Powder spraying, marking and blank cutting method for aluminum alloy components with ribs

Abstract

A powder spraying, marking and blank cutting method for aluminum alloy components with ribs includes 1, utilizing computer drawing software to draw graphics of components to be machined on the polished side of an aluminum alloy component with the ribs, and arranging seam lines to divide the aluminum alloy component with the ribs into a plurality of small plates; 2, drawing a locating datum line; 3, drawing a positioning angle square datum line; 4, drawing a first branch datum line and a second branch datum line; 5, utilizing a digital controlled cutting machine to spray powder on the polished side of the aluminum alloy component with the ribs; 6, testing the positions of the ribs; 7, cutting. By the aid of the method, the ribs are flushed when the aluminum alloy component with the ribs is connected with an adjacent one, the aluminum alloy component with the ribs can be blanked and cut sequentially, cutting accuracy is improved, producing efficiency is improved exponentially, production cost is reduced, labor intensity of cutting staff is reduced, production security is enhanced, and great promotion value is provided.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a powder-spraying, scribing, blanking and cutting method for an aluminum alloy ribbed plate part. technical background [0002] A certain type of ship is a high-tech product under construction, and the superstructure sections of the ship are all made of aluminum alloy ribbed plate materials, involving more than a dozen sections. The feature of the aluminum alloy ribbed plate is that the aluminum plate and the T-shaped rib are combined into one, and one side is a T-shaped rib line and the other side is a smooth surface. In the construction process of the first ship, due to the special nature of conventional CNC cutting (the ribs of the parts with tube plates must be aligned with the ribs of adjacent parts), only manual marking can be used. The method of blanking cutting is very inefficient. Due to the particularity that the assembly of aluminum alloy ribbed plate parts need...

AI Technical Summary

Problems solved by technology

From the analysis of the existing materials: first, the aluminum alloy sheet is 3mm to 8mm thin, and the material is characterized by a large expansion coefficient, which will produce different forms of deformation during the cutting process; second, the aluminum alloy ribbed sheet is not integrated with the reinforcing rib Suitable for CNC cutting

Since the drawing of rib lines on the reverse side cannot be seen during the part turning (smooth surface) blanking process, the marking accuracy is difficult to control

The third is that the ribs of the ribbed plate itself have curvature, which makes the ribs not aligned after the parts are blanked.

The fourth is the curvature linear longitudinal perforation of the ribbed plate, T-row holes, and many pipe holes, which affect the blanking cutting accuracy and production nodes of the ribbed plate parts
