Abstract

The invention discloses a no-rerolling tube section production process. The process comprises the following steps: a, edge rolling: producing an edge rolling sample plate; when the length of the sample plate is 800mm and the thickness of the sample plate is 10-20mm, the pressure of the edge rolling sample plate is controlled within 20-40MPa; when the thickness of the sample plate is larger than 20mm, the pressure of the edge rolling sample plate is controlled within 40-60MPa; b, welding: firstly, welding inner seams, and then welding outer seams; during welding, according to the different thicknesses of steel plates, adopting welding wires with different diameters, and setting different welding currents, welding voltages and welding speeds for welding operation. The process is easy to operate, does not require a rerolling process, greatly improves the production efficiency, lowers the production cost, and is easy to master.

Description

A kind of without returning cylinder joint manufacture craft
Technical field
The present invention discloses a kind of manufacture craft of shell ring, particularly a kind of without returning cylinder joint manufacture craft.
Background technology
At present, wind Ta Tajie is in process, the general veneer reeling machine that first adopts carries out volume circle, then weld, in welding process, there will be the local deformation of tower joint, the phenomenon such as uneven, after welding, need to carry out again Hui Yuan, complex manufacturing technology, and making long in time limit, cost of manufacture is higher, inefficiency.
Summary of the invention
The object of the invention is to overcome above deficiency, providing a kind of simple to operate, easily controlling, reduce cost of manufacture, without the need to the shell ring manufacture craft of Hui Yuan.
Object of the present invention is achieved through the following technical solutions: a kind of without returning cylinder joint manufacture craft, comprises the following steps:
A, volume circle: make volume round template, when model length is 800mm, when sheet metal thickness is 10mm to 20mm, by roll bending Stress control at 20-40Mpa; When sheet metal thickness is greater than 20mm, roll bending pressure is arranged on 40-60Mpa, during stewing head, radian controls as shown in the table:
t(mm) 10 12 14 16 18 20 24 30
L(mm) 800 800 800 800 800 800 800 800
d(mm) 1.0 1.0 1.5 2.0 2.0 2.5 2.5 2.5
(t is sheet metal thickness, and L is panel length, and d is radian deviation)
B, welding: first weld inseam, then weld out-seam, according to the different-thickness of steel plate during welding, adopt the welding wire of different-diameter, and different welding currents, weldingvoltage, speed of welding are set, concrete technical parameter is as following table: when sheet metal thickness is 10mm to 20mm:
When sheet metal thickness is greater than 20mm:
。After longitudinal seam welding terminates, because the outer imperial palace of groove type is little, outer longitudinal joint heat input is larger than interior longitudinal joint, the amount of contraction in outer longitudinal joint region is larger than the amount of contraction in interior longitudinal joint region, d value deviation in upper table can be balanced, thus make radian within deviation range, no longer need back sired results sequence.
The present invention utilizes reversible deformation to control, longitudinal seam joint is allowed to have inside trend, according to said welding method, first weld inseam, rear weldering out-seam, the welding current that welding process specifies in strict accordance with welding procedure, voltage, speed of welding are to carry out welding operation, do not need back sired results skill, greatly improve production efficiency, and reduce production cost, simple to operate, easily control.
detailed description of the invention:
in order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
A kind of nothing of the present invention returns the detailed description of the invention of cylinder joint manufacture craft, comprises the following steps: a, volume circle: make volume round template, when model length is 800mm, when sheet metal thickness is 10mm to 20mm, by roll bending Stress control at 20-40Mpa; When sheet metal thickness is greater than 20mm, roll bending pressure is arranged on 40-60Mpa, during stewing head, radian controls as shown in the table:
t(mm) 10 12 14 16 18 20 24 30
L(mm) 800 800 800 800 800 800 800 800
d(mm) 1.0 1.0 1.5 2.0 2.0 2.5 2.5 2.5
(t is sheet metal thickness, and L is panel length, and d is radian deviation)
B, welding: first weld inseam, then out-seam is welded, according to the different-thickness of steel plate during welding, adopt the welding wire of different-diameter, and different welding currents, weldingvoltage, speed of welding are set, concrete technical parameter is as following table: when sheet metal thickness is 10mm to 20mm, and process technology parameter is as following table:
When sheet metal thickness is greater than 20mm, process technology parameter is as following table:
; After longitudinal seam welding terminates, because the outer imperial palace of groove type is little, outer longitudinal joint heat input is larger than interior longitudinal joint, the amount of contraction in outer longitudinal joint region is larger than the amount of contraction in interior longitudinal joint region, d value deviation in upper table can be balanced, thus make radian within deviation range, no longer need back sired results sequence.
The present invention utilizes reversible deformation to control, longitudinal seam joint is allowed to have inside trend, according to said welding method, first weld inseam, rear weldering out-seam, the welding current that welding process specifies in strict accordance with welding procedure, voltage, speed of welding are to carry out welding operation, do not need back sired results skill, greatly improve production efficiency, and reduce production cost, simple to operate, easily control.
