Abstract
The utility model discloses a uniform temperature extrusion die using cascade temperature regulation. The die is characterized by comprising an upper heating ring (1), a middle heating ring (2) and a lower heating ring (3) around the outer surface of the die (5) as well as heating pipes (4) uniformly distributed at the bottom of the die (5) along the circumference. The heating powers of the upper heating ring (1), the middle heating ring (2), the lower heating ring (3) and the heating pipes (4) increase successively. The die disclosed by the utility model solves the technical problem that in the extruding moulding process of the extrusion die, temperatures of metal meltwater everywhere in the die are equal, and the microstructures of a moulding piece everywhere are similar.
Description
Technical field
The utility model relates to the extrusion die field, relates in particular to the thermoregulator samming extrusion die of a kind of employing staged.
Background technology
Along with the continuous speed-raising of China railways, locomotive running speed improves constantly, and firmly influence is also more and more obvious to the wheel track action for unsprung mass, therefore, reduces a technical barrier that must solve when unsprung mass has become the highspeed rail vehicle design.Adopt the locomotive of six connecting rod Hollow Shaft Transmission modes, half quality of drive sleeve belongs to unsprung mass, therefore can obviously reduce unsprung mass by the quality that reduces hollow shaft, improves the wheel track action firmly, improves the dynamic performance of locomotive.
Express locomotive adopts extrusion casint in process of production with the aluminium alloy drive sleeve, and in the process of squeeze casting mould, the first step need add molten metal bath in mould.High-temperature molten metal liquid rapid heat dissipation, in casting process, the molten metal bath heat radiation that enters at first in the extrusion die is maximum, and temperature is minimum.Because it is high that express locomotive requires the material microstructure with the aluminium alloy drive sleeve, in extrusion process, should guarantee that the temperature at each position of material is identical.Traditional extrusion die cannot be realized above requirement.
The utility model content
Technical problem to be solved of the present utility model is to guarantee at extrusion die in the extrusion modling process, and everywhere metal melting liquid temp is identical in the mould, and guarantees that profiled member microstructure everywhere is similar.
For realizing above purpose, the technical solution adopted in the utility model: the thermoregulator samming extrusion die of a kind of employing staged, it is characterized in that: it comprises last heating collar (1), middle heating collar (2), the heating collar (3), and the heating tube (4) that is evenly distributed on mould (5) bottom along circumference down that is looped around mould (5) outer surface; The heating power of last heating collar (1), middle heating collar (2), following heating collar (3), heating tube (4) increases progressively successively.
Under preferable enforcement situation, described mould (5) is provided with point for measuring temperature (6), middle point for measuring temperature (7), following point for measuring temperature (8), bottom point for measuring temperature (9); Last point for measuring temperature (6), middle point for measuring temperature (7), following point for measuring temperature (8), bottom point for measuring temperature (9) connect moisture recorder (10) by circuit.
The beneficial effects of the utility model: by be looped around mold outer surface on heating collar, middle heating collar, heating collar down, guarantee that in the process of extrusion modling mould inside temperature everywhere is consistent.Mould is provided with point for measuring temperature, middle point for measuring temperature, following point for measuring temperature, bottom point for measuring temperature; Last point for measuring temperature, middle point for measuring temperature, following point for measuring temperature, bottom point for measuring temperature connect moisture recorder by circuit; Thereby realize real-time monitoring and record to inner each point temperature.
Description of drawings
Fig. 1 is structural representation of the present utility model.
On the way described numerical reference is expressed as: 1, go up heating collar; 2, middle heating collar; 3, following heating collar; 4, heating tube; 5, mould; 6, go up point for measuring temperature; 7, middle point for measuring temperature; 8, following point for measuring temperature; 9, bottom point for measuring temperature; 10, moisture recorder.
The specific embodiment
In order to make those skilled in the art understand the technical solution of the utility model better; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises last heating collar 1, middle heating collar 2, the heating collar 3, and the heating tube 4 that is evenly distributed on mould 5 bottoms along circumference down that is looped around mould 5 outer surfaces; The heating power of last heating collar 1, middle heating collar 2, following heating collar 3, heating tube 4 increases progressively successively.Described mould 5 is provided with point for measuring temperature 6, middle point for measuring temperature 7, following point for measuring temperature 8, bottom point for measuring temperature 9; Last point for measuring temperature 6, middle point for measuring temperature 7, following point for measuring temperature 8, bottom point for measuring temperature 9 connect moisture recorder by circuit.
Owing to the temperature loss of the molten metal bath that is introduced into mould is big, temperature can be lower than the back and inject the interior molten metal bath of mould, for head it off, the technical scheme of employing is: the heating power of going up heating collar 1, middle heating collar 2, following heating collar 3, heating tube 4 increases progressively successively.
Need to prove, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby make and comprise which key element process, method, article or the equipment of a series of key elements not only comprise, but also comprise other key elements of clearly not listing, or also be included as the intrinsic key element of this process, method, article or equipment.Do not having under the situation of more restrictions, the key element that is limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises key element and also have other identical element.
Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.The above only is preferred embodiment of the present utility model, should be understood that, because the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be made up by rights; These improve retouching, change or combination, or without improving the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
