(54) AUTOMATIC MACHINE FOR THE MANUFACTURE OF FISHING HOOKS

one

The invention relates to devices for the manufacture of wire parts, in particular for the manufacture of fishing hooks.

Known for the main author. St. No. 230771 fishing hook making machine, including wire feed mechanisms, straightening, lengths, bending, kinematically connected to the ground drive shaft, and a mechanism for transferring the workpiece from one position to another. The machine is equipped with a spike formation mechanism, a flexible ends of the workpiece, a hook formation mechanism, and a mechanism for transferring blanks from one position to another is designed in the form of a screw conveyor and profile guides connecting the flexible ends and the hook formation.

The spike formation mechanism is made in the form of two adjusting cutters fixedly mounted on a brace, two adjustable cutters fixed on the carriage reciprocating from the levers connected to the common drive shaft and a die with a die. the hook is made in the form of a reciprocating movement in the vertical plane of the carriage with hinged levers on it, which bend and crimp the ring, and two punches-prisms, impl stvl constituents turn ends at a certain angle.

From the screw conveyor, the billet is fed into the mechanism of the hook formation by means of a carriage fitted with a fork with legs attached to it, reciprocating along the axis of the screw conveyor.

The disadvantage of the known machine is low productivity.

The aim of the invention is to increase productivity. This is achieved by the fact that the screw conveyor of the workpiece transfer mechanism has grooves located under the hook formation mechanism, which are symmetrical to the feed axis and extend in a plane perpendicular to the conveyor axis.

FIG. 1 shows the kinematic diagram of the automaton; in fig. 2 is a diagram of the hook formation mechanism.

The machine has an electric motor 1 transmitting rotation through the gearbox 2 to the camshaft 3 with cams, the movement of which is transmitted by means of levers to the mechanisms for shaping the hook. The feed mechanism 4 moves the wire 5 from the riot 6 through the square-shaped drum 7 to the flattening position 8 and into the cutting mechanism 9. The screw conveyor 10 iodizes the cut billet to a burr forming mechanism 11 at one end thereof, to a burr forming mechanism 12 at the other end and to the hook end bending mechanism 13 and has supports located behind the hook forming mechanism 14. In this case, the shafts 15 of the screw conveyor have grooves located under the hook formation mechanism that are symmetrical to the feed axis and extend in a plane perpendicular to the conveyor axis.

The machine works as follows.

The wire from riot 6 is fed by the feed mechanism 4 through the topping barbai 7 to the position of flattening 8 and then to the spike formation mechanism 9, in which the pre-bending of the double hook piece is simultaneously performed. Next, the cut billet is fed by a screw conveyor successively to the mechanisms 11 and 12 of forming a burr, to the mechanism 13 of folding the ends of the hook and directly to the hook forming mechanism 14, while the shafts 15 of the screw conveyor, feeding the workpiece to form the hook, are in

in such a position that during the final bending, the hooks are guided along grooves symmetrical to the feed axis.

The proposed improvement of the known device allows to increase the productivity of the automatic machine for the manufacture of hooks by 25-30%.
