Definitions
- a wire bending machine of this type is u. a. known from CH-A-592 481.
- the machine described therein has the particular disadvantage that the bending mechanism cannot be adapted to different wire or rod cross sections, as is necessary, for example, when bending reinforcing bars in accordance with SIA standards.
- the rapid changeover of processing to different bar cross-sections is a requirement for the economical use of such machines.
- a plurality of openings for receiving the bending mandrel are distributed at different intervals in order to adjust the radial position of the bending mandrel over the bending plate.
- a cover plate with a radial recess for the bending mandrel preferably has a position-determining element which allows the angular position of the bending mandrel to be determined. With two sensors, which respond to the position determining element, an initial angular position can be determined in this way for each radial position of the bending mandrel on both sides of the wire feed device.
- a method for its operation is characterized in that the bending mandrel is moved back in one of its two initial angular positions after execution of a bending in the retracted position and with simultaneous wire feed.
- the bending mandrel 3 can be withdrawn from its working position.
- the axial displacement of the fastening disk 6 takes place via an oil-hydraulically driven lever system (not shown).
- the torque required for the bending is exerted by the bending plate 4 on the bending mandrel 3.
- the bending plate 4 has a hollow cylindrical rear attachment, on which a drive gear 9 is seated between bearings 8 and is driven by a kinematic chain, which is not shown in detail. In this way, the mandrel can independently perform a circular movement and an inward or outward movement. This will be explained in more detail later in connection with FIG. 5.
- FIG. 4 in front of the bending and shearing point 1 there is first a straightening and transport device 34 consisting of several rollers, which is only shown schematically. This device straightens the wire material drawn off a roll and ensures its controlled feed. The straightening and transport device is followed by a length measuring roller arrangement 35. This determines the exact amount of the feed for the control device of the machine. The The legs and section lengths of the wire brackets to be produced are determined solely by the size of the feed, as can now be seen from the individual phases of a typical operating sequence shown in FIGS. 5a to 5x for forming an S-shaped bracket. According to FIG.
- the desired feed which, as mentioned, is controlled by the length measuring rollers 35, is then actuated by the shear and ejection device 10 (FIG. 5v).
- the sequence ends with the retraction of the shaving head (Fig. 5w) and the insertion of the mandrel (Fig. 5x).
