Summary of the invention
It is not easy to wear that technical matters to be solved by this invention is to provide one, and long service life is convenient to the clad type steel-aluminium composite conducting rail of installing.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Clad type steel-aluminium composite conducting rail, comprise aluminum alloy rail body and the stainless steel band of " work " font, the both ends of stainless steel band are stepped, stainless steel band embeds the top of aluminum alloy rail body, and the upper surface flush on the top of the upper surface of intermediate portion and aluminum alloy rail body, the both sides of the pars intermedia of aluminum alloy rail body are equipped with V shape centralized positioning line, and the lower surface central authorities of the bottom of aluminum alloy rail body have trapezoidal groove.
The method of making above-mentioned clad type steel-aluminium composite conducting rail, comprises the following steps:
(1) get aluminium alloy round cast ingot, the massfraction of its each composition is controlled at: Si:0.38～0.52%, Fe:0.10～0.18%, Mg:0.52～0.65%, Cu:0.05%, Mn:0.03%, Cr:0.03%, Zn:0.05%, Ti:0.02%;
(2) get 1Cr17 corrosion-resistant steel, cold drawn become band and its both ends are stair-stepping stainless steel band, and oil removing, scrubbing;
(3) respectively aluminium alloy round cast ingot being heated to 470～490 DEG C, recipient is heated to 410～430 DEG C, stainless steel band and is heated to 480～500 DEG C, squeezing dies and is heated to 460～480 DEG C;
(4) will heat rear stainless steel band imports in squeezing dies through pay-off, aluminium alloy round cast ingot after heating is sent in recipient, the squeese pressure producing by extrusion axis and dummy block flows aluminium alloy round cast ingot plastic deformation, and between stainless steel band, form metallurgical binding face closely, and synchronously extrude, form composite conducting rail;
(5) composite conducting rail of extruding is through spray equipment rapid quenching, and after tension straingtening, sawing dress basket, sends into aging oven and carry out timeliness heat treatment, and the temperature of aging oven is controlled at 175～185 DEG C, and temperature retention time is controlled at 7～9 hours;
(6) come out of the stove, inspection.
Advantage of the present invention is: this conductor rail is not easy to wear, long service life, splice easy for installation, and contact surface tight between aluminum alloy rail body and stainless steel band, withstanding corrosion, has ensured long-term low-resistance stability.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein, 1, aluminum alloy rail body, 2, stainless steel band, 3, V shape centralized positioning line, 4, trapezoidal groove.
Detailed description of the invention:
As shown in Figure 1, clad type steel-aluminium composite conducting rail, comprise aluminum alloy rail body 1 and the stainless steel band 2 of " work " font, the both ends of stainless steel band 2 are stepped, stainless steel band 2 embeds the top of aluminum alloy rail body 1, and the upper surface flush on the top of the upper surface of intermediate portion and aluminum alloy rail body 1, forms coated, has effectively eliminated the tendency that comes off of stainless steel band 2; The both sides of the pars intermedia of aluminum alloy rail body 1 are equipped with V shape centralized positioning line 3, and the lower surface central authorities of the bottom of aluminum alloy rail body 1 have trapezoidal groove 4.
The method of making above-mentioned clad type steel-aluminium composite conducting rail, comprises the following steps:
