Double-head welding and milling machine for steel aluminum composite rails

Abstract

The invention relates to a double-head welding and milling machine for steel aluminum composite rails, and belongs to special processing equipment for steel aluminum composite conductor rails of third rail ladle aluminum of an urban rail transit power supply system. The double-head welding and milling machine for the steel aluminum composite rails mainly comprises a base 1 with a rolling guide rail pair 18, a sliding plate 2 provided with a double-head welder 3 and a double-head milling machine 15 and a clamping device 32 with a cylinder 16, the sliding plate 2 moves by the aid of a power device 33 composed of a speeding regulating motor 4, a reduction gearbox 7 and the like. Two J-shaped or L-shaped stainless steel bars 31 are transversely fastened on the upper portion of each of two H-shaped aluminum sections 30 with the length of 15m or 18m, then the stainless steel bars 31 and the H-shaped aluminum sections 30 are transversely clamped by the clamping device 32, the sliding plate 2 is started to horizontally move from end to end, and the double-head welder 3 on the sliding plate 2 starts automatic MiG gas shielded welding to enable each J-shaped or L-shaped stainless steel bar to form a C-shaped whole. Two milling cutters 24 on the double-head milling machine 15 in the rear of the sliding plate 2 rotate coordinately to flatly mill weld joints 34 on the stainless steel bars so as to composite the stainless steel bars 31 and the aluminum sections 30, and accordingly steel aluminum composite conductor rails of ladle aluminum 19 are formed. The two working procedures of welding and milling are combined to be completed on the same complete machine, two steel aluminum composite rails can be welded and milled simultaneously, production efficiency is high, and steel and aluminum composite quality is good.

Description

technical field [0001] The invention relates to a steel-aluminum composite rail double-head welding and milling machine, which belongs to the production equipment of equipment used for power supply of urban rail transit. Background technique [0002] Before the present invention is made, in the prior art, the third rail power supply of urban rail transit adopts 2 J-shaped or L-shaped steel horizontal buckles on the I-shaped aluminum profile through welding and milling flat welding seam to become a steel-aluminum composite conductive rail. For example, the deicing steel-aluminum composite conductor rail with patent No. ZL201020004148.X, and the three-way high-strength steel-aluminum composite conductor rail with patent No. ZL201020281928.9. It can only process 0.1 meters per minute. After welding, it can only mill flat weld seams on an extended special milling machine. It can only mill 0.1 meters per minute. A 15-meter-long steel-aluminum composite rail needs to be processed ...

[0002] Before the present invention is made, in the prior art, the third rail power supply of urban rail transit adopts 2 J-shaped or L-shaped steel horizontal buckles on the I-shaped aluminum profile through welding and milling flat welding seam to become a steel-aluminum composite conductive rail. For example, the deicing steel-aluminum composite conductor rail with patent No. ZL201020004148.X, and the three-way high-strength steel-aluminum composite conductor rail with patent No. ZL201020281928.9. It can only process 0.1 meters per minute. After welding, it can only mill flat weld seams on an extended special milling machine. It can only mill 0.1 meters per minute. A 15-meter-long steel-aluminum composite rail needs to be processed for at least 300 minutes. The production speed is too high. slow and less efficient
