Description

Technical Field

[0001] The present application relates to the technical field of manufacturing low-temperature resistant metal spiral wound gaskets, and in particular to a method, system, terminal and storage medium for manufacturing low-temperature resistant metal spiral wound gaskets. Background Art

[0002] Low-temperature-resistant spiral wound gaskets are primarily used for fluid sealing and are widely used in the petroleum, chemical, shipbuilding, aerospace, and nuclear industries. In the marine engineering sector, thanks to their excellent corrosion resistance, creep resistance, and low-temperature resistance, they are widely used in sealing areas in harsh environments such as submarine pipelines, offshore platforms, and ship power systems. They can effectively withstand extreme operating conditions such as seawater corrosion, high-pressure shock, and drastic temperature fluctuations, providing a key guarantee for the safe operation of marine equipment. Low-temperature-resistant spiral wound gaskets are typically made of low-temperature-resistant metal materials and have excellent low-temperature resistance, capable of maintaining good sealing and structural stability in low-temperature environments.

[0003] A low-temperature-resistant spiral wound gasket consists of an inner ring, a metal strip wrapped around the outer circumference of the inner ring, and a graphite strip. In related art, the inner ring is typically manually secured to a rotating table, and the starting end of the metal strip is then manually welded to the inner ring. After the rotating table is turned to allow the metal strip to wrap several turns, a graphite strip is inserted into the angle between the metal strip and the metal strip wrapped around the inner ring, allowing the two strips to be wound synchronously. Once the graphite strip has been wound to the specified length, the graphite strip is cut and the metal strip is wrapped several turns separately, which is then welded securely.

[0004] Regarding the above-mentioned related technologies, the efficiency of manually producing low-temperature resistant metal spiral wound gaskets is low. Summary of the Invention

[0005] In order to improve the production efficiency of low-temperature resistant metal spiral wound gaskets, the present application provides a method, system, terminal and storage medium for producing low-temperature resistant metal spiral wound gaskets.

[0006] In the first aspect, the present application provides a method for manufacturing a low-temperature resistant metal spiral wound gasket, which adopts the following technical solution:

[0007] A method for manufacturing a low-temperature resistant metal spiral wound gasket, comprising:

[0008] Grab the inner ring by a robot and move it to a preset working position;

[0009] Fixing the starting end of the metal strip to the outer peripheral wall of the inner ring to form a first fixing point;

[0010] controlling the inner ring to rotate and drive the metal belt to be wound, and controlling the inner ring to stop rotating when the number of rotations of the inner ring reaches a first preset value;

[0011] Executing graphite strip feeding, allowing the graphite strip to pass through a feeding zone, and controlling the rotation of the inner ring to allow the graphite strip and the metal strip to be wound synchronously;

[0012] When the number of rotations of the inner ring reaches a second preset value, the inner ring is controlled to stop rotating and the graphite strip is cut off;

[0013] Controlling the inner ring to continue rotating so that the remaining graphite strips are wound;

[0014] Controlling the inner ring to continue rotating to drive the metal belt to be wound separately;

[0015] When the number of rotations of the inner ring reaches a third preset value, controlling the inner ring to stop rotating and cutting the metal strip;

[0016] Controlling the inner ring to continue rotating so that the remaining metal strip is wound;

[0017] Fixing the two outermost layers of the metal strips to form a second fixing point to obtain a low-temperature resistant metal spiral wound gasket;

[0018] The low-temperature resistant metal wound gasket is grabbed by a robot and placed at a preset location.

[0019] By adopting the above technical solution, the inner ring is moved to a preset working position, and the starting end of the metal strip is fixed on the outer peripheral wall of the inner ring. When the rotating inner ring reaches a first preset value, the graphite strip is loaded so that the graphite strip and the metal strip are wound synchronously. When the number of winding turns reaches a second preset value, the graphite strip is cut off, and then the metal strip is wound alone. Finally, the metal strip is fixed to obtain a low-temperature resistant metal wound gasket, and the low-temperature resistant metal wound gasket is grabbed to a preset placement position, thereby realizing the automated production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket higher.

[0020] Optionally, detecting whether the graphite strip is broken during the winding process;

[0021] When the graphite strip is broken, obtaining length information of the broken portion and position information of the breaking point, wherein the broken portion refers to the portion of the graphite strip from the starting end to the broken portion, and the breaking points include a first breaking point on the broken portion and a second breaking point on the graphite strip opposite to the broken portion;

[0022] Determine whether the length corresponding to the length information is less than a preset lower limit length;

[0023] If so, controlling the inner ring to rotate in the opposite direction according to the position information so that the broken portion is located at the feeding area;

[0024] Blowing off the broken part;

[0025] Executing the graphite strip feeding so that the second breaking point enters the feeding area;

[0026] Controlling the inner ring to rotate so that the graphite strip and the metal strip are wound synchronously;

[0027] If not, the graphite strips are controlled according to a preset docking method.

[0028] By adopting the above technical solution, when a graphite strip breaks during the winding process, the broken portion can be blown off based on the length and position information of the broken portion, if the length corresponding to the length information is less than a preset lower limit, and then the graphite strip and metal strip can be rewound synchronously. If the length corresponding to the length information is not less than the preset lower limit, the graphite strip can be controlled according to a preset docking method, thereby effectively handling the situation of graphite strip breakage and reducing the probability of a decrease in the sealing effect of the low-temperature resistant metal spiral wound gasket.

[0029] Optionally, the step of controlling the graphite strip according to a preset docking method includes:

[0030] Detecting the distance from the first breaking point to the second breaking point to obtain a breaking distance;

[0031] When the breaking distance is greater than a preset distance, controlling the inner ring to rotate in the opposite direction so that the first breaking point is located at the feeding area;

[0032] Obtaining shape information of the breaking point;

[0033] Determining whether the shape corresponding to the shape information is a preset fracture shape;

[0034] If so, controlling the graphite strip to move toward the feeding area so that the second breaking point abuts against the first breaking point;

[0035] Controlling the inner ring to rotate in a forward direction so that the graphite strip, the broken portion and the metal strip are wound synchronously;

[0036] If not, the graphite strip is controlled according to a preset cutting method.

[0037] By adopting the above technical solution, when the length information corresponding to the fractured portion is greater than a preset lower limit and the fracture distance is greater than a preset distance, the shape information of the fracture point is obtained. If the shape information corresponds to the preset fracture shape, the graphite strip is controlled to move so that the second fracture point abuts the first fracture point. Then, by rotating the inner ring, the graphite strip, the fractured portion, and the metal strip are wound synchronously. If the shape information does not correspond to the preset fracture shape, the graphite strip is controlled according to the preset cutting method. This helps to reduce the gap between the first and second fracture points, thereby improving the sealing effect of the low-temperature-resistant metal spiral wound gasket.

[0038] Optionally, the step of controlling the graphite strip according to a preset cutting method includes:

[0039] Acquire a first breaking length of the first breaking point and a second breaking length of the second breaking point according to the shape information;

[0040] Controlling the second breaking point to move in a direction away from the inner ring to a cutting station;

[0041] Removing the second break point according to the second break length to obtain a second resection point;

[0042] Controlling the inner ring to rotate in the opposite direction so that the first breaking point moves toward the second cutting point to the cutting station;

[0043] Removing the first break point according to the first break length to obtain a first resection point;

[0044] Controlling the inner ring to rotate forward so that the first cutting point is located at the feed area;

[0045] Controlling the graphite strip to move toward the feeding area so that the second cutting point abuts against the first cutting point;

[0046] The inner ring is controlled to continue to rotate in the forward direction, so that the graphite strip, the broken part and the metal strip are wound synchronously.

[0047] By adopting the above technical solution, when the shape corresponding to the shape information is not a preset fracture shape, the first fracture length of the first fracture point and the second fracture length of the second fracture point are obtained based on the shape information, and the first fracture point is cut according to the first fracture length and the second fracture point is cut according to the second fracture length. The cut graphite strip, the cut fracture portion, and the metal strip are then synchronously wound. This helps to reduce the gap between the graphite strip and the fracture portion, thereby improving the sealing effect of the low-temperature resistant metal spiral wound gasket.

[0048] Optionally, during the step of controlling the second breaking point to move toward the direction away from the inner ring to the cutting station, detecting whether the graphite strip has a notch or crack within a preset detection length from the second breaking point;

[0049] If yes, mark the area where the notch or crack is located and the side away from the second fracture point to obtain the problem mark point;

[0050] Controlling the problem marking point to move to the cutting station;

[0051] The graphite strip is cut according to the problem marking point to cut off the graphite strip corresponding to the problem marking point to the second breaking point.

[0052] By adopting the above technical solution, when a notch or crack exists in the graphite strip within the preset detection length from the second breaking point, the area where the notch or crack is located is cut away from the second breaking point and marked to obtain the problem marked point. The graphite strip is then cut based on the problem marked point. This helps reduce the probability of the graphite strip breaking due to the presence of notches or cracks.

[0053] Optionally, controlling the lower movable wheel set to vibrate up and down according to a first preset frequency;

[0054] During the rotation of the inner ring, the tension value of the metal belt is continuously monitored;

[0055] When the tension value is less than a preset lower limit, increasing the displacement amplitude of the downward vibration of the lower movable wheel group;

[0056] When the tension value is greater than a preset lower limit value, the displacement amplitude of the upward vibration of the lower movable wheel group is increased.

[0057] By adopting the above technical solution, the stress on the metal belt after winding is reduced by controlling the lower movable wheel assembly to vibrate up and down at a first preset frequency. By continuously monitoring the tension of the metal belt, if the tension is less than a preset lower threshold, the amplitude of the downward vibration of the lower movable wheel assembly can be increased to increase the tension of the metal belt, thereby reducing the possibility of looseness of the metal belt during winding. If the tension is greater than a preset upper threshold, the amplitude of the upward vibration of the lower movable wheel assembly can be increased to reduce the tension of the metal belt, thereby alleviating the stress concentration problem of the metal belt caused by excessive tension.

[0058] Optionally, during the synchronous winding of the graphite strip and the metal belt, the lower movable wheel assembly is controlled to move upward by a first preset distance according to a first preset speed;

[0059] During the upward movement of the lower movable wheel assembly, the lower movable wheel assembly is controlled to vibrate up and down according to a second preset frequency;

[0060] During the reverse rotation of the inner ring, the metal strip is rewound by the feeding device;

[0061] Controlling the lower movable wheel assembly to move downward a second preset distance according to a second preset speed;

[0062] The lower movable wheel set is controlled to vibrate up and down according to a third preset frequency.

[0063] By adopting the above technical solution, on the one hand, during the synchronous winding of the graphite strip and the metal strip, the lower movable wheel assembly is controlled to move upward a first preset distance according to a first preset speed, thereby reducing the tension of the metal strip, thereby achieving a uniform distribution of tension and pressure between the graphite strip and the metal strip during the synchronous winding process. On the other hand, during the reverse rotation of the inner ring, the lower movable wheel assembly is controlled to move downward a second preset distance according to a second preset speed, thereby increasing the tension of the metal strip. This helps to alleviate the problem of reduced tension caused by a reduced winding radius of the metal strip, which in turn reduces the pressure between the metal strip and the graphite strip.

[0064] In a second aspect, the present application provides a low-temperature resistant metal spiral wound gasket manufacturing system, which adopts the following technical solutions:

[0065] A low-temperature resistant metal spiral wound gasket manufacturing system includes an acquisition module for acquiring length information, position information, fracture distance, shape information, and tension value;

[0066] A memory for storing a program for the method of manufacturing the low-temperature resistant metal spiral wound gasket;

[0067] The program in the processor memory can be loaded and executed by the processor to implement the method for manufacturing the low-temperature resistant metal wound gasket.

[0068] By adopting the above technical solution, the inner ring is moved to a preset working position, and the starting end of the metal strip is fixed on the outer peripheral wall of the inner ring. When the rotating inner ring reaches a first preset value, the graphite strip is loaded so that the graphite strip and the metal strip are wound synchronously. When the number of winding turns reaches a second preset value, the graphite strip is cut off, and then the metal strip is wound alone. Finally, the metal strip is fixed to obtain a low-temperature resistant metal wound gasket, and the low-temperature resistant metal wound gasket is grabbed to a preset placement position, thereby realizing the automated production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket higher.

[0069] In a third aspect, the present application provides a smart terminal that adopts the following technical solution:

[0070] An intelligent terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any one of the above methods.

[0071] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the characteristics of facilitating the improvement of the production efficiency of low-temperature resistant metal spiral wound gaskets, and adopts the following technical solutions:

[0072] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any one of the above-mentioned methods for manufacturing a low-temperature resistant metal spiral wound gasket.

[0073] In summary, this application includes at least one of the following beneficial technical effects:

[0074] 1. By moving the inner ring to a preset working position and fixing the starting end of the metal strip on the outer peripheral wall of the inner ring, when the inner ring is rotated to reach a first preset value, the graphite strip is fed so that the graphite strip and the metal strip are wound synchronously. When the number of winding turns reaches a second preset value, the graphite strip is cut, and then the metal strip is wound separately. Finally, the metal strip is fixed to obtain a low-temperature resistant metal spiral wound gasket, and the low-temperature resistant metal spiral wound gasket is grabbed and placed at a preset placement position. This realizes the automated production of the low-temperature resistant metal spiral wound gasket, making the production efficiency of the low-temperature resistant metal spiral wound gasket higher.

[0075] 2. If a graphite strip breaks during winding, the broken portion can be blown off based on the length and position information of the broken portion. If the length corresponding to the length information is less than the preset lower limit, the broken portion can then be rewound synchronously with the graphite strip and metal strip. If the length corresponding to the length information is not less than the preset lower limit, the graphite strip can be controlled according to the preset docking method, thereby effectively handling the graphite strip breakage and reducing the probability of a decrease in the sealing effect of the low-temperature resistant metal spiral wound gasket.

[0076] 3. By controlling the lower movable wheel assembly to vibrate up and down at a first preset frequency, the stress on the metal belt after winding can be reduced. By continuously monitoring the metal belt tension, if the tension is less than a preset lower threshold, the amplitude of the lower movable wheel assembly's downward vibration can be increased to increase the metal belt tension, thereby reducing the possibility of looseness during the winding process. If the tension is greater than a preset upper threshold, the amplitude of the lower movable wheel assembly's upward vibration can be increased to reduce the metal belt tension, thereby alleviating the stress concentration problem caused by excessive tension on the metal belt.

DETAILED DESCRIPTION

[0087] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0088] The present application discloses a device for manufacturing a low-temperature resistant metal spiral wound gasket. Figure 1 The low-temperature resistant metal spiral wound gasket manufacturing device includes a metal strip feeding mechanism 1, a graphite strip feeding mechanism 2, and a winding mechanism 3 for winding the metal strip and the graphite strip.

[0089] The metal strip feeding mechanism 1 includes a first unwinding assembly 11 for unwinding the metal strip, a first conveyor track 12 for conveying the metal strip, a vibrating assembly 13 positioned between the first unwinding assembly 11 and the first conveyor track 12, and a first cutting assembly 14 positioned on the first conveyor track 12. The vibrating assembly 13 includes an upper fixed wheel assembly 131 and a lower movable wheel assembly 132. After exiting the first unwinding assembly 11, the metal strip passes through the upper fixed wheel assembly 131 and the lower movable wheel assembly 132 and enters the first conveyor track 12. The first conveyor track 12 then conveys the metal strip to the winding mechanism 3.

[0090] The graphite strip feeding mechanism 2 includes a second unwinding assembly 21 for placing the graphite strips, a second conveying track 22 for conveying the graphite strips, and a second cutting assembly 23 arranged on the second conveying track 22 .

[0091] The winding mechanism 3 includes a rotating platform 31 for mounting the inner ring and a welding mechanism 32 provided on the lower side of the rotating platform 31 . The rotating platform 31 can drive the inner ring to rotate.

[0092] The present application discloses a method for manufacturing a low-temperature resistant metal spiral wound gasket. Figure 2 The manufacturing method of low temperature resistant metal spiral wound gasket includes:

[0093] Step S201: grab the inner ring by a robot arm and move the inner ring to a preset working position.

[0094] The preset working position is where the inner ring is placed and rotated. The inner ring is grasped by a robot arm and then transferred to a rotating table. The rotating table fixes the inner side wall of the inner ring and can rotate the inner ring by rotating the table.

[0095] Step S202: Fix the starting end of the metal strip to the outer peripheral wall of the inner ring to form a first fixing point.

[0096] For example, the metal strip is conveyed along the first conveyor track. When the starting end of the metal strip is below the inner ring on the rotating table, the metal strip is stopped and the starting end of the metal strip is welded to the outer circumferential wall of the inner ring using a welding mechanism. The starting end is the end where the graphite strip is first wound, and the welding point is the first fixing point.

[0097] Step S203: Control the inner ring to rotate and drive the metal belt to be wound. When the number of rotations of the inner ring reaches a first preset value, control the inner ring to stop rotating.

[0098] The first preset value is a preset constant and can be adjusted according to actual needs. In this embodiment, the first preset value can be set to 3 turns.

[0099] For example, the rotating table rotates, driving the inner ring to rotate as well, thereby causing the metal belt, whose starting end is fixed to the inner ring, to be wound around the inner ring. When the rotating table has rotated three times, i.e., when the number of rotations of the inner ring reaches a first preset value, the rotating table is controlled to pause, thereby controlling the inner ring to pause rotation. At this point, the number of rotations of the metal belt around the inner ring is three.

[0100] Step S204: Execute graphite strip feeding, make the graphite strip pass through the feeding area, and control the rotation of the inner ring to make the graphite strip and the metal strip be wound synchronously.

[0101] The feeding area is the angle area formed between the metal belt delivered from the first conveyor track and the metal belt wound on the inner ring. After entering the angle area, the graphite strip can fit with the metal belt. Then the inner ring is controlled to rotate. Under the action of the friction force of the metal belt, the graphite strip can be driven to follow the metal belt for synchronous winding, so that there is a circle of metal belt between two adjacent circles of graphite strips.

[0102] Optionally, a pressure wheel is provided above the rotating table. When the rotating table drives the inner ring to rotate, the pressure wheel can move downward, so that the metal belt and the graphite strip are less likely to deviate during the winding process.

[0103] Step S205: When the number of rotations of the inner ring reaches a second preset value, the inner ring is controlled to stop rotating and the graphite strip is cut.

[0104] The second preset value is a preset constant related to the number of rotations of the inner ring and can be adjusted according to actual needs. The number of turns of the graphite strip and the metal belt can be adjusted by adjusting the second preset value.

[0105] Exemplarily, when the number of revolutions driven by the turntable to rotate the inner ring reaches a second preset value, the turntable is stopped, thereby controlling the inner ring to stop rotating, and then the graphite strip on the second conveying track is cut by the second cutting assembly.

[0106] Step S206: controlling the inner ring to continue rotating so as to complete the winding of the remaining graphite strips.

[0107] For example, after the graphite strips on the second conveying track are cut, a portion of the graphite strips remains that has not been wound around the outer side of the inner ring. Therefore, the inner ring is controlled to rotate so that this portion of the graphite strips can be wound synchronously with the metal belt.

[0108] Step S207: Control the inner ring to continue rotating to drive the metal belt to be wound separately.

[0109] After the remaining unwound graphite strip is wound, several turns of metal strip need to be wound separately to protect the graphite strip. Therefore, the inner ring needs to be controlled to continue rotating to drive the metal strip for separate winding.

[0110] Step S208: When the number of rotations of the inner ring reaches a third preset value, the inner ring is controlled to stop rotating and the metal strip is cut.

[0111] The third preset value is a preset constant and can be adjusted according to actual needs. In this embodiment, the third preset value can be set to 3 turns.

[0112] For example, after the inner ring rotates three times, the rotating table is controlled to stop rotating, and the metal strip on the first conveying track is cut by the first cutting assembly.

[0113] Step S209: Control the inner ring to continue rotating so that the remaining metal strips are wound.

[0114] For example, after the metal strip on the first conveyor track is cut, a portion of the metal strip remains that has not been wound, and therefore, the inner ring is controlled to rotate so that this portion of the metal strip is wound outside the inner ring.

[0115] Step S210: Fix the two outermost layers of metal strips to form a second fixing point, thereby obtaining a low-temperature resistant metal spiral wound gasket.

[0116] For example, after the metal strip is wound, the welding mechanism located on the lower side of the rotating table can move upward to abut the metal strip, so that the outermost two layers of metal strip are welded and fixed, thereby obtaining a low-temperature resistant metal spiral wound gasket. The welding point is the second fixing point.

[0117] Step S211: grab the low-temperature resistant metal wound gasket to a preset placement position using a robotic arm.

[0118] The preset placement location is an area for storing low-temperature resistant metal spiral wound gaskets. After the low-temperature resistant metal spiral wound gaskets are manufactured, the low-temperature resistant metal spiral wound gaskets are removed from the rotating table by a robot and moved to the preset placement location.

[0119] By adopting the above technical solution, the inner ring is moved to a preset working position, and the starting end of the metal strip is fixed on the outer peripheral wall of the inner ring. When the rotating inner ring reaches a first preset value, the graphite strip is loaded so that the graphite strip and the metal strip are wound synchronously. When the number of winding turns reaches a second preset value, the graphite strip is cut off, and then the metal strip is wound alone. Finally, the metal strip is fixed to obtain a low-temperature resistant metal wound gasket, and the low-temperature resistant metal wound gasket is grabbed to a preset placement position, thereby realizing the automated production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket higher.

[0120] In the following embodiments, during the synchronous winding process of the graphite strip and the metal strip, the graphite strip may break, which reduces the sealing effect of the low-temperature resistant metal spiral wound gasket. To solve this problem, the embodiment of the present application discloses a method for handling graphite strip breakage. Figure 3 , the method comprising:

[0121] Step S301: Detect whether the graphite strip is broken during the winding process.

[0122] Exemplarily, a camera is provided on one side of the rotating table. The camera can obtain a real-time image of the graphite strip when the graphite strip and the metal belt are synchronously wound, and determine whether the graphite strip is broken based on the real-time image.

[0123] Step S302: When a graphite strip is broken, obtain the length information of the broken portion and the position information of the breaking point, wherein the broken portion refers to the portion of the graphite strip from the starting end to the breaking point, and the breaking point includes a first breaking point located on the broken portion and a second breaking point on the graphite strip opposite to the broken portion.

[0124] On the other hand, if the graphite strip does not break, the process of this embodiment ends.

[0125] The broken portion refers to the portion of the graphite strip from the starting end to the break, i.e., the portion that has been wound but cannot be connected to the subsequent graphite strip. The subsequent graphite strip that cannot be connected to the broken portion is defined as the graphite strip strip.

[0126] The length information refers to the length of the broken part. According to the real-time image of the graphite strip, the distance from the broken part to the center of the circle and the central angle of the circle can be obtained, so that the length of the broken part can be calculated to obtain the length information.

[0127] The breaking points include a first breaking point located on a side of the breaking portion away from the starting section and a second breaking point on the graphite strip opposite to the breaking portion.

[0128] The position information indicates the location of the fracture point during the winding process of the graphite strip and the metal strip, which can be obtained through real-time images and can reflect the specific location of the fracture point after the graphite strip breaks.

[0129] Step S303: Determine whether the length corresponding to the length information is less than a preset lower limit length.

[0130] The preset lower limit length is a preset constant, which is related to the length of the broken portion and can be adjusted according to actual needs.

[0131] By comparing the length corresponding to the length information with the preset lower limit length, if the length information is less than the preset lower limit length, step S305 is executed; if the length lower limit is not less than the preset lower limit length, step S308 is executed.

[0132] Step S304: If yes, control the inner ring to rotate in the opposite direction according to the position information so that the broken part is located at the feeding area.

[0133] If so, it means that the length corresponding to the length information is less than the preset lower limit length. Therefore, the inner ring is controlled to rotate in the opposite direction according to the position information so that the broken part is located at the feeding area.

[0134] Exemplarily, when the length corresponding to the length information is less than the preset lower limit length, the inner ring is controlled to rotate in the opposite direction, and the second conveying track works in the opposite direction. On the one hand, the graphite strip is gradually returned from the winding state to the second conveying track, and on the other hand, the broken part can be returned to the feeding area.

[0135] Step S305: Blow off the broken part.

[0136] Exemplarily, a blowing head is provided at the feeding area, and the blowing head sprays gas to blow off the broken parts.

[0137] Step S306: Execute graphite strip loading, so that the second breaking point enters the feeding area.

[0138] Exemplarily, after the broken portion is blown off, the second conveying track operates in the forward direction, so that the graphite strip is conveyed toward the feeding area, and the second breaking point enters the feeding area to abut against the metal strip.

[0139] Step S307: Control the inner ring to rotate so that the graphite strip and the metal strip are wound synchronously.

[0140] For example, after entering the feeding area at the second breaking point, the rotating table is controlled to rotate forward to drive the inner ring to rotate forward, thereby driving the metal belt to be wound. Under the action of the friction force of the metal belt, the graphite strip is wound synchronously with the metal belt.

[0141] Step S308: If not, control the graphite strips according to a preset docking method.

[0142] If not, it means that the length corresponding to the length information is not less than the preset lower limit length, so the graphite strip is controlled according to the preset docking method. For specific steps, please refer to Figure 4 Example.

[0143] By adopting the above technical solution, when a graphite strip breaks during the winding process, the broken portion can be blown off based on the length and position information of the broken portion, if the length corresponding to the length information is less than a preset lower limit, and then the graphite strip and metal strip can be rewound synchronously. If the length corresponding to the length information is not less than the preset lower limit, the graphite strip can be controlled according to a preset docking method, thereby effectively handling the situation of graphite strip breakage and reducing the probability of a decrease in the sealing effect of the low-temperature resistant metal spiral wound gasket.

[0144] Reference Figure 4 The steps of controlling the graphite strip according to the preset docking method include:

[0145] Step S401: Detect the distance from the first breaking point to the second breaking point to obtain the breaking distance.

[0146] According to the real-time image of the graphite strip, the size of the central angle occupied by the first breaking point to the second breaking point can be detected, and the distance from the first breaking point to the second breaking point can be calculated according to the distance from the graphite strip to the center of the circle and the size of the central angle occupied, thereby obtaining the fracture distance.

[0147] Step S402: When the breaking distance is greater than the preset distance, the inner ring is controlled to rotate in the opposite direction so that the first breaking point is located at the feeding area.

[0148] On the other hand, when the fracture distance is not greater than the preset distance, the process of this embodiment is terminated.

[0149] The preset distance is a preset constant, which is related to the distance between the first breaking point and the second breaking point and can be adjusted according to actual needs.

[0150] For example, when the fracture distance is greater than the preset distance, it means that the distance between the fracture part and the graphite strip is large, resulting in poor sealing effect at the gap. Therefore, the inner ring is controlled to rotate in the opposite direction, and the second conveying track is simultaneously conveyed in the opposite direction to retract the graphite strip. When the first fracture point is located at the feed area, the inner ring is stopped from rotating and the graphite strip is stopped from retracting.

[0151] Step S403: Obtaining the shape information of the breakpoint.

[0152] Optionally, a first detection camera is provided above the feeding area.

[0153] The first detection camera can photograph the first breaking point and the second breaking point respectively, and can obtain shape information of the first breaking point and the second breaking point through an edge detection method.

[0154] Step S404: determining whether the shape corresponding to the shape information is a preset fracture shape.

[0155] The preset fracture shape is a preset shape, which is related to the shape of the fracture point.

[0156] For example, the shape in which the fracture surface at the fracture point occupies less than the width of the graphite strip as the overall length is a predetermined fracture shape, and the shape in which the fracture surface at the fracture point occupies not less than the width of the graphite strip as the overall length is a non-predetermined fracture shape. Figure 5 , Figures a, b, c, and d are preset fracture shapes, while Figures e, f, g, and h are non-preset fracture shapes. Referring to Figure b, the left part is the second fracture point, and the right part is the first fracture point. The fracture surface of the first and second fracture points occupies less than the width of the graphite strip, making it easier to connect the first and second fracture points. Referring to Figure f, the left part is the second fracture point, and the right part is the first fracture point. The fracture surface of the first and second fracture points occupies more than the width of the graphite strip, making it more difficult to connect the first and second fracture points. After connection, the connection effect is poor due to the long fracture surface.

[0157] Step S405: If yes, control the graphite strip to move toward the feeding area so that the second breaking point abuts against the first breaking point.

[0158] If so, it means that the shape corresponding to the shape information is a preset fracture shape.

[0159] Exemplarily, when the shape corresponding to the shape information is a preset fracture shape, the graphite strip is transported in the forward direction through the second conveying track to transport it toward the feed area, so that the second fracture point abuts the first fracture point to complete the docking of the first fracture point and the second fracture point.

[0160] Step S406: Control the inner ring to rotate in the forward direction so that the graphite strip, the broken portion and the metal strip are wound synchronously.

[0161] For example, after the first and second break points are aligned, the rotating table is controlled to rotate forward, driving the inner ring to rotate, thereby driving the graphite strip, the broken portion, and the metal strip to be wound synchronously. To prevent the first and second break points from separating when the inner ring first starts to rotate, the second conveyor track conveys the graphite strip in a forward direction when the inner ring first starts to rotate, so that the first and second break points always remain in contact, thereby preventing the first and second break points from separating.

[0162] Step S407: If not, control the graphite strip according to a preset cutting method.

[0163] If not, it means that the shape corresponding to the shape information is not the preset fracture shape, so the graphite strip is controlled according to the preset cutting method. The specific steps can be referred to Figure 6 Example.

[0164] By adopting the above technical solution, when the length information corresponding to the fractured portion is greater than a preset lower limit and the fracture distance is greater than a preset distance, the shape information of the fracture point is obtained. If the shape information corresponds to the preset fracture shape, the graphite strip is controlled to move so that the second fracture point abuts the first fracture point. Then, by rotating the inner ring, the graphite strip, the fractured portion, and the metal strip are wound synchronously. If the shape information does not correspond to the preset fracture shape, the graphite strip is controlled according to the preset cutting method. This helps to reduce the gap between the first and second fracture points, thereby improving the sealing effect of the low-temperature-resistant metal spiral wound gasket.

[0165] Reference Figure 6 The steps of controlling the graphite strip according to the preset cutting method include:

[0166] Step S501: obtaining a first break length of a first break point and a second break length of a second break point according to shape information.

[0167] The first fracture length refers to the length of the graphite strip occupied by the fracture surface of the first fracture point in the longitudinal direction of the graphite strip.

[0168] The second fracture length refers to the length of the graphite strip occupied by the fracture surface of the second fracture point in the longitudinal direction of the graphite strip.

[0169] For example, the fracture surface of the first fracture point is projected onto the length direction of the graphite strip according to the shape information to obtain the first fracture length. The fracture surface of the second fracture point is projected onto the length direction of the graphite strip according to the shape information to obtain the second fracture length.

[0170] Step S502: Control the second breaking point to move toward the direction away from the inner circle to the cutting station.

[0171] The cutting station is a station for cutting the graphite strip. In the present embodiment, the cutting station is the area where the second cutting assembly is located.

[0172] Exemplarily, the second conveying track conveys the graphite strip in the reverse direction so that the second breaking point is located at the lower side of the second cutting assembly.

[0173] Step S503: cutting off the second breaking point according to the second breaking length to obtain a second cutting off point.

[0174] For example, when the second breaking point is located below the second cutting assembly, the second cutting assembly cuts the second breaking point according to the second breaking length to obtain the second cutting point. The second cutting assembly is provided with a nozzle that blows the cut graphite strips off the second conveyor track.

[0175] Step S504: Control the inner ring to rotate in the opposite direction so that the first breaking point moves toward the second breaking point to the cutting station.

[0176] Exemplarily, the rotary table rotates in the opposite direction, so that the broken part arranged on the outer side of the inner ring retreats toward the second conveying track, so that the first breaking point moves toward the second breaking point to the cutting station, that is, below the second cutting assembly.

[0177] Step S505: cutting off the first break point according to the first break length to obtain a first cut point.

[0178] For example, when the first breaking point is located below the first cutting assembly, the second cutting assembly cuts the first breaking point according to the first breaking length to obtain the first cutting point. The cut graphite strip is then blown off the second conveying track by the nozzle.

[0179] Step S506: Control the inner ring to rotate forward so that the first cutting point is located at the feeding area.

[0180] After the first breaking point and the second breaking point are cut off, the inner ring is rotated in the forward direction by controlling the rotary table to rotate forward, thereby driving the broken part to be wound. When the first cutting point is located at the feeding area, the inner ring stops rotating.

[0181] Step S507: controlling the graphite strip to move toward the feeding area so that the second cutting point abuts against the first cutting point.

[0182] When the first cutting point is located in the feeding area, the second conveying track is controlled to convey in a forward direction so that the second cutting point abuts against the first cutting point.

[0183] Step S508: Control the inner ring to continue to rotate in the forward direction, so that the graphite strip, the broken part and the metal strip are wound synchronously.

[0184] After the second cut-off point abuts the first cut-off point, the rotary table is controlled to rotate forward, thereby controlling the inner ring to continue to rotate forward. Under the action of the friction force of the metal strip, the graphite strip is wound synchronously with the broken portion and the metal strip. In order to prevent the first and second cut-off points from separating when the inner ring first starts to rotate, the second conveyor track conveys the graphite strip in the forward direction when the inner ring first starts to rotate, so that the first and second cut-off points always abut each other, thereby preventing the first and second cut-off points from separating.

[0185] By adopting the above technical solution, when the shape corresponding to the shape information is not a preset fracture shape, the first fracture length of the first fracture point and the second fracture length of the second fracture point are obtained based on the shape information, and the first fracture point is cut according to the first fracture length and the second fracture point is cut according to the second fracture length. The cut graphite strip, the cut fracture portion, and the metal strip are then synchronously wound. This helps to reduce the gap between the graphite strip and the fracture portion, thereby improving the sealing effect of the low-temperature resistant metal spiral wound gasket.

[0186] In the following embodiments, the reason for the fracture of the graphite strip may be due to excessive stretching, and excessive stretching of the graphite strip may cause gaps or cracks in other areas. The presence of gaps or cracks increases the probability of the graphite strip fracture. To solve this problem, the embodiment of the present application discloses a method for preventing the fracture of the graphite strip. Figure 7 , the method comprising:

[0187] Step S601: During the step of controlling the second breaking point to move toward the direction away from the inner ring to the cutting station, detect whether there is a notch or crack in the graphite strip within a preset detection length from the second breaking point.

[0188] The preset detection length is a preset length and can be adjusted according to actual needs.

[0189] Exemplarily, a second detection camera is provided at the second cutting assembly. During the execution of step S502, the second detection camera can continuously shoot the graphite strip in real time, and analyze the real-time shot image to determine whether there is a notch or crack in the graphite strip passing through the second detection camera, and the distance between the notch or crack and the second breaking point is within the preset detection length.

[0190] Step S602: If yes, mark the area where the notch or crack is located and the side away from the second breaking point to obtain a problem marking point.

[0191] On the other hand, if not, it means that no gap or crack is detected in the graphite strip within the preset detection length from the second breaking point, and thus the process of this embodiment ends.

[0192] If yes, it means that a gap or crack is detected in the graphite strip within the preset detection length from the second breaking point. Therefore, the area where the gap or crack is located is cut away from the second breaking point and marked to obtain the problem marked point.

[0193] Step S603: Control the problem marking point to move to the cutting station.

[0194] Exemplarily, when the second conveying track is conveying the graphite strip in the reverse direction, when the problem marking point is located below the second cutting assembly, the conveying of the graphite strip by the second conveying track is suspended.

[0195] Step S604: performing a cutting operation on the graphite strip according to the problem marking point, so as to cut off the graphite strip corresponding to the problem marking point to the second breaking point.

[0196] Exemplarily, the second cutting component cuts the graphite strip according to the problem marking point, so as to cut off the graphite strip corresponding to the problem marking point to the second breaking point.

[0197] By adopting the above technical solution, when a notch or crack exists in the graphite strip within the preset detection length from the second breaking point, the area where the notch or crack is located is cut away from the second breaking point and marked to obtain the problem marked point. The graphite strip is then cut based on the problem marked point. This helps reduce the probability of the graphite strip breaking due to the presence of notches or cracks.

[0198] In the following embodiments, the metal strip will generate internal stress due to curling deformation during the winding process, and as the winding radius gradually increases, the linear speed of the metal strip increases accordingly, which may easily lead to stress concentration problems such as loose metal strip, loose winding or excessive tension. In order to solve this problem, the embodiment of the present application provides a dynamic tension adjustment method. Figure 8 , the method comprising:

[0199] Step S701: Control the lower movable wheel assembly to vibrate up and down according to a first preset frequency.

[0200] Reference Figure 1 The upper fixed wheel assembly 131 includes a first fixed wheel 1311 and a second fixed wheel 1312 arranged horizontally parallel to the first fixed wheel 1311. The lower movable wheel assembly 132 includes a first movable wheel 1321 and a second movable wheel 1322 arranged horizontally parallel to the first movable wheel 1321. After the metal strip is discharged from the first unwinding assembly 11, it passes through the first fixed wheel 1311, the first movable wheel 1321, the second fixed wheel 1312, and the second movable wheel 1322 in sequence before entering the first conveyor track 12. The lower movable wheel assembly 132 is capable of vertically oscillating up and down.

[0201] The first preset frequency is a preset frequency, which is related to the time it takes for the lower movable wheel set to vibrate once, and can be adjusted according to actual needs.

[0202] By controlling the lower movable wheel group to vibrate up and down according to the first frequency, the metal belt wrapped around the upper fixed wheel group and the lower movable wheel group can be driven to vibrate accordingly. Through vibration, the stress inside the material can be redistributed in the form of tiny plastic deformation, so that the local stress concentration area can be relieved, thereby reducing the residual stress of the metal belt.

[0203] Step S702: During the rotation of the inner ring, the tension value of the metal belt is continuously monitored.

[0204] The tension value indicates the pulling force on the metal strip during winding.

[0205] Exemplarily, the upper fixed wheel set and the lower movable wheel set are provided with force sensors. During the rotation of the inner ring, since the metal belt passes through the upper fixed wheel set and the lower movable wheel set in sequence, the tension value on the metal belt can be obtained through the force sensor.

[0206] Step S703: when the tension value is less than the preset lower limit, increasing the displacement amplitude of the downward vibration of the lower movable wheel group.

[0207] The preset lower limit value is a preset constant, which is related to the tension on the metal belt and can be adjusted according to actual needs.

[0208] If the tension value is less than the preset lower limit, it means that the tension on the metal belt is too low, and the metal belt is prone to loose winding during winding, which will reduce the sealing effect of the low-temperature resistant metal spiral wound gasket. Therefore, the tension on the metal belt needs to be adjusted. When the lower movable wheel group vibrates up and down, the downward displacement amplitude of the lower movable wheel group is increased to increase the tension on the metal belt.

[0209] For example, the amplitude of the lower movable wheel assembly when vibrating up and down is (-A, A), where upward vibration is positive and downward vibration is negative. The amplitude after increasing the displacement amplitude of the lower movable wheel assembly's downward vibration is (-Aa, A), where a is the increased vibration amplitude.

[0210] Step S704: when the tension value is greater than the preset lower limit, increasing the displacement amplitude of the upward vibration of the lower movable wheel group.

[0211] The preset lower limit value is a preset constant, which is related to the tension on the metal belt and can be adjusted according to actual needs.

[0212] If the tension value is greater than the preset lower limit, it indicates that the tension on the metal belt is too high. This excessive tension can lead to stress concentration during winding, so the tension on the metal belt needs to be adjusted. When the lower movable pulley vibrates up and down, the upward displacement of the lower movable pulley is increased to reduce the tension on the metal belt.

[0213] For example, the amplitude of the lower movable wheel assembly when vibrating up and down is (-A, A), where upward vibration is positive and downward vibration is negative. The amplitude after increasing the displacement amplitude of the lower movable wheel assembly's upward vibration is (-A, A+b), where b is the increased vibration amplitude.

[0214] By adopting the above technical solution, the stress on the metal belt after winding is reduced by controlling the lower movable wheel assembly to vibrate up and down at a first preset frequency. By continuously monitoring the tension of the metal belt, if the tension is less than a preset lower threshold, the amplitude of the downward vibration of the lower movable wheel assembly can be increased to increase the tension of the metal belt, thereby reducing the possibility of looseness of the metal belt during winding. If the tension is greater than a preset upper threshold, the amplitude of the upward vibration of the lower movable wheel assembly can be increased to reduce the tension of the metal belt, thereby alleviating the stress concentration problem of the metal belt caused by excessive tension.

[0215] In the following embodiments, the present application provides a dynamic adjustment method, referring to Figure 9 , the method comprising:

[0216] Step S801: During the synchronous winding of the graphite strip and the metal belt, the movable wheel assembly is controlled to move upward by a first preset distance according to a first preset speed.

[0217] The second preset speed is negatively correlated with the rotation time of the inner ring and can be adjusted according to actual needs.

[0218] The first preset distance is a preset constant, which represents the maximum distance that the lower movable wheel group moves upward, and can be adjusted according to actual needs.

[0219] During the synchronous winding of the graphite strip and the metal strip, as the winding radius gradually increases, the tension of the metal strip gradually increases, which in turn increases the pressure on the graphite strip, causing deformation, damage to the graphite strip, or unstable winding. Therefore, by controlling the lower movable wheel assembly to move upward at a first preset speed and a first preset distance, the tension and pressure of the graphite strip and the metal strip during the synchronous winding process are ensured to be evenly distributed.

[0220] Step S802: During the upward movement of the lower movable wheel assembly, the lower movable wheel assembly is controlled to vibrate up and down according to a second preset frequency.

[0221] The second preset frequency is a preset constant and can be adjusted according to actual needs. In this embodiment, the second preset frequency can be the same as the first preset frequency, or the second preset frequency can be different from the first preset frequency.

[0222] By controlling the lower movable wheel assembly to vibrate up and down at a second preset frequency, on the one hand, it is possible to ensure that the metal strip maintains uniform tension during the winding process, thereby avoiding uneven winding or uneven force on the graphite strip due to tension fluctuations. On the other hand, it is possible to reduce the stress on the metal strip.

[0223] Step S803: While the inner ring is rotating in the reverse direction, the metal strip is rewound by the loading device.

[0224] The rewinding operation is an operation of rewinding the metal strip through the first unwinding assembly.

[0225] During the reverse rotation of the inner ring, if the metal strip is not rewound, it may become loose, resulting in uneven winding during subsequent rewinding. Therefore, the metal strip is rewound by a loading device.

[0226] Exemplarily, when the rotary table rotates in the reverse direction, the first unwinding assembly drives the metal strip to reel in, so that the tension on the metal strip is uniform.

[0227] Step S804: controlling the lower movable wheel assembly to move downward a second preset distance according to a second preset speed.

[0228] The second preset speed is negatively correlated with the rotation time of the inner ring and can be adjusted according to actual needs.

[0229] The second preset distance is a preset constant, which represents the maximum distance that the lower movable wheel group moves downward, and can be adjusted according to actual needs.

[0230] As the inner ring rotates in the opposite direction, the metal strip decreases along with the winding radius, reducing the tension on the metal strip and the pressure on the graphite strip. This reduces the tightness between the metal strip and the graphite strip during subsequent winding. Therefore, by controlling the lower movable wheel assembly to move upward by a second preset distance at a second preset speed, the tension and pressure distribution of the graphite strip and metal strip during the subsequent synchronous winding process is ensured to be uniform.

[0231] Step S805: controlling the lower movable wheel assembly to vibrate up and down according to a third preset frequency.

[0232] The third preset frequency is a preset constant and can be adjusted according to actual needs. In this embodiment, the third preset frequency can be the same as the first preset frequency, or the third preset frequency can be different from the first preset frequency.

[0233] By controlling the lower movable wheel group to vibrate up and down according to the third preset frequency, the stress on the metal belt can be effectively reduced, and the metal belt can be prevented from being overstretched or deformed.

[0234] By adopting the above technical solution, on the one hand, during the synchronous winding of the graphite strip and the metal strip, the lower movable wheel assembly is controlled to move upward a first preset distance according to a first preset speed, thereby reducing the tension of the metal strip, thereby achieving a uniform distribution of tension and pressure between the graphite strip and the metal strip during the synchronous winding process. On the other hand, during the reverse rotation of the inner ring, the lower movable wheel assembly is controlled to move downward a second preset distance according to a second preset speed, thereby increasing the tension of the metal strip. This helps to alleviate the problem of reduced tension caused by a reduced winding radius of the metal strip, which in turn reduces the pressure between the metal strip and the graphite strip.

[0235] Based on the same inventive concept, the present embodiment provides a low-temperature resistant metal spiral wound gasket manufacturing system, comprising:

[0236] An acquisition module is used to obtain length information, position information, fracture distance, shape information, and tension value;

[0238] The program in the processor memory can be loaded and executed by the processor to realize the above-mentioned method for manufacturing the low-temperature resistant metal wound gasket.

[0239] By adopting the above technical solution, the inner ring is moved to a preset working position, and the starting end of the metal strip is fixed on the outer peripheral wall of the inner ring. When the rotating inner ring reaches a first preset value, the graphite strip is loaded so that the graphite strip and the metal strip are wound synchronously. When the number of winding turns reaches a second preset value, the graphite strip is cut off, and then the metal strip is wound alone. Finally, the metal strip is fixed to obtain a low-temperature resistant metal wound gasket, and the low-temperature resistant metal wound gasket is grabbed to a preset placement position, thereby realizing the automated production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket higher.
