Abstract
The utility model discloses a three-point type pouring gate for manufacturing an aluminum alloy transmission hollow shaft for a high-speed locomotive. The three-point type pouring gate comprises a pouring gate I (1), a pouring gate II (2) and a pouring gate III (3), and is characterized in that the pouring gate I (1), the pouring gate II (2) and the pouring gate III (3) are uniformly distributed right above an arc-shaped hole of a guide locating ring (4) in 120-degree angles and incline downwards for 15-25 degrees; a thermocouple (8) is arranged at the outlet end of each of the pouring gate I (1), the pouring gate II (2) and the pouring gate III (3). The technical problem to be solved by the utility model is to achieve the effects of improving the filling velocity and filling quality of a molten metal by reasonably arranging the position and amount of the pouring gates.
Description
Technical field
The utility model relates to a kind of for the manufacture of the bikini running channel of express locomotive with the aluminium alloy drive sleeve.
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.If running channel is arranged the quality that efficient and drive sleeve are poured into a mould in influence very little, arrange too much as running channel, increased production cost.Whether the layout of running channel and structure be reasonable, is directly connected to the speed of molten metal bath filling velocity and the height of filling quality.
The utility model content
Technical problem to be solved in the utility model is by the position of reasonable Arrangement running channel and quantity, improves molten metal bath filling velocity and filling quality effect and reach.
For realizing above purpose, the technical solution adopted in the utility model is: a kind of for the manufacture of the bikini running channel of express locomotive with the aluminium alloy drive sleeve, it comprises running channel I (1), running channel II (2) and running channel III (3); It is characterized in that: described running channel I (1), running channel II (2) and running channel III (3) evenly be 120 ° of arcuate sockets that are distributed in guide-localization circle (4) directly over, all downward-sloping 15 °～25 ° of above-described three running channels; The port of export of described running channel I (1), running channel II (2) and running channel III (3) is provided with thermocouple (8).
Described running channel I (1), running channel II (2) and running channel III (3) all are provided with heating resistor (5), and heating resistor (5) is outside equipped with heat-insulation layer (6), and heating resistor (5) is outside equipped with heat-insulation layer (6).
The beneficial effects of the utility model:
Described running channel I, running channel II and running channel III evenly be 120 ° of arcuate sockets that are distributed in the guide-localization circle directly over, all downward-sloping 15 °～25 ° of above-described three running channels, so that molten aluminium alloy liquid flows into die cavity fast, reduced the loss of molten aluminium alloy liquid temperature in flow process.
At running channel I, running channel II and the running channel III port of export one thermocouple is set, in conjunction with temperature control system, monitors the molten aluminium alloy liquid temp of the running channel port of export at any time, guarantee the reliability of pouring temperature.
Lay heating resistor in running channel I, running channel II and running channel III bottom, in time replenish the thermal loss of molten aluminium alloy liquid; Electrically heated rod is connected with temperature controller.
Lay one deck heat-resistant insulation material in running channel I, running channel II and running channel III, prevent thermal loss effectively.
