Embodiment Construction

[0023] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0024] The invention provides a method for processing an extrusion die, comprising the steps of:

[0025] S1. Pre-processing: Pre-processing includes blanking, rough turning and drilling in sequence, so as to process the outer circle, assembly surface, diversion hole and seam of the upper and lower dies. Rough turning mainly refers to turning out the outer circle, assembly surface and seam of the mold on the CNC lathe or ordinary lathe according to the requirements of the design drawings. Drilling is the use of machine tools to process the process holes and threaded holes of the upper and lower dies.

[0026] S2. CNC rough milling: including rough milling of the upper mold and rough milling of the lower mold. The rough milling of the upper mold is mainly based on the requirements of the drawing on ...

Abstract

The invention discloses a machining method of an extrusion die. The machining method includes the following steps of S1, pre-treatment, S2, CNC rough milling including rough milling of an upper die and rough milling of a lower die, S3, heat treatment, S4, CNC finish milling including finish milling of the upper die and finish milling of the lower die, S5, surface grinding, S6, grinding adopting asand paper to grind the rough surface of a flow dividing hole to be smooth for reducing the action of the friction force between the flow dividing hole and an aluminum rod during extrusion of aluminumprofiles, S7, polishing, S8, tool grinding, S9, fine turning and S10, inspection and storage. According to the machining method, the production cycle of the extrusion die is greatly shortened, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold production, in particular to an extrusion mold processing method. Background technique [0002] With the rapid development of industry, the application of aluminum profiles is becoming wider and wider. The extrusion dies used in the processing of aluminum profiles are particularly important. In the existing extrusion die processing technology, the method of EDM is mainly used to process the end face of the die working belt and the empty knife. The working belt on the back, the rough working belt is also used as a positioning reference for subsequent processing; and then the pure copper tool electrode is processed by wire electric discharge cutting, the shape of the tool electrode is consistent with the groove of the extrusion die The shape of the groove is consistent; the tool electrode is used to perform electric discharge machining on the end surface of the workpiece, and the groove of the extrus...
