Description

Technical Field

[0002] Extrusion dies are mainly suitable for the processing and manufacturing of metal workpieces, which refers to the dislocation movement, dislocation rearrangement, and dynamic recrystallization that occur when the workpiece passes through the die, and then the deformed rough metal is converted into fine metal, which is used to improve the performance of the metal material; in the extrusion deformation process of the metal workpiece, the extrusion pressure of the metal part will generate a large extrusion pressure on the circulating extrusion die, and then the die is easily bent or broken. Therefore, during the use of the circulating extrusion die, a die sleeve is generally used to position and protect the die. When the existing die sleeve is used in conjunction with the die for processing, the die is generally fixed inside the die sleeve by bolts through and screwed together. Since this installation method does not have any docking and limiting structure during the installation process, it makes it difficult to align the screw holes, and it is also necessary to tighten the bolts with the help of corresponding tools during installation, which makes it more troublesome to fix. For this reason, we propose a die sleeve processing and fixing mechanism for an extrusion die. Utility Model Content
