Abstract
Description
Technical Field
[0001] This utility model belongs to the field of iron drum production technology, specifically relating to a seam welding machine for iron drum production. Background Technology
[0002] A seam welding machine is a resistance welding machine that assembles workpieces into lap or butt joints and places them between two roller electrodes. The roller electrodes apply pressure to the workpieces and rotate, and continuous or intermittent pulse current is supplied to form a continuous weld seam. Seam welding machines are required in the production of iron drums.
[0003] In existing technologies, when welding iron drums, the welding thread slips. The roller electrode is used to fix and limit the area of the iron drum to be welded. However, the effect of limiting the iron drum at a position far from the roller electrode is poor. The area of the iron drum to be welded is prone to displacement, which affects the welding quality. Therefore, a technical measure is proposed to solve the problem that the existing technology has poor effect on limiting the position of the iron drum far from the roller electrode, and the iron drum is prone to displacement at the area to be welded, which affects the welding quality. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a seam welding machine for iron drum production, which aims to solve the problem that the existing technology has poor effect in limiting the position of the iron drum away from the roller electrode, and the iron drum is prone to displacement at the welding point, thus affecting the welding quality.
[0006] (2) Technical solution
[0007] To address the aforementioned technical problems, this utility model provides a seam welding machine for producing iron drums, comprising a main body and a limiting component. A round rod is installed at the middle of the side of the main body, and a lower roller electrode is installed at the end of the round rod. A top plate is installed on the upper side of the main body, and a first electric telescopic rod is installed through the top plate. The lower end of the first electric telescopic rod is connected to a mounting plate, and an upper roller electrode is installed on the mounting plate. Thanks to the setting of the limiting component, it is convenient to limit the part of the iron drum to be welded, preventing the iron sheet from shifting (when subjected to downward pressure, the separation force borne by the middle part of the iron drum is relatively reduced, thus making it less prone to displacement), ensuring welding quality. Furthermore, under the action of the spring, the pressure roller is driven to always press against the iron drum, ensuring the limiting effect. At the same time, the friction between the pressure roller and the iron drum is small, making it convenient to push the iron drum to move.
[0008] Furthermore, a collection box is installed at the lower end of the side of the main body, the main body is provided with a door, and a second electric telescopic rod is installed through the side of the main body.
[0009] Furthermore, the second electric telescopic rod is connected to a movable plate, which is slidably adapted to the round rod. Two sets of symmetrically distributed limiting rods are installed on the side of the movable plate, and the limiting rods are slidably adapted to the main body.
[0010] Furthermore, the movable plate has multiple sets of sliding grooves, and multiple sets of screws are threadedly connected to the middle position of the side of the movable plate.
[0011] Furthermore, the screw is connected to a knob, and a slider is rotatably connected to the end of the screw away from the knob. The slider is slidably adapted to the groove, and a limit plate is installed on the surface of the slider. The limit plate is arc-shaped.
[0012] Furthermore, the limiting component includes a connecting plate, the side of which is mounted on the side of the mounting plate, a side plate is mounted on the side of the connecting plate, and multiple sets of evenly distributed vertical tubes are mounted on the lower surface of the side plate.
[0013] Furthermore, a spring is installed inside the upper part of the vertical tube, and a pressing plate is connected to the lower end of the spring. The pressing plate is slidably fitted with the vertical tube. A vertical rod is installed in the middle of the lower surface of the pressing plate. The vertical rod is slidably fitted with the vertical tube. A frame is connected to the lower end of the vertical rod. Multiple sets of evenly distributed rotating rods are located inside the frame. A pressure roller is connected to the middle of each rotating rod.
[0014] Furthermore, the limiting component also includes a lower top block, which is mounted on the upper surface of the round rod. The lower top block is adapted to the height of the lower roller electrode. The upper end of the lower top block is arc-shaped and the curvature is adapted to the lower roller electrode. The pressure roller is arc-shaped and the curvature is adapted to the upper roller electrode.
[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model, through the addition of a limiting plate, slider, screw, and knob, facilitates the initial positioning of iron barrels of different sizes, and the rotation of the knob drives the limiting plate to move.
[0018] The limiting components facilitate the limiting of the welding area on the iron drum, preventing displacement of the iron sheet (when subjected to downward pressure, the separation force on the middle part of the iron drum is relatively reduced, making displacement less likely), thus ensuring welding quality. Furthermore, the spring ensures the pressure roller remains pressed against the iron drum, guaranteeing the limiting effect. Simultaneously, the low friction between the pressure roller and the iron drum facilitates movement. The interior of the welding area contacts the lower top block. As the upper roller electrode moves downward, it drives the connecting plate, side plate, vertical pipe, vertical rod, spring, extrusion plate, frame, pressure roller, and rotating rod downward. The pressure roller moves downward and presses against the upper surface of the welding area on the iron drum. When the pressure roller presses against the upper surface of the welding area, the vertical rod drives the extrusion plate upward to compress the spring. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This specific embodiment is a seam welding machine for iron drum production, and its structural schematic diagram is shown below. Figure 1 , Figure 2 , Figure 3 As shown, the device includes a main body 1 and a limiting assembly 2. A round rod 10 is installed at the middle of the side of the main body 1, and a lower roller electrode 11 is installed at the end of the round rod 10. A top plate 3 is installed on the upper side of the main body 1, and a first electric telescopic rod 4 is installed through the top plate 3. The lower end of the first electric telescopic rod 4 is connected to a mounting plate 8, and an upper roller electrode 9 is installed on the mounting plate 8. A collection box 6 is installed at the lower side of the main body 1, and the main body 1 has a door 7. A second electric telescopic rod 14 is installed through the side of the main body 1, and a movable plate 5 is connected to the second electric telescopic rod 14. The movable plate 5 is slidably adapted to the round rod 10. Two sets of symmetrically distributed limiting rods 13 are installed on the side of the movable plate 5. The limiting rods 13 are slidably adapted to the main body 1. Multiple sets of sliding grooves 12 are opened inside the movable plate 5. Multiple sets of screws 16 are threadedly connected to the middle of the side of the movable plate 5. A knob 15 is connected to each screw 16. A slider 17 is rotatably connected to the end of the screw 16 away from the knob 15. The slider 17 is slidably adapted to the sliding grooves 12. A limiting plate 18 is installed on the surface of the slider 17. The limiting plate 18 is arc-shaped. In actual production of the iron drum, multiple sets of limiting rods 13 are first adjusted according to the specifications of the iron drum. The distance between the limiting plates 18 ensures that the inner wall of the rolled iron sheet of the iron drum is in contact with multiple sets of limiting plates 18 (when welding the iron drum, the iron sheet needs to be folded into a cylindrical shape before welding, and welding is done in batches), and the area to be welded is on the lower roller electrode 11 (when adjusting the limiting plates 18, the area to be welded can be placed on the lower roller electrode 11 first, and then the limiting plates 18 can be adjusted so that the limiting plates 18 abut against the inside of the iron drum). The specific adjustment method is to rotate the knob 15 to drive the screw 16 to rotate, and the rotation of the screw 16 drives the slider 17. Moving along the slide 12, the slider 17 moves, driving the limiting plate 18 to move. Then, the barrel made of rolled iron sheet is aligned with the lower roller electrode 11 and the limiting plate 18 and inserted. Then, the first electric telescopic rod 4 is activated, driving the upper roller electrode 9 to press against the upper surface of the iron barrel. At this time, the limiting component 2 limits the iron barrel. Then, the upper roller electrode 9 and the lower roller electrode 11 are activated to start welding. During welding, the second electric telescopic rod 14 is activated to push the moving plate 5 to move. The moving plate 5 moves and drives the unwelded part of the iron barrel to pass through the upper roller electrode 9 and the lower roller electrode 11 for welding.
[0028] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the limiting component 2 includes a connecting plate 201, which is mounted on the side of the mounting plate 8. A side plate 202 is mounted on the side of the connecting plate 201. Multiple sets of evenly distributed vertical tubes 203 are mounted on the lower surface of the side plate 202. A spring 208 is mounted inside the upper part of the vertical tube 203. A pressing plate 209 is connected to the lower end of the spring 208. The pressing plate 209 and the vertical tube 203 are slidably fitted together. A vertical rod 210 is mounted in the middle of the lower surface of the pressing plate 209. The vertical rod 210 and the vertical tube 203 are slidably fitted together. A frame 204 is connected to the lower end of the vertical rod 210. Multiple sets of evenly distributed rotating rods 206 are located inside the frame 204. A pressure roller 205 is connected in the middle of the rotating rods 206. The limiting component 2 also includes a lower top block 207. 7 is installed on the upper surface of the round rod 10. The lower top block 207 is adapted to the height of the lower roller electrode 11. The upper end of the lower top block 207 is arc-shaped and the arc is adapted to the lower roller electrode 11. The pressure roller 205 is arc-shaped and the arc is adapted to the upper roller electrode 9. The inside of the iron bucket to be welded is in contact with the lower top block 207. When the upper roller electrode 9 moves downward, it drives the connecting plate 201, side plate 202, vertical pipe 203, vertical rod 210, spring 208, extrusion plate 209, frame 204, pressure roller 205, and rotating rod 206 to move downward. The pressure roller 205 moves downward and abuts against the upper surface of the iron bucket to be welded. When the pressure roller 205 abuts against the upper surface of the iron bucket to be welded, the vertical rod 210 drives the extrusion plate 209 to compress the spring 208 upward.
[0029] Working principle: In actual production of iron drums, firstly, according to the specifications of the iron drum, the distance between multiple sets of limiting plates 18 is adjusted so that the inner wall of the rolled iron sheet of the iron drum is in contact with the multiple sets of limiting plates 18 (when welding the iron drum, the iron sheet needs to be folded into a cylindrical shape before welding, and welding is done in batches). The area to be welded is on the lower roller electrode 11 (when adjusting the limiting plate 18, the area to be welded can be placed on the lower roller electrode 11 first, and then the limiting plate 18 can be adjusted so that the limiting plate 18 abuts against the inside of the iron drum). The specific adjustment method is to rotate the knob 15 to drive the screw 16 to rotate, and the rotation of the screw 16 drives the slider 17 to move along the slide groove 12. The slider 17 moves, causing the limiting plate 18 to move. Then, the barrel made of rolled iron sheet is aligned with the lower roller electrode 11 and the limiting plate 18 and inserted. Then, the first electric telescopic rod 4 is activated, causing the upper roller electrode 9 to press against the upper surface of the iron barrel. At this time, the limiting component 2 limits the iron barrel. Then, the upper roller electrode 9 and the lower roller electrode 11 are activated to start welding. During welding, the second electric telescopic rod 14 is activated to push the moving plate 5 to move. The moving plate 5 moves and causes the unwelded part of the iron barrel to pass through the upper roller electrode 9 and the lower roller electrode 11 for welding. Through the growth of the limiting plate 18, slider 17, screw 16 and knob 15, it is convenient to initially limit the iron barrels of different sizes.
[0030] The specific working principle of the limiting component 2 is as follows: the inside of the iron bucket to be welded contacts the lower top block 207. When the upper roller electrode 9 moves downward, it drives the connecting plate 201, side plate 202, vertical pipe 203, vertical rod 210, spring 208, extrusion plate 209, frame 204, pressure roller 205, and rotating rod 206 to move downward. The pressure roller 205 moves downward and abuts against the upper surface of the iron bucket to be welded. When the pressure roller 205 abuts against the upper surface of the iron bucket to be welded, the vertical rod 210 drives the extrusion plate 209 to compress the spring 208 upward. Through the setting of the limiting component 2, it is convenient to limit the iron bucket to be welded and prevent the iron sheet from shifting (when subjected to downward pressure, the separation force borne by the middle part of the iron bucket is relatively reduced, so it is not easy to shift), thus ensuring the welding quality. Under the action of the spring 208, the pressure roller 205 is always abutted against the iron bucket, ensuring the limiting effect. At the same time, the friction between the pressure roller 205 and the iron bucket is small, making it easy to push the iron bucket to move.

Although the present utility model 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.
