Aluminium alloy sheet forming blunt needle break easily the reason and solution

Dongguan precision electronic technology co. , LTD. , is a large aluminum alloy mesh factory. High-speed stamping aluminum alloy fine mesh, aluminum alloy, aluminum alloy holes microporous, aluminum alloy sheet forming. 。 。 。 。 。 Microporous materials, sheet molding processing for aluminum alloy in general use: aluminum alloy, steel, stainless steel, hot die steel, cemented carbide, ceramics, diamond and other materials. In the stamping sheet molding whether we also encountered such a problem, blunt needle is easy to break. Caused by blunt needle easy break may be blunt needle problems of its own, may also mould design flaws; May is the cutting material. 。 。 。 。 。 General solution is: male splint unilateral tolerance & plusmn; 5 mu, stripper unilateral 0. 1毫米; Blunt needle deviation, if you want to try to blunt needle do short, clearance to put appropriate, guide pin to use bigger, the clearance between the guide bush of concave die and shall not exceed the unilateral 0. 005mm。 Stripper gap is smaller than the template, take bilateral commonly 0. Bilateral 0 005 mm, and plywood. 02 mm, loose points also has nothing to do, the punch should not forcibly type, but with handle gently push into. Precision contact: Chen Gong
