Metal stamping die production process

One. Raw material processing:

1. Milling six face squares (perpendicularity error is not greater than 0.1/300), the same mold material length and width dimensions can be the same, the thickness of 0.2mm wear (the quenched parts need to leave 0.5mm wear); edge chamfer . 2. Grind the upper and lower planes, (the workpiece needs to be quenched to leave 0.3mm)

two. Machining

1. Drill and tap the screw holes, through holes and thread holes according to the drawings;

2. Milling the leaking holes or forming parts;

3. After heat treatment, the workpiece needs to grind the upper and lower planes and the reference edge;

4. Turn the turning parts, the tolerances are in accordance with the requirements of the drawing.

☆☆All pin holes can not be processed first: drill threaded holes that need heat treatment, and the rest are assembled with drilling and reaming three. Wire cutting:

Cut each forming part according to the matching requirements specified in the drawing.

The guide post, the guide sleeve and the mold base are tightly matched; the punch and the fixed plate are in transitional fit; the pins and the holes are in transitional fit.

four. assembly:

1. Assemble the mold base according to the figure first to ensure that the guide post and the guide sleeve are perpendicular to the mold base and move smoothly;

2. Fix the concave mold on the mold base first, and evenly place the copper skin of the corresponding thickness on the periphery of the concave mold according to the given gap in the drawing, and then install the convex mold, test the paper sheet to confirm that the surrounding burrs are even, then tighten the convex, The die is equipped with pins. (If it is a compound die, you need to align the punch gap and then fix the convex and concave die).

3. Afterwards, install the unloading and ejection mechanism. Overall mold processing sequence:

Priority is given to processing workpieces that require heat treatment. 2. Second processing. Workpieces that require wire cutting. 3. Then process the mold base parts, namely the upper support and base. 4. Then process other parts. 5. Assemble and try out
