GB/T 4156-1984 Metal cupping test method (thickness 0.2-2mm)

This standard is applicable to the cupping test of metal plates and strips with a thickness of 0.2~2mm and a width of equal to or greater than 90mm. It is used to test the plastic deformation performance of metal plates and strips.

UDC660:620.162.2
GE415684
This is suitable for the cup test of the metal plate with a size of 100m. The plastic deformation of the metal strip is marked. The test system uses the head of the device to obtain the shape of the head. The test sample needs to be pressed into the die. The test boundary should be tested with a uniform penetration and a deep deformation. The symbol and name of the test machine are as shown in the figure and table below. The test machine should be used on a test machine with a mold, ground effect and punch. The size and tolerance are shown in the blood. The Beijing Standardization Bureau 84·024 issued

The test process
The test shall be carried out at a temperature of 10~35. If there are higher requirements for the test temperature, the test temperature shall be 235. Or the M plate of the sample bank shall be rotated 0.1mm.
5.8 In the test part: The test side shall bear the light effect in the stealing state along the fat, the lubrication of the general fat is recorded in the north, and the light effect is required. If other types of lubrication are used, the height of the two pressure wolves shall not be less than 9mm, and the height of the center plate shall not be less than 45mm,
