Compression spring SUS316-WPAΦ0.45 switch spring

Compression spring SUS316-WPAΦ0.45 switch spring

SUS316-WPA is a highly corrosion-resistant material used for springs in locations exposed to seawater and in food factories.

The material used is "spring stainless steel wire - SUS316-WPA." Compared to the general-purpose SUS spring material "SUS304-WPB," it has higher corrosion resistance and is often used for springs in locations exposed to seawater, food factories, and pharmaceutical factories. Additionally, while "SUS304-WPB" is weakly magnetic, "SUS316-WPA" is almost non-magnetic. This spring is used in the switch part of a certain interior product. The mounting load in the assembled state and the maximum load when the button is pressed are measured and managed using a spring load testing machine. The shipping inspector checks each lot and attaches a material certificate (mill sheet) and inspection report before shipment. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Tsurugaoka Spring Co., Ltd. Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com We also support web conferencing.

Snap spring piano wire SWP-AΦ0.5 flatness control

Snap spring piano wire SWP-AΦ0.5 flatness control

Since flatness is important, we manufacture dedicated jigs for inspection and management.

The material used is "Piano Wire Type A, SWP-A." This spring is processed by a multi-forming machine, involving winding and bending. Since the flatness of the product is important (to avoid rattling when placed on a flat surface), we use dedicated jigs for inspection and management. After forming the spring, heat treatment (bluing) is performed, and blackening treatment is applied for rust prevention. We also have experience with similar springs made from "stainless steel wire for springs" and "bronze wire." If you have any issues with springs or forming, please feel free to consult us. Our technical staff will respond carefully. Tsurugaoka Spring Co., Ltd. Technical Contact: Ujie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com We also support web meetings.

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.

Tension Spring SWP-AΦ2.3 Clutch Spring

Tension Spring SWP-AΦ2.3 Clutch Spring

The tool is smoothly wrapped and processed to prevent scratches and scuff marks.

The material used is "Piano Wire Type A, SWP-A," with a wire diameter of Φ2.3. The shape of the hooks at both ends is "semi-round hooks." The hooks are formed using a multi-forming machine, which includes the hook processing. Since tension springs have the characteristic of concentrating stress (load) at the hook part, the processing tools are smoothly wrapped to prevent scratches and marks. After spring forming, heat treatment (low-temperature annealing) is applied to remove processing strain. The surface treatment is "trivalent chromate + baking." Springs of the same shape have also been successfully made from spring stainless steel wire, SUS304-WPB, SUS316-WPA, and Herculite. Our company handles the manufacturing, design, and prototyping of tension springs. Please feel free to consult us if you have any concerns.

Compression spring valve spring SWOSC-VΦ4.2

Compression spring valve spring SWOSC-VΦ4.2

There are "spring type" and "valve spring type" in the iron-based spring material "oil-tempered wire."

The material used is "Silicon Chrome Steel Oil Tempered Wire for Valve Springs (SWOSC-V)." The wire thickness is Φ4.2. There are two types of oil-tempered wire for iron-based spring materials: "spring use" and "valve spring use." While the base material for "spring use" is hard steel wire, "valve spring use" employs piano wire as the base material, with strict quality standards established due to impurities in the steel and surface conditions. Thus, "valve spring use" is considered a higher-grade material. "SWOSC-V" is the most durable material among spring materials conforming to JIS standards. It is chosen when the durability of the iron-based spring material "piano wire" does not meet requirements. However, it is a material that is easily affected by hydrogen embrittlement, so plating treatment is not allowed. Therefore, the valve spring in the photo has been treated with electrodeposition coating as a rust prevention measure. If you have any concerns regarding springs, please feel free to consult us. Our technical staff will respond carefully. Tsurugaoka Spring Co., Ltd. for springs Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com We also support web meetings.

Compression spring SUS304-WPBΦ1.2 pump spring

Compression spring SUS304-WPBΦ1.2 pump spring

It is a specification for press-fitting a fixing shaft into the seat roll section.

Material: Spring stainless steel wire - SUS304-WPB Wire diameter: Φ1.2 The ends of a compression spring are called "seat coils." Typically, seat coils consist of one turn each, with the ends attached to the adjacent coils. (This is referred to as a closed end.) This spring has three turns of seat coil on one side only. To press-fit a fixing shaft into this seat coil section, the inner diameter tolerance of the seat coil section is managed at +0.2, -0. The opposite side (the front side) has a standard one-turn seat coil. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.

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 open end

Compression spring open end

The end shapes of compression springs are "closed end" and "open end."

The typical type is a closed end, where the tip of the coil at the end is in contact with the next coil. This single turn at the end is called a "seat coil" (zamaki). The seat coil serves to improve the stability of the spring when it is upright, but it does not have any functional role as a spring. The turns that function as a spring are those excluding the seat coil, and the number of turns that effectively function as a spring is referred to as the effective number of turns. The spring in the photo is an atypical "open end." The tip of the coil at the end is not in contact with the next coil, creating a gap (indicated by the arrow). The seat coils at both ends are less than one turn, resulting in fewer seat coils compared to a closed end. The reason for deliberately adopting a non-typical open end is mainly in the following cases: 1) When you do not want to change the spring constant (want to keep the effective number of turns fixed), and 2) When you want to keep the height at which the spring is in contact low (want to reduce the total number of turns). While reducing the seat coils may worsen the stability of the spring, it allows you to maintain the spring constant while keeping the contact height low.

Tension spring with a narrowed round hook

Tension spring with a narrowed round hook

Are you having trouble with broken springs in your production equipment or lines?

The hook shape in the photo is called a "shutter round hook." The hook is formed with a wire diameter thicker than the body, and it is incorporated into the body with a stop-off process. This hook shape is particularly strong against breakage and deformation. This spring is a breakage countermeasure product designed and prototyped by our company at the request of a customer. We received a consultation regarding "springs breaking in production equipment and lines" and redesigned it with improved specifications. We have enhanced durability without changing the force applied (load) when pulled. Our company addresses spring troubles such as breakage and sagging. If you send us broken samples, we will propose countermeasures and, if desired, we can also produce improved prototypes. Our technical staff will respond carefully, so please feel free to consult with us. Tsurugaoka Spring Co., Ltd.
