I DIE ROLLING Filed April 25, 1936 2 Sheets-Sheet 2 Inventor.- 514MUEL 5. WE55TEE,
Patented Dec. 20, 1938 UNITED STATES PATENT OFFICE Application April 23,
1 Claim.
This invention relates to die-rolling and more particularly to means for enabling the accurate registry of the matrices of the die-grooves in the coacting working surfaces of the die-rolls.
In the rolling of series-connected articles, the most prevalent practice is to employ a pair of die-rolls which are geared together and connect one of the same to a source of power. According to this practice at least one of the gears which connect the die-rolls is so mounted that it may be released from the die-roll on which it is carried. In this manner the matrices of the coacting die-grooves may be correctly adjusted at the time the die-rolls are installed in the mill and subsequent thereto. This procedure must, however, be confined to such times when the mill is not operating; and, in addition, requires considerable time.
There are a number of prior devices which seek to enable the adjustment of die-rolls without discontinuing the operation of the mill; but they are expensive to install, cumbersome and require considerable time to operate.
It is among the objects of the present inven- 25 tion to enable a rapid and extremely accurate peripheral alinement of die-rolls by a compact device which is easily and inexpensively installed.
The foregoing and other objects will be apparent after referring to the drawings, in which:
Figure 1 is a fragmentary sectional end elevation of a die-rolling mill employing the device of the invention.
Figure 2 is a side elevation of the device of Figure 1.
Referring more particularly to the drawings, the numeral 2 designates a roll housing which carries a pair of rotatable die-rolls 3. These dierolls 3 are peripherally grooved and provided within the grooves with spaced article-forming 40 matrices 5. The shaft 6 of each die-roll 3 carries a gear 1 which may be permanently attached.
Each of the shafts 6 also carries a yoke 9 in the form of a pair of spaced arms. Between the outer ends of the arms of each yoke 9 there is mounted a shaft H) on which there is carried a gear l2.
The gear I2 on the yoke 9, which is carried by the shaft 6. of the upper die-roll 3, meshes continuously with the adjacent gear 1; while its counterpart meshes continuously, and in the same manner, with the gear I on the shaft 6 of the lower die-roll 3. The two shafts Ill are connected together by a pair of links l3, which thereby hold the gears I2 in mesh with the gears 1 and. in proper pitch circle center distance with respect thereto. Y
1936, Serial No. 76,019
Referring to Figure 2, the shaft H] which is mounted between the outer ends of the arms of the lower yoke 9 is extended outwardly therefrom, as shown at M. This extension l4 carries a downwardly extending pivotal link l5 which is 5 screw-threaded on its extended end, as shown at I6. A similar but upwardly extending pivotal link I! is carried by the roll housing 2. The link I! is screw-threaded on its extended end, as shown at I8, but reversely with respect to the screw-threads IS on the link 15. The screwthreaded ends 16 and 18 of the links I5 and I1 respectively are connected together with a turnbuckle 20 and provided with lock-nuts 2|.
During the rolling operation, improper peripheral alinement of the die-rolls 3, when observed from the condition of the work-piece, may be easily and accurately corrected by turning the turnbuckle and lowering or raising the pivotal link [5. This effects the partial revolution of the 20 gear l2 on the lower yoke 9 around the gear I on the lower die-roll 3 for a limited distance without any peripheral movement of the gear 1 on its axis. The gear 12 on the upper yoke 9 will be reversely revolved on its axis and will in turn cause the gear I on the upper die-roll 3 to revolve in the same direction as the gear l2 on the lower yoke. Therefore, in effect, the lower gear 1 remains stationary while the upper gear 1 is slightly revolved, thereby adjusting the artiole-forming matrices 5 in a very accurate and efiicient manner.
While I have shown and described one specific embodiment of my invention, it will be understood that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined by the following claim.
I claim:
In a die-rolling mill, a die-roll, a gear secured to said die-roll, a yoke carried by and extended from said die-roll, a gear carried by said yoke, said gear being held in mesh with the gear secured to said die-roll, a second die-roll, a gear secured to said second die-roll, a yoke carried by and extended from said second die-roll, a gear carried by said last-named yoke, said last-named gear being held in mesh with the gear secured to said second die-roll, means connecting said yokes, said means being constructed and arranged to hold in mesh the gears carried by said yokes, and means for adjusting the position of the means connecting said yokes whereby the relative peripheral position of opposed parts of said dierolls may be adjusted.
