Description

Technical Field

[0001] The present invention relates to the field of metal welding, and particularly to a metal processing and welding device. Background Art

[0002] In the field of metal processing, welding technology is a key process for manufacturing various structures and components. Due to its simple structure, light weight, strong load-bearing capacity, etc., metal round tubes are widely used in many industries. However, during the processing and welding of metal round tubes, there are often some problems, such as the generation of burrs and protrusions, welding deformation, welding defects, and low efficiency.

[0003] Burrs and protrusions are common problems in the processing of metal round tubes. They not only affect the appearance quality, but more importantly, they will interfere with the clamping and welding effect during the welding process. The presence of burrs and protrusions will cause uneven molten pools, poor weld formation, pores, slag inclusions and other defects during the welding process, reducing the welding strength and reliability. In addition, since it is necessary to clean the burrs and protrusions, the workload of preparation before welding is increased, and the welding efficiency is reduced.

[0004] Regarding the metal processing and welding device disclosed in the patent with the publication number "CN116571910B", by designing a semi-circular partition plate on the arc side, during the welding process of two metal round tubes, the welded part can directly push them out through the arc surface of the semi-circular partition plate, so that the semi-circular partition plate is no longer inside the weld, effectively avoiding the situation where the partition plate is stuck inside the weld. However, in general welding work, when welding two different metal round tubes at both ends, burrs and protruding redundant parts are generated, which will cause the staff to perform further grinding after welding the metal round tubes. Therefore, the present application proposes a metal processing and welding device. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a metal processing and welding device.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A metal processing and welding device includes: a metal round tube, a grinding device is sleeved in the middle of the outer side of the metal round tube, clamping rings are sleeved at both ends of the outer side of the metal round tube, a side clamping block is clamped on one side of the bottom end of the clamping ring, a connecting frame is arranged outside the side clamping block at the middle of the upper end of the clamping flat plate, a supporting frame is arranged on the other side of the bottom end of the clamping ring, a receiving card is fixedly arranged at the lower end of the back of the side clamping block in the direction of the lower arc, a corner spring is fixedly arranged at the bottom end of the receiving card in the direction of the lower arc, and an auxiliary structure is fixedly arranged at the bottom end of the corner spring;

[0008] A riser pipe is sleeved outside the auxiliary structure. A compression spring base is arranged at the bottom end of the riser pipe. A bottom plate is welded and arranged at the bottom end of the compression spring base. A plug rail is horizontally slidably arranged at the middle of the top end of the bottom plate. A ground rail is horizontally fixedly arranged at the middle of the plug rail. A clamping flat plate is fixedly arranged at the middle of the outside of the riser pipe. A retaining frame plate is arranged at the front end of the top end of the clamping flat plate. A frame ring is arranged in parallel at the front end of the retaining frame plate. Attachment holes are formed on the surface of the frame ring. A thorn cleaning structure is annularly arranged on the outer side of the front surface of the frame ring.

[0009] Preferably, the grinding device includes a grinding disc, a toothed ring, an attachment gear, a support cylinder and a motor assembly. A toothed ring is arranged at the middle of the outside of the metal round pipe. Tooth saws are annularly arranged outside the toothed ring. A quarter semi-circular grinding disc is fixedly arranged inside the toothed ring. Four attachment gears are arranged outside the toothed ring and the tooth saws. The back of the attachment gear is inserted with a support cylinder. One end of the outside of the support cylinder is in plug connection with the attachment hole formed on the surface of the frame ring. A motor assembly is arranged at one end of the back of the attachment gear on one side of the lower end outside the grinding disc. The motor assembly drives the support cylinder at the back of the attachment gear on one side of the lower end outside the grinding disc to rotate, so that the support cylinder at this position drives the attachment gear to be the power source for driving the toothed ring to rotate.

[0010] Preferably, the front end of the grinding disc bends towards the inside of the toothed ring, and the length of the grinding disc is equal to the width of the toothed ring, so that after the arc part of the front end of the grinding disc contracts towards the inside of the toothed ring, the edge part of the grinding disc will not scratch the surface of the metal round pipe.

[0011] Preferably, the support cylinders at the upper left, upper right and lower right outside the frame ring are fixed to the retaining frame plate and the attachment gears. After the support cylinder at the back of the attachment gear on one side of the lower end outside the grinding disc rotates, it drives the attachment gear at the front end of the support cylinder to rotate, and the attachment gear drives the toothed ring to rotate outside the metal round pipe. It is convenient to clamp the outside of the toothed ring after the support cylinders at the upper left, upper right and lower right outside the frame ring are fixed to the retaining frame plate and the attachment gears, and the support cylinder driven by the motor assembly drives the attachment gear at the back of the attachment gear on one side of the lower end outside the grinding disc to rotate.

[0012] Preferably, the burr cleaning structure includes a first support rod, a second support rod, a roller, a lever, an outer curved rod, a sweeping piece, a front plate, a connecting rod, a first compression spring, a bent rod and a cylinder. A Z-shaped second support rod is fixedly arranged annularly on the front surface of the support ring. A cylinder is arranged at the front end of the second support rod. A first compression spring is clamped inside the cylinder. A bent rod is arranged at the top end of the first compression spring. A Z-shaped lever is fixedly arranged at the bottom of the front end of the bent rod. A connecting rod is fixedly arranged at the front end of the top of the lever. A front plate is arranged at the bottom end of the connecting rod. A sweeping piece is obliquely glued to the back of the bottom end of the front plate. Second support rods are arranged on both sides of the second support rod. A roller is rotatably connected to the front end of the second support rod. An outer curved rod is annularly arranged on the outer side of the roller. The front edge of the outer end of the outer curved rod and the rear edge of the lever are on the same straight line, which is convenient for the outer curved rod to continuously press the edge of the lever after rotation, so that the lever can be lifted up to drive the connecting rod, the front plate and the sweeping piece to lift up.

[0013] Preferably, the output groove of the roller is movably connected to the first support rod. The outer curved rod on the outer side of the roller rotates by rubbing the surface of the metal round tube. The downward pressure of the rotation of the outer curved rod makes the lever lift up, which is convenient for the sweeping piece to stick to the surface of the metal round tube after the front plate is driven by the lever and the connecting rod to lift up.

[0014] Preferably, the auxiliary structure includes a foot frame, a top block, a first inner foot column, a second inner foot column and a second compression spring. Two top blocks of different sizes are arranged at the bottom end of the angle spring. Two second compression springs of different specifications are arranged at the bottom end of the top block. The first inner foot column is arranged at the bottom end of the second compression spring with a larger specification. The first inner foot column is arranged at the bottom end of the second compression spring with a smaller specification. The foot frame is arranged at the bottom ends of the second inner foot column and the first inner foot column. The second inner foot column, the foot frame and the vertical pipe are sleeved and combined, which is convenient for the second inner foot column and the first inner foot column at the top of the foot frame to extend into the vertical pipe and drive the second compression spring and the top block to push the angle spring upward to expand and move to both sides.

[0015] The present invention has the following beneficial effects:

[0016] 1. The support cylinder is clamped through the attachment holes on the outer side of the support ring, and the end of the support cylinder is fixed by the retaining frame plate. The support cylinders and the attachment gears on the upper left, lower left and upper right of the front surface of the support ring fix the toothed ring on the outer side of the metal round tube. The support cylinder at the lower right of the front surface of the support ring is rotated by the motor assembly at the rear end of the support ring. The support cylinder drives the attachment gear at the lower right of the outer side of the toothed ring to rotate. The attachment gear at the lower right corner of the support ring drives the toothed ring to rotate on the outer side of the metal round tube. The grinding piece inside the toothed ring rotates on the outer side of the metal round tube, and the grinding piece grinds the burrs on the surface of the metal round tube.

[0017] 2. When the clamping plate moves forward to clamp the two ends of the metal round tube, the retaining frame plate and the frame ring at the front end of the top of the clamping plate move forward. When the frame ring moves on the outside of the metal round tube, the outer curved rod rolls on the outside of the metal round tube by friction. The outer curved rod presents a U-shaped structure. The roller on the inside of the outer curved rod and the first frame rod form a rotating activity. After the outer curved rod rotates, it continuously squeezes the tail end of the tilting rod, and the tilting rod tilts upward. The connecting rod at the bottom of the front section of the tilting rod drives the front end of the front plate to tilt up. The sweeping piece at the tail end of the front plate is attached to the outside of the metal round tube. When the sweeping piece moves on the outside of the metal round tube, the sweeping piece cleans the dust on the surface of the metal round tube.

[0018] 3. When the metal round tube is inserted into the interior of the side clamp block, the two sides of the metal round tube squeeze one side of the side clamp block. After the side clamp block is subjected to force, the receiving card moves to both sides. At the same time, the metal round tube as a whole applies pressure to the receiving card, and the receiving card drives the angle spring to twist inward. The angle spring squeezes the top block to move downward, and the second compression spring at the bottom of the top block contracts under force. The second built-in foot column at the bottom of the second compression spring and the first built-in foot column provide support. At the same time, the foot frame at the bottom of the first built-in foot column and the second built-in foot column is stuck at the upper end of the outer side of the compression spring base. At this time, the auxiliary structure is placed inside the riser as a whole. The auxiliary structure helps the side clamp block to expand after the outside of the metal round tube is extended in. The side clamp block is fitted after the metal round tube is put in. The two sides of the clamp ring prevent the side clamp block from expanding excessively. In this way, the fitting degree between the metal round tube and the side clamp block and the clamp ring will be improved, preventing the metal round tube from shifting and shaking during welding.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1:

[0030] Referring to Figure 1 - Figure 2 , a metal processing and welding device includes: a metal round tube 11, a grinding device is sleeved in the middle of the outer side of the metal round tube 11, clamping rings 20 are sleeved at both ends of the outer side of the metal round tube 11, a side clamping block 21 is clamped on one side of the bottom end of the clamping ring 20, a connecting frame 12 is arranged outside the side clamping block 21 in the middle of the upper end of the clamping flat plate 1, a support frame 10 is arranged on the other side of the bottom end of the clamping ring 20, a receiving card 6 is fixedly arranged at the lower end of the back surface of the side clamping block 21 in the downward arc direction, an angle spring 9 is fixedly arranged at the bottom end of the receiving card 6 in the downward arc direction, and an auxiliary structure 24 is fixedly arranged at the bottom end of the angle spring 9;

[0031] A vertical pipe 5 is sleeved outside the auxiliary structure 24, a spring base 25 is arranged at the bottom end of the vertical pipe 5, a bottom plate 2 is welded at the bottom end of the spring base 25, an insertion rail 3 is horizontally slidably arranged at the middle of the top end of the bottom plate 2, a ground rail 4 is horizontally fixedly arranged at the middle of the insertion rail 3, a clamping flat plate 1 is fixedly arranged at the middle of the outer side of the vertical pipe 5, a fixing frame plate 18 is arranged at the front end of the top end of the clamping flat plate 1, a frame ring 19 is arranged in parallel at the front end of the fixing frame plate 18, an attached hole 23 is formed on the surface of the frame ring 19, and a burr cleaning structure 17 is annularly arranged outside the front surface of the frame ring 19;

[0032] The metal round tube 11 is placed between the side clamping blocks 21 and the clamping ring 20. After the receiving card 6 inside the side clamping block 21 is stressed, it moves towards the lower left side and the lower right side. After the angle spring 9 is stressed, it compresses and twists. The clamping ring 20 at the top of the side clamping block 21 restricts the excessive expansion of the side clamping block 21 to fit the outer side of the metal round tube 11. The angle spring 9 presses against the top block 242, and the top block 242 is stressed to press the second compression spring 245 downward. The first built-in foot post 243 and the second built-in foot post 244 at the bottom end of the second compression spring 245 provide a supporting force, so that the compression degree of the second compression spring 245 is restricted. After the compression degree of the second compression spring 245 is restricted, the descending degree of the top block 242 is reduced, and the top block 242 prevents the angle spring 9 from sinking excessively. The user activates the electric telescopic machine body 8, and the electric telescopic machine body 8 drives the push block 7 to perform telescopic movement. The push block 7 drives the clamping flat plate 1 to move. Since the vertical pipe 5 is clamped inside the clamping flat plate 1, the foot frame 241 at the bottom end of the vertical pipe 5 is engaged with the compression spring base 25 at the top end of the bottom plate 2. When the vertical pipe 5 moves, it drives the foot frame 241 and the compression spring base 25 to move. The compression spring base 25 drives the bottom plate 2 to move, and the bottom plate 2 moves inside the insertion rails 3 on both sides of the ground rail 4. At this time, the side clamping blocks 21 and the clamping ring 20 will move back and forth on the outer side of the metal round tube 11.

[0033] In this embodiment, in the embodiment of the present invention, the metal round tube 11 is placed between the side clamping blocks 21 and the clamping ring 20. The side clamping blocks 21 and the clamping ring 20 together form a clamping mechanism for fixing the metal round tube 11. After the metal round tube 11 is placed in the clamping mechanism, the receiving card 6 inside the side clamping block 21 is stressed and moves towards the lower left side and the lower right side. After the angle spring 9 is stressed, it compresses and twists. The clamping ring 20 at the top of the side clamping block 21 restricts the excessive expansion of the side clamping block 21 to fit the outer side of the metal round tube 11. This clamping mechanism can effectively fix the metal round tube 11 and prevent it from moving or deforming during the welding process.

[0034] In the embodiment of the present invention, a vertical pipe 5 is sleeved outside the auxiliary structure 24. A compression spring base 25 is provided at the bottom end of the vertical pipe 5. A bottom plate 2 is welded at the bottom end of the compression spring base 25. An insertion rail 3 is horizontally slidably arranged in the middle of the top end of the bottom plate 2. A ground rail 4 is horizontally fixed in the middle of the insertion rail 3. A clamping flat plate 1 is fixedly arranged in the middle of the outside of the vertical pipe 5. A retaining frame plate 18 is arranged at the front end of the top end of the clamping flat plate 1. A frame ring 19 is arranged in parallel at the front end of the retaining frame plate 18. Attachment holes 23 are formed on the surface of the frame ring 19. A burr cleaning structure 17 is annularly arranged on the outside of the front surface of the frame ring 19;

[0035] The user activates the electric telescopic machine body 8, and the electric telescopic machine body 8 drives the push block 7 to perform telescopic activities. The push block 7 drives the clamping flat plate 1 to move. Since the vertical pipe 5 is clamped inside the clamping flat plate 1, the foot frame 241 at the bottom end of the vertical pipe 5 is engaged with the spring pressing base 25 at the top end of the bottom plate 2. When the vertical pipe 5 moves, it drives the foot frame 241 and the spring pressing base 25 to move, and the spring pressing base 25 drives the bottom plate 2 to move. The bottom plate 2 moves inside the insertion rails 3 on both sides of the ground rail 4. At this time, the side clamping blocks 21 and the clamping rings 20 will move back and forth on the outer side of the metal round pipe 11;

[0036] In the embodiment of the present invention, by driving the push block 7 to perform telescopic activities through the electric telescopic machine body 8, the movement control of the clamping flat plate 1 can be realized, so as to realize the clamping and loosening of the metal round pipe 11. This structure can facilitate the installation and disassembly of the metal round pipe 11 and improve work efficiency.

[0037] Embodiment 2:

[0038] Different from Embodiment 1, referring to Figure 1 、 Figure 2 and Figure 3 , this embodiment also has the following further content:

[0039] The grinding device includes a grinding disc 13, a toothed ring 14, an attached gear 15, a support cylinder 16 and a motor assembly 22. A toothed ring 14 is arranged in the middle of the outer side of the metal round pipe 11. Tooth saws are annularly arranged on the outer side of the toothed ring 14. A quarter semi-circular grinding disc 13 is fixedly arranged on the inner side of the toothed ring 14. Four attached gears 15 are arranged on the outer side of the tooth saws of the toothed ring 14. The back of the attached gear 15 is inserted with a support cylinder 16. One end of the outer side of the support cylinder 16 is in plug connection with the attachment hole 23 opened on the surface of the frame ring 19. A motor assembly 22 is arranged at one end of the back of the attached gear 15 on the lower side of the outer side of the grinding disc 13, and the motor assembly 22 drives the support cylinder 16 on the back of the attached gear 15 on the lower side of the outer side of the grinding disc 13 to rotate.

[0040] When the clamping plate 1 moves, it drives the fixed frame plate 18 and the frame ring 19 to move. The fixed frame plate 18 fixes the support tubes 16 passing through the upper left, lower left and upper right of the front of the frame ring 19. The support tube 16 passing through the lower right corner of the front of the frame ring 19 is driven by the motor assembly 22 to rotate. At this time, the support tube 16 at the lower right corner of the front of the frame ring 19 drives the attached gear 15 at the lower right corner of the outer side of the gear ring 14 to rotate, and the other three attached gears 15 restrict the gear ring 14 to the outside of the metal round tube 11. At the same time, the attached gears 15 at the other three positions 5 can rotate along with the rotation of the gear ring 14 on the outside of the front end of the other support tubes 16. As the attached gear 15 at the lower right corner of the outer side of the gear ring 14 rotates, when the gear ring 14 rotates, the grinding disc 13 inside the gear ring 14 rotates and grinds on the outer side of the metal round tube 11, and the front end of the grinding disc 13 curls toward the inner side of the gear ring 14, so that the part where the grinding disc 13 contacts the surface of the metal round tube 11 presents an arc structure, so as to prevent the edge of the grinding disc 13 from being too sharp and damaging the surface of the metal round tube 11.

[0041] In this embodiment, the motor assembly 22 drives the support tube 16 to rotate, and then drives the attached gear 15 and the gear ring 14 to rotate, so that the grinding disc 13 grinds the surface of the metal round tube 11. The structural design of the front end of the grinding disc 13 curling toward the inner side of the gear ring 14 can prevent the edge of the grinding disc 13 from being too sharp and damaging the surface of the metal round tube 11, thereby improving the grinding effect.

[0042] Embodiment three:

[0043] Reference Figure 5 - Figure 6 , compared with the first embodiment and the second embodiment, in this embodiment:

[0044] The thorn cleaning structure 17 includes a first frame rod 171, a second frame rod 172, a roller 173, a tilting rod 174, an outer curved rod 175, a sweeping piece 176, a front plate 177, a connecting rod 178, a first compression spring 179, a curved rod 1710 and a cylinder 1711. The front of the frame ring 19 is annularly fixed with a Z-shaped second frame rod 172, a cylinder 1711 is provided at the front end of the second frame rod 172, and a first compression spring 179 is provided on the inner side of the cylinder 1711. The top of the first compression spring 179 is provided with a curved rod 1710, and the curved rod 1711 is provided with a curved rod 1710. A Z-shaped tilting rod 174 is fixedly provided at the bottom of the front end of 710, a connecting rod 178 is fixedly provided at the front end of the top of the tilting rod 174, a front plate 177 is provided at the bottom end of the connecting rod 178, a sweeping piece 176 is obliquely glued to the back side of the bottom end of the front plate 177, second racks 172 are provided on both sides of the second rack 172, a roller 173 is rotatably connected to the front end of the second rack 172, an outer curved rod 175 is provided in a ring shape on the outer side of the roller 173, and the front end edge of the outer curved rod 175 is on the same straight line as the rear end edge of the tilting rod 174.

[0045] The frame ring 19 moves along with the clamping plate 1 on the outside of the metal round tube 11, and the second frame rod 172 and the first frame rod 171 at the middle of the front end of the frame ring 19 move along with the frame ring 19, and the bottom of the front end of the second frame rod 172 applies a force to the roller 173 to roll forward, and at this time, the roller 173 starts to roll, and the outer curved rod 175 outside the roller 173 starts to rotate, and the outer curved rod 175 presents a U-shaped structure, and the protruding part of the outer curved rod 175 continuously presses the tilting rod 174, and the tilting rod 17 4 begins to tilt upward, the connecting rod 178 at the bottom end of the front end of the tilting rod 174 drives the front plate 177 to tilt up, and the sweeping piece 176 at the rear end of the front plate 177 sticks to the surface of the metal round tube 11, so that the front plate 177 is constantly tilted up, and the sweeping piece 176 at the rear end of the front plate 177 is constantly in contact with the surface of the metal round tube 11. As the frame ring 19 moves back and forth, the sweeping piece 176 also moves continuously on the surface of the metal round tube 11, and the sweeping piece 176 can clean the dust on the surface of the metal round tube 11.

[0046] In this embodiment, when the frame ring 19 moves with the clamping plate 1, the second frame rod 172 and the first frame rod 171 follow the movement, and the roller 173 starts to roll due to the rolling force toward the front side, driving the outer curved rod 175 to rotate. The protruding part of the outer curved rod 175 presses the tilting rod 174 to tilt it upward, thereby driving the connecting rod 178 and the front plate 177 to tilt. The sweeping piece 176 at the rear end of the front plate 177 is in close contact with the surface of the metal round tube 11. As the frame ring 19 moves back and forth, the sweeping piece 176 moves on the surface of the metal round tube 11 to effectively clean the dust. This structural design ensures the continuity and effectiveness of cleaning, while protecting the surface of the metal round tube 11 from damage.

[0047] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
