Precision stamping is a precision blanking method developed on the basis of ordinary stamping technology.
The result of this processing method is that the punched surface of the stamping part has no cracks and tears throughout its entire material thickness. In addition, it can also achieve the most stringent dimensional accuracy and straightness tolerance.
Of course, compared with ordinary stamping, the mold structure of precision stamping has an additional gear ring pressure plate and ejector, and the gap between the male and female dies is extremely small, and the die edge has rounded corners. During the stamping process, before the punch contacts the material, the gear ring pressure plate presses the material against the die through force, thereby generating lateral side pressure on the inner surface of the V-shaped teeth to prevent the material from tearing in the shear zone and the lateral flow of the metal. While the precision stamping punch presses the material, the material is pressed by the counter pressure of the ejector. In addition, the stress concentration is eliminated by using the extremely small gap and the die edge with rounded corners, so that the metal in the shear zone is in a three-dimensional compressive stress state, eliminating the tensile stress in the zone, improving the plasticity of the material, and fundamentally preventing the bending, stretching, and tearing phenomena that occur in ordinary stamping. The material is stamped into parts in the form of pure shear along the edge shape of the die, thereby obtaining a high-quality smooth and flat shear surface. In precision stamping, the clamping force, stamping gap, and die edge radius complement each other and are indispensable. Their influences are interrelated. When the gap is uniform and the fillet radius is appropriate, a smooth section can be obtained with a small press. Well, we have already understood the specific advantages of precision metal stamping. Let’s see which industries it is used in. The types of precision metal stamping parts include the following:
1. Auto parts: including automotive structural parts, automotive functional parts, automotive lathe parts, automotive relays.
2. Electronic parts: such as connectors, connectors, brush parts, electrical terminals, elastic parts.
3. Home appliance accessories: including home appliance parts and small home appliance parts (various structural parts and functional parts).
4. IC integrated circuit lead frame: including discrete device lead frame and integrated circuit lead frame.
5. Motor core: including single-phase series motor core, single-phase household motor core, single-phase shaded pole motor core, permanent magnet DC motor core, industrial motor core, plastic-sealed stator core.
6. Electrical core: including E-shaped transformer core, EI-shaped transformer core, I-shaped transformer core.
7. Heat exchanger fins: including industrial heat exchanger fins, household heat exchanger fins, automotive heat exchanger fins.
8. Other parts: such as instrument parts, IT parts, acoustic and camera parts, modern office parts, daily hardware.
The characteristics of precision metal stamping parts include rich variety, diverse materials, large automated production batches, high precision, complex shapes, high technical content and high added value. These characteristics make precision stamping parts widely used in the fields of metal processing and machinery manufacturing.
