Problems solved by technology

[0003] In the existing aluminum profile molding dies, extrusion dies with a fixed core are generally used. The core is the shape required by the profile without any diversion or buffer position. After the aluminum profile is forced to be extruded, the metal characteristics of the aluminum profile may be produced Changes, resulting in fracture, low toughness, and deformation of the internal cavity of the aluminum profile after forming.

Embodiment 1

[0030] refer to Figure 1-4 , a forming die for aluminum profiles, comprising an extruded tube 1, an upper module 7 and a lower module 8 are installed in the extruded tube 1, a mold core 9 is fixed on the upper module 7 and the lower module 8, the upper module 7 and the lower module 8 are provided with a plurality of first installation holes 18, and the extruded tube 1 is provided with a plurality of second installation holes, and the plurality of second installation holes correspond to the plurality of first installation holes 18 one by one. A locking screw 10 is installed between the mounting hole 18 and the second mounting hole;

[0031] The upper module 7 is symmetrically provided with a plurality of first fixing holes 19, the lower module 8 is symmetrically provided with a second fixing hole 20, and the mold core 9 is symmetrically welded with two mounting strips 23, and each mounting strip 23 is provided with a A plurality of third fixing holes 24, a plurality of first ...

Embodiment 2

[0041] S1: First, weigh out the materials, 20 kg in total, and each metal is composed of each mass percentage: copper 0.4, manganese 0.15, magnesium 1.2, zinc 0.25, chromium 0.35, titanium 0.15, silicon 0.8, iron 0.7, and the balance of aluminum ingots. Put 20 kg of mixed material into the melting furnace for melting, and set the temperature to 740°C. After melting, remove the scum and gas through degassing and slag removal to prevent the slag and gas from affecting the alloy performance, and then pour the alloy liquid Enter the die-casting machine for die-casting, and the alloy liquid is die-cast into a cylindrical aluminum alloy.

[0042] S2: Heating the cylindrical aluminum alloy to the critical point of liquefaction of the aluminum alloy, at this time the cylindrical aluminum alloy softens, put the softened cylindrical aluminum alloy into the feed trough 2 on the extruded tube 1, and then start the extruder, The extrusion rod in the extrusion tube 1 drives the extrusion bl...

Abstract

The invention discloses an aluminum profile forming method. The aluminum profile forming method comprises the first step of casting, the second step of extrusion, the third step of straightening, thefourth step of aging and the fifth step of surface treatment. The invention further discloses an aluminum profile forming die, an extrusion pipe is included, and an upper die block and a lower die block are arranged in the extrusion pipe and jointly fix a die core. The die core, the upper die block and the lower die block are detachable mechanisms, only the die core needs to be replaced during profile die replacement, and material cost is saved; through various levels of flow guiding grooves, softened cylinder aluminum can be more smoothly extruded into buffering grooves and a forming groove;through the various levels of buffering grooves, in the extrusion process, before profile extrusion forming, profiles adapt to the extrusion degree level by level, and after extrusion forming, the required tenacity, strength, appearance and the like can be achieved.

Description

technical field [0001] The invention relates to the field of manufacturing and processing of aluminum profiles, in particular to a forming die for aluminum profiles and a forming method thereof. Background technique [0002] Aluminum profiles have a series of advantages. For example, aluminum profiles are less dense and lighter than other commonly used metals. Aluminum profiles are processed by hot and cold processes in the production process, and have strong corrosion resistance. Compared with other metals As far as the material is concerned, the aluminum profile has strong plasticity and good productivity, which has good advantages for production. Aluminum profiles have good casting performance and can be processed into aluminum profiles of different shapes. Compared with other metal materials, aluminum profiles , It has no metal pollution, no toxicity, and no volatile metals on the surface oxide layer. Therefore, the market demand for aluminum profiles is huge, and the re...
