Aluminum alloy plate bending limit evaluation device capable of automatically adjusting gap

Abstract

The invention discloses an aluminum alloy plate bending limit evaluation device capable of automatically adjusting a gap and belongs to the field of testing. A screw driving assembly, a left-right-handed screw, a supporting assembly and a set of bending die are arranged on a bottom plate; a left-handed external thread section and a right-handed external thread section of the left-right-handed screw are respectively and correspondingly provided with a female die holder; the two female die holders are respectively provided with a female die supporting roller; a male die holder is arranged above the midpoint of the left-right-handed screw, and a male die is fixed below the male die holder; a first grating ruler, a load sensor and a second grating ruler are arranged; the output ends of the first grating ruler, the second grating ruler and the load sensor are correspondingly connected with the signal input end of a PLC respectively; and the signal output end of the PLC is correspondingly connected with the control end of a servo driving motor, and the signal output end of the PLC is further correspondingly connected with a touch screen, so that a man-machine interaction and control interface of the evaluation device is formed. The bending process can be dynamically monitored, and the problem that the bending process cannot be recorded in real time when a gap value is manually measured by an experimental device is solved.

Description

technical field [0001] The invention belongs to the field of testing devices, in particular to a bending limit evaluation device for aluminum alloy plates. Background technique [0002] With the rapid development of the aerospace and automotive industries, as well as the increasing demand for energy conservation and environmental protection, higher requirements are placed on material performance. [0003] Aluminum alloy sheets are attracting widespread attention and applications due to their light weight, high specific strength and specific stiffness, good formability, corrosion resistance, and recycling potential. [0004] At the same time, as the shape of aerospace and automotive parts becomes more and more complex, the quality requirements become more and more stringent, and the forming process becomes more and more refined, bending performance, as an important part of the forming performance of sheet metal, is causing engineers More and more attention has been paid to i...
