Definitions

  • a method of treating wire after it is coiled in a heated state upon leaving a rolling mill and is treated by cooling as it is moved downwardly in a cooling shaft after the coils are formed comprises accumulating coils of wire adjacent the bottom of the cooling shaft until a predetermined amount is collected in a coil stack. Thereafter the supports for the coil stacks are moved away to permit the accumulated coil stack to drop downwardly to a collection base.
  • the supports are returned to their original position and a few coils are permitted to accumulate in a new stack while maintaining the wire connection between the new stack and the stack which has been dropped downwardly. Thereafter the connection coil of wire between the two stacks is cut away.
  • the method facilitates the maintenance of the newly formed coils in a stack orientation without displacement.
  • the cutting of the wire connection between each successively formed coiled stack is made only after a few coils of the newly formed stack are rst accumulated on a support.
  • a device for carrying out the method includes a support made up of two supporting elements which are movable toward each other adjacent the bottom of the vertical shaft in order to support the coils for stack accumulation.
  • the supporting elements are moved apart to drop each stack after a sucient number of coils has accumulated.
  • the supporting elements are moved together again, they separate one coil stack from another and permit accumulation of a new coil stack thereon while the connection between the successive stacks is maintained.
  • a cutting knife and a sweep arm Directly below the movable members is a cutting knife and a sweep arm which directs the connecting coil of wire between the old and the new stacks into association with the cutting knife.
  • the invention relates in general to a method and apparatus for treating rolled wires coming directly from a rolling mill and in particular to a new and useful device for receiving and holding successively fed coils of such wires with means associated therewith for cutting the wire to separate the individual coils and also to improved means for forming the peripheries of the stacks of the wires which are fed from a cooling shaft in which the wire coils are formed and treated.
  • Wires which are formed in a rolling mill are directed from the rolling mill into a vertical annular shaft in which the wires are formed into a coil form and deposited on means for delivering the successive coils past a station traversed by cooling air.
  • the present invention provides means for channeling the coils of wire after they are delivered downwardly from the cooling shaft.
  • the cooling shaft there is provided below the cooling shaft two platform members which are movable on a trackway toward and away from each other and which provide a support when moved together for a coiled stack of wire.
  • a member for engaging the length of wire which extends between a coil resting on the cable platform and the one fed downwardly onto a centering mandrel therebelow. The member catches the free length between the coils at whatever location it may be in and moves it into association with one or another of a plurality of cutting elements which are arranged therebeneath.
  • a feature of the construction is that without affecting the position of the accumulated coil of wire on the platform, it is possible to withdraw the platform elements outwardly at which time there occur two equal and opposite forces which prevent the coil from moving sideways. During this movement, the separation of the next coil is achieved when the platforms are moved backwardly to begin the accumulation of a new coil stack.
  • the catching elements arranged below the platform will sweep through an arc to engage the connecting length of wire between successive coils (that is, the one accumulating on the platform elements and the one which has just been directed downwardly onto a collecting platform over and around a centering mandrel) and direct it toward means for severing the coil and the connecting length.
  • the centering mandrel is advantageously mounted so that it may be withdrawn downwardly through an opening in the collecting bottom or platform so that the coil may be pushed to a wire coil tying machine after it is formed around the mandrel.
  • the collecting platform may be made in the form of a conveyor belt ⁇ for advancing the coil to the next station.
  • a vertical cylindrical shaft having an upper aperture consisting of a rotation ring with guide means for directing the wire turns.
  • the guide means are angled inwardly and downwardly and provide a means for insuring the uniform stacking of the wire turns so that their outermost portions will lie in a circular ring. In this manner the loops of wire are stacked in uniform layers of cylindrical cross section suitable for being lowered onto a collecting bottom and centered over a centering mandrel.
  • the guide means includes one or more arms which are rigidly fastened to the rotating ring and which press against the periphery of the wire turns towards and against the diametrically opposite smooth shaft wall of the cylindrical member.
  • the guiding arms each include an oblique portion extending inwardly for guiding the turns downwardly gradually and a straight portion which presses against the periphery of the four coils in a circular.
  • the circumferential speed of the arm is regulated according to the number of turns produced per unit of time. The spacing in a horizontal plane of a wire turn can be inuenced by the speed of the rotation of the ar-m.
  • a further characteristic of the invention is the drive for the movable platform elements upon which the coils are deposited after they leave the cooling shaft.
  • the platform elements are mounted so that they may be rolled backwardly and forwardly along a trackway and the movement is controlled by a fluid piston engine having piston rod elements connected separately to the individual platform members.
  • the weight of the coils upon the platforms permits the easy withdrawal of the two platform elements outwardly to permit the coils to drop downwardly. Only the empty weight of the platform elements must be moved upon closing.
  • the actuation of the fluid piston engine is accomplished by switch means as a function of the wire weight collected on the bottom platform elements.
  • Such switch means are adjustable in stages for minimum weights of the coil with the beginnings adapted to the large coil diameters and wire diameters.
  • a further feature of the invention is the arrangement of the catcher elements which are designed as two armed levers which are mounted so that they will pivot through arcs to engage a collecting length of wire between two successive coils regardless of its location.
  • the location of the connecting length of wire of the coil will vary so that the arm on one side may in some instances engage the connecting wire and direct it to a cutter arm on the adjacent side, or the arm on the opposite side may move the connecting length to a cutter arranged on its side.
  • the levers may be arranged in different parallel planes so that overlapping movements are possible. In this manner one lever is certain to seize the loop or to pass it to the other lever.
  • the platform members may themselves be designed as catcher elements to insure that the connecting link of wire cable is directed into association with a cutting element. When separate levers are employed as catchers they are advantageously movable along with the movement of the platform members.
  • a further characteristic is the provision of shears which are mounted for association with each catcher or lever arm member for guiding the connecting length of cable into association with the cutter.
  • the shears are such that their mass need not be either accelerated or retarded.
  • the shears are advantageously secured to the collecting shaft circumference at diametrically opposite locations. They may be controlled by limit switches arranged in the guide track for the platform members so that they will be actuated to cut off the connecting length of wire for example when the platform members are closed.
  • a further object of the invention is to provide a ring guiding member for use in association with a movable platform element on which successively formed groups of coiled wire are positioned and which includes a rotating guide member for insuring a cylindrical formation of each of the coils as they are deposited.
  • a further object of the invention is to provide a method of treating wire which is formed directly from a rolling mill and then cooled in a cooling tower comprising directing the wire directly from the cooling tower onto a receiving platform for forming a coiled stack of a predetermined number of coils, cutting the connecting wire between the formed coil and the previously formed coil and dropping the newly formed coil downwardly onto a collecting bottom.
  • a further object of the invention is to provide a wire coil treating and forming device which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a vertical axial sectional view of a device for cutting newly formed coils of wire into stacks having a predetermined number of coils constructed in accordance with the invention.
  • FIG. 2 is a section taken on the line 2-2 of FIG. l;
  • FIG. 3 is a section taken along the line 3-3 of FIG. l;
  • FIG. 4 is a view similar to FIG. 3 of another embodiment of the device.
  • FIG. 5 is a section taken along the line 5-5 of FIG. 4;
  • the invention embodied therein as indicated in FIGS. 1 3 comprises a device for forming and separating groups of coiled stacks of wires which are delivered or which fall downwardly from a tower or shaft 10 in which the newly formed coils are cooled.
  • the wire turns 51 are dropped so that they are collected over a shaft bottom or platform generally designated 22.
  • the platform in accordance with the invention includes two platform elements or platform halves 22a and 22b having rollers 21 which are guided for lateral movement on a trackway or guide 20.
  • the movement of the platform elements 22a and 22b is controlled by a fluid pressure-operated piston engine 52 having a connecting rod 52a connected through a crank arm 53a to a double lever 53.
  • the collecting bottom 23 in the embodiment illustrated may advantageously comprise a platform or wall member having an opening through which the centering mandrel 24 may be moved in vertical directions.
  • the mandrel may be extended to the position indicated in FIG. 1 in order to provide a centering element for stacking a coiled -bundle 54 therearound.
  • the mandrel 24 is then lowered into the platform or bottom wall 23 to free the stack 54 so that it can be moved to a following treatment station.
  • the mandrel may comprise a reel which may be rotated.
  • 'Ihe arms 55 are advantageously actuated by movement of the platforms 22a and 22b so that they will move the connecting length 51a into association with the cutter for severing the same when the two platform parts 22a and 22b are moved together. They are returned to their starting position after their platform bottom halves 22a and 22b have been returned together to a closed position.
  • the mouth ring assembly including the rim 62, the plate 62a and the mouth 62b is rotated to rotate guide means comprising an arm 64 therewith.
  • the arm 64 includes an oblique portion 64a and a vertical portion 64b which provide the double function of guiding the wire downwardly into a stack and then insuring that it is formed into a cylindrical formation.
  • the rotation of the vertical bar 64b around with the mouth ring causes the wires to form into an even cylinder so that when the wire turns are deposited on the plat form parts 22a and 22b they describe cyclic curves which always lie with their greatest diameters on the inside diameter of the shaft and with their smallest diameters on the circle described by the arm 64.
  • a suicient number of windings have collected on the shaft bottom portions 22a and 22b they move the part to permit the coil to drop downwardly over the mandrel 24 and to effect the cutting of the connecting cable 51a which is between the newly formed stack and the next stack to be formed on the platform parts 22a and 22b when they are moved together.
  • a device according to claim 1 wherein said cutting means includes a catching member, and means mounting said catching member for movement through an arc below said bottom coil supporting portions to engage the 6 length of coil between a coiled stack in said receiving means and the stack being formed on said supporting bottom.
  • said cutting means includes a separate cutting element located at at least diametrically opposite locations on each side of said receiving means, and catching means for engaging a length of cable and directing it into association with a selected one of said cutting elements.
  • a device including a cylindrical guide shaft located between said treatment shaft and said coil stack supporting bottom and including guide means for forming the coils into a uniform vertical stack as it is delivered from said treatment shaft onto said coil stack supporting bottom.
  • said means for guiding said shaft bottom parts includes a guideway formed on each side of the bottom of said shaft, roll means supporting said bottom parts for movement along said guideway, said guiding arm including a member extending obliquely downwardly from the rim of said shaft and terminating in a portion extending into said shaft for contacting the ends of the wire being formed to urge them against the opposite wall of said shaft, said cutting means including means to direct the length of wire between the dropped stack and the coiled wire being directed to said shaft bottom and move it into association with said cutting means.
