Abstract

The invention discloses polylactic acid blank forging and pressing strengthening equipment. A polylactic acid blank is processed further, is deformed under the effect of applied pressure, and is oriented, and then the strength of a finally obtained sectional material is improved. The obtained sectional material can be used in the field of medicine, and is used for preparing bone screws for fixing fractured bones after a fracture.

Description

technical field [0001] The invention relates to forging and pressing forming equipment, in particular to forging and pressing strengthening equipment for polylactic acid. Background technique [0002] As a degradable material, polylactic acid has good tissue compatibility, so it has a wide range of uses in medicine. However, polylactic acid prepared by conventional methods has limited its application because of its low strength and retention. [0003] Since polylactic acid can be processed and formed by self-reinforcement technology, it is not necessary to introduce a reinforcement phase, that is, the interface between the reinforcement phase and the collective chemical structure will not be increased. Therefore, it is important to study polylactic acid materials to improve the strength of polylactic acid through self-reinforcement technology. An ideal method as an internal fixation device for fractures. The self-reinforcing technologies of polylactic acid mainly include fi...
