Description

Technical Field

[0001] The invention belongs to the technical field of tank body processing, and in particular relates to a large tank body rounding device. Background Art

[0002] Large tanks usually refer to large containers used to store various liquids or gases, with a capacity ranging from a few liters to tens of thousands of liters. They are usually made of metal (such as steel, aluminum alloy) or plastic (such as polyethylene, polypropylene) and have sealing properties to prevent leakage. Large tanks are widely used. For example, they are often used to store raw materials, finished products or waste in industrial fields such as chemicals, petroleum, food, and pharmaceuticals. In addition, in agriculture and family life, large tanks can also be used to store water, gas, etc. For those industries that need to store various liquids or gases during transportation, large tanks are also indispensable equipment.

[0003] The main body of a large tank is generally formed by a steel plate using a rolling machine, and then the two ends are welded and fixed. However, although the rolling machine can roll the steel plate into a cylindrical tank structure, after welding, the structure of the tank is not a very regular perfect circle, and there is still a certain degree of deformation, mostly in an elliptical structure. For some large tank equipment with high precision requirements, after the large tank is welded, it is necessary to perform full circle processing to make it infinitely close to a perfect circle structure, so that the tank can be subsequently spliced ​​and welded with the tank bottom and tank cover. At present, the most commonly used full circle processing equipment is to use a rolling machine. After the tank is welded, After that, the can body is rolled again using a rolling machine to make it closer to a perfect circular structure. However, although the second rolling using a rolling machine can achieve a certain rounding effect, the rounding of the rolling machine is achieved by continuously bending and shaping the sides of the can body with three sets of staggered rollers, and it is impossible to shape the sides of the can body at the same time. Therefore, after the second shaping using the rolling machine, although the can body is rounder than before welding, the corrected part will still have a certain deformation, which makes it impossible to achieve the best rounding effect. When welding the can cover and the bottom of the can later, it is still necessary to manually use internal support equipment to perform slight correction on the can body, which also affects the production and processing progress to a certain extent. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a large tank body rounding equipment.

[0005] The technical solution adopted to solve the above technical problems is: a large tank body rounding equipment, including a processing platform, a tank body rounding positioning mechanism for processing the tank body to be processed is installed on one side of the top of the processing platform, and the tank body rounding positioning mechanism includes a support seat, and the support seat is rotatably connected with a first positioning mold and a second positioning mold respectively. The first positioning mold and the second positioning mold can be opened and closed under the drive of a hydraulic opening and closing mechanism. When processing the tank body, the tank body to be processed can be hoisted between the first positioning mold and the second positioning mold, and then the first positioning mold and the second positioning mold are closed to achieve positioning and limiting of the tank body to be processed. The inner diameter of the first positioning mold and the second positioning mold after closing is the same as the outer diameter of the tank body to be processed, so that the extrusion correction of the tank body to be processed can also be achieved from the outside;

[0006] The processing platform is also provided with a hydraulic opening and closing mechanism for opening and closing the first positioning mold and the second positioning mold at the same side position;

[0007] A support guide mechanism is fixedly connected to the other side of the top of the processing platform, and a servo pushing mechanism is also provided at the center of the top of the processing platform;

[0008] A rotary drive mechanism is slidably connected to the support and guide mechanism, and a rotary full-circle mechanism is installed at one end of the rotary drive mechanism close to the tank body full-circle positioning mechanism. The rotary full-circle mechanism includes a rotary connection part, a rolling full-circle part and a conical perforation part. The rolling full-circle part and the conical perforation part penetrate the tank body to be processed in the processing state, and rotate and roll the inner hole of the tank body to be processed under the drive of the rotary drive mechanism.

[0009] Furthermore, a horizontally arranged rotating support shaft is installed on the support seat, the first positioning mold and the second positioning mold are both rotatably connected to the rotating support shaft, the first positioning mold and the second positioning mold are respectively provided with a first limiting protrusion and a second limiting protrusion on both sides of the inner wall, and the first positioning mold and the second positioning mold are fixedly connected to a rotating support at the outer center position.

[0010] Through the above technical scheme, the support seat and the rotating support shaft can play a role of rotational support for the first positioning mold and the second positioning mold, so that the first positioning mold and the second positioning mold can be rotated and opened and closed under the control of the hydraulic opening and closing mechanism. When it is necessary to perform full-circle processing on the tank body to be processed, the tank body to be processed can be hoisted between the first positioning mold and the second positioning mold by hoisting equipment, and then the first positioning mold and the second positioning mold are driven by the hydraulic opening and closing mechanism to close the mold, thereby fixing the tank body to be processed between the first positioning mold and the second positioning mold. After the full-circle processing is completed, the hydraulic opening and closing mechanism can drive the first positioning mold and the second positioning mold to open the mold.

[0011] Furthermore, the first positioning mold and the second positioning mold are both provided with a plurality of groups of evenly distributed transverse reinforcing ribs and longitudinal reinforcing ribs, and the thickness of the first limiting protrusion and the second limiting protrusion is less than the thickness of the can body to be processed.

[0012] Through the above technical scheme, multiple groups of evenly distributed transverse reinforcing ribs and longitudinal reinforcing ribs can further enhance the overall strength of the first positioning mold and the second positioning mold. In addition, since the thickness of the first limiting protrusion and the second limiting protrusion is smaller than the thickness of the can body to be processed, when the first positioning mold and the second positioning mold are closed, the first limiting protrusion and the second limiting protrusion can both play a limiting role at the two ends of the can body to be processed, preventing the rotating full circle mechanism from penetrating into or moving out of the inner hole of the can body to be processed and squeezing it out of the can body full circle positioning mechanism. At the same time, the first limiting protrusion and the second limiting protrusion will not affect the rotating full circle mechanism from penetrating and squeezing the inner wall of the can body to be processed.

[0013] Furthermore, the hydraulic opening and closing mechanism includes two positioning grooves opened at the front and rear ends of one side of the top of the processing platform, the bottom of the two positioning grooves are rotatably connected to the opening and closing hydraulic cylinders, the top ends of the two opening and closing hydraulic cylinder piston rods are fixedly connected to the rotating sleeves, and the two rotating sleeves are respectively rotatably connected to the corresponding rotating supports.

[0014] Through the above technical solution, the two opening and closing hydraulic cylinders can drive the first positioning mold and the second positioning mold to open and close the mold through the extension and retraction of the piston rod.

[0015] Furthermore, the support guide mechanism includes two guide brackets fixed to the top of the processing platform, and the two guide brackets are fixedly connected to guide rods, and a connecting rod is also fixedly connected to the side between the two guide brackets away from the tank body full circle positioning mechanism.

[0016] Through the above technical scheme, the two guide brackets can play a supporting role, and the guide rods on the two guide brackets can guide and limit the lateral movement of the rotary drive mechanism to ensure that during the processing, the rotating full circle mechanism at one end of the rotary drive mechanism can accurately penetrate the tank body to be processed. In addition, the connecting rod fixedly connected between the two guide brackets can further enhance the connection strength between the two guide brackets and the stability of the support.

[0017] Furthermore, the servo pushing mechanism includes a first bearing seat and a second bearing seat fixed on the top of the processing platform, a ball screw is rotatably connected between the first bearing seat and the second bearing seat, and an installation groove is opened on the side of the top of the processing platform away from the full-circle positioning mechanism of the tank body, a first servo motor is installed in the installation groove, and the output shaft of the first servo motor is fixedly connected to one end of the ball screw.

[0018] Through the above technical scheme, the servo pushing mechanism is used to drive the rotary drive mechanism to reciprocate in the horizontal direction. When the first servo motor is working, it can drive the ball screw to rotate synchronously through its output shaft, so that the entire rotary drive mechanism and the rotating full circle mechanism can be driven to move horizontally through the ball nut seat, including driving the rotating full circle mechanism through the rotary drive mechanism to insert it into the tank body to be processed for full circle processing, and after the processing is completed, the rotary drive mechanism drives it to move out of the tank body to be processed.

[0019] Furthermore, the rotation drive mechanism includes a movable base, and the front and rear ends of the outer wall of the movable base are respectively fixedly connected to two first guide seats and two second guide seats, and the centers of the first guide seats and the second guide seats are provided with guide holes, and a ball nut seat is also fixedly installed on the bottom of the movable base, and an end cover plate is installed on the end of the movable base away from the full-circle positioning mechanism of the tank body, and a cavity is provided in the movable base, and a mounting plate is also fixedly connected in the cavity, two support bearings are installed on one side of the cavity, and a second servo motor is installed on one side of the mounting plate, and the output end of the second servo motor passes through the mounting plate and is fixedly connected to the mounting disk.

[0020] Through the above technical solution, the mobile base can move horizontally under the drive of the servo pushing mechanism. When the mobile base drives the rotating full-circle mechanism to insert into the inner hole of the tank body to be processed, the output shaft of the second servo motor will start to rotate, and then the entire rotating full-circle mechanism can be driven to rotate in the tank body to be processed through the mounting plate, thereby realizing the full-circle correction of the inner hole of the tank body to be processed.

[0021] Furthermore, the two first guide seats and the two second guide seats are respectively slidably connected to the outer walls of the corresponding connecting rods, and the ball nut seat is sleeved on the outer wall of the ball screw.

[0022] Furthermore, the rotating connection part, the rolling full circle part and the conical surface perforated part are an integrated structure, the rotating connection part is fixed between two supporting bearing inner rings, the conical surface perforated part is an overall conical structure, and the transition part between the conical surface perforated part and the rolling full circle part is an arc shape.

[0023] Through the above technical scheme, by designing the conical perforated portion to be a conical structure, and designing the transition portion between the conical perforated portion and the rolling full circle portion to be an arc shape, the conical perforated portion is easier to insert into and penetrate the inner hole of the tank body to be processed, and at the same time, the extrusion and friction between the rolling full circle portion and the end of the tank body to be processed can be reduced; the outer diameter of the rolling full circle portion is slightly smaller than the inner diameter of the tank body to be processed, and when the rolling full circle portion is inserted into the inner hole of the tank body to be processed, it can play a certain pre-extrusion and shaping role on the inner hole of the tank body to be processed.

[0024] Furthermore, a plurality of evenly distributed U-shaped grooves are provided on the circumferential side of the rolling full-circle portion, a plurality of the U-shaped grooves are rotatably connected with full-circle rotating rollers, and a plurality of the U-shaped grooves have rounded corners on the circumferential sides of the openings.

[0025] Through the above technical scheme, when the rolling full circle part is completely inserted into the tank body to be processed, multiple full circle rotating rollers will also contact the inner wall of the tank body to be processed. At this time, the second servo motor will drive the rotating connection part, the rolling full circle part and the conical perforated part to rotate synchronously. While the rolling full circle part revolves, it will also drive the synchronous rotation of multiple full circle rotating rollers, so that the inner wall of the tank body to be processed can be fully rolled and shaped by multiple evenly distributed full circle rotating rollers, so that the circumferential side of the inner wall of the tank body to be processed can be evenly stressed, plastically deformed under the rotating rolling state, and finally form a more regular perfect circle; further, since the inner diameter of the first positioning mold and the second positioning mold after the mold is combined is the same as the outer diameter of the tank body to be processed, the tank body to be processed can be fixed and limited from the outside, thereby preventing the welding part from breaking during the rounding process of the tank body to be processed.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention designs a full-circle positioning mechanism for the can body, so that the first positioning mold and the second positioning mold can be opened and closed, thereby realizing the positioning and limiting of the can body to be processed. Since the inner diameter of the first positioning mold and the second positioning mold after the mold is closed is the same as the outer diameter of the can body to be processed, the extrusion correction of the can body to be processed can also be realized from the outside; (2) The present invention designs a rotary drive mechanism and a rotary full-circle mechanism. While the rolling full-circle part revolves, it also drives multiple full-circle rotating rollers to rotate synchronously, so that multiple evenly distributed full-circle rotating rollers can be used. The rotating roller performs all-round rolling and shaping on the inner wall of the tank body to be processed, so that the circumferential side of the inner wall of the tank body to be processed can be evenly stressed, undergoes plastic deformation under the rotating rolling state, and finally forms a more regular perfect circle; (3) The present invention adopts the method of internal and external coordination to jointly act on the circumference of the tank body to perform rounding correction, which can not only achieve a better rounding correction effect, but also the tank body rounding positioning mechanism can fix and limit the tank body to be processed from the outside, thereby preventing the welding part from breaking during the rounding process of the tank body to be processed, thereby ensuring the processing quality and stability during the processing.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] like Figure 1-Figure 16As shown, a large tank body rounding equipment of the present embodiment comprises a processing platform 1, and a tank body rounding positioning mechanism 2 for processing a tank body 8 to be processed is installed on one side of the top of the processing platform 1, and the tank body rounding positioning mechanism 2 comprises a support seat 201, and a first positioning mold 203 and a second positioning mold 204 are rotatably connected to the support seat 201, and a horizontally arranged rotating support shaft 202 is installed on the support seat 201, and the first positioning mold 203 and the second positioning mold 204 are both rotatably connected to the rotating support shaft 202, and the first positioning mold 203 and the second positioning mold 204 are respectively provided with a first limiting protrusion 205 and a second limiting protrusion 206 on both sides of the inner wall. A rotating support 207 is fixedly connected to the outer center position of a positioning mold 203 and a second positioning mold 204. The first positioning mold 203 and the second positioning mold 204 can be opened and closed under the drive of the hydraulic opening and closing mechanism 3. When processing the tank body, the tank body 8 to be processed can be hoisted between the first positioning mold 203 and the second positioning mold 204, and then the first positioning mold 203 and the second positioning mold 204 are closed to achieve positioning and limiting of the tank body 8 to be processed. The inner diameter of the first positioning mold 203 and the second positioning mold 204 after closing is the same as the outer diameter of the tank body 8 to be processed, so that the tank body 8 to be processed can also be squeezed and corrected from the outside.

[0046] like Figure 1-Figure 10 As shown, the support seat 201 and the rotating support shaft 202 can play a role of rotational support for the first positioning mold 203 and the second positioning mold 204, so that the first positioning mold 203 and the second positioning mold 204 can be rotated and opened and closed under the control of the hydraulic opening and closing mechanism 3. When it is necessary to perform full-circle processing on the tank body 8 to be processed, the tank body 8 to be processed can be hoisted between the first positioning mold 203 and the second positioning mold 204 by hoisting equipment, and then the first positioning mold 203 and the second positioning mold 204 are driven by the hydraulic opening and closing mechanism 3 to close the mold, thereby fixing the tank body 8 to be processed between the first positioning mold 203 and the second positioning mold 204. After the full-circle processing is completed, the hydraulic opening and closing mechanism 3 drives the first positioning mold 203 and the second positioning mold 204 to open the mold.

[0047] Furthermore, in this embodiment, the first positioning mold 203 and the second positioning mold 204 are both provided with multiple groups of uniformly distributed transverse reinforcing ribs and longitudinal reinforcing ribs, and the thickness of the first limiting protrusion 205 and the second limiting protrusion 206 is less than the thickness of the tank body 8 to be processed. The multiple groups of uniformly distributed transverse reinforcing ribs and longitudinal reinforcing ribs can further enhance the overall strength of the first positioning mold 203 and the second positioning mold 204. In addition, since the thickness of the first limiting protrusion 205 and the second limiting protrusion 206 is less than the thickness of the tank body 8 to be processed, when the first positioning mold 203 and the second positioning mold 204 are molded, the first limiting protrusion 205 and the second limiting protrusion 206 can both limit the two ends of the tank body 8 to be processed and prevent the rotating full circle mechanism 7 from penetrating into or moving out of the inner hole of the tank body 8 to be processed and squeezing it out of the tank body full circle positioning mechanism 2. At the same time, the first limiting protrusion 205 and the second limiting protrusion 206 will not affect the rotating full circle mechanism 7 from penetrating and squeezing the inner wall of the tank body 8 to be processed.

[0048] like Figure 1-Figure 7 As shown, a hydraulic opening and closing mechanism 3 for opening and closing the first positioning mold 203 and the second positioning mold 204 is also provided on the same side of the processing platform 1; the hydraulic opening and closing mechanism 3 includes two positioning grooves 301 opened at the front and rear ends of one side of the top of the processing platform 1, and the bottoms of the two positioning grooves 301 are rotatably connected to the opening and closing hydraulic cylinders 302, and the top ends of the piston rods of the two opening and closing hydraulic cylinders 302 are fixedly connected to the rotating sleeves 303, and the two rotating sleeves 303 are rotatably connected to the corresponding rotating supports 207 respectively. The two opening and closing hydraulic cylinders 302 can drive the first positioning mold 203 and the second positioning mold 204 to open and close the molds by extending and retracting the piston rods.

[0049] like Figure 1-Figure 5 As shown, a support guide mechanism 4 is fixedly connected to the other side of the top of the processing platform 1, and the support guide mechanism 4 includes two guide brackets 401 fixed to the top of the processing platform 1, and guide rods 402 are fixedly connected to the two guide brackets 401. A connecting rod 403 is also fixedly connected to the side of the two guide brackets 401 away from the tank body full circle positioning mechanism 2. The two guide brackets 401 can play a supporting role, and the guide rods 402 on the two guide brackets 401 can guide and limit the lateral movement of the rotating drive mechanism 6 to ensure that during the processing, the rotating full circle mechanism 7 at one end of the rotating drive mechanism 6 can accurately penetrate the tank body 8 to be processed. In addition, the connecting rod 403 fixedly connected between the two guide brackets 401 can further enhance the connection strength between the two guide brackets 401 and the stability of the support.

[0050] like Figure 5As shown, a servo pushing mechanism 5 is also provided at the center position of the top of the processing platform 1; the servo pushing mechanism 5 includes a first bearing seat 501 and a second bearing seat 502 fixed on the top of the processing platform 1, and a ball screw 503 is rotatably connected between the first bearing seat 501 and the second bearing seat 502. A mounting groove 504 is provided on the side of the top of the processing platform 1 away from the tank body full circle positioning mechanism 2, and a first servo motor 505 is installed in the mounting groove 504. The output shaft of the first servo motor 505 is fixedly connected to one end of the ball screw 503. The servo pushing mechanism 5 is used to drive the rotary drive mechanism 6 to reciprocate in the horizontal direction. When the first servo motor 505 is working, the ball screw 503 can be driven to rotate synchronously through its output shaft, so that the entire rotary drive mechanism 6 and the rotating full circle mechanism 7 can be driven to move horizontally through the ball nut seat 605, including driving the rotating full circle mechanism 7 to insert into the tank body 8 to be processed for full circle processing through the rotary drive mechanism 6, and after the processing is completed, the rotary drive mechanism 6 drives it to move out of the tank body 8 to be processed.

[0051] like Figure 1-Figure 16 As shown, a rotation drive mechanism 6 is slidably connected to the support guide mechanism 4, and the rotation drive mechanism 6 includes a moving base 601, and the front and rear ends of the outer wall of the moving base 601 are respectively fixedly connected with two first guide seats 602 and two second guide seats 603, and the centers of the first guide seats 602 and the second guide seats 603 are provided with guide holes 604. A ball nut seat 605 is also fixedly installed at the bottom of the moving base 601, and the two first guide seats 602 and the two second guide seats 603 are respectively slidably connected to the outer walls of the corresponding connecting rods 403, and the ball nut seat 605 is sleeved on the outer wall of the ball screw 503. An end cover plate 606 is installed at one end of the moving base 601 away from the tank body full circle positioning mechanism 2, and the moving base 601 A cavity 607 is provided inside, and a mounting plate 608 is fixedly connected to the cavity 607. Two supporting bearings 609 are installed on one side of the cavity 607. A second servo motor 610 is installed on one side of the mounting plate 608. The output end of the second servo motor 610 passes through the mounting plate 608 and is fixedly connected to a mounting disk 611. The movable base 601 can move horizontally under the drive of the servo pushing mechanism 5. When the movable base 601 drives the rotating full-circle mechanism 7 to be inserted into the inner hole of the tank body 8 to be processed, the output shaft of the second servo motor 610 will start to rotate, and then the entire rotating full-circle mechanism 7 can be driven to rotate in the tank body 8 to be processed through the mounting disk 611, thereby realizing the full-circle correction of the inner hole of the tank body 8 to be processed.

[0052] like Figure 1-Figure 16As shown, a rotating full circle mechanism 7 is installed at one end of the rotating drive mechanism 6 close to the tank body full circle positioning mechanism 2. The rotating full circle mechanism 7 includes a rotating connection part 701, a rolling full circle part 702 and a conical perforation part 703. The rolling full circle part 702 and the conical perforation part 703 penetrate the tank body 8 to be processed in the processing state, and rotate and roll the inner hole of the tank body 8 to be processed under the drive of the rotating drive mechanism 6.

[0053] Furthermore, in this embodiment, the rotating connection part 701, the rolling round part 702 and the tapered perforated part 703 are an integrated structure, the rotating connection part 701 is fixed between the inner rings of the two support bearings 609, the tapered perforated part 703 is an overall conical structure, and the transition part between the tapered perforated part 703 and the rolling round part 702 is an arc shape. By designing the tapered perforated part 703 to be a conical structure, and designing the transition part between the tapered perforated part 703 and the rolling round part 702 to be an arc shape, the tapered perforated part 703 is easier to insert and penetrate the inner hole of the tank body 8 to be processed, and at the same time, the extrusion and friction between the rolling round part 702 and the end of the tank body 8 to be processed can also be reduced; the outer diameter of the rolling round part 702 is slightly smaller than the inner diameter of the tank body 8 to be processed. When the rolling round part 702 is inserted into the inner hole of the tank body 8 to be processed, it can play a certain pre-extrusion and shaping role on the inner hole of the tank body 8 to be processed.

[0054] In this embodiment, a plurality of evenly distributed U-shaped grooves 7021 are provided on the circumference of the rolling full circle portion 702, and a plurality of U-shaped grooves 7021 are rotatably connected with full circle rotating rollers 7022. The circumference of the openings of the plurality of U-shaped grooves 7021 are all rounded 7023. When the rolling full circle portion 702 is fully inserted into the tank body 8 to be processed, the plurality of full circle rotating rollers 7022 will also contact the inner wall of the tank body 8 to be processed. At this time, the second servo motor 610 will drive the rotating connection portion 701, the rolling full circle portion 702 and the conical perforated portion 703 to rotate synchronously. While the rolling full circle portion 702 is revolving, it will also drive the plurality of The full-circle rotating rollers 7022 rotate synchronously, so that the inner wall of the tank body 8 to be processed can be subjected to all-round rolling and shaping by using a plurality of evenly distributed full-circle rotating rollers 7022, so that the inner wall of the tank body 8 to be processed can be evenly stressed, undergoing plastic deformation under the rotating rolling state, and finally forming a more regular perfect circle; further, since the inner diameter of the first positioning mold 203 and the second positioning mold 204 after mold closing is the same as the outer diameter of the tank body 8 to be processed, the tank body 8 to be processed can be fixed and limited from the outside, thereby preventing the welding part from breaking during the full-circle process of the tank body 8 to be processed.

[0055] The working principle of this embodiment is as follows: when the tank body 8 to be processed needs to be processed in a round shape, the tank body 8 to be processed can be hoisted between the first positioning mold 203 and the second positioning mold 204 by hoisting equipment, and then the first positioning mold 203 and the second positioning mold 204 are driven by the hydraulic opening and closing mechanism 3 to close the mold, thereby fixing the tank body 8 to be processed between the first positioning mold 203 and the second positioning mold 204;

[0056] At this time, the first servo motor 505 starts to work, and the first servo motor 505 drives the ball screw 503 to rotate synchronously through its output shaft, so that the entire rotary drive mechanism 6 and the rotating full circle mechanism 7 can be driven to move horizontally through the ball nut seat 605, so as to slowly push the rotating full circle mechanism 7 into the interior of the tank body 8 to be processed;

[0057] When the mobile base 601 drives the rotating full circle mechanism 7 to be inserted into the inner hole of the tank body 8 to be processed, the output shaft of the second servo motor 610 will start to rotate, and then the entire rotating full circle mechanism 7 can be driven to rotate in the tank body 8 to be processed through the mounting plate 611. While the rolling full circle part 702 is revolving, it will also drive the multiple full circle rotating rollers 7022 to rotate synchronously, so that the multiple evenly distributed full circle rotating rollers 7022 can be used to perform all-round rolling shaping on the inner wall of the tank body 8 to be processed, so that the inner wall of the tank body 8 to be processed can be evenly stressed, plastically deformed in the rotating rolling state, and finally formed into a more regular perfect circle;

[0058] When the full circle processing is completed, the servo push mechanism 5 drives the rotary drive mechanism 6 to drive the rotating full circle mechanism 7 to reset, and then the hydraulic opening and closing mechanism 3 drives the first positioning mold 203 and the second positioning mold 204 to open the mold. At this time, the processed tank body can be hoisted out by hoisting equipment, thereby completing the entire processing process.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
