What to pay attention to when opening stainless steel microporous molds

Precision professional stamping of stainless steel micro-holes, small holes, small holes, punching, etc., needs to be opened before punching. The quality of the mold affects the quality of the mesh and the production efficiency. Next, let's look at what should be paid attention to when opening a good mold. Pay attention to the choice of die gap, choose a suitable die gap, you can extend the life of the die, and you can also punch out high-quality stainless steel micro-holes. A die with a large gap will shear or tear the blanking fracture surface. This situation can cause interlayers and burrs on the workpiece. Too small die gap will lead to inaccurate dimensional accuracy of the workpiece, increase the punching force, and make the die easy to damage. Material characteristics are also an important factor affecting the quality of the workpiece, so depending on the thickness of the material, the gap of the mold is generally about 4% to 18% of the material thickness. If the hardness of the sheet is too high, it will also affect the mold. When the sheet is relatively hard, the shear band is very narrow, and the punch will break when pressed into the sheet for a short time. When punching soft metal plates, the punch and the die Almost all cut into the sheet material, the sheet material will appear cold work hardening due to the impact of die punching. In the process of using the mold, the gap will be gradually worn and increased, so the gap should be taken to the minimum when opening a new mold. When punching the shape, the die size should take the minimum limit size of the workpiece, and when punching, the punch size should take the maximum limit size of the hole. Dongguan stamping non-standard stainless steel micro-holes, each punching product needs to be opened, and has decades of punching experience.
