SU970529A1 - Device for stripping insulation from wires - Google Patents

Description

The invention relates to technological equipment for preparing electrical wires for installation and can be used in the electrical industry.

Known knife for cutting the outer insulation of cables containing a cutting blade, platform and handle til.

A disadvantage of the known device is that using it is impossible to simultaneously qualitatively cut different thickness material, in particular the insulation of cables with variable thickness. In addition, the known device does not provide a transverse cut of the insulation.

Closest to the proposed technical essence is a device for removing cable coatings, containing a circular knife driven in rotation from the drive through a flexible shaft, and adjustable in thickness of the coating stops made in the form of cheeks, beveled on the side facing the cable being processed, a circular knife is located between the cheeks [2].

However, this device does not provide high-quality wire cutting with insulation of variable thickness.

The purpose of the invention is to improve the quality of cutting wires with insulation of variable thickness.

This goal is achieved in that the device comprises a platform with a slot for the passage of a circular knife, made in the form of an elastic bar mounted on a pivot arm mounted in the housing and provided with 10 pins, and an adjustable stop is located on the pivot arm.

In addition, the vibrator is made in the form of a rod connected to a cam mounted on the drive shaft of a circular knife and provided with a groove, the platform being fixed to the rod, the pin located in the groove, and the adjustable stop in contact with the rod.

In FIG. 1 shows a device

2Q in the longitudinal cutting mode of the insulation of the wire ·, in FIG. 2 - the same in the mode of annular incision of wire insulation; in FIG. 3 - same, rear view} n5 fiT. 4 - section aa in figure 1;

_ in FIG. 5 is a section BB in FIG. 4} in FIG. b - section BB in FIG. 4. The device contains a circular knife, 1 (for example, a milling cutter), mounted on the shaft 2. The shaft 2 is connected to the shaft of the electric motor 3 with a bevel gear 4. · ’0 Platform b is fixed to the rod 5.

The lever 7 from the cam 8 and the spring 9 through the pin 10 acts on the rod 5.

A shaft 12 is placed in the housing 11, on which the lever 13 is fixed. On the lever 13 there is a handle 14, an adjustable stop 15 and an elastic bar 16. 5

On the lever 17, mounted on the shaft 12, a pin 18 for the spring 19 is fixed. The motor switch 21 is located in the handle 20. A pin 22 is mounted on the lever 13, and a groove 23 is made in the rod to accommodate the pin 22 in it.

The device operates as follows.

; When the shaft 2 rotates, the disk knife 1 and cam 8 rotate. The lever 7 15 transmits oscillatory motion to the rod 5 and platform 6. The device is configured for longitudinal cutting.

When the lever 13 with the elastic bar 16 is moved to the position shown in FIG. 2, the platform 6 under the action of the adjustable stop 15 rises to a certain size; In this case, the disk knife 1 protrudes 25 relative to the platform 6. on the thickness of the cable coating. The device is set to cross ring cut mode.

If the device between the platform, _n b and the elastic strip 16 to enter the cable and rotate the device around the cable, the cable will cross-cut pokrytiya.Zatem device is converted into longitudinal cutting mode, this requires the lever 13 with the elastic strap 35 goy 16 translate to the home position. If the device with platform 6 is inserted under the outer sheath of the cable and moved along the cable, then a longitudinal section of the cable coating is obtained.

The proposed device can improve the quality of the wire with a variable thickness of the insulating coating.

Claims (2)

The lever 7 from the cam 8 and the spring 9 through the pin 10 acts on the rod 5 In the housing 11 a shaft 12 is placed, on which the lever 13 is fixed. On the lever 13 a handle 14, an adjustable stop 15 and an elastic bar 16 are mounted. On the lever 17 fixed on The shaft 18 is fastened with a pin 18 for the spring 19. In the handle 20 a motor switch 21 is placed. A pin 22 is mounted on the lever 13, and a groove 23 is made in the rod for accommodating the pin 22 therein. The device operates as follows. When the shaft 2 rotates, the disk blade 1 and the cam 8 rotate. The lever 7 transmits an oscillating movement to the rod 5 and to the platform B. The device is set to longitudinal cutting mode. When translating the lever 13 with the elastic bar 16 into position, shown in FIG. 2, the platform b under the action of the adjustable stop 15 rises to a certain size -. In this case, the disk knife 1 protrudes relative to the platform, b. On the thickness of the cable coating. The device is configured for crosscut ringing. EH:; if the device between the platforms b and the elastic strap 16, slide the cable and rotate the device around the cable, a cross-section cut of the cable coating is obtained. Then the device is transferred to the longitudinal section mode, for this you need the lever 13 with an elastic strap 16 to initial position. If the platform device 6 is inserted under the outer sheath of the cable and moved along the cable, a longitudinal section of the cable coating will be obtained. The proposed device allows improving the quality of wire cutting with a variable thickness of the insulation coating. Claim 1. A device for stripping insulation from wires, including a housing in which a drive shaft with a disk knife is located, and an adjustable stop, so that, in order to improve the quality of wire stripping with insulated variable thickness, a slot for the passage of the disk knife, equipped with a vibrator, and a mechanism for pressing the cable to the disk knife, made in the form of an elastic bar mounted on a pivot arm mounted in the housing, and an adjustable stop is located on the pivot arm. 2. The device according to claim 1, characterized in that the pivoting lever is provided with a pin, the vibrator is made in the form of a rod connected to a cam mounted on the drive shaft of the disk knife, and provided with a groove, while the platform is fixed on the rod, the pin is located in groove, and adjustable stop in contact with the rod.
