The before-forging constant-temperature heating furnace comprises a furnace outer frame and a furnace inner frame, wherein the furnace inner frame is arranged inside the furnace outer frame by a supporting post; a bracket is respectively arranged on the two ends of the furnace inner frame; a charging guide rail, a furnace wire tube and a cooling rod are arranged on the bracket; the two ends of the charging guide rail respectively stretch out from the furnace outer frame; a furnace wire is arranged inside the furnace wire tube; the two ends of the furnace wire are fixedly connected with the cooling rod; the other end of the cooling rod is connected with an outer circuit; an outer thermal insulation layer is arranged between the furnace outer frame and the furnace inner frame; an inner thermal insulation layer is arranged between the furnace inner frame and the furnace wire tube; a temperature sensor sleeve gets through the furnace inner frame and the furnace outer frame and is fixed on the inner thermal insulation layer and the outer thermal insulation layer; and a temperature sensor is arranged on the temperature sensor sleeve. The before-forging constant-temperature heating furnace can heat up the blank to a forgeable temperature range, the heating efficiency is high, the furnace outlet temperature of the blank can be accurately controlled, thus the production cost is greatly saved and the quality of the product is improved.
Description
Technical field
The utility model is a kind of heating furnace, thermostatic oven before particularly a kind of valve is forged, and this heating furnace can be heated to malleable temperature range with blank.
Background technology
The process of valve, wherein requisite operation is with heating furnace blank to be forged preceding heating.But the present firing equipment efficient that adopts is very low, and its most important reason is that existing equipment is to be heating tool with the kerosene blastburne, and heating environment is open, and heat runs off a lot, and energy utilization rate is extremely low.On the other hand, current heating technique is difficult to accurately control temperature, makes that the blank temperature fluctuation of coming out of the stove is big, has greatly influenced the quality of final valve.
Summary of the invention
The purpose of the utility model is that the preceding heating technique thermal efficiency of existing valve forging is low in order to overcome, temperature is controlled inaccurate defective; Invent a kind of valve and forge preceding thermostatic oven; This heating furnace can not only improve the thermal efficiency greatly, and can accurately control the blank tapping temperature.
The purpose of the utility model realizes as follows: thermostatic oven before said valve is forged, comprise stove housing and stove inside casing, and the stove inside casing is located in the stove housing through pillar; The two ends of stove inside casing respectively are provided with a support, and the central authorities of support have one or more feed lead rail holes, and the periphery in feed lead rail hole has a plurality of furnace thread pipes hole, and the outside in furnace thread pipe hole is provided with a plurality of cooling stick bushing slots; Be provided with feed lead rail through the feed lead rail hole, stretch out from the stove housing respectively at the two ends of feed lead rail; Be provided with furnace thread pipe through the furnace thread pipe hole, the two ends of furnace thread pipe are embedded on the furnace thread pipe installing hole, are provided with the stove silk in the furnace thread pipe; The cooling stick bushing slot is provided with the cooling stick sleeve pipe, and the cooling stick sleeve pipe is provided with cooling stick; The two ends and the cooling stick of stove silk are affixed, and the other end of cooling stick is connected with external circuit; Be provided with external thermal insulation between stove housing and the stove inside casing, be provided with inner thermal insulating layer between stove inside casing and the furnace thread pipe; One temperature sensor sleeve pipe pass stove inside casing and stove housing and be fixed on inner thermal insulating layer and external thermal insulation on, the temperature sensor sleeve pipe is provided with temperature sensor.
The good effect of the utility model is following: the utility model can be heated to blank the scope of malleable temperature, and its efficiency of heating surface is high, and can accurately control the tapping temperature of blank, has practiced thrift production cost and the quality that has improved product greatly.
