Description

Technical Field

[0001] This utility model relates to a welding device for producing steel strips for fire extinguisher tanks, belonging to the technical field of welding equipment. Background Technology

[0002] Fire extinguisher tanks are made from steel strips through stamping, cutting, rolling, and welding. When each roll of steel strip is nearly used up, the next roll needs to be welded to the existing one to ensure continuity and thus allow for continuous tank production. Currently, tank welding involves manually splicing the ends of the steel strips and then manually welding them. Due to individual differences, the welding quality varies, and it's impossible to guarantee a completely satisfactory weld. Furthermore, manual welding is not only labor-intensive but also inefficient. Patent application CN220515721U discloses a longitudinal laser welding device for steel strips, comprising a main body, a main controller on one side of the main body, a door movably connected to one side of the main body, a mounting frame fixedly connected to the top of the main body, a feeding roller fixedly connected to one side of the main body, a guiding roller fixedly connected to the top of the main body, a receiving roller fixedly connected to one side of the main body, a welding box fixedly connected to the top of the main body, a secondary controller fixedly connected to one side of the welding box, a cooling fan on the top of the welding box, a grinding box fixedly connected to the top of the main body, a cooling hole on one side of the grinding box, a laser host fixedly connected inside the welding box, a first drive motor fixedly connected inside the welding box, and a controller fixedly connected inside the welding box. This utility model, through a longitudinal laser welding device for steel strips, has the advantages of reasonable structural design, rapid heat dissipation, and high splicing accuracy, thereby effectively solving the problems and shortcomings of existing devices.

[0003] The aforementioned welding equipment can weld steel strips, solving the problems of difficulty in ensuring welding quality, high labor intensity, and low efficiency inherent in manual welding. However, during splicing, the welding box obstructs the view, making it difficult to observe the relative positions between the steel strip ends and between the steel strip ends and the laser head. This makes splicing difficult and ensures proper welding positioning. Therefore, it is necessary to design a welding device for producing steel strips for fire extinguisher canisters to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for producing steel strips for fire extinguisher tanks that is easy to observe, thereby ensuring the splicing and welding process and guaranteeing the welding quality.

[0005] The technical solution of this utility model is:

[0025] This welding device for producing steel strips for fire extinguisher tanks consists of a frame 1, a translation mechanism, a welding torch 2, a splicing support plate 3, and pressure plates 4. The frame 1 is equipped with the translation mechanism, and the welding torch 2 is mounted on the translation mechanism. Preferably, the welding torch 2 is a gas-shielded welding torch. The translation mechanism moves the welding torch 2 along the weld seam, gradually welding the seam and achieving automatic welding of the steel strip. This effectively reduces the labor intensity caused by manual welding and solves the problem of inconsistent weld quality due to individual differences. A splicing support plate 3 is mounted on one side of the frame 1 to support the ends of the steel strip, allowing the ends to be spliced ​​and welded on the splicing support plate 3. Pressure plates 4 are spaced apart on the splicing support plate 3, meaning pressure plates 4 are located on both sides of the splicing support plate 3, with pressure plates 4 on one side of the splicing support plate 3 spaced apart from those on the other side. The function of the pressure plate 4 is to press the steel strip end tightly onto the splicing support plate 3, thereby fixing the steel strip end and facilitating direct welding of the steel strip end without the need for spot welding. This saves steps, further reduces labor intensity, and improves efficiency. At the same time, when splicing the steel strip end between the pressure plates 4, the steel strip end can be directly observed, making it easy to splice the steel strip and to easily align the welding gun 2 with the weld seam between the steel strips, ensuring welding accuracy and welding effect.

[0026] Both ends of the pressure plate 4 are connected to the splicing support plate 3 by limiting bolts 5, so as to fix the position of the pressure plate 4 on the splicing support plate 3. Set screws 6 are evenly distributed on the pressure plate 4 between the limiting bolts 5, so as to further fix the steel strip by the set screws 6 in conjunction with the pressure plate 4, ensuring that the steel strip is not easily displaced during the welding process and ensuring the welding effect.

[0027] The translation mechanism consists of a guide rod 13, a rack 14, a slide 15, a servo motor 16, a gear 17, and a U-shaped frame 18 arranged in parallel. The rack 14 is arranged between the guide rods 13. The slide 15 is movably mounted on the guide rod 13. The servo motor 16 is arranged on the top of the slide 15. The output shaft end of the servo motor 16 extends to the bottom of the slide 15. The output shaft end of the servo motor 16 extending to the bottom of the slide 15 is provided with a gear 17, which meshes with the rack 14. The U-shaped frame 18 is arranged on the slide 15. The guide rods 13 and the rack 14 are respectively fixedly connected to the frame 1. A sleeve 19 is provided at the end of the U-shaped frame 18. A rotating positioning component 20 is inserted into the sleeve 19, and a support rod 21 is inserted into the rotating positioning component 20. The end of the support rod 21 extends above the pressure plate 4 and is fixedly connected to the welding gun 2. The rotating positioning component 20 and the sleeve 19, as well as the support rod 21 and the rotating positioning component 20, are fixedly connected by locking bolts 22. The function of the servo motor 16 is to drive the gear 17 to rotate, and then drive the servo motor 16 to translate through the interaction between the gear 17 and the rack 14, which in turn drives the slide 15 to translate, so that the slide 15 can drive the U-shaped frame 18 to translate. During the movement of the U-shaped frame 18, the U-shaped frame 18 drives the welding gun 2 to move sequentially through the sleeve 19, the rotating positioning component 20, and the support rod 21, thereby gradually welding the end of the steel strip. The rotating positioning component 20 can rotate and move up and down in the sleeve 19, thereby driving the welding torch 2 to rotate and move up and down through the support rod 21; the support rod 21 can adjust the horizontal distance between the welding torch 2 and the rotating positioning component 20, and can adjust the position of the welding torch 2 in conjunction with the lifting and rotation of the rotating positioning component 20, so as to ensure that the welding torch 2 can accurately weld the end of the steel strip.

[0028] On the outer side of the translation mechanism and on the outer side of the splicing support plate 3, there are support plates 23 at the same height as the splicing support plate 3.

[0029] When the welding device for the steel strips used to produce fire extinguisher tanks is in operation, the end of the steel strip is passed over the support plate 23 and inserted between the pressure plate 4 and the splicing support plate 3 from the bottom. The end of the steel strip is then spliced ​​in the middle of the splicing support plate 3 between the pressure plates 4. After the end of the steel strip is spliced, the limiting bolt 5 is tightened, and if necessary, the set screw 6 is tightened to fix the end of the steel strip on the splicing support plate 3. After the end of the steel strip is spliced ​​and fixed, the position of the welding torch 2 is finely adjusted by adjusting the position of the rotating positioning component 20 and the support rod 21 to align the welding torch 2 with the weld seam. After the welding torch is in position, the servo motor 16 of the translation mechanism is started. The servo motor 16 drives the welding torch 2 to move sequentially through the gear 17, rack 14, slide 15, U-shaped frame 18, sleeve 19, rotating positioning frame 20, and support rod 21 to weld the end of the steel strip. After welding is completed, the limiting bolt 5 is loosened and the steel strip is removed from the bottom of the pressure plate 4.

[0030] As an improvement, one end of the splicing support plate 3 is hinged to the pressure plate 4, and a fixing cylinder 7 is arranged side by side at the bottom of the other end of the splicing support plate 3. The piston rod of the fixing cylinder 7 extends above the splicing support plate 3, and a pressure head 8 is provided at the end of the piston rod of the fixing cylinder 7 extending above the splicing support plate 3. The pressure head 8 abuts against the end of the pressure plate 4. The function of the fixing cylinder 7 is to pull the pressure head 8 down, thereby pressing the end of the pressure plate 8 through the pressing head 8, which in turn cooperates with the hinge at the other end of the pressure plate 4 to press the fixed pressure plate 4, thereby pressing the steel strip end below the fixed pressure plate 4.

[0031] The bottom of the pressure plate 4 is provided with a buffer layer 9 (such as a rubber layer). On the one hand, the buffer layer 9 reduces the pressure of the pressure plate 4, ensuring that the pressure plate 4 is not easily damaged by the steel strip; on the other hand, the buffer layer 9 increases the friction with the steel strip, ensuring that the steel strip is accurately fixed and not easily moved.

[0032] A slot 10 is provided in the middle of the splicing support plate 3, and a positioning plate 11 is movably inserted into the slot 10. A lifting cylinder 12 is installed at the bottom of the splicing support plate 3 via a bracket, and the piston rod end of the lifting cylinder 12 is fixedly connected to the positioning plate 11. The function of the lifting cylinder 12 is to drive the positioning plate 11 to rise and fall in the slot 10, so that when the top of the positioning plate 11 rises above the splicing support plate 3, the end of the steel strip is positioned by the positioning plate 11, thereby determining the weld position and eliminating the need for frequent adjustments to the position of the welding torch 2.

[0033] When the welding device for the steel strip of the fire extinguisher tank is in operation, the lifting cylinder 12 is activated, which moves the positioning plate 11 upward, so that its top end is above the end of the steel strip. After the positioning plate 11 is in position, the end of the steel strip passes through the support plate 23 from above and is inserted between the pressure plate 4 and the splicing support plate 3 from the bottom, so that the end of the steel strip abuts against the positioning plate 11 between the pressure plates 4. After the end of the steel strip is in position, the fixing cylinder 7 is activated, which presses and fixes the end of the steel strip onto the splicing support plate 3 through the pressure head 8 and the pressure plate 4 in sequence. After the end of the steel strip is spliced ​​and fixed, the lifting cylinder 12 is reset, thereby resetting the positioning plate 11. After the positioning plate 11 is reset, the servo motor 16 of the translation mechanism is started. The servo motor 16 drives the welding gun 2 to move through the gear 17, rack 14, slide 15, U-shaped frame 18, sleeve 19, rotating positioning frame 20, and support rod 21 in sequence to weld the end of the steel strip. After welding is completed, the fixing cylinder 7 is started to release the pressure head 8 and remove the steel strip from the bottom of the pressure plate 4.

[0034] This welding device for producing steel strips for fire extinguisher tanks can pass between pressure plates 4 and splicing support plates 3, splicing between the pressure plates 4. Since there are no obstructions between the pressure plates 4, the splicing process can be easily adjusted to ensure the splicing effect and that the joint position corresponds to the welding torch, thus ensuring accurate welding. A translation mechanism can move the welding torch 2, enabling automatic welding, thereby effectively improving efficiency, reducing labor intensity, and ensuring welding quality. This solves the problems of difficulty in splicing and difficulty in ensuring the welding position existing in welding equipment.
