Technical Field

The utility model belongs to the technical field of machining, especially, relate to a processing frock that general type clamp part takes shape.

Background

The clamp part structure is a plate, the whole body is bent to form a shape similar to omega, the upper half base is a plane, two holes are formed in the middle of the upper half base to serve as fixed positions, a large circle in the middle is used for placing a clamped part, and the lower side of the middle is reversely bent to form a small circle to play the roles of guiding and clamping. Often as a restraining tube and wire. The traditional manufacturing method is to cut the shape by laser and then to beat, bend and form the shape by a mould tire. The surface of the knocked-out clamp is easy to be knocked and damaged, because spring steel is often adopted, the bending forming process is extremely time-consuming, and the whole processing period of the part is too long. In terms of process, the front half-section process uses laser cutting, is efficient and accurate, but the back half-section process is disjointed by manual bending and cannot meet production requirements. Later, some special tool designs are adopted, and twice bending forming is adopted, but two molds correspond to one part generally, and the market requirements of multiple types and small batches cannot be met.
