Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a steel structure production line. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be carried out in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding.

[0003] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. During the production process, steel components are usually connected by welding. For example, a long steel plate is placed vertically and centered on another long steel plate, and then a T-shaped steel component is made by welding. At present, most steel structure welding production lines are used for automatic welding.

[0004] When welding, the existing steel structure welding production line usually needs to adjust the position of the welding head according to the thickness of the steel plate to ensure that the welding head can be aligned with the weld. This method of use is cumbersome and inconvenient to use. It is also easy to cause crooked welding due to misalignment of the weld. After welding is completed, in order to prevent rust at the weld, anti-rust oil needs to be applied manually, which consumes manpower. For this reason, we propose a steel structure production line to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The support assemblies are used to support steel components. The support assemblies include a support shaft 2. A support roller 3 and two support seats 4 are rotatably arranged on the outer periphery of the support shaft 2. The support seat 4 is fixed on the upper side of the base plate 1. The support roller 3 is located in the middle position above the base plate 1. During use, when welding work is required, a steel component needs to be placed on multiple support rollers 3 first. The support roller 3 is a rotatable structure, so as not to affect the translation of the steel component, and the support roller 3 can support the steel component.

[0038] like Figure 2 , Fig.11As shown, a centering positioning component is provided on the upper side of the base plate 1, and the centering positioning component is used to center the steel member, specifically: the centering positioning component is used to center the steel member in a horizontal state below, the centering positioning component includes a U-shaped adjustable frame 5, and intermediate holding components are provided on both ends of the U-shaped adjustable frame 5. The feeding component, the automatic seam welding component, the oiling component, and the oil supply component are located between the two intermediate holding components. The intermediate holding component includes two centering slides 6, and the centering slide 6 is a T-shaped structure. The centering slide 6 slides on the upper side of the base plate 1, and a centering frame 7 is fixedly provided on the upper side of the centering slide 6. Two centering wheels 8 are rotatably provided on the upper side of the centering frame 7. A centering rack 9 is fixedly provided on the side of the centering slide 6 close to each other, and a centering gear 10 is rotatably provided on the upper side of the base plate 1. The centering rack 9 is connected to the centering gear 10 through meshing transmission. A threaded hole is provided on the upper side of the centering slide 6, and the inner side of the threaded hole passes through A locking bolt 11 is provided through a threaded connection, and a centering slide 6 is fixed on one end of the U-shaped adjustable frame 5. The lower end of the locking bolt 11 contacts the upper side of the base plate 1. When welding work is required and the steel component is placed on the supporting roller 3, the position of the centering wheel 8 needs to be adjusted according to the width of the steel component. When adjusting the centering wheel 8, it is necessary to loosen the locking bolt 11 first, and then slide and adjust the centering slide 6 to adjust the position of the centering wheel 8. After the adjustment is completed, tighten the locking bolt 11 to lock it. During the adjustment, the positions of multiple centering wheels 8 can be adjusted at the same time through the U-shaped adjustable frame 5, so as to facilitate adjustment. At this time, the centering wheel 8 can position the steel component, so that the steel component can be restricted between the centering wheels 8 on both sides, and the lower steel component can be in the upper middle position of the base plate 1, which can prevent the steel component from running off during welding, thereby ensuring welding accuracy.

[0039] like Figure 6 , Fig.12 , Fig.13As shown, a feeding assembly is provided on the upper side of the base plate 1, and the feeding assembly is used to feed the steel member. The feeding assembly includes a synchronous moving assembly, a conveying drive assembly, a connecting transmission assembly and two adaptive clamping assemblies. The adaptive clamping assembly is used to clamp the steel member. The adaptive clamping assembly includes a hexagonal shaft 19 and two clamping main frames 12. The clamping main frames 12 are of a J-shaped structure. A tension spring 25 is fixed between the two clamping main frames 12. The clamping main frames 12 slide on the upper side of the base plate 1. A lifting plate 13 is slidingly provided on the outer periphery of the clamping main frames 12. A lower pressure roller 14 is rotatably provided on one side of the lifting plate 13. A through hole is provided on the upper side of the clamping main frame 12. A vertical roller 15 is rotatably provided on the inner side of the through hole. A through hole is provided on one side of the clamping main frame 12. An active roller 16 is rotatably arranged inside the through hole, and the lower pressure roller 14 is parallel to the active roller 16. When the steel member is placed on the supporting roller 3 and the active roller 16, it is in a horizontal state. A spring 17 is fixed between the upper side of the lifting plate 13 and the lower side of the top of the clamping main frame 12. During welding, it is necessary to place the steel member below between the active roller 16 and the lower pressure roller 14. At this time, the lower pressure roller 14 will be clamped between the active roller 16 and the lower pressure roller 14 due to the tension of the spring 17. At the same time, it is necessary to place the upper steel member between the two vertical rollers 15. At this time, the two vertical rollers 15 will clamp the steel member due to the tension of the tension spring 25. Then the active roller 16 is rotated, which can make the steel member below automatically translate. A hexagonal groove is provided at one end of each active roller 16 close to each other, and a hexagonal shaft 19 slides on the inner side of the hexagonal groove. One active roller 16 drives another active roller 16 to rotate through the hexagonal shaft 19. A driving wheel 20 is fixed on the outer periphery of the hexagonal shaft 19. When the active roller 16 rotates, the driving wheel 20 will also rotate, thereby improving the transmission force. Even if a wider steel component is transported, it can be transported stably. An anti-skid sleeve 18 is fixed on the outer periphery of the active wheel 20, the lower pressure roller 14, the vertical roller 15 and the active roller 16. The anti-skid sleeve 18 can play an anti-skid role, further improving the stable transportation capacity. A connecting shaft 21 is rotatably provided on the upper side of the clamping main frame 12, and two bearing seats are rotatably provided on the outer periphery of the connecting shaft 21. The bearing seats are fixed on The upper side of the clamping main frame 12 is connected to the outer periphery of the connecting shaft 21 and the outer periphery of the vertical roller 15 through a bevel gear transmission, and the outer periphery of the connecting shaft 21 and the outer periphery of the active roller 16 are connected through a belt and a pulley transmission. The thickest diameters of the active wheel 20, the active roller 16, the lower pressure roller 14 and the vertical roller 15 are the same. When the active roller 16 rotates, the rotation speed of the active roller 16 and the vertical roller 15 is the same. When the active roller 16 rotates, the vertical roller 15 can be driven to rotate through the connecting shaft 21, and the rotation speed of the active roller 16 and the vertical roller 15 is the same, so that the upper steel structure can move with the lower steel structure, and the moving speed is the same, so that automatic feeding and adaptive adjustment can be realized, and it has high versatility.

[0040] like Figure 6As shown, the feeding assembly is used to center the steel member, specifically: the feeding assembly is used to center the steel member in the vertical state above, the synchronous moving assembly is arranged between an adaptive clamping assembly and the base plate 1, the synchronous moving assembly includes a synchronous gear 22, the synchronous gear 22 rotates on the upper side of the base plate 1, the centering gear 10 and the synchronous gear 22 rotate on the upper side of the base plate 1 through the rotating shaft, a synchronous rod 23 is fixedly provided on the side where the two clamping main frames 12 are close to each other, a synchronous rack 24 is fixedly provided on the side where the synchronous rod 23 is close to each other, the synchronous rack 24 is connected to the synchronous gear 22 through meshing transmission, an anti-collision hole is provided on one side of the clamping main frame 12, the synchronous rod 23, the synchronous rack 24 and the synchronous gear 22 can make the two clamping main frames 12 close to or move away from each other synchronously, so that the upper steel member can be located in the upper middle position of the lower steel member, the upper steel member can be accurately welded to the upper middle position of the lower steel member, and center welding can be achieved.

[0041] like Figure 4 , Figure 5 As shown, the conveying drive assembly is arranged on one side of an adaptive clamping assembly, and the conveying drive assembly includes a fixed frame 26, and the fixed frame 26 is fixed on one side of a clamping main frame 12. A motor 27 is fixed on the upper side of the fixed frame 26. The motor 27 is connected to an external power supply and a switch through a wire. The shaft end of the motor 27 is fixed on one end of an active roller 16. During welding work, when the steel component needs to be translated, the motor 27 needs to be turned on. When the motor 27 is started, it will drive the active roller 16 to rotate. When the active roller 16 rotates, it will drive another active roller 16 and the vertical roller 15 to rotate, so that automatic feeding can be performed.

[0042] like Figure 7 , Fig.13 As shown, an automatic butt welding assembly is provided between the two adaptive clamping assemblies.

The connecting frame 28 is located between the two adaptive clamping components, and the two ends of the connecting frame 28 are respectively fixed on one side of the lifting plate 13, and the synchronous wheels 29 are respectively fixed on the outer periphery of the active roller 16. The synchronous belt 30 is connected to the outer periphery of the synchronous wheel 29 for transmission. When the active roller 16 in one adaptive clamping component rotates, the active roller 16 in the other adaptive clamping component is driven to rotate through the two synchronous wheels 29 and the plurality of synchronous belts 30. Therefore, during welding, the steel component can be completely welded from beginning to end, and the steel component can completely leave the feeding component to achieve complete welding. The connecting frame 28 can connect the lifting plates 13 in the two adaptive clamping components, so that the four clamping main frames 12 can move synchronously, and the welding head 31, the lifting plate 13 and the connecting frame 28 can only be lowered after the steel component completely leaves the feeding component, thereby ensuring complete welding.

A flexible contact ring 39 is fixedly provided on the outer periphery of the L-shaped driving ring 38. A plurality of anti-slip grooves are provided on the outer periphery of the flexible contact ring 39. The flexible contact ring 39 has a plurality of anti-slip grooves. 9 needs to be attached to the upper steel structure. When the steel structure moves horizontally, the flexible contact ring 39, the L-shaped drive ring 38, the oiling plate 36 and the annular oiling brush 37 can be driven to rotate. A coating block 40 is fixedly arranged on the upper side of the support frame 34. A semicircular coating groove is arranged on one side of the coating block 40. The semicircular coating groove matches the annular oiling brush 37. The annular oiling brush 37 slides in the semicircular coating groove. An oil inlet hole is arranged on the upper side of the coating block 40. The oil inlet hole is connected to the semicircular coating groove. The inner side of the oil inlet hole An oil inlet hopper 41 is fixedly provided, and the annular oiling brush 37 will slide through the semicircular coating groove when it rotates, and the anti-rust oil entering the oil inlet hopper 41 will enter the semicircular coating groove.

At the same time, when the annular oiling brush 37 rotates, the anti-rust oil on the annular oiling brush 37 can be evenly applied to the weld, thereby achieving automatic and uniform oiling.

[0045] like Figure 3 , Figures 8 to 10 , Fig.13As shown, an oil supply assembly is provided on the upper side of the oiling assembly, and the oil supply assembly is used to provide anti-rust oil for the oiling assembly. The automatic seam welding assembly, the oiling assembly, and the oil supply assembly are located between the two adaptive clamping assemblies.

When feeding, the driving roller 16 will rotate. When the driving roller 16 rotates, it will drive the oil supply shaft 46 and the lower oil wheel 45 to rotate through the belt and the pulley. When the lower oil wheel 45 rotates, a small amount of anti-rust oil in the oil tank 47 will be transferred to the bottom of the flexible sealing block 44, and then discharged through the oil drip hole 43. The oil discharged from the oil drip hole 43 will drip into the oil inlet hopper 41, thereby realizing automatic and continuous quantitative oil supply.
