Abstract

The invention discloses a radial breaking high-efficiency precise low-stress discharging machine, and belongs to the technical field of intelligent manufacturing. The radial breaking high-efficiency precise low-stress discharging machine comprises four groups of discharging units symmetrically distributed in the circumferential direction, each group of discharging units includes a first hydrauliccylinder, a second hydraulic cylinder, discharging fixtures disposed at the end parts of piston rods of the first hydraulic cylinder and the second hydraulic cylinder, a third hydraulic cylinder, a fourth hydraulic cylinder and thrust hammers separately fixed to the end parts of piston rods of the third hydraulic cylinder and the fourth hydraulic cylinder; the discharging fixtures and the thrust hammers are oppositely arranged; when a bar material is subjected to breaking, after the thrust hammers abut against the bar material, the discharging fixtures apply loads to both ends of a V-shaped groove of the bar material, and alternating force is generated at the V-shaped groove. Under the force, cracks are formed at the V-shaped groove, it is ensured that the cross section of the tip end of the V-shaped groove gradually expands toward the center of the circle in a circumference mode, and the quality and flatness of the cross section of the bar material are improved by changing the loadingmode of the bar material.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a high-efficiency and precise low-stress blanking machine for radial breaking. Background technique [0002] Low-stress blanking is to apply crack technology to bar blanking. First, a circumferential V-shaped groove is artificially prefabricated on the surface of the bar, and then a certain external force is applied to the bar with the circumferential V-shaped groove surface. Make it dynamically separate in the form of low stress brittle fracture. It utilizes the notch effect and bending effect of the circumferential V-groove to achieve brittle fracture of materials at low stress levels. At present, scholars have conducted some research on low-stress bending blanking technology from the aspects of stress concentration, mechanism design, and fracture morphology. However, key core technologies such as the material separation mechanism of low-stress bending blank...
