 Do you know what springs are used as stop mechanisms?
Do you know what springs are used as stop mechanisms?

Время:2022-9-14

We often find that the spring we make is wrongly used as a stop mechanism in the design. This design defect can occur in all types of springs, including constant force spring, constant torque spring and power spring. For example, consider a simple cable extension product in which the spring retracts the cable into the housing. If the spring is completely wound before the cable is fully deployed, the spring will be used as a stop mechanism. This action will damage the function of the spring and components and should be avoided at all costs. Here are some useful tips when considering the stop mechanism. Constant Force Spring Application:  Initial designs often show the inner end of a Constant Force Spring attached to its’ spool. This is not necessary.  If the spool is larger than the natural spring diameter, the spring will automatically fit tightly on the spool.  In the case when a screw is attached to the spool, additional concerns arise.  If the spring is pulled tight on the screw,  a hump will result that will not only make the retraction difficult but will cause a fracture point and reduce life cycles. To avoid this, we recommend that the spool maintain 1-1/2 wraps of spring material at the furthest extension.  If these additional wraps are not practical in the design, another method of stopping the rotation is required. Constant Torque Spring Applications:   This type of motor spring is commonly used to retract a cable or to keep a constant torque rotational force on a spool.  It is extremely important not...
 Power springs in hose reels
Power springs in hose reels

Время:2022-9-14

Transmission hoses and wires are necessary for automotive production and maintenance work, but they are time-consuming and labor-intensive to sort out after use. Another common problem is safety when handling them. This can cause serious injury if the operator is inexperienced. Bulky and unwieldy hoses are also an added risk, especially if they are too short for the job. This forces the operator to move into dangerous positions that can cause injury.   The hose reel now solves these problems by incorporating the maneuverability of the power spring, allowing the long hose to automatically retract after use and align itself continuously and neatly when retracted. In addition, considering the limitations of floor layout and staffing, the hose reel with the addition of the scrolling bar can make full use of space and improve the workplace environment. After use, the hose or wire is retracted to the winder for storage, and generally will not break, and low friction, which can extend the service life of the hose or wire. The tension on the power spring is pre-loaded at the factory, and springs produced by improperly selected manufacturers may become untensioned or over-tensioned. Too much tension can lead to fast and violent retraction as well as a short life span, and the elasticity can fail quickly.   Therefore, it is recommended that manufacturers of hose reels look for high-quality spring manufacturers, because the current reel winding function of the emergence of a deep expansion of the advertising market, so that more electrical products are constantly in the upgrade to create new product selling points. Choosing the right...

"Constant force spring" is a necessary component for cable accessory manufacturers at home and abroad

Время:2022-9-14

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...
 Power spring in the design of the car covers
Power spring in the design of the car covers

Время:2022-9-14

Car covers are commonly used automotive protective articles, but the folding and storage of car covers is a troublesome thing. In order to solve this problem, invention lovers have done a lot of useful exploration and put forward many solutions. One kind of scheme is to use power to drive the reel to directly roll up the car cover cloth. Using the reel to directly roll up the car cover cloth can achieve the purpose of rapid retraction of the car cover, but there are the following problems in actual use: first, the winding and friction of the reel when directly rolling up the car cover cloth wear the car cover cloth greatly; second, in order to adapt to the width of the car cover cloth, the width of the car cover retracting device must be close to the width of the car cover cloth. If it is too narrow, it will increase the winding of the car cover cloth, so the shape of the car cover retracting device is larger, It reduces the convenience of use: Third, it may not be able to completely stow the hood cloth. Only one power spring is needed to solve the above series of problems. The power spring designed by Qianye precision can be applied to the car cover. The power spring retracts the car cover to realize the rapid retraction of the car cover. At the same time, it solves the problems of large wear, large device shape and high operation intensity caused by the direct retraction of the car cover cloth by the reel, as well as the problem...
 Constant force spring in vehicle ashtray
Constant force spring in vehicle ashtray

Время:2022-9-14

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,...
 Fire damper spring
Fire damper spring

Время:2022-9-14

Fire dampers are valves that are used to block the passage of smoke and flame from fires and meet the requirements of fire resistance stability and integrity within a certain period of time. In order to minimize the loss caused by fire, it is necessary to take effective fire and smoke prevention measures to control the spread of fire while the fire damper is ventilated. Reasonable settings in the air conditioning and smoke exhaust system play an important role. The operation of fire dampers is simple: when the temperature of a room or space rises above a threshold limit, they close to prevent the fire from spreading. Fire dampers have fuses and can be selected according to the required temperature. Once this temperature is reached, the damper closes.    The damper itself can be electric, pneumatic or manually set. In electrically and pneumatically actuated dampers, a fuse releases and cuts off the operating voltage of the spring-return motor, causing the spring to close the damper blades. After replacing the fuse and re-establishing the operating voltage of the motor, the fire damper opens automatically. In a spring-operated damper, a fuse release allows the spring to close the damper blade. After replacing the fuse, the fire damper must be manually reset to the open position. Design of fire damper spring:   The advantage of the spring designed by Qianye is as follows: Although Qianye precision can not directly prevent the initial occurrence of fire, we have created customized springs for the life support function of fire dampers. In turn, our spring-loaded dampers provide ventilation...

Dampers are widely used in building structures to dissipate energy and reduce vibration. However, the traditional damper has complex structure, poor durability and corrosion resistance, and low working stability. After using for a period of time, the damper is prone to aging and deformation can not be restored, so it can not be used anymore. Most of the existing dampers use shape memory alloy (SMA), which is a material composed of more than two kinds of metal elements through thermoelasticity, martensitic transformation and its inversion; Using shape memory alloy, the damper can automatically restore to its original shape after deformation, which is used for the restoration of building structures after deformation. However, the existing dampers only use the performance of shape memory alloy (SMA) wire itself, and the cost is expensive, which is not conducive to the large-scale use of dampers.   The design of constant force spring can be added to the self resetting damper. The damper includes piston parts, U-shaped plates and moving rods. The constant force spring is set between the tension moving rod and the pressure moving rod. The constant force spring tightens the tension moving rod and the pressure moving rod to be close to each other, so that the tension moving rod and the pressure moving rod respectively lean against the end close to each other in the corresponding sliding hole. It is conducive to the large-scale use of self resetting dampers. Constant force spring is a kind of functional material with high ductility, which has the advantages of constant load, high energy storage density, low friction loss and so on....
