摘要： SUMMARY
The present invention concerns the implementation of production processes based on sheet metal molding, for the manufacture of some mechanical elements.
Among the mechanical elements that are very rarely made by sheet metal molding there are some pieces that are commonly defined as mechanical "arms".
A mechanical "arm" is an elongated mechanical element in which, typically, in correspondence with the two heads, there are holes, designed to couple this mechanical "arm" to other elements of a more complex mechanism. In particular, the mechanical "arms" used to transfer a movement, or a force, from one point of a mechanism to another, have non-negligible mechanical resistance requirements, they are relatively large, and have complex shape characteristics to be obtained through sequences of cuts and folds.
The present invention, while accepting the use of more complex molds than those normally used, aims to indicate a new production method that can be applied for the production of a number of mechanical "arms", even when their shape requires a greater thickness than that obtainable from cutting a single sheet metal and, above all, when requirements of mechanical resistance and precision of the holes are required, such that the known technique is still oriented towards production methods other than sequences of cuts, folding, drawing, i.e. processes of sheet metal molding.
These objectives can be achieved through a production method which involves manufacturing a mechanical "arm" starting from an initial flat piece of sheet metal, suitably shaped, so as to present a symmetry with respect to its longitudinal axis. The method then uses a special mold composed of a decomposable matrix and a pair of punches.
This special mold allows you to make the edges of the holes on the heads of the "arm" being processed, when the semi-finished product is already folded: this allows you to control the dimensions of these holes with excellent precision.
Furthermore, the method benefits from the dismantling of the matrix of the mold, to be able to free the "arm" from the matrix itself, even after the holes have been trimmed, preventing it from getting stuck inside the "arm".

摘要： A bead forming method includes the steps of preparing a bumper stay 10 having a partition wall 12 that partitions an internal space and extends in a longitudinal direction, an elastic body 40 that can be inserted into the bumper stay 10, and a pusher 61 that presses the elastic body 40; inserting the elastic body 40 into the bumper stay 10 and arranging the elastic body 40 in the bumper stay 10 so as not to come into contact with the partition wall 12; and forming a buckling bead 11a by compressing the elastic body 40 in the longitudinal direction of the bumper stay 10 by the pusher 61 to expand the elastic body 40 outward in a radial direction without coming into contact with the partition wall 12, thereby bulging a part of an outer wall 11 of the bumper stay 10 outward in the radial direction without deforming the partition wall 12.
