Screen display automatic cupping test machineThe composite oil cylinder adopts hydraulic clamping and hydraulic stamping, which automatically stops when cracks appear on the sample, making it easy to observe the cracks. It has a peak memory function, which automatically remembers the punching pressure and deformation depth. The flip fixture, punch and sample replacement, and loading and unloading are convenient. According to the pre-set program and data, it automatically completes clamping, stamping, measurement, calculation, and stopping.
The testing machine is mainly used for the ductility testing of sheet metal, which is a process test for metal thin plates. The main machine adopts hydraulic clamping and servo stamping, and the stamping speed can be pre-set. The cup shaped fixture is convenient for loading and unloading the sample. After the sample is sent in, pressing the automatic button can complete the clamping and stamping. The sample automatically stops when cracks appear, and it is easy to observe the cracks. It has peak memory function and automatic memory of deformation height. The deformation depth and impact force are displayed on the LCD screen, and can be pre-set by button operation.
The testing machine uses a servo motor to drive the reducer, and during clamping, the synchronous transmission component drives the servo stamping system to synchronize upwards. Then, the clamping system sends a signal, and the stamping system automatically stamps. The measuring system synchronously measures the deformation value of the sheet metal. When cracks appear in the sample, the measuring system automatically displays the cup protrusion 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. A camera device can be added to more accurately determine the moment of crack generation.
Maintenance and upkeep of the screen display automatic cup protrusion testing machine
1. Regularly checkScreen display automatic cupping test machineWhen the oil level in the tank is lower than the oil level, clean 46 # hydraulic oil should be added.
2. Change the working fluid according to the frequency of use (usually 2000 hours) to avoid oil contamination and damage to the components. Use about 30L of oil each time.
3. Do not disassemble the oil pipe casually to prevent air from entering, causing the punch and clamping die to bounce, affecting the accuracy of the cup protrusion position and the stability of the clamping force; If air enters, the cup protrusion testing machine can be started manually. The punch and cushion mold can be quickly raised and lowered several times, and then the punch and cushion mold can be slowly pressed under high pressure to discharge the air.
4. After the experiment is completed, the power supply of the testing machine should be cut off.
5. After the experiment is completed, the head of the testing machine should be coated with oil for protection, and the mold should also be coated with oil for protection.
