Abstract: A cold-weld burr removal system is disclosed according to various embodiments. The cold-weld burr removal system can include a clamping block having a clamping passage that extends along an alignment axis, and a removal block having a guide passage alignment axis centered about the alignment axis. The removal block can define a burr receiving chamber. The system also can include a cutting head insert having a cutting portion and a cutting passage. The cutting head insert can removably attach to the removal block and the cutting portion can protrude into the burr receiving chamber. The system can include a linear actuator that connects the clamping block to the removal block. The linear actuator can move the removal block in a direction along the alignment axis to increase a separation distance between the clamping block and the removal block when a linear actuation initiator initiates movement of the linear actuator.

Abstract: An apparatus is described for deburring with planing tools a metal strand cut to length by gas cutting, which planing tools are adjustably held each for themselves transversally to the metal strand in a support, and with a drive for the relative advancing movement of the planing tools relative to the metal strand which is cut to length. The annular support includes at least two sets of planing tools which are radially adjustable to the metal strand cut to length, which sets are arranged behind one another in the longitudinal direction of the metal strand cut to length and which are staggered against each other set by set.

Abstract: A post treatment process of a seamed belt for providing a smooth surface and substantially eliminating protrusions by using a planing blade, and a seamed belt that has undergone the post treatment.

Abstract: The bead trimmer is preferably applied in a production line for elements having longitudinal weld beads (21), where an element slides along a parallel direction to a longitudinal axis thereof (x), and comprises a tool-bearing turret (2) for removable fixing of a trimming tool (30), associated to a first slide (3) which is slidable along a horizontal direction (y) which is transversal with respect to the longitudinal axis (x) between an internal position, in which the tool (30) is aligned with the weld bead (21), and an external position, in which the tool (30) is not aligned with the weld bead (21). The first slide (3) is associated to a second slide (4) which is vertically slidable on a bearing structure (40) along a vertical direction (z) between a lowered position, in which the tool (30) is in contact with the weld bead (21), and a raised position, in which the tool (30) is distanced from the weld bead (21).

Abstract: The present invention provides a tool for bar peeling comprising a rotatable cutter head with circumferentially spaced toolholders each of which is provided with a U-shaped recess along one of its side surfaces. A wedge shaped element is longitudinally displaceable in the U-shaped recess so that an insert carried by the toolholder in subjected to radial adjustment upon a longitudinal displacement of said wedge shaped element.

Abstract: A method for shear forge bonding two or more metal parts having forging compatible compositions is comprised of the steps of sizing parts to be joined across a forged bond line, disposing those parts in forging dies configured to present them in a bonding-effective orientation, shearing surfaces, one on each of the metal parts, located proximately and opposite one another across a gap, under controlled conditions of temperature and atmosphere selected to prevent the formation of any bonding disruptive surface contamination on the sheared surfaces, and then finally forging those parts to close the gap and bring the sheared surfaces into contact under controlled conditions of temperature, pressure, atmosphere, and outer diameter constraint to yield a shear forged bond between the sheared surfaces.

Abstract: A method and apparatus for machining fragile workpieces of any material, by placing the workpiece upon a convex support, tensioning the workpiece into coextensive engagement over the support, and moving a cutting tool away from an anchored end of the workpiece to establish transverse and longitudinal configurations at exposed sides of the workpiece when removed from the support.

Abstract: A broaching method for finishing an outer peripheral surface of a resin layer of a resin-coated lobe-type rotor for a rotary fluid machine of a Roots type, which includes the steps of forming, with a leading grooving cutter, at least one chip-breaker groove in the outer peripheral surface of the resin layer, such that the chip-breaker groove extends in a broaching direction parallel to an axis of rotation of the rotor. The method further includes the steps of finishing at least a portion of the outer peripheral surface of the resin layer with a trailing finish cutter having a cutting edge contour corresponding to the portion of the outer peripheral surface of the resin layer, which is finished by the finish cutter after the chip-breaker groove is formed therein by the grooving cutter. A composite broach or formed broach having the grooving and finish cutters is fed such that the grooving cutter leads the finish cutter in the broaching direction.

Abstract: A wire shaving apparatus for shaving a periphery of wire, bar or rod stock, including structure defining a product flow path between an input and an output and a plurality of shaving stations spaced along said flow path for scrapingly engaging product conveyed through said structure. Each shaving station includes a pair of slide mechanisms, one slide mounting a releasable tool cartridge including a pair of cutting tools having associated cutting edges positioned at a predetermined angle, and another slide assembly mounting a product support cartridge including support rollers aligned with said cutting tools for supporting said product as it is being scraped. The slides are reciprocally moved between processing and retracted positions by a threaded drive shaft, the rotation of which is controlled by a servo controlled system. A clamping arrangement associated with each slide mechanism releasably clamps the tool and support cartridges allowing easy and speedy replacement.

Abstract: The arrangement comprises a body constructed in the form of a grip clamp arable from the vertical axis of a workpiece, and having two jaws coupled with each other in the upper portion thereof by a clamping cylinder. The arrangement further comprises cutters for deburring, and a mechanism for pressing said cutters to the workpiece surface. The cutters are mounted in the lower portion of the jaws so that cutting edges thereof form a profile of the workpiece cross-section. The cuttes disposed on the same jaw are pivotally connected with each other. The mechanism for pressing the cutters is constructed in the form of a system of hydraulic cylinders mounted on the jaws in symmetrical relationship relative to the vertical axis of the body. Said hydraulic cylinders are provided with rods operatively connected to corresponding cutters.

Abstract: A billet scalper including a die assembly with a scalping die, a pressing mechanism with a stem member in axial alignment with the scalping die for pressing a billet thereinto, and a chip ejector located around the circumference of the scalping die and movable axially back and forth beyond a free end face of the scalping die to remove chips therefrom. The die assembly including the scalping die is movable between a position at the center of the scalper and an outer receded position to permit easy maintenance and service of the die assembly including replacements and cleaning of scalping dies. In a preferred form, the scalper is constructed integrally with an extrusion press to perform the billet scalping operation in timed relation with the extruding operation to shorten the time of press cycle.

Abstract: An assembly for absorbing energy between first and second bodies subject to relative movement comprising a cutting ring on one of the bodies dimensioned to cut into and remove a layer from a cylindrical member on the other body. The ring has an annular cutting edge with an inner diameter smaller than the outer diameter of the cylinder member. The two bodies can be, for example, two tubes forming a coupling device between two railroad cars. The outer surface of the cylindrical member can have longitudinal grooves to promote small chip formation during the cutting operation, thereby reducing the chance of jamming.
