Compression-bending-clamping-integrated die for creep-aging shape-correcting process and method of use

Abstract

The invention provides a bending and clamping integrated die for a creeping, ageing and correcting process. The bending and clamping integrated die for the creeping, ageing and correcting process comprises a punch mechanism, a first wedge-shaped transmitting mechanism, a second wedge-shaped transmitting mechanism, a die base and a lower platen, wherein a lower platen mounting groove is formed in the die base; the die base is divided into a first mounting region and a second mounting region by the lower platen mounting groove; the lower platen is arranged in the lower platen mounting groove; the first wedge-shaped transmitting mechanism is arranged on the first mounting region; the second wedge-shaped transmitting mechanism is arranged on the second mounting region; a side surface of the first wedge-shaped transmitting mechanism, a side surface of the second wedge-shaped transmitting mechanism and the upper side surface of the lower platen form forming space; and the punch mechanism is arranged on the upper side of the lower platen, and is used for extruding samples to be machined into the forming space. Through the wedge-shaped transmitting mechanisms, a longitudinal force of the stroke of a punch is converted into an extrusion force in the horizontal direction, and a bending process and a clamping process are mechanically integrated.

Description

technical field [0001] The invention relates to an experimental mold for advanced forming technology, in particular to an integrated bending, clamping and clamping mold used in a creep aging shape correction process and a use method thereof. Background technique [0002] Aerospace technology competition is a contest of scientific and technological strength between countries. Since the reform and opening up, my country has vigorously developed the aerospace industry, and has successively made innovations from satellites to manned spaceflight. Aerospace technology covers a wide range and requires a high level of technology. In order to reduce the fuel consumption of the rocket during launch and increase the launch distance of the rocket, high-strength lightweight alloys have always been the preferred materials for rocket manufacturing. However, high-strength lightweight alloys such as aluminum alloys and titanium alloys are difficult to process and difficult to form. Compared...

AI Technical Summary

Problems solved by technology

[0005] For the tooling used for special parts such as satellite strips, the traditional method is cold bending first, and then manual clamping, especially the manual clamping process, due to the high strength and high resilience of titanium alloys, manual clamping The process becomes difficult, it is easy to introduce artificial asymmetry factors, and finally cause uneven stress distribution
