The sheet metal stamping process is actually used for punching, blanking, and cornering of cabinet structures such as silent cabinets and power distribution cabinets. Punching machine: The punching machine with different tonnage should be selected according to the punching force of the workpiece, and the mold used must be checked and qualified before it can be used. So how to process the surface of sheet metal processing better? Let’s take a brief look:
Strictly implement first piece inspection, intermediate spot inspection, and tail piece review; the processing dimensions of the workpiece are inspected according to the drawings or process documents; the punching edge should not be stretched or bent, and the burr height should not be greater than 10%-15% of the material thickness;
Test run to check the safety and reliability of mechanical and electrical functions; the parts to be processed should be processed after passing the previous process inspection; understand the technical requirements before processing, and check whether there are errors in the incoming materials; understand that the corresponding mold should be selected according to the processing requirements; first Point the punch slide block to the upper dead center, put the upper module into the slide mold shank slot, and lay it flat; tighten the screws and top wires, and there should be no gap between the upper module and the bottom surface of the slide block;
Wipe the surface of the bed clean and remove the oil and iron filings, then place the lower module on the punching table; turn the driving wheel or the big wheel of the hand wheel to make the slide block thread into the lower die to the bottom dead point, and adjust the height of the connecting rod to make The mold stroke is appropriate; adjust the punch gap to ensure that the surrounding gap is uniform; press and flatten the lower module pressure plate, the shim and the bottom mold plate should be equal in height, and the constant points should be symmetrical; lock the connecting rod and check that the mold has no looseness ; Carry out test punching, check whether the section is clean, average and uniform; adjust the board according to the size requirements, set the vertical datum (front and back) and horizontal datum (control); understand that the material must be close to the board during processing, and the bottom Place the mold flat; pay attention to the processing target when punching and wiping corners to prevent incorrect punching; the processed parts should be sorted and placed neatly and marked.
The above is the surface processing method of sheet metal processing. Welcome to consult.
