 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...

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...

What do you think of the correct sitting posture in office? Relax your shoulders, keep your eyes in front, and keep your eyes balanced at the top of the computer or the top 3 / 1 of the monitor. This is the correct sitting posture of our office. To stand our neck, we need a certain height of the display. The horizontal position of the display is low, and the neck is easy to tilt forward. The cervical spine will obviously feel uncomfortable, very tired, and will cause pressure on the muscles of the neck.      The display bracket is mainly composed of upper support arm, lower support arm, display connector and desktop clamp. The most important core lifting components are in the upper support arm, which supports the display through the deformation of spring or air rod structure in the upper arm. When it comes to the spring in the core lifting part, the reason why the display can rise and fall is that it is designed into a lifter that can adjust the height of the display at will by using the principle of free rise and fall of constant force spring. With the help of the tension of the spring, its height can be adjusted freely. Compared with the column support (the lifting up and down is cumbersome, and the screws need to be adjusted by tools every time) it is simpler to use and more convenient to operate after adding a spring. It only needs a little effort to complete the adjustment, which can be said...

 Nine factors that should be paid attention to in spring production
Nine factors that should be paid attention to in spring production

Tid: 2022-9-14

A spring is a mechanical part that works with elasticity. Generally made of spring steel. It is used to control the movement, buffering or vibration, energy storage, force measurement, etc. of mechanical parts, and is widely used in machines and instruments. (1) Elastic limit - the elastic limit is related to the tensile strength. Selecting a material with a high elastic limit is usually equivalent to selecting a material with a high tensile strength. (2) Spring coefficient - the stress applied to the spring material to produce a unit strain is called the elastic coefficient value, which mainly depends on its chemical composition.    (3) Fatigue strength - fatigue strength must be considered for springs subjected to dynamic loads.   There is a certain relationship between fatigue strength and tensile strength of materials. (4) Hardenability - in order to improve the quenching effect, the material is required to have good hardenability, and at least 50% of the central block iron structure shall be quenched. (5) Shape and size - the mechanical properties of the spring material change with the size. The manufacturing size of the spring material is allowed to have tolerances. Therefore, the material must be selected according to the accuracy of the spring load characteristics.(6) Heat resistance - some springs are used at certain high temperatures. Generally, the mechanical properties of spring materials decrease with the increase of temperature, and the spring performance decreases after a certain temperature.   (7) Corrosion resistance - when the spring is used in a corrosive environment, the corrosion resistance of the material mainly depends on its chemical composition.    There are many corrosion factors, so we...

 Application of constant torque spring in 3D printer
Application of constant torque spring in 3D printer

Tid: 2022-9-14

3D printing, also known as three-dimensional printing, is a kind of rapid prototyping technology. It uses adhesive materials such as powdered metal or plastic to construct zero objects through multi-layer printing layer by layer. Mold making, industrial design is used to build models, and is now developing into product manufacturing, forming "direct digital manufacturing". Some high-value applications (such as hips or teeth, or aircraft parts) already have printed parts. The constant torque spring is applied to the 3D printer. This innovative case is a spring motor drive system. Like the common design, it is impossible for a spring to achieve the torque we need. As you can see we are using three constant torque springs in one mechanism with an output drum in the middle connecting the three springs. Therefore, it can generate three times the output torque of only one spring, and this design can achieve the purpose of providing maximum torque in a limited space. This connection method is easier to assemble than using screw connections.        When it comes to spring design, design engineers must consider many factors. These factors include not only part function and mechanism design, but also detailed material selection, part connection installation method and size. It's all about manufacturability. Feasibility analysis is required to ensure the functionality meets the customer's needs.        From the initial design stage of the spring set to production and final assembly, Qianye can save customers product development time, find optimized solutions beyond your expectations, no manufacturability constraints in product design, and the best product...
 Application of power spring in aircraft luggage compartment
Application of power spring in aircraft luggage compartment

Tid: 2022-9-14

Luggage compartments in the aircraft cabin are usually located above the heads of seated passengers. To ensure optimum headroom between luggage compartments on the one hand, and to facilitate loading on the other hand, aircraft luggage racks can be lowered from shell luggage compartments or trays in certain applications. When lowered, the front of the luggage compartment opens for loading. A luggage compartment with a lowered housing for an aircraft, wherein the lowered housing is connected to a pulley attached to a support structure of the aircraft by a cable. In order to lower the shell, when the rope lifts the shell on the pulley, the rope is released from the pulley, in which the pulley is biased by the force of the power spring along the rotation direction of the rope wound on the pulley. The power assistance for the pivoting of the luggage cover is realized as a spring device. This solution can achieve low maintenance and wear-free equipment in every case.   The natural tendency to expand of the power spring imparts a moment to the arbor or case, resulting in usable torque. The torque produced is cumulative, so the torque increases as the spring is tightened and decreases as the spring is loosened. Power springs that can be assembled into the customer's housing for immediate assembly, or a retaining ring is provided for transferring the spring into the customer's housing. Power spring torque and total turns are the most important output requirements in power spring design. The performance of a power spring depends on the size of the spring material (thickness, width and length) and available space (housing and mandrel...

 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...
