[0016] Combination Figures 1 to 4 As shown, a sliding blank rolling mill includes a frame 1 at the bottom and a rolling mechanism 4. The rolling mechanism 4 contains a power box 40, and a rolling head 41 is coaxially connected to the lower side of the output shaft of the power box 40. A rotating spindle 5 is located on the lower part of one side of the frame 1, and an open-top roller 51 is located on the upper part of the rotating spindle 5. A rotary mold 22 is located inside the roller 51. A sliding track is located on one side of the roller 51, including a first guide rail 11 and a second guide rail 21 that are perpendicular to each other. The first guide rail 11 is horizontally arranged on the upper part of the frame 1, and a first slide block 2 is slidably connected in the first guide rail 11. The second guide rail 21 is vertically arranged in the first slide block 2, and a vertical slide block 3 is slidably connected in the second guide rail 21. A first sliding drive device 110 is provided between the first guide rail 11 and the first slide block 2, providing power for the sliding of the first slide block 2 on the first guide rail 11. A second sliding drive device 210 is provided between the vertical slide block 3 and the second guide rail 21. The sliding direction of the vertical slide block 3 is parallel to the rotation center of the rotary mold 22. During use, the vertical slide block 3 moves up and down to bring the rolling mechanism 4 closer to or further away from the roller 51, facilitating the removal of the formed blank. The rolling forming of the formed blank is achieved by the horizontal sliding of the first slide block 2 on the first guide rail 11, so that the wall thickness of the blank reaches the final requirement.

[0017] The rolling mechanism 4 is hinged to the vertical slide 3 via a connecting arm 42 on one side. The vertical slide 3 is provided with a hinge box 30 on the side corresponding to the rolling mechanism 4. The connecting arm 42 is hinged to the hinge box 30 via a hinge shaft 421. The hinge shaft 421 passes through the two side walls of the hinge box 30.

[0018] An elevation adjustment mechanism is provided between the rolling mechanism 4 and the vertical slide 3. The elevation adjustment mechanism includes a limiting bolt threaded into the vertical slide 3, and the limiting bolt is positioned within the swing path of the connecting arm 42. Figure 3As shown, the limiting bolts include an upper limiting bolt 301 and a lower limiting bolt 302. The upper limiting bolt 301 is threaded into the upper wall of the hinge box 30, and the lower limiting bolt 302 is threaded into the lower wall of the hinge box 30. The opposite ends of the upper limiting bolt 301 and the lower limiting bolt 302 are respectively abutted against the upper and lower outer walls of the connecting arm 42. The connecting arm 42 is located on one side of the power box 40. The limiting bolts can limit and fix the elevation angle of the rolling mechanism 4, thereby adjusting the rolling cavity.

[0019] Combination Figure 3 As shown, a limiting rod 43 is inserted through the connecting arm 42. The limiting rod 43 is located on the side of the hinge shaft 421 away from the power box 40 and is parallel to the hinge shaft 421. The hinge box 30 is provided with an arc-shaped limiting hole 31 at the position corresponding to the limiting rod 43. The center of the center line of the arc-shaped limiting hole 31 is concentric with the hinge shaft 421. The two ends of the limiting rod 43 can slide along the corresponding arc-shaped limiting hole 31. A pull rod 32 is inserted through the upper wall of the hinge box 30. The pull rod 32 is set perpendicular to the limiting rod 43. One end of the pull rod 32 is rotatably connected to the limiting rod 43 through a joint bearing. An oblong hole 303 is provided on the upper wall of the hinge box 30 at the position corresponding to the pull rod 32. An adjusting nut 321 is provided on the side of the oblong hole 303 away from the limiting rod 43. The adjusting nut 321 is threadedly connected to the pull rod 32. The cooperation between the limiting rod 43 and the pull rod 32 enables reliable limiting of the pitch adjustment of the connecting arm 42 and the rolling mechanism 4, so that the limiting rod 43 can only pitch and swing within the range limited by the arc-shaped limiting hole 31, avoiding the risk of accidental slippage during the adjustment of the limiting bolt, while providing accuracy during adjustment and reliability during fixing.

[0020] Circular end caps 33 are fixed to the outer sides of both sides of the hinge box 30. The end caps 33 are concentric with the center line of the hinge shaft 421. An arc scale 331 is provided in the end caps 33, and a pointer part 422 is provided on one side of the arc scale 331. The pointer part 422 is fixed to the side wall of the connecting arm 42. When the rolling mechanism 4 is adjusted in pitch, the connecting arm 42 drives the pointer part 422 to move in an arc. Since the circular end caps 33 with the arc scale 331 are fixed in the hinge box 30, the pointer part 422 can accurately indicate the specific angle of the pitch adjustment, improving the adjustment efficiency and accuracy.

[0021] Combination Figures 4 to 6As shown, the first sliding drive device 110 is a first hydraulic cylinder. The cylinder barrel of the first sliding drive device 110 is fixed in the first guide rail 11. The cylinder rod 1101 at the extended end of the first sliding drive device 110 is engaged in the connecting seat 23 on the lower side of the first slide block 2. A limiting pin plate 111 is provided in the movement path of the cylinder rod 1101. One end of the limiting pin plate 111 has a notch 1110, and the end of the limiting pin plate 111 away from the notch 1110 has a limiting drive device 112. The driving direction of the limiting pin plate 111 is perpendicular to the driving direction of the first sliding drive device 110. By setting the limiting pin plate 111, the stroke of the cylinder rod 1101 can be limited to avoid the first sliding drive device 110 from retracting during use and causing molding errors, thus ensuring the consistency of the overall wall thickness of the formed blank.

[0022] A positioning groove 13 is provided on the outer side of the movement path of the cylinder rod 1101. One end of the positioning groove 13 is fixed in the frame 1, and the other end of the positioning groove 13 is fixed with a sliding groove 131. The limiting pin plate 111 is slidably connected in the sliding groove 131. A proximity sensor 14 is provided on one side of the sliding groove 131. In this embodiment, two proximity sensors 14 are provided, which are respectively provided at both ends of one side of the sliding groove 131. A sensing arm 141 is provided on the side of the limiting pin plate 111 corresponding to the proximity sensor 14. The proximity sensor 14 detects the position status of the limiting pin plate 111 by the sensing arm 141 approaching the proximity sensor 14.
