Abstract

The invention discloses a thin plate high temperature forming limit testing device. The device comprises a press plate assembly, a concave mould assembly, a convex mould assembly, a guiding and supporting assembly, a heating assembly, and a sealing assembly. The press plate assembly is arranged on the upper side and lower side. The sealing assembly is arranged on the press plate assembly and the guiding and supporting assembly. The concave mould assembly is arranged in the sealing assembly. The convex mould assembly is arranged on the press plate assembly. The heating assembly is arranged in the concave mould assembly and the convex mould assembly. The provided thin plate high temperature forming limit testing device can be used to measure the forming limit pattern of a thin plate at different temperatures under different strain rates; a heating rod is arranged in the mould, thus the testing device has a compact structure; a thermocouple-relay control loop is adopted to realize precise varied temperature experiments; at the same time, an sealed environment filled with nitrogen is adopted to achieve the high temperature forming tests of metals that can be easily oxidized; and the external surface of moulds will not be destroyed due to built-in heating devices.

Description

technical field [0001] The invention belongs to the technical field of metal plastic forming technology and equipment, and provides a thin plate high-temperature forming limit test device for measuring the forming limit diagram of a thin plate at high temperature. technical background [0002] In the field of stamping forming, the forming limit diagram of sheet metal is an important graph to evaluate the deep drawing forming performance of sheet metal. It can intuitively and clearly show the deformation of sheet metal during stamping process. At the same time, the forming limit diagram of sheet metal also plays an important role in promoting the coordinated development of sheet metal properties, forming theory, forming technology and quality control. [0003] At present, the forming limit test device of thin plate at room temperature has been maturely developed. However, in a high temperature environment, due to the complexity of the heating device and the measurement devia...
