Equipment Description:

The BTP-300 metal sheet forming testing machine is mainly used for testing the ductility of sheet metal, as a process test for metal thin plates. It is mainly used for measuring the cupping value of metal thin plates, and can also measure the forming limit curve of metal thin plates and thin strips. Can be used for the experiments of Nakajima and Marciniak. The host adopts hydraulic clamping and servo stamping, and the stamping speed can be pre-set. The cupping fixture is convenient for loading and unloading samples. After the sample is sent in, pressing the automatic button can complete clamping and stamping. The sample automatically stops when cracks appear and is easy to observe. It has peak memory function, which automatically remembers the maximum impact force and deformation height. The deformation depth and impact force are displayed on an LCD screen, and can be pre-set through button operation.

The machine uses a servo motor to drive the reducer, which then drives the synchronous toothed belt and ball screw for loading. The loading is smooth, the speed is accurate, and the loading load is measured in real-time, making it easy to determine the moment when cracks appear. When clamping, the synchronous transmission component drives the servo stamping system to synchronize upwards, and then the clamping system sends a signal. The stamping system automatically stamps, and the displacement measurement system synchronously measures the deformation value of the sheet metal. When cracks appear in the sample, the measurement system automatically displays the cupping value. The cup protrusion fixture is an open structure, which facilitates observation of whether there are cracks in the board. The cup protrusion fixture pressure mold structure adopts a ball and socket automatic centering structure to ensure uniform clamping force of the sample during clamping.

The testing machine is equipped with a BVE three position full field strain measurement system, which can be used for measuring the forming limit curve FLC.

The product complies with GB/T4156-2007 and GB24171.2 standards.
