Abstract
The utility model discloses an aluminum profile with a smooth transition type groove. The aluminum profile with the smooth transition type groove can be used for manufacturing a contact rail in a metro power supply contact rail system. A smooth transition type structure is formed at the top of the aluminum profile with the smooth transition type groove, and consists of three parts, namely a flat bottom section positioned at the bottom of the groove and slope sections positioned on left and right sides, wherein the two ends of the flat bottom section are connected with the lower ends of the slope sections, and the upper parts of the slope sections are connected with the top of the aluminum profile, so that the smooth transition type groove is formed. Due to the adoption of the structure, die making is facilitated; two J profiles can be completely welded, so that strength is ensured; a gap between the aluminum profile with the smooth transition type groove and the J profile can be filled with a welding bead, so that current transmission is ensured.
Description
Affiliated technical field
The utility model relates to the mild transition type groove aluminium section bar using in a kind of subway power supply contact rail system, especially by by the aluminium section bar that welds the contact rail that obtains in the middle of two J section bars and use.
Background technology
Steel-aluminum conductor rail claims again conductor rail, the 3rd rail, is widely used a kind of main power supply part in electric power supply system for subway.Steel-aluminum conductor rail is to be formed by specific method manufacture by stainless steel band and aluminium section bar.Stainless steel band has the features such as the hardness, resistance to abrasion of requirement, as wear-resisting part, contacts with collector shoe.Aluminium section bar conducts electricity very well, and its Main Function is transmission current.When electric current is transferred to stainless steel band from aluminium section bar, between aluminium section bar and stainless steel band, the tightness degree of combination is just directly connected to resistance sizes and then has influence on current delivery.Stainless steel band is combined closelyr with aluminium section bar, and interface resistance is just less, and what electric current just can be better is transferred to stainless steel band and then is transferred on subway train.Otherwise stainless steel band and aluminium section bar can not be combined closely, interface resistance increases, and electric current is that loss is large be transferred to stainless steel band from aluminium section bar, and power consumption is just large.At present, steel-aluminum conductor rail is mainly by two kinds of forms of the composition, a kind of Wei“ aluminium Baogang " structure, another kind is " ladle aluminium " structure.The contact rail of aluminium armored structure is to consist of aluminium section bar head parcel stainless steel band side, stainless steel band side gos deep into aluminium section bar, aluminium section bar side has impact dent, pit bottom have part aluminium section bar embed corrosion-resistant steel with holes in, stainless steel band and aluminium section bar fixation principle are for to couple together stainless steel band and aluminium section bar with pin.The contact rail of ladle constructed of aluminium is with stainless steel band, to wrap aluminium section bar to form, and two stainless steel bands are " J " type, are called J section bar, and J section bar hook dress part catches on aluminium section bar, and the place, gap then forming at two J section bars is welded." ladle aluminium " formula contact rail is due to place, the gap welding that need to form at two J section bars, and welding region need to weld completely, has not allowed standoff effects current delivery.Aluminium section bar top channel form directly affects welding quality and electric current conduction.Without the improved aluminium section bar top channel groove structure that takes the shape of the letter U, when two J section bars are welded in centre, wlding can not weld two J section bars completely, and can form space at aluminium section bar top channel sharp corner, affects weld strength and then has influence on electric current conduction.And U-lag structure aluminum section bar is unfavorable for mould molding processing.
Summary of the invention
In order to overcome the deficiency of " ladle aluminium " formula contact rail U-shaped groove-type aluminum section used, the utility model provides a kind of mild transition type groove aluminium section bar, this aluminium section bar top channel is mild transition type structure, not only be beneficial to Extrusion Process of Aluminum Alloy Profile moulding, and can guarantee two J section bar welding completely, thereby weld strength and current delivery have been guaranteed.
The utility model solves the technical scheme that its technical matters adopts: mild transition type groove aluminium section bar, at aluminium section bar top, form a mild transition type structure, this structure is comprised of three parts, be positioned at flat section of channel bottom, be positioned at the slope section of the right and left, the two ends of flat section are connected with the lower end of slope section, and the top of slope section is connected with aluminium section bar top, have so just formed a mild transition type groove.
The beneficial effects of the utility model are, aluminium section bar groove changes mild transition type structure into, and aluminium section die is easy to produce, and mold hot can not produce stress yet and concentrates and cause cracking while processing.During welding, J section bar can weld completely, and welding space produces, and has guaranteed weld strength and current delivery.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the mild transition type groove of the utility model aluminium section bar.
Fig. 2 is the mild transition type groove of the utility model aluminium section bar U-shaped groove and mild transition type groove comparison diagram.
Fig. 3 is the novel mild transition type groove aluminium section bar fit on J section bar schematic diagram of this use.
Fig. 4 is schematic diagram after the upper J section bar of the novel mild transition type groove aluminium section bar welding of this use.
1 aluminium section bar in figure, 2.J section bar, 3.U shape plough groove type welding bead, 4. mild transition type welding bead.
The specific embodiment
In Fig. 1, mild transition type groove aluminium section bar, its top is mild transition type groove.
In embodiment illustrated in fig. 2, left figure is U-shaped groove, and right figure is mild transition type groove.
In the embodiment shown in fig. 3, two J section bars are placed on and prepare position of weld, aluminium section bar and J section bar close contact.Left figure, after two J section bars coordinate with aluminium section bar, forms U gender gap groove between aluminium section bar and J section bar.Left figure is after two J section bars coordinate with aluminium section bar, forms mild transition type groove between aluminium section bar and J section bar.
In the embodiment shown in fig. 4, left figure will form the welding bead shown in 3 after two J section bar welding, and as can be seen from the figure, welding bead is not full by the U-shaped trench fill between aluminium section bar and J section bar, at two side positions away from centre, has formed space.Right figure will form the welding bead shown in 4 after two J section bar welding, and as can be seen from the figure, welding bead can be full by the U-shaped trench fill between aluminium section bar and J section bar, at two side positions away from centre, do not form space.
Claims (2)
1. a mild transition type groove aluminium section bar, change aluminium section bar top channel form, it is characterized in that: at aluminium section bar top, form a mild transition type structure, this structure is comprised of three parts, be positioned at flat section of channel bottom, be positioned at the slope section of the right and left, the two ends of flat section are connected with the lower end of slope section, the top of slope section is connected with aluminium section bar top, has so just formed a mild transition type groove.
2. mild transition type groove aluminium section bar according to claim 1, is characterized in that: welding bead can fill up the space between aluminium section bar and J section bar.
