AI Technical Summary
⚠Technical Problem
When processing thick materials with small notches, existing stamping dies result in a small blanking surface and a large blanking collapse angle, which leads to the product accuracy failing to meet requirements.
⚗Method used
Design a high-precision punching die for thick materials with small notches, which includes a pre-punching structure, a flattening punch, and a fine punching structure. The edge of the pre-punched and flattened punch is used to ensure dimensional accuracy, and then fine punching is performed.
🎯Benefits of technology
This effectively solves the problem of inaccurate measurement of boss width, ensuring product precision and quality, and achieving high-precision punching results.

Abstract
The utility model provides a kind of thick material small gap high-precision blanking die, including upper die, lower die, pre-punching structure, fine punching structure are sequentially arranged in along the feed direction in die, the pre-punching structure is used to punch out the pre-punching of first boss on material tape, and first sunken platform is formed in the inside middle part of the pre-punching;The work station between the pre-punching structure and fine punching structure is provided with flat convex die, the edge of first boss is formed first overlap area with the flat convex die, and the flat convex die is used to flatten first overlap area to make the left and right sides of first boss parallel.The utility model solves the problem that existing stamping die is small when stamping thick material tape small gap product die pressure material surface, blanking corner is big, cannot guarantee product quality.
