A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a stop member movable along one of the X and Y axes and a clamping element for clamping the workpiece in the stop member for movement therewith. The clamping element is movable independently of its associated stop member as well as therewith, and one stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. In one embodiment, the clamping element is a claw or clamp in a fixed position on the stop member and which is automatically actuable to clamp the workpiece or to release the workpiece for guided movement thereby. In another, the clamp is slidably supported in the stop member for movement relative to a base element to provide clamped guiding movement for the workpiece and also can be locked in a position to fix the workpiece therefor. The machine tool also includes a computer control system for operating the motors which drive the guide assemblies and for operating the hydraulic mechanisms.

Apparatus and method for clamping and positioning workpiece in machine

A machine tool employs a workpiece guidance system comprising a pair of guide assemblies each including a first stop member movable along one of the X and Y axes and a clamping element a second stop member for clamping the workpiece against the first stop member for movement therewith. The second stop member element is movable independently of its associated first stop member as well as therewith, and each stop member will provide a guide surface for the workpiece as it is moved past it by the other guide assembly. The machine tool also includes a computer system control for operating the motors which drive the guide assemblies.

Stop mechanism, particularly for stampling machines

A machine tool installation enables the production of a variety of parts from a workpiece, and sorting of the parts so produced, on a fully automated basis. The machine tool has a numerical control system by which its cutting tool is caused to act upon the workpiece to selectively produce any of a number of different parts. The same control system is concurrently utilized to operate a sorting unit to position the designated one of several receptacles provided thereon to a point adjacent a common discharge location from the machine tool. The different parts produced are thereby segregated into substantially homogenous batches within the several receptacles provided.

Installation comprising automatic machine tooling and sorting apparatus

A bottom die provided with a cutting edge which is closed within itself used with stamping machines having a seat for the bottom die comprises a die body made up of at least two separate body parts adapted to be assembled together and forming an annular exterior die part with an internal die cutting edge. The body parts are separable along a parting line which is transverse to the die cutting edge. The body parts are held together by suitable means such as clamping screws.

There is disclosed a method and apparatus for the simultaneous machining of a stack of plate-like workpieces wherein the individual workpieces of the stack are initially assembled into a stack which is held in a manner which will not interfere with the subsequent machining operations by use of rivets or the like. The plate-like workpieces are mounted in the stack upon a support plate, and the machining operations are preferably so conducted as to penetrate through the lower most member of the stack and into the upper portion of the support plate. The machine tool is preferably one in which a series of stations for drilling, riveting, machining and then drilling out the rivets is provided. The tool may include means for automatically and precisely moving the stack between the several work stations. The method involves the preliminary assembly of the stack of plate-like workpieces upon the support plate and the initial clamping in that assembly until the elements of the stack are initially drilled and riveted to secure the elements of the stack in position relative to each other for the subsequent machining operations.

A machine is disclosed for working or machining flat workpieces which comprises, a frame, a flame cutter connected to the frame for directing a cutting flame or jet to one side of a workpiece which penetrates the workpiece, a mechanism for moving the workpiece past the jet and a cooling unit for receiving the flame after it has penetrated the workpiece. The cooling equipment includes an opening space for receiving the flame and a device for circulating coolant into the opening space so that the coolant can cool the flame and absorb particles, vapors and gases generated by the cutting operation.

Working machine with flame cutter and cooling unit

A machine tool construction, comprises, a support frame which has a bar portion extending in one direction, for example, a longitudinal direction, with a gear rack defined thereon, and with a carrier guide movable along said bar portion and having a drive motor for its movement with a pinion which is engaged on the rack to effect the motion. A work carrier is similarly mounted in the carrier guide for movement at right angles to the axis of the bar and it is driven by a separate drive motor driving through a pinion and a rack defined on the work carrier. At least one work holder is mounted for slidable movement along the work carrier and it may be locked to the work carrier against movement and transported by movement of the work carrier or it may be released from the work carrier. In addition, a locking device is provided for locking the work carrier in a fixed position and it may be carried either by the frame of the machine itself or by the carrier guide. The locking device includes a locking member which may be forced downwardly into a locking recess defined on each work holder, only when the work holder is located directly below the locking element. When the work holder is locked by the locking device, it may be released from the carrier, and the carrier may be moved to similarly transport another work holder into association with another locking device. Each work carrier includes clamping a clamp for clamping a workpiece.

A machine, particularly for stamping or nibbling, comprises a reciprocating tool drive having a plurality of tools connected to the drive for selective reciprocation thereof. The drive includes means for stopping at least one of the tools for exchange purposes and a tool-change member is mounted for movement alongside the tool drive and includes a member movable transversely to the reciprocation direction for engaging and removing a tool which is stopped or disconnected from the drive in order to effect an exchange with another tool without stopping the drives of these other tools. The machine also includes means for engaging and moving a workpiece transverse to the reciprocating direction. One or more tools may be exchanged by the use of a movable conveyor magazine which carries a plurality of tool sets along its length which are selectively positionable into alignment with a fluid-pressure operated piston and cylinder combination having means for engaging a tool which is aligned therewith and positioning it in a location for engagement by the reciprocating drive for the tools of the machine.
