Embodiment Construction

[0053] Such as Figure 1 to Figure 4 The device 10 for punching shown in is intended to punch blanks 50 for the purpose of producing punched parts, in particular deep-drawn parts.

[0054] In an embodiment, the blank 50 is made of a metallic material, such as steel.

[0055]The blank 50 has a first surface 51 and a second surface 52 opposite the first surface.

[0056] In preferred non-limiting embodiments of the present invention, such as Fig. 1 to Figure 4 The apparatus 10 for stamping shown in cross-section in is suitable for manufacturing cups. The term "cup" refers to a stamped part having a hollow cylindrical shape.

[0057] Those skilled in the art will readily appreciate that the teachings of the present invention can be transposed into other embodiments.

[0058] In this specification, refer to Figures 1 through Figure 4 The orientation of the various elements shown in , using terms such as "upper", "lower", "top", "bottom", "left", "right" for the sake of simplic...

Abstract

The invention relates to a device (10) for stamping a blank (50) in order to produce a stamped part. The device includes a punch (21) including a bearing surface (211), an anvil (22), and means for generating a magnetic field (34). The stamping device being configured, in an initial position, so that: the bearing surface (211) of the punch (21) is intended for receiving a portion of a first surface (51) of the blank (50); the anvil and the means for generating a magnetic field are intended for being arranged on either side of another portion of the blank, with the anvil (22) facing the first surface (51), and the means for generating a magnetic field facing a second surface (52) opposite the first surface. The means for generating a magnetic field (34) are capable of applying a pressure onthe blank (50) towards the anvil, in a direction ZZ'. The stamping device also includes movement means (23) arranged to move the punch (21), relative to the means for generating a magnetic field (34), in a direction opposite the direction ZZ'.

Description

technical field [0001] The present invention relates to the field of forming, and more particularly to stamping. [0002] The invention relates to a device and a method for stamping blanks by magnetic pulses to produce stamped parts, in particular so-called deep-drawn parts. Background technique [0003] In the field of forming, especially metal forming, stamping is often the method of choice because it is robust and well controlled. [0004] Due to the high production speeds possible, stamping is commonly used in industry, especially in the automotive industry, for forming in particular lining panels, such as bonnets or doors of motor vehicles. [0005] Stamping is a process for forming which consists in obtaining parts with more or less complex shapes via plastic deformation of a blank under the action of pressure. [0006] The device for stamping used to carry out the method generally comprises a die and a punch of practically complementary shape, between which the blan...
