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

In order to prevent accidents caused by excessive wear of the carbon brushes on the collector device of the slip ring brush holder of the wind turbine, a normally closed switch-type alarm unit is configured for each carbon brush, and these alarm units are connected in series to the alarm. In the prior art, the grounding brush is held on the structure using a coil spring pressure finger lever structure. In order to ensure sufficient pressure after the carbon brush is worn, the initial pressure of the spring has to be increased, which aggravates the wear of the carbon brush. However, in the later stage of carbon brush wear, the tension of the coil spring becomes insufficient again, resulting in poor contact between the carbon brush and the slip ring, frequent beating, resulting in breakage; at the same time, from the carbon brush to the alarm unit, the intermediate link is complex and easy to Lead to false alarm or no alarm, reducing the...

 What are Torsion Springs and How Do They Work
What are Torsion Springs and How Do They Work

Time:2023-3-6

Torsion springs are mechanical components that store and release rotational energy. They are used in a wide range of applications, from simple door hinges to complex machinery. Torsion springs work by twisting or rotating around their center axis, generating torque or rotational force.   The basic design of a torsion spring consists of a helical coil of wire with arms extending from each end. The ends of the arms are attached to other components, such as a shaft or a hinge, which creates a rotational force when the spring is twisted. When the torsion spring is rotated, the coils wind up, storing potential energy. The stored energy is then released as the spring unwinds, generating torque in the opposite direction.     The amount of torque generated by a torsion spring depends on several factors, including the wire diameter, coil diameter, number of coils, and the type of material used. Thicker wire diameters and smaller coil diameters will produce stronger torsion springs, while a larger number of coils will produce a weaker torsion spring. Materials commonly used for torsion springs include high-carbon steel, stainless steel, and music wire.   Torsion springs are used in many different industries and applications. They can be found in everything from automotive suspensions and aerospace systems to garage door hinges and mousetraps. Torsion springs are often used in applications where space is limited, as they can generate significant torque in a compact package.   Overall, torsion springs are an essential component in many mechanical systems, providing rotational force and energy storage capabilities. They come in...
 Nine factors that should be paid attention to in spring production
Nine factors that should be paid attention to in spring production

시간:2022-9-14

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...
 Power springs used in recoil start systems
Power springs used in recoil start systems

시간:2022-9-14

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

The constant force spring is made of stainless steel strip. The high strength steel strip is shaped by specific spring production equipment. When the external force is straightened, the hair strip will naturally roll back and produce elastic force. However, to achieve our goal, we can return to the designated starting point after displacement.     Constant force spring has the characteristics of maintaining constant force in a long stroke. Its function can be applied to the adjustment of lifting doors and windows, computer monitors and fans, shopping mall display shelves or motor carbon brush motors and other products that require linear motion such as round trip, sliding, stretching, homing, balance or force saving. So how to design the constant force spring in line with product performance ? We generally need to consider from two aspects :     1. Performance of constant force spring    The two most important properties of the constant force rod are elastic value and life. The thicker the elastic               material, the wider the width, the higher the elastic force. Among the materials with the same size, the smaller the     crimp diameter is, the higher the elasticity is, and vice versa. On the contrary, under the same manufacturing             conditions, the thinner the material is, the better the life is. In the same size of the material, the smaller the coil diameter is, the shorter the life is, and vice versa.     2. Installation space of constant force spring    Generally, the outer diameter of the spring...

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...
 Variable force spring in drug delivery device
Variable force spring in drug delivery device

시간:2022-9-14

Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles. Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles. Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed).   The problems caused by conventional coil springs in drug delivery devices can be overcome by variable force springs. A novel device for delivering drugs, which includes an elastic member (60), a driving mechanism (50), a holding mechanism (40) and a starting mechanism, the driving mechanism has one end connected to a stop and a second end operably connected to the elastic member, the holding mechanism is used to loosely hold the driving mechanism in the first position, where in the elastic member has accumulated energy, The starting mechanism is operably connected to the holding mechanism for releasing the driving mechanism...
 Fall Arrester using Qianye power spring
Fall Arrester using Qianye power spring

시간:2022-9-14

The fall arrester is also called the speed difference device, which is a protective product. It is suitable for safety protection when the crane is hoisted to prevent the suspended workpiece from accidentally falling. It can effectively protect the life safety of ground operators and the damage of the suspended workpiece. It is used in metallurgical automobile manufacturing, petrochemical industry, engineering construction, electric power, and ships. , Communications, pharmacy, bridges and other high-level workplaces. The protective effect of the protective device product must pass. The power spring has a retractable function and is an ideal part of the gravity dissipator used in the dropper. The anti-fall system is connected between the fixed points of the cable harness, and they can stop the user from falling in the first time. Even when the power spring is fully deployed, the gravity dissipator of the dropper can prevent the user from being hit in the event of a fall. The advantages of Qianye power springs are divided into natural power springs and pre-force power springs according to their relaxed shape. In contrast, the pre-force type power spring can store 25% to 55% more torque and provide more effective turns. When using Qianye power spring as its parts in normal use, the safety rope will expand and contract freely with the human body. Under the action of the mechanism in the device, it is in a semi-tensed state, so that the operator has no sense of worry. In the event of a fall, the pulling speed of the safety rope will be significantly increased,...
 Application of springs in industrial doors
Application of springs in industrial doors

Time:2022-9-3

  The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.        Constant force springs are often used to provide balance to products, so what is balance?        Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke's law. Hooke's law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched - multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction.        Hooke's Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can be...
