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.

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...

Tradicionalne močne vzmeti in prednapete vzmeti: 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,...

Prednosti brezžičnih vzmetnih komponent 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.

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...

Zasnova in funkcija dvojne vzmeti ali vzmeti motorne krtače: 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 force is required. Medical devices and surgical mechanisms incorporate this design to push or feed surgical staples in disposable skin staplers. Electric motors utilize the twin spring to provide a constant force on the carbon brush, extending the life of the motor and increasing reliability and overall quality. These springs are also referred to as motor brush springs. Advantages of twin spring: 1. Under the same elasticity, the double winding spring saves volume. 2. Because the shape is symmetrical, the output is more stable. 3. Increase the length of available carbon brushes. ...

Predtoplotna obdelava vzmeti: Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life. What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store and measure the size of force. It is widely used in machines and instruments. For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring. In fact, the so-called pre heat treatment is what we often call annealing. It is to heat the steel to a certain temperature and keep it warm for a period of time, and then cool it slowly. Annealing of steel is a heat treatment method in which the steel is heated to the degree of phase transformation or partial phase transformation, and then cooled slowly after heat preservation. The purpose is to eliminate the structural defects of the spring, improve the structure, homogenize the composition and refine the grain, improve the mechanical properties of the steel and reduce the residual stress; At the same time, it can also reduce the hardness,...

Exposed Power Cord Solutions: As people are becoming more and more picky about the beauty of home appliances, the problems of dirt, vulnerability and difficult placement caused by the exposure of power lines have been unsatisfactory. However, with the take-up device, the wires are completely stored in the internal space after use, and these problems are solved. Its core component is the use of winding up. Take-up spring refers to a kind of rotary spring that puts the steel strip crimped once or twice into the fixed box, and then connects it through the middle mandrel to tighten it to the predetermined position. After releasing the preload when necessary, it uses the rebound force of the rolled steel strip to achieve the design purpose. The utility model has the advantages that the utility model is designed for rotary use, and can be widely used in the circular design device, and forms a coaxial design with the take-up device, which saves space very much. Under the condition of well-designed, its maximum service life can reach 300000 times. Parameters that must be provided for the design of take-up spring: 1. Inner diameter of installation box (d) 2.

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...

Uporaba vzmeti s konstantno silo v medicinski opremi: A support device for assisting a patient is used to assist the movement of a patient at the patient support device. In the prior art, a caregiver would operate a patient lift or motor by guiding the lift to raise or lower the patient at the patient support. Such manipulations often require the precise manipulation of heavy forceps and motors by a paramedic to help the patient move around the patient support. The support means may incorporate a constant force spring design, the support structure comprising a base and an upper portion extending upwardly from the base. The constant force spring assembly may include a carrier slidably coupled to the base secured to a first end of the carrier. The base may include channels that guide sliding movement of the carrier relative to the base of the support structure. The constant force spring assembly may also include a spool and a motor configured to drive the spool. The auxiliary belt may be secured to the spool so that the auxiliary belt is wound and unwound from the spool in response to a motor driving the spool. And the motor can be fixed to the carrier to move with the carrier. Constant force springs get their name because their motion force is constantly applied. The load is determined by the width and thickness of the material and the diameter of the coil. The tightly wound rollers work in a linear motion, not obeying Hooke's law (F=kX), but constantly generating forces as they deflect.These springs provide...

Today we’re going to talk about the connection between the constant force/tape spring and the tilting double or single hung window.: Today we're going to talk about the connection between the constant force/tape spring and the tilting double or single hung window. As we know, hung windows feature a balanced application to counteract the weight of the sash, allowing the user to position the sash at the desired opening height. The balanced application also enables users to open and close windows with minimal effort. Actually, the constant force/tape spring is a somewhat hidden component sitting inside the window frame of the tilting double or single hung window, it is the balanced application, sometimes called a sash balance, window spring, or window "balancer". Window balances are only found in double-hung or single windows and counterbalance the weight of the sash assisting you with opening and closing your windows. If your window balances are damaged or broken, your window may be difficult to open, not open at all, or may not stay open. Qianye Springs (Qianye Precision Spring Technology Co., Ltd) provide the high-quality constant force/tape springs. All our springs are made of 301 stainless steel which ensure the springs are durable and long-lasting. More info：https://www.qianyespring.com/ mail: leah_lee@qianyejm.com Whatsapp: +86-181 7563 3483
