Description

Technical Field

[0001] The present application relates to the technical field of welding systems, and in particular to a composite plate equipment welding system. Background Art

[0002] In the field of composite plate equipment manufacturing, especially in the manufacturing process of cylinder-type structural parts, welding is a critical and complex process. Composite plates are usually composed of rare metal cladding and steel base. The differences in physical and chemical properties of these two materials make it impossible to weld them directly. Therefore, during the manufacturing process, it is necessary to partially remove the cladding metal on both sides of the composite plate welding joint in order to weld the steel base first.

[0003] After the steel base is welded, in order to restore and strengthen the function of the rare metal cladding, the traditional practice is to install a pad and a cover plate at the location where the cladding metal is removed. The pad is made of the same material as the rare metal and is used for welding with the rare metal cladding, while the cover plate is covered on the pad to increase the strength and sealing of the structure.

[0004] However, due to the limitation of the width of rare metal plates, pads and cover plates are generally cut into long strips with limited length, which requires manual welding section by section. This process is not only cumbersome and increases manufacturing costs, but also inefficient. Utility Model Content

[0005] The embodiment of the present application provides a composite plate equipment welding system to solve the technical problem in the prior art that due to the limitation of the width of rare metal plates, the pads and cover plates are usually cut into long strips with limited length and need to be manually welded section by section, resulting in low efficiency.

[0006] An embodiment of the present application provides a composite plate equipment welding system, comprising a welding auxiliary equipment, a support platform, a uncoiler, a tape straightener, a forming mechanism, a wire feeder, at least one welding gun and at least one wire feeding nozzle; the welding auxiliary equipment is installed on the ground; the support platform is installed at one end of the welding auxiliary equipment away from the ground; the wire feeder, the uncoiler, the tape straightener and the forming mechanism are all installed on the top surface of the support platform, and are arranged at intervals along the length direction of the support platform; the forming mechanism is used to form a pad or a cover plate after being straightened by the tape straightener; the welding gun is arranged on a side of the forming mechanism away from the support platform, and is connected to the welding auxiliary equipment; one end of the wire feeding nozzle is connected to the wire feeder, and the other end thereof corresponds to the welding gun.

[0007] In a possible implementation, the composite plate equipment welding system further includes a pressing wheel; one end of the pressing wheel is connected to the pressing mechanism, and the other end of the pressing wheel is used to press the straightened pad or cover plate against the object to be welded.

[0008] In a possible implementation, the welding auxiliary equipment includes a welding platform, a welding machine, a gas cylinder and a control cabinet; the gas cylinder, the welding platform, the control cabinet and the wire feeder are all connected to the welding machine; the welding platform is installed on the ground, and the support platform is installed at one end of the welding platform away from the ground; the gas cylinder is connected to the welding gun; and the control cabinet is connected to the welding platform.

[0009] In a possible implementation, the welding platform is a welding cross arm or a welding robot.

[0010] In a possible implementation, the composite plate equipment welding system further includes a laser weld seam tracker; the laser weld seam tracker is disposed on the pressing mechanism and is used to track the welding process.

[0011] In a possible implementation, the composite plate equipment welding system further includes a shearing mechanism; the shearing mechanism is disposed on the pressing mechanism and is used to cut the remaining backing plate or cover plate according to the length of the pressed backing plate or cover plate when the welding is nearly completed.

[0015] The composite plate equipment welding system provided in the embodiment of the present application includes a welding auxiliary device, a support platform, an unwinder, a tape straightening machine, a forming mechanism, a wire feeder, at least one welding gun and at least one wire feeder nozzle. The working process is as follows: first, the pad or cover plate is installed on the unwinder, and then the unwinder is started, and its main shaft rotates to drive the pad or cover plate to gradually unfold from a roll to a straight strip. Then the straight strip pad or cover plate is further straightened by the tape straightening machine and smoothly transported to the forming mechanism. In the forming mechanism, the straight strip pad or cover plate is given the desired shape and is extended to the right end of the object to be welded so that the welding gun can easily spot weld the pad or cover plate after forming.

In addition, the system reduces the splicing welds of the pad or cover plate in the length direction, reduces the risk of leakage, and further improves the reliability and safety of the system.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0023] The present application embodiment provides a composite plate equipment welding system, such as Figures 1 to 3 As shown. The composite plate equipment welding system includes a welding auxiliary device 1, a support platform 2, a uncoiler 3, a tape straightening machine 4, a forming mechanism 5, a wire feeder 6, at least one welding gun 7 and at least one wire feeding nozzle 8. The welding auxiliary device 1 is installed on the ground. The support platform 2 is installed at one end of the welding auxiliary device 1 away from the ground. The wire feeder 6, the uncoiler 3, the tape straightening machine 4 and the forming mechanism 5 are all installed on the top surface of the support platform 2, and are arranged at intervals along the length direction of the support platform 2. The forming mechanism 5 is used to form the pad or cover plate after being straightened by the tape straightening machine 4. The welding gun 7 is arranged on the side of the forming mechanism 5 away from the support platform 2, and is connected to the welding auxiliary device 1. One end of the wire feeding nozzle 8 is connected to the wire feeder 6, and the other end thereof corresponds to the welding gun 7.

[0024] The present application does not limit the position and assembly method of the wire feeder 6 , the uncoiler 3 and the tape straightening machine 4 .

[0025] Specifically, the present application uses a rare metal coil as a backing plate or cover plate material. The rare metal coil of the present application is placed on an unwinding machine 3. The unwinding machine 3 is used to drive the rare metal coil to unfold.

[0026] The pressing mechanism 5 of the present application is functionally equivalent to the arc pressing die, bending machine or similar tooling equipment in the prior art.

[0027] When the cylinder adopts the plate rolling process, a longitudinal weld joint will be formed, and the welding shape at the joint is an arc. However, the pads and cover plates actually used are often flat plate shapes, which easily cause stress concentration at the weld, causing the weld to be easy to tear, especially in composite plate equipment operating under high temperature and high pressure environment. The pressing mechanism 5 of the present application can accurately press the curvature of the pad or cover plate according to the specific curvature of the weld, which not only reduces the stress concentration at the weld, effectively avoids the problem of the weld being easy to tear due to excessive stress, but also reduces the risk of leakage, thereby improving the reliability and safety of the system during use.

[0028] It should be noted that the working process of the composite plate equipment welding system is as follows: first, the pad or cover plate coil is installed on the uncoiler 3, and then the uncoiler 3 is started, and its main shaft rotates to drive the pad or cover plate to gradually unfold from a coil to a straight strip. Then the straight strip pad or cover plate is further straightened by the coil straightening machine 4 and smoothly transported to the pressing mechanism 5. In the pressing mechanism 5, the straight strip pad or cover plate is given the required shape and extended to the right end of the object to be welded so that the welding gun 7 can easily spot weld the pad or cover plate after pressing. Next, the welding auxiliary equipment 1 is turned on, and the welding auxiliary equipment 1 drives the support platform 2 to move, thereby driving the welding gun 7 to weld according to the predetermined trajectory. During the welding process, the wire feeder 6 continues to feed wire to ensure the continuity of the welding process, and the uncoiler 3 also remains in the uncoiling state. When the welding is nearly completed, the operator cuts it according to the length of the remaining pressed pad or cover plate. After cutting, the subsequent pad or cover plate continues to move forward under the push of the coil straightening machine 4, pushing the pad or cover plate in front to complete the remaining welding work. Therefore, the composite plate equipment welding system realizes the continuous automatic installation and welding of the pad or cover plate, which not only avoids the cumbersome process of cutting the pad or cover plate into narrow strips in the traditional method, but also eliminates the steps of manual assembly spot welding and subsequent protection of the weld, thereby reducing the process, reducing production costs, and improving production efficiency. In addition, the system avoids the splicing welds of the pad or cover plate in the length direction, reduces the risk of leakage, and further improves the reliability and safety of the system.

[0029] In the embodiment of the present application, the composite plate equipment welding system further comprises a pressing wheel 9. One end of the pressing wheel 9 is connected to the pressing mechanism 5, and the other end thereof is used to press the straightened backing plate or cover plate against the object to be welded.

[0030] It should be noted that the pressure wheel 9 can make the backing plate or the cover plate fit tightly with the object to be welded, thereby reducing the risk of leakage and improving the reliability of the system.

[0031] In the embodiment of the present application, the welding auxiliary equipment 1 includes a welding platform 11, a welding machine 12, a gas cylinder 13 and a control cabinet 14. The gas cylinder 13, the welding platform 11, the control cabinet 14 and the wire feeder 6 are all connected to the welding machine 12. The welding platform 11 is installed on the ground, and the support platform 2 is installed at one end of the welding platform 11 away from the ground. The gas cylinder 13 is connected to the welding gun 7. The control cabinet 14 is connected to the welding platform 11.

[0032] It should be noted that the control cabinet 14 of the present application is used to control the movement of the welding platform 11 and to set and adjust welding parameters.

[0033] In the embodiment of the present application, the welding platform 11 is a welding cross arm or a welding robot.

[0034] It should be noted that the welding cross arm or the welding robot has a high-precision positioning capability, which can ensure the accurate movement of the welding gun 7 in the three-dimensional space, thereby achieving accurate welding of the weld.

[0035] In the embodiment of the present application, the composite plate equipment welding system further comprises a laser weld seam tracker which is arranged on the pressing mechanism 5 and is used to track the welding process to prevent the pad or cover plate from deforming during the welding process and the welding gun 7 from deviating from the weld seam.

[0036] In the embodiment of the present application, the composite plate equipment welding system further comprises a shearing mechanism which is arranged on the pressing mechanism 5 and is used to cut the remaining pressed backing plate or cover plate according to the length thereof when the welding is nearly completed.

[0037] Specifically, the shearing mechanism includes a telescopic member. When a shearing operation is required on the pad or cover plate, the telescopic member will extend to perform the cutting task; when shearing is not required, the telescopic member will automatically retract to avoid interfering with other normal working processes of the system.

[0038] In the embodiment of the present application, there are two welding guns 7, and two wire feeding nozzles 8 are provided. The two welding guns 7 are arranged at intervals along the width direction of the pressing mechanism 5. One end of the two wire feeding nozzles 8 is connected to the wire feeder 6, and the other end thereof is connected to the corresponding welding gun 7 respectively.

[0039] Specifically, the pressing mechanism 5 of the present application is provided with a support member, and two welding guns 7 are arranged at intervals along the length direction of the support member. The two welding guns 7 of the present application weld simultaneously, which not only enhances the stability and efficiency of the welding process, but also effectively prevents welding deformation problems caused by concentrated welding heat, thereby improving the overall quality of welding.

[0040] In the embodiment of the present application, the welding gun 7 is a argon arc welding gun or a laser welding gun.
