Description

The described invention relates to multioperational automatic machines for the manufacture of knitting needles and other similar products, made in the form of a number of shaping mechanisms, served by an automatic feed line, with its automatic feed for transferring blanks.

Compared with the known automata of the same designation, with screw rollers for interoperability, transporting the billets, the features of the described automaton design, which provide an increase in productivity in the absence of unreliable mechanisms that perform fast reciprocating movement, are:

a) the execution of transport screws 1x rollers with annular coils at the ends, indexing the loading position of removing workpieces from the rollers, the manufacture of rollers at intervals against the formative mechapisms;

b) the presence of the mechanism of the irenose of blanks in the gaps, with stops on the axes of the formative mechapisms.

FIG. I is presented in an isometric view of the kinematic diagram of the automaton; in figures 2, 3, 4, 5, 6, and 7, the various positions of the mechanisms of the automaton when they shift workpieces.

The machine is driven by an electric motor / belt 2 through a shaft with a worm .j on a worm gear 4, mounted on the main shaft, Fr.

From shaft O, rotation is transmitted through pinion 6. 7 and 6 to shaft .9,

transmitted to shaft 13.

The screw rollers 14. are driven in a motor from the shaft 9 by a chain through sprockets K) and 16 spur gears 17, J8, 19, 20, spd P1, imp on the screw rollers.

Driving a pincer grip. fortified nn slider. and feeding the product for processing, is produced from the cam 3 via a lever. Clamping the grip of the product is carried out by. The release of the grip occurs under the influence of unor 2 during the return movement of the slide 22.

Rail with spring clamps and located on the same rack. moves back and forth along the rollers 14, between them, receiving movement from the axial cam i6 che. pin 2, lever 30, slider and pin i) :, attached to the rail.

Vertical movement of the rail is carried out by two cams 33, sitting on the shaft -5, through the levers / W and the stands with the guides 35.

The drive of the forging head 36 is driven from shaft 3 by reamer 37. The movement of the presses, 5.9 and 40, comes from the jaws —.//– through the levers 42.

The rotation of the incisal head 43 of the poke; is removed from the shaft J by the belt 44.

The work of the machine proceeds in the wake of Yup, in the image.

The blanks 45, laid on the platform 4 (), are fed by a slider (not shown) to the pusher 47, which moves vertically by the lever 48 from the cam 4 and pushes the blanks alternately into the grooves of the screw rollers 14, but by which the blanks are moved to the forging head 36 and other operations. From the rollers, the workpiece removes the left spring clip 50 located on the rack of the rail 27, and raises them to the feed level for the operation, where the workpieces are picked up and clamped by the clamp 2 / and after the rail 27 is lowered, it is processed.

After the operations, the blanks are returned by the gripper 21 to the initial position, after which they are picked up by the right spring clip 51, which, moving from the bar 27 to the right and down, lays the blanks into the grooves of the screw roller.

Finished products are provided with screw rollers evenly on pad C) 2.

FIG. 2 reproduces the supply of pincer grippers 21 to the processing of the workpiece 4.5.

FIG. Figure 3 shows the moment when the left spring clip from the rollers was removed, the next workpiece -56 was lifted to the level of the machining tools, and the right spring clip captured the previous workpiece y5g / clamped by the claw 21.

FIG. 4 shows the withdrawal of the grip 21 to the rear position and the release from it of the workpiece L5.

FIG. 5 depicts the supply of the next billet 4th left spring clip to the grip 21, alternating rail 27 to the right.

FIG. 6 reproduces the approach of the grip 21 to the next billet 46.

FIG. 7 and the moment of insertion of the rail is shown, 7 down, releasing the workpiece 46, clamped in the grip 21, with the left spring clamp, and laying the workpiece 55 on the screw rollers with the like spring clamp.
