Description

perpendicular to the direction of the wave-like bending, side view; on 1fig. 3 - the mechanism of separation of the workpiece at the moment of breaking the workpiece from the iMOTtKa (Wire through the notch,

IZY1CH1KOVOYY IGL-Y.

In the proposed device, a coil 1 of the wire is mounted on the coil 2. The correct apparatus 3 receives rotation from the electric motor 4 through the pinion transmission 5. The wire is fed by means of the slider 6 with the clamping device 0 installed on it: OWN CONSTRUCTION.

The slider 6 is controlled through the lever 7 from the drum cam 8 mounted on the camshaft 9.

After the feed mechanism, along the wire, an ilO guide tube is installed, next to which are placed counter V-shaped knives, fixed 11 and movable 12, moved through the crawler 13 from the cam 14 installed on the camshaft 9. Knives S and 12 are designed for notching Circular wire section. After; the knives 1-1 and 12 accommodate a wavy-bending mechanism containing a fixed matrix 15 and a punch 16 mounted on a slider 17 moved from the cam 18 sitting on the shaft 9 in the same direction as the movable knife 12. After The mechanism of the wave-like bending along the wire is set to a press with a flattening matrix 19 and a flattening punch 20 (Fig. 2), with the flattening punch moving from the eccentric shaft 21 of the press in a vertical plane, i.e., perpendicular to the direction of the notch of the wire and wavy bending. From the eccentric shaft 21 of the press through sprockets 22 and: 23 with the help of chain 24 (The camshaft 9 of the device rotates. After the flattening mechanism, the knife bend mechanism is installed (billet of the workpiece containing the bend punch 25 mounted on the slider 26 moved from the cam 27, mounted on the shaft 9. Moreover, this mechanism is installed in such a way that the length of the bent end of the wire is equal to the sum of the length of the (cooking and length of the leg, and the notched section located from the end of the length of the workpiece, also appears in aemom end.

In the path of the bend (the end of the wire 28 (Fig. 3)), a finger 29 is inserted into the mechanism for separating the workpiece from the coil of wire and intended to break the workpiece 30 along the notch. The receiver, which the broken workpiece falls into, is not shown in the diagram.

The wire straightened in the (correct apparatus 3) is fed by a clamping device mounted on (slider 6, through the guide tube LO to the wave-bending mechanism.

At the time of implementation of the wave-like bending with help (Matrix 16 and punch 16

The clamped wire is cut by the opposing V-shaped knives 11 and 12 at a distance from the end, equal to the length of the workpiece with the formation of a smaller section. At the next wire feed, the curved section (including the notch) gets onto the flattening matrix 19 and flattens with the flattening punch 20 in the direction perpendicular to the direction of the wavelike

bending and notching. The reduced cross-section of the notched portion of the wire also flattens, and its area decreases again. After the end of the wire is flattened, the punch 25 of the bend, controlled by the yulach (ka 27, produces a bend.) Of the end of the wire 28, and the bend end includes the entire flattened (by the previous cycle section, including the notch, and at the inflection point

Wire harpoon still has a circular cross section.

When moving, the bend end of the wire hits the finger 29, and since the wire cross section at that place is weakened by a notch and subsequent (by smoothing, the billet is separated from the wire (it is fed to the receiver). loaded into the magazine for further automatic processing. During the flattening of the wire between the punch 20 and the flattening (flattening matrix 19, it flattens and a small portion of the end of the subsequent billet that forms agotovki.

Subject invention

Device for the production of three-piece blanks. Zych (knitting needles from 1mot1k wire (ki containing a frame mounted on the frame and kinematically connected with a cam camshaft wire feed and straightening, wave-bending mechanism in the form of a matrix and SLIP-UP slide, flattening mechanism , mechanism are flexible legs and mechanism of separation

blanks from a coil, characterized in that, in order to improve the quality of the product, the mechanism (flattening is installed successively behind the wave-like bending mechanism and made in the form of a matrix and a slider, the mechanism for separating the needle blank from the skein is designed as installed (according to the wire feed direction. KI in front of the wave-bending mechanism of two notching knives, mainly V-shaped, as well as installed after the mechanism ibki finger legs performed guide fragments zagotonki the notched portion.
