Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation examples,

[0041] Such as Figure 3-6 As shown, the present invention discloses an automatic detection mold for the thickness-direction deformation resistance test of the plate.

[0042] Such as image 3 As shown, the assembly structure of the deformation resistance test mold of the present invention is: the compression die 4 adopts a disk shape, is located above the test piece, and bolt holes 18 are evenly distributed around it, and the assembly is completed by fixing the bolts with the testing machine. The compression punch 1 is located below the test piece and adopts the same structure as the compression die. Set the same upper and lower compression block installation structures above the punch 1 and below the die 5 that are in contact with the test piece. Wherein at the connection between the die 4 and the upper compression block 21, th...

Abstract

The invention provides an automatic detection mold and test system for plate thickness deformation resistance test, including compression die, compression punch, compression block and measurement system, which is mainly aimed at the research of plane deformation resistance in the field of plate forming. The displacement sensor is installed on the compression die, and the load sensor is placed on the compression die. The displacement and load information acting on the test sample can be monitored and collected in real time through the two sensors. The measurement system is composed of a measuring rod, a measuring solid block, and a compression spring to realize the precise transfer of displacement and deformation, so that the displacement sensor can accurately collect data. The compression block is designed with a new force transmission calculation method to complete the weight reduction of the compression block. It is installed in the center of the right-angle positioning plate and fixed by the right-angle slideway, which improves the alignment of the compression block and facilitates the replacement of compression blocks of different areas. The compression mold with automatic detection function reduces the functional requirements of the test on the testing machine and facilitates the test operation.
