, we need to pay attention to bring the dog's little partner - the dog walker, and then the obedient dog should also bring the dog walker. Don't expect the bridge section of the dog looking for the master in the movie to happen. Before using this kind of traction rope, I always used a fixed 1.5m long rope. Usually I use the traction rope to prevent dogs from running around and attacking pedestrians. But there was once a time when walking a dog. Now many shared bicycles and electric vehicles often shuttle back and forth at a fast speed when walking around the corner. An electric motorcycle brushed past the dog. Fortunately, after the rope was shortened, it was able to effectively protect the dog and prevent accidents. However, many friends would say that it would be good to buy a shorter rope? But in fact, many times we need to give dogs enough range of activities, so this time can reflect...

As the times change, gas stations are gradually replaced by electric vehicle charging stations. We have always been a natural partner for designers and manufacturers of electric vehicle charging stations, because they need to be compact, clean and provide trouble free cable management solutions for their electric vehicle charging stations around the world.   By applying our power spring to the retractable cable drum, the cable wear is reduced, the tangled cable is eliminated, and the cable can be neatly stored when not in use. In this way, we help EV charging station developers shape the future of safe and trouble free charging of electric vehicles. The natural expansion trend of the power spring gives a torque to the spindle or case, resulting in a usable torque. The generated torque is cumulative, so the torque will increase as the spring is tightened and decrease as the spring is loosened. Torque and total number of turns are the most important output requirements in the design of power spring.
