A quick-change die assembly for a necker machine includes an outer die mounting, an outer die, an outer die quick-release coupling, an inner die mounting, an inner die assembly, and an inner die quick-release coupling. The outer die is coupled to the outer die mounting by the outer die quick-release coupling. The inner die assembly is coupled to the inner die mounting by the inner die quick-release coupling.

In a case where a vacant space exists on only one side in a holder area of a stocker positioned at an exchange position, a first upper tool exchange unit is first moved in the left-right direction, and located in the vicinity of the vacant space. Next, the first upper tool exchange unit is moved forward and thereafter moved to the left, so that a tool retention member of the first upper tool exchange unit is brought into contact with one side surface of a tool. Then, under the contact state, the first upper tool exchange unit is moved to the right until the other side surface of the tool abuts on a stopper.

A seaming roll for sealing a container includes a rotation body rotatable on a bolt for sealing the container. The rotation body includes a first basic side and a second basic side different from the first basic side and a bearing. The bolt is arranged on the bearing via the first basic side such that the rotation body can be rotated about the bolt in the circumferential direction of the second basic side when the container is sealed. The seaming roll further includes an exchangeable seaming profile for seaming a container lid with a body of the container and a fastening mechanism. The exchangeable seaming profile is detachably connected to the rotation body via the fastening mechanism.

A method of forming a vehicle panel includes deforming a sheet metal workpiece between stamping tools to form a first and second edges that converge at a corner of the workpiece's main surface. The first edge is defined by a junction of the main surface and a first flange. The second edge is defined the main surface and a second flange. Forming the first and second edges includes deforming the workpiece so that the second flange has a first region bent to a first angle relative to the main surface and an unwinding region bent to an angle that unwinds from the first region as the second flange approaches the corner. The method includes deforming the workpiece between a second set of stamping tools that deform the first flange and the unwinding region of the second flange until the first and second flanges are bent greater than 90°.

A bending system includes a greasing unit configured to move in a right-left direction by way of a moving operation of an external operation member and to supply grease to a sliding contact part of a tool holder, and a greasing unit holder provided on one side in a right-left direction of a table and configured to support the greasing unit. The greasing unit includes a greasing unit main body, and an application member provided on the greasing unit main body and formed in a shape corresponding to the sliding part of the tool holder, the application member being configured to be able to be impregnated with the grease.

A multi-directional multi-cam press device may include a cam base fixed to the lower mold, a first cam slide provided to slide forwards and backwards along a first direction of the cam base, at least a first punch unit provided in the first cam slide along a first direction, a cam drive fixed to an upper mold configured of moving in a vertical direction with respect to the lower mold, and making cam contact with the first cam slide, a second cam slide provided in the cam drive to move forwards and backwards in a second direction perpendicular to the first direction and in contact with the cam base side, and at least a second punch unit provided on the second cam slide along a second direction.
