Abstract
The utility model discloses a vacuum sintering furnace, which comprises a furnace frame, a furnace body and a vacuum pump, wherein a heating body is arranged in the furnace body; a thermal insulation layer is arranged between the heating body and the furnace body; an air vent is formed on the furnace body and is communicated with the vacuum pump; and a hydrocylinder for controlling the opening and the closing of the air vent is arranged on the vacuum pump. The vacuum sintering furnace is high in safety performance and durable in use.
Description
Technical field
The utility model relates to vacuum drying oven, relates in particular to a kind of hard alloy vacuum sintering furnace.
Background technology
In cemented carbide industry, mainly contain vacuum drying oven in the sintering equipment, a kind of vacuum drying oven of the prior art, comprise grate, be arranged at body of heater on the described grate, be used for vavuum pump that described body of heater is vacuumized, offer passage on the described body of heater, be provided with slidably the sprue that described passage is blocked on the common described body of heater, block described passage by magnetic valve by the described sprue of magnetic force moving, after the permanent use of magnetic valve, electromagnetism easily disappears.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of security performance high and long-lived vacuum sintering furnace.
The utility model is achieved by the following technical solution:
Vacuum sintering furnace, comprise grate, body of heater, vavuum pump, be provided with heater in the described body of heater, be separated with heat-insulation layer between described heater and the body of heater, be provided with passage on the described body of heater and communicate with vavuum pump, also be provided with the hydraulic jack of the described passage closure or openness of control on the described body of heater.
Also be provided with on the described body of heater and send hydrogen mouth and ignitron, the closure or openness of hydrogen mouth are sent in described hydraulic jack control.
Described hydraulic jack comprises cylinder barrel, piston, piston rod, and described piston is used for blocking described passage, and an end of described piston rod is connected with described piston, and the other end of described piston rod is connected with described cylinder barrel.
The utility model compared with prior art has following beneficial effect: control described passage and the closure or openness that send the hydrogen mouth by hydraulic jack, security performance is high and durable in use.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment,
Sequence number among the figure: 1, grate, 2, body of heater, 3, vavuum pump, 4, passage, 5, hydraulic jack, 6, send the hydrogen mouth, 7, ignitron, 8, cylinder barrel, 9, piston, 10, piston rod.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to shown in Figure 1, a kind of vacuum sintering furnace of the utility model, comprise grate 1, body of heater 2, vavuum pump 3, be provided with heater in the described body of heater 2, be separated with heat-insulation layer between described heater and the body of heater 2, be provided with passage 4 on the described body of heater 2, send hydrogen mouth 6 and ignitron 7, described passage 4 communicates with vavuum pump 3, also be provided with the described passage 4 of control and the hydraulic jack 5 that send hydrogen mouth 6 closure or openness on the described body of heater 2, described hydraulic jack 5 comprises cylinder barrel 8, piston 9, piston rod 10, described piston 9 is used for blocking described passage 4 and send hydrogen mouth 6, one end of described piston rod 10 is connected with described piston 9, and the other end of described piston rod 10 is connected with described cylinder barrel 8.
The semi-finished product for the treatment of vacuum-sintering are placed on send into the utility model body of heater on the pallet, close the state that is evacuated behind the fire door, again by sending the hydrogen mouth to send into hydrogen, open ignitron row hydrogen and try quick-fried rear igniting, and open power-cutting switch, heat up by heater, in temperature-rise period, hydrogen constantly burns, and the forming agent in the product is resolved into gaseous state together, discharges by passage.Close according to technological requirement and to send the hydrogen mouth, vavuum pump will be evacuated in the stove, and to reaching predetermined temperature, vacuum-sintering is finished in cooling after the insulation by the heater heating direct.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
