Description

Technical Field

[0001] This utility model relates to the field of sealing spiral wound gasket processing technology, and in particular to a device for chamfering the outer side of the metal ring of a sealing spiral wound gasket. Background Technology

[0002] Spiral wound gaskets are made of graphite and other materials and metal strips wound together. They have many excellent sealing properties, such as thermal stability, self-lubrication, corrosion resistance, non-aging, and non-brittleness. They can be used stably for a long time under harsh working conditions with very little maintenance. In order to ensure their stability, spiral wound gaskets are usually equipped with metal rings on the outer and inner sides. The inner side of the outer metal ring needs to be milled with grooves, and the outer side of the inner metal ring needs to be chamfered.

[0003] In existing methods, when chamfering metal rings, the metal ring is typically fixed directly on a worktable, and then one side of the metal ring is chamfered. After chamfering, the metal ring is flipped over and fixed, and the other side is chamfered to create a wedge shape on the outside of the metal ring. However, chamfering both sides of the metal ring separately results in low chamfering efficiency, which affects the production efficiency of the sealing gasket. Therefore, a chamfering device for the outer side of the metal ring of a sealing winding gasket is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a device for chamfering the outer side of a sealing and winding gasket metal ring. A fixing component can be used to fix the metal ring, while a cross groove, a first cylinder, and a cross plate can drive the fixing component to lift, thereby lifting the metal ring and suspending it in the air. At this point, the driving component and chamfering mechanism can chamfer the metal ring, making the outer side of the metal ring wedge-shaped. This avoids two chamfering operations on the metal ring and improves the chamfering efficiency of the metal ring.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-6 As shown, the present invention proposes a device for chamfering the outer side of a sealing and winding gasket metal ring, which includes a workbench 1, a placement mechanism 2 on the top of the workbench 1, and a chamfering mechanism 3 on the top of the workbench 1.

[0028] In this invention, the placement mechanism 2 can stably place the metal ring and also lift it. After the metal ring is fixed and lifted, the chamfering mechanism 3 can chamfer the metal ring, directly making the metal ring wedge-shaped, avoiding two chamfering operations and greatly improving the chamfering efficiency of the metal ring.

[0029] In an optional embodiment, the placement mechanism 2 includes a placement tray 21, a cross groove 22, four first cylinders 23, a cross plate 24, a limiting component 25, a fixing component 26, and a driving component 27. The placement tray 21 is placed on the top of the worktable 1. The cross groove 22 is formed on the top of the placement tray 21. The cross plate 24 is slidably connected to the inside of the cross groove 22. The four first cylinders 23 are all located on the inner bottom wall of the cross groove 22. The piston rods of the four first cylinders 23 are all connected to the bottom of the cross plate 24. The limiting component 25 is located on the outer end face of the cross plate 24. The fixing component 26 is located on the top of the cross plate 24. The driving component 27 is located on the bottom of the worktable 1. The output end of the driving component 27 is connected to the bottom of the placement tray 21.

[0030] It should be noted that the metal ring can be placed on the placement plate 21. After placement, the metal ring can be fixed by the fixing component 26. After fixing, the four first cylinders 23 are activated. The piston rods of the four first cylinders 23 will drive the cross plate 24 to move upward. The cross plate 24 will drive the fixing component 26 to move upward. The fixing component 26 will drive the metal ring to move upward, so that the metal ring is in a suspended state. Then, the placement plate 21 can be driven to rotate by the drive component 27. The placement plate 21 will drive the metal ring to rotate by the fixing component 26. At this time, the chamfering mechanism 3 can be used to chamfer the metal ring. The limiting component 25 can limit and guide the cross plate 24, so that the movement of the cross plate 24 is stable and the movement trajectory of the cross plate 24 can be limited, so as to prevent the cross plate 24 from disengaging from the cross groove 22 during movement.

[0031] In an optional embodiment, the fixing component 26 includes a vertical plate 261, a second cylinder 262, a movable plate 263, and an abutting arc block 264. The vertical plate 261 is located on the top of the cross plate 24, the second cylinder 262 is located on the right side of the vertical plate 261, the movable plate 263 is located on the piston rod of the second cylinder 262, and the abutting arc block 264 is located on the top of the movable plate 263. The bottom of the abutting arc block 264 corresponds to the top of the placement plate 21.

[0032] It should be noted that when placing the metal ring, the abutting arc block 264 needs to be located inside the metal ring. Then, the second cylinder 262 is activated. The piston rod of the second cylinder 262 will drive the abutting arc block 264 to move outward from the placement plate 21. When the outer side of the abutting arc block 264 abuts against the inner side of the metal ring, the metal ring can be fixed.

[0033] In addition, there are four sets of fixing components 26. The four sets of fixing components 26 are located on the top of the cross plate 24 and are arranged in a circular array. The four sets of fixing components 26 abut and fix the metal ring at four positions, thereby ensuring the stability of the metal ring when it is fixed. At the same time, it can also ensure that the center of the metal ring corresponds to the center of the placement plate 21 after it is fixed.

[0034] In an optional embodiment, the limiting component 25 includes four limiting blocks 251 and four limiting grooves 252. The four limiting blocks 251 are respectively disposed on the outer end face of the cross plate 24, and the four limiting grooves 252 are respectively opened on the inner side wall of the cross groove 22. The four limiting blocks 251 are respectively slidably connected to the inside of the four limiting grooves 252.

[0035] It should be noted that the four limiting blocks 251 and the four limiting grooves 252 can limit and guide the cross plate 24, ensuring the stability of the cross plate 24 when it moves up or down. At the same time, the movement of the cross plate 24 can also be limited to prevent the cross plate 24 from disengaging from the cross groove 22 during movement.

[0036] In an optional embodiment, the drive assembly 27 includes a drive motor 271 and a rotating shaft 272. The drive motor 271 is located at the bottom of the worktable 1, and the rotating shaft 272 is located on the output shaft of the drive motor 271. The top end of the rotating shaft 272 extends to the top of the worktable 1 and is connected to the bottom of the placement tray 21.

[0037] It should be noted that when the drive motor 271 is started, the output shaft of the drive motor 271 will drive the rotating shaft 272 to rotate, and the rotating shaft 272 will drive the placement disk 21 to rotate. Under the action of the fixing component 26, the placement disk 21 will drive the metal ring to rotate, and the metal ring can be chamfered by rotating it.

[0038] In an optional embodiment, the chamfering mechanism 3 includes a mounting base 31, a third cylinder 32, a mounting plate 33, and a chamfering blade 34. The mounting base 31 is located on the top of the workbench 1, the third cylinder 32 is located on the top of the mounting base 31, the mounting plate 33 is located on the piston rod of the third cylinder 32, and the chamfering blade 34 is detachably mounted on the right side of the mounting plate 33. The chamfering blade 34 corresponds to the position of the abutting arc block 264.

[0039] It should be noted that after the metal ring is fixed and lifted, the metal ring is rotated by the drive motor 271. During the rotation, the third cylinder 32 is activated. The piston rod of the third cylinder 32 will drive the mounting plate 33 to move to the right. The mounting plate 33 will drive the chamfering cutter 34 to move to the right. When the chamfering cutter 34 comes into contact with the metal ring, the metal ring can be chamfered by the chamfering cutter 34.

[0040] In addition, the height of the abutting arc block 264 is consistent with the height of the metal ring, and the chamfering blade 34 is positioned corresponding to the abutting arc block 264, ensuring that the chamfering blade 34 can stably perform chamfering operation on the outside of the metal ring when it moves to the right.

[0041] In an optional embodiment, the workbench 1 has base rods 4 at each of its four bottom corners and a controller 5 at its top.

[0042] It should be noted that the worktable 1 is stably supported by four base rods 4, and the first cylinder 23, the second cylinder 262, the drive motor 271 and the third cylinder 32 are all electrically connected to the controller 5. The controller 5 can control the first cylinder 23, the second cylinder 262, the drive motor 271 and the third cylinder 32.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
