Description

Technical Field

[0001] The present invention relates to the technical field of metal-clad gasket processing, and in particular to a metal-clad gasket processing edge-wrapping device and its usage method. Background Art

[0002] A metal-clad gasket refers to a composite gasket with a non-metallic material, such as flexible graphite, asbestos rubber sheet, ceramic fiber, etc. inside and a metal thin plate wrapped by a specific cold-working process outside. It is suitable for heat exchangers, pressure vessels, pumps, valves, and flange surface seals, and is also suitable for large-diameter pressure vessels, such as heat exchangers, reactors, cast iron flanges, cylinder heads, boilers, etc. for flange seals. It can also be used for flange seals of various media in pumps, pipe valves, pipelines, and various equipment, and is widely used in industries such as petroleum, chemical, chemical fiber, coal mining, power generation, and metallurgy.

[0003] In the conventional processing process, it is necessary to first bend a metal pipe into a ring structure with a U-shaped cross-section, and then bend it again after filling the filling material. This results in the need for multiple processing equipment to be continuously used in the entire processing process, and an entire processing production line is required to achieve the processing of the entire clad gasket, resulting in a complex processing process and increased production costs.

[0010] A usage method of a metal-clad gasket processing edge wrapping device includes the following steps:

[0011] 1), First, start the driving motor. The rotating driving component drives the rotating disc to rotate, causing the flipping support plate to rotate to a horizontal state. At this time, the supporting mold rotates to an upward state, and the metal tube to be processed is placed in the supporting mold;

[0012] 2), Start the driving motor again. The rotating driving component drives the flipping support plate to rotate to a vertical state. At this time, the side surface of the flipping support plate moves into the rectangular groove of the limiting chuck. At this time, the flipping support plate maintains a vertical state. Start the reciprocating driving component, and the stamping mold reciprocates once in the direction towards the supporting mold. The stamping mold and the supporting mold stamp the metal tube into a U-shaped metal ring with a groove;

[0013] 3), The rotating driving component drives the supporting mold with the U-shaped metal ring to rotate to an upward state again. Fillers are added to the groove of the U-shaped metal ring. Then, the rotating driving component drives the flipping support plate to rotate to a vertical state again. The reciprocating driving component drives the stamping mold to move towards the supporting mold again. During the reciprocating movement of the stamping mold, a flipping action is completed, so that the stamping mold on the other side of the flipping plate contacts the supporting mold. The stamping mold and the supporting mold stamp the U-shaped metal ring with fillers into a closed metal ring;

[0014] 4), The flipping driving component drives the supporting mold with the closed metal ring to continue rotating. During the process of the flipping plate colliding with the supporting bracket, the closed metal ring is separated from the supporting mold, completing the edge wrapping process of the clad gasket.

[0015] Adopting the above technical solutions, the present invention has the following beneficial effects:

[0016] By setting a turning plate with a supporting die to rotate clockwise and counterclockwise respectively to contact two stamping dies, the whole edge wrapping device can complete the stamping process of the metal pipe twice, and fill the material during the stamping gap, so that the whole processing process of the metal-clad gasket is completed by one device.

[0034] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In one embodiment, please refer to Figures 1 - 15, a metal-clad gasket processing edge wrapping device, comprising a base 1, a flipping and supporting mechanism 2, and a flipping and stamping mechanism 3;

[0036] The flipping and supporting mechanism 2 includes a herringbone bracket 4 arranged in the middle of the base 1. The herringbone bracket 4 is vertically arranged on the front and rear sides of the middle of the upper surface of the base 1. The herringbone structure can reduce the volume and weight of the herringbone bracket 4 while maintaining the structural strength of the herringbone bracket 4. The front and rear ends of a horizontally arranged supporting main shaft 5 are rotatably connected to the upper end of the herringbone bracket 4. Rotating disks 6 are arranged on both the front and rear sides of the supporting main shaft 5. The axis of the rotating disk 6 is collinear with the axis of the supporting main shaft 5. A flipping support plate 7 is fixedly connected to the outside of the rotating disk 6. The flipping support plate 7 is of a U-shaped structure. The two feet of the flipping support plate 7 are fixedly connected to the rotating disk 6. A supporting mold 8 is arranged on the side of the flipping support plate 7 away from the rotating disk 6. According to the Figure 2 state description of the positional relationship, the supporting mold 8 is arranged on the right side of the upper surface of the flipping support plate 7. A rotation driving assembly 10 is arranged in the middle of the upper surface of the base 1. The rotation driving assembly 10 can drive the supporting main shaft 5 to rotate;

[0037] The flip punching mechanism 3 includes a protruding bracket 34 arranged on the left side of the upper surface of the base 1, and the front and rear protruding brackets 34 are arranged to be inclined toward the upper left, and the upper end of the protruding bracket 34 is fixedly connected to the front and rear sides of the lower surface of the cross beam 35 arranged in the front and rear directions, and the front and rear ends of the cross beam 35 are slidably connected to the guide sliding column 36 arranged in the left and right directions, and the right end of the guide sliding column 36 is fixedly connected to the fixed block 37, and the middle parts of the front and rear fixed blocks 37 are rotatably connected to the front and rear sides of the punching spindle 38, and the middle part of the punching spindle 38 is fixed. A flip plate 39 is connected, and a stamping die 40 is arranged on both sides of the flip plate 39. One stamping die 40 is a raised annular structure. The stamping die 40 and the supporting die 8 can process the metal tube 61 into a U-shaped metal ring 62. The outer ring and the inner ring of the raised stamping die 40 have a circle of step grooves. When the raised stamping die 40 moves to the right, the inner step groove will contact the left end of the metal tube 61. At this time, the inner step groove will push the metal tube 61 to move to the right, and the right end of the metal tube 61 will move along the inner ring of the supporting die 8. The arc groove at the bottom is bent, and after turning over, it presses against the step groove outside the stamping die 40, so that the tubular metal tube 61 is squeezed into a U-shaped metal ring 62 with a U-shaped structure. The other stamping die 40 is a concave annular structure, which can process the U-shaped metal into a closed metal ring. When the concave stamping die 40 moves to the right, the two side edges on the left side of the U-shaped metal ring 62 will fall into the arc groove inside the stamping die 40, and the side edges of the U-shaped metal ring 62 will be mutually connected along the arc groove inside the stamping die 40. The metal ring 63 is formed by bending together and finally closing together, and a reciprocating drive assembly 49 is arranged in the middle of the crossbeam 35. The reciprocating drive assembly 49 can drive the flip plate 39 to move left and right, and the flip plate 39 can rotate 180 degrees after each left and right movement. Therefore, when the flip plate 39 moves back and forth once from the rightmost end and then returns to the rightmost end again, the flip plate 39 will flip 180 degrees, that is, after the flip plate 39 moves back and forth once, a stamping die 40 will be replaced to perform stamping processing to the right.

[0038] In a case of this embodiment, the reciprocating driving assembly 49 includes a stamping cylinder 43 disposed in the middle of the cross beam 35. The piston rod of the stamping cylinder 43 extends to the right. The piston rod of the stamping cylinder 43 is fixedly connected to a push plate 45 arranged in the front-back direction. The front and rear ends of the push plate 45 are slidably connected to the guiding sliding columns 36. A flat push block 46 is arranged in the middle on the right side of the push plate 45. The push block 46 can better contact the stamping die 40 and drive the stamping die 40 to move to the right. At the same time, a limiting ring 44 is arranged on the left side of the push plate 45. The limiting ring 44 is fixed on the outside of the guiding sliding column 36. Therefore, when the push plate 45 moves to the left, the push plate 45 will contact the limiting ring 44. At this time, the push plate 45 drives the entire guiding sliding column 36 to move through the limiting ring 44. A limiting plate 41 is arranged at the left end of the guiding sliding column 36. A return spring 42 is arranged between the limiting plate 41 and the cross beam 35. The return spring 42 is sleeved outside the guiding sliding column 36. A flipping driving assembly 47 is arranged at the front end of the stamping main shaft 38. The flipping driving assembly 47 can drive the flipping plate 39 to rotate. The flipping plate 39 rotates 90 degrees when it moves once. Therefore, when the flipping plate 39 reciprocates once, it just flips 180 degrees. A flipping positioning assembly 48 is arranged at the rear end of the stamping main shaft 38. The flipping positioning assembly 48 can limit the angle of a single flip of the flipping plate 39 to 90 degrees, so as to ensure that the flipping plate 39 can complete a 180-degree rotation after one reciprocating movement. And because the flipping positioning assembly 48 is set separately, the rotation driving accuracy of the flipping driving assembly 47 is reduced, and it only needs to roughly flip 90 degrees. The angle limiting process is specifically carried out by the flipping positioning assembly 48.

[0039] In a case of this embodiment, the flipping drive assembly 47 includes a cross flipping head 54 disposed at the front end of the stamping main shaft 38. The cross flipping head 54 is composed of two flat plate structures that are perpendicular to each other and cross - arranged. On the upper and lower sides of the front end of the push plate 45, extending plates 50 that extend to the right are provided. On the extending plates 50, a baffle plate 53 and a stopper 51 are provided. The lower surface of the upper extending plate 50 is rotatably connected to the upper end of the baffle plate 53, and a stopper 51 fixedly connected to the extending plate 50 is provided on the right side of the upper baffle plate 53. When the upper baffle plate 53 contacts the stopper 51, the baffle plate 53 is in a vertical state. The stopper 51 will limit the counter - clockwise rotation of the baffle plate 53, and in the natural state, the baffle plate 53 will be in a vertical state. That is to say, if the baffle plate 53 is not subjected to an external force, it will maintain a vertical state in contact with the stopper 51. However, due to the stopper 51 restricting the counter - clockwise rotation of the baffle plate 53, when the baffle plate 53 contacts the cross flipping head 54 from right to left, the baffle plate 53 will push the cross flipping head 54 to rotate counter - clockwise. At this time, the cross flipping head 54 will approximately flip by ninety degrees. However, when the baffle plate 53 moves from left to right, at this time, the baffle plate 53 itself can rotate clockwise to avoid the cross flipping head 54. Therefore, the upper baffle plate 53 will not push the cross flipping head 54 to rotate clockwise. Similarly, the upper surface of the lower extending plate 50 is rotatably connected to the lower end of the lower baffle plate 53, and a stopper 51 fixedly connected to the extending plate 50 is provided on the left side of the lower baffle plate 53. In order to maintain the vertical state of the lower baffle plate 53, the upper ends of the reset counterweight frames 52 are fixedly connected to the front and rear sides of the lower baffle plate 53. Under the action of the gravity of the reset counterweight frames 52, the lower baffle plate 53 will maintain a vertical state in contact with the stopper 51 when not subjected to an external force. When the lower baffle plate 53 moves from right to left, the lower baffle plate 53 will rotate clockwise to avoid the cross flipping head 54. However, when the lower baffle plate 53 moves from left to right, the lower baffle plate 53 will drive the cross flipping shaft to rotate counter - clockwise by ninety degrees due to the interference of the stopper 51. When the baffle plate 53 contacts the cross flipping head 54, due to the action of the reset spring 42, if the baffle plate 53 itself can rotate, the baffle plate 53 will avoid the cross flipping head 54. If the baffle plate 53 itself is restricted by the stopper 51 and cannot rotate, the cross flipping head 54 will rotate adaptively, and there will be no state where the cross flipping head 54 and the baffle plate 53 move horizontally synchronously. To sum up, when the push plate 45 moves to the left, at this time, the upper baffle plate 53 plays a role, and the upper baffle plate 53 drives the cross flipping head 54 to flip by ninety degrees. When the push plate 45 moves to the right, at this time, the lower baffle plate 53 plays a role, and the lower baffle plate 53 drives the cross flipping head 54 to flip by ninety degrees. Thus, after the push plate 45 reciprocates left and right once, the cross flipping head 54 completes a one - hundred - eighty - degree rotation, that is, the flipping plate 39 completes a one - hundred - eighty - degree rotation.The flip positioning assembly 48 includes a positioning column 55 arranged at the rear end of the stamping spindle 38. The positioning column 55 is a columnar structure arranged in line with the stamping spindle 38, and four positioning grooves 56 are arranged on the outer side of the positioning column 55. The angle of the positioning groove 56 is the same as the angle of the plate structure of the cross flip head 54, and corresponds to the left and right sides of the flip plate 39, so that each time the stamping spindle 38 completes a 180-degree flip, the stamping die 40 on the flip plate 39 is just in a left-right facing state. A positioning frame 60 extending to the rear side is arranged on the upper surface of the fixed block 37 on the rear side. The positioning frame 60 is an L-shaped structure. The upper end of the positioning frame 60 is slidably connected to a vertically arranged positioning push rod 58, and the lower end of the positioning push rod 58 is fixedly connected A triangular positioning head 57 with a triangular structure is connected. After the triangular positioning head 57 is inserted into the positioning slot 56, the two side surfaces of the triangular positioning head 57 will just fit with the two side surfaces of the positioning slot 56, thereby achieving a positioning effect. In order to allow the end of the triangular positioning head 57 to slide better during the rotation of the positioning column 55, the lower end of the triangular positioning head 57 is configured to have an arc-shaped structure, and a positioning spring 59 is provided between the positioning frame 60 and the triangular positioning head 57. The positioning spring 59 will push the triangular positioning head 57 to always maintain a downward movement trend, so that the triangular positioning head 57 always maintains a certain pressure in contact with the positioning column 55, so that when the stamping spindle 38 rotates, the triangular positioning head 57 will not separate from the surface of the positioning column 55 to affect the accuracy of the rotation angle.

[0040] In one case of the present embodiment, the rotary drive assembly 10 includes a U-shaped bracket 11 arranged in the middle of the upper surface of the base 1, and a slide groove 20 is arranged on the front and rear sides above the U-shaped bracket 11. A slider 17 is slidably connected to the middle of the slide groove 20. The front and rear sliders 17 are rotatably connected to the front and rear sides of a transmission shaft 19 arranged in front and rear directions. A driving friction wheel 21 is fixedly connected to the middle of the transmission shaft 19, and a driven friction wheel 22 is arranged in the middle of the supporting main shaft 5. The radius of the driven friction wheel 22 is larger than the radius of the rotating disk 6. Therefore, the driven friction wheel 22 can be exposed from between the two rotating disks 6 and contact with the driving friction wheel 21, thereby realizing the rotation of the supporting main shaft 5 through the mutual transmission of the driving friction wheel 21 and the driven friction wheel 22. Support frames 9 are provided on both sides of the herringbone bracket 4. When the flip pallet 7 is at the right end, the lower surface of the flip pallet 7 will contact the upper end of the support frame 9 on the right, and the flip pallet 7 is in a horizontal state. At the same time, when the flip pallet 7 is at the left end, the lower surface of the flip pallet 7 will contact the upper end of the support frame 9 on the left, and the flip pallet 7 is in a horizontal state. That is to say, by setting the two support frames 9 on the left and right sides, the flip pallet 7 can be in a horizontal state when it is rotated to the right or to the left, which ensures the stability of the angle and reduces the requirements for the driving accuracy of the rotation drive component 10.

[0041] In a case of this embodiment, the driven friction wheel 22 is designed to have an elliptical structure, and the major axis of the ellipse is perpendicular to the turning support plate 7. That is to say, when the turning support plate 7 is on the left or right side, the longer radius of the ellipse is oriented vertically. A pressing spring 16 is arranged inside the sliding groove 20. The pressing spring 16 will push the slider 17 upward, so that the driving friction wheel 21 presses tightly against the driven friction wheel 22. A driving motor 14 is arranged at the rear side of the U-shaped bracket 11. The output shaft of the driving motor 14 is fixedly connected with a first transmission wheel 13. The first transmission wheel 13 is connected to a second transmission wheel 18 through a transmission belt 12. The transmission belt 12 itself can be deformed so that the transmission belt 12 always maintains a certain pressure to contact the first transmission wheel 13 and the second transmission wheel 18, but the change in the pressure magnitude will cause the friction force between them to change. The second transmission wheel 18 is fixed to the rear end of the transmission shaft 19. The driving motor 14 realizes the rotation of the transmission shaft 19 through belt transmission. However, when the major axis of the driven friction wheel 22 moves downward, at this time, the driving friction wheel 21 will be pressed downward. At this time, the tension state of the transmission belt 12 is relieved, the pressure between the transmission belt 12 and the first transmission wheel 13 and the second transmission wheel 18 decreases, and the corresponding friction force also becomes smaller. At this time, after the turning support plate 7 contacts the support bracket 9, the driving friction wheel 21 will suddenly stop moving. The first transmission wheel 13 and the driving motor 14 can continue to rotate a certain angle under the action of inertia. At this time, a slight relative displacement will occur between the transmission belt 12 and the second transmission wheel 18 against the friction force. However, when the turning support plate 7 needs to rotate in the reverse direction, at this time, the minimum pressure between the transmission belt 12 and the second transmission wheel 18 can still generate enough friction force to drive the turning support plate 7 to rotate. That is to say, the elliptical structure can reduce the tension degree of the transmission belt 12, so that a relative displacement occurs between the transmission belt 12 and the second transmission wheel 18, but the minimum friction force between the transmission belt 12 and the second transmission wheel 18 can still make the turning support plate 7 start to rotate from the static state. On the one hand, the cooperation between the turning support plate 7 and the support bracket 9 can ensure that the turning support plate 7 maintains a horizontal state, reducing the requirement for the driving accuracy of the rotary driving assembly 10. On the other hand, if the turning plate 39 rotates to the left, the turning plate 39 will collide with the support bracket 9 at this time, and the turning support plate 7 will quickly stop moving. At this time, the transmission belt 12 is disengaged from the second transmission wheel 18, avoiding the sudden stop of the driving motor 14, which can effectively protect the driving motor 14. At the same time, the collision between the turning support plate 7 and the support bracket 9 can also make the closed metal ring 63 placed in the supporting mold 8 fall off, thus realizing the effect of automatic unloading. And in order to prevent the transmission belt 12 from disengaging from the first transmission wheel 13 and the second transmission wheel 18 in the slack state, anti-disengagement frames 15 are arranged at the upper rear side of the back plate 23 and the rear side of the base 1.

[0042] In a case of this embodiment, the flipping pallet 7 realizes the horizontal limiting effect through the supporting brackets 9 on the left and right sides, and an extrusion limiting component 33 is arranged at the rear side of the base 1 to realize the vertical limiting effect of the flipping pallet 7. The extrusion limiting component 33 includes a back plate 23 vertically arranged at the rear end of the upper surface of the base 1. A guiding bracket 31 is arranged at the front side above the back plate 23. The upper and lower sides of the guiding bracket 31 are slidably connected with guiding slide rods 30 arranged in the front-back direction. The front end of the guiding slide rod 30 is fixedly connected with a limiting chuck 32. A rectangular groove is arranged in the middle of the front side of the limiting chuck 32. The rear side surface of the flipping pallet 7 can just fall into the rectangular groove, so as to realize the vertical positioning effect. And the right front end of the front end of the limiting chuck 32 is designed as an inclined surface. Therefore, when the flipping pallet 7 rotates counterclockwise and contacts the limiting chuck 32, the limiting chuck 32 will be pushed backward by the flipping pallet 7, so that the flipping pallet 7 can automatically move into the rectangular groove of the limiting chuck 32. The left front side of the rear end of the guiding slide rod 30 is fixedly connected with the top plate 29. The top plate 29 is located inside the U-shaped guiding bracket 31. And a reinforcing rib is arranged between the front side of the right end of the top plate 29 and the limiting chuck 32 to ensure the stable force of the limiting chuck 32. The front end of a top rod 28 arranged in the front-back direction is fixedly connected to the rear side of the top plate 29. The middle of the top rod 28 is slidably connected with the back plate 23. The rear end of the top rod 28 is fixedly connected with a trapezoidal guiding block 26. The lower surface of the trapezoidal guiding block 26 is an inclined surface. A buffer spring 27 is arranged between the trapezoidal guiding block 26 and the back plate 23. The buffer spring 27 will push the top plate 29 to maintain the trend of moving forward. Therefore, during the process that the flipping pallet 7 rotates counterclockwise and pushes the limiting chuck 32 backward, if the flipping pallet 7 rotates to the vertical state, at this time, the rear side surface of the flipping pallet 7 coincides with the rectangular groove of the limiting chuck 32. At this time, the buffer spring 27 will push the limiting chuck 32 to move forward again, so that the rear side of the flipping pallet 7 sinks into the interior of the rectangular groove, so that the flipping pallet 7 maintains the vertical state at this time to complete the subsequent stamping process. And a lifting cylinder 24 is arranged at the rear side of the back plate 23. The piston rod of the lifting cylinder 24 extends upward, and the piston rod of the lifting cylinder 24 is fixedly connected with a top block 25. After the top block 25 moves upward, it will contact the inclined surface below the trapezoidal guiding block 26. At this time, the top block 25 will push the trapezoidal guiding block 26 to move backward, that is, drag the limiting chuck 32 to move backward to disengage from the flipping pallet 7. At this time, the flipping pallet 7 can continue to rotate.

[0043] A method for using a metal-clad gasket processing edge-sealing device includes the following steps:

[0044] 1. First, start the drive motor 14. The drive motor 14 causes the drive shaft 19 to rotate through the form of belt drive, so that the supporting main shaft 5 rotates through the cooperation of the drive friction wheel 21 and the driven friction wheel 22. The flipping tray 7 rotates clockwise to a state where it contacts the right support bracket 9. At this time, the flipping tray 7 extends to the right and remains horizontal. At this time, the opening of the supporting mold 8 faces upward, and a magnetic attraction device can be set inside the supporting mold 8. At this time, the metal pipe 61 to be processed is placed in the groove of the supporting mold 8, and the magnetic attraction device can ensure that the metal pipe 61 will not easily fall out of the supporting mold 8;

[0045] 2. Start the drive motor 14 again. The rotary drive assembly 10 drives the flipping tray 7 to rotate counterclockwise. At this time, after the flipping tray 7 rotates to the vertical state, it falls into the rectangular groove of the limit chuck 32. At this time, the flipping tray 7 remains in the vertical state, and the supporting mold 8 with the metal pipe 61 is in the left-right orientation state. At this time, the piston rod of the stamping cylinder 43 extends, and the push plate 45 moves to the left first. The baffle 53 under the right side of the push plate 45 will contact the cross flipping head 54. At this time, the protruding stamping die 40 on the flipping plate 39 rotates to the right, and the push plate 45 continues to move. The push block 46 on the push plate 45 contacts the recessed stamping die 40 on the left side. The return spring 42 is compressed at this time. The stamping die 40 moves to the right with the push plate 45. The protruding stamping die 40 and the supporting mold 8 squeeze the metal pipe 61 together, squeezing the metal pipe 61 into a U-shaped metal ring 62 with a groove. Reverse-start the stamping cylinder 43, and the piston rod of the stamping cylinder 43 retracts. The push plate 45 moves to the left, and the return spring 42 returns to its initial state. The protruding stamping die 40 and the supporting mold 8 disengage. At this time, the baffle 53 above the push plate 45 contacts the cross flipping head 54, and the flipping plate 39 rotates counterclockwise by ninety degrees. And when the push plate 45 continues to move to the left, the push plate 45 pulls the guiding sliding column 36 to move to the left through the limit ring 44, and the entire flipping plate 39 moves to the left, completing the processing of one stamping;

[0046] 3. Start the lifting cylinder 24. The push plate 45 moves upward, causing the trapezoidal guide block 26 to move backward. The limit chuck 32 disengages from the turning plate 39. The rotary drive assembly 10 causes the turning plate 39 to rotate clockwise. After the turning support plate 7 rotates, the lifting cylinder 24 can be started in the reverse direction, causing the limit chuck 32 to move to the front side again. The turning plate 39 falls on the right support bracket 9 again to maintain a horizontal state. Put relevant filling materials, such as graphite, asbestos, or ceramic fiber, etc., into the groove of the U-shaped metal ring 62. At this time, the turning plate 39 is driven by the rotary drive assembly 10 to rotate counterclockwise to a vertical state again. The push plate 45 is driven by the reciprocating drive assembly 49 to move to the right. During the process of moving to the right, the push plate 45 causes the turning plate 39 to rotate 90 degrees again through the turning drive assembly 47 and the turning positioning assembly 48, so that the concave stamping die 40 rotates to the right. And the concave stamping die 40 moves to the right with the push plate 45 and contacts the supporting die 8. At this time, the U-shaped metal ring 62 filled with the filling material is extruded into a closed metal ring 63;

[0047] 4. Start the lifting cylinder 24. The limit chuck 32 disengages from the turning support plate 7. The turning drive assembly 47 causes the turning support plate 7 to rotate counterclockwise. The supporting die 8 rotates to the left and downward state. And when the turning support plate 7 impacts the left support bracket 9, the closed metal ring 63 inside the supporting die 8 drops under the action of inertia, thus realizing the discharging effect and completing the edge wrapping process of the entire coated gasket. Repeating the above steps can process a new metal tube 61.

[0048] The present invention is applicable to a metal-coated gasket processing edge wrapping device and its usage method. By setting the turning plate 39 with the supporting die 8 to rotate clockwise and counterclockwise respectively to contact the two stamping dies 40, the entire edge wrapping device can complete the stamping processing of the metal tube 61 twice, and complete the state of the filling material during the stamping gap, so that one device completes the entire processing process of the metal-coated gasket. The whole operation is simple, improving the processing efficiency and reducing the entire processing cost.
