The present invention is the same as the above-mentioned upper cover, and is applied to the same mother mold as the above-mentioned upper cover, and the bottom end of the inner mold is also provided with a central cone and its periphery and the relative position of the desired formed lower cover string. a circular groove; the outer edge of the lower cover male mold is also equivalent to the outer diameter of the shape of the lower cover main body, and the bottom end is respectively provided with a geometric punching block relative to the position of the formed lower cover, and the metal material is placed in the female mold. In the inner mold, the metal material is directly punched in the inner mold by the lower cover male mold, so that the metal material flows to the circumference wall of the inner mold according to its extension property, and the center cone of the bottom portion of the inner mold is applied at the same time. And the circular groove, and the periphery of the inner mold, • to form a lower cover body and a lower cover 'column, and form a central slot by the central cone at the center of the lower cover pipe, and by the geometrical block Forming a geometrically shaped notch in each of the four corners of the lower cover body; applying a mold, the inner mold is opened in the same shape as the lower cover body, and the inner mold has a front section inner diameter and a rear section inner diameter, the front section The inner diameter is slightly larger than the inner diameter of the rear section, so that the rear section The space of the inner diameter is equivalent to the size of the upper cover required, and then the upper cover body is forced into the inner diameter of the front section by a die to pass the diameter φ in the rear section, and the metal stretchability is applied to the inner diameter through the rear section. The peripheral surface of the upper cover body is formed into a smooth surface without additional milling machine processing to reduce the processing cost; thereafter, a ring groove formed by the periphery of the lower cover pipe column and a machining of the inner slot hole are formed by a CNC lathe. The surface is removed, and the cover hole perforation is respectively drilled into the central axis of the geometrically lacking groove of the four corners of the lower cover body to complete the finished product of the lower cover, thereby achieving the benefits of material saving, cost reduction and rapid manufacturing. Therefore, by means of the conventional assembly method, the upper cover and the lower cover can be respectively covered on both ends of the hydraulic cylinder (known omitted), and can be inserted into the two ends of the hydraulic cylinder through the lower cover plug of the upper cover and the lower cover. Covering the leakage, and then screwing through the perforation of the upper cover and the perforation of the lower cover, so that the screw head is placed at the position of the geometrical missing slot 7 1357363, and only one end of the nut can be tightened to complete a hydraulic pressure. Cylinder combination (known omitted). 4. When the lower cover of the present invention is stamped and formed in the mold, the punching surface of the lower cover male mold is respectively provided with a geometric punching position with respect to the punching position to be drilled in advance at the four corners, so that the position is directly punched out to the geometric shape. a groove, and then a cover perforation is drilled in the geometrically shaped notch to provide a screw for inserting the lower cover through the geometrical notch for the screw head to accommodate the limit, so that only one tool is used for the assembly. Lock the other nut to provide quick and easy assembly. [Embodiment] ® Due to the shape of the upper and lower covers, depending on the shape of the required hydraulic cylinder, in order to make the invention easy to understand, it is assembled at both ends of the most typical hydraulic cylinder. The upper and lower cover methods are explained. Please refer to the third figure-E. Since the hydraulic cylinder upper cover 31' is configured to have a flat central through hole 312', please refer to the third figure and the third figure-A, which is a cover. The male mold 1 is provided with a center punch 11 at the bottom end of the upper mold male mold 1 according to the shape of the upper cover 31' of the hydraulic cylinder, and the inner mold 21 of the female mold 2 is also according to the hydraulic cylinder upper cover main body 31 ( As shown in the third figure -B, C), a central cone 211 is disposed at the bottom of the inner mold 21, a circular groove 212 is defined in the periphery of the inner mold φ, and a metal material 3 is placed in the inner mold 21, The upper cover male mold 1 directly presses the metal material 3 into the inner mold 21; please refer to the third figure -B, C, and the above-mentioned stamping, the extension of the metal material 3 is applied to the inner and outer periphery. Forming an upper cover body 31 and a center of the inner cavity 21 in the circular groove 212 forming an upper cover pipe 311, and by the center punch 11 and the central cone 211, that is, directly forming a center in the upper cover pipe 311 Center through hole 312; see Fig. 5, Fig. 5A-C, an shaping mold 6, the inner mold 61 is opened relative to the upper The cover body 31 has the same shape, and the inner mold 61 has a front inner diameter 611 and a rear inner diameter 612. The front inner diameter 611 is slightly larger than the rear inner diameter 612, so that the space of the rear inner diameter 612 is equivalent to the required The upper cover 31 (e.g., 8 1357363, Fig. - F) is of the same size, and then the die 7 is forced into the front inner diameter 611 and then passed through the rear inner diameter 612 to apply the eight metal stretch. By shaping the inner diameter 612 of the rear section, the = perimeter is formed into a smooth surface (such as the fifth figure-B) without the need to process the sharp bed again to reduce the processing cost. Referring to the third figure-D, the shaped upper cover main body 31 passes through the outer periphery of the upper cover pipe 311 and the inner edge of the central through hole 312 through a CNC lathe, and a ring groove 3111 is formed on the periphery of the upper cover pipe column 311 (for example). The processing surface 313 of the third figure-E) is removed to form a top cover plug 3 ιι, which can be embedded in the 0-ring (known omitted) and in the central through hole, with the flat surface of the entire surface. Hole 312, (as shown in the third figure _E); please 4, 7th-F' s Xuan Shangyu main body 31 drilled in a corner of the four corners perforated sergeant ^ Cheng Yuan whole cover 31 '' available for a screw ( Conventionally omitted) 314; therefore, by the above-described method of manufacturing the upper cover and the device thereof, it is possible to achieve rapid manufacturing and reduce waste of processing procedures and waste. Referring to the fourth and fourth figures - Α, the same method as the above-mentioned upper cover 31, the same method as the above-mentioned manufacturing of the upper cover 31, the inner mold 2, the inner mold # is also provided with a central cone 211 And the periphery and the required molding: ^ cover tube ^ - (such as + fourth figure - B, C) relative to the position of the circular groove 212; the second If ί die 4 outer edge is also with the lower cover body 51 (such as The shape of the outer diameter of the fourth figure-B), the bottom end of the shape is opposite to the molding lower cover 51, (such as the fourth figure -C) respectively, a geometrical punch 41 is provided, and the metal material 3 is placed thereon. In the inner mold 21, the metal material 3 is directly stamped in the metal mold 3, so that the metal material 3 flows toward the peripheral wall of 21 according to its extension property, and the center of the bottom of the inner mold 21 is applied. a cone 211 & two J J12, and a periphery of the inner mold 21 to form a required lower cover main body 51 and a central slot 511, and a central slot 211 1 and a central slot 512 at the center of the lower cover string 511, and By the geometrical punching block 41 in the lower cover main 1357633
