Manufacturing thin-walled castings utilizing adaptive machining
A method of manufacturing a casting is provided and includes establishing desired dimensions of a nominal casting, executing a casting process to produce multiple actual castings with each of the multiple actual castings having respective dimensions that differ from each other and from the desired dimensions of the nominal casting and engaging one or more tools to adaptively machine, without rigidly-programmed toolpaths, each of the multiple actual castings to reduce the respective differences between the actual dimensions of each of the multiple actual castings and the desired dimensions.
Process for manufacturing a cast metal heat exchanger housing for a vehicle heater
A process for manufacturing a cast metal heat exchanger housing (12) for a vehicle heater having a pot-shape housing wall (14) extending in a direction of a housing longitudinal axis (L) and having a plurality of heat transfer ribs (22) extending on an outer side of the housing wall (14) in the area of a circumferential wall (16) and in the area of a bottom wall (18) of the housing wall (14) in the direction of the housing longitudinal axis (L). The process includes metal casting wherein a sprue cross-sectional area including at least some of the heat transfer ribs (22). The cast metal heat exchanger housing has an axial end face formed upon cutting off metallic material that is essentially at right angles to the housing longitudinal axis and extends into an area of at least some of the heat transfer ribs.
ROLLER CASTING METHOD AND SYSTEM FOR PRODUCING A SPIRAL STRUCTURE
The invention relates to a roller casting method for producing a spiral structure, in particular a spiral structure for use in electric machines. Molten metal is supplied between a first roller and a second roller miming opposite thereto, wherein the first roller has first teeth, and the second roller has second teeth, said first and/or second teeth having tooth flanks with cavities for receiving the supplied molten metal. The teeth are designed and aligned such that the cavity of at least one tooth is at least temporarily delimited by the surface of a tooth of the other roller when the rollers are rotating such that the supplied molten metal is molded between the teeth while cooling and is molded into a section of the spiral structure.
METHOD OF FORMING A HELIX, PERMANENT MOLD FOR FORMING A HELIX, AND HELIX
The invention relates to a method for producing a helix (2), having a step of providing a permanent mold (1) with mold halves (1.1, 1.2) which can be joined together on a mold parting line (1.5). The method additionally has a step of joining together the mold halves (1.1, 1.2) of the permanent mold (1) such that the permanent mold (1) has a cavity (1.3), which defines the shape of the helix (2) or the shape of a bent-up helix (2′), when the permanent mold is joined together, wherein the specified helix (2) or the bent-up helix (2′) has a flattened profiled winding cross-section which has two opposite flat sides (2.1, 2.1′), an outer side (2.2) and an inner side (2.3) opposite the outer side (2.2), and the mold parting line (1.5) runs at least partly along the outer side (2.2) and/or the inner side (2.1) and/or edges of the profiled winding cross-section. The method additionally has a step of removing burrs (3) extending on the outer side (2.2) and/or the inner side (2.3) and/or the edges of the cast body on the mold parting line (1.5). The invention further relates to a permanent mold for carrying out the method and to a helix which has been produced using the method or using the permanent mold.
Device for removing burrs from riser of aluminum alloy wheel
Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.
Trimming-deburring assembly
A trimming-deburring assembly includes an upper fixed plate, a lower fixed plate, an intermediate mobile plate, movable between the upper and lower fixed plates, in a vertical direction, and command and movement means for moving the intermediate mobile plate, having an electric motor and a movement group operatively connected on a top to the electric motor and on the bottom to the intermediate mobile plate. The movement group has a spindle member drivable in rotation by the electric motor, having a spindle cavity and a worm gear element provided with a worm gear cavity defined by a threaded worm gear wall, and a worm screw element at least partially housed in the spindle cavity and in the worm gear cavity, having a threaded screw wall engaged with the threaded worm gear wall to receive rotary action of the worm gear element, and a lower end operatively connected to the lower fixed plate.
Degate robot end-of-arm tool and methods of use
A method and an automatic degate system includes a fixture configured to receive a workpiece, a registration device configured to position the workpiece in a predetermined orientation and position, and a robotic arm. The robotic arm is configured to move in at least a gripping direction. The robotic arm includes a gripping device configured to engage the workpiece at predetermined locations after being moved in the gripping direction. The robotic arm also includes a support bracket, a plurality of elongate rods each having a predetermined length and extending orthogonally from the support bracket, and a respective cutting puck coupled to a distal end of each of the plurality of elongate rods. The cutting pucks configured to remove a biscuit of excess material from the workpiece while being moved in the gripping direction.
