Abstract
Provided is a staggered type guide rail structure for a kiln. Side rails (2) are arranged on opposite positions on the two sides of a track supporting seat of the push-plate type kiln. A plurality of guide rails are arranged on the track supporting seat on the inner sides of the two side rails (2). Each guide rail is formed by splicing a plurality of guide rail combination bodies (1), and each guide rail combination body (1) is of a strip shape. The staggered type guide rail structure is characterized in that joints between adjacent guide rail combination bodies (1) are arranged in a staggered mode instead of being on the same position, a fixed structure of each guide rail combination body (1) has a thermal expansion quantity and bears the thermal expansion quantity independently without transferring pushing force generated by the thermal expansion quantity independently to the other guide rail combination bodies (1), as a result, deformation caused by the thermal expansion quantity can be reduced, and the functions that the guide rails are protected against deformation, plate warping and plate humping are achieved.
Description
Technical field
The utility model belongs to push-plate type kiln technical field, particularly for the brand-new design of the guide rail structure of push-plate type kiln, has and avoids that guide rail distortion, plate stick up, effect of arch bar.
Background technology
In the preparation technology of electronic component or powdered metallurgical material, need with sintering or heat treatment in push-plate type kiln, sintering or heat treatment are a considerable technique, the quality of electronic component or powdered metallurgical material product quality because sintering or Technology for Heating Processing concern.Push-plate type kiln is mainly by body of heater, interior feed track, outer feed track and exchange system form, this interior feed track is located at body of heater inside, and the exchange system of body of heater two sides is located in link, outer feed track is located at body of heater outside, and link the exchange system of body of heater two sides, using the shift-in plate turnover kiln as carrying storing electronic component to be sintered, kiln main body is distinguished and is had intensification sintering stage and cooling section according to technique, in intensification sintering stage, there is heat-resisting material and look the temperature required heating element heater of sintering procedure, cooling section has cooling device, referring to push-plate type kiln in Fig. 1 prior art, because its guide rail is all that order is arranged, due to the restriction of technique, the size of the Refractory blocks of each guide rail is restricted, and because be that solid Refractory blocks forms, in transportation, shift-in plate passes in and out kiln repeatedly, and the interior temperature of kiln is generally at 1350 DEG C to 1500 DEG C, because impelling the volume of each guide rail, the effect of expanding with heat and contract with cold changes, siege easily has some setbacks because the variation of expanding causes its shift-in plate operation of carrying of generation, even there is guide rail distortion, plate sticks up, arch bar, cause card stove accident, or three grooves rub out on shift-in plate, reduce the service life of shift-in plate.This is prior art and has maximum disappearance, and this disappearance is into the difficult problem that industry urgently overcomes.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of kiln alternating expression guide rail structure, the utility model is particularly for the brand-new design of the guide rail structure of push-plate type kiln, a kind of kiln alternating expression guide rail structure, on the rail supported seat two side relative positions of push-plate type kiln, siding track is set, article two, on the rail supported seat of siding track inner side, several guide rail is set, described per pass guide rail is made up of the splicing of several piece slide rail composite unit, every slide rail composite unit is strip, and the cohesive position setting of staggering between adjacent slide rail composite unit, at same position.The thermal expansion amount all in the fixed structure of every slide rail composite unit with self, every slide rail composite unit bears separately the thermal expansion amount of self, does not transmit to other slide rail composite units the thrust that thermal expansion amount produces.Avoid to reduce the distortion that causes of thermal expansion amount, to have that guide rail distortion, plate stick up, effect of arch bar.
As optimal technical scheme, between each slide rail composite unit, there is gap.
Preferably, each slide rail composite unit is that the heat-resistant, wear-resistant materials such as carborundum or corundum form, and can obtain preferably heat conduction, heat-resisting and lubricity.
Preferably, each siding track is that the heat-resistant, wear-resistant materials such as carborundum or corundum form, and can obtain preferably heat conduction, heat-resisting and lubricity.
The aforementioned slide rail composite unit of the utility model is strip and is crisscross arranged, and avoids adjacent rails to be connected in same position, shift-in plate is advanced more smooth and easy, and can avoid shift-in board stove or the generation of the accident of three grooves that rub out on shift-in plate.
Brief description of the drawings
Accompanying drawing 1 prior art middle guide is arranged schematic diagram;
Accompanying drawing 2 the application's guide rails are arranged schematic diagram.
Detailed description of the invention
Referring now to accompanying drawing 2, embodiment of the present utility model is elaborated:
A kind of kiln alternating expression guide rail structure, on the rail supported seat two side relative positions of push-plate type kiln, siding track (2) is set, article two, on the rail supported seat of siding track (2) inner side, several guide rail is set, described per pass guide rail is made up of several piece slide rail composite unit (1) splicing, every slide rail composite unit (1) is strip, and the cohesive position setting of staggering between adjacent slide rail composite unit (1), at same position.In the fixed structure of every slide rail composite unit (1), all there is the thermal expansion amount of self, every slide rail composite unit (1) bears separately the thermal expansion amount of self, does not transmit to other slide rail composite units (1) thrust that thermal expansion amount produces.Avoid to reduce the distortion that causes of thermal expansion amount, to have that guide rail distortion, plate stick up, effect of arch bar.
As optimal technical scheme, between each slide rail composite unit, there is gap.
Preferably, each slide rail composite unit is that the heat-resistant, wear-resistant materials such as carborundum or corundum form, and can obtain preferably heat conduction, heat-resisting and lubricity.
Preferably, each siding track is that the heat-resistant, wear-resistant materials such as carborundum or corundum form, and can obtain preferably heat conduction, heat-resisting and lubricity.
The beneficial effects of the utility model are: slide rail composite unit is strip and is crisscross arranged, avoid adjacent rails to be connected in same position, the distortion causing to reduce thermal expansion amount, have and avoid that guide rail distortion, plate stick up, effect of arch bar, shift-in plate is advanced more smooth and easy, and can avoid shift-in board stove or the generation of the accident of three grooves that rub out on shift-in plate.
Although above-mentioned explanation by way of example; the detailed description of the invention of the utility model the best has been described; protection domain of the present utility model is not limited in above-mentioned explanation; persons skilled in the art are understandable that; do not deviating under the prerequisite of essence that the utility model instructs and marrow, any modifications and variations all fall into protection domain of the present utility model.
