Definitions

the invention relates to a protective element for covering partial areas of a workpiece to be machined, consisting of a plastically deformable material, for example graphite, which is resistant to temperatures of up to 1000 ° C.
a protective element which consists of a material which is temperature-resistant and plastically deformable at least up to 1000 ° C.
Graphite is preferably suitable as the protective material.
Such an element is described in DE-OS 33 15 894.
it has proven difficult to press a threaded element into a long or long element in relation to its diameter.
significantly more graphite is consumed than would be necessary due to the thread dimensions alone.
a certain limit for the ratio of element height to element diameter (H / D) must be observed. This in turn means the production of protective elements of different wall thicknesses for threads of different lengths.
the invention is based on the object to remedy this and to form a protective element according to the generic term so that even with a large ratio of thread length to diameter, pressing is possible without a high cost of materials.
the solution according to the invention is characterized in that the deformable material is provided with a metal reinforcement.
This can be tubular or ring-shaped, wherein the deformable protective material can be arranged in the region of the ends of the metal reinforcement in the form of outer or inner rings.
the deformable protective material enclose the metal reinforcement in the form of a jacket as an outer or inner film.
Steel is particularly well suited as a material for the metal reinforcement, which in particular permits the processing of the protective elements in an automatic machine or enables the automatic pressing of the protective elements in the first place.
the arrangement of the protective material, for example graphite in the form of rings, material is saved considerably without fear of the penetration of liquid material such as zinc and the like into a thread to be protected.
the formation of a protective element in the form of a tubular steel core with an outer or inner film made of protective material has also been found to be effective.
the tubular protective element is simply pressed into a threaded bore or pushed over an external thread, and a part of the protective element can protrude outward beyond the threaded end. Installation is both extremely simple and suitable for different thread depths and inexpensive to manufacture thanks to the small amount of protective material.
Rings 2 and 3 made of graphite are attached to the outer circumference of a tubular reinforcement 1 (FIG. 1).
the tube 1 with its ring elements 2, 3 is pressed into the threaded bore 4 of a workpiece 5, as shown in FIG. 2.
FIG. 4 Another embodiment of a protective element is shown in FIG. This element can also be pressed into a threaded bore 7 of a workpiece 8, similar to FIG. 2. 4 is a blind hole into which the element with the film 6 is pressed until the inner end of the blind hole is reached. The upper end of the protective element can protrude from the workpiece.
a workpiece 9 provided with a peg-shaped external thread is enclosed by a protective element, the tubular reinforcement 1 of which is equipped with rings made of graphite.
the rings 2, 3 are arranged on the inner circumference of the reinforcement and again in the region of the ends.
the protective element according to FIG. 6 can be processed in the same way with a tubular reinforcement 1 and an inner film 6.
