Abstract
The utility model relates to a large oval-shaped seal head. The large oval-shaped seal head is characterized in that the orthographic projection of the large oval-shaped seal head is of an elliptical sphere structure, the long axis of the inner diameter of the elliptical sphere structure is 3516mm, and the short axis of the inner diameter of the elliptical sphere structure is 3316mm; and the seal head comprises a tip circle, a first-layer arc-shaped section and a second-layer arc-shaped section, the tip circle is fixedly welded with the first-layer arc-shaped section, and the first-layer arc-shaped section is fixedly welded with the second-layer arc-shaped section. The seal head is divided into three portions to be manufactured according to the width and the length of a plate, a method for manufacturing a large-opening portion of the seal head includes manufacturing a mold and performing hot-pressing, then cutting and assembling are carried out, a middle zone and the tip circle are formed by a spinning and bulging method, then cutting is carried out, assembling is omitted, and accordingly a manufacturing process can be simplified. The large oval-shaped seal head is reasonable in structure, easy to manufacture and machine, high in strength, good in performance and quite favorable for popularization and implementation.
Description
Technical field
The utility model relates to the major diameter end socket manufacturing technology of metal production industry, is specifically related to a kind of large-scale oval end socket.
Background technology
Large-scale oval end socket is applied to Ladle Bottom, and this kind end socket belongs to the Special-shaped end socket, and its making has certain difficulty, need to make special-shaped mould and carry out punching press, early stage large-scale oval end socket belongs to imported product, all has difficulties in the model operation and maintenance, and productive costs is higher.Along with the purposes of abnormal head is more and more wider, production is also more and more, but still lacks the ripe research and development technology of this series products.
Summary of the invention
The utility model provides a kind of large-scale oval end socket for situation about existing in the prior art and problem.
Technical scheme: a kind of large-scale oval end socket, its orthogonal projection is oval ball shape structure, and the internal diameter major axis of this ellipsoidal structure is 3516mm, and the internal diameter minor axis of this ellipsoidal structure is 3316mm.
This end socket comprises tip circle, and ground floor circular arc section and second layer circular arc section are welded and fixed between tip circle and the ground floor circular arc section, are welded and fixed between ground floor circular arc section and second layer circular arc section.
The diameter of described tip circle is 100mm, and the radian of ground floor circular arc section is 6000mm, and the radian of second layer circular arc section is 300mm.
The thickness of the tip circle of this end socket, ground floor circular arc section and second layer circular arc section is 50mm, and material is the 16MnR alloy steel.
Beneficial effect: the utility model is once compressing, strict control Mold Making precision, guarantee product compacting model, large notch portion takes to make mould, then carries out the method for hot pressing, and it is right then to cut and organize, the method that Intermediate Gray and tip circle partly take spinning to beat a drum is carried out moulding, then cut, no longer be grouping, the energy simplified manufacturing technique; It is rational in infrastructure, makes easily processing, and intensity is high, and performance is good, is beneficial to very much promotion and implementation.
Description of drawings
Figure l, 2, the 3rd, the cross-sectional view of the large-scale oval end socket of the utility model.
Among the figure, label 1 is tip circle, and 2 is ground floor circular arc section, and 3 is second layer circular arc section.
The specific embodiment
Embodiment one: referring to Fig. 1, and a kind of large-scale oval end socket, its orthogonal projection is oval ball shape structure, and the internal diameter major axis of this ellipsoidal structure is 3516mm, and the internal diameter minor axis of this ellipsoidal structure is 3316mm.
This end socket comprises the top, 1, and ground floor circular arc section 2 and second layer circular arc section 3 are welded and fixed between tip circle 1 and the ground floor circular arc section 2, are welded and fixed between ground floor circular arc section 2 and second layer circular arc section 3.
The diameter of described tip circle 1 is 100mm, and the radian of ground floor circular arc section 2 is 6000mm, and the radian of second layer circular arc section 3 is 300mm.The thickness of the tip circle 1 of this end socket, ground floor circular arc section 2 and second layer circular arc section 3 is 50mm, and material is the 16MnR alloy steel.
