How to choose double torsion springs suppliers, what is double torsion springs: A torsion spring is a coil spring that stores and releases angular energy or holds a mechanism in place. They feature two legs extending from each end of the coil and are used in applications requiring torque or rotational force. This is accomplished by attaching the legs to external components. Then, as the elements rotate around the spring, the spring tries to push them back to their original position. Torsion springs come in a variety of different shapes and sizes, with different leg configurations and lengths, for a wide range of applications. Typical uses include automotive door handles, garage doors, clothespins, bulldog clips and hinges. In some cases, a single torsion spring cannot exert enough force. In these cases, a double torsion spring may be required. What is a double torsion spring? As the name implies, a double torsion spring is characterized by two torsion spring coils joined at the center to form one spring. The two coils...

Design and Function of Twin Spring or Motor Brush Spring: 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: 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...

What is passivation? Does my product need it?: "My new stainless steel product specification requires' passivation '. Do I need it?" Our answer is that you may not. That's why. Passivation is the process of protecting stainless steel from corrosion by adding an oxide layer on its outer surface. Although some stainless steel product specifications require passivation to reduce corrosion risk, most of them are unnecessary and expensive, and may damage some metal products, including flat bar springs, such as constant force, variable force and constant torque springs, all of which are uncommon products manufactured by Qianye precision. The reason passivation is not a good idea for flat bar springs is because passivation involves the use of acids and harsh chemicals to initially clean the metal as part of the process. The geometry of these spring types means that many small cracks can form between the coil layers. The acid used in passivation can become trapped in these crevices. This resulted in longer-than-expected exposure of the...

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...

This is even more critical in today's COVID-conscious environment. 2. Product Integrity Variable force springs are designed around the weight of the product they push. This ensures that the product is never slammed or damaged when it is...

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...

Constant force spring in vehicle ashtray: If the plush toys in the car are the favorite of female car owners, it is believed that the favorite of male car owners is the vehicle ashtray. Car ashtrays are indispensable car supplies for smokers. Although the vehicle ashtray is specially designed for smokers' car owners, it can also be used to place sundries for non-smoking car owners, which is very practical. When it comes to car ashtrays, I have to mention the problem of smoking in the car. In fact, smoking in the car is more dangerous than smoking outside. After all, the space in the car is limited, and the air circulation range is small. In this case, smoking will certainly cause air pollution in the car. However, at present, the utilization rate of ashtrays on many models is not very high. Most smokers' car owners pop ashtrays out of the window directly. The function of on-board pop-up ashtrays can greatly improve this situation. Now many cars have ashtrays designed under the central control and in the rear row to facilitate smokers in the car. In addition, some luxury cars also have ashtrays designed under the door handle. Most of the vehicle ashtray structures are in the shape of cylindrical cups, and the sealing performance is also relatively good. Generally, cigarette butts are thrown in. Basically, there is no smoke smell floating out, and the sealing is more humanized. Pop up ashtray riders may worry about whether the car will be a little bumpy, and the ashtray will pop up automatically. The ashtray will fly everywhere,...

Qianye constant force spring application principle: Constant force spring is made by winding the steel strip into a coil. The stress added to the spring determines its diameter, strength, and life. The action of a constant force spring is very similar to the action of stretching a ribbon. Spring stretching and rewinding, the part of the work with the spring itself circle formed tangent, as long as the diameter of the spring is certain, the force of the spring is constant. In extremely long spring designs, varying diameters have an advantage, and the tension increases slightly as the spring is stretched. However, this increase is small relative to the length of the stretch and can be ignored in many applications.Constant force spring is made by winding the steel strip into a coil.

Two aspects to be considered in designing constant force spring: The constant force spring is made of stainless steel strip. The high strength steel strip is shaped by specific spring production equipment. When the external force is straightened, the hair strip will naturally roll back and produce elastic force. However, to achieve our goal, we can return to the designated starting point after displacement. Constant force spring has the characteristics of maintaining constant force in a long stroke. Its function can be applied to the adjustment of lifting doors and windows, computer monitors and fans, shopping mall display shelves or motor carbon brush motors and other products that require linear motion such as round trip, sliding, stretching, homing, balance or force saving. So how to design the constant force spring in line with product performance ? We generally need to consider from two aspects : 1. Performance of constant force spring The two most important properties of the constant force rod are elastic value and life. The thicker the elastic material, the wider the width, the higher the elastic force. Among the materials with the same size, the smaller the crimp diameter is, the higher the elasticity is, and vice versa. On the contrary, under the same manufacturing conditions, the thinner the material is, the better the life is. In the same size of the material, the smaller the coil diameter is, the shorter the life is, and vice versa. 2. Installation space of constant force spring Generally, the outer diameter of the spring...

Spring applied to the skin stapler: In the process of skin incision suture in surgery, chest surgery, abdominal surgery and skin grafting in the burn department, manual suture was generally used in the past, but now skin stapler is generally used. The appearance of skin stapler can be regarded as a reform of traditional suture methods and an important reform of modern suture technology, which has given surgeons a good help. In clinical medicine, skin stapler is also listed as one of the medical products worth promoting. Compared with traditional suture surgery, the stapler can be used at a very fast speed, which can greatly reduce the operation time, easy operation and reduce the labor intensity of the medical staff, because the medical staff themselves are a busy group. The stapling eye of the skin stapler is close and orderly, painless nail removal and beautiful appearance. There are few side effects and surgical complications, so the skin stapler is very popular in the market and medical staff. The principle of skin suture device is actually very simple, it is a baffle plate and a push nail plate, nail box inside a spring. In fact, similar to stapler, each press is a suture, the molding nail out of the front gap, the rest of the nail box is pushed forward by the spring behind, you can continue the next suture, until the completion of the suture, completely loosen the handle, and then the stapler out of the skin. The spring inside the stapler is used with a constant force spring, so the constant force spring in line...

Application of constant torque spring in wireless radio: With the increasing attention of human beings to environmental issues in the process of social progress, green and low-carbon has become a popular new trend, and energy-saving and environmental protection technologies and products continue to emerge, which are affecting and changing our lives. Hand power generation is a green way of energy supply. The generator powered by the radio contains a constant torque spring motor. When tightening the spring, the spring is gradually wound onto the larger drum, and the mechanical energy obtained during winding is converted into potential energy and stored in the spring. When the spring is released, the stored energy passes through the gear transmission device and the rotating motor to generate output voltage, which is then adjusted by the zener diode to supply power to the radio in the form of a plug. Constant torque spring motor is a prestressed spring material belt, which forms a coil and is stored on a small storage drum. Then fix the free end and wind it back to 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 present its natural curvature, rotating the output drum and providing almost constant torque. When the spring is coiled around a smaller storage drum, a constant torque spring motor is formed. The terminal is then rewound and secured to a larger output drum. The spring part on the output drum is called the "winding part", and you can assemble the spring into a single or multiple configurations.The function...

The power source of clockwork toy — constant torque spring: Clockwork toys are not new to children, and children are also very interested in clockwork toys, because clockwork toys will walk around, or go straight or circle, which is very funny. This kind of toy design has lasted for decades. There are many kinds of clockwork toys, mainly cars and animals. They are suitable for children aged 3 to 12. Clockwork toy is the general name of motor toys with clockwork as power device. Spring is a kind of spring machine. In the spring, there is a recyclable coil spring. The principle is similar to that of a gyroscope. When the spring rotates, the coil spring inside is wrapped tightly. In short, it is to accumulate power potential energy, and then the spring returns, which naturally produces power potential energy. The clockwork toy uses a constant torque spring, which is made of stainless steel. The external force reverses the spring from the natural shape to the output wheel (energy storage). When the external force is removed, the spring will return to the natural state and generate constant torque on the output wheel, so it is called constant torque spring. Compared with the power spring, the constant torque spring has the advantage that the torque will not change due to the increase of the number of turns, and there is no limit on the number of turns available. The constant torque spring is mostly used in the design of multiple turns. The number of invalid turns is less, more energy can be stored and the efficiency is higher. When the spring is...

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

As the name implies, a double torsion spring is characterized by two torsion spring coils joined at the center to form one spring. The two coils are made of a wire wound in opposite directions, one counterclockwise and the other clockwise. The two parts work in parallel, like a torsion spring, with the spring legs normally pressing against the outer assembly, which pushes the outer assembly back, creating resistance. The shaft or rod usually passes through the center of the two coil bodies. Dual torsion springs are stronger than single torsion springs and can apply more force. The resulting force is equal to that of two separate springs combined. Depending on the application, the bridge and legs connecting the two coils can be made in...
