WATER COOLING APPARATUS FOR DRAWING BLOCKS Filed June 30, 1960 3 Sheets-Sheet 3 INVENTOR. 6 ,454 0. 5053745 United States Patent 3,017,017 WATER COOLING APPARATUS FOR DRAWING BLOCKS Carl 0. Bruestle, Metuchen, N.J., assignor to Syncro Ma= chine Company, Perth Amboy, N.J., a corporation of New Jersey Filed June 30, 1960, Ser. No. 39,980 7 Claims. (Cl. 20520) The present invention relates to means for cooling drawing blocks of wire drawing machines and particularly to means for cooling finishing blocks by means of cooling water supplied within the block during its rotation.

More particularly still the invention relates to the cooling of finishing or coiling blocks of the type in which the block is divided into sectors in order that a tool for removing the finished coil may be inserted, which renders it impossible to utilize the usual water cooling arrangements.

The cooling arrangements of the present invention are such that it is possible to utilize coiling blocks of different dimensions therewith, the cooling apparatus being so arranged that differently dimensioned blocks may be mounted upon a drive shaft and readily, by the act of mounting, connected so that cooling water is supplied thereto and exhausted therefrom.

Other objects and features of the invention will be apparent when the following description is considered in connection with the annexed drawings, in which,

FIGURE 1 is a top plan view of a sectored or slotted finishing block illustrating particularly the type of block to which the present invention is applied;

FIGURE 2 is a vertical cross-sectional view taken on the planes of the line 2-2 of FIGURE 1 showing the construction of the cooling apparatus of the instant invention;

FIGURE 3 is a horizontal cross-sectional view taken on the plane of the line -33 of FIGURE 2 and showing partioularly the arrangement of water inlet and outlet ports;

FIGURE 4 is a horizontal cross-sectional view taken on the plane of the line 44 of FIGURE 2 and showing additional details of the water inlet system;

FIGURE 5 is a top plan view of a tool which fits into the slots of the finishing block and underlies the wire coiled upon that block so that at periodic intervals the coiled wire may be stripped or removed from the finishing machine block; and

FIGURE 6 is a side elevation of the tool of FIGURE 5.

Referring now to the drawings and particularly to FIG- URE 2, there is shown therein the usual shaft 10 on which the sectored drawing block, generally designated 11, is mounted. Shaft 10 is provided with the usual bearings 12 and is driven in any suitable manner.

As indicated above, the drawing or finishing block is formed of four sectors 10a, between which are the slots 19. This arrangement provides for use of a wire coil removing tool as hereinafter described.

The drawing block 11 is mounted on the shaft 10 by virtue of a tapered portion 13 of the hub of the drawing blocks which mates with a similarly tapered portion of shaft 10, the block being securely fixed on the tapered shaft by means of a suitable fastening such as the screw 14.

Fixed to base 15 and concentric with the shaft 10, is a cup-shaped member 16 having an aperture 17 through which shaft 10 and a sleeve 18 thereon passes. Surrounding the aperture 17 is a water sealing ring 20. Integral with member 16 and extending upwardly is a circular flange 21 which carries the sealing ring 22 and the split retaining ring 23.

Mounted for rotation with shaft 10 is the sleeve 18 having four longitudinal holes 25 therein. Sleeve 18 is formed with grooves 26 and 27 in its outer surface, these grooves mating With the

rings

23 and 22 respectively. Ring 23 is, as explained above, a split retaining and location ring while ring 22 is a sealing ring. Adjacent the top thereof each hole 25 is formed with a groove in its wall and an O-ring 28 is placed in each of these grooves. In a similar manner the inner surface of sleeve 18 is formed with a groove near its upper end and an O-ring 30 is placed in this groove and prevents water from creeping along the shaft 10.

As has been indicated heretofore, water is supplied through a pipe 31 to casing portion 29 formed on member 16 and to the chamber 32 formed by the member 16, flange 21 and sleeve 13. As will readily be seen, since this chamber is supplied with water under pressure there is a flow of water into the holes 25.

The hub portion 24 of drawing block 11 is provided with four passageways therein, these passageways having vertical portions designated 33, each joining a substantially horizontal portion 34 which enters: the block above the integral sector members or plates 35. At the lower end each passageway 33 is enlarged and a tube 36 is fastened therein, the tube protruding from the lower face of the hub portion of block 11.

It will be seen that by means of this arrangement the drawing block may be removed by simply loosening the nut 14 and removing the tapered hub from the tapered portion of shaft 10. The tubes 36 will thus be withdrawn from the holes 25 and a diiferent drawing block, supplied however, with like tubes 36, may be inserted, the water seal being completed by this insertion due to the use of the O-rings 28. The sectors are closed by means of plates 37 fixed by suitable means, such as screws 38, to the hub and rim of block 11.

As indicated hereinabove, water flows into the chamber of member 26 and thence through tubes 36 and passageways 33 and 34 onto the upper surface of the sector members 35. A series of holes 40 is provided around the periphery of each sector member 35 adjacent the inner surface of the vertical portion of drawing block 11. Thus water is discharged from the sector plates and runs downwardly over the inner surface of the drawing block cooling that block and providing for heat transfer from the drawn Wire which is, as is well known, at a relatively high temperature.

Water is discharged through one or more ports indicated at 41, FIGURE 4, and may be sent to waste or cooled and recirculated.

The construction of block 11 is such that a water seal is provided to prevent water escaping from the discharge chamber indicated at 42. Although this water sealing means forms no part of my invention it comprises the disk 43 fixed to the base 15 by means of the bent off flange 44, and having the upwardly extending

cylindrical portions

45 and 46 adjacent the lower end of the drawing block. The block is provided with the usual flange 47 and with the downwardly extending annular ribs 48 and 50. As will be obvious, any water flowing down the inner surface of the block 11 is carried by the annular rib 50 below the upper edge of rim or flange 46 and cannot, therefore, be centrifugally thrown outwardly. Should the level of water in the chamber 42 at any time exceed the height defined by the upper edge of annular flange 46, it still could not flow outwardly due to the fact that flange 48 extends upwardly to a much greater extent.

It will be seen from the foregoing description that cooling water is caused to flow in a relatively thin layer over the inner surface of block 11 to thereby cool the wire thereon and that this is possible even though the drawing block is provided with the slots between sectors.

Before starting the machine the coil removing device shown in FIGURES 5 and 6 and comprising the central shaft 51 having four collapsible angled arms 52 radiating therefrom at the 90 points of a circle is positioned with the arms 52 extending into the slots and with the ends 59 underlying the lowermost coil of wire, as shown in dashed lines in FIGURE 2. The removing device 51 is provided at its top with an integrally formed ring 53 adapted to be engaged by the hook of a crane. Thus when wire has been drawn to an extent that the finishing block has a desired amount coiled thereon, the machine is stopped, the wire cut, and a crane then engages the eye 53 and lifts the device 51. Since the arms lie beneath the entire wire coil then on the finishing block, this coil is lifted off by the member 51. It is to be noted that the arms 52 lie below the level at which flange 47 meets block 11 and consequently are below the first turn of wire on the finishing block.

While I have described a preferred embodiment of my invention, it will be understood that I wish to be limited not by the foregoing description, but solely by the claims granted to me.
