Bowl Tooling Techniques - Case 2
Cylindrical Part - Diameter Greater Than Length
End Orientation - Random Diameter to Diameter, Centerline Axis Vertical
For use with flat track bowls such as:
8" - CB 151 or CB150 on Model 5 Base Unit
11" - CB 274 or CB 273 on Model 8 Base Unit
18" - CB 154 or CB 152 on Model 10 Base Unit
24" - CB 168 or CB 167 on Model 15 Base Unit
Note: Flat track bowls generally have a 7 degree positive rake to allow parts to find the corner of the track and sidewall of the bowl.
Orientation Sequence
Part completes more than one complete revolution in random orientation. The goal is to reject or convert all parts that are not diameter to diameter, centerline axis vertical. As parts approach the first wiper, rolling parts and doubles are returned to the center of the bowl. Only parts that are centerline axis vertical may pass. A pressure break reduces the build - up pressure in the bowl and diverts all parts back into the bowl when the bowl feed rate exceeds what the next operation beyond the feeder bowl can accept. At the bowl discharge point, a cover is fabricated to contain and control four or five parts to allow a smooth transition to the next operation.
