摘要:
An apparatus for cutting off concrete, wooden, and/or metal piles, casing, conductor pipe and other metal tubulars, uses a metal frame and a metal blade linearly moveable within the frame, the blade being hydraulically and/or pneumatically driven to puncture and then slice and split through the metal being cut off, the cutting surface of the blade having a removable, centralized puncture point located essentially at the projected intersection between two concave cutting surfaces.

A cutting apparatus is disclosed and which includes a cutter knife which is reciprocally moveable along a path of travel, a track member mounted adjacent to the cutter knife, and which mechanically cooperates with the cutter knife so as to define, at least in part, a first non-cutting position, and the second, cutting position for the cutter knife, and a magnet mounted on the track member and which releasably magnetically restrains the cutter knife when the cutter knife is in either of the first non-cutting position, or the second, cutting position.

A method, and an apparatus, for operating a hydraulic shearing machine. For cutting a shearing-movement of at least one shear blade which is curved, starting from a starting-position under application of an overall actuating-force and for resetting of the shear blades which were moved for cutting to their starting-position after accomplishment of the shearing-movement, a reset-movement under application of an overall reset-force. The shearing-movement and the reset-movement are accomplished by a hydraulic actuating-mechanism comprising hydraulic cylinders, wherein the overall actuating-force and the overall reset-force being applied to the moved shear blades by at least one hydraulic cylinder of the actuating-mechanism. The magnitude of the overall actuating-force is adjustable by switching one or several hydraulic cylinders of the actuating-mechanism in and out of operation-mode. The method proposes that the positions of the curved shear blade are controlled by a control system by regulating the flow of hydraulic fluid to the hydraulic cylinders according to setpoints for a shear blade position versus time function and the overall actuating-force and overall reset-force requirements.

The powered pipe cutter and the pipe flaring tool both have a piston slidably mounted in a cylinder. The cylinder has a top end closed by a top end plug. A crimped cartridge bore in the top end plug communicates with a gas expansion chamber. A bolt and firing pin assembly are attached to the cylinder top end. The pipe cutter includes a shear housing with a pipe passage connected to the rod end of the cylinder. A shear plate is connected to the piston and moves with the piston to shear pipes. The pipe flaring tool includes a pipe clamp assembly with a pipe passage and a female flaring surface connected to the cylinder rod end. A male flaring surface on the piston cooperates with the female flaring surface to flare pipe ends.

The invention concerns a device for die-cutting a stack of sheet-like materials, particularly labels, whereby the stack is pressed into the die-cutter blade by a relative movement of a punching ram and a hollow cylindrical die-cutter blade.For a device such as this, it is proposed that the die-cutter blade 18 is adjustably held in a frame 16, and the frame 16 is accommodated by a receiving apparatus 13 which is mounted in a punch platen 12 and is adjustable relative to it, whereby the frame 16 can be slid in a plane parallel to the punch platen 12, in particular is adjustable in the direction of two major axes that are essentially arranged perpendicular to one another, and can also be tilted out of the plane.Such a device allows for precise orientation of the die-cutter blade relative to the stack to be punched.

A method for cutting to length a strip-shaped profiled member of unvulcanized rubber material by a cutting edge includes the step of providing a speed between the cutting edge and the profiled member to be cut of at least 2.5 m/s during the cutting action. The device for carrying out the method includes a carriage and a tool with a cutting edge fastened to the carriage. The carriage has an acceleration path, defined between a rest position of the carriage and a side of the profiled member facing the carriage, of between 0.2 and 1 m. The carriage has a deceleration path, defined between an oppositely arranged side of the profiled member and an end position of the carriage, of at least 0.1 m.

A slitting and transporting roller of the described type for sheets of material is suitable particularly as a mating roller in an apparatus for winding up sheets of film, paper and similar materials coming in continuously. In the inner cavity of the roller, a separator is inserted, which forms with the periphery of the roller the boundary at least one pressure space which extends essentially axially over the whole axial length of the roller and is in contact over penetrating boreholes in the roller sheath with the surroundings. Outside of the region of the penetrating boreholes the periphery of the roller additionally is provided with a penetrating slot, which extends, in turn, essentially over the whole axial length of the roller, for a separating slitter supported in the inner cavity of the roller.
摘要:
An apparatus and method for removing a plurality of printed labels configured as paper sheet portions from a plurality of stacked pressing sheets, the labels being partially precut and arranged in a predetermined pattern in the pressing sheets, including a die plate having a plurality of openings formed therein in a predetermined pattern corresponding to the pattern of the labels in the pressing sheets. The labels are pressed from the pressing sheets through the openings by a plurality of press members which are arranged in a predetermined pattern corresponding to the patterns of both the labels and the die openings, and project from a vertically movable press plate. As the labels are pressed from the master sheets, the die plate openings help to maintain the labels in aligned stacks.

A method for controlling punch press noise in which the noise level produced is monitored by a detector and the press ram velocity is modified in real time to keep the noise level within preset limits. A time weighted average noise level is also controlled by varying the ram velocity for punching operations over a period of operation to maintain a projected time weighted average within a preset limit.
