Constant force springs applied in wall mounted accessories

Время:2022-9-14

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, because the balance mechanism allows the bracket to move a larger vertical distance for vertical position adjustment. The constant force spring is used to balance the weight of the accessory, screw balance, pulley balance or other low friction devices installed on the accessory retainer by engaging with the roller assembly. The roller assembly can be raised or lowered by the user along the track with minimum force. The weight of the mounting accessories supported by the roller assembly is basically balanced by the balance mechanism. When the user moves the roller assembly vertically up or down, the constant force spring is wound or unfolded...

Применение пружины постоянного крутящего момента в 3D-принтере

Время:2022-9-14

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...

Power spring used in automobile safety belt

Время:2022-9-14

Safety belt is equal to life belt. Everyone should see the painful accidents caused by not wearing safety belt. I believe everyone is familiar with the car safety belt. It is a safety device to avoid rushing out of the car during collision and causing death and injury. Automobile safety belt is recognized as the cheapest and most effective safety device, and it is also a necessary safety configuration. In a typical safety belt system, the safety belt is connected with a retractor. The core component of the retractor is the reel, which is connected with one end of the safety belt. Inside the retractor, with the help of the action of the power spring, the webbing can expand and contract freely with the movement of the user's body without loosening the webbing. In case of emergency braking, collision or sharp change of vehicle driving state, the sensitive element in the retractor will lock the reel to fix the webbing at a certain position and bear the load imposed on the webbing by the user's body. The power spring is made of rolled steel strip. A spring box is required to limit its outer diameter in use. The center of the spring is connected with the shaft. When an external force is applied to make the shaft rotate relative to the spring, the spring will roll on the shaft center and store torque. When the external force disappears, the spring will produce torque on the shaft or spring box. Qianye has made technical product updates for power springs. First of all, our company...

How long can constant force spring be used ?

Time:2022-9-15

Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.     Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the things behind the design ; improper consideration may lead the design to a wrong direction ; properly considered, the design will be easier to succeed. It is very important to determine the number of spring stretching before designing the constant force bar. Spring stretching times explanation : a refers to the spring in any part of a stretch and roll back process. Since the constant force spring provides force through the bending of the spring, any part used belongs to the spring body. In other words, a spring with a total design length of 25 ’ uses the length of...

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...

Традиционные силовые пружины и пружины с предварительным натягом

Время:2022-9-14

   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, 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...

A constant torque spring can play such a big role in the take-up device

Время:2022-9-14

Constant torque springs can help take up the wire and are used in many products. All electrical products have a cord set that is connected to the power supply, but this power cord will bring some trouble to our arrangement. The function of the constant torque spring is this, it can bring a free shrinkage process to the electrical cord set , making it easy to take up the line, very practical. When the external force reverses the constant torque spring from the natural state to the output wheel, once the external force is removed, the constant torque spring will be rolled back to the natural state, and a constant torque will be generated in the output wheel at the same time. Constant torque spring can be used in automatic winding, balance weight and power source, such as automatic winding device of power line. Advantages of constant torque spring over power spring: 1. The torque will not change as the number of turns increases. 2. There is no limit on the number of available turns, and the design of multiple turns mostly adopts constant torque spring.  3. The number of invalid turns is less, more energy can be stored and the efficiency is higher. Many take-up devices on the market are prone to dislocation or jamming during take-up due to the improper selection of spring, resulting in confusion and low take-up efficiency. Shenzhen Qianye Precision Metal Co., Ltd. has been specializing in the production of spring for more than 20 years. Qianye precision spring engineers can help you improve and improve your products. Contact us at any stage of your project for expert help and technical...
