Description

Technical Field

[0001] The present invention relates to the field of floor slab welding, and specifically refers to an intelligent welding device suitable for floor slabs. Background Art

[0002] The floor slab, which is a pressed steel plate supporting the floor concrete, is called a profiled steel sheet. The floor slab meets the requirements of rapid construction of the main steel structure, can provide a firm working platform in a short time, and can adopt the flowing construction method of laying profiled steel sheets on multiple floors and pouring concrete slabs in layers. The floor slab is laid flat on the steel beam or concrete beam, and stud welding needs to be carried out on the edge of the floor slab. Through the connection method of the stud perpendicular to the floor slab, the floor slab has the characteristic of shear resistance, so as to prevent the floor slab from moving when laying cement slurry on the surface of the floor slab.

[0003] In the prior art, generally, a drawn-arc welding gun is used to carry out stud welding on the edge of the floor slab. During operation, a ceramic ring needs to be arranged on the surface of the floor slab, then the bottom end of the stud is inserted into the ceramic ring and the drawn-arc welding gun is driven to work. The bottom end of the stud is melted by the drawn-arc welding gun, and the ceramic ring can define the filling area and shape after the bottom of the stud is melted. However, since the edge of the floor slab is prone to warping after cutting, the ceramic ring is prone to offset after being arranged, and the operator needs to repeatedly perform operations such as putting on the ring, aligning the position of the ceramic ring, and electric welding, resulting in low work efficiency.

[0004] Designing an intelligent welding device suitable for floor slabs to solve the problems existing in the above prior art is the purpose of the research of the present invention. Summary of the Invention

[0005] Aiming at the problems existing in the above prior art, the present invention provides an intelligent welding device suitable for floor slabs, which can effectively solve at least one of the problems existing in the above prior art.

[0006] The technical solution of the present invention is as follows:

[0007] An intelligent welding device suitable for floor slabs, comprising:

[0008] A welding gun, a clamping member is arranged at the bottom end of the welding gun, and a movable rod for moving up and down is arranged on the welding gun;

[0009] A curing enclosure, which is arranged at the bottom end of the movable rod, the curing enclosure is directly below the clamping member, the curing enclosure is of an annular structure, the curing enclosure includes a sleeving part and an enclosing part, the enclosing part is arranged at the lower end of the sleeving part, the diameter of the enclosing part is larger than that of the sleeving part, the sleeving part is used for sleeving on the bottom of the corresponding stud, and the enclosing part is used for enclosing the bottom end of the stud to form a casting cavity;

[0010] Spraying part. After the spraying part moves towards the curing enclosure, the spraying part is inserted into the curing enclosure and brush-coats sintering coating on the inner ring of the curing enclosure. The spraying part is connected to an external sintering coating source.

[0011] Further, the spraying part includes a mounting disk. Along the axial direction of the mounting disk, a plurality of downward spraying rollers are arranged on the bottom surface of the mounting disk. The spraying rollers are provided with a plurality of through holes, and the spraying rollers communicate with corresponding feed pipes. The feed pipes are connected to the sintering coating source.

[0012] Further, the mounting disk is provided with transmission teeth on its outer periphery. The transmission teeth are engaged with corresponding rotating mechanisms, and the rotating mechanisms drive the mounting disk to rotate by a certain angle.

[0013] Further, the spraying part is sleeved on the movable rod, and the movable rod is provided with a driving cylinder for driving the spraying part to move up and down.

[0014] Further, the sintering coating is composed of hexagonal boron nitride, temporary binder, and solvent.

[0015] Further, the temporary binder is polyvinyl alcohol, and the solvent is water.

[0016] Further, a grid-shaped groove is arranged on the inner ring of the enclosure part.

[0017] Further, the welding torch is provided with a locking member for locking the movable rod.

[0018] Therefore, the present invention provides the following effects and / or advantages:

[0019] In this application, the spraying part can spray a high-temperature curable and high-temperature resistant coating on the inner wall of the curing enclosure before welding. The instantaneous high temperature generated at the end of the stud during welding directly touches the sintering coating, which is sintered and cured into a ceramic layer without additional sintering processes.

[0020] The mounting disk and spraying rollers provided in this application can be inserted into the inner wall of the curing enclosure and sprayed, so as to thinly spray the sintering coating on the inner wall of the curing enclosure for subsequent sintering with the high temperature generated during the welding process of the stud.

[0021] The sintering coating of this application includes hexagonal boron nitride, temporary binder, and solvent, which can form a solution of powdery hexagonal boron nitride to achieve the spraying effect and can adhere to the inner wall of the curing enclosure. Hexagonal boron nitride can undergo surface activation of BN particles at high temperature to form a ceramic-like structure, thus adhering to the surface of the molten pool and being easily detached from the curing enclosure.

[0028] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0029] Referring to Figures 1-4 , an intelligent welding device suitable for floor decks, comprising:

[0030] A welding torch 1, a clamping member 12 is provided at the bottom end of the welding torch 1, and a movable rod 11 for moving up and down is provided on the welding torch 1;

[0031] A curing enclosure 2 is provided at the bottom end of the movable rod 11. The curing enclosure 2 is directly below the clamping member 12. The curing enclosure 2 is of an annular structure. The curing enclosure 2 includes a sleeving portion 21 and an enclosing portion 22. The enclosing portion 22 is provided at the lower end of the sleeving portion 21. The diameter of the enclosing portion 22 is larger than that of the sleeving portion 21. The sleeving portion 21 is used for sleeving on the bottom of the corresponding stud 10, and the enclosing portion 22 is used for enclosing the bottom end of the stud 10 to form a casting cavity;

[0032] A spraying member 3. After the spraying member 3 moves towards the curing enclosure 2, the spraying member 3 is inserted into the curing enclosure 2 and brushes and sinters a coating on the inner ring of the curing enclosure 2. The spraying member 3 is connected to an external sintering coating source.

[0033] In this embodiment, the clamping member 12 is used to clamp the top end of the stud 10. The welding torch 1 is connected to the positive voltage through the clamping member 12, and the floor formwork is connected to the negative voltage, so as to apply voltage across the two ends of the stud 10. The bottom of the stud 10 can be conical or pointed, so that the working current generated by the voltage converges at the end of the stud 10, forming a high temperature to melt the end of the stud 10 and making the stud 10 generate molten metal. The above is the working principle of the existing welding torch 1, and specific details can refer to the prior art. Then, in this embodiment, the bottom of the stud 10 is fixed by the sleeving portion 21, and the enclosing portion 22 expands to form a casting cavity, which restricts the flow range of the molten metal, reduces spatter and improves the consistency of the weld shape. At the same time, through the spraying member 3, a coating that can be cured after high temperature and is resistant to high temperature can be sprayed on the inner wall of the curing enclosure 2 before welding. During welding, the instantaneous high temperature generated at the end of the stud 10 directly touches and burns the sintering coating to sinter and cure into a ceramic layer, without the need for an additional sintering process.

[0034] Further, the spraying member 3 includes a mounting disk 31. On the bottom surface of the mounting disk 31, a plurality of downwardly directed spraying rollers 32 are arranged along the axial direction of the mounting disk 31. The spraying rollers are provided with a plurality of through holes, and the spraying rollers 32 communicate with corresponding feed pipes, and the feed pipes are connected to the sintering coating source.

[0035] Further, the mounting disk 31 is provided with transmission teeth on its outer periphery, and the transmission teeth are engaged with a corresponding rotating mechanism 33, and the rotating mechanism 33 drives the mounting disk 31 to rotate by a certain angle.

[0036] In this embodiment, the spraying member 3 includes a plurality of downwardly directed spraying rollers 32. The through holes provided in the spraying rollers can spray the sintering coating towards the inner wall of the enclosing portion 22, so that the sintering coating is actively output and adheres to the inner wall of the enclosing portion 22, forming a thin layer of coating. The plurality of spraying rollers 32 are circumferentially distributed along the mounting disk 31. With the cooperation of the rotational drive, the inner wall of the enclosure can be covered without dead angles of 360°, avoiding local accumulation or missed coating in traditional fixed brushing.

[0037] Specifically, the mounting disk 31 and the spraying rollers 32 can be arranged as hollow structures, and the mounting disk 31 and the spraying rollers 32 communicate with each other. Among them, the mounting disk 31 communicates with the feed pipe, and the aperture of the through hole is small, so as to be able to spray the sintering coating conveyed into the spraying rollers 32. And, the rotating mechanism 33 only needs to drive the mounting disk 31 to rotate by the corresponding interval angle between two adjacent spraying rollers 32, and preferably can rotate reciprocally to prevent the feed pipe from winding around other components.

[0038] Further, the spraying member 3 is sleeved on the movable rod 11, and the movable rod 11 is provided with a driving cylinder 4 for driving the spraying member 3 to move up and down.

[0039] Since the spraying member 3 can move up and down along the movable rod 11, and at the same time, the driving cylinder 4 drives the spraying member 3 to move up and down. After moving downward, the spraying member 3 can be inserted into the curing enclosure 2 for spraying work. After moving downward, the spraying member 3 is away from the curing enclosure 2 to prevent the high temperature generated during the welding process from damaging the spraying member 3.

[0040] Furthermore, the sintering coating is composed of hexagonal boron nitride, a temporary binder, and a solvent.

[0041] Furthermore, the temporary binder is polyvinyl alcohol, and the solvent is water.

[0042] Specifically, since the high temperature duration of the arc welding is short (<10 seconds), but the local temperature is extremely high (up to over 1500 °C near the molten pool), the hexagonal boron nitride set in this embodiment can activate the surface of BN particles at high temperature. The high temperature promotes the migration of surface atoms of BN particles, forming a ceramic-like structure on the inner wall of the curing enclosure 2 and covering the liquid generated after the stud 10 melts, restricting the shape and flow direction of the liquid generated after the stud 10 melts.

[0043] The temporary binder polyvinyl alcohol has the effect of improving the adhesion of hexagonal boron nitride to the inner wall of the curing enclosure 2. At the same time, the temporary binder polyvinyl alcohol has the characteristic of decomposing at high temperature. The heat generated after the stud 10 melts causes the temporary binder polyvinyl alcohol to decompose, generating tiny pores during the sintering of hexagonal boron nitride. The molten metal generated after the stud 10 melts may penetrate into the coating gaps, enhancing the interfacial bonding between the BN layer and the metal through the wetting effect. Through the high temperature resistance, lubricity, and thermal barrier effect of the BN coating, the shape of the molten pool and the solidification process are controlled. Even if the sintering coating is not completely sintered, it can still help the welding area generated at the bottom of the stud 10 to separate from the curing enclosure 2.

[0044] Moreover, after the temporary binder polyvinyl alcohol decomposes at high temperature, the molten metal generated after the stud 10 melts can penetrate into the coating gaps, enhancing the interfacial bonding between the BN layer and the metal through the wetting effect. It helps the BN layer generated after the sintering coating cures to adhere to the metal surface.

[0045] Preferably, when spraying the sintering coating as described above, the coating thickness is controlled within 30 - 100 μm, which can reduce the energy and time required for sintering, and at the same time ensure the functionality of the sintering coating to be cured by heat.

[0046] Furthermore, a grid-like groove 23 is provided on the inner circle of the enclosure portion 22.

[0047] In this embodiment, the grid-like grooves 23 can increase the inner wall surface area, enabling the sprayed boron nitride slurry to embed inside the grooves 23. After sintering, the ceramic layer and the enclosure base form a mechanical interlock, so that the surface of the sintered ceramic layer also has the grid-like groove 23 structure, increasing the heat dissipation area of the inner wall of the enclosure part 22, accelerating the solidification of the molten pool, and reducing the range of the heat affected zone (HAZ) of the base material. It is particularly suitable for the welding of thin-sheet floor bearing plates, preventing phenomena such as slow heat dissipation of the molten pool, bubbles, and cracks.

[0048] Further, the welding torch 1 is provided with a locking member 5 for locking the movable rod 11.

[0049] When the welding torch 1 is working, the curing enclosure 2 needs to be closely attached to the upper surface of the floor bearing plate at the bottom, so as to flatten the floor bearing plate and prevent the floor bearing plate from warping. Therefore, the movable rod 11 is locked by the locking member 5 to prevent the movable rod 11 from moving up and down and thus being unable to press the floor bearing plate; when inserting the stud 10 into the clamping member 12, the locking member 5 can be loosened to drive the movable rod 11 downward to create space for the insertion of the stud 10.
