Summary of the invention
The object of the invention is to consider the problems referred to above and a kind of waste of material that can reduce in the course of processing is provided, and the high voltage transformer of microwave oven iron core of enhancing productivity is with the blanking method of lamination.
Technical scheme of the present invention is: the high voltage transformer of microwave oven iron core of the present invention blanking method of lamination may further comprise the steps:
1) with width is the coiled strip uncoiling of W, and dismiss two along the I shape sheet metal of coiled strip length direction center line symmetry along coiled strip length direction subpunch, the length L 1 of two I shape sheet metals equals the width W of coiled strip, the width L2 of two I shape sheet metals equals the sixth of coiled strip width W, after washing out two I shape sheet metals, form on the coiled strip after the uncoiling two be parallel to each other, along the slot of coiled strip length direction center line symmetry, the distance L 3 between two slots equals 1/3rd of coiled strip width W;
2) in the step 1) two slots of stamping-out as location hole, two rivet holes of stamping-out on the coiled strip after the uncoiling;
3) in the step 1) two slots of stamping-out as location hole, take slot along be cutting off line perpendicular to coiled strip length direction and the center line that is positioned at the center of slot, cut off, form E shape sheet metal, simultaneously on follow-up uncoiling coiled strip, fall two I shape sheet metals by the step 1) stamping-out, distance L 4 between the slot of twice stamping-out in front and back equals 1/3rd of coiled strip width W, and the height H of E shape sheet metal equals 2/3rds of coiled strip width W, i.e. H=2W/3;
4) two slots of new stamping-out take the center line between the slot of twice stamping-out in front and back as cutting off line, form E shape sheet metal, simultaneously two rivet holes of stamping-out on the coiled strip after the uncoiling as location hole after cutting off in the step 3);
5) repeat above-mentioned steps 3) and step 4), the continuous stamping of realization E shape sheet metal and I shape sheet metal.
The present invention can realize decreasing stamping-out without material in the EI sheet stamping-out process owing to adopt the direct stamping-out of forms part of two E shape sheet metals to become I shape sheet metal, improves the production efficiency of EI stamping-out process.The present invention can reduce the waste of material in the course of processing, and enhances productivity.The present invention is the blanking method that a kind of convenient and practical high voltage transformer of microwave oven iron core is used lamination.

Embodiment
Embodiment:
The high voltage transformer of microwave oven iron core of the present invention blanking method of lamination may further comprise the steps:
1) provide a kind of width suitable coiled strip, wherein the width of coiled strip equals W, and in the present embodiment, width W is 96mm, and thickness is 0.5mm, as shown in Figure 3.
2) coiled strip 1 after the uncoiling is washed out two along the I shape sheet metal of coiled strip length direction center line symmetry along the coiled strip length direction, the length L 1 of I shape sheet metal equals the width W of coiled strip, be 96mm, width L2 equals the sixth of coiled strip width W, be 16mm, on the coiled strip between two parallel slots distance L 3 equal 1/3rd of coiled strip width, be 32mm, shown in Fig. 4 a, 4b.
