Description

The flexible formation machine

Technical field

The utility model flexible formation machine belongs to straight-line joint submerged arc welding tube former technical field.

Background technology

What existing straight-line joint submerged arc welding tube moulding was adopted is to mainly contain the UOE production technology: the UOE production technology is to adopt large pressing machine (pressure 16; More than 000 ton) steel plate that will cut into certain size in advance through mould is pressed into the U type; Use second large pressing machine (pressure 20 again; More than 000 ton) through mould the pipe embryo of U type is pressed into the O type, then with submerged arc welding machine with steel pipe spot welding, and then carry out interior weldering, outside weld and finally form steel pipe.

This production technology exists equipment huge, and energy consumption is very high, invests huge shortcoming.Thereby cause the cost of steel pipe high, price is high, and market sale is restricted.

The JCOE production technology is to adopt medium-sized forcing press (pressure 6; About 000 ton) will cut into the limit portion pre-bending of the steel plate of certain size in advance through mould; Use medium-sized forcing press (pressure 8 again; About 000 ton) through mould steel plate is pressed into circle piecemeal, then with submerged arc welding machine with steel pipe spot welding, and then carry out interior weldering, outside weld and finally form steel pipe.

This production technology exists equipment huge, and energy consumption is high, and investment is big, inefficient shortcoming.Thereby cause the cost of steel pipe high, price is high, and market sale is restricted.During the steel pipe of special minor diameter on the make, price is very high especially, and the selling market is very influenced.

The utility model content

For overcoming the deficiency of prior art, the utility model provides a kind of equipment price low, and moulding is easy, and the steel pipe after the moulding is destroyed little flexible formation machine.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the flexible formation machine comprises thick forming frame and precisive shaped frame; Thick moulding comprises 1～2 plain-barreled roll frame; 3～5 four-roll racks, 3～5 C type standing roller frames, the precisive shaped frame comprises 2～4 four-roll racks.

Thick moulding comprises the first plain-barreled roll frame, first four-roll rack, second four-roll rack, the 3rd four-roll rack, the 4th four-roll rack, a C type standing roller frame by the order that coil of strip gets into; The 2nd C type standing roller frame, the 3rd C type standing roller frame and the 4th C type standing roller frame, the precisive shaped frame comprises the May 4th roller frame and the 6th four-roll rack by the order that coil of strip gets into.

The first plain-barreled roll frame, first four-roll rack, second four-roll rack, the 3rd four-roll rack, the 4th four-roll rack, a C type standing roller frame all are equipped with adjustment roll location motor and sensor on the 2nd C type standing roller frame, the 3rd C type standing roller frame, the 4th C type standing roller frame, the May 4th roller frame and the 6th four-roll rack.

The utility model is compared the beneficial effect that has with prior art:

1, the utility model steel plate becomes in the process of steel pipe, and most distortion is to lean on center fixation, and the mode of two springs extruding makes the radian that steel plate reaches to be needed, rather than lean on the arc of top and bottom rolls rigid steel plate is pressed into radian.Flexible formation can be avoided the surface of steel plate scratch, reduces residualinternal stress, reduces roll quantity, reduces roll change.

No longer with hanging out roll mandrel, but,, roll is adjusted to position accurately when 2, the utility model is changed specification, and need not split out roll adjustment through motor and sensor according to precalculated database.
