Description

Technical Field

[0001] This invention relates to the field of gasket welding equipment, and in particular to a welding and forming processing device for irregularly shaped metal gaskets. Background Technology

[0002] In the production and processing of irregularly shaped metal gaskets, square metal gaskets are widely used due to their adaptability to various flange sealing requirements. During the production and processing of square metal gaskets, the quality of the butt welding at both ends directly determines the sealing performance and safety of use. Existing welding equipment for square metal gaskets has significant technical defects. When welding the gasket ends, it is difficult to achieve precise positioning, easily leading to misalignment and displacement of the ends, resulting in poor weld quality and affecting the sealing effect. Furthermore, existing equipment cannot remove impurities at the gasket end joint, easily causing problems such as incomplete penetration, weak welds, and cracks in subsequent welds, failing to ensure sealing performance during welding. Summary of the Invention

Two sets of connecting rods are fixedly mounted between the two sets of connecting plates. A wiping component is provided inside the fixing frame.

[0006] Preferably, the wiping assembly includes a movable shaft movably disposed inside the fixed frame. Two sets of rings are fixedly disposed on the outer side of the movable shaft. A support plate is fixedly disposed on the upper side of the rings. A U-shaped spring is fixedly disposed on the upper side of the support plate. Cleaning blocks are fixedly disposed at both ends of the U-shaped spring. A ratchet is disposed between the two sets of rings outside the movable shaft. An arc-shaped rack is fixedly disposed on the outer shell of the ratchet. Torsion springs are sleeved on both sides of the movable shaft between the two sets of rings and the inner wall of the fixed frame. A connecting sleeve is sleeved on the lower set of the two sets of connecting rods. A straight rack is fixedly disposed at the front end of the connecting sleeve.

[0007] Preferably, the outer side of the threaded rod is provided with two opposite spiral patterns, which are respectively connected to two sets of connecting parts. The motor rotating shaft is fixedly connected to the threaded rod. The four sets of slides are slidably connected to the two sets of slide bars. The two sets of clamps are symmetrically arranged. The inner side of the clamp is provided with a U-shaped groove that is adapted to the sealing gasket. The welding gap on the rear side of the sealing gasket corresponds to the middle position of the rear positioning component.

[0008] Preferably, the hydraulic cylinder telescopic rod and the bushing are movably connected, the hydraulic cylinder is set in an inclined state, the fixing plate, the circular sleeve, and the limiting plate are integrated into one structure, the circular sleeve is fitted in the middle of the lower set of connecting rods, and the two sets of connecting plates are set on both sides of the sealing gasket gap.

[0009] Preferably, the upper side of the pressure sleeve has a trapezoidal structure, the pressure sleeve is adapted to the sealing gasket, the upper set of the two sets of connecting rods has a notch at the position corresponding to the movable port, the lower set of the two sets of connecting rods is attached to the inner wall of the upper side of the round sleeve, and the wiping assembly is set on the rear set of fixing brackets.

[0010] Preferably, the movable shaft is fixedly connected to the internal gear in the ratchet and movably connected to the housing of the movable shaft. The support plate and the U-shaped spring are inclined. The U-shaped spring and the cleaning block correspond to the gap of the sealing gasket, the notch of the upper connecting rod, and the position of the movable port.

[0011] Preferably, the arc rack and the straight rack are meshed together, the two ends of the torsion spring are respectively inserted into the inner side of the circular ring and the inner wall of the fixed frame, the connecting sleeve is restricted in the movable opening on the circular sleeve, and the straight rack slides against the circular sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The sealing gasket is placed in the grooves of the two sets of clamping plates. The motor drives the threaded rod to rotate, driving the two sets of connecting parts away. The two sets of clamping plates are then moved away through the connection of the sliding table. At this time, the two sets of push blocks will push the inner side of the sealing gasket, pulling apart the joint that needs to be welded, and preventing the gap at the joint of the sealing gasket from being too misaligned. Conversely, the threaded rod is driven to rotate in the opposite direction, which will drive the two sets of clamping plates to come together and clamp the sealing gasket, pushing the gap at the joint of the sealing gasket to be controlled at a certain size. Two sets of positioning components drive hydraulic cylinders, which tilt and push the bushing and connecting plate downwards. The two sets of connecting rods slide downwards along the line between the fixed plate and the limiting plate and along the inner side of the circular sleeve, causing the two sets of pressure sleeves on the upper side to press against the upper side of the sealing gasket. In conjunction with the front positioning components, the sealing gasket is positioned to facilitate welding. At the same time, the pressure sleeve design prevents misalignment of the sealing gasket's head and tail ends, thus effectively aligning the welding ends. After welding, the connecting plate and the two sets of connecting rods are pulled upwards until the lower connecting rod is located on the inner wall of the upper side of the circular sleeve. Continuing to pull upwards causes the lower connecting rod to rotate outwards along the inner wall of the upper side of the circular sleeve. This allows the pressure sleeves to move upwards to release the pressure on the sealing gasket and then rotate outwards to open, facilitating the removal of the sealing gasket and the placement of the next set. As the lower connecting rod moves downwards, it drives the connecting sleeve and linear rack downwards. The linear rack drives the meshing arc rack and the connected ratchet to rotate clockwise. The ratchet generates resistance, driving the entire ratchet and the movable shaft to rotate together. The rotating movable shaft drives the ring to torsion spring, as well as the support plate, U-shaped spring, and cleaning block to rotate, wiping the end faces of the sealing gasket's joint. This removes oil, oxide film, and dust impurities from the end faces, ensuring a clean and flat joint surface. This lays the foundation for subsequent precise jointing and high-quality welding. When the connecting plate moves upwards, it drives the ratchet to rotate counterclockwise. At this time, the ratchet housing rotates, but the inner gear and the movable shaft do not rotate, preventing re-contact with the welded position. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0017] Please see Figures 1-9 One embodiment of the present invention provides a welding and forming processing device for irregularly shaped metal gaskets, including a welding machine 1. A welding gun 2 is fixedly mounted on the upper side of the welding machine 1. An adjustment assembly 3 is fixedly mounted on the upper side of the welding machine 1 near the front of the welding gun 2. Two sets of positioning assemblies 4 are provided on the adjustment assembly 3. The adjustment assembly 3 includes a mounting bracket 31 fixedly mounted on the upper side of the welding machine 1 near the front of the welding gun 2. A threaded rod 32 is movably arranged in the middle of the mounting bracket 31. A motor 3 is fixedly mounted at one end of the mounting bracket 31. 3. The outer thread of the threaded rod 32 is connected to two sets of connectors 34. The upper end of the connectors 34 is fixedly provided with slides 35 at the front and rear positions respectively. The upper end of the mounting bracket 31 is fixedly provided with two sets of slide bars 36. The upper ends of the two sets of slides 35 on both sides are fixedly provided with a set of support plates 37. The two sets of support plates 37 are fixedly provided with clamps 38 at opposite ends on both sides. The upper ends of the two sets of support plates 37 are fixedly provided with push blocks 39 at the rear corner. The inner sides of the two sets of support plates 37 and clamps 38 are provided with sealing gaskets 310.

[0018] The threaded rod 32 has two opposite spiral patterns on its outer side, which are connected to two sets of connectors 34 respectively. The rotating shaft of the motor 33 is fixedly connected to the threaded rod 32. The four sets of slides 35 are slidably connected to the two sets of slide bars 36 respectively. The two sets of clamps 38 are symmetrically arranged. The inner side of the clamps 38 is provided with a U-shaped groove, which is adapted to the sealing gasket 310. The welding gap on the rear side of the sealing gasket 310 corresponds to the middle position of the rear positioning component 4.

[0019] The sealing gasket 310 is placed in the grooves of the two sets of clamping plates 38. The motor 33 drives the threaded rod 32 to rotate, driving the two sets of connecting parts 34 to move away. The two sets of clamping plates 38 are moved away through the connection of the slide table 35. At this time, the two sets of push blocks 39 will push the inner side of the sealing gasket 310, pulling apart the joint that needs to be welded, so as to avoid the gap at the joint of the sealing gasket 310 being too misaligned. In the opposite direction, the threaded rod 32 is driven to rotate, which will drive the two sets of clamping plates 38 to come together and clamp the sealing gasket 310, pushing the gap at the joint of the sealing gasket 310 to control a certain size distance.

[0020] The positioning assembly 4 includes an L-shaped plate 41 fixedly mounted at the rear end of the mounting bracket 31. A fixing bracket 42 is fixedly mounted on the upper end of the L-shaped plate 41. Fixing shafts 43 are fixedly mounted on both sides of the fixing bracket 42. Connecting shafts 44 are sleeved on the outer sides of the two sets of fixing shafts 43. Hydraulic cylinders 45 are fixedly mounted on the lower side of each set of connecting shafts 44. A fixing plate 46 is fixedly mounted at the rear end of the fixing bracket 42. A circular sleeve 47 is fixedly mounted on the lower side of the fixing plate 46. The upper side of the circular sleeve 47 is located on the fixing plate 46. A limiting plate 48 is fixedly installed at the rear position. Movable openings 49 are opened on the inner sides of the fixing plate 46, the round sleeve 47, and the limiting plate 48. Connecting plates 410 are respectively installed on the front and rear sides of the round sleeve 47. A bushing 411 is fixedly installed on the lower front end of the two sets of connecting plates 410. A pressure sleeve 412 is fixedly installed on the upper end of the two sets of connecting plates 410. Two sets of connecting rods 413 are fixedly installed between the two sets of connecting plates 410. A wiping component 414 is installed on the inner side of the fixing frame 42.

[0021] The hydraulic cylinder 45 telescopic rod is movably connected to the bushing 411. The hydraulic cylinder 45 is set in an inclined state. The fixing plate 46, the round sleeve 47, and the limiting plate 48 are integrated into one structure. The round sleeve 47 is fitted in the middle of the lower set of connecting rods 413. The two sets of connecting plates 410 are set on both sides of the gap of the sealing gasket 310. The upper side of the pressure sleeve 412 has a trapezoidal structure. The pressure sleeve 412 is adapted to the sealing gasket 310. The upper set of the two sets of connecting rods 413 has a notch at the position corresponding to the movable port 49. The lower set of the two sets of connecting rods 413 is attached to the upper inner wall of the round sleeve 47. The wiping component 414 is set on the rear set of fixing brackets 42.

[0022] Two sets of positioning components 4 drive hydraulic cylinders 45, which tilt and push the bushing 411 and connecting plate 410 downwards. Meanwhile, two sets of connecting rods 413 slide downwards along the space between the fixed plate 46 and the limiting plate 48, and along the inner side of the circular sleeve 47, causing the two sets of pressure sleeves 412 on the upper side to press against the upper side of the sealing gasket 310. This, in conjunction with the front positioning component 4, achieves the positioning of the sealing gasket 310, facilitating welding. Simultaneously, the positioning design of the pressure sleeves 412 prevents the sealing gasket 310 from being... If the head and tail ends are misaligned vertically or horizontally, the welding ends can be effectively aligned. After welding, the connecting plate 410 and the two sets of connecting rods 413 are pulled upward until the lower connecting rod 413 is located on the upper inner wall of the sleeve 47. Continuing to pull upward will cause the lower connecting rod 413 to rotate outward along the upper inner wall of the sleeve 47. This allows the pressure sleeve 412 to move upward to release the pressure on the sealing gasket 310, and then rotate outward to open, thus facilitating the removal of the sealing gasket 310 and the placement of the next set.

[0023] The wiping assembly 414 includes a movable shaft 4141 movably disposed inside the fixed frame 42. Two sets of rings 4142 are fixedly disposed on the outer side of the movable shaft 4141. A support plate 4143 is fixedly disposed on the upper side of the rings 4142. A U-shaped spring 4144 is fixedly disposed on the upper side of the support plate 4143. Cleaning blocks 4145 are fixedly disposed at both ends of the U-shaped spring 4144. A ratchet 4146 is disposed between the two sets of rings 4142 on the outer side of the movable shaft 4141. An arc rack 4147 is fixedly disposed on the outer shell of the ratchet 4146. Torsion springs 4148 are sleeved on the outer side of the movable shaft 4141 between the two sets of rings 4142 and the inner wall of the fixed frame 42. A connecting sleeve 4149 is sleeved on the lower set of the two sets of connecting rods 413. A straight rack 41410 is fixedly disposed at the front end of the connecting sleeve 4149.

[0024] The movable shaft 4141 is fixedly connected to the internal gear in the ratchet 4146 and is movably connected to the housing of the movable shaft 4141. The support plate 4143 and the U-shaped spring 4144 are inclined. The U-shaped spring 4144 and the cleaning block 4145 correspond to the gap of the sealing gasket 310, the notch of the upper connecting rod 413, and the position of the movable opening 49. The arc rack 4147 and the straight rack 41410 are meshed. The two ends of the torsion spring 4148 are respectively inserted into the inner side of the ring 4142 and the inner wall of the fixed frame 42. The connecting sleeve 4149 is restricted in the movable opening 49 opened on the round sleeve 47. The straight rack 41410 slides against the round sleeve 47.

[0025] As the lower connecting rod 413 moves downward, it drives the connecting sleeve 4149 and the linear rack 41410 to move downward. The linear rack 41410 drives the meshing arc rack 4147 and the connected ratchet 4146 to rotate clockwise. The ratchet 4146 generates resistance, driving the ratchet 4146 and the movable shaft 4141 to rotate together. The rotating movable shaft 4141 drives the ring 4142 to twist the torsion spring 4148, and also drives the support plate 4143 and the U-shaped spring. 4144. The cleaning block 4145 rotates to wipe the end face of the sealing gasket 310 at the joint, which can remove oil, oxide film and dust impurities attached to the end face, ensuring that the joint end face is clean and flat, laying the foundation for subsequent accurate jointing and high-quality welding. When the connecting plate 410 moves upward, it will drive the ratchet 4146 to rotate counterclockwise. At this time, the outer shell of the ratchet 4146 rotates, but the inner gear and the movable shaft 4141 do not rotate, avoiding contact with the welded position again.

[0026] Working principle: In use, the sealing gasket 310 is placed in the grooves of the two sets of clamping plates 38. The motor 33 drives the threaded rod 32 to rotate, driving the two sets of connecting parts 34 to move away. The sliding table 35 connects the two sets of clamping plates 38 to move away. At this time, the two sets of push blocks 39 will push the inner side of the sealing gasket 310, pulling apart the joint that needs to be welded, and preventing the gap at the head and tail of the sealing gasket 310 from being too misaligned. Conversely, the threaded rod 32 is driven to rotate in the opposite direction, which will drive the two sets of clamping plates 38 to move closer and clamp the sealing gasket 310, pushing the gap at the head and tail of the sealing gasket 310 to control a certain distance. Then, the two sets of positioning components 4 drive the hydraulic cylinders 45 respectively. The hydraulic cylinder 45 tilts and pushes the bushing 411 and connecting plate 410 downwards, while the two sets of connecting rods 413 slide downwards along the line between the fixed plate 46 and the limiting plate 48 and the inner side of the round sleeve 47, respectively. This causes the two sets of pressure sleeves 412 on the upper side to press against the upper side of the sealing gasket 310. In conjunction with the front positioning component 4, the sealing gasket 310 is positioned, facilitating welding. At the same time, the positioning design of the pressure sleeves 412 prevents misalignment of the head and tail ends of the sealing gasket 310, thus effectively aligning the welding ends. After welding, the connecting plate 410 and the two sets of connecting rods 413 are pulled upwards until the lower side... After the connecting rod 413 is positioned on the upper inner wall of the sleeve 47, continuous upward pulling will cause the lower connecting rod 413 to rotate outward along the upper inner wall of the sleeve 47. This allows the pressure sleeve 412 to move upward, releasing the pressure on the sealing gasket 310, and then rotating outward to open, facilitating the removal of the sealing gasket 310 and the placement of the next set. During the downward movement of the lower connecting rod 413, the connecting sleeve 4149 and the linear rack 41410 will move downward. The linear rack 41410 drives the meshing arc rack 4147 and the connected ratchet 4146 to rotate clockwise. The ratchet 4146 generates resistance, driving the entire ratchet 4146 to move. The shaft 4141 rotates together with the ring 4142, which in turn drives the torsion spring 4148 to rotate, as well as the support plate 4143, U-shaped spring 4144, and cleaning block 4145 to rotate. This performs end-face wiping work on the joint of the sealing gasket 310, removing oil, oxide film, and dust impurities from the joint surface, ensuring a clean and flat joint surface, and laying the foundation for subsequent precise jointing and high-quality welding. When the connecting plate 410 moves upward, it drives the ratchet 4146 to rotate counterclockwise. At this time, the outer shell of the ratchet 4146 rotates, but the inner gear and the shaft 4141 do not rotate, avoiding re-contact with the welded position.

[0027] The component structures and electrical connections or control methods of the welding machine 1, welding gun 2, motor 33, sealing gasket 310, hydraulic cylinder 45, cleaning block 4145, and ratchet 4146 in this invention are common knowledge in the field. Their working principles are well-known technologies, and the appropriate model is selected according to actual use, so they will not be explained in detail.

[0028] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
