CWS contributes to labor reduction and product miniaturization - San-Etsu's Chowa Springs.

CWS contributes to labor reduction and product miniaturization - San-Etsu's Chowa Springs.

Coiled wave springs (CWS) that demonstrate excellent power in limited height spaces. They contribute to reducing work processes and miniaturizing products.

CWS refers to a compression spring formed by coiling flat wire into a continuous wave shape. 【Features】 ■ The structure receives load evenly around the coil circumference, allowing for stable and parallel "deflection" (stroke) both up and down. ■ It can handle loads significantly greater than those of conventional compression springs (compression springs), enabling a lower installation height. This contributes to the miniaturization and weight reduction of products. ■ It is more suitable for smaller strokes or static use than for larger strokes. A clear example is that by replacing multiple compression springs used in the clutch section by automobile manufacturers with a single CWS, we were able to resolve issues such as "high labor costs and time-consuming assembly" and "troublesome maintenance." Additionally, compared to disc springs or wave washers punched from sheet material, it offers better yield, lower costs for mold forming, and the ability to accommodate shape changes and special plate thicknesses, making it a noteworthy alternative to disc springs and wave washers. *Since the load is smaller compared to disc springs, it cannot be simply replaced, but it can simplify complicated assembly processes depending on the application.

Compression spring SW-CΦ3.0 cost reduction cushion spring

Compression spring SW-CΦ3.0 cost reduction cushion spring

There are various methods for cost reduction, such as using hard steel wire and eliminating grinding processes.

The material used is "hard steel wire - SW-C." Compared to piano wire, hard steel wire has lower durability but is a cost-effective and easily processed material. If the application does not involve severe repetitive loads, using hard steel wire can lead to cost reductions. If you are concerned about the durability of hard steel wire, we can calculate the lifespan of the spring for you, so please feel free to consult us. Additionally, this spring reduces costs by omitting grinding processing at both ends. In spring literature, it is stated that "grinding processing is performed when the wire diameter is Φ0.5 or more." However, depending on the application, there may be cases where omitting grinding processing does not pose any issues. Omitting grinding processing can lead to significant cost reductions, so we recommend considering this option as well. The surface treatment is "glossy nickel plating." If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Turuoka Spring Co., Ltd.

Tension Spring SUS301 - Hercules Φ2.1 Garter Spring

Tension Spring SUS301 - Hercules Φ2.1 Garter Spring

The stainless steel wire "Hercules" for high-strength springs has strength comparable to piano wire.

The material used is "high-strength spring stainless steel wire - Hercules." The wire diameter is Φ2.1. "Hercules" is a spring stainless steel wire based on SUS301. It is characterized by its high strength compared to the general-purpose SUS spring material "SUS304-WPB." Its material strength and load characteristics are said to be comparable to piano wire, making it a valuable material when you encounter difficulties in designing with stainless steel wire. This spring has been designed and prototyped by our company. We proposed the use of "Hercules" as we could not meet durability requirements with "SUS304-WPB." If you are having trouble with springs, please feel free to consult us. Our technical staff will respond carefully. Tsurugaoka Spring Co., Ltd.

Cone spring SUS304-WPB Φ0.8 taper spring

Cone spring SUS304-WPB Φ0.8 taper spring

The sensor controls the free height and suppresses load variation.

The material used is "spring stainless steel wire - SUS304WPB." To minimize load variation, coiling is performed while controlling the free height with a sensor. Only the large diameter side's seat winding is tightly wound, while the effective winding section is tapered in pitch, and both ends are not ground. Due to a large spring index (*) and a fluffy shape that is prone to deformation, care is taken during heat treatment to prevent entanglement between springs. *Spring index: The value obtained by dividing the average coil diameter by the wire diameter. It serves as a guideline for the difficulty of spring manufacturing, with JIS standards recommending a range of 4 to 22. 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 Tsuruga Spring Co., Ltd. for springs We also support web meetings.

Twisted spring SUS304-WPBΦ2.5 hinge spring

Twisted spring SUS304-WPBΦ2.5 hinge spring

To suppress the variation in moment (torque), the free angle of the arm is managed with a tolerance of ±2.5 degrees.

The material used is "spring stainless steel wire - SUS304-WPB." The wire thickness is Φ2.5. To suppress variations in the initial moment (torque), the allowable tolerance for the arm's free angle is set to "±2.5 degrees." The allowable tolerance for the arm's free angle is "±10 degrees" even under JIS standards, so "±2.5 degrees" is a quite stringent setting. A dedicated inspection jig has been manufactured, and all units are inspected and adjusted to manage the angle. If you have any issues with springs, please feel free to consult us.

Twisted spring SWP-AΦ3.5 return spring

Twisted spring SWP-AΦ3.5 return spring

Piano wire types "A" and "B" are widely used, but type "V" does not have good marketability.

The material is "Piano Wire Type A (SWP-A)," and the wire diameter is Φ3.5. Piano wire is the most commonly used material for iron-based spring materials, and there are three types: Type A, Type B, and Type V. Type A (SWP-A) and Type B (SWP-B) are used for high-end springs that require durability and precision. The difference between Type A and Type B is hardness. Type B is harder and has better resistance to deformation, but it has less elongation, making it unsuitable for forming processes like bending and drawing. For products like "twisted coil springs" with bending processes or "tension coil springs" with hook processing, it is common to use Type A due to its good formability. Type V (SWP-V) is a material specialized for valve springs, but it seems to be less commonly used because the material "SWOSC-V" for valve springs is more widely adopted. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.

The material used is "oil-tempered wire made of silicone chrome steel for spring applications, SWOSC-V." The material with a wire diameter of Φ3.8 is wound with an average coil diameter of Φ7.7mm. This is a processing task with a spring index of 2.0, which is quite challenging. The spring index is the value obtained by dividing the average coil diameter by the wire diameter, serving as a guideline for the difficulty of processing the spring. According to JIS standards, a spring index of "4 or more and 22 or less" is desirable. It is also referred to as spring index = D/d (Deviate). In the case of this spring, when the spring index is 4 or less, the coil diameter is small, making it tight and difficult to wind. Conversely, when the spring index exceeds 22, the coil diameter is large, resulting in a fluffy and unstable winding. That's the general idea. Our company processes springs with a spring index of less than 4 as well as those exceeding 22. Of course, there are limits. The limit values for the spring index vary depending on the material and wire thickness, so please consult us if you have any concerns.

Causes and Measures of Spring Deformation and Sagging

Causes and Measures of Spring Deformation and Sagging

By changing the specifications of the spring, it is possible to prevent sagging.

We have received inquiries about the issue of 'the spring's force weakening during use.' This is caused by 'sagging.' 'Sagging' is a phenomenon where the material undergoes plastic deformation during the use of the spring, resulting in a change in the dimensions of the spring, which is due to insufficient material strength. Whether the material's strength is adequate can be calculated based on the spring's usage conditions. Countermeasures for 'sagging' involve changing the material to one with higher durability, increasing the wire diameter, and other specification changes. In doing so, we select specifications to ensure that the spring's force (spring constant and load) does not change; however, if there are restrictions on the space where the spring fits, we will proceed in consultation with the customer. If there are no issues with the material strength calculations, potential causes of 'sagging' may include: 1) improper heat treatment after spring forming, or 2) use in environments exceeding the heat resistance temperature. Our company addresses issues related to sagging, deformation, and other spring troubles. If you send us samples, we will verify the strength and durability and propose improvement measures. Our technical staff will respond carefully, so please feel free to consult with us.

Twisted spring, return spring, torque spring

Twisted spring, return spring, torque spring

Please leave the design and selection of spring constants, moments, load calculations, and lifespan calculations to us.

A "torsion spring" is a type of spring that is twisted and commonly used in rotational mechanisms. It is known by various names such as torsion spring and return spring, but according to JIS standards, it is referred to as "twisted coil spring" or "torsion spring." The length and shape of the arms can vary depending on the mounting method, but at our company, we not only manufacture but also handle design and prototyping. Please leave the calculation of spring constants (spring rates), moments, loads, and lifespan to us for design, selection, and prototyping. If you provide us with rough conditions such as the desired force and mounting space, we will design and propose the optimal specifications. If you are experiencing issues with your current "torsion spring," we will redesign it. We also accommodate short lead times for prototypes. Being able to deliver urgent prototypes in a short time frame is one of the advantages we offer. We manufacture wire diameters from Φ0.15mm to Φ8mm in-house. For diameters less than Φ0.15mm or greater than Φ8mm, we can also accommodate external production. If you have any issues with torsion springs, please feel free to consult us.
