The sheet metal stamping process is suitable for punching, blanking and wiping of cabinet structures such as mute cabinets and power distribution cabinets. Punch: The punch 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 inspection, intermediate inspection, and tail inspection; the workpiece processing dimensions shall be inspected according to the drawings or technical documents; the edges of the punching shall not be stretched or bent, and the height of the burr shall not exceed 10% to 15% of the thickness of the material;
Test the safety and reliability of the mechanical and electrical performance of the test; the parts to be processed shall be processed after passing the inspection of the previous process; the technical requirements shall be clarified before processing, and the incoming materials shall be checked for errors; the corresponding molds shall be selected 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 should 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 gap is consistent; the lower plate is pressed and flattened, the height of the horn and the bottom die plate are equal, and the fixed 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 consistent; adjust the board according to the size 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.
