Technical Field

The invention relates to a flatness shaping method, in particular to a flatness shaping method and a flatness shaping device for extrusion forming of an aluminum profile.

Background

The aluminium alloy adopts extrusion basically, comes out the back at the aluminium alloy from the mould, enters into the room temperature from high temperature environment promptly, because the difference in temperature is great, flat hollow aluminium alloy takes place to warp easily, leads to the plane degree not to meet the demands, owing to be hollow, and for flat aluminium alloy, later stage plastic difficulty causes permanent deformation or surface damage of aluminium alloy during the plastic easily. The flat aluminum profile is easy to form an arch shape, the upper surface and the lower surface of the flat aluminum profile are deformed towards the same direction, and the shaping of the surface deformed towards the inside of the aluminum profile is very difficult.

Therefore, it is necessary to correct the flatness of the flat hollow aluminum profile when the aluminum profile is discharged, but there is no suitable method or apparatus for correcting the flatness of the flat hollow aluminum profile.

Disclosure of Invention

In order to solve the problems, the invention provides an aluminum profile extrusion forming flatness shaping method which is simple in structure, convenient to use and capable of effectively correcting flatness when flat hollow aluminum profiles are discharged from a furnace, and the specific technical scheme is as follows:

the aluminum profile extrusion forming flatness shaping method is characterized in that graphite is tightly pressed on the side face of an aluminum profile to be shaped, and the graphite is located at an outlet of aluminum profile extrusion equipment.

By adopting the technical scheme, the graphite has a flaky crystal structure, has good lubricating property, and also has the characteristics of good electric conduction, heat conduction, wear resistance, pressure resistance, temperature resistance, chemical stability and the like.

The temperature of the aluminum profile at the outlet of the aluminum profile extrusion equipment is about 560 ℃.

Graphite can be high temperature resistant and self-lubricating, consequently can extrude the plastic to the aluminium alloy under the high temperature after the aluminium alloy is out of the stove, and the aluminium alloy this moment is softer, and the plastic is easy, and graphite is located the top of carrying the running roller, and graphite compresses tightly on the aluminium alloy, carries the running roller to support the aluminium alloy, realizes the plastic of aluminium alloy. Wherein the conveying roller is self-carried by the aluminum profile extrusion equipment.

Because graphite has a lubricating effect and the hardness is far lower than that of the aluminum profile, sliding friction can be performed between the graphite and the aluminum profile, and the graphite does not damage the surface of the aluminum profile.

The surface of the graphite for shaping can be a plane or a curved surface, the surface of the graphite for shaping is related to the flatness of the extruded aluminum profile and the flatness required by the product, and the shaping surface of the graphite is arranged according to actual conditions. The shaping surface of the graphite extrudes the side surface of the aluminum profile which is relatively soft at high temperature, and the flatness of the side surface of the aluminum profile is changed, so that the flatness of the aluminum profile after subsequent cooling meets the design requirement.

Although the extrusion forming of the aluminum profile is continuous, when one aluminum ingot is used up, the other aluminum ingot needs to be loaded, so that a certain time interval is provided, the graphite can realize certain cooling, and the temperature of the graphite is not too high.

The method provided by the invention has the best use effect only on flat hollow aluminum profiles, and can also be suitable for shaping the flatness of other aluminum profiles after extrusion.

Further, compress tightly graphite respectively on two sides that the aluminium alloy is parallel to each other, wherein at least one side is the face that needs the plastic.

Through adopting above-mentioned technical scheme, set up relatively through two graphite and compress tightly the aluminium alloy and improve the plastic effect, because the area of contact of carrying running roller and aluminium alloy is little, generally linear contact, it is less to the effective extrusion of aluminium alloy side to lead to graphite, extrude aluminium alloy jointly through two graphite and improved the area of contact of graphite with the aluminium alloy greatly, increased effective plastic area, make the aluminium alloy can keep certain effective extrusion time, thereby realize the plastic of aluminium alloy side plane degree.

Furthermore, the temperature of the graphite is reduced by spraying water to the graphite or immersing the graphite in water.

Through adopting above-mentioned technical scheme, graphite intensity sclerosis behind high temperature, and the graphite of sclerosis produces the mar easily to the aluminium alloy surface, sprays water or soaks the hardening temperature that the temperature that can effectively avoid graphite rises in aqueous graphite to graphite. The water keeps the graphite at a lower temperature, and the water quickly cools the graphite, so that the risk of scratches is effectively reduced, and the surface quality of the aluminum profile is improved.

Furthermore, when water is sprayed to the graphite, the water is not contacted with the aluminum profile; or the graphite is partially immersed in the water, and the water is not in contact with the aluminum profile.

By adopting the technical scheme, the contact surface of the aluminum profile and the graphite is not contacted with water, so that the determined interference factor is reduced, and the shaping effect is ensured.

The invention also aims to provide an aluminum profile extrusion forming flatness shaping device.

The aluminum profile extrusion forming flatness shaping device comprises a graphite pressing block, wherein the graphite pressing block is slidably pressed on the side surface of the aluminum profile to be shaped; and the pressing block fixing device is used for pressing the graphite pressing block on the side surface of the aluminum profile.

The aluminum profile further comprises a graphite cushion block, the graphite cushion block is arranged opposite to the graphite pressing block, and the graphite cushion block is pressed on the other side face, opposite to the side face, of the aluminum profile in a sliding mode; and the cushion block fixing device is used for pressing the graphite cushion block on the other side surface of the aluminum profile.

Through adopting above-mentioned technical scheme, use two graphite blocks from top to bottom to extrude the aluminium alloy to rectify the plane degree of aluminium alloy.

Furthermore, the graphite pressing block and the graphite cushion block are both horizontally arranged, the graphite pressing block is positioned above the aluminum profile, and the graphite cushion block is positioned below the aluminum profile; the cushion block fixing device comprises a positioning plate, the positioning plate is positioned below the aluminum profile, and the graphite cushion block is fixed on the positioning plate;

Through adopting above-mentioned technical scheme, spacing stand is used for the movable mounting of spacing shelves pole, conveniently dismantles spacing shelves pole when not needing to use the graphite briquetting when extruding other aluminium alloy.

The limiting stop lever blocks the graphite pressing block, so that the graphite pressing block does not move along with the aluminum profile, and the graphite is located at a constant position.

Furthermore, the graphite pressing block further comprises limiting columns, wherein the limiting columns are fixed on the limiting stop rods and are located on two sides of the graphite pressing block.
