Description

The invention relates to the field of mechanical engineering and can be used to feed a wire into a groove of a complex shape of a workpiece. A device for feeding wire blanks is known, which includes a rotary table, a rotary conveying mechanism arranged in the form of a shaft, carrying cams, split sleeves and springs for fixing the wire, mounted on a rotary table on a fixed base 1. The known bar also the correct-setting device 2 is consistently installed on the bed unwinding, right-feed and cutting mechanisms, the latter is designed as mounted on the shaft from eznogo disc on which is fixed to also obtochna, sharpened end of the wire guide head, and the cutting mechanism housing is movable in the direction of wire feed axis. After unwinding from a coil, straightened and cut into pieces of a given length comes out straight from the known fixing device, due to the absence of structural elements acting on it and forcing it to move along a certain trajectory. This does not allow to automate the process of wire laying. in the groove of a complex configuration, made on the workpiece. The aim of the invention is the expansion of the technological capabilities of the device by ensuring the laying of the wire in a groove of a complex configuration, performed on the treated child. For this, the device is equipped with a table floating in the horizontal plane, which is pivotally connected with a copier having a groove identical to the groove of the part and a clamping mechanism equipped with rollers fixed above the table, as well as a guide tube whose receiving end is located at the exit of the cutting mechanism, and the lower end is fixed above the table in the place of installation process details. The guide tube has cuts through which the additional feed rollers come into contact with the wire. The floating table consists of two plates, moving one relative to another due to

The body of the roller, installed under the X1 of them.

FIG. 1 shows a device; a general view; in fig. 2 shows section A-A in FIG. one.

The correct-setting device contains a bed 1, inside of which an unwinding mechanism is installed, consisting of roller 2 and drum 3 with coil of wire 4; a correct feeding mechanism, made in the form of regular rollers 5 and feeding sector rollers b, connected by a gear 7 to a cam 8 of the cutting mechanism, which also includes a knife 9 equipped with a spring 10 and a hole for the wire, with one side of the knife bevelled and forming a cutting edge .

At the exit of the cutting mechanism, a guide tube 11 with cutouts is inserted into which feed rollers 12 are inserted, which place the wire in a groove (Fig. 2) of a complex configuration, which is made on the workpiece 13 fixed on the floating table. The latter consists of plates 14 and 15 mounted on balls 16, in which the finger 17 of the hinge mechanism 18 comes in, the copying finger 1 of which fits into the groove (figure 2) of copier 20, whose profile is identical to the groove profile of the workpiece.

Above the floating table is fixed clamping mechanism, made in the form of a pinch rolls 21.

The device works as follows.

The wire 4 is unwound from the coils fixed on the drum 3 by means of roller 2, and enters the correcting mechanism, in which the passage between the rollers 5 is straightened and enters the gap between the feed and sector rollers 6 (both rollers are made leading).

For one turn of the sector rollers 6, a portion of a predetermined length of the wire 4 is fed into the hole of the knife 9 and cut with its cutting edge of the knife 9, which moves to the left of the cam 8 connected to the sector rollers by gear 7, squeezing the spring 10.

Next, the length of wire 4 falls into the guide tube 11, from which, by means of additional feed rollers 12 entering the recesses of the latter, is fed into the groove of a complicated configuration for processing. do ... 13. By entering it, the wire slides along the groove until its force against the walls is sufficient to activate the hinge mechanism 18 and the copying finger 19, which slides along the groove of the copier 20,

The plate 14 with the workpiece 13 fixed on it moves relative to the plate 15 and the bed 1 on the balls 16 along a path repeating the contour of the groove on the part 13 due to the fact that it is copied by the copier groove 20 in which the copying finger 19 moves, transmitting the movement through the hinge mechanism 18 and the finger 17 onto the plate 14. Thus, the entire groove of the part 13 is filled with wire 4. The pressure rolls 21 press the wire laid into the groove during operation of the device.

After laying the wire into the groove on the workpiece, the latter is removed from the floating table and fixed next in such a way that the outlet of the guide tube 1 1 is strictly opposite the groove and also the hinge mechanism 18 is reset. rotation of the sector rollers 6, and the cycle of operation of the device is repeated.

Due to the fact that the device is equipped with a floating table, an articulated mechanism, a copier, a guide tube and pressure rollers, it is possible to fully automate the laying of the wire into a groove of a complex configuration that was previously done manually. This makes it possible to increase productivity, improve working conditions. .
