Abstract
The utility model discloses a vacuum oil quenching furnace for salt bath, which comprises a horizontal furnace body; and the vacuum oil quenching furnace is characterized in that a front chamber and a rear chamber are arranged in the horizontal furnace body, a middle gate valve is arranged between the front chamber and the rear chamber, one end of the middle gate valve extends out of the horizontal furnace body, a horizontal conveying wagon and a lifter are arranged in the front chamber, the lifter is arranged below the horizontal conveying wagon, a vertical lifting mechanism and a salt bath heating pool are arranged in the rear chamber, and the salt bath heating pool is arranged at the bottom of the rear chamber. According to the utility model, the furnace body is vacuumized in a salt bath heating mode, and workpieces are completely soaked into the salt bath heating pool, so that the heating speed is increased, and the heating is uniform.
Description
Technical field
The utility model designs a kind of vacuum oil quenching, particularly the vacuum oil quenching of a kind of workpiece homogeneous heating, high efficiency.
Background technology
Present vacuum oil quenching generally is the mode that adopts graphite heating, under vacuum state, does not have transmission medium during owing to the workpiece heating, so the process of the heating of workpiece, finishes by radiation often.But exist the workpiece shady face in the slower problem of heating, and when heating, cause heating easily inhomogeneous.For so that the workpiece pro and con all is heated to preset temp, heat consuming time longlyer, cause working (machining) efficiency not high.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum oil quenching, the workpiece homogeneous heating, and working (machining) efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum oil quenching, comprise horizontal body of heater, its innovative point is: be provided with two chambers in cup and rear chamber in the described horizontal body of heater, slide valve in the middle of being provided with between described cup and rear chamber, slide valve one end stretches out horizontal body of heater in the middle of described, be provided with in the described cup horizontal material conveying trolley with and the elevator of below, the described rear indoor salt bath heating pond that is provided with vertical lifting mechanism and bottom, rear chamber.
Further, described vertical lifting mechanism mainly is comprised of the traveling nut on lifting motor, screw rod, the screw rod and the charging basket that links to each other with traveling nut, described workpiece places charging basket, described screw rod one end is fixed on the horizontal inboard wall of furnace body, the other end stretches out horizontal body of heater, its terminal lifting motor that connects.
The utility model has the advantage of: the utility model has adopted the mode of salt bath heating, body of heater is vacuumized, and so that workpiece is fully immersed in the salt bath heating pond, it is fast to have improved rate of heating, and homogeneous heating.
On the horizontal material conveying trolley of cup in the charging basket of workpiece transfer in the vertical lifting mechanism of rear chamber, utilization is arranged on the lifting motor drive screw rod that rear chamber outer wall arranges, screw rod drives the charging basket direct-connected with traveling nut, so that the workpiece in the charging basket is fully immersed in the salt bath heating pond.
Description of drawings
Fig. 1 is synoptic diagram of the present utility model;
Embodiment
A kind of vacuum oil quenching shown in Figure 1 is mainly horizontal body of heater 2, and its inside is provided with 10 two chambers of cup 9 and rear chamber, slide valve 4 in the middle of 10 of cup 9 and rear chambers are provided with, and middle slide valve 4 one ends stretch out horizontal body of heater 2.Be provided with in the cup 9 horizontal material conveying trolley 7 with and the elevator 1 of below, be provided with the salt bath heating pond 8 of vertical lifting mechanism and bottom, rear chamber in the rear chamber 10.Vertical lifting mechanism mainly is comprised of the traveling nut 53 on lifting motor 51, screw rod 52, the screw rod and the charging basket 54 that links to each other with traveling nut, and workpiece places charging basket 54; Vertically disposed screw rod 52 1 ends are fixed on horizontal body of heater 2 inwalls, and the other end stretches out horizontal body of heater, its terminal lifting motor 51 that connects.
During specific works, first workpiece is packed on the horizontal material conveying trolley 7 in the cup 9, close fire door, vacuumize and rear chamber is heated to preset temp, heat salt bath heating pond 8 this moment, make it to reach quenching temperature, then open the middle slide valve 4 of 10 of cup 9 and rear chambers, utilize the horizontal material conveying trolley 7 of elevator 1 driving to rise to preset height, then make horizontal material conveying trolley 7 level runs, workpiece is placed charging basket 54 on the vertical lifting mechanism, and level run trolley 7 descended and also returned in the cup 9 this moment, closed the middle slide valve 4 between cup and rear chamber.Vertical lifting mechanism after then utilizing in the chamber 10 is so that charging basket 54 slow decreasings, so that the workpiece in the charging basket enters in the salt bath heating pond 8 fully.Heat complete after, vertical lifting mechanism drives charging basket 54 and rises, open the middle slide valve 4 between cup and rear chamber, horizontal material conveying trolley 7 in the tangential movement cup 9 is transported to cup 9 with workpiece, slide valve 4 in the middle of closing, can take out workpiece after work-piece cools, move in circles, the workpiece that reinstalls second batch operates.
