Description
Technical field
The utility model relates to a kind of preheating device, particularly relates to a kind of preheating device for powder metallurgy push rod type sintering furnace.
Background technology
At present, sintering furnace body mostly is the cylindrical shell in chamber, and body of heater front end is the entrance for pushing sintered products; porch is placed with fire door, and fire door and body of heater form closed furnace chamber jointly, is being attached thereto under the air pump effect connect; furnace chamber can vacuum, also can be flooded with protective gas or refrigerating gas.Between body of heater with fire door, the horizontal plane that adopts is connected more, and the Heating Zone Temperature setting of burner hearth is greater than 600 DEG C substantially, and the volatilization of lubricant is a process slowly, and whole volatilization just can complete substantially below 600 DEG C.The drawback of this connection is that in sintering furnace body, each temperature difference in sintering zone is large, poor controllability, after product enters burner hearth from outside normal temperature, due in burner hearth with outside excessive temperature differentials, the very fast intensification of product, easily causes the sharply gasification of product in-lubricant, and product size becomes large, density reduces, there is tiny cavity in outer surface, occurs epidermis Decrepitation Phenomena time serious.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of preheating device for powder metallurgy push rod type sintering furnace, solves product density and reduces the problem even producing explosion.
The technical solution of the utility model is such: a kind of preheating device for powder metallurgy push rod type sintering furnace, be installed on dewaxing device front end, comprise body of heater, described body of heater front end is provided with pay-off, be provided with baffle plate in described body of heater, body of heater is divided into preheating zone and the thermal treatment zone by described baffle plate, and described baffle plate is provided with the through hole being communicated with preheating zone and the thermal treatment zone, described through hole bore is variable, and the described thermal treatment zone is provided with heater.
In a preferred embodiment of the present utility model, described baffle plate can vertically move in body of heater, and described preheating zone and the thermal treatment zone change volume with the mobile of baffle plate.
In a preferred embodiment of the present utility model, described heater is ferrum-chromium-aluminum electric-heating-wire-heating device.
In a preferred embodiment of the present utility model, described body of heater is stainless steel stove.
In a preferred embodiment of the present utility model, described stainless steel stove external sheath iron sheet.
In a preferred embodiment of the present utility model, the insulation materials such as described stainless steel furnace internal-lining outer cladding glass fibre.
Preheating device for powder metallurgy push rod type sintering furnace of the present utility model, has and improves the feature such as product quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view.
Fig. 2 is baffle arrangement schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Incorporated by reference to Fig. 1 and Fig. 2, a kind of preheating device for powder metallurgy push rod type sintering furnace, be installed on dewaxing device front end, comprise body of heater 1, body of heater 1 front end is provided with pay-off 4, body of heater 1 is provided with the baffle plate 5 that can vertically move along body of heater 1, and furnace inner space is divided into preheating zone 3 and the thermal treatment zone 2 by baffle plate 5, and the volume between preheating zone 3 and the thermal treatment zone 2 is different according to the diverse location of baffle plate 5.Baffle plate 5 is provided with the through hole 6 being communicated with preheating zone 3 and the thermal treatment zone 2, the bore of through hole 6 be by block 51 be in diverse location time and variable.By the different sizes of through hole 6, and the intensity that the different sizes of the diverse location of baffle plate 5 thermal treatment zone 2 of causing and preheating zone 3 heat that controls the thermals treatment zone 2 spreads to preheating zone 3.The thermal treatment zone 2 is provided with heater, and its temperature controls at 150 DEG C ~ 600 DEG C, and heater is ferrum-chromium-aluminum heater, and body of heater 1 is stainless steel stove, stainless steel stove external sheath iron sheet, the insulation materials such as stainless steel furnace internal-lining outer cladding glass fibre.
Preheating device for powder metallurgy push rod type sintering furnace of the present utility model, be installed on dewaxing device front end, during work, product is sent into the preheating zone 3 of body of heater 1 by pay-off 4, by the heat radiation of the heater of the thermal treatment zone 2, preheating is carried out to the product in stove, if directly product is sent into the thermal treatment zone 2, the cold and hot exchange of product, easily causes the explosion of product.But owing to being provided with baffle plate 5 in stove, the heat of the thermal treatment zone 2 by the through hole 6 on baffle plate 5 slowly infilter preheating zone 3, after 15-20 minute, the product of preheating zone 3 is through heating slowly, the wax remaining in product surface is divested, and internal stress also part removal, then send preheating zone 3 and enter the thermal treatment zone 2, enter follow-up sintering again, cooling.Therefore the preheating device for powder metallurgy push rod type sintering furnace of the present utility model, has and improves the feature such as product quality and production efficiency.
