Description of the invention (3) The arc-white combination, Shiyang, '^ ..., method of effective alignment, will greatly increase the number of defective products. [Summary of the Invention 1] The invention is mainly to provide a sheet metal bending process The method is tied to the plate of the concave section, and the pre-pressing of the imitation fen concave fold is pre-compressed on one or both sides of the curved section to be f, so that when it is bent to form the curved section, It has a clear 夂 4 and alignment of the desired concave fold. In addition to making the concave fold of the curved arc segment more accurate, f can be used to effectively prevent springback or deformation after the concave fold of the semicircular arc segment is formed. Make sure that the shape of the arc segment after bending is the most complete and correct. It can be bothersome and inconvenient when the convex arc pieces on both sides are used for corresponding welding. ] Triggering and pressing, it is not necessary to greatly reduce. [Embodiment] First, please refer to the first figure-^ ^ ① The implementation steps of placing the plate ⑴ on the lower invention are as follows: 1) and the upper mold (4). Click on and fit a V-shaped notch on the top (3 Figures-the first and second steps shown in the figure: 'form a concave folded section (11) [such as ② then according to the arc length of the curved arc section (° with the other V At the two ends, the mold is pre-compressed at the two ends by using the lower mold (3) shallow concave folds (1 3 /, Γ) and the upper mold (4)]. 4) [As shown in the third and fourth of the first figure] ③ Between the two shallow concave folds (1 3), the combined deep groove (5 1) and the lower die (5), the upper die (6) of the semi-circular section (丄 5) is punched (6) ] 〔As shown in steps 5 to 7 of the first picture! 222384 V. Description of the invention (4) ④ The first program is used to process the plate (1) The concave and folded sections on both sides of the plate pass the above processing steps. For implementation, the distance between the two shallow concave folds (Work I) and (14) is the fox length (12) of the semicircular segment (15) to be concave fold, and the two shallow concave folds (13), (14) Pre-formed concave folds Type, when the semi-circular segment (1 5) is concavely folded, as shown in the rightmost part of the figure, so that the two flat-plate segments (13), (14) and the semi-circular segment (1 5) form a fairly correct and not skewed shape. Correctly, it will not open and open, and the flat section (16), (17) and the semicircular section (work) are quite neat and clear, making the finished product more beautiful and solid. And the most important thing is, The use of these two shallow concave folds (i 6) and concave fold semi-circular segments (15) 'can make the finished product more neat and accurate according to the shape of the ink, so that the two sides need not be manually disturbed and unfavorable when welding.' Big ㉟ reduces unnecessary sleepiness of pre-processing afterwards: and inconvenience. Furthermore, the shallow concave fold (1 3: after the concave fold, the semicircle 瓞 ric :, ^ no concave fold visual inspection and falling as fixed # 又 (1 5) It is relatively easy to work on a punch-person f position, so that the concave position of the semi-circular segment (1 5) is more dream-breaking. 1 Eliminate the lack of habit. 丄 97 four prayer position is more accurate. Tai i nn i, and its disclosed examples have confirmed that * the use effect reached the pre- Jingjing has not been disclosed in Shenshe i structure & not only has not been seen in similar products "Yi, Jia" Yue Ze's has fully complied with the Yangding toilet moxibustion of the Patent Law, and according to the law, the rules and requirements for the invention of the special sacrifice must be paid by 4 payers, and it is a sense of virtue.
