Embodiment Construction

[0016] Such as figure 1 The high-reinforced open-type material of the present invention shown has a mountain-shaped cross-section, and the height of the ribs is relatively large, which belongs to the high-reinforced open-type parts.

[0017] 1. The mold used to produce the above-shaped high-strength opening type material:

[0018] Such as Figure 7 As shown, the false splitter mold with an arched splitter bridge is mainly composed of an upper mold 1 and a lower mold 2 .

[0019] Such as figure 2 , 3 , 4, three distribution holes 11 are distributed on the upper mold 1, and two distribution bridges 12 are correspondingly provided, and the lower bottom surface of each distribution bridge 12 is an arc surface 13 that arches upward from the center.

[0020] Such as Figure 5 , 6 As shown, the lower mold 2 is provided with a chevron-shaped welding chamber 21 , a working belt 22 and an empty knife 23 matched with the chevron-shaped flow opening 11 .

[0021] 2. Taking 6063T5 ...

Abstract

A production method of a high-rib opening section bar belongs to the field of section bar machining, particularly a production method of a high-rib opening aluminium alloy section bar and a mold technology. According to the production method, extrusion production is carried out after an aluminium alloy bar subjected to homogenization treatment, an extrusion container and a mold are respectively heated; and the production method is characterized in that a pre-running mold with an arched bypassing bridge is used for production in the extrusion process. The production method has the advantages of being capable of well solving the problem that a cantilever part of the mold is crushed and cracks prematurely in the extrusion process, well prolonging the service life of the mold and particularly suitable for extruding the high-rib opening section bar.

Description

technical field [0001] The invention belongs to the field of profile processing, in particular to a production method of high-rib open aluminum alloy profiles and mold technology. Background technique [0002] Because of its series of advantages, aluminum alloy profiles are used in many fields, and the market demand is large, especially for high-reinforced open profiles. At present, diversion dies are used for the production of open profiles in the market, but in actual production, it is found that the production effect of diversion dies for high-reinforced open profiles is not good. The main reason is that the cantilever part of the diversion die is too long. The force of the cantilever part is complicated, and the cantilever part is easy to break and collapse), resulting in early failure of the mold. Contents of the invention [0003] The purpose of the present invention is to provide a production method of a high-rib open-type material to solve the problem that the can...
