北京機加工廠淺談沖壓加工件的工藝特點

很多产品的结构件或电子外壳，经过前期的样件及小批量机械加工后，市场反映良好，会有大批量的订单需求，

那麽，大批量零件定制加工時，如果能用沖壓工藝來完成的話，將是不二選擇。北京沖壓件加工的工藝特點有哪些呢，

主要由以下四点来分析。

（1）冲压工件的尺寸精度由模具来确定，具有一模一样的特征，所以批量生产时质量稳定，互换性好。

　　（2）由于是用沖壓模具來拉伸加工的工件，所以零件的薄壁、分量輕、剛性好、結構外形複雜這些難點可以有效的

得到解決。

　　（3）沖壓加工一般屬于冷成形，也不像切削的北京機械加工那樣需要去除大部的材料，沖壓件對材料也是一種節約。

　　（4）北京沖壓加工的特點重要的一點就是生産效率高，根據壓力機噸位大小的不同，可以制定單次沖壓出幾件五金件來。

由于冲压工艺具有这么多的良好特点，在北京精密零件制造實踐中很多行業都有應用。例如，航空航天、軍工裝備、

電子通信、軌道交通、建築設備等産業都有沖壓加工。在現代生産生活中，不但産業界廣泛用到它，而且現在人們甚至

每天直接與沖壓産品發生直接或間接的聯系。沖壓可制造我們日常生活中的手表上的小型精密零件，也可制造飛機、

輪船上的大型加工件。

"And so here you are in this awful fix." "Those letters--to the newspapers?" "Yes! oh, yes, yes!" His eyes danced, and a soft laugh came, as happy as a child's. "The surgeon is yonder, he will tell you." The man laughed silently, horribly, his body twisting as if set on wires. Then, two and two, carrying on their shoulders heavy trays piled with presents, women mount the steps of the house, the bridegroom standing at the bottom. The bride's mother comes forth to meet them in a dress of pale-coloured China crape covered with a fine white saree. She waves her closed hand three times over the gifts, and then, opening it, throws rice on the ground. This action[Pg 16] she repeats with sugar and sweetmeats, and finally with a coco-nut. And each time she empties her hand a naked boy appears from heaven knows where, gathers up what she flings on the ground, and vanishes again, lost at once in the shadows of the garden. “Have you brought him back?” "Old Manuel he told me. You don't know him. It's an old Greaser, friend of mine. He don't want no one to tell he told, they'd get after him. But it's so, all right. There's three of them." BY the time Shorty had gotten the boys fairly tented, he was ordered to take a squad and guard some stores at the Division Quartermaster's. Si, instead of going on camp-guard, had to go out to the grand guard. When he came back the next morning the Orderly-Sergeant said to him: "What do you mean, good care of him?" she said. But Albin was gone, into the main body of the party, a melee confused enough so that he was lost in twenty steps. Greta turned back almost hopeless eyes. "Of course," the voice said. "We can prepare—as I am doing. There is nothing else for us, not any more. Idealism has taken over, and what we are and what we've done can go right on down the drain. Norma, you're a bright girl—" "But I heard what the doctor said to you." "F?ather's after our land," said Tilly, and shuddered. "My friend," said Manlove; "it matters little now whether you agree with your brethren or not, the woman is at this moment dying! The verdict is, therefore, of little moment to her—she can never be brought into court to receive judgment—guilty or innocent, the law can have nothing to do with her; but I would advise you to look to yourself, you will not be released till she is dead. Your brethren are accustomed to fasting, but you look ready to drop from your seat: and, if the woman linger many hours, you will certainly be guilty of felo de se."
