The sheet metal configuration component which is formed the sheet metal configuration component which has the square corner which possesses three edges which are suited for laser welding, it produces and optimizes the mannered null sheet metal

摘要

The present invention, sheet metal components which are formed by bending a (10) comprises a (11) corners with edges of three edges of the two corner (11) (12, 13) is a metal formed by the (2, 3) sheet metal foot pieces of first or second bent at _(, 1, _{R i, 2 R i)} thin plate blank (1), the bending radius of the inside areas, the edges of the three The third edge (11) (14), are formed blank two edges (2, 3) both sheet metal leg piece bent by (4,5) with corner sheet metal blank (1 and a inner angle (6), recesses wedge opening (6) interior angles and (7), the wedge tip, which is rounded (7a, and 7b) 2 wedge edge recess (7)) is, (7c sheet metal components which are formed by a) on (10). Place the interval for u (A) of the bending line (2) leg bending the first intersection (7a, 7b) (8), the bending line of (3) leg bending of the second wedge both sides I'm at a distance x against (B). Wedge the first side (7a), the point of intersection with another (8), spaced with respect to v (A) bending line, are spaced apart with respect to z (B) and the bending line (9a) it is defined by. Wedge sides of the second (7b), intersection (8), an interval T for (A) the bending line, you are at a distance y for (B) further point bending line of another (9b) It is defined by the. T = (0.7 × S + VK / 2) ± 20% (where, S is the thickness of the metal sheet. The fractional shortening VK) interval T, u, v, x, y, z are,, u = ( 1.0 × _{R i, 1)} ± _20%, v = (1.0 × _{R i, 1)} ± _20%, x = (1.0 × _{R i, 2)} ± _20%, y = (0. It is defined as a 20% z = (VK / 2-0.1) ± and 20% 25 × _{R i, 2)} ±.
