Description

Technical Field

[0001] This invention relates to the technical field of material refining equipment, and specifically to an auxiliary device for industrial silicon smelting. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Welding has a wide range of applications, applicable to both metals and non-metals. Welding technology is primarily used on metal base materials, and commonly used methods include electric arc welding, argon arc welding, laser welding, and electroslag pressure welding. Non-metallic materials such as plastics can also be welded.

[0003] Existing welding pretreatment requires grinding away rust and dirt at the joints to prevent incomplete welding that would reduce the connection strength. The cleaning method usually involves sandpaper, which is inefficient and not suitable for steel plates of different thicknesses. The grinding position needs to be changed multiple times at different weld joints, resulting in inconsistent construction quality and hindering the improvement of construction efficiency.

A wedge-shaped block is provided at the end of the connecting frame away from the rotating fastener. The wedge-shaped blocks on the two sets of adjustment mechanisms have opposite inclined surfaces and are fixedly connected to the outside of the clamping plates.

[0013] In one embodiment, the power component includes an extension fixing frame, which has an L-shaped structure. One end of the extension fixing frame is fixed to the middle of the rectangular buckle block, and a rotating column is provided at the end of the extension fixing frame away from the rectangular buckle block. The rotating column is rotatably connected to the extension fixing frame, and a tapered groove rotating wheel is provided in the middle of the rotating column.

[0014] In one embodiment, the conical groove rotating wheel has a double-cone symmetrical inverted structure, and the central radius of the conical groove rotating wheel gradually increases from the middle to both ends.

[0015] In one embodiment, the cleaning component includes a fixed buckle frame disposed in the middle of two sets of rectangular buckle blocks. An extension frame is provided in the middle of the fixed buckle frame, with one end of the extension frame fixedly connected to the fixed buckle frame. A through-hole rotating groove is provided at the end of the extension frame away from the fixed buckle frame. Movable rockers are provided on both sides of the rotating groove. Two sets of movable rockers are located between two sets of conical groove rotating wheels. The middle of each movable rocker is rotatably connected to both sides of the rotating groove. A friction plate is provided in the middle of each movable rocker. Two sets of rotating fixed plates are provided at both ends of the friction plate. The friction plate is rotatably connected to the two sets of rotating fixed plates located in the middle of the movable rocker.

[0016] In one embodiment, the cleaning component further includes two sets of friction pads disposed on opposite sides of the two sets of friction plates, and a thrust plate is provided in the middle of the side of the clamping plate near the friction plates. The two sets of thrust plates clamp the two sets of friction plates.

[0017] In one embodiment, the processing mechanism further includes two sets of connecting members. Each connecting member includes a rectangular movable groove at both ends of the movable rocker. The movable rocker also has movable sliders at both ends. The movable sliders have a C-shaped structure and a sliding rod at the end of each movable slider. The sliding rods at both ends of the movable sliders are fastened to the rectangular movable grooves on the same side of the two sets of movable rocker. A power guide rod is provided on one side of the sliding rod of the movable slider. One end of the power guide rod is rotatably connected to the movable slider. The end of the power guide rod away from the movable slider is provided with a connecting fixing rod. The connecting fixing rod is rotatably connected to the periphery of one side of the conical groove rotating wheel.

[0018] In one embodiment, the two sets of connecting fixing rods are connected axially symmetrically at the position of the tapered groove rotating wheel.

[0019] The beneficial effects of this invention are as follows: This invention is a welding pretreatment device for wrapping hydrogen storage tank layers, which can adapt to different steel plate thicknesses, has high construction efficiency and standardization, and is adaptable to different welding linearities. Its specific implementation method is shown below:

[0020] After the operator places the equipment on one side of the weld, he pulls the rotating buckle to fasten the clamping plate to both sides of the shelf, so that the auxiliary wheel contacts the surface of the steel plate. Due to the elastic force of the elastic rod, the auxiliary wheel is smoothly attached to the shelf by the auxiliary guard plate. At the same time, the two sets of conical groove rotating wheels are inserted between the two sides of the weld. The inclined surface of the conical groove rotating wheel can prevent the equipment from falling off the shelf during polishing.

[0021] Then, pull the rotating buckle block to rotate at the movable cylinder, so that the clamping buckle block on the rotating buckle block contacts the inclined surface of the inclined wedge block, and squeezes the inclined wedge block to drive the connecting frame to move downward along the guide direction of the movable cylinder and the movable groove, and continues to push the thrust plate downward. At the same time, the friction pads on the rotating friction plates on both sides of the shelf plate are attached to the two sides of the shelf plate to achieve the initial fixation of the equipment.

[0022] After completion, continue pushing the rotating buckle. The conical groove rotating wheel rotates due to the friction of the shelf side, which in turn drives the connecting fixing rod to rotate. As the connecting fixing rod rotates, it drives the connected movable slider to slide in the rectangular movable groove on the movable rocker. Since the positions of the conical groove rotating wheels connected to the power guide rods on both sides of the rectangular movable groove are opposite, the movable rocker drives the movable rocker to swing left and right at the connection of the extension frame while the movable slider slides in the rectangular movable groove. This continues to drive the friction plate to swing the friction pad to polish the edge of the weld. The two sides of the weld are swung and rubbed multiple times, which greatly improves the polishing efficiency. At the same time, the movable rotating groove can also prevent the shelf of different thicknesses from having a collision with the friction plate during the polishing process.

[0023] After polishing, the rotating buckle continues to rotate in the opposite direction. The connecting frame is pushed by the pressure spring to expand the clamping plate. At the same time, the friction plate is driven by the torsion spring to continue to expand on both sides, so that the equipment peels off the layer plate and completes the pretreatment of the weld.

[0024] The equipment has a simple structure. It uses the friction between the conical groove rotating wheel and the weld seam to drive the friction plate to perform repeated wiping motion, which effectively solves the polishing problem of different weld seam lines. At the same time, the spacing between the two sides of the clamping plate can be adjusted by the adjustment mechanism to adapt to the pretreatment of plates of different thicknesses. It has good practicality and economy, which is conducive to the promotion and use of the equipment. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments.

A rotating shaft 23 is provided between the two sets of fixing blocks 22. Below the rotating shaft 23 are two sets of main guard plates 24, which are inserted into and symmetrically arranged inside the movable window 11. Auxiliary guard plates 25 are provided on both sides of the rotating shaft 23 of the two sets of auxiliary wheels 21. The two ends of the auxiliary guard plates 25 are rotatably connected to the rotating shaft 23 of the two sets of auxiliary wheels 21. One of the auxiliary wheels 21... The wheel 21 has main guard plates 24 on both sides of the rotating shaft 23. One end of the main guard plate 24 is rotatably connected to the auxiliary wheel 21, and the end of the main guard plate 24 away from the rotating shaft 23 is rotatably connected to the rotating shaft 23. The auxiliary guard plate 25 also has an elastic rod 26 at the end away from the main guard plate 24. One end of the elastic rod 26 is rotatably connected to the auxiliary guard plate 25. The attached drawing uses an exaggerated drawing style and is not the actual scale of the structure. It is only used for comparison of the connection position. The other end of the elastic rod 26 is rotatably connected to the end of the main guard plate 24 away from the auxiliary guard plate 25.

[0039] In practice, the auxiliary wheel 21 is subjected to the elastic force of the elastic rod 26, and the auxiliary guard plate 25 smoothly attaches the two sets of auxiliary wheels 21 to the shelf. At the same time, the weld seams are passed between the two sets of conical groove rotating wheels 45. The inclined surface of the conical groove rotating wheel 45 can prevent the equipment from detaching from the shelf during polishing.

[0040] Reference Figure 2 , 3 As shown, the adjustment mechanism 3 is located on one side of the two sets of clamping plates 1 to assist in clamping the clamping plates 1. The adjustment mechanism 3 includes two sets of rotating fasteners 31, which are symmetrically arranged. The rotating fasteners 31 are located on one side of the two sets of clamping plates 1 and have a C-shaped structure. The ends of the rotating fasteners 31 are provided with pressing fasteners 32, and the middle of the rotating fasteners 31 is provided with a movable cylinder 361.

A pressure spring 36 is provided between the two sets of connecting frames 33 and is slidably connected to the movable cylinder 361. A wedge block 34 is provided at the end of the connecting frame 33 away from the rotating buckle 31. The wedge blocks 34 on the two sets of adjustment mechanisms 3 have opposite inclined surfaces and are fixedly connected to the outside of the clamping plate 1.

[0041] In practice, the rotating buckle 31 is pulled to rotate at the movable cylinder 361, so that the pressing buckle 32 on the rotating buckle 31 contacts the inclined surface of the inclined wedge block 34, and the inclined wedge block 34 is squeezed to drive the connecting frame 33 to move downward along the guide direction of the movable cylinder 361 and the movable groove 351, and continue to push the thrust plate 12 downward to squeeze. At the same time, the friction pads 471 on the rotating friction plates 47 on both sides of the shelf plate are attached to the two sides of the shelf plate.

[0042] Reference Figure 4 , 5 As shown in Figure 6, the processing mechanism 4 is located between the adjustment mechanism 3 and the clamping plate 1. The processing mechanism 4 includes a power component and a cleaning component. The power component includes an extension fixing frame 452, which has an L-shaped structure. One end of the extension fixing frame 452 is fixed to the middle of the rectangular buckle block 35. The end of the extension fixing frame 452 away from the rectangular buckle block 35 is provided with a rotating column 451, which is rotatably connected to the extension fixing frame 452. The middle of the rotating column 451 is provided with a conical groove rotating wheel 45, which has a double-cone symmetrical inverted structure. The center radius of the conical groove rotating wheel 45 gradually increases from the middle to both ends.

[0043] As can be seen, the tapered groove rotating wheel 45 can assist in fastening to the weld of the steel plate to be treated, preventing it from falling off, and at the same time, it can adapt to welding of different edge arcs;

[0044] The cleaning component includes a fixed fastener 41, which is located in the middle of two sets of rectangular fastener blocks 35. An extension frame 42 is located in the middle of the fixed fastener 41, with one end of the extension frame 42 fixedly connected to the fixed fastener 41. A through-hole movable rotating groove 421 is located at the end of the extension frame 42 away from the fixed fastener 41. Movable rockers 43 are located on both sides of the movable rotating groove 421, with two sets of movable rockers 43 positioned between two sets of conical groove rotating wheels 45. The middle of each movable rocker 43 is rotatably connected to both sides of the movable rotating groove 421. A friction plate 47 is located in the middle of each movable rocker 43, with friction plates at both ends. There are two sets of rotating fixed plates 48. Friction plates 47 are rotatably connected to the two sets of rotating fixed plates 48 located in the middle of the movable rocker 43. A torsion spring 481 is provided between one side of the friction plate 47 and the rotating fixed plates 48 located at both ends of the movable rocker 43. The cleaning component also includes two sets of friction pads 471. The friction pads 471 are located on the opposite sides of the two sets of friction plates 47. The friction pads 471 can be replaced by grinding wheels or other grinding tools. It is only necessary to achieve the grinding function. A thrust plate 12 is provided in the middle of the side of the clamping plate 1 near the friction plate 47. The two sets of thrust plates 12 clamp the two sets of friction plates 47.

[0045] In practice, the tapered groove rotating wheel 45 rotates due to the friction of the side of the plate, which in turn drives the connecting fixing rod 46 to rotate. As the connecting fixing rod 46 rotates, it drives the connected movable slider 44 to slide in the rectangular movable groove 431 on the movable rocker plate 43. While the movable slider 44 slides in the rectangular movable groove 431, it drives the movable rocker plate 43 to swing left and right at the connection of the extension frame 42, which in turn drives the friction plate 47 to swing the friction pad 471 to polish the edge of the weld.

[0046] Beneficially, the processing mechanism 4 also includes two sets of connecting parts. The connecting parts include rectangular movable grooves 431 located at both ends of the movable rocker 43. Movable sliders 44 are also located at both ends of the movable rocker 43. The movable sliders 44 have a C-shaped structure and a sliding rod at the end of the movable sliders 44. The sliding rods at both ends of the movable sliders 44 are fastened to the rectangular movable grooves 431 located on the same side of the two sets of movable rocker 43. A power guide rod 461 is located on one side of the sliding rod of the movable slider 44. One end of the power guide rod 461 is rotatably connected to the movable slider 44. A connecting fixing rod 46 is located at the end of the power guide rod 461 away from the movable slider 44. The connecting fixing rod 46 is rotatably connected to the outer periphery of one side of the conical groove rotating wheel 45. The two sets of connecting fixing rods 46 are connected to the conical groove rotating wheel 45 in an axially symmetrical manner.

[0047] Working principle of this invention:

[0048] After the operator places the equipment on one side of the weld, he pulls the rotating buckle to fasten the clamping plate to both sides of the shelf, so that the auxiliary wheel contacts the surface of the steel plate. Due to the elastic force of the elastic rod, the auxiliary wheel is smoothly attached to the shelf by the auxiliary guard plate. At the same time, the two sets of conical groove rotating wheels are inserted between the two sides of the weld. The inclined surface of the conical groove rotating wheel can prevent the equipment from falling off the shelf during polishing.

[0049] Then, pull the rotating buckle block to rotate at the movable cylinder, so that the clamping buckle block on the rotating buckle block contacts the inclined surface of the inclined wedge block, and squeezes the inclined wedge block to drive the connecting frame to move downward along the guide direction of the movable cylinder and the movable groove, and continues to push the thrust plate downward. At the same time, the friction pads on the rotating friction plates on both sides of the shelf plate are attached to the two sides of the shelf plate to achieve the initial fixation of the equipment.

[0050] After completion, continue pushing the rotating buckle. The conical groove rotating wheel rotates due to the friction of the shelf side, which in turn drives the connecting fixing rod to rotate. As the connecting fixing rod rotates, it drives the connected movable slider to slide in the rectangular movable groove on the movable rocker. Since the positions of the conical groove rotating wheels connected to the power guide rods on both sides of the rectangular movable groove are opposite, the movable rocker drives the movable rocker to swing left and right at the connection of the extension frame while the movable slider slides in the rectangular movable groove. This continues to drive the friction plate to swing the friction pad to polish the edge of the weld. The two sides of the weld are swung and rubbed multiple times, which greatly improves the polishing efficiency. At the same time, the movable rotating groove can also prevent the shelf of different thicknesses from having a collision with the friction plate during the polishing process.

[0051] After polishing, the rotating buckle continues to rotate in the opposite direction. The connecting frame is pushed by the pressure spring to expand the clamping plate. At the same time, the friction plate is driven by the torsion spring to continue to expand on both sides, so that the equipment peels off the layer plate and completes the pretreatment of the weld.

[0052] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.
