Technical Solution

1、 Product Overview:

Mainly used for process performance testing of metal sheets and strips, to inspect the plastic deformation performance of sheets and strips. Meet national standardsGB/T 4156-2020Metal Materials Requirements for Thin Plate and Thin Strip Cup Bulge Test. This machine is mainly used to test the plastic deformation performance of metal sheets and strips, usingPure electronic mechanical tightening buffer device，punchTop broken sample, with automatic stopping function when cracks appear on the board;Can be matchedcamera(Optional)The cupping value at the moment of crack occurrence can be more accurately determined through the video playback function.

Experimental principle:

Punch a punch with a spherical end onto a sample clamped in the cushion mold and pressure film to form a dent until a penetrating crack appears. The depth of the dent measured by the displacement of the punch is the test result. Even with a certain specification of steel ball or spherical punch, it hasApply pressure to the specimen with a clamping force of 10kN until a penetrating crack is formed. At this point, the depth of the punch pressing (mm) is the cupping value of the plate, which is used to determine the plastic deformation performance of the material.

3、 Performance and features:

1. The cupping test machine adopts automatic control of the loading of test force, which is easy and simple to operate;

2. The load sensor measures the test force with accurate and reliable readings;

3. The computer controls the test process according to the national standard test requirements, displays various test data on the screen, draws test force time curves, and automatically processes the curve data;

4. It has complete file operation and data storage functions, making it easy for users to process data;

5. Printer printing test report;

6. Equipped with complete safety protection devices:

7. When the test force exceeds 2% -5% of the maximum test force for each level, overload protection is activated and the system is unloaded;

8. When displacement occursencoderWhen reaching the front and rear limit positions, the travel protection and motor stop.

4、 Advantages

1. The cup protrusion testing machine adopts a new structural principle, which loads the servo motor at a constant speed and can achieve constant speed control. The stamping process is controlled by a PC computer, and the stamping speed can be infinitely adjusted and pre-set.

2. Clamping force is determined bymotorIndependent loading, adjustable clamping force, synchronized data display, and independent calibration.

3. The force measuring device has been changed from hydraulic sensors to spoke type sensors, and the measurement of cup protrusion value has been changed to encoder measurement. Combined with spoke type sensors (direct force measurement), the accuracy and reliability of measuring cup protrusion value on the testing machine have been greatly improved.

4. The cup protrusion fixture is easy to replace and the sample is easy to load and unload. After the sample is placed, it can be clamped by pressing the automatic button. The test parameters can be input and changed, and the stamping process is fully automated with one click without human influence. It can achieve closed-loop control. When the punching pressure value drops, the sample will automatically stop if a crack occurs. At the same time, it is easy to observe the test process and can more accurately determine the cup protrusion value at the moment of crack occurrence.

5The experimental data is displayed on the computer and has peak memory function, such as high impact pressure, cup protrusion value, etc. It realizes the reporting, storage, batch, curve drawing, etc. of the experimental results, automatically remembers the deformation height, and can automatically restore to the state to be tested after one experiment.
