MACHINE FOR STAMPING AND/OR WELDING ONTO A BUMPER SKIN

摘要

The invention relates to a punching and/or welding machine for acting on a piece of motor vehicle bodywork that is made of plastics material, the machine having movable punching and/or welding tools, each of which is adjusted to perform a punching and/or welding operation and that are transferred from a waiting position to a working position for performing the punching and/or welding operation, the punching and/or welding operation being performed in three stages:
a) transferring from a waiting position at a distance from a skin of the piece in order to come into a working position in contact with the skin;b) performing the punching and/or the welding; and thenc) returning to the waiting position;

the device further comprising a support for receiving the skin in a determined position. The support and the movable tools are arranged in such a manner that, once the skin has been positioned on the support, it defines, possibly in association with a protective screen, a safety volume within which the movable tools move in order to perform the punching and/or welding operations on the skin.

1. A punching and/or welding machine for acting on a skin of a piece of motor vehicle bodywork that is made of plastics material, the machine having movable punching and/or welding tools, each of which is adjusted to perform a punching and/or welding operation, the punching and/or welding operation being performed in three stages:
a) transferring from a refracted position at a distance from the skin in order to come into a working position in contact with or in the immediate proximity of the skin; b) performing the punching and/or the welding; and then c) returning to the retracted position;the device further comprising a support for receiving the skin in a determined position, wherein the support and the movable tools are arranged in such a manner that, once the skin has been positioned on the support, it defines, possibly in association with a protective screen, a safety volume within which the movable tools move in order to perform the punching and/or welding operations on the skin.
