Stainless Steel 304 302 316 High Precision Small Compression Coil Spring


A compression spring is a helical spring that provides a force as the spring is compressed. Compression springs have several types of shapes including conical, barrel, hourglass, and the most common type of all, cylindrical. Compression springs are available with or without a grind on the ends. Compression spring with a grind will stand more square than a spring without a grind. Springs with square, ground ends will have a lower solid height than a spring with no grind.

Method for winding springs in small batches

Springs have the functions of measuring, resetting, driving, pressing and buffering, and are very common mechanical parts. Large quantities of springs are usually coiled by spring winding machines.

Small batches of springs are usually wound on a lathe without a spring winding machine, and the chuck is used as power. The mandrel is installed on the chuck mouth of the lathe. The wooden block clamps the steel wire, and the chuck or electric chuck is manually rotated to complete the winding.

Winding springs on lathes is time-consuming and labor-intensive, cumbersome, labor-intensive, difficult to control the pitch, low pass rate, and high requirements for the operator's skill proficiency. For thousands of springs in batches, it is quite difficult to complete.

The difference between stainless steel spring and ordinary spring
Comparing stainless steel springs with springs, the performance is actually the same. Both are elastic components widely used in the mechanical and electronic industries. The spring can produce greater elastic deformation when loaded, converting mechanical work or kinetic energy into deformation energy, and the deformation of the spring disappears and returns to its original shape after unloading. , Transforming deformation energy into mechanical work or kinetic energy. It is suitable for the range of anti-corrosion, temperature resistance, non-magnetic, etc.
T316 is recommended for high corrosion resistance and non-magnetic applications, but its mechanical properties are lower than T302/T304. T302/T304 is the most widely used steel because it contains Ni and has superior mechanical properties, corrosion resistance, heat resistance, and low temperature strength. It is the most commonly used stainless steel spring material. T631J1/T631 are used for heat-resistant springs and springs with high tensile strength after heat treatment, but their corrosion resistance is worse than T302/T304. There are also many options for the surface condition of the material, such as bare wire, resin-plated spring, and wire nickel-plated spring wire. Customers can choose according to the requirements of product precision and beauty.

Stainless steel springs have uniform and beautiful surface conditions, good formability, uniform elasticity, high plasticity, fatigue resistance, heat resistance and corrosion resistance. Stainless steel springs can be divided into leaf springs, spiral springs, ring springs, truncated cone scroll springs, disc springs, and torsion bar springs. According to the nature of the force, stainless steel springs can be divided into tension springs, torsion springs, bending springs, and compression springs. Ordinary cylindrical springs are the most widely used because they are simple to manufacture and can be made into various types according to the load conditions, and their structure is simple.

Generally speaking, springs should have high elastic limit, fatigue limit, impact toughness and good heat resistance and corrosion resistance, etc. The commonly used materials are referred to above. Commonly used spring wire with a diameter of less than 20 mm is cold-rolled. Some springs need to be pressed or polished after they are made to improve the load-bearing capacity of the spring.

Whether it is non-magnetic or weakly magnetic stainless steel springs, they can be widely used in home appliances, electronics, civil, industrial and other products. It is a component that is indispensable and widely used in both economic society and industrial society, and promotes the steady development of social economy.

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.
