Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing technology, and in particular to a radial wire drawing device for the surface of metal parts. Background Technology

[0002] Metal surface brushing technology can be used to create several patterns such as straight lines, random lines, spirals, wavy lines, and swirls, depending on the decorative needs. In recent years, more and more products have used metal brushing technology on their metal casings to achieve aesthetic appeal and corrosion resistance, giving the products both fashion and technological elements.

[0003] As shown in the reference case "Sunburst Wire Drawing Machine" (publication number CN219075234U), it includes a main frame, a workpiece transmission assembly, an automatic control console, a chuck, tooling and grinding mechanism, and a slide assembly and drive assembly. The drive assembly is located on the top end face of the main frame and includes a vertical linear drive mechanism and a horizontal linear drive mechanism connected to it. The slide assembly is located above the main frame via the horizontal linear drive mechanism. The grinding mechanism is mounted on the slide assembly and can move between positions close to and away from the tooling. This invention, by adding a slide assembly, a vertical linear drive mechanism, and a horizontal linear drive mechanism, allows the position of the grinding mechanism to be arbitrarily adjusted in both the vertical and horizontal directions, thus facilitating the processing of workpieces of various thicknesses. It features time and labor savings and improved processing efficiency.

[0004] However, the aforementioned wire drawing machine generates a large amount of metal shavings during use due to the grinding action, and the friction also produces high temperatures. If these shavings are not collected in a timely and effective manner, they easily adhere to the surface of the parts or the wire drawing tools, causing defects such as scratches and unevenness in the processed texture. Furthermore, excessively high temperatures can also cause the surface of the parts to oxidize and discolor, affecting their appearance. Utility Model Content

[0005] Therefore, it is necessary to provide a radial wire drawing device for the surface of metal parts to address the problems of debris collection and frictional heating.

[0006] A radial wire drawing device for the surface of metal parts includes: a frame, on the surface of which a wire drawing mechanism and a rotating mechanism are respectively mounted; the rotating mechanism includes a motor fixedly connected to the top of the frame, and a fixing block fixedly connected to the output shaft end of the motor; a debris collection mechanism disposed on the frame, the debris collection mechanism including an inner cover fixedly connected to the top of the frame, an outer cover fixedly connected to the bottom of the inner cover, the inner cover being conical and having a through hole at the top, the outer cover being open at the top, a liquid pump mounted at the bottom of the outer cover, a lifting plate mounted on the wire drawing mechanism, a spray pipe fixedly connected to the lifting plate, and a flexible hose connecting the outlet of the liquid pump to the spray pipe.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5This invention describes a radial wire drawing device for the surface of metal parts.

[0026] In one embodiment, a radial brushing apparatus for the surface of a metal component includes:

[0027] A frame 100 is provided, and a wire drawing mechanism 200 and a rotating mechanism 300 are respectively mounted on the surface of the frame 100. The rotating mechanism 300 includes a motor 310 fixedly connected to the top of the frame 100, and a fixing block 320 is fixedly connected to the output shaft end of the motor 310.

[0028] The debris collection mechanism 400 is mounted on the frame 100. The debris collection mechanism 400 includes an inner cover 410 fixedly connected to the top of the frame 100, and an outer cover 420 fixedly connected to the bottom of the inner cover 410. The inner cover 410 is conical and has a through hole 430 at the top. The outer cover 420 is open at the top and has a liquid pump 440 installed at the bottom of the outer cover 420. A lifting plate is mounted on the wire drawing mechanism 200, and a spray pipe 450 is fixedly connected to the lifting plate. The outlet of the liquid pump 440 and the spray pipe 450 are connected by a hose.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, a sanding belt is installed at the bottom of the lifting plate, and the spray pipe 450 is oriented towards the sanding belt. A liquid-blocking support plate 460 is fixedly connected to the bottom of the fixing block 320. The through hole 430 is clearance-fitted with the output shaft of the motor 310, and the diameter of the liquid-blocking support plate 460 is larger than the diameter of the through hole 430. A connecting pipe 470 is fixedly connected to the bottom of the outer cover 420, and the connecting pipe 470 is connected to the inlet of the liquid pump 440.

[0030] In this embodiment, the inner cover 410 and the outer cover 420 form a relatively enclosed processing space. When the metal parts rotate on the fixed block 320 with the motor 310, and the sanding belt contacts the surface of the parts for wire drawing, the spray pipe 450 sprays coolant into the contact area between the sanding belt and the parts to cool the metal parts and ensure the cooling effect. At the same time, the coolant can also flush away debris, washing it off the surface of the parts. Meanwhile, the liquid-blocking support plate 460 can prevent the coolant from flowing downward along the output axis of the motor 310, preventing water from entering and damaging the motor 310. Its design, with a diameter larger than the through hole 430, can guide the splashed coolant to the outside of the inner cover 410, and then collect it into the outer cover 420 through the conical inclined wall. The upper opening of the outer casing 420 is configured to work with the liquid pump 440 and the connecting pipe 470 to circulate the coolant. The coolant mixed with debris enters the liquid pump 440 through the connecting pipe 470 and is then sprayed out again through the spray pipe 450. This not only improves the utilization rate of the coolant, but also forces the debris into the outer casing 420 for collection through the liquid flow, reducing debris splashing and facilitating debris collection.

[0031] It should be noted that the wire drawing mechanism 200 includes a radial drive assembly and a lifting drive assembly. The radial drive assembly, mounted on the top of the frame 100, consists of a cylinder, a positioning rod, and a moving seat. The cylinder drives the moving seat to move along the surface of the positioning rod, which in turn drives the lifting drive assembly to move, thereby causing the sanding belt to move radially along the workpiece. This ensures a smooth and stable trajectory for the sanding belt as it moves from the center of the workpiece to its edge, guaranteeing the uniformity of the radial texture.

[0032] The lifting drive assembly adopts a cylinder structure, with its cylinder body fixed on the movable seat of the radial drive assembly, and its telescopic end connected to the top of the lifting plate. The air intake of the cylinder is controlled by a solenoid valve, enabling rapid lifting and precise positioning of the lifting plate. When the sanding belt needs to contact or detach from the surface of the part, the cylinder can respond quickly, avoiding ineffective contact between the sanding belt and the part when it is not being processed.

[0033] The radial drive assembly and the lifting drive assembly of the wire drawing mechanism 200 are linked through the control system. After the sanding belt completes one radial movement from the center to the edge, the lifting drive assembly drives the sanding belt to rise, and the radial drive assembly drives the lifting plate to reset above the center of the part. Then the lifting drive assembly drives the sanding belt to descend to perform the next wire drawing operation.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the outer cover 420 has a limiting groove corresponding to the connecting pipe 470, and a filter basket 480 is installed in the limiting groove. The bottom of the inner wall of the outer cover 420 has an inclined guide surface, which slopes downwards from the inner wall towards the center. The connecting pipe 470 connects to the lowest point of the inclined guide surface. The height of the outer cover 420 is higher than the height of the metal parts after they are placed on top of the fixing block 320. The outer cover 420 is a transparent acrylic cover. The inner cover 410 is positioned above the motor 310 but does not contact the top of the motor 310. The inner cover 410 is coaxially aligned with the motor 310.

[0035] In this embodiment, the filter basket 480 filters the coolant entering the connecting pipe 470, intercepting metal debris and preventing it from entering the pump 440 and causing equipment wear. It also facilitates periodic removal and cleaning of the debris. The inclined guide surface on the inner wall of the outer cover 420 accelerates the flow of coolant and debris towards the connecting pipe 470, improving collection efficiency. The transparent acrylic outer cover 420 allows operators to observe the processing status and debris accumulation in real time. Its height can surround rotating metal parts, preventing coolant and debris from being thrown out of the processing area. The inner cover 410 is coaxial with the motor 310 but not in contact with it. It works in conjunction with the liquid-blocking support plate 460 to guide the coolant flow, preventing water ingress and damage to the motor 310. Without affecting the rotation of the motor 310, the tapered inner cover 410 allows for better flow of coolant into the connecting pipe 470 for filtration and circulation.

[0036] Working Principle: The metal parts are fixed to the top of the fixing block 320. The motor 310 is started, causing the fixing block 320 and the parts to rotate synchronously. The wire drawing mechanism 200 drives the lifting plate to descend, so that the sanding belt contacts the center point of the parts. Then, the sanding belt moves radially outward, forming radial patterns in conjunction with the rotation of the parts. During the processing, the liquid pump 440 draws coolant from the outer cover 420 through the connecting pipe 470 and sprays it onto the contact point between the sanding belt and the parts through the spray pipe 450, achieving cooling while flushing away debris. The coolant and debris flow into the outer cover 420 under the guidance of the liquid baffle support plate 460 and the inner cover 410, and converge into the filter basket 480 through the inclined guide surface. The filtered coolant re-enters the connecting pipe 470 for circulation. After the wire drawing is completed, the wire drawing mechanism 200 resets, and the parts continue to rotate to dry the residual coolant on the surface. The outer cover 420 collects and recovers the splashed coolant, finally completing one radial pattern wire drawing process.

[0037] It should be noted that the motor 310 and the liquid pump 440 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the motor 310 and the liquid pump 440 can be powered by mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
