A PROCESS FOR PRODUCING VARIABLE DISPLACEMENT COMPRESSOR PISTONS HAVING HOLLOW PISTON BODIES AND INTEGRAL ACTUATOR RODS |
摘要 |
<p>Variable displacement pistons are produced wherein hollow piston bodies are integrally formed with associated actuator arms to ensure proper alignment of the bodies and rods. The process utilizes a two-axis press to first form a pair of actuator arms by working a blank of metallic material along a first axis between opposing members of a die assembly. With the die assembly still closed after formation of the actuator arms, a pair of hollow piston bodies are formed by extruding the remainder of the blank of metallic material along a second axis. The hollow piston bodies are axially aligned and integrally formed with respective ones of the actuator arms. A piston head is welded to the end of each hollow piston body which is then machined. By separating the actuator arms from one another, a pair of variable displacement compressor pistons having hollow piston bodies axially aligned and integrally formed with respective actuator arms are thus formed.</p> |
