Twisted spring SWP-AΦ6.0 clutch return spring

Twisted spring SWP-AΦ6.0 clutch return spring

To reduce the variation in moment, the initial tension is processed to be slightly weaker.

The material used is "Piano Wire Type A - SWP-A." To minimize the variation in moment (torque), the initial tension is processed as weakly as possible. Initial tension refers to the force that causes the wires to try to adhere to each other, and if this initial tension is too strong, it can affect the moment of the torsion coil spring. Conversely, in the case of tension springs, this initial tension is utilized to manage the load. 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 Hatsujo Co., Ltd. for springs We also support web meetings.

Cone spring SWP-BΦ2.9 taper spring

Cone spring SWP-BΦ2.9 taper spring

One turn at both ends of a compression spring is called a "seat coil," and the terminology varies depending on the shape (closed end, open end, etc.).

The material used is "Piano Wire B Type - SWP-B." One coil at both ends of a compression spring is called a "seat coil." To ensure stability when the spring is upright, the tip of the "seat coil" is usually made to closely contact the adjacent coil. This shape is referred to as "closed end." If the tip of the "seat coil" is separated from the adjacent coil, it is called "open end," but this is not very common, and unless specifically instructed, it will be manufactured as a "closed end." The springs in the photo also have "closed ends" at both terminals. It is a bit difficult to see, but the seat coil at the front has a tapered shape that becomes smaller. The surface treatment is "electroless nickel plating." If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.

Tension Spring Special Hook SWP-A2.0

Tension Spring Special Hook SWP-A2.0

We can accommodate hooks with special shapes that are not specified in JIS standards.

The material is "Piano Wire Type A, SWP-A," and the wire thickness is Φ2.0. The hook shape of this spring is a special one not specified by JIS standards. It is narrowed inward once, and the hook is raised from the center of the body. Due to the difficulty of handling it with a multi-forming machine, the hook is shaped by hand. After shaping, heat treatment (low-temperature annealing) is applied to remove processing strain, and it is coated with zinc plating for rust prevention. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.

Twisted spring SWP-AΦ1.2 return spring

Twisted spring SWP-AΦ1.2 return spring

We manufacture dedicated positioning jigs and other tools to maintain and manage dimensional accuracy.

The material used is "Piano Wire Type A - SWP-A." According to customer requests, the positional relationship between the larger and smaller coils is important. However, it was quite difficult to measure the dimensions accurately with calipers or height gauges. After discussions, we created a positioning jig using two pin gauges of different sizes. By assembling the springs one by one into the jig, we were able to measure and manage the dimensions. There are various requests from customers regarding the dimensions and shapes of the springs. In some cases, we manufacture dedicated jigs like this one to maintain and manage dimensional accuracy. 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.

Tension Spring SWP-BΦ5.0 Left-Handed

Tension Spring SWP-BΦ5.0 Left-Handed

It is a rare case where a "left-handed" spring is used in a tension spring.

The material used is "Piano Wire Type B, SWP-B," with a wire diameter of Φ5.0. The body part is wound using a heart gold type winding machine, while the hook part is shaped by hand. After heat treatment, an electroless nickel plating is applied as a rust prevention treatment. The winding direction of this spring is "left-handed." To determine the winding direction, if you stand the spring upright and look at it from the side, if the coil material is winding upwards to the right, it is right-handed; if it is winding upwards to the left, it is left-handed (according to JIS standards). For compression springs and tension springs, unless otherwise specified, they will be manufactured as right-handed. In particular, it is very rare for left-handed winding to be adopted for tension springs, and I would like to ask our customers someday why this spring is left-handed. Our company handles the manufacturing, design, and prototyping of tension springs. Please feel free to consult us if you have any concerns. Tsuruoka Spring Co., Ltd.

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 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.
