Excess material removal technology for alloy die casting piece

Abstract

The invention discloses an excess material removal technology for an alloy die casting piece. The excess material removal technology comprises the following steps that a to-be-machined workpiece is fixed to an electromagnet clamp, and the to-be-machined workpiece is adjusted to the preset position of a workbench; and laser cutting equipment is used for conducting laser cutting treatment on rough edges and a hole-shaped structure of the treated workpiece, rough materials on the periphery of the to-be-machined workpiece and excess materials in the hole-shaped structure are removed, and pre-machining is conducted on the to-be-machined workpiece. The to-be-machined workpiece is fixed through the electromagnet clamp, then the laser cutting equipment is used for conducting laser cutting treatment on the rough edges and the hole-shaped structure of the treated workpiece, the rough materials on the periphery of the to-be-machined workpiece and the excess materials in the hole-shaped structureare removed, then rapid cutting of the excess materials of the alloy die casting piece can be achieved, and accordingly the alloy die casting piece excess material removal efficiency is improved; andmeanwhile, the electromagnet clamp can rapidly and effectively fix the workpiece, product fixing through a complex die structure is not needed, and the workpiece installing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of residual material removal of die-casting parts, in particular to a process for removing residual material of alloy die-casting parts. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. [0003] Some existing thin-walled parts, such as the middle frame of mobile phones, are widely manufactured by die-casting molding process, which has low processing cost and high production efficiency. After the die-casting of the middle frame of the mobile phone, it is necessary to remove the material head ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that two sets of dies (a rough die and a fine die) are required to remove the remaining material by using a punching die and a punching machine. The processing cost is high, and the cutting efficiency is poor. It is difficult to adapt to the increasing workload of the existing middle frame of the mobile phone.
