Abstract

The invention discloses a rough and fine shaping integrated jig for a rotor. The jig comprises a rough shaping die plate and a fine shaping die holder, wherein the rough shaping die plate and the fine shaping die holder are provided with a rough shaping rotor die hole and a fine shaping rotor die hole respectively, the rough shaping die plate is arranged on the fine shaping die holder, the rough shaping rotor die hole corresponds to the fine shaping rotor die hole, and the fine shaping rotor die hole corresponds to the rough shaping rotor die hole. The rough shaping die plate and the fine shaping die holder are fixed together through screws. As the rough shaping template is additionally arranged, the shaping precision is improved, and the shaping quality of the rotor is ensured. As the fine shaping die holder is improved, a protruding piece is improved to be of the plug-in type structure from an original structure integrally formed with the fine shaping die holder, the protruding piece is an easy-to-damage piece and can be replaced in time after being abraded, so that the service life of the fine shaping die holder is prolonged, and the production and machining cost is reduced.

Description

technical field [0001] The invention relates to a shaping jig, in particular to a shaping jig for a variable valve VVT ​​rotor of an engine. Background technique [0002] Among the existing shaping jigs, the shaping jig for the VVT ​​rotor of the engine variable valve adopts the one-step shaping mode. Since there is no pre-shaping, the one-step shaping mode is directly used, and the shaping quality of the rotor cannot be guaranteed. In addition, the convex parts in the plastic mold are integrally formed with the plastic mold base. The convex parts are vulnerable parts. After the convex parts are worn out, they cannot be replaced, and the plastic mold needs to be scrapped. The usage of the plastic mold is large, resulting in processing costs. higher. For example, the patent document with publication (announcement) number CN104959614A, Shaping method and shaping mold for iron-based powder metallurgy rotor or gear products, discloses the following content: The invention disclo...
