Technical Field

[0001] This utility model relates to the field of welding wire processing technology, specifically to a coarse drawing device for carbon dioxide gas shielded welding wire. Background Technology

[0002] Before processing, carbon dioxide shielded welding wire needs to be rough-drawn by a rough drawing device to ensure the quality of the welding wire during further wire drawing.

[0003] A search revealed that prior art publication number CN215355383U discloses a roughing device for the pre-processing of carbon dioxide gas shielded welding wire. This device includes a support, a worktable, a feeding tray, a fixed plate, bearings, a reciprocating screw, a slider, a guide plate, a first gear, a drive motor, a second gear, two support plates, a rotating shaft, a winding wheel, a base plate, and a heating roughing mechanism. The top of the support is connected to the bottom of the worktable, which has a circular groove at its top and an annular groove on its inner wall. An annular slider is mounted on the outer wall of the feeding tray and slides within the annular groove. The bottom of the fixed plate is connected to the top of the worktable, and an opening is provided at its front end. A bearing is mounted at the top of the opening. The reciprocating screw is rotatably connected to the bearing, and its bottom extends below the worktable and connects to the top of the first gear. The slider slides within the opening. This invention allows the welding wire to be adjusted up and down along the guide opening, resulting in uniform and tight winding of the welding wire onto the winding wheel, thus improving winding efficiency and tightness.

[0004] However, the thickness of the welding wire in the carbon dioxide gas shielded welding of this utility model needs to be adjusted and changed according to the welding requirements and conditions. Using only the same type of welding wire for drawing cannot guarantee the usage requirements. Therefore, a carbon dioxide gas shielded welding wire coarse drawing device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a coarse drawing device for carbon dioxide gas shielded welding wire, which has the advantages of adjusting according to different welding wire thicknesses. It solves the problem that the thickness of the welding wire in carbon dioxide gas shielded welding needs to be adjusted according to welding requirements and conditions, and that it is impossible to guarantee the use requirements if only one type of welding wire is used for drawing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon dioxide gas shielded welding wire rough drawing device, including a processing table, a fixing frame fixedly connected to the right end of the upper side of the processing table, a welding wire adjustment device provided inside the fixing frame, and a rotating device provided on the right side of the processing table;

[0007] The welding wire adjustment device includes an inner fixing frame disposed on the fixing frame, an upper threaded rod sleeved on the left side of the fixing frame, two arc-shaped limiting plates threaded to the outside of the threaded rod, and a left sliding rod slidably sleeved on the lower side of the arc-shaped limiting plates.

[0008] The rotating device includes a right-end drive motor fixedly installed on the lower side of the processing table, a first bevel gear fixedly connected to the output end of the drive motor, a second bevel gear meshing with the upper side of the first bevel gear, an internal turntable sleeved on the second bevel gear, two motors fixedly installed on the lower side of the turntable, and a take-up roller fixedly connected to the output end of the motor.

[0009] Furthermore, a heating structure is provided on the upper side of the processing table, the heating structure including a left-end heating box fixedly connected to the upper side of the processing table and multiple heating wires fixedly installed inside the heating box.

[0010] Furthermore, a guide assembly is provided on the upper side of the processing table. The guide assembly includes a fixed frame fixedly connected to the upper side of the processing table and two transmission rollers sleeved on the inner wall of the fixed frame.

[0011] Furthermore, an electric push rod is fixedly installed on the upper side of the fixing frame, and the output end of the electric push rod is fixedly connected to the upper side of the fixing frame.

[0012] Furthermore, two contact switches are embedded in the inner wall of the fixing frame, and the two contact switches are symmetrically fixedly connected to the inner wall of the fixing frame.

[0013] Furthermore, two sliders are fixedly connected to the side of the turntable, and a groove matching the sliders is provided inside the right side of the processing table.

[0014] Furthermore, the upper side of the turntable penetrates through the processing table and extends to its exterior.

[0015] Compared with the prior art, this utility model provides a carbon dioxide gas shielded welding wire rough drawing device, which has the following beneficial effects:

[0016] 1. This carbon dioxide gas shielded welding wire coarse drawing device can adjust the thickness of the welding wire through the welding wire adjustment device, thereby meeting the thickness requirements of welding wires with different carbon dioxide protection and expanding the range of welding wire application needs.

[0017] 2. This carbon dioxide gas shielded welding wire coarse drawing device uses a motor to drive the take-up rollers to collect the welding wire. In addition, the drive motor drives the turntable to rotate and exchange the positions of the two take-up rollers, which increases the amount of welding wire taken up. This solves the problem that the thickness of the welding wire in carbon dioxide gas shielded welding needs to be adjusted according to the welding requirements and conditions, and that it is impossible to guarantee the use requirements by using only one type of welding wire.

[0022] 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.

[0023] Please see Figures 1 to 3 This embodiment of a carbon dioxide gas shielded welding wire coarse drawing device includes a processing table 1. A fixing frame 6 is fixedly connected to the right end of the upper side of the processing table 1. A welding wire adjusting device 9 is provided inside the fixing frame 6. A rotating device is provided on the right side of the processing table 1. The welding wire adjusting device 9 includes a fixing frame 17 disposed inside the fixing frame 6, an upper threaded rod 18 sleeved on the left side of the fixing frame 17, two arc-shaped limiting plates 19 threadedly connected to the outer side of the threaded rod 18, and a left-end sliding rod 20 slidably sleeved on the lower side of the arc-shaped limiting plates 19. The rotating device includes a right-end drive motor 10 fixedly installed on the lower side of the processing table 1, a first bevel gear 11 fixedly connected to the output end of the drive motor 10, a second bevel gear 12 meshing with the upper side of the first bevel gear 11, a turntable 13 sleeved inside the second bevel gear 12, two motors 14 fixedly installed on the lower side of the turntable 13, and a take-up roller 16 fixedly connected to the output end of the motors 14.

[0024] The upper side of the processing table 1 is provided with a heating structure, which includes a left-end heating box 2 fixedly connected to the upper side of the processing table 1 and multiple heating wires 3 fixedly installed inside the heating box 2. The upper side of the processing table 1 is provided with a guide assembly, which includes a fixed frame 4 fixedly connected to the upper side of the processing table 1 and two transmission rollers 5 sleeved on the inner wall of the fixed frame 4. An electric push rod 7 is fixedly installed on the upper side of the fixed frame 6, and the output end of the electric push rod 7 is fixedly connected to the upper side of the fixed frame 17. Two contact switches 8 are embedded in the inner wall of the fixed frame 6 and are symmetrically fixedly connected to the inner wall of the fixed frame 6. Two sliders 15 are fixedly connected to the side of the turntable 13. A sliding groove matching the slider 15 is opened inside the right side of the processing table 1. The upper side of the turntable 13 penetrates the processing table 1 and extends to its outside.

[0025] The working principle of the above embodiments is as follows:

[0026] The welding wire passes through the heating wire 3 inside the heating box 2 to soften it. It then passes between the two drive rollers 5 and into the guide wire adjusting device 9. The wire thickness is adjusted according to the required thickness. Rotating the threaded rod 18 clockwise moves the two threaded arc-shaped limiting plates 19 closer together. The welding wire becomes thinner as it passes through the arc-shaped limiting plates 19, and vice versa. The wire is then wound around the upper side of the take-up roller 16. The motor 14 is started to drive the take-up roller 16 to wind the welding wire, while the electric push... Rod 7 pushes the welding wire adjusting device 9 to move downward within the fixed frame 6. When it contacts the contact switch 8 inside the fixed frame 6, it will move in the opposite direction, causing the welding wire to move up and down and reciprocate to wind at different heights on the take-up roller 16. When the welding wire is wound on the outside of one of the take-up rollers 16, the drive motor 10 drives the first bevel gear 11 to mesh with the second bevel gear 12 to drive the turntable 13 to rotate. The two upper take-up rollers 16 exchange positions, and the remaining welding wire is wound on the outside of the new take-up roller 16, increasing the amount of welding wire wound.
