The main structure and working principle of the computer control deep drawing cups testing machine
1. The cup testing machine is the precise device used to test manufacturability of metal thin sheet and banded material, according to GB/T 4156-2007<Metal materials, thin sheet and banded, Erickson-cupping testing>, it can inspect metal’s plastic deformation of metal’s thin sheet and banded in the testing, it also accords with in GB5125-85< Method for deep drawing cups testing of non-ferrous metals> for testing the characteristics of non-ferrous metal sheets.
2. Our company produced the new cupping testing machine, has changed the past oil source afterburner loaded servo motor constant speed, at the same time, we have changed the hydraulic sensor to wheel-spoke sensor, it improve the accuracy and precision of testing cupping values greatly.
3. We select high-precision grating measuring instrument to measure cupping value, so improves the controllability of the machine.
4. From the hardware configuration,or force transmission principle, it has been greatly improved than the original machine, configurate computer controlling, it realize perfection of the machine, it can also realize the result of report, storage, batch, curve plotting and so on.
5. The machine can do cupping test and the deep drawing cup test, the punch and mold easy and convenient to change;
6. This machine has a crack of plate automatic stop function, also equipped with a camera that can accurately determine the presence of cracked cups.
7. This machine adopts servo loading control system, which can realize constant rate for stamping sample loading;
8. Cup drawing value adopt encoder measurement with high precision, the highest resolution can reach 0.001 mm;
