Abstract: A process and apparatus for producing metal balls from a cylindrical strand material, with two rolling jaws which are displaceable relative to one another and of which each forms a shaping groove which extends in a direction of displacement, wherein the jaws are located displaceably relative to one another such that U-grooves, which are located opposite one another on the opening side, form a shaping channel, a blank being rolled, as a result of displacement of the channel walls relative to one another, on its passage through said shaping channel.

Abstract: A rolling mill system associates an autonomous control unit with each piece of equipment in the rolling mill system. The autonomous control unit has a model of the particular piece of equipment, for example, of the rolling mill, a reheat furnace or a cooling bath, and data indicating constraints on the operation of the equipment. A metal shape to be produced is described as a set of machine independent steps, and the performance of these steps is bid upon by the autonomous control units according to the constraint models and internal goals. Bids having conflicting requirements may generate counterbids until a complete plan for the production of the product is generated.

Abstract: A pipe cutter having dual outer knives and a method of using the same is disclosed. The outer knives are mounted on knife positioners capable of swinging the outer knives into a pipe in an arc to overlap with a knife positioned inside the pipe. The method includes the step of simultaneously swinging the outer knives into a continuously rotating pipe in an arc having a rotational direction opposite the rotational direction of the pipe.

Abstract: A process for planishing under traction a thin metal strip in an installation including a planisher comprising at least one bending unit with two planishing sets and a multi-roller leveling assembly comprising two rows of rollers. The imbrication of the planishing sets and the multi-roller leveling assembly and two tension blocks, respectively, are adjusted upside and downside to obtain a prescribed elongation of the strip. Flatness faults in the planisher are corrected by adjusting the through-speeds and imbrication of the planishing sets, such that the prescribed elongation for planishing is substantially attained by the time the strip leaves the planisher.

Abstract: An apparatus for simultaneously cutting and notching a pipe includes an upper knife assembly having a pipe cutting knife and notch cutting knives with cutting edges adjacent a surface of the pipe and a lower knife assembly having a pipe cutting knife and notch cutting knives with cutting edges adjacent an opposite surface of the pipe. A method for cutting and notching a pipe includes stopping the axial and rotational movement of a pipe and moving the lower knife assembly into an overlapping relation with the upper knife assembly. The notch cutting knives are also moved into a cutting position and the axial and rotational pipe movement is resumed.

Abstract: A metal sheet bending machine for bending a metal sheet inserted between an upper bender and lower bender to a desired angle. While the metal sheet is being bent to the desired angle, a linear image of projected measuring light, which rotates with a change in the bending angle of the metal sheet, is formed by a measuring light source on an outer face of the bent metal sheet and sequentially photographed and stored. Based on the stored images, the bending angle of the metal sheet is calculated. Based on the result of the calculation, the positions of tile upper and/or lower benders are controlled whereby the metal sheet can be bent to the desired angle.

Abstract: A machine combines metal rod chamfering and stamping operations into a single machining operation. Cutting the chamfer on the end of the rod is accomplished by a rotating cutting tool affixed to a chuck which rotates with a spindle about an axis co-linear with the axis of the workpiece. Both the chuck and the spindle contain a hollow bore along their rotational axes. This bore holds a stamping rod which is free to move axially within the spindle. A stamping impact unit is located at the opposite end of the spindle which acts upon the opposite end of the stamping rod. At the desired moment within the chamfering operation, the stamping rod is hammered into the end face of the workpiece by the impact unit. The imprint end of the stamping rod functions as a mechanical stop to locate the depth the workpiece is inserted into a clamping collet.

Abstract: A machine for cutting and threading bicycle spokes (11) comprising a cradle (15) for receiving a spoke, a cutter mechanism (17) positioned to intersect and cut off the spoke at a predetermined point, and a thread rolling apparatus (56) positioned adjacent the cutter. By turning a handle (41) the cutter mechanism is actuated by an eccentric (54) and cam (32) to actuate a lever (24) and move a shear (20) past a stationary shear (19) and sever the spoke. Further turning of the handle causes a feed lever (66) to shift the spoke to a position to be contacted by a movable die (61) to complete the cutting and threading process.

Abstract: Flange forming drill apparatus for producing a flanged hole in a workpiece such as the side of a pipe or the like includes a body supporting a rotating drill rod and legs for supporting the body to move toward and away from the workpiece. A drill bit is provided at the end of the drill rod for drilling a hole upon movement of the body towards the workpiece along the support legs and a plurality of flange forming members are mounted on an end portion of the drill rod for movement between a retracted position while the hole is drilled and an outwardly projecting position for forming a flange around the edge of the hole when the body is moved away from the workpiece. An adjustment member on the drill rod is provided for moving the flange forming members between retracted and extended positions and brake bits are mounted on the legs for engagement by the adjustment member for extending the flange forming members when the hole is completed.

Abstract: Disclosed is a machine for chisel forming the teeth on parts of revolution, and in particular wheels of cigarette lighters or the like, comprising a programmer whose drum is rotated permanently by a first linkage engaged with the drive shaft of the machine, a spindle receiving and rotating the workpiece to be toothed, means for holding this workpiece during the forming of its teeth, a device for storing and presenting the workpieces, a system for imparting rotation to the spindle and a chisel-holder striking device comprising a chisel fixed on a back-and-forth moving device keeping the chisel engaged with the driving means which require it, upon the striking of each tooth, to describe an imposed path causing it to penetrate forcefully, under pressure, into the workpiece to form the hollow of the tooth by working up the material.
