THE PROBLEM:
In metal fabricating, machine operators are often troubled with uncontrolled loose scrap or small finished parts. The following are your costly losses:

(1) Production shut-downs.
(2) Shearing of expensive punches and dies.
(3) Damage to strip stock.
(4) Rejection of finished parts.
(5) Extra set-ups.


THE CAUSES:
Loose scrap or slugs in fabricating dies can be caused by the following factors:

(1) Excessive clearance between punch and die opening.
(2) Variation in stock thickness.
(3) Variation in stock hardness.
(4) Fabricating at high speeds.
(5) Excessive wear on the punch and die.
(6) Lubricants on stock strip cause slugs to stick to the punch.
(7) Magnetized punches.
(8) Slugs hang to punch due to burrs.
(9) Vibrations cause slugs to bounce out.


THE SOLUTION:
The BAZOOKA VACUUM SLEEVE was designed and developed as an easy method to remove loose slugs or scrap. The VACUUM SLEEVE will convert compressed air into a vacuum which is applied at the die opening. This vacuum not only prevents slugs from pulling out with the punch, but it carries them away from the die surface through the vacuum source and deposits them in a container. The advantage of the vacuum system over plain compressed air is - with vacuum you have control of the slugs or parts. With compressed air -pieces can fly back onto the working surface interfering with the die operation.

SECTIONAL VIEW OF BAZOOKA VACUUM SLEEVE illustrates how the metal scrap can pass through the sleeve without disrupting the vacuum flow or damaging the unit. Center chamber is vacuum passage and allows removal of solid material. Compressed air is forced to flow through the circular orifice creating the required vacuum. "O " Rings which seal compressed air allows liberal machining dimensions of housing for installing vacuum sleeve.
