Peening machine

An apparatus, comprising;

• a rotary peening head mounted on a stationary surface;
• a worktable with a part thereon moving parallel to the stationary surface;
• the rotary peening head positioned at 45° angle on the stationary surface from the axis of the worktable direction of travel;
• and
• a fan shaped shot path directed across the part at a 45° angle as the part moves beneath the stationary surface on the worktable.

A method for shot peening, comprising:

• directing a fan shaped stream of shot from a rotary shot peening head mounted on a stationary surface at a 45 degree angle across a part on a worktable;
• moving the worktable past the penning head in a direction that maintains the 45 degree angle in the direction of the worktable travel and the worktable and the stationary surface are spaced apart from each other a predetermined distance and also parallel to one another at all times during the travel of the worktable;
• collecting the used shot in a pit below the travel of the worktable;
• recycling the shot collected in the pit back to the rotary shot peening head;
• collecting the dust created by the shot peening in a hopper;
• and
• utilizing the hopper to dispose of the dust in an environmentally safe manner.

A shot peening machine, comprising:

• a loading station for placing parts on a movable worktable connected to a rail car riding on a pair of rails and driven by a motor;
• a staging area for beginning the shot peening operation having a control panel cabinet housing start and stop pushbuttons to start and end the shot peening operation and further including electrical controls for controlling motors and sensors in the shot peening system such as the motors for an elevator, an auger, a dust collector system including a dust collector and a dust shaker, shot pit shakers;
• shot feeder and other electrical controls in the shot peening system like the valves on shot hoses between a shot hopper feeding the peening process;
• a shot peening chamber having rotary shot heads driven by a motor, the rotary shot heads mounted on a stationary roof of the shot peening chamber and angled at 45 degrees with respect to the axis of travel of the worktable, hoses with valves for controlling the shot fed from the shot hopper to the rotary shot heads;
• a containment chamber connected to the exit opening of the shot chamber for collecting the dust from the peening operation;
• a dust collection system including a dust box connected to an opening at a floor level of the containment chamber, a dust collection house having the dust collector motor and the dust shaker motor and a dust hopper for collecting the dust from the peening operation and a pipe extending from the dust box to the dust collection house for sucking the dust out of the containment chamber;
• and
• a shot pit located below a grate supporting the rails and pit shot hoppers below the grate for collecting used shot in the shot peening process and channeling it into pit shakers that move the shot to a deeper pit connected to an elevator with buckets for carrying the used shot out of the deeper pit to an auger above the shot chamber to carry the shot into a shot hopper that feeds the rotary shot heads mounted on the roof surface of the shot chamber through a series of hoses with valves controlling the shot fed into the rotary shot heads to control the intensity of the shot within the shot chamber.
