Abstract:
In the present invention, in cutting the top and bottom surfaces of a hot-rolled sheet by the rotation of milling cutters holding the sheet therebetween in the thickness direction of the sheet in the running process of the hot-rolled sheet, the cutting resistance determined by the cutting conditions including the type of hot-rolled sheet, the temperature in cutting, and the cut depth is controlled by the adjustment of cut depth, and cutting is performed by making the tension produced on the hot-rolled sheet by the cutting resistance lower than the breaking strength of the joint portion to prevent the breakage of hot-rolled sheet.
Abstract:
The invention provides a filtration apparatus for filtering and regenerating a machining fluid. The filtration apparatus includes a dirty tank for receiving the machining fluid and a clean tank fluidly connected to the dirty tank. A filter is provided between the dirty and the clean tanks for filtering the machining fluid which flows from the dirty tank into the clean tank. A conveyer mechanism is provided in the dirty tank for conveying the sediment of particles separated from the machining fluid in the dirty tank. A filter cleaning device are provided for cleaning the filter. The filter cleaning device includes a nozzle bar which is provided in the clean tank for rotation within a plane parallel to the filter means. The nozzle bar directs the machining fluid in the clean tank onto the filter means to blow the particles off the filter means into the dirty tank.
Abstract:
A device for holding a nozzle of a hose of a vacuum source to a drill press. The device includes a first portion for attaching to the drill press and a second portion operatively connected to the first portion for holding the nozzle of the hose of the vacuum source in a predetermined orientation to a work piece. The first portion is T-shaped and includes a first tube for attaching to the drill press and a second tube that extends perpendicularly-outwardly from the first tube thereof and which is internally threaded and has a pair of throughslots that extend axially therealong. The second portion is substantially T-shaped and includes a tube for holding the nozzle of the hose of the vacuum source and an appendage that extends perpendicularly-outwardly from the tube thereof. The appendage is externally threaded and is threadably received in the second tube of the first portion so as to allow the tube of the second portion to be rotated relative to the first tube of the first portion for allowing the nozzle of the hose of the vacuum source to be orientated to the work piece.
Abstract:
Chip enclosure (150) wherein the interior portion comprises a primary suction port (152) and a secondary suction port (154). Both primary suction port and secondary suction port are connected via a short neck portion (155) to outlet (156) that is in communication with a source of vacuum. The bulk of chips formed as a result of machining are captured by the primary suction port (152) while any remaining chips fall to the lowest location of the chip enclosure (150) where they are drawn in to the secondary suction port (154).
Abstract:
A manual machine tool (10) includes a vacuum device for dust removal (19) situated in its housing (12) and a blow-out connection (20) installed after this. A dust collection box (21), particulaily self-contained, can be attached in detachable fashion to the blow-out connection (20) via its blow-in connection (22). The dust collection box (21) is airtight on all but two sides and has air-exit holes (40) on the top side (36) and a dustproof filter element (48)—especially a fluted filter—on the inside. The dust collection box is particularly secure against the unintentional escape of dust after the dust collection box is detached from the associated manual machine tool because a pair of sealing lips (500) arranged as a separate part is provided inside the blow-in connection (22), which pair of sealing lips (500) is connected as a single part with closing flaps (520, 520) projecting into the interior of the dust collection box (210).
Abstract:
The invention relative to a device for machining workpieces comprising: a chip removing, rotating tool (2) configured substantially as a hollow body including at least one cutter (4), a portion of the tool adjoining the cutter (4) being penetrated by a chip receiving opening (6) for communicating chips into a tool cavity; and an exhaust means including a stationary exhaust housing (10) configured substantially as a hollow body communicating with the cavity (8) at least in part and in connection with at least one exhaust air source; the communicating portion of the exhaust housing (10) comprising in the region of the cutter (4) a chip communicating window (26) porting into an exhaust passage (36) of the exhaust housing (10); and the exhaust passage comprising in an exhaust passage section upstream of the chip communicating window (26), relative to the exhaust direction, at least one auxiliary air infeed opening. The invention relates furthermore to a method for machining workpieces by means of one such device.
Abstract:
In an apparatus for extracting chips from slots cut into a substrate, a cutter having a cutting implement is mounted thereon and is adapted to cut slots into the substrate. At least one injector is positioned proximate to the cutting implement, and includes a nozzle having a nozzle tip directed at the slots such that during operation a current of gas is directed into the slots to loosen any substrate chips therefrom which were generated during the cutting operation. A vacuum apparatus is positioned proximate to the cutting apparatus for capturing and removing the substrate chips loosened by the injector.
Abstract:
A tool (1) for centering and gripping a part (10) to be secured, having a through passage (10a) and sized for the tool (1), includes a guide member (3), at least one gripping element (4) mounted on the guide member (3) and a body (2) enclosing the drive and guide element of the tool (1). The guide member is mounted on a securement support having a support part (6) provided with a passage (7). The guide member (3) projects at the free end of the support part (6), the free end constituting the reference surface or support surface (9) of the part (10) to be secured whilst the body (2) of the tool (1) is gripped against a surface of the support opposite the support part (6).
Abstract:
With high speed machine tools, there is a desire to dampen vibrations and to retain the damper mass in proper position. The present invention relates to a tuned damped absorber support providing simultaneous energy dissipation in both horizontal and vertical directions which also provides for proper mass position retention. The tuned damped absorber assembly is attached directly or indirectly to a machine component requiring damping. Both single damper mass and double damper mass configurations are shown. With a double damper mass, the system can be tuned to two different frequencies. Therefore, the double damper mass provides for optimization in both a vertical and a horizontal direction.
Abstract:
A chip treatment device 100 includes a box-shaped housing 110, and an upper surface panel 112 of the housing is connected to a sloped portion 114. The interiors of the housing 110 is divided into upper and lower areas by a partition panel 130, and to the areas are provided a first cutting fluid bath 150 and a second cutting fluid bath 160. Chains 240 stretched between driving sprockets 210 and chain guide units 230 are equipped with scraper units 250 moving in the direction of the arrow. The chips coming in from an entrance opening 180 is separated from cutting fluid while being conveyed on the separation panel 130. First and second filter units 170, 300 filter said cutting fluid.
