Description
Technical field
The present invention relates to a kind of transformator volume core annealing stove.
Background technology
At present, large-scale rewinding material is big due to its core volume, the feature of Heavy Weight, determine this iron core particularly bigger at the speed difference of initial stage temperature rise period each site absorption heat energy unshakable in one's determination when annealing, each position intensification speed is different, it is easy to causes Stress Release uneven, how to make full use of furnace inner space, reasonable Arrangement hot plate, making each position unshakable in one's determination thermally equivalent as far as possible, do not expend unnecessary electric energy, reaching again intended annealing effect is key point.Simultaneously because its core volume of high-power transformer rewinding material is big, the feature of Heavy Weight, if large-tonnage material platform vehicle participates in annealing with conventional vehicle or dolly are the same in the lehr with workpiece unshakable in one's determination, so expect that the driving rolls of platform vehicle not only to carry tens of tons of rewinding material weight in a long time, also to bear the high temperature of annealing furnace in a long time simultaneously, so severe working condition will certainly cause the driving rolls deformation of material platform vehicle, thus causing workpiece unshakable in one's determination cannot exit annealing furnace after annealing completes.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, a kind of transformator volume core annealing stove is provided, it is it can be avoided that iron core cannot exit the phenomenon of annealing furnace after having annealed, can be efficient, complete the annealing work of high-power transformer volume iron core easily and reach intended annealing target.
In order to solve above-mentioned technical problem, the technical scheme is that a kind of transformator volume core annealing stove, it includes body of heater and material platform vehicle, material platform vehicle includes material sewing platform base, track, installing rack, roll wheel assembly, the material platform of lifting assembly and placement iron core, track is arranged on the bottom of body of heater, and pass the door side of body of heater, described roll wheel assembly is rotatably installed on installing rack, roll wheel assembly and track match, material platform is placed on the movable end of lifting assembly, lifting assembly is fixedly connected on installing rack and enters after body of heater for material hoisting platform with box lunch installing rack, described material sewing platform base is arranged on the bottom of body of heater for use in a bearing platform.
Further for enabling to be positioned at the iron core thermally equivalent of body of heater, the upper wall of described furnace body inside, diapire, left wall, You Bi, rear wall and the forehearth shop front are disposed with heat-insulation layer and zone of heating outward by inner.
Further provide the structure of a kind of material platform so that iron core can horizontal placement and multi-layer stacking thus avoid owing to large-scale volume core dimensions is big, Heavy Weight and the deformation that occurs in annealing process, take full advantage of again the useful space of annealing furnace simultaneously, described material platform includes at least two-layer iron core and places plate, and adjacent iron core is placed and supported by gripper shoe between plate.
Further for avoiding the iron core of lower floor during heat temperature raising in annealing process it is possible that each site absorption heat energy non-uniform phenomenon of iron core is so that homogeneous heating degree when improving the core annealing of lower floor, transformator volume core annealing stove also includes interlayer heater, this interlayer heater includes heating connecting plate, connector and interlayer hot plate, interlayer hot plate is installed on the supporting plate, and it is positioned at the top of the iron core being placed on iron core placement plate, one end of heating connecting plate is arranged on the zone of heating of body of heater, the other end of heating connecting plate is connected with interlayer hot plate by connector.
Further for the opening and closing of the fire door facilitating door of annealing furnace side, in described track, the track at door side place is mounting structure removably.
Further, described lifting assembly is hydraulic cylinder.
After have employed technique scheme, the iron core of required annealing can be contained in material platform by expecting that material platform is placed on material sewing platform base after being transported to annealing furnace middle finger allocation by platform vehicle by the present invention, it is then log out annealing furnace, again the iron core annealed is sent annealing furnace by material platform vehicle after end to be annealed, it is thus possible to avoid iron core cannot exit the phenomenon of annealing furnace after having annealed, can be efficient, complete the annealing work of high-power transformer volume iron core easily and reach intended annealing target.
Accompanying drawing explanation
