ARCHITECTURAL PANEL AND METHOD FOR MANUFACTURING THE SAME
A method for manufacturing an architectural panel and an architectural panel made by the method. The architectural panel may be formed from metal, and the method may start with the processing of a flat metal sheet. The method may include punching holes in a particular pattern into the flat metal sheet, bending the flat metal sheet into a particular shape to form a panel that can be hung from an overhead grid or the like, and printing a desired printing pattern onto the panel. The method may also include a step of coating the panel with a powder coating or a liquid-applied paint finish prior to the printing step. The coating step may occur after the punching step and before the printing step.
METHOD AND DEVICE FOR PRODUCING TEAR-OPEN LIDS
A method for manufacturing a tear-off lid (27). A lid blank (9) is punched with a punching tool (1, 5) having a die (6) and a cutting punch (2, 3) to form a lid ring (8) with a central removal opening (17) surrounded by a sealing flange (18). The edge of the removal opening (17) is then formed by drawing to a collar (20) projecting from the sealing flange (18) on the intended inside of the lid (underside), the collar (20) is rolled up at its free end and a tear-off foil (24) is sealed or glued onto the sealing flange (18) on the intended outside of the lid (upper side).
In accordance with the invention, the die (6) is arranged on the inner side (bottom) of the lid and the cutting punch (2, 3) is moved into the die (6) from the outer side (top) of the lid while punching out a punched pad (16) and the punched pad (16) is conveyed by compressed air through the die (6) to a conveyor (33) by means of which it is removed from the tool area.
It has been shown that by this measure the known and established processes and devices for the production of tear-off lids can be modified with very little effort in such a way that during the punching of the lid blank (9) the punching or cutting pad is produced on the intended inner side (underside) of the produced lid ring (8), which is desirable when producing lids with “re-verse curl”.
Method for cutting a groove-shaped recess into a workpiece
With a method for cutting a groove-shaped recess in a workpiece, a cutting tool for a machine tool is provided on a workpiece. The cutting tool is displaced into a cutting position, in which the cutting tool is in engagement with the workpiece. The cutting tool in engagement with the workpiece is displaced relative to the workpiece for cutting the groove-shaped recess. Upon cutting, a chip is produced with a predetermined maximum chip length that is less than a total length of the recess to be produced.
CONTINUOUS PUNCHING METHOD
A continuous punching method comprises: providing a sheet material, applying a first punching process of a first punch station to the sheet material, and applying a second punching process of a second punch station to the sheet material. The first punching process includes: adjusting a punching depth of a punch blade of the first punch station to determine a lateral length to be punched out by the punch blade, and forming two longitudinally spaced apart first punched slits on the sheet material through the punch blade. The second punching process includes: adjusting lateral positions of two punch blocks of the second punch station, and forming two laterally spaced apart second punched areas on the sheet material through the punch blocks. The two first punched slits and the two second punched areas communicate with each other to form a contour of a combined cut-out.
Multi-dimple orifice disc for a fluid injector, and methods for constructing and utilizing same
A fluid injector for injecting fluid is disclosed, including a body; a fluid passageway defined in the body and extending from an inlet to an outlet of the fluid injector; a valve seat disposed internally of the body and forming part of the passageway; a valve element that is selectively reciprocated relative to the valve seat to close and open the passageway to fluid flow by seating and unseating the valve element on and from the valve seat, respectively; and an orifice disc disposed in the passageway downstream of the valve seat in a direction of the fluid flow through the fluid injector, the orifice disc including a plurality of dimples and a plurality of orifices defined through the orifice disc, each dimple including at least one orifice located thereon and each dimple having an asymmetrical cross-section.
Machining planar workpieces
A machine for machining, such as cutting and/or forming, planar workpieces has an upper tool and a lower tool that are movable toward each other to machine a workpiece arranged therebetween. The upper tool includes at least one cutting tool having at least one cutting edge and a clamping shaft. The lower tool includes a main body having a support surface for the workpiece. The support surface has an opening associated with an inner counter cutting edge. The lower tool has a positioning axis and at least one outer counter cutting edge provided outside of the opening and associated with the support surface. The outer counter cutting edge is aligned with an outer face of the support surface. A distance of the outer counter cutting edge from the position axis and a distance of the inner counter cutting edge from the position axis deviate from each other.
Processing Unit and Machine Tool for the Punching Processing of Workpieces
A processing unit of a machine tool for the punching processing of workpieces, in particular metal sheets, has a punching tool carrier configured to receive a punching tool and a stripper carrier for a stripper. The punching tool carrier can be moved by a punch drive along a stroke axis by a transverse drive element being driven by a punch drive motor relative to the punching tool carrier with a transverse drive movement along a transverse movement axis which extends in the transverse direction of the stroke axis. The stripper carrier can be moved along the stroke axis by a stripper drive, and the transverse drive element of the punch drive during the transverse drive movement can be moved relative to the stripper carrier along the transverse movement axis and the punching tool carrier and the stripper carrier can be moved relative to each other along the stroke axis.
COMPOSITE WORKING MACHINE
A press frame includes a lower press frame, an upper press frame that supports a press mechanism, and a vertical press frame. A laser frame includes a lower laser frame, an upper laser frame that supports a laser mechanism, and a vertical laser frame. A transport space for a workpiece in the press frame and a transport space for the workpiece in the laser frame communicate with each other, the transportation in the spaces being performed by a transporter. The upper laser frame includes a joint extending from the vertical laser frame toward the upper press frame side while being spaced from the upper press frame, and that switches between a connected state where the upper press frame and an end of the upper laser frame are connected and a separated state where the connection therebetween is released.
TOOL AND METHOD FOR PROCESSING PLATE-SHAPED WORKPIECES, IN PARTICULAR METAL SHEETS
A tool and method for processing plate-shaped workpieces, such as metal sheets. An upper tool and a lower tool are moved toward one another with a workpiece arranged in between. The upper tool carries a processing tool on a main body opposite a clamping shank. The lower tool has a main body and bearing surface for the workpiece with an opening in the bearing surface. The processing tool of the upper tool has a bending edge and the main body of the lower tool has a counterpart bending edge which is positioned in the opening of the bearing surface. The bearing surface being displaceable relative to the counterpart bending edge such that the counterpart bending edge projects from the opening in the bearing surface.
