Qualification inspection steps of stamping die

In order to shorten the processing cycle of the stamping die, strengthen the precision of the die, and the methods of the spinning operator, reduce the abnormalities that occur during the production of the die, and ensure the production quality and die life. The assembly process of stripper plate is explained separately, but after the completion of each component, the basic assembly of a set of molds has been completed, but further inspection is needed. After the stamping die assembly is completed, the mold needs to be inspected according to the following 6 steps: 1. After the assembly is completed, check whether the die surface is flat. 2. Whether the movable parts are flexible. 3. Check if there is any blockage in the waste hole of the die gasket. 4. Whether the mold information engraved on the front side of the upper mold base is complete. 5. Whether the adjusting rod is adjusted to the position of the terminal surface. 6. Whether the adjusting rod interferes with the main pillar, guide bushing or ball bushing. Precautions for stamping die assembly parts processing and size confirmation: 1, template warpage (0.006/100mm), whether the thickness is out of tolerance (±0.002mm). 2. The phenomenon that the hole is not processed, the place is not processed, and the processing is insufficient. 3. Adjust the width and depth of the rod groove. 4. Depth and verticality of screw hole, smooth rotation. 5. Movable guide pin hole activity, front countersunk hole depth. 6. Up and down mobility of movable parts. 7. Compatibility between the template frame and the entry block. 8. Depth of escape from the board into the block hanging platform. 9. Confirm the hole size of the template. 10. Test whether the punch can pass through the stripping into the block. (Because it can't be passed through and processing is time-consuming) 11. V-cut, fan-shaped adjustment punch is made of wc material. 12. The R angle of the floating pin is enlarged and polished. 13. The force of the pre-compressed material spring for bending forming is increased. 14. The size of the upper and lower moving blocks cannot be the same to avoid indentation. 15. Non-cutting into blocks, the parts can be placed in the frame with a gap of 0.002mm/side as appropriate. 16. Assemble the built-in block (especially the off-board into the block) and knock it flat with unheated flat iron blocks. After the division of labor in the early stage of the stamping die, and then through the inspection after closing the die, a set of die has been completed, and you can start to choose a matching punch test die.
