Description

Technical Field

[0001] This utility model relates to the technical field of flange processing equipment, specifically to a flange forming equipment that integrates feeding, shaping, stamping and cooling conveying functions. Background Technology

[0002] Flanges are commonly used fittings in pipe connections and are widely used in industries such as chemical, petroleum, and power. Flanges are typically made by casting molten iron into a mold, cooling it to form a flange blank, and then processing it through shaping, stamping, and other processes.

[0003] Currently, the production and processing of flanges are mostly completed by independent equipment, requiring manual or simple mechanical transfer and connection between processes. The loading process typically involves manually removing the high-temperature flange blanks from the mold and placing them onto the forming equipment, which is labor-intensive, involves high-temperature operating environments, and poses safety hazards. In the forming process, both the inner and outer rings of the flange blank need to be shaped simultaneously. Existing forming equipment lacks reliable end support for the forming shaft during rotation, affecting forming accuracy. After the stamping process, the flange blank remains at a high temperature, requiring natural cooling or separate cooling treatment, which is time-consuming and impacts production efficiency.

[0004] Therefore, there is an urgent need for a flange forming equipment with high integration, tight connection between each process, and the ability to automate the entire process of flange blank processing from shaping to stamping to cooling. Utility Model Content

[0005] The purpose of this invention is to provide a flange forming equipment to solve the problems of dispersed processing steps, low material transfer efficiency, insufficient forming accuracy, and long cooling time in the existing flange blank processing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A flange forming apparatus, comprising: The loading mechanism includes a loading platform and a loading robot mounted on the loading platform, used to clamp and transfer the flange blank to the shaping mechanism. The forming mechanism includes a forming groove and a forming frame disposed in the forming groove. The forming frame is provided with a forming shaft and a forming disc located above the forming shaft. The forming shaft and the forming disc cooperate to form the inner and outer rings of the flange blank. The stamping mechanism includes a stamping frame and a stamping table located below the stamping frame. The stamping frame is equipped with a liftable punch for stamping and forming the shaped flange blank. The cooling conveying mechanism includes a cooling tank and a conveyor belt disposed in the cooling tank, which is used to cool the stamped flange blank and convey it to the next process. The transfer robot is used to clamp and transfer the shaped flange blank to the stamping table, and then clamp and transfer the stamped flange blank to the cooling conveyor mechanism.

[0007] By adopting the above technical solution, the feeding mechanism, forming mechanism, stamping mechanism, and cooling conveying mechanism are integrated into a single production line. An intermediate robotic arm is used to automatically transfer materials between forming and stamping, and between stamping and cooling, achieving fully automated processing of flange blanks from feeding to cooling. The feeding robotic arm picks up the flange blank from the mold and transfers it to the forming mechanism. The forming shaft and forming disc in the forming mechanism simultaneously form the inner and outer rings of the flange blank. The stamping mechanism stamps the formed flange blank, and the cooling conveying mechanism simultaneously conveys and cools the stamped flange blank. The intermediate robotic arm seamlessly connects the various processes, resulting in high production efficiency, minimal human intervention, and good operational safety.

[0008] Preferably, the loading robot includes a rotating base, a first arm swayably mounted on the rotating base, and a second arm swayably mounted on the first arm. The end of the second arm is provided with a clamping assembly. The clamping assembly includes an opening and closing assembly driven by a linear drive and two clamping arms driven to open and close by the opening and closing assembly. The end of the clamping arm is provided with a clamping block for clamping the outer ring of the flange blank.

[0009] By adopting the above technical solution, the loading robot employs a multi-arm swing structure consisting of a rotating base, a first arm, a second arm, and a clamping assembly. The rotating base provides horizontal rotational motion, the first arm provides vertical swinging motion, and the second arm provides further vertical swinging motion, enabling the clamping assembly to flexibly reach different positions. The clamping assembly drives the opening and closing assembly via a linear drive, which in turn drives the two clamping arms to open and close. The clamping blocks at the ends of the clamping arms grip the outer ring of the flange blank. The loading robot can stably grip flange blanks in high-temperature environments, replacing manual operation, reducing labor intensity, and eliminating safety hazards.

[0010] Preferably, the transfer robot includes a rotating base, a first arm swayably mounted on the rotating base, and a second arm swayably mounted on the first arm. The end of the second arm is provided with a clamping assembly. The clamping assembly includes an opening and closing assembly driven by a linear drive and two clamping arms driven to open and close by the opening and closing assembly. The end of the clamping arm is provided with a clamping member, which has an inner ring clamping part and an outer ring clamping part, so as to realize the inner ring clamping or outer ring clamping of the flange blank.

[0011] By adopting the above technical solution, the transfer robot is structurally basically the same as the loading robot. The difference lies in the fact that the clamping component at the end of its clamping arm has an inner ring clamping part and an outer ring clamping part, which can clamp both the inner and outer rings of the flange blank. One robot can accommodate two clamping methods, adapting to the changing clamping requirements of the flange blank between different processes, with strong clamping adaptability and reduced equipment investment.

[0012] Preferably, the shaping mechanism further includes a swing frame, the lower end of which is hinged to a hinge point on the shaping groove, and the upper end of the swing frame is provided with a rotating support. When the swing frame swings to the vertical working position, the end of the front end of the shaping shaft is accommodated in the rotating support. A support frame is fixedly connected to the side of the swing frame near the shaping shaft, and a support groove is provided on the support frame, and the rear end of the shaping shaft is accommodated in the support groove.

[0013] By adopting the above technical solution, the shaping mechanism is equipped with a swing frame, the lower end of which is hinged to the shaping groove, allowing it to swing around the hinge point in a vertical plane. A rotating support is provided at the upper end of the swing frame. When the swing frame swings to the vertical working position, the front end of the shaping shaft is precisely housed in the rotating support, providing radial rotation positioning and support for the front end of the shaping shaft, preventing radial runout during rotation, and improving shaping accuracy. A support frame is fixedly connected to the side of the swing frame near the shaping shaft, and the support frame has a support groove. The rear end of the shaping shaft is housed in the support groove, providing support for the rear end of the shaping shaft. With simultaneous support at both ends, the shaping shaft experiences balanced force during rotation, resulting in good rigidity and stable shaping quality.

[0014] Preferably, the front end of the shaping shaft is tapered and the rear end is straight; the shaping frame is provided with a push drive component, which is connected to a push ring, which is sleeved on the shaping shaft; a cooling nozzle is provided on the side of the shaping shaft on the shaping frame.

[0015] By adopting the above technical solution, the front end of the forming shaft is tapered, and the rear end is a straight shaft. When the loading robot grips the flange blank, the flange blank first passes through the tapered front end, which serves as a guide and positioner, facilitating the smooth insertion and positioning of the flange blank onto the straight shaft rear end, thus improving loading efficiency and positioning accuracy. The flange blank is shaped on the rear end of the forming shaft. After shaping, the push drive on the forming frame drives the push ring to move along the forming shaft, pushing the flange blank from the rear end to the front end, facilitating the transfer robot to perform the next gripping and removal. The push drive enables automatic unloading without manual intervention, improving the degree of automation. Cooling nozzles on the side of the forming shaft water-cool the flange blank during the shaping process, reducing the shaping temperature, preventing overheating and deformation of the blank, and extending the service life of the forming shaft and forming disc.

[0016] Preferably, the shaping mechanism further includes a rotary drive component for driving the shaping disk to rotate, and the outer ring of the shaping disk is provided with an annular groove.

[0017] By adopting the above technical solution, the rotary drive component can use a geared motor to drive the forming disc to rotate. The outer ring of the forming disc is provided with an annular groove, which mates with the outer ring edge of the flange blank. When the forming disc rotates, it shapes the outer ring of the flange blank, giving the outer ring of the flange blank a precise contour shape.

[0018] Preferably, the shaping frame includes a lower frame and an upper frame. The shaping shaft is rotatably mounted on the lower frame. The upper frame is provided with a lifting seat that can be raised and lowered. The shaping disc is mounted on the lifting seat. The lifting seat is driven by a lifting drive component to move the screw structure up and down. A lifting guide structure is provided between the lifting seat and the side wall of the mounting groove.

[0019] By adopting the above technical solution, the forming frame is divided into a lower frame and an upper frame. The forming shaft is rotatably mounted on the lower frame, while the forming disc is mounted on a lifting seat on the upper frame. The functional areas are clearly defined, facilitating installation and maintenance. The lifting seat moves up and down within the mounting slot via a lifting drive mechanism that powers a lead screw. The lead screw transmission has high precision, ensuring smooth and controllable lifting motion. It can precisely adjust the distance between the forming disc and the forming shaft to accommodate flange blanks of different thicknesses. A lifting guide structure is provided between the side walls of the lifting seat and the mounting slot to guide the lifting motion of the lifting seat, ensuring uniform clearance between the forming disc and the forming shaft and high forming accuracy.

[0020] Preferably, a grinding assembly is provided above the two side walls of the shaping groove. The grinding assembly includes a fixed seat fixed to the side wall of the shaping groove, a translation drive component provided on the fixed seat, a grinding bracket connected to the translation drive component, and a grinding wheel rotatably provided on the grinding bracket. The two grinding wheels are driven to translate by their respective translation drives.

[0021] By adopting the above technical solution, the grinding components installed above the side walls of the forming groove can grind and shape the two edges of the flange blank. The two grinding wheels are independently driven by their respective translational drive components, allowing for adjustment of the distance between the grinding wheels and the edges of the flange blank to accommodate the grinding needs of flange blanks of different sizes. The grinding wheels perform grinding while the flange blank is being shaped on the forming shaft; the forming and grinding processes are carried out simultaneously, saving the time of separate grinding and improving production efficiency.

[0022] Preferably, the stamping table is provided with a groove that matches the shape of the finished flange blank, and the bottom of the groove is provided with a liftable ejector block; the cooling tank is provided with cooling water, and the conveyor belt extends obliquely from the bottom of the cooling tank to the top of the cooling tank, and a conveyor drive unit for driving the conveyor belt is provided above the cooling tank.

[0023] By adopting the above technical solution, the stamping table is equipped with a groove that matches the shape of the finished flange blank. The flange blank is placed in the groove, and the punch presses down to stamp and form it. The groove ensures the stability of the flange blank's position during the stamping process, resulting in high stamping accuracy. A liftable ejector block is installed at the bottom of the groove. After stamping, the ejector block rises to push the flange blank out of the groove, facilitating transfer by a robotic arm and avoiding damage to the flange blank surface caused by manual prying. The conveyor belt of the cooling conveyor mechanism extends obliquely from the bottom of the cooling tank upwards. After the flange blank is placed on the conveyor belt, it is in full contact with the cooling water during conveying, achieving simultaneous conveying and cooling, saving separate cooling time and improving production efficiency. The conveyor drive unit is located above the cooling tank, higher than the cooling water level, preventing water immersion damage to the drive unit and ensuring the reliable operation of the conveyor mechanism.

[0024] Preferably, the flange blank includes a main body and an outer edge, with the main body inclined toward the outer edge. When the flange blank is located on the rear end of the forming shaft, the outer edge is close to the front end of the forming shaft while the main body is far away from the front end of the forming shaft.

[0025] By adopting the above technical solution, when the flange blank is located on the rear end of the forming shaft, its outer edge is close to the front end of the forming shaft while its main body is far from the front end. This placement direction ensures that the outer edge of the flange blank faces the front end of the forming shaft, facilitating the forming of the outer edge. Simultaneously, the main body is located on the straight shaft-like portion at the rear end of the forming shaft, providing stable support. The inclination of the main body of the flange blank towards its outer edge ensures accurate alignment of the annular groove of the forming disc with the outer edge of the flange blank, resulting in a good forming effect.

[0026] Compared with the prior art, the present invention has, but is not limited to, the following main beneficial effects: 1. By integrating the feeding mechanism, forming mechanism, stamping mechanism and cooling conveying mechanism into a single production line, and setting up a transfer robot to realize the automatic transfer of materials between forming and stamping, and between stamping and cooling, the entire process of flange blank processing from feeding to cooling conveying is automated, resulting in high production efficiency and close connection between each process.

[0027] 2. The loading robot and the transfer robot are specially designed for clamping the outer ring and the inner / outer ring of the flange blank, respectively. The transfer robot has both inner ring clamping and outer ring clamping functions, adapting to the changing clamping requirements of the flange blank between different processes, and has strong clamping adaptability.

[0028] 3. The shaping mechanism uses a swing frame to provide rotational support for the front and rear ends of the shaping shaft, which improves the stability and shaping accuracy of the shaping shaft during rotation. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0032] The following is combined with Figures 1 to 13 The technical solution of this utility model will be described in further detail below.

[0033] This embodiment provides a flange forming equipment that integrates feeding, shaping, stamping and cooling conveying functions, realizing fully automated processing of flange blanks 600 from feeding to cooling conveying.

[0034] Please refer to the flange forming equipment of this embodiment, which mainly includes a feeding mechanism 100, a forming mechanism 200, a stamping mechanism 300, a cooling conveying mechanism 400, and a transfer robot 500.

[0035] Feeding mechanism 100 The loading mechanism 100 includes a loading platform 101 and a loading robot 102 mounted on the loading platform 101. The loading robot 102 is used to pick up the flange blank 600 from the mold and transfer it to the forming mechanism 200. The flange blank 600 is a high-temperature iron ring formed after molten iron is poured into a mold and cooled. It includes a main body 601 and an outer edge 602, with the main body 601 inclined towards the outer edge 602.

[0036] The loading robot 102 includes a rotating base 501, which is rotatably mounted on the loading platform 101 and rotates horizontally via a rotary drive. A first arm 502 is mounted on the rotating base 501 and is vertically swingable, driven by a first motor. A second arm 503 is mounted on the first arm 502 and is vertically swingable, driven by a second motor. The first arm 502 and the second arm 503 work together to achieve flexible adjustment of their spatial position.

[0037] The second arm 503, located away from the first arm 502, is equipped with a clamping assembly. The clamping assembly includes an opening / closing assembly 505 driven by a linear drive 504, and two clamping arms 506 driven to open and close by the opening / closing assembly 505. The linear drive 504 can be a cylinder, and the opening / closing assembly 505 can be a connecting rod assembly hinged between the cylinder piston rod and the clamping arms 506, as long as it enables the relative opening and closing of the two clamping arms 506. The ends of the clamping arms 506 are equipped with clamping blocks 103. The linear drive 504 drives the opening / closing assembly 505 to open or close the two clamping arms 506 relative to each other, and the clamping blocks 103 clamp the outer ring of the flange blank 600.

[0038] Plastic Surgery Unit 200 The shaping mechanism 200 includes a shaping groove 201 located on one side of the loading platform 101. The shaping groove 201 is elongated. A shaping frame 202 is fixedly installed inside the shaping groove 201. The shaping frame 202 is upright and includes a lower frame part 219 and an upper frame part 220.

[0039] A shaping shaft 203 is provided on the lower frame 219 along the length of the shaping groove 201. The shaping shaft 203 is driven to rotate by a drive source (such as a drive motor). The front end 209 of the shaping shaft 203 is tapered, and the rear end 210 is a straight shaft. The loading robot 102 grips the flange blank 600 and first passes it through the tapered part of the front end 209. Using the guiding effect of the tapered structure, the flange blank 600 is positioned on the straight shaft part of the rear end 210. When the flange blank 600 is located on the rear end 210, the outer edge 602 is close to the front end 209, while the main body 601 is away from the front end 209.

[0040] The upper frame 220 has a mounting groove, within which a lifting seat 221 is movably mounted. The lifting seat 221 moves up and down within the mounting groove via a lifting drive mechanism that drives a lead screw. A lifting guide structure 222 is provided between the lifting seat 221 and the side wall of the mounting groove to guide the lifting movement of the lifting seat 221. A shaping disc 204 is mounted on the lifting seat 221, corresponding to the shaper shaft 203, and is connected to the lifting seat 221 via a connecting shaft. The outer ring of the shaping disc 204 has an annular groove 218 for shaping the outer edge of the flange blank 600. During shaping, the lifting seat 221 moves downward, causing the shaping disc 204 to abut against the outer ring of the flange blank 600. The shaper shaft 203 rotates to shape the inner ring of the flange blank 600, while the shaping disc 204 rotates to shape the outer ring of the flange blank 600.

[0041] The shaping slot 201 is provided with a rotary drive component on the other side of the shaping frame 202 relative to the shaping shaft 203, which drives the shaping disk 204 to rotate. The rotary drive component can be a geared motor.

[0042] A connecting rod is connected between the two side walls of the forming groove 201, and a swing frame 205 is oscillatingly connected to the connecting rod. The swing frame 205 is driven to rotate around the connecting rod by a swing drive (such as a cylinder) located at the bottom of the forming groove 201. The upper end of the swing frame 205 has an opening, and a rotating support 206 (such as a bearing) is provided in the opening. A support frame 207 is fixedly connected to the side of the swing frame 205 near the forming shaft 203, and a support groove 208 is provided on the support frame 207. When the swing frame 205 swings to the vertical working position perpendicular to the connecting rod, the end of the front end 209 of the forming shaft 203 is precisely accommodated in the rotating support 206, and the rear end 210 of the forming shaft 203 is accommodated in the support groove 208, providing rotational positioning and support at both ends for the rotation of the forming shaft 203, thereby improving the forming accuracy. When it is necessary to remove the flange blank 600 from the forming shaft 203, the swing frame 205 swings away from the forming shaft 203. Since the front end 209 of the shaping shaft 203 is a tapered structure, when the swing frame 205 swings to the side away from the shaping shaft 203, the support frame 207 will not collide or interfere with the shaping shaft 203.

[0043] The lower frame 219 is equipped with a push drive component 211 (such as a drive cylinder), which is connected to a push ring 212. The push ring 212 is sleeved on the shaping shaft 203 and located at the rear end 210. After shaping, the push drive component 211 drives the push ring 212 to move along the shaping shaft 203, pushing the flange blank 600 from the rear end 210 of the shaping shaft 203 to the front end 209, so that the transfer robot 500 can grasp and move it.

[0044] The forming frame 202 is also equipped with a cooling nozzle 213 on the side of the forming shaft 203, which is used to water cool the flange blank 600 during forming, reduce the forming temperature, and prevent the blank from overheating and deforming.

[0045] A grinding assembly is also provided above the two side walls of the forming groove 201. The grinding assembly includes a fixed seat 223 fixed to the side wall of the forming groove 201, a translation drive 224 (such as a cylinder) provided on the fixed seat 223, a grinding bracket 225 connected to the translation drive 224, and grinding wheels 226 rotatably provided on the grinding bracket 225. The two grinding wheels 226 are driven to translate by their respective translation drives 224, and grind and shape the two side edges of the flange blank 600 when it is being shaped on the forming shaft 203. The two grinding wheels 226 are driven independently and their distance from the edge of the flange blank 600 can be adjusted to meet the grinding requirements of flange blanks 600 of different sizes.

[0046] 300 stamping mechanism The stamping mechanism 300 includes a stamping frame 301 located on one side of the loading platform 101 and a stamping table 302 located below the stamping frame 301. The stamping table 302 has a groove 304 adapted to the finished shape of the flange blank 600 for placing the shaped flange blank 600. A liftable ejector block 305 is located at the bottom of the groove 304 on the stamping table 302, and the ejector block 305 is driven to rise and fall by a cylinder located inside the stamping table 302. A liftable punch 303 is located on the stamping frame 301 above the stamping table 302. The punch 303 presses down to stamp the flange blank 600 located in the groove 304 of the stamping table 302. After stamping, the ejector block 305 rises to push the flange blank 600 out of the groove 304, facilitating the transfer robot 500 to pick it up.

[0047] Cooling conveyor 400 The cooling conveying mechanism 400 includes a cooling tank 401 located on one side of the stamping frame 301 and the forming tank 201, arranged side-by-side. The cooling tank 401 contains cooling water for water cooling of the stamped flange blank 600. A conveyor belt 402 is installed inside the cooling tank 401, extending obliquely upwards from the bottom of the cooling tank 401. The conveyor belt 402 transports the flange blank 600 from the cooling water to the position above the cooling tank 401 for the next process. A mounting frame is located above the cooling tank 401, and a conveying drive component 403 (such as a drive motor) is mounted on the mounting frame. The conveying drive component 403 is higher than the water level in the cooling tank 401, and drives a drive roller to rotate via a transmission component (such as a belt), thereby driving the conveyor belt 402. The placement of the conveying drive component 403 above the water level prevents water immersion damage and ensures reliable operation of the conveying mechanism.

[0048] 500 transfer robotic arms The transfer robot 500 is located on the loading platform 101, on one side of the loading robot 102. It is used to clamp and transfer the shaped flange blank 600 to the stamping table 302, and to clamp and transfer the stamped flange blank 600 to the cooling conveying mechanism 400.

[0049] The basic structure of the transfer robot 500 is the same as that of the loading robot 102, including a rotating base 501, a first arm 502 that is swayably mounted on the rotating base 501, and a second arm 503 that is swayably mounted on the first arm 502. The difference lies in the clamping assembly at the end of the second arm 503.

[0050] The gripping assembly of the transfer robot 500 includes an opening and closing assembly 505 driven by a linear drive 504 and two gripping arms 506 driven to open and close by the opening and closing assembly 505. The opening and closing assembly 505 of the transfer robot 500 has the same structure as the opening and closing assembly 505 of the loading robot 102.

[0051] The end of the gripping arm 506 of the transfer robot 500 is vertically downward to form a connecting frame 510, which is L-shaped. A connecting arm 511 is fixedly connected to the connecting frame 510. The connecting arm 511 includes a fixing section 512 fixedly connected to the bottom end of the connecting frame 510, a main body section 513 located in the middle of the connecting arm 511, and a mounting section 514 located at the bottom of the connecting arm 511. The width of the mounting section 514 is smaller than the width of the main body section 513, and the bottom of the mounting section 514 has abutment sections 515 extending to both sides in the width direction of the mounting section 514. A clamping member 507 is fixedly connected to the mounting section 514 near the main body section 513. The clamping member 507 includes an inner ring clamping portion 508 located on the outer side of the mounting section 514 (i.e., the side away from the other gripping arm 506), and an outer ring clamping portion 509 located on the inner side of the mounting section 514. The inner ring clamping part 508 is provided with a hollow groove 516, and the clamping part 507 is fixed on the mounting section 514 through the cooperation of the hollow groove 516 and the mounting section 514.

[0052] The transfer robot 500 can clamp both the inner and outer rings of the flange blank 600. When clamping the inner ring, the mounting section 514 and the abutment section 515 open and abut against the inner ring of the flange blank 600 to achieve clamping. The inner ring clamping part 508 mainly serves a clamping and positioning function. When clamping the outer ring, the mounting section 514 and the abutment section 515 press against the outer ring of the flange blank 600 to achieve clamping. The outer ring clamping part 509 mainly serves a clamping and positioning function.

[0053] The outer clamping portions 509 on the two clamping arms 506 are inclined upwards, and the two outer clamping portions 509 are inclined at different angles. This ensures that when the two clamping arms 506 approach and close, the two outer clamping portions 509 close in an interlaced manner, preventing collisions and interference that could cause them to fail to close or have a small closing distance. The two inner clamping portions 508 are also inclined upwards.

[0054] Work process When the flange forming equipment is working, the loading robot 102 rotates above the mold, the first arm 502 and the second arm 503 swing to adjust their positions, the clamping assembly opens, the clamping arm 506 closes, and the clamping block 103 clamps the outer ring of the flange blank 600. The loading robot 102 transfers the flange blank 600 to the forming mechanism 200, so that the flange blank 600 passes through the tapered front end 209 of the forming shaft 203 and is positioned on the straight shaft-like part of the rear end 210.

[0055] The swing frame 205 swings to the vertical working position, and the rotating support 206 and the support groove 208 respectively support the front end 209 and rear end 210 of the shaping shaft 203. The lifting seat 221 moves down, and the shaping disc 204 abuts against the outer ring of the flange blank 600. The shaping shaft 203 rotates to shape the inner ring of the flange blank 600, and the rotation drive drives the shaping disc 204 to rotate to shape the outer ring of the flange blank 600. The grinding assembly simultaneously grinds the two side edges of the flange blank 600. The cooling nozzle 213 water-cools the shaping area.

[0056] After shaping, the swing frame 205 swings away from the shaping shaft 203, and the push ring 212 pushes the flange blank 600 to the front end 209 of the shaping shaft 203. The transfer robot 500 uses an inner ring clamping method to pick up the flange blank 600 and transfer it to the groove 304 of the stamping table 302.

[0057] The punch 303 presses down to perform stamping. After stamping, the ejector block 305 rises to eject the flange blank 600. The transfer robot 500 uses an outer ring clamping method to pick up the flange blank 600 and transfer it to the conveyor belt 402 of the cooling tank 401. The flange blank 600 is conveyed and cooled on the conveyor belt 402, and then conveyed to a position above the cooling tank 401 to enter the next process.
