The technological process of helical springs refers to the process of converting spring materials into finished springs, which flow through every process in sequence. Because of the spring material, the spring type and the processing method are different, the technological procedures of the spiral spring are also different. However, their basic technological processes are coil spring heat treatment end processing surface treatment.Next, introduce several typical processes.1. manufacturing compressed spiral spring with cold drawn spring steel wireFor the lathe coil spring, after the winding spring process has to be cut off, a spring connected to several springs is separated into a single spring.Some important springs can add a blank height classification procedure before grinding the face t...

Wire forming spring is a mechanical part that uses elasticity to work. It is usually made of spring steel. It is used to control the movement of machine parts, to mitigate impact or vibration, to store energy and to measure the magnitude of force. It is widely used in machines and instruments.The spring is just an accumulator. It has the function of storing energy, but it can not release the energy slowly. To realize the function of releasing slowly, it should be realized by "Spring + large transmission ratio mechanism", which is common in the mechanical meter.Spring is a kind of elastic element widely used in the mechanical and electronic industry. When the spring is loaded, it can produce large elastic deformation and transform the mechanical work or kinetic energy into deforma...

The corrosion of spring can be divided into chemical corrosion and electrochemical corrosion according to the type of reaction.They are the result of changes in the metal atoms on the surface of the spring or the loss of electrons to an ionic state.If the metal on the surface of the spring simply reacts with the surrounding medium, and the spring causes corrosion, it is called chemical corrosion.For example, the spring is oxidized in the particularly dry atmosphere to form an oxidation film, and the spring is chemically changed with the liquid or impurity in the non-electrolyte liquid, which is a chemical corrosion.If the spring is in contact with the electrolyte solution, the corrosion caused by the action of the micro battery is called electrochemical corrosion.For example, the spring is...

A brief history of the development of Hooke's law

At first, during the experiment, Hooke found that the weight added to the spring was proportional to the elongation of the spring, and he tested his conjectures by many experiments. In 1678, Hooke wrote a spring paper, which introduced the results of experiments on elastic objects, laying the foundation for the development of material mechanics and elastic mechanics.Spring dynamometerIn the early nineteenth Century, under the premise of a lot of experimental work in the former, British scientist Thomas Yang summed up the research results of Hooke and others, pointing out that if the elongation...

Types of Springs and their Applications

Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment, take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy—think of them as analogous to batteries! The earliest spring-driven clocks appeared in the 1400s. Fast-forward some 600 years, you still have to charge the Apple Watch everyday, and it’s not nearly as fast as winding a clock…but I digress.My personal fascination with springs began with Slinkies and wind-up toys, and countless mechanical pencils were sac...

In the actual work, we often encounter that the spring cannot push the moving object to the set position, that is to say, the length of the spring's computational freedom becomes shorter.The main reason is that there is no initial compression, that is, a spring is made into a spring, which is compressed to its compression height or to its compression height (if necessary) with a greater force, and cannot be restored to its original free length upon release.Its shortened quantity is called "initial compression quantity".After repeating 3-6 times of compression, the length is no longer shortened, that is, the spring is "positioned".The spring is permanently deformed after initial compression.In practice, the spring should maintain its working length even if it is subj...

Torsion spring is a mechanical force storage structure, mainly used in ancient crossbow guns and other crossbow.The torsion spring accumulates the force through the twist or rotation of the elastic material with a relatively soft and pliable material, and makes use of it so that the projectile has certain mechanical energy.The modern torsion spring torsion bar is made of excellent elastic steel, and the form is also changed a lot, including the wire on the inner surface of the mechanical watch, the power spring in the toy gyroscope gun, as well as the torsion bar in the tank and car.Small size of the torsion bar torque large, as a vehicle shock absorber tool better.Torsion spring is a relatively high precision spring accessories, production of torsion spring with normal spring machine...

Nowadays, with the development of science and technology, spring has become a very important hardware accessory in our life. Different products use different springs, and the longest used springs can be roughly divided into: pull spring, twist spring, press spring, disc spring and plate spring.The following features of a very practical tension spring:Many different products or hooks are used to guarantee the source of the tension of the tension spring. The tension spring works in the opposite way to the compression spring. The tension spring works in the opposite way when stretching or pulling.The tension spring is usually stretched to a certain extent, even when there is no load at all, and this initial tension determines the tightness of the tension spring without any load at all.The gre...
