Abstract

The invention provides a machining process for an extrusion die. The machining process is used for machining the extrusion die sleeved on a roll shaft of a granulator. A die blank with die holes is subjected to thermal treatment and finish machining, and each die hole is subjected to extrusion and grinding treatment. The thermally treated extrusion die has strong strength, cannot be cracked after being extruded for a long time, and is long in service life; the die holes are high in compressive resistance and bending resistance, and cannot be deformed by extrusion; after the finish machining, the extrusion die can rotate stably, and the yield is high; in addition, the grinding cost of the extrusion mode is low, and two die blanks can be ground by once extrusion, so that the grinding efficiency is high; and the die holes of the ground die blanks are low in roughness, and extruded products are easy to de-mold.

Description

technical field [0001] The invention relates to die processing, in particular to a processing technology of an extrusion die. Background technique [0002] The extrusion die is a relatively critical part in the extrusion granulator. It is extruded in the die by twin-roll extrusion. Traditional extrusion dies are usually formed by casting and hot extrusion, but the molds processed in this way are of unstable quality, poor tensile and bending resistance, easy to crack and short service life, poor smoothness of the die hole, and difficult for materials to be formed after forming. Falling off, and the efficiency is low when grinding the die hole, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a long service life and easy-to-fall extrusion die processing technology. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present inven...
