The synchronous two-way opposite purging equivalent temperature normalizing rapid cooling chamber is characterized in that upper arc tile-shaped folded plates (7) are fixed on the surrounding wall on the upper portion in the room outer shell (1), the chimney (6) is fixed on the rear side portion on the top wall of the chamber outer shell (1), the middle portion in the chamber outer shell (1) is provided with a channel (9) which is communicated with an inlet of the chimney (6), compared with existing devices which are used in rapid cooling chambers for purging hot processing workpieces upwards and downwards, since blowing air can blow the upper surfaces and the lower surfaces of the hot processing workpieces simultaneously and synchronously under the blowing of one fan, the temperature reduction of the hot processing workpieces can be even, the cooling speed is consistent, and the synchronous two-way opposite purging equivalent temperature normalizing rapid cooling chamber not only can improve the hot processing quality and reduce the waste product rate, but also has simple structure and easy operation and control, and can be widely used in cross wedge rolling production lines.
Description
Technical field
The utility model relates to the improvement of the interior heat treated part quick cooling chamber of stove in a kind of isothermal normalizing heat-treatment production line, and specifically a kind of synchronous bidirectional is to blowing the isothermal normalizing quick cooling chamber.Be applicable to a class part isothermal normalizing heat treatment step.
Background technology
The isothermal normalizing stove comprises High Temperature Furnaces Heating Apparatus, constant-temperature oven, quick cooling chamber and blowing device, material transfer mechanism, heating system and electrical means, need the workpiece of heat treated at first to arrive desired austenitizing temperature at the High Temperature Furnaces Heating Apparatus internal heating, push quick cooling chamber by push rod again, when in quick cooling chamber, drying the temperature range that is cooled to set with fast speeds by blowing device, rapidly heat treated part is pushed and carry out isothermal in the constant-temperature oven, the beginning phase transformation also keeps this temperature to finish until phase transformation.The isothermal normalizing thermal treatment process is because of obtaining organizing relatively evenly and the less relatively forged steel pieces of nonhomogeneous hardness is widely used in treatment production.Described quick cooling chamber comprises chamber enclosure, the heat treated part push-in door, air-cooled back workpiece is released door, blower fan, airduct and chimney constitute, the air outlet of airduct is fixedlyed connected with the bottom centre of chamber enclosure, chimney is fixed on the roof middle part of chamber enclosure, the blast inlet of airduct is connected with blower fan, cold wind is blown into from the bottom centre of chamber enclosure, blow to the bottom surface of heat treated part, around heat treated part, around above heat treated part, entering chimney blows out, the heat treated part push-in door is located at an end that is connected with High Temperature Furnaces Heating Apparatus, and air-cooled back workpiece is released door and is located at an end that is connected with constant-temperature oven.The quick cooling chamber of this structure, because the bottom surface that cold wind directly blows heat treated part causes the bottom surface of heat treated part to form malleation, cold blast rate is big, cooling is fast; And heat treated part above, periphery is an eddy current, the center then forms negative pressure, cooling rate is slow.This upper and lower temperature contrast of heat treated part can cause heat treated part hardness inhomogeneous or metallographic structure is defective, and scrap rate rises; Particularly when a plurality of heat treated parts are cooled off simultaneously fast, also can produce the notable difference of speed of cooling and respective phase change effect between each heat treated part, cause and occur distributing eutectoid ferrite, Widmannstatten structure, bainite even martensite improperly in heat treated part part or the global tissue, and and thick perlite form phenomenons such as mixed grain structure, make road processing difficulties behind the heat treated part, degradation.For addressing this problem, what have has increased switch and converting system on airduct, pass through switch, for a moment from the bottom surface of heat treated part to up-draught, for a moment again from the blowing that faces down of heat treated part, though certain effect is arranged, cooling is intermittent, so can not thoroughly solve the uneven problem of cooling; The minimizing that has heated components Intake Quantity or increase spacing between the heated components, but influence working efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of can neither influence working efficiency from the cooling of drying simultaneously of the upper and lower both direction of heat treated part, and the synchronous bidirectional that can make the quick uniform decrease in temperature of heat treated part again is to blowing the isothermal normalizing quick cooling chamber.
For reaching above purpose, the technical scheme that the utility model adopted is: this synchronous bidirectional is to blowing the isothermal normalizing quick cooling chamber, comprise chamber enclosure, the heat treated part push-in door, air-cooled back workpiece is released door, blower fan, airduct and chimney constitute, the air outlet of airduct is fixedlyed connected with the bottom centre of chamber enclosure, the blast inlet of airduct is connected with blower fan, cold wind is blown into from the bottom centre of chamber enclosure, blow to the bottom surface of heat treated part, around heat treated part, around above heat treated part, the heat treated part push-in door is located at an end that is connected with High Temperature Furnaces Heating Apparatus, air-cooled back workpiece is released door and is located at an end that is connected with constant-temperature oven, arc watt shape flap on it is characterized in that fixing on the top perisporium in chamber enclosure, around the blowing above heat treated part, flow along arc watt shape flap, force blowing to be turned back, blow to heat treated part above, chimney is fixed on the rear lateral portion on the chamber enclosure roof, middle part in chamber enclosure is provided with the passage that communicates with the chimney import, and the top blowing that blows to heat treated part enters chimney along the passage that communicates with the chimney import.
The utility model is also implemented by following measure: arc watt shape flap is inboard to be 25-35cm along the distance above heated components, and the channel diameter that communicates with the chimney import is than the big 2-4 of air outlet diameter times of airduct.
The beneficial effects of the utility model are: with use in quick cooling chamber at present the upper and lower device that blows of heat treated part is compared, because under the blowing of same blower fan, blowing can be simultaneously, synchronously to the above and below of heat treated part to blowing, cause the heat treated part lowering temperature uniform, the speed of cooling unanimity, can not only improve thermal treatment quality, reduce scrap rate, and simple in structure, easy handling control.
