Spring News April Issue" includes trivia about springs: "About Spring Index.

Spring News April Issue" includes trivia about springs: "About Spring Index.

April issue of the Spring News delivered every month! We introduce the spring index (D/d).

The spring index (D/d) is the value of the coil's average diameter divided by the wire diameter. While there are other factors that affect ease of manufacturing, it is generally considered that this value should be between 4 and 20, with 7 to 13 being particularly suitable for spring production. Although a spring index of 4 to 20 is desirable, it is not an absolute requirement to stay within this range. However, producing springs outside of this range can be very difficult or even impossible, so it is advisable to keep it within this range as much as possible. Please leave the design, estimation, and production of various springs to us. *For more details, please refer to the PDF document or feel free to contact us.*

Spring News June Issue" includes a trivia about springs: "What is the effective number of coils?

Spring News June Issue" includes a trivia about springs: "What is the effective number of coils?

The June issue of the Spring News delivered every month! It is considered good to have a valid number of volumes of 3 or more.

The effective number of coils refers to the portion of the coil that acts as a spring, calculated by subtracting the number of end coils from the total number of coils in a compression spring. Generally, end coils are often one coil each at both ends, so in that case, the effective number of coils is total coils minus 2. If the first coil and the last coil do not contact the next (previous) coil, and the ground portion is 3/4 of a coil, the effective number of coils becomes total coils minus 1.5. It is considered good practice to have an effective number of coils of 3 or more. For tension springs, the total number of coils equals the effective number of coils (excluding the hook sections). Please leave the design, estimation, and production of various springs to us. *For more details, please refer to the PDF materials or feel free to contact us.*

The development of the spring industry in the early Taisho period and technological innovation through the introduction of testing machines.

The development of the spring industry in the early Taisho period and technological innovation through the introduction of testing machines.

[Reproduction of Private Spring Preparatory School Lecture 6] Standards and specifications for steel materials and springs have been established! The spring industry made great strides in the early Taisho period.

In the previous discussion, we talked about how the spring manufacturing industry modernized in the late Meiji period, and how other related industries made remarkable progress. Now, let's study the development process of the early Taisho period. In the late Meiji period, there were printing machine companies that were winding springs, and there is a story that when spring manufacturers went to take orders, they boasted that they could also wind springs. This was because the manufacturing of springs at that time was a closely guarded secret, and even if something was considered good, there were no methods to investigate it. *For detailed content of the article, please refer to the PDF.

The development of the automobile and aircraft industries during the Showa period and the role of the spring industry.

[Reproduction of Private Spring Preparatory School Lecture 9] Explaining the transition of the automotive and aerospace industries! Also discusses war and the spring industry.

Last time, we got sidetracked with the discussion about the new type of Katasa testing machine, but we are finally entering the history of springs in the Showa period. Since the Showa period is quite recent, I believe many of you are already familiar with various aspects, so let's study quickly. The spring industry, having inherited the developments of the late Taisho period, continued to thrive, and undoubtedly, the contributions of automobiles and airplanes were significant, so this time we will focus our study on this topic. As mentioned before, the entry of American automobile manufacturing into Japan from the late Taisho to the early Showa period stimulated the existing three companies in Japan to start full-scale production. *For detailed content of the article, please refer to the PDF.

Establishment of Standards and Changes in Steel Materials in the Spring Industry during the Showa Period

Establishment of Standards and Changes in Steel Materials in the Spring Industry during the Showa Period

[Reissue Private Spring Preparatory School Lecture 10] About the spring industry during the Showa period! Establishment of various standards and specifications, from JES to JIS.

Last time, we studied the automotive and aircraft industries that form the background of the spring industry during the Showa period. Continuing from that, this time we will have a lesson on the spring industry during the Showa period. One characteristic of the Showa period that must be addressed is the establishment of various standards and specifications. The establishment of such standards can be seen as evidence of the advancement of research into industrial products. For example, regarding the Japanese National Railways, specifications for carbon steel materials for vehicle springs, wire springs for cushions, and wire and plates of phosphor bronze for springs were established in 1928. In 1930, specifications for hard-drawn steel wire for springs were established, followed by specifications for leaf springs and steel wire springs in the following year. *For detailed content of the article, you can view it in the PDF.

The evolution of spring technology and heat treatment methods during the Showa period and their historical background.

The evolution of spring technology and heat treatment methods during the Showa period and their historical background.

[Reissue Private Spring Preparatory School Lecture 11] Explanation of single and double quenching methods! Discussion of new materials and technologies as well.

Last time, we talked about JES and JIS, but this time let's trace the technical history of the Showa era. I gave it a confusing title like "one-stage or two-stage," but in fact, since the late Taisho period, the method of hardening spring plates has been a significant issue for the National Railways, so let me introduce the background. The term "one-stage hardening," which was used at that time (the Taisho period), refers to what we now call "austenitizing hardening," while "two-stage hardening" refers to the process of hardening and tempering. In this regard, the terminology used in heat treatment was incorrect, so although I wrote "one-stage" and "two-stage" in the title for this preparatory school, I will use the correct terms: "austenitizing hardening" for the former and "hardening and tempering" for the latter. *You can view the detailed content of the article in the PDF.

The influence of dynamic stress and fatigue failure in automobile springs and its relationship with road conditions.

The influence of dynamic stress and fatigue failure in automobile springs and its relationship with road conditions.

[Reproduction of Private Spring Preparatory School Lecture 14] Characteristics of stress on springs! Used under significantly larger static and dynamic stresses.

In the last session, we started with a method for cutting wire by hand and studied fatigue testing methods, but we will continue with the lessons. As you know, springs are used in a very different way compared to general mechanical components. This is evident at a glance, as springs are often significantly bent or undergo intense stretching and contracting movements. The fact that springs are used in this manner means that they are subjected to much larger static and dynamic stresses compared to the design stresses of general mechanical components. *For detailed content of the article, you can view it in the PDF. Please feel free to contact us for more information.*

Observation of fracture surfaces and understanding of the safety zone in fatigue testing of metallic materials.

Observation of fracture surfaces and understanding of the safety zone in fatigue testing of metallic materials.

[Reproduction of Private Spring Preparatory School Lecture 17] Metals also change when they are fatigued! An explanation of how the results of fatigue tests are organized and utilized in design.

The fracture surface of the fatigue test specimen, like that of an actual fatigue fracture, exhibits both smooth and rough surfaces. The difference is that, in many cases, the smooth surface does not show the shell-like patterns resembling tree rings. This is because the testing machine applies a constant repeated stress, preventing the progression of cracks from exhibiting a step-like pattern. The shell-like patterns that form on the fatigue fracture surface of automotive springs occur due to variations in the weight of the load or changes in road conditions, which cause fluctuations in the repeated stress. Additionally, there are instances where the smooth fracture surface of the test specimen appears discolored purple; this is due to temper colors resulting from frictional heat generated by the rubbing of the crack surfaces. *For more detailed information, please refer to the PDF. Feel free to contact us for further inquiries.*
