Description
Technical Field
The utility model relates to a vacuum sintering furnace.
Background
The existing vacuum sintering furnace has too large equipment area, so that the furnace body is heated unevenly. The structure is complicated, and the maintenance and the cleaning are inconvenient. Convection air inflow is generally adopted, the mode causes carburization at the center of a furnace body, size fluctuation is large, size tolerance is large after precision parts are sintered, and a sintering period is relatively long.
Disclosure of Invention
The utility model discloses to the problem that prior art exists, provide a vacuum sintering stove, can improve sintering size precision, reduce sintering size scope, be convenient for maintain the clearance, shorten product sintering cycle.
The utility model provides an above-mentioned technical problem adopted technical scheme as follows: the utility model provides a vacuum sintering furnace, includes the furnace body, sets up the seal box in the furnace body, its characterized in that the rear portion of seal box sets up interior intake pipe, and the front portion sets up the outlet duct, separates into the multilayer by a plurality of flitches in the seal box, and every layer of flitch position sets up the air inlet, the outlet duct connect the cooler, the cooler connect the fan, the fan connect interior intake pipe. The rear part of the seal box is enabled to intake air, the front part of the seal box exhausts air, and the air flow uniformly passes through each material plate, so that the size fluctuation range is small. The external fan and the oversized cooler improve the cooling efficiency.
The furnace body is also provided with an outer air inlet pipe, and air introduced by the outer air inlet pipe enters a region between the seal box and the furnace body. The inside and the outside of the seal box are respectively aerated, so that the furnace body atmosphere is more uniform.
Heating devices are symmetrically arranged on the left side and the right side in the sealing box. The left and right heating is adopted, and the temperature consistency is good.
The external part of the furnace body is connected in series with a first wax catcher and a second wax catcher through a main wax catcher pipeline, the second wax catcher is also connected with a vacuum pump, the second wax catcher is connected with the inlet end of the main wax catcher pipeline through a branch pipeline, the main wax catcher pipeline and the branch pipeline are respectively provided with a valve, and a valve is also arranged between the two wax catchers. Simple structure can select to open single wax trap or two wax traps as required, satisfies diversified production demand, and two catch and draw the ware structure and can improve and catch wax efficiency, the clearance of being convenient for.
The utility model discloses an improve the mode of admitting air, catch the wax structure, configured new cooling system structure, improved sintering size precision, the maintenance clearance of being convenient for shortens product sintering cycle, has improved cooling efficiency.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention.
Referring to fig. 1-3, the vacuum sintering furnace comprises a furnace body 1, a seal box 2 is arranged in the furnace body, an inner air inlet pipe 6 is arranged at the rear part of the seal box, an air outlet pipe 3 is arranged at the front part of the seal box, the seal box is divided into a plurality of layers by a plurality of material plates, an air inlet is arranged at the position of each layer of material plate, the air outlet pipe is connected with a cooler 4, the cooler is connected with a fan 5, and the fan is connected with the inner air inlet pipe.
An outer air inlet pipe 13 is also arranged on the furnace body, and the air introduced by the outer air inlet pipe enters the area between the seal box and the furnace body. The left and right sides of the sealed box are symmetrically provided with heating devices 14. The outside of the furnace body is connected in series with a first wax catcher 10 and a second wax catcher 8 through a main wax catcher pipeline 12, the second wax catcher is connected with a vacuum pump 7, the second wax catcher is connected with the inlet end of the main wax catcher pipeline through a branch pipeline 9, valves 11 are respectively arranged on the main wax catcher pipeline and the branch pipeline, and a valve is also arranged between the two wax catchers.
The utility model reduces the volume of the device to one third of the original device, heats the device simultaneously from left to right, and is heated evenly. Air is fed into the rear part of the seal box, air is exhausted from the front part of the seal box, and airflow uniformly passes through each material plate, so that the size fluctuation range is small. The inside and the outside of the seal box are respectively aerated, so that the furnace body atmosphere is more uniform. The wax catching efficiency is improved by adopting a double-catching-pulling device structure, and the cleaning is convenient. The external fan and the oversized cooler improve the cooling efficiency.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
