Embodiment Construction

[0014] The technical solutions of the present invention are specifically described below through several examples, but the present invention is not limited to the following examples.

[0015] refer to figure 1 , 2 , an aluminum alloy bar mold, the deflector is removed, the mold body is directly in contact with the aluminum rod for extrusion, the production and process have been changed accordingly, by controlling the extrusion speed and the temperature of the aluminum rod Wait for a series of parameters to control the layering phenomenon at the end of the bar; remove the transition area of ​​the mold sleeve, let the mold directly expose to the outside for extrusion, and through such rectification, the layering phenomenon of the bar is basically solved.

[0016] An aluminum alloy bar mold, the guide plate 1 is removed, the transition area 6 of the mold cover 2 is removed, and a rear mold pad 5 is added, including the mold sleeve 2, the mold body 3, the mold pad 4, and the rear...

Abstract

The invention relates to an aluminum alloy bar die, which belongs to the aluminum alloy bar die technical field. The aluminum alloy bar die is characterized in that: the aluminum alloy bar die comprises a die sleeve (2), a die body (3), a die cushion (4), and a rear die cushion (5), wherein, the die sleeve (2) is orderly sleeved with the die body (3), the die cushion (4) and the rear die cushion (5); the inner diameters of a channel (8), a channel (9) and a channel (10) in the die body (3), the die cushion (4) and the rear die cushion (5) are orderly enlarged; the inner diameter of the channel (8) in the die body (3) is more than the diameter of a channel (11) in the die body (3) which is used for an aluminum alloy bar to pass through; the upper part of the die body (3) is provided with a lug boss (12); and an upper plane of the lug boss (12) of the die body (3) is coincident with an upper plane of the die sleeve (2) into the same plane. The aluminum alloy bar die eliminates the stratification defect of an internal structure of an extruded bar, residue materials accumulated in internal channels of the die are reduced, the finished product rate is improved to more than 65-70 percent, and the stratification phenomenon of the bar is basically solved.

Description

1. Technical field [0001] The invention relates to an aluminum alloy rod die, which belongs to the technical field of aluminum alloy rod dies. 2. Background technology [0002] The mold used in the production of aluminum alloy rods is designed according to the conventional design method. The mold is composed of mold casing 2, deflector 1, mold body 3 and mold pad 4, as shown on the right figure 1 shown. This kind of mold structure is barely enough for soft alloys like 6063 or 6061 to produce some small-diameter bars. At present, the specifications of the bars produced are relatively large, and most of them are superhard alloys like 2xxx and 7xxx. Especially when exporting abroad, the quality must be strictly controlled. [0003] There is a big problem in the use of this kind of mold, which is easy to cause layered defects in the internal structure of the extruded rod. The residual material accumulated in the deflector internal channel 7 can cause stratification at the fro...
