Description
~1 9~1 5~
Composite Section of two Different Metals, in Particular for Use as a Conductor Rail, and 1 ruC~S~ for the Manufacture thereof.
The invention relates to a composite section having a load-bearing profiled Gomponent made 5 of light weight metal and, metallically bonded to it during extrusion, at least one profiled strip of another metal which exhibits high resistance to wear, said composite section being for use as a conductor rail having a contact surface defined by the profiled strip. Furthermore, the invention also relates to a process for m~nllfiAc~lring such composite sections out of two profiled co-nponel,ls.
The German patent document DE-B 24 32 541 describes a process for m~nnfActuring con-ductor rails from a load-bearing section and at least one surface layer in the form of a profil-ed strip of another metal that forms at least part of the surface of the load-bearing section.
During an extrusion step the load-bearing section is formed by pressing an ingot block l S through the shape-giving opening of a die; at the same time, the profiled strip passes through the central axis of the die parallel to the die opening. The object of that invention, viz., to achieve an aclequAte joint between the surface layer and the substrate by economic means -also when not employing pre-clad strips - is achieved by producing at least two composite sections ~imllltAneously and such that the regions of the load-bearing sections to be clad with 20 surface layers face each other and profiled pairs of strips lying on top of each other are passed between these regions through the openil-g in the shape-giving die.
Many section shapes have been produced using this process. Provided there is no adequAte interlocking of the alllminillm base section and the profiled strip, it is necessary to demon-25 strate that the joint is adeql-Ate- e.g. by shear tests involving both materials. In addition, the known processes lead in particular to sections in which the wear resictAnce is determined by a thin steel strip Iying parallel to the sliding contact surface. The thickness of the malleable steel strip and with that also the maximum depth of wear is, accordillg to the state of the art, at present at most 6 mm.
In view of this state of the art, the object of this invention is to improve the join between the load-bearing section and the profiled strip - also in the case of non-preclad profiled strips at the same time re~A;~ g the special economic aspects of mAnllfAct lre; this should lead to a reduction or e~ n~lion of current production and testing expenditures and an increase in 35 wear life i.e. the service life ~Apecled from the product.
case2095 That objective is achieved by way of the invention according to the main claims; the dependent, sub-claims refer to favourable versions thereof.
In accordance with the invention at least one profiled strip is embedded in the light metal 5 material apploxilllaLely perpçn~lic~ r to or inclined to the sliding contact plane which should prerel~bly be fitted, at least on its principle surface, with recesses, openings, rills, grooves or the like depressions in order to improve the interlocking action.
Two designs have proved to be favourable viz., in one case the arrangement of a profiled 10 strip in the longitudinal axis of the composite section such that a narrow side of this profiled strip defines the sliding contact plane, and in the other case a composite section with profiled strips arranged on both sides of and a ~ t~nce from the lon~hl~lin~l axis.
Within the scope of the invention, therefore, the profiled strips e.g. of copper or iron-based 15 materials, in particular steel, are brought into contact with the ~ minillm matrix on both broad faces and a small edge face, which leads to much greater joining surfaces and to a higher degree of friction between the two materials.
According to the invention the profiled strips are surrounded on all sides by light weight 20 metal, the narrow side repres~nting the sliding contact surface being covered by a thin layer of light weight metal; this prevents damage to the die wall in that it prevents immediate con-tact with the profiled strip or strips.
According to another feature of the invention a desk-like inclined surface runs at least at the 25 side of one of the narrow sides and l~plesellls the limit of a rail head of the light metal com-ponent accommodating the profiled strip.
Such composite sections are m~nllf~chlred from at least two profiled components by extrud-ing a light metal matrix through a die opening while feeding at least one of the above 30 mentioned strip-shaped profiled components in the extrusion direction and namely such that strip-shaped profiled component is introduced, parallel to or inclined to the longitudinal axis of the die opening, into the light metal matrix in which both broad faces and at least one narrow face of the strip-shaped profiled component are embedded, thereby joining the two components together under force and by interlocking them with each other.
case2095 When pairs of composite sections are extruded simnlt~neously with sliding contact surfaces facing each other - as in patent document DE-B-24 32 541 - according to the invention a hollow chamber is formed between two parallel strip-like components introduced into the light metal matrix; the contour of the said chamber being formed by the desk-like inclined 5 sides of the composite section and crossed by the sliding contact surface plane. These two composite sections may then be separated at the sliding contact plane by introducing a sepa~ g tool into the hollow chamber of the section.
The given objective is achieved without problem by the described measures. Furthermore, the 10 following advantages are obtained:
- simplification of the extrusion tool and an increase in extrusion rate;
- reduction in development costs for new sections by employing interlocking components and new section shapes;
- production of composites of small cross-section with previously un~tt~in~hle wear resi~t~nce;
çl;",;n~l;on of composite testing as a result ofthe interlocking action achiev-ed during extrusion due to grooves, recesses, openings in the other~vise flat strip profile;
- increase in extrusion rate without having to ensure a metallic bond is achiev- ed;
- increase in the thickness of the wear-resistant part of the section head to plerelably 15 to 25 mm - corresponding to the anchoring or depth of profil-ed strip in the ~IIlminillm base section.
Further adv~nt~ges~ features and details of the invention are revealed in the following description of IJler~llt;d exemplified embodiments and with the aid of the drawing which shows in Figs. 1, 3: Cross-sectionthroughcomposite sections;
Fig. 2: A perspective view through two composite sections that have been produced ~imlllt~neously, and tool for sepal~ling them;
5 Fig. 4: Cross-section through two other, simllltAneously m~nllf~ctured composite sections.
case20ss A composite section 10 which may be employed as a conductor rail features, as shown in figure 1, a rail body which has been made by extruding an ~ mini~lm alloy featuring a horizontal base 12 extended to a T-shape by a neck 14 which continues further in the form of a bulge-shaped collar 16 and head 18. Embedded in this, Iying in the longihl(lin~l axis A, is a S flat rect~n~ r strip section 20 which - for the purpose of interlocking with the matrix material of the head 18 - features openings, recesses, grooves 22 and the like profile features or corrugations, knurling or the like surface structuring.
The thickness b of the strip section 20 is preferably about 5 mm, its cross-sectional height h 10 or the width of its broad faces 24 is here 15 to 25 mm; this corresponds to the wear surface dimension for such types of rails. The head 18 features desk-shaped downward sloping faces 28 on both sides of the narrow face 20 whose surface plane E serves as a sliding contact surface for a power collector which is not shown here. Also, connecting fishplates 15 are bolted to the rail neck for the purpose of joining the rail to a another aligned rail section.
Figure 2 shows the ~imlllt~neous production of a pair of composite sections 30 through a common opening of an extrusion die which is not shown here. The sliding contact faces 26 of a pair of profiled strip sections 20 - running parallel to and a dis~ance n from the axis of symmetry or central axis A - in the head 18 of one composite section 30 lie against the sliding 20 contact faces 26 of aligned profiled strip sections 20 of the other composite section 30. The side faces 28 fl~nkin~ the strip section 20, described in connection with figure 1, form in figure 2 a temporary hollow cha~ er 32 at the central axis A.
A~er cooling the result~nt extruded length of section, both composite sections are separated 25 by means of the shear 34 of a - here only sketched - sepal~ g mandrel 36 which is intro-duced into the hollow challlber 32 of the extruded section. The separation may also be pelrolllled after introducing a drawing mal-dlel into the hollow cha-llber 32.
The composite section 30a in figure 3 is shown without its partner section, i.e. as a single 30 section, both of its sliding contact faces 26 being covered by a skin of matrix material in order to protect the die. The same applies to the composite sections 30b shown in figure 4 which are made without a hollow challlbel in the section, and feature a flat top layer 40 which covers the sliding contact faces of its strip-shaped sections 20.

Composite Section of two Different Metals, in Particular for Use as a Conductor Rail, and 1 ruC~S~ for the Manufacture thereof.
The invention relates to a composite section having a load-bearing profiled Gomponent made 5 of light weight metal and, metallically bonded to it during extrusion, at least one profiled strip of another metal which exhibits high resistance to wear, said composite section being for use as a conductor rail having a contact surface defined by the profiled strip. Furthermore, the invention also relates to a process for m~nllfiAc~lring such composite sections out of two profiled co-nponel,ls.
The German patent document DE-B 24 32 541 describes a process for m~nnfActuring con-ductor rails from a load-bearing section and at least one surface layer in the form of a profil-ed strip of another metal that forms at least part of the surface of the load-bearing section.
During an extrusion step the load-bearing section is formed by pressing an ingot block l S through the shape-giving opening of a die; at the same time, the profiled strip passes through the central axis of the die parallel to the die opening. The object of that invention, viz., to achieve an aclequAte joint between the surface layer and the substrate by economic means -also when not employing pre-clad strips - is achieved by producing at least two composite sections ~imllltAneously and such that the regions of the load-bearing sections to be clad with 20 surface layers face each other and profiled pairs of strips lying on top of each other are passed between these regions through the openil-g in the shape-giving die.
Many section shapes have been produced using this process. Provided there is no adequAte interlocking of the alllminillm base section and the profiled strip, it is necessary to demon-25 strate that the joint is adeql-Ate- e.g. by shear tests involving both materials. In addition, the known processes lead in particular to sections in which the wear resictAnce is determined by a thin steel strip Iying parallel to the sliding contact surface.

case2095 That objective is achieved by way of the invention according to the main claims; the dependent, sub-claims refer to favourable versions thereof.
In accordance with the invention at least one profiled strip is embedded in the light metal 5 material apploxilllaLely perpçn~lic~ r to or inclined to the sliding contact plane which should prerel~bly be fitted, at least on its principle surface, with recesses, openings, rills, grooves or the like depressions in order to improve the interlocking action.
Two designs have proved to be favourable viz., in one case the arrangement of a profiled 10 strip in the longitudinal axis of the composite section such that a narrow side of this profiled strip defines the sliding contact plane, and in the other case a composite section with profiled strips arranged on both sides of and a ~ t~nce from the lon~hl~lin~l axis.
Within the scope of the invention, therefore, the profiled strips e.g. of copper or iron-based 15 materials, in particular steel, are brought into contact with the ~ minillm matrix on both broad faces and a small edge face, which leads to much greater joining surfaces and to a higher degree of friction between the two materials.
According to the invention the profiled strips are surrounded on all sides by light weight 20 metal, the narrow side repres~nting the sliding contact surface being covered by a thin layer of light weight metal; this prevents damage to the die wall in that it prevents immediate con-tact with the profiled strip or strips.
According to another feature of the invention a desk-like inclined surface runs at least at the 25 side of one of the narrow sides and l~plesellls the limit of a rail head of the light metal com-ponent accommodating the profiled strip.
Such composite sections are m~nllf~chlred from at least two profiled components by extrud-ing a light metal matrix through a die opening while feeding at least one of the above 30 mentioned strip-shaped profiled components in the extrusion direction and namely such that strip-shaped profiled component is introduced, parallel to or inclined to the longitudinal axis of the die opening, into the light metal matrix in which both broad faces and at least one narrow face of the strip-shaped profiled component are embedded, thereby joining the two components together under force and by interlocking them with each other.
case2095 When pairs of composite sections are extruded simnlt~neously with sliding contact surfaces facing each other - as in patent document DE-B-24 32 541 - according to the invention a hollow chamber is formed between two parallel strip-like components introduced into the light metal matrix; the contour of the said chamber being formed by the desk-like inclined 5 sides of the composite section and crossed by the sliding contact surface plane. These two composite sections may then be separated at the sliding contact plane by introducing a sepa~ g tool into the hollow chamber of the section.
The given objective is achieved without problem by the described measures. Furthermore, the 10 following advantages are obtained:
- simplification of the extrusion tool and an increase in extrusion rate;
- reduction in development costs for new sections by employing interlocking components and new section shapes;
- production of composites of small cross-section with previously un~tt~in~hle wear resi~t~nce;
çl;",;n~l;on of composite testing as a result ofthe interlocking action achiev-ed during extrusion due to grooves, recesses, openings in the other~vise flat strip profile;
- increase in extrusion rate without having to ensure a metallic bond is achiev- ed;
- increase in the thickness of the wear-resistant part of the section head to plerelably 15 to 25 mm - corresponding to the anchoring or depth of profil-ed strip in the ~IIlminillm base section.
Further adv~nt~ges~ features and details of the invention are revealed in the following description of IJler~llt;d exemplified embodiments and with the aid of the drawing which shows in Figs. 1, 3: Cross-sectionthroughcomposite sections;
Fig. 2: A perspective view through two composite sections that have been produced ~imlllt~neously, and tool for sepal~ling them;
5 Fig. 4: Cross-section through two other, simllltAneously m~nllf~ctured composite sections.
case20ss A composite section 10 which may be employed as a conductor rail features, as shown in figure 1, a rail body which has been made by extruding an ~ mini~lm alloy featuring a horizontal base 12 extended to a T-shape by a neck 14 which continues further in the form of a bulge-shaped collar 16 and head 18. Embedded in this, Iying in the longihl(lin~l axis A, is a S flat rect~n~ r strip section 20 which - for the purpose of interlocking with the matrix material of the head 18 - features openings, recesses, grooves 22 and the like profile features or corrugations, knurling or the like surface structuring.
The thickness b of the strip section 20 is preferably about 5 mm, its cross-sectional height h 10 or the width of its broad faces 24 is here 15 to 25 mm; this corresponds to the wear surface dimension for such types of rails. The head 18 features desk-shaped downward sloping faces 28 on both sides of the narrow face 20 whose surface plane E serves as a sliding contact surface for a power collector which is not shown here. Also, connecting fishplates 15 are bolted to the rail neck for the purpose of joining the rail to a another aligned rail section.
Figure 2 shows the ~imlllt~neous production of a pair of composite sections 30 through a common opening of an extrusion die which is not shown here. The sliding contact faces 26 of a pair of profiled strip sections 20 - running parallel to and a dis~ance n from the axis of symmetry or central axis A - in the head 18 of one composite section 30 lie against the sliding 20 contact faces 26 of aligned profiled strip sections 20 of the other composite section 30. The side faces 28 fl~nkin~ the strip section 20, described in connection with figure 1, form in figure 2 a temporary hollow cha~ er 32 at the central axis A.
A~er cooling the result~nt extruded length of section, both composite sections are separated 25 by means of the shear 34 of a - here only sketched - sepal~ g mandrel 36 which is intro-duced into the hollow challlber 32 of the extruded section. The separation may also be pelrolllled after introducing a drawing mal-dlel into the hollow cha-llber 32.
The composite section 30a in figure 3 is shown without its partner section, i.e. as a single 30 section, both of its sliding contact faces 26 being covered by a skin of matrix material in order to protect the die. The same applies to the composite sections 30b shown in figure 4 which are made without a hollow challlbel in the section, and feature a flat top layer 40 which covers the sliding contact faces of its strip-shaped sections 20.
