The fork head clevis (also known as a clevis fork or yoke end) is a mechanical linkage component commonly used in hydraulic or pneumatic cylinders, actuators, linkages, or mechanical systems to allow pivoting motion. It's typically manufactured from steel, stainless steel, or aluminum, and precision is important due to its role in motion transfer and load bearing.

Here’s an overview of the manufacturing process for a fork head clevis:

🔧 1. Material Selection & Preparation

• Materials: Mild steel (e.g., AISI 1018, 1045), stainless steel (304, 316), or aluminum alloys.

• Form: Usually starts with round or flat bar stock.

• The material is cut to size using band saws or CNC cutting machines.

🏗️ 2. Forging (Optional)

• For high-strength or high-volume production, the clevis may be hot forged to achieve better grain structure and strength.

• This involves heating the metal and shaping it using dies.

⚙️ 3. Machining

• CNC Milling/Turning: Used to machine the prongs (fork arms), shaft hole, and thread.

  • A lathe is used if the part has a cylindrical shank.

  • A milling machine or CNC center shapes the fork slots and flat surfaces.

• Hole Drilling: Holes are drilled for the clevis pin using a drill press or CNC drill.

• Slot Cutting: The forked ends are cut using end mills or slotting tools.

🛠️ 4. Threading

• If the clevis has a threaded rod or socket:

  • External threads (for screw-in type) are made via thread rolling or cutting.

  • Internal threads (in clevis body) are tapped using CNC or manual taps.

📏 5. Deburring and Surface Finishing

• All sharp edges and burrs are removed using deburring tools, tumblers, or grinders.

• Finishing may include:

  • Zinc plating

  • Black oxide coating

  • Powder coating

  • Anodizing (for aluminum)

🔍 6. Quality Inspection

• Dimensional checks using calipers, micrometers, and gauges.

• Hardness testing, surface finish, and thread accuracy inspections.

• Sometimes non-destructive testing (NDT) is done (e.g., dye penetrant testing) for critical components.

📦 7. Assembly and Packaging

• If part of a clevis-pin assembly, the clevis is matched with a pin and clips.

• Final product is cleaned, packed, and labeled for shipping.
