Rare earth aluminum alloy profile extruding die

Abstract

The invention relates to a rare earth aluminum alloy profile extruding die comprising a deflector (1), a die seat (2), a forming die plate (6) and a wear bush (7). A plurality of deflector holes (3) are reserved in the middle of the deflector (1) vertically. A material extruding hole (4) is arranged inside the deflector (1). A matching boss (10) is arranged on the lower portion of the deflector (1). The die seat (2) is of a hollow structure, a matching groove (11) is arranged on the top of the die seat (2), and the matching groove (11) is matched with the matching boss (10) tightly. A groove (12) is arranged inside the die seat (2), and the wear bush (7) is mounted inside the groove (12) in a matching manner, and is connected with the forming die plate (6) in a matching manner. A pre-profiled hole (8) penetrating through the upper face and the lower face of the forming die plate (6) is reserved on the forming die plate (6). The rare earth aluminum alloy profile extruding die has the advantages that structure is simple, die service life is long, die interchangeability is strong, and maintenance cost is low.

Description

technical field [0001] The invention relates to a die, in particular to a rare earth aluminum alloy extrusion die. Background technique [0002] Aluminum has good extrusion formability, light specific gravity, good strength, good economy, environmental protection and recyclability, so aluminum is widely used in technical fields such as industry and decoration. At this stage, the processing of aluminum profiles is mostly done through hot extrusion dies. [0003] Aluminum profile extrusion dies generally include a die and a punch. During the extrusion process, the aluminum alloy material is continuously extruded through the die and punch. Under the action of high-pressure friction, the surface of the die is easy to wear, which affects the production of profiles. quality. For this reason, people use the method of carburizing and nitriding the surface of the mold to strengthen the hardness of the mold. However, under high temperature conditions, the wear resistance of the mold...

Problems solved by technology

[0003] Aluminum profile extrusion dies generally include a die and a punch. During the extrusion process, the aluminum alloy material is continuously extruded through the die and punch. Under the action of high-pressure friction, the surface of the die is easy to wear, which affects the production of profiles. quality

For this reason, people use the method of carburizing and nitriding the surface of the mold to strengthen the hardness of the mold. However, under high temperature conditions, the wear resistance of the mold still cannot meet the production needs, and it needs to consume a large amount of synthetic nitrogen and carbon components. Material, high cost of nitriding and carburizing process

The thickness of the carburized layer is generally only 30 μm to 50 μm. A set of molds needs to work continuously for more than 5 hours for each carburizing treatment, which greatly affects the processing efficiency of aluminum alloy profiles.

[0004] Chinese patent application number: 20060038905.3 discloses an aluminum profile extrusion die for assembly line. It adopts the combination of upper and lower dies. The large core in the middle and the small cores in the periphery are connected by reinforcing ribs. The stability and strength of the mold core, but the wear resistance of the forming hole has not improved. When the wear of the forming hole seriously affects the quality of the aluminum alloy profile, the mold needs to be replaced. The mold with this structure cannot realize the replacement of the main parts, and The cost of the mold itself is very high, so the cost of the mold has brought a lot of pressure to the manufacturer

In addition, the mold body and the forming hole are integrally formed, and the product is single, which cannot meet the needs of different customers
