The outer wall of the positioning rod 508 is fitted with a positioning sleeve 509. A reinforcing roller 510 is fixed between the positioning sleeves 509. A cold rolling roller 511 is provided at the lower end of the reinforcing roller 510. A second motor 512 is fixedly provided on the lower outer wall of the second adjusting frame 502. A pin 513 is provided at the output end of the second motor 512. A pin shaft 514 is fitted on the outer wall of the pin 513. A moving rod 516 is inserted into the inner wall of the bottom end of the first adjusting frame 501. A shaft rod 517 is fitted on the outer wall of the moving rod 516. A shaft sleeve 515 is fitted at the front end of the shaft rod 517. A limit bolt 518 is threaded into the lower outer wall of the first adjusting frame 501. A connecting frame 8 is fixed between the outer walls of the first adjusting frame 501 and the second adjusting frame 502.

[0025] The worktable 1 and the bidirectional lead screw 3 are symmetrically provided with a second slide rod 6. The outer wall of the second slide rod 6 is movably fitted with two sets of symmetrical second slide sleeves 7. The first ball screw sleeve 4 and the second slide sleeve 7 are respectively fixedly connected to the second adjustment frame 502 and the first adjustment frame 501.

[0026] The inner walls of the first adjusting frame 501 and the second adjusting frame 502 both have grooves that mate with the second ball screw sleeve 507 and the first sliding sleeve 519. The ball screw 503 is rotatably inserted into the grooves, and the worm 505 and the worm wheel 504 mesh with each other.

[0030] A PLC controller 9 is fixedly installed at the bottom of the workbench 1. The first motor 2 and the second motor 512 are both electrically connected to the PLC controller 9.

[0031] When it is necessary to adjust the thickness of the cold rolling, the first motor 2 can be started by controlling the PLC controller 9. The first motor 2 drives the bidirectional lead screw 3 to rotate. The two sets of first ball screw sleeves 4 slide along the outer wall of the bidirectional lead screw 3. The first ball screw sleeves 4 drive the second adjusting frame 502 to move. The second adjusting frame 502 drives the first adjusting frame 501 to move through the connecting frame 8. The first adjusting frame 501 slides along the outer wall of the second sliding sleeve 7 through the second sliding rod 6, increasing the stability of the first adjusting frame 501 and the second adjusting frame 502 during the movement. The two sets of cold rolling rolls 511 move away from each other or closer to each other as the first adjusting frame 501 and the second adjusting frame 502 move away from each other. When the distance between the cold rolling rolls 511 reaches the appropriate cold rolling distance, the first motor 2 is turned off and the second motor 512 is started to drive the cold rolling rolls 511 to rotate. The two sets of cold rolling rolls 511 can perform cold rolling on the nickel strip passing between the cold rolling rolls 511.

[0032] The lower end of the reinforcing roller 510 is always in contact with the cold rolling roller 511. The reinforcing roller 510 can prevent the cold rolling roller 511 from deforming during the cold rolling process. When the cold rolling roller 511 is damaged or needs maintenance, rotate the limiting bolt 518 to unscrew the limiting bolt 518 from the screw hole in the shaft 517, slide the shaft 517 along the moving rod 516 to move the front end of the shaft 517 out of the insertion hole in the bushing 515, and then push the cold rolling roller 511 to move the slot in the pin 514 out of the pin 513. This completes the disassembly of the cold rolling roller 511, making it convenient for workers to replace or maintain the cold rolling roller 511.

[0033] When the reinforcing roller 510 needs to be installed, the positioning sleeves 509 at both ends of the reinforcing roller 510 are fitted onto the positioning rod 508. The positioning rod 508 passes through the positioning holes opened in the positioning sleeves 509. The worm gear 505 is rotated to drive the worm wheel 504 to rotate. The worm wheel 504 drives the ball screw 503 to rotate. The ball screw 503 drives the second ball sleeve 507 to move along the groove. During the movement of the reinforcing roller 510, the first sliding sleeve 519 slides along the outer wall of the first sliding rod 506 to increase the stability of the reinforcing roller 510 during the movement until the reinforcing roller 510 and the cold rolling roller 511 are in contact and the rotation stops. Due to the frictional wear between the outer walls of the cold rolling roller 511 and the reinforcing roller 510, the position of the reinforcing roller 510 is adjusted periodically to ensure that the reinforcing roller 510 and the cold rolling roller 511 are always in contact, avoiding frictional wear between the reinforcing roller 510 and the cold rolling roller 511. The reinforcing roller 510 cannot play a role in reinforcing and supporting the cold rolling roller 511.
