Abstract

PURPOSE: To mass produce a hanger ear for holding the trolley cable, by extruding aluminum into a rod of a sectional shape with the identical shape of the extrusion die plate hole, by cutting this aluminum rod into a specified length, and by providing a groove and a bolt hole in this segmental aluminum rod.
CONSTITUTION: The die plate is provided with a hole of an irregular shape comprising from upside to downside the projection 1a, the hollow 1b, the flat part 1c and the clamp 1d in this order; aluminum is extruded through this die plate and an aluminum rod of a sectional shape with the identical shape of the die hole is prepared. This aluminum rod is cut into a specified length; a vertical groove 2 is formed in the middle of the projection 1a of each segment out of the aluminum rod, and a bolt hole 3 is bored in the flat part 3c. Thus prepared two segments are placed facing each other, and the bottom ring of the hanger bar B is held in the hollow 1b, the bottom neck of the hanger bar B is held in the groove 2, and the trolley cable T is held in the clamp 1d; these are tightly clamped by the bolt 4 so as to assemble the hanger ear segments 1 obtained by the extrusion work into the exact shape.
