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.

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.

Apparatus for surfacing internal combustion engines valves

A tank furnace comprises a first container containing a molten flux and connected with a hoisting mechanism, and a second container containing a molten coating metal. The second container is stationary mounted so as to be placed inside the first container when in its upper position. The mechanism for advancing articles into the coating zone is connected with a device for controlling the depth of immersion of the articles being coated. The first container is fitted with electrodes.

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.

Apparatus for surfacing valves for internal combustion engines

An apparatus is designed for hard-facing internal combustion engines valves by the melting and fusion in high-frequency current field of heat-resistant rings of hard alloy upon the seating surface of the valves. The apparatus comprises an actuator means mounting gripping jaws and a support which is adapted to receive the ring and to feed it onto the valve stem at the moment the valve being gripped by the jaws. The actuator associates with a manipulator adapted to provide for turning movement thereof in two mutually perpendicular planes, thereby conveying the valve with the ring positioned on its seating surface from the receiving area fusion or welding zone, the valve stem being upwardly directed at the same time. The apparatus features high efficiency owing to combining the steps of putting the alloy ring on the valve and conveying the latter to the welding or fusion zone.
