Una molla a coppia costante può svolgere un ruolo così importante nel dispositivo di raccolta

Ora: 14-9-2022

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...

   Variable force springs and variable torsion springs can expand negative gradients and positive gradients to form a single spring. It breaks through the influence of the traditional spring affected by Hooke's law, so that the stroke and force are no longer proportionally increased, but accompanied by various elastic force-displacement combinations, such as negative slope. Therefore, a stepped constant force can be achieved. Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications. What products can the curve changes of variable force springs be used for?      Pen Type Drug Syringe Application The spring exerts a constant force to keep the drug flow in place, preventing patient discomfort during use. It has a stretch at the end of the stroke to ensure that all of the medication can be fully injected.      up and down sliding door     When the door is closed, the spring force is less than the door weight; when the door is in the middle stroke, the spring force is equal to the door weight. When fully open, the force applied by the spring is greater than the weight of the door to ensure the door does not slip.      Shelf pusher      The spring outputs a variable force to match the number of displayed items. A large thrust can ensure that a large number of displayed items can be pushed smoothly, and a small thrust can effectively push small-quality items to avoid flattening of the exhibits.      Cordless curtains     Variable torque...

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 selected. Variable force springs allow most products to be pushed with a consistent force regardless of item weight. At Qianye Precision, we understand the importance of displaying products in high-end retail spaces. We take this into account in every design.         3. Customer Satisfaction Variable force springs make shopping easier for consumers because products are displayed in a more organized and aesthetically pleasing manner. Products include cosmetics, nutraceuticals and pharmaceuticals, beverages, food, and anything suitable for retail display.         In terms of the design of the variable force spring under consideration, because the force...

[Qianye precision]Spring on motor car curtain

Ora: 14-9-2022

When taking the high-speed railway, everyone should like to look at the scenery outside the window. I don't know if you have paid attention to the curtains on the bullet train. When I take the bullet train, I often find that there is no buckle on the curtain slide rail on the bullet train, but I can still go up and down freely and won't fall or bounce back. That is to say, when I pull down 1 / 3, it will stop at 1 / 3, and when I pull down half, it will stop at half; If you want to put it away, just push it up and stop where you push it? It's different from the curtains I usually see at home. Isn't it affected by gravity? With this curiosity, let me show you that the bullet train should be a spring roller shutter. The elasticity of the spring roller shutter can adjust the rise and fall of the fabric within a certain range and can stop at any position. Gently pull down and let go. The fabric can bounce back to the top of the curtain leisurely and freely. The operation is light, the operation time is short, and the stay position is arbitrary. Compact structure, flexible and convenient operation. Because the addition of variable force spring makes the roller shutter achieve this effect, many variable force springs on the market can not achieve the effect that the force is changing in any section, so many electric roller blinds will add some components (deceleration device, damping device, this...

Do you know what springs are used as stop mechanisms?

Ora: 14-9-2022

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...

Lo sapevi che basta una sola molla per risolvere il problema del parcheggio delle biciclette?

Ora: 14-9-2022

 Nowadays, the quality of life is getting higher and higher. Bicycle no longer exists as a means of transportation, but has become a fashionable fitness product. People who play with cars have a saying: if you want to keep your car, you don't need a car lock. Where do you put your car when you get home? Especially for people like me, who have two children and are very short of room, where to put the bike at home has become a headache.      In order to solve this problem, foreign designers have designed a parking rack, which can easily save you 40% of the use space in one step, and it is very labor-saving. The traditional hanging frame requires you to lift the car hard before you can put it on. As long as you push the hanging frame to the card slot, the hanging rack will rise automatically, and even the elderly can hang the car easily, When you need to ride, just pull your car back and the hook will fall automatically.      Of course, some people will certainly ask that there is a sensor. In fact, it is not so complex. There is a small mechanism inside and a long spring in the wall. Through the tension of the spring, your bicycle can automatically lift and lower. Some people must want to ask that a spring can be so harmful? Today brings you into the world of springs.      Spring is a kind of mechanical part that uses elasticity to work. It can...

Nove fattori a cui prestare attenzione nella produzione primaverile

Ora: 14-9-2022

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...

What do you think when you see the fire damper? I believe many people will think of "fire". In fact, the word "fire" must be familiar to everyone! What do you think of when you hear this word? People trapped by the raging fire? Or the scene of our brave firefighter uncle fighting the fire? The following are the fire events in recent days. At 14:00 on March 12, 2022, a fire broke out in the oil fume pipeline of a hotel in Huazhou City. At 3:46 on March 8, 2022, a fire broke out at the construction site of Jinke Xiangsheng Yueyuan at the intersection of chegang road and Xiyun road in Zhenjiang new area. In the early morning of March 14, 2022, a fire broke out in Kundulun District of Baotou City, which has killed 7 people so far. Do you feel very sad at this time? Uncontrolled fire is always a serious risk. In an emergency situation a fire can spread via a ventilation ductwork. Therefore it is essential that the ventilation ductwork is equipped with high-quality and robust fire dampers that also prevent smoke from spreading and therefore enable safety for escape routes. But what is a fire damper?     Fire Dampers are used in air transfer openings, ducts and other places where fire rated structures (e.g. walls, floors or other fire barriers) are penetrated. If these openings wouldn’t be protected, the fire would easily spread to other spaces and damage the property and pose a danger to people working/being in this environment. The idea...
