Metal electrification shearing test device and test method

Abstract

The invention discloses a metal electrification shearing test device and a metal electrification shearing test method. The metal electrification shearing test device can achieve the detection of material shearing strength under the condition of high energy electrical impulse current. A base of the metal electrification shearing test device is mounted on a tester workbench, a concave mold is fixed in the middle of a groove in the base, and a convex mold is located above the concave mold; an insulation plate is located between the convex mold and a connection rod; the connection rod is mounted above the insulation plate and is fastened on the convex mold together with the insulation plate via fastening bolts; a shearing sample is placed into two round holes of the concave mold and symmetrically mounted; a high energy pulse power supply is located at the end part of the base and keeps a safety distance from the base; the lead-out wire of the high energy pulse power supply is fixedly connected onto clamping heads at the two end parts of the shearing sample. According to the invention, via researching the material mechanical performance under the condition of electrification, the influence effect of a high energy pulse on the material mechanical performance parameters is determined, the material mechanical performance parameters are provided under the condition of electrification, in particular to the shearing strength, and the device and the method are applied to electric plastic processing.

AI Technical Summary

Benefits of technology

This new type of Shear Test Device (SCT) allows us to measure mechanical properties such as tensile force without damaging them or causing any other issues like lubrication problems. Its technical benefits include improved accuracy over traditional methods due to its unique design, ease of handling, low cost, and effective performance at extreme electrical currents.

Problems solved by technology

Technological Problem: Existing experiments conducted by engineers can only measure tensile forces without considering other factors such as shearing or compressibility that affect their performance. This makes them difficult to use when studying newly discovered materials because they require specialized tools like screws or wires.
