Definitions
- the invention relates to a drawing machine with a drawing die and a continuously operating drawing device.
- the object of the present invention is now to avoid the disadvantages of these known drawing machines and to ensure a reliable pull for wire, pipes and / or profiles.
- the drawing device has only one closed drawing element, that this drawing element is guided around axially parallel wheels and is moved in a controlled manner via at least one of the wheels, that the drawing element is connected to clamping devices carrying clamping jaws and that the clamping jaws for detecting a wire, tube or profile to be drawn can be moved towards and away from one another in a controlled manner.
- 1 is a side view of an embodiment in which the traction element is designed as a chain
- FIG. 1 is a plan view of the embodiment of FIG. 1,
- FIG. 3 shows a detail relating to the adjustment of wedge elements to increase the clamping force along the line from A-A in FIG. 1
- FIG. 4 shows a horizontal section through the representation according to FIG. 3 along the line B-B in FIG. 1,
- FIG. 5 shows a section along the line C-C in Fig. 1 with the jaws closed
- FIG. 6 shows a representation corresponding to FIG. 5 with the jaws open
- FIG. 8 shows an embodiment relating to the control of the clamping devices by means of a control cam and return by springs
- FIG. 10 shows a representation similar to FIG. 8 with wedge elements for increasing the clamping
- Fig. 12 is a representation similar to Figure 1 with a device for wire feed and
- Fig. 13 is a drawing machine with open jaws and passing gripper.
- the embodiments of the drawing machine according to the invention shown in the drawings have two chain-like tension elements 3, each of which runs over two wheels 4, one of which is driven.
- the driven wheels 4 sit as well like the two non-driven wheels 4 each on a common shaft 12.
- the chain-like tension elements 3 are each connected to a plurality of clamping devices 6.
- two clamping devices 6 belonging to different tension elements 3 cooperate in order to grasp a wire 7 with their clamping jaws 5.
- the clamping devices 6 have rollers 13 which are guided on control cams 8 due to the movement of the associated tension element 3.
- the clamping jaw 5 of each clamping device 6 is held by means of two holding rods 11 which are passed through the associated chain-like tension element 3.
- the holding rods 11 cause the clamping devices to be driven via the associated pulling element 3.
- cooperating clamping jaws 5 can be moved towards one another via the holding rods 11 without a force acting transversely to the running direction of the tension element 3 acting on the respective tension element 3. That is, the movement of the clamping jaws 5 towards or away from one another is decoupled from the tension elements 3, as a result of which the tension elements 3 have less wear.
- the control cams 8 are designed in such a way that the clamping devices 6 in the beginning region of the upper run are moved towards one another in a manner that detects the wire 7 and towards the end of this run the wire 7 is moved away from one another in a releasing manner.
- wedge elements 9a (see FIGS. 3 and 13) acting on the position of the control cams or clamping wedge elements 9b arranged in the individual clamping devices 6 (see FIG. 10) are provided. Both the wedge elements 9a according to FIG. 13 or FIG. 3 and the wedge elements 9b according to FIG. 10 result in a relative movement when the wire 7 is gripped.
