ALCOA RECOIL PDF

Sturdy reusable container Recommended drill size on the label Spark plug kits have pilot nose taps for accurate self alignment eliminating the need for drilling. Manual Tool The standard Recoil insert installation tool is the most practical and simple to use for general applications. This tool may be used to install 1D through to 3D length inserts but care must be taken to ensure that the adjustable collar is correctly set to suit the particular type and length of the Recoil insert. If the collar is incorrectly set, the insert will not drive properly and the tool may slip off the tang as the insert enters the hole.

Sturdy reusable container Recommended drill size on the label Spark plug kits have pilot nose taps for accurate self alignment eliminating the need for drilling. Manual Tool The standard Recoil insert installation tool is the most practical and simple to use for general applications. This tool may be used to install 1D through to 3D length inserts but care must be taken to ensure that the adjustable collar is correctly set to suit the particular type and length of the Recoil insert.

If the collar is incorrectly set, the insert will not drive properly and the tool may slip off the tang as the insert enters the hole. For general use, the collar should be adjusted such that the insert tang is positioned mid-way along the slot with the insert coils compressed.

This will allow the insert free movement to suit the parent material thread pitch during installation. If the installation tool is used to break off the tang, then it must be lifted clear of the insert following installation and replaced into the insert at 90 degrees to its drive position.

This ensures that the tool is correctly placed on the insert tang. Tap the tool sharply downward to produce a clean tang break.

Note: The manual installation tool is not recommended for the installation of locking inserts. Note: Recoil manual tools are not recommended for use with other brands of wire thread inserts. Semi Production "Prewinder" Type Installation Tool This type of tool is ideal for installing inserts in small production runs or in areas where compressed air or electricity are not available and offers a quicker alternative to the simple hand installation tool.

The tool is suitable for use when installing free running and locking inserts. Slotted Mandrel Type The slotted mandrel tool allows the rapid installation of inserts, however it is best suited to free running inserts.

This tool eliminates the need to wind the mandrel into and out of the insert offering quicker installation cycles. Threaded Mandrel Type The threaded mandrel type is suitable for the installation of free running and locking inserts.

The mandrel is wound into the insert which is then wound into the tapped hole. The mandrel is removed by turning the crank in a counter clockwise direction, leaving the insert in place. Note: The threaded mandrel type installation tool is recommended for installing locking inserts.

Recoil Tang Break Off Tools Tang breakoff tools are available in hand, semi automatic spring type and pneumatic. The Spring Loaded and Pneumatic tang break tools are recommended for removal of tangs in production applications. For large diameter fine thread inserts, ie M Recoil powered installation tools may be supplied for use with either a compressed air supply or via a stabilized low voltage power supply to suit your particular requirements.

Both equipment types offer significant productivity gains for high volume insert use. Rugged and versatile air motor. May be used with captive strip feed or bulk insert insertion. Standard speed rpm. Auto reverse on release of trigger. The complete pneumatic insert installation tool comprises of 3 components:- 1 Air motor with single lever control to install and retract.

Recoil offer two different types of air motors, the series and the NR-HL series. For further details please contact us. Spring Loaded Tang Break Tool Spring loaded Tang Break tools offer effective removals of insert tangs and are suited from medium to large insert usage.

This tool is a spring loaded punch and when the tool is pushed down, the pin punches downward breaking off the tang. This tool works on the same basis as the spring loaded tool, except pin punches downward when an arc cylinder is actuated by the valve.

They have a larger diameter, but the same pitch as a standard tap in order to accommodate the wire insert. Spiral point and spiral flute machine taps are also available for volume production purposes.

For all sparkplug applications, pilot nose taps are recommended and are available for common metric thread sizes. The Recoil thread insert when installed into a correctly tapped hole will provide the applicable internal thread tolerance for the installed bolt. Note: Tapped hole size can be significantly affected by variations in drill size, parent material, or lubricant so in close tolerance applications some testing for an optimum combination is recommended.

Thread Class Unified Thread Class In the unified thread system, the minimum pitch diameter for a 2B hole medium fit or 3B hole close fit are the same, while the maximum pitch diameter is greater on the 2B hole medium fit. Recoil taps for unified threads are made to a 3B hole close fit tolerance.

Metric Thread Class In the metric thread system the minimum pitch diameter for a 5H hole medium fit or 4H5H hole close fit are the same, while the maximum pitch diameter is greater on the 5H hole medium fit.

Recoil taps for metric threads are made to 4H5H hole close fit tolerance. Tap Type and Applications The most commonly used type of Recoil taps are defined together with their typical applications.

The Taper, Intermediate and Bottoming are short machine taps suitable for hand tapping , while the Spiral Point and Spiral Flute are used in production applications. The quality of the tapped hole which accommodates the insert, determines the finished size and hole quality after the insert has been installed. If the finished tapped hole gauges satisfactorily, the installed insert will be within the thread tolerance. Gauge handle and all gauge nibs are marked with the extreme product limits for particular size and class of fit.

Where precision is required, 3B gauges should be used. When using locking inserts, 3B gauges should be used as close precision is required. Fits and Tolerances Recoil gauges are supplied for two different classes of fit tolerances. These are close and medium tolerance. Gauges are used to check the pitch diameter of the tapped hole, the No Go end of the gauge checks the pitch diameter is not too large and the Go end checks the pitch diameter is not too small.

Locking Insert.
