No. 545 - Shotgun Assembly

Product catalog summary

Single Station Brazing Machine Specifications

Assembly: The process involves brazing a steel gas block and guide ring to a steel shotgun barrel.
Induction Heat: Utilizes two RDO 15 kW induction power units with two coils and a 5-ton water chiller.
Paste Filler Metal: Fusion STK-1205-750 (BAg 7), cadmium-free, with a liquidus temperature of 1205°F (651°C).
Production Rate: Capable of producing 25 parts per hour with one operator. Heat time is 45 seconds, and cycle time is 150 seconds.
Dimensions: The machine has a 36” X 50” aluminum extrusion frame with induction control units and a water chiller positioned nearby.
Utilities: Requires electrical input of 480 VAC, 3PH, 40 amp, control voltage of 24VDC, and compressed air at 5 CFM.
PLC: Equipped with an Allen Bradley Micrologix 1500 and a Panel View Plus 400 operator interface.
Safety Features: Includes perimeter guarding on three sides with safety interlocks, a light curtain for emergency stop function, and a vent hood for fume extraction.

Sequence of Operation

The operator loads the shotgun barrel into the pasting fixture.
Brazing paste is dispensed on the gas block and guide ring using an MLF applicator gun, then positioned on the barrel.
The pasted assembly is transferred to the heating fixture.
The heating fixture lifts the assembly into induction heat coils to reach brazing temperature.
After the heating cycle, forced air cooling occurs, the fixture retracts, and the operator unloads the brazed assembly.

Additional Information

A hand-held applicator gun dispenses a pattern of paste filler metal to the gas block.
Two induction coils heat the silver brazing filler metal to a liquidus temperature of 1305°F.
Control units for induction power supplies allow monitoring of power output, voltage, frequency, and current.
