Description

Technical Field

[0001] The invention relates to the technical field of curtain wall structure processing, and more specifically to a curtain wall keel assembling and welding device. Background Art

[0002] Curtain wall is a structural form of building facade, which is composed of multiple components, mainly composed of curtain wall panels, curtain wall keels, structural brackets and curtain wall accessories. Among them, curtain wall keels and structural brackets together form a support system, which is connected to the building structure to form a structural support for the curtain wall as a whole.

[0003] Among them, the curtain wall keel is a skeleton system used to support the curtain wall panels, usually made of aluminum alloy, steel and other materials. It is responsible for bearing the weight of the panels and wind loads, and transferring the loads to the main structure of the building. During the curtain wall construction, the keel and the skeleton need to be fixed. Among them, in order to ensure the stability and structural strength of the skeleton, most of the structural connections need to be welded. However, in the past, welding was mostly performed at the construction site while the keel skeleton was assembled. In order to improve construction efficiency, more and more exterior curtain walls in the existing technology use unit curtain walls, that is, for some large-area curtain wall structures, they are divided into unit modules, which are processed and assembled in the factory to form each unit module, and then transported to the construction site for installation.

[0004] When the factory makes the keel frame of the prefabricated curtain wall, it needs to use a positioning device to position the various rod structures and connecting structures of the frame for accurate welding. In order to avoid displacement of the structures during welding, the fixing device needs to stably fix the structures and clamp them firmly to ensure that the welding accuracy of the frame is not affected. At the same time, in order to effectively reduce the stress and deformation during welding and improve the quality and stability of welding, it is necessary to effectively preheat the parts to be welded of each structure, increase the temperature of the material near the welding part of the rod structure, reduce the stress concentration and deformation caused by thermal stress during welding, thereby reducing the risk of cracks or deformation caused by welding, and improve the grain structure of the material near the area to be welded of the structure to make it more uniform and stable, thereby improving the strength and toughness of the welding.

[0005] For some larger unit keel structures, due to the large number of various connection structures, there are relatively more points that need to be welded. In order to improve production efficiency, it is necessary to use multiple sets of automated welding equipment to perform multi-station synchronous welding, so that multiple points can be welded at the same time, effectively improving welding efficiency.

[0006] For a keel structure with a longer single body and more connecting structures, for example, a structure with multiple auxiliary rods or connecting parts evenly distributed on a longer main rod, when welding, it is necessary to assemble the auxiliary rods or connecting parts on the main rod, and then weld them after they are accurately fixed by a fixing device. Since the main rod is a straight rod, the direction of deformation due to heat is single. During actual processing, under the influence of preheating and welding heat, the material as a whole tends to elongate. However, since the main rod is fixed by a fixing device, if the fixing strength of the fixing device is relatively low, the main rod is prone to slipping with the fixing device when it is deformed, affecting the accuracy between two adjacent welds, and the surface of the material is also easily scratched by the fixing device. If the fixing strength of the fixing device is high, the main rod will form a large stress concentration near the fixing device, and even produce plastic deformation, affecting the material strength and material quality at the welding position. Summary of the invention

[0007] The present invention provides a curtain wall keel assembly welding device to solve the problem that when existing welding equipment is welding at multiple points at the same time, the material as a whole tends to stretch due to the influence of preheating and welding heat. However, since the main rod is fixed by a fixing device, the material is not easily deformed and stretched due to thermal expansion, which will affect the accuracy between two adjacent welding points and affect the material strength and material quality of the welding position.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Refer to the instruction manual Figures 1 to 12 A curtain wall keel assembly welding device comprises a base 1, on which a positioning unit 2, a welding unit 3 and a heating device are arranged, the positioning unit 2 is used to fix a main rod 4 and a secondary rod 5, and each positioning unit 2 is respectively arranged corresponding to a welding point area between the main rod 4 and the secondary rod 5, and the heating device is used to heat and preheat the main rod 4 and the secondary rod 5, especially the welding point position of the main rod 4 and the secondary rod 5;

[0036] The positioning unit 2 includes a positioning seat 21, on which a clamp assembly 22 is arranged, and the clamp assembly 22 is arranged in two groups, and the two groups of clamp assemblies 22 are respectively used to clamp and fix the main rod 4 and the auxiliary rod 5, and the welding unit 3 includes a welding gun 31, and the welding gun 31 is used to weld the contact area between the main rod 4 and the auxiliary rod 5;

[0037] The base 1 is also provided with a pressure unit 6, which is located between two adjacent positioning units 2. The pressure unit 6 includes a pressure head assembly 61, which is located above the main rod 4. The pressure head assembly 61 is connected to the base 1 through a first pressure driver 62. Specifically, the pressure unit 6 also includes a fixing frame 63, which is fixedly mounted on the base 1. The first pressure driver 62 is mounted on the fixing frame 63 and is used to drive the pressure head assembly 61 to move up and down.

[0038] Before welding, the auxiliary rod 5 is first placed on all the positioning units 2, and then each auxiliary rod 5 is also placed on the corresponding positioning unit 2 and spliced ​​with the main rod 4. The main rod 4 and the auxiliary rod 5 are positioned and fixed by the clamp assembly 22 to ensure that the material at the welding point will not move, and then the main rod 4 and the auxiliary rod 5 are preheated by the heating device. When the main rod 4 and the auxiliary rod 5 are welded by the welding gun 31, during the preheating and welding process, the first pressure driver 62 drives the pressure head assembly 61 to move downward to squeeze the main rod 4, with the adjacent two positioning units 2 and the clamp assembly 22 on the positioning unit 2 as support points, and with the help of the downward pressure of the pressure head assembly 61, the material of the main rod 4 between the two adjacent positioning units 2 is generated as shown in the appendix of the specification. Figure 4 The slight bending shown in the figure is within the elastic deformation of the main rod 4 itself. Due to the bending caused by the material, when the preheating and welding cause the material of the main rod 4 to heat up and expand, the elongation of the material will only increase the bending degree of the main rod 4, and the bending degree is still within the elastic deformation range of the main rod 4. Since the thermal deformation of the main rod 4 is stretched, the heating and expansion of the main rod 4 will not cause displacement at the welding point of the main rod 4, nor will it cause displacement between the main rod 4 and the clamp assembly 22, and will not cause large compressive stress in the material at the clamp assembly 22 due to the inability of the material to expand and release, thereby affecting the actual quality of the main rod 4. Moreover, the deformation of the main rod 4 mentioned above is within its own elastic deformation range. After the welding is completed, the pressure head assembly 61 is controlled to rise to relieve the pressure. After the temperature returns to normal temperature, the main rod 4 can return to its original shape.

[0039] Furthermore, a plurality of welding units 3 are provided on the base 1, and a movable guide rail 11 is fixedly installed on the base 1, and the movable guide rail 11 is distributed along the length direction of the main rod 4, that is, the movable guide rail 11 is distributed along the X-axis direction. The welding unit 3 also includes a movable driver 32, and the movable driver 32 is slidably arranged on the movable guide rail 11, and a Y-axis driver 33 is arranged on the movable driver 32, and a Z-axis driver 34 is arranged at the output end of the Y-axis driver 33, and a rotation driver 35 is arranged at the output end of the Z-axis driver 34, and the welding gun 31 is installed on the output end of the rotation driver 35, wherein the movable driver 32 is used to drive the welding gun 31 to move along the X-axis direction, the Y-axis driver 33 is used to drive the welding gun 31 to move along the Y-axis direction, the Z-axis driver 34 is used to drive the welding gun 31 to move up and down along the Z-axis direction, and the rotation driver 35 is used to drive the welding gun 31 to rotate.

[0040] It should be noted that, by setting up multiple groups of welding units 3, during welding, the mobile driver 32, the Y-axis driver 33, and the Z-axis driver 34 drive the welding gun 31 to the specified position, and multiple welding guns 31 perform synchronous welding, which can greatly improve the welding efficiency, and each welding gun 31 can be freely controlled to adapt to a variety of welding conditions, and the welding gun 31 is driven to rotate by the rotating driver 35, and the welding direction and angle can be adjusted, etc., wherein the mobile driver 32 and the moving guide rail 11 are commonly used linear drive devices, such as a screw motor, etc., and the Y-axis driver 33 and the rotating driver 35 can use a screw motor, or a linear drive structure such as a cylinder, and the rotating driver 35 can use a motor assembly, all of which are commonly used existing technologies and will not be repeated in this embodiment.

[0041] Refer to the instruction manual Figure 2 and Figure 4 , there is a suspended area between two adjacent positioning seats 21, and each positioning seat 21 is provided with a pad structure for supporting the main rod 4. Under the support of the positioning seat 21 and the pad, the main rod 4 in the suspended area between the two adjacent positioning seats 21 is in a suspended state, and there is no support at the bottom. In this embodiment, the heating device is a flame nozzle 23, which is fixedly arranged on the positioning seat 21, and the flame nozzle 23 is used to spray flame to the main rod 4 and the auxiliary rod 5 to heat the main rod 4 and the auxiliary rod 5. Since the main rod 4 between the two adjacent positioning seats 21 is in a suspended state and there is no obstruction, the heat conduction effect of the main rod 4 itself is relatively good during preheating and welding, and stress deformation and other problems caused by uneven heat will not occur, further ensuring the quality. Moreover, since the heat conduction block also dissipates heat quickly, the main rod 4 can dissipate heat quickly after welding, shortening the waiting time and improving the processing efficiency.

[0042] For further information, please refer to the attached manual. Figures 8 to 10The clamp assembly 22 includes a clamping plate 222 and a fixing plate 221. The clamping plate 222 is fixedly mounted on the positioning seat 21. The clamping plate 222 is slidably mounted on the fixing plate 221. The clamping plate 222 is connected to the fixing plate 221 through a clamping driver 223. The side of the clamping plate 222 away from the fixing plate 221 is a clamping surface. Each group of clamp assemblies 22 corresponding to the main rod 4 or the auxiliary rod 5 includes at least two clamping plates 222 arranged opposite to each other. The clamping driver 223 is used to drive the clamping plate 222 to approach the main rod 4 or the auxiliary rod 5 to clamp it.

[0043] In the above embodiment, after the clamp assembly 22 clamps the main rod 4, since the main rod 4 needs to bend under pressure, in order to reduce the influence of the clamp assembly 22 on the deformation start area of ​​the main rod 4, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Fig.10 The clamping surface of the clamping plate 222 is provided with a floating pressure block 224 and a fixed pressure block 225. The fixed pressure block 225 is fixedly mounted on the clamping plate 222, and the fixed pressure block 225 is located on the side of the clamping plate 222 close to the welding point of the main rod 4 and the auxiliary rod 5. The floating pressure block 224 is movably mounted on the clamp assembly 22, and the floating pressure block 224 moves in a plane parallel to the clamping surface. In actual use, the fixed pressure block 225 and the floating pressure block 224 are initially clamped. The side wall of the main rod 4 is pressed and clamped together to fix the main rod 4. When the main rod 4 begins to bend, the main rod 4 within the range of the clamping plate 222 also produces a slight bending deformation, and the fixed pressing block 225 close to the welding point is used as the final fixed end to ensure that the main rod 4 near the welding point will not be deformed. Each group of floating pressing blocks 224 is used as a transition stage. The floating pressing blocks 224 can produce corresponding displacements following the slight deformation of the main rod 4. Figure 6 , ensuring that the clamp assembly 22 can still stably clamp the main rod 4.

[0044] For further information, please refer to the attached manual. Fig.10 and Fig.11The clamping plate 222 is provided with a movable groove 2221, and a movable block 2241 is fixedly connected to one side of the floating pressure block 224 close to the movable groove 2221. The movable block 2241 is slidably installed in the movable groove 2221. A plurality of elastic members 226 are provided between the movable block 2241 and the movable groove 2221. The plurality of elastic members 226 are distributed along the circumferential direction of the movable block 2241. The elastic members 226 are preferably spring leaf structures. The elastic members 226 are used to provide radial and circumferential elastic forces to the movable block 2241, so that the elasticity of the plurality of elastic members 226 Under the support, the floating pressure block 224 will be subjected to elastic force no matter which direction it deflects. Even if the floating pressure block 224 is deflected, it will be subjected to torsional elastic force, thereby providing reverse elastic force for the deformation of the main rod 4. Under the action of the elastic force provided by multiple groups of floating pressure blocks 224 and each group of elastic members 226, the main rod 4 near the fixed pressure block 225 can slowly transition to form a small and slow deformation, effectively buffering and protecting the deformation starting position of the main rod 4, while avoiding stress concentration and guiding the main rod 4 to deform.

[0045] It should be noted that, on each clamping plate 222, and in the direction away from the fixed pressure block 225 to the welding point, the smaller the stiffness coefficient of the elastic member 226 between each floating pressure block 224 and the clamping plate 222, in simple terms, the closer the floating pressure block 224 is to the fixed pressure block 225, the more difficult it is to produce displacement, thereby forming an effective and powerful transition connection.

[0046] In the above embodiment, the first pressure driver 62 can adopt a simple and low-cost screw structure, and the pressing head assembly 61 can be controlled to press downward by rotating it. It can also adopt an automatically controlled vertical driving device such as a hydraulic cylinder to realize the downward driving of the pressing head assembly 61. At the same time, the pressing head assembly 61 can also adopt a simple pressing block structure, especially a pressing block structure with a circular arc structure at the bottom, which is used to contact with the main rod 4 and squeeze the main rod 4. However, when only a simple pressing block is used, the contact area between the pressing head assembly 61 and the main rod 4 is small. Although it can provide an effective pressure to the main rod 4, the pressure between the pressing block and the main rod 4 is large, which can easily cause damage to the surface structure of the main rod 4. Therefore, this embodiment also provides a new pressing head assembly 61. For details, refer to the attached manual. Fig.12The pressure head assembly 61 includes an elastic base plate 611 and an elastic seat 612. The elastic seat 612 is installed at the bottom output end of the first pressure driver 62. The elastic base plate 611 is fixedly installed at the bottom of the elastic seat 612. The elastic base plate 611 is made of elastic metal material, the elastic seat 612 is a triangular block structure, and the elastic seat 612 is a rubber structure. Through the above arrangement, when applying pressure, the elastic base plate 611 is actually in contact with the main rod 4 to apply pressure, and through the arrangement of the elastic seat 612, the elastic force provided by the elastic seat 612 to the elastic base plate 611 in the direction from the center to the two ends of the elastic base plate 611 gradually decreases. That is to say, during actual extrusion, the two ends of the elastic base plate 611 can generate corresponding bending deformation while applying pressure to the main rod 4, ensuring that during the pressure application process, the elastic base plate 611 is stably fitted with the main rod 4 and evenly pressurized, so that the surface of the main rod 4 is not easily damaged, which greatly improves the processing quality of the equipment.

[0047] Furthermore, in the above embodiment, since the elastic seat 612 is made of rubber material and the elastic bottom plate 611 is made of heat-conducting material, in order to prevent the elastic seat 612 from being damaged due to overheating, a circulation groove 615 is provided in the elastic seat 612, and an input pipe 613 and an output pipe 614 are also provided on the elastic seat 612. The input pipe 613 and the output pipe 614 are interconnected, and the input pipe 613 is connected to a fluid pump, which is used to transport low-temperature fluid to the circulation groove 615 to cool the elastic seat 612. The pipelines of the input pipe 613 and the output pipe 614 are both high-pressure pipelines, and the liquid in the circulation groove 615 is also a high-pressure liquid, thereby ensuring that the elastic force of the elastic seat 612 is not affected.

[0048] In order to prevent the main rod 4 from being scratched due to the relative displacement generated when the elastic base plate 611 and the main rod 4 are deformed, corresponding oil seepage holes 616 are provided at the bottom of the elastic seat 612 and the elastic base plate 611 of this embodiment. The oil seepage holes 616 are connected to the circulation groove 615, and the low-temperature fluid is preferably lubricating oil. When the elastic base plate 611 is attached to the main rod 4, the fluid pump inputs lubricating oil into the circulation groove 615. While cooling the elastic seat 612, part of the lubricating oil will seep into the area between the elastic base plate 611 and the main rod 4 through the oil seepage holes 616 to effectively lubricate and prevent the main rod 4 from being scratched.

[0049] In the above embodiment, in order to prevent the main rod 4 from excessive bending, this embodiment also provides the following technical solutions. Figure 5 and Figure 7, a plurality of groups of re-pressing units 7 are arranged on the base 1, and each group of re-pressing units 7 is arranged between two adjacent positioning seats 21, and each group of re-pressing units 7 is arranged with two upper and lower ones, and each re-pressing unit 7 includes a pressing plate 71 and a second pressure driver 72, and the pressing plate 71 is arranged corresponding to the main rod 4, and the pressing plate 71 is connected to the base 1 through the second pressure driver 72, and the pressing plate 71 is installed on the output end of the second pressure driver 72. The second pressure driver 72 is preferably a hydraulic cylinder structure, wherein the second pressure driver 72 located at the top is fixedly installed with the base 1 through the fixing frame 63. After welding is completed, the pressing plate 71 is controlled to move by the second pressure driver 72 to squeeze the main rod 4 so that the main rod 4 is kept in a straight state, and then after the cooling is completed, the main rod 4 can maintain a precise straight state, even if the bending of the main rod 4 exceeds its elastic deformation range during the pressure unit 6, it can also be straightened by the re-pressing unit 7 after the processing is completed, so as to improve the processing quality of the equipment.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
