Abstract
The invention provides a method for trimming a large-diameter barrel and relates to the field of barrel trimming. The method is particularly suitable for a barrel of over phi 6000 mm, and the shortcoming of using vertical lathe processing to perform large-diameter barrel trimming in the prior art is overcome. A semi-automatic gas cutting device is utilized to perform processing. The method comprises the following steps: lifting a to-be-processed barrel to a rolling wheel tire frame 4 and causing the to-be-processed barrel to be in a horizontal state; fixedly installing the semi-automatic gas cutting device on the ground and causing the semi-automatic gas cutting device to be at the position which is at an appropriate distance from the to-be-processed barrel; according to the cutting dimension and angle requirements of the to-be-processed barrel, and adjusting the angle of a cutting machine burner port 3; turning on a switch of a rolling wheel tire 4, rotating the barrel, and maintaining the cutting machine burner port 3 at a required angle; and after the barrel rotates to keep a constant speed, turning on a cutting machine switch to perform gas cutting processing. The method is simple, the production cycle is shortened, the productivity is improved, the manufacturing cost is reduced, and the on-site processing difficulty is improved greatly.
Description
Technical field
The present invention relates to the cylindrical shell chamfered edge manufacture field of the equipment of transfiniting, be especially suitable for φ 6000mm with upper shell.
Background technology
In mechanical chemical industry industry, for the chamfered edge of cylindrical shell, prior art adopts vertical Vehicle Processing.Due to the restriction of being transported, for the equipment barrel that transfinites, single-unit cylindrical shell divides many lobes to deliver by we usually, and it is shaping to carry out distinguish assembly welding longitudinal joint at the scene, carries out chamfered edge processing again, then complete follow-up circumferential weld group pair after shaping to cylindrical shell.Use vertical Vehicle Processing cylindrical shell chamfered edge, there is following shortcoming:
1, for the cylindrical shell of the equipment of transfiniting, need that vertical vehicle device is installed in equipment erecting bed and process needing the cylindrical shell of chamfered edge, vertical car is installed costly.
2, because the ovality of large-diameter cylinder body is difficult to control, barrel distortion is comparatively serious, causes certain difficulty to the accuracy of vertical Vehicle Processing.
3, the workload of chamfered edge processing is comparatively large, increases cylindrical shell processing charges.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the defect of prior art with vertical Vehicle Processing cylindrical shell chamfered edge.
The invention provides a kind of method of the large-diameter cylinder body chamfered edge that transfinites, utilize semi-automatic gas cutting equipment to process, comprise the following steps:
(i) cylindrical shell to be processed is winched on roller moulding bed 4, and sentence horizontally-arranged state;
(ii) by semi-automatic gas cutting equipment fixed installation on the ground, apart from cylindrical shell suitable location to be processed;
(iii) by barrel cutting size to be processed and angle requirement, the angle of adjustment cutting machine nozzles 3;
(iv) open roller tire 4 switch, cylindrical shell rotates, and makes cutting machine nozzles 3 keep the angle required;
(v) after barrel body rotation remains a constant speed, open cutting machine switch, carry out gas cutting processing;
(vi), after gas cutting completes, remove and saute slag;
(vii) nondestructive inspection is carried out to cutting part, after qualified, go to lower sequence;
(viii) site clearing.
The present invention compared with prior art has the following advantages:
1, the present invention uses in gas cutting machine chamfered edge process, can by the angle of adjustment gas cutting machine machine mouth, avoids cylindrical shell ovality to exceed standard the impact caused to chamfered edge;
2, the inventive method is simple, not only effectively shortens the production cycle, improves operating efficiency, has saved manufacturing cost.
3, the use of portable processing method, significantly improves the difficulty of making in site processing, for work on the spot provides reference.

In figure: the cutter of 1 vertical car, 2 cylindrical shells.
Fig. 2 semi-automatic gas cutting machine gas cutting cylindrical shell chamfered edge schematic diagram,
In figure: the machine nozzles of 3 semi-automatic gas cutting machines, 4 roller tires.
Detailed description of the invention
By reference to the accompanying drawings 2, concrete grammar of the present invention is described as follows:
1, cylindrical shell to be processed is winched on roller tire 4 frame, and sentence horizontally-arranged state;
2, by semi-automatic gas cutting equipment fixed installation on the ground, apart from cylindrical shell suitable location to be processed;
3, by cutting size and the angle of cylindrical shell requirement to be processed, adjustment cutting machine nozzles 3 angle;
4, open roller tire 4 switch, cylindrical shell rotates, and makes cutting machine nozzles 3 keep the angle required;
5, after barrel body rotation remains a constant speed, open cutting machine switch, carry out gas cutting processing;
6, after gas cutting completes, remove and saute slag;
7, nondestructive inspection is carried out to cutting part, after qualified, go to lower sequence;
8, site clearing.
The present invention is applied to the cylindrical shell chamfered edge processing of the equipment of transfiniting, and particularly φ 6000mm is with upper shell.
Effect is especially obvious.
