Description

one

The invention relates to electrical engineering and can be used to prepare electrical wires for installation.

The purpose of the invention is to simplify the design.

Fig, 1 shows the device, a general view; in Fig .. - section aa in figure 1; Fig. 3 is a sectional view of B-Bnafig. 1 in Fig. 4 is a diagram of the initial position of the wiper blades of the stripping mechanism; Fig. 5 is a diagram of a stripping of the insulation with stripping knives; Figure 6 is a stripping circuit for stripping knives; Fig. 7 is a fabricated wiring diagram.

The device for the pre-installation preparation of the electric wires comprises a mechanism 1 in isolation of the insulation removal from the ends of the wires 2, a mechanism for forming a spiral, a mechanism 4 for cutting the wires.

All these mechanisms are connected to a common drive (. Not shown) by means of the working shaft 5 and are mounted on the bed 6.

The insulation removal mechanism 1 from the ends of the wires consists of a connecting rod 7, having an eccentric 8 at one end, knives 9 secured by stripping rods and having the possibility of being adjusted to a predetermined size. The other end of the connecting rod 7 is chardically connected to the slider 10, which moves freely in the sleeve 11 mounted on the frame b. The carrier 12 is rigidly fixed on the working shaft 5 and placed inside the eccentric 8. With its ROLLER 13, the carrier 12 interacts with the eccentric 8, which has a closed loop with a variable cur. visa,

At the same time, geometrical parameters 5 Movement along an eccentric, is encountered

when interacting with the carrier, the eccentric contours provide technologically necessary working strokes mutually perpendicular to each other in the following ratio:

with the straight part of the eccentric and informs the knives horizontal movement, at which the incised insulation is pulled off from the end of the gQ wire (Fig. 6).

H is the vertical stroke of the knives, which provides an incision of the insulation; L is the horizontal stroke of the knives,

providing isolation removal from the end of the wire; R is the radius of the working circle of the eccentric equal to the radius

described circumference drove.

The helix formation mechanism 3 consists of a cone coil 14 having a restrictive shoulder 15 on one side and a groove 16 on the other. The coil 14 is rigidly fixed on the working shaft 5,

The mechanism 4 pieces of wire consists of cutting knives - movable 17 and fixed 18 mounted on a rack 19 mounted on a bed 6.

The movable knife 17 is rigidly connected to the Shaped bar 20, which interacts with a 2G roller, driven 22, rigidly seated on the working shaft 5,

The proposed device is intended to perform several technological operations that are included in the preparation of electrical wiring schemes, including wires of different cross section (Fig. 7), and operates in the following way.

In order to remove the insulation, the end of the electric wire is fed to the mechanism 1 up to the stop 23 fixed on the slider 10 and fixed by the clip 24 mounted on the frame 6.

Wiping knives 9 with a connecting rod 7 are in the initial positions (FIG. 4), the roller 13 of the carrier 12 interacts with the eccentric 8,

When the drive is turned on, the carrier 12 receives rotation from the working shaft 5, the roller 13 rolls along the arc-shaped part of the eccentric and transmits the movement to the blades, moving them vertically downwards. The knives, moving by the value of H, cut into the insulation and their vertical movement is stopped (figure 5). Then roller 13, continuing

Eccentric movement encountered

with the straight part of the eccentric and informs the knives horizontal movement, at which the incised insulation is pulled off from the end of the wire (FIG. 6).

By a subsequent movement along the eccentric, the roller brings the knives to their original position, and the mechanism is turned off.

The formation of the helix is as follows.

The end, or the section of wire intended for the helix, is threaded into the groove .16 of the coil 14, the drive is turned on and the helix is wound for the required number of turns. After that, the mechanism is turned off, the formed helix is removed from the tapered part of the coil and transferred to the next technological operation (not connected with this device, for example, wrapping the helix into a plastic box, etc.)

After performing all the technological operations of preparing the wiring diagram, the wire section is produced by the mechanism 4. In the initial position of the mechanism, the roller 21 is driven by the single drive. The device allows the manufacture of wiring schemes that include wires of different cross section in f.
