sheet metal stamping technology is suitable for punching, cutting and wiping cabinet structures such as silent cabinets and power distribution cabinets.

Punch: Punch of different tonnage shall be selected according to the punch force of the workpiece. Used molds may only be reused after passing inspection. Strictly carry out the first piece inspection, middle spot check and tail piece re-inspection; Check the processing size of the workpiece according to the drawings or process documents;

The punching edge shall not be elongated or bent, and the burr height shall not be greater than 10%-15% of the material thickness; precision sheet metal processing trial run to check the safety and reliability of mechanical and electrical properties; parts that need to be processed materials should be processed after passing the previous process inspection; technical requirements should be clarified before processing, and check whether the feed There is an error; know that the corresponding mold is selected according to the processing requirements; first, place the slider of the punching machine at the top dead center, and install the upper module into the groove of the slider handle, then lay it flat. Tighten the screws and the top wire, there must be no gap between the upper module and the bottom of the slider.

Wipe clean the bed surface, remove oil and iron filings, and then place the lower module on the press table; Jogging the car or handwheel, move the slider to the lower mold to the lower mold, adjust the height of the connecting rod to make the mold stroke appropriate; adjust the mold gap to ensure that the surrounding gap is consistent; press down and flatten the lower module pressure plate, the height of the horn and the bottom plate must be the same, and the fixing points must be symmetrical. Lock the connecting rod to check whether the mold is loose; test the blank, check whether the slices are neat, uniform and consistent; adjust the circuit board according to the processing size requirements of the bent sheet metal, and set vertical reference (front and rear) and horizontal reference (left and right); understand During the processing, the material should be close to the board, and the upper part of the bottom mold should be flat; pay attention to the processing direction when punching and wiping corners to avoid punching; finished products shall be neatly classified and labeled.
