Torsion springs are one of the more complicated design principles among all spring categories, and the type changes are also quite lively, so the theory involved in the design is also the most cumbersome. Torsion springs are helical springs. The ends of the torsion spring are fixed to other components, and when the other components rotate around the center of the spring, the spring pulls them back to their original positions, generating torque or rotational force. The torsion spring can store and release angular energy or rotate the arm around the central axis of the spring body to statically fix a device. This type of spring is usually dense, but there is a pitch between the coils to reduce friction. They generate resistance to rotation or external forces of rotation. According to the application requirements, design the direction of rotation of the torsion spring to determine the direction of rotation of the spring. The circles are either tightly or separated around each other, which can be adapted to torsion load. The end of the spring can be wound into a hook shape or a straight torsion arm.

After the spring is formed, it generally needs to be subjected to low temperature stress removal annealing or blue treatment at 220 ~ 330 ℃, or according to the requirements of the operating conditions of the spring and the nature of the selected material, it needs to be hardened and tempered to improve the spring force. However, clamps should be used during the heat treatment of the spring to prevent the ring from shrinking and jamming with the shaft when working. Others, such as removing the corners of the two outer ends, radial burrs, etc., cannot be ignored. In the event of a spring with a tendency to bend, a coil of strips can be used to rub the tensioned spring along the longitudinal direction of the axis repeatedly until the surface is locally hardened. Spring is not in place, failure mode and reason: In actual work, we often encounter that the spring cannot push the moving object to the set position, which means that the calculated free length of the spring becomes shorter. The main reason is that there is no initial compression treatment, that is, a manufactured spring is compressed to its compression height or tight height (if necessary) with a relatively large force, and it cannot be restored to its original shape after being released. The free length of the operation. The amount of shortening is called "initial compression". Generally, after 3-6 times of compression, the length is no longer shortened, that is, the spring is "positioned". The spring undergoes permanent deformation after initial compression Precaution: In actual work, the compression spring should be able to maintain its working length even if it is subjected to a force beyond the elastic limit of the material. Therefore, the length of the finished spring should be equal to the calculated length of the spring plus the initial compression, which can prevent the spring from being out of place, so as to avoid dangerous stress when the coil is tightened, which may cause the spring indicator line to be abnormal and not in place. In the heat treatment process of the finished spring, especially the hardening and tempering process, the workpiece must be placed horizontally (horizontally) i

Structure Design Of Torsion Spring Design 1. The torsion spring is the extreme of the variant spring. From single torsion spring to double torsion spring, special-shaped torsion spring, and even various torsion deformations, can be shaped according to design. 2. Use on a supporting mandrel or arbor. The dimensions of the mandrel may allow a gap of approximately 10% in the listed deviations. If the deviation is large, the size of the stem should be reduced. 3. In order to make the torsion spring function in good condition, the space (minimum axial space) in the assembly must be sufficient. The minimum axial space cannot refer to the length of the coil. The torsion spring should be used along the direction of winding the coil. Because of the residual stress, the maximum load is lower in the loosening direction. 4. The torque value listed is the maximum torque recommended by the torsion spring. These values can be increased by about 20% under static conditions with a little adjustment .content_box { border: 1px solid #333; padding: 20px; } .content_box img { max-width: 100%; height: auto; } .content_box h3 { text-align: center; } Torsion spring C-382 Torsion spring C-14 Torsion spring C-119 If you are interested in torsion spring design,You can browse related products and initiate consultations on our website.

Led by the Policy Research Office of the Shunde District Committee, the Nanfang Daily and the Shunde Small and Medium-sized Enterprise Service Center jointly organized the 2020 Shunde High-quality Development Standard Inspection Group.In August 2019, shunde district party committee the 13th plenary session put forward seven times, high quality manufacturing is a core area of core components, to master the core technology, production, product quality, brand, high-end manufacturing, and decided to implement the strategy of "three nuclear projects" lead, the manufacturing in China shunde manufacture the highest quality, efforts to achieve national manufacturing industry development area in high quality, revive "shunde manufacturing, China's pride".

At 8 o 'clock in the morning of July 25, 2020, more than 100 outstanding colleagues and relatives and friends of Xin Zhaolang Company, led by General Manager Cai, took the bus to Xiachuan Island and started the two-day unforgettable trip to Xiachuan Island.  2020 is a special year. In the first half of the year, everyone was afraid of the Coronavirus. All the employees of the company united and helped each other, and under the leadership of General Manager Cai, we safely passed the dangerous period.Coming to a more challenging time, our company organized this activity to encourage all colleagues to make persistent efforts, to fight the battle in a better state, enrich the staff's spare time life, enhance the communication and cooperation between departments, make the big family of Xin Zhaolang more harmonious, so as to better enhance the cohesion of the enterprise. The whole trip lasted for 2 days, and the whole team was always surrounded by a harmonious and warm atmosphere. Xiachuan Island, known as "China's Phuket Island", is shaded by coconut trees and has charming scenery, fine natural beaches, gentle and beautiful bays, and fascinating historical sites.  On the first day, take a luxury speedboat in the vast expanse of blue waves, the sea and sky are one color, the white waves towering sky, the carefree feeling of galloping in the south of China once again ignites your passion for travel, outline the vision of Kawandao!In the afternoon, everyone was intoxicated with the blue sky, white clouds, white spray, fine silvery white beach, the Coconut Dream Corridor full of southern sentiment, and the sea reef scenery of various forms. The next day, listening to the sound of the waves, relax and sleep until you naturally wake up.The Buddha mountain park, climb on the top of the 99 steps lie across the two pieces of natural stone: one is to climb the stone, stone cliff wide have master Mr Guan shanyue's inscription, under the look to overlook can enjoy sichuan island's most prestigious "seven star moon" landscape, another stone for sound stone, tap on a different position, will produce different sound effects, why so magical, remain
