Abstract

A process allows the fabrication of a reinforced part from a part containing at least one area requiring reinforcement. This process includes a step (10-30) in which at least one stiffening rib of a chosen shape is defined on a metal block by 3D printing, in order to produce a ribbed block, and then this ribbed block is permanently fixed in the area to produce the reinforced part.

Claims

Claims

1. Method for manufacturing a reinforced part (PR) from a part (PC) comprising at least one zone (ZR) to be reinforced, characterized in that it comprises a step (10-30) in which at least one stiffening rib (ND) of chosen shape is defined on a metal block (PM) by 3D printing, in order to produce a ribbed block (PN), then said ribbed block (PN) produced is fixedly secured in said zone (ZR), in order to produce said reinforced part (PR).

2. Method according to claim 1, characterized in that in said step (10-30) a 3D printing technique of the so-called arc-wire additive manufacturing type is used.

3. Method according to claim 1, characterized in that in said step (10-30) a 3D printing technique of the so-called powder arc additive manufacturing type is used.

4. Method according to one of claims 1 to 3, characterized in that in said step (10-30) said ribbed block (PN) is fixedly secured by welding.

5. Method according to claim 4, characterized in that in said step (10-30) said ribbed block (PN) is fixedly secured by means of welding points (PS).

6. Method according to claim 4, characterized in that in said step (10-30) said ribbed block (PN) is fixedly secured by means of weld beads.

7. Method according to one of claims 1 to 6, characterized in that in said step (10-30) said block (PM) is stamped before carrying out said 3D printing.

8. Vehicle, characterized in that it comprises at least one piece of equipment comprising at least one reinforced part (PR) obtained by implementing a method according to one of claims 1 to 7.

9. Vehicle according to claim 8, characterized in that said equipment is chosen from a bodywork, a part of a front or rear axle, and a mechanical member. 1 / 2
