Product Name: CBW-50  microcomputer control cup test machine

Product Description
CBW-50 the appearance of the machine design fashionable, elegant, ergonomic, process performance test of precision equipment for metal sheet and strip, can achieve GB/T4156-2007< metallic materials sheet and strip Erichsen cupping testing method > to meet JJG 583-88, JB/T7408-94 requirements, also by the ASTME643-2008 standard and test metal sheet and strip in the test process of plastic deformation performance. Increased cup mold also can achieve GB/T5125-2008< nonferrous metal punching cup test method > anisotropy of non-ferrous metal plate test.

Features

1. the cupping testing machine the new structure principle, for the servo motor with constant loading speed, constant rate control, stamping process is controlled by computer, the stamping speed can be stepless speed regulation, pre setting. (in the past cylinder oil source loading cannot be achieved constant rate control).

2. the clamping force is independent of the hydraulic oil source loading, clamping force can be adjusted, data synchronization display, can be independently calibrated.

3. Poor repeatability machine adopts the movement of punch, force measuring device has been changed in the past the hydraulic sensor for spoke type sensor, Erichsen value measurement for the encoder to measure and test process in our company's first low friction mobile device with high precision spoke sensor (direct force measurement can realize ultra-thin plate test (0.05 ~ 3mm), and greatly improve the test measurement Erichsen value of accuracy and reliability. The instrument measuring device and loading device and control program of perfect matching, it is good to solve the previous test data, but also for our country to implement the new cupping machine metrological verification rules and Erichsen test method provides a reliable basis.

4. cupping, a cup of mould is convenient to replace, simple sample handling, into the sample, you can press the Auto button to finish clamping, test parameters can input, change, stamping process closed-loop control to achieve pressure value decline to judge a specimen crack automatic parking, also is easy to observe crack specimen. Test data the computer display, and peak memory function, namely the maximum pressure, Erichsen value, test results report, storage, batch, draw the curve, deformation height automatic memory, a test end can be automatically restored to awaiting trial.
