Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to a welding forming device for a molten steel sampler. Background Technology

[0002] A molten steel sampler is a tool used to extract samples from molten steel, widely used in smelting processes such as electric furnaces, converters, continuous casting, and secondary refining. Current technology allows for laser welding during sampler manufacturing to strengthen connections and seals, while also facilitating sample removal. However, this process relies on manual labor, resulting in relatively low production efficiency. A highly automated device that significantly improves processing efficiency is lacking. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a welding and forming device for a molten steel sampler.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a welding and forming device for a molten steel sampler, comprising a feeding mechanism for receiving and conveying materials, a welding mechanism for laser welding workpieces, a transfer mechanism for carrying and circumferentially rotating workpieces, and a material transfer mechanism for clamping and transferring materials. The material transfer mechanism includes a pair of pneumatic clamp assemblies and a transverse guide rail. A support frame is fixedly connected below the transverse guide rail. The pneumatic clamp assemblies slide and cooperate with the transverse guide rail to reciprocate horizontally. The transfer mechanism includes a mounting frame, a servo motor, a coupling, and a positioning seat. The mounting frame has a vertically penetrating mounting hole in the center. The servo motor, coupling, and positioning seat are sequentially assembled on the mounting frame along the axis of the mounting hole.

[0016] like Figures 1-3 As shown, a welding and forming device for a molten steel sampler includes a feeding mechanism 1 for receiving and conveying materials, a welding mechanism 2 for laser welding workpieces, a transfer mechanism 3 for carrying and circumferentially rotating workpieces, and a transfer mechanism 4 for clamping and transferring materials. During processing, the workpiece first enters the feeding mechanism 1, which then conveys it to the movement trajectory of the transfer mechanism 4, where it is transferred to a designated position. Specifically, the workpiece is transferred to the transfer mechanism 3, where it undergoes step-by-step rotation, and the welding mechanism 2 performs multi-point welding to achieve a closed connection. It should be noted that the welding mechanism 2 is a mature technology, and therefore will not be elaborated upon or limited here.

[0017] The material transfer mechanism 4 includes a pair of pneumatic clamp assemblies 5 and a transverse guide rail 6. A support frame 7 is fixedly connected below the transverse guide rail 6. The pneumatic clamp assembly 5 slides and reciprocates horizontally with the transverse guide rail 6. The pneumatic clamp assembly 5 has a slider that engages with the transverse guide rail 6; the connection between the two is a mature technology. The material transfer mechanism 3 includes a mounting frame 8, a servo motor 9, a coupling 10, and a positioning seat 11. The mounting frame 8 has a vertically penetrating mounting hole in its center. The servo motor 9, coupling 10, and positioning seat 11 are sequentially assembled on the mounting frame 8 along the axis of the mounting hole. The mounting frame 8 provides limiting assembly and relative stability. Simultaneously, the width of the positioning seat 11 is greater than the diameter of the mounting hole, allowing the positioning seat 11 to directly press against the surface of the mounting frame 8 for stability. The positioning seat 11 is provided with a positioning groove 12 for placing the workpiece. The positioning seat 11 also has an initial positioning groove 13 and a spare groove 14 that penetrate the positioning groove 12. The initial positioning groove 13 and the spare groove 14 are perpendicular to each other along their respective lengths. The positioning seat 11 also has movable grooves 15 at at least the four corners of the positioning groove 12 for the air clamp assembly 5 to extend into. The initial positioning groove 13 corresponds to the initial orientation and state of the workpiece, thus its shape design is well-matched. The spare groove 14 is designed to facilitate the removal of the workpiece in case of jamming or special circumstances, and can also serve as an open channel for infrared sensors to monitor the workpiece, depending on actual needs. It should be noted that, for greater practicality, the initial positioning groove 13 and the spare groove 14 both penetrate the entire positioning seat 11. Their perpendicularity also corresponds to the welding points and facilitates the design of monitoring points. The movable groove 15 is designed to facilitate the clamping and transfer of the air clamp assembly 5 without hindering workpiece positioning.

[0018] The pneumatic clamp assembly 5 includes a longitudinal guide rail 16, a connecting seat 17, and a pair of clamps 18. The clamps 18 have a Y-shaped structure, and the longitudinal guide rail 16 and the connecting seat 17 are slidably fitted together. The pneumatic clamp assembly 5 mainly utilizes pneumatic principles for clamping, which is a mature technology. The key difference lies in the structural design of the clamps 18, which is tailored to specific workpieces. The longitudinal guide rail 16 is designed similarly; its assembly and fit will not be elaborated upon further. The main point is that the fit between the longitudinal guide rail 16 and the transverse guide rail 6 allows the pneumatic clamp assembly 5 to move at any point in the longitudinal plane, facilitating workpiece clamping and transfer within a certain range. The Y-shaped structure of the clamps 18 helps to reduce the size of the clamping part 19, utilizing the characteristics of the movable fork to clamp materials.

[0019] The chuck 18 has clamping portions 19 at opposite ends. The clamping portions 19 between the chucks 18 are curved towards each other, and the clamping portions 19 have abutment surfaces 20 on their opposite surfaces. The abutment surfaces 20 are specially designed to improve the clamping effect, better fit the workpiece surface, and increase the contact area and stability. The abutment surfaces 20 are arc-shaped, and a vertically penetrating groove 21 is also provided on the abutment surfaces 20. In this embodiment, the workpiece surface is mainly annular, allowing for a closer fit. A cutting edge is designed near the edge to mate with the workpiece body and handle, depending on the specific production and usage. Alternatively, the chuck 18 can be designed as an elastic part at this location to enhance the clamping effect on the workpiece; however, this will not be elaborated upon further. The groove 21 is a fan-shaped structure with a central angle greater than 90 degrees, making it more targeted. The projection of the movable groove 15 in the vertical direction is a rounded shape, meaning that the edges and corners have been rounded. In this embodiment, the inner side of the movable groove 15 is arc-shaped, but this is not the only limitation.

[0020] The feeding mechanism 1 includes a conveying cylinder 22, a slide 23, and a conveying seat 24. The slide 23 and the conveying seat 24 are slidably coupled, and the slide 23 is linked to the output end of the conveying cylinder 22. The conveying cylinder 22 is fixedly assembled to the conveying seat 24. In this embodiment, the feeding mechanism 1 can be used in conjunction with other conveying mechanisms for effective connection. The slide 23 is provided with several positioning posts 25 corresponding to the contour of the workpiece. The positioning posts 25 themselves provide a coarse positioning of the workpiece, limiting the position of the workpiece within a certain accuracy range, which facilitates the clamping and transfer of the pneumatic clamping assembly 5. At the same time, the design of the positioning posts 25 also provides sufficient space for the movement of the pneumatic clamping assembly 5, avoiding interference.
