Description

Technical Field

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

[0002] Low-temperature-resistant metal spiral wound gaskets are mainly used for fluid sealing and are widely used in the fields of petroleum, chemical industry, shipbuilding, aerospace and nuclear industry. In the field of marine engineering, low-temperature-resistant metal spiral wound gaskets are widely used in sealing parts in harsh environments such as submarine pipelines, offshore platforms and ship power systems due to their excellent corrosion resistance, creep resistance and low-temperature resistance. They can effectively resist extreme working conditions such as seawater corrosion, high-pressure shock and temperature fluctuations, and provide key guarantees for the safe operation of marine equipment. Among them, low-temperature-resistant metal spiral wound gaskets are usually made of low-temperature-resistant metal materials, have excellent low-temperature resistance, and can maintain good sealing and structural stability in low-temperature environments.

[0003] The low temperature resistant metal wound gasket includes an inner ring, a metal belt wound around the outer periphery of the inner ring, and a graphite strip. In the related art, the inner ring is usually fixed on a rotating table manually, and then the starting end of the metal belt is welded to the inner ring by manual welding. After the rotating table is started to rotate so that the metal belt is wound several times, the graphite strip is inserted into the angle between the metal belt and the metal belt wound on the inner ring, so that the graphite strip and the metal belt are wound synchronously. After the graphite strip is wound to the specified length, the graphite strip is cut off and the metal belt is wound several times separately, and then the metal belt is welded and fixed.

[0004] With regard to the above-mentioned related technologies, the efficiency of manually manufacturing 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 wound gaskets, the present application provides a method, system, terminal and storage medium for producing low-temperature resistant metal 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: A method for manufacturing a low-temperature resistant metal spiral wound gasket, comprising: Grab the inner ring by a robot and move the inner ring to a preset working position; Fixing the starting end of the metal strip to the outer peripheral wall of the inner ring to form a first fixing point; Controlling the inner ring to rotate and drive the metal belt to be wound, and when the number of rotations of the inner ring reaches a first preset value, controlling the inner ring to stop rotating; Perform the feeding of the graphite strip, so that the graphite strip passes through the feeding area, and control the rotation of the inner ring to wind the graphite strip and the metal strip synchronously; When the number of rotation circles of the inner ring reaches the second preset value, control the inner ring to pause rotation and cut off the graphite strip; Control the inner ring to continue rotating to complete the winding of the remaining graphite strip; Control the inner ring to continue rotating to drive the metal strip to wind separately; When the number of rotation circles of the inner ring reaches the third preset value, control the inner ring to pause rotation and cut off the metal strip; Control the inner ring to continue rotating to complete the winding of the remaining metal strip; Fix the outermost two layers of the metal strip to form a second fixing point to obtain a low-temperature resistant metal wound gasket; Use a manipulator to grab the low-temperature resistant metal wound gasket to a preset placement position.

[0007] By adopting the above technical solution, 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 rotates to the first preset value, by performing the feeding of the graphite strip, the graphite strip and the metal strip are wound synchronously. And when the number of winding circles reaches the second preset value, the graphite strip is cut off. Then the metal strip is wound separately. 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, realizing the automatic production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket relatively high.

[0008] Optionally, detect whether the graphite strip breaks during the winding process; In the case where the graphite strip breaks, obtain the length information of the broken part and the position information of the break point. Wherein, the broken part refers to the part of the graphite strip from the starting end to the break point, and the break point includes the first break point located on the broken part and the second break point on the graphite strip tape opposite to the broken part; Judge whether the length corresponding to the length information is less than a preset lower limit length; If so, control the inner ring to rotate reversely according to the position information so that the broken part is located at the feeding area; Blow off the broken part; Perform the feeding of the graphite strip tape so that the second break point enters the feeding area; Control the inner ring to rotate to wind the graphite strip tape and the metal strip synchronously; If not, control the graphite strip according to a preset docking method.

[0009] By adopting the above technical solution, when the graphite strip breaks during the winding process, it is possible to blow off the broken part according to the length information and position information of the broken part. After the length corresponding to the length information is less than the preset lower limit length, the graphite strip material tape and the metal tape are rewound synchronously. When the length corresponding to the length information is not less than the preset lower limit length, the graphite strip can be controlled according to the preset docking method, so that the situation of the graphite strip breaking can be effectively handled, and the probability of the sealing effect of the low-temperature-resistant metal wound gasket decreasing can be reduced.

[0010] Optionally, the step of controlling the graphite strip according to the preset docking method includes: Detect the distance between the first break point and the second break point to obtain the break distance; When the break distance is greater than the preset distance, control the inner ring to rotate in the reverse direction so that the first break point is located at the feeding area; Obtain the shape information of the break point; Judge whether the shape corresponding to the shape information is the preset break shape; If so, control the graphite strip material tape to move towards the feeding area so that the second break point abuts against the first break point; Control the inner ring to rotate in the forward direction so that the graphite strip material tape, the broken part and the metal tape are wound synchronously; If not, control the graphite strip according to the preset cutting method.

[0011] By adopting the above technical solution, when the length corresponding to the length information of the broken part is greater than the preset lower limit length and the break distance is greater than the preset distance, the shape information of the break point is obtained. When the shape corresponding to the shape information is the preset break shape, by controlling the movement of the graphite strip material tape, the second break point abuts against the first break point, and then by rotating the inner ring, the graphite strip material tape, the broken part and the metal tape are wound synchronously. When the shape corresponding to the shape information is not the preset break shape, the graphite strip is controlled according to the preset cutting method. This helps to reduce the gap between the first break point and the second break point and improve the sealing effect of the low-temperature-resistant metal wound gasket.

[0012] Optionally, the step of controlling the graphite strip according to the preset cutting method includes: Obtain the first break length of the first break point and the second break length of the second break point according to the shape information; Control the second break point to move away from the inner ring to the cutting station; Cut the second break point according to the second break length to obtain the second cut point; Control the reverse rotation of the inner ring to move the first breaking point towards the second cutting point to the cutting station; Cut the first breaking point according to the first breaking length to obtain a first cutting point; Control the forward rotation of the inner ring to make the first cutting point located at the feeding area; Control the graphite strip to move towards the feeding area so that the second cutting point abuts against the first cutting point; Control the inner ring to continue to rotate forward so that the graphite strip, the broken part and the metal strip are wound synchronously.

[0013] By adopting the above technical solution, when the shape corresponding to the shape information is a non-preset breaking shape, the first breaking length of the first breaking point and the second breaking length of the second breaking point are obtained according to the shape information, the first breaking point is cut according to the first breaking length, the second breaking point is cut according to the second breaking length, and then the cut graphite strip, the cut broken part and the metal strip are wound synchronously. This helps to reduce the gap between the graphite strip and the broken part and improve the sealing effect of the low-temperature resistant metal winding gasket.

[0014] Optionally, during the process of performing the step of controlling the second breaking point to move towards 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; If so, mark the area where the notch or crack is located and the side far from the second breaking point to obtain a problem marking point; Control the problem marking point to move to the cutting station; Perform a cutting operation on the graphite strip according to the problem marking point to cut the graphite strip corresponding to the problem marking point to the second breaking point.

[0015] By adopting the above technical solution, when there is a notch or crack in the graphite strip within a preset detection length from the second breaking point, mark the area where the notch or crack is located and the side far from the second breaking point to obtain a problem marking point, and cut the graphite strip according to the problem marking point. This helps to reduce the probability of the graphite strip breaking due to the existence of the notch or crack.

[0016] Optionally, control the lower movable wheel set to vibrate up and down at a first preset frequency; During the rotation of the inner ring, continuously monitor the tension value of the metal strip; When the tension value is less than the preset lower limit value, increase the displacement amplitude of the downward vibration of the lower movable wheel set; When the tension value is greater than a preset lower limit value, increase the displacement amplitude of the upward vibration of the lower movable wheel set.

[0017] By adopting the above technical solution, by controlling the lower movable wheel set to vibrate up and down at a first preset frequency, the stress of the metal strip after output can be reduced. By continuously monitoring the tension value of the metal strip, when the tension value is less than the preset lower limit threshold, the tension value of the metal strip can be increased by increasing the amplitude of the downward vibration of the lower movable wheel set, reducing the situation that the metal strip is not tight during the winding process. When the tension value is greater than the preset upper limit threshold, the amplitude of the upward vibration of the lower movable wheel set can be increased to reduce the tension value of the metal strip, and the problem of stress concentration of the metal strip caused by excessive tension can be improved.

[0018] Optionally, during the synchronous winding process of the graphite strip and the metal strip, control the lower movable wheel set to move upward a first preset distance according to a first preset speed; During the upward movement of the lower movable wheel set, control the lower movable wheel set to vibrate up and down at a second preset frequency; During the reverse rotation of the inner ring, perform a rewinding operation on the metal strip through the feeding device; Control the lower movable wheel set to move downward a second preset distance according to a second preset speed; Control the lower movable wheel set to vibrate up and down at a third preset frequency.

[0019] By adopting the above technical solution, on the one hand, during the synchronous winding process of the graphite strip and the metal strip, by controlling the lower movable wheel set to move upward a first preset distance according to a first preset speed, the tension of the metal strip can be reduced, so that the tension and pressure distribution during the synchronous winding process of the graphite strip and the metal strip are uniform. On the other hand, during the reverse process of the inner ring, by controlling the lower movable wheel set to move downward a second preset distance according to a second preset speed, the tension of the metal strip is increased, which helps to improve the problem that the tension is reduced due to the reduction of the winding radius of the metal strip, and further leads to the reduction of the pressure between the metal strip and the graphite strip.

[0020] In a second aspect, the present application provides a low-temperature resistant metal wound gasket manufacturing system, adopting the following technical solution: A low-temperature resistant metal wound gasket manufacturing system, including an acquisition module for acquiring length information, position information, fracture distance, shape information, and tension value; A memory for storing the program of the low-temperature resistant metal wound gasket manufacturing method; A processor, and the program in the memory can be loaded and executed by the processor to implement the low-temperature resistant metal wound gasket manufacturing method.

[0021] By adopting the above technical solution, the inner ring is transferred 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 rotation of the inner ring reaches the 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 the 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 grasped and placed at a preset placement position, realizing the automatic production of the low-temperature resistant metal wound gasket and making the production efficiency of the low-temperature resistant metal wound gasket relatively high.

[0022] In a third aspect, the present application provides an intelligent terminal, adopting the following technical solution: An intelligent terminal includes a memory and a processor, and a computer program capable of being loaded and executed by the processor for any of the above methods is stored on the memory.

[0023] In a fourth aspect, the present application provides a computer storage medium, which can store corresponding programs and has the characteristic of facilitating the improvement of the production efficiency of low-temperature resistant metal wound gaskets. The following technical solution is adopted: A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor for any of the above methods for manufacturing low-temperature resistant metal wound gaskets.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By transferring 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 rotation of the inner ring reaches the 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 the 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 grasped and placed at a preset placement position, realizing the automatic production of the low-temperature resistant metal wound gasket and making the production efficiency of the low-temperature resistant metal wound gasket relatively high; 2. When the graphite strip breaks during the winding process, according to the length information and position information of the broken part, when the length corresponding to the length information is less than the preset lower limit length, the broken part is blown off, and then the graphite strip material tape and the metal strip are wound synchronously again. When the length corresponding to the length information is not less than the preset lower limit length, the graphite strip can be controlled according to the preset docking method, so that the situation of the graphite strip breaking can be effectively handled, and the probability of the sealing effect of the low-temperature resistant metal wound gasket decreasing can be reduced; 3. By controlling the lower movable wheel set to vibrate up and down at the first preset frequency, the stress of the metal strip after output can be reduced. By continuously monitoring the tension value of the metal strip, when the tension value is less than the preset lower threshold, the amplitude of the downward vibration of the lower movable wheel set can be increased to increase the tension value of the metal strip, reducing the situation of the metal strip being loose during the winding process. When the tension value is greater than the preset upper threshold, the amplitude of the upward vibration of the lower movable wheel set can be increased to reduce the tension value of the metal strip, and the stress concentration problem of the metal strip caused by excessive tension can be improved.

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further details the present application in conjunction with the Figures 1-9 accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] An embodiment of the present application discloses a device for manufacturing a low-temperature resistant metal wound gasket. Refer to Figure 1 , the device for manufacturing a low-temperature resistant metal wound gasket includes a metal strip loading mechanism 1, a graphite strip loading mechanism 2, and a winding mechanism 3 for winding the metal strip and the graphite strip.

[0037] The metal strip loading mechanism 1 includes a first unwinding assembly 11 for unwinding the metal strip, a first conveying track 12 for conveying the metal strip, a vibration assembly 13 disposed between the first unwinding assembly 11 and the first conveying track 12, and a first cutting assembly 14 disposed at the first conveying track 12. The vibration assembly 13 includes an upper fixed wheel set 131 and a lower movable wheel set 132. After the metal strip is output from the first unwinding assembly 11, it enters the first conveying track 12 through the upper fixed wheel set 131 and the lower movable wheel set 132, and the first conveying track 12 then conveys the metal strip to the winding mechanism 3.

[0038] The graphite strip loading mechanism 2 includes a second unwinding assembly 21 for placing the graphite strip, a second conveying track 22 for conveying the graphite strip, and a second cutting assembly 23 disposed on the second conveying track 22.

[0039] The winding mechanism 3 includes a rotary table 31 for installing the inner ring and a welding mechanism 32 disposed on the lower side of the rotary table 31, and the rotary table 31 can drive the inner ring to rotate.

[0040] An embodiment of the present application discloses a method for manufacturing a low-temperature resistant metal wound gasket. Refer to Figure 2 , the method for manufacturing a low-temperature resistant metal wound gasket includes: Step S201: Grasp the inner ring by a manipulator and transfer the inner ring to a preset working position.

[0041] The preset working position is the position where the inner ring is placed and rotated. Among them, the inner ring is grasped by the manipulator, and then the inner ring is moved to the rotating table. The rotating table fixes the inner side wall of the inner ring, and the rotating table can drive the inner ring to rotate by rotation.

[0042] Step S202: Fix the starting end of the metal strip on the outer peripheral wall of the inner ring to form a first fixing point.

[0043] Exemplarily, the metal strip is conveyed along the first conveying track. When the starting end of the metal strip is located below the inner ring on the rotating table, the conveyance of the metal strip is paused, and the starting end of the metal strip is welded to the outer peripheral wall of the inner ring through the welding mechanism. Among them, the starting end is the end where the graphite strip starts to be wound first, and the welding point is the first fixing point.

[0044] Step S203: Control the rotation of the inner ring and drive the metal strip to be wound. When the number of rotation circles of the inner ring reaches the first preset value, control the inner ring to pause rotating.

[0045] 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 circles.

[0046] Exemplarily, the rotating table rotates, driving the inner ring to rotate, thereby driving the metal strip with the starting end fixed on the inner ring to be wound along with the inner ring. When the number of rotation circles of the rotating table reaches 3 circles, that is, when the number of rotation circles of the inner ring reaches the first preset value, control the rotating table to pause rotating to control the inner ring to pause rotating. At this time, the number of winding circles of the metal strip on the inner ring is 3 circles.

[0047] Step S204: Perform the feeding of the graphite strip, make the graphite strip pass through the feeding area, and control the rotation of the inner ring so that the graphite strip and the metal strip are wound synchronously.

[0048] The feeding area is the included angle area formed between the metal strip conveyed from the first conveying track and the metal strip already wound on the inner ring. After the graphite strip enters this included angle area, it can fit with the metal strip. Then, control the inner ring to rotate. Under the action of the friction force of the metal strip, it can drive the graphite strip to be wound synchronously with the metal strip, so that there is one circle of metal strip separating between adjacent two circles of graphite strips.

[0049] Optionally, a pressing wheel is arranged above the rotating table. When the rotating table drives the inner ring to rotate, the pressing wheel can move downward, so that the metal strip and the graphite strip are not prone to deviation during the winding process.

[0050] Step S205: When the number of rotation circles of the inner ring reaches the second preset value, control the inner ring to pause rotating and cut off the graphite strip.

[0051] The second preset value is a preset constant, which is related to the number of rotation circles of the inner ring and can be adjusted according to actual requirements. By adjusting the second preset value, the number of circles of synchronous winding of the graphite strip and the metal strip can be adjusted.

[0052] Exemplarily, when the number of rotation circles of the inner ring driven by the rotating table reaches the second preset value, the rotation of the rotating table is paused, so as to control the inner ring to pause rotating. Then, through the second cutting component, the graphite strip located on the second conveying track is cut.

[0053] Step S206: Control the inner ring to continue rotating so that the remaining graphite strips are completely wound.

[0054] Exemplarily, after the graphite strip located on the second conveying track is cut, there is still a part of the graphite strip that has not been wound on the outer side of the inner ring. Therefore, control the inner ring to rotate so that this part of the graphite strip can be wound synchronously with the metal strip.

[0055] Step S207: Control the inner ring to continue rotating to drive the metal strip to be wound separately.

[0056] When the winding of the remaining unwound part of the graphite strip is completed, several circles of the metal strip need to be wound separately to protect the graphite strip. Therefore, it is also necessary to control the inner ring to continue rotating to drive the metal strip to be wound separately.

[0057] Step S208: When the number of rotation circles of the inner ring reaches the third preset value, control the inner ring to pause rotating and cut the metal strip.

[0058] The third preset value is a preset constant and can be adjusted according to actual requirements. In this embodiment, the third preset value can be set to 3 circles.

[0059] Exemplarily, after the number of rotation circles of the inner ring reaches 3 circles, control the rotating table to pause rotating, and cut the metal strip located on the first conveying track through the first cutting component.

[0060] Step S209: Control the inner ring to continue rotating so that the remaining metal strip is completely wound.

[0061] Exemplarily, after the metal strip located on the first conveying track is cut, there is still a part of the metal strip that has not been wound. Therefore, control the inner ring to rotate so that this part of the metal strip is wound on the outer side of the inner ring.

[0062] Step S210: Fix the outermost two layers of the metal strip to form a second fixing point, and obtain the low-temperature-resistant metal winding gasket.

[0063] Exemplarily, after the metal strip is wound, the welding mechanism located below the rotating table can move upward to abut against the metal strip, so that the outermost two layers of the metal strip are welded and fixed, thereby obtaining a low-temperature resistant metal wound gasket. Among them, the welding point is the second fixed point.

[0064] Step S211: Use a manipulator to grab the low-temperature resistant metal wound gasket to a preset placement position.

[0065] The preset placement position is an area for storing the low-temperature resistant metal wound gasket. After the production of the low-temperature resistant metal wound gasket is completed, the low-temperature resistant metal wound gasket is removed from the rotating table by a manipulator and transferred to the preset placement position.

[0066] By adopting the above technical solution, by moving the inner ring to the 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 rotates to the first preset value, by performing the feeding of the graphite strip, the graphite strip and the metal strip are wound synchronously, and when the number of winding turns reaches the second preset value, the graphite strip is cut off, and then the metal strip is wound alone, and 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 the preset placement position, realizing the automatic production of the low-temperature resistant metal wound gasket, and making the production efficiency of the low-temperature resistant metal wound gasket relatively high.

[0067] In the following embodiments, during the synchronous winding process of the graphite strip and the metal strip, the graphite strip may break, resulting in a reduction in the sealing effect of the low-temperature resistant metal wound gasket. To solve this problem, the embodiments of the present application disclose a method for processing a broken graphite strip. Refer to Figure 3 , the method includes: Step S301: Detect whether the graphite strip breaks during the winding process.

[0068] Exemplarily, a camera is provided on one side of the rotating table. The camera can obtain the real-time image of the graphite strip when the graphite strip and the metal strip are wound synchronously, and determine whether the graphite strip breaks according to the real-time image.

[0069] Step S302: In the case where the graphite strip breaks, obtain the length information of the broken part and the position information of the break point. Among them, the broken part refers to the part of the graphite strip from the starting end to the break point, and the break point includes the first break point on the broken part and the second break point on the graphite strip tape opposite to the broken part.

[0070] In another aspect, in the case where the graphite strip does not break, the process of this embodiment is ended.

[0071] The broken part refers to the part of the graphite strip from the starting end to the break point in the case of a break in the graphite strip, that is, the part of the graphite strip that has been wound but fails to be connected to the subsequent graphite strip. Among them, the graphite strip that fails to be connected to the broken part is defined as the graphite strip material tape.

[0072] The length information refers to the information about 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 can be obtained, so that the length of the broken part can be calculated to obtain the length information.

[0073] The break points include a first break point on the side of the broken part far from the starting section and a second break point on the graphite strip opposite to the broken part.

[0074] The position information indicates the position of the break point during the winding process of the graphite strip and the metal strip, which can be obtained through the real-time image and can reflect the specific position of the break point after the graphite strip breaks.

[0075] Step S303: Determine whether the length corresponding to the length information is less than the preset lower limit length.

[0076] The preset lower limit length is a preset constant, which is related to the length of the broken part and can be adjusted according to actual needs.

[0077] 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, then step S305 is executed; if the length is not less than the preset lower limit length, then step S308 is executed.

[0078] Step S304: If so, control the inner ring to rotate reversely according to the position information so that the broken part is located at the feeding area.

[0079] If so, it means that the length corresponding to the length information is less than the preset lower limit length. Therefore, control the inner ring to rotate reversely according to the position information so that the broken part is located at the feeding area.

[0080] Exemplarily, when the length corresponding to the length information is less than the preset lower limit length, control the inner ring to rotate reversely, and at the same time, the second conveying track works reversely. On the one hand, the graphite strip material tape gradually returns from the wound state to the second conveying track, and on the other hand, the broken part can return to the feeding area.

[0081] Step S305: Blow off the broken part.

[0082] Exemplarily, a blowing head is arranged at the feeding area, and the blowing head sprays gas to blow off the broken part.

[0083] Step S306: Perform the feeding of the graphite strip material tape so that the second break point enters the feeding area.

[0084] Exemplarily, after the broken part is blown off, the second conveying track operates forward, causing the graphite strip to be conveyed towards the feeding area and enabling the second break point to enter the feeding area to abut against the metal strip.

[0085] Step S307: Control the inner ring to rotate so that the graphite strip and the metal strip are wound synchronously.

[0086] Exemplarily, after the second break point enters the feeding area, control the rotating table to rotate forward to drive the inner ring to rotate forward, thereby driving the metal strip to be wound. Under the action of the frictional force of the metal strip, the graphite strip follows the metal strip to be wound synchronously.

[0087] Step S308: If not, control the graphite strip according to a preset docking method.

[0088] If not, it means that the length corresponding to the length information is not less than the preset lower limit length. Therefore, control the graphite strip according to the preset docking method. The specific steps can refer to Figure 4 the embodiment.

[0089] By adopting the above technical solution, when the graphite strip breaks during the winding process, it is possible to blow off the broken part according to the length information and position information of the broken part. When the length corresponding to the length information is less than the preset lower limit length, the graphite strip and the metal strip are wound synchronously again. When the length corresponding to the length information is not less than the preset lower limit length, the graphite strip can be controlled according to the preset docking method, so as to effectively handle the situation of the graphite strip breaking and reduce the probability of the sealing effect of the low-temperature-resistant metal winding gasket decreasing.

[0090] Refer to Figure 4 , the steps of controlling the graphite strip according to the preset docking method include: Step S401: Detect the distance from the first break point to the second break point to obtain the break distance.

[0091] According to the real-time image of the graphite strip, the size of the central angle occupied by the first break point to the second break point can be detected, and the distance from the first break point to the second break point can be calculated according to the distance from the graphite strip to the center of the circle and the size of the occupied central angle, so as to obtain the break distance.

[0092] Step S402: When the break distance is greater than the preset distance, control the inner ring to rotate reversely so that the first break point is located at the feeding area.

[0093] In another aspect, when the break distance is not greater than the preset distance, the process of this embodiment is ended.

[0094] The preset distance is a preset constant, which is related to the distance between the first break point and the second break point and can be adjusted according to actual requirements.

[0095] Exemplarily, when the break distance is greater than the preset distance, it means that the distance between the broken part and the graphite strip is relatively large, resulting in poor sealing effect at this interval. Therefore, by controlling the inner ring to rotate in the reverse direction and the second conveying track to convey in the reverse direction simultaneously, the graphite strip is retracted. When the first break point is located in the feeding area, the rotation of the inner ring and the retraction of the graphite strip are stopped.

[0096] Step S403: Obtain the shape information of the break point.

[0097] Optionally, a first detection camera is provided above the feeding area.

[0098] The first detection camera can take pictures of the first break point and the second break point respectively, and the shape information of the first break point and the second break point can be obtained through edge detection methods.

[0099] Step S404: Determine whether the shape corresponding to the shape information is a preset break shape.

[0100] The preset break shape is a preset shape, which is related to the shape of the break point.

[0101] Exemplarily, when the length of the fracture surface of the break point in the overall length of the graphite strip is less than the width of the graphite strip, it is a preset break shape. When the length of the fracture surface of the break point in the overall length of the graphite strip is not less than the width of the graphite strip, it is a non-preset break shape. Refer to Figure 5 , in the legends, legend a, legend b, legend c and legend d are preset break shapes, while legend e, legend f, legend g and legend h are non-preset break shapes. Referring to legend b, taking the left part as the second break point and the right part as the first break point, the length of the fracture surfaces of the first break point and the second break point in the overall length of the graphite strip is less than the width of the graphite strip, making it easier to dock the first break point and the second break point. Referring to legend f, taking the left part as the second break point and the right part as the first break point, the length of the fracture surfaces of the first break point and the second break point in the overall length of the graphite strip is greater than the width of the graphite strip, making it more difficult to dock the first break point and the second break point. And after docking, due to the longer fracture surface, the docking effect is not good.

[0102] Step S405: If so, control the graphite strip to move towards the feeding area so that the second break point abuts against the first break point.

[0103] If so, it means that the shape corresponding to the shape information is a preset break shape.

[0104] Exemplarily, when the shape corresponding to the shape information is a preset fracture shape, the graphite strip is conveyed forward through the second conveying track in the direction of the feeding area, so that the second fracture point abuts against the first fracture point to complete the docking of the first fracture point and the second fracture point.

[0105] Step S406: Control the inner ring to rotate forward to synchronously wind the graphite strip, the fractured part and the metal strip.

[0106] Exemplarily, after the docking of the first fracture point and the second fracture point is completed, by controlling the rotary table to rotate forward, the inner ring is driven to rotate, thereby driving the graphite strip, the fractured part and the metal strip to be wound synchronously. To prevent the separation of the first fracture point and the second fracture point when the inner ring starts to rotate, the second conveying track conveys the graphite strip forward when the inner ring starts to rotate, so that the first fracture point and the second fracture point always remain in contact to avoid the separation of the first fracture point and the second fracture point.

[0107] Step S407: If not, control the graphite strip according to the preset cutting method.

[0108] If not, it means that the shape corresponding to the shape information is not the preset fracture shape. Therefore, the graphite strip is controlled according to the preset cutting method. The specific steps can refer to Figure 6 the embodiment.

[0109] By adopting the above technical solution, when the length corresponding to the length information of the fractured part is greater than the preset lower limit length and the fracture distance is greater than the preset distance, the shape information of the fracture point is obtained. When the shape corresponding to the shape information is the preset fracture shape, by controlling the movement of the graphite strip, the second fracture point abuts against the first fracture point, and then by rotating the inner ring, the graphite strip, the fractured part and the metal strip are wound synchronously. When the shape corresponding to the shape information is not the preset fracture shape, the graphite strip is controlled according to the preset cutting method. It helps to reduce the gap between the first fracture point and the second fracture point and improve the sealing effect of the low-temperature resistant metal winding gasket.

[0110] Refer to Figure 6 and the steps of controlling the graphite strip according to the preset cutting method include: Step S501: Obtain the first fracture length of the first fracture point and the second fracture length of the second fracture point according to the shape information.

[0111] The first fracture length refers to the length of the graphite strip occupied by the fracture surface of the first fracture point in the length direction of the graphite strip.

[0112] The second fracture length refers to the length of the graphite strip occupied by the fracture surface of the second fracture point in the length direction of the graphite strip.

[0113] Exemplarily, project the fracture surface of the first fracture point onto the length direction of the graphite bar according to the shape information to obtain the first fracture length. Project the fracture surface of the second fracture point onto the length direction of the graphite bar according to the shape information to obtain the second fracture length.

[0114] Step S502: Control the second fracture point to move towards the direction away from the inner ring to the cutting station.

[0115] The cutting station is a station for cutting the graphite bar. In this embodiment, the cutting station is the area where the second cutting assembly is located.

[0116] Exemplarily, the second conveying track conveys the graphite bar strip in the reverse direction, so that the second fracture point is located below the second cutting assembly.

[0117] Step S503: Cut the second fracture point according to the second fracture length to obtain the second cutting point.

[0118] Exemplarily, when the second fracture point is located below the second cutting assembly, the second cutting assembly cuts the second fracture point according to the second fracture length and obtains the second cutting point. Among them, a jet head is arranged on the second cutting assembly, and the cut-off graphite bar is blown off from the second conveying track through the jet head.

[0119] Step S504: Control the inner ring to rotate in the reverse direction so that the first fracture point moves towards the direction of the second fracture point to the cutting station.

[0120] Exemplarily, the rotating table rotates in the reverse direction, so that the fractured part wound around the outside of the inner ring retracts towards the second conveying track, and the first fracture point moves towards the direction of the second fracture point to the cutting station, that is, below the second cutting assembly.

[0121] Step S505: Cut the first fracture point according to the first fracture length to obtain the first cutting point.

[0122] Exemplarily, when the first fracture point is located below the first cutting assembly, the second cutting assembly cuts the first fracture point according to the first fracture length and obtains the first cutting point. Then, the cut-off graphite bar is blown off from the second conveying track through the jet head.

[0123] Step S506: Control the inner ring to rotate in the forward direction so that the first cutting point is located at the feeding area.

[0124] When both the first fracture point and the second fracture point are cut, by controlling the rotating table to rotate in the forward direction, the inner ring rotates in the forward direction, thereby driving the fractured part to wind. When the first cutting point is located at the feeding area, stop the rotation of the inner ring.

[0125] Step S507: Control the graphite strip to move towards the feeding area so that the second cutting point abuts against the first cutting point.

[0126] When the first cutting point is located in the feeding area, control the second conveying track to convey forward so that the second cutting point abuts against the first cutting point.

[0127] Step S508: Control the inner ring to continue to rotate forward so that the graphite strip, the broken part and the metal strip are wound synchronously.

[0128] After the second cutting point abuts against the first cutting point, control the rotating table to rotate forward, thereby controlling the inner ring to continue to rotate forward. Under the action of the frictional force of the metal strip, the graphite strip is wound synchronously with the broken part and the metal strip. Among them, in order to prevent the first cutting point and the second cutting point from separating when the inner ring starts to rotate, the second conveying track conveys the graphite strip forward when the inner ring starts to rotate, so that the first cutting point and the second cutting point always remain in contact to avoid the separation of the first cutting point and the second cutting point.

[0129] By adopting the above technical solution, when the shape corresponding to the shape information is a non-preset fracture shape, the first fracture length of the first fracture point and the second fracture length of the second fracture point are obtained according to the shape information, 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, and then the cut graphite strip, the cut broken part and the metal strip are wound synchronously. This helps to reduce the gap between the graphite strip and the broken part and improve the sealing effect of the low-temperature-resistant metal wound gasket.

[0130] In the following embodiments, the reason for the fracture of the graphite strip may be due to excessive stretching, and the excessive stretching of the graphite strip may cause gaps or cracks in other areas. The existence of gaps or cracks will increase the probability of fracture of the graphite strip. To solve this problem, the embodiments of the present application disclose a method for preventing fracture of the graphite strip. Refer to Figure 7 , the method includes: Step S601: During the process of performing the step of controlling the second fracture point to move towards the direction away from the inner ring to the cutting station, detect whether there are gaps or cracks in the graphite strip within a preset detection length from the second fracture point.

[0131] The preset detection length is a preset length and can be adjusted according to actual needs.

[0132] Exemplarily, a second detection camera is provided at the second cutting assembly. During the execution of step S502, the second detection camera can continuously take real-time pictures of the graphite strip, and analyze according to the pictures taken in real time to determine whether there are gaps or cracks in the graphite strip passing through the second detection camera, and the distance between the gap or crack and the second breaking point is within the preset detection length.

[0133] Step S602: If so, mark the side of the area where the gap or crack is located and away from the second breaking point to obtain a problem marking point.

[0134] 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, so the process of this embodiment ends.

[0135] Among them, if so, it means that a gap or crack is detected in the graphite strip within the preset detection length from the second breaking point. Therefore, mark the side of the area where the gap or crack is located and away from the second breaking point to obtain a problem marking point.

[0136] Step S603: Control the problem marking point to move to the cutting station.

[0137] Exemplarily, when the second conveying track conveys the graphite strip in the reverse direction, when the problem marking point is located below the second cutting assembly, pause the conveying of the graphite strip by the second conveying track.

[0138] Step S604: Perform a cutting operation on the graphite strip according to the problem marking point to cut off the graphite strip corresponding to the problem marking point to the second breaking point.

[0139] Exemplarily, the second cutting assembly cuts the graphite strip according to the problem marking point to cut off the graphite strip corresponding to the problem marking point to the second breaking point.

[0140] By adopting the above technical solution, when there are gaps or cracks in the graphite strip within the preset detection length from the second breaking point, mark the side of the area where the gap or crack is located and away from the second breaking point to obtain a problem marking point, and cut the graphite strip according to the problem marking point. This helps to reduce the probability of the graphite strip breaking due to the existence of gaps or cracks.

[0141] In the following embodiment, internal stress will be generated due to curling deformation during the winding process of the metal strip. Moreover, as the winding radius gradually increases, the linear velocity of the metal strip increases accordingly, and problems such as metal strip relaxation, loose winding, or stress concentration caused by excessive tension are likely to occur. To solve this problem, the embodiment of the present application provides a dynamic tension adjustment method. Refer to Figure 8 , this method includes: Step S701: Control the lower movable wheel set to vibrate up and down at a first preset frequency.

[0142] Refer to Figure 1 , the upper fixed wheel set 131 includes a first fixed wheel 1311 and a second fixed wheel 1312 arranged horizontally in parallel with the first fixed wheel 1311. The lower movable wheel set 132 includes a first movable wheel 1321 and a second movable wheel 1322 arranged horizontally in parallel with the first movable wheel 1321. After the metal strip is output from the first unwinding assembly 11, it sequentially bypasses the first fixed wheel 1311, the first movable wheel 1321, the second fixed wheel 1312, and the second movable wheel 1322 and then enters the first conveying track 12. The lower movable wheel set 132 can vibrate up and down in the vertical direction.

[0143] The first preset frequency is a preset frequency, which is related to the time for the lower movable wheel set to vibrate once and can be adjusted according to actual needs.

[0144] By controlling the lower movable wheel set to vibrate up and down at the first frequency, the metal strip wound around the upper fixed wheel set and the lower movable wheel set can be driven to vibrate accordingly. Through vibration, the stress inside the material can be redistributed in the form of small plastic deformations, so that the local stress concentration area can be relieved, thereby reducing the residual stress of the metal strip.

[0145] Step S702: Continuously monitor the tension value of the metal strip during the rotation of the inner ring.

[0146] The tension value represents the tensile force received by the metal strip during the winding process.

[0147] Exemplarily, force sensors are provided on the upper fixed wheel set and the lower movable wheel set. During the rotation of the inner ring, since the metal strip bypasses the upper fixed wheel set and the lower movable wheel set in sequence, the tension value on the metal strip can be obtained through the force sensors.

[0148] Step S703: Increase the displacement amplitude of the downward vibration of the lower movable wheel set when the tension value is less than the preset lower limit value.

[0149] The preset lower limit value is a preset constant, which is related to the tension of the metal strip and can be adjusted according to actual needs.

[0150] When the tension value is less than the preset lower limit value, it means that the tension on the metal strip is too small, and the metal strip is likely to be wound loosely during winding, resulting in a reduction in the sealing effect of the low-temperature-resistant metal winding gasket. Therefore, the tension on the metal strip needs to be adjusted. When the lower movable wheel set is vibrating up and down, increase the displacement amplitude of the downward vibration of the lower movable wheel set, thereby increasing the tension on the metal strip.

[0151] Exemplarily, the amplitude of the lower movable wheel set during up-and-down vibration is (-A, A), where upward vibration is defined as positive and downward vibration is defined as negative. After increasing the displacement amplitude of the downward vibration of the lower movable wheel set, the amplitude becomes (-A - a, A), where a is the increased vibration amplitude.

[0152] Step S704: When the tension value is greater than the preset lower limit value, increase the displacement amplitude of the upward vibration of the lower movable wheel set.

[0153] The preset lower limit value is a preset constant related to the tension magnitude on the metal strip and can be adjusted according to actual requirements.

[0154] When the tension value is greater than the preset lower limit value, it indicates that the tension on the metal strip is too large, and stress concentration problems are likely to occur due to excessive tension during the winding process of the metal strip. Therefore, it is necessary to adjust the tension on the metal strip. When the lower movable wheel set is vibrating up and down, increase the displacement amplitude of the upward vibration of the lower movable wheel set, thereby reducing the tension on the metal strip.

[0155] Exemplarily, the amplitude of the lower movable wheel set during up-and-down vibration is (-A, A), where upward vibration is defined as positive and downward vibration is defined as negative. After increasing the displacement amplitude of the upward vibration of the lower movable wheel set, the amplitude becomes (-A, A + b), where b is the increased vibration amplitude.

[0156] By adopting the above technical solution, by controlling the lower movable wheel set to vibrate up and down at the first preset frequency, the stress of the metal strip after output can be reduced. By continuously monitoring the tension value of the metal strip, when the tension value is less than the preset lower limit threshold, the tension value of the metal strip can be increased by increasing the amplitude of the downward vibration of the lower movable wheel set, reducing the situation of the metal strip being loose during the winding process. When the tension value is greater than the preset upper limit threshold, the amplitude of the upward vibration of the lower movable wheel set can be increased to reduce the tension value of the metal strip, and the stress concentration problem of the metal strip caused by excessive tension can be improved.

[0157] In the following embodiments, the embodiments of the present application provide a dynamic adjustment method, referring to Figure 9 , the method includes: Step S801: During the synchronous winding process of the graphite strip and the metal strip, control the lower movable wheel set to move upward by a first preset distance according to a first preset speed.

[0158] The second preset speed is negatively correlated with the inner ring rotation duration and can be adjusted according to actual requirements.

[0159] The first preset distance is a preset constant, representing the maximum distance that the lower movable wheel set moves upward and can be adjusted according to actual requirements.

[0160] During the synchronous winding process of the graphite strip and the metal strip, as the winding radius gradually increases, the tension value of the metal strip gradually increases, which in turn leads to an increase in the pressure on the graphite strip, resulting in deformation, damage, or unstable winding of the graphite strip. Therefore, by controlling the lower moving wheel set to move upward by a first preset distance according to a first preset speed, the tension and pressure distribution during the synchronous winding process of the graphite strip and the metal strip are ensured to be uniform.

[0161] Step S802: During the upward movement of the lower moving wheel set, control the lower moving wheel set to vibrate up and down at a second preset frequency.

[0162] 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.

[0163] By controlling the lower moving wheel set to vibrate up and down at a second preset frequency, on the one hand, it can ensure that the metal strip maintains uniform tension during the winding process, avoiding uneven winding or uneven force on the graphite strip caused by tension fluctuations. On the other hand, it can reduce the stress on the metal strip.

[0164] Step S803: During the reverse rotation of the inner ring, perform a rewinding operation on the metal strip through the feeding device.

[0165] The rewinding operation is an operation of winding up the metal strip through the first unwinding component.

[0166] During the reverse rotation of the inner ring, if the metal strip is not wound up, the metal strip may become loose, resulting in uneven winding during subsequent rewinding. Therefore, perform a rewinding operation on the metal strip through the feeding device.

[0167] Exemplarily, when the rotating table rotates in reverse, the first unwinding component drives the metal strip to be wound up, making the tension on the metal strip uniform.

[0168] Step S804: Control the lower moving wheel set to move downward by a second preset distance according to a second preset speed.

[0169] The second preset speed is negatively correlated with the rotation duration of the inner ring and can be adjusted according to actual needs.

[0170] The second preset distance is a preset constant, representing the maximum value of the distance that the lower moving wheel set moves downward, and can be adjusted according to actual needs.

[0171] During the reverse rotation of the inner ring, as the radius of the metal strip winding decreases, the tension on the metal strip decreases, resulting in a decrease in the pressure on the graphite strip. Consequently, when winding the graphite strip subsequently, the tightness between the metal strip and the graphite strip decreases. Therefore, by controlling the lower movable wheel set to move upward by a second preset distance according to the second preset speed, it is ensured that the tension and pressure are evenly distributed between the subsequent graphite strip and the metal strip during the synchronous winding process.

[0172] Step S805: Control the lower movable wheel set to vibrate up and down at a third preset frequency.

[0173] The third preset frequency is a preset constant and can be adjusted according to actual requirements. 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.

[0174] By controlling the lower movable wheel set to vibrate up and down at the third preset frequency, the stress on the metal strip can be effectively reduced, preventing the metal strip from being overstretched or deformed.

[0175] By adopting the above technical solution, on the one hand, during the synchronous winding process of the graphite strip and the metal strip, by controlling the lower movable wheel set to move upward by a first preset distance according to the first preset speed, the tension of the metal strip can be reduced, making the tension and pressure evenly distributed between the graphite strip and the metal strip during the synchronous winding process. On the other hand, during the reverse process of the inner ring, by controlling the lower movable wheel set to move downward by a second preset distance according to the second preset speed, the tension of the metal strip increases, which helps to improve the problem that the tension decreases due to the reduction of the winding radius of the metal strip, and further leads to the decrease of the pressure between the metal strip and the graphite strip.

[0176] Based on the same inventive concept, an embodiment of the present application provides a low-temperature resistant metal wound gasket manufacturing system, including: An acquisition module, configured to acquire length information, position information, fracture distance, shape information, and tension value; A memory, configured to store the program of the above low-temperature resistant metal wound gasket manufacturing method; A processor, the program in the memory can be loaded and executed by the processor and implement the above low-temperature resistant metal wound gasket manufacturing method.

[0177] By adopting the above technical solution, the inner ring is transferred 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 rotation of the inner ring reaches the 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 the 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 grasped to a preset placement position, realizing the automatic production of the low-temperature resistant metal wound gasket and making the production efficiency of the low-temperature resistant metal wound gasket relatively high.
