Description

Orthopedic fixture for metal parts

Technical Field

The utility model relates to the technical field of orthopedic clamps, in particular to an orthopedic clamp for metal parts.

Background

Currently, the shape correction of known parts is mainly divided into cold correction and hot correction. The cold straightening mainly enables the parts to generate plastic deformation under the action of external force through a specific fixture at normal temperature so as to achieve irreversible morphological change and meet the design requirements of the parts; the hot straightening is to place the parts in a heating furnace to heat to a specific temperature according to the properties of different materials of the parts, then take out the parts, and shape the parts under the action of external force similar to cold straightening so as to achieve the orthopedic requirements of the parts. However, both cold straightening and hot straightening have limitations, for example, cold straightening is performed at normal temperature, so that over-straightening is very easy to generate, local cracking and the like of parts are caused, the rejection rate of the parts is very high, the parts are heated wholly or locally to achieve a relatively easy plastic form, but in the heating process, the parts are often subjected to uncontrolled reverse development, the deformation amplitude is increased, and the correction difficulty is increased, so that uncontrollable factors exist in both cold straightening and hot straightening.
