HYDRAULIC INGOT-TBIMMING PRESS.

Application filed August 31, 1923. Serial No. 660,410.

To all whom z't may concern.'

Be it known that I, ALPHoNso DE CLAUDE KEssLER, a citizen of the United States, residing at Dunkirk, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Hydraulic Ingot-Trimming Presses, of which the following is a specilication.

This invention relates to trimming machines and has for its object the provision of a novel device .for trimming bars, ingots or billets of iron, steel and the like whereby to remove surface imperfections, flaws, roughnesses, seams 4and the-like, so that the bar, ingot or billet will be in proper condition to Ibe passed to the rolling machine for subsequent treatment. Y

An important and more specific object 1s the provision of a machine of this character in which use is made of a hydraulic press .for forcing the hot billet or ingot thnough the set of trimming cutters, the cutters being positively rotated in opposition to the travel of the ingot and being power driven.

Another object is the provision of hydraulic press operated means for leading the ingot into the guide to the cutters.

Another object is the provision of a machine of this character which is provided with means for adjusting the cutters to vary the distance therebetween for treating billets of different sizes `or for cutting billets' to different depths depending upon different conditions. f An additional object is the provision of a machine of this character which will be' simple and inexpensive to manufacture, easy to control and operate, positivein ,ction, efficient and durable in service vand t general improvement in the art. y

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described andclaimed and illustrated in the accompanying drawings, in which: A

Figure 1 is a somewhat diagrammatic side elevation of the device showing it associated with a furnace and a trolley,

Figure 2 is a side elevation of,the device alone on a larger scale,

Figure 3 is a longitudinal section,

` res 4, 5 and 6 are detail sections Y showing the valve itions,

Figure 7 is a horizontal section on the line practice I employ are bolted or otherwise secured to the bot- Figure 8 is a similar view on the line 8--8 l cally, a suitable furnace from .which hot ingots are ltaken by means oftongs B carried y a trolley runway C which permits the ingot or billet to be brought to my machine. In carrying out my invention 'L provide an upright supporting frame 15 of any desired or preferred constructionv and this frame may be formed as a single casting-or constructed of any suitable number of parts, bolted, riveted or otherwise secured together.

Secured to and rising from the base portion of this frame are upright rods 16 upon the upper ends of which is secured a platform 17 on which is mounted a hydraulic cylinder 18. The inlet and outlet of liquid to this hydraulic cylinder is through pipes 19 and 2() and any suitable control means, not shown, is of course provided for permitting inlet ofwater into and outlet of water from this c linder. The platform is necessarily provi ed with a hole through which passes the cylinder plunger rod 21 which is carried by a piston 22.

Located above the base frame 15 is a cage structure designated broadly lby the numeral 23 which is formed from a plurality of slats 24: connected by up rand lower U-shaped members 25 which ave their forward ends curved outwardly to define guides to the interior of the cage. the cage structure is open as clearly disclosed. Any desired means might be provided for supportin this cage, but in actual bracket arms 26 which tom of the cage and which are carried upon This side of. l

one or more of the urights 16. This cage is in such ition at -it is immediately below the p unger rod 21. Hinged at 27 is a door 2 8 which is for the urpose of closing the cage and'forthe additionall purpose o serving as a guide chute for conducting bars or billets into the machine. The relative arrangement of the parts is such that when the door 28 is in its down swung position an ingot carried by the tongs B may be placed upon the door.

To tilt the door for the purpose of sliding the ingot into the cage, I provide a support 29 upon which'is mounted a hydraulic cylinder 30 containing a piston 31 carried by.

a plunger rod 32 which is slidable along the support 29 and with which is pivotally connected a link 33 which is in turn pivoted at 34 on the door 28. The vcylinder 30 is provided with pipes 35 which are necessarily valve controlled and which permit inlet and outlet of water into and from the cylinder for moving the lunger.

At opposite si es the upper portion of the frame 15 is formed with guides 36 within which are slidable pairs of bearings 37 within which are journaled shafts 38 carrying cutters 39. Each of these cutters is shown as being of double truncated cone shape or tapered inwardly from both ends towards the center for conforming engagement upon a corner of the bar or ingot to be trimmed. These cutters might vary in actual construction, though a convenient arrangement Vis to construct these cutters as rollers formed with longitudinal grooves within which are mounted cutting blades 40 which might be replaced when worn or excessively dull. The cutters 39 are designed to act upon two diagonally opposite corners of the billet for trimming olf imperfections.

' To regulate the distance between the cutters for working upon billets of different sizes and for making cuts of different depths on the sides of the billet, I provide screws 41 which are threaded through the frame, which project into the guides 36 and which have a swiveled connection with the bearings 37. At their outer ends these'screws are equipped with handles 42 for eii'ecting rotation thereof At the lower portion of the frame the other-two opposite sides are provided with guides 43 within which are slidably mounted pairs of bearings 44 within which are journaled shafts 45 carrying cutters 46 similar in construction to the cut-ters'39 but so positioned as to act upon the other. two dji-v agonally opposite corners of the ingot or billet. The cutters 46 are likewise adjustable by means of screws 47 threaded through the frame and swivelly connected with the bearings 44. The outer ends of the screws 47 carry j handles 48 whereby rotation may be imparted to the screws for shiftingthe rollers.

Each bearing includes a relatively stationary section within which 'is mounted a relatively movable section and I provlde set screws 49 equipped with lock nuts 50, for the purpose of makinga micrometer adjustment onthe bearings to insure alignment of the center lines of the cutters. Between the two palrs of cutters, I provide suitably mounted angular guides 51 and below the lowermost cutters, I rovide other similar guides 52 whlch are owever located at right angles with respect to the guides 51; In other words the guides.51 between the two pairs of cutters engage against opposite corners of the billet or ingot when the nose thereof passes by the first cutters and acts to guide the billet to the lower cutters. The guides 52 are forl the purpose of conducting the trimmed billet into a. suitable discharge chute 53 from which the ingots pass to the rolling machine in connection with which my device is used.

To prevent excessive overheating of the cutters while in service, I provide a set of pipes54 which are located adjacent the cutters and which. are connected with any suitable source'of water supply. These pipes are perforated so that they-will discharge small streams or jets of water onto the cutters for preventing them from heating to such an extent as to lose their temper. The specific arrangement of pipes is disclosed in the drawing but is not disclosed in detail for the reason that it may be varied to suit the requirements of the individual manufacturer.

In order to effect driving of the cutters, 'I provide a drive shaft 55 on which are splined bevel gears 56 which mesh constantly with bevel gears 57 on the ends of the cutter shafts 45. The splining of the gears 56 on the shaft permits these gears to remain always in mesh with the gears 57 regardless of the adjustment of the cutters toward or away fromeach other and it is preferable to provide brackets 58 which operate to hold the gears in mesh, these brac ets depending from the bearing 44. The shaft 55 also carries a sprocket 59 about which is trained a chain 60 which is in turn trained about a sprocket 61 on a countershaft 62. On-the shaft 62 is a bevel gear 63 meshing with a bevel gear 64 on a second counter-shaft'65. Splined on the shaft 65 the tongs B and deposited on the door 28.

Water is then let into the lower one of the pipes 35 in the cylinder 30 whereupon the plunger rod- 32 will be forced upwardly, swinging the door 28 into vertlcal ositlcn closing the previously open side of t e cage 23; The ingot or billet then slides down the door 28 along the cage and engages the top most cutters 39. 'Watervis admitted through the pipe 19 to the cylinder 18 and the plunger rod 21' is forced downwardly by the pressure until it engages the ingot, whereupon continued pressure will cause the ingot to be forced down between the pairs of rollers which operate to cut away all surface flaws, seams and other imperfections, so that when therbillet reaches the discharge chute 53 it will be in proper condition to be run through the rolllng mill.

From the foregoing description and al study of the drawings it will be apparent that I have thus provided a simply constructed and consequently easily controlled and operated trimming machine which will be very eiicient for the purpose Aspecified and which will be a eat saver of time and labor and material, inasmuch as all the ingots or billets are reduced -to thesame size and to a perfect condition before being admitted to lthe rollin machine. Adjustin means has been provided to take care of al desired variations and to meet different conditions and as a consequence the machine proves to be highly satisfactory in performv in all of its functions.
