Description

Technical Field

[0001] This invention relates to the field of cold-formed hollow steel pipe processing technology, specifically to a tilted extrusion frame for a large-diameter cold-formed hollow steel extrusion forming device. Background Technology

[0002] Cold-formed hollow steel pipes include square, rectangular, and round pipes. They possess core advantages such as lightweight, high strength, flexible cross-sections, and ease of processing, and are widely used in construction, transportation, machinery, energy, and other fields. During the processing of cold-formed hollow steel pipes, an extrusion forming machine is required. When the extrusion forming machine is working, the raw material is extruded into the required shape by extrusion rollers, i.e., cold bending. Afterwards, welding is performed. For example, Chinese utility model patent application number 201821433385.0, filed on 2018-09-03, discloses an I-beam cold bending machine, which includes a worktable, a transmission unit, and a support unit. During operation, it provides excellent bending effect and high processing accuracy, while minimizing flange deformation. However, during the welding process, a large amount of welding slag is generated and remains on the workpiece. If not cleaned promptly, the welding slag residue in the area to be welded will directly hinder the weld pool from forming. The effective combination of the base material, molten pool, and welding material affects subsequent processing. To overcome this deficiency, Chinese utility model patent application No. 202321477391.7, filed on June 12, 2023, discloses a cold bending machine with slag blowing function. During use, as the galvanized sheet slides slowly, the galvanized sheet drives two force-bearing turntables on the limiting mechanism to rotate, thereby alternately blowing air onto the galvanized sheet and blowing off the slag on the surface of the galvanized sheet. This reduces the possibility of damage to the surface of the galvanized sheet when it passes through two pusher rollers and pusher components. However, since welding slag is a metallic material, airflow is difficult to achieve a stable cleaning effect during the slag cleaning process. The device in the aforementioned application has a poor cleaning effect during use, and welding slag remains on the workpiece, causing unnecessary trouble for subsequent processing. Summary of the Invention

[0003] The purpose of this invention is to provide an inclined extrusion frame for a large-diameter cold-formed hollow steel extrusion molding device to solve the problem of poor cleaning effect in the above-mentioned background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

The reciprocating assembly includes a rotating shaft rotatably disposed inside the connecting plate, and the spray cooling plate is fixedly connected to the surface of the rotating shaft. The spray cooling plate is distributed at an angle.

[0007] Preferably, a gear is fixedly connected to the end of the rotating shaft, a limit rod is fixedly connected to the surface of the lower plate, and a rack that meshes with the gear is sleeved on the surface of the limit rod.

[0008] Preferably, a protruding rod is fixedly connected to the side of the rack, and the end of the protruding rod is located inside the groove, and the groove is annular spiral. The spray cooling plate is connected to the water tank through an external hose.

[0009] Preferably, a pulley is sleeved and connected to the surface of the connecting shaft, and the other side of the pulley is sleeved and connected to the surface of the long pin, and a cam is fixedly connected to the surface of the long pin.

[0010] Preferably, the reversing assembly includes a guide plate fixedly connected to the surface of the lower connecting plate, and a force-bearing plate corresponding to the cam is slidably disposed on the surface of the guide plate, and a lower connecting rod is fixedly connected to the lower surface of the force-bearing plate.

[0011] Preferably, the front of the lower connecting rod is an inverted "L" structure, and the cleaning plate is sleeved and connected to the surface of the lower connecting rod. A brush is provided on the lower surface of the cleaning plate. A spring shock absorber is fixedly connected to the lower surface of the force plate, and the other side of the spring shock absorber is fixedly connected to the inner wall of the guide plate. The front of the guide plate is an inverted "U" shape.

[0012] Preferably, the cleaning plate has a guide groove on its side, and the guide groove is curved. A guide rod is fixedly connected to the surface of the lower plate, and the guide rod has an inverted "L" structure when viewed from above, and the end of the guide rod is located inside the guide groove.

[0013] Preferably, a counterweight rod is fixedly connected to the lower surface of the movable plate, and the counterweight rods are symmetrically distributed on both sides of the movable plate, and the counterweight rods penetrate through the interior of the water tank.

[0014] Preferably, the lower surface of the counterweight rod is in contact with the upper surface of the spray cooling plate, and the surface of the movable plate is provided with through holes, which are evenly distributed on the surface of the movable plate.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: Adopting a novel structural design, during processing, the motor starts, causing the connecting shaft and cylinder to rotate. The rack, under the action of the groove, the convex rod, and the limiting rod, then performs reciprocating linear motion in the horizontal direction. At this time, the rack and gear cooperate to drive the rotating shaft and the spray cooling plate to swing, thus increasing the working range of the spray cooling plate and improving the cooling effect. Simultaneously, during this process, the long pin drives the cam to rotate synchronously, causing the force plate, under the action of thrust and elasticity, to move the lower connecting rod and the cleaning plate in the vertical direction. At the same time, the cleaning plate, under the action of the guide rod and guide groove, moves in the horizontal direction, thus widening the working range of the cleaning plate and improving the cleaning effect. Furthermore, a movable plate is installed inside the water tank. When the movable plate is working, it agitates the water, preventing impurities from settling, thus facilitating the stable operation of the entire device. The specific details are as follows:

[0016] (1) The inclined extrusion frame of the large-diameter cold-formed hollow steel extrusion forming device is used to feed the frame body through the feeding component during the working process. The processing is completed inside the frame body. At this time, the scraper plays the role of scraping off the welding waste. At the same time, the motor works. The motor drives the connecting shaft and the cylinder to work. Then, the rack moves in a reciprocating linear motion in the horizontal direction under the action of the groove, the convex rod and the limit rod. At this time, the rack and the gear cooperate to drive the rotating shaft and the spray cooling plate to swing. Then, the working range of the spray cooling plate increases and the cooling effect is better.

[0017] (2) The inclined extrusion frame of the large-diameter cold-formed hollow steel extrusion forming device, when the connecting shaft rotates, the connecting shaft drives the long pin and the cam to rotate synchronously through the belt pulley. When the cam rotates, it will intermittently push the force plate. At this time, under the action of the thrust, the guide plate and the spring damper, the force plate drives the lower connecting rod and the cleaning plate to make reciprocating linear motion in the vertical direction. At this time, the cleaning plate plays the role of scraping and cleaning. The cleaning plate and the scraper work together to quickly clean the welding slag.

[0018] Furthermore, as the cleaning plate descends, it slides on the surface of the lower connecting rod under the action of the guide rod and guide groove. At this time, the cleaning range of the cleaning plate increases, which optimizes the cleaning effect of welding slag and improves work efficiency.

[0019] (3) The inclined extrusion frame of the large-diameter cold-formed hollow steel extrusion forming device moves up and down on the cleaning plate. Under the action of the push rod, torsion spring and auger plate, the cleaning plate rotates back and forth inside the cleaning plate. At this time, the cleaning plate also has the function of efficient cleaning, which optimizes the cleaning effect.

[0020] (4) The inclined extrusion frame of the large-diameter cold-formed hollow steel extrusion forming device will intermittently push the counterweight rod when the spray cooling plate swings. Then, under the action of the thrust and its own weight, the counterweight rod will drive the movable plate to make reciprocating linear motion inside the water tank. At this time, the movable plate and the through hole play the role of stirring the water and preventing impurities from settling, so that the water can be used better, thereby ensuring the overall working efficiency of the device.

[0032] 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.

[0033] Please see Figures 1-10 The present invention provides the following technical solution: a tilting extrusion frame for a large-diameter cold-formed hollow steel extrusion forming device.

[0034] Example 1: Through the reciprocating components, the spray cooling plate 14 can cool the air from multiple angles, resulting in high working efficiency. Figures 1-6 as well as Figure 10 As shown, the machine includes a frame body 1. A feeding assembly is provided on the right side of the frame body 1, and a slanted feeding roller is provided on the feeding assembly. A working plate 29 is bolted to the inner wall of the frame body 1. A lower connecting plate 2 is fixedly connected to the lower surface of the working plate 29, and a connecting plate 3 is fixedly connected to the lower surface of the working plate 29. A spray cooling plate 14 is connected to the connecting plate 3 through a reciprocating assembly. A motor 6 is bolted to the left side surface of the lower connecting plate 2, and a connecting shaft 7 is fixedly connected to the output end of the motor 6. A long pin 17 is rotatably provided inside the lower connecting plate 2. A water tank 5 is provided on the upper surface of the working plate 29, and a movable plate 27 is movably provided inside the water tank 5. A scraper 4 is bolted to the lower surface of the working plate 29.

[0035] A cylinder 8 is fixedly connected to the end of the connecting shaft 7, and a groove 10 is provided on the surface of the cylinder 8. The reciprocating assembly includes a rotating shaft 12 rotatably disposed inside the connecting plate 3, and a spray cooling plate 14 is fixedly connected to the surface of the rotating shaft 12. The spray cooling plate 14 is inclined. A gear 13 is fixedly connected to the end of the rotating shaft 12. A limit rod 9 is fixedly connected to the surface of the lower connecting plate 2, and a rack 11 that meshes with the gear 13 is sleeved on the surface of the limit rod 9. A protruding rod 15 is fixedly connected to the side of the rack 11, and the end of the protruding rod 15 is located inside the groove 10. The groove 10 is annular and spiral. The spray cooling plate 14 is connected to the water tank 5 through an external hose.

[0036] During operation, the frame body 1 is fed by the feeding assembly, and the processing is completed inside the frame body 1. When the workpiece is discharged from the weld, the scraper 4 removes the welding waste. At the same time, the motor 6 on the surface of the lower connecting plate 2 works, and then the motor 6 drives the connecting shaft 7 and the cylinder 8 to work. The end of the protruding rod 15 is located inside the groove 10. At this time, the rack 11 performs reciprocating linear motion in the horizontal direction under the action of the groove 10, the protruding rod 15, and the limiting rod 9. At this time, the rack 11 and the gear 13 cooperate to drive the rotating shaft 12 to rotate reciprocally inside the connecting plate 3. When the rotating shaft 12 works, it drives the spray cooling plate 14 to swing synchronously, thereby increasing the working range of the spray cooling plate 14 and improving the cooling effect (e.g., Figure 10 As shown, the external hose serves to supply materials.

[0037] Example 2: Unlike Example 1, the cleaning plate 23 can operate over a wider range through the reversing component, resulting in better cleaning performance. Figure 3 , Figure 4 , Figures 7-9 As shown, a pulley 16 is sleeved and connected to the surface of the connecting shaft 7, and the other side of the pulley 16 is sleeved and connected to the surface of the long pin 17. A cam 18 is fixedly connected to the surface of the long pin 17. A cleaning plate 23 is connected to the surface of the lower plate 2 through a reversing assembly. The reversing assembly includes a guide plate 19 fixedly connected to the surface of the lower plate 2. A force plate 20 corresponding to the cam 18 is slidably arranged on the surface of the guide plate 19, and a lower connecting rod 22 is fixedly connected to the lower surface of the force plate 20.

[0038] The lower connecting rod 22 has an inverted "L" shape when viewed from the front, and a cleaning plate 23 is fitted onto the surface of the lower connecting rod 22. A brush is provided on the lower surface of the cleaning plate 23. A spring shock absorber 21 is fixedly connected to the lower surface of the force plate 20. The other side of the spring shock absorber 21 is fixedly connected to the inner wall of the guide plate 19. The guide plate 19 has an inverted "U" shape when viewed from the front, and a guide groove 25 is provided on the side of the cleaning plate 23. The guide groove 25 is curved. A guide rod 24 is fixedly connected to the surface of the lower connecting plate 2. The guide rod 24 has an inverted "L" shape when viewed from above, and the end of the guide rod 24 is located inside the guide groove 25.

[0039] When the connecting shaft 7 rotates, it drives the long pin 17 and cam 18 to rotate synchronously via the pulley 16. As the cam 18 rotates, it intermittently pushes the force plate 20. When the force plate 20 is pushed, it slides down on the surface of the guide plate 19, at which point the spring damper 21 stores energy. When the force plate 20 is not pushed, it resets under the action of the spring damper 21. This process repeats, causing the force plate 20, the lower connecting rod 22, and the cleaning plate 23 to reciprocate linearly in the vertical direction. During this process, the cleaning plate 23 performs a scraping and cleaning function (e.g., ...). Figure 3 and Figure 4 As shown in the figure, the cleaning plate 23 works in conjunction with the scraper 4 to quickly clean the welding slag.

[0040] When the cleaning plate 23 descends, the guide rod 24 is fixed, and the end of the guide rod 24 is located inside the curved guide groove 25. Therefore, the cleaning plate 23 will slide on the surface of the lower connecting rod 22 under the action of the guide rod 24 and the guide groove 25. At this time, the cleaning range of the cleaning plate 23 increases, which optimizes the cleaning effect of welding slag and improves work efficiency.

[0041] Example 3: The rotating assembly allows the inner shaft 31 and the cleaning plate 32 to operate, such as... Figures 7-9 As shown, the cleaning plate 23 is connected to an inner shaft 31 via a rotary assembly, and a cleaning plate 32 is fixedly connected to the lower surface of the inner shaft 31. The rotary assembly includes a torsion spring 34 fixedly connected to the inner wall of the cleaning plate 23, and the other side of the torsion spring 34 is fixedly connected to the surface of the inner shaft 31. An auger plate 33 is fixedly connected to the surface of the inner shaft 31.

[0042] When the cleaning plate 23 descends, it drives the inner shaft 31 and the sweeping plate 32 to descend synchronously. At this time, the auger plate 33 is pushed by the push rod 30, which causes the auger plate 33, the inner shaft 31 and the sweeping plate 32 to rotate. At the same time, the torsion spring 34 is stretched. When the cleaning plate 23 rises, the auger plate 33, the inner shaft 31 and the sweeping plate 32 rotate under the action of the torsion spring 34. That is, during the up and down movement of the cleaning plate 23, the sweeping plate 32 also has a high-efficiency cleaning function, which optimizes the cleaning effect.

[0043] Example 4: The movable plate 27 allows the water inside the water tank 5 to slosh, thus preventing impurities from settling. Figure 3 and Figure 10 As shown, a counterweight rod 26 is fixedly connected to the lower surface of the movable plate 27, and the counterweight rod 26 is symmetrically distributed on both sides of the movable plate 27. The counterweight rod 26 passes through the interior of the water tank 5. The lower surface of the counterweight rod 26 is in contact with the upper surface of the spray cooling plate 14. Through holes 28 are opened on the surface of the movable plate 27, and the through holes 28 are evenly distributed on the surface of the movable plate 27.

[0044] When the spray cooling plate 14 swings, it intermittently pushes the counterweight rod 26. When the counterweight rod 26 is pushed, it drives the movable plate 27 to rise inside the water tank 5. When the counterweight rod 26 is not pushed, the counterweight rod 26 and the movable plate 27 descend under their own weight. The above process is repeated. Under the action of the thrust and its own weight, the counterweight rod 26 drives the movable plate 27 to make reciprocating linear motion inside the water tank 5. At this time, the movable plate 27 and the through hole 28 play a role in stirring the water and preventing impurities from settling, so that the water inside the water tank 5 can be used better, thereby ensuring the overall working efficiency of the device.

[0045] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
