Abstract
The invention relates to a horizontal extruding technology for a flat aluminium pipe. The technology comprises the following steps of: getting raw material bars, cleaning, heating, carrying out heat insulation treatment, and extruding the processed bars, thus obtaining a flat pipe. With the adoption of the horizontal extruding technology, the defects of products are reduced, the production efficiency is improved, the cost of the production is reduced, and the higher environment-friendly performance is achieved.
Description
Technical field
The present invention relates to the horizontal extrusion process of a kind of aluminium flat conduit.
Background technology
Along with rapid development of automobile industry; Improve the auto parts and components production domesticization and become an important problem; Existing country nowadays also advocates environmental emission reduction energetically, in the time of owning a car also to car require increasingly highly, the air conditioning for automobiles performance has become a good important examination link of automobile; Yet condenser is again and is important in air conditioning for automobiles, and the quality of condenser will directly have influence on the cooling or heating effect of air conditioning for automobiles.
At present, do automotive air-conditioning condenser on the market and roughly be divided into two kinds with the machine of aluminium flat conduit: a kind of is continuous extruder, and another kind is a horizontal extruder.Through producing and destructive test, find that product slip of flat tube after processing condenser of continuous extruder reaches 10～15 ‰, and have a large amount of bubbles aborning, aluminium bits, defectives such as misrun.Product slip of flat tube after processing condenser reaches 5～8 ‰ when utilizing the horizontal extruder general technology to make flat tube; On extrusion production flat tube surface ponding is arranged easily, the surface is exposed in the air, very easily corrosion; Be easy to wear out, seriously reduced the service life of flat tube.
Summary of the invention
To above-mentioned shortcoming, the technical issues that need to address of the present invention provide the horizontal extrusion process of a kind of aluminium flat conduit.
The technical scheme that the present invention adopts is:
The horizontal extrusion process of a kind of aluminium flat conduit may further comprise the steps:
(1) raw material: clean the raw material bar, then the raw material bar is put into electric furnace and heat, heating-up temperature is 530～540 ℃, and be 4～5 hours heat time heating time;
(2) mould: mould, die sleeve are put into heating furnace heat, then mould is packed in the die sleeve, 500～510 ℃ of mold heated temperature heated 2～3 hours, and 380～420 ℃ of die sleeve heating-up temperatures heated 1～2 hour;
(3) extruding: the die sleeve that mould will be housed is respectively packed in the extruder, and the raw material bar is put into recipient, the raw material bar is clamp-oned mould form flat tube, and the recipient temperature is 420～430 ℃, and extrusion speed is 210～230mpa;
(4) spray zinc and cooling:, cool off fast through supercooled water then at flat tube surface spraying zinc layer;
(5) take-up: flat tube is wound into the plate-like flat tube.
Warm water with 30～40 ℃ in the said step (1) cleans the raw material bar.
All dry up surperficial remaining ponding after cleaning raw material bar and flat tube cooling in said step (1) and the step (4) with compressed air.
Advantage of the present invention is: reduced the defective of product, improved production efficiency, reduced production cost, more environmental protection.
The specific embodiment
The horizontal extrusion process of a kind of aluminium flat conduit of the present invention may further comprise the steps:
(1) raw material: choosing diameter is 100 millimeters, and the aluminium bar material that length is 410 millimeters cleans the aluminium bar material with 35 ℃ warm water, and dries up the aluminium bar material with compressed air, then the aluminium bar material is put into electric furnace and is heated to 530 ℃, heated 4 hours, and insulation;
(2) mould: mould, die sleeve are put into heating furnace heat, then mould is packed in the die sleeve, mold heated to 500 ℃ heated 2 hours, and die sleeve is heated to 380 ℃, heats 2 hours;
(3) extruding: the die sleeve that mould will be housed is respectively packed in the extruder, and the aluminium bar material is put into recipient, and the temperature of recipient is 430 ℃, extruding then, and squeezing pressure is 220mpa, the aluminium bar material is squeezed into mould forms aluminium flat conduit;
(4) spray zinc and cooling: carry out the low-tension arc thermal spraying on the aluminium flat conduit surface, spraying zinc layer cools off through supercooled water then fast, and aluminium flat conduit cooling back is with the quiet and deserted remaining ponding that dries up the flat tube surface of dry compression;
(5) take-up: aluminium flat conduit is wound into the plate-like flat tube.
The present invention has reduced the defective of product, has improved production efficiency, has reduced production cost, more environmental protection.
Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
