Compression spring SUS316-WPAΦ0.25 plunger spring

Compression spring SUS316-WPAΦ0.25 plunger spring

The variation in load is almost proportional to the variation in free length, so free length control with sensors is effective.

This is a spring used in the plunger reciprocating mechanism of a solenoid valve. The material used is "spring stainless steel wire SUS316-WPA." It has superior corrosion resistance compared to the general-purpose spring material SUS304-WPB and is a non-magnetic material. This spring is processed through coiling while inspecting and adjusting the free length with a sensor called "kenchouki" to suppress variations in the mounting load. The variation in the mounting load is almost proportional to the variation in the free length, making control with the same sensor effective.

Compression spring SWP-AΦ5.0 valve spring

Compression spring SWP-AΦ5.0 valve spring

Shot peening improves the durability of springs.

The material used is "Piano Wire Type A, SWP-A." The wire thickness is Φ5.0. After forming the spring with a heart gold type winding machine, it undergoes heat treatment (low-temperature annealing) and shot peening. Shot peening is a process that projects countless small steel balls onto the surface of the spring. This treatment improves durability by modifying the surface of the material. Using a spring load testing machine, we output data on the mounting load, maximum load, and spring constant, and we will provide an inspection report upon delivery. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Tsuruoka Spring Co., Ltd.

Garter spring, close-contact spring, SUS631-WPC Φ0.4

Garter spring, close-contact spring, SUS631-WPC Φ0.4

This is a garter spring used for reinforcing the seal part.

It may look like just a ring, but in fact, it is constructed by twisting the ends of a thin spring that is tightly coiled, joining them together to form a complete loop. During the twisting process, care is taken to ensure that no twisting occurs throughout the entire ring. The entire ring can stretch and contract like a rubber band, making it useful as a reinforcing spring for the sealing part. The material used is "spring stainless steel wire, SUS631-WPC." This stainless steel spring material is used when greater strength and heat resistance are required compared to the general-purpose "SUS304-WPB." To achieve the specified strength, a heat treatment known as precipitation hardening (also called aging treatment) is applied after the spring is formed. For springs of the same shape, there are processing achievements using non-magnetic and corrosion-resistant "SUS316-WPA" and iron-based spring materials such as "piano wire" and "hard steel wire." If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Tsuruoka Spring Co., Ltd.

Wave spring SUS304-WPBΦ0.8 retaining spring

Wave spring SUS304-WPBΦ0.8 retaining spring

It is used to hold the workpiece in a space-saving manner with a flat wave-shaped spring.

This is a space-saving spring used to secure work in narrow gaps. It is formed flat in a wave shape rather than in a coil shape. The material used is "spring stainless steel wire SUS316-WPA," which has better corrosion resistance than "SUS304-WPB" and is commonly used for springs in food factories and chemical plants. After spring forming, heat treatment (low-temperature annealing) is applied to relieve stress. Springs of the same shape have been processed using "piano wire (SWP-A, SWP-B)," "hard steel wire (SW-C)," and "phosphor bronze wire (C5191W)." If you have any issues with springs, please feel free to consult us. Tsurugaoka Spring Co., Ltd.

Spring load: static load and dynamic load

Spring load: static load and dynamic load

The loads applied to a spring can be broadly divided into two types: static loads and dynamic loads.

◎ Static Load The following cases apply: 1) During the use of the spring, there is no fluctuation in load (a constant load is applied). 2) There is fluctuation in load, but the number of repetitions is approximately 1,000 times or less over its lifetime. ◎ Dynamic Load Also referred to as repeated load, most springs fall into this category. The methods for evaluating the durability of springs also differ for each case. In the case of static load, the evaluation criterion is whether the material undergoes plastic deformation. The idea is that it is acceptable as long as there is no "settling" in the spring. For dynamic load, it is natural that there is no settling, and the evaluation is based on how many cycles the spring can endure before fatigue failure occurs. By the way, enduring 10 million cycles is considered equivalent to having a semi-permanent durability. The "fatigue" of metals refers to the progression of micro-cracks due to repeated loading. Typically, it does not involve plastic deformation, making it a very troublesome phenomenon that can lead to sudden failure without any prior signs of settling or deformation. This concludes a rough explanation of static and dynamic loads and their evaluation methods. If you have any points that were insufficiently explained or any questions, please feel free to contact us by phone or email.

Heat treatment of springs, low-temperature annealing, bluing.

Heat treatment of springs, low-temperature annealing, bluing.

After spring forming, heat treatment must be performed to remove residual stress.

When processing spring materials, residual stress occurs within the material. If this residual stress is left untreated, the spring will attempt to return to its original shape, resulting in deformation over time. To avoid this phenomenon (springback), stress relief heat treatment is always performed after spring forming. Higher heat treatment temperatures are more effective at removing residual stress. However, spring materials have the characteristic that their strength decreases sharply when exposed to temperatures exceeding 450 degrees Celsius. Therefore, the stress relief heat treatment for springs is conducted at relatively low temperatures ranging from 200 to 450 degrees Celsius. This heat treatment is referred to as "low-temperature annealing." (In our spring manufacturing field, we call it tempering.) Materials such as piano wire, which are iron-based, develop a layer of iron oxide on the surface due to low-temperature annealing, and the color changes from brown to deep blue (as shown in the photo) as the heat treatment temperature increases. Because of this blue coloration, low-temperature annealing is sometimes referred to as bluing treatment. However, in the case of stainless steel, there is not much color change even after heat treatment, so the term "bluing" does not seem appropriate as a description for heat treatment of springs in general.

Twisted spring, phosphor bronze wire, C5191, Φ1.4

Twisted spring, phosphor bronze wire, C5191, Φ1.4

Bronze wire develops "springiness" through heat treatment.

Material: Phosphor bronze wire, C5191W Wire diameter: Φ1.4 Springs are sometimes required to have properties such as non-magnetism, electrical conductivity, and corrosion resistance. It is often difficult to satisfy these properties with iron-based or stainless steel spring materials, so copper alloys are chosen. The most commonly used material for coil springs is "phosphor bronze wire." Phosphor bronze wire exhibits "springiness" only after heat treatment, so it must undergo heat treatment after forming. The heat treatment temperature is around 250 degrees and is referred to as low-temperature annealing. (For more information on phosphor bronze wire, please refer to the related links.)

Non-uniform pitch spring, nonlinear characteristic spring

Non-uniform pitch spring, nonlinear characteristic spring

To obtain a nonlinear spring constant, a coil spring with uneven pitch is effective.

To obtain a nonlinear spring constant, a coil spring with an uneven pitch, like the one in the photo, is effective. When deflection is applied to this spring, the narrower pitch section on the right side first makes contact. As a result, the apparent effective number of coils in the entire spring decreases, increasing the spring constant and significantly raising the load. The spring constant takes on a shape similar to a broken line graph. Springs with a nonlinear spring constant include not only uneven pitch springs but also conical springs. The spring constant of these springs gradually increases with increasing deflection, resulting in a curved shape. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Technical contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com Tsuruoka Spring Co., Ltd. We also support web conferencing.
