Application products of variable force spring: Variable force springs and variable torsion springs can expand negative gradients and positive gradients to form a single spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are no longer proportionally increased, but accompanied by various elastic force-displacement combinations, such as negative slope. Therefore, a stepped constant force can be achieved. Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications. What products can the curve changes of variable force springs be used for? Pen Type Drug Syringe Application The spring exerts a constant force to keep the drug flow in place, preventing patient discomfort during use. It has a stretch at the end of the stroke to ensure that all of the medication can be fully injected. up and down sliding door When the door is closed, the spring force is less than the door...

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...

Design of constant force springs: A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant. By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed. Design of Constant Force Springs: A constant force spring is a coil of prestressed...

Традиционные силовые пружины и пружины с предварительным натягом: Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs. During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design,...

Преимущества беспроводных пружинных компонентов Qianye: All curtain cords, whether installed on the side, caught in curtains, or placed on the back, can be dangerous to children. It is best to replace all corded curtains with cordless curtains in houses where children live or visit, especially in children's bedrooms and play areas. Cordless roller blinds with either a spring system or an electric system can improve the safety of the home. Cordless roller blinds with spring system are similar to movie curtains. They use the elasticity of the springs. Under the action of the spring components, the roller blinds can be balanced at any position and can be stopped at any time. At present, most of the spring components on the market are wire spring cordless curtain systems, which have a relatively short service life and a high degree of force attenuation. When pulling down, the curtain stops at each clip, and when rising, pulling down makes the curtain bounce...

Constant force springs applied in wall mounted accessories: As more and more people spend more and more time using computers, computer users spend more time sitting or standing at their desks or workstations in front of devices. Keeping what experts call "the best ergonomic positioning" can improve energy levels and overall comfort. For this purpose, the input and output devices must be placed in appropriate positions. The proper position can reduce the muscle strain of the user's arm and effectively prevent various musculoskeletal diseases, including carpal tunnel syndrome, neck pain, and upper and lower back pain. The attachment bracket can be used to facilitate the support and position adjustment of the fixed attachment. The attachment retainer allows simple three-dimensional adjustment of two such devices to place the devices in a more ergonomic relative position to meet the needs of various users and workspaces, and has a balancing mechanism for balancing the weight of fixed attachments. The balance mechanism provided by the wall mounted accessories is superior to the traditional lifting system,...

Constant force spring is used in removing an implanted object using laser cut hypotubes: Removal or extraction of the lead may be difficult. As mentioned above, the body's natural healing process forms scar tissue over and along the lead, and possibly at its tip, thereby encasing at least a portion of the lead and fastening it even more securely in the patient's body. In addition, the lead and/or tissue may become attached to the vasculature wall. Both results may, therefore, increase the difficulty of removing the leads from the patient's vasculature. A device for removing an implanted object from a body vessel, may comprise a sheath assembly comprising an outer sheath assembly and an inner sheath assembly, and a pin, the outer sheath assembly comprising an outer sheath and an outer band, the outer band coupled to the pin, the inner sheath assembly comprising an inner sheath and a tip, wherein the tip has a cutting surface, the inner sheath comprising a proximal end and a distal end, wherein the distal end of the...

Advantages of Qianye carbon brush spring in motor: There are many kinds of carbon brush springs. Wired carbon brush springs also have steel belt carbon brush springs. The linear type is mainly compression spring and torsion spring. These springs are traditional springs. At present, the more famous motor manufacturers or electrical appliance manufacturers have begun to use steel belt carbon brush coil spring in the motor. The traditional compression spring and torsion spring are relatively backward and are generally used in low-cost carbon brush devices. The only advantage is that the price is cheap, which is several times lower than that of steel strip spring. However, the use of traditional spring in medium and high-end motors greatly reduces the product quality and competitiveness. Compared with the motor using traditional spring, the coil spring motor is completely two different concepts and quality, and the sound produced by the operation of the two motors is also different, making the service life even more incomparable. The use of carbon brush spring greatly improves the service life and stability of the motor. The traditional type of spring is not only noisy but also environmentally friendly. However, there are few domestic manufacturers that can really do a good job in carbon brush spring. Carbon brush spring needs a long time of production experience to produce high-quality carbon brush spring. Shenzhen Qianye Precision Metal Co., Ltd. has more than ten years of product R & D, production and manufacturing experience, and various application designs and solutions of spring. The advantages of carbon brush spring produced by Qianye in motor application are as follows: 1 Shorten the outer diameter of the motor...

Depending on the requirements of your specific design, it may be beneficial to use a fixed mandrel/free box or free box/fixed mandrel arrangement. These springs are typically used to retract the cord or cable of the spool. You might see it in lawn mowers, retractable lanyards, or dog leashes. This is also the type of spring used to drive many mechanical clocks and timers, which is why they are sometimes called "clock springs". The load provided by the spring increases with the cross-sectional area of the material. The number of turns the spring can provide depends on the space available between the mandrel and the...

Application of constant force spring in lifting window: The lifting window is different from the traditional internal opening, external opening and ordinary push-pull mode, but adopts the opening mode of lifting up and down. Because it is mainly popular in North America, it is also called American lifting window. It is one of the two major door and window categories in the world. The lifting window is more compact than the left and right lifting windows, which is determined by the structure of the window. The traditional lifting window is a sash frame structure, that is, when the window sash is opened left and right, it is realized by sliding the lower pulley on the sliding rail of the window frame. However, there is a gap between the pulley and the slide rail, and the smoothness of the opening must be taken into account, which will inevitably lead to the decline of the sealing performance. The lifting window is a frame-encased sash structure. The sash is wrapped in the window frame and runs vertically up and down. Through the multiple seals of high-quality siliconized tops, the sash frame is tightly fitted around it, and the sealing performance is significantly better than that of the left and right lifting windows, second only to Fixed and casement windows. The advantages of the sliding doors and windows are: 1. The characteristics of large ventilation, the lifting windows can be opened by 2/1, and the air entering the room can be convected. The European-style lifting windows and casement windows basically cannot open more than half of the area. Second, there can be different...

Do you know about the constant force spring module?: I'm sure many of you know what a constant force spring is, right? A constant force spring is a spring that maintains a constant spring force for a specific stroke, also called a constant force spring, and is used in a linear motion, usually using its rebound force. A constant force spring consists of a spiral-shaped metal sheet that is bent on the inside so that each coil is wound tightly around the innermost coil of the metal sheet. When the metal sheet is stretched, the internal stress resists the load force, which is exactly the same as a normal extension spring, but the spring force is very constant and can output a nearly linear spring force. The use of a constant force spring on the lift support enables the supported structure to hover over gravity at any position during the allowable travel. However, in order to achieve a variety of functions and operations, the supported structure, such as a monitor, usually weighs more than the white body of the device. In order to ensure a large support force, the constant force spring needs to use a thick elastic metal sheet. However, the thick elastic metal sheet will lead to a short effective constant force spring travel. The purpose of this constant force spring die set is to provide a constant force spring die set that is capable of maintaining a large constant force lift value and a constant force effective stroke within an effective mounting space. Another purpose is to provide a constant force spring lift mechanism that not only provides a greater constant lift force, but also reduces the mounting space of...

Application of variable force spring in electric roller shutter: The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...

Применение пружины постоянного крутящего момента в 3D-принтере: 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...

This is due not only to their professional manufacturing technology, but also to the reduced costs associated with transporting and handling parts. You can also avoid indirect costs of labor, manufacturing equipment and raw...

Do you know how clockwork toys work?: Clockwork toys use constant torsion springs made of stainless steel coils. An external force rewinds the spring to the output wheel (energy storage) from its natural state. When the force is removed, the spring returns to its natural state. At the same time, a constant torque (stored elasticity) is generated (released) at the output wheel, hence the term constant torque spring. The torque is greatest when the barrel is fully wound so that the front end of the barrel needs to be output with less force. After a certain period of time, the winder, which is tightly coiled on the winding shaft, will slowly unwind and its energy will drop. When the energy is about to be exhausted, the torque at the end of the barrel is at its minimum and the force output is then reduced. Thus, the driving force needs to be increased to keep the movement running. This is why constant torque springs are so suitable for wind-up toys. We have 20+ years of experience in spring design, development and production. Contact us to find the best solution for your product to meet your application requirements.
