The surface of the sheet metal processing should be treated like this to be better!

The sheet metal processing stamping process is suitable for punching, blanking and wiping of cabinet structures such as mute cabinets and power distribution cabinets. Punch: The punching machine of different tonnage should be selected according to the punching force of the workpiece. The used mold must be inspected before it can be used.

Strictly perform the first piece inspection, center spot check, and tail piece review; the workpiece processing scale is viewed according to the drawings or process documents; the punching margin should not be stretched or tortuous, and the burr height is not more than 10% - 15% of the material thickness;

Jianshu (Shanghai) Haojin Products Co., Ltd.

Test the safety and reliability of mechanical and electrical functions; parts to be processed should be processed after passing the inspection of the previous process; clear technical requirements before processing, check whether there is any error in the incoming materials; understand the selection of the corresponding mold according to the processing requirements; Point the punch slider to the top dead center, insert the upper module into the slot of the slider mold, and place it flat; tighten the screw and top wire, and there must be no gap between the upper module and the bottom of the slider;

Wipe the surface of the bed cleanly, after cleaning the oily iron filings, place the lower module on the punching table; jog the driving or the handwheel big wheel, and push the slider to the lower dead point into the lower die to adjust the height of the connecting rod. The stroke of the mold is suitable; the gap of the die is adjusted to ensure that the surrounding gaps are common; the lower module pressing plate is pressed and flattened, the height of the horn and the bottom mold plate are equal, and the fixing points are symmetrical; the connecting rod is locked to check whether the mold is loose or not; Carry out trial filling, check whether the section is neat, uniform and common; adjust the board according to the scale requirements, set the vertical reference (front and rear) and horizontal reference (left and right); understand that the material should be tight with the board during processing, in the bottom mold It should be laid flat; when punching and smearing, pay attention to the machining direction and avoid the mistake; the finished parts should be classified and placed neatly and marked.
