Abstract
The utility model relates to a cold pressing cone melon petal mold which comprises a cone part and a straight side part. The cone angle the cone part is in 60 degrees. The straight side portion is converged from outside to inside to form a converged opening. The inclined included angle of a side with the converged opening and the axis is in 6 degrees. The cone part and the straight side part are in a circular arc transition. The radius of the circular arc is 171mm. A notch is formed in an end port of the straight side part. A bottom surface of the notch is in parallel with a bottom side. A notch is formed in an end port of the cone part. The bottom surface of the notch is perpendicular to the bottom side. According to the cold pressing cone melon petal mold, the prior cone melon petal hot pressing to cold pressing is changed, and therefore energy is saved and production delivery time is shortened. The prior integral mold design and the hot pressing melon petal mold design are changed and design of different recurrent magnitudes chosen for different portions of the cold pressing cone melon petal mold is adopted. According to the deformation character of the cold pressing cone body, mold manufacturing method of combination of radius deep digging and inward inclination of the straight side is adopted. The cold pressing cone melon petal mold is reasonable in structure, good in using effect, high in once-forming ration, capable of reducing workload of a secondary process and favorable for application and popularization.
Description
Technical field
The utility model relates to the end-sealing die manufacturing technology of metal production industry, is specifically related to a kind of cone melon lobe mould of colding pressing.
Background technology
Existing taper die mostly is hot-forming, and process costs is higher, and process is complicated, each step required precision is high, the large problem of deformation of products amount after the demoulding can occur, and existingly be applicable to the cold moudling of being done for of hot-forming taper die, special cold pressing forming mould need to be arranged.
Summary of the invention
The utility model provides a kind of cone melon lobe mould of colding pressing for problems of the prior art and deficiency.
Technical scheme: a kind of cone melon lobe mould of colding pressing, comprise conical section and straight portion, wherein the cone angle scope of conical section is 55～65 °, and straight portion is from inside to outside restrained the formation reducing, and its reducing limit and the axis slanted angle number of degrees are 5～7 °; Conical section and straight portion arc transition, arc radius scope are 169～173mm.
Preferably: the cone angle of conical section (bilateral symmetry bus angle) is 60 °, and straight portion is from inside to outside restrained the formation reducing, and its reducing limit and the axis slanted angle number of degrees are 6 °; Conical section and straight portion arc transition, arc radius are 171mm.
Be distributed with breach on the port of straight portion, this breach bottom surface is parallel with the base; Jagged respectively on the port of conical section, this breach bottom surface is vertical with the base.
Circular diameter is 2980.88mm in the port of straight portion, and circular diameter is 2297.89mm in the port of conical section.
Beneficial effect: 1, change traditional cone melon lobe hot pressing for colding pressing, saved the energy, reduced the production friendship phase.
2, the unitary mould that changes in the past designs and hot pressing melon lobe Design of Dies pattern, and melon lobe cold stamping die adopts different positions to choose different springback capacities.
3, according to the deformation characteristics of the cone of colding pressing, adopt R to get the Mold Making mode of digging dark and straight flange introversion combination.It is rational in infrastructure, and result of use is good, and the one-shot forming rate is high, reduces the workload of secondary operations, is beneficial to very much promotion and implementation.
Description of drawings
Figure l is the cold pressing cross-sectional view of cone melon lobe mould of the utility model.
Among the figure, label 1 is conical section, and 2 is straight portion, and 3 is the arc transition part, and 4 is the breach of straight portion, and 5 is the breach of conical section.
The specific embodiment
Embodiment one: referring to Fig. 1, a kind of cone melon lobe mould of colding pressing comprises cone portion, 1 and straight portion 2, wherein the cone angle of conical section 1 (bilateral symmetry bus angle) is 60 °, and straight portion 2 is from inside to outside restrained and formed reducing, and its reducing limit and the axis slanted angle number of degrees are 6 °; Conical section 1 and straight portion 2 arc transition, the radius of arc transition part 3 is 171mm.
Be distributed with breach 4 on the port of straight portion 2, this breach bottom surface is parallel with the base; Respectively jagged 5 on the port of conical section, this breach bottom surface is vertical with the base.Circular diameter is 2980.88mm in the port of straight portion 2, and circular diameter is 2297.89mm in the port of conical section 1.
