The Scell-it E-410NV is a two-hand operated nuttool designed in France, suitable for setting rivet nuts. This manual provides essential information regarding its function, technical specifications, usage, and maintenance.
Function Description
The E-410NV is a manual tool used for installing rivet nuts, also known as threaded inserts. It operates by pulling the rivet nut mandrel, causing the body of the rivet nut to deform and create a secure thread in a material. This tool is designed for ease of use with its two-hand operation, providing leverage for efficient installation. It is capable of handling a range of rivet nut sizes, from minimum M4 to maximum M10. The tool's design emphasizes durability and user-friendliness, making it suitable for various applications where threaded inserts are required.
Important Technical Specifications
- Capacities: The tool is compatible with rivet nuts ranging from M4 to M10. This broad range allows for versatility across different project requirements.
- Length: The overall length of the tool is 485 mm, providing sufficient leverage for comfortable operation.
- Weight: Weighing 1.1 kg, the E-410NV is relatively lightweight for a two-hand operated tool, reducing user fatigue during prolonged use.
- Levers: The levers are constructed from steel, ensuring strength and durability for repeated use.
- Handle Material: The handles are made from ABS, a common thermoplastic polymer known for its impact resistance and toughness, providing a comfortable and secure grip.
- Design Origin: Designed in France by Scell-it, indicating a focus on quality and engineering.
Usage Features
The operation of the E-410NV involves a straightforward three-step process:
- Preparation: Insert the rivet nut onto the puller of the tool. The tool is then positioned over the pre-drilled hole in the workpiece.
- Setting: The user grips both handles and squeezes them together. This action pulls the mandrel, causing the rivet nut to deform and securely fasten to the material.
- Release: After the rivet nut is set, the handles are released, and the tool is withdrawn from the newly installed rivet nut.
Setting Adjustment (Finish Setting):
The tool allows for adjustment of the setting depth to ensure proper installation of the rivet nut.
- Correctly Set (YES): A properly set rivet nut will have its body fully expanded and securely fastened to the material without excessive deformation or stripping of the threads. This is indicated by a firm, flush installation.
- Not Fully Set (NO): If the rivet nut is not fully set, it means the body has not expanded enough to create a secure hold. This can result in a loose or wobbly installation. To correct this, the setting mechanism needs to be adjusted to pull the mandrel further.
- Over-Set (NO): Over-setting occurs when the mandrel is pulled too tightly, potentially stripping the thread of the rivet nut or damaging the tool's mandrel. This can also lead to excessive deformation of the rivet nut body, compromising its integrity. If this happens, the setting mechanism needs to be adjusted to reduce the pull.
The adjustment mechanism involves rotating a component on the tool's head.
- Steps 1-3 (Adjustment): The diagram shows a sequence of rotating a knurled ring on the tool's head. This ring likely controls the stroke length of the puller, allowing the user to fine-tune how much the rivet nut is compressed. Rotating it in one direction (e.g., clockwise) might increase the pull, while rotating it in the other (e.g., counter-clockwise) might decrease it. The goal is to achieve a "YES" setting, where the rivet nut is firmly installed without being under or over-tightened.
Maintenance Features
The manual provides instructions for the uninstallation and reinstallation of the puller, which is a key maintenance procedure for this type of tool. This process is crucial for replacing worn-out pullers or changing to a different size puller to match the rivet nut being installed.
Uninstallation of Puller:
- Screw Off Anvil and Locknut: The first step involves unscrewing the anvil and the locknut located at the front of the tool's head. These components secure the puller in place.
- Pull Out the Puller: Once the anvil and locknut are removed, the puller can be extracted from the tool. The diagram shows the puller being pulled out from the front of the tool.
Installation of Puller:
- Insert the Puller From the Tool Forward: The new or desired puller is inserted into the tool from the front, ensuring it is correctly aligned with the internal mechanism.
- Screw On Locknut Then Anvil: After the puller is in place, the locknut is screwed back on, followed by the anvil. These components secure the puller and are essential for the tool's proper function.
Important Note: The manual explicitly states, "Note: anvil size and puller size shall be the same." This highlights a critical aspect of maintenance and operation: the anvil and puller must be matched to the specific size of the rivet nut being installed. Using mismatched components can lead to improper installation, damage to the rivet nut, or damage to the tool itself.
Overall, the Scell-it E-410NV is a robust and user-friendly manual rivet nut setting tool, designed for efficiency and durability, with clear instructions for both operation and essential maintenance.
