Description

Technical Field

[0001] The invention relates to the technical field of manufacturing super-large head plates, and in particular to a super-large head plate integral pressing and forming device. Background Art

[0002] The head plate is a semicircular or fully circular plate used for the heads of pipes and containers. Its main function is to close the openings of pipes and containers, and play a role in sealing, heat preservation and heat insulation. Head plates are widely used in pressure vessels, tank trucks, reactors and other equipment in the chemical, petroleum, pharmaceutical, food, metallurgical and other industries, while super-large head plates are usually used in large containers and equipment.

[0003] In the field of modern industrial manufacturing, especially in the petrochemical, aerospace and heavy machinery manufacturing industries, super-large head plates are key components of pressure vessels, storage tanks and various large equipment. Their manufacturing quality is directly related to the safety and reliability of the entire system. However, as a super-large workpiece, super-large head plates have some difficulties in the process of pressing, forming and transportation:

[0004] 1. The super-large head plate is large in size, so it cannot be completed by a one-time molding method. Instead, it needs to go through thousands of point pressing to gradually form it. During pressing, the workpiece needs to be rotated after each point pressing to ensure that its circumference is fully pressed. However, the super-large head plate is large in size and heavy in weight. Such frequent adjustments bring great challenges. If it is operated manually, not only is the labor intensity huge, but it is also very easy to cause incomplete pressing due to manual errors, which will affect the molding quality;

[0005] 2. The opening diameter of the super-large head plate is very large, so during the process of hoisting and transferring the head between processes, the head as a whole, especially the opening, is prone to deformation;

[0006] 3. Due to the large curvature of the lower spherical surface of the super-large head plate, coupled with the inevitable process defects in the pressing process, such as uneven pressing force leading to excessive extension of the material, high concentration of internal stress of the material under high temperature and high pressure, etc., it is easier to cause defects such as bulging, wrinkling and cracks, thereby reducing the molding quality. However, due to the shape characteristics of the super-large head plate, manual operation is inconvenient and repair work is more difficult. Summary of the invention

DETAILED DESCRIPTION

[0058] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0059] like Figure 1-10 As shown, a super-large head plate integral pressing and forming device comprises: a base surface 1, a point pressing machine 2, a hoisting device 3 and a processing seat 4 located on the base surface 1, a head plate 5 arranged on the processing seat 4, and the head plate 5 is located below the pressing end of the point pressing machine 2, a rotating part 6 arranged on the base surface 1, a repairing part 7 located on the base surface 1, and a solid mechanism 8 installed on the hoisting device 3;

[0060] The rotating part 6 is located below the head plate 5 and is attached to the back side of the head plate 5, wherein:

[0061] The point press machine 2 is suitable for reciprocating point pressing of the head plate 5, and the hoisting device 3 is suitable for hoisting and transferring the head plate 5;

[0062] The rotating portion 6 is suitable for tightly adsorbing the head plate 5 to be integrated with the head plate 5;

[0063] The rotating part 6 is driven to swing quantitatively in the circumferential direction to cause the head plate 5 to rotate slightly;

[0064] The repairing portion 7 is adapted to extend into the head plate 5 and fit the inner wall thereof to repair the defect;

[0065] The solid forming mechanism 8 is suitable for supporting the opening edge of the head plate 5 at multiple points so that the opening of the head plate 5 can be shaped by external force. The ultra-large head plate integral pressing and forming device can firmly adsorb the head plate 5 through the rotating part 6, and can drive the head plate 5 to rotate to a certain extent in the circumferential direction, so as to achieve the purpose of turning the head plate 5 to adjust its position, and then cooperate with the point press machine 2 to ensure the comprehensive overall pressing of the head plate 5, and ensure that the frequent adjustment of the head plate 5 is completed automatically and accurately, effectively avoiding errors that lead to incomplete pressing of the head plate 5, and can be flexibly moved to the specified position in the head plate 5 through the repair part 7, and can be targetedly formed in the head plate 5 with a variety of repair methods. Common defects can be repaired during the process, which can well adapt to the shape characteristics of the super-large head plate 5, thereby effectively solving the inconvenience in traditional operations and greatly reducing the difficulty of repair. The solid mechanism 8 can be used to carry out targeted reinforcement of the openings of the super-large head plate 5 that are more prone to deformation, thereby forming a reaction force to the force of the lifting equipment 3 acting on the head plate 5, and protecting the head plate 5, thereby effectively preventing the lifting equipment 3 from deforming the head plate 5 when lifting and moving it. The super-large head plate integral pressing and forming device can ensure the steady progress of the key forming steps in the entire forming process of the head plate 5, and can well prevent the occurrence of adverse effects, thereby optimizing the overall forming process and ensuring the forming quality.

[0066] Optionally, the rotating part 6 includes a swing groove 61 opened on the base surface 1, a vertical seat 62 movably installed in the swing groove 61, a plane mounting member 63 mounted on the vertical seat 62, an electromagnetic plate 64 mounted on the plane mounting member 63, a bearing seat 65 arranged on the base surface 1, a shaft 66 vertically mounted on the bearing seat 65, two torsion plates 67 with one end fixedly mounted on the shaft 66 and the other end fixed on the vertical seat 62, and the two torsion plates 67 are arranged opposite to each other, a positioning frame plate 68 mounted on the torsion plate 67 located above, and a motor 69 mounted on the positioning frame plate 68;

[0067] The output shaft of the motor 69 is connected downwardly to the top end of the shaft 66;

[0068] The electromagnetic plate 64 is connected to an external power source via a wire;

[0069] The surface of the electromagnetic plate 64 is arc-shaped, and the electromagnetic plate 64 is attached to the back of the head plate 5. The main raw material of the electromagnetic plate 64 is electromagnet, which is only formed into an arc-shaped plate to fit the back of the head plate 5. When the external power supply is turned on, the electromagnetic plate 64 is energized to generate magnetic force, which tightly adsorbs the metal head plate 5, so that the rotating part 6 and the head plate 5 are connected as a whole by adsorption, and then the motor 69 is driven to rotate the shaft 66 under the action of the bearing seat 65, and then through the two torsion plates 67 drives the vertical seat 62 to move along the swing groove 61 at a corresponding angle, thereby carrying the head plate 5 to rotate at a corresponding amplitude, so as to achieve the purpose of turning the head plate 5 to adjust its position. At the same time, the motor 69 is used as the driving force. The rotation amplitude of the head plate 5 is adjustable and can ensure that the rotation amplitude is consistent each time, thereby ensuring that the adjustment of the head plate 5 is completed automatically and accurately to prevent the head plate 5 from having inconsistent rotation amplitudes, resulting in leakage on the head plate 5, resulting in incomplete pressing, and then affecting the molding quality.

[0070] Optionally, the vertical seat 62 includes a lower cylinder 621, a first electric push rod 622 installed on the inner bottom surface of the lower cylinder 621, a load column 623 that fits and slides into the lower cylinder 621, and the output shaft of the first electric push rod 622 is connected to the bottom surface of the load column 623, and a direction adjustment member 624 installed on the top of the load column 623;

[0071] The lower cylinder 621 is movably disposed in the swing slot 61, and a plurality of ventilation slots are provided on the circumference of the lower cylinder 621 to allow external air to flow into the lower cylinder 621 to dissipate heat for the first electric push rod 622;

[0072] The two torsion plates 67 are respectively installed at the upper and lower ends of the lower cylinder 621;

[0073] The planar mounting part 63 is arranged on the adjusting part 624. After the head plate 5 is rotated and adjusted into place, the external power supply is disconnected so that the electromagnetic plate 64 can be separated from the head plate 5. Then, the first electric push rod 622 is driven to pull down the load-bearing column 623 so that the electromagnetic plate 64 is separated from the head plate 5, and the motor 69 is driven in reverse to reset the vertical seat 62. Then, the first electric push rod 622 is driven again to make the electromagnetic plate 64 stick to the head plate 5, and the external power supply is turned on again so that the electromagnetic plate 64 can firmly absorb the head plate 5, so that the head plate 5 can be rotated immediately after the point press machine 2 completes each point press, to ensure smooth cooperation with the point press machine 2 to perform comprehensive and overall pressing of the head plate 5.

[0074] Optionally, the repairing part 7 includes a lower workbench 71, a direction-adjusting seat 72 arranged on the lower workbench 71, a vertical arm 73 connected to the direction-adjusting seat 72, a telescopic rectangular arm 74 connected to the front end of the vertical arm 73, a repairing end 75 installed at the front end of the telescopic rectangular arm 74, a force-bearing baffle 76 installed at the end of the telescopic rectangular arm 74, and a second electric push rod 77 arranged at the top of the vertical arm 73;

[0075] The output shaft of the second electric push rod 77 is connected to the force baffle 76;

[0076] The lower working table 71 is in contact with the base surface 1 through a number of universal wheels at the bottom. After the point press 2 fully completes the point pressing of the head plate 5 to make it initially formed, the load-bearing column 623 is lowered to the lowest position through the first electric push rod 622, and the point press 2 is reset to retract its pressing end, and then the head plate 5 is straightened on the processing seat 4; specifically, the telescopic rectangular arm 74 is composed of a number of rectangular arms that are slidably connected in sequence, and the force baffle 76 and the repair end 75 are installed on the last rectangular arm. By continuously driving the second electric push rod 77, several sections can be pulled out in sequence, so that the telescopic rectangular arm 74 is gradually unfolded, and through a number of universal wheels at the bottom of the lower working table 71 The repair part 7 can be flexibly moved as a whole on the base surface 1, and can be moved accordingly according to the specific location of the defective part, thereby ensuring that the repair end 75 can be accurately delivered to any position in the head plate 5 for defect repair. It is well adapted to the shape characteristics of the super-large head plate 5, effectively solves the inconvenience in traditional operations, and greatly reduces the difficulty of repair. Several universal wheels use products with self-locking function. When repairing defects, several universal wheels are locked to fix the repair part 7 as a whole in the current position to prevent the repair end 75 from deviating from the position where the defect occurs due to the force generated by the hydraulic cylinder 752 or the displacement of the repair part 7 due to other circumstances during subsequent repairs.

[0077] Optionally, the repair end 75 includes a panel 751 connected to the front end of the telescopic rectangular arm 74, a hydraulic cylinder 752 and a chuck 753 installed in the same direction on the panel 751, and a pressing piece 754 installed on the output end of the hydraulic cylinder 752;

[0078] The hydraulic cylinder 752 is installed on the panel 751 with the output end facing downward. When there is a bulging defect, after aligning the top pressure piece 754 with the bulging position, the hydraulic cylinder 752 is driven to push the top pressure piece 754 to gradually move toward the bulging position, and the bulge is gradually pushed back and removed by the force of the hydraulic cylinder 752. When a relatively minor crack or wrinkle appears, a suitable processing device, generally a grinder, is first selected and installed on the chuck 753 to complete the fixation, and then the processing device is attached to the crack or wrinkle through a number of universal wheels and a telescopic rectangular arm 74, and then the processing device is driven to gradually grind and eliminate the crack or wrinkle, so that targeted processing can be taken for various defects that may occur in the molding process to ensure that the defects are repaired, the molding quality is guaranteed, and the inconvenience in traditional operations is effectively solved, reducing the difficulty of repair;

[0079] The hydraulic cylinder 752 is located entirely behind the chuck 753. After aligning the pressing piece 754 with the bulge position, continuously driving the hydraulic cylinder 752 can make the pressing piece 754 contact the bulge, while not affecting the repair work of the bulge, ensuring that the hydraulic cylinder 752 and the pressing piece 754 do not protrude from the chuck 753 to prevent interference with the repair work of cracks or wrinkles.

[0080] Optionally, the direction-adjusting seat 72 includes a bottom pier block 721 and a swing cylinder 722 disposed on the lower worktable 71, and the swing cylinder 722 is located on one side of the bottom pier block 721;

[0081] The vertical arm 73 is hinged on the bottom pier block 721;

[0082] The output end of the swing cylinder 722 is connected to the vertical arm 73. Driving the swing cylinder 722 can drive the vertical arm 73 to tilt forward or backward with the hinge point with the bottom pier block 721 as the center of the circle, so as to ultimately achieve the purpose of adjusting the angle of the top pressure piece 754 and the processing equipment installed on the chuck 753, ensuring that the two can be highly fitted with the position where the defect occurs under different circumstances, thereby ensuring the repair effect and preventing additional damage to the head plate 5.

[0083] Optionally, the solid structure 8 includes two right-angled hanging plates 81 installed on the hoisting device 3, an electric winch 82 installed on the two right-angled hanging plates 81, a cable 83 connected to the electric winch 82 at one end, a middle plate 84 connected to the other end of the cable 83, and the middle plate 84 is located directly above the head plate 5 and coaxial with the head plate 5, a plurality of third electric push rods 85 circumferentially installed on the middle plate 84, an outer push rod 86 one end of which is respectively connected to the output shafts of the plurality of third electric push rods 85, and a plurality of inner push rods 87 respectively connected to the other ends of the plurality of outer push rods 86, wherein:

[0084] The plurality of inner push members 87 are suitable for fitting against the inner wall of the head plate 5. When the head plate 5 needs to be hoisted, the electric winch 82 is started to lower the cable 83 continuously until the plurality of inner push members 87 are lowered to a position where they can contact the edge of the opening of the head plate 5, and then the electric winch 82 is stopped, and then the plurality of third electric push rods 85 are synchronously driven to push all the inner push members 87 outward through the plurality of outer push rods 86 until all the inner push members 87 are tightly against the inner wall of the head plate 5, thereby supporting the opening of the head plate 5 from the inside out. , forming a reaction force of the force exerted by the lifting equipment 3 on the head plate 5, and strengthening the opening of the head plate 5 in a targeted manner. When the lifting equipment 3 lifts the head plate 5, a number of fixed inner resistance parts 87 are used to offset the pressure, thereby protecting the vulnerable parts of the head plate 5, and effectively preventing the lifting equipment 3 from causing deformation of the head plate 5 when lifting and moving the head plate 5, thereby ensuring the overall molding quality; after completing the reinforcement of the opening of the head plate 5, the lifting equipment 3 is controlled to lift it and move it to the designated position for subsequent molding processing.

[0085] Optionally, the adjusting member 624 is a damping shaft, so that the planar mounting member 63 can perform passive relative rotation through the adjusting member 624, so that when the first electric push rod 622 pushes the electromagnetic plate 64 to stick to the head plate 5, the electromagnetic plate 64 can self-adjust according to the actual shape of the back of the head plate 5, to ensure that even when the circumferential angle of the head plate 5 changes with the progress of pressing, the electromagnetic plate 64 can still contact the head plate 5 as much as possible to maintain the adsorption effect on the head plate 5, thereby ensuring that the head plate 5 can be carried steadily to rotate. The damping shaft has a certain friction force and can support the relative rotation of objects only under a certain pressure. Therefore, when the circumferential angle of the head plate 5 does not change significantly, the electromagnetic plate 64 can maintain an angle and normally fit with the head plate 5 for multiple times.

[0086] In addition, in another embodiment of the invention, a processing technology of an ultra-large head plate integral pressing forming device is provided, comprising the following steps:

[0087] S1: Place the blank head plate 5 on the processing seat 4 as required, then start the point press 2 to perform cyclical point pressing on the head plate 5. When the point press 2 presses the head plate 5, the external power supply is turned on to energize the electromagnetic plate 64 to generate magnetic force to adsorb the head plate 5. Each time the point press 2 presses downward, the motor 69 is driven once, and the head plate 5 is rotated through the shaft 66, the two torsion plates 67, the vertical seat 62, the plane mounting part 63 and the electromagnetic plate 64 in sequence. Under the cooperation of the rotating part 6 and the point press 2, the circumference of the head plate 5 is fully and cyclically pressed as a whole;

[0088] S2: After the point pressing is completed and the blank head plate 5 is initially formed as a whole, the point pressing machine 2 and the rotating part 6 are reset, and the position of the head plate 5 is adjusted on the processing seat 4, and then the repair part 7 is moved to the corresponding position as a whole according to the specific position of the defects such as bulges, wrinkles and cracks in the head plate 5, and then the second electric push rod 77 drives the telescopic rectangular arm 74 to extend outward, and the adjustment seat 72 drives the vertical arm 73 to tilt until the repair end 75 can contact the defect in the head plate 5;

[0089] S3: When dealing with bulge defects, align the top pressure piece 754 with the bulge position, and then drive the hydraulic cylinder 752 to gradually eliminate the bulge. When dealing with wrinkles and cracks, select the corresponding processing equipment and install it on the chuck 753, then stick the processing equipment on the chuck 753 to the wrinkles and cracks, and start the processing equipment to eliminate the wrinkles and cracks.

[0090] S4: Keep the head plate 5 in a straightened state, start the electric winch 82 to loosen the cable 83 until the inner abutments 87 reach the opening edge of the head plate 5, and then synchronously drive the third electric push rods 85 so that each of them pushes the corresponding inner abutments 87 outwards through the outer push rods 86 until the inner abutments 87 are all tightly pressed against the inner wall of the head plate 5, connect the lifting point of the lifting equipment 3 with the head plate 5, and then lift the head plate 5 through the lifting equipment 3 to transfer it to the designated position to undergo the next molding process.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
