The aluminum alloy quantitative pouring pump has the advantages of being large in quantitative pouring range, high in quantitative accuracy, long in service life, free of pollution in the aluminum liquid, low in cost, needless to be maintained for a long term, and the like.
Description
Technical field
The present invention relates to smelting non-ferrous metal and casting field.Especially a kind of aluminium alloy quantitative pouring pump particularly applies to the aluminium alloy compression casting field.
Technical background
Aluminum alloy die casting, as auto parts and components commonly used, obtained large-scale utilization at vehicle, the pouring type of aluminum current alloy die cast mainly is at special holding furnace and the soup feeding machine of the other configuration of die casting machine, manipulator by soup feeding machine drives the soup ladle motion, aluminium liquid in the holding furnace is scooped into the pressure chamber of die casting machine.Adopt soup feeding machine, exist equipment investment large, soup ladle is generally the cast iron manufacturing, often coating prevents aluminium liquid to its corrosion, moreover the service life of soup ladle is shorter, need often to change, also have, because the soup ladle corrode is in aluminium liquid, cause aluminium liquid composition polluted by iron tramp, affect casting quality, in addition when changing the die-cast product kind, because the different soup weight of giving, need to readjust soup feeding machine or change soup ladle and carry out manual adjustment, comparatively numerous and diverse, also affect production efficiency.For above-mentioned situation, external comparatively advanced aluminium stove has begun to adopt the mode of pressure pouring, carry out the quantitative pouring of aluminium die casting, the mode of this cast is similar to low-pressure casting, it is the bell sealing with holding furnace, apply a pressure by the inside furnace of giving sealing, aluminium liquid is extruded from liquid outlet, flow into again the pressure chamber of die casting machine by chute, realize feed, this system need to accurately control technological parameters such as the pressure of giving gas and flows, various precise pneumatic elements are many, cost is high, the adjusting of technological parameter is complicated, only can find application at comparatively high-quality smelting furnace, and, this arts demand seals the smelting furnace of working under the condition of high temperature, operation easier is large, high to material requirements, for getting rid of ambient pressure to the impact of smelting furnace internal pressure, also limited the smelting furnace heat source way and selected, generally can only adopt electric heating to carry out the insulation of smelting furnace, and can't use more cheap natural gas etc. as thermal source insulation and fusing, above-mentioned reason has limited the extensive utilization of air pressure quantitative pouring mode on a large amount of common aluminum alloy machine limit stoves that exist of China jointly.
Summary of the invention
The objective of the invention is, for the deficiencies in the prior art, using for reference magnesium alloy pouring adopts mechanical pump that magnesium liquid in the smelting furnace is promoted and quantitative pouring, and need not to adopt the present situation of soup feeding machine, overcome existing magnesium alloy pouring pump and all adopt the heat resisting steel manufacturing, the metal materials such as invar iron are dissolved in extremely rapidly the physical characteristic in the aluminium alloy melt, as directly the magnesium pump being used for the cast aluminum alloy, pump will damage in the short time at the utmost point, for above-mentioned situation, the present invention be intended to with aluminium liquid high temperature under do not infiltrate, do not react, the high nonmetallic materials of intensity are for the manufacture of a series of aluminum alloy machinery pouring pumps.This pump can use for a long time, and need not to safeguard, quantitatively scope is large, and quantitative accuracy is high, compares to soup feeding machine and pressure pouring, and cost is low, control is simple, easy to operate.
Realize that concrete technical scheme of the present invention is:
A kind of aluminium alloy quantitative pouring pump, it comprises pump barrel, pump pole, bearing block, bearing, gear aluminium dish, liquid outlet, motor and shaft joint, pump pole lower end can be screw rod, shaft flow rotor or other mechanism that liquid level can be promoted in rotary course, pump pole upper end is installed on the center of bearing block by brearing bore, there is a flange bearing block upper end, be used for mounted motor, end flanges is connected by bolt or pressing plate with the pump barrel upper flanges under the bearing block, motor is connected by shaft joint with the pump pole, and pump pole middle part is equipped with a gear aluminium dish near the liquid outlet place.
The pump barrel of this pump, pump pole, liquid outlet and gear aluminium dish be characterised in that material therefor all or part of by high temperature resistant, do not infiltrate and the manufacturing of nonreactive high strength nonmetallic materials with aluminium, or by the outside complex fire resistant of metal material, do not infiltrate with aluminium and nonreactive high strength nonmetallic coating forms.
The inner installation shaft of the bearing block of this pump is honoured the pump pole and is carried out axially and radial location, and bearing ensures in the process of pump rod High Rotation Speed in pump barrel and the pump barrel bump, prevents partly or entirely the damage of the part made by nonmetallic materials.
For preventing that the lifting owing to liquid level in the pump work process of aluminium liquid from entering in the bearing block of metal manufacturing, cause aluminium liquid to the corrode of bearing block and internal bearings thereof, one gear aluminium dish is installed on the pump rod, and its setting height(from bottom) is near liquid outlet top, and shelves aluminium dish external diameter and pump barrel difference in internal diameters are less than 1 millimeter.
