Detection of geometric size of 6.1 compression springs6.1.1 spring material diameter detection: check the spring material diameter generally with vernier caliper or micrometer. In particular, attention should be paid to the inspection of springs with small winding wires and annealed alloy wires wrapped by automatic spring coiling machines.6.1.2 spring free height or free length detection: the spring is generally placed in horizontal position measurement. It is allowed to be placed in erect position only when the self weight has no obvious effect on the height or length of the spring when it is...

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...

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...

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 spr...

There are three ways to use stainless steel spring to remove oil and oxide skin:1. Immerse the stainless steel spring into the plastic container with the metal cleaning agent A diluted with water (the proportion of cleaning agent A and water dilution is 1:1 or 1:2), and the time should be as follows: the spring surface should be free from oil and oxide skin to restore the metal color. The soaking time should not be too long.So stainless steel spring surface has matte effect.2. In the ultrasonic equipment, the proportion of cleaning agent and water is about 1:30. It is advisable to restore the ...

The spring relief valve is mainly composed of spool, seat, stem, spring and adjusting screw.The relief valve mainly USES spring force to press the spool on the seat.When the boiler pressure exceeds the pressure exerted by the spring on the upper part of the spool, the spool and stem are lifted and steam is discharged.When the boiler pressure is lower than the spring pressure acting on the upper part of the spool, the spool falls on the seat and the boiler stops discharging steam.The spool is a cone with a slight protrusion around the edge of the spool.When the steam opens the valve core, the e...

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.Linear springsLinear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and i...

(1) heat treatment technology for strengthening springs.1) protective atmosphere heat treatment. In our country, protective atmosphere heat treatment is adopted in spring, oil quenched and tempered steel wire and toughened steel whose wire rod is less than 15mm. Heat treatment in protective atmosphere can remove surface decarbonization and oxidation and improve the surface quality of materials.2) induction heating or protective atmosphere induction heating heat treatment. This process is usually carried out on the wire before forming the coil spring. Some spring factories combine heat treatmen...

1、What is Passivation?As a post-fabrication method, passivation is intended to maximize the natural corrosion resistance of stainless steel. Stainless steel is a steel alloy that contains a minimum of 10.5% chromium content by mass and along with a number of other alloys. When stainless steel is newly formed it needs to be cleaned of lubricants, oils, greases and other substances used in its fabrication. Once the steel has been cleaned it must be passivated. Passivation is a process that treats metal surfaces with an acid solution to make the surface corrosion resistant.Passive to atmospheric ...

Constant force spring, or “clock” spring, is a roll of prestressed strip which exerts a nearly constant restraining force to resist uncoiling. The force is constant because the change in the radius of curvature is constant.   Such applications as brush springs for motors, counterbalance springs for window sashes and carriage return springs for typewriters. Constant force motor springs are used to drive mechanisms for timers, movie cameras and cable retractors.Constant force spring also known as coil spring helix in a plane of the spring, Spring is the material wound into a plane of the spiral of a spring, the spring is fixed at one end, the other end of the material after acting torque bending torque, bending elastic deformation, so the spring in its own plane to p...

A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. They are usually coiled at a constant diameter, though they can be coiled in other needed forms such as conical, concave (barrel), convex (hourglass), or various combinations of these. Compression springs are used to resist force and/or store energy,1、CharacteristicsBy far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. 2、Service LifeIt should be noted that if critical force-versus-deflection linearity is required, only the center 60-80% of the available deflection range should be employed.Thus, reserve at least the first and last 15-20% of t...

When choosing the right spring, selecting the best spring wire is a critical before manufacturing. Below are some of the most common spring wire materials and their unique characteristics .Stainless Steel SpringsStainless steel springs have low-stress relaxation and resist corrosion. They have good strength at moderate temperatures and are resistant to heat. Extension springs are most commonly made from stainless steel.Extension springs absorb energy and provide resistance to pulling. As the name suggests, an extension spring stretches as a load is applied to it. Applications for extension springs include carburetors, trampolines and farm machinery.Oil Tempered Spring WireOil tempered wire is cold drawn and heat treated before plating. Ideal as a general purpose spring wire, it is often us...

springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its o...
