The torsion spring is a coil spring. The torsion spring can store and release angular energy or statically fix the device by rotating the force arm around the central axis of the spring body. This type of spring is usually dense, but there is a spacing between the coils to reduce friction. They generate rotational resistance or external rotational force. According to the application requirements, design the rotation direction (clockwise or counterclockwise) of the torsion spring to determine the rotation direction of the spring.
Torsion spring is a spring accessory with relatively high precision. Ordinary spring machines that produce torsion springs cannot meet 1800 degree processing. Universal spring machines are generally used in the production of torsion springs at home and abroad. The accuracy is relatively high.
Torsion of torsion spring
When the spring is twisted, the material is stretched or sheared, such as the calculation of torsion. Therefore, the limit of the twistable angle is caused by the failure of the material. When the material is plastically deformed, it cannot be restored. Therefore, it finally comes down to the tensile strength and shear strength of the material. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can withstand. Combined with the length of the spring, the maximum allowable torsion angle can be calculated.

Custom Torsion Springs
Torsion spring is the ultimate of the variant spring, from single torsion spring to double torsion spring special torsion spring, even the deformation of various torsion bars, which can be shaped according to design. Therefore, it is difficult to grasp the necessary information of the torsion spring when designing:
(1) Free length.
(2) Control diameter: (a) outer diameter, (b) inner diameter, (c) inner diameter of casing, or (d) outer diameter of round rod passed through.
(3) Wire size "wire diameter".
(4) Materials (type and grade).
(5) Number of turns: (a) total number of turns and (b) right-handed or left-handed.
(6) Torsion force: pounds deflected to a certain angle.
(7) Maximum deflection (angle from free position).
(8) The form of the end.
Please specify: material diameter (d), outer diameter (D), torsion arm length (L), free height (Lo), and other geometric dimensions, such as the guide moment (T 1 T 2 ... T j) and the corresponding sum Corresponding torsional angle (Ψ)
Product packaging: generally a certain number of transparent plastic bags, and then by the carton packaging.Of course, if you have special requirements, we can also meet them.We have several regular partners: Bosch, Petra, Hitachi, dicks, dongfeng electric, etc.We have experience working with customers from all over the world, such as the United States, India and Australia.So you don't have to worry about transportation as long as your products are in our production range.
How to choose a spring manufacturer? We can judge by inspecting the following 10 points of spring manufacturers:
1. Types of springs that can be produced.
Different types of springs require different production equipment. The more types that can be produced, the more complete the production equipment of the company.
2. Ask about the production accuracy of the spring.
The precision of producing springs represents the production technology capability of the spring factory. The higher the production precision, the more attention the spring factory pays to the quality of the products.
3. Whether there is a research and development team.
The R&D team is indispensable for an enterprise. The R&D team of the spring factory can make this enterprise develop in the direction of new processes and new technologies. ~Innovative ability
4. Whether the production equipment is imported.
Most of the domestic spring equipment is used to produce some non-important parts of the spring, the overall production accuracy is low, and there is a certain gap in product consistency. The higher the precision of the spring equipment, the higher the precision of the spring can be made.
5. Output of spring production.
The production output of springs represents the production capacity of this enterprise. The greater the production capacity, the stronger the supply capacity and the stronger the relative delivery guarantee.
6. Which manufacturers are the suppliers for?
As the saying goes, to marry a wife, you must choose the right person, and you also need to find a partner. For example, you are in the automotive industry, and Xinxiang Huispring Spring Co., Ltd. is a spring for the automotive industry. They directly supply the German Bosch company, so the product quality must be very guaranteed. This is very suitable for you. If you are making a ballpoint pen and you want an ordinary ballpoint pen spring, then this bright spring spring may not be suitable for you. You should choose an ordinary spring factory.
7. Whether there is a special testing department and whether the testing equipment is complete.
The inspection department is a necessary department of the spring enterprise. If no one supervises quality control, or quality control cannot use effective equipment for inspection, then no one would dare to use such products.
8. What is the defective rate of the spring produced? ,
The defective rate of springs of qualified spring manufacturers is generally between 5 and 12 parts per million. This data contains the data of nonconforming products detected by the manufacturer. The smaller the data, the stronger the accuracy and consistency of spring production.
9. Where are the raw materials of the springs purchased and whether they are inspected plate by plate.
The production process of the spring is very important, and the raw material of the spring is more important. For the same material, some material dealers sell it for 5 yuan, and some material dealers sell it for 10 yuan. Why is this? On the one hand, it is the consistency of the steel wire, such as some places where it is thick and some places, on the other hand, whether the composition of the spring material is evenly distributed and whether the content is qualified. The spring produced by unqualified spring raw materials is also unqualified, such as frequent breakage or deformation, and the spring load cannot be reached.
10. Whether it has the qualification certificate of the relevant industry.
For the spring industry, are some certificates very difficult to obtain, such as IATF16949 and GJB 9001C. These are very rare certificates. If this spring company has these qualifications, at least it proves to be very formal.
Finally, we still have to conduct on-site inspections and see how much the registered capital of this spring factory is, so as to avoid subsequent supply problems.
