Description

technical field [0001] The invention relates to the technical field of stamping test equipment, in particular to an integrated test platform and method for test piece stamping forming and mechanical parameter testing. Background technique [0002] At present, there are two main methods for preparing and forming specimens of similar materials: manual compaction and hydraulic press pressing. [0003] The specific implementation process of the manual preparation method is as follows: firstly, the similar materials with a good proportion are put into the mold; then, it is manually tamped with a hammer; finally, the mold is demolded, and the test pieces of the similar materials are taken out. The specific implementation process of hydraulic press pressing is as follows: first, put similar materials with good proportions into the mold; then put the mold indenter on the mold; then rely on the hydraulic press to set the pressure, compact and form; finally demould and take out speci...

Problems solved by technology

[0004] However, the above-mentioned traditional preparation methods all have certain defects. For example, a hydraulic press can control the pressure of similar materials to solve the problem of the compactness of the test piece.

However, the molding speed is too slow to meet the production requirements of a large number of similar material test pieces in a short period of time, and the test piece production cycle is long

[0005] The non-uniform compaction of the test piece and the excessive time interval between the forming and demoulding of each test piece will affect the test results of various mechanical parameters of the test piece, reduce the stability of the mechanical properties of similar material test pieces, and bring greater impact to the results of the model test. error

[0006] The pressing of similar materials and the testing of mechanical parameters are often two closely linked links. At present, there is no equipment that can simultaneously satisfy the high-efficiency and precise pressing of similar material specimens and complete the mechanical parameter testing experiments of similar material specimens.
