Abstract

The invention provides a device of performing various simulative forming performance tests to a panel under warm and vacuum state, consisting of a mechanical system, a hydraulic station, a heating furnace, a cooling system, a vacuumizing system and a detection control system. A host system adopts a three-beam four-column structure, the heating furnace not only guarantees vacuum inside the furnace during testing, but also heats a mould and a check bar; a force plug and a beading rod adopt moving seal with the bottom of the heating furnace to guarantee that the vacuity inside the furnace chamber is not reduced during actuating; the cooling system can guarantee that temperature of a furnace mantle, the force plug, the beading rod, an electrode and other positions do not rise along with the rising temperature inside the heating furnace; the detection control system is responsible for acquiring every parameter in a test and controlling the test to automatically perform at the same time. The device can complete a cupping test, a drawing test, a drifting test, a conical cup test, an earing test, a rigid die bulge test and so on under the room temperature of 1311 DEG C below zero and the working pressure with the vacuity reaching 10 <-3> Pa.

Description

Technical field: [0001] The invention relates to a general sheet material formability testing machine in a warm environment, which refers to a device for performing various simulated formability tests on sheet materials in a warm environment, and belongs to the sheet material formability testing machine. Background technique: [0002] In recent years, with the increasingly serious energy and environmental problems, the lightweight of aerospace vehicles and automobiles has become more and more important. Lightweight alloys (such as titanium alloys, aluminum-lithium alloys, magnesium alloys, etc.) and ultra-high-strength steel plates have High specific strength, specific stiffness and excellent performance have become the core of aerospace and automobile lightweight. These light alloys and ultra-high-strength steel plates are difficult to form at room temperature, and generally must be processed by warm forming or hot forming. Therefore, the research and application of sheet w...
