A pair of cold molds includes a cutting die, a cutting blade, a die, and a stamper, and the repair of the reuse is described below.
1 cutting die
The quality of the cutting die determines the quality of the cut and the quality of the steel ball. For the repair of the cutting die, only the working surface of the cutting die can be ground, and the grinding amount is 0.5 m. Since the length of the cutting die has been fixed, wear off 0.5
Mm, add a spacer with a thickness of 0.5mm for filling.
2 cutting blade
Like the cutting die, the quality of the cutting blade determines the quality of the cutting material and the quality of the steel ball. For the repair of the cutting blade, only the working surface of the cutting blade can be ground, and the grinding amount is G.5ma. Grinding out
Points, compensation in the adjustment.
3 die and stamper
The repair of the die and the stamper lies in the repair of the working part, ie the ball socket. Since the ball and socket portion is a damaged portion, the repair of the die and the stamper can only repair the ball socket. Measured by grinding,
The thickness of the ball socket fatigue layer is 0.30.35 mm. During the test, it is concluded that the thickness of the fatigue layer to be ground is preferably 0.5 m. For example, the 14.5m die and stamper after wear can be changed to 15
Mn die and stamper. The 5mm die and stamper after wear can be changed to 15.5m die and stamper, and so on.
