Detailed description of the invention
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.
Embodiment 1:
As shown in Figure 1, a kind of down-hole 10m3 mine tram wheel, to position limitation protection method, by being welded on by steel plate 1 bottom mine car, girder 3 realizing, comprising the steps:
(1) by measuring mine tram wheel to the width of the width determination steel plate 1 of girder 3 bottom 2 wheel rims to mine car; The girder 3 getting 2m bottom mine car is benchmark, through measuring, takes turns to 2 wheel rims to girder 3 width 150mm, and in order to ensure that wheel is to 3 controlled spacing, steel plate 1 width control system that the present invention adopts is at 120mm;
(2) steel plate 1 is opened a double V-groove;
(3) harmful substance at the double V-groove place of sanding machine worn mine car girder 3 weld and steel plate 1 is used;
(4) first welding rod is cured before welding, temperature is 300 ~ 350 DEG C, and at welding position vertical position welding pin, steel plate 1 described in step (2) being welded on front group of wheel takes turns in girder 3 flush position before 22 to 21 girder 3 flush position and rear group, the weld seam of welding adopts multilayer multiple tracks, and after every layer of welding, molten slag removal also grinds off harmful substance, until the groove of the full steel plate of weldering, control weld bead height 0 ~ 2mm; The ratio be melted in ground floor weld metal due to mother metal is up to about 30%, so during the welding of ground floor weld seam, adopts small area analysis, slow speed of welding, to reduce the fusion penetration of mother metal.
(5) weld seam of steel plate 1 is incubated 2 ~ 6 hours at 200 ~ 350 DEG C, then carries out temper, the temperature of tempering is 600 ~ 650 DEG C, then is incubated 1 ~ 2 hour.
The steel plate 1 of the present embodiment adopts 4 blocks of 16Mn steel plates, and its length is 240mm, and width is 120mm, and thickness is 20mm.
Wherein, the welding machine that the present embodiment adopts is ZX7-400, and welding rod is E5015.During welding, the angle of welding rod and welding direction is 90 degree time, and electric arc is concentrated, and bath temperature is high, angle is little, and electric arc disperses, and bath temperature is lower, as 20mm downhand welding back cover layer, welding rod angle: 50 ~ 70 °, makes bath temperature decline to some extent, avoids the back side and produces overlap or rise high.After 20mm plate vertical position welding back cover layer changes welding rod, adopt the welding rod angle of 90 ~ 95 °, bath temperature is improved rapidly during joint, molten hole can smooth opening, and back-welding shape is more smooth, effectively controls the phenomenon of tap points indent.
Meanwhile, control the electric current of welding during welding and select corresponding core diameter: select welding current and core diameter according to weld seam locus, welding level, when snapping, the welding current selected and core diameter are comparatively large, vertical, horizontal position of facing upward is less.Steel plate 1 thickness of the present embodiment is 20mm, and select the welding rod of φ 3.2mm during welding back cover layer, welding current is 80 ~ 85A, and fill, capping layer selects the welding rod of φ 4.0mm, and welding current is 165 ~ 175A.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
