specific Embodiment 1

[0038] Such as figure 2 , image 3 and Figure 4 The mold structure of the large double-hole pipe profile with transverse ribs shown is used to make the mold of WYY0770 large double-hole pipe with transverse ribs. It is divided into upper mold 1 and lower mold 2, that is, a two-piece set. The upper mold 1 and the lower mold 2 are matched. The specification of the mold is φ800*500mm. The thickness of the upper mold 1 is larger than that of the lower mold 2. The upper mold 1 has a thickness of 260 mm, and the lower mold 2 has a thickness of 240 mm. Six distribution holes 1-1 are evenly distributed around the upper mold 1. The lateral width and longitudinal width of the distribution holes 1-1 are The amount is proportional to the size of the large double-hole pipe profile with transverse ribs, (see figure 2The widening part of the central distribution hole 3), the X axis represents the horizontal direction, and the Y axis represents the vertical direction. The angle is 12°,...

specific Embodiment 2

[0058] The characteristics of this embodiment are: the lateral width of the distribution hole is 23°, and the width is 150mm; the Y-axis of the distribution hole is laterally wide, the width is 12°, and the width At 800mm, other features are the same as those in Embodiment 1.

specific Embodiment 3

[0059] The characteristics of this embodiment are: the X-axis of the distribution hole is longitudinally widened, the widening angle is 23°, and the widening amount is 200mm; the Y-axis of the said distribution hole is horizontally widened, and the widening angle is 12° , the amount of wide expansion is 150mm, and other characteristics are identical with specific embodiment 1.

Abstract

The invention discloses a mold structure of a large double-hole pipe profile with horizontal reinforcing ribs and a processing method of the large double-hole pipe profile. The mold structure is characterized in that a broadening and flow-distributing combined mold is formed by adopting an upper mold and a lower mold; the periphery of the upper mold is provided with six flow distributing holes which are uniformly distributed, and the middle part of the upper mold has two horizontal and serial stepped type flow-distributing holes; the flow-distributing holes are horizontally broadened, the broadening angle is 23 degrees, and the broadening amount is between 150-200mm; a welding chamber of the lower mold is externally connected with a circle with the diameter being 600mm and the depth of the welding chamber is 40mm; the mold is made of a 4Cr5MoSiV1 hot-work mold, a CAD / CAM / CAE full-automatic processing method is adopted, the mold structure of the double-hole pipe profile is accurately designed, and the mold is treated by processes such as high-temperature quenching, tempering and nitridation, so that the improvement on the hardness value of the surface of the mold is ensured. The mold disclosed by the invention has the advantages that the structure is simple and reasonable, the welding quality in processing the pipe material is guaranteed, the high-quality large double-hole pipe profile with the horizontal reinforcing ribs can be processed, the manufacturing difficulty of the mold is reduced, and the service life of the mold is also prolonged.

Description

technical field [0001] The invention relates to a processing mold and a processing technology of a structural section material, in particular to a mold structure and a processing method of a large double-hole pipe section material with transverse reinforcing ribs. Background technique [0002] There are more than 100 types of aluminum alloy structural extrusion profiles for green buildings. Most of the existing aluminum alloy extrusion profiles for green buildings do not require machining, but are directly used as parts and related parts. Therefore, the dimensional accuracy and shape Bit precision requirements are very high. The alloy grades of structural profiles are mostly medium-strength aluminum alloys such as 6061, 6005A, and 6082, as well as high-strength and high-toughness aluminum alloys such as 2xxx, 5xxx, and 7xxx. Extruded profiles of aluminum alloy building structures require high mechanical properties, σ b ≥290MPa, excellent comprehensive properties such as we...
