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.

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 wear-resistant composite material incorporating a refractory chemical compound in particulate form and an alloy matrix. The particles contain between 7 and 30 wt.% of chromium, between 30 and 40 wt.% of boron, the balance being titanium, have a size between 0.3 and 2 mm and are present in an amount between 40 and 80 vol.%, the balance being the alloy matrix. The material has an improved resistance to wear and consists of comparatively cheap and widely abundant ingredients.
