Coil spring with a wire diameter of 0.04mm [compression coil spring]

Coil spring with a wire diameter of 0.04mm [compression coil spring]

It is relatively simple and easy to mass-produce, making the price affordable and the design of the mechanism easy!

A compression coil spring is a common type of spring. Is the image of a spring that you have in mind a compression coil spring? At RIKEN Spring Industry, we have technologies that are difficult for other companies to achieve, even with general "springs." Among the many types of springs, the most commonly used is the compression coil spring. The reason for this is that its shape is relatively simple, making mass production easy and resulting in a low price, as well as facilitating the design of mechanisms. Generally, the pitch of the winding (coil) is equal, and many have an equal pitch. 【Common shapes of the seat winding part】 ■ Closed end (ground) ■ Open end (ground) ■ Tangent tail end ■ Pig tail end *For more details, please refer to the PDF document or feel free to contact us.

Spring arm SUS304-WPB Φ0.5 crushed processing

Spring arm SUS304-WPB Φ0.5 crushed processing

The crushed processing part functions as a retention for the resin coating.

The material is "spring stainless steel wire - SUS304-WPB," with a wire diameter of Φ0.5. After bending processing with a multi-forming machine, the tip is flattened (indicated by the yellow arrow). The flattening process is finished by hand using a dedicated jig. The flattened part functions as a retention stop during the subsequent resin coating process. Our company offers wire forming and bending processing services. Please feel free to consult us if you have any concerns. Our technical staff will respond carefully.

Deformation and sagging of springs: Causes and countermeasures.

Deformation and sagging of springs: Causes and countermeasures.

Introducing the causes and countermeasures for deformation and wear of springs in spring troubles!

"Settle" refers to the phenomenon where the material of a spring undergoes plastic deformation during use, resulting in a change in the dimensions of the spring, primarily caused by insufficient material strength. The adequacy of the material's strength can be calculated based on the spring's usage conditions. Countermeasures for "settle" involve changing the material to one with higher durability, increasing the wire diameter, and other specification modifications. In doing so, care is taken to select specifications that do not alter the spring's force characteristics (spring constant or load), but if there are space constraints for the spring, discussions with the customer will be necessary. If there are no issues with the strength calculations, potential causes of "settle" may include: 1) improper heat treatment after spring formation, or 2) use in an environment exceeding the heat resistance temperature. Our company addresses spring-related troubles. If you send us the deformed item, we will verify its strength and durability and propose improvement measures. Our technical staff will respond carefully, so please feel free to consult us. Tsurugaoka Spring Co., Ltd.

Causes and countermeasures for spring breakage and damage.

Causes and countermeasures for spring breakage and damage.

The clues to identifying the cause of the damage are the lifespan calculations and strength calculations.

The clues for identifying the cause of breakage are lifespan calculations and strength calculations. If a spring breaks below the calculated results, the cause of the breakage is suspected to be "stress concentration" originating from scratches or machining marks. When we examine the springs upon consultation, we often find scratches or machining marks caused during processing. In this case, reworking with attention to these scratches can lead to improvement. If the timing of the breakage aligns with the calculations, the cause of the breakage is thought to be insufficient material strength. The countermeasure for breakage in this case is to change the specifications of the spring. Specifically, this may involve changing the material to one that is more durable or increasing the wire diameter, while considering the balance to avoid altering the spring's force characteristics (spring constant, load). Our company addresses spring-related issues such as breakage and sagging. If you send us broken samples, we will propose countermeasures and, if desired, we can also produce improved prototypes. First-time customers are also welcome to consult with us without hesitation. In fact, most of the customers who consult with us have never done business with us before. We look forward to your inquiries.

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.

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.) If you have any concerns regarding springs, please feel free to contact us. Tsurugaoka Spring Co., Ltd. Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com

Counting the number of turns in a spring

Counting the number of turns in a spring

Care is needed in counting the number of turns of a spring.

I will count the number of coils in the photo of the compression spring. The number of lines = the number of circles = 5, therefore the number of coils = 5, but it is important to note that this is not the case. In the case of springs, one complete turn is counted as one coil. If you start counting from the left end, it will be one coil at the red circle. The star-marked area is still less than one coil, approximately 0.5 coils. The number of coils in this spring = 4 coils. By the way, the one coil at both ends is in contact with the adjacent coil and is called a "seat coil." The role of the seat coil is to improve stability when standing, and the seat coil itself does not function as a spring. The number of coils excluding the seat coils, which effectively work as a spring, is called the effective number of coils. This spring has an effective number of coils = 2 coils, total number of coils = 4 coils. If you have any questions or concerns about 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 conferences.
