SU460592A2 - Wire Stripper for Isolation - Google Patents

Description

one

The main author's certificate No. 272410 describes a device whose working body is made in the form of a rotating disk with an open groove for inserting the machined wire and two symmetrically arranged relative to the groove of the spring-loaded sectors that turn their axes iBOKipyr during the rotation of this disk and forming the working firing zone, twisting and stripping insulation, just one of the sectors is made with an electric burner, and the other with a non-sharpened knife.

This device provides stripping of wires of unlimited length and anywhere in the wire and can be used for installation and assembly work in hard-to-reach places of radio and electrical equipment.

However, the known device has drawbacks that imply the possibility of failure of the sectors and the unreliable seizure of the treated wire when it is contaminated and the presence of insulation in the working area.

The aim of the invention is to eliminate the indicated disadvantages.

This is achieved by performing a drive in the form of a worm gear pair, containing a split wheel with sectors installed on it, one of which is equipped with a leash that interacts with a screw or with a fixed copy depending on the position of the screw. The drawing shows the described device.

The worm to 1. During the working movement is engaged with the split worm wheel 2. Inside the worm wheel there is a sector 3 with a kiln and a sec T0 | p 4 with a knife on its axes. The leash 5 is fixed on the sector with the burner n, the exit from the groove of the worm gear, it contacts the worm. The worm wheel is mounted in case b with a cam 7 fixed on it. The device is turned on by the lever 8.

The device works as follows.

The motor is turned on, turning the worm to 1. The treated wire is inserted into the slot of the device. When pressed on the lever 8, the burner is connected to the current source and breaks up, the worm to 1 engages with the worm gear 2, causing it to rotate with the sectors. The leash 5, rotating with the wheel, hits the copier 7 and turns the sector supplied with the killer.

3, which, together with sector 4 with a knife, compresses the wire being processed, and the burner burns through the groove in insulation along the perimeter. When pulling processed

wires from the device — when the sectors rotate, the wires tend to twist and the insulation is impeded. When the work is completed and the lever 8 is released, the latter, under the action of the gun, at the moment of coincidence of the groove of the wheel 2 with the protrusion of the lever, returns to a "similar position. The lever 8 releases the worm to 1, which is disengaged from the worm gear 2 and, thanks to the continued rotation, brings sector 3 beyond the leash 5 to its original position.

Subject invention

Device for stripping wires from software ABOUT. No. 272410, characterized in that, in order to ensure reliable gripping of the wire being processed and turning the sectors, the drive is made in the form of a worm gear containing a split wheel with sectors installed on it, one of which is equipped with a leash that interacts with a worm or fixed copier e depending on the position of the cipher.
