Description




FIELD OF THE INVENTION




The present invention relates generally to an apparatus and method for removing coating materials from tubing. More particularly, the present invention relates to an apparatus and method for removing a protective coating from steel tubing.




BACKGROUND OF THE INVENTION




In the automotive industry, brake line tubing is manufactured and sold for installing and replacing brake line tubing in vehicles. For example, it is necessary to replace the brake line tubing of a vehicle, when the brake line tubing corrodes. Corrosion to brake line tubing may be caused, in part, by its exposure to elements such as water, salt, and other substances, which may be on the surface of roads.




Over a period of time, the exposure of the brake line tubing to elements, such as water and salt, may cause the brake line tubing to corrode. Recently, some manufacturers of brake line tubing have been coating the brake line tubing with a protective material, such as vinyl or plastic. By adding the protective coating, the brake line tubing is not as susceptible to corrosion, and the life-time of the brake line tubing is extended.




When repair of a braking system involves replacing a portion of the brake line tubing, a portion of the brake line tubing is removed and replaced by a new portion of brake line tubing. If the replacement brake line tubing has a protective coating, such as vinyl, a portion of the vinyl has to be stripped from the tubing to form a connection with the remaining components of the braking system.




The process of replacing brake line tubing, with the brake line tubing that has a protective coating material, involves: 1) removing the existing brake line tubing; 2) removing a portion of the protective coating from the replacement portion of brake line tubing; 3) sliding on a threaded flare nut/screw fitting; 4) flaring the brake line tubing by spreading or widening the tube, so the flared portion of the brake line tubing can be utilized to create the sealing surface with another component of the braking system, such as the master cylinder; and 5) screwing the flare nut with the corresponding nut/screw of another component of the braking system.




However, problems may occur in the step of sealing the brake line tubing to another component of the braking system. For example, if the plastic coating is not adequately stripped from the brake tubing, it will be difficult to create a flare on an end of the tubing, that is adequate in quality. In addition, if the brake line tubing is not adequately stripped, then the undesirable plastic coating, remaining on an end of the tubing which has been stripped for flaring, may destroy the quality of the sealing surface between the flare and the other component of the braking system. If the sealing surface is not tight, then the brake fluid, which travels through the tubing, may leak through the sealing surface.




Accordingly, it is desirable to provide a tool for adequately removing a portion of protective coating material from steel tubing. Further, it is desirable to provide a tool for removing a variety of lengths of a protective coating material from steel tubing. In addition, it is desirable to remove an amount of protective coating material efficiently and precisely.

and


110


. The fasteners may be pins, screws, etc. In

FIG. 1

, pins are utilized for fasteners


100


and


110


.





FIG. 2

provides another view of the above exemplary embodiment of an apparatus for removing coating material from tubing, in accordance with the present invention. As illustrated in

FIG. 2

, the blade


20


attaches to a slider


40


by a fastener


30


. The fastener


30


may be a screw. The blade


20


may be a single-end blade, in which only one edge is sharpened, or a double-end blade, in which both ends of the blade are sharpened. As shown in

FIG. 2

, the blade


20


is a double-end blade. The two sharpened ends of blade


20


are blade end


120


and blade end


130


. Blades ends


120


and


130


may differ in size. As shown in

FIG. 2

, blade end


120


is smaller than blade end


130


. The blade ends


120


and


130


are utilized to strip a portion of protective coating material, such as plastic or vinyl, from steel tubing. For example, a blade end may be 0.25 inches in length and utilized to strip 0.25 inches or less than 0.25 inches of a coating material from tubing. In another exemplary embodiment of the invention, the blade end may be 0.38 inches in length and may be utilized to strip 0.38 inches of a protective material or more from tubing. It should be understood that a blade of any length may be utilized to strip an amount of protective material that is more or less than the length of the blade. It should be understood that the coating material may be of any material or structure. It should also be understood that the tubing may be hollow or non-hollow and made from any material and may vary in structure.





FIG. 2

also provides a detailed illustration of the tool body


60


according to the exemplary embodiment. The slider


40


is slidably positioned within a first wall


140


and a second wall


150


of the tool body


60


. Further, as shown in

FIG. 2

, the slider


40


, the slider support


50


, and rollers


80


and


90


, which constitute a support structure for the tubing, are located between the first wall


140


and the second wall


150


. Groove


145


and groove


155


are utilized to accommodate the slider support


50


with the first wall and the second wall, such that the slider support


50


is slidably positioned between the first wall


140


and the second wall


150


, such that the slider


50


can be raised and lowered by the adjuster


70


. The adjuster


70


and slider support


50


are a raising and lowering means.




Referring to

FIG. 3

, during operation of the stripper tool


10


, the tubing (not shown) is placed between two rollers


80


and


90


and against the shoulder portions, for example, rims


160


and


170


of rollers


80


and


90


, respectively. The adjuster


70


is utilized to move the positioning of the slider


40


, and can be used to move the slider


40


and blade


20


toward the tubing (not shown).




To remove the protective coating material, such as plastic or vinyl, from the tubing, the blade


20


should be positioned, by utilizing the adjuster


70


, such that the blade


20


, preferably, slightly pierces the tubing. The stripping tool


10


, in its entirety, should be rotated around the tubing, until the protective coating material is removed or removable from the tubing. While rotating the tool


10


around the tubing to remove the protective coating material, it may be necessary to move the blade


20


closer to the tubing. For example, it may be necessary to adjust the blade


20


if the tubing is not positioned securely between tubing, rollers


80


and


90


, and the blade


20


.




An additional feature, of this exemplary embodiment of a stripping tool


10


, in accordance with the present invention, is the interchangeability of the blade


20


. The blade


20


may be unfastened from the fastener


30


to replace the blade


20


in its entirety or to select which blade end


120


,


130


will perform the cutting. Alternately, the slider


40


and blade


20


can be simultaneously removed by adjusting the adjuster


70


until the slider


40


can be removed from the slider support


50


. Thus, both the blade


20


and the slider


40


can be simultaneously replaced, or the slider


40


and blade


20


, while integrated, may be flipped over to select which blade end


120


,


130


will perform the stripping.
