Problems solved by technology
Since there is no device for positioning the polyester film on the workbench of the CNC plotter, after the mold line drawing is completed, if the mold line needs to be modified, the polyester film cannot be re-placed on the original drawing position, and it cannot be realized. Modify the mold line with a CNC plotter, but can only be modified by hand
Due to the low efficiency and precision of manually modifying the mold line, it affects the production efficiency and precision of the mold line
For some mold lines that cannot be modified by hand, the entire mold line can only be redrawn, which not only increases the repetitive drawing work, but also wastes the drawing materials of the mold line and increases the production cost

Embodiment Construction
[0020] a kind of like figure 1 The die line of the two-dimensional figure shown is modified as figure 2 The method for the die line of the two-dimensional figure shown is implemented through the following technical solutions:
[0021] 1) Draw the X-axis direction line x and Y-axis direction line y of the plotter on the workbench (1) of the plotter;
[0022] 2) On the X-axis direction line x and the Y-axis direction line y, draw a number of equidistant scale lines a with a distance L of 1mm~1000mm;
[0023] 3) Erase the line (b-1) that needs to be changed on the polyester mold line (2);
[0024] 4) Spread the polyester mold line (2) on the workbench (1) of the plotter so that the bottom edge of the frame (2-1) of the polyester moldline (2) is on the plotter workbench (1) The X-axis direction line x coincides, and the left edge of the frame (2-2) coincides with the Y-axis direction line y on the plotter workbench (1);
[0025] 5) Delete all the lines that do not need to be ...

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 [0001] The invention relates to a method for modifying polyester mold lines with a plotter, which belongs to the technical field of mechanical drawing. Background technique [0002] In the traditional production mode, the mold line is drawn by the draftsman on the steel plate. With the development of digital production technology, the mold line is mainly drawn on the polyester film by the numerical control plotter at this stage. The mold line is composed of a drawing frame and part graphics. When drawing the mold line, spread the ester film on the working table of the drawing machine, and then draw the graphics. Since there is no device for positioning the polyester film on the workbench of the CNC plotter, after the mold line drawing is completed, if the mold line needs to be modified, the polyester film cannot be re-placed on the original drawing position, and it cannot be realized. Modify the mold line with a CNC plotter, but can only be modified by hand....
