Abstract: This application discloses a stamping device and a multi-lane shell stamping system, and the stamping device is used for simultaneous stamping of multiple shells, comprising a plurality of stamping die sets arranged in an array. Each stamping die set comprises 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 present invention eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. At the same time, it 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.

Abstract: The present disclosure discloses a method and a device for extracting overlapping peaks based on mode decomposition, which includes: obtaining a problem formula for finding peak values according to an between-class variance function representation, adding a penalty term and a Lagrange multiplier to the function by using an augmented Lagrange multiplier method, and transforming an optimization problem formula containing two variables and one constraint condition into an unconstrained extreme value problem containing three variables; performing quadratic optimization on the unconstrained extreme value problem and transforming the unconstrained extreme value problem into a minimization problem formula; setting a convergence condition according to the minimization problem formula, updating three of the variables in the minimization problem formula, and stopping iteration until the preset convergence condition is met; wherein a final calculation result is peak values of two spectral axial response signals when sto

Abstract: A pressing die for an uncurled shell of a pressure-resistant easy open end, and the lower die mainly consists of a lower die base, a lower die core ring, a lower die core, a lower pressing ring and a lower blade; the upper die mainly consists of an upper die base, an upper die core, an upper inner forming ring, an upper outer forming ring and an upper blade, wherein: for the new easy open end type, the top of the lower die core ring of the lower die was designed to be the contour matching the new can end type, and the upper outer forming ring and the upper inner forming ring of the upper die were designed to the contour and suspended portion matching the lower die core ring of the lower die.

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.
