An energy storage system for use in a magnetic pulse welding and forming apparatus includes a bank of capacitors and a very-low inductance conductive bus system interconnecting the capacitors. The bus system provides the ability to generate a very high frequency, short duration impulse which is needed for welding. The bus system includes first, second and third flat bus panels disposed in closely spaced overlying relation. The second, or middle, bus panel is the &ldquo;hot&rdquo; bus and is electrically insulated from the first (lower) and third (upper) bus panels by sheets of electrically insulating material. The first and third bus panels are connected together cooperatively form a ground bus. The bus system overlies the upper ends of the capacitors wherein the second bus panel is electrically interconnected to the respective hot contacts of the capacitors, and further wherein the ground bus is electrically interconnected with the respective ground contacts of the plurality of capacitors. The energy storage system further includes an energy source connected to the capacitors, a discharge device, a charging control device, and a discharge control device for selectively initiating discharge of energy stored in the capacitors. The bus system further includes removable connector elements that are selectively removable for controlling the total number capacitors utilized in the energy storage bank.

Energy storage apparatus for magnetic pulse welding and forming

An external inductor for magnetic pulse welding and forming includes an outer steel frame and an inner beryllium-bronze alloy insert which is removably mounted within the frame. The steel frame and the beryllium bronze insert respectively split the responsibility for higher mechanical strength and more concentrated pulse current on the inner surface of inductor's central opening. The improved external inductor design is capable of creating greater impulse forces onto the outer workpiece and has been demonstrated to perform at least 25-30% more deformation than a simple one piece simple steel external inductor for a full metallurgical joint.

An apparatus for delivering valves and melting rings for internal combustion engines to an inductor heater for hard facing comprises a tubular body which is adjoined by gravity feed trays, for feeding the work valves and rings to be melted respectively. A rotatable pocket is mounted between the tubular body and the tray for feeding the rings. The work valve and the ring to be melted are fed to the tubular body by gravity. Interaction with a stop mounted on the tubular body causes the valve to fall inside the tubular body with its stem being upwardly directed. After rotating, the pocket puts the ring to be melted onto the valve stem. The valve with the ring put thereupon is placed into the inductor for melting.

Apparatus for delivery of valves and melting rings to an inductor heater

An apparatus for delivery of melting rings and valves to an inductor heater, for hard facing of valves for internal combustion engines by melting rings of heat-resistant alloy upon the working surfaces of valves, comprises gravity feed trays, one for feeding the work valves in a vertical position and the other for feeding work rings laid on their side to a tubular body. Between the exit of the tray for feeding the rings and the tubular body there is installed a horizontal tray which is located under the gravity feed tray for feeding the valves and in the same vertical plane with said tray. The distance between the sliding surfaces of the tray along which the valve head moves and the sliding surfaces of the horizontal tray along which the ring lying on its side moves is less than the length of the valve stem, so that the valve stem enters the hole of the ring and delivers it to the tubular body. Near the upper end of the tubular body there is installed a stop interacting with the valve stem for positioning the valve falling into the tubular body with its stem being upwardly directed.

A coating is applied to a workpiece by ejecting a powdered material towards the workpiece using the energy of explosion in a recurrent cyclical operation. To produce an explosion, introduced into a combustion chamber of a detonation gun are a powdered coating material suspended in the stream of an inert gas and a gaseous explosive mixture formed by mixing a combustible gas and an oxidizing gas with or without an addition of an inert gas. During the coating process the explosive mixture is formed continuously, and cyclically filling the combustion chamber by portions of the explosive mixture is accomplished by feeding the inert gas to the pipe connecting the mixing chamber to the combustion chamber, which enables regular termination of the stream of explosive mixture and prevents the flame from spreading to the mixing chamber.

An apparatus for surfacing valves by fusing in a high-frequency current field refractory alloy rings applied to the seating surfaces of the valves. The apparatus comprises a tubular body provided with chutes adjoining thereto. The chutes are adapted respectively to feed valves and rings to be fused. After a valve and a ring is assembled under the action of gravity inside the tubular body, the valve with the ring to be fused is delivered by a pusher to a mechanism fixing the valve in a heater. The pusher is mounted for reversible movement in the hozizontal plane.

Surfacing is realized by fusing refractory alloy rings on the effective areas of valves. The apparatus comprises: a heater, a valve clamping device and a manipulator adapted to receive and to convey a valve with a ring on the stem thereof to the heater zone simultaneously positioning said valve head downwards. The manipulator is operatively connected to a platform on which a feed mechanism adapted to feed the valve to the heater and to the valve clamping device, a sprayer and an unloading chute are mounted. According to the motion of the manipulator the platform alternately positions under the heater the operating mechanisms mounted thereon.

A planetary air motor with two internal gearings employing two internally toothed ring gears. One ring gear rotates and meshes with a first rim of a two-rim pinion, the other gear forms an intertooth space with a second rim of the pinion that is freely mounted on an eccentric journal of a pinion carrier and has radial through slots in the tooth spaces. The intertooth space is limited by a flange at one face and by a fixed washer at the other face of the fixed gear and is divided into two intertooth working zones A and B. Zone A communicates with the compressed air line and the other one (B) with the atmosphere. The pinion carrier has a main channel and an additional channel with an inside bore that is smaller than that of the main channel and which is isolated from the latter. The additional channel is disposed towards the periphery of an eccentric journal of the pinion carrier and communicates with the compressed air line and the intertooth working zone A through a slot in the pinion carrier. The slot is where the fixed ring gear meshes with the pinion rim and is tangential to the cross section of the additional longitudinal channel. The main channel communicates with atmosphere through side holes in the pinion carrier, and zone B through a side port located in the zone where the fixed ring gear meshes with the other rim of the pinion.

A torch with a turbulized supply of a plasma forming gas comprises an electrode having a high-melting insert and a flat end face, and a nozzle with an internal surface having two mated portions: one cylindrical and one tapering; and the diameter of the electrode flat end face amounts essentially to 0.4-0.5 diameter of the electrode proper and the radius of conjugation of the nozzle cylindrical and tapering portions is equal essentially to the length of its cylindrical portion. Due to such a design, the inventive torch features a long service life of both the electrode and the nozzle.
