The reasons of errors occurring in the aperture in the precision stamping processing

Precision electronic technology co. , LTD is a professional precision stamping processing enterprise. Focus on production and processing precision shrapnel, metal terminals, hardware components such as tensile parts, lead frame. Products are widely used in the connector, micro motor, acoustic components, sensors, automotive electronics, new energy, medical electronics, intelligent household, diodes and IC packaging and other industries. In precision stamping processing daily, will encounter punching size small or large and differ with the punch size bigger problems. Cutting blade wear, material by tensile stress increases, stamping parts produced material, distortion tends to increase. Produce double way, punching size will be small. Stamping parts processing on the material of the crush, make the material produces plastic deformation, can lead to punching size is big. And reduce pressure, punching size will be small. Punch edge end shape. Such as end slope or arc, due to slow down the blanking force, salt pieces is not easy to turn makings, distortions. Difficult to manufacture precision metal stamping can make other methods with reinforcing rib, rib flanging, ups and downs, or artifacts, in order to improve its stiffness. Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc. Stamping parts in daily production, will encounter punching size small or large, Possible beyond specification) And the punch size is large, in addition to consider the design of the forming of convex and concave die size, machining accuracy and blanking clearance and other factors, from the above aspects should also be considered. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
