A linear apparatus for forming a can opening, including: a working tabletop, a plurality of necking machining stations are arranged on the working tabletop; each necking machining station is provided with a can body positioning recess for positioning a can body; the can body positioning recess is internally provided with a vacuum suction hole; a vacuum chamber is arranged below the working tabletop; the vacuum chamber is in communication with the vacuum suction hole; a necking machining device is correspondingly arranged on each necking machining station; further: a moving device, and the moving device acts on the can body positioned in the can body positioning recess and is used for moving the can body on the stations onward by one station. The apparatus has the advantages of simple structure, low cost, small occupied space and convenient maintenance, and is the best choice for manufacturers with low production speed requirements.

The present application provides a necking method, a necking apparatus, and a battery manufacturing device. The necking method is used for forming a necked portion on a shell with an open end. The necking method includes: forming an annular groove on the shell, where the annular groove extends in a circumferential direction of the shell; and expanding a width of the annular groove towards the open end to form the necked portion. The technical solution of the present application can effectively reduce deformation of the shell, ensure safety of an electrode assembly, and improve performance stability of a battery cell. Meanwhile, pre-necking the shell effectively reduce a risk of deformation resilience of the shell after the necked portion is formed, thereby improving machining precision and structural stability of the necked portion.

A necking and flanging apparatus includes: an inner mold; a necking piece, disposed around the inner mold, where the necking piece is movable along a radial direction of the inner mold, and the necking piece is configured to coordinate with the inner mold to form a necked portion on a housing; and a press-fit piece, disposed around the inner mold, where the press-fit piece is movable along an axial direction of the inner mold, and the press-fit piece is configured to fit the necking piece to press and flatten the flanged portion of the housing.

A machining device for an element to be machined includes a moving unit, a machining unit and a control element. The moving unit is provided with an acceleration unit. The control element and the acceleration unit are designed so that a movement of at least one part of the acceleration unit with at least one component of movement transverse to the direction of movement of the moving unit is mechanically associated with a movement of the moving unit relative to the control element. The acceleration unit is designed so that producing a relative acceleration of the machining unit in relation to the moving unit in the direction of movement of the moving unit is mechanically associated with the movement of at least said part of the acceleration unit.

A turret head assembly for forming an article includes at least one smoothing roller. Each of the at least one smoothing roller is rotatably mounted on a respective at least one roller support member. The turret head assembly further includes an upper ring member and a lower ring member. The upper and lower ring members include respective apertures located in the centers thereof. The at least one roller support member extends between the upper ring member and the lower ring member. The turret head assembly further includes a turret head-assembly support member defining a turret-head axis. The turret-head-assembly member extends through the respective apertures in the upper and lower ring members.

An ultrasonically vibrated die comprises a generally cylindrical die ring supported by a coaxial resonant mounting tube. The die ring is vibrated in a radial bending mode of vibration, in which an end surface of the die ring oscillates between a concave and a convex state. The mounting tube joins the end surface of the die ring at a radius R where the amplitude of the oscillation of the end surface is at a minimum, in order to reduce transmission of the vibration into the mounting tube.
