Features of precision hardware machining parts.
1. The shape is complicated, specifications and location of high precision. Professional precision parts processing plant of the general material thin thickness t>3mm ~ 12.5mm, for the medium-thick plate and thick plate fine blanking parts, punching and cutting surface straight. Smooth, the quality is comparable to cutting.
2. Clear contour. Collapse angle is small, hole edge distance and hole spacing (thickness) ≤ T, with embossing . Sink hole . Buried holes, rim tabs and other molding fine punching, especially the modulus of small involute . Cycloid. Triangles. Rectangle. It is not possible to manufacture high-precision gear precision stamping parts with trapezoidal shapes.
3. They are mass production and reach the appropriate economic production scale of automotive hardware parts custom, including automotive handbrake, car, motorcycle and other commodity precision parts, these parts are broken by the raw material, no longer cut.
4. Because of the cold hardening utility, the surface strength of the fine blanking cut surface. Strength greatly improved, friction resistance and aging resistance to enhance, used as a moving surface. The gear profile of the friction surface. Precision metal stamping parts, such as bushings, will improve the service life.
