Definitions

  • This invention relates to switching means, and more particularly to apparatus arranged .to cause the rolled product of a rolling mill selectively to enter any one of a number of paths.
  • t is also sometimes necessary to produce coils of rod of a weight less than the weight of the billet or bar from which the rod was rolled. For these reasons it becomes necessary to sometimes cut the rod into shorter lengths and to cause each length to pass to a specific reel. It is normal practice to coil the entire product of a mill by the use of several reels, but it is necessary that the lengths of the rod pass to one reel after another in succession and that a length be introduced again to the first reel of a series only after the other reel of the series have been successively used. By that time the first reel has coiled its length of rod, has discharged it, and is ready for another rod.
  • Apparatus has been conceived and built in the past to direct divided lengths of rod to various reels but, as the speed of rolling mills increased, it becomes more and more diificult to so direct the rod. Attempts to'solve the problem have been very complicated and expensive. These and other difiiculties experienced wit-h the prior art devices have been obviated in a novel manner by the present invention.
  • Another object of this invention is the provision of a switching means consisting of a shear and switch so related as to give accurate placement and introduction of successive lengths of rolling mill product to desired paths.
  • a further object of the present invention is the provision of a switch of simple and rugged construction for introducing the front ends of lengths of rolling mill product into desired paths.
  • Another object of the invention is the provision of apparat-us for cutting rapidly moving lengths of material and directing the parts into desired paths.
  • FIG. 1 is a plan view of a portion of the rolling mill incorporating the principles of the present invention
  • FIG. 2 is an elevational view of the switch of the present invention taken along the line IIII of FIG. 1;
  • FIG. 3 is a vertical sectional view of the apparatus taken along the line IIIIII of FIG. 1;
  • FIG. 4 is a horizontal sectional view of the switch taken along the line IV1V of FIG. 2;
  • FIG. 5 is a sectional view of a portion of the invention taken along the line V-V of FIG. '2;
  • FIG. 6 is an enlarged elevational view of a portion of the switch taken along the line VIVI of FIG. 4.
  • a switch means is shown in use in conjunction with other elements of a rod rolling mill.
  • a conduit 11 adapted to carry rod from the last stand of a rolling mill approaches one side of the apparatus.
  • switch pipes 12 lead to intermediate pipes 13 which lead to another set of pipes 14.
  • the pipes 14 terminate in a housing 15 which carries the entrance end of pipes 16, 17, 18 and 1% which lead through a cooling apparatus 21, 22, 23 and 24, respectively, to reels 25, 26, 27, and 28.
  • the switching means 10 consists generally of a shear 29 and a switch 31. Referring to FIG. 3, it can be seen that the conduit 11 terminates close to the blades 32 and 33 which are mounted on knife holders 34 and 35 respectively, of the shear 29.
  • the switch consists of a housing 36 mounted on a base 37.
  • the housing con sists of a front wall 38 land a rear wall 39 joined by a curved peripheral Wall -41.
  • Extending between the two walls at equally spaced points close to their peripheries are four shafts 4-2 on which are rotatably mounted wheels
  • On either side of each wheel 43 are mounted smaller wheels 44.
  • Held within one roup of smaller wheels is an internal disk 4-5, while a similar internal disk 46 is held within the other group of four smaller wheels.
  • the large wheels 43 lie in the space between the two internal disks which are held in spaced parallel relationship.
  • a switch body 47 holding between the disks, which are provided with circular central apertures, is a switch body 47 having two bores extending therethrough, one bore having a sleeve 48 and the other bore having a sleeve 49.
  • a ring 5 1 Fastened to the outwardlyfacing surface of the internal disk is a ring 5 1 which extends through and occupies the entire area of the aperture in the rear wall 39 of the housing.
  • a horn 52 Fastened to the outwardly facing surface of the internal disk 46 is a horn 52 which is generally funnel-shaped and is provided with a central flat wall 53 which divides the horn into an upper passage 54 aligned with the sleeve 48 and a lower passage 55 aligned with the sleeve 49.
  • the wall 53 extends well Within the area subtended by the drums 34 and 35 of the shear 29 and the walls of the horn are cut back with a sweeping curve from the end of that wall to avoid the path of the knives 32 and 33 as the shear rotates.
  • the line of rotation of the internal disks 45 and 46 with the sleeves 48 and 49 and the horn 52 is an axis parallel to and midway between the axes of the sleeves 48 and 49.
  • the passage 55 and the sleeve 49 are aligned generally with the path occupied by a rod as it goes through the shear when the shear knives are away from cutting position, i.c., with the rod 56 Occupying the lower position resting on the lower surface of the conduit 11.
  • the new front end will be supponted in an upper position by the lower blade 33 and occupies the solid line position wherein it is aligned with the passage 54 and the sleeve 48.
  • a bracket 57 which supports the adjacent ends of the pipes 12.
  • the switch body 47 is formed with a pinion 58 whose teeth are engaged by the teeth of a horizontal rack 59 which is fastened to the piston of a horizontally-arranged, pneumatic linear actuator 61.
  • the housing 36 is provided with an elongated chamber 62 adapted to receive and enclose the end of the rack 59 in the extreme outer position of the actuator 61.
  • FIG. 5 is shown a somewhat enlarged view of the section of one of the areas in the housing containing a shaft 42, particularly showing the method of lubrication and also the manner in which the rack 5'9 rests on a wheel 63 and is provided with grooves on its under side which are engaged by two large wheels 64 and 65.
  • the small wheels 44 engage the internal disks 46 and and between these disks lies the switch body 47 with its pinion 58 engaging the teeth on the rack 59.
  • FIG. 6 shows particularly well the appearance of the horn 52 which is integral with a disk '66 bolted to the internal disk 46. It is evident in this view that the cross section of the horn is generally rectangular with the long direction arranged vertically and with the wall 53 extending across its central portion.
  • a length of rod which has been finished in the rolling mill arrives at the apparatus through the conduit #11, the passing of its front end having been duly noted down-stream by suitable signal flag which started the shear 29 rotating.
  • the presence of the front end of the rod 56 is duly noted by a photoelectric cell 67 which is located beside the shear and which is directed toward the end of the conduit 11. Since the blades of the shear have not yet entered the neighborhood of the rod, the rod rests on the lower surface of the conduit 11 and, therefore, passes through the shear into the lower passage -of the horn 52 of the switch 31. It'passes then through the sleeve 49 onto one of the pipes 12.
  • the upstream end of the pipes 12 are arranged vertically, one above the other, so as to align with sleeves 4? and 49.
  • the pipes 12 ape spread apart and in the same horizontal plane and are aligned with parallel, generally-horizontal pipes 13.
  • the pipes 13 are pivotally movable about their upstream ends and are moved by a hydraulic actuator in the usual way. In the uppermost position the pipes 13 are aligned with upper pipes 14, while in a lower position are aligned with a crop pipe.
  • Each of the two upper pipes 14 is rnovable vertically by a suitable actuator and is able to direct rod to one of the pipes 16 and 18 or 17 and 19 leading to the reels 25 and 27 or 26 and 28.
  • the linear actuator 61 is set in motion to act through the rack 59 to rotate the Whole internal apparatus including the horn 52 and the sleeves 48 and 49.
  • the operator or, in some cases, automatic mechanism
  • the linear actuator 61 will cause the linear actuator 61 to rotate the horn so that the passage 55 is uppermost and the passage 54 is in the low position. Since the blade 33 is out of the way by the time the reversal is completed, the rod is free to move downwardly with its passage and, so, it occupies the dotted line position in FIG. 3.
  • the next piece enters the passage 55 which is now in the uppermost position and, after the rod is well introduced into the system through the switch, the switch is again reversed so that the passage 54 is uppermost again.
  • a cut will be made of a short length at the front and a short length at the rear of the rod. These are known as crops and it is desirable to dispose of them.
  • the pipes 14 are inclined downwardly to align themselves with the crop pipe Whch underlies pipes 14 and the cropped front end goes through the crop pipe for disposal.
  • the rest of the lengths of rod are suitably directed toward the pipes 216, 17, 13 and 19 and toward their respective reels by manipulating the pipes 13 and 14.
  • the operation of the shear, switch, and pipes may take place by use of photoelectric cells and other automatic apparatus, or it may be done by hand. It can be seen, however, that the use of the reels may take place in a predetermined sequential order with positive, accurate switching and with no danger of a rod being introduced into a pipe which already contains a rod or into a reel which has not yet discharged its coil.
  • Apparatus for shearing into a plurality of separate pieces an elongated product running at high speed and for switching said pieces alternately into separate paths comprising, a conduit for delivering said elongated product along a pass line, a switch body having two spaced parallel bores extending therethrou'gh, means normally positioning said body with said bores one above the other, means mounting said body for rotation about an axis above and 7 parallel to the extension of said pass line and longitudinally spaced from the delivery end of said conduit, 21 pair of funnel-shaped guides attached to said body and diverging from the input ends of said bores toward said conduit, said guides having a common horizontal wall in line with said axis of rotation, a rotary shear positioned between said conduit and said tubular guides for severing said product, the lower blade of said shear after a cut is made elevating the free end of said product to a position above said horizontal wall and into the upper one of said guides,
