Description

Technical Field

[0001] The invention belongs to the technical field of forging processing equipment, in particular to a large-scale multi-station radial and axial automatic ring rolling machine. Background Art

[0002] Ring rolling mill is a steel rolling equipment used for rolling medium and thick steel plates. Ring rolling mill consists of a working machine base and a transmission device. The working machine base mainly includes a rolling mill frame, a roll system, a balancing system, a press-down device and a roll changing device. The transmission device consists of a large motor and a reducer. Due to the development of motor manufacturing technology, modern ring rolling mills are usually driven directly by motors.

[0003] As the market's requirements for material utilization and part precision continue to increase, high utilization, high precision, high efficiency, low loss and automation have become the development direction of the forging field. The existing ring rolling mill can no longer meet the market demand and future development direction.

[0004] The existing ring rolling mill has the following defects:

[0005] 1. When processing rings, the existing ring rolling machine can only process the inner hole, outer diameter or end face at a single station. After the processing is completed, the ring rolling parts need to be replaced, which is time-consuming and labor-intensive, and has low production efficiency;

[0006] 2. Since the rings have burrs at the processing position after being processed by the ring rolling machine, the rings cannot be polished and can only be polished manually, resulting in uneven polishing of the rings and increasing the labor intensity of the workers;

[0007] 3. The existing ring rolling mill has a low degree of automation and a low yield rate, resulting in low material utilization, high loss and low precision. Summary of the invention

[0052] Working principle:

[0053] 1. The invention is used in the rolling process of the rectangular ring 9:

[0054] Step 1: The radial motor 21 transmits the torque of the radial motor 21 to the main roller 68 through the small coupling 22, the radial reducer 24 and the large coupling 25, and the main roller 68 rotates counterclockwise;

[0055] Step 2: The upper cone roller motor 8101 and the lower cone roller motor 881 transmit the torque of the upper cone roller motor 8101 and the lower cone roller motor 881 to the upper cone roller 8105 and the lower cone roller 885 through the upper cone roller reducer 8103 and the lower cone roller reducer 883 respectively, and the upper cone roller 8105 and the lower cone roller 885 rotate in opposite directions;

[0056] Step 3: The ring is placed on the workbench 15. Driven by the lifting cylinder 75, the core roller 78 descends along the guide frame 73 and is inserted into the inner hole of the ring. The bottom is fixed on the lower crossbeam 79. During the descending process, the position of the core roller 78 is detected by the displacement sensor 74 in the lifting cylinder 75. When the target value is reached, the positioning cylinder 77 is actuated to position and lock the lifting frame 72.

[0057] Step 4: The upper crossbeam 76, the lower crossbeam 79 and the core roller 78 are pushed by the main oil cylinder 61 to move toward the main roller 68 along the upper tie rod 64 and the lower tie rod 610 to generate radial extrusion force to rotate and roll the ring; at the same time, the upper cone roller 8105 is driven by the rolling oil cylinder 84 to move along the movable bracket 83 to the lower cone roller 885 to axially extrude the end face of the ring;

[0058] Step 5: Through continuous rolling, the wall thickness of the ring is continuously reduced and the height is continuously reduced. The double-station axial rolling component 8 is driven by the follower cylinder 811 to retreat along the guide rail 17 in the guide rail plate 13 as the outer diameter of the ring increases. During the rolling process, the holding roller 33 is driven by the arm cylinder 31 to always contact the ring 9, so as to keep the rolling process stable and make the ring 9 bend and deform.

[0059] Step 6: When the outer diameter and height of the ring 9 reach the set values ​​at the same time, the core roller 78, the main rolling roller 68, the upper cone roller 8105 and the holding roller 33 return to the initial position at the same time.

[0060] The rolling of the rectangular ring 9 is completed through the above steps.

[0061] 2. The present invention is used for the rolling process of the inner diameter special-shaped contoured ring 9:

[0062] Repeat the first to fifth steps of the rolling process of the rectangular ring 9. When the outer diameter of the ring 9 reaches the set value of the station change, the core roller 78 moves away from the ring 9 for a distance under the push of the main cylinder 61. Then, the core roller 68 continues to descend along the guide frame 73 under the drive of the lifting cylinder 66, so that the cylindrical working surface 781 of the core roller enters the working position. After reaching the position, the positioning cylinder 77 is actuated to position and lock the lifting frame 72 again; then repeat the fourth to sixth steps of the rolling process of the rectangular ring 9.

[0063] The rolling of the inner diameter special-shaped contoured ring 9 is completed through the above steps.

[0064] 3. The present invention is used for the rolling process of the outer diameter special-shaped contoured ring 9:

[0065] Repeat the first to fifth steps of the rolling process of the rectangular ring 9. When the outer diameter of the ring 9 reaches the set value of the station change, the main roller 68 rises along the guide rail in the main roller seat 65 driven by the lifting cylinder 73, so that the main roller profiled working surface 682 enters the working position, and is positioned and locked by the lifting cylinder 75 after reaching the position; then repeat the fourth to sixth steps of the rolling process of the rectangular ring 9.

[0066] The rolling of the outer diameter special-shaped contoured ring 9 is completed through the above steps.

[0067] 4. The present invention is used for the rolling process of the end face special-shaped profiling ring 9:

[0068] Repeat the first to fifth steps of the rolling process of the rectangular ring 9. When the outer diameter of the ring 9 reaches the set value of the station change, the upper conical roller 8105, driven by the rolling cylinder 84 and the balancing cylinder 85, rises 50 mm along the guide rail in the movable bracket 83; then, it moves forward in the direction of the main rolling roller 68 under the push of the follower cylinder 811, so that the conical roller truncated table working surface 81051 enters the working position; finally, continue to repeat the fourth to sixth steps of the rolling process of the rectangular ring 9.

[0069] The rolling of the end face special-shaped contoured ring 9 is completed through the above steps.
