The spring in the timer

وقت: 2022-9-14

Timer is a precise timing device, which uses mechanical clock to drive the switch. Its time positioning is very accurate, and it can achieve such effect. Spring plays a great role in it. The emergence of timers has brought great changes to our lives. At first, we used the hourglass to determine the time. In modern life, timers have been widely used, enabling people to control time more easily, and even have been applied in military aspects such as time bombs and time detonators. The timer mainly includes three parts. The first part is the power component, spring one-way mechanism, can only tighten, not loose. Tightening the spring provides power for the whole system. The second part is the release component. By a series of gear speed, the number of rotation cycles increases when the spring is relaxed. At the end of the gear system, there are grab wheels, grab claws and swimming wires to ensure that the gear system rotates at a constant speed driven by the spring. There is a device on the swimmer to adjust the length of the swimmer to adjust the swing frequency of the grab claw to ensure that the gear rotates at the set speed, and the tightened spring won 't be loosened at once, nor is it affected by the spring tightness resulting in changes in speed. The third part is timing trigger device, so that a gear in the gear group turns to a certain angle to send a mechanical signal, control interruption. When the timer is screwed to a certain...

Design cordless curtain springs

وقت: 2022-9-14

There are many types of curtains on the market today, such as Venetian blinds, Roman blinds and honeycomb blinds. When the curtains are lowered, the windows can be shaded to reduce light entering the house and improve privacy. Generally speaking, curtains are provided with control ropes, which can drive the bottom rail of the curtain to rise or fall. In particular, the bottom rail is raised by a roller take-up hanger, and the hanger can be extended from the roller so that the bottom rail can be lowered.        However, the problem that the control cord may restrain children has been noted, so a cordless curtain has been developed. This cordless curtain can raise and lower the bottom rail by means of a coil spring box. Coil spring boxes used in window blinds usually consist of multiple springs that provide torsion to maintain the bottom rail at the desired height. However, the assembly of such a coil spring box is usually complicated, and the torsion force of the spring must be transmitted to the drum through a plurality of moving parts, which disadvantageously increases the weight of the coil spring box in the curtain.        Therefore, a cordless spring component developed by Qianye Precision can overcome the above shortcomings. Cordless roller blinds can balance the roller blinds at any position under the action of the spring components according to the high and low positions of the roller blinds, and achieve the purpose of stopping at any time. At the same time, the same effect can be...

As the building access door of modern plant, the industrial door must be familiar to everyone. The industrial door has a variety of lifting door modes. It slides upward according to the track installed on the wall, which is fast and stable. At present, the industrial door mainly uses the torsion spring balance system to stabilize the industrial door in the process of operation, so that it can be opened quickly.   Principle of torsion spring balance system: torsion spring balance is the principle that the weight of the door body is balanced by the torsion torque of the torsion spring. The torsion spring balance system of industrial doors is mainly composed of supporting seat shaft, spring, wire hub, steel wire rope and other components, in which the material of torsion spring is more important. Generally speaking, the torsion spring of the torsion spring balance system needs to be made by computer-aided design and professional equipment.   Industrial door balance system analysis what are the small problems of torsion spring balance? In practice, it is difficult to meet the standard requirements due to the influence of spring material and manufacturing process. When the area and weight of the door are increased, the diameter of the torsion spring and the diameter of the steel wire will be thickened, which will affect the sensitivity of the balance of the torsion spring and increase the difficulty in adjustment. The installation of torsion spring balance on the door opening with large height width ratio increases the difficulty in designing the torsion spring balance due...

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...

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 surgical devices, deploy and retract doors on aircrafts, and counterbalance windows.   Design Considerations If you decide that constant force springs are ideal for your application, here are some considerations to think about in the design phase of your project. Load Conditions Constant force springs produce a force as the material is extended. Constant force springs are rated at a maximum operating length. This means that the maximum travel must be lower than the difference between the spring’s unextended length and maximum safe operating length. Material Another important design consideration is material. 301 stainless steel is commonly used for standard-issue...

 "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 stainless steel, which in turn resulted in hydrogen embrittlement and eventual spring failure. Additionally, mechanically exposing all surfaces of the spring to acid can damage the spring, resulting in changes in force/torque output or defects. There are better, simpler, cheaper ways to avoid any need for corrosion and passivation of stainless steel components, and it's as simple as choosing a fussy material. Remember that the risk of corrosion of any stainless steel component is driven by the environment (such as the presence of water and other chemicals) and Qianye Precision typically uses high quality 301 stainless steel for our springs....
