Description

TECHNICAL FIELD

[0001] The utility model relates to the field of forging and casting technology of elliptical head, in particular to a forging and casting equipment for elliptical head. BACKGROUND

[0002] The elliptical head is composed of a rotating elliptical spherical surface and a cylindrical straight section, and the main function of the elliptical head is to close the end of the container to isolate the internal and external media. At the end of the pipeline, the elliptical head can be welded to the pipe as a terminal, and at the same time, the elliptical head is often used on the pressure container, with one head above and one below, and a straight pipe section in the middle, which together form a pot of the pressure container. The elliptical head is widely used in many fields due to its good mechanical properties and structural characteristics, and is generally made by forging and casting equipment.

[0003] Chinese patent (authorization announcement number: CN109909419 U, authorization announcement date: 2019.06.21) proposes a forging and casting equipment for elliptical head, which first moves down the main oil cylinder to make the punch move down quickly and close to the blank, thereby improving the efficiency of forging and casting. The motor provided in the invention can drive all the pistons to move down together, so that the oil in the oil cavity can be delivered to the corresponding auxiliary oil cylinder through the connecting head two and the connecting pipe, thereby ensuring that all the auxiliary oil cylinders can be filled with oil at the same time to make the punch move down on both sides and the back two sides, thereby avoiding the phenomenon of partial load and improving the processing quality. The guide column one and the guide column two provided in the invention can improve the guiding performance of the equipment, thereby further avoiding the phenomenon of partial load and improving the processing quality.
