A New Approach to Precision Cropping with Radial Forging
This paper presents a new approach to precision cropping with radial forging, it skillfully utilizes the stress and strain concentration effect of the prefabricated V-shaped notch and the principle of the radial-forging machine to achieve the regular fracture of metal bar. The basic working principle of the new radial-forging cropping method is discussed in detail. Moreover, the distribution of the radial displacement loads is discussed in detail, and the loading rules are clearly explained under the conditions of the single cropping die, two cropping dies, three cropping dies and four cropping dies, as well as the radial-forging loading sequence. The model and equation of the movement with the radial-forging are established, the feasibility analysis of the radial-forging cropping method is carried out, which is in agreement with the experimental results.
