Principles, Effects, and Practical Methods of Shot Peening and Setting

Principles, Effects, and Practical Methods of Shot Peening and Setting

[Reproduction of Private Spring Preparatory School Lecture 44] Shot peening is a surface treatment! Explanation of the final process setting as well.

Shot peening is a surface treatment. It is very effective for springs made from heat-treated steel wire and springs that are formed from annealed wire and then heat-treated, but it is not as effective for springs made from cold-worked steel wire. This is because the surface of cold-worked steel wire is originally quite smooth. It is said that "a fair complexion hides seven troubles," and indeed, having a fair complexion is the first condition of beauty. Such beauties only need to wash their faces, and there is no need to apply expensive cosmetics. *For detailed content of the article, please refer to the PDF.

Exploring the relationship between fishing and springs: Research for the school festival and the fun of the Japanese language.

Exploring the relationship between fishing and springs: Research for the school festival and the fun of the Japanese language.

[Reproduction of Private Spring Preparatory School Lecture 49] Fishing rods are similar to springs in that they utilize the elasticity of bamboo, that is, the force of rebound!

Today, let's go to the fishing club's classroom. Steel can be broken down into the blade of a tool and metal. With this method, most things can be deconstructed, and their etymology can be traced. For example, the "forge" in blacksmith comes from the "ka" and "chi" of "kaneuchi" (metal hitting). Additionally, the chisel used by blacksmiths is a "cutting metal," and the hatchet used for cutting wood combines the "na" from "Kusanagi no Tsurugi" (the sword of Kusanagi) and the "ta" from "to cut." Now, how are fishing and springs connected using this method? Look forward to the research results from the fishing club. *For detailed content of the article, please refer to the PDF.

The selection and importance of metal materials for springs learned with the arrival of spring.

The selection and importance of metal materials for springs learned with the arrival of spring.

[Reproduction of Private Spring Preparatory School Lecture 50] Studying metal materials for springs! I will explain the types of steel most commonly used for springs.

There are many materials used for springs. For example, the skis that I played with in the winter mountains until recently can be thought of as board-like springs that slide on the snow, and until not long ago, they were made from wood. However, nowadays, they are made from not only wood but also materials ranging from fiberglass to metal. Let's consider why these materials have been chosen. Since skis are also springs, they must not break or deform immediately when a person, who is the load, stands on them; otherwise, they would be unusable. In other words, we want an elasticity that is suitable for the load. *For more detailed information, please refer to the PDF. For inquiries, feel free to contact us.*

The causes of burning defects and the impact of decarburization on the fatigue strength of spring steel.

The causes of burning defects and the impact of decarburization on the fatigue strength of spring steel.

[Reprint Private Spring Preparatory School Lecture 57] Burn marks can occur due to uneven quenching temperatures, uneven cooling, and the presence of scale!

Burning unevenly, that is, the cause of insufficient heating in localized areas, is often due to decarburization. Now, let's study decarburization, which is the main cause of this issue. Decarburization cannot be avoided when heating steel, not just spring steel, to high temperatures. The mechanical properties of steel are proportional to the carbon content, and fatigue strength is well proportional to hardness up to the level of spring hardness. Springs are generally used in a way that bending or torsional stresses are applied, and these stresses act so that the maximum stress occurs on the surface of the spring. *For detailed content of the article, please refer to the PDF.

Effects and countermeasures of crystal grain growth, surface oxidation, and reduction of fatigue strength in spring steel due to overheating.

Effects and countermeasures of crystal grain growth, surface oxidation, and reduction of fatigue strength in spring steel due to overheating.

[Reproduction of Private Spring Preparatory School Lecture 58] As the grain size increases, the resistance to impact decreases, and the fatigue strength also diminishes!

The damage from overheating is not just limited to decarbonization. The grain size also increases, and surface oxidation leads to more severe skin roughness. When the grain size increases, the impact value, which refers to resistance to impact, decreases, and fatigue strength also declines. Speaking of the decline in fatigue strength, surface oxidation significantly affects skin roughness. Here, please take another look at the JIS standards for spring steel materials. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*

Method for determining the organizational changes in steel due to re-annealing and the depth of quenching.

Method for determining the organizational changes in steel due to re-annealing and the depth of quenching.

[Reproduction of Private Spring Preparatory School Lecture 59] Explanation of reversion! Also explaining martensite structure and changes in structure.

Today, let's study tempering. Steel that has been fully hardened becomes martensitic, but this is extremely hard, so it must be softened to an appropriate hardness, up to the spring hardness, through tempering. The range of tempering temperatures that can achieve spring hardness is 450 to 540 degrees, and the structure will be in a tempered troostite state. Let’s explain the changes in structure due to tempering in a bit more detail. *The detailed content of the article can be viewed in the PDF. For more information, please feel free to contact us.*

Points to note during heat treatment and grinding of high-grade springs and causes of strain generation.

Points to note during heat treatment and grinding of high-grade springs and causes of strain generation.

Reproduction of Private Spring Preparatory School Lecture 60: Sometimes the spring surface may soften due to grinding heat, leading to breakage!

The stiffness of a spring is not strictly defined within a certain range. In some cases, it can be even harder. For types like leaf springs or disc springs, the spring stiffness can be increased to nearly 500 on the Brinell hardness scale. It is common to grind the surface of such springs after heat treatment, as using them with the heat-treated surface intact is very dangerous and not permissible. Now, even with such high-quality springs, there are unexpected cases of breakage, which are often due to mistakes during grinding. *For more detailed information, please refer to the PDF. For further inquiries, feel free to contact us.*

[Presentation of Materials] Case Studies on Gas Springs

[Presentation of Materials] Case Studies on Gas Springs

The longevity of gas springs has been achieved! The production line has not stopped for several years, contributing to increased productivity!

We would like to introduce a case study of the introduction of gas springs to a machinery manufacturer. In a machine used for metal processing, fine iron powder generated internally was adhering to the piston rod. Foreign substances were entering the cylinder, causing damage to the seals and leading to gas leaks. In response, we proposed an option called the "wiper ring" to prevent the iron powder adhering to the piston rod from entering the cylinder, as well as an optional "protective tube" to minimize the adhesion of iron powder to the piston rod. After implementation, the longevity of the gas springs was achieved, and the production line has not stopped for several years, contributing to improved productivity. [Results of Implementation] - Achieved longevity of gas springs - The production line has not stopped for several years, contributing to improved productivity *For more details, please refer to the PDF document or feel free to contact us.
