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.

Spring design - Prototyping, short delivery time

Spring design - Prototyping, short delivery time

If you provide us with the general design requirements, we will design and prototype within a short timeframe.

The twisted spring in the photo was designed and prototyped by our company. We proceeded with the design based on the following specifications you provided: 1) Coil inner diameter, 2) Load at installation to maximum angle, 3) Durability (1 million cycles) The designed spring can be prototyped in a short lead time. The spring in the photo was delivered about one week after the order was placed. We can manufacture from a quantity of one. Our company accepts the manufacturing, design, and prototyping of various springs. If you provide us with rough design conditions, we will propose the optimal specifications and produce a prototype. We understand that some may be unsure about how to specify the design conditions for the spring. Our technical staff will respond carefully, so please feel free to consult with us.

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.
