Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a double-sided laser composite welding device. Background Art

[0002] Welding is a process that uses heating or pressurization to achieve atomic bonding of welded parts and form permanent joints, while double-sided welding refers to the process of performing two welding operations on a workpiece, one up and one down. It is widely used on metal plates because it can significantly improve the strength and stability of the connection. Under normal circumstances, when the thickness of the metal plate exceeds 3mm, directly welding it may result in poor weld quality, so it is usually necessary to open a bevel for welding to increase the welding area and improve the welding strength. However, the existing equipment requires additional equipment for cutting when performing double-sided welding, and after the two plates are cut, they need to be realigned again due to transportation in the subsequent process before double-sided welding can be performed, which greatly increases the time required for production and is not conducive to improving production efficiency.

Two sets of electric grippers 15 clamp the two metal plates. At this time, two sets of stepper motors 13 are driven. The stepper motors 13 move to the right on the screw rod 12. When the symmetrical positions of the two metal plates touch the X-shaped cutting blade 16, they will be cut, thereby forming an X-shaped section. During cutting, the four rotating rods 14 will rotate clockwise at the same time to provide additional downward pressure, and the cut waste will fall uniformly into the frame 11 for easy cleaning.

The two stepper motors 13 on the left side move toward the transport component 3 on the screw rod 12 through the remaining two electric grippers 15.

During the movement, the longitudinal space of the L-shaped frame 42 is continuously shortened, and the two pressing rollers 46 gradually contact the metal plate. During the pressing process, the two sets of bent rods 45 rotate outwards relative to each other under the action of the torsion springs 44, and press the metal plate under the elastic action of the torsion springs 44, forming an upper and lower clamping between the rotating rollers 32, thereby preventing deviation. The welding assembly 5 includes a moving block 51, which is movably clamped inside the track 24. The moving block 51 is equipped with an electric wheel on the track 24.

A welding rod tube 54 is inserted into the trapezoidal block 53. A welding head 55 is fixedly installed in the middle of the fixing ring 52. The two symmetrically mounted welding heads 55 are driven by the moving block 51 to move in the track 24 with the movable curtain 25, and the welding wire is passed through the welding rod tube 54. The two welding heads 55 are started to perform double-sided welding on the cutting positions of the two metal plates at the same time.

At this time, the clamping effect of the fixing component 4 is released, and the entire metal plate reaches the discharge component 6 under the transportation effect of the transportation component 3. The second motor 65 drives the roller 66 to rotate, lift it, and slide in the round rod 62 area formed under the support of the fixed block 61 and the inclined rod 63, so as to facilitate the next process of taking it.

[0019] Working principle: When using the device to perform double-sided welding on metal plates, firstly, two metal plates to be welded are symmetrically positioned and placed on the cutting assembly 1, and two sets of electric grippers 15 clamp the two metal plates, and then two sets of stepper motors 13 are driven, and the stepper motors 13 move to the right on the screw rod 12. When the symmetrical positions of the two metal plates touch the X-shaped cutting knife 16, they will be cut, thereby forming an X-shaped section. During cutting, the four rotating rods 14 will rotate clockwise at the same time to provide additional downward pressure, and the cut waste will fall uniformly into the frame 11, which is convenient for cleaning; After the plate is cut, part of it will be clamped by the electric gripper 15 and transported to the top of the transport assembly 3 via the stepper motor 13. At this time, the two right electric grippers 15 are released from clamping the metal plate, and the first motor 34 is started. The rotation speed of the first motor 34 is kept consistent with the movement speed of the stepper motor 13. The first motor 34 drives the multiple rollers 32 to rotate clockwise through the belt 33, so as to transport the metal plate to the right. At this time, the fixing component 4 is started synchronously, and the L-shaped frame 42 gradually moves to the right in the inclined groove 41. During the movement, the longitudinal space of the L-shaped frame 42 is continuously shortened, and the two pressure rollers 46 will gradually contact the metal plate. During the clamping process, the two sets of bent rods 45 rotate outwards relative to each other under the action of the torsion spring 44, and under the elastic action of the torsion spring 44, the metal plate is clamped to form an upper and lower clamp between the rollers 32 to prevent deviation. When the metal plate is continuously transported, the two electric clamps 15 close to the transport component 3 are first slightly loosened. At this time, the two electric clamps 15 are equivalent to the guide grooves, and the stepper motor 13 at the bottom thereof stops moving. The two stepper motors 13 on the left side move toward the transport component 3 on the screw rod 12 through the remaining two electric clamps 15. When most of the two metal plates are between the transport component 3 and the fixing component 4, the remaining two electric clamps 15 are loosened again to cancel the clamping of the metal plate. Through the continuous transportation of the transport component 3 and the fixing component 4, the metal plate is moved to the welding area and then stopped. The two symmetrically mounted welding heads 55 are driven by the moving block 51 to move in the track 24 with the movable curtain 25, and the welding wire is passed through the welding rod tube 54. The two welding heads 55 are started to perform double-sided welding on the cutting positions of the two metal plates at the same time. The movable curtain 25 will prevent foreign matter from splashing into the track 24. When welding is completed, the two metal plates become a solid whole. At this time, the clamping effect of the fixing component 4 is released, and the entire metal plate reaches the discharge component 6 under the transportation effect of the transportation component 3. The second motor 65 drives the roller 66 to rotate, lift it, and slide in the round rod 62 area formed under the support of the fixed block 61 and the inclined rod 63, which is convenient for the next process to take. The work flow ends here.
