Tail jacking system and spinning machine tool with tail jacking system

Abstract

The invention discloses a tail jacking system and a spinning machine tool with the tail jacking system, the tail jacking system is installed on a cross beam of the spinning machine tool, the tail jacking system comprises a fixing plate used for jacking a workpiece on a mold, the tail jacking system further comprises a driving assembly, and the driving assembly drives the fixing plate to move in the axial direction of a rotating shaft of the mold so as to press the workpiece or loosen the workpiece. The fixing plate is movably connected with the driving end of the driving assembly in a rotating mode around a rotating shaft of the die. The tail jacking system has the advantages that the characteristics of end socket spinning equipment and the characteristics of end socket die edge closing spinning are fully considered, the structural arrangement is reasonable, a workpiece is effectively pressed, rotation of the workpiece along with a die is not interfered, and the spinning machine tool with the tail jacking system also has the advantages.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, in particular to a tail jacking system and a spinning machine tool with the tail jacking system. Background technique [0002] With the continuous development of China's aerospace industry, rockets have more and more demand for large-scale head parts. As a key component of super-large launch vehicle fuel tanks, large-scale thin-walled heads play an important role in the capacity and strength of fuel tanks. key role. The mechanical properties of the traditional melon petal welded workpiece are always in an unstable state at the weld, and the traditional spinning method is prone to defects such as local thinning and even processing cracks. Although the existing processing scheme also has the overall moldless spinning process and the corresponding spinning machine equipment, but in the actual reverse spinning process with molded side edge spinning, due to the large diameter of the semi-f...

Problems solved by technology

The mechanical properties of the formed workpiece welded by traditional melon petals are always in an unstable state at the weld, and the traditional spinning method is prone to defects such as local thinning and even processing cracks.

Although the existing processing scheme also has the overall moldless spinning process and the corresponding spinning machine equipment, but in the actual reverse spinning process with molded side edge spinning, due to the large diameter of the semi-finished blank, it is very inconvenient to turn it back Fixing on the finishing mold
