SU31280A1 - Machine for the final bend of a pre-prepared knitting needle tail - Google Patents

Description

It is proposed in the machine for the final bending of a previously prepared knit needle tail to use one fixed and four horizontally movable dies fixed to the sliders, shifted by a gear system, shafts and eccentrics from the main shaft for successive bending of the workpiece.

In FIG. 1 shows the top view of the machine; FIG. 2 - side view of the machine with a section of the upper board of the bed; FIG. 3 - Machine bottom view.

The machine consists of a flywheel 7 (Fig. 3) with a protrusion, automatically turned on and off by a lever 3, which is activated from a foot pedal. The flywheel sits on the shaft 4, the rest is located on the sub-holders.5 attached to the lower part of the frame by bolts 6. Gear 7 and eccentrics 8 and 9 with projections W, driving the levers 7 / and 72, are mounted on this shaft, on which there are rollers 75 and M. On the shaft 75, supported by bearings 75 and 77, fastened with bolts 8, the levers 77 and 72 are seated. On the short shaft 20,

inserted in the bearing 27, attached with bolts 22, sits gear 19; a gear 23 (Fig. 2) is coupled to it, sitting on a shaft 24, which also carries a bevel gear 25. Shaft 24 rests on bearings 26 fastened with screws 27. Bevel gear 28 sits on shaft 29 together with eccentrics 30 a 31 gear 32. The shaft 29 has a coupling 35 at the end and rests on the bearings 33 attached by bolts 34 (bolts are screwed into one of the bearings from the bottom, why the bolt is not visible in Fig. 1). All bearings have lubrication holes. On the shaft 37 there are: a bevel gear 36, eccentrics 38 and 39, fastened with screws 40, and an eccentric 4J, on the protrusion of which there is a stop screw 2 for attaching to the shaft. The shaft rests on bearings 43, fastened with screws 44. Next, there is a pusher 45, which sits on a bolt 46 screwed into the bed protrusion. The pusher 45 has a JOO roller at one end (Fig. 2), which sits on a roller 47 attached by a nut, and at the other end

a plate attached to the pusher by two screws 50. The pusher acts on the slider 5 / (Fig. 1) moving along the guide 52 attached to the frame by screws 53. This slider has a bar 54 at one end, and a spring 55 at the other end, attached to a helical rack 55. The rollers 55 and 59, which sit in the guides 60 vi 61 vi, have springs 62 and 63 (Fig. 1). The roller 5 is attached to a slider 64, which moves along one part of the supor 65 attached with screws 66. The slider 64 has a die 104 at its working end serving to bend the needle. A roller 59 is attached to a slider 67, which moves along the second part of the supor 68 along with a platen 69, which also runs along the guide 70, with screws 71 fixed to the stantium. The plate 69 has a protrusion 72 at the end corresponding to the bend shape of the tail of the needle. The plate 73 is fastened with screws 74 to a bed having a recess 75 on the inside corresponding to the shape of the tail of the needle. On the plate 69, there is a stand 76 on which the diverter 77 is pumped, having at its other end a spring 78 attached to the slider with a 7P pin. The slot 80 in the frame is made for dropping bent needles. Soup ort 81 is fastened with screws 82 to the bed. V. This caliper walks the slider 83, which at the working end has a plate 54, which serves to bend the tail of the needle to the desired shape. At the other end of the slider there is a roller 55, and next to it there is a roller 86, which sits in the slider under the bed. The springs 87 and 55 are attached to the sliders 83. Next, there is a guide 89, fastened to the frame with screws 90, in which a slider 91 bent at two right angles goes with a spring 92 attached to it. At one end of the slider 91 there is a roller 93 attached screws 95 to the bed of the rail 94, in which the slide 96 runs. This slide has a roller -P7, which sits on the end of the slide that is bent upwards. Then there is a slider 98, bent at a right angle. Thrust bolt 99 with locknut is screwed into it.

The machine automatically produces four final bends of different shape automatically.

The machine is powered by a motor or a common transmission with a flywheel belt. The position of the semifinished product in the socket 101 (Fig. 1) is applied to the foot pedal through the socket W2 (Fig. 2). The lever 3 at this time rises and allows the key, which is sitting on the ledge of the flywheel 2, under the pressure of the spring (in hell, not shown) to be included in the working shaft 4 (Fig. 3). Due to this, the shaft begins to rotate and drives all parts of the machine. An eccentric 5 (fig. 3) drives the lever 11 (1), which presses the roller 5P moving in the guide rail b /. In this way, the slide 67 is moved together with the die 69, and the semi-finished product is pressed against the die 75. The eccentric P (Fig. 5) drives the lever 12 (Fig. 1), which by pressing the roller 55 moving along the guide 60 , drives the slider 64, moving in the sup 65, the rake W4, at the end of the slider 64, while pressing on the compressed semifinished product and bending at a right angle. At the same time, gear 7 (FIG. 3) transmits movement to gear 19, and this one rotates gear 23 (FIG. 1), the rotating shaft 24 and with it the bevel gear 25. This latter rotates gear 25 with the shaft 2Р and eccentrics 30, 31 and gear 52. The gear 32 rotates the gear 36 together with the shaft 57 and the eccentrics 38.39 liters 41. The eccentric 41 drives the pusher 45 by means of the roller 100. The pusher 45, in turn, acts on the crawler 57 yugia 52 This slider has a protrusion 54 at the end for the production of the bend of the needle tail under the y Glom 45 °. The eccentric 31 pushes the slider 96 by means of a roller P7. The slider 96 moves along the guide 94 and retracts the slider P5, which moves in the guide located under the frame, and has a protrusion at its end (not visible in the drawing because of the plate 75). This protrusion, by squeezing, connects the bends made earlier. Prugeia 106, pressed with screw 107 (Fig. 3), presses the slider 98 to the plate 73 (Fig. 1); the coil spring 705 removes this slide after the process has been performed. At the same time, the eccentric 39, by means of the roller 85, pushes away the slider 83, which runs in the port 81. This slider-83 has the corresponding form 89 at the end and produces the final bend of the tail section. The eccentric 38 drives the slide 105 by means of a roller 86 (FIG. 1). This slider walks in a guide and at its end has a blade shape. By this end, it is wedged between the wall of the bed and the slide 98, freeing the needle. The die 77 is attached to the die 69 on the stand. This part is set in motion when the die 69 and the slider returns 57 under the action of the spring 62.

The eccentric 30 (Fig. 1) performs the work of dropping the needle through the slot 80. Rotating on the shaft 29, the eccentric 30 B moves B through the roller 93, the slider 91 (Fig. 1), which goes along the guide 89. This slider 91 , as soon as the cloak begins to move away 69 Gfig, 5), will fall into place

finding the bent needle in the slot 109 and, having captured the needle together with the die 69, returns to slot 80, through which it drops the needle.

The subject of the patent.
