Abstract
The invention relates to a die casting manufacturing process of an aluminum alloy pump head. The process comprises the following steps: (1) raw material melting: transferring an aluminum alloy into a centralized natural gas melting furnace for melting the alloy; (2) vacuum die casting: pouring the molten aluminum alloy into a die cavity from a feed inlet of a die and meanwhile fully exhausting gas in the die cavity, and selecting low-speed, high-speed and pressurization parameters according to area of the feed inlet of the die, die casting weight, barrel size and pressurization ratio of a machine so as to perform die casting; (3) finishing the molded die casting part and removing burrs; (4) transferring the finished casting blank without the burrs into a machining center for machining; (5) washing the casting part machined in the machining center; and (6) packaging the washed casting part. By utilizing the process, the obtained aluminum alloy pump head passes continuous 72-hour no-leakage test under the pressure of 16MPa.
Description
Technical field
The present invention relates to die casting and make the field, particularly relate to the die casting manufacturing process of the aluminium alloy pump head of a kind of 16MPa of bearing.
Background technology
---material heating---punch forming---deflashing---Cutter Body Processing with Machining Center---cleaning---packing that the pump head material uses copper alloy to make usually in the prior art, and its processing technology is as follows: blanking.The copper alloy price is higher, and therefore in order to reduce cost, the material of pump head begins to turn to aluminium alloy.But the rigidity of aluminium is strong not as good as copper, and therefore the processing technology according to the copper alloy pump head is to allow the aluminium alloy pump head can bear the pressure of 16MPa, so need a kind of new die casting manufacturing process badly
Summary of the invention
Technical problem to be solved by this invention provides a kind of die casting manufacturing process of aluminium alloy pump head, and the aluminium alloy pump head that die casting is come out can not leak under 16Mpa pressure in test in continuous 72 hours.
The technical solution adopted for the present invention to solve the technical problems is: a kind of die casting manufacturing process of aluminium alloy pump head is provided, may further comprise the steps:.
(1) raw material material: aluminium alloy is sent into natural gas concentrate the thawing furnace material;
(2) evacuated die-casting process: will pour into mold cavity from the die feeding mouth through the aluminium alloy of changing material, simultaneously the gas in the mold cavity is fully discharged, and according to the pressure ratio of die feeding open area, die casting weight, barrel size and die casting machine choose low speed, at a high speed, the supercharging parameter carries out die casting;
(3) put the foundry goods of die cast in order deburring;
(4) will change Cutter Body Processing with Machining Center over to through the spray of arrangement deburring;
(5) foundry goods through Cutter Body Processing with Machining Center is cleaned;
(6) foundry goods that will clean is packed.
In the described step (1) liquation of aluminium alloy after through natural gas thawing furnace material utilized the insulation of board electric furnace, make temperature be controlled at design temperature ± 5 degree between.
Also comprise in the described step (2) heat energy-saving position of mould is done local cooling processing, the cold joint position of mould is done the step of local heat treated.
Described step (2) adopts the forced exhaust method that the gas in the mold cavity is fully discharged.
Between described step (2) and step (3), also comprise preceding 50 certified products are done the step of scrapping processing.
Aluminium alloy in the described step (1) is not handle through cinder ladle and stub bar feed back.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: the present invention is when carrying out evacuated die-casting process, by the conditions such as pressure ratio of charging aperture area, die casting weight, barrel size and machine choose suitable low speed, at a high speed, relevant parameter such as supercharging, to guarantee to have enough big casting pressure and suitable filling velocity, make the product interior solid, and adopt the forced exhaust method to carry out vacuum suction and better the gas in the die cavity was fully discharged in the moment of filling.
After aluminium alloy is concentrated the thawing furnace material with natural gas, utilize the insulation of board electric furnace, temperature is controlled at design temperature ± 5 degree, can control the shrinkage cavity of product inside so better, makes product inside finer and close.Guarantee the thermal balance of mould in press casting procedure, it is consistent that product is shunk, and mould thermal center and cold joint position are done local cooling and local heat treatment.In order to guarantee the uniformity of product interior tissue, taked preceding 50 mould products when cold mould begun to produce to do and scrapped processing.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention relates to a kind of die casting manufacturing process of aluminium alloy pump head, may further comprise the steps:
(1) raw material material: aluminium alloy is sent into natural gas concentrate the thawing furnace material, liquation behind the change material is utilized the insulation of board electric furnace, make temperature be controlled at design temperature ± 5 the degree between, can control the shrinkage cavity of product inside so better, make product inside finer and close.Slag inclusion and volume gas occur for fear of product, aluminum alloy materials is chosen the A380 aluminium alloy, and this aluminium alloy can not be done the feed back processing with cinder ladle and stub bar.
(2) evacuated die-casting process: will pour into mold cavity from the die feeding mouth through the molten aluminium alloy of changing material, simultaneously the gas in the mold cavity is fully discharged, and according to the pressure ratio of die feeding open area, die casting weight, barrel size and machine choose low speed, at a high speed, the supercharging parameter carries out die casting.Regulate carrying out the die casting parameter by various conditions,, make the product interior solid to guarantee that enough big casting pressure and suitable filling velocity are arranged.The present invention has adopted forced exhaust method-vacuum suction that the gas in the mold cavity was discharged fully in the moment of filling aluminium alloying material.In order to make product shrink unanimity, in press casting procedure, also need guarantee the thermal balance of mould, promptly the mould heat energy-saving position is carried out local cooling processing, local heat treatment is carried out at mold cold joint position.
(3) put the foundry goods of die cast in order deburring.
