How To Maintain The Punching Mold Of CNC Busbar Processing Machine

Deshang CNC Equipment Co., Ltd. is a professional manufacturer of bus processing machines, Press brake, cutting machines, and Bus duct special equipment，Below, the editor will introduce to you how to maintain the punching mold of a CNC busbar processing machine.

1.Ensure the optimal mold gap, which refers to the sum of the gaps on both sides when the punch enters the lower mold. Different plate thicknesses and materials should use lower molds with different gaps. Choosing an appropriate mold gap can ensure good punching quality, reduce burrs and collapses, maintain the flatness of the sheet metal, effectively prevent material carryover, and extend the life of the mold.

2.Due to the pressure and heat during stamping, small particles of the sheet metal will adhere to the surface of the punch, resulting in poor punching quality. The adhesive can be removed by polishing with a fine oilstone, and the polishing direction should be the same as the movement direction of the punch.

3.If many holes are punched on a board, they should be punched every other hole first, and then the remaining holes should be returned for punching. This effectively alleviates the stress accumulation during sequential punching in the same direction, and also causes the stresses in the front and back groups of holes to cancel each other, thereby reducing the deformation of the board.

4.Try to avoid cutting narrow strips as much as possible. When the mold is used to cut plates with a width less than the thickness of the plate, the punch will bend and deform due to lateral forces, and the gap on the other side will be too small or wear will be intensified. In severe cases, it will scratch the lower mold, causing both the upper and lower molds to be damaged.
