Abstract: In a burr removing method and apparatus of the present invention, a burr located at an edge of a steel piece is cut with a cutter by disposing the cutter such that the flank of the cutter is substantially in parallel with the surface of the steel piece on which the burr exists and the angle between the cutting edge of the cutter and the edge of the steel piece which the burr intersects is at least 45° and relatively moving the cutter toward the outside of the steel piece along the lengthwise direction of the burr; or by disposing the cutter such that the flank of the cutter is substantially in parallel with the surface of the steel piece on which the burr exists and the angle between the cutting edge of the cutter and the edge of the steel piece which the burr intersects is at least 90° and cutting the burr located at the edge of the steel piece by relatively moving the cutter perpendicularly to the lengthwise direction of the burr.

Abstract: A deburrer machine for cutting burrs (2), which consists out of a rotating deburring body (3) and travelling carriage (6) is foreseen for application especially on longitudinally cut slabs in flow. For deburring the deburring pistons (4) perform a rotary movement around the deburring body axis (21), whereby they approach to the cutting burr (2) from the workpiece side. Therefore the rotation axis is arranged in a way that the deburring pistons (4) turn below the lower workpiece surface outside the workpiece (1) after having finished the deburring procedure in order to lift again against this lower surface. Inside the deburring body (3) is placed a pressure chamber (18) which effects the lifting of the deburring pistons (4). Thereby the air contained in the lower piston guidance (12) is displaced and then the throttled air is led-off via bores in the lower part of the deburring piston (4) in order to dampen the piston movement.

Abstract: The invention shows a travelling deburrer for cutting burrs (2) developing when steel strands are subdivided by oxygen cutting. The deburrer achieves safe deburring with high deburring rates with the help of cost and space reducing designs regarding drive, control and tools, by increased deburring energy and by a more advantageous blade design.

Abstract: In this application for protection rights a new deburrer is presented, in which the deburring device working on a slab (1) or a billet (1), as a stationary design moves the work piece with an integrated pusher drive or includes a pusher drive when designed as a travelling device.

Abstract: A method for cutting openings in a sheet of thermoformed containers. The sheet of containers is indexed into a cutting assembly. The cutting assembly includes a shear plate having a plurality of openings formed therethrough, and having an upper surface which defines a cutting plane. A locating means including a plurality of anvils is raised so that the anvils enter the containers and raise the sheet toward the shear plate. The end portions of the containers are located within the openings of the shear plate, and a portion of the containers is positioned in the cutting plane. The cutting assembly includes a blade mounted on piston/cylinder assembly for sliding movement along the upper surface of the shear plate. The cylinder is actuated to move the blade along the cutting plane. The blade cuts off the portion of the containers and creates an opening in the containers.

Abstract: A deburring apparatus for cutting beards formed at edges of slabs as a result of torch cutting of strands during continuous steel casting operations is disclosed. The apparatus includes extendable pistons having deburring tools mounted thereon. The deburring tools are arranged such that rotation between adjacent tools is substantially prevented. Compressed air containing a lubricant is used to extend the pistons and cool the deburring tools.

Abstract: In a steel casting installation with double-acting and fast-acting mechanical burr removal machine or unit for burn burrs which are produced when the continuous casting is cut up thermochemically, travalling or stationary burr removal machines or units are provided for stationary or moving bloom blocks or billets, wherein a shearing beam arranged stationarily or displaceably beneath the bloom in the horizontal plane inclinedly relative to the burr line carries a guided shearing bar which is resiliently adjustable in respect of height at both ends, in one piece or comprising individual, spring-mounted portions, possibly with front and rear cutting edges, for pressing against the burr line horizontally or inclinedly in the vertical plane.

Abstract: A hydraulically-driven deburring shear assembly used to remove dross from the edges of a slab of steel that has been torch cut. The assembly comprises a table assembly, a pair of arms, and a knife assembly. Each arm is adapted to alternately act as a pinch roll and a pusher arm to effect the consecutive deburring of opposed edges of a slab of steel, as follows. After the slab of steel is placed on the table, one of the arms is lowered to rest on the slab and apply a downward pressure on the slab, and the other arm is lowered to come into contact with the leading edge of the slab. At the same time, the knife assembly is raised to the level of the table. The other arm then pushes the leading edge of the slab back over the knife assembly to shear the dross from the edge. Both arms are then raised, the knife assembly is lowered, and the slab is traversed in the forward direction.

Abstract: The machine removes burrs from slabs (1) issuing from a continuous casting plant and cut to length by an oxygen cutting. The machine is of the type having a rotor mounted horizontally in a frame and carrying on its periphery means for removing the burrs. The burr removing means are self-retractable hammers (8) whose head (10) describes an envelope which is rendered substantially tangent to the lower side of the slab (1) by means (40, 36) for moving the rotor (4) vertically in translation carried by the frame (21, 22). The rotor (4) is driven by a driving shaft (51) whose rotation is controlled in one direction or the other by a control device as a function of the detection (C1, C2, C3) of the passage of the head end or foot end of the slab.

Abstract: A knife support is part of the apparatus, and with a knife it passes by at the edge of the work piece which is to be deburred. The edge of the knife corresponds in its length at least to the length of the edge to be deburred. In order to be able to shear both the front end and the rear end of slabs with one and the same construction in a simple and sturdy way, the knife support is provided as a rocker arm which can be moved with a pivot drive. The swivel axis of the rocker arm can be directed about parallel to the edge of the work piece to be deburred.

Abstract: When a continuous cast slab is cut, such as by gas cutting, burrs tend to be caused at the cut edges. These burrs are removed by a plurality of edged cutting tools which are installed serially along the width of the slab to be treated. Each of the edged cutting tools may be selectively raised or tilted in the vertical direction or moved in the horizontal direction to substantially follow the warped or otherwise uneven surface on which the burrs are located. In this manner, substantially all of the burrs are exactly and completely removed.

Abstract: The flame-cut sheet metal elements to be deburred have a surface which lies substantially in a plane and have edge portions which are formed with sharp-edged metallic burrs extending generally in said plane and carry slag beads which protrude from said surface. Tool means are caused to perform a gyratory motion parallel to said plane and while performing said motion are engaged with said slag beads to break them off. Said tool means are caused to engage also said metallic burrs while performing a gyratory motion parallel to said plane, whereby said burrs are impact-deformed.
