Description

I

The automat is intended for bending products like mounting loops, anchors to embedded parts, brackets, etc. from metal rods.

A known automatic machine for bending curly articles, comprising a central bending mechanism of a workpiece mounted on a rod and mechanisms of bending of workpiece ends with bending heads symmetrically relative to it, having stop and bending rollers fixed in the housing.

The disadvantage of the known machine is limited technological capabilities.

In order to eliminate this drawback in the proposed machine, each bending head is equipped with a pinion shaft housed in its housing, axially mounted and bearing axially fixed and eccentrically fixed bending rollers, and also a bracket connected to the bending head by means of adjusting elements mounted on the rod with the ability to move along it.

FIG. 1 shows the kinematic scheme of the proposed automaton; in fig. 2 - bending head for bending the ends of the workpiece and intermediate bends of the workpiece; in fig. 3 shows the mechanism of the central bend of the workpiece; in fig. 4 shows a bend from JL

Delhi type

The machine includes the feed rollers 1, the correct roller device 2, the knife 3, the feed mechanism 4 of the workpiece, the mechanism for bending the ends of the workpiece in the form of bending heads 5 and the mechanism of the central bend of the workpiece in the form of bending heads 6 mounted on the rod 7, and the feed mechanism 8 of the rod in the bending zone, installed on the rail 9.

In the housing 10 of the bending head 5 there is mounted a rod-rod I, which is in engagement with the shaft-gear 12. The bending 13 and the stop 14 rollers are fixed to the latter, which are led out of the bending zone or introduced into it

moving the gear shaft 12 by means of a hydraulic cylinder 15. The head housing for moving it and turning around the rod 7 is provided with two symmetrically arranged brackets 16. Each of them is connected with the head housing by an adjusting element in the form of a screw, by means of which the head moves.

Claims (1)

In the housing 17 of the bending head 6, the forming rod 18, the mandrel 19 and the clamp 20 are set, driven by hydraulic or pneumatic cylinders 21, 22 and 23, respectively. The head housing is provided with a bracket 24 for moving along the rod 7 and fastening with a hinged bolt and nut. The machine works as follows. The rod from the coil with the feed rollers 1 is pulled through the correct roller device 2 until it stops, after which the pressure of the feed rollers is turned off and the mechanism of the cutting device 3 is turned on. Next, the workpiece is fed by the mechanism 8 to the bending zone, where it is first pressed by the head 20 and then bends. In the folding of an L-type product, only the head b, products of type / / / / /, and so on, take part - head 6 and two heads 5, products of type, etc. - all five heads. Claims of an automatic machine for bending curly articles containing a central bending mechanism of a billet mounted on a shank and mechanisms of bending of the ends of a billet with bending heads that have resistant and bending rollers fixed in the housing symmetrically with respect to it, in order to extend the technological capabilities of the machine, each The bending head is equipped with shaft-gears placed in its housing, mounted with the possibility of axial movement and bearing resistant and equi-axially mounted with it centrically bendable bending rollers, as well as a bracket connected to the bending head by means of adjusting elements mounted on the rod to move along it.   B, p: Y- -1 13, -20 21 N Tjr ° ort °
