SU31281A1 - Knitting needles tongue making machine - Google Patents

Description

It is proposed in the machine for making knitting needle tabs to flatten the ends of the wire blanks in the planes of one stationary slider and the other, ignoring from the triple eccentric on the main shaft and the springs of the reciprocating motion, the slider with the boomer located in the core, progressively moving from the middle shaft, on the first slider. It is proposed to stamp the spoon in the rolled billet with a chip in the slide with its translational motion to the matrix from the levers and the transmission mechanism from the main shaft with the eccentric, and to cut the ribbon into the tabs with a knife moved by a system of levers and an eccentric on the main shaft.

In FIG. 1 shows the top view of the machine; FIG. 2 is a vertical plane section along line AB in FIG. one.

Flywheel / (Fig. 1) mounted on shaft 2; the shaft runs in bearings 3; there is a tapering gear 5 on it. This gear rotates the gear P, which sits on the shaft W (Fig. 1,2). Shaft 7 (walks

314.

In the bearing 7 /. At the other end of the shaft W sits the gear 16, which rotates the gear 7 / sitting on the shaft 75. This shaft goes to the bearings with the column 19, and the other end of the shaft 78 goes in the holder rack 80. At the very end of the same shaft sits the eccentric 8J . A gear 6 sits on the shaft 2, -the rotor rotates the gear 24 sitting on the shaft 82. This shaft runs in bearings 26. In the middle of the shaft 82 an eccentric 28 sits, which drives the angular follower 29. In this pusher there is an adjusting screw 57. The pusher 29 drives the roller 32. This roller runs in the guide bearing 55 and in the holder rack 80. At the other end of the roller 32 there is a wire feeder 83. Between the bearing 33 of the support holder roller 32 there is a tension spring 34. Under the eccentric 8J there is a driving column 84. This column moves in a guide hole in the frame and has a helical spring 85. In the upper part of the column 54 there is an opening 86 (Fig. 2) . On shaft 2, in the middle, there is

an eccentric 4 that drives the square slider 20. This slider walks in the slide support 87. The slider 20 has a through hole in the center in which the core with the core 88 runs. This core has a shoulder spring inside. At the opposite end of the slider 20, there is a slider 202. This slider runs in the guide cynopre / i. In the protruding plane of the slider, 202, below the center, a hole 89 is made. At the back of the slider 20 there is a bolt 52 which sits in column 100 for adjustment. The gear 24 rotates the gear 58 (Fig. 2). This pinion sits on shaft 56. Shaft 56 runs in bearings 57. There is an eccentric 55 on the same shaft. An eccentric drives rod 35, which goes in column 101 - Rod J5 drives lever 36, which goes in column 101 on the bolt 107. At the end of this lever, there is a bolt 702 for adjusting. A snapshot 36 with a bolt 102 drives the slider 103. This slider moves in the column guide / 07. At the bottom of the slider there is a ram for squeezing the spoons into the tab. On the slider W3, there is a coil spring 104 between the guides of the column 707. The slider 705 places the column 105. At the top of this column there is a matrix with a slot for a spoon. The lever 36 is at one end connected to the spring 37. On the shaft 2, near the flywheel j 7, there is an eccentric (not shown in the drawing) that drives the lever 106. This lever also sets the shaft 45, which runs in the guide bearing 47. At the end of the rod 45, there is a lever 44 that drives the knife 42 into movement. At the other end of the knife there is a coil spring 43. The knife 42 moves in the guide column 41. Against the knife 42 there is a corner bar 38 to which the die 40 is attached , with a hole, as indicated on the drawing (Fig. 1, 2) ..

Before starting the machine, the wire from which the tabs are made is inserted into it. The end of the wire 709 wound onto the coil 705 is threaded into the holes of the holder 80, the feeder 83 and then through the hole 86 provided in column 84. This wire passes between the sliders 20i and 202 and above the column 705 with the matrix. The shaft 2 is driven in rotation by the eccentric 4 and gear 6 vi 8. The gear 6 rotates the gear 24 together with the shaft 82 and the eccentric 25, and the latter drives the pusher 29 together with the adjusting screw 7, the roller 32 and the suppressor 83 (Fig. 1) ..

At the moment when the eccentric 2 drives the pusher 29, and the latter pushes the roller 32 forward with the feeder 83, the tongues 770 held in the pusher clamp the wire and feeds it forward, and when the eccentric 28 releases the pusher 29, the spring 34 having 32 on the roller 32 tilts roller with backfeed. In the holder 80, on the opposite side, there is the same tongue, which holds the wire back during the withdrawal of the feeder.

While the iodan wire is between the front planes of the sliders 20i and 202, the eccentric 4 with its eccentric side a presses the slide 20i, and the latter presses its plane against the plane of the subzun 202 and stings the wire. When the eccentric 4 departs, the slider 20i is pulled back. At the same time, gear 8 rotates gear 9, together with shaft 70 and gear 16, which drives gear 77 together with shaft 18 and eccentric 57; the latter presses the downwardly moving column 84 together with the wire in the hole 86. Thus, the flattened portion of the wire is lowered to the center of the hole 89, located in the projected plane of the slide 20, (Fig. 2). At the same time, the eccentric 4, with its eccentric side, pushes the slider 20, which with its plane presses the flattened wire to the plane of the slider 202; thereafter, the middle part 3 of the eccentric 4 presses the rod with a die 55, which cuts a hole in the center of the flattened wire. The gear 24 rotates the gear 55 with the shaft and the eccentric 55, and the latter raises the rod 55, which: causes the lever 36 to move together with the adjusting bolt 702, which presses

on the slider 103, which falls into the cavity of the matrix, which is located on column 105. In this way, the slider 103 s pushes into the center of the wire and squeezes the spoon near the already flattened part of the wire. Then, the eccentric 4, with its eccentric side 5, releases the slider 20i, and the eccentric 81 allows the moving column 84 to rise upward under the action of the spring 85, and the process is resumed. The fabricated tabs are passed through the opening of the column 101 and the rod 35 to the cutting knife 42 against the matrix 40. When the fed tab completely coincides with the hole of the matrix, the eccentric (not shown) on the shaft 2 near the flywheel / moves the lever 106; the latter pushes the barbell 45 with the lever 44, which, in turn, pushes the knife 42 into the atrium 40 and cuts off the tongue, which falls into the substituted box.

The subject of the patent.
