Description

Technical Field

[0001] The present invention relates to the technical field of forging and pressing, and particularly relates to a manufacturing device for rolling metal forgings. Background Art

[0002] The main working components and tools for causing continuous plastic deformation of metals on a rolling mill. The roll mainly consists of three parts: the roll body, the roll neck, and the shaft head. The roll body is the middle part of the roll that actually participates in rolling metals, and it has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the mill stand through the bearing housing and the screw-down device. The drive-end shaft head is connected to the gear housing through a coupling shaft to transmit the rotational torque of the motor to the roll. The rolls can be arranged in the form of two-high, three-high, four-high, or multi-high in the rolling mill stand.

[0003] For some metal forgings with special structures, grooved structures need to be designed on the rolls accordingly. However, during the process of rolling metal forgings and causing plastic deformation of the forgings, the forgings will generate and drop metal debris and slag due to fragmentation. These debris and slag are prone to accumulate and fill into the internal parts of each grooved structure, and adhere to the concave parts of the grooved structures. After the debris and slag cool down, they form blocky or flaky residues, which are difficult to clean and affect the continuous processing of the rolling equipment.

[0004] Therefore, in view of the above problems, a new type of rolling equipment can be designed to provide power through the lifting and rotation of the pressing roll, and control the timely cleaning of the residual waste slag remaining in the grooved structures to ensure the continuous working stability of the rolling equipment. Summary of the Invention

[0005] In order to overcome the problem that the metal debris generated due to fragmentation of the forgings is prone to accumulate and fill into the internal parts of each grooved structure and is difficult to clean after cooling and slagging.

[0016] The beneficial effects of the present invention: 1. The lifting assembly sends a signal command when lifting the rolling assembly, and cooperates with the inflatable assembly, linkage assembly and transmission assembly on the rolling assembly to drive the top ring to move in the rolling groove, and remove the slag remaining in the rolling groove in time. Compared with the original cleaning method, the cleaning is more timely, and the waste slag will not be difficult to remove after cooling and hardening, and no manual cleaning is required, saving labor input; 2. The lifting assembly is used to increase the power of the rolling assembly to control the operation of the flip assembly, driving the groove to flip between the metal forging transport track and the rolling assembly when cleaning the rolling groove, so as to prevent the cleaned waste slag from falling on the transport track and affecting the next operation; 3. By using the airbags arranged in the roller body and the air holes on the support tube, air flow is input into the groove while the top ring moves to clean the groove, which helps the hot air accumulated in the concave structure of the groove to flow away faster, thus playing an auxiliary heat dissipation effect and avoiding deformation and fracture caused by inconsistent thermal stress between the groove and the roller body during continuous use; 4. Through the locking assembly, the linkage assembly is limited during the normal operation of the roller body to prevent it from rotating with the roller body, so as to avoid the misalignment of the joint and the butt groove during cleaning, which will cause the power of the rolling assembly to be unable to be transmitted to the linkage assembly and the transmission assembly; 5. The conveyor belt and scraper plate arranged in the channel can scrape off the waste residue adhering to the conveyor belt, thus preventing the high-temperature waste residue from adhering to the channel and causing blockage of material discharge; 6. Through the cooperation of the wind blowing assembly and the turning assembly, when the groove is turned down into place, the wind blowing assembly can deliver air flow to the rolling groove to assist in cooling the waste slag remaining in the rolling groove, and also accelerate the heat dissipation of the rolling groove; 7. Through the cooperation of the wind blowing assembly and the turning assembly, when the trough is turned upward and reset, the wind blowing assembly can deliver air flow to the transmission belt to assist in removing fine residues between the belt plates of the transmission belt, so as to prevent the residues from falling onto the transport track after the trough is reset; 8. Through the cooperation of the transmission assembly and the ejection assembly, when there is a large amount of waste slag remaining in the rolling groove, the top block can be controlled to move together with the top ring, and the waste slag pushed together by the top ring can be pushed out of the rolling groove by the radial movement of the roller body, so as to avoid the waste slag being difficult to peel off due to the lateral pushing effect.

Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

The lifting component is used to drive the bench 301 and the roll component to move in the vertical direction. The input end of the roll component is connected to the output end of the driving component, and the driving component is used to drive the roll component to rotate. A rolling groove 305 is provided on the roll component. The input end of the transmission component is connected to the output end of the linkage component, and a top ring 907 is installed on the transmission component. The transmission component is used to drive the top ring 907 to move in the rolling groove 305. An airbag 10 is installed on the transmission component. When the top ring 907 moves in the rolling groove 305, gas flows out of or into the airbag 10; when the roll component moves in the H1 direction, the gas in the inflation component flows into the linkage component; when the roll component moves in the H2 direction, the gas in the linkage component flows into the inflation component; when the roll component moves in the H1 direction to a preset value M1, the input end of the linkage component is connected to the output end of the rolling component, and the locking component is disengaged from the linkage component; when the roll component moves in the H2 direction to a preset value M2, the input end of the linkage component is disengaged from the output end of the rolling component, and the locking component is connected to the linkage component; a flipping component is installed on the bench 301, and a channel 1105 is installed on the flipping component. When the roll component moves in the H1 direction, the flipping component drives the channel 1105 to rotate downward to below the rolling component; when the roll component moves in the H2 direction, the flipping component drives the channel 1105 to rotate upward to the upper side of the rolling component; a wind dust removal component is installed on the flipping component. When the channel 1105 rotates downward, the gas in the wind dust removal component flows to the rolling groove 305; when the channel 1105 rotates upward, the gas in the wind dust removal component flows to the channel 1105; the lifting component drives the roll component to move in the H1 direction. During this process, the inflation component inflates the linkage component and the locking component. At the same time, the flipping component drives the channel 1105 to flip downward, and the wind dust removal component outputs an air flow to the position of the rolling groove 305 for wind cooling. When the roll component moves to the preset value M1, the locking component releases the limit on the linkage component, and at the same time, the linkage component forms a transmission relationship with the rolling component, and the channel 1105 also flips to below the rolling component. When the driving component is started, the roll component is controlled to rotate, and at the same time, power is transmitted step by step through the linkage component and the transmission component to drive the top ring 907 to extend out of the rolling groove 305 for cleaning, and the waste residue cleaned down falls into the channel 1105.

When the roll assembly moves in the H2 direction and reaches the preset value M2, the second plunger 605 drives the push rod 607 to move away from the driving disc 308 until the docking head 608 is disengaged from the docking groove 309.The locking component includes a third air cavity 701 arranged in the roll body 302, a third plunger 702 movably connected in the third air cavity 701, a locking pin 703 fixedly installed on the third plunger 702, and a third return spring 704 with one end connected to the third plunger 702. The other end of the third return spring 704 is connected to the third air cavity 701. The third return spring 704 is used to drive the third plunger 702 to move within the third air cavity 701. The locking pin 703 is adapted to the locking hole 604. When the roll assembly moves in the H1 direction and reaches the preset value M1, the third plunger 702 drives the locking pin 703 away from the locking disc 603 until the locking pin 703 disengages from the locking hole 604. When the roll assembly moves in the H2 direction and reaches the preset value M2, the third plunger 702 drives the locking pin 703 close to the locking disc 603 until the locking pin 703 enters the locking hole 604.When the bench 301 moves along the H1 direction, the compression air hood 401 is compressed, so that the gas in the air hood 401 flows into the first air chamber 403 through the air delivery pipe 402, causing the first plunger 404 in the first air chamber 403 to move against the elastic force of the first return spring 405, and prompting the gas originally in the first air chamber 403 to flow into the second air chamber 601 and the third air chamber 701 through the exhaust pipe 406, the direct current pipe 501 and the shunt pipe 502 (the gas enters the second air chamber 601 through the direct current pipe 501 and enters the third air chamber 701 through the shunt pipe 502. In practical applications, the elastic force of the second return spring 606 is less than that of the third return spring 704. That is to say, the gas will preferentially flow into the second air chamber 601. After the second return spring 606 is stretched to a certain value, the gas will then enter the third air chamber 701 through the shunt pipe 502. An electric valve can also be set on the shunt pipe 502 to control), causing the second plunger 605 to drive the ejector rod 607 and the docking head 608 to move until the docking head 608 enters the docking groove 309, and then the third plunger 702 drives the locking pin 703 to disengage from the locking hole 604, releasing the limiting effect on the locking disc 603 (during the normal operation of the roll assembly for rolling metal forgings, it is easy for the second air chamber 601, the ejector rod 607 and the roll body 302 to fail to rotate synchronously due to unstable friction, resulting in the misalignment of the docking head 608 and the docking groove 309, so that the docking head 608 cannot accurately align with the docking groove 309 to form a transmission relationship during cleaning. Therefore, a locking assembly is needed to limit the locking disc 603). At this time, the roll assembly reaches the preset value M1. When the bench 301 moves along the H2 direction, the air hood 401 is stretched, and the gas in the first air chamber 403 flows into the air hood 401 through the air delivery pipe 402. Under the elastic force of the first return spring 405, the first plunger 404 moves in the first air chamber 403, and the gas in the second air chamber 601 and the third air chamber 701 flows back into the first air chamber 403. Under the action of the second return spring 606 and the third return spring 704, the second plunger 605 drives the ejector rod 607 and the docking head 608 to move away from the drive disc 308 until the docking head 608 separates from the docking groove 309, and the third plunger 702 drives the locking pin 703 to re-enter the locking hole 604, and once again limits the locking disc 603 to ensure that the second air chamber 601, the ejector rod 607 and the roll body 302 rotate synchronously during the rolling of metal.;

[0023] Please refer to Figures 1 - 5 、 Figures 7 - 8 、 Figures 10 - 11 and Figures 13 - 16, in this embodiment, the transmission assembly includes a first transmission bevel gear 801 movably connected to the roll body 302, several second transmission bevel gears 802, a transmission gear 803 mounted on the first transmission bevel gear 801 and the second transmission bevel gears 802, and a tooth chain 804 meshingly connected to several transmission gears 803. The first transmission bevel gear 801 meshes with the bevel gear seat 602, and the bevel gear seat 602 is used to drive the first transmission bevel gear 801 and the corresponding transmission gear 803 to rotate. The second transmission bevel gears 802 correspond to the rolling grooves 305 one by one. The transmission gear 803 and the tooth chain 804 on the first transmission bevel gear 801 are used to drive the remaining transmission gears 803 and the corresponding second transmission bevel gears 802 to rotate. The transmission assembly further includes a screw sleeve 901 movably connected inside the roll body 302, a third transmission bevel gear 902 mounted on the screw sleeve 901, a screw tube 903 threadedly connected to the screw sleeve 901, a slip ring 904 fixedly installed on the screw tube 903, a support tube 905 with one end fixedly connected to the slip ring 904, and air holes 906 opened on the support tube 905. A top ring 907 is installed at the other end of the support tube 905. The third transmission bevel gear 902 meshes with the corresponding second transmission bevel gear 802. The second transmission bevel gear 802 is used to drive the screw sleeve 901 and the third transmission bevel gear 902 to rotate. The screw sleeve 901 is used to drive the screw tube 903, the slip ring 904, and the top ring 907 to move along the axis direction of the roll body 302. One end of the airbag 10 is connected to the slip ring 904, and the other end is connected to the inner wall of the roll body 302. The airbag 10 is communicated with the support tube 905, and the gas in the support tube 905 flows out through the air holes 906. When the slip ring 904 approaches the corresponding screw sleeve 901, the airbag 10 is compressed, and the gas in the airbag 10 flows into the support tube 905. When the slip ring 904 moves away from the corresponding screw sleeve 901, the airbag 10 expands, and the gas in the support tube 905 flows into the airbag 10. Through the transmission effect of the bevel gear seat 602 and the first transmission bevel gear 801, and in cooperation with the transmission effect of the tooth chain 804 and the transmission gear 803, the rotating second air chamber 601 drives the second transmission bevel gear 802 to rotate, so that the third transmission bevel gear 902 and the screw sleeve 901 meshing with the second transmission bevel gear 802 rotate. The rotating screw sleeve 901 drives the screw tube 903 to move along the central axis direction of the roll body 302 through the thread transmission effect, driving the slip ring 904 and the support tube 905 to push the top ring 907 out of the side wall of the rolling groove 305 (the two top rings 907 in the same rolling groove 305 move towards each other), clearing the residual waste slag. At the same time, during the movement of the slip ring 904, it compresses the airbag 10, causing the gas in the airbag 10 to flow into the support tube 905 and be discharged through the air holes 906 on the support tube 905 extending into the rolling groove 305, providing air-cooled auxiliary heat dissipation around the rolling groove 305 (the hot air in the concave structure of the rolling groove 305 loses heat slowly, heat accumulates, and the heat dissipation is slower than that of the roll body 302. The thermal stress is different, and after long-term use, the part of the rolling groove 305 is prone to deformation and damage).

[0024] Please refer to Figures 1 - 6, in this embodiment, the flipping assembly includes a bracket 1101 with one end fixedly connected to the bench 301, a first driving spur gear 1102 movably connected to the other end of the bracket 1101, a rocker arm 1103 with one end movably connected to an eccentric position of the first driving spur gear 1102, and a lifting arm 1104 fixedly installed on the first driving spur gear 1102. The other end of the rocker arm 1103 is movably connected to the frame 1. A channel 1105 is fixedly installed on the lifting arm 1104. When the rolling assembly moves in the vertical direction, the rocker arm 1103 drives the first driving spur gear 1102, the lifting arm 1104, and the channel 1105 to rotate. A transmission belt 1106 and a scraper 1107 are installed in the channel 1105, and the scraper 1107 is arranged above the transmission belt 1106; the wind dust removal assembly includes a fourth air chamber 1201 installed on the lifting arm 1104, a fourth plunger 1202 movably connected in the fourth air chamber 1201, a second driving spur gear 1203 movably connected to the lifting arm 1104, a push-pull frame 1204 with one end movably connected to an eccentric position of the second driving spur gear 1203, a first air outlet nozzle 1205 installed on the scraper 1107, and a second air outlet nozzle 1206 installed on the fourth air chamber 1201. The other end of the push-pull frame 1204 is movably connected to the fourth plunger 1202. The second driving spur gear 1203 meshes with the first driving spur gear 1102. The first driving spur gear 1102 is used to drive the push-pull frame 1204 to swing, and the push-pull frame 1204 is used to drive the fourth plunger 1202 to move in the fourth air chamber 1201; when the channel 1105 flips upward, the gas in the fourth air chamber 1201 flows into the first air outlet nozzle 1205; when the channel 1105 flips downward, the gas in the fourth air chamber 1201 flows into the second air outlet nozzle 1206;As the bench 301 moves along the H1 direction, the first driving spur gear 1102 rotates due to the pulling effect of the movable connection of the rocker arm 1103, driving the jib 1104 and the chute 1105 to turn downward until the chute 1105 turns below the roll body 302. During the turning process, the first driving spur gear 1102 drives the push-pull frame 1204 to swing through the meshing drive with the second driving spur gear 1203, and generates a pulling force on the fourth plunger 1202. Through the second air outlet nozzle 1206, the gas in the fourth air chamber 1201 is discharged and blown to the corresponding rolling groove 305 to cool the inner wall of the rolling groove 305 and the waste residue. The waste residue cleared from the rolling groove 305 falls on the conveyor belt 1106. Part of it rolls down and is discharged along the conveyor belt 1106 downward, and the other part of the waste residue adhering to the conveyor belt 1106 moves close to the scraper 1107 with the conveyor belt 1106. The scraper 1107 scrapes off the waste residue (the cleared waste residue has high heat and is easy to adhere in the chute 1105 and cannot be discharged. A conveyor belt 1106 is arranged in the chute 1105, and it operates by sending a signal when the chute 1105 rotates into place, and cooperates with the scraping plate in the chute 1105 to scrape off the adhered slag and facilitate sliding). When the chute 1105 turns upward and resets, the push-pull frame 1204 generates a thrust on the fourth plunger 1202. Through the first air outlet nozzle 1205, the gas in the fourth air chamber 1201 is discharged and blown to the corresponding conveyor belt 1106 to blow the remaining dust particles on the conveyor belt 1106 (there may be adhered dust on the conveyor belt 1106. When the chute 1105 is directly turned upward, the dust is easy to fall on the transportation track).;

[0025] Please refer to Figures 1 - 5 、 Figures 11 - 16, in this embodiment, an ejection assembly is installed on the roll assembly, and an ejector block 1304 is installed on the ejection assembly. The ejector block 1304 is arranged in the rolling groove 305. The input end of the ejection assembly is connected to the output end of the transmission assembly. The ejection assembly is used to drive the ejector block 1304 to move in the rolling groove 305. The ejection assembly includes a fifth air chamber 1301 arranged in the roll body 302, a fifth plunger 1302 movably connected in the fifth air chamber 1301, and a fifth return spring 1303 with one end connected to the fifth plunger 1302. The ejector block 1304 is fixedly connected to the fifth plunger 1302, and the other end of the fifth return spring 1303 is connected in the fifth air chamber 1301. The fifth return spring 1303 is used to drive the fifth plunger 1302 to move in the fifth air chamber 1301. When the top ring 907 approaches the middle of the rolling groove 305, the ejector block 1304 extends radially out of the rolling groove 305 along the roll body 302. When the top ring 907 moves away from the middle of the rolling groove 305, the ejector block 1304 retracts radially into the rolling groove 305 along the roll body 302. The ejection assembly further includes a sixth air chamber 1305 connected to the fifth air chamber 1301 and a sixth plunger 1306 movably connected in the fifth air chamber 1301. One end of the sixth plunger 1306 is fixedly connected to the adjacent solenoid 903. When the top ring 907 approaches the middle of the rolling groove 305, the gas in the sixth air chamber 1305 flows into the fifth air chamber 1301. When the top ring 907 moves away from the middle of the rolling groove 305, the gas in the fifth air chamber 1301 flows into the sixth air chamber 1305. During the movement of the solenoid 903, the sixth plunger 1306 is driven to move in the sixth air chamber 1305 together (when the top ring 907 extends out of the rolling groove 305, the gas in the sixth air chamber 1305 flows towards the fifth air chamber 1301, and when the top ring 907 retracts into the rolling groove 305, the gas in the fifth air chamber 1301 flows towards the sixth air chamber 1305). When the pressure in the fifth air chamber 1301 increases, the fifth plunger 1302 overcomes the elastic force of the fifth return spring 1303 and drives the ejector block 1304 to extend out of the rolling groove 305 to break the waste residue connected in sheets by the extrusion of the top ring 907 (when pushing the waste residue, if there is too much remaining waste residue, the two side top rings 907 move towards each other and squeeze, sometimes compressing the waste residue into continuous block sheets, which are difficult to fall off by being hoop-shaped on the rolling groove 305. Therefore, by the extended ejector block 1304, the block-shaped residual material is broken, making it easier to fall off).

[0026] Workflow: After the rolling of the metal forging is completed, the user operates the drive machine 201. Through the connection of the lifting platform 202 and the lifting rod 203, the driving bench 301 together with the roll assembly composed of the roll body 302, the roll head 303 and the roll tail 304 is driven to move along the H1 direction. While the driving bench 301 is moving, a squeezing force is applied to the air hood 401 in cooperation with the frame 1, causing the gas in the air hood 401 to flow into the first air chamber 403 through the air delivery pipe 402. The air pressure in the upper space of the first air chamber 403 increases, pushing the first plunger 404 to move downward against the elastic force of the first return spring 405. The gas in the lower space of the first air chamber 403 flows into the second air chamber 601 and the third air chamber 701 respectively through the exhaust pipe 406, the DC pipe 501 and the shunt pipe 502, causing the second plunger 605 to move in the second air chamber 601 against the elastic force of the second return spring 606, making the ejector rod 607 approach the transmission disc 308, and the third plunger 702 to move in the third air chamber 701 against the elastic force of the third return spring 704, making the locking pin 703 move away from the locking disc 603. As the driving bench 301 moves, the rocker arm 1103 exerts a pulling effect on the first transmission spur gear 1102, causing the first transmission spur gear 1102 to drive the lifting arm 1104 and the channel 1105 to turn downward. During the turning process, the first transmission spur gear 1102 drives the push-pull frame 1204 to swing through the meshing transmission with the second transmission spur gear 1203. The push-pull frame 1204 exerts a pulling force on the fourth plunger 1202, controlling the gas in the fourth air chamber 1201 to be discharged from the second air outlet nozzle 1206 and blown to the corresponding rolling groove 305 to cool the inner wall of the rolling groove 305 and the waste residue; When the roll assembly moves to the preset value M1, the docking head 608 on the ejector rod 607 completely enters the docking groove 309 on the drive disk 308 (the docking head 608 and the docking groove 309 can adopt a cross-shaped structure or other keyway structures that can form a limit), and the locking pin 703 also completely disengages from the locking hole 604 on the locking disk 603. In addition, the channel 1105 also completely flips to the lower side of the roll assembly. At this time, the tension sensor 205 also detects that the pulling force value of the tension spring 204 reaches F1 and sends a signal to the motor 306. The motor 306 starts and controls the rotation of the roll assembly through the meshing transmission between the driving gear 307, the driven gear 310, and the gear ring 311. At the same time, the motor 306 also transmits power to the ejector rod 607 and the second air chamber 601 through the docking between the drive disk 308 and the ejector rod 607 (the docking head 608 and the docking groove 309 form a limit). Through the meshing transmission between the bevel gear seat 602 on the second air chamber 601 and the first transmission bevel gear 801, and in cooperation with the transmission between the transmission gear 803 and the tooth chain 804, the second transmission bevel gear 802 rotates continuously. The second transmission bevel gear 802 then transmits power to the third transmission bevel gear 902 and the screw sleeve 901 that mesh with it. Under the screw thread transmission action between the screw tube 903 and the screw sleeve 901, the screw tube 903 moves along the central axis direction of the roll assembly, prompting the slip ring 904 and the support tube 905 to push the top ring 907 out from the side wall of the rolling groove 305 (in this solution, there are two top rings 907 in each rolling groove 305, and the two top rings 907 move towards each other to squeeze and gather the remaining waste residue to the middle of the rolling groove 305. It should be noted that when the two top rings 907 move towards each other to the threshold value, there is still a certain distance between them). At the same time, the movement of the screw tube 903 also synchronously drives the sixth plunger 1306 to move in the sixth air chamber 1305, pushing the gas in the sixth air chamber 1305 into the fifth air chamber 1301, increasing the air pressure in the fifth air chamber 1301, so that the fifth plunger 1302 overcomes the elastic force of the fifth return spring 1303 and moves along the fifth air chamber 1301, pushing the top block 1304 out from the inner wall of the rolling groove 305 (between two adjacent top rings 907). Cooperating with the top rings 907 that move towards each other, the waste residue remaining in the rolling groove 305 is cleared (realizing the function of the roll assembly rotating while cleaning, and can assist in throwing out the cleaned waste residue. It should be noted that when the two top rings 907 in the same rolling groove 305 move towards each other to the threshold value and are close to the middle of the rolling groove 305, the motor 306 outputs reverse power to control the two top rings 907 to move back and reset. In practical applications, a sensor can be set on the screw tube 903 to detect the displacement amount); The waste residue drops onto the conveyor belt 1106 in the chute 1105. The larger waste residues directly slide downward along the surface of the conveyor belt 1106 (a chain plate conveyor belt 1106 can be used, which is not easily burned by the high-temperature waste residues) and are discharged into the collection area on the side of the transportation track. Some of the waste residues adhered to the conveyor belt 1106 move obliquely upward with the conveyor belt 1106. After contacting the scraper 1107, they are scraped off and further slide down; After the roll assembly is cleaned, the drive motor 201 drives the gantry 301 together with the roll assembly to move along the H2 direction. The tension sensor 205 detects a signal change and sends a signal to the motor 306 to stop running. At the same time, the gas in the first air chamber 403 flows into the air hood 401, and the gas in the second air chamber 601 and the third air chamber 701 flows into the first air chamber 403. The second plunger 605 moves in the second air chamber 601 under the elastic force of the second return spring 606, causing the ejector rod 607 to move away from the drive disk 308. And the third plunger 702, under the elastic force of the third return spring 704, causes the locking pin 703 to approach the locking disk 603. As the gantry 301 moves, the rocker arm 1103 exerts a pushing force on the first transmission spur gear 1102, causing the first transmission spur gear 1102 to drive the boom 1104 and the chute 1105 to flip upward. During the flipping process, the first transmission spur gear 1102, through the meshing drive with the second transmission spur gear 1203, drives the push-pull frame 1204 to swing. The push-pull frame 1204 exerts a thrust on the fourth plunger 1202, controlling the gas in the fourth air chamber 1201 to be discharged from the first air nozzle 1205 and blown to the corresponding conveyor belt 1106 to blow the dust particles remaining on the conveyor belt 1106; When the roll assembly moves to the preset value M2, the docking head 608 on the ejector rod 607 disengages from the docking groove 309 on the drive disk 308, and the locking pin 703 also enters the locking hole 604 on the locking disk 603. In addition, the chute 1105 also flips to one side of the roll assembly. At this time, the tension sensor 205 also detects that the pulling force value of the tension spring 204 reaches F2 and sends a signal to the motor 306 to start again, controlling the roll assembly to rotate and perform rolling treatment on the metal forging on the transportation track.
