An ejecting system for a workpiece from a die cavity in a stamping machine is disclosed. The ejecting system has a spring plunger mechanism to fetch the workpiece from the die cavity of the die platen of the stamping machine. The spring plunger mechanism is provided with a picker which is integrated with a vacuum system to hold the workpiece. Underneath the spring plunger mechanism, there is an actuator, including a positioning sensor, for triggering both synchronous upward and downward movement of the linear actuator to the punch of a die set.

A sheet metal bending machine includes a sheet metal presser defining a first support surface supporting a first sheet metal portion, a bending punch movable with respect to the first support surface between a passive position, in which it is raised with respect to the first support surface, and an active position, in which it is pressed against the first support surface to lock the first sheet metal portion on the sheet metal presser with a punch edge, and a bending die defining a second support surface. The presser and the die are movable with respect to one another substantially in parallel with a direction transverse to the first and second bending edges to switch from the partial to a complete sheet metal bending configuration, in which the distance is reduced to press partially curved section towards said punch edge, thereby deforming it further and increasing the curvature of sheet.

A machine for bending a casted or stamped component into compliance with dimension and tolerance requirements, includes a base and at least one fixed holding device coupled to the base and configured to hold a corresponding datum of the component. The machine further includes at least one bending device coupled to the base and configured to engage a corresponding bending datum of the component, and a control system configured to control the at least one fixed holding device and the at least one bending device during a manipulation routine. The at least one fixed holding device is configured to hold the component in a predetermined spatial orientation relative to the base. The at least one bending device is configured to plastically deform the component.

A method for manufacturing an aluminum case of a battery includes: attaching an insulating layer to at least one surface of the plate body with an adhesive layer, wherein the adhesive layer is disposed between the insulating layer and the plate body; stamping, before the adhesive layer is cured, the plate body coated with the insulating layer to form the aluminum case in a predetermined shape, wherein during the stamping of the plate body, the insulating layer is movable relative to the plate body since the adhesive layer is not cured; and curing the adhesive layer after the stamping of the plate body is completed so that the insulating layer is fixed to the plate body, thereby avoiding detachment of the insulating layer and the plate body on the aluminum case.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.
