Abstract
The utility model relates to a super-thick hemispheric die which comprises an upper die and a lower die, wherein the upper die is of a hemispheric structure, the lower die is an annular support body, an oblique surface is arranged on the upper edge of the inner wall of the lower die, the included angle alpha between the oblique surface and the axis of the lower die is from 30 degrees to 45 degrees, and the upper edge of the oblique surface and the lower edge of the oblique surface are both in circular arc transition. The super-thick hemispheric die is simple in structure. Due to the improvement of the upper edge of the inner wall of the lower die, smooth drawing is guaranteed, plates are protected, and molding efficiency is improved at the same time. The super-thick hemispheric die is reasonable in structure, easy to manufacture and machine, good in using effect, and popularized and applied easily.
Description
Technical field
The utility model relates to the end socket die for manufacturing of metal production industry, is specifically related to a kind of super thick hemisphere mould.
Background technology
The large thick-wall hemispherical head is one of strength member of the equipment such as chemical industry, nuclear power, and the control of its size, shape and wall thickness is the key of drawing process success or failure.Solve its stretch forming problem, of great advantage to the preparation of correctly designing mould and blank.
Summary of the invention
The utility model provides a kind of super thick hemisphere mould for the problem and shortage that exists about large thick-wall hemisphere forming technique in prior art.
Technical scheme: a kind of super thick hemisphere mould, comprise mold (punch) and bed die (die), mold is the semicircle ball shape structure, counterdie is annular support, the inwall top edge of counterdie arranges the inclined plane, the scope of this inclined plane and counterdie axle center angle α is 30 °≤α≤45 °, and the upper and lower rib on this inclined-plane is arc transition respectively.
The scope of inclined plane and counterdie axle center angle α is preferably 35 °≤α≤42 °
Beneficial effect: the utility model mould structure is simple, can guarantee that the smooth and easy of drawing process carries out after bed die inwall top edge is improved, and sheet material is had protective effect, can improve shaping efficiency simultaneously; It is rational in infrastructure, easily makes processing, and result of use is good, is beneficial to very much promotion and implementation.
