Abstract

DC60 (07/01/57) A heat-hardening device with a gas-heating furnace inside. Hydrocarbons and oxygen aggregation gases are imported. in which the outlet opening of the valve (30) through which the pusher (27) for pushing the work will be heat-hardened in the quenching furnace. By heating through the sliding channel, it is spliced in such a way that air cannot enter. Slots for insertion of pushers made in the wall (28) of the heat treatment furnace and The seal housing (31) is connected to the valve inlet (30) in such a way that air does not enter, the pusher (27) is movable. Inaccessible by air through the seal housing (31), the lift door (4) for opening and closing the heat treatment furnace has a pilot pin (32) protruding from it and a polishing mechanism. hull (35), which has an upper articulated face (33) for receiving, pilot pins (32); When the elevator door (4) is lowered, the elevator door (4) is moved by the polishing mechanism (35) towards the sealing surface of the heat treatment furnace opening. ) For the guide pin (39) of the elevator door (4) in the vertical direction is bent at the bottom. of that part towards the sealing surface of the heat treatment furnace opening. The sealing plate (41) is arranged on the sealing surface of the heat treatment furnace opening and mechanism. The heat pipe (42) is arranged close to the sealing plate. (41) A heat-hardening device with a heat-treating furnace in which gas is contained within. Hydrocarbons and oxygen aggregation gases are imported. in which the outlet opening of the valve (30) through which the pusher (27) for pushing the work will be heat-hardened in the quenching furnace. By heating through the sliding channel, it is spliced in such a way that air cannot enter. Slots for insertion of pushers made in the wall (28) of the heat treatment furnace and The seal housing (31) is connected to the valve inlet (30) in such a way that air does not enter, the pusher (27) is movable. Air ingress through the seal housing (31), the lift door (4) for opening and closing the heat treatment furnace has a guide pin (32) protruding from that part and the interrupting mechanism. (35), which has an upper knurled surface (33) for accepting a guide pin (32) on it, a grooved lapping mechanism (35) that will support it so that it can be rotated according to the pivot When the elevator door (4) is lowered, the elevator door (4) is moved by the polishing mechanism (35) towards the sealing surface of the heat treatment furnace opening. ) For the guide pin (39) of the elevator door (4) in the vertical direction is bent at the bottom. of that part towards the sealing surface of the heat treatment furnace opening. The sealing plate (41) is arranged on the sealing surface of the heat-treating furnace opening and mechanism. The heat pipe (42) is arranged close to the sealing plate ( 41)

Claims (3)
