Description

Technical Field

[0001] This invention relates to the field of rolling mill equipment technology, and in particular to a rolling mill changing device. Background Technology

[0002] Most domestic continuous casting and rolling copper rod production lines are CR3500 lines, producing Φ8 copper rods. The rolling mill section of this line consists of 12 individually driven stands. The first six stands have roll ring diameters of 360 mm, and the upper and lower rolls in all stands are symmetrically adjusted. These six stands have a total of 12 rolls, each weighing approximately 60 kg. The symmetrical rolls in the stands are arranged in both vertical and horizontal configurations.

[0003] Rolls directly affect product quality during production, resulting in frequent roll replacements. Currently, maintenance personnel typically replace rolls manually, a laborious and dangerous process due to the rolls' weight. Therefore, we propose a roll replacement device. Summary of the Invention

[0068] As a preferred embodiment of this example, Figures 1-12 As shown, the bottom of both the left clamp 73 and the right clamp 74 is arc-shaped and adapted to the outer dimensions of the roll.

[0070] As a preferred embodiment of this example, Figures 1-12 As shown, the rotation angle of the cantilever 35 is between 0° and 60°. When the rotation angle of the cantilever 35 is 0°, the top of one end of the cantilever 35 contacts the bottom of the limiting rod 310.

[0071] In this embodiment, the rotation angle of the cantilever 35 rotation angle is further limited.

[0072] Working principle of the invention: In the initial state, the electromagnet 22 is magnetically fixed to the track beam 1. The first fixed sleeve 23 and the first connecting sleeve 32, the second connecting sleeve 52 and the second fixed sleeve 38, and the third connecting sleeve 62 and the connecting arm 54 are all rotatably connected. Therefore, the position of the support frame 61 can be freely adjusted to move it to the roller placement position. Then, the controller 8 controls the hydraulic clamping assembly 7 to clamp the roller. In use, the controller 8 synchronously controls the second hydraulic telescopic rod 71 and the third hydraulic telescopic rod 72 to retract, and respectively drives the left clamping frame 73 and the right clamping frame 74 to move inward synchronously, thereby clamping the roller. When it is necessary to move the position of the roller, the slide 21 needs to be separated from the track beam 1, and the first fixed sleeve 23 and the first connecting sleeve 32 are rotatably connected to the track beam 1. 3 is fixed to the first connecting sleeve 32, the second connecting sleeve 52 is fixed to the second fixed sleeve 38, and the third connecting sleeve 62 is fixed to the connecting arm 54. This allows the sliding block 21 to move along the surface of the track beam 1 when the support frame 61 is moved. When fixed, the controller 8 controls the operation of the fixed conductive mechanism 33, the first fixed mechanism 53, and the second fixed mechanism 63 respectively. The fourth hydraulic telescopic rod 3311 in the fixed conductive mechanism 33 extends and synchronously drives the first drive frame 339 and the first toothed part 3310 to move upward. During the upward movement, it synchronously drives the first drive gear 338 and the first threaded sleeve 335 to rotate. The rotation of the first threaded sleeve 335 synchronously drives one end of the two sets of first abutment blocks 336 to extend through the first through groove 337. An outer cylinder 331 is placed outside and abuts against the inner wall of the first fixed sleeve 23. By increasing the friction, the first connecting sleeve 32 and the first fixed sleeve 23 are fixedly connected. At the same time, the first drive frame 339 moves synchronously to lift the upper guide rod 332 and the annular conductive block 333, and stretches the spring 334. During the upward process, the annular conductive block 333 separates from the two sets of semi-rings. When the annular conductive block 333 is not in contact with the two sets of semi-rings, the series circuit is de-energized (conversely, when the annular conductive block 333 is in contact with the two sets of semi-rings, the series circuit is energized). When the series circuit is de-energized, the electromagnet 22 stops running and is no longer magnetically fixed to the surface of the track beam 1. The slide 21 can then move. The fifth liquid in the first fixing mechanism 53 and the second fixing mechanism 63... The extension rod 538 extends upward, simultaneously driving the second drive frame 536 and the second toothed part 537 to move upward. During this upward movement, it simultaneously drives the second drive gear 535 and the second threaded sleeve 533 to rotate. The rotation of the second threaded sleeve 533 simultaneously drives one end of each of the two sets of second abutment blocks 534 to extend outside the second outer cylinder 531 through the second through groove 532, and abut against the inner walls of the second fixed sleeve 38 and the connecting arm 54 respectively. By increasing the friction, the second connecting sleeve 52 and the second fixed sleeve 38 and the third connecting sleeve 62 and the connecting arm 54 are fixedly connected. This completes the fixing operation. Since the fixing conductive mechanism 33, the first fixing mechanism 53 and the second fixing mechanism 63 can be controlled separately, they can be freely controlled according to the actual situation.The device exhibits good performance. It also includes a fixed gear 34, a horizontal mounting base 36, a rotating gear 37, and a chain belt 39. Through the cooperation of these components, the horizontal mounting base 36 remains horizontal regardless of the swing of the cantilever 35, facilitating the installation of the rolls and resulting in excellent performance.
