Product Name:BTW-300 microcomputer control of sheet metal forming machine

Product Description
BTW-300 microcomputer control of sheet metal forming machine is mainly used for ductility detection plate, process test of sheet metal, sheet metal is mainly used for measuring, cupping value at the same time, determination of metal sheet and strip forming limit curve (FLC test). Nakajima and Marciniak can be used for the test. The host adopts hydraulic clamping, servo press, stamping speed can be preset. Cup fixture handling sample into the sample, convenient, complete clamping, automatic button according to stamping. Specimen crack automatic parking, and easy to observe the crack. A peak value memory function, namely the maximum pressure, deformation height automatic memory. The deformation depth. Pressure using LCD display, key operation, a predetermined deformation depth.

Product details

The machine is driven by servo motor and reducer, driven by synchronous belt and ball screw loading, loading speed is stable, accurate, real-time measurement of load, easy to determine crack moment. The clamping force from the hydraulic oil source independent load, the clamping force can be adjusted, sensor direct force measurement, data display, can independent calibration. After clamping by the synchronous transmission module, servo drive stamping system synchronous up, automatic stamping system, displacement measurement system of synchronous automatic measurement of sheet deformation value, when the crack specimen, cupping value measurement system of automatic display. Cup fixture for the open type structure, convenient to observe whether the plank crack cup. Process fixture die structure using self-aligning ball structure, to ensure that the specimen clamping force uniform specimen clamping force.

The testing machine can be used to match the BVE three full field strain measurement system, which can be used for the determination of the forming limit curve FLC.

The product conforms to GB4156-2007, GB/T24171.1, GB/T 24171.2, GB15825.3 standard.
