Description

Technical Field

[0001] The present application relates to the field of sealing gasket manufacturing equipment, and in particular to a winding welding equipment for metal spiral wound gaskets. Background Art

[0002] Metal wound gasket is a sealing gasket with the best resilience among semi-metallic sealing gaskets. The inner ring metal gasket is a type of metal wound gasket. The inner ring metal wound gasket consists of an inner ring and a metal strip wound on the outside of the inner ring. The inner ring metal wound gasket is widely used in the sealing of concave and convex flanges and groove flanges.

[0003] When a metal spiral wound gasket with an inner ring needs to be processed, the worker first places the inner ring on the equipment, welds the metal strip to the inner ring, then winds the metal strip onto the inner ring, and finally welds the tail end of the metal strip to the wound metal strip.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the current equipment is not provided with a welding function, and welding needs to be done manually, which places a high workload on the staff. Summary of the Invention

[0005] In order to reduce the workload of staff, the present application provides a winding welding device for a metal spiral wound gasket.

[0006] The present application provides a winding welding device for a metal spiral wound gasket, which adopts the following technical solution:

[0007] The cam is mounted on the support frame of the machine base and is adapted to move along the axis of rotation of the cam, wherein the cam is mounted on the support frame of the machine base and is adapted to move along the axis of rotation of the cam.

[0008] By adopting the above technical solution, the staff first places the inner ring on the driving assembly, and the driving device drives the inner ring to rotate. When the head end of the metal strip is between the sliding block and the outer wall of the inner ring, the position of the sliding block and the inner ring suddenly changes, and the sliding block moves away from the outer wall of the inner ring. The trigger switch close to the inner ring will contact the trigger block, and the trigger block will trigger the welding gun to weld the metal strip to the inner ring. After that, the metal strip is wrapped around the inner ring during the rotation of the inner ring; then the second spring drives the welding gun to keep the trigger block at a distance from the two trigger switches. As the metal strip completes winding on the inner ring, the sliding block abuts the tail end of the metal strip, and the sliding block moves in the direction of winding around the inner ring. The first spring stretches, and the trigger switch away from the outer ring contacts the trigger block. The trigger block triggers the welding gun for welding, and the welding gun welds the tail end of the metal strip to complete the welding of the metal wound gasket. The welding assembly does not require manual welding, which greatly reduces the labor intensity.

[0009] Optionally, a clamping assembly is provided on the frame, and the clamping assembly includes a first abutment wheel, two second abutment wheels, a first mounting plate, two second mounting plates and an adjusting member, the first mounting plate is slidably connected to the frame, the first abutment wheel is rotatably connected to the first mounting plate, the two second mounting plates are respectively located on both sides of the first mounting plate, the two second abutment wheels correspond one-to-one to the two second mounting plates, the second abutment wheel is rotatably connected to the second mounting plate, and the adjusting member is used to drive the first abutment wheel close to or away from the inner side wall of the metal wound gasket.

[0010] By adopting the above technical solution, the first abutment wheel and the two second abutment wheels abut against the inner ring, so that the inner ring can be positioned. Since the first mounting plate can change its position through the adjusting member, the position of the first abutment wheel is changed, which makes it easier for the staff to remove the inner ring.

[0011] Optionally, the welding assembly is arranged on the first mounting plate, and the sliding block is slidably connected to the first mounting plate along the direction of the first mounting plate.

[0012] By adopting the above technical solution, when the diameter of the inner ring changes, the staff can adjust the position of the first mounting plate and abut the first abutment wheel against the inner wall of the inner ring. Since the welding assembly is arranged on the first mounting plate, the size of the metal wound gasket changes, and the welding assembly can still abut against the outer ring of the metal wound gasket. By arranging the welding assembly on the first mounting plate, the equipment is suitable for producing metal wound gaskets of more sizes, thereby expanding the production application range.

[0013] Optionally, the clamping assembly also includes two connecting rods, the second mounting plate is slidably connected to the frame, the sliding direction of the first mounting plate intersects with the sliding directions of the two second mounting plates at a point, the two connecting rods correspond one-to-one to the two second mounting plates, one end of the connecting rod is arranged on the first mounting plate, and the length direction of the connecting rod is at an acute angle to the sliding direction of the first mounting plate and is not parallel to the sliding direction of the second mounting plate.

[0014] By adopting the above technical solution, due to the relative sliding of the second mounting plate and the connecting rod, when the position of the first mounting plate changes, the position of the second mounting plate can also be changed relatively. The mounting plates are connected by two connecting rods, which improves the adjustment speed of the clamping assembly and makes the center position of the inner ring unchanged, making it easier for the staff to adjust the position of the first mounting plate.

[0015] Optionally, the adjusting member includes an adjusting motor, a first bevel gear, a second bevel gear and a screw, the length direction of the screw is parallel to the sliding direction of the first mounting plate, the screw is rotatably connected to the frame, the first bevel gear is arranged on one end of the screw, the adjusting motor is arranged on the frame, the second bevel gear is arranged on the output shaft of the adjusting motor, and the second bevel gear is engaged with the first bevel gear.

[0018] By adopting the above technical solution, the double-headed motor drives the worm sleeve to rotate, the worm sleeve drives the worm wheel to rotate, the worm wheel drives the two abutment wheels to rotate, and the two abutment wheels drive the inner ring to rotate. When the two mounting plates move relative to each other, the abutment wheels move relative to each other, and the abutment wheels drive the worm wheel to move. Due to the engagement of the worm wheel and the worm, the worm sleeve moves synchronously with the movement of the worm wheel. The worm gear has a self-locking function, and the transmission ratio of the worm gear is high, which is convenient for the rotation of the two abutment wheels clamping the inner ring, and the structure is reasonable.

[0024] By adopting the above technical solution, as the number of turns of the metal strip wrapped around the inner ring gradually increases, the diameter of the metal wound gasket gradually increases, and the sliding block gradually moves away from the center of the inner ring. The sliding block drives the second adjusting rod to rotate, and the second adjusting rod drives the first adjusting rod to rotate through the two-way threaded sleeve.

[0046] The implementation principle of the winding welding equipment of a metal spiral wound gasket in the embodiment of the present application is as follows: the staff puts the inner ring 6 on the first abutment wheel 41 and the two second abutment wheels 42, and then the staff starts the adjusting motor 461, and the adjusting motor 461 drives the second bevel gear 463 to rotate, and the second bevel gear 463 drives the first bevel gear 462 to rotate, and the first bevel gear 462 drives the screw 464 to rotate, and the screw 464 drives the first mounting plate 43 to move downward, and the first abutment wheel 41 moves toward the inner side wall of the inner ring 6, and the two connecting rods 45 move vertically downward, driving the two second mounting plates 44 to move toward the inner side wall of the inner ring 6, and when the first abutment wheel 41 and the two second abutment wheels 42 are all abutted against the inner side wall of the inner ring 6, the staff stops adjusting the cylinder to complete the fixation of the inner ring 6.

[0047] The staff starts the double-headed motor 31, the double-headed motor 31 drives the worm sleeve 33 to rotate, the worm sleeve 33 drives the worm wheel 32 to rotate, the worm wheel 32 drives the two second abutment wheels 42 to rotate, the two second abutment wheels 42 drive the inner ring 6 to rotate, and the two second abutment wheels 42 rotate at the same time, which improves the rotation fixation stability.

[0048] Afterwards, the metal strip 61 passes through the two guide rollers, the cutting knife 51 and the cutting plate 52 until it is between the driven wheel 212 and the inner ring 6. A metal strip 61 appears between the driven wheel 212 that was originally in contact with the inner ring 6. The metal strip 61 drives the driven wheel 212 to move vertically downward. During the vertical downward movement and fixing process of the driven wheel 212, the first spring 23 and the second spring 24 are contracted. Since the second spring 24 needs time to drive the welding gun 22 to move, the trigger switch 25 located above the trigger block 26 contacts the trigger block 26. The trigger switch 25 controls the welding gun 22 to weld the metal strip 61 and the inner ring 6. Then, the inner ring 6 drives the metal strip 61 to wind. Then, the second spring 24 drives the welding gun 22 to move, keeping a distance between the trigger block 26 and the two trigger switches 25. The winding thickness of the metal strip 61 will not change suddenly. The driven wheel 212 moves slowly downward, and the two trigger switches 25 will not contact the trigger block 26.

[0049] As the number of turns of the metal strip 61 increases, the driven wheel 212 drives the driven block 211 to move downward. At this time, the angle between the length direction of the first adjusting rod 562 and the second adjusting rod 563 and the horizontal plane gradually decreases, so that the control rod 561 causes the locking block 54 to overcome the elastic force of the locking spring 55 until the locking block 54 disengages from the locking groove 502 and enters the sliding groove 511. At this time, the cutting knife 51 moves toward the cutting plate 52 under the action of the cutting spring 53. The cutting knife 51 and the cutting plate 52 work together to cut the metal strip 61. The cut metal strip 61 still moves toward the inner ring 6. When the driven wheel 212 passes the tail end of the metal strip 61, the position of the driven wheel 212 suddenly changes, and the driven wheel 212 abuts against the inner ring of the wound metal strip 61, so that the driven wheel 212 moves toward the inner ring 6. At this time, the first spring 23 and the second spring 24 are extended. Similarly, the position of the welding gun 22 will not change instantly at this time, causing the trigger switch 25 located below the trigger block 26 to contact the trigger block 26. The welding gun 22 welds the tail end of the metal strip 61, and then the piston rod of the push-out cylinder 47 is extended, and the welded metal spiral wound gasket is pushed out of the equipment. At this time, the driven wheel 212 loses the inner ring 6 and moves upward under the action of the first spring 23, driving the first adjusting rod 562 and the second adjusting rod 563 to move, driving the control rod 561 away from the locking groove 502. At this time, the piston rod of the reset cylinder 571 is extended, abutting the reset block 572 to clamp the locking block 54 on the cutting knife 51 into the locking groove 502 through the locking spring 55.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
