Abstract: A bi-directional and double-punch balanced high-speed bodymaker includes a punch driving mechanism and blank pressing mechanism, wherein: the punch driving mechanism includes a crankshaft, two identical connecting rods, slide rails, sliders and punches. The crankshaft is rotationally supported by a bearing, and the crankshaft has a first crank, second crank and first and second blank pressing cams. Compared with the prior art, the swing lever and secondary connection are removed from each set of punch driving mechanism, simplifying the structure while maintaining all original functions, constituting omitting elements. It adopts two blank pressing cams and arranges the first blank pressing cam driving point of the opposite the second blank pressing cam driving point, and finally, the directions of the first and second torque are opposite and counteract each other, to maintain balance of overall torque on the plane passing the crankshaft axis during the operation of the bodymaker.

Abstract: A resealable easy open lid that is composed of a lid and a pull ring riveted on the lid; the rear end of the pull ring is composed of an outer ring body and an inner tongue of the pull ring; the tongue is provided with an arched deformation area along the edge; the arched deformation area is an edge inclined to the inner side of the lid which is formed by die stamping on the tongue of the pull ring; the tongue is provided with a part arching to the outside of the lid; after the pull ring is rotated around the riveting point, the tongue of the pull ring covers the opening zone, and when the middle part of the tongue is pressed, the arched deformation area can be overturned and deformed to make it contact with the edge of the opening area to seal the area.

Abstract: A pressure resistant basic shell, easy open end and can with easy open end, wherein the basic shell consists of a can seaming portion, a countersink portion, a ferrule arc portion, an upward extension portion of ferrule and a center panel from periphery to center in the cross section; the countersink portion also consists of a sixth arc portion and a second straight portion, and the sixth arc portion and the second straight portion are connected in a tangent way, and the second straight portion and the ferrule arc portion are connected in a tangent way; the center of the sixth arc portion is located below the upper surface of the center panel. The break probability under the failure of pressure resistance is lowered to 0.05%˜2.5%, which significantly improves the safety of use.

Abstract: A stamping device and a multi-lane shell stamping system, wherein the stamping device is used for simultaneous stamping of multiple shells, including a plurality of stamping die sets arranged in an array. Each stamping die set includes an upper die and a lower die. The upper die is integrally formed, and the outer diameter of the upper die is larger than that of the lower die, and the bottom edge of the upper die forms a locating part for the curling of the shell to be processed. The device and system eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. It also adopts the method of directly increasing the diameter of the upper die, which not only avoids the mounting and dismounting of the locating cup, but also realizes the locating effect of the shell.
