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 key part in the extrusion granulator. It is extruded in the die through double-roll extrusion. Traditional extrusion molds are usually formed by casting and hot extrusion, but the quality of the molds processed in this way is unstable, with poor tensile and bending properties, easy to crack, and has a short service life. fall off, and it is less efficient and costly when grinding the die hole. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects of the prior art, and to provide an extrusion die processing technology with long service life and easy falling off. [0004] In order to solve the above-mentioned technical problems, the technical scheme of the present invention is: a processing technology of an extrusion die, which is used for processing the...
