Description

Wheel rim body expanding shaping mould

Technical field

The utility model relates to a kind of shaping mould, and particularly a kind of wheel rim body expanding shaping mould belongs to technical field of engineering machinery.

Background technology

The wheel rim moulding is the key link that the engineering truck wheel is produced; Its forming process comprises blank, volume circle, butt welding down, scrapes tens procedures such as slag, calendering weld seam, crop, bistrique, crowded limit, cooling, enlarging, a roller moulding, two roller moulding, three-roll formation, expanding, valve hole, removal valve port burr, crowded wheel rim; And expanding is the important procedure of wheel rim moulding, is the critical process of decision rim size and quality.

Present wheel rim expanding shaping mould; Its Shaping Module is generally overall structure, need change different module during the different cultivars shaping, because the characteristics that the engineering truck wheel is produced are small lot, many kinds; Therefore, the shaping mould of existing structure can not satisfy the requirement of production.Simultaneously, owing in the shaping process, constantly rub between cone and the module, shortened the service life of mould.In addition, last lower cone is in the shaping process, and constantly vibration makes lower cone loosening easily, influences expansion amount, reduces the expanding plastic precision.

The utility model content

The utility model provides a kind of wheel rim body expanding shaping mould, and this shaping mould has convenient, long service life, the characteristics that the expanding precision is high changed.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The wheel rim body expanding shaping mould that the utility model provides comprises upper die and lower die, and this patrix comprises cope match-plate pattern and upper cone, and this counterdie comprises lower bolster and lower cone, and said cope match-plate pattern is connected through guide pillar with lower bolster; Between said upper cone top and the cope match-plate pattern, be equipped with copper sheathing between lower cone bottom and the lower bolster, cope match-plate pattern bottom, lower bolster top all are fixed with float plate, and this float plate is set on the said copper sheathing, is fixed with backing plate and guide plate on the said float plate successively; Said float plate is interior, upward the lower cone conical surface is arranged with inner module outward, and this inner module is arranged with the external mold piece outward.

Wherein, said inner module inner surface is provided with draw runner.

Wherein, the end of said upper/lower cone is provided with patrix set screw, counterdie set screw.

Further, the said lower cone of going up is made up of 12 cones, and each piece cone is respectively for an inner module, outer module of each inner module correspondence.

The wheel rim body expanding shaping mould that the utility model provides is designed to inside and outside two modules with former integral module, and different product only need be changed outer module, outer module is fixed on the inner module get final product; Therefore, make things convenient for organization of production, prolong the service life of mould simultaneously.Simultaneously, the utility model is provided with draw runner between last lower cone and inner module, after draw runner wearing and tearing, can in time change, thereby prolong service life of inner module and mould.In addition, the utility model is provided with set screw in the end of last lower cone, and the height of lower cone is gone up in convenient adjustment, controls total expanding amount, has improved the expanding precision.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of the utility model wheel rim body expanding shaping mould.

The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not paying creative work belongs to the scope that the utility model is protected.

As shown in Figure 1; The wheel rim body expanding shaping mould that the utility model provides comprises upper die and lower die, and this patrix comprises cope match-plate pattern 11 and upper cone 12; This counterdie comprises lower bolster 21 and lower cone 22, and said cope match-plate pattern 11 links together through guide pillar 30 with lower bolster 21; Between said upper cone 12 tops and the cope match-plate pattern 11, be equipped with copper sheathing 30 between lower cone 22 bottoms and the lower bolster 21, upper cone 12 can slide with lower cone 22 relative copper sheathings 30; Cope match-plate pattern 11 bottoms, lower bolster 21 tops all are fixed with float plate 40, and this float plate 40 is set on the said copper sheathing 30, are fixed with backing plate 50 and guide plate 60 on the said float plate 40 successively; Said float plate 40 interior, last

lower cone

12,22 conical surfaces are arranged with inner module 70 outward; These inner module 70 outer external mold pieces 80 that are arranged with; Inner module 70 and outer module 80 splits design when the wheel rim of different product or specification is carried out shaping, only need the outer module 80 of replacing to get final product.

Said inner module 70 inner surfaces are provided with draw runner 90, prevent the wearing and tearing of 12,22 pairs of inner module 70 inner surfaces of upper/lower cone; When draw runner 90 serious wear, in time change, guarantee plastic precision.

The said

lower cone

12,22 of going up is made up of 12 cones, and inner module 70 is 12 with outer module 80, and correspondingly draw runner 90 also is 12,

lower cone

12,22 respectively corresponding inner modules 70 on each piece, each inner module 70 corresponding outer module 80.To realize the expanding motion;

The utility model course of work is following:

Under the effect of hydraulic press pressure; Upper/

lower cone

12,22 slides to the middle part; The pushed inner module 70 of upper/

lower cone

12,22 is done entad centrifugal motion along guide plate 60; Disperse motion thereby change movement in vertical direction into horizontal direction, realize the purpose of expanding moulding, the expanding amount by and Stroke Control.
