L'importanza delle molle per l'industria aerospaziale
L'importanza delle molle per l'industria aerospaziale
       Springs are an important part of many different industries, including the aerospace industry. They form the backbone of many components and allow planes, drones, satellites, solar panels, aircraft controls, valves, throttles, and more to function their way. Without the spring, the industry would not be the same. Strict military and aviation guidelines mean that all components of the aircraft, including the springs, must be of the highest quality and precision; they support a wide range of applications and reduce part weight while maintaining the highest performance standards. This makes springs vital to the aerospace industry. Without springs, we wouldn't be able to have the essentials of aerospace. For example, retractable tray tables, trunk doors, handrails, stairs and cup holders require springs to function. They help open and close many components that wouldn't exist without them—and, more importantly, springs are some of the main elements of aircraft landing systems. They are also present in satellite dishes and probes...

How to solve the problem of fan lifting function by dint spring

Ora: 13-9-2022

We all know that gravity of the earth's center will drop rapidly to the bottom point when the object has no support, and it will be heavy when it rises. Similarly, when the fan moves up and down, it will also be affected by gravity. Therefore, we all hope that the fan will be more light when it is lifted and lowered; it can be easily moved up and down by hand to locate at will, and the fan will be more arbitrary when using it. Therefore, to achieve the purpose of light and arbitrary positioning, we must solve the problem of gravity There are several main points for the fan to rise and fall: 1. Life problems: Each kind of hair will have a certain life cycle. If you choose the general materials and immature production technology, the life of the products will be greatly reduced. The same with the elastic problem of hairpin, they are all related to materials and processing technology. In the process of using the fixed force, there will be problems of too short life,. 2. Elasticity: In the limited space, under the same size conditions, in order to make the hair to meet the strength requirements, we must strengthen it from two aspects to better play the effect.

Ora: 14-9-2022

 With the development of society, buildings and roads are the cornerstone of the development of human society. People will choose to lay waterproof materials during waterproof maintenance, but people face some problems when laying waterproof materials. When laying waterproof materials, people inadvertently trample on the materials because they do not know that the materials have been laid, resulting in uneven laying of materials and economic losses. Therefore, we need to protect the sites under construction and just completed construction when laying. Many of the existing protective devices are large, which is not conducive to people's carrying, and the protective devices can't be seen by people at night, causing people's damage. The laying of water-proof materials is wasted, and the placement of protective devices is unbalanced, causing collapse and damage to people.   The utility model relates to a wet laying waterproof coiled material construction protective device equipped with a power spring, which can solve the above problems. The power spring requires a housing to limit its outside diameter. The spring stores force during the rotation of the power spring relative to the central axis of the spring housing. When the force disappears, the power spring will produce a torque on the central shaft of the spring housing.   The protective device comprises two expansion columns 1, a contraction device 21, a second fixing block 4 and two expansion columns 1, one of which is provided with a contraction device 21. The retracting device 21 is composed of two rotating discs 12, the first fixed column 13 and the power spring 14. The rotating disc 12 is installed in the...

Design and manufacturing method of constant force spring

Ora: 14-9-2022

 Design and manufacture a complete set of constant force springs for a variety of applications in almost all industries, from medical care to aerospace and general household products. The constant force spring is different from the traditional spiral wound spring. They are made of pre tensioned high-yield metal strips (usually stainless steel) rather than wires. Constant force springs are classified as "tension springs". When winding, the metal strip resists uncoiling with nearly constant resistance. When extended, the internal stress of the metal resists any load force at a nearly constant rate. Once the spring extends to a length of 1.25 times its diameter, it reaches full load and produces a nearly constant force. According to the size of the spring and the load it supports, the fatigue life cycle of the constant force spring is between 2500 and 1000000 times.     Constant force springs are commonly used in automotive engineering, aerospace engineering, medical and retail. Some common applications are: Cable retractor, motor, spacecraft, fitness equipment, door closer, hose retriever, nuclear magnetic resonance scanner, X-ray machine, point of sale display, toys, furniture accessories, retractable tape measure or dog line, retractable vacuum cleaner line, etc.     If you choose a constant force spring for an application, you must first consider several factors. Material selection is important, as is the thickness and width of the metal strip. The most commonly used metal is grade 301 stainless steel because it can make consistent high-quality and strong constant force springs. Other materials are available, such as high carbon steel, Inconel, etc., which may...

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...

Don't expect the bridge section of the dog looking for the master in the movie to happen. Before using this kind of traction rope, I always used a fixed 1.5m long rope. Usually I use the traction rope to prevent dogs from running around and attacking pedestrians. But there was once a time when walking a dog. Now many shared bicycles and electric vehicles often shuttle back and forth at a fast speed when walking around the corner. An electric motorcycle brushed past the dog. Fortunately, after the rope was shortened, it was able to effectively protect the dog and prevent accidents. However, many friends would say that it would be good to buy a shorter rope? But in fact, many times we need to give dogs enough range of activities, so this time can reflect...
