Passivation 0.2mm Compression Coil Spring For Elevator

High Quality Compression Springs For Elevator China Custom Made High Precision Steel Coil Springs Compression Springs​

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.

Application of compression springs

Aviation, automotive, motorbike, bicycle, automatic equipment, household appliance, medical device ,toy, telecommunication, computer, instrument and meter, furniture, electric tools, mold and other industries.

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.

Automotive spring introduction: progressive spring

This kind of spring is usually designed with inconsistent thickness and density. The advantage is that when the pressure is not large, the part with a lower elastic coefficient can absorb the fluctuation of the road surface, thereby ensuring the comfort of riding. When the pressure is increased to a certain level, the thicker part of the spring plays the role of supporting the body, but its disadvantage is that the control experience is not direct and the degree of control is poor.

Automotive spring introduction: linear spring

The thickness and density of the linear spring from top to bottom are unchanged, and the elastic coefficient is a fixed value. This kind of spring design can make the vehicle obtain a more stable and linear dynamic response, which is beneficial to the driver to better control the vehicle. It is mostly used for performance-oriented modified cars and competitive vehicles. The disadvantage of course is that the comfort is affected.
In addition, some racing cars and modified cars will add a thinner and softer small auxiliary spring to the harder linear spring. This combined spring can not only increase comfort, but also reduce the rebound force when the main spring is compressed and rebounds. , To prevent the main spring from leaving the spring seat.

Automobile spring introduction: short spring
The short spring is shorter and stronger than the original spring. The installation of the short spring can effectively reduce the center of gravity of the vehicle body, reduce the roll generated when cornering, make the cornering more stable and smooth, and improve the vehicle's cornering maneuverability. The damping setting of the original shock absorber is comfortable, so the short spring and the original shock absorber are not very stable in cooperation. It cannot effectively suppress the rebound and compression of the short spring. When driving on a bumpy road, it will There is an uncomfortable sense of jumping. If things go on like this, the life of the shock absorber will be greatly shortened, and there may be oil leakage. Of course, the above conditions are relatively speaking, there will be no such serious damage in daily driving, and try not to drive violently, after all, the original shock absorber cannot withstand the pressure of high load.
Replacing short springs is a more affordable modification solution for lowering the height of the vehicle. It is a good choice for those who have a small budget. Of course, you get what you pay for. Short springs have limited improvement in handling performance, and there are many disadvantages. , So you must be clear about your purpose when buying, otherwise the installation will not achieve the expected effect at that time, causing unnecessary waste.

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.
