Split Sleeve Tooling - Puller Guns & Power Paks

Split Sleeve Process Description,

Split-sleeve coldworking was developed in the early 1970's as a way to improve joint fatigue performance by expanding or compressing the material around the fastener hole. In the split-sleeve process, this is accomplished by inserting a mandrel that has been prefitted with a disposable sleeve, through a fastener hole, and pulling the mandrel back through the sleeve. The internal surface of the sleeve is pre-lubricated with a special dry lubricant, protecting the mandrel from excessive wear, and reducing the amount of force required to pull the mandrel.

For a further description of this process, please call our technical sales department, or download Engineering Handout WCI-EH-9201.

Puller Guns

Puller guns are hydraulically powered units used to pull a mandrel through the workpiece. The majority of holes under 9/16" (14.3 mm) diameter in aluminum can be coldworked with the smallest gun, the WCI-1700. Larger holes require bigger guns as pull force is proportional to hole size, material strength, and stackup thickness.

Restricted Access Problems     

Certain situations may occur whereby frontside and/or lateral clearance is insufficient for a regular puller unit. WCI manufactures a complete selection of standard equipment to help solve these problems, or will work with you on your unique restricted access situations.

Restricted Access Solutions - Offset Adapters     

Offset adapters are fitted to standard puller guns to increase frontside and lateral clearance. West Coast Industries offers two offset adapters, the 1700-OA for the 1700 puller, and the 1800-OA for the 1800 puller.

Restricted Access Solutions - Hydraulic Offsets

1700-HO

The 1700-HO is one of the smallest of the hydraulic offsets offered by West Coast Industries, and is ideal for very tight restricted access situations, where the 3.8" (9.7 cm) jaw height can be invaluable.

                  

1750-HO

The 1750-HO is a hydraulically operated puller, used in tight, restricted access situations to coldwork holes between 7/16 and 51/64" (11.1 - 20.2 mm).

                  

1800-HO

The compact dimensions of the 1800-HO, hydraulically operated puller, make it ideal for extremely tight situations where a large diameter hole must be coldworked.

-35 3.5 (8.9) 12.7 (32.3) 6.9 (17.5)

1600-HO

Packaged with compact external dimensions and light weight, the 1600-HO is useful in restricted access situations. The return spring results in simplicity of construction and a reduction of external dimensions.

                  

WCI-MP

The WCI-MP is a hydraulically actuated puller designed to reach areas not otherwise accessible. The MP uses special MP mandrels.

WCI-MHP

The WCI-MHP, Miniature Hand Puller, is used in severely restricted access areas. Like the WCI-HP-20, it is operated with a ratcheting wrench. The MHP is designed to coldwork 1/2" stackups, up to 5/16" diameter. It uses special MHP mandrels.

      

Hand Puller

The WCI-HP-20 is a manually operated wrench-type puller for use where access is very limited or only a few holes need to be coldworked. It can pull stackups to 2", and uses standard 1700 series mandrels, jaws, and nosecaps, or extension nosecaps and mandrels. The WCI-HP-20 includes a storage box and ratcheting wrench.

Power Pak Units     

All puller guns, except the WCI-HP-20 hand puller, require a hydraulic power supply to operate. WCI offers two air powered units, the WCI-20, a small unit meant for low volume coldworking, and the WCIS-10000 units, offering greater speed and intended for higher volume applications. All power units, except the hand powered MP-392, are available with an optional automatic lubrication system for mandrel lubrication when using the split mandrel process.

WCIS-H10000

The WCIS-H10000 is a factory-oriented hydraulic power supply, able to pull a mandrel through the workpiece in less than one second. It is powered by a 2.2 HP air driven intensifier piston pump. The the H10000 produces 10,000 psi (691 Bar).

WCI-20

The WCI-20 is a small, economical unit designed for applications where only a few holes need to be coldworked, such as aircraft repair shops, or where mobility is a prime requirement, such as special access situations where a larger power pak would be cumbersome.

WCI-MP-392

The MP-392 is a manually operated hand pump, providing the necessary hydraulic pressure to power any of the WCI pullers.

Hose Assemblies

The hose assembly connects the puller gun to the power-pak. It consists of three hoses: a high pressure hydraulic hose and two low pressure air lines. Assemblies are available in standard lengths of 10', 15', and 20', (3, 4.5 and 6 m) or other lengths by special order. All necessary fittings are included.
