Problems solved by technology

At present, it has been used in the drawing of wire rods, pipes and special-shaped materials, punching, shearing, fine pressing, rolling and other processing processes of metal materials. The excitation methods used are mainly power ultrasonic vibration and mechanical vibration. , both have very obvious limitations, such as limited vibration direction, limited output power, small excitation force, difficult to adjust frequency and amplitude

Abstract

The invention belongs to the technical field of hot forming dies and relates to a multi-module multi-directional high frequency vibration hot forming die comprising an upper die, a lower die and a guide rod. The guide rod guides relative motion of the upper and lower dies. A hydraulic vibration exciter capable of vibrating under high frequency in multiple directions is disposed below the lower die. The multi-module multi-directional high frequency vibration hot forming die has the advantages that flow stress borne by metal material during hot forming of work pieces is low, resistance of metal flow into a female die is low, load is stable and extrusion force is small.

Description

technical field [0001] The invention belongs to the technical field of thermoforming dies, in particular to a multi-module multi-directional high-frequency vibration thermoforming die. Background technique [0002] The processing method of hot forming is to use the characteristics of high plasticity and small deformation resistance of metal materials at high temperatures, to force the metal blank to produce plastic flow through the gap between the punch and the die or the die with a strong pressure and a certain speed. Extrude hollow or solid parts whose section is smaller than that of the blank. The parts processed by the thermoforming process have the characteristics of continuous metal streamline, high strength, strong plasticity, high forming precision, small friction in the forming stroke, more uniform heat transfer, strong mechanical properties, etc., and the processing process is safer. , with better economic and social benefits. [0003] Since F. Blaha and B. Lange...
