Joining device for connecting parts to be joined in a stamping process comprises a stamping unit having moving concentric stamps

Joining device for connecting two sheets, has cutting template with conical shaped retaining region for receiving punched out piece that is punched out by co-operation of punching unit with cutting template

Sheet i.e. body sheet, folding method for motor vehicle, involves producing fold by bending edge area of sheet around edge of another sheet, and pressing bent edge area of former sheet into passage during form joining by forming punch

Method for joining parts arranged between a die and a stamp using a semi-hollow rivet comprises not breaking through the joining part assigned to the die during joining so that a residual base remains between the rivet and the die

Component-arrangement for motor vehicle, has bolt-like functional element comprising ball-shaped head inserted into recess in form of snap connection such that functional element partially project outwardly from components

Arrangement for connecting components e.g. metal sheets for motor car, has clinch connection element that is made by joining tool which is arranged partially in metal sheets and is projected partially to outside region of metal sheets

Thin sheet joint manufacturing device, has embossing contours forming flange and reinforcing structure of sheet joint, and embossing contours formed on single-piece embossing tool, and cutting contour forming through hole enclosing flange

Fastening arrangement for fastening e.g. roof unit, to roof frame part of passenger motor vehicle, has body component and body unit connected with one another by connection, where space for connection is provided in area of shell

Metal sheet joint manufacturing method, involves forming collar by deformation at thin-walled material, where collar is formed for accommodating screw profile, and forming reinforcement profile surrounding collar at thin-walled material

Joint making method for sheet metal, involves providing sheet metal with thickness lesser than preset percent of nominal thread diameter of flange or thread screw, and forming flange by forming die using extrusion press
