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.

Compression spring SUS304-WPB Φ0.35 spring index

Compression spring SUS304-WPB Φ0.35 spring index

The "spring index," also known as D/d (debaide), is a value that serves as a guideline for the difficulty of processing.

The material used is "spring stainless steel wire SUS304-WPB." The wire with a diameter of Φ0.35 is wound into a coil with an average diameter of Φ11mm. The spring index is approximately 31, indicating that it is a spring with a high difficulty level for coiling processing. 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. It is also referred to as the spring index = D/d (Devi-D). According to JIS standards, a spring index between 4 and 22 is desirable. If the spring index is 4 or lower, the coil diameter is small and tight, making it difficult to wind; if the spring index exceeds 22, the coil diameter is large and fluffy, making it difficult to wind, which gives you that impression. This spring has a spring index exceeding 22, at 31, but how does it look? It seems to be wound quite neatly. 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 conferences.

Compression spring, phosphor bronze wire C5191W Φ0.26, return spring.

Compression spring, phosphor bronze wire C5191W Φ0.26, return spring.

Control the free length with a sensor to minimize variations in installation to maximum load.

This is a spring used for controlling the movable iron piece of an electromagnetic valve. To accurately manage the installation to maximum load, a sensor called a length measuring device is used. The length measuring device automatically measures and adjusts the free length of the spring during the coiling process. Since the variation in the spring's load is almost proportional to the variation in free length, control using this length measuring device is effective. The material used is "phosphor bronze wire, C5191W." After spring forming, the spring's properties are enhanced through heat treatment. Similar springs have been successfully made from "piano wire, SWP-A, SWP-B" and "stainless steel wire for springs, SUS304-WPB, SUS316-WPA." 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 Tsuruoka Spring Co., Ltd.

Compression spring bolt screwing spring fixation

Compression spring bolt screwing spring fixation

The spring is used by screwing it into an M10 bolt.

Material: Piano wire type A, SWP-A Wire diameter: Φ1.5 The terminal on the right side of the spring is a tightly wound 5-turn coil. The inner diameter is managed to allow for smooth screwing of an M10 bolt. The method of screwing a bolt into a tightly wound coil is sometimes used for fixing springs. By changing the wire diameter and coil inner diameter, the feel when screwing (such as smoothly like assembling a nut, or a bit tighter while applying some resistance) can be freely controlled. We will create a prototype based on your request for your evaluation. The terminal on the left side is an open-end with a pitched coil. Our company handles the manufacturing, design, and prototyping of springs. Our technical staff will respond carefully, so please feel free to consult us if you have any concerns.

Compression spring, barrel polishing, glossy finish

Compression spring, barrel polishing, glossy finish

It is finished to a shine with barrel polishing.

Material: Stainless steel wire for springs, SUS316-WPA Wire diameter: Φ4.0 After spring processing, the surface is polished to a shiny finish using barrel polishing. By finely adjusting the material, size, and polishing time of the media, a gloss like the one in the photo is achieved. We will display the actual product at the exhibition, and everyone is surprised by the level of gloss achieved just through barrel polishing. We are grateful for the trial and error on site. If you have any issues with springs, please feel free to consult us. Turuoka 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.
