Automatic Four Jaw Pull Head (R Type)

This four jaw broach pull head assures positive and automatic connection on horizontal broaching machines. When the broach connects a coil spring moves the sleeve forward engaging and locking all four jaws around the broach shank. The broach is disengaged by contact of the sleeve against a preset stop which moves the sleeves back and unlocks the jaws. This puller can be provided with radial index key that maintains angular rotation.

The threaded RD pull head is used for pull-down broaching operations where chips fall or are washed downward by coolant onto the pull head. Special design of the head includes an umbrella top to shed falling chips and a hole in the length of the puller for chips to wash through. This head is identical in operation to the R type and can also be provided with radial index keys.

Automatic Four Jaw Pull Head (RD Type)

Precision Automatic Puller (PRD Type)

Precision long shank pullers locate in a 2 inch diameter bore. The bored hole rather than threads provide better puller accuracy in relationship of machine and fixture. The parts are produced with less runout and better concentricity. Long shank pullers can have either the R or RD style head. This type puller is used on pull down and table-up broaching machines.

Horizontal Keyway Puller

Designed primarily for keyway broaches or types of broaches using rectangular shanks this pull head can be manually or automatically operated. Proper pulling alignment is assured as the head holds the broach in position against the flat surfaces and provides a positive broach locking action. The keyway broach pull head is built in two sizes. The number (0) for broach shanks up to a maximum of .75 x .75 inch and the number (1) head for shanks with a maximum of 1.5 x 1.5 inches.

Automatic Four Jaw Long Shank Retriever head (PR Type)

Precision long shank retriever heads locate in a 2 inch diameter hole in the handler slide. This type retriever head is used on pull down and table-up broaching machines. It uses the same type of mechanism as used in the R type puller.

Detent Retriever Heads

Detent type retriever heads hold the broach cutting tools above the workpiece with a spring loaded button. The button fits into a notch ground into the retriever shank. This retriever head can be provided with radial index keys. This type of retriever does not need a trip-off bar. They are limited to lighter broach tools.

Hydraulically Actuated Pullers & Retrievers

The automatic hydraulic puller and retrievers are actuated with a cylinder rather than the mechanical cam found on conventional units. The hydraulic units are actuated through a PLC and hydraulic directional valve and are not dependent upon the movement of the slides.
