Description

Technical Field

[0001] This invention relates to the field of aluminum formwork processing technology, and in particular to a welding device for aluminum formwork. Background Technology

[0002] Aluminum formwork is a commonly used component in building pouring construction. There are many types of aluminum formwork depending on the building structure, but it is usually a plate structure, specifically including a base plate and stiffening plates. The base plate is mostly an aluminum plate structure with a channel-shaped cross-section, while the stiffening plates are mostly square tube structures. There are multiple square tubes arranged in parallel inside the aluminum plate. In order to reduce the amount of welding deformation, the stiffening plates and aluminum plates are usually fastened together by multiple forging welds on both sides.

[0003] Currently, most common aluminum formwork consists of multiple parallel square tubes welded inside an aluminum plate. Due to the large number of square tubes, they usually need to be clamped one by one before forging and welding. The clamping operation usually involves manually placing the square tubes precisely and then manually operating the clamps to clamp each square tube. This positioning operation before welding greatly reduces the efficiency of the entire aluminum formwork production. At the same time, after the square tubes are fixed, they need to be manually welded in multiple sections, which greatly increases the labor intensity of the welders.

[0004] Therefore, this invention proposes a welding equipment for building aluminum formwork. Summary of the Invention

[0005] The purpose of this invention is to provide a welding equipment for building aluminum formwork in order to solve the problems of low efficiency in pre-welding positioning of existing aluminum formwork and high labor intensity in segmented welding.

The top of the pressure plate is rotatably connected to two drive shafts near both sides via a support plate. The two ends of the drive shaft are fixedly connected to a forward worm and a reverse worm gear that mesh with the forward worm gear and the reverse worm gear, respectively.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1-8A building aluminum formwork welding equipment includes a lifting frame 1, with a pressing and straightening mechanism 2 installed on the top of the lifting frame 1. The lifting frame 1 is used to control the lifting and lowering of the pressing and straightening mechanism 2. The function of the pressing and straightening mechanism 2 is to straighten and press the reinforcing tubes placed inside the aluminum base plate, so that the aluminum tubes are in a precise positioning state inside the aluminum plate, without the need for manual straightening of the positioning reinforcing tubes and the use of corresponding clamps to press the reinforcing tubes.

[0039] The lifting frame 1 is equipped with a left-right position switching mechanism 3 located above the clamping and straightening mechanism 2. Here, "left" and "right" refer to the welding positions on the left and right sides of the reinforcing tube. A telescopic welding part 4 is rotatably and slidably connected to the left-right position switching mechanism 3. The telescopic welding part 4 is the component used for welding at the joint between the reinforcing tube and the aluminum plate; "telescopic" here refers to the adjustable position of the welding head. The left-right position switching mechanism 3 controls the telescopic welding part 4 to switch between the left and right sides of the clamping and straightening mechanism 2, thereby achieving the switching of welding positions. The top of the lifting frame 1 is equipped with a control assembly 5 for controlling the lateral sliding of the telescopic welding part 4. When the telescopic welding part 4 moves laterally, it can perform forging welding. This setup eliminates the need for manual welding with a handheld welding torch 42, greatly reducing labor intensity.

[0040] Specifically, the clamping and straightening mechanism 2 includes a straightener 21 and a drive assembly 22. The straightener 21 includes a pressure plate 211, pressure arms 212, and stop shafts 213. Two pressure arms 212 are rotatably connected to the top of the pressure plate 211 near both sides. The bottom of the pressure plate 211 serves to clamp the top of the rib tube. The bottom of the pressure arm 212 is fixedly connected to the stop shaft 213 located at the free end. The stop shaft 213 is vertical. The drive assembly 22 is located above the straightener 21 and is used to control the adjacent pressure arms 212 to be symmetrical with respect to the middle of the pressure plate 211. When the four pressure arms 212 rotate symmetrically with adjacent pressure arms 212, the four stop shafts 213 will press against both sides of the rib tube. At this time, the inclined rib tube will be straightened by the stop shafts 213, so that the rib tube and the upright plates on both sides of the aluminum plate are perpendicular and abut or nearly abut. At this time, the two sides of the rib tube correspond to the two stop shafts 213 respectively.

[0041] Furthermore, the drive assembly 22 includes a forward worm gear 222, a reverse worm gear 223, a drive shaft 224, and a trigger assembly 221 for controlling the rotation of the drive shaft 224. One end of the pressure arm 212 is fixedly connected to a positioning shaft 2121 that is rotatably connected to the top of the pressure plate 211. The top of adjacent positioning shafts 2121 is respectively fixedly fitted with a forward worm gear 222 and a reverse worm gear 223. The top of the pressure plate 211 is rotatably connected to two drive shafts 224 near both sides through a support plate. The two ends of the drive shaft 224 are fixedly connected to a forward worm 2241 and a reverse worm 2242 that mesh with the forward worm gear 222 and the reverse worm gear 223, respectively. At this time, when the two drive shafts 224 rotate in opposite directions, the transmission structure of the worm gears and worms is used to control the synchronous movement of the four pressure arms 212, and the adjacent pressure arms 212 are in a symmetrical state during movement.

[0042] In this embodiment, the trigger assembly 221 includes a lifting rod 2211 and a transmission gear 2212. A rectangular frame 11 is provided on the lifting frame 1. The lifting rod 2211 is disposed through the middle of the lower crossbeam 111 at the bottom of the rectangular frame 11. The lifting rod 2211 and the lower crossbeam 111 slide together vertically. When in use, a control cylinder is installed on the top of the upper crossbeam 111. The control cylinder controls the lifting rod 2211 to move up and down. The pressure plate 211 is located below the lifting rod 2211, and its top is fixedly connected to a guide shaft 2111 that slides vertically with the lifting rod 2211. In specific implementation, a slide rail that slides with the guide shaft 2111 can be opened at the bottom of the lifting rod 2211. Transmission gears 2212 are fixedly sleeved on both transmission shafts 224. The sides of the lifting rod 2211 are provided with tooth grooves 22112 that mesh with the adjacent transmission gears 2212. That is to say, when the lifting rod 2211 and the pressure plate 211 move relative to each other, the two transmission shafts 224 will rotate in opposite directions due to the meshing of the transmission gears 2212 and the tooth grooves 22112. The bottom of the lower crossbeam 111 is fixedly provided with a pressure frame 1111 near both ends. The function of the pressure frame 1111 is to clamp the upright plates on both sides of the aluminum plate. When the rectangular frame 11 moves downward, it will drive the rectangular frame 11 to press the top of the upright plate, which plays a role in pressing and positioning the welded aluminum plate.

[0043] The lifting frame 1 includes a base 12 and a lifting cylinder 13. A cantilever 121 is fixedly connected to the top of the base 12. The bottom of the cantilever 121 is fixedly connected to the top of the rectangular frame 11 through the lifting cylinder 13. The lifting cylinder 13 is used to control the up and down movement of the rectangular frame 11.

[0044] In this embodiment, the left and right workstation switching mechanism 3 includes a portal frame 31, a belt drive assembly 32, and a switching drive assembly 33. A receiving shaft 1112 near both ends is fixedly mounted on the lower crossbeam 111. A connecting sleeve 311, which is rotatably connected to the open end of the portal frame 31 and the receiving shaft 1112 near both ends of the lower crossbeam 111, is fixedly connected. The horizontal shaft 312 at the top of the portal frame 31 is rotatably mounted. One end of the horizontal shaft 312 is axially slidably connected to the telescopic welding part 4. When the horizontal shaft 312 rotates, it can drive the telescopic welding part 4 to swing. The horizontal shaft 312 is connected to the receiving shaft 1112 via the belt drive assembly 32. The rotation of the horizontal shaft 312... Controlled by the belt drive assembly 32, in a preferred embodiment, the belt drive assembly 32 includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt connecting the first and second synchronous pulleys. The first synchronous pulley is fixedly mounted on the receiving shaft 1112, and the second synchronous pulley is fixedly mounted on the horizontal shaft 312. This arrangement allows the telescopic welding part 4 to swing relative to the portal frame 31 when the portal frame 31 swings, facilitating control of the welding end of the telescopic welding part 4 near the sides of the reinforcing tube and the joint with the aluminum plate. It should be noted that, to achieve the fillet weld function, the diameter of the first synchronous pulley can be set to be smaller than the diameter of the second synchronous pulley. The belt drive assembly 32 is installed such that when the portal frame 31 is located within the rectangular frame 11 and is in a vertical position, the telescopic welding part 4 is also located within the portal frame 31 and is in a vertical position. The switching drive assembly 33 is mounted on the lower crossbeam 111 and is used to control the rotation of the portal frame 31.

[0045] The switching drive group 33 adopts a common structure of switching motor, output gear and passive gear ring. The passive gear ring is fixedly sleeved on the outside of one of the connecting sleeves 311. The switching motor is fixedly mounted on one of the vertical beams 112 and its output shaft is fixedly connected to the output gear. The output gear meshes with the passive gear ring.

[0046] Furthermore, the telescopic welding unit 4 includes an electric telescopic rod 41 and a welding torch 42 fixedly mounted on the actuating end of the electric telescopic rod 41. When the electric telescopic rod 41 is actuated, it can adjust the position of the welding head on the welding torch 42, making it easier to control the welding head to approach the welding area. The non-acting end of the electric telescopic rod 41 is fixedly connected to a slider 411 sleeved on the horizontal axis 312. When the slider 411 slides along the horizontal axis 312, it can drive the welding torch 42 to move laterally. When the welding head of the welding torch 42 is in the forging welding position, the forging welding function will be realized.

[0047] In this embodiment, the control assembly 5 includes a transmission screw 51, a transmission motor 52, and an arched guide rail 53. A guide beam 1121 near the top is fixedly connected between two vertical beams 112 on the rectangular frame 11. The plane of the arched guide rail 53 is perpendicular to the horizontal axis 312, and a slide block 531 that slides and engages with the guide beam 1121 is fixedly connected to the middle of its top. An arc groove 532 is provided at the bottom of the arched guide rail 53, and a limiting block that slides and engages with the arc groove 532 is fixedly connected to the top of the slider 411. Specifically, the limiting block 4111 is located in the arc groove 532. The transmission screw 51 is rotatably connected above the transmission screw 51 and is screwed through and engaged with the slide block 531. When the transmission screw 51 rotates, it drives the arched guide rail 53 to move laterally. When the arched guide rail 53 moves laterally, it can drive the slider 411 in any position to slide, thereby realizing the horizontal forging welding function of the welding gun 42. The transmission motor 52 is fixedly installed on one of the vertical beams 112 and its output shaft is fixedly connected to one end of the screw 51.

[0048] Working principle: Before use, this equipment is used in conjunction with an external support device with a welding table translation function. Specifically, the base 12 is installed on the worktable of the support device by bolts, and the clamping and straightening mechanism 2 is located above the welding table. That is, the vertical plate to be welded is placed on the welding table, and then multiple ribs are placed inside the aluminum plate. After one rib is welded, the welding table is controlled to translate to weld the other rib. In use, when the rib tube is below the clamping and straightening mechanism 2, the rectangular frame 11 is lowered, the pressure frame 1111 clamps the two upright plates of the aluminum plate and stops, then the lifting rod 2211 lowers. When the pressure plate 211 presses against the top of the rib tube, the pressure plate 211 and the lifting rod 2211 will move closer to each other. At this time, the two drive shafts 224 will rotate in opposite directions, and the two horizontal shafts 312 on both sides of the rib plate will approach the rib tube. When the rib tube is squeezed by the four horizontal shafts 312 at the same time, the rib tube is straightened. Then, the portal frame 31 is controlled to swing outward to an outward tilted state. At this time, the welding head on the welding gun 42 on the telescopic welding part 4 will face the rib tube. When the welding head faces the position where the rib tube and the aluminum plate are in contact, the portal frame 31 is controlled to stop swinging, then the electric telescopic rod 41 is controlled to start, so that the welding head is close to the position to be welded. Finally, the screw 51 is controlled to rotate, and the welding gun 42 is started at the same time to realize forging welding. After one side of the rib tube is welded, the portal frame 31 is controlled to swing in the opposite direction to switch the welding position and continue forging welding.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
