Description

The invention relates to automatic machine tools for the manufacture of tongues for needles of hosiery and fencing machines, using a common cam shaft for acting with the help of levers on working bodies. In such machines, it is proposed to transfer from the fist eccentrics to the working bodies with one single and four pair of levers pivoting around the horizontal axis.

In FIG. 1 shows the top view of the machine; FIG. 2 is a view of the machine on the right in FIG. 1; FIG. 3 is a section along line AB in FIG. one.,

On the frame / mounted in bearings 3, the shaft 4, driven into rotation from the engine through the pulley 5. On the shaft 4 mounted figure eccentric 7, for the lever 8, and end cam plates / 7 and 76, acting on the ends of the levers 12, 14, 17, 21. The last levers with their free ends set in motion the working bodies of the machine, carrying out the operations of wire feeding, flattening, drilling and cutting. For feeding the wire, there are sponges 13, which are compressed under the action of the ends of the levers 12, the second ends of which run along the curved surface of the eccentric 77, while the translational movement of the jaws 13 is performed by the projection of this eccentric 77, and the return movement under the action of springs 19. The lever 8 (Fig 3), one end of which is under the action of the eccentric 7, serves to transmit the movement of the stamp 7 attached to its other end. The left shoulder of the lever 8 is pressed towards the eccentric 7 by the spring b fixed on the stand 9. The stamp 7 is used to stamp the spoon on the matrix 10. The levers 14, which interact with the eccentrics 77, transmit the ends 75 to the stamps 75, which produce flattening of the wire. The lever 77, interacting with the eccentric 16, feeds the drill enclosed in the chuck 18, at which the workpiece is held while drilling with an abutment with the conductor. The eccentrics 16 are also driven by the levers 21, which at their second ends act on the tool chucks 22 s themselves for cutting and cutting the wire. Cartridges 22 and stamps 75

uncoupled, after releasing them from the action of the levers, by springs enclosed in the recesses in them. When the machine is in operation, the wire is fed between eccentrics 7 and all individual operations are performed in a specific sequence for each individual tongue, and the eccentric curves are made so that all the described operations are performed simultaneously. With each turn of the shaft 5, after cutting the finished tabs with the sponge knives 22/5, the action of the spring J9 is reset to grip the wire and, consequently, the machine continues to work without interruption. The ends of the levers on the eccentric surfaces are adjusted with screws.

The subject matter of the invention.

 Automatic machine for izgoto-. the appearance of tabs for needles in phased machines, using a common cam shaft for acting with levers on barrel organs, characterized in that for the production in sequential order of operations that constitute the process of manufacturing tabs, namely: stamping the spoon, flattening the end , drilling a hole for the closing and cutting into separate tongues, one lever 8, rotatable around the horizontal axis (Fig. 3) with a punch, was used for punching the spoon, and four rotary levers / 2, f4, 17, 21 (Fig. 1) acting on the jaws 13 respectively, for clamping the wire to feed it onto the dies 75, for flattening the end of the spoon on the drill bit 18 and ynojj with a conductor, for drilling a hole for rivet and on the knives 22 for cutting the workpiece.
