This invention relates to a bench top universal wire recycling system and method and, more particularly, to a bench top universal wire recycling system and method, which may be used to treat scraps of an electrical conductor or wire and remove insulation from metal of the conductor and separate the conductor into insulation and metal. The bench top universal wire recycling system may be adjusted to handle different gages of wire.
Electric wiring is critical for the functioning of any building that requires electrical service. Installing this electrical wiring in order to provide the necessary electrical service for the building requires the services of a trained electrician to position the appropriate electrical conductor properly. The circuits formed by this electrical wiring provide electrical power for the building. Typically, the electrical wire has insulation secured around the elongated metal to conduct electricity as desired. During the course of the wiring project, an electrician will have wire scraps leftover from any electric wiring job. Such wire scraps are waste, which should be recycled. The job may be residential or commercial.
With the increase in the cost of copper wire or other electrical wiring, it becomes critical to efficiently recycle whatever wire scraps there may be. Typical wiring or electrical wire has an insulation coating around elongated metal. Providing metal for the wire to the recycler without insulation thereon approximately doubles the amount of money an electrician receives from the recycler for the insulated wire.
Effective insulation on a wire requires that the insulation be durable and firmly encapsulate the wire. Thus, removing the insulation from the wire is difficult. With the great increase in recycling prices of uninsulated wire, as opposed to insulated wire, it becomes clear that an efficient device for and method of removing insulation from wire for recycling offers great advantages to the electrician trying to efficiently recycle his scrap wire.
Electrical wires come in many different diameters. It can be difficult for wire strippers to efficiently remove insulation from wire scrap. If a bench top universal wire recycling system can be easily adjusted to handle many different sizes of wire, removing insulation from a wire can be accomplished more efficiently.
It is desirable to minimize damage to the metal of the wire itself as the insulation is removed therefrom. Damage to the wire can occur as the insulation is cut in order to facilitate removal of the insulation from the wire. With less damage to the wire, removal of the cut insulation is greatly simplified, and the metal thus freed can be recycled.
Among the many objectives of this invention is the provision of a bench top universal wire recycling system, which may be used to remove insulation from a wire to free up the metal as desired.
A further objective of this invention is the provision of a bench top universal wire recycling system that can easily be adjusted to accommodate various sizes of wire.
A still further objective of this invention is the provision of a bench top universal wire recycling system that minimizes damage to the wire as the insulation is removed therefrom.
These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a bench top universal wire recycling system adapted to remove insulation from electrical wires in order to more efficiently recycle the wire. A lightweight bench top universal wire recycling system, a copper cut fixture is mounted in a housing which supports a wedge blank system. The wedge blank system includes a preset stop block with a modified spring plunger. A custom wedge blank permits large wires or very small wires to have insulation removed or stripped therefrom. The housing includes a blade block system, which allows for micro-adjustments in the wire stripping procedure. The blade in the blade block system has minimal or no contact with the metal of the wire, and efficient contact with the insulation to be removed from the wire.
Reference will now be made in detail to several embodiments of the invention that are illustrated in accompanying drawings. Whenever possible, the same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. For purposes of convenience and clarity only, directional terms such as top, bottom, left, right, up, down, over, above, below, beneath, rear, and front, may be used with respect to the drawings. These and similar to directional terms are not to be construed to limit the scope of the invention in any manner. The words attach, connect, couple, and similar terms with their inflectional morphemes do not necessarily denote direct or intermediate connections, but may also include connections through mediate elements or devices.
To create a lightweight bench top universal wire recycling system, a copper cut fixture for removing insulation is mounted in a housing which supports a wedge blank system. The wedge blank system includes a preset stop block with a modified spring plunger. A custom wedge blank permits large wires or very small wires to have insulation removed or stripped therefrom. The housing includes a blade block system, which allows for micro-adjustments in the wire stripping procedure. The blade in the blade block system has minimal or no contact with the metal of the wire, and efficient contact with the insulation to be removed from the wire to recover and recycle the metal.
When the blade is set to the correct depth, the blade will have very minimal contact with the metal of the wire. A length of wire as short as nine centimeters can be pushed or pulled through the lightweight bench top universal wire recycling system; with pliers, if necessary; to provide a slit in the insulation. The slit permits the insulation to be removed from the wire, so that the metal can be isolated for recycling. A longer piece of wire can be pulled through the lightweight bench top universal wire recycling system with one hand while the other hand removes the plastic or other insulation from wire. Readjustment of the blade may be necessary to facilitate maneuvering of the wire through the lightweight bench top universal wire recycling system.
The bench top universal wire recycling system is precision designed to remove insulation from stranded wire or solid wire by use of the web system with a preset stop block using a modified spring plunger. It can cover wire sizes many types. The wires can be number one gage to 500 MCM cable. Custom wedge blanks can be made for any size of wire up to 500 MCM cable.
When the blade is set to the correct depth, the blade should not touch the copper. However, the blade may contact the copper in some spots. This bench top universal wire recycling system can strip a piece of wire as short as three inches long. The wire is just pushed through the back of the bench top universal wire recycling system. At the wire comes out, it is possible to grab the end wire and pull wire through with pliers, or other appropriate tool. In this way, the installation can be peeled away. With the insulation removed. Recycling value of the wire is about double that of the insulated wire.
With a long piece of wire, it is possible to pull the wire through with one hand and remove insulation with the other. If the blade is set too high, minor adjustment has to be made to get the wire through the bench top universal wire recycling system.

Right thumb screw 164 and left thumb screw 166 hold top plate 160 in position. Blade adjusting block 130 assists in guiding the wire 106 through the assembled wire stripper 102.
Additionally,
Now referring to
Right blade block 120 for bench top universal wire recycling system 100 is joined to left blade block 140. Right blade block 120 and left blade block 140 are substantially similar in shape, but differ in the number of apertures therein. Right blade block 120 has the right blade support 122 capable of working with pivot pin blade 142 on left blade block 140 to support blade assembly 200 therebetween.
Blade adjusting block 130 connects right blade block 120 to left blade block 140 and supports blade assembly 200 between right blade block 120 and left blade block 140. Right blade block 120 and left blade block 140 are rectangular solids with apertures therein and an edge removed therefrom.
Right blade block 120 has a right flat support 124, while left blade block 140 has a left flat support 144. Right flat support 124 cooperates with left flat support 144 to provide a mounting base 146 for the wedge blank 162 and the blade assembly 200. Right flat support 124 and left flat support 144 are each formed by removing a triangular cross section of material from a corner of right blade block 120 and left blade block 140 respectively.
Wire handler is adjusted by wedge blank 162 and its variations—the 14/12 wedge blank gage 162a handles 14/12 gage wire, wedge blank gage 162b handles 10 gage wire, wedge blank gage 162c handles 6 or 8 wedge blank duties, and wedge blank gage 162d handles #3 gage wires.
Blade assembly 200 includes blade 114 supported by blade shim 182. Blade shim 182 assists with the holding of blade 114 in a desired position between left blade block 140 and right blade block 120 in order to permit wire 106 to be passed over blade 114 and have wire coating 118 cut so that metal 108 can be separated from the wire coating 118.
With the addition of
Mounting base 146 can hold right blade block 120 adjacent to left blade block 140 with frame screws 168. A frame screw 168 fits into a threaded relationship with each frame aperture 170. Each frame aperture 170 has a frame bevel 172, so that frame screw 168 will maintain a flat surface for mounting base 146. Frame pins 174 fit into frame apertures 176 to further stabilize the relationship between mounting base 146, right blade block 120 and left blade block 140.
As wire 106 passes between wedge blank 162 and blade 114, metal 108 and wire coating 118 are separated. Right thumb screw 164 and left thumb screw 166 hold top plate 160 in position. Blade assembly 200 cooperates with the bottom blade spacer 112 to support blade 114 on left blade block 140. Spacer apertures 190 receive left block knobs 192 and permit bottom blade spacer 112 to hold blade 114 in a desired position for removing coating 118 from metal 108.
Assembled wire stripper 102 comes with any desired number of wedges. Four wedges, which are particularly useful, include those made for #3, #6, #8, #10, #12, and #14 wire as shown in

As
Extrusion base 207 receives wire 106 by virtue of the large wire pushrod head 206 and large wire push rod handle 208 and directs it to the peel cone mount 205. Clamp collar 209 supports the peel cone mount 205.
From the peel off cone 202, wire 118 is wrapped around a wired shaft 212. If desired, a coarse knurl 214 can assist to recover the metal 108. The shaft 212 is rotatably mounted in two oppositely disposed shaft mounts. There is a first shaft mount 220 and a second shaft mount 222 supporting wired shaft 212. A drill or other suitable device (not shown) can be used to turn the wired shaft 212 and pull the metal 118 through the peel cone 202.
Clamp 209 assists with this mounting and is preferably a 0.5 inch clamp.
In
Electrical wire recycling device 300 permits easy separation of wire coating 118 from metal 108. If a power source 310 pulls the wire 106 from the wire guide 302 over adjustable blade 304 even greater advantages are obtained. Recycling services pay roughly double for uncoated wire as is paid for coated wire. Having such a simple, portable and effective wire stripper provides a great advantage for recyclers and electricians alike.
