[0019] The present invention also discloses a method for using the forging equipment for stainless steel ring forgings, comprising the following steps:

[0020] S1: During operation, the heated stainless steel ring blank is sleeved on the outer circumference of the core roller body, and then the drive motor, the first hydraulic cylinder and the second hydraulic cylinder are started. The drive motor drives the main roller body to rotate, so that the main roller body rolls the stainless steel ring, and the diameter of the blank is continuously increased when the first hydraulic cylinder is gradually extended. During this process, the core roller body is squeezed by the stainless steel ring and rotates with the stainless steel ring. The second hydraulic cylinder synchronously drives the centering roller body connected to the swing seat to abut against the stainless steel ring. The infrared temperature sensor monitors the temperature of the stainless steel ring during processing. When it is detected that the temperature of the stainless steel ring drops below the stainless steel processing temperature range, the flame heating nozzle continues to heat the stainless steel ring.

[0021] S2: After the ring rolling roller group has finished rolling the stainless steel ring placed on the core roller body, the staff will place another stainless steel ring to be rolled on the force plate. At this time, because the plug rod is plugged into the plug hole, the plug cannot be removed from the slot, the second and third pull ropes cannot be pulled and reeled, the force plate cannot drive the rotating rod to rotate, the worm cannot mesh with the worm wheel for transmission, and the stainless steel ring is placed on the force plate and is restricted from sliding down by the L-shaped baffle;

[0022] S3: Then the staff controls the first hydraulic cylinder and the second hydraulic cylinder to work, so that the piston rod of the first hydraulic cylinder drives the mounting seat to move upward, and then the mounting seat drives the main roller body away from the core roller body, and the piston rod of the second hydraulic cylinder drives the centering roller body away from the core roller body through the swing seat;

[0023] When the mounting seat moves upward, it drives the insertion rod upward, so that the insertion rod gradually moves toward the outside of the plug hole. When the mounting seat moves upward, the first pull rope applies tension to the slide seat, and the slide seat drives the support plate to slide in the sliding groove. The fourth elastic element is stretched until the support plate moves to the loading seat, and the end of the loading seat away from the vertical plate is inserted into the mounting groove of the support plate. The support plate temporarily supports and limits one end of the core roller part, and at this time, the insertion rod at the bottom of the mounting seat is completely moved out of the plug hole;

[0024] S4: After the plug is no longer restricted in movement, the stainless steel ring to be rolled on the force plate presses down on the force plate, and the force plate drives the rotating rod to rotate relative to the loading seat. When the rotating rod rotates, the outer worm gear meshes with the worm wheel in the loading seat, and when the worm wheel rotates, the main bevel gear is driven to mesh with the secondary bevel gear on the rotating rod through the rotating ring. The rotating rod drives the reel to rotate, so that the reel applies tension to the second pull rope, and the second pull rope applies tension to the positioning block. The positioning block shrinks in the movable groove, and then the positioning block transmits the tension to the plug, and the plug drives the core roller body to shrink into the upper material seat. The plug and the core roller body no longer support the stainless steel ring that has been processed. The stainless steel ring that has been processed automatically falls into the guide groove and rolls along the guide groove to the cooling zone for cooling;

[0025] As the rotating rod drives the reel to rotate, the reel simultaneously reels the third pull rope, and the third pull rope applies tension to the L-shaped baffle plate, so that the L-shaped baffle plate moves relative to the force plate, and the L-shaped baffle plate no longer limits the stainless steel ring on the force plate, and the stainless steel ring to be rolled slides down along the inclined force plate;

[0026] S5: The stainless steel ring to be rolled moves from the force plate to the slow-slip conical surface, and its sliding speed slows down. After the force plate is no longer pressed down by the stainless steel ring to be rolled, the force plate resets and moves upward, so that the reel releases the second and third pull ropes respectively, so that the plug is re-inserted into the slot of the vertical plate. During the process of the plug being inserted into the slot, the extrusion slope of the positioning block is squeezed by the inner wall of the slot, and the positioning block shrinks in the movable groove until the end of the plug abuts against the inner wall of the slot. At this time, the positioning block enters the annular groove under the elastic force of the first elastic element, and the position of the plug and the vertical plate is restricted. As the stainless steel ring to be rolled continues to slide down, the stainless steel ring to be rolled moves from the slow-slip conical surface to the core roller body, completing the placement of the stainless steel ring to be rolled;

[0027] S6: Then the first hydraulic cylinder and the second hydraulic cylinder are controlled to work, the second hydraulic cylinder drives the centering roller body connected to the swing seat to abut against the stainless steel ring, the first hydraulic cylinder drives the mounting seat to move downward through the piston rod, and the mounting seat drives the main roller body connected thereto to move downward, so that the main roller body abuts against the top of the stainless steel ring, and then the driving motor is controlled to operate, so that the ring rolling roller group rolls the stainless steel ring;

[0028] When the mounting seat moves downward, the insertion rod is inserted into the socket of the plug to realize the positioning installation of the plug. When the mounting seat moves downward, the first pull rope is no longer pulled, and the slide is reset under the elastic force of the fourth elastic element, so that the slide drives the support plate away from the loading seat, preparing for the placement of another stainless steel ring to be rolled.

[0029] Compared with the prior art, the present invention provides a forging device for stainless steel ring forgings and a method for using the same, which have the following beneficial effects:

[0030] 1. The forging equipment and the use method of the stainless steel ring forging realize automatic unloading of the stainless steel ring that has completed the ring rolling work when the stainless steel ring to be rolled is loaded, thereby reducing the waiting time for loading and unloading after the ring processing is completed, realizing rapid and continuous processing, and greatly improving the working efficiency of the forging equipment;

[0031] 2. The forging equipment and the use method of the stainless steel ring forging limit the plug by the insertion rod, so that the reel cannot reel in the third pull rope and the second pull rope, thereby limiting the force plate and the stainless steel ring to be rolled placed on the force plate, to avoid the force plate directly moving downward when the stainless steel ring is placed on the force plate, so that the reel reels in the third pull rope and the second pull rope, resulting in the direct separation of the core roller part and the vertical plate, making the structure unstable. Only after the stainless steel ring to be rolled is placed on the force plate, the first hydraulic cylinder is controlled to operate, the insertion rod is moved out of the plug socket, and the first pull rope drives the support plate to move toward the core roller part through the slide seat, so that the support plate supports one end of the core roller part, and then the core roller part can be separated from the vertical plate, which is convenient for the automatic unloading of the stainless steel ring that has completed the ring rolling work and the automatic loading of the stainless steel ring to be rolled.

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] Example 1: Reference Figure 1-7 A forging device for a stainless steel ring forging comprises a workbench 1 and a vertical plate 2 vertically arranged on the workbench 1, and further comprises:

[0047] The ring rolling roller assembly includes a main roller portion 3, a core roller portion 4 and a centering roller portion 5, and is used to position the stainless steel ring 6;

[0048] A heat preservation member connected to the centering roller portion 5, the heat preservation member comprises a U-shaped plate 7, a flame heating nozzle 701 disposed between the inner walls of both sides of the U-shaped plate 7, and an infrared temperature sensor 702 for monitoring the temperature of the stainless steel ring 6;

[0049] The core roller part 4 is detachably connected to the vertical plate 2, and the core roller part 4 includes a plug 401 plugged into the vertical plate 2, a core roller body 402 rotatably connected to the plug 401, and a loading seat 403 movably connected to an end of the core roller body 402 away from the plug 401;

[0050] An auxiliary support assembly for temporarily supporting the core roller portion 4 is slidably connected inside the workbench 1 , and a first pull rope 8 is provided between the auxiliary support assembly and the main roller portion 3 .

[0051] Specifically, during operation, the heated stainless steel ring 6 blank is sleeved on the core roller body 402 between the loading seat 403 and the plug 401, and the main roller part 3 cooperates with the centering roller part 5 to drive the stainless steel ring 6 at the core roller part 4 to move. During this period, the infrared temperature sensor 702 monitors the temperature of the stainless steel ring 6 during processing. When it is detected that the temperature of the stainless steel ring 6 drops below the stainless steel processing temperature range, the flame heating nozzle 701 continues to heat the stainless steel ring 6 to avoid a large temperature difference between the inner and outer surfaces of the blank of the stainless steel ring 6 during ring rolling, thereby improving the uniformity of deformation during ring rolling and better avoiding the generation of cracks during ring rolling. After the stainless steel ring 6 on the core roller part 4 is rolled, the stainless steel ring 6 that has completed the ring rolling work is automatically unloaded when the stainless steel ring 6 to be rolled is loaded;

[0052] The present application only places the stainless steel ring 6 to be rolled on the loading seat 403, and performs other work in the existing manner. After the ring rolling is completed, the main roller part and the centering roller part are controlled to reset, so that when the stainless steel ring 6 to be rolled is loaded, the stainless steel ring 6 that has completed the ring rolling work can be automatically unloaded. Compared with the prior art, after the ring rolling process is completed, the main roller part and the centering roller part are controlled to reset, and then the stainless steel ring 6 placed on the core roller part is manually taken out, and then the stainless steel ring 6 to be rolled is manually placed on the core roller part 4, which reduces the waiting time for replacement when loading and unloading after the ring processing is completed, realizes fast and continuous processing, and greatly improves the working efficiency of the forging equipment.

[0053] Example 2: Reference Figure 1-7, a forging equipment for stainless steel ring forgings, based on Example 1, further, the main roller part 3 includes a first support plate 301 fixed on the vertical plate 2, a first hydraulic cylinder 302 fixedly connected to the first support plate 301, a mounting seat 303 connected to the piston rod of the first hydraulic cylinder 302, a driving motor 304 arranged in the mounting seat 303 and a main roller body 305 connected to the output shaft of the driving motor 304.

[0054] Furthermore, the centering roller portion 5 includes a second support plate 501 fixed on the vertical plate 2, a second hydraulic cylinder 502 fixedly connected to the second support plate 501, and a swing seat 503 movably connected to the piston rod of the second hydraulic cylinder 502, a fixed rod 504 is arranged between the swing seat 503 and the vertical plate 2, the U-shaped plate 7 is fixedly connected to the swing seat 503, and a centering roller body 505 is movably connected inside the U-shaped plate 7.

[0055] Specifically, during operation, the heated stainless steel ring 6 blank is sleeved on the outer circumferential surface of the core roller body 402, and then the drive motor 304, the first hydraulic cylinder 302 and the second hydraulic cylinder 502 are started. The drive motor 304 drives the main roller body 305 to rotate, so that the main roller body 305 rolls the stainless steel ring 6, and the diameter of the blank is continuously increased when the first hydraulic cylinder 302 gradually extends. In this process, the core roller body 402 is squeezed by the stainless steel ring 6 and rotates with the stainless steel ring 6. The second hydraulic cylinder 502 synchronously drives the centering roller body 505 connected to the swing seat 503 to abut against the stainless steel ring 6, so that the various components of the ring rolling roller group work together to realize the ring rolling of the stainless steel ring 6.

[0056] Example 3: Reference Figure 5-8 , a forging device for stainless steel annular forgings, based on Example 2, further, a plurality of movable grooves 9 are opened in the plug 401, a positioning block 901 is slidably connected in the movable groove 9, a first elastic element 902 is arranged between the positioning block 901 and the inner wall of the movable groove 9, an extrusion slope is opened on the side of the positioning block 901 away from the core roller part 4, a slot 201 matching with the plug 401 is opened on the vertical plate 2, and an annular groove 2011 matching with the positioning block 901 is opened on the inner wall of the slot 201.

[0057] Specifically, when the core roller part 4 is connected to the vertical plate 2, the plug 401 of the core roller part 4 is inserted into the slot 201, and the extrusion slope of the positioning block 901 on the plug 401 is forced to shrink into the movable groove 9. After the plug 401 continues to penetrate into the slot 201, the positioning block 901 is aligned with the annular groove 2011, and the positioning block 901 is reset under the elastic force of the first elastic element 902, so that the positioning block 901 limits the plug 401 in the vertical plate 2 to prevent the core roller part 4 from falling when working.

[0058] Example 4: Reference Figure 7 , Figure 8 and Fig.11 A forging device for a stainless steel annular forging. Based on Example 3, further, a plug rod 3031 is fixedly provided at the bottom of a mounting seat 303, and a plug 401 is evenly provided with a plurality of plug holes 4011 matching with the plug rod 3031 in a circumferential manner.

[0059] Specifically, by providing a socket 4011 at the end of the plug 401, when the main roller portion 3 moves downward, the downward movement of the mounting seat 303 can drive the insertion rod 3031 to be inserted into the socket 4011, thereby further limiting the plug 401; at the same time, a plurality of sockets 4011 are provided, and are evenly distributed in a circle at the end of the plug 401, so that the plug 401 can penetrate into the slot 201 at any angle, so that the insertion rod 3031 can be directly inserted into the socket 4011 when the mounting seat 303 moves downward.

[0060] Example 5: Reference Figure 1-11 , a forging equipment for stainless steel annular forgings, based on Example 4, further, a working groove 10 is opened in the loading seat 403, the core roller body 402 slides in the working groove 10, and the end of the core roller body 402 away from the plug 401 is rotatably connected to a rotating plate 1001, and a second elastic element 1002 is arranged between the rotating plate 1001 and the inner wall of the working groove 10.

[0061] Furthermore, the loading seat 403 is provided with a plurality of rotating rods 11 evenly distributed on the circumference, each rotating rod 11 is fixedly provided with a force plate 111, and a torsion spring is sleeved on the outer side of the rotating rod 11, whose two ends are respectively connected to the loading seat 403 and the force plate 111, and a worm 112 is fixedly provided on the rotating rod 11, and a worm wheel 113 which is rotatably connected to the loading seat 403 and meshed with the worm 112 is fixedly provided on the worm wheel 113, and a main bevel gear 1132 is provided on the rotating ring 1131, and a rotating rod 12 is rotatably connected to the loading seat 403, and a secondary bevel gear 121 which is meshed with the main bevel gear 1132 is provided on the rotating ring 1131, and a reel 122 is provided on the rotating rod 12, and a second pull rope 123 is wound around the reel 122, and the end of the second pull rope 123 away from the reel 122 passes through the loading seat 403 and the core roller body 402 in sequence and is connected to the positioning block 901.

[0062] Furthermore, a slow-sliding conical surface is arranged between one end of the loading seat 403 and the force-bearing plate 111, an L-shaped baffle plate 13 is slidably connected to the force-bearing plate 111, a third elastic element 131 is arranged between the L-shaped baffle plate 13 and the bottom wall of the force-bearing plate 111, a third pull rope 132 is fixed on the L-shaped baffle plate 13, and one end of the third pull rope 132 away from the L-shaped baffle plate 13 is connected to the reel 122.

[0063] Furthermore, the auxiliary support assembly includes a slide 14 sliding in the workbench 1 and a support plate 141 fixed on the top of the slide 14, the support plate 141 is provided with a mounting groove 1411 matching the loading seat 403, the workbench 1 is provided with a sliding groove 15 for the slide 14 to slide, a fourth elastic element 151 is provided between the inner wall of the sliding groove 15 and the slide 14, the two ends of the first pull rope 8 are respectively connected to the slide 14 and the mounting seat 303, and a material guide groove 101 is also provided on the top of the workbench 1.

[0064] Specifically, after the ring rolling roller group has finished rolling the stainless steel ring 6 placed on the core roller body 402, the staff will place another stainless steel ring 6 to be rolled on the force plate 111. It should be noted that there are multiple force plates 111 on the outer side of the loading seat 403, so that the force plate 111 can receive the stainless steel ring 6 to be rolled no matter which position the loading seat 403 is rotated. At this time, because the plug rod 3031 is plugged into the socket 4011 of the plug 401, the plug 401 cannot be moved out of the slot 201, the second pull rope 123 and the third pull rope 132 cannot be pulled and reeled, the force plate 111 cannot drive the rotating rod 11 to rotate, the worm 112 cannot mesh with the worm wheel 113 for transmission, and the stainless steel ring 6 is placed on the force plate 111 and is restricted from sliding down by the L-shaped baffle 13;

[0065] Then the staff controls the first hydraulic cylinder 302 and the second hydraulic cylinder 502 to work, so that the piston rod of the first hydraulic cylinder 302 drives the mounting seat 303 to move upward, and then the mounting seat 303 drives the main roller body 305 away from the core roller body 402, and the piston rod of the second hydraulic cylinder 502 drives the centering roller body 505 away from the core roller body 402 through the swing seat 503;

[0066] When the mounting seat 303 moves upward, it drives the insertion rod 3031 to move upward, so that the insertion rod 3031 gradually moves toward the outside of the insertion hole 4011. When the mounting seat 303 moves upward, the first pull rope 8 applies tension to the slide 14, and the slide 14 drives the support plate 141 to slide in the sliding groove 15. The fourth elastic element 151 is stretched until the support plate 141 moves to the loading seat 403, and the end of the loading seat 403 away from the vertical plate 2 is inserted into the mounting groove 1411 of the support plate 141. The support plate 141 temporarily supports and limits one end of the core roller part 4, and at this time, the bottom of the mounting seat 303 The insertion rod 3031 of the upper part is completely moved out of the insertion hole 4011 of the plug 401. It should be noted that the length of the loading seat 403 inserted into the installation groove 1411 is greater than the length of the plug 401 and the core roller body 402, so as to avoid the loading seat 403 and the support plate 141 from moving relative to each other when the subsequent plug 401 and the core roller body 402 are retracted into the working groove 10 of the upper material seat 403, so that the loading seat 403 placed between the vertical plate 2 and the support plate 141 falls from the installation groove 1411, affecting the subsequent automatic plug-in installation of the core roller part 4 on the vertical plate 2;

[0067] After the plug 401 is no longer restricted in movement, the stainless steel ring 6 to be rolled on the force plate 111 presses down on the force plate 111, and the force plate 111 drives the rotating rod 11 to rotate relative to the loading seat 403. When the rotating rod 11 rotates, the outer worm 112 engages with the worm wheel 113 in the loading seat 403 for transmission. When the worm wheel 113 rotates, the main bevel gear 1132 is driven to engage with the secondary bevel gear 121 on the rotating rod 12 through the rotating ring 1131. The rotating rod 12 drives the reel 122 to rotate, thereby causing the reel 122 to rotate relative to the first The second pull rope 123 applies a pulling force, and the second pull rope 123 applies a pulling force to the positioning block 901, and the positioning block 901 shrinks in the movable groove 9, and then the positioning block 901 transmits the pulling force to the plug 401, and the plug 401 drives the core roller body 402 to shrink into the upper material seat 403, and the plug 401 and the core roller body 402 no longer support the stainless steel ring 6 that has been processed, and the stainless steel ring 6 that has been processed automatically falls into the guide groove 101, and rolls along the guide groove 101 to the cooling zone for cooling;

[0068] As the rotating rod 12 drives the reel 122 to rotate, the reel 122 simultaneously reels the third pull rope 132, and the third pull rope 132 applies tension to the L-shaped baffle 13, so that the L-shaped baffle 13 moves relative to the force-bearing plate 111, and the L-shaped baffle 13 no longer limits the stainless steel ring 6 on the force-bearing plate 111, and the stainless steel ring 6 to be rolled slides down along the inclined force-bearing plate 111;

[0069] After the stainless steel ring 6 to be rolled moves from the force plate 111 to the slow-slip conical surface, the sliding speed slows down. After the force plate 111 is no longer pressed down by the stainless steel ring 6 to be rolled, the force plate 111 resets and moves upward, so that the reel 122 releases the second pull rope 123 and the third pull rope 132 respectively, so that the plug 401 is re-inserted into the slot 201 of the vertical plate 2. During the process of the plug 401 being inserted into the slot 201, the extrusion slope of the positioning block 901 is squeezed by the inner wall of the slot 201, and the positioning block 901 shrinks in the movable groove 9 until the end of the plug 401 abuts against the inner wall of the slot 201. At this time, the positioning block 901 enters the annular groove 2011 under the elastic force of the first elastic element 902, and the position of the plug 401 and the vertical plate 2 is restricted. As the stainless steel ring 6 to be rolled continues to slide down, the stainless steel ring 6 to be rolled moves from the slow-slip conical surface to the core roller body 402, completing the placement of the stainless steel ring 6 to be rolled.

[0070] Then, the first hydraulic cylinder 302 and the second hydraulic cylinder 502 are controlled to work, the second hydraulic cylinder 502 drives the centering roller body 505 connected to the swing seat 503 to abut against the stainless steel ring 6, the first hydraulic cylinder 302 drives the mounting seat 303 to move downward through the piston rod, and the mounting seat 303 drives the main roller body 305 connected thereto to move downward, so that the main roller body 305 abuts against the top of the stainless steel ring 6, and then the driving motor 304 is controlled to operate, so that the ring rolling roller group performs the ring rolling work on the stainless steel ring 6;

[0071] When the mounting seat 303 moves downward, the insertion rod 3031 is inserted into the socket 4011 of the plug 401 to achieve the positioning installation of the plug 401, and the first pull rope 8 is no longer pulled when the mounting seat 303 moves downward. The slide 14 is reset under the elastic force of the fourth elastic element 151, so that the slide 14 drives the support plate 141 away from the loading seat 403, preparing for the subsequent placement of another stainless steel ring 6 to be rolled.

[0072] The present invention also discloses a method for using a forging device for a stainless steel annular forging, comprising the following steps:

[0073] S1: During operation, the heated stainless steel ring 6 blank is sleeved on the outer circumference of the core roller body 402, and then the drive motor 304, the first hydraulic cylinder 302 and the second hydraulic cylinder 502 are started. The drive motor 304 drives the main roller body 305 to rotate, so that the main roller body 305 rolls the stainless steel ring 6, and the diameter of the blank is continuously increased when the first hydraulic cylinder 302 gradually extends. In this process, the core roller body 402 is squeezed by the stainless steel ring 6 and rotates with the stainless steel ring 6. The second hydraulic cylinder 502 synchronously drives the centering roller body 505 connected to the swing seat 503 to abut against the stainless steel ring 6. The infrared temperature sensor 702 monitors the temperature of the stainless steel ring 6 during processing. When it is detected that the temperature of the stainless steel ring 6 drops below the stainless steel processing temperature range, the flame heating nozzle 701 continues to heat the stainless steel ring 6.

[0074] S2: After the ring rolling roller group has finished rolling the stainless steel ring 6 placed on the core roller body 402, the staff places another stainless steel ring 6 to be rolled on the force plate 111. At this time, because the plug rod 3031 is plugged into the plug hole 4011 of the plug 401, the plug 401 cannot be moved out of the slot 201, the second pull rope 123 and the third pull rope 132 cannot be pulled and reeled, the force plate 111 cannot drive the rotating rod 11 to rotate, the worm 112 cannot mesh with the worm wheel 113 for transmission, and the stainless steel ring 6 is placed on the force plate 111 and is restricted from sliding down by the L-shaped baffle 13;

[0075] S3: Then the staff controls the first hydraulic cylinder 302 and the second hydraulic cylinder 502 to work, so that the piston rod of the first hydraulic cylinder 302 drives the mounting seat 303 to move upward, and then the mounting seat 303 drives the main roller body 305 away from the core roller body 402, and the piston rod of the second hydraulic cylinder 502 drives the centering roller body 505 away from the core roller body 402 through the swing seat 503;

[0076] When the mounting seat 303 moves upward, it drives the insertion rod 3031 to move upward, so that the insertion rod 3031 gradually moves toward the outside of the insertion hole 4011. When the mounting seat 303 moves upward, the first pull rope 8 applies tension to the slide 14, and the slide 14 drives the support plate 141 to slide in the sliding groove 15, and the fourth elastic element 151 is stretched until the support plate 141 moves to the loading seat 403, and the end of the loading seat 403 away from the vertical plate 2 is inserted into the mounting groove 1411 of the support plate 141, and the support plate 141 temporarily supports and limits one end of the core roller part 4, and at this time, the insertion rod 3031 at the bottom of the mounting seat 303 is completely moved out of the insertion hole 4011 of the plug 401;

[0077] S4: After the plug 401 is no longer restricted in movement, the stainless steel ring 6 to be rolled on the force plate 111 presses down on the force plate 111, and the force plate 111 drives the rotating rod 11 to rotate relative to the loading seat 403. When the rotating rod 11 rotates, the outer worm 112 engages with the worm wheel 113 in the loading seat 403 for transmission. When the worm wheel 113 rotates, the main bevel gear 1132 is driven to engage with the secondary bevel gear 121 on the rotating rod 12 through the rotating ring 1131. The rotating rod 12 drives the reel 122 to rotate, thereby causing the reel 122 to rotate. Apply tension to the second pull rope 123, and the second pull rope 123 applies tension to the positioning block 901, and the positioning block 901 shrinks in the movable groove 9, and then the positioning block 901 transmits the tension to the plug 401, and the plug 401 drives the core roller body 402 to shrink into the upper material seat 403, and the plug 401 and the core roller body 402 no longer support the stainless steel ring 6 that has been processed, and the stainless steel ring 6 that has been processed automatically falls into the guide groove 101, and rolls along the guide groove 101 to the cooling zone for cooling;

[0078] As the rotating rod 12 drives the reel 122 to rotate, the reel 122 simultaneously reels the third pull rope 132, and the third pull rope 132 applies tension to the L-shaped baffle 13, so that the L-shaped baffle 13 moves relative to the force-bearing plate 111, and the L-shaped baffle 13 no longer limits the stainless steel ring 6 on the force-bearing plate 111, and the stainless steel ring 6 to be rolled slides down along the inclined force-bearing plate 111;

[0079] S5: After the stainless steel ring 6 to be rolled moves from the force plate 111 to the slow-slip conical surface, the sliding speed slows down. After the force plate 111 is no longer pressed down by the stainless steel ring 6 to be rolled, the force plate 111 resets and moves upward, so that the reel 122 releases the second pull rope 123 and the third pull rope 132 respectively, so that the plug 401 is re-inserted into the slot 201 of the vertical plate 2. During the process of the plug 401 being inserted into the slot 201, the extrusion slope of the positioning block 901 is squeezed by the inner wall of the slot 201, and the positioning block 901 shrinks in the movable groove 9 until the end of the plug 401 abuts against the inner wall of the slot 201. At this time, the positioning block 901 enters the annular groove 2011 under the elastic force of the first elastic element 902, and the position of the plug 401 and the vertical plate 2 is restricted. As the stainless steel ring 6 to be rolled continues to slide down, the stainless steel ring 6 to be rolled moves from the slow-slip conical surface to the core roller body 402, completing the placement of the stainless steel ring 6 to be rolled.

[0080] S6: Then the first hydraulic cylinder 302 and the second hydraulic cylinder 502 are controlled to work, the second hydraulic cylinder 502 drives the centering roller body 505 connected to the swing seat 503 to abut against the stainless steel ring 6, the first hydraulic cylinder 302 drives the mounting seat 303 to move downward through the piston rod, and the mounting seat 303 drives the main roller body 305 connected thereto to move downward, so that the main roller body 305 abuts against the top of the stainless steel ring 6, and then the driving motor 304 is controlled to operate, so that the ring rolling roller group performs the ring rolling work on the stainless steel ring 6;

[0081] When the mounting seat 303 moves downward, the insertion rod 3031 is inserted into the socket 4011 of the plug 401 to achieve the positioning installation of the plug 401, and the first pull rope 8 is no longer pulled when the mounting seat 303 moves downward. The slide 14 is reset under the elastic force of the fourth elastic element 151, so that the slide 14 drives the support plate 141 away from the loading seat 403, preparing for the subsequent placement of another stainless steel ring 6 to be rolled.
