Description

Technical Field

[0001] The invention belongs to the technical field of welding processing, in particular to a metal door and window processing welding device. Background Art

[0002] Metal door and window processing and welding equipment is a comprehensive equipment that integrates multiple technologies such as welding technology, automatic control and mechanical transmission. It can achieve efficient and high-quality welding of metal doors and windows by precisely controlling welding parameters and welding process. Metal door and window processing and welding equipment is widely used in construction, home furnishing, decoration and other fields. It is an indispensable and important equipment in the manufacturing process of metal doors and windows. With the continuous development of science and technology, the performance and efficiency of metal door and window processing and welding equipment are also constantly improving, providing strong support for the development of the metal door and window manufacturing industry.

[0003] A Chinese patent with announcement number CN114406546A discloses a welding device for metal doors and windows, including a lifting mechanism and a main body. Through the arrangement of an elastic membrane and a pressure rod, the downward movement of the main body allows the pressure rod to overcome the elastic force of the elastic rope, thereby unfolding and generating downward pressure on the welding component. At the same time, the downward moving main body drives the ring seat to contact the welding component, causing the elastic membrane to stretch upward, resulting in negative pressure in the cavity below the elastic membrane in the air cavity. The negative pressure generates suction on the welding component. Compared with the original device, additional fixing force is added on the basis of the original downward pressure, thereby improving the fixing effect of the welding component and reducing the probability of welding deformation.

[0004] In the current existing technology, after welding one side of the metal door and window, it is necessary to turn it over and weld the other side again to enhance the firmness of the welding. However, after welding the first side, the welding slag will fall onto the door and window panels during the welding process, and weld scars will appear at the welds. The welding slag and weld scars will form a layer of covering or protrusions on the surface of the metal door and window, which will affect the aesthetics of the metal door and window, and will also cause the door and window panels to be unevenly placed, affecting the accuracy and strength of the second welding operation.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 10 As shown, a metal door and window processing and welding device described in an embodiment of the present invention includes a base plate platform 1, a welding platform 2 is symmetrically arranged above the base plate platform 1, two door and window frames 3 are placed above the welding platform 2, and a plurality of movable grooves 5 are opened on the top surfaces of the two welding platforms 2, and the inner wall of each movable groove 5 is slidably connected to a limiting column 4, and the outer wall of the limiting column 4 is fitted with the side of the door and window frame 3, and clamping components for fixing the two door and window frames 3 in position are arranged on both sides of the welding platform 2, and flipping components for driving the two door and window frames 3 to rise and flip are arranged on both sides above the welding platform 2, and a scraping component for cleaning welding slag and welding scars is arranged directly above the welding platform 2, and extrusion components for driving the two welding platforms 2 to be pulled apart and separated are arranged on both sides of the base plate platform 1, and an external laser welding component is arranged directly above the door and window frame 3.

[0035] During work, the two door and window frames 3 to be welded are placed directly above the welding table 2. The limiting columns 4 on both sides of the door and window frames 3 are moved and made to fit the outer walls of the two sides of the door and window frames 3. The two sides of the door and window frames 3 are positioned, and then the other two sides of the door and window frames 3 are clamped and fixed by the positioning components. After completion, the welding work is started by the laser welding component. Under the cooperation of positioning and clamping and fixing, the two door and window frames 3 will not be offset in position during the welding process, which improves the stability of the weld during welding. During the welding of the first sides of the two door and window frames 3, welding slag will splash onto the door and window frames At any position on the surface of the frame 3, a raised weld scar will appear at the weld seam. At this time, the two door and window frames 3 are driven to rise and flip through the flip assembly, and when rising, the two door and window frames 3 will first flip 90 degrees. After flipping halfway, the two door and window frames 3 will continue to rise in a vertical state. In the process of continuing to rise, the two door and window frames 3 will pass through the scraping slag assembly, which can clean the welding slag and weld scars adhered to the surfaces of the two door and window frames 3. After cleaning, the two door and window frames 3 are lowered and reset through the flip assembly. During the resetting process, the two door and window frames 3 continue to flip for the second time, and finally the complete The flipping process, after flipping, the other sides of the two door and window frames 3 face upwards, which is convenient for the second welding to increase the firmness between the two door and window frames 3, and by squeezing out the components, after the two door and window frames 3 are in the rising process, the two welding platforms 2 can be pulled apart from each other toward the outside of the bottom plate platform 1 to prevent the scraped welding slag and welding scar debris from falling onto the welding platform 2, and to prevent the welding slag and welding scar debris from being embedded in the interior of the door and window frames 3 and causing damage to the surface of the door and window frames 3 when the two door and window frames 3 are flipped over and placed on top of the welding platform 2. At the same time, it is also convenient to collect the welding slag and welding scar debris. Through the above embodiment, flipping When the rotating component drives the door and window frame 3 to rise for the first flip, the two door and window frames 3 will continue to rise in a vertical state after the first flip, and cooperate with the slag scraping component to clean the welding slag and welding scars. When the door and window frame 3 descends, it will completely flip for the second time to realize the complete flipping process. The work of cleaning welding slag and welding scars is completed during the flipping process, which significantly reduces the time required for cleaning, simplifies the production process, reduces production steps, and improves the overall production efficiency. By squeezing out the component, it can also prevent the cleaned welding slag and welding scar debris from falling directly above the welding table 2, and optimize the production environment while also facilitating the collection of debris.

[0036] like Figures 4 to 5 As shown, the clamping assembly includes two inner sliders 6, the inner walls of the two inner sliders 6 are rotatably connected to a fixed plate 7, a telescopic rod 8 is fixedly installed on the side of the fixed plate 7, one end of the telescopic rod 8 is fixedly connected to a clamp plate 9, and the inner thickness of the two clamp plates 9 is the same as the thickness of the door and window frame 3.

[0037] During operation, after placing the two door and window frames 3 to be welded directly above the welding table 2, the two clamp plates 9 are driven by the two telescopic rods 8 to move closer to each other until the outer walls of the two door and window frames 3 are tightly clamped. After the first side of the door and window frames 3 are welded, the two door and window frames 3 are fixedly connected together, and the flip assembly can be driven to rise by the inner slider 6. When the inner slider 6 rises, the fixed plate 7 and the clamp plate 9 can be flipped, thereby achieving the effect of driving the two door and window frames 3 that have been connected together to flip.

[0038] like Figures 4 to 5 As shown, the flip assembly includes two fixed straight slides 10, the inner walls of the two fixed straight slides 10 are respectively slidably connected to the outer walls of the two inner sliding blocks 6 and adapted to each other, the bottoms of the two fixed straight slides 10 are each provided with a telescopic cylinder 11, the two telescopic cylinders 11 are respectively fixedly installed on the top of the base plate 1, the output end of the telescopic cylinder 11 is fixedly connected to the bottom of the inner sliding block 6, the sides of the two fixed straight slides 10 are each provided with a side slide groove 12, one side of the two inner sliding blocks 6 is each fixedly connected with a gear 13, the shaft rod of the gear 13 is slidably connected to the side slide groove 12 and adapted to each other, the shaft rod of the gear 13 passes through the inner wall of the inner sliding block 6 and is fixedly connected to the fixed plate 7, a rack plate 14 is respectively provided above the two gears 13, and a transposition assembly is provided on one side of the rack plate 14, and the transposition assembly is used to drive the rack plate 14 to switch its position.

[0039] During operation, the telescopic cylinder 11 is started, and its output end will drive the inner slider 6 to slide upward on the inner wall of the fixed straight slide seat 10. The inner slider 6 will drive the shaft of the gear 13 to rise along the side slide groove 12, and will also drive the clamping assembly and the door and window frame 3 on one side to rise. During the rising process, the gear 13 will first rotate 90 degrees to make the two door and window frames 3 flip to a vertical state. At this time, the inner slider 6 continues to rise. During this process, the slag scraping assembly can clean the welding slag and welding scars. After cleaning, the telescopic cylinder 11 drives the inner slider 6 to descend and reset on the inner wall of the fixed straight slide seat 10. During the descent, the two gears 13 continue to rotate 90 degrees again in the direction of the first flipping, driving the door and window frame 3 to flip over and fall back to the top of the welding table 2.

[0040] like Figures 6 to 8 As shown, the teeth of the rack plate 14 mesh with the teeth of the gear 13, and the number of teeth of the rack plate 14 is one quarter of the number of teeth of the gear 13.

[0041] During operation, after the door and window frame 3 rises and leaves the surface of the welding table 2 with enough space for flipping, the teeth of the gear 13 can now mesh with the teeth of the rack plate 14, and since the number of teeth of the rack plate 14 is one-fourth of the number of teeth of the gear 13, the gear 13 will drive the door and window frame 3 to rotate exactly 90 degrees, so that the door and window frame 3 remains in a vertical state, and the door and window frame 3 continues to rise while remaining in a vertical state. After the slag scraping assembly cleans the welding slag and welding scars, the door and window frame 3 begins to descend and reset. During the descent, the rack plate 14 switches its position through the transposition assembly and shifts to the other side of the gear 13. When the gear 13 descends, it can still mesh with the rack plate 14, and the direction of this meshing is the same as the direction of the first meshing, thereby realizing a complete flipping process.

[0042] like Figure 6 to Figure 7 As shown, the scraping assembly includes two scraping plates 15, the distance between the two scraping plates 15 is the same as the thickness of the door and window frame 3, a frosting plate 16 is fixedly installed at the middle position of the two scraping plates 15, the outer walls of the two scraping plates 15 are fixedly connected with clamping members 17, the top of the clamping members 17 is fixedly connected with a fixing frame 18, and two fixed straight sliding seats 10 are fixedly installed at the bottom of both ends of the fixing frame 18 respectively.

[0043] During operation, when the door and window frame 3 completes the first flip and continues to rise in a vertical state, it will pass through the gap between the two scraper plates 15. Since welding slag and welding scars will form protrusions on the surface of the door and window frame 3, by setting the distance between the two scraper plates 15 to be the same as the thickness of the door and window frame 3, the door and window frame 3 can scrape off the welding slag when passing through the gap between the two scraper plates 15, and can grind and clean the welding scars when passing through the gap between the two grinding plates 16. The clamping piece 17 and the fixing frame 18 facilitate the fixing of the scraper plate 15 and the door and window frame 3 can also pass through the scraper plate 15 completely.

[0044] like Figures 9 and 10 As shown, the extrusion assembly includes two symmetrical side connecting plates 37, and each of the two side connecting plates 37 is fixedly installed directly above the welding table 2. A hinge rod 36 is hinged on one side of the side connecting plate 37, and one end of the hinge rod 36 is fixedly connected to a limiting slider 35. The bottoms of the two welding tables 2 are fixedly connected with a supporting moving block 38, and the top surface of the base plate 1 is symmetrically provided with an inner slide groove 2 39, and the supporting moving block 38 is slidably connected and matched with the inner slide groove 2 39, and a collection box 40 is arranged on the top of the base plate 1, and the collection box 40 is located below the middle position of the two welding tables 2.

[0045] During operation, when the inner slide block 6 rises, it will squeeze the two sets of limit slide blocks 35 to move toward the outside of the base plate 1, and the limit slide block 35 will drive the two welding platforms 2 to move away from each other through the hinge rod 36 and the side connecting plate 37, realizing the pulling apart process. During the pulling apart process, the supporting moving block 38 at the bottom of the welding platform 2 will slide in the inner wall of the inner slide groove 2 39. When the door and window frame 3 is in the process of rising, flipping and scraping slag, the two welding platforms 2 are separated from each other, and the welding slag and welding scar debris will fall into the collection box 40 between the two welding platforms 2 for collection. When the door and window frame 3 descends and resets, the two welding platforms 2 are reunited.

[0046] like Figures 9 and 10 As shown, the side surfaces of the fixed straight slide seat 10 are symmetrically provided with side slide grooves 31, and both sides of the inner slide block 16 are fixedly connected with sliding rods 32, the sliding rods 32 and the side slide grooves 31 are slidingly connected and adapted to each other, one end of the sliding rod 32 is fixedly connected with a quadrilateral frame 33, and the inner wall of the quadrilateral frame 33 is provided with an inner slide groove 34, which is divided into an inclined area and a straight area, and the inner slide groove 34 and the limit slide block 35 are slidingly connected and adapted to each other.

[0047] During operation, when the inner slide block 6 rises, the sliding rod 2 32 will rise along the inner wall of the side slide groove 2 31, and the sliding rod 2 32 will drive the quadrilateral frame 33 to rise. During the rising process of the quadrilateral frame 33, the limiting slide block 35 will slide on the inner wall of the inner slide groove 1 34. Before the door and window frame 3 is flipped for the first time, the entire limiting slide block 35 slides along the inclined area of ​​the inner slide groove 1 34. During this sliding, the limiting slide block 35 will continue to be squeezed to slide outward, so that the two welding tables 2 are pulled apart and separated. When scraping slag after the first flipping, the limiting slide block 35 slides in the straight area of ​​the inner slide groove 1 34. At this time, the two welding tables 2 remain stationary. When the inner slide block 6 drives the quadrilateral frame 33 to descend, the two welding tables 2 can be reunited.

[0048] like Figure 8 As shown, the transposition assembly includes two fixed side slides 23, and the two fixed side slides 23 are fixedly installed on the top of the base plate 1. The top of the fixed side slide 23 is fixedly connected with a connecting frame 29, and the bottom of the connecting frame 29 is fixedly connected to one side of the fixed frame 18. An electromagnet 24 is fixedly installed at one end of the fixed side slide 23. The inner wall of the fixed side slide 23 is slidably connected with an inner slider 20, and the inner slider 20 is made of iron. One side of the inner slider 20 is rotatably connected with a rotating rod 19, and one end of the rotating rod 19 is fixedly connected to one side of the rack plate 14. A control button 30 is provided on the inner side of the top of the fixed straight slide 10.

[0049] During operation, when the inner slider 16 rises to the highest point on the inner wall of the fixed straight slide seat 10, it will touch the control button 30, and the control button 30 will control the electromagnet 24 to be energized. After the electromagnet 24 is energized, it will attract the inner slider 20 made of iron to slide on the inner wall of the fixed side slide seat 23 toward the electromagnet 24. The inner slider 20 drives the rack plate 14 to move through the rotating rod 19, and the rack plate 14 can rotate 180 degrees during the movement. When the rack plate 14 reaches the position after moving, its teeth can just align with the teeth of the gear 13, so that the gear 13 can also mesh with it when it descends, so that the door and window frame 3 completes the final flipping work.

[0050] like Figure 8 As shown, the outer wall of the rotating rod 19 is fixedly connected to a sector gear 21, the teeth of the sector gear 21 are meshed with a rack plate 22, the number of teeth of the rack plate 22 is the same as the number of teeth of the sector gear 21, the rack plate 22 is fixedly installed on one side of a fixed side slide seat 23, the top surface of the fixed side slide seat 23 is provided with a top surface slide groove 25, the top end of the inner slider 20 is fixedly connected to a sliding rod 1 26, the sliding rod 1 26 and the top surface slide groove 25 are slidably connected and adapted to each other.

[0051] During operation, when the inner slider 20 drives the rack plate 14 to move through the rotating rod 19, the sector gear 21 will mesh with the teeth of the rack plate 22, and because the number of teeth of the rack plate 22 is the same as that of the sector gear 21, the sector gear 21 will rotate 180 degrees when passing through the rack plate 22, and drive the rack plate 14 to rotate 180 degrees through the rotating rod 19. After the rack plate 14 rotates to the other side of the gear 13, its teeth can just align with the teeth of the gear 13, and through the top surface sliding groove 25 and the sliding rod 1 26, the position of the rack plate 14 after moving is just the position meshing with the other side of the gear 13. The rack plate 14 remains in place after being reset.

[0052] like Figure 8 As shown, a return spring 27 is fixedly connected to one side of the inner slider 20, and a damping rod 28 is arranged inside the return spring 27. One end of the damping rod 28 is fixedly connected to one side of the inner slider 20, and the other side of the damping rod 28 is fixedly connected to the inner side surface of the fixed side slide seat 23.

[0053] During operation, through the reset spring 27 and the damping rod 28, after the inner slider 6 descends and resets to the lowest end, the electromagnet 24 is powered off, and the inner slider 20 and the rack plate 14 are automatically reset under the action of the reset spring 27 and the damping rod 28, so that the gear 13 can continue to mesh and rotate with it when it rises next time.
