Description

Technical Field

[0001] The utility model relates to the technical field of building material equipment, in particular to a steel bar welding device for autoclaved aerated concrete slabs. Background Art

[0002] Autoclaved aerated concrete slabs are a kind of lightweight and porous new type of green environmental protection building material, which takes cement, lime, silica sand, etc. as the main raw materials and is configured with different numbers of steel bar meshes treated with anti-corrosion according to the structural requirements. After high-temperature and high-pressure steam curing, autoclaved aerated concrete slabs with porous crystals are produced by reaction. Their density is smaller than that of general cementitious materials, and they have excellent fire resistance, fire prevention, sound insulation, heat insulation, heat preservation and other unparalleled properties. During its use and construction, the steel bar mesh needs to be welded.

[0003] A welded steel bar mesh is a mesh sheet in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and are perpendicular to each other, and all intersection points are welded together. It is often combined with concrete and applied in the construction field. Most current steel bar mesh welding equipment is equipped with a spot welder using the principle of resistance welding. A lower electrode is fixedly arranged on the frame, and a cylinder is used to drive the upper electrode to move down to press the contact points of the transverse bars and longitudinal bars, and then an electric current is applied to instantly melt the contact points of the transverse bars and longitudinal bars to achieve the welding of the welded steel bar mesh.

[0004] At present, in order to improve the welding efficiency of the steel bar welding device for autoclaved aerated concrete slabs, a progressive welding operation is usually adopted. After completing the welding operation between a group of transverse bars and multiple groups of longitudinal bars, the whole welded mesh is moved and the inclined setting of the feeding component is cooperated to let the transverse bars roll onto multiple groups of longitudinal bars for welding. However, after the transverse bars roll down, their landing points are likely to be offset as a whole due to different contact points at both ends of the transverse bars when they fall, resulting in local non-contact positions during welding by the spot welder and causing welding omission, thus reducing the stability of the overall structure of the welded mesh sheet. In order to position the transverse bars during the welding process between the transverse steel bars and multiple groups of longitudinal steel bars, we propose a steel bar welding device for autoclaved aerated concrete slabs.

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: a steel bar welding device for autoclaved aerated concrete slabs, including a frame 1. Mounting seats 2 are bolted to the front and rear sides of the upper end surface of the frame 1. A welding assembly is installed between the front and rear mounting seats 2. A transverse steel bar feeding assembly is installed on the right side of the upper end of the frame 1. Steel bar positioning assemblies are installed on the front and rear sides of the welding assembly. During use, the transverse steel bar feeding assembly feeds a group of transverse steel bars into the welding assembly, and then the steel bar positioning assemblies position the transverse steel bars to prevent the overall offset of the transverse bars, so as to avoid missing welding at local positions during welding by the welding assembly and improve the welding quality.

[0030] The welding assembly includes a mounting frame 4. The mounting frame 4 is fixedly installed between the front and rear mounting seats 2 by a plurality of bolts. A downward cylinder 5 is fixedly installed on the upper end surface of the mounting frame 4. The output end of the downward cylinder 5 is fixedly connected to a lifting frame 9. Panels 3 are bolted to the left and right sides of the lifting frame 9. A plurality of upper electrodes 10 are installed between the left and right panels 3. A plurality of lower electrodes 11 corresponding to the upper electrodes 10 are installed on the frame 1.

[0031] When using the welding assembly, the downward cylinder 5 drives the upper electrode 10 to move downward, and the upper electrode 10 cooperates with the lower electrode 11 to weld the contact part between the transverse steel bar and the longitudinal steel bar.

[0032] The steel bar positioning assembly includes a mounting plate 26. Fixing blocks 21 are installed on the left and right sides of the upper end surface of the mounting plate 26 by screws. A transmission rod 27 is installed on the fixing block 21. A sector gear 24 is fixedly connected to the transmission rod 27. A first positioning clamp plate 25 is integrally connected to the sector gear 24. The end of one of the transmission rods 27 is fixedly connected to a gear 19. Two toothed plates 18 are fixedly connected to the bottom of the panel 3. The toothed plates 18 are meshed with the gear 19. The two sector gears 24 are meshed with each other.

[0033] A connecting block is fixedly connected to the mounting plate 26. A rotating rod 23 is rotatably installed on the connecting block. A second positioning clamp plate 20 is fixedly sleeved on the rotating rod 23. A worm gear 22 is fixedly connected to the end of the rotating rod 23. A worm 28 is installed on one of the transmission rods 27. The worm 28 is meshed with the worm gear 22.

[0034] When the downward cylinder 5 drives the panel 3 to move downward, since the toothed plate 18 meshes with the gear 19 and the two sets of sector gears 24 mesh with each other, the first positioning clamping plates 25 on the left and right sides will rotate inward simultaneously. At this time, the two sets of first positioning clamping plates 25 will position the left and right positions of the horizontal steel bars. At the same time, since the worm 28 meshes with the worm gear 22, the second positioning clamping plate 20 will rotate towards the horizontal steel bar, and the second positioning clamping plates 20 on the front and rear sides will position the front and rear positions of the horizontal steel bar, thereby ensuring that the position of the horizontal steel bar does not shift.

[0035] The horizontal steel bar feeding assembly includes a feeding box 6. The bottom of the feeding box 6 is integrally connected with a cylindrical shell 17. The bottom of the cylindrical shell 17 is integrally connected with a discharge shell 13. A feeding motor 8 is fixedly installed on the front side of the cylindrical shell 17. The output end of the feeding motor 8 is fixedly connected with a feeding roller 16. The feeding roller 16 is rotatably installed inside the cylindrical shell 17, and a plurality of steel bar blanking grooves 15 are formed on the outer surface of the feeding roller 16.

[0036] The bottom of the feeding box 6 is fixedly connected with a support plate 7, and a plurality of guide frames 14 are fixedly connected to the left end surface of the support plate 7.

[0037] When using the horizontal steel bar feeding assembly, the feeding motor 8 works. The horizontal steel bars in the feeding box 6 will enter the steel bar blanking grooves 15. The feeding motor 8 drives the feeding roller 16 to rotate, and the horizontal steel bars will fall into the guide frames 14 through the discharge shell 13, and then fall below the upper electrode 10 under the action of their own gravity.

[0038] A plurality of heat dissipation fins are fixedly installed on the outer surface of the feeding motor 8, and the heat dissipation fins can facilitate the heat dissipation of the feeding motor 8.

[0039] A chute is provided inside the mounting seat 2. A sliding seat 12 is slidably assembled on the chute. The sliding seat 12 and the panel 3 are fixedly connected by a plurality of bolts. By the cooperation of the sliding seat 12 and the chute, the upper electrode 10 can move up and down stably.

[0040] A plurality of sliding rods are slidably penetrated through the upper end surface of the mounting frame 4, and the bottom ends of the sliding rods are fixedly connected to the upper end surface of the lifting frame 9.

[0041] Wear-resistant rubber layers are fixedly bonded to the inner sides of the first positioning clamping plates 25 and the second positioning clamping plates 20. The wear-resistant rubber layers can improve the wear resistance of the first positioning clamping plates 25 and the second positioning clamping plates 20.

[0042] Working principle: When in use, the feeding motor 8 works. The horizontal steel bars in the feeding box 6 will enter the steel bar blanking grooves 15. The feeding motor 8 drives the feeding roller 16 to rotate, and the horizontal steel bars will fall into the guide frames 14 through the discharge shell 13, and then fall below the upper electrode 10 under the action of their own gravity;

[0043] Subsequently, the downward cylinder 5 drives the upper electrode 10 to move downward. Since the toothed plate 18 meshes with the gear 19, and since the two sets of sector gears 24 mesh with each other, at this time, the first positioning clamping plates 25 on the left and right sides will rotate inward simultaneously. At this time, the two sets of first positioning clamping plates 25 will position the left and right sides of the transverse steel bar. At the same time, since the worm 28 meshes with the worm gear 22, the second positioning clamping plate 20 will rotate towards the transverse steel bar, and the second positioning clamping plates 20 on the front and rear sides will position the front and rear positions of the transverse steel bar, thereby ensuring that the position of the transverse steel bar does not shift. Finally, the upper electrode 10 and the lower electrode 11 cooperate to weld the contact between the transverse steel bar and the longitudinal steel bar.
