Clutch suction disk for air compressor of vehicle air conditioner

Abstract

A method for manufacturing a clutch suction disk for an air compressor of a vehicle air conditioner comprises the steps of: punching a solid round cylindrical steel bar so that the steel bar to be flattened; forming a recess in a central axis of the flattened steel cylinder by cool forge; expanding a bottom of the steel bar as a disk which expands out of a lower end of the flattened steel cylinder; folding an outer side of the disk upwards so as to form an outer cylinder which encloses the flattened steel cylinder by a further cool forge; punching a bottom of the recess so that the bottom descends downwards to be lower than a bottom of the outer cylinder; and forming a round hole with a predetermined diameter at the bottom of the recess.

1 . A method for manufacturing a clutch suction disk for an air compressor of a vehicle air conditioner, comprising the steps of: 
 punching a solid round cylindrical steel bar so that the steel bar to be shorted;    forming a recess in an axial central portion of the shortened steel cylinder by cool forge;    expanding a bottom of the steel bar as a disk which expands out of a lower end of the flattened steel cylinder;    folding an outer side of the disk upwards to form an outer cylinder which encloses the flattened steel cylinder by a further cool-forge process;    punching a bottom of the recess so that the bottom descends downwards to be lower than a bottom of the outer cylinder; and    forming a round hole with a predetermined diameter; at the bottom of the recess.    
   
   
       2 . An integral formed clutch suction disk of an air compressor of a vehicle air conditioner comprising: 
 a steel cylinder having a recess through a central axis thereof;    a disk expanding from a bottom of the steel bar as a disk which is out of a lower end of the flattened steel cylinder; an outer side of the disk being folded upwards so as to form an outer cylinder which encloses the steel cylinder;    wherein a bottom of the recess is descended downwards to be lower than a bottom of the outer cylinder; and a round hole with a predetermined diameter is formed at the bottom of the recess.
