Abstract
The invention relates to an irregular ring forged piece tooling of a center mould sleeve of an automobile tire mould. The tooling is mainly applied to center mould sleeve forging of the automobile tire mould. The tooling comprises a core roller (1), an upsetting mould cushion (2) and a punch head (3). A peripheral middle part of the core roller (1) is arranged to form a truncated cone section (1.1), and a lower end of the core roller (1) is designed to a straight section (1.2); a step (2.1) is arranged on the periphery of the upsetting mould cushion (2), and an inner bore (2.2) of the upsetting mould cushion (2) is an inverse truncated conical bore; the punch head (3) is composed of an upper cylinder section (3.1), a middle truncated cone section (3.2) and a lower cylinder section (3.3) which are coaxially arranged to form a whole punch head from the top down; the diameter of the upper cylinder section (3.1) equals that of a small-diameter end of the middle truncated cone section (3.2), and the diameter of the lower cylinder section (3.3) equals that of a large-diameter end of the middle truncated cone section (3.2). The tooling facilitates stable rotation and rolling deformation of a workpiece.
Description
(1) technical field
The present invention relates to a kind of middle die sleeve, especially relate to a kind of middle die sleeve special-shaped ring forgeable piece tool of automobile tire mould.The middle die sleeve that is mainly used in automobile tire mould forges.Belong to the automobile tire mould technical field.
(2) background technology
Middle die sleeve is the important component part of automobile tire mould.Middle die sleeve structure as shown in Figure 1.Its internal diameter has a conical surface.Because the conical surface of this workpiece diameter, internal diameter two ends size is inconsistent, and the required materials variances in workpiece two ends is very big, and an end material is many, and an end material is few, therefore is unfavorable for workpiece smooth rotation and rolling deformation.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of middle die sleeve special-shaped ring forgeable piece tool that is beneficial to the automobile tire mould of workpiece smooth rotation and rolling deformation is provided.
The object of the present invention is achieved like this: a kind of middle die sleeve special-shaped ring forgeable piece tool of automobile tire mould, comprise core roller, jumping-up die-cushion and drift,
Be arranged to truncted cone section in the middle of the described core roller outer rim, core roller lower end is designed to a straight section,
The outer rim of described jumping-up die-cushion is provided with a step, and the endoporus of jumping-up die-cushion is a truncated inverted cone hole,
Described drift constitutes a drift integral body by coaxial setting of last shell portion, middle frustoconical section and following shell portion from top to bottom successively, the diameter of described upward shell portion is identical with the smaller diameter end diameter of middle frustoconical section, and the diameter of described shell portion down is identical with the larger diameter end diameter of middle frustoconical section.
Frock of the present invention helps workpiece smooth rotation and rolling deformation.

(5) specific embodiment
The middle die sleeve special-shaped ring forgeable piece tool of the automobile tire mould that the present invention relates to, the middle die sleeve structure of required processing as shown in Figure 1.Because its internal diameter has a conical surface,, see core roller Fig. 2 if, must process corresponding truncted cone section 1.1 in core roller 1 outer rim with its rolling comes out.Therefore when the blocking blank, must consider this factor.Designed a jumping-up die-cushion 2, as shown in Figure 3 for this reason.These jumping-up die-cushion 2 outer rims have a step 2.1, and endoporus 2.2 is a truncated inverted cone hole, during jumping-up blank are inserted in this jumping-up die-cushion 2 and carry out, and make the shape of blank as shown in the figure shown in 4.Carry out punching with special punch 3 as shown in Figure 5 again, the blank of finally making is seen Fig. 6.The described drift 3 of Fig. 5 constitutes a drift integral body by last shell portion 3.1, middle frustoconical section 3.2 and following shell portion 3.3 coaxial settings from top to bottom successively, the diameter of described upward shell portion 3.1 is identical with the smaller diameter end diameter of middle frustoconical section 3.2, and the diameter of described shell portion 3.3 down is identical with the larger diameter end diameter of middle frustoconical section 3.2.Climb roller for the prevention workpiece in the operation of rolling, designed a straight section 1.2 in core roller 1 lower end, be beneficial to workpiece smooth rotation and rolling deformation.Finally see forging drawing 7 for forging.
