[Prior Art] According to the traditional technology of metal sheet processing, no matter the stamping, even punching, bending, etc., basically, the use of the mouth matching mold can achieve the desired shape, ^ cold processing, It is a very common technology. Age, on the other hand, workpieces or products that are machined into curved and curved holes, such as electronic or electrical parts, can be used for ventilation or heat dissipation. Basically, Yu Da has a polymer material injection method. Of course, the texture is inferior to the sheet metal forming. The reason is that it is not easy, and if the sheet is punched by the conventional method, Some of the holes in the curved surface will be deformed, and the appeal will be made to show the lack of beauty. [Invention] In view of this, the inventor has been engaged in machine experience for many years, and has been studying hard to overcome the above-mentioned shortcomings, and then made the "metal plate products with curved holes" in this case and further reveal the case. The specific technical content, the first type, wherein, Figure 1 is the manufacturing flow chart of the present case, Figure 2 is the figure, Figure 3 is the semi-finished product of the pressed type, and Figure 4 is the second and its production method, especially the curves are Deep pumping or so-called design should be well-designed, and the outer edge of the outer edge of the plate or the curved surface of the hole will be naturally processed compared with the gold metal plate and then deep drawn. Therefore, in the visual machining design The second test, the creation of its system." Read the first tea, read the materials in this case, press and punch,

As shown in Fig. 3, the residual pressure type cutting step 3 is to use the mold to squeeze up and down: the edge G cuts off, and if the front side, that is, the horizontal plane: the two can also taste 丨丨ra丨丨丨η - , when working with a hole, use this V to punch and shape, but this is also a well-known skill, so not page 6 1261002 • V. Description of the invention (3) to be described; and semi-finished products formed at this stage The J system is shown in Fig. 4. Since it is a vertical punching hole, each plane hole is a theoretically perfect circular shape. The slitting step 4 is to use the mold to cut the pair of workpieces from the middle to form two workpieces or semi-finished products, as shown in Fig. 5, and at this time, the mold can also be used to punch the front or the plane holes, in fact, the semi-finished products can be further It is an additional step of the conventional process, which is an additional step of the conventional integer step, and therefore is not intended to be repeated. The arc punching step 5 is to design the separated semi-finished crucibles obtained by the above-mentioned, through the mold design, so that the cut surface (line) of the arc surface of the punching portion is |water level and placed in the lower mold, and punched by the upper mold To form the intended circular hole, as shown in Figure 6. However, if it is not limited to a circular hole, the hole of the curved surface position is the smallest deformation of the front side (vertical) view, and if the plurality of rows of the curved surface are punched, the mold design can be utilized to respectively make The curved surface to be stamped is a horizontal plane to punch out the hole 最小 which is the least deformed, thus forming an article as shown in FIG. In fact, as mentioned above, the hole in this case is not limited to a circular hole, but it is also a hole of other shapes, such as a square, a triangle, a hexagon... depending on the design of the die. Therefore, through the implementation of the present case, in addition to solving the problem of the conventional hole processing method, the method is easy to be deformed, and the appearance of the metal product with the curved surface can be obtained. The disclosure of the present invention, which is a preferred embodiment, is a part of the patent right of the present invention, which is derived from the technical concept of the present invention and is easily inferred by those skilled in the art.
