Abstract
The object of the present invention is to provide a kind of edge rolling method of cylinder, it is possible to increase drilling precision and efficient, comprises the following steps：A) plate of suitable dimension is chosen according to the diameter of required cylinder, length and intensity requirement；B) plate is sent into lathe and by three-dimensional simulation bore size, synchronization perforate during to sheet shearing, obtains model；C) pre-bending is carried out to the model obtained after step b) with die for fisrt forming, cuts off redundance plate after pre-bending；D) model obtained after step c) processes it longitudinal seam welding groove；E) model obtained after step d) is sent into furling plate round machine and carries out edge rolling；F) to being welded at longitudinal joint.In such scheme, synchronization perforate while to sheet shearing, by three-dimensional simulation bore size, precision is high, controllability is high, treats that edge rolling, operative employee can directly enter welding tube socket process, improve work efficiency again after perforate.
Description
Technical field
The present invention relates to cylinder processing technique field, and in particular to a kind of edge rolling method of cylinder.
Background technology
Cylinder is applied to every field, particularly in the boiler manfacturing in power plant be even more be seen everywhere, due to need from
Various heating pipelines, outlet pipe etc. are drawn on the cylinder of boiler etc., therefore will be in the periphery wall in cylinder when processing cylinder
Upper perforate.In the prior art, typically first by after the circular cylinder body of model Juancheng, rule as needed, draw a design, dotting punch and obtain
To satisfactory hole, but need manually to calculate the suitable position of perforate, it is time-consuming and laborious, while be also easy to malfunction, cause to imitate
Rate is low and the waste of material.
The content of the invention
The object of the present invention is to provide a kind of edge rolling method of cylinder, it is possible to increase drilling precision and efficient.
To achieve these goals, the technical solution adopted by the present invention is：A kind of edge rolling method of cylinder, including following step
Suddenly：
A) plate of suitable dimension is chosen according to the diameter of required cylinder, length and intensity requirement；
B) plate is sent into lathe and by three-dimensional simulation bore size, synchronization perforate during to sheet shearing, obtains model；
C) pre-bending is carried out to the model obtained after step b) with die for fisrt forming, cuts off redundance plate after pre-bending；
D) model obtained after step c) processes it longitudinal seam welding groove；
E) model obtained after step d) is sent into furling plate round machine and carries out edge rolling；
F) to being welded at longitudinal joint.
In such scheme, synchronization perforate while to sheet shearing, by three-dimensional simulation bore size, precision is high, can
Control property is high, treats that edge rolling, operative employee can directly enter welding tube socket process, improve work efficiency again after perforate.
Embodiment
A kind of edge rolling method of cylinder, comprises the following steps：
A) plate of suitable dimension is chosen according to the diameter of required cylinder, length and intensity requirement；
B) plate is sent into lathe and by three-dimensional simulation bore size, synchronization perforate during to sheet shearing, obtains model；
C) pre-bending is carried out to the model obtained after step b) with die for fisrt forming, cuts off redundance plate after pre-bending；
D) model obtained after step c) processes it longitudinal seam welding groove；
E) model obtained after step d) is sent into furling plate round machine and carries out edge rolling；
F) to being welded at longitudinal joint.
In such scheme, synchronization perforate while to sheet shearing, by three-dimensional simulation bore size, precision is high, can
Control property is high, treats that edge rolling, operative employee can directly enter welding tube socket process, improve work efficiency again after perforate.Wherein pre-bending
And processing longitudinal seam welding groove is to ensure to weld the overall circularity of rear cylinder body.
Further, the model length that is obtained after step b), width are respectively slightly larger than the length after the expansion of required cylinder, width
Degree.This is to be used to process welding groove to leave certain surplus, to prevent from influencing the barrel dliameter of shaping rear cylinder body.
Further, plate is cut and is punched using flame cutting machine in step b).Gas flame cuttiug precision is high, must
The defects of should also polishing before welding groove when wanting, ensureing groove face flawless, layering, slag inclusion, improve entire body
Welding quality.
