Hi everyone, it’s Morio here! 🐾

From this post, we’re diving into one of TF’s most iconic mechanical units — the sliding mechanism! Let’s spotlight the “Slippery Slides”! ✨

🔧 Where Are the Slides in the TF Series?

First up — let’s talk about their placement.

Take a look at the front of a TF machine:
You’ll see six slide units arranged diagonally left and right.
These six slides are controlled by a single axis, all driven together by one servo motor 💡

You might wonder:

“Why not control them separately?”

Well, if we separated them, the machine would become much larger and more expensive.
But for operations like cutting or hook forming, the timing doesn’t need to vary much spring by spring.
So we proudly continue using the cam-driven single-axis sliding system inherited from VF800MFT series!

Here’s how the movement works 👇

The servo motor rotates (this is the power source!)

That rotation is transferred to the camshaft (via gears)

The cam pushes up the cam roller on the slide lever

The opposite side of the lever is connected to a link bolt, which transmits the force

The link bolt pushes the slide, converting rotary motion into precise back-and-forth linear movement!

🧩 Structure: 3 Key Components!

All six slide units share the same core structure, built from these three major components:

Part Name Function
🪵 Slide Base:  A set of the slide table and slide clamp
📏 Flat Slide: The tip holds the tool holder and processing tool
🔁 Spring & Shaft:  Spring returns the slide; shaft prevents the spring buckling!

The movement:
Forward → powered by the cam mechanism we just saw
Backward → pulled back reliably by spring tension wrapped around the shaft.
Simple, but highly reliable!

🧠 Design Insight #1: Compact Space Mastery!

Take a closer look at the front view of the TF machine shown in the thumbnail).
You’ll see — things are really packed in tight! 😳

In the center:
“Mandrel Unit” and “Pitch Mechanism”

Above:
“Torsion Attachment” for hook forming and body coiling

Below:
“Feed Unit” lined up neatly

Not to mention all the brackets and mounting elements needed to attach these units to the frame…
Even if we wanted more space for the slides — the design is always fighting a battle with tight clearances ⚔️

Fitting six sliding units with precision into this limited space…
Now that is the perfect fusion of craftsmanship and design skill!

❓Do We Really Need All Six Slides?

This is a super common question:

“Do you really need all six slides?”

The answer is…
YES!!! (no hesitation!)

For example:

🔁 When forming right-wound tension springs:

Left-upper & right-lower slides → hook forming

Left & right slides → cutting

🔁 When forming left-wound springs:

Right-upper & left-lower → hook forming

And that’s not all…
Sometimes slides support each other,
or are used for angled cuts for short end hooks
depending on the spring shape.

So yeah — removing even one slide would break the magic. Each one plays a role in the choreography!

🧑‍🏭 Where Design Meets Artistry!

Let’s wrap it up. The designer’s challenge is all about balancing these three:

💪 Maintain strength and durabili

🧠 Enable all the necessary operations

🏗️ Fit everything within extremely tight spacety

Pulling all that off?
That’s where Shinko’s design team truly shines 💫

Next time, we’ll go even deeper into the material choices, shapes, and lubrication structures that make these slides so effective!

Until then —
