Abstract
The present invention relates to an oil-quenching and air-cooling vacuum furnace. The oil-quenching and air-cooling vacuum furnace comprises a furnace body, a walking mechanism for a workpiece, a vacuum system, a cooling system, an electric control system and an oil quenching processing system. The oil-quenching and air-cooling vacuum furnace further comprises an oil circulation apparatus for the oil-quenching and air-cooling vacuum furnace. The oil circulation apparatus comprises an oil outlet arranged on a side wall of the furnace body, an oil inlet arranged on the side wall of the furnace body, an oil pump connected with the oil outlet, a temperature controller, wherein both ends of the temperature controller are respectively connected with the oil pump and the oil inlet. The oil outlet, the oil pump, the temperature controller and the oil inlet are connected through oil pipes. The temperature controller is provided with a temperature detecting apparatus and an automatic heating or cooling apparatus. According to the present invention, the temperature controller is adopted to detect and regulate the oil pumped through the oil pump so as to reduce the loss of the oil; the regulated oil is conveyed to the furnace body and is continuously used so as to realize the oil recycling and save the cost; the oil-quenching and air-cooling vacuum furnace provided by the present invention has characteristics of simple structure and convenient operation.
Description
Technical field
the present invention relates to a kind of oil quenching gas cooling vacuum furnace.
Background technology
oil quenching gas cooling vacuum furnace is mainly used in the bright quenching of materials such as steel alloy, structural alloy steel, mould steel, spring steel, bearing steel, stainless steel, Precise Alloy steel and sintering, clean annealing and the vacuum brazing of magneticsubstance.At present, oil quenching gas cooling vacuum furnace generally comprises travel mechanism, vacuum system, cooling system, electrical control system, the oil quenching system of processing of body of heater, workpiece, therefore; Under the effect of oil quenching system of processing, very high with the processing of the temperature of oil just can be played the effect of oil quenching; Yet secular processing, the temperature of oil is increasingly high, when being higher than required temperature; Then caused the waste of resource, production cost is also than higher simultaneously.
Summary of the invention
technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of oil quenching gas cooling vacuum furnace is provided.
For solving above technical problem, the present invention takes following technical scheme:
a kind of oil quenching gas cooling vacuum furnace; This oil quenching gas cooling vacuum furnace comprises travel mechanism, vacuum system, cooling system, electrical control system, the oil quenching system of processing of body of heater, workpiece; Described oil quenching gas cooling vacuum furnace also comprises the oil circulation device that is used for oil quenching gas cooling vacuum furnace; Wherein oil circulation device comprises the thermostat that sidewall of the furnace body oil outlet and oil-in, the oil pump that is connected with oil outlet and two ends are connected with oil-in with oil pump respectively is set; Connected by oil pipe between oil outlet, oil pump, thermostat, the oil-in, thermostat is provided with temperature-detecting device and heats automatically or refrigerating unit.
further enforcement of technical scheme according to the present invention: the temperature of thermostat is controlled at 65～100 ℃.
preferably, oil outlet is arranged on sidewall of the furnace body bottom.
preferably, oil-in is arranged on the sidewall of the furnace body and is higher than the residing position of workpiece.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
the present invention adopts thermostat, and the oil that oil pump is extracted out detects and regulates, and has reduced oily loss; Oil after will regulating simultaneously is delivered in the body of heater, continues to use, and has realized oil circulation use; Practice thrift cost, and simple in structure, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing and concrete embodiment, the present invention is done further detailed explanation:
Fig. 1 is the structural representation of the oil quenching gas cooling vacuum furnace according to the present invention;
wherein: 1, body of heater; 10, oil outlet; 11, oil-in; 2, cooling system; 3, oil quenching system of processing; 4, oil pump; 5, thermostat; 6, oil pipe; 7, workpiece.
