Abstract
The invention provides a method for modifying a polyester module line through a drawing machine. The method comprises the following steps: drawing an X axle and a Y axle on a working table of the drawing machine, and drawing a plurality of equidistant scale marks on each of the X axle and the Y axle; erasing lines required for modifying on the polyester module line; tiling the polyester module line on the working table of the drawing machine so that the bottom side line of a picture frame is superposed with the X axle on the working table, and the left side line of the picture frame is superposed with the Y axle; deleting lines at a part unnecessary to modify in a new edition module line graph by only reserving the lines at the part required for modifying and a vertex at the bottom left corner of the picture frame, and saving as a drawing file in a dxf format; importing the saved drawing file into the dxf format in operation software of the drawing machine, and then drawing after the vertex at the bottom left corner of the picture frame is defined as a drawing original point. The method for modifying the polyester module line through the drawing machine is simple in steps and easy to operate.
Description
Technical field
The present invention relates to the method for a kind of draught machine amendment polyester loft, belong to mechanical drawing technical field.
Background technology
In traditional mode of production pattern, loft is completed on steel plate by the personnel of drawing, along with the development of digital production technology, present stage loft mainly apply calcomp and draw on polyester film.Loft is made up of draw frame and parts pattern, when drawing loft, being laid in by ester film on the workbench of draught machine, then carrying out graphic plotting.Due on the workbench of calcomp not used for location polyester film device, after loft is completed, modify as needed mutual-mould line lines, then polyester film cannot be reapposed on former drawing position, just cannot realize revising loft with calcomp, and can only modify by hand.Because the efficiency and precision of revising loft are by hand very low, and then have impact on production efficiency and the precision of loft.For the loft that some cannot be revised by hand, whole loft can only be repainted, not only increase repeated Plot Work, more waste the drawing materials of loft, add production cost.
Summary of the invention
The present invention proposes the method for a kind of draught machine amendment polyester loft, and loft revised by realization calcomp, and improve change precision and the efficiency of loft, the present invention implements by the following technical programs:
1) on the workbench of draught machine, draw the X-direction line x of draught machine, Y direction line y;
2) on X-direction line x and Y direction line y, the equidistant graduation mark that some distances are 1mm ~ 1000mm is drawn respectively;
3) the lines erasing will polyester loft needing change;
4) be laid on the workbench of draught machine by polyester loft, sideline bottom the picture frame of polyester loft is overlapped with the X-direction line x on draught machine workbench, and on the left of picture frame, sideline overlaps with the Y direction line y on draught machine workbench;
5) all lines of change part that do not need in new edition two dimension lofting drawing are deleted, only retain and need the lines of change part and the summit in the picture frame lower left corner, and save as dxf form plotting file;
6) in draught machine function software, import the dxf form plotting file of preservation, the summit in the definition picture frame lower left corner is draw after drawing initial point, and namely polyester loft has been revised.
Beneficial effect of the present invention: by drawing X-direction line and Y direction line on the workbench of draught machine, realize the location of polyester loft on draught machine workbench, by the method for draught machine amendment polyester loft of the present invention, step is simple, be easy to operation, improve amendment precision and the efficiency of loft, save material cost.

Detailed description of the invention
The loft of X-Y scheme is modified as a method for the loft of X-Y scheme as shown in Figure 2 as shown in Figure 1, implements by the following technical programs:
1) on the workbench (1) of draught machine, draw X-direction line x, the Y direction line y of draught machine;
2) on X-direction line x and Y direction line y, the equidistant graduation mark a that some distance L are 1mm ~ 1000mm is drawn respectively;
3) lines (b-1) erasing will polyester loft (2) needing change;
4) polyester loft (2) is laid on the workbench (1) of draught machine, sideline (2-1) bottom the picture frame of polyester loft (2) is overlapped with the X-direction line x on draught machine workbench (1), and on the left of picture frame, sideline (2-2) overlaps with the Y direction line y on draught machine workbench (1);
5) all lines of change part that do not need in new edition two dimension lofting drawing are deleted, only retain and need the lines (b-2) of change part and the summit A in the picture frame lower left corner, and save as dxf form plotting file;
6) in draught machine function software, import the dxf form plotting file of preservation, the summit A in the definition picture frame lower left corner draws after drawing initial point, and namely polyester loft (2) has been revised.
When drawing by the dxf form plotting file preserved with draught machine, first draw a cross spider in the picture frame lower right-hand corner of polyester loft (2), then by needing the lines (b-2) of change part to be plotted on polyester loft (2), complete with draught machine amendment polyester loft (2).
Claims (1)
1., by a method for draught machine amendment polyester loft, it is characterized in that comprising the following steps:
1) on the workbench (1) of draught machine, draw X-direction line x, the Y direction line y of draught machine;
2) on X-direction line x and Y direction line y, the equidistant graduation mark a that some distance L are 1mm ~ 1000mm is drawn respectively;
3) lines (b-1) erasing will polyester loft (2) needing change;
4) polyester loft (2) is laid on the workbench (1) of draught machine, sideline (2-1) bottom the picture frame of polyester loft (2) is overlapped with the X-direction line x on draught machine workbench (1), and on the left of picture frame, sideline (2-2) overlaps with the Y direction line y on draught machine workbench (1);
5) all lines of change part that do not need in new edition two dimension lofting drawing are deleted, only retain and need the lines (b-2) of change part and the summit A in the picture frame lower left corner, and save as dxf form plotting file;
6) in draught machine function software, import the dxf form plotting file of preservation, the summit A in the definition picture frame lower left corner draws after drawing initial point, and namely polyester loft (2) has been revised.
