C-speed stamping presses associated operational requirements?
The thickness of the high-speed stamping material shall meet the standards prescribed by the State, because a certain punching die gap suitable for a certain thickness of material, material thickness tolerance is too large, not only directly affect the quality of parts and may also cause damage to the mold and punch.
Open high-speed stamping presses related operational requirements?
Open high-speed presses in operation, there are other requirements?
High-speed stamping performance requirements
For high-speed molding step, in order to facilitate the deformation and improve the quality of stamping parts, high-speed stamping material should have good ductility, yield ratio is small, the thickness of the directivity coefficient, plate plane directivity coefficient is small, the yield strength of the material and the ratio of the elastic modulus is small. For the separation step, without stamping material with good ductility, the better because the plastic material, the more easily separated, but should have a certain plasticity.
High-speed stamping surface quality requirements
High-speed stamping surface should be smooth, non-hierarchical and damage mechanical properties, no rust, scale and other attachments. Because the better the surface quality of the material, the more difficult to break down when punching, easy bruising quality of the mold, the workpiece surface is also possible.
The specific requirements of the rail material
Rail length according to the structure of punch and precision requirements, the general cast iron HT15-32, HT20-40, if high speed slider, eccentric load, guide rails may face sandwich of bakelite cloth or copper to reduce wear, material grades of copper bronze ZQSn6-6-3, ZAQAl9-4 and brass ZHMn58-2.
