Abstract: Disclosed is a method for cooling a coated wire including: preparing a water storage tank disposed between an extruder for coating a core wire with an insulating material and for feeding the coated wire forwardly, and a winder for winding the coated wire; and passing the coated wire before being wound through still water in the water storage tank thereby rapidly cooling the coated wire, the improvement comprising: preparing trough members disposed between the water storage tank and the extruder along the advance direction of the coated wire in such a manner as to cover the coated wire from the underside; and cooling the coated wire by water which is discharged to the trough members and is made to flow therein and thereafter passing the coated wire through the water storage tank. Using the above method, even in manufacture of an insulated wire having a coated outside diameter of 1 mm or less, it is possible to suppress the surface roughness of the coated wire in the degree of at least 1 .mu.m.

Abstract: A press working control method for controlling the press working operation of a press having a pressure cylinder for applying a working pressure to a workpiece, a press slide operatively connected to the pressure cylinder and carrying a movable die, a bed fixedly mounted with a fixed die, a plurality of control cylinders supporting the press slide in a level position during the press working operation, and a press control system for carrying out the press working control method. The press control system comprises a first pressure detector for detecting the operative pressure of the pressure cylinder, quick-response control valves each for regulating the height of the control cylinder, height detectors each for detecting the height of the control cylinder, second pressure detectors each for detecting the operative pressure of the control cylinder, servovalves each for detecting the operative pressure of the control cylinder, and a control unit including a computer for deciding manipulated variables for the height and operative pressure control of the control cylinders on the basis of data obtained by the detectors. The respective heights of the control cylinders are regulated individually so that the press slide is maintained in a level position during the press working operation, while the respective operative pressure of the control cylinders are regulated so that a desired working pressure is applied to the workpiece.

Abstract: A mold clamping device for an injection molding machine wherein a movable table which supports a movable mold is moved in directions approaching and moving away from a fixed table which supports a fixed mold to thereby bring the molds into open and closed states, and wherein mold clamping is effected in a closed state of the molds by mold clamping cylinders. The mold clamping device includes tie rods for guiding the movement of the movable table, the tie rods projecting upward from the fixed table and being each provided with an engaging groove such as threads or the like formed on the outer peripheral surface of its portion projecting from the movable table to the side opposite to the fixed table in the closed state of the molds; and split mold-like locking members capable of engaging with and disengaging from the tie rods each through each engaging groove in the closed state of the molds, the locking members being slidable in the axial direction of the tie rods. The mold clamping cylinders are disposed between the locking members and the movable table. Since the tie rods which receive the mold clamping reaction are so constructed as to also be employable as guide members for guiding the movement of the movable table, it is possible to attain a structural simplification and reduction in size in addition to advantage in terms of maintenance.
