Title Design of the Stamping Process and the
die for the spring hook
Abstract
This paper analyzes the technical characteristics of the spring hook such as configuration dimension precision and the capability of the raw materials.There are including the difficulties of this production in the molding,studying out the technics of the progressive die,making sure the layout project and the die general structure. The progressive die could complete thirteen processes that include punching, blanking, bending and so on.It has finished all needed technical count,including the knife-edge of the mold, the force of ench process, punch technical force of the all process and the stress center of the mold.It summarizes the method of designing this mold.It introduces the design and manufacture of the punch, the die, the stripping device, the pushing device, and the blanking holders in details. And it also expatiates theworking process of the die, the coordination about each motion of figurations. Besides it has a section about equipment choosing and proofreading.
