Description

Technical Field

[0001] The present application relates to the technical field of parts processing, and in particular to a correction device and method for the distortion and deformation of a cone plate. Background Art

[0002] Conical plates are used in shipbuilding, and plate rolling machines are usually used for processing. The plate rolling machine rolls the conical workpiece by generating resistance through the contact between the baffle wheel and the small end face of the cone plate, which slows down the rolling of the small end of the cone plate and shortens the rolled arc segment. Under normal circumstances, the ratio of the arc length of the large end of the rolled cone plate to the arc length of the small end of the rolled cone plate remains unchanged in the same time, thus ensuring that the generatrix of the cone formed by the rolled cone plate is evenly distributed.

[0003] Since the resistance generated by the contact between the baffle wheel of the plate rolling machine and the small end face of the cone plate is related to many factors, the resistance generated by the contact between the baffle wheel and the small end face of the cone plate will change. The change in the resistance will change the rolling speed of the small end of the cone plate, affecting the uniform distribution of the generatrix of the formed cone, generating a helical angle and causing the cone plate to twist and deform. Figure 1 As shown in the figure, when the resistance of the blocking wheel is large, the small end of the cone plate moves too slowly, and the actual busbar A2B3 and the ideal busbar A3B3 produce a left-hand angle; when the resistance of the blocking wheel is small, the small end of the cone plate moves too fast, and the actual busbar A4B3 and the ideal busbar A3B3 produce a right-hand angle. Because the cone plates at the twisted and deformed parts cannot be spliced, the flatness and quality of the splicing parts of several cone plates cannot be guaranteed, so the twisting and deformation of the cone plates must be corrected before splicing.

[0004] For shell plates and cone plates with higher quality requirements, non-indentation hanging clamps are required. Non-indentation hanging clamps require stable workpiece hoisting. When there is impact or shaking during the hoisting process, this non-indentation hanging clamp is easy to detach from the hanging workpiece shell plate and cone plate.

[0005] In the related technology, the cone plate distortion correction process is mainly completed by using a 2500-ton hydraulic press a, an upper mold b, a lower mold c, a non-indentation vertical hanging clamp e, a crane d and a corresponding sling f to form a 2500-ton hydraulic press cone plate distortion correction system (refer to Figure 2 ). The specific method is as follows: The distortion correction process is to first place the distorted cone plate on the lower die of the 2500-ton hydraulic press, and then deflect the distorted cone plate in the reverse spiral direction for a certain angle (the upper and lower dies of the 2500-ton hydraulic press do not need to rotate at this time). At this time, the axis of the upper and lower dies of the 2500-ton hydraulic press forms an anti-helical angle with the generatrix of the cone plate, so that the oil cylinder of the 2500-ton hydraulic press drives the upper die to press down, forming a conical generatrix close to the theory on the cone plate.

[0006] However, when the oil cylinder of the 2500-ton hydraulic press drives the upper die to press down, the pressed cone plate will shake. Since the non-indentation type hanging clamp has no self-locking function, the shaking of the cone plate will cause the hanging clamp and the cone plate to loosen. The hanging clamp and the cone plate are in a loose state. When the oil cylinder of the 2500-ton hydraulic press drives the upper die to lift, the clamping effect on the lower end of the cone plate disappears after the upper die is lifted. At this time, the hanging clamp on the upper part of the cone plate is in an unconstrained loose state, and the safety anti-dumping system composed of the crane, lifting slings and the hanging clamp with tooth marks fails. Since the suspended cone plate has no high-altitude support mechanism to support it, it will inevitably cause the cone plate to tip over, posing a serious safety accident hazard. Summary of the invention

[0007] The embodiments of the present application provide a cone plate distortion correction device and method to solve the problem that the cone plate distortion correction system in the related art has great potential safety hazards.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] At present, the cone plate distortion correction can be carried out by using a 500-ton shell ring correction machine. The difference between it and the 2500-ton hydraulic press correction cone plate distortion system is as follows:

[0034] The 500-ton shell ring correction machine is a vertical correction method for distortion correction; the 2500-ton hydraulic press cone plate distortion correction system is a horizontal correction method relative to the workpiece correction method.

[0035] The rotation of the head on the pressure head installation mechanism of the 500-ton shell ring correction machine by one angle is equivalent to the deflection of the cone plate workpiece along the axis of the lower die of the 2500-ton hydraulic press by one angle.

[0036] The 2500-ton hydraulic press's cone plate distortion correction system does not have a high-altitude support mechanism, and is prone to tipping over when using a traceless clamp. When the 500-ton shell ring correction machine corrects the distorted cone plate, the cone plate is hung between the left and right main frames, and the 500-ton shell ring correction machine applies force to correct the cone plate. At this time, the left and right main frames support the cone plate and prevent it from tipping over.

[0037] When the 2500-ton hydraulic press corrects the cone plate distortion and deformation system, the crane clamps and lifts one end of the cone plate through the wire rope sling and the vertical clamp. During the lifting process, the center of gravity of the cone plate changes position all the time. In order to adapt to the change of the center of gravity of the cone plate, the trolley of the crane must also move and change with the displacement of the center of gravity of the cone plate. This process is very slow. At the same time, during the correction process, the cone plate also needs the lifting of the crane to move the cone plate to the position of the lower die of the 2500-ton hydraulic press. This process is also very slow. When the 500-ton shell ring correction machine corrects the distorted cone plate, the lifting action of the crane is not required. The lifting and lowering of the lifting cylinder replaces the lifting and coordination work of the crane. There is no need for the crane to cooperate with the lifting of the cone plate to change its position on the lower die. The inclination angle of the top pressure head is adjusted before correction. Therefore, a lot of lifting and coordination time is reduced when the 500-ton shell ring correction machine is used to correct the distorted cone plate.

[0038] When the cone plate workpiece is deflected at an angle along the lower die of the 2500-ton hydraulic press, one end of the 2500-ton lower die will form a linear contact with the cone plate, and the other end of the lower die will form a point contact with the cone plate; the pressure head of the 500-ton shell ring correction machine is always between the two top blocks (the top blocks are not arranged along the height direction of the main frame) during the correction of the workpiece, thus forming a complete constraint, which is easy to cause the workpiece to bend when correcting the distortion, forming positive stress and causing linear deformation of the workpiece. This is different from the 2500-ton hydraulic press correction system for cone plate distortion, and it is also the reason why the 500-ton shell ring correction machine must be improved when correcting distortion.

[0039] The mold length of the 2500-ton hydraulic press's cone plate distortion correction system is 3000mm, which completely covers the processing range of distorted workpieces. During the correction process, one end of the lower mold forms axial line contact with the cone plate; while the top pressure head of the pressure head installation mechanism of the 500-ton shell ring correction machine is 300mm long and has no axially arranged support block, so it cannot form axial line contact with the cone plate.

[0040] If a corresponding space cone plate support and clamping system is added to the cone plate distortion correction system of a 2500-ton hydraulic press, a huge high-altitude support system and clamping device will need to be added. There is no corresponding successful example of this system, and the system occupies a large space and is very expensive.

[0041] Based on the above analysis, and comparing the shortcomings of the cone plate distortion correction system using a 500-ton shell ring correction machine and a 2500-ton hydraulic press, the following innovative solution for the distortion correction of a 500-ton shell ring correction machine is proposed.

[0042] The embodiments of the present application provide a device and method for correcting the distortion of a cone plate, which can solve the problem that the current system for correcting the distortion of a cone plate has great potential safety hazards.

[0043] On the one hand, referring to Figure 3-6 As shown, this embodiment provides a correction device for the distortion of a cone plate, comprising a frame, a rotatable pressure head 3 and at least three adjustment mechanisms 5, wherein the frame comprises a first frame 1 and a second frame 2 arranged opposite to each other, the pressure head 3 is lifted and lowered on the first frame 1 and can move closer to or away from the second frame 2, at least three adjustment mechanisms 5 are arranged on the second frame 2 and distributed in the vertical direction, at least one adjustment mechanism 5 can be lifted and lowered on the second frame 2, and a top block 6 is provided on the adjustment mechanism 5.

[0044] Reference Figure 3 and Figure 4 Specifically, a pressure head installation mechanism 4 is provided on the first frame 1, and the pressure head installation mechanism 4 includes a pressure head seat 401 and a connecting seat 402. The pressure head seat 401 is located between the first frame 1 and the second frame 2, and the connecting seat 402 is vertically slidably installed in the first frame 1. One end of the connecting seat 402 is fixed to the pressure head seat 401, and the other end passes through the side of the first frame 1 away from the second frame 2, and two limit blocks attached to the first frame 1 are connected to the opposite sides of the connecting seat 402 away from the end of the pressure head seat 401. The limit blocks are used to limit the connection seat 402 from moving toward the second frame 2. Through the cooperation of the limit blocks and the pressure head seat 401, the connection seat 402 can be stably lifted and lowered vertically on the first frame 1; at the same time, a first oil cylinder for driving its upgrade is provided below the connecting seat 402 in the first frame 1.

[0045] The pressure head 3 is installed on the side of the pressure head seat 401 facing the second frame 2, and an active oil cylinder is installed in the connection seat 402, with its piston rod facing the second frame 2. The pressure head 3 is installed on a rotating interface sleeve 403, and the rotating interface sleeve 403 is connected to the piston rod of the active oil cylinder. In this way, the pressure head 3 can be rotated and driven to move close to the second frame 2 to apply pressure to the cone plate to correct the distortion.

[0046] Reference Figure 4Specifically, the rotating structure sleeve may be composed of a rotating disk 4031 and a mounting block 4032, the mounting block 4032 being fixed on the piston rod of the active oil cylinder, the rotating disk 4031 being rotatably mounted on the mounting block 4032 through a rotating shaft, the pressure head 3 being fixed on the rotating disk 4031, and being fixed after the pressure head 3 rotates, a fixing bolt that abuts against the mounting block 4032 may be installed on the rotating disk 4031, and the rotating disk 4031 and the pressure head 3 are fixed by tightening the mounting block 4032 with the fixing bolt. Other rotating mounting and fixing structures may also be selected in other embodiments.

[0047] Reference Figure 4 Two support blocks 404 are arranged on one side of the pressure head seat 401 facing the second frame 2. The two support blocks 404 are distributed in a horizontal direction and perpendicular to the moving direction of the pressure head 3. The two support blocks 404 are respectively located on both sides of the pressure head 3. The two support blocks 404 support the cone plate from both sides of the pressure head 3 during calibration, so as to improve the stability of the cone plate during calibration and improve the calibration accuracy of the cone plate.

[0048] Furthermore, the sides of the pressure head 3, the support block 404 and the top block 6 that are in contact with the cone plate are all configured as arc surfaces that match the cone plate.

[0049] Reference Figure 5 and Figure 6 The adjustment mechanism 5 includes a top block support 501 and a connector 502. The top block support 501 is arranged between the first frame 1 and the second frame 2, and the connector 502 is arranged in the second frame 2. One end of the connector 502 is connected to the top block support 501, and the other end passes through the side of the second bracket away from the first bracket. The connector 502 is installed with angle brackets 503 on both sides of the end away from the top block support 501 to limit its movement close to the first frame 1. The angle bracket 503 is fitted with the second frame 2 through a composite rear guide plate 504, and a composite front guide plate 505 is provided between the top block support 501 and the second frame 2 bracket. The top block support 501 is fitted with the second frame 2 through the composite front guide plate 505, so that the top block support 501 and the angle bracket 503 can cooperate to limit the connection body 502 from being separated from the second frame 2, and the connection body 502 and the top block support 501 can be lifted and lowered on the second frame 2.

[0050] Reference Figure 3 Furthermore, three adjustment mechanisms 5 are provided, and the adjustment mechanisms 5 include a top block support 501 and a connector 502. The three adjustment mechanisms 5 are respectively an upper adjustment mechanism 7, a middle adjustment mechanism 8 and a lower adjustment mechanism 9 on the second frame 2 from top to bottom.

[0051] Reference Figure 3The lower adjustment mechanism 9 is installed at the bottom of the second frame 2 and is fixed, while the upper adjustment mechanism 7 and the middle adjustment mechanism 8 are connected by bolts and can be raised and lowered on the second frame 2 through a second oil cylinder; specifically, the second oil cylinder is installed on the lower adjustment mechanism 9 and is located in the second frame 2.

[0052] Reference Figure 3 Further, one top block 6 is respectively provided on the upper adjustment mechanism 7 and the lower adjustment mechanism 9, and two top blocks 6 are provided on the middle adjustment mechanism 8, and the top blocks 6 on the upper adjustment mechanism 7 and the lower adjustment mechanism 9 are movably provided, and the moving direction of the top blocks 6 is horizontal and perpendicular to the direction in which the pressure head 3 moves toward or away from the second frame 2, while the two top blocks 6 on the middle adjustment mechanism 8 are fixed and located on both sides of the top block support 501 in the middle adjustment mechanism 8; by setting four top blocks 6, when the cone plate having a right spiral line is twisted and corrected The three top blocks 6 in the upper adjustment mechanism 7 and the middle adjustment mechanism 8 can constitute an incompletely constrained distortion correction fulcrum to facilitate correction. When the cone plate with a left spiral is subjected to distortion correction, the three top blocks 6 in the middle adjustment mechanism 8 and the lower adjustment mechanism 9 can constitute an incompletely constrained distortion correction fulcrum to facilitate correction. The horizontal positions of the top blocks 6 on the upper adjustment mechanism 7 and the lower adjustment mechanism 9 can be adjusted to adjust the position of the distortion deformation of the cone plate, so that the upper and lower top blocks 6 can provide good support for the cone plate.

[0053] The working areas of the pressure head 3 on the first frame 1 are the upper adjustment mechanism area and the lower adjustment mechanism area. Since correction in these two areas will not form bending force or bending stress on the cone plate, the linear change or change of the cone plate can be avoided. When the pressure head 3 presses the cone plate in the upper adjustment mechanism 7 area, the lower part of the cone plate will be displaced in the opposite direction of the pressure of the pressure head 3 under the action of the middle fulcrum until the correction distortion is eliminated. Conversely, when the pressure head 3 presses the cone plate in the lower adjustment mechanism 9 area, the upper part of the cone plate will be displaced in the opposite direction of the pressure of the pressure head 3 under the action of the middle fulcrum until the correction distortion is eliminated.

[0054] Reference Figure 3 Specifically, mounting grooves are provided on the top block supports 501 of the upper adjustment mechanism 7 and the lower adjustment mechanism 9, and a transmission screw 506 is rotatably installed in the mounting grooves. The top block 6 is installed in the mounting grooves and protrudes out of the mounting grooves. The upper and lower sides of the top block 6 are respectively attached to the inner walls of the opposite sides of the mounting grooves, and the top block 6 is assembled on the transmission screw 506 through a nut; thereby, the movement of the top block 6 can be controlled by rotating the transmission screw 506, and the position of the top block 6 can be locked. For the convenience of control, one end of the transmission screw 506 passes through the top block support 501 and is connected to a hand crank.

[0055] Furthermore, rollers can be installed on the ground on both sides of the frame, with their axes horizontal and driven to rotate by a motor. They can support the cone plate when the cone plate is adjusted between the first frame 1 and the second frame 2, and control the cone plate to move between the first frame 1 and the second frame 2.

[0056] Furthermore, the size and material of each part, the moving stroke of the pressure head 3, the adjustment stroke of the top block 6 on the upper adjustment mechanism 7 and the lower adjustment mechanism 9, and the distance between the two top blocks 6 on the middle adjustment mechanism 8, etc., all need to be designed according to actual needs to meet the structural strength and size required for cone plate correction.

[0057] The implementation principle of this embodiment is as follows: when correcting the cone plate, first, the cone plate to be twisted and deformed is moved between the first frame 1 and the second frame 2, the bottom of the cone plate is placed on the roller, and after it is firmly placed, the sling is removed, and the positions of the four top blocks 6 on the three adjustment mechanisms 5 are adjusted, and then the pressure head 3 is rotated to adjust the inclination of the pressure head 3, and the height of the pressure head 3 is adjusted, and the pressure head 3 is controlled by the active cylinder to move toward the second frame 2 to apply pressure to the cone plate for reverse correction of the twisting deformation, and the force exerted on the top block 6 is transmitted to the second frame 2, and the anti-helix direction correction method is adopted to make the ascending part of the spiral line of the twisted and deformed cone plate become the descending part, and the descending part of the spiral line become the ascending part, thereby converting it into a longitudinal theoretical generatrix, and stopping the correction after achieving the anti-deformation correction effect, and after releasing the active cylinder, repeat the correction in the same way on the rotating cone plate until the correction is complete.

[0058] On the other hand, an embodiment of the present application further provides a method for correcting the distortion of a cone plate, which uses the above-described device for correcting the distortion of a cone plate to perform correction.
