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...

The customized production process of spring cannot be carried out at will: As we all know, although the spring is only a small elastic accessory, it plays an important role in life, and the quality of the spring has a great impact. Most springs are customized products, so the process of customized production cannot be careless. When purchasing a spring, customers usually need to design the data of the product first, and communicate with the engineer to draw the drawing, so as to communicate with the spring manufacturer more clearly. Drawing the spring drawing is an important step before purchasing the spring accessories, and it is also an important step of customizing the spring engineering. The detail of the drawing directly affects the quality and effect of the spring products. Secondly, customers should carefully screen suppliers. If spring products are used, then spring manufacturers need to carefully screen and select suppliers that are suitable for you through comparison. There are many spring manufacturers on the Internet. It is more important to choose manufacturers with...

How long can the spring last?: How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors. 1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your...

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

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 tape that exerts a nearly constant restraining force against unwinding (Figures 1 and 2). The force is constant because the change in the radius of curvature is constant. This is the case if the change in coil diameter due to buildup is not taken into account. Long reach, constant torque and virtually no friction have led many designers to specify constant force springs in applications such as sliding doors and windows and height adjustment of computer monitors and fans, store display shelves or motor carbon brush motors . Constant force motor springs are also used to drive mechanisms for timers,...

Torsion springs: where are they used and why did you choose to utilize them?: There are many types of springs, but the most common are torsion springs. The design of torsion springs is optimized to maintain maximum rotational pressure between two surfaces, these helical or helical springs are usually adhered to the coils at both suspended ends. These ends are connected to external components, which are then rotated to apply bending stress. Unlike other springs, torsion springs are ideally balanced and able to withstand twisting, giving them a place in many industries. Made of various coated metals such as stainless steel, carbon, titanium, nickel or copper alloys, torsion springs are usually wound around a shaft to further increase its stability. The basic principle of a torsion spring is to retain energy as the spring assembly twists. When this is applied, torque is applied in the opposite direction to the deformation angle. This allows energy to be stored and released when necessary, and the torsion spring also secures the mechanism when necessary. Torsion springs are used in many applications; especially those using pop-up styles. They are used in various clamps and specific door mechanisms such as those found in CD players. One of the most obvious uses of torsion springs is undoubtedly in a mousetrap, which relies entirely on a centrally located torsion spring. They also sit in the center of traditional clothing clips. They are also used in heavier cases such as garage door balancers or car trunk opening mechanisms. Even in ancient times, primitive torsion springs were used as part of the giant catapults (or trebuchets) that were later used...

[Qianye precision]Spring on motor car curtain: When taking the high-speed railway, everyone should like to look at the scenery outside the window. I don't know if you have paid attention to the curtains on the bullet train. When I take the bullet train, I often find that there is no buckle on the curtain slide rail on the bullet train, but I can still go up and down freely and won't fall or bounce back. That is to say, when I pull down 1 / 3, it will stop at 1 / 3, and when I pull down half, it will stop at half; If you want to put it away, just push it up and stop where you push it? It's different from the curtains I usually see at home. Isn't it affected by gravity? With this curiosity, let me show you that the bullet train should be a spring roller shutter. The elasticity of the spring roller shutter can adjust the rise and fall of the fabric within a certain range and can stop at any position. Gently pull down and let go. The fabric can bounce back to the top of the curtain leisurely and freely. The operation is light, the operation time is short, and the stay position is arbitrary. Compact structure, flexible and convenient operation. Because the addition of variable force spring makes the roller shutter achieve this effect, many variable force springs on the market can not achieve the effect that the force is changing in any section, so many electric roller blinds will add some components (deceleration device, damping device, this...

Brush spring protector: Conventional motor arrangements include a rotor with windings to conduct current during machine operation. As the rotor rotates, current is conducted through the rotating elements from sources external to the rotor to the rotor windings. A rotating element such as a slip ring or a commutator contacts the brush spring to conduct current. There are two main types of brush springs, single-coil brushes and double-coil brushes. The brush springs provide constant pressure to the commutator and slip rings while minimizing brush wear, burning and scratching. They provide excellent work at high speeds for improved motor performance. The brush spring is relative to the rotating element, and the brush spring is ground due to friction during use. It is damaged and needs to be replaced periodically. So sometimes the brushes are replaced during motor downtime. To change the brushes safely, the operator uses one hand (to avoid current passing through the operator's body). Brush carriers can be heavy and unwieldy, so brush replacement is not only difficult but dangerous. A brush holder, brush handle assembly helps operators safely remove replacement brushes in electric machines or other rotating machines. A stationary support is included having at least one groove and a pronged electrical connector. The stationary support has a conductive strip for a portion of the body for being configured to pass through the stationary support. Its lead electrical piece is configured to provide electrical conductance with a collector base (collector base) and electrical fork connectors. The brush retention structure...

＂Constant force spring＂ is a necessary component for cable accessory manufacturers at home and abroad: With the increasing application of cold shrinkable cable accessories, constant force spring has become a necessary component for cable accessories manufacturers at home and abroad. How to find a suitable constant force spring in practical application? How to determine the continuous elasticity, magnetism and corrosion resistance of constant force spring has become the first consideration for cable accessory manufacturers and customers. Whether imported brand or domestic brand, the use of constant force spring for standard cable accessories has become a standard configuration, but the quality is uneven. Faults often occur due to factors such as material, type selection or performance. The corrosion resistance of constant force spring is related to the material and processing technology. The corrosion resistance of stainless steel mainly comes from chromium. The corrosion resistance of steel will be greatly improved only when the chromium content exceeds 12%, and the addition of nickel will also improve the corrosion resistance. Constant force spring for cable is generally made of stainless steel 301 in China and x12crni17 in foreign countries 7 stainless steel is made of high tensile strength and hardness during cold processing, non-magnetic, but magnetic after cold processing. After heat treatment, the magnetism can be eliminated, and the surface will turn light yellow, but the corresponding hardness will decrease. The application environment of constant force spring is the same as that of cable accessories. The outside is generally wrapped with some strips to prevent axial displacement along the cable. In the process of use, it is wrapped inside the whole joint or terminal and will not be in direct contact with moisture, but it...
