Claims
- 1. Apparatus for making hollow bodies, preferably components constructed from blanks, comprising a press table; a slide movable upwardly and downwardly relative to the press table; a tool upper part formed as a draw matrix and connected to the upwardly and downwardly movable slide for joint movement therewith; a two-part tool lower part fixed on the press table; additional tools integrated in the apparatus; and a pressure medium supply system in the form of a docking system integrated in the tool lower part,wherein the tool lower part is laterally overlapped by the tool upper part and consists of an auxiliary tool formed as a draw ring and a draw punch guided in the draw ring.
- 2. Apparatus as claimed in claim 1, wherein mutually facing surfaces of the tool upper part and the tool lower part form a negative mold of a component to be produced.
- 3. Apparatus as claimed in claim 1, wherein the docking system has an outwardly and inwardly movable lance, and a connection to a medium reservoir.
- 4. Apparatus as claimed in claim 3, wherein an end of the lance is in the form of a mandrel.
- 5. Apparatus as claimed in claim 1, wherein the docking system is a stationary docking system having a connection to a medium reservoir.
- 6. Apparatus as claimed in claim 1, further comprising at least one punching device integrated in one of the tool parts.
- 7. Apparatus as claimed in claim 1, wherein the draw ring is provided with a collar directed towards the tool upper part.
- 8. Apparatus as claimed in claim 7, wherein at least one filling docking position is provided in the collar of the stationary draw ring.
- 9. Apparatus as claimed in claim 7, further comprising a bushing yieldingly mounted in the collar and having an internal screw thread to receive a hollow screw having a conical widening head shaped to correspond to a countersink in the bushing.
- 10. Apparatus as claimed in claim 9, wherein at a transition at a front end between the bushing and the draw ring collar, a blank resting thereon has an embossed edge formed as a shear edge by an internal pressure.
- 11. Apparatus as claimed in claim 1, further comprising at least one venting docking position and at least one filling docking position.
- 12. Apparatus for making hollow bodies preferably components constructed from blanks, comprising a press table; a slide movable upwardly and downwardly relative to the press table; a tool upper part connected to the upwardly and downwardly movable slide for joint movement therewith; a two-part tool lower part fixed on the press table; additional tools integrated in the apparatus; at least one auxiliary tool integrated in one of the tool parts; at least one upwardly and downwardly movable punch for flanging or edge folding provided in the tool upper part; and at least one horizontally movable pressing punch extending along the whole length of an edge of the blank and provided in the tool lower part.
- 13. Apparatus as claimed in claim 12, further comprising punches for clinching.
- 14. Apparatus as claimed in claim 13, wherein the clinching punches are mounted in the at least one horizontally movable pressing punch and are movable relative thereto.
