Embodiment approach

[0038] In a further embodiment of the present invention, the concave arc surface matches the outer surface of the hub 5 , and the convex arc surface matches the inner surface of the hub 5 .

[0039] In a further embodiment of the present invention, several point-shaped inner stays 1 are included, and the convex arc surfaces of several dot-shaped inner stays 1 form a circular structure, and the circular structure formed by several dot-shaped inner stays 1 is combined with the two-shaped external pressure Piece 2 matches He Weicheng's ring structure. A number of dot-shaped inner struts 1 and two tooth-shaped outer pressure pieces 2 are arranged facing each other, and the inner drive mechanism 3 and the outer drive motor 4 work to make each pair of dot-shaped inner struts 1 and tooth-shaped outer pressure pieces 2 move closer together. , press fit, close to the inner wall and the outer wall of the hub 5, and the arc surface of the point-shaped inner support piece 1 and the tooth-...

Abstract

The invention discloses a floating block of a hub shaping die. The floating block comprises point-shaped internal bracing sheets and toothed external pressing sheets; a convex cambered surface is arranged on one side of each point-shaped internal bracing sheet; a plurality of convex bracing points are formed on each convex cambered surface; each toothed external pressing sheet is in a semicircular structure; concave cambered surfaces are arranged on the inner side surfaces of the semicircular structures, and are matched with the convex cambered surfaces; a plurality of pressing teeth are formed on each concave cambered surface, and are formed in the thickness direction of the corresponding semicircular structure; the convex bracing points and the pressing teeth are arrayed in a staggered manner. The floating block further comprises an internal driving mechanism and an external driving mechanism; the internal driving mechanism drives the point-shaped internal bracing sheets; the external driving mechanism drives the toothed external pressing sheets; and the point-shaped internal bracing sheets are fitted with or separated from the toothed external pressing sheets through the internal driving mechanism and the external driving mechanism. A hub is clamped through the point-shaped internal bracing sheets and the toothed external pressing sheets, and is stressed by the point-shaped internal bracing sheets and the toothed external pressing sheets at a deformation part, thereby achieving the shaping effect.

Description

technical field [0001] The invention relates to the technical field of wheel hub shaping, in particular to a wheel hub shaping mold. Background technique [0002] The heat treatment deformation of wheel hub products is large, and the deformation after heat treatment is eliminated by mechanical cutting to obtain the required size. This method will greatly increase the material usage of the product, the cost remains high, and the production efficiency is low. Contents of the invention [0003] In view of the above-mentioned problems, the object of the present invention is to provide a floating block of a wheel hub shaping mold. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A floating block of a wheel hub shaping mold, which includes: a point-shaped inner support piece, one side of the point-shaped inner support piece has a convex arc surface, and several convex support points are formed on the convex arc su...
