Abstract
The invention discloses an aluminum compressed elbow which comprises two arc half-tubes, wherein each arc half-tube is manufactured by bending a fan-shaped aluminum plate, and the two arc half-tubes are welded into an arc aluminum elbow. Through the way, according to the invention, a fold line of a traditional mitre elbow can be changed into an arc line, therefore, the airflow resistance is reduced, welding seams are reduced, the procedures of welding and radiographic testing are saved, the labor and the consumption are reduced, and the appearance of the aluminum compressed elbow is beautiful.
Description
Technical field
The present invention relates to a kind of aluminium elbow, relate in particular to a kind of aluminum compacting elbow and processing technology thereof.
Background technique
Along with from making middle-size and small-size air separation plant to evolution transition of making large air separation plant, as the essential element aluminum elbow that air separation plant fractionation tower interior conduit is used, the also necessary requirement that adapts to large sized complete sets of equipment; Not only specification is big but also wide in variety, and the existing market is more universal in the aluminium elbow preparation method who has only little caliber, and the aluminium elbow of big caliber is traditional dried shrimp elbow; For the splicing of multistage straight tube is formed; The elbow weld seam of this mode is many, and gas-flow resistance subtracts greatly, and the operation of welding and radiographic inspection is many; Long processing time has increased cost.
Summary of the invention
The present invention seeks to provides a kind of aluminum compacting elbow and processing technology thereof for the deficiency that overcomes existing technology, can the broken line of traditional dried shrimp elbow be become circular arc line, and gas-flow resistance reduces; Reduced weld seam; Save the operation of welding and radiographic inspection, fallen worker's consumption reduction, beautiful shape.
Technical solution of the present invention is achieved in that
A kind of aluminum compacting elbow saidly comprises two arc semicanals that are bent into by fan-shaped aluminium sheet, and two arc semicanals are welded into arc aluminium elbow.
A kind of processing technology of aluminum compacting elbow, the processing technology step of said arc aluminium elbow is following:
A) the raw material aluminium sheet is sheared two fan-shaped aluminium sheets;
B) mould of two fan-shaped aluminium sheets being put into the press of arc semicanal is processed and two arc semicanals;
C) the arc semicanal after will suppressing is put into die cavity, is pressed in and uses the metal slitting saw milling plane on the Drilling machines bench, all mills the two ends of two arc semicanals flat;
D) with the synthetic welding of two arc semicanals, put into die cavity then, the both sides screw clenches the aluminium elbow, metal slitting saw milling end face, 90 ° of pattern upsets, milling other end;
E) unclamp screw, take out the aluminium elbow and be processed finished products spare.
Preferably, the press among the said step B is an oil hydraulic press.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of aluminum compacting elbow of the present invention and processing technology thereof; Be welded into arc aluminium elbow by two arc semicanals that are bent into by fan-shaped aluminium sheet, the broken line of traditional dried shrimp elbow is become circular arc line, gas-flow resistance reduces; Reduced weld seam; Save the operation of welding and radiographic inspection, fallen worker's consumption reduction, beautiful shape.
Embodiment
A kind of aluminum compacting elbow saidly comprises two arc semicanals that are bent into by fan-shaped aluminium sheet, and two arc semicanals are welded into arc aluminium elbow.
A kind of step of processing technology of aluminum compacting elbow is following:

B) mould of two fan-shaped aluminium sheets being put into the oil hydraulic press of arc semicanal is processed and two arc semicanals;
C) the arc semicanal after will suppressing is put into die cavity, is pressed in and uses the metal slitting saw milling plane on the Drilling machines bench, all mills the two ends of two arc semicanals flat;
D) with the synthetic welding of two arc semicanals, put into die cavity then, the both sides screw clenches the aluminium elbow, metal slitting saw milling end face, 90 ° of pattern upsets, milling other end;
E) unclamp screw, take out the aluminium elbow and be processed finished products spare.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of aluminum compacting elbow of the present invention and processing technology thereof; Be welded into arc aluminium elbow by two arc semicanals that are bent into by fan-shaped aluminium sheet, the broken line of traditional dried shrimp elbow is become circular arc line, gas-flow resistance reduces; Reduced weld seam; Save the operation of welding and radiographic inspection, fallen worker's consumption reduction, beautiful shape.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
