Description

Technical Field

[0001] The present invention relates to the technical field of steel plate welding, and specifically relates to a straight seam welding machine for steel plate processing. Background Art

[0002] In the manufacturing industry of steel plate processing, the straight seam welding technology is an extremely crucial and widely applied process. With the continuous progress of industrial technology and the increasingly diverse market demands, the steel plate straight seam welding technology has also made great progress. In the steel plate processing industry, the straight seam welding machine, as a key technical equipment, plays a vital role. With the continuous progress of technology and the increasing demand for industrial production, the technology of the steel plate straight seam welding machine has also developed significantly.

[0003] In the existing technology of straight seam welding machines for steel plate processing, there are many deficiencies. First of all, during the welding process of traditional welding machines, when the steel plate is subjected to the vibration effect applied during existing vibration welding, the vibration force will be transmitted along with the steel plate, and the welded part of the steel plate will also be continuously affected by vibration when the welding head welds a new part, resulting in uneven stress distribution and increasing the risk of weld cracking. Secondly, traditional welding machines cannot apply an appropriate vibration force to the steel plate during the welding process, and the vibration effect is always applied to the steel plate by means of transmission, which will cause the solder joints farther away from the application position to not receive a good welding effect, and it is impossible to make any welding position receive the same vibration effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this solution, by setting a consolidation component and using the gap between two fixed pressing plates as the welding opening, it ensures that the laser welding head can accurately align with the weld position. The connecting plate, insertion sheath, and limiting plate above the fixed pressing plate cooperate with the side insertion block of the laser welding head, achieving a tight connection between the welding component and the consolidation component. During the welding process, four weight blocks apply additional load to the welding area of the steel plate, effectively preventing the deformation or movement of the steel plate due to welding heat or external forces. At the same time, the setting of the buffer layer can absorb the excess vibration generated during welding, ensuring that the vibration effect is concentrated on the welding position, avoiding negative impacts on other welded parts of the steel plate, improving the welding stability, making the vibration effect more concentrated on the current welding position, avoiding the destruction of the microscopic structure of the weld by the transmitted vibration in the already welded parts, and reducing the generation of negative impacts such as cracks;

[0018] 2. In this solution, by setting a vibration component, the small motor drives the engagement of the small threaded rod with the engagement block of the sliding convex strip, achieving the precise movement of the sliding convex strip on the bottom surface of the lifting plate body. This movement mode is synchronized with the movement of the welding component, ensuring that the vibration source is always below the welding position, providing a continuous and uniform vibration effect for the weld. The vibration not only promotes the convection and disturbance of the liquid in the molten pool, contributing to the floating and escape of gas and impurities, reducing porosity and slag inclusions inside the weld; at the same time, it also promotes the plastic deformation of the weld metal at high temperature, adjusts the distribution of residual stress, reduces the stress concentration degree, and significantly improves the crack resistance of the weld;

[0019] 3. In this solution, by setting a preheating component, after the bearing component rises, if the trigger button is not triggered, the data processor determines that the steel plate is too thick and immediately starts the preheating component. The exhaust fan inside the heating tube body sucks in external air, which is heated by the electric heater to form hot air and blows towards the surface of the steel plate through the connecting air duct and the outlet air duct, achieving uniform preheating of the steel plate. The preheating treatment not only increases the temperature of the steel plate, making it easier to form a molten pool during welding, but also reduces the generation of welding stress and cracks. After welding, the control motor drives the engagement of the engagement tooth cylinder with the engagement tooth groove, causing the outlet air duct and the connecting air duct to rotate downward. The exhaust fan sucks in air again and blows air through the outlet air duct to cool the welded steel plate finished product, gradually reducing the temperature of the steel plate, avoiding thermal stress or deformation problems caused by rapid cooling.

[0034] A bottom frame body 1, one side of the bottom frame body 1 is provided with a top frame body 2 through a column. A groove facing inward is provided at the center of the top frame body 2, and the groove penetrates the upper and lower surfaces of the top frame body 2. A control panel 10 is provided on one side surface of the top frame body 2. A welding assembly is provided on the upper surface of the top frame body 2. A fixed top pipe 5 is provided on the upper surface of the top frame body 2. An L-shaped connecting rod 4 is provided above the fixed top pipe 5. One end bottom surface of the connecting rod 4 is provided with a telescopic motor 24. The bottom surface of the telescopic motor 24 is provided with a lower support rod 22. One end of the lower support rod 22 is provided with a light detection head 23. The bottom surface of the connecting rod 4 is provided with a roller 27. The roller 27 is used to assist the welding assembly to slide above the top frame body 2. A driving motor 6 is provided on one side surface of the fixed top pipe 5. A meshing threaded rod 7 is provided on the output end of the driving motor 6. One end of the connecting rod 4 is also provided with a data processor 30. There is an electrical connection between the data processor 30 and the control panel 10. A meshing plate 29 that cooperates with the meshing threaded rod 7 is provided on one side surface of the data processor 30. The bottom surface of the connecting rod 4 is provided with an L-shaped fixing plate body 25. An inverted L-shaped sliding frame body 28 is provided on the upper surface of the fixing plate body 25. A pushing motor 26 is fixedly provided on the side surface of the fixing plate body 25. The output end of the pushing motor 26 is connected to one side surface of the sliding frame body 28. Two side plates are provided on the side surface of the sliding frame body 28. The upper one is a fixed side plate, and the lower one is a sliding side plate. A driving hydraulic rod is provided on the upper surface of the fixed side plate. The output end of the driving hydraulic rod penetrates the center of the fixed side plate and is connected to the upper surface of the sliding side plate. A laser welding head 31 and a side insertion block 32 are provided on the bottom surface of the sliding side plate;

[0035] In use, in the case of welding required, after the staff places the steel plate original piece to be welded above the bearing component, the driving motor 6 is started by the signal control of the staff. When the driving motor 6 starts, the meshing threaded rod 7 rotates accordingly, and through the meshing effect of the meshing threaded rod 7 and the meshing plate 29, the data processor 30 drives the fixed plate body 25 to move above the fixed top pipe 5 and stops after reaching one end of the fixed top pipe 5. Subsequently, the pushing motor 26 is driven according to the signal to push the sliding frame body 28 to one side. Then, the laser welding head 31 descends under the action of the hydraulic rod arranged above it and is connected to the pressing and fixing component through the side insertion block 32 on its side. At this time, the preparation process is completed. Subsequently, the staff can use the laser welding head 31 to perform the welding process on the steel plate original piece. The driving motor 6 then rotates in the reverse direction to drive the laser welding head 31 to move on the surface of the steel plate and complete the welding work. The auxiliary mechanism is synchronously started during the welding work and plays a role in improving the welding effect.

[0036] An auxiliary mechanism is arranged at the center of the top frame body 2. The auxiliary mechanism includes a bearing component and a pressing and fixing component. The pressing and fixing component includes two fixed pressing plates 3. The two fixed pressing plates 3 are fixedly connected to the side walls of the adjacent grooves. The gap between the two fixed pressing plates 3 is the welding opening. A weight component is slidably connected to the upper surfaces of the two fixed pressing plates 3. The weight component includes a connecting plate 17. A bottom bracket 18 is arranged on the bottom surface of the connecting plate 17. Four weight blocks 19 are arranged on the bottom surface of the bottom bracket 18. A buffer layer 20 is arranged on the bottom surface of the weight block 19. An insulating board 21 is arranged on the bottom surface of the buffer layer 20. The insulating board 21 is attached to the upper surfaces of the two fixed pressing plates 3. An insertion sheath 16 is arranged on the upper surface of the connecting plate 17. A limiting plate body 9 is arranged on the upper surface of the insertion sheath 16. A side insertion block 32 matching the insertion sheath 16 is arranged on one side surface of the sliding frame body 28;

[0037] When the pressing and fixing component is performing welding work, it is used to apply an additional fixing effect to the surface of the steel plate. During the preparation stage of the welding work, when the welding component is moving, the side insertion block 32 stops after contacting the limiting plate body 9. Subsequently, when the laser welding head 31 descends, the side insertion block 32 on its side surface will insert into the inside of the insertion sheath 16 from above. At this time, the laser welding head 31 is located at the center of the four weighting blocks 19. When the welding work starts, during the movement of the welding component, due to the combined effect of the insertion sheath 16 and the side insertion block 32, the pressing and fixing component will drive the bottom bracket 18 to slide inside the fixed pressing plate 3 following the movement of the welding component, so that the laser welding head 31 is always located at the center of the four weighting blocks 19 for welding work. During the welding process, the four weighting blocks 19 will apply additional load to the welding position area of the steel plate, and the buffer layer 20 will absorb the excess vibration, making the vibration effect generated by the vibrating component more concentrated on the current welding position and not conducted to other parts of the steel plate, avoiding negative impacts such as the welded parts that have been completed being damaged due to excessive conductive vibration, resulting in a reduction in weld strength and the generation of cracks.

[0038] The bearing component includes a plate body part and a vibrating part. The plate body part includes: a bottom fixing column 11, which is fixedly installed on the upper surface of the bottom frame body 1. An electric telescopic rod 33 is arranged on the upper surface of the bottom fixing column 11. The end of the output shaft of the electric telescopic rod 33 is provided with a lifting plate body 13. A limiting block 34 for limiting the lifting plate body 13 is arranged on one side surface of the top frame body 2. A lifting plate body 12 is arranged on one side surface of the lifting plate body 13. A side sliding block 37 is arranged on one side surface of the lifting plate body 12. A slideway matching with the side sliding block 37 is opened on the inner side surface of the bottom frame body 1. A bearing plate body 36 is arranged at the center of the lifting plate body 12;

[0039] The plate body part is used to place the steel plate original before the welding work starts. Before the welding work starts, the staff places the steel plate original above the bearing plate body 36. Subsequently, during the welding work, the electric telescopic rod 33 is driven to start through the staff's signal, and the lifting plate body 13 is driven to rise, and the lifting plate body 12 is driven to rise synchronously. The side sliding block 37 on the side surface of the lifting plate body 12 slides inside the slideway. As the lifting plate body 13 rises, the lifting plate body 12 finally fits against the bottom surface of the top frame body 2. Subsequently, the welding work can be carried out. If the lifting plate body 12 fails to successfully fit against the bottom surface of the top frame body 2, it can be judged that the steel plate is too thick. Then the preheating component is immediately started to preheat the steel plate original. After the preheating work is completed, the welding work can be normally completed.

[0040] The vibrating component includes: a sliding rib 35, the sliding rib 35 is located below the bearing plate body 36, a bottom bump 45 matching with the sliding rib 35 is arranged on the bottom surface of the bearing plate body 36, force-bearing side plates 43 are arranged on both side surfaces of the bottom bump 45, a plate body side groove 46 matching with the force-bearing side plates 43 is formed on the inner side surface of the lifting plate body 12, force-bearing springs 44 are arranged between the upper and lower surfaces inside the plate body side groove 46 and the surfaces of the force-bearing side plates 43, a hidden groove is formed on one side surface of the lifting plate body 13, a small motor 39 is arranged inside the hidden groove, a small threaded rod 42 is arranged on the output end of the small motor 39, an engaging block 38 matching with the small threaded rod 42 is arranged on the bottom surface of the sliding rib 35, sliding side frames 41 are arranged on both side surfaces of the sliding rib 35, sliding grooves 47 matching with the sliding side frames 41 are formed on both sides of the bottom surface of the lifting plate body 12, a positioning light lamp 40 is further arranged on the bottom surface of the sliding rib 35, and a light detection head 23 matching with the positioning light lamp 40 is further arranged on the bottom side surface of the lower support rod 22;

[0041] During the welding process, a certain vibration force is applied to the steel plate original component by the vibration component. The vibration effect can promote the convection and disturbance of the liquid in the molten pool, making it easier for gases and impurities to float to the surface of the molten pool, and then escape or be removed, thereby reducing porosity and slag inclusions inside the weld. It can also promote the plastic deformation of the weld metal at high temperatures, thereby adjusting the distribution of residual stress, reducing the stress concentration degree, and improving the crack resistance of the weld. Before the welding work starts, when the welding assembly reaches one side of the fixed pipe jack 5 and completes the connection with the pressing and fixing component, the telescopic motor 24 at one end of the connecting rod 4 starts following the signal from the staff and drives the lower support rod 22 to descend. When the light detection head 23 at the end of the lower support rod 22 is parallel to the positioning light 40, the laser emitted by the positioning light 40 will be received by the light detection head 23, and the lower support rod 22 will stop driving and transmit the signal to the data processor 30. Subsequently, the small motor 39 is driven after receiving the driving signal sent by the data processor 30. Through the meshing effect of the small threaded rod 42 and the meshing block 38, the sliding convex strip 35 moves on the bottom surface of the lifting plate body 12. During the movement, the positioning light 40 and the light detection head 23 always maintain an induction state to ensure that the moving speed of the sliding convex strip 35 is the same as that of the welding assembly. The sliding side frame 41 on the side surface of the sliding convex strip 35 slides inside the sliding groove 47 to ensure the stability of the sliding convex strip 35. When the sliding convex strip 35 moves, it contacts the bottom convex block 45 on the bottom surface of the bearing plate body 36 and pushes the bottom convex block 45 upward, causing the bearing plate body 36 to slightly shake up and down through the stress spring 44 on the side surface. Since the vibration component moves along with the welding assembly and the vibration source is always located below the welding position, the welding position always maintains the best vibration effect. Under the action of the pressing and fixing component, it prevents the over-strong vibration effect from being transmitted to other parts of the steel plate and causing damage to the already welded parts.

[0042] The auxiliary mechanism further includes a preheating component, and the preheating component includes: two heating pipe bodies 8, both of the two heating pipe bodies 8 are arranged on one side surface of the top frame body 2, a suction fan 48 is arranged inside the heating pipe body 8, a storage battery 49 is arranged on one side surface of the heating pipe body 8, a plurality of electric heaters 50 are arranged inside the heating pipe body 8, a rotating collar 51 is arranged on one side surface of the heating pipe body 8, a top plate body 55 is arranged on one side surface of the rotating collar 51 away from the heating pipe body 8, a plurality of air outlet pipes 52 are arranged on the bottom surface of the top plate body 55, a connecting air pipe 53 is arranged between every two air outlet pipes 52, air outlet channels are arranged on both the upper and lower sides of the connecting air pipe 53, a meshing tooth groove 54 is arranged at the center of the top plate body 55, a meshing tooth cylinder 57 is arranged on the upper surface of the meshing tooth groove 54, a control motor 56 is arranged on one side surface of the meshing tooth cylinder 57, the control motor 56 is arranged inside the top frame body 2, a temperature detector 14 and a trigger button 15 are further arranged on the bottom surface of the top frame body 2, and there is an electrical connection between the trigger button 15 and the data processor 30;

[0043] The preheating component is used to start when the steel plate is too thick. After the bearing component rises and the trigger button 15 on the bottom surface of the top frame 2 is not triggered, when the data processor 30 does not receive the signal of the trigger button 15, it can be judged that the original steel plate is too thick. At this time, the exhaust fan 48 inside the heating tube 8 is driven by the signal of the data processor 30 to start, sucking in external air. The electric heater 50 inside the heating tube 8 also starts heating immediately, heating the air sucked in by the exhaust fan 48. The hot air enters the interior of the connecting air duct 53 after passing through the heating tube 8 and is blown out through the openings of the plurality of air outlet ducts 52 and enters through the gap formed by the lifting plate body 12 not contacting the bottom surface of the top frame 2 and contacts the original steel plate, preheating the original steel plate. The air outlet ducts 52 on the side surfaces of the two heating tubes 8 are arranged in a staggered state. When the hot air is blown out from one side of the air outlet duct 52, it exits through the air outlet ducts on the upper and lower sides of the other connecting air duct 53. The temperature detector 14 always contacts the surface of the original steel plate and senses the temperature of the original steel plate in real time. When the specified temperature is reached, the preheating component stops driving. At this time, welding work can be carried out. After the electric heater 50 inside the heating tube 8 stops starting, the temperature inside the heating tube 8 gradually decreases. After the welding work is completed, the bearing component descends and resets. The control motor 56 inside the top frame 2 drives the meshing gear cylinder 57. Through the meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54, the air outlet duct 52 and the connecting air duct 53 rotate through the rotating collar 51 at the connection with the heating tube 8. Through the rotating collar 51, it can be ensured that when the air outlet duct 52 and the connecting air duct 53 rotate, it will not affect the entry of hot air inside the heating tube 8. Through the meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54, the air outlet duct 52 and the connecting air duct 53 rotate downward by 45 degrees to adjust the blowing angle. At this time, the exhaust fan 48 sucks in air again and blows air through the air outlet duct 52 to cool the welded steel plate finished product. As the temperature inside the heating tube 8 gradually decreases, the temperature of the blown air also gradually decreases, which can gradually cool the steel plate finished product.

[0044] The working principle of the present invention is:

[0045] During use, in the case of welding required, after the staff place the steel plate original parts to be welded above the bearing assembly, they start the drive motor 6 through signal control by the staff. When the drive motor 6 starts, the meshing threaded rod 7 rotates accordingly, and through the meshing effect between the meshing threaded rod 7 and the meshing plate 29, the data processor 30 drives the fixed plate body 25 to move above the fixed top pipe 5 and stops after reaching one end of the fixed top pipe 5. Subsequently, the push motor 26 is driven according to the signal to push the sliding frame body 28 to one side. Then, the laser welding head 31 descends under the action of the hydraulic rod arranged above it and is connected to the pressing and fixing assembly through the side insertion block 32 on its side. At this time, the preparation process is completed. Subsequently, the staff can use the laser welding head 31 to perform the welding process on the steel plate original parts. The drive motor 6 then rotates in the reverse direction, driving the laser welding head 31 to move on the surface of the steel plate and complete the welding work. The auxiliary mechanism starts synchronously during the welding work and plays a role in improving the welding effect;

[0046] During the welding work, the pressing and fixing assembly is used to apply an additional fixing effect on the surface of the steel plate. During the preparation stage of the welding work, when the welding assembly is moving, the side insertion block 32 stops after contacting the limiting plate body 9. Subsequently, when the laser welding head 31 descends, the side insertion block 32 on its side surface will insert into the inside of the insertion sheath 16 from above. At this time, the laser welding head 31 is located at the center of the four weighting blocks 19. When the welding work starts, during the movement of the welding assembly, the pressing and fixing assembly drives the bottom bracket 18 to slide and follow inside the fixed pressing plate 3 with the movement of the welding assembly through the combination effect of the insertion sheath 16 and the side insertion block 32, so that the laser welding head 31 is always located at the center of the four weighting blocks 19 for welding work. During the welding process, the four weighting blocks 19 apply additional load to the welding position area of the steel plate, and the buffer layer 20 absorbs the excess vibration, making the vibration effect generated by the vibrating components more concentrated on the current welding position and not being transmitted to other parts of the steel plate;

[0047] The plate body component is used to place the steel plate original before the welding work starts. Before the welding work begins, the staff places the steel plate original above the bearing plate body 36. Subsequently, when the welding work is carried out, the electric telescopic rod 33 is driven to start by the staff's signal, and drives the lifting plate body 13 to rise, and drives the lifting plate body 12 to rise synchronously. The side slider 37 on the side surface of the lifting plate body 12 slides inside the slideway. As the lifting plate body 13 rises, the lifting plate body 12 finally fits with the bottom surface of the top frame body 2. Subsequently, the welding work can be carried out. If the lifting plate body 12 fails to successfully fit with the bottom surface of the top frame body 2, it can be judged that the steel plate is too thick. Then the preheating component is started immediately to preheat the steel plate original. After the preheating work is completed, the welding work can be normally completed;

[0048] During the welding work, the vibration component applies a certain vibration force to the steel plate original. Before the welding work starts, when the welding component reaches one side of the fixed pipe 5 and completes the connection with the pressing component, the telescopic motor 24 at one end of the connecting rod 4 starts following the staff's signal and drives the lower support rod 22 to descend. When the light detection head 23 at the end of the lower support rod 22 is parallel to the positioning light lamp 40, the laser emitted by the positioning light lamp 40 will be received by the light detection head 23. Then the lower support rod 22 stops driving and transmits the signal to the data processor 30. Subsequently, the small motor 39 is driven after receiving the driving signal sent by the data processor 30. Through the meshing effect of the small threaded rod 42 and the meshing block 38, the sliding convex strip 35 moves on the bottom surface of the lifting plate body 12. During the movement, the positioning light lamp 40 and the light detection head 23 always maintain an induction state, so as to ensure that the moving speed of the sliding convex strip 35 is the same as that of the welding component. The sliding side frame 41 on the side surface of the sliding convex strip 35 slides inside the sliding groove 47 to ensure the stability of the sliding convex strip 35. When the sliding convex strip 35 moves, it contacts the bottom convex block 45 on the bottom surface of the bearing plate body 36 and pushes the bottom convex block 45 upward, causing the bearing plate body 36 to shake slightly up and down through the stress spring 44 on the side surface. Because the vibration component moves along with the welding component and the vibration source is always located below the welding position, the best vibration effect is always maintained at the welding position. And under the action of the pressing component, it prevents the too strong vibration effect from being transmitted to other parts of the steel plate and causing damage to the already welded parts;

[0049] The preheating component is used to start when the steel plate is too thick. After the bearing component rises, when the trigger button 15 on the bottom surface of the top frame 2 is not triggered and the data processor 30 does not receive the signal of the trigger button 15, it can be judged that the steel plate original is too thick. At this time, the exhaust fan 48 inside the heating tube 8 is driven by the signal of the data processor 30 to start, sucking in external air. The electric heater 50 inside the heating tube 8 also starts heating immediately, heating the air sucked in by the exhaust fan 48. The hot air enters the inside of the connecting air duct 53 after passing through the heating tube 8, and is blown out from the openings of the plurality of air outlet pipes 52 and enters through the gap generated by the non-contact between the lifting plate body 12 and the bottom surface of the top frame 2, and contacts the steel plate original to preheat the steel plate original. The temperature detector 14 always contacts the surface of the steel plate original and senses the temperature of the steel plate original in real time. When the specified temperature is reached, the preheating component stops driving. At this time, welding work can be carried out. After the electric heater 50 inside the heating tube 8 stops starting, the temperature inside the heating tube 8 gradually decreases. After the welding work is completed, the bearing component descends and resets. The control motor 56 inside the top frame 2 drives the meshing gear cylinder 57. Through the meshing effect of the meshing gear cylinder 57 and the meshing tooth groove 54, the air outlet pipe 52 and the connecting air duct 53 rotate downward by 45 degrees. At this time, the exhaust fan 48 sucks in air again and blows air through the air outlet pipe 52 to cool the welded steel plate finished product.
