Description

Technical Field

[0001] This application relates to the field of metal spiral wound gasket production technology, specifically to a metal spiral wound gasket production apparatus and process. Background Technology

[0002] Spiral wound gaskets are sealing elements used at flange connections in pipes, valves, and pressure vessels. They are made of metal strips and non-metallic materials wound together, and have good elasticity and sealing performance. Spiral wound gaskets generally consist of metal strips, non-metallic fillers, locating rings, and outer rings.

[0003] Metal spiral wound gaskets are divided into those with and without filters. Those with filters have a filtering function. The manufacturing process involves welding the filter and positioning ring together, followed by winding the metal strip and non-metallic filler. During winding, the sidewalls of the metal strip and positioning ring are welded first, and then the metal strip and non-metallic filler are wound alternately. After winding to a certain extent, the outer ring is fitted onto the winding layer, and the inner and outer rings are welded together as needed.

[0004] Referring to the Chinese patent document with announcement number CN211315090U entitled "A Metal Spiral Wound Gasket", the device uses a U-shaped groove on the outer ring of the metal spiral wound gasket, which can improve the extensibility and resilience of the metal spiral wound gasket to a certain extent, thereby effectively ensuring the sealing performance of the metal spiral wound gasket.

[0005] Regarding the above technical solution, when producing metal spiral wound gaskets with filters, an outer ring is needed to fix the wound layer after winding. In order to reduce the damage of non-metallic fillers caused by high welding temperatures and to reduce the resilience and creep resistance of the gasket caused by welding, the metal strip is usually not welded when fixing the wound layer with the outer ring. During the production process, because the metal strip is not welded, it is easy for the metal strip to become loose when the outer ring is put on, which makes it impossible for the gasket to form a uniform and dense sealing layer, causing the sealing performance of the metal spiral wound gasket to fail. Summary of the Invention

[0006] In view of this, this application provides a metal spiral wound gasket production apparatus and process, which aims to solve the problem of loosening of the spiral wound layer during the installation of the outer ring.

[0007] In a first aspect, this application provides a metal spiral wound gasket production apparatus, comprising:

[0008] The metal spiral wound gasket production apparatus provided in this application adopts the following technical solution, including a placement frame and a core-setting mechanism disposed on the placement frame; a push cylinder is fixedly connected to the placement frame, an abutment spring is fixedly connected to the output shaft of the push cylinder, a sliding block is fixedly connected to the end of the abutment spring away from the abutment cylinder, and the sliding block is slidably connected to the placement frame; an abutment wheel is rotatably connected to the sliding block, the abutment wheel is used to abut against the side wall of the positioning ring; a clamping block is slidably connected to the sliding block, and a clamping wheel is rotatably connected to the clamping block, the clamping wheel is used to clamp the metal strip after winding.

[0009] The push cylinder is activated, and its output shaft extends forward. As the push cylinder output shaft extends forward, the abutment spring connected to the output shaft is compressed, with the other end of the spring fixedly connected to a sliding block. The compression of the abutment spring causes the sliding block to slide along the guide rail of the placement frame, moving towards the centering mechanism. The abutment wheel rotatably connected to the sliding block also moves accordingly, and when the sliding block reaches the predetermined position, the abutment wheel tightly abuts against the side wall of the positioning ring, thereby fixing the positioning ring. At the same time, a clamping block is also slidably connected to the sliding block, and the clamping block moves with the movement of the sliding block. A clamping wheel is rotatably connected to the clamping block. After the metal strip is wound, the clamping wheel functions to clamp the metal strip, ensuring that the metal strip is tightly against the positioning ring and preventing loosening.

[0010] The tensioning rollers maintain the tension of the metal strip after winding, ensuring it doesn't loosen and thus preserving the structure's stability and strength. By securing the metal strip with the tensioning rollers, misalignment of the metal strip on the positioning ring is reduced, improving winding accuracy and consistency. The tensioning rollers ensure the metal strip is firmly fixed to the positioning ring, reducing potential malfunctions and problems during subsequent processing or use.

[0011] Optionally, an abutting cylinder is fixedly connected to the sliding block, a connecting block is fixedly connected to the output shaft of the abutting cylinder, and an auxiliary rotating wheel is rotatably connected to the connecting block. The auxiliary rotating wheel is used to assist the abutting wheel in abutting.

[0012] The auxiliary roller helps distribute the pressure on the metal strip as well as the clamping roller, resulting in a more even distribution of the clamping force and reducing damage caused by excessive pressure at a single point. The addition of the auxiliary roller increases the stability of the entire clamping system, helping to maintain the position of the metal strip on the positioning ring and preventing displacement during processing.

[0013] Optionally, a connecting cylinder is fixedly connected to the sliding block, a connecting spring is fixedly connected to the output shaft of the connecting cylinder, a control handle is rotatably connected to the sliding block, and a torsion spring is fixedly connected at the connection between the control handle and the sliding block.

[0014] Optionally, a wiring block is fixedly connected to the sliding block, the wiring block has a first feeding port for passing through the metal strip, and a second feeding port is provided at the end of the wiring block away from the metal strip, the second feeding port being used to allow the non-metal strip to pass through.

[0015] Optionally, a cutting block is slidably connected to the sliding block, the cutting block is disposed on the sliding block near one end of the wiring block, a first cutter is fixedly connected to the cutting block and the first cutter extends into the wiring block, the first cutter is used to cut non-metallic strips, a second cutter is fixedly connected to the cutting block and the second cutter is used to cut metal strips, and a return spring is fixedly connected to the cutting block, the end of the return spring away from the cutting block is fixedly connected to the wiring block.

[0016] Optionally, the control throttle can abut against the cutting block, and when the control throttle is rotated, it can push the cutting block to move toward the side closer to the wiring block. The connecting cylinder and the abutting cylinder are connected.

[0017] The movement of the auxiliary rollers allows for precise control of the outer ring's installation position, ensuring alignment between the outer ring and the center of the gasket, preventing eccentricity or misalignment, and thus improving installation accuracy. The movement of the auxiliary rollers provides a suitable installation position for the outer ring, and the contact of the clamping rollers during installation reduces loosening of the winding layer, making it easier to fit the outer ring into the designated position, simplifying the operation and reducing installation difficulty.

[0018] Optionally, a reinforcing block is fixedly connected to the axial sidewall of the abutting wheel. The reinforcing block is used to reduce the offset of the metal strip and non-metal strip during the winding process.

[0019] Reinforcing blocks help ensure the alignment of metal and non-metal strips during winding, reducing misalignment and thus improving winding accuracy. Reinforcing blocks provide additional support to the contact rollers, making the entire winding system more stable and reducing vibrations that may occur during high-speed or high-pressure winding. Reinforcing blocks can limit lateral movement of the metal and non-metal strips during winding, preventing uneven or loose winding layers caused by misalignment.

[0020] Optionally, the core-setting mechanism includes a rotating motor fixedly connected to a placement frame, and a diaphragm chuck rotatably connected to the placement frame, the diaphragm chuck being used to core the core-setting ring.

[0021] The function of the mandrel is to ensure that the metal and non-metal strips remain concentric during the winding process. By using a diaphragm chuck to center the mandrel, its position can be precisely controlled, thereby ensuring the concentricity of the metal and non-metal strips during winding, and ultimately guaranteeing the dimensional accuracy and sealing performance of the final gasket.

[0022] Secondly, a metal spiral wound gasket manufacturing process is applied to a metal spiral wound gasket manufacturing device. The process is as follows: S1, the core ring to be wound is placed on a diaphragm chuck, and the diaphragm chuck is adjusted to core the core ring. The rotating motor is started to drive the diaphragm chuck to rotate. The push cylinder is started to drive the sliding block to move toward the diaphragm chuck, and the reinforcing block abuts against both sides of the core block. During the movement of the sliding block, the abutment wheel moves toward the core ring.

[0023] S2, weld the filter screen onto the core ring, and start the abutment cylinder to move the auxiliary rotating wheel toward the core ring and pull the metal strip to weld the metal strip onto the core ring. Rotate the motor to rotate the diaphragm chuck so that the metal strip is wound around once and the non-metallic strip is abutted against the welded part of the metal strip, and the winding continues.

[0024] The abutment roller provides a stable reaction force during the winding process, ensuring that the metal and non-metal strips maintain appropriate tension and tightness, preventing excessively loose or tight winding, thus guaranteeing consistent and uniform winding quality. The abutment roller also buffers the impact forces generated during winding, protecting the core ring and winding material from damage and extending their service life. Furthermore, the presence of the abutment roller reduces the need for manual adjustments, improving the automation and efficiency of the winding process.

[0025] Optionally, in step S2, after the winding reaches a certain thickness, the control handle is rotated to push the cutting block toward one side of the wiring block, cutting the metal and non-metal strips. When the control handle rotates, the connecting spring pushes the output shaft of the connecting cylinder to move, creating a negative pressure in the connecting cylinder. Since the connecting cylinder is connected to the abutting cylinder, this negative pressure attracts the gas in the abutting cylinder to flow to the connecting cylinder, thereby driving the output shaft of the abutting cylinder to retract and causing the auxiliary rotating wheel to move away from the centering ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel has moved, and the outer ring is installed.

[0026] The abutting roller can effectively prevent the metal and non-metal strips from slipping or misaligning during the winding process, ensuring the neatness and stability of the winding.

[0027] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0028] 1. The tensioning roller maintains the tension of the metal strip after winding, ensuring it doesn't loosen and thus maintaining the stability and strength of the structure. By securing the metal strip with the tensioning roller, offset of the metal strip on the positioning ring is reduced, improving the accuracy and consistency of winding. The tensioning roller ensures the metal strip is firmly fixed to the positioning ring, reducing potential malfunctions and problems during subsequent processing or use.

[0029] 2. The auxiliary roller helps to distribute the pressure on the metal strip as well as the clamping roller, resulting in a more even distribution of the clamping force and reducing damage caused by excessive pressure at a single point. The addition of the auxiliary roller increases the stability of the entire clamping system, helping to maintain the position of the metal strip on the positioning ring and preventing displacement during processing.

[0030] 3. The movement of the auxiliary rotating wheel allows for precise control of the outer ring's installation position, ensuring alignment between the outer ring and the center of the gasket, preventing eccentricity or misalignment, and thus improving installation accuracy. The movement of the auxiliary rotating wheel provides an installation position for the outer ring, and during installation, the contact of the clamping wheel reduces loosening of the winding layer, making it easier to fit the outer ring into the designated position, making operation more convenient and reducing installation difficulty.

[0031] 4. The abutment roller provides a stable reaction force during the winding process, ensuring that the metal and non-metal strips maintain appropriate tension and tightness, preventing excessively loose or tight winding, thus guaranteeing consistent and uniform winding quality. The abutment roller also buffers the impact forces generated during winding, protecting the core ring and winding material from damage and extending their service life. The presence of the abutment roller reduces the need for manual adjustments, improving the automation and efficiency of the winding process. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-7 The technical solutions of the embodiments of this application are clearly and completely described herein. All other embodiments obtained by those skilled in the art based on the described embodiments are within the scope of protection of this application.

[0041] In a first aspect, this application provides a metal spiral wound gasket production apparatus, comprising:

[0042] like Figure 1 As shown, this embodiment provides a metal spiral wound gasket production apparatus including a placement frame 1, a core-setting mechanism 2, an abutment mechanism, a wiring mechanism, an auxiliary mechanism, and a cutting mechanism. The placement frame 1 is placed on a horizontal surface. The core-setting mechanism 2 is used to core the core-setting ring. The abutment mechanism is used to abut against the side wall of the core-setting ring to assist in the winding of the spiral wound layer. The wiring mechanism is used to abut against the core-setting ring with the metal strip and non-metal strip. The auxiliary mechanism is used to assist in the winding of the spiral wound layer and reduce the loosening of the spiral wound layer. The cutting mechanism is used to cut the metal strip and non-metal strip.

[0043] like Figure 1 As shown, the core-setting mechanism 2 includes a rotary motor 21 and a diaphragm chuck 22. The rotary motor 21 is fixedly connected to the placement frame 1, and the diaphragm chuck 22 is rotatably connected to the placement frame 1. The output shaft of the diaphragm chuck 22 and the rotary motor 21 are fixedly connected. When it is necessary to fix the core-setting ring, the diaphragm chuck 22 is rotated to fix the core-setting ring, and the filter screen is welded to the core-setting ring. The rotary motor 21 is started to rotate the output shaft of the rotary motor 21, which drives the core-setting ring to rotate, and the operator fixes various parts of the core-setting ring.

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the abutting mechanism includes a push cylinder 3, an abutting spring 31, a sliding block 32, and an abutting wheel 33. The push cylinder 3 is fixedly connected to the placement frame 1, the abutting spring 31 is fixedly connected to the output shaft of the push cylinder 3, the sliding block 32 is slidably connected to the placement frame 1, and the end of the sliding block 32 away from the placement frame 1 is fixedly connected to the abutting spring 31. The abutting wheel 33 is rotatably connected to the sliding block 32, and a reinforcing block 7 is fixedly connected to the axial side wall of the abutting wheel 33. The reinforcing block 7 is used to reduce the deviation of the metal strip and the non-metal strip during winding.

[0045] When it is necessary to fix the core ring, the push cylinder 3 is activated, causing the output shaft of the push cylinder 3 to extend forward. After the output shaft of the push cylinder 3 extends forward, it drives the sliding block 32 to move toward the core block. The abutting wheel 33 located on the sliding block 32 abuts against the side wall of the welded core ring. Due to the buffering of the abutting spring 31, the sliding block 32 is in a state that can extend and retract and abut against the side wall of the core ring.

[0046] like Figure 3 and Figure 4 As shown, the auxiliary mechanism includes a clamping block 34, a clamping wheel 35, a clamping cylinder 4, a connecting block 41, and an auxiliary rotating wheel 42. The clamping block 34 is slidably connected to the sliding block 32, and a spring is provided on the clamping block 34. The clamping wheel 35 is rotatably connected to the clamping block 34 and is used to clamp against the wound metal and non-metal strips. The clamping cylinder 4 is fixedly connected to the sliding block 32. The connecting block 41 is fixedly connected to the output shaft of the clamping cylinder 4. The auxiliary rotating wheel 42 is rotatably connected to the connecting block 41.

[0047] When the sliding block 32 moves toward the centering ring, the clamping wheel 35 located on the sliding block 32 abuts against the side wall of the centering ring, and welds the joint of the metal strip to the centering ring, causing the centering ring to rotate. During the rotation, the clamping wheel 35 always abuts against the side wall of the centering ring. When the centering ring is abutted, the output shaft of the abutting cylinder 4 extends forward, causing the connecting block 41 and the auxiliary rotating wheel 42 to move toward the centering ring, so that the auxiliary rotating wheel 42 abuts against the centering ring. After abutting, the spring located on the clamping block 34 is in a compressed state. When the sliding block 32 moves away from the centering block, the spring pushes the clamping block 34 to continue abutting against the winding layer, reducing the probability of the winding layer becoming loose.

[0048] like Figure 6 and Figure 7As shown, the wiring mechanism includes a wiring block 6, a first feed port 61, and a second feed port 62. The wiring block 6 is fixedly connected to the sliding block 32. The first feed port 61 is opened on the wiring block 6 and is used to pass metal strip. The second feed port 62 is opened on the wiring block 6 and is located at one end of the wiring block 6 away from the first feed port 61. The second feed port 62 is used to pass non-metallic strip.

[0049] The metal strip is placed in the first feed port 61 and the non-metallic strip is placed in the second feed port 62. When it is necessary to wind the mandrel, the metal strip is pulled so that it abuts against the side wall of the mandrel and is welded to the side wall of the mandrel. The mandrel is rotated so that the metal strip first winds around the mandrel once. After winding, the non-metallic strip is abutted against the metal strip. The metal strip and the non-metallic strip are wound synchronously until a certain thickness is reached.

[0050] like Figure 6 and Figure 7 As shown, the cutting mechanism includes a connecting cylinder 5, a connecting spring 51, a control handle 52, a cutting block 63, a first cutter 64, a second cutter 65, and a return spring 66. The connecting cylinder 5 is fixedly connected to the sliding block 32, the connecting spring 51 is fixedly connected to the output shaft of the connecting cylinder 5, the control handle 52 is rotatably connected to the sliding block 32, and a torsion spring is provided at the connection between the control handle 52 and the sliding block 32. The torsion spring can drive the control handle 52 to return to its original position. The cutting block 63 is slidably connected to the sliding block 32, and the cutting block 63 is located at one end of the sliding block 32 near the wiring block 6. The first cutter 64 is fixedly connected to the cutting block 63 and extends into the wiring block 6. The first cutter 64 is used to cut the metal strip. The second cutter 65 is fixedly connected to the cutting block 63 and is used to cut the metal strip. The return spring 66 is fixedly connected to the cutting block 63, and the end of the return spring 66 away from the cutting block 63 is fixedly connected to the wiring block 6.

[0051] When it is necessary to cut the metal strip and the non-metal strip, rotate the control handle 52 so that the control handle 52 abuts against the cutting block 63 and pushes the cutting block 63 to move toward one side of the wiring block 6. The first cutter 64 on the cutting block 63 cuts the non-metal strip, and the second cutter 65 on the cutting block 63 cuts the metal strip. After cutting, the control handle 52 is reset under the action of the torsion spring.

[0052] like Figure 6 As shown, the control handle 52 can abut against the cutting block 63, and when the control handle 52 is rotated, it can push the cutting block 63 to move toward the side closer to the wiring block 6. The connecting cylinder 5 and the abutting cylinder 4 are connected through the air passage.

[0053] When the control throttle 52 is turned, the connecting spring 51 pushes the output shaft of the connecting cylinder 5 to move, causing the connecting cylinder 5 to form a negative pressure. Since the connecting cylinder 5 and the abutting cylinder 4 are connected through an air passage, this negative pressure attracts the gas in the abutting cylinder 4 to flow towards the connecting cylinder 5, thereby driving the output shaft of the abutting cylinder 4 to retract and causing the auxiliary rotating wheel 42 to move away from the centering ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel 42 has moved, thus installing the outer ring.

[0054] In use, the core ring to be wound is placed on the diaphragm chuck 22, and the diaphragm chuck 22 is adjusted to core the core ring. The rotating motor 21 is started to drive the diaphragm chuck 22 to rotate. The pushing cylinder 3 is started to drive the sliding block 32 to move toward the diaphragm chuck 22, and the reinforcing block 7 abuts against both sides of the core block. During the movement of the sliding block 32, the abutting wheel 33 moves toward the core ring.

[0055] The filter screen is welded onto the core ring, and the abutment cylinder 4 is activated, causing the abutment cylinder 4 to move the auxiliary rotating wheel 42 toward the core ring and pull the metal strip to weld the metal strip onto the core ring. The rotating motor 21 rotates, causing the diaphragm chuck 22 to rotate, so that after the metal strip is wound around once, the non-metallic strip is abutted against the welded part of the metal strip, and the winding continues.

[0056] After the winding reaches a certain thickness, rotate the control handle 52 to push the cutting block 63 toward one side of the wiring block 6 to cut the metal and non-metal strips. When the control handle 52 rotates, the connecting spring 51 pushes the output shaft of the connecting cylinder 5 to move, so that the connecting cylinder 5 forms a negative pressure. This negative pressure attracts the gas in the abutment cylinder 4 to flow toward the connecting cylinder 5, and moves the auxiliary rotating wheel 42 away from the core ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel 42 has moved, and the outer ring is installed.

[0057] In this embodiment, after the winding layer is wound, the clamping wheel 35 clamps the winding layer to reduce the gap between the metal strips, thereby improving the overall tightness. The clamped winding layer can better transmit and bear the force, enhancing the structural strength and stability of the metal winding sheet.

[0058] In this embodiment, the auxiliary roller 42 can provide additional support force to the core ring when it abuts against the core ring, helping to maintain the stability of the core ring and ensure the accuracy of the metal strip joint during the welding process. When the sliding block 32 moves away from the core block, the spring pushes the clamping block 34 to continue to abut against the winding layer, which helps to maintain the tightness of the winding layer and reduce the probability of the winding layer becoming loose.

[0059] In this embodiment, the abutment spring 31 can absorb and buffer the impact force caused by the movement of the cylinder 3 or external vibration, preventing these forces from acting directly on the core ring and the sliding block 32, thereby protecting the mechanical parts from damage.

[0060] In this embodiment, the spring maintains a certain pressure to ensure that the contact wheel 33 always remains in contact with the side wall of the centering ring, thereby maintaining a fixed contact state and preventing poor welding or displacement of the centering ring due to insufficient pressure. By selecting springs with different elastic coefficients, the pressure applied to the centering ring can be adjusted to adapt to the requirements of different materials and processes.

[0061] In this embodiment, the abutting roller 33 can evenly distribute the force applied by the pushing cylinder 3 onto the sidewall of the centering ring, avoiding deformation or damage to the centering ring due to excessive local pressure. The contact between the abutting roller 33 and the sidewall of the centering ring helps stabilize the position of the centering ring, reducing vibration during welding or other processing, thereby improving operational accuracy. The roller design typically reduces friction between the sliding block 32 and the centering ring, as rolling friction is much lower than sliding friction, which helps protect the surface quality of the centering ring.

[0062] Secondly, a metal spiral wound gasket manufacturing process is applied to a metal spiral wound gasket manufacturing apparatus, the process comprising:

[0063] S1, place the core ring to be wound on the diaphragm chuck 22 and adjust the diaphragm chuck 22 to core the core ring. Start the rotating motor 21 to drive the diaphragm chuck 22 to rotate. Start the push cylinder 3 to drive the sliding block 32 to move toward the diaphragm chuck 22 and make the reinforcing block 7 abut against both sides of the core block. During the movement of the sliding block 32, it drives the abutting wheel 33 to move toward the core ring.

[0064] S2, weld the filter screen onto the core ring, and start the abutment cylinder 4, so that the abutment cylinder 4 drives the auxiliary rotating wheel 42 to move toward the core ring and pull the metal strip to weld the metal strip onto the core ring. Rotate the motor 21 to drive the diaphragm chuck 22 to rotate, so that after the metal strip is wound around once, the non-metallic strip is abutted against the welded part of the metal strip, and the winding continues.

[0065] In step S2, after the winding reaches a certain thickness, the control handle 52 is rotated, causing the control handle 52 to push the cutting block 63 toward one side of the wiring block 6 to cut the metal and non-metal strips. When the control handle 52 rotates, the connecting spring 51 pushes the output shaft of the connecting cylinder 5 to move, causing the connecting cylinder 5 to form a negative pressure. Since the connecting cylinder 5 is connected to the abutting cylinder 4, the negative pressure attracts the gas in the abutting cylinder 4 to flow to the connecting cylinder 5, thereby driving the output shaft of the abutting cylinder 4 to retract and causing the auxiliary rotating wheel 42 to move away from the centering ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel 42 has moved, and the outer ring is installed.

[0066] The implementation principle of a metal spiral wound gasket production device and process in this application embodiment is as follows: the core ring to be wound is placed on the diaphragm chuck 22, and the diaphragm chuck 22 is adjusted to core the core ring. The rotating motor 21 is started to drive the diaphragm chuck 22 to rotate. The pushing cylinder 3 is started to drive the sliding block 32 to move toward the diaphragm chuck 22, and the reinforcing block 7 abuts against both sides of the core block. During the movement of the sliding block 32, the abutting wheel 33 moves toward the core ring.

[0067] The filter screen is welded onto the core ring, and the abutment cylinder 4 is activated, causing the abutment cylinder 4 to move the auxiliary rotating wheel 42 toward the core ring and pull the metal strip to weld the metal strip onto the core ring. The rotating motor 21 rotates, causing the diaphragm chuck 22 to rotate, so that after the metal strip is wound around once, the non-metallic strip is abutted against the welded part of the metal strip, and the winding continues.

[0068] After the winding reaches a certain thickness, rotate the control handle 52 to push the cutting block 63 toward one side of the wiring block 6 to cut the metal and non-metal strips. When the control handle 52 rotates, the connecting spring 51 pushes the output shaft of the connecting cylinder 5 to move, creating a negative pressure in the connecting cylinder 5. This negative pressure attracts the gas in the abutment cylinder 4 to flow toward the connecting cylinder 5, causing the output shaft of the abutment cylinder 4 to retract and move the auxiliary rotating wheel 42 away from the centering ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel 42 has moved, thus installing the outer ring.

[0069] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.

The first cutter (64) is used to cut non-metallic strips. A second cutter (65) is fixedly connected to the cutting block (63), and the second cutter (65) is used to cut metal strips. A return spring (66) is fixedly connected to the cutting block (63), and the end of the return spring (66) away from the cutting block (63) is fixedly connected to the wiring block (6).

5. The metal spiral wound gasket production apparatus according to claim 4, characterized in that: A reinforcing block (7) is fixedly connected to the axial side wall of the abutting wheel (33). The reinforcing block (7) is used to reduce the deviation of the metal strip and non-metal strip during the winding process.

6. The metal spiral wound gasket production apparatus according to claim 5, characterized in that: The core-setting mechanism (2) includes a rotating motor (21) fixedly connected to the placement frame (1), and a diaphragm chuck (22) rotatably connected to the placement frame (1). The diaphragm chuck (22) is used to set the core-setting ring.

7. A metal spiral wound gasket manufacturing process, applied to the metal spiral wound gasket manufacturing apparatus of claim 6, the process comprising: S1, place the core ring to be wound on the diaphragm chuck (22) and adjust the diaphragm chuck (22) to core the core ring. Start the rotating motor (21) to drive the diaphragm chuck (22) to rotate. Start the push cylinder (3) to drive the sliding block (32) to move toward the diaphragm chuck (22) and make the reinforcing block (7) abut against both sides of the core block. During the movement of the sliding block (32), drive the abutting wheel (33) to move toward the core ring. S2, weld the filter screen onto the core ring, and start the abutment cylinder (4) to make the abutment cylinder (4) drive the auxiliary rotating wheel (42) to move toward the core ring and pull the metal strip to weld the metal strip onto the core ring. Rotate the motor (21) to drive the diaphragm chuck (22) to rotate, so that the metal strip is wound around once and the non-metal strip is abutted against the weld of the metal strip and the winding continues.

8. The metal spiral wound gasket manufacturing process according to claim 7, characterized in that: In step S2, after the winding reaches a certain thickness, the control handle (52) is rotated to push the cutting block (63) toward one side of the wiring block (6) to cut the metal strip and non-metal strip. When the control handle (52) rotates, the connecting spring (51) pushes the output shaft of the connecting cylinder (5) to move, so that the connecting cylinder (5) forms a negative pressure. Since the connecting cylinder (5) is connected to the abutting cylinder (4), the negative pressure attracts the gas in the abutting cylinder (4) to flow to the connecting cylinder (5), thereby driving the output shaft of the abutting cylinder (4) to retract and causing the auxiliary rotating wheel (42) to move away from the core ring. The outer ring is then fitted onto the position after the auxiliary rotating wheel (42) has moved, and the outer ring is installed.
