摘要:
An apparatus for reclaiming metal cladding or the like from an elongated clad workpiece, with minimal or no damage to the workpiece, so that it can be reused. The apparatus includes an improved carriage-mounted shearing tool that is advanced or walked progressively along the workpiece and after making an initial separation of the cladding from the workpiece completes the separation by a unique peeling of the cladding from the workpiece. The apparatus may also be provided with an impact type tool for use in the decladding operation.

Apparatus for forming an array of elongate slots in the bore of a valve sleeve (1) where the slots are cut in the bore by an arcuately movable cutting tool (5) mounted on the apparatus and the movement of the cutting tool (5) to form the length and depth of each slot is under the control of a desmodromic cam (12, 13) and a variable offset between the pivotal axis (8) of the cutting tool (95) and the pivotal axis (10) of the followers (15, 16) contacting the cam (12, 13).

An angle adjusting mechanism or a linear axis of a processing machine is provided with a reciprocation device. A tool and a tool cutting mechanism are mounted on a moving part of the reciprocation device. A workpiece is processed by the tool based on a combination of the drive of the processing machine and the drive of the reciprocation device.
摘要:
Method and apparatus for fabricating a perforated film comprising the steps of pinching a film material, (3) between a cutter roll (1) with cutting edges (12) and a backing roll (2) to press the cutting edges (12) to the film material (3) and driving, to rotate least one of the cutter roll (1) and the backing roll (2), to form holes such as slits in a film material. The apparatus is decelerated by a stop command signal of an apparatus, detecting the speed of the apparatus attaining a predetermined small speed, generating an advance stop signal when the apparatus is approaching a stop a condition, and displacing the backing roll (2) so that the cutter roll is separated from the backing roll.

When a slide member mounted with a tool reciprocates on a guide member reach one end and the other end positions of the guide member, permanent magnets provided on the guide member and the permanent magnets provided on the slide member repel each other to give the guide member forces for reversing its moving direction. The guide member is provided to be movable with respect to a base and repulsive forces between permanent magnets provided on the base and permanent magnets provided on the guide member are used to retain an axial position of the guide member.
摘要:
Profiled workpieces are produced in a machine tool having a toolholder for at least one tool and work carrier for the workpieces, there being means for relative reciprocation of said toolholder and carrier. In the course of the reciprocatory movement the tool produces a profile on the workpiece in the direction of movement of the toolholder. The length of the profile in the stroke direction is greater than the length of the stroke movement. To produce the desired tool length, this is divided, in the direction of the relative movement between tool and workpiece, into at least two portions which are produced separately from one another.
