Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and specifically to a flame arrester structure. Background Technology

[0002] In brazing equipment for products such as copper and aluminum, the traditional flame plate mechanism consists of a main stainless steel tube bent into a circular or semi-circular ring 31, with varying numbers of copper connecting tubes 32 connected below as needed. A standard air welding nozzle 33 is then installed at the end of each copper connecting tube 32 (see...). Figure 1 For example, the patent specification with publication number CN205166108U discloses an adjustable flame burner mechanism assembly, wherein the welding nozzle is connected to the flame nozzle tube via a flame nozzle connector, and the welding nozzle can rotate on the flame nozzle tube.

[0003] In the use of traditional fire grille mechanisms, when there is a collision caused by human error or improper equipment adjustment, the copper connecting pipes and other components are severely deformed. Manually adjusting them with pliers is time-consuming and laborious, and requires a high level of skill from the adjuster. General operators do not have this ability. Therefore, it is necessary to design a fire grille mechanism that is strong enough, not easily deformed after fixing, and easy to adjust. Utility Model Content

[0004] In view of the above-mentioned technical problems and the shortcomings of the field, this utility model provides a fire grid structure that ensures strength through an integrated structural design and will not deform upon impact, thus eliminating the need for cumbersome debugging processes and improving welding efficiency and welding stability.

[0005] The specific technical solution is as follows: A fire grill structure, including a fire grill mechanism; The fire grid mechanism includes a rigid main ventilation pipe, on which a rigid first ventilation branch pipe and a rigid second ventilation branch pipe are fixedly connected. A first gas pipe and a second gas pipe are respectively connected to the first ventilation branch pipe and the second ventilation branch pipe. The first gas pipe and the second gas pipe are respectively connected to a rigid first gas distribution block and a rigid second gas distribution block. The first gas distribution block and the second gas distribution block are each independently connected to one or more burners. The first air distribution block and the second air distribution block are respectively fixedly connected to the first air supply branch pipe and the second air supply branch pipe through the first rigid member and the second rigid member.

[0006] When the above-mentioned burner structure is in use, a mixture of gas containing fuel gas and oxidizing gas is introduced into the main ventilation pipe. The mixture enters the first ventilation branch pipe and the second ventilation branch pipe through the main ventilation pipe, and then enters the first gas distribution block and the second gas distribution block through the first gas pipe and the second gas pipe respectively. Finally, it forms a flame through the burner nozzle.

[0007] In the burner structure of this utility model: the main vent pipe is fixedly connected to the first vent branch pipe, the first rigid component and the first gas distribution block in sequence, and these components are all rigid structures, which ensures the stability of the first gas passage and the corresponding burner position; the main vent pipe is fixedly connected to the second vent branch pipe, the second rigid component and the second gas distribution block in sequence, and these components are all rigid structures, which ensures the stability of the second gas passage and the corresponding burner position.

[0008] In some embodiments, the first rigid member and the second rigid member of the fire grill structure are each independently provided with a hollow structure, which can achieve the purpose of weight reduction. Appropriately reducing the weight can further ensure the stability of the overall structure of the fire grill mechanism.

[0009] In some embodiments, the fire grid structure has a first air hole and a second air hole respectively provided in the first air distribution block and the second air distribution block. The first air hole and the second air hole are connected by a third air pipe. This design forms a direct gas passage between the first air distribution block and the second air distribution block, which is conducive to the uniform distribution of gas in the first air distribution block and the second air distribution block and ensures the uniformity of the flames emitted by the corresponding burners.

[0010] In some embodiments, the main ventilation pipe, the first ventilation branch pipe, and the second ventilation branch pipe of the fire vent structure are all stainless steel pipes, and their internal spaces are interconnected.

[0011] In some embodiments, the fire grid structure has a first guide groove and a second guide groove respectively provided in the first gas distribution block and the second gas distribution block; The first rigid component is connected to the first guide groove, and the position of the first air distribution block fixedly connected to the first rigid component is adjustable. The second rigid component is connected to the second guide groove, and the position of the second air distribution block fixedly connected to the second rigid component is adjustable.

[0012] In some embodiments, the fire duct structure has a first gas pipe and a second gas pipe, both of which are copper pipes with flexible and bendable characteristics.

[0013] In some embodiments, the flame grid structure further includes a swing mechanism, which drives the flame grid mechanism to swing, thereby expanding the welding area during welding operations, ensuring uniform heating of the welding point and its surrounding area, and guaranteeing welding quality.

[0014] Furthermore, the swing mechanism may include a drive device, a wheel, a first connecting column, a connecting rod, a second connecting column, a mounting plate, and a slide rail; The output end of the drive unit is connected to the wheel. The first connecting post is eccentrically set on the wheel. The connecting rod connects the first connecting post and the second connecting post. The second connecting post is set on the mounting plate. The main ventilation pipe is fixed on the mounting plate. The mounting plate is set on the slide rail and can move back and forth along the slide rail. The drive device is used to drive the rotating wheel to rotate, which in turn drives the first connecting column to move in a circular motion. This causes the second connecting column, the mounting plate, and the main ventilation pipe to move back and forth along the slide rail via the connecting rod, thus realizing the swing of the fire grill mechanism.

[0015] Furthermore, the slide rails are aligned radially with the main ventilation pipe; The swing mechanism is used to drive the fire exhaust mechanism to swing radially along the main ventilation pipe.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. The fire grid mechanism in the fire grid structure of this utility model will not deform when it is hit, which can save the tedious debugging process and improve welding efficiency and welding stability.

[0017] 2. The fire plate structure of this utility model can adjust the position of the fire plate mechanism through the swing mechanism, so as to realize the swing of the fire plate mechanism during the welding process, thereby expanding the welding area when the fire plate mechanism is performing welding work, so that the welding point and its surrounding area are heated evenly, and the welding quality is guaranteed.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Example 1:

[0024] See Figure 2 A fire grill structure, comprising a rigid fire grill mechanism.

[0025] The burner mechanism includes a rigid main vent 1. One end of the main vent 1 is open, and the other end is sealed. The open end of the main vent 1 can be used to receive a mixture containing fuel gas and oxidizing gas. A rigid first vent branch pipe 2 and a rigid second vent branch pipe 3 are fixedly connected to the main vent 1, wherein the second vent branch pipe 3 is closer to the sealed end of the main vent 1 than the first vent branch pipe 2, and the first vent branch pipe 2 and the second vent branch pipe 3 are located on the same side of the main vent 1. In this embodiment, the main vent 1, the first vent branch pipe 2, and the second vent branch pipe 3 are all stainless steel pipes with interconnected internal spaces. The lower ends of the first vent branch pipe 2 and the second vent branch pipe 3 are respectively connected to one end of a first gas pipe 4 and a second gas pipe 5. The other ends of the first gas pipe 4 and the second gas pipe 5 are respectively connected to a rigid first gas distribution block 6 and a rigid second gas distribution block 7. One or more burners 8 are independently connected to the inner sides of the first gas distribution block 6 and the second gas distribution block 7, and the burners 8 connected to the first gas distribution block 6 and the second gas distribution block 7 are arranged opposite each other. The first air distribution block 6 and the second air distribution block 7 are respectively fixedly connected to the first ventilation branch pipe 2 and the second ventilation branch pipe 3 above by the first rigid member 9 and the second rigid member 10.

[0026] In this embodiment, when the burner structure is in use, a mixture of gas containing fuel gas and combustion-supporting gas is introduced into the open end of the main ventilation pipe 1. The mixture enters the first ventilation branch pipe 2 and the second ventilation branch pipe 3 through the main ventilation pipe 1, and then enters the first gas distribution block 6 and the second gas distribution block 7 through the first gas pipe 4 and the second gas pipe 5 respectively. Finally, a flame is formed through the burner nozzle 8.

[0027] In the burner mechanism of this embodiment: the main ventilation pipe 1 is sequentially and fixedly connected to the first ventilation branch pipe 2, the first rigid component 9, and the first gas distribution block 6, and these components are all rigid structures, ensuring the stability of the first gas passage and the corresponding burner position; the main ventilation pipe 1 is sequentially and fixedly connected to the second ventilation branch pipe 3, the second rigid component 10, and the second gas distribution block 7, and these components are all rigid structures, ensuring the stability of the second gas passage and the corresponding burner position. The design of the above structure ensures the strength of the burner mechanism, preventing deformation upon impact, eliminating the need for tedious debugging processes, and improving welding efficiency and welding stability.

[0028] like Figure 2 As shown, in the fire vent mechanism of this embodiment, the first rigid member 9 and the second rigid member 10 are respectively provided with hollow structures, which can achieve the purpose of weight reduction, so as to prevent one side of the ventilation main pipe 1 from being too heavy. Appropriately reducing the weight can further ensure the stability of the overall structure of the fire vent mechanism.

[0029] like Figure 2As shown, in the burner mechanism of this embodiment, the first gas distribution block 6 and the second gas distribution block 7 are respectively provided with a first gas hole 11 and a second gas hole, and the first gas hole 11 and the second gas hole are connected by a third gas pipe 12. In order to avoid interference with the workpiece and the welding flame generated by the burner, in this embodiment, the third gas pipe 12 is arranged along the outside of the first gas distribution block 6, the first rigid member 9, the first ventilation branch pipe 2, and the ventilation main pipe 1.

[0030] In the fire-grille mechanism of this embodiment, the first gas distribution block 6 and the second gas distribution block 7 are respectively provided with a first guide groove and a second guide groove. The first rigid member 9 is connected to the first guide groove, and the position of the first gas distribution block 6 fixedly connected to the first rigid member 9 is adjustable, that is, the first gas distribution block 6 can adjust its vertical position on the first rigid member 9 through the first guide groove. The second rigid member 10 is connected to the second guide groove, and the position of the second gas distribution block 7 fixedly connected to the second rigid member 10 is adjustable, that is, the second gas distribution block 7 can adjust its vertical position on the second rigid member 10 through the second guide groove. In this embodiment, the first gas pipe 4 and the second gas pipe 5 can both be copper pipes. Copper pipes have flexible and bendable characteristics, and can be bent accordingly when adjusting the vertical position of the first gas distribution block 6 and the second gas distribution block 7.

[0031] Example 2:

[0032] See Figure 3 , Figure 4 The fire grill structure in this embodiment also includes a swing mechanism based on embodiment 1.

[0033] The swing mechanism includes a drive device 13, a rotating wheel 14, a first connecting column 15, a connecting rod 16, a second connecting column 17, a mounting plate 18, and a slide rail 19. In this embodiment, the drive device 13 may specifically be a motor, etc.

[0034] The rotating wheel 14 is connected to the output end of the drive device 13. The first connecting post 15 is eccentrically set on the rotating wheel 14. The connecting rod 16 connects the first connecting post 15 and the second connecting post 17. The second connecting post 17 is set on the mounting plate 18. The venting main pipe 1 is fixed on the mounting plate 18. The mounting plate 18 is set on the slide rail 19 and can move back and forth along the slide rail 19. The direction of the slide rail 19 is consistent with the horizontal radial direction of the venting main pipe 1.

[0035] The drive device 13 is used to drive the rotating wheel 14 to rotate, thereby driving the first connecting column 15 to move in a circular motion. This causes the second connecting column 17, the mounting plate 18, and the venting main pipe 1 to move back and forth along the slide rail 19 via the connecting rod 16, thus realizing the horizontal radial swing of the fire vent mechanism along the venting main pipe 1.

[0036] The flame grid structure in this embodiment can adjust the position of the flame grid mechanism through a swing mechanism, so as to realize the swing of the flame grid mechanism during the welding process, thereby expanding the welding area when the flame grid mechanism is performing welding work, so that the welding point and its surrounding area are heated evenly, and the welding quality is guaranteed.
