Description
Technical field
The utility model relates to a kind of mold clean field, is specifically related to a kind of aluminium alloy extrusion mould cleaning equipment.
Background technology
Aluminum or aluminum alloy section bar, after extrusion die is shaping, extrusion die remains some aluminium alloys usually, in order to use next time these moulds to produce, must remove the aluminium scrap in extrusion die.Extrusion die is directly put into alkali groove by traditional method, allows alkali lye and aluminium produce chemical reaction, is removed by the aluminium scrap remained to reach in mould.The feature of this process is discharged by the corrosion of aluminium alloy in the tap hole of mould and seam chamber thereof by the method for alkali cleaning.But the present inventor finds after have passed through long-term practice, there is following shortcoming in this technique: 1. automaticity is not high.Above each processing step is that a dead lift or handling can realize, and like this, operating efficiency is not high, makes the labour intensity of workman larger yet; 2. boil die worker people be in compare rugged environment under work.Because alkali cleaning pond is boiling in mold process, due to chemical reaction, when boiling mould, create a large amount of not only heat (generally at about 95 ~ 130 DEG C) but also unpleasant alkali vapor; 3. the wasting of resources.The alkali cleaning time needed for aluminium alloy residual in this PROCESS FOR TREATMENT mould is long, also needs a large amount of caustic soda and aluminium alloy to react, and a large amount of caustic soda can not get reclaiming, but also contaminated environment.So, a large amount of steams is produced during above-mentioned alkali cleaning, the best way is also taken out by a part of steam at the side air exhauster in alkali cleaning pond, like this, a lot of steam is still to space ascension, this is serious environment pollution not only, have impact on the healthy of operator, is also the significant wastage to resource (aluminium hydroxide).
So the present inventor has invented a kind of Al and Alalloy and extrusion die boils mould separation method and equipment in November, 2011, as follows:
1. Chinese patent: (application number is: 201110378418.2) for Al and Alalloy and extrusion die alkali cleaning separation method and equipment, disclose a kind of Al and Alalloy and extrusion die alkali cleaning separation method and equipment, be characterized in: adopt the method for automatically boiling mould alkali cleaning and being separated, its technique comprises alkali cleaning, cleaning, pickling, cleaning, air-dry, the step being separated and putting in storage, aluminium alloy extrusion mould is the indoor closed, there is continued operation in stable conveyer belt, it is high that this Al and Alalloy and extrusion die alkali cleaning separation method and equipment have automaticity, economize on resources, the features such as safety and environmental protection.
But the present inventor finds through using after a period of time, also technique should there are some defects, this be due to: 1. the nitric acid used in cleaning process, sulfuric acid cannot be recycled, and have not only wasted resource but also to environment; 2. the oxide in the die surface after having cleaned and tap hole and seam chamber also in more residual oxides, particularly tap hole and seam chamber, can make mould have a great impact aluminium alloy extrusions quality when next time uses; 3. the alkali cleaning time is long, inefficiency, and alkali cleaning was for up to more than 6 hours.
