Description

Technical Field

[0001] The present invention relates to the technical field of vibration extrusion systems, and particularly to a hydraulic servo vibration extrusion system. Background Art

These application fields have extremely high requirements for the accuracy, stability, and efficiency of the vibration extrusion system.

[0003] The existing production process is that the extruder extrudes in place at one time. Due to the forced extrusion between the extrusion head and the product, lubrication cannot be achieved at the contact part between the extrusion head and the workpiece, resulting in a significant reduction in the service life of the extrusion head (the extrusion head is made of tungsten steel titanium plating material, with high manufacturing cost, leading to an increase in cost); in the new process, through the high-frequency vibration of the extrusion head, during the extrusion process, the extrusion vibrates at high frequency along the extrusion direction during the feeding process, enabling the lubricant to fully lubricate and cool the surface of the workpiece and the extrusion head, resulting in a high surface finish of the extruded workpiece and a significant increase in the service life of the extrusion head.
