Tensile spring initial tension and initial stress

Tensile spring initial tension and initial stress

A little difficult to understand: "initial tension" and "initial stress"

When calculating the load of a tension spring, we consider an unfamiliar force called initial tension. Initial tension is the force that causes the coils to want to adhere to each other, and it can be determined from the wire diameter, the average coil diameter, and "initial stress." However, in the literature, it is stated that there is a certain range for the value of "initial stress," and it is troublesome as it suggests selecting an appropriate value from that range. In fact, initial tension can be adjusted by us manufacturers by winding it tightly or loosely. (We adjust the strength by changing the settings of the spring processing machine.) To put it somewhat roughly, the "range of adjustment" on the manufacturer's side is quantified as the "range of initial stress." Even if the springs appear to have the same specifications, if the manufacturer applies a strong "initial stress," it will result in a spring with strong initial tension. Initial tension and initial stress are concepts that are difficult to understand just by reading books. (For more information on initial tension, please refer to the related links.) If you have any questions, please feel free to contact us by phone or email. Tsurugaoka Spring Co., Ltd. Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com

[Parts Restoration and Reproduction Service Examples] Springs for Machine Tools

[Parts Restoration and Reproduction Service Examples] Springs for Machine Tools

Revising the mounting mechanism and designing it anew! Introducing examples of the regeneration and improvement of springs for machine tools.

We would like to introduce a case of regeneration and improvement of springs for machine tools (hooked tension springs) to a stainless steel pipe manufacturing company. We received a consultation from a customer who was troubled by the frequent breakage of tension springs in machines that had been in use for several decades, and they wanted to manufacture new ones without support from the machine manufacturer. In response, we reviewed the mounting mechanism and newly designed and manufactured springs with plate hooks and mounting brackets. We accommodated two types of machines, large and small. [Issues] <For large machines> ■ The hooks are prone to breaking, so they are secured with wire to loosen them. <For small machines> ■ The hooks are elongated. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Tension Spring

[Case Study] Tension Spring

Effectively utilize initial tension! The shape will be designed according to the order details.

A "tension spring" is a type of spring used for applications that receive tensile loads, in contrast to compression springs. Also known as a "pull spring," it is generally tightly wound to effectively utilize the initial tension and minimize space. Hooks for load-bearing are attached to both ends, and the shape is designed according to the order specifications. Please feel free to contact us with your requests. 【Examples of Use Cases】 ■ Home appliances: lid opening and closing components ■ Medical applications: electric pump components ■ Housing: mechanism components for sliding doors *For more details, please refer to the PDF document or feel free to contact us.
