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 og funktion af tvillingfjeder eller motorbørstefjeder

 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...

Constant Force Springs Design Guide

There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a smooth range of motion and a constant load. Learn more about this type of spring to see if it could work in your device or application. Constant Force Spring Benefits There are many benefits of constant force springs that make them suitable for a number of applications: Have small space requirements Provide a smooth range of motion Have no inertia to overcome Mount to existing hardware Produce a counterbalance effect For these reasons, constant force springs are versatile enough to work for a number of applications in which a constant load is required to counterbalance, tension, retract or dispense. This is why they’re frequently used to enhance...

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...

Anvendelse af fjedre med variabel kraft i detaildisplays

Variable force springs are very common in the point-of-purchase or POP industry, especially in shelf pushers. Variable force springs provide variable force to precisely match increasing or decreasing force requirements, propelling the product horizontally forward. Due to their wide applicability, these springs can be seen in the tobacco, cosmetic, electronics and medical industries. So why use variable force springs in shelf thrusters?       1. Inventory Control        Variable force springs are commonly used in trays that push products forward in a controlled manner. Variable-force springs in the push-in trays aid product fronts, so the shelves are always well-stocked. These trays allow for more organized store inventory and help track inventory needs. 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...
