    Abstract: A swivel machine for wire processing has a coiler arranged between a cutting-off/insulation-stripping unit and a second swivel arm. The cut length of wire whose leading wire-end has been processed is coiled by a coiling disk of the coiler. After the leading wire-end of the cut length of wire has been processed, it is grasped by the coiler. A belt drive then advances the wire by the desired length of the cut length of wire, and the coiler coils the advanced wire simultaneously into a coil. After the coiling operation, a linearly movable stacker unit grasps the coil, and the coiling disk releases the coil. After the trailing wire-end has been processed, the stacker unit moves further in the wire-advance direction to the deposit. While the trailing wire-end is being processed, and while traveling to the deposit, the coil is provided with a bind.

  • Patent number: 7310984
    Abstract: A forming apparatus (50) includes a roll former (51) operative to roll form a metal strip (100) to form a profiled metal section (10) of generally C section profile including a pan (12) and a pair of upstanding edge margins (14 and 16). The section profile incorporates a longitudinal precamber which is introduced by the forming apparatus by incorporating a prestretching apparatus (52) upstream from the roll former (51), and a bending apparatus (53) located downstream of the roll former (51). The prestretching apparatus differentially stretches the metal strip (100) in its longitudinal direction so as to form portions (101, 102), which are more elongated than a laterally adjacent portion (103) of the strip (100). The differential stretching compensates for longitudinal shortening of the metal strip in forming the profiled section in the roll former (51). The bending apparatus (53) uses a (3) point bending process and includes a reaction stage (60), a fulcrum stage (61), and an action stage (62).

An unmagnetized magnetic strip is fed into the trolley of a magnetizing fixture, clamped stretched, and magnetized by a coil. The newly magnetized strip is then cut and fed into a trimming fixture. As the magnetized strip goes through the trimming fixture, it runs over a hall effect sensor which determines where a center of a pair of poles is located. Based on where a pair of poles is located the cutting blade of the trimming fixture is activated and a magnetic strip that can be turned into a speed ring is created.

  • Patent number: 4811587
    Abstract: An apparatus for making a panel, preferably a panel having a base and two sidewalls extending from opposite sides of the base and having lateral flanges. The apparatus includes a frame having a series of sets of forming rollers for forming flat sheet metal into the panel. A partially formed panel rests on a pair of spaced base dies, with the sidewalls supported by two pairs of spaced support dies.

  • Patent number: 4779438
    Abstract: A coil spring making machine wherein the advancing rolls for the wire are driven intermittently by a transmission which receives motion from a timing shaft through the medium of a reciprocable input element and two one-way clutches so simultaneously that the rolls rotate in opposite directions (one clockwise, the other counter clockwise). The knife which severs the wire at intervals so as to separate successive coil springs is driven by the timing shaft through the medium of a chain transmission and a link which causes the knife to travel along an endless circular path and to sever the wire while the advancing rolls are at, or close to, a standstill.

  • Patent number: 4655067
    Abstract: A method and apparatus for cutting predetermined lengths of panels from a continuous strip of flexible material and for forming the lengths of panel members to have a preselected panel profile. The strip is reel fed to a first strip driving station which drives the strip through a shearing station, over a hump table, to a second strip driving station and through a strip forming station. In sequence, the second strip driving station brakes the leading portion of the strip to effect a strip hump over the hump table, which is detected by a protoelectric sensor for hump height and signals the first strip driving station to vary its feed rate to maintain the hump; the second driving station is then signaled to commence driving the lead portion of the strip to the strip forming station.

    Abstract: A method of continuously forming edgewise wound cores. A continuous strip of ferromagnetic material is fed to a winding station and through a means operable generally for severing the continuous strip, and the continuous formation of the edgewise wound cores is effected at the winding station from the continuous strip fed thereto. The thickness of the continuous strip is measured along the length of the continuous strip fed to the winding station, and the thickness measurements are summed. The summation of the thickness measurements are compared with a preselected value corresponding to a predetermined stack height for each of the edgewise wound cores formed at the winding station, and the severing means is operated to sever the continuous strip at least generally when the summation of the thickness measurements attains the preselected value thereby to terminate the formation of respective ones of the edgewise wound cores at the winding station.

  • Patent number: 4549422
    Abstract: A roll (10) of metal lagging is loaded onto a loading rack (14). One end of lagging (8) is drawn upwardly and away from roll (10) by a feed drive roller (38) paired with a pressure roller (36). Before it reaches these rollers (36, 38), lagging (8) is pulled upwardly between a guide roller (28) and a pressure roller (26). The axis of roller (26) is slightly below the axis of roller (28). Lagging (8) is drawn between rollers (26, 28) and around roller (28) to drive roller (38). Drive roller (38) moves lagging (8) past a cutting station into engagement with two drive rollers (86, 88) of a curling mechanism (84). When a predetermined amount of lagging (8) has passed the cutting station, drive motor (104) stops and a movable blade (46) moves downwardly past a stationary blade (48) to cut lagging (8). A pressure foot (54 ) moves downwardly with blade (46) and in cooperation with a guide block (58) forms a bend (6) on lagging (8) just before it is cut.

  • Patent number: 4528831
    Abstract: A machine for coiling wire to form any one of a number of different size, type and configuration of coil spring and comprising a machine frame in which is mounted a driveshaft, intermediate shaft, camshaft, and feed roller shafts. At a work station of the machine appropriate coiling dies are supported along with one or more cutters mounted adjacent thereto. The wire is fed to the work station via a pair of feed rollers driven at variable speed, preferably by an elliptical gear drive, wherein the feed speed is at a maximum during coiling and decreases to a minimum feed speed for cutting. Wire feed is synchronously interrupted at cutting by means of a cam arrangement that briefly disengaged the feed rollers. This variable speed drive enables a high duty cycle of operation and also enables start up (feed rollers engaging) at reduced speed so as to minimize wire distortion.
