Method for processing profiled core prints

Abstract

The embodiment of the invention discloses a method for processing profiled core prints, which comprises the following steps of: selecting die steel for blanking according to the diameter of a die; roughly lathing the excircle and thickness of the die according to the paper size; if the blank amount of the core print and the diffluent hole is larger than the blank set amount, marking off the shape and position of the diffluent hole and the core print of a top die by a marker, roughly machining by a plain-milling machine, conducting transverse alignment according to the excircle, semifinishing core print working tape by a numerical control milling machine, and processing the root of the core print and the diffluent hole according to the paper size; otherwise, conducting transverse alignment according to the excircle to directly process the core print working tape, and processing the root of the core print and the diffluent hole according to the paper size; carrying out heat treatment on the die, plainly grinding the upper plane and lower plane of the die, and conducting finish turning on the excircle of the core print according to the paper size; conducting transverse alignment according to the excircle, and conducting finish machining on the core print working tape by the numerical control milling machine according to the paper size; grinding and polishing the core print and assembling with a lower die and die cushion. The invention improves the processing quality of the core print, reduces the cost and shortens the processing time.

Description

technical field [0001] The invention relates to the technical field of mold processing, and more specifically, relates to a method for processing special-shaped cores. Background technique [0002] The production of hollow aluminum profiles is hot-extruded with a split mold, which is composed of an upper mold and a lower mold (such as figure 1 As shown: A represents the upper mold, B represents the lower mold), the dimensional accuracy and roughness of the upper mold core head work belt directly affect the dimensional accuracy of the profile hole, the smoothness of the inner surface and the service life of the mold. The work of the splitter mold core head is divided into a common core head work belt and a special-shaped core head work belt. The common core head work belt is such as a square core head work belt. The working belt of the mold is used as a benchmark, and is shaped according to the wall thickness of the profile with tool grinding. If the working belt of the spli...
