Abstract:
An apparatus for cutting a single coil and adjusting distance thereof includes a longitudinal cut module and an adjustment module. The longitudinal cut module is adapted to cut the spiral coil at an end thereof according to an external diameter of the spiral coil, and to synchronously bend the spiral coil to prevent the spiral coil from departing from the document. The adjustment module synchronously adjusts a distance between the auxiliary shaft and the driving shaft, and a position of the longitudinal cut module. Therefore the winding bearing set and the longitudinal cut module synchronously meet spiral coil with the same diameter. By the aforementioned design, an objective of conveniently assembling spiral coil into the holes drilled on the document is achieved.
Abstract:
A high-toughness, quenched, oil-tempered wire for springs which is less likely to suffer a permanent set and is high in strength and toughness. The wire is made of a steel containing predetermined amounts of C, Si, Mn, Al and Ti, to which are selectively added predetermined amounts of V, Mo, W and Nb. After quenching and tempering, the content of retained austenite is 1-5 vol. %, and/or the number of carbides having a diameter of 0.05 .mu.m or more is 5 or less per .mu.m.sup.2 as viewed on a transmission electron microscope image.
Abstract:
A stop mechanism operative to stop a sprial lacing wire if the lacing wire encounters an obstacle as it is being wound in lacing fashion about juxtaposed end loops of coil springs in two adjacent coil spring rows, and after the lacing wire has completely laced together those two spring rows. A sensor functions to sense when the spiral lacing wire encounters an obstacle in its lacing path, the sensor incorporating a proximity switch that cooperates with a bowed guide element. The bowed guide element induces the lacing wire to pop out or bow away from the switch when the obstacle is encountered, activation of the switch causing the lacing wire to stop at once in its lacing path. A clamp device cooperates with a feeder switch to clamp the unlaced spiral lacing wire between its jaws when the feeder switch is activated by the lacing wire's lead end after the lacing wire has traversed the entire length of the adjacent rows.
Abstract:
A cooling conveyor arrangement for rolled wire or wire rod which has left a water cooler has a loop-forming device which deposits the wire in overlapping loops on an air-cooling conveyor. To obtain a shorter cooling path, which is desirable for high-grade steels to reduce the rate of cooling, the loops fall onto a conveyor portion and are carried by a conveyor portion to a coil-forming station where the loops are collected. To obtain a longer cooling path a removable conveyor portion is switched into place so that the loops are carried along a conveyor portion to an opening where they fall onto a conveyor portion. A conveyor portion is swung into alignment with the portion carrying the loops to feed the loops to the coil-forming station.
Abstract:
Apparatus for efficiently producing a wire fin tube for heat transfer which comprises fin-forming means for shaping a plurality of wires to a wavy shape, said fin-forming means including a pair of gears; means for guiding the wavy wires in an upstanding state including guide plates spaced apart a selected distance; means for feeding a revolving tube in a crossing direction, to the wavy wires so that the wires can be wound on the tube; means for controlling the operative speed relation of the fin forming means and the tube feeding means so that the wavy wires may be helically wound on the tube under a moderate tension so as to maintain the upstanding state and the same pitch as the distance of the guiding means; and means for welding the wire fins to the tube.
Abstract:
Apparatus for untwisting and stripping the ends of wires in a twisted pair comprise a first clamp which clamps the pair and a pair of cooperable insulation cutting blades which serve as a second clamp. Twisted pair is engaged by clamps and second clamp is rotated in untwisting direction. After untwisting, wires are pulled from second clamp to strip insulation.
Abstract:
A wire cropping tool which may be used for cropping wires to any required length after insertion of the wires through holes in a printed circuit board, consist of fixed and movable blades relatively movable upon actuation of a piston member reciprocable within a housing, the fixed blade having at the nose, a notch providing a shearing edge extending substantially normal to the plane of the fixed blade and an extension adjacent the shearing edge extending outwardly with respect thereto, and the movable blade being so fulcrummed with respect to the fixed blade as to allow a lug on the extremity of the movable blade and provided with a shearing edge to move through a curved path and substantially normal to the fixed blade thereby providing a positive cropping action. After cropping, the wires may be bent through any required angle and the construction of the tool allows the blades to be inserted into a stack of wires from above, i.e., with the pivotal axis of the blades substantially normal to the axis of the wires, such as to crop the wires thereby avoiding the difficulties of cropping wires by means of a tool inserted laterally or at an angle to the wires as heretofore.
Abstract:
A wire forming die for link fencing comprising a cylinder with a helical slot cut through it of which the inner edges of the slot are relieved to prevent damage to wire formed by the die.
