Description

TECHNICAL FIELD

[0001] The application relates to the technical field of welding forming, in particular to a high-precision GIS support integrated welding forming process and equipment. BACKGROUND

[0002] GIS is a gas-insulated enclosed combination electric appliance, which is mostly composed of a circuit breaker, a current transformer, a voltage transformer, a disconnector, a grounding switch and a surge arrester, and is assembled in a closed metal shell, and a certain pressure of insulating gas is filled in the metal shell, and has the advantages of small land occupation and space occupation, personnel safety, small influence of climate, no fire, no environmental damage, good electromagnetic compatibility, long maintenance period and long service life.

[0003] The metal shell of the GIS generally needs to be grounded, and a support is usually arranged under the metal shell to help support.

[0004] Most of the supports are made of metal plates and are welded together, and multiple components need to be spliced, such as a bottom plate, a vertical plate and a reinforcing rib. The traditional welding needs to position each component manually, and then weld point by point, which is low in efficiency and poor in consistency, and the integrated welding forming mostly completes the processing of multiple welding points or surfaces in one process, which can greatly increase the efficiency.

[0005] The support of the high-precision GIS has high precision requirements when adapting to the electrical equipment, so that high dimensional accuracy is required. During integrated welding, the metal plate part is mostly welded by heat, and multiple points need to be welded at the same time, which is easy to generate a large amount of heat and then cause thermal deformation, resulting in cracking of the welding points and affecting the dimensional accuracy. Some integrated welding cools the welding points by various means to reduce the influence of thermal deformation. Among them, the cooling gas cooling method introduces cooling gas into the welding area, but due to the shielding of the plate body and the seat body, the area where the cooling gas is introduced is located above the welding point, which cannot form cross coverage of the upper and lower sides of the component and the welding path at the welding point, causing incomplete coverage of the welding point and the component cooling area. In addition, during cooling, the welding point moves and the heat generation position changes as the welding occurs, and the cooling gas cannot be directed to the welding point path for cooling, resulting in a decrease in cooling effect.

[0048] In addition, as shown in Figure 3 The multi-point welding assembly 51 comprises a mounting head 511, a vertical control member 512 and a welding head 513, one end of the mounting head 511 is rotatably mounted on the mounting vertical plate 533, the welding head 513 is arranged at the other end of the mounting head 511, one end of the vertical control member 512 is rotatably mounted on the mounting vertical plate 533, and the other end of the vertical control member 512 is rotatably connected to the middle of the mounting head 511, the vertical control member 512 is an electrically driven control push rod, and the vertical control member 512 forms a vertical control of the mounting head 511, and the welding head 513 at the end of the mounting head 511 can be controlled to perform welding operation through the control of the vertical control member 512.

[0049] As shown in Figure 3 The follow-up cooling assembly 6 comprises an external pipe 61, a sliding control member 62 and a cooling pipeline 63, the sliding control member 62 is arranged on one side of the mounting head 511, the external pipe 61 penetrates through the mounting vertical plate 533, the pipe body of the external pipe 61 penetrates through the sliding control member 62, one end of the cooling pipeline 63 is connected to the external pipe 61, and the other end of the cooling pipeline 63 is arranged in abutment with the welding portion at the end of the welding head 513, the end of the welding head 513 is lower than the cooling pipeline 63, so that the welding head 513 contacts the welding point during welding, and the cooling pipeline 63 is higher than the welding point, the external pipe 61 can be externally connected to a pipeline for introducing cooling gas, and the pipe body of the external pipe 61 can slide along the length direction of the mounting head 511 under the control of the sliding control member 62, so that the cooling pipeline 63 at the end of the external pipe 61 can be controlled to slide according to the length of the welding head 513, and the cooling pipeline 63 can always follow the welding head 513 to adjust the welding portion at the end of the welding head 513.

[0050] It should be noted that the sliding control member 62 and the mounting head 511 can move synchronously, so that when the mounting head 511 drives the welding head 513 to move along the welding path, the cooling pipeline 63 also moves synchronously, thereby forming a follow-up state in which the area for guiding the cooling gas moves synchronously with the welding point.

[0051] As Figure 7 and Figure 8 shown, the cooling pipeline 63 includes a path cooling pipe 631 and a surrounding cooling pipe 632, the path cooling pipe 631 is connected to the outer connecting pipe 61 on one side and is transversely arranged on the side of the welding head 513 on the other side, the path cooling pipe 631 moves synchronously with the welding head 513, and the path cooling pipe 631 is located on the moving path of the welding head 513, one end of the surrounding cooling pipe 632 is connected to the path cooling pipe 631, and the pipe body of the surrounding cooling pipe 632 surrounds above the welding head 513, and the other end air outlet of the surrounding cooling pipe 632 is located on the side of the welding head 513 away from the path cooling pipe 631, and the path cooling pipe 631 and the surrounding cooling pipe 632 form a cooling effect on both sides of the moving path of the welding head 513 and the outside of the welding head 513;

[0052] As Figure 8 shown, the path cooling pipe 631 and the surrounding cooling pipe 632 are both provided with gas guide holes for guiding the cooling gas, and the gas guide holes of the path cooling pipe 631 are opposite to the welding path, and the gas guide holes of the surrounding cooling pipe 632 are opposite to the welding head 513 and the other side of the welding head 513, as Figure 8 shown, the path cooling pipe 631 can cool the components near the welding path in advance before welding, and at the same time, the path cooling pipe 631 can move with the welding head 513 during the welding process, helping to cool the completed part again, thus achieving twice cooling effect, in addition, the surrounding cooling pipe 632 can guide the cooling gas to the other side of the welding head 513, and when the welding head 513 welds and moves, the cooling gas guided by the surrounding cooling pipe 632 can cool the completed point in the first time, and also can help to cool the welding head 513, thus forming double cooling effect, which can prevent the thermal deformation and cracking of the welding point, and also can help to reduce the temperature of the welding head 513 to prevent the welding head 513 from being damaged due to overheating.

[0053] As Figure 4 shown, the damping base 31 includes a center support block 311 and a corner support block 312, the center support block 311 and the corner support block 312 are both honeycomb-shaped bases, and are distributed at the center of the end of the support base 2 and the four corners, the height of the corner support block 312 is higher than that of the center support block 311, the bottom cooling assembly 7 is arranged on the corner support block 312, and the cooling end of the bottom cooling assembly 7 is close to the welding head 513 directly below, as Figure 4As shown, the height of the corner support block 312 is higher than that of the center support block 311, so that the center support block 311 and the corner support block 312 form a centrally concave support structure, which can allow the welding base body to fit in the concave portion during welding, and the corner support block 312 fits the four corners of the base body, and the corner support block 312 can also support the welding part when it is close to the base body.

[0054] As shown in Figure 9 and Figure 10 The bottom cooling assembly 7 includes a through pipe 71 and a bottom cooling cross pipe 72, the through pipe 71 vertically penetrates the edge of the support base 2 and the corner support block 312, and the bottom end of the through pipe 71 can be connected to a cold air pipe, and the bottom cooling cross pipe 72 is transversely arranged at the end of the through pipe 71, and the bottom cooling cross pipe 72 is located between two corner support blocks 312 on the same side, so that the bottom cooling cross pipe 72 is transversely arranged directly below the moving path of the welding head 513, as shown in Figure 10 The through pipe 71 can be connected to a cold air pipe in advance, and when the welding part is close to the base body, cold air is introduced into the moving path of the welding part through the bottom cooling cross pipe 72, so as to cool the parts near the welding path, and then welding is performed. At this time, the parts in the cooling state are less affected by the heat during welding, and the parts near the welding point are prevented from being deformed due to high heat during welding.

[0055] The follow-up cooling area formed above the welding point and the welding path by the path cooling pipe 631 and the surrounding cooling pipe 632, and the cooling area below the welding part and the welding path by the bottom cooling cross pipe 72, can form an intersecting cooling coverage area above and below the welding position and the welding path, avoiding the formation of a cooling dead angle above and below the welding position and the welding path due to the shielding of the welding part.

[0056] As shown in Figure 5 and Figure 6 The array damping buffer assembly 4 includes a damping spring 41 and a damping member connector 42, the damping member connector 42 is arranged at the corners of the four sides of the damping base 31, and the damping spring 41 is arranged outside the damping member connector 42, so that the plurality of damping member connectors 42 and the damping spring 41 can be arranged outside the damping base 31, forming an array damping effect on the damping base 31.

[0057] It needs to be clear that when multiple welding points are welded at the same time, too many welding positions at the same time are easy to cause the vibration and deviation of the plate, thereby affecting the precision of the welding point position, and further affecting the precision of the whole support. The center support block 311 and the corner support block 312 support the base body part of the foundation. At this time, during welding, the vibration will be transmitted to the bottom pad 32 and the array damping buffer assembly 4 part. The array damping effect formed by the array damping buffer assembly 4 removes the polarization force in multiple directions.

[0058] Working principle: insert the plate body part to be welded between the clamping end of the clamping driving member 523 and the end of the clamping stand 522, start the clamping driving member 523, clamp the plate body to be welded horizontally at the end of the clamping stand 522 through the driving end of the clamping driving member 523, then place the base body part of the foundation on the damping base 31. At this time, the forward driving member 521 can be started to move the plate body part to be welded forward and adhere to one side of the base body. The outer connecting pipe 71 connects the cooling gas pipeline, and the cooling gas is introduced into the adhesion part of the plate body to be welded and the base body through the bottom cooling horizontal pipe 72, thereby cooling the lower end of the part near the welding path. At the same time, the outer connecting pipe 61 connects the pipeline for introducing cooling gas, and the cooling gas is introduced into the path cooling pipe 631 and the surrounding cooling pipe 632, so that the cooling gas discharged through the path cooling pipe 631 cools the upper end of the part near the welding path, so that the follow-up cooling assembly 6 and the bottom cooling assembly 7 form an intersecting cooling area on the upper and lower sides of the welding path, and the surrounding cooling pipe 632 can introduce cooling gas to the periphery of the welding head 513 and the side away from the path cooling pipe 631, thereby forming omnidirectional cooling of the welding head 513 and cooling of the welding point. During work, the mounting head 511 and the welding head 513 are started, and the welding head 513 is close to the position where the plate body to be welded and the base body adhere under the control of the vertical control member 512. Multiple welding heads 513 work simultaneously to complete multi-point simultaneous welding. During welding, the horizontal and vertical driving of the horizontal push rod 531 and the vertical push rod 532 drives the mounting vertical plate 533 and the entire multi-point welding assembly 51 to move horizontally and vertically, so that the welding point moves along the position where the plate body to be welded and the base body adhere. With the movement of the welding head 513, the path cooling pipe 631 moves, and a large amount of heat is generated during welding. The cooling gas discharged through the surrounding cooling pipe 632 cools the welded point first, and also cools the welding head 513. In addition, the cooling gas discharged by the path cooling pipe 631 also cools the welded part again, forming a double-effect cooling effect. Therefore, before, during and after welding, a cooling effect is formed on the welding path, thereby effectively avoiding the thermal deformation and cracks caused by high heat during multi-point simultaneous welding, and ensuring the welding precision.

[0061] S2, at this time, the through pipe 71 is connected with the cold gas pipeline, the cold gas is introduced into the fitting part of the plate body to be welded and the base seat through the bottom cooling horizontal pipe 72, so that the lower end of the part near the welding path is cooled, at the same time, the pipeline 61 is connected with the pipeline for introducing cooling gas, the cooling gas is introduced into the path cooling pipe 631 and the surrounding cooling pipe 632, so that the cooling gas introduced by the path cooling pipe 631 cools the upper end of the part near the welding path, at the same time, the surrounding cooling pipe 632 can introduce the cooling gas to the periphery of the welding head 513 and the side away from the path cooling pipe 631, to form omnidirectional cooling of the welding head 513 and cooling of the welding point;

[0062] S3, the mounting head 511 and the welding head 513 are started, under the control of the vertical control member 512, the welding head 513 is close to the welding point to complete welding, at the same time, the horizontal and vertical driving of the horizontal push rod 531 and the vertical push rod 532 drives the horizontal and vertical movement of the mounting vertical plate 533 and the multi-point welding assembly 51, and controls the movement of the plurality of welding heads 513 to complete welding during welding;

[0063] S4, when the welding head 513 is welded and moved, the cooling gas introduced by the surrounding cooling pipe 632 cools the welded point for the first time, at the same time, the welding head 513 is cooled, forming double-effect cooling, in addition, with the movement of the welding head 513, the path cooling pipe 631 follows the movement to cool the welded part again.

First, insert the plate to be welded between the clamping end of the clamping drive (523) and the end of the clamping stand (522). Start the clamping drive (523) to clamp the plate to be welded. Then, place the base part of the foundation on the vibration damping base (31). At this time, start the forward drive (521) to move the plate to be welded forward and close to the side of the base part of the foundation for contact. S2. At this time, a cold air pipe can be connected to the through pipe (71) to introduce the cold air through the bottom cooling horizontal pipe (72) to the joint between the plate to be welded and the base body, thereby cooling the lower end of the component located near the welding path. At the same time, a pipe for introducing cooling gas is connected to the outside pipe (61) to introduce the cooling gas into the path cooling pipe (631) and the surrounding cooling pipe (632). Thus, the cooling gas discharged through the path cooling pipe (631) cools the upper end of the component located near the welding path.

During welding, multiple welding heads (513) are controlled to move and complete the welding. S4. When the welding head (513) is welding and moving, the cooling gas discharged from the surrounding cooling pipe (632) cools the point where the welding is completed at the first time, and cools the welding head (513) at the same time, forming a double cooling effect. In addition, as the welding head (513) moves, the path cooling pipe (631) moves along with it, and cools the part where the welding is completed again.
