Description

Technical Field

[0001] This invention belongs to the field of door and window processing technology, and particularly relates to a metal door and window processing welding device. Background Technology

[0002] Welding equipment for metal door and window processing refers to equipment used to weld the components of metal doors and windows. Its main function is to connect metal materials together, increase the strength and stability of the door and window structure, and play a crucial role in the manufacturing process. It can improve the connection strength, sealing and stability of doors and windows, and ensure the quality and performance of doors and windows. Therefore, a welding equipment for metal door and window processing is needed.

[0003] Patent publication number CN222857108U discloses a welding device for processing metal doors and windows, comprising a base plate, an adjusting mechanism, an arc plate, a control module, and metal doors and windows. The base plate has two support plates, and the tops of the two support plates are provided with a common worktable. An arc plate is fixedly installed on the worktable, and two slide rails are provided on the arc plate. Each slide rail contains a pulley, and one end of each pulley is fixedly connected to a common housing. The housing is equipped with an adjusting mechanism, and the worktable is equipped with a control module. The adjusting mechanism is connected to the control module. This invention has the following advantages and effects: by coordinating the various components, welding the top and bottom of the metal doors and windows can be achieved without flipping them, improving convenience and processing efficiency. Furthermore, it has a simple structure and higher practicality.

[0004] Existing technologies, using components such as curved plates, enable welding of the top and bottom of metal doors and windows, but still have shortcomings: First, existing door and window welding equipment lacks adjustment components for extrusion welding of doors and windows with different shapes and angles, resulting in poor adaptability of the welding equipment and inability to perform welding operations on diverse doors and windows. Secondly, when welding doors and windows, it is often necessary to spray argon gas at the welding area to form a protective barrier and improve the welding strength. Argon gas itself has high value, and the sprayed argon gas can be recovered, purified and reused. However, the existing welding equipment lacks a structure for recovering argon gas, which leads to high welding costs. Finally, before welding doors and windows, the pipes required for welding are prone to not being able to fit tightly together when they are joined. Existing welding components lack grinding treatment on the pipe joint surfaces before welding, which can easily lead to weak welds during subsequent welding. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a metal door and window processing and welding device. Through the arrangement of components such as clamping discs, this invention can perform multi-angle extrusion and fixation of the pipes used for door and window welding, resulting in a tighter compression between the pipes and enabling the compression and fixation of pipes abutting at different angles. Through the arrangement of components such as U-shaped hollow plates, argon gas can be output to the welding area, protecting the welding area while also absorbing and storing the argon gas for subsequent purification and reuse.

Each elastic folding plate is inclined toward the slide table. A damping protrusion is fixedly provided at one end of each elastic folding plate. A limiting groove is provided on one side of each damping protrusion on the side wall of the first side plate and the clamping plate.

[0008] Optionally, a second extrusion plate is rotatably disposed inside both the first U-shaped hollow plate and the second U-shaped hollow plate. A diagonal brace is fixedly disposed on one side of each second extrusion plate on the inner sidewall of the first U-shaped hollow plate and the second U-shaped hollow plate. A first spring is connected between every two adjacent second extrusion plates and diagonal braces.

[0009] Optionally, an elongated hole is provided below the slide table on the upper end face of the worktable, and a sliding groove is provided on the inner side wall of the elongated hole. A sliding locking block is slidably engaged inside the sliding groove, and the sliding locking block is fixedly connected to the lower end face of the slide table.

[0010] Optionally, a first sliding support frame is fixedly connected to the lower end face of the workbench below the elongated hole, a second sliding support frame is slidably arranged inside the first sliding support frame, a base plate is slidably arranged inside the second sliding support frame, and a grinder is rotatably arranged on the upper end face of the base plate.

[0011] Optionally, the argon output component includes multiple jet heads disposed on one side wall of the first U-shaped hollow plate, the input port of each jet head being interconnected with the internal cavity of the first U-shaped hollow plate, and the first U-shaped hollow plate being interconnected with an external argon source.

[0012] Optionally, the argon gas collection and storage assembly includes multiple horn-shaped gas inlets disposed on one side wall of the second U-shaped hollow plate, each of the horn-shaped gas inlets being interconnected with the internal cavity of the second U-shaped hollow plate, and a gas storage tank being disposed on the lower end face of the workbench.

[0013] Optionally, the interior of the second U-shaped hollow plate is provided with multiple V-shaped filter plates, and a waste trough is provided between every two adjacent V-shaped filter plates.

[0014] Optionally, multiple support plates are fixedly provided on one side of each of the multiple V-shaped filter plates on the inner wall of the second U-shaped hollow plate, and each support plate is connected to its adjacent V-shaped filter plate by a second spring.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting up components such as clamping plate, clamping plate and second extrusion plate, the present invention can extrude and fix the pipes for welding doors and windows at multiple angles, which facilitates the subsequent welding of the pipes, makes the extrusion between the pipes tighter, improves the welding quality, and can also extrude and fix pipes that abut at different angles, thus improving the adaptability of the welding device. (2) By setting up components such as the first U-shaped hollow plate and the second U-shaped hollow plate, the present invention can output argon gas to the welding part, forming protection for the welding part, and can also absorb and store argon gas in the welding part, which is convenient for subsequent argon gas purification and secondary use. At the same time, during the argon gas collection process, the welding debris can be collected and stored to prevent the high-temperature welding metal particles from splashing and causing burns to the operators. (3) By setting up components such as an extension plate, a rotating plate and a grinding machine, the present invention can grind the contact surface of the welded pipes before welding the doors and windows, thereby improving the tightness of the contact between the pipes during welding and thus improving the welding strength.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example 1:

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, a metal door and window processing welding device includes a worktable 10. A welding robotic arm 47 is mounted on the upper surface of the worktable 10. The welding robotic arm 47 is a multi-axis welding robot capable of performing rapid welding at multiple angles, which is existing technology. Two circular grooves 11 are provided on one side of the welding robotic arm 47 on the upper surface of the worktable 10. Each circular groove 11 has a clamping plate 12 rotatably mounted inside it to prevent the pipes used for welding doors and windows. An annular limiting groove 48 is provided on the inner circular surface of each circular groove 11. A toothed ring 49 is fixedly mounted on the outer circular surface of each clamping plate 12. Each toothed ring 49 rotatably engages with its external annular limiting groove 48. The arrangement of the annular limiting groove 48 and the toothed ring 49... The rotation of the clamping disk 12 within the circular groove 11 is limited to prevent it from detaching from the groove 11. Each toothed ring 49 has a transmission gear 50 meshing and rotating on one side inside the worktable 10. Below each transmission gear 50, on the lower end face of the worktable 10, is a first motor that drives the transmission gear 50 to rotate. The first motor is a common servo motor equipped with a control system for rotation angle detection and fine-tuning, which is existing technology and will not be elaborated on in this application. The output end of the first motor drives the transmission gear 50 to rotate, thereby driving the toothed ring 49 and the clamping disk 12 to rotate, thus adjusting the angle of the pipe clamped on the upper end face of the clamping disk 12.

[0021] It should be noted that when the two clamping discs 12 rotate to adjust the angle of the pipes clamped and fixed on their upper surfaces, the two first motors rotate synchronously and in opposite directions to ensure that the welding surfaces of the two pipes can be tightly joined.

[0022] Furthermore, such as Figure 1 and Figure 4 As shown, in order to tightly clamp and fix the pipe placed on the upper end face of the clamping plate 12, two first side plates 13 are provided on the upper end face of each clamping plate 12. A clamping plate 14 is slidably arranged between every two adjacent first side plates 13. A first push cylinder is fixedly arranged on the outer side wall of each outer first side plate 13. The output end of the first push cylinder passes through the first side plate 13 and is fixedly connected to one side wall of the clamping plate 14. When welding doors and windows, the pipe to be welded needs to be placed between the adjacent first side plates 13 and the clamping plate 14. The output end of the first push cylinder drives the clamping plate 14 to move horizontally, which cooperates with the first side plate 13 to form a clamping and fixing of the pipe between the first side plate 13 and the clamping plate 14.

[0023] Furthermore, such as Figure 1 and Figure 8As shown, to improve the stability of the pipe clamping between the first side plate 13 and the clamping plate 14, multiple elastic folding plates 15 are provided on the sidewalls of each clamping plate 14 and the opposite sidewall of the first side plate 13. The elastic folding plates 15 are made of elastic metal material, and each elastic folding plate 15 is inclined towards the slide table 28. A damping protrusion 16 is fixedly provided at one end of each elastic folding plate 15. The damping protrusion 16 is made of damping rubber, and a limiting groove 17 is provided on one side of each damping protrusion 16 on the sidewall of the first side plate 13 and the clamping plate 14. Every two adjacent damping protrusions 16 and... The limiting grooves 17 interlock with each other. When the clamping plate 14 moves horizontally to clamp the pipe in conjunction with the first side plate 13 on one side, the pipe is pressed against the side walls of the first side plate 13 and the clamping plate 14 by multiple elastic folding plates 15 on both sides. This causes each elastic folding plate 15 to rotate the damping protrusion 16 at one end and engage with the limiting groove 17 on one side. At this time, the limiting groove 17 forms a locking and limiting action on the damping protrusion 16. The multiple damping protrusions 16 will deform to different degrees under continuous compression and fit tightly against the pipe over a large area, thus forming a clamping and fixing effect. In this application, the damping force between the damping protrusion 16 and the pipe forms a damping limit for the horizontal sliding of the pipe between the first side plate 13 and the clamping plate 14.

[0024] It should be noted that when the pipes on both sides of the welded area are elastically compressed, each pipe will be subjected to a compressive force opposite to the tilt direction of the elastic folding plate 15. At this time, multiple elastic folding plates 15 form a supporting force on the pipes in the opposite direction, further ensuring the stable clamping of the pipes between the first side plate 13 and the clamping plate 14.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 10 As shown, in order to further improve the tight contact between the pipes during welding, an elongated hole 22 is provided on the upper surface of the workbench 10 between the two clamping discs 12. A sliding groove 27 is provided inside the elongated hole 22, and a sliding snap block 29 is slidably arranged inside the sliding groove 27. A slide table 28 is slidably arranged above the sliding snap block 29 on the upper surface of the workbench 10. The slide table 28 and the sliding snap block 29 are fixedly connected. Second side plates 30 are fixedly arranged on both sides of the elongated hole 22 on the upper surface of the slide table 28. A first U-shaped hollow plate 31 is elastically slidably arranged on one side of one of the second side plates 30, and a second U-shaped hollow plate 32 is elastically slidably arranged on one side of the other second side plate 30. Under the horizontal pushing action of the slide table 28 and the second side plate 30, the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32 can form a semi-annular enclosure around the pipe on one side.

[0026] A second extrusion plate 33 is rotatably mounted inside both the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32. A diagonal brace 34 is fixedly mounted on one side of each second extrusion plate 33 on the inner wall of the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32. A first spring 35 connects every two adjacent second extrusion plates 33 and diagonal braces 34. A second push cylinder is mounted on one side of the sliding latching block 29 on the outer wall of the worktable 10. The output end of the second push cylinder passes through the worktable 10 and is fixedly connected to one side of the sliding latching block 29. The second push cylinder is a common electric push cylinder. After clamping and adjusting the angle of the pipe, the welding of the pipe... When the joints are in abutting state, the output end of the second push cylinder drives the sliding snap block 29 and slide table 28 to slide towards the pipe. At this time, the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32 slide horizontally with the slide table 28 and the second side plate 30 until the inclined sidewalls of the two second extrusion plates 33 are tightly abutting against the outer sidewalls of their adjacent pipes. Under the elastic tension of the first spring 35, an elastic extrusion is formed on the second extrusion plate 33 towards the pipe. The two second extrusion plates 33 are at an angle to extrude the two pipes, making the welding surfaces between the pipes more tightly abutted and improving the subsequent welding accuracy.

[0027] Furthermore, such as Figure 5 and Figure 11 As shown, a sliding rod 51 is fixedly installed on one side wall of the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32. Each sliding rod 51 is slidably limited connected to the second side plate 30 on its side. A third spring 52 is installed on the outside of each sliding rod 51. The sliding rod 51 and the third spring 52 provide elastic support to one side wall of the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32, so that when the first U-shaped hollow plate 31 and the second U-shaped hollow plate 32 drive the second extrusion plate 33 to clamp the pipe, there is a larger elastic buffer distance, which further improves the buffering capacity of the second extrusion plate 33 when elastically extruding one side of the pipe.

[0028] Furthermore, such as Figure 4 and Figure 9As shown, to improve welding quality, argon gas protection is required at the welding area. Therefore, multiple jet nozzles 36 are installed on one U-shaped sidewall of the first U-shaped hollow plate 31. The input port of each jet nozzle 36 is connected to the internal cavity of the first U-shaped hollow plate 31. An air inlet port 37, which is connected to the internal cavity of the first U-shaped hollow plate 31, is installed on the other U-shaped sidewall of the first U-shaped hollow plate 31. The air inlet port 37 is connected to an external argon gas source, through which argon gas is continuously supplied to the first U-shaped hollow plate. Argon gas is filled into the interior of the first U-shaped hollow plate 31. The argon gas entering the interior of the first U-shaped hollow plate 31 is ejected through multiple jet nozzles 36 to form argon gas protection for the welding area. A vision probe 38 is provided on the side wall of the first U-shaped hollow plate 31 between every two adjacent jet nozzles 36. The vision probe 38 is a high-definition monitoring probe that can capture the welding area and control the jet nozzles 36 at the welding area to eject argon gas, while the other jet nozzles 36 remain sealed. This ensures sufficient argon gas during welding while effectively saving some argon gas.

[0029] Furthermore, such as Figure 1 and Figure 7 As shown, since argon gas itself is expensive, it can be recycled, purified, and reused to save welding costs. Therefore, multiple horn-shaped gas inlets 43 are set on one side of the U-shaped sidewall of the second U-shaped hollow plate 32. The inlet ports of the multiple horn-shaped gas inlets 43 correspond to the gas outlets of the multiple jet heads 36 on the same side. Each horn-shaped gas inlet 43 is connected to the internal cavity of the second U-shaped hollow plate 32. A gas storage tank 44 is set on the lower end face of the workbench 10. A connecting hose 46 is connected between the gas storage tank 44 and the second U-shaped hollow plate 32. A vacuum pump 45 is connected inside the connecting hose 46. When welding, the vacuum pump 45 is started. The vacuum pump 45 adsorbs the argon gas sprayed by the multiple jet heads 36 into the interior of the second U-shaped hollow plate 32 through the connecting hose 46, the second U-shaped hollow plate 32, and the multiple horn-shaped gas inlets 43. Then, it is collected and stored in the gas storage tank 44 through the connecting hose 46, which facilitates the subsequent purification and reuse of argon gas. Example 2:

[0030] Based on Example 1, further examples are made, such as... Figure 4 and Figure 7As shown, in order to prevent the argon gas from being collected and adsorbed during welding, the argon gas collection and adsorption force can also be used to adsorb and collect the welding slag generated during welding. If the welding slag is not filtered and collected, it will easily cause the welding slag to clog the connecting hose 46 and other components. Therefore, multiple V-shaped filter plates 39 are set inside the second U-shaped hollow plate 32. A waste chip trough 40 is connected between every two adjacent V-shaped filter plates 39. The argon gas and welding slag entering the second U-shaped hollow plate 32 through multiple horn-shaped gas inlets 43 are guided and filtered by the multiple V-shaped filter plates 39. The welding slag is stored inside the waste chip trough 40, and the filtered argon gas is stored inside the gas storage tank 44 through the connecting hose 46.

[0031] Furthermore, such as Figure 7 As shown, multiple support plates 41 are fixedly installed on one side of the multiple V-shaped filter plates 39 on the inner wall of the second U-shaped hollow plate 32. Each support plate 41 is connected to its adjacent V-shaped filter plate 39 by a second spring 42. The support plates 41 and the second springs 42 provide elastic support for the multiple V-shaped filter plates 39. When the V-shaped filter plates 39 filter the argon gas entering the second U-shaped hollow plate 32, the gas will impact the inclined end face of the V-shaped filter plates 39, causing the V-shaped filter plates 39 to vibrate to a certain extent. At this time, the welding slag adhering to the inclined end face of the V-shaped filter plates 39 will fall off and move into the waste slag trough 40 for storage, thereby preventing the filter holes on the inclined end face of the V-shaped filter plates 39 from becoming blocked. Example 3:

[0032] Based on Examples 1 and 2, further examples are made, such as... Figure 2 and Figure 5As shown, to prevent uneven contact surfaces between pipes during welding, resulting in insufficient tightness, a first sliding support frame 23 is fixedly installed below the elongated hole 22 on the lower end face of the workbench 10. A second sliding support frame 24 is slidably installed on the inner bottom surface of the first sliding support frame 23. The second sliding support frame 24 and the first sliding support frame 23 are horizontally moved and transmitted through a motor screw, which is existing technology. A base plate 25 is slidably installed inside the second sliding support frame 24. A grinder 26 is rotatably installed on the upper end face of the base plate 25. The grinder 26 is a common belt grinder, which is existing technology. A third push cylinder is fixedly installed on the lower end face of the pipe. The output end of the third push cylinder passes through the second sliding support frame 24 and is fixedly connected to the lower end face of the base plate 25. Before the pipe is welded, the pipe is first slightly clamped between the first side plate 13 and the clamping plate 14. At this time, the first side plate 13 and the clamping plate 14 mainly guide the pipe, while the squeezing force on the pipe is small. Then, the clamping plate 12 is rotated to adjust the angle of the pipe so that the inclined contact surface of the pipe is parallel to the end face of the grinding belt. Then, one end of the pipe is pushed so that the contact surface of the pipe is in contact with the grinding surface of the grinding belt, thereby improving the flatness of the contact surface of the pipe.

[0033] Furthermore, such as Figure 1 and Figure 4 As shown, an extension plate 18 is fixedly installed on one side of the first side plate 13 on one side of each clamping plate 14. A rotating plate 19 is rotatably installed at one end of each extension plate 18. A third motor is installed at the rotatable connection between the extension plate 18 and the rotating plate 19 to drive the rotating plate 19 to rotate. The third motor is a servo motor. A first extrusion plate 20 is slidably installed on one side of each rotating plate 19. A fourth push cylinder is fixedly installed on one side of each first extrusion plate 20 on the outer side of the rotating plate 19. The fourth push cylinder is an ordinary electric push cylinder. The output end of the fourth push cylinder drives the first extrusion plate 20 to move horizontally towards one end of the pipe, and then closely abuts against one end of the pipe, finally forming a push on one end of the pipe. When one end of the pipe is being polished, it provides a certain pushing force to the other end of the pipe to assist in the polishing process of the pipe.

[0034] Finally, it should be noted that the metal door and window processing and welding device of this invention needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the specific mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0035] Furthermore, the grinding machine, push cylinder, jet nozzle, spring, vision probe, air tank, welding robotic arm, and motor in the metal door and window processing and welding device of this invention are all commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
