Abstract
The utility model discloses a kind of spherical upset plate, comprise body (1), the lower surface of described body (1) is provided with ball recess (2), be provided with at the center of described body (1) run through body (1) draw material hole (3).The utility model have structure simple, manufacture advantage easy to process, adopting it when carrying out jumping-up to steel ingot blank, by drawing material hole, unnecessary blank being drawn, making up the generation of Shrinkage Problem, improve the quality of product.
Description
Technical field
The utility model relates to a kind of upsetting apparatus, particularly a kind of spherical upset plate.
Background technology
The existing spherical upset plate for forging, comprise a body, an end face of body is provided with ball recess, and structure upset plate can carry out upseting although it is so, but, there is following deficiency in the upset plate of this spline structure: 1. for the comparatively serious steel ingot blank of one end shrinkage cavity, when jumping-up, not only not easily eliminate this shrinkage cavity, but also shrinkage cavity can be made to extend internally, blank is finally caused to add man-hour, the phenomenon of scrapping; 2. adopt the steel ingot blank of the upset plate jumping-up of this structure, when carrying out follow-up pulling operation, shaping axis products, feeling resentful or shrinkage cavity easily appears in the end of its axis products, causes off quality.
Utility model content
The purpose of this utility model is just to provide a kind of spherical upset plate can eliminating blank shrinkage cavity.
The purpose of this utility model be by such technical scheme realize, a kind of spherical upset plate, comprises body, and the lower surface of described body is provided with ball recess, be provided with at the center of described body run through body draw material hole.
In order to form counter-pressure, described in draw material hole be up-small and down-big horn-like.
In order to prevent, when subsequent technique pulls out blank, occurring dead angle, have fillet in described bell-mouthed inner side, the radius of described fillet is 1/2nd of body central thickness.
For the ease of lifting, the upper surface of described body is provided with lifting portion, the outer wall in described lifting portion is provided with lifting groove.
Owing to have employed technique scheme, the utility model have structure simple, manufacture advantage easy to process, adopting it when carrying out jumping-up to steel ingot blank, by drawing material hole, unnecessary blank being drawn, making up the shrinkage cavity of blank, improve the quality of product.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of spherical upset plate, comprises body 1, and the lower surface of described body 1 is provided with ball recess 2, be provided with at the center of described body 1 run through body 1 draw material hole 3.In the utility model, the unnecessary blank produced can be drawn by drawing material hole 3, making up the shrinkage cavity of blank, improve quality in upsetting process.
Further, material hole 3 is drawn described in for up-small and down-big horn-like.Do the blank resistance that can make to draw within the scope of material hole 3 weeks like this to strengthen, form counter-pressure, seam is felt resentful or shrinkage cavity.
Wherein, bell-mouthed inner side has fillet 4, and the radius of described fillet 4 is 1/2nd of body 1 center thickness.Do like this and steel ingot blank can be prevented when follow-up pulling operation, occur dead angle between the protuberance of blank and steel ingot blank body, cause situation about cannot process.
For the ease of lifting, the upper surface of above-mentioned body 1 is provided with lifting portion 5, and the outer wall in described lifting portion 5 is provided with lifting groove 6.
Claims (4)
1. a spherical upset plate, comprises body (1), the lower surface of described body (1) is provided with ball recess (2), it is characterized in that: be provided with at the center of described body (1) run through body (1) draw material hole (3).
2. spherical upset plate as claimed in claim 1, is characterized in that: described in draw material hole (3) for up-small and down-big horn-like.
