Description

Technical Field

[0001] This utility model relates to the field of ring rolling technology, specifically an automatic loading and unloading structure for a ring rolling machine. Background Technology

[0002] A ring rolling mill is a type of machining equipment used for extruding and plastically deforming ring-shaped parts. It mainly uses a mandrel and extrusion rollers on the equipment to extrude the inner and outer walls of the ring-shaped billet, while simultaneously driving the billet to rotate, thereby achieving comprehensive extrusion processing of the billet. The wall thickness of the billet gradually decreases, and the diameter of the billet gradually increases until the billet reaches the specified size.

[0003] When using a ring rolling mill, workers typically transfer the raw material, which is usually at a high temperature. Manual loading and unloading can easily cause burns to workers, posing a safety hazard. Furthermore, prolonged work in such a high-temperature environment can harm workers' health. Additionally, manual loading and unloading is labor-intensive and inefficient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic loading and unloading structure for a ring rolling mill, thereby solving the problems mentioned in the background section.

[0012] Preferably, the spray head is connected to the spray hose opening.

[0013] Compared with the prior art, this utility model provides an automatic loading and unloading structure for a ring rolling mill, which has the following beneficial effects:

[0014] 1. This ring rolling machine uses an automatic loading and unloading structure. First, after the machine is started, the loading roller begins to rotate, sending the rolling ring to the rolling ring table. After the rolling ring reaches the rolling ring table, the first limiting roller rotates to push the rolling ring below the lifting limiting rod. Then, the lifting limiting rod descends and inserts into the middle of the rolling ring. When processing the rolling ring, the first and second limiting rollers can be controlled to move to both sides of the rolling ring to prevent the rolling ring from shifting during processing and causing accidents, effectively improving the safety of processing. Then, the size of the rolling ring is adjusted by moving the rolling head, and the rolling head is moved to roll the rolling ring. The fixed rolling head rotates below the rolling ring to assist the moving rolling head in processing the rolling ring.

[0015] 2. This ring rolling machine uses an automatic loading and unloading structure. After processing, the rolling head is removed and the spray head is controlled to spray cooling water to cool the rolling ring. After cooling, the rolling ring is moved, which can effectively prevent the finished rolling ring from deforming. This not only reduces the defect rate of processing, but also reduces the cost of processing defective products in the production of enterprises. After the rolling ring is cooled, the lifting limit rod will move along the direction of the moving slide, driving the rolling ring to the upper side of the unloading roller, and moving the rolling ring to the unloading position.

[0024] Furthermore, a connecting rod 601 is fixedly installed at the telescopic end of the hydraulic rod 6, and a movable compaction head 7 is fixedly installed at the end of the connecting rod 601 away from the hydraulic rod 6.

[0025] Through the above technical solution, the size of the movable rolling head 7 can be set according to the required processing, so that the movable rolling head 7 stops descending when it moves to the set position during operation, so that the size of the rolling ring 10 is consistent with the preset.

[0026] Furthermore, the mobile compaction head 7 includes a fixed base 701, and a compaction head 702 is fixedly installed on the left side of the fixed base 701. The fixed compaction head 8 includes a fixed base 801, and a compaction head 802 is fixedly installed on the left side of the fixed base 801.

[0027] Through the above technical solution, the size of the grinding ring 10 is adjusted by moving the rolling head 7, the rolling head 7 is moved to roll the grinding ring 10, and the fixed rolling head 8 is rotated below the grinding ring 10 to assist the moving rolling head 7 in processing the grinding ring 10.

[0028] Furthermore, the lifting limit rod 9 includes a movable slider 901, a hydraulic rod 902 is fixedly installed on the bottom surface of the movable slider 901, a rotating roller 903 is fixedly installed on the telescopic end of the hydraulic rod 902, and a limit rod 904 is fixedly installed on the bottom surface of the rotating roller 903.

[0029] With the above technical solution, after the grinding ring 10 reaches the grinding ring table 3 through the feeding roller 4, the limiting roller 11 pushes the grinding ring 10 to below the lifting limiting rod 9. After the grinding ring 10 reaches below the lifting limiting rod 9, the lifting limiting rod 9 begins to descend and inserts into the middle of the grinding ring 10, and the equipment begins to process the grinding ring 10.

[0030] Furthermore, the limiting roller 11 includes a connecting plate 1103, a turntable 1102 is fixedly installed on the top surface of the connecting plate 1103, and a roller cylinder 1101 is fixedly installed on the bottom surface of the connecting plate 1103 at the end away from the turntable 1102.

[0033] The above technical solution allows for the connection of a hose to add cooling water. After processing, the spray head 13 is controlled to spray cooling water onto the grinding ring 10. When the temperature drops rapidly, the lifting limit rod 9 moves the grinding ring 10 onto the feeding roller 5, which can prevent deformation.

[0034] Working principle: After the machine is started, the feeding roller 4 begins to rotate, sending the grinding ring 10 to the grinding ring table 3. After the grinding ring 10 reaches the grinding ring table 3, the limiting roller 11 rotates to push the grinding ring 10 below the lifting limit rod 9. Then the lifting limit rod 9 descends and inserts into the middle of the grinding ring 10. Subsequently, the rolling head 7 is moved to adjust its position and begins to roll the grinding ring 10. After the rolling head is removed, the spray head 13 is controlled to spray cooling water to cool the grinding ring 10. After the grinding ring 10 has cooled slightly, the lifting limit rod 9 will move along the direction of the moving groove 101, bringing the grinding ring 10 to the upper side of the unloading roller 5 and moving the grinding ring 10 to the unloading position.
