Description

Technical Field

[0001] The utility model relates to the technical field of aviation component processing, in particular to a bending die for aviation component processing. Background Art

[0002] Aviation parts refer to various parts used to manufacture and repair aircraft, including engines, wings, landing gear and other key components. When processing aviation parts, bending dies are needed to bend the aviation parts into a certain shape to meet actual use requirements.

[0003] According to a bending die for machining aviation parts with convenient engagement published by a Chinese patent, the publication number is CN212551357U, comprising a fixed support plate fixedly mounted on the top of a fixed plate, a hydraulic rod symmetrically mounted on the bottom of the fixed support plate, an upper die fixedly connected to the bottom of the hydraulic rod, a lower die fixedly mounted on one side of the fixed plate corresponding to the position below the upper die, and buffer grooves are provided at the four corners of the top of the lower die. The utility model facilitates the staff to move the upper die through the hydraulic rod, and facilitates the upper die and the lower die to be guided into the limiting groove through the lower guide block and the upper guide block during the merging process, thereby avoiding the position offset of the upper die and the lower die during the merging process, causing the upper die and the lower die to be unable to be molded together. At the same time, through the buffer spring, the lower guide block can be buffered during the merging process of the lower guide block and the upper guide block, thereby avoiding the lower guide block from being squeezed and damaged instantly;
