Definitions
- the invention relates to a composite profile with an extruded from light metal rail-like support body and its head surface spanning profile band of a harder metal.
- the invention covers a method for producing such a composite profile.
- DE 24 32 541 A1 discloses a method for producing busbars from a carrier profile and at least one support made of profile strip of another metal as a cover profile of high abrasion resistance, forming at least part of the surface of the carrier profile serving as the current conductor.
- the carrier profile is produced by pressing a block through the forming cross-section of a press die, and at the same time the profile strip passes parallel to the die longitudinal axis through the die opening or forming cross section.
- an intimate metallic connection is created between the two profile components. For example, when using the busbar for the electrification of rail-bound vehicles takes place in cases of particularly high load despite the intimate metallic connection long-term detachment of the profile strip from its support profile made of light metal.
- DE 44 10 688 Al is composite profile with a carrier profile made of light metal and an associated profile tape can be seen.
- the latter spans the surface of a rail head of the carrier profile, is cross-sectionally shaped like a groove and has in its side legs - from its supporting body side inner surface at a distance from each other projecting - formations, which are embedded in the support body.
- These shapes limit cut interspaces, which are positively filled by the metallic material of the support body. This positive connection is not afflicted with the defects described for metallic connection.
- the attachment of the coating on the serving as a carrier conductive rod is effected by the edges of the coating are clamped or pinched in the conductive rod. It creates at least a longitudinal depression in the lining, which penetrates into the conductive rod.
- a groove is provided in the conductive rod which divides a lip. The latter leads to jamming of the pad on the conductive rod, as soon as it has been at least partially folded and pressed against the edge of the pad.
- Busbars have proven to be disadvantageous, the wear component to be fastened by laterally passing through screws or additional plug-in organs on the current-carrying carrier profile.
- Other known Heinrichsver- methods can disadvantageously lead to ripples on the surface of the cover profile, which have their cause in the stepwise caulking or punching of the carrier profile.
- the insertion rod or the insertion profile is preferably made of the material of the profile strip, complements the profile strip on both sides and forms thanks to a welded connection secure protection for the inner surface of the current-carrying carrier profile.
- a gutter-like insertion rod of approximately V-shaped cross-section which is approximately axially parallel with a channel leg of the inner side of the side limb of the profile band, is preferred. IeI is present; the other channel leg is then directed to the longitudinal axis of the profile strip out and superimposed in an inclined to the cross-sectional longitudinal axis of the carrier profile at an angle slot.
- the cross section of the slot in the rail head of the carrier profile in turn should be V-shaped, wherein the running in the side or longitudinal surface of the rail head slot leg is formed by a L Lucasseinformung. That angle preferably measures 60 ° to 70 °, in particular 65 °.
- Another inventive insertion rod is of angular cross-section, which rests with a gutter leg of the inside of the side leg; the other gutter leg is away from the base plate of the profile band - or alternatively: inclined towards it.
- the limited by the two trough legs angle more than 90 ° measure, preferably about 110 °.
- a push rod with approximately semicircular cross section which is welded at the zenith of its curvature with the outer surface to the edge of the end face of the side limb of the profile band so that the two insertion rods of the profile band are arranged open in a common center axis and each other.
- This central axis crosses the cross-sectional axis of the composite profile, which in turn is parallel to its side surfaces.
- the center axis of the insertion rods in each of the two longitudinal surfaces of the rail head to determine the position of a bead whose cross-section is adapted to the shape of the interior of the insertion rod to be attached to him and on both sides of each slot for the free edge of the center axis inclined free end of the insert rod is limited.
- the cross-section of another embodiment according to the invention of the insertion profile or bar for the rail head consists of a quadrant section and a linear section, the latter of which is the side leg of the profile rail. bandes inside abuts and is welded to the end face.
- These quarter circle sections of the two insertion rods can be directed towards the base plate of the profile strip or away from it.
- the slot of the rail head for the linear portion of the insertion rod should contain here a longitudinal indentation in the longitudinal surface of the rail head. Moreover, it should be ensured that the pairings of uniform insertion rods offer a mirror image of the same design.
- a cross-sectional hook-like insertion rod with - running at a distance to the side legs - directed towards the base plate of the profile band free hook portion is welded to the other end of the side face of the side leg.
- Another embodiment covers a cross-sectionally step-like insertion rod, which is welded at one end to the inner surface of the profile band side leg and the other end engages behind a pin strip in the longitudinal surface of the rail head with its free hook end.
- a cross-sectionally step-like insertion rod which is welded at one end to the inner surface of the profile band side leg and the other end engages behind a pin strip in the longitudinal surface of the rail head with its free hook end.
- strip-like insertion rods which are created on the inside of the side legs of the profile band and project beyond their respective end face, with which they are connected by means of a continuous weld.
- This insert rod according to the invention to the cross-sectional longitudinal axis of the composite profile at an angle of about 60 ° to 80 ° - preferably 70 ° to 75 ° - inclined.
- one of the two opposing surfaces of the carrier profile and cover profile to the partner is curved cross-sectional, resulting in the required bias.
- the invention also covers a method for producing a composite profile, in which a carrier profile with a top surface and this on both sides accompanying plug-in slots is extruded from light metal material, also introduced in each slot slot a push rod and a protruding from the slot portion of the insertion rod a the top surface cross-profile band is designed so that the cover profile relative to the carrier profile has a bias.
- the insert rod is welded continuously to the profile strip.
- the anchoring strips, anchor rods or insertion rods are inserted or pressed or rolled into the light metal profile, in particular in an AL base profile, or are also rolled or firmly pressed before welding or subsequently by permanent deformation of the carrier profile. It is important to ensure that the bias is established between the partners.
- the stainless steel cover profile is then to be pressed onto the light metal support profile with the aid of a large diameter pressure roller and under this prestress at the same time to weld the anchoring strips or insertion rods with the cover profile right and left.
- the so-called cover profile is preferably a stainless steel strip cut from a rolling coil, which is brought into the desired shape by roll forming or used directly as a cut strip.
- the insert rod is a stainless steel strip - preferably the same alloy as the cover profile - which has advantageously been cut from the rolling coil and brought into the desired shape by roll forming / folding / tiling / re-forming.
