Quality degradation due to grinding of the spring end face and heat generation, and points to note.

Quality degradation due to grinding of the spring end face and heat generation, and points to note.

[Reproduction of Private Spring Preparatory School Lecture 42] Thin wire springs, thick wire springs! An explanation of the issues of end face grinding and shot peening for both.

Even for the same type of wire springs, when the wire diameter is thick and reaches 12 millimeters or more, the manufacturing process changes as follows: ■ Material: Annealed wire ■ Process: Coiling → Cutting → Hardening → Tempering → End face grinding → Setting In some cases, shot peening may be performed after end face grinding, similar to fine wire springs. Now, let's study the common issues of both fine wire springs and thick wire springs, specifically end face grinding and shot peening. *For detailed content of the article, please refer to the PDF.

Improvement of fatigue resistance of springs by shot peening and precautions during processing.

Improvement of fatigue resistance of springs by shot peening and precautions during processing.

[Reproduction of Private Spring Preparatory School Lecture 43] Fine matte texture on airplane parts! Explanation of shot peening.

Shot peening is a processing method in which countless small steel balls are struck against the surface of springs that have completed shaping and heat treatment. As a result of this processing, the surface of the spring develops numerous indentations and becomes similar to a pearlescent pattern. The formation of these surface irregularities occurs because the steel balls collide with great force against the surface of the steel, causing that area to undergo plastic deformation. *For more detailed information, please refer to the PDF.

A comprehensive summary of the causes of wire spring damage and preventive measures.

A comprehensive summary of the causes of wire spring damage and preventive measures.

[Reproduction of Private Spring Preparatory School Lecture 45] The usable temperatures of various steel wires and JIS related to wire springs are also included in the table!

I would like to conclude the long study of spring mechanics with this session. Looking at examples of spring failures, they can be broadly categorized into breakage and deformation. Among these, the causes of breakage are mostly due to manufacturing defects and usage defects, while material defects are relatively minor. A common manufacturing defect is surface defects caused by overheating during heat treatment. In terms of usage defects, deterioration due to corrosion is likely. In the former case, shot peening is effective, while in the latter case, using stainless steel materials is effective. *For detailed content of the article, please refer to the PDF.

The Flower Preparatory School Festival: Lessons Hidden in the Songs Unraveled by the Folk Song Club

The Flower Preparatory School Festival: Lessons Hidden in the Songs Unraveled by the Folk Song Club

[Reproduction of Private Spring Preparatory School Lecture 46] Introducing songs about mainsprings, songs that encourage quality control, and songs related to painting and spring surfaces!

We decided to hold a school festival here to foster a connection between teachers and students. Titled, "Flower's Spring Prep School - School Festival." I wonder what kind of repertoire will emerge from the seriously diligent students. It's a mix of worry and excitement. First of all, the first classroom is very lively, so we've decided to come here today. Neither the president nor the students are studying today. Let's join together with the teachers and take a look at the results of our club activities. *For detailed information, please refer to the PDF. Feel free to contact us for more details.

A Satirical and Humorous Senryu of Prep School Students Seen Through Springs and Peening

A Satirical and Humorous Senryu of Prep School Students Seen Through Springs and Peening

[Reprint Private Spring Preparatory School Lecture 48] Introducing a short poem consisting of three lines of 5-7-5 syllables, primarily focusing on humor and satire!

This is the third time for the Hanano Preparatory School's cultural festival. It’s both beneficial and not beneficial, which is what makes it great. If we only talk about things that are beneficial, it becomes like a wedding table speech, and it gets boring. In that regard, our school's haiku club, which I will visit today, may not have much to offer and is quite poor, but it somehow gives off an interesting vibe. *For detailed content, you can view it in the PDF.

The relationship between spring stiffness and strength, an important point in design.

The relationship between spring stiffness and strength, an important point in design.

[Reproduction of Private Spring Preparatory School Lecture 52] Exploring specific examples of spring stiffness! We will also explain the limitations of using a spring scale.

In general, the hardness of a spring falls within a certain range. If it is too soft, it will deform under a small load, and if it is too hard, it will have low toughness and may break. Therefore, there arises a suitable hardness that is neither too hard nor too soft, which is referred to as "spring hardness." To impart this spring hardness to metals, methods such as cold working and quenching and tempering are used. Now, let’s explore specific examples of spring hardness. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*

Changes in the structure of steel due to quenching and the hardening mechanism, the influence of carbon content, and its applications.

Changes in the structure of steel due to quenching and the hardening mechanism, the influence of carbon content, and its applications.

[Reproduction of Private Spring Preparatory School Lecture 54] Changes When Hardening is Done! Explanation of Carbon Content and Hardness from Hardening.

Today, let's investigate the changes that occur when quenching. First of all, it is absolutely necessary to heat the steel to a red heat for quenching. The temperature for this is the standard quenching temperature found in the familiar JIS spring steel material table. However, this is an example for heat treatment of tensile test specimens. In reality, whether it is a leaf spring or a coil spring, there is a forming process involved, so the temperature at the end of the forming process corresponds to this temperature. Now, let's consider what significance this quenching temperature has. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*

Causes of quenching distortion and methods for suppression, effective measures using press quenching methods.

Causes of quenching distortion and methods for suppression, effective measures using press quenching methods.

[Reproduction of Private Spring Preparatory School Lecture 61] Explanation of quenching distortion! A method of quenching with less distortion is also explained.

Let's study how quenching distortion occurs. Even without special study, you can clearly understand the results just by conducting an experiment. A flat spring plate of appropriate length is ideal for the experiment. Heat this spring plate to the quenching temperature and cool it from only one side of the plate. For example, if you cool only the bottom side, it will ultimately deform so that the bottom side becomes convex. Let's look at the diagram. First, since the bottom side of the plate is sprayed with water, it will naturally shrink due to thermal contraction. In other words, since the bottom side shrinks, the plate will deform to be convex upwards. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.

Effective methods and precautions for removing quenching distortion using the press reversion method.

Effective methods and precautions for removing quenching distortion using the press reversion method.

[Reproduction of Private Spring Preparatory School Lecture 62] By using the press hardening method, it is possible to suppress the amount of distortion!

This time, let's study how to remove quenching distortion during the re-baking process. When unraveling yarn that has been knitted once and re-knitting it into something else, the yarn becomes zigzagged due to long-term setting. To remove this yarn's kink, we can use steam generated from a kettle and pass the yarn through it while pulling, which surprisingly straightens the yarn. In other words, in this case, we are straightening it by applying heat and force simultaneously. The application of this method to springs that have developed quenching distortion is known as the press re-baking method. *For more detailed information, please refer to the PDF. Feel free to contact us for more details.*
