Abstract

The invention provides a boiler cylinder body pipe hole face mold and a manufacturing method thereof. According to the method, by means of a computer and relative programs, a three-dimensional diagram corresponding to a boiler cylinder body is built in the computer according to requirements for design of boiler cylinder body pipe holes, then the diagram is spread to form a two-dimensional diagram, lines are revised, reference lines of regions are determined according to pipe hole distribution regions, a vector diagram is formed through conversion, a carving program is formed through conversion, hole profile lines and the reference lines are carved on a face mold material, and the pipe hole face mold is manufactured. According to the boiler cylinder body pipe hole face mold manufactured in the method, the size is accurate, the efficiency is high, the cylinder body pipe holes do not need cut for a second time, the face mold can be repeatedly used, and the face mold is suitable for large-scale production.

Description

Boiler barrel pore face mold and preparation method thereof
Technical field
The present invention relates to face mold and preparation method thereof for a kind of processing pore, especially a kind of boiler barrel pore face mold and preparation method thereof, belongs to Industrial Boiler processing technique field.
Background technology
Boiler body connects many group water-fire pipes, as shown in Figure 1, with water-fire pipe be welded to connect front need be on boiler barrel advanced promoting the circulation of qi cut through the hole of pipe, these holes include non-radially pore.All pores see it is all that concordant arrangement pitches is uniform by circular drum direction, after but circular drum launches, the ordered state of its pore will change, horizontal direction and vertical direction spacing all widen to both sides gradually from centre, every segment distance is all different, and middle hole sub-circular, hole has laterally become egg shape gradually, and it is large that the angle that each egg shape transverse line and horizontal line form outwards becomes gradually, causes line to make comparatively difficulty.At present the non-radially pore of drum ruler measurement router process flow is: on boiler barrel, determine subregion cross hairs, cylindrical shell altitude datum line, steel pipe hole site center line, center-punching, the line of apsides is justified with planing, the setting-out of pore outline line.
On cylindrical shell, retouch the most thorny difficulty of perforating steel pipe outline line and do, workman does pore Active contour model with the steel pipe head of different angles, with paintbrush, along model, on cylindrical shell, retouches.This method is difficult for holding major axis and the horizontal angle of each different pore hole shape.
There is following defect in above-mentioned process:
1, efficiency is low, draws one by one coordinate points speed slow with ruler on cylindrical shell;
2, easily make mistakes, with ruler measurement, easily misunderstand size;
3, the setting-out of egg shape outline line is inaccurate, holds bad its hole long axis and horizontal angle, needs mowing again in tubing process, is difficult to once find accurately and put in place.The egg hole local gap having after mowing is for the second time excessive, causes the welding amount of filling up large, and presentation quality is bad, waste wlding and artificial.
Summary of the invention
The object of the invention is, the problem existing for above-mentioned pore line position fixing process, provides a kind of boiler barrel pore face mold and preparation method thereof, improves production efficiency and the quality of boiler pore manufacturing procedure, reduces labor strength.
For achieving the above object, the scheme that the present invention adopts is: utilize computer and relative program, by the designing requirement of boiler barrel pore in computer, set up the 3-D graphic corresponding with boiler barrel, be then launched into X-Y scheme, revise lines, by pore distribution subregion determine each block datum line, change into polar plot, change into engraving program, on face mold material, carve hole outline line in block and datum line, making pore face mold.
Face mold material adopts the plastic plate of 0.5~1.0mm.
The beneficial effect of the boiler barrel pore face mold that the inventive method is made:
1, size is accurate: the pitch-row marking, position, hole size are accurate, and scale error is able to controlled, and egg type pore outline line is accurate;
2, efficiency is high: take 1t vertical boiler as example, with ruler measurement line, two people coordinate needs 6 hours, and two people of model line that make by the method coordinate and only need 1 hour, and effect improves 6 times;
3, be difficult for makeing mistakes: as long as model positioning datum aligns with positioning datum on cylindrical shell, can retouch line, reduce the factor of makeing mistakes of artificial measurement;
4, cylindrical shell pore does not need secondary mowing: because three-dimensional modeling has reflected the real space state that water-fire pipe is installed, pore position outline line on its cylindrical shell has obtained accurate reflection, the outline line of retouching out by model carries out flame cutting, settle at one go, do not need secondary mowing, fit-up gap uniformity, is improved the weld appearance quality of water-fire pipe and cylindrical shell.
5, model is reusable, is applicable to batch production operation.
Accompanying drawing explanation
Fig. 1 is boiler body and water-fire pipe syndeton schematic diagram;
Fig. 2 is the boiler pore face mold subregion schematic diagram of making by preparation method of the present invention;
Fig. 3 is the wherein face mold schematic diagram of a block of boiler pore of the present invention;
Fig. 4 is boiler barrel pore face mold preparation method process chart of the present invention.
In figure: 1-hole outline line, 2-datum line.
The specific embodiment
Below in conjunction with instantiation, step of the present invention is elaborated:
1, for a certain model boiler of producing, first utilize computer and Solidworks program, by this boiler barrel pore designing requirement, in computer, set up the 3-D graphic corresponding with boiler barrel;
2,3-D graphic is launched to change into X-Y scheme, by pore distribution subregion piecemeal, in exemplary plot, be divided into Si Ge district, as shown in Figure 2;
3, the solidworks X-Y scheme in launching is saved as to CAD format chart;
4, two-dimentional CAD figure is repaired, Delete Shape launches the rear unnecessary lines that occur, determines the datum line of each block model;
5, CAD format chart is changed into CorelDRAW polar plot form, then editor converts Carving Machining program code to;
6, all outline line hole 1, hole and datum lines 2 in Carving Machining block, make pore face mold, and each block is made an independent model, mark area code on model.
Technological process as shown in Figure 4
This routine face mold material adopts the macromolecule composite plastic plate of 0.7mm thickness, also can adopt as required other durable material, as aluminium sheet, and steel plate etc.
Workman uses this model process as follows:
1, the actual cylindrical of measurement products cylindrical shell is divided into the circumference arc length quartering and determines azimuth reference;
2, according to product design document, determine short transverse benchmark;
3, by longitudinal benchmark of this model and horizontal direction benchmark alignment cylindrical shell azimuth reference and altitude datum;
4, with magnet, paste model is pressed on cylindrical shell fixing;
5, with scriber or metal marker, along the hole profile of model engraving, on cylindrical shell, retouch line;
6, take off model and by the outline line of retouching, cut hole on cylindrical shell.
Non-radially pore model design and manufacture technology of the present invention has been applied to the profile line of 0.5t, 1.0t vertical boiler cylindrical shell, and line quality, operating efficiency have obtained obvious improvement.The inventive method, except making the face mold of boiler body hole group, is equally also applicable to make the Non-radial holes face mold of other revolving body surface.
