According to the utility model, the tractor drives a steel strip to move, so that the steel strip sequentially passes across the press mold, the pre-bent mold and the mold head, then is gradually rolled in a tube shape, and welded by the welding torch, external threads are turned by the tool, and welding and thread turning are performed on a same assembly line, so that the threaded steel pipe processing device is simple in structure, low in cost, and high in production efficiency.
Description
Technical field
The utility model relates to steel pipe's production apparatus field, relates to or rather a kind of threaded steel pipe processing unit (plant).
Background technology
Welding is a kind of method conventional in steel pipe's production, is that steel plate or steel band are welded after cans again.Curling very large on Pipe Welding Quality impact before welding, the welding quality of existing steel-pipe welding device in order to obtain, bar structure designs to obtain more complicated, correspondingly, cost is also very high, and this kind equipment ratio is more suitable for welding big steel pipe, and for the less steel pipe of bore, rather waste one's talent on a petty job with this kind equipment, waste resource.
Threaded steel pipe is thread cutting in the outside wall surface of steel pipe, and existing production equipment is all that welding and cutting thread are separately carried out separately, and this has not only reduced production efficiency, and needs larger workshop, more personnel, is unfavorable for cost-saving.
Summary of the invention
The purpose of this utility model is, a kind of simple in structure, threaded steel pipe processing unit (plant) that cost is low is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of threaded steel pipe processing unit (plant), comprise workbench and welding gun, it is characterized in that, on workbench, set gradually pressing mold along straight line, die for fisrt forming, die head, hauling machine and core motor, the middle part of die for fisrt forming is provided with the circular arc gap of perforation, die head has perforation, conical taper hole, at the bottom of the cone of taper hole near die for fisrt forming one side, the head of welding gun is at the vertex of a cone place of described taper hole, the hollow shaft of core motor is provided with lathe tool, lathe tool has the through hole coaxial with hollow shaft, the inwall of through hole is provided with screw-shaped blade.
The utility model drives steel band to move by hauling machine, and steel band through pressing mold, die for fisrt forming and die head, is rolled into tubulose successively gradually, welded by welding gun again, afterwards by lathe tool car external screw thread processed, welding and cutting thread are carried out on a streamline, simple in structure, cost is low, production efficiency is high.

Fig. 2 is the front view of die for fisrt forming;
Fig. 3 is the hollow pipe part-structure schematic diagram of core motor;
Fig. 4 is weldering case phantom.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Detailed description of the invention
Referring to Fig. 1, threaded steel pipe processing unit (plant) comprises workbench 1, on workbench 1, sets gradually pressing mold 2, die for fisrt forming 3, weldering case 4, hauling machine 6 and core motor 8 along straight line, and welding gun 5 is in a side of weldering case 4.Pressing mold 2 comprises that the inner side that separates up and down two block pressur plate 21, two block pressur plates 21 of placing is equipped with pad 22, and steel band passes between two pads 22, pad 22 is pressed on steel band, steel band is flattened, and the fouls such as the dust on steel band is wiped, for follow-up bending ready.Referring to Fig. 2, die for fisrt forming 3 is roughly tabular, and middle part is provided with the circular arc gap 31 of perforation.Steel disc passes after pressing mold 2 from gap 31, and gap 31 curves circular shape steel band.
Referring to Fig. 3, weldering is provided with die head 7 in case 4, die for fisrt forming 3, die head 7 and hauling machine 6 layout that is in line, and die for fisrt forming 3 and hauling machine 6 lay respectively at die head 7 both sides in a straight line.The middle part of die head 7 has taper hole 71 perforation, conical, and at the bottom of the cone of taper hole 71, in close die for fisrt forming 3 one sides, the vertex of a cone is in close hauling machine 6 one sides.The head of welding gun 5 stretches in weldering case 4, and at the vertex of a cone place of taper hole 71.Steel disc enters the taper hole 71 of die head 7 out from die for fisrt forming 3, taper hole 71 progressively bends to tubulose the steel band of circular shape, and welding gun 5 again the steel band seam welding of tubulose together.Be welded in case 4 and carry out, the spark producing in welding is blocked in weldering case 4, is conducive to working environment and personal safety.
Core motor 8 is in a side of hauling machine 6, and referring to Fig. 3, the hollow shaft 81 of core motor 8 is provided with lathe tool 9, and lathe tool 9 has the through hole coaxial with hollow shaft 81, and the inwall of through hole is provided with screw-shaped blade.The steel pipe of welding fabrication passes from the hollow shaft 81 of core motor 8 and the through hole of lathe tool 9, and hauling machine 6 drives steel pipe movement, and core motor 8 drives lathe tool 9 to rotate, at the outer wall of the steel pipe external screw thread processed of getting on the bus.
