Vertical mechanical vibrating hydraulic extruder

Abstract

The invention discloses a vertical mechanical vibrating hydraulic extruder, which comprises four pillars, wherein the two ends of the four pillars are respectively connected with an upper cross beam and a base, a first hydraulic cylinder is fixed on the upper cross beam, the end part of a piston rod of the first hydraulic cylinder is matched with a first sliding rail by a first slide block, a second hydraulic cylinder is fixed at the lower part of the first slide block, a mold is connected to the lower part of the second hydraulic cylinder, a vibrating mechanism is fixed in a base and connected with the bottom of a workbench, a clamping mechanism is arranged at the upper part of the workbench, a second slide block connected with the workbench is matched with a second sliding rail, the second sliding rail is connected to the base, the clamping mechanism clamps workpieces, and the vibrating mechanism drives the workbench to vibrate. According to the invention, axial feeding is separated from a vibrating process, therefore, the extruder is easy to control; the structure of the hydraulic cylinder is simplified, and the seal requirements of the hydraulic cylinder are reduced; and the extruder is compact in overall structure, and more stable and reliable in the extrusion process.

Description

technical field [0001] The invention belongs to the technical field of mechanical forming equipment presses, and in particular relates to a vertical mechanical vibration hydraulic extrusion machine. Background technique [0002] Cold extrusion molding is a precision plastic volume forming technology. Cold extrusion refers to putting the metal blank into the mold or the clamping mechanism in a cold state, and under the action of strong pressure and a certain speed, the workpiece blank is formed in the mold cavity, so as to obtain the required size and mechanical strength. performance extrusions. Cold extrusion processing is to control the flow of metal through the mold, so as to realize the large transfer of metal volume to form parts. Cold extrusion molding has been widely used in fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, military and other industrial sectors, and has become one of the indispensable and important pro...

AI Technical Summary

Problems solved by technology

Since the hydraulic press adopts a unified pump station for hydraulic supply, this makes the axial feed speed of the hydraulic cylinder affect the vibration control, and there is a disadvantage that the vibration cannot be controlled separately
