Description

Technical Field

[0001] This invention relates to the field of wheel hub cover wire drawing equipment, and in particular to a wheel hub cover wire drawing equipment and wire drawing process. Background Technology

[0002] Wheel hubcaps, commonly known as wheel covers, are an important component of car wheels, and their surface texture directly affects the overall appearance of the vehicle. Currently, some car manufacturers design curved shapes on wheel hubcaps to enhance their aesthetics. A well-designed curved structure not only improves the overall appearance of the vehicle but also helps maintain better stability during cornering and high-speed driving.

[0003] In the surface treatment process of wheel hub covers, brushing is an important means to enhance the metallic texture and decorative effect, and it is widely used in the processing of metal covers. Currently, the commonly used method is distributed brushing. First, a CNC machine tool is used to perform preliminary brushing on the end face of the cover. Then, manual polishing is carried out on the complex curved surface by hand using tools such as hand-held angle grinders with sandpaper or sanding belts, gradually transitioning from coarse grit to fine grit to complete the overall surface texture treatment.

[0004] However, in the existing technology, especially when processing wheel hub covers with curved or complex surfaces, the sandpaper or sanding belt does not produce a uniform bristle effect on the curved surface, which affects the final surface treatment quality. Summary of the Invention

[0005] Therefore, it is necessary to provide a wheel hub cover wire drawing device to address the problem of uneven wire drawing effect when grinding the arc surface of the wheel hub cover.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A wheel hub cover wire drawing device, comprising:

[0008] support;

[0009] A grinding belt is rotatably mounted on the bracket and is used to perform a wire-brushing treatment on the surface of the wheel hub cover plate; the thickness of the middle part of the grinding belt is less than the thickness of the two sides of the grinding belt.

[0010] A clamping band is rotatably mounted on the bracket, and the clamping band has a transitional arc structure that is high in the middle and low at both ends;

[0011] When the grinding belt performs wire drawing on the convex surface of the wheel hub cover, the clamping belt can reduce the pressure concentration of the middle part of the grinding belt on the top of the convex surface of the wheel hub cover;

[0012] When the grinding belt performs wire drawing on the concave surface of the wheel hub cover, the clamping belt enables the grinding belt to fit tightly against the concave surface of the wheel hub cover.

[0013] Furthermore, the polishing belt includes a first sanding belt and a second sanding belt. One end face of the first sanding belt has a first wave structure, and one end face of the second sanding belt has a second wave structure. The first wave structure and the second wave structure are interleaved and abut against each other.

[0014] Furthermore, the support includes a first support, a second support, and multiple sets of support wheels, with the first support and the second support hinged together; at least two sets of support wheels are rotatably mounted on the first support, and at least one set of support wheels is rotatably mounted on the second support; both the first and second sanding belts are sleeved on the multiple sets of support wheels, and each set of support wheels has a first placement position for preventing the first and second sanding belts from detaching from the support wheels; the clamping belt is sleeved on the multiple sets of support wheels; each set of support wheels has a second placement position for accommodating the clamping belt, and the second placement position is closer to the central axis of the support wheel than the first placement position.

[0015] Furthermore, the mesh count of the first abrasive belt is different from that of the second abrasive belt.

[0016] Furthermore, it also includes an adjustment mechanism and a tensioning mechanism. The adjustment mechanism is used to adjust the opening angle of the first support and the second support; the tensioning mechanism is used to maintain the tension of the pressing belt, the first sanding belt and the second sanding belt.

[0017] Furthermore, the adjustment mechanism includes a toggle lever and an adjustment lever. The adjustment lever is slidably disposed inside the first bracket, and one end of the adjustment lever abuts against the second bracket. The toggle lever is vertically fixedly connected to the adjustment lever, and the toggle lever is slidably connected to the first bracket. By adjusting the position of the toggle lever, the overlap area between the adjustment lever and the first bracket can be changed to adjust the opening angle of the first bracket and the second bracket.

[0018] Furthermore, the adjustment mechanism also includes a first spring and a fixing nut. One end of the first spring is fixedly connected to the first bracket, and the other end is fixedly connected to the second bracket. The fixing nut is rotatably connected to the actuating rod on the same axis, and the fixing nut is used to fix the actuating rod. The elastic force of the first spring cooperates with the adjustment action of the fixing nut to maintain the opening angle of the first bracket and the second bracket.

[0019] Furthermore, the tensioning mechanism includes a fixed plate, a first tensioning block, a second tensioning block, and a tensioning wheel. The fixed plate is fixedly connected to the first bracket, and the first tensioning block is fixedly connected to the fixed plate. The second tensioning block is slidably connected to the first tensioning block, and the tensioning wheel is fixedly connected to the second tensioning block. The tensioning wheel is coaxially rotatably connected to a set of support wheels.

[0020] Furthermore, the tensioning mechanism also includes a second spring and a third spring. The second spring is disposed inside the first tensioning block, with one end fixedly connected to the first tensioning block and the other end fixedly connected to the second tensioning block. The elastic force of the second spring always causes the second tensioning block to tend to move away from the first tensioning block. The third spring is disposed outside the second tensioning block, with one end fixedly connected to the second tensioning block and the other end fixedly connected to the first tensioning block. The elastic force of the third spring is used to prevent the second tensioning block from disengaging from the first tensioning block.

[0021] The present invention also provides a wire drawing process for a wheel hub cover wire drawing device, applicable to any of the wheel hub cover wire drawing devices described above, comprising the following steps:

[0022] S100. Check the integrity of the installation of each component;

[0023] S200, The operator drives the grinding belt to move unidirectionally along the surface of the hub cover plate;

[0024] S300. When the grinding belt performs wire drawing on the convex surface of the wheel hub cover, the clamping belt can reduce the pressure concentration of the middle part of the grinding belt on the top of the convex surface of the wheel hub cover; when the grinding belt performs wire drawing on the concave surface of the wheel hub cover, the clamping belt can make the grinding belt fit tightly against the concave surface of the wheel hub cover.

[0025] The beneficial effects of this invention are:

[0026] This invention provides a wheel hub cover wire drawing device and a wire drawing process. The wheel hub cover wire drawing device includes a support, a grinding belt, and a clamping belt. The grinding belt is rotatably mounted on the support and is used to perform wire drawing on the wheel hub cover. The clamping belt is rotatably mounted on the support and has a transitional arc structure that is higher in the middle and lower at both ends. When the grinding belt performs wire drawing on the convex surface of the wheel hub cover, the clamping belt can reduce the pressure concentration at the top of the convex surface of the wheel hub cover by the middle of the grinding belt. When the grinding belt performs wire drawing on the concave surface of the wheel hub cover, the clamping belt can ensure that the grinding belt fits tightly against the concave surface of the wheel hub cover. Therefore, the clamping belt not only alleviates pressure concentration but also ensures the uniformity and consistency of the wire drawing process on the surface of the wheel hub cover.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0048] The following reference Figures 1 to 13 This invention describes a wheel hub cover wire drawing device provided in an embodiment of the invention.

[0049] like Figures 1 to 3 As shown, the wheel hub cover wire drawing equipment provided by the present invention is particularly suitable for wire drawing treatment of the surface of automobile wheel hub covers, and can also be used for wire drawing treatment under other working conditions under appropriate circumstances.

[0050] The wheel hub cover brushing equipment includes a support frame and a grinding belt. The grinding belt is a ring-shaped structure connected end to end and rotatably mounted on the support frame. The grinding belt is used to brush the wheel hub cover, and its thickness in the middle is less than the thickness on both sides. The wheel hub cover brushing equipment also includes an angle grinder 100, which provides power to the grinding belt, enabling it to brush the wheel hub cover and achieve a preset texture on the surface.

[0051] Specifically, the angle grinder 100 is started to drive the grinding belt, which is then pressed onto the surface of the wheel hub cover. Next, the operator holds the angle grinder 100 and moves it along a preset direction, causing the grinding belt to slide and brush along the surface of the wheel hub cover in the same direction. After completing one brushing stroke, instead of reversing the grinding path, the grinding belt is lifted off the surface of the wheel hub cover and returned to the starting position for the next unidirectional brushing operation. This ensures that the surface of the wheel hub cover is only subjected to brushing treatment in one direction, thus forming a uniform texture.

[0052] Furthermore, the wheel hub cover wire drawing equipment also includes a clamping belt 330. The clamping belt 330 is disposed inside the grinding belt and is rotatably mounted on a bracket. In addition, the clamping belt 330 has a transitional arc structure that is higher in the middle and lower at both ends, with its middle section bulging towards the first wave structure 311 and the second wave structure 321. Specifically, the surface of the wheel hub cover exhibits both convex and concave surfaces, and its structure is not a single planar form but rather displays a certain curvature variation.

[0053] When the grinding belt applies a wire-drawing process to the convex surface of the wheel hub cover, the thickness of the middle section of the grinding belt is less than that of its sides. Therefore, under certain pressure applied by the operator, the thinner middle section experiences less compression deformation, resulting in relatively lower contact pressure on the top of the convex surface. Furthermore, compared to a grinding belt with equal thickness in the middle and on both sides, which produces a greater wire-drawing effect on the top of the convex surface, the thinner middle section effectively reduces excessive wear, improving the uniformity and surface quality of the wire-drawing process. During this process, the clamping belt 330 continuously applies appropriate pressure to the middle of the grinding belt, which, combined with the operator's pressure on the equipment, ensures good contact between the middle of the grinding belt and the top of the convex surface of the wheel hub cover. This guarantees uniform and effective contact between the grinding belt and the wheel hub cover surface, ensuring consistent and uniform wire-drawing results.

[0054] When the grinding belt brushes the concave surface of the wheel hub cover, the concave structure can easily lead to poor adhesion between the belt and the surface, affecting the brushing effect. At this time, the transition arc structure of the clamping belt 330 complements the concave area. Simultaneously, combined with the operator's pressure on the equipment, the middle of the clamping belt 330 applies pressure towards the concave surface of the wheel hub cover, ensuring a tight fit between the grinding belt and the concave surface. This maintains effective contact between the grinding belt and the wheel hub cover surface, guaranteeing the consistency and uniformity of the brushing effect.

[0055] In one embodiment, the abrasive belt includes a first abrasive belt 310 and a second abrasive belt 320. One end face of the first abrasive belt 310 has a first wave structure 311, and one end face of the second abrasive belt 320 has a second wave structure 321. The first wave structure 311 and the second wave structure 321 are staggered and abut against each other.

[0056] In one embodiment, the support includes a first support 201, a second support 202, and multiple sets of support wheels 210. The first support 201 and the second support 202 are hinged together. At least two sets of support wheels 210 are rotatably mounted on the first support 201, with the two sets of support wheels 210 spaced apart. At least one set of support wheels 210 is rotatably mounted on the second support 202, cooperating with the support wheels 210 on the first support 201 to form a support structure for the first sanding belt 310 and the second sanding belt 320. The first sanding belt 310 and the second sanding belt 320 are together mounted on the two sets of support wheels 210 on the first support 201 and the one set of support wheels 210 on the second support 202, forming a stable transmission path. Furthermore, each set of support wheels 210 has a first placement position 211, which is used to prevent the first sanding belt 310 and the second sanding belt 320 from detaching from the support wheel 210.

[0057] Furthermore, the pressing band 330 is sleeved on multiple sets of support wheels 210, and each set of support wheels 210 has a second placement position 212 for accommodating the pressing band 330. The second placement position 212 can be understood as being formed by the central region of the first placement position 211 being recessed inward along the radial direction of the support wheel 210. That is, the region near both ends of the support wheel 210 is the first placement position 211, while the central region of the support wheel 210 is the second placement position 212. The second placement position 212 is closer to the central axis of the support wheel 210 than the first placement position 211.

[0058] Furthermore, the angle grinder 100 has an output rod that is coaxially and detachably connected to a support wheel 210 on the first bracket 201 near the hinge point of the first bracket 201 and the second bracket 202.

[0059] Specifically, the angle grinder 100 is started, driving the output rod to rotate around its own axis, thereby causing the support wheel 210 connected to the output rod to rotate synchronously, further driving the first sanding belt 310 and the second sanding belt 320 to rotate synchronously on the support wheel 210. Then, the first sanding belt 310 and the second sanding belt 320 are pressed onto the surface of the hub cover plate to begin the wire drawing process. When the first sanding belt 310 and the second sanding belt 320 are drawing the convex surface of the hub cover plate, the structure of the convex surface of the hub cover plate itself, the pressure applied by the operator to the equipment, and the inherent elasticity of the first sanding belt 310 and the second sanding belt 320 cause them to slide away from each other along both sides of the convex surface of the hub cover plate as they pass over the top of the convex surface. Consequently, the first wave structure 311 and the second wave structure 321 also tend to move away from each other. During this process, the first sanding belt 310 and the second sanding belt 320 will undergo appropriate deformation, which increases the distance between the first wave structure 311 and the second wave structure 321, thereby reducing the contact area between the first sanding belt 310 and the second sanding belt 320 and the top of the convex surface of the hub cover plate, thus effectively alleviating the local pressure concentration on the surface of the hub cover plate caused by the first sanding belt 310 and the second sanding belt 320.

[0060] Meanwhile, as the first sanding belt 310 and the second sanding belt 320 slide away from each other due to contact with the top of the convex surface of the hub cover plate, the first wave structure 311 and the second wave structure 321 will experience a certain degree of lifting. Although this phenomenon can effectively alleviate local pressure concentration, it will also lead to insufficient contact pressure on the top of the convex surface of the hub cover plate, making it impossible to effectively grind this area and affecting the wire drawing effect. Because the clamping band 330 adopts a transitional arc structure with a central convexity and gradually decreasing ends, and in combination with the convex structure of the clamping band 330 and the operator's pressing pressure on the equipment, the lifting of the first wave structure 311 and the second wave structure 321 will cause the central convexity of the clamping band 330 to deform slightly towards the support wheel 210. At this time, the central convexity of the clamping band 330 will apply pressure to the first wave structure 311 and the second wave structure 321 in the direction of the convex surface of the hub cover plate, so that the first wave structure 311 and the second wave structure 321 maintain effective contact with the top of the convex surface of the hub cover plate, thereby maintaining the effective contact between the first sanding belt 310 and the second sanding belt 320 and the surface of the hub cover plate. This not only relieves pressure concentration, but also ensures the uniformity and consistency of the wire drawing effect of the first sanding belt 310 and the second sanding belt 320 on the surface of the hub cover plate.

[0061] During the wire drawing process on the concave surface of the wheel hub cover, when the first abrasive belt 310 and the second abrasive belt 320 contact the concave surface of the wheel hub cover, the concave surface of the wheel hub cover has an inward concave structure, which can easily lead to poor adhesion with the first abrasive belt 310 and the second abrasive belt 320, affecting the wire drawing effect. At this time, the transition arc structure of the clamping belt 330 forms a complementary fit with the concave surface of the wheel hub cover. Simultaneously, during operation, the operator's pressure on the equipment causes the clamping belt 330 to move closer to the first sanding belt 310 and the second sanding belt 320. This causes the middle of the clamping belt 330 to apply pressure to the first wave structure 311 and the second wave structure 321 in the direction of the concave surface of the wheel hub cover. This ensures that the first sanding belt 310 and the second sanding belt 320 are in close contact with the concave surface of the wheel hub cover, thereby maintaining effective contact between the first sanding belt 310 and the second sanding belt 320 and the surface of the wheel hub cover. This guarantees the uniformity and consistency of the wire drawing effect of the first sanding belt 310 and the second sanding belt 320 on the surface of the wheel hub cover.

[0062] Specifically, when the first sanding belt 310 and the second sanding belt 320 perform wire drawing on the flat surface of the wheel hub cover, since the flat surface does not exert opposing forces on the first wave structure 311 and the second wave structure 321, the overall tension of the first sanding belt 310 and the second sanding belt 320 remains consistent. Therefore, the pressing belt 330 does not apply excessive pressure to the first wave structure 311 and the second wave structure 321, ensuring the uniformity and consistency of the wire drawing effect of the first sanding belt 310 and the second sanding belt 320 on the surface of the wheel hub cover.

[0063] In one embodiment, the first sanding belt 310 and the second sanding belt 320 have different grit counts. Specifically, if the operator holds the angle grinder 100 and slides the first sanding belt 310 and the second sanding belt 320 from left to right on the surface of the hub cover plate, that is... Figure 1 In the left-right direction, the mesh size of the first sanding belt 310 is set to be smaller than that of the second sanding belt 320; if the operator holds the angle grinder 100 and drives the first sanding belt 310 and the second sanding belt 320 to slide from right to left on the surface of the hub cover plate, that is... Figure 1 In the left-right direction, the mesh size of the second sanding belt 320 is set to be smaller than that of the first sanding belt 310. Therefore, it is ensured that when brushing the surface of the wheel hub cover, coarse grinding can be performed first, followed by fine grinding, while avoiding the problem of frequently changing the mesh size of sandpaper or sanding belt, effectively improving the brushing efficiency.

[0064] Specifically, the first abrasive belt 310 and the second abrasive belt 320 use abrasive belts with different mesh sizes. The first wave structure 311 and the second wave structure 321 are arranged alternately to form a transition area between the first abrasive belt 310 and the second abrasive belt 320. This ensures that the two abrasive belts 310 and 320 with different mesh sizes are not completely independent in space during the wire drawing process, but rather form a certain degree of superposition and gradation in the transition area, thereby achieving a smooth transition between abrasive belts of different mesh sizes on the wheel hub cover surface. Therefore, it effectively avoids undesirable phenomena such as surface texture jumps, uneven wire drawing, or obvious scratches caused by abrupt changes in mesh size, and plays a good buffering and transition role.

[0065] In one embodiment, the hub cover wire drawing device further includes an adjustment mechanism and a tensioning mechanism. The adjustment mechanism is used to adjust the unfolding angle of the first support 201 and the second support 202, and the tensioning mechanism is used to maintain the tension of the pressing belt 330, the first sanding belt 310 and the second sanding belt 320.

[0066] In one embodiment, the adjustment mechanism includes a toggle lever 416, an adjusting lever 414, and a first spring 411. The adjusting lever 414 is disposed near the hinge between the first bracket 201 and the second bracket 202, and is slidably disposed inside the first bracket 201, with one end of the adjusting lever 414 abutting against the second bracket 202. A sliding groove is formed on the first bracket 201, and the toggle lever 416 passes through the sliding groove and is vertically fixedly connected to the adjusting lever 414. The toggle lever 416 can slide within the sliding groove, causing the adjusting lever 414 to slide relative to the first bracket 201.

[0067] In one embodiment, the adjusting mechanism further includes a first spring 411 and a fixing nut 417. One end of the first spring 411 is fixedly connected to the first bracket 201, and the other end is fixedly connected to the second bracket 202. The fixing nut 417 is coaxially rotatably connected to the actuating lever 416, and the fixing nut 417 is used to fix the actuating lever 416. The elastic force of the first spring 411 cooperates with the adjusting action of the fixing nut 417 to maintain the opening angle of the first bracket 201 and the second bracket 202.

[0068] Specifically, the hubcap has multiple spoke gaps, and the shape and size of each spoke gap often vary to some extent, thus affecting the brushing effect on the hubcap surface. When the spoke gap is small, the operator first pushes the second bracket 202 to slide to the right, i.e. Figure 9 The left and right directions are adjusted to allow relative rotation between the first bracket 201 and the second bracket 202. Then, manually rotating the fixing nut 417 releases the restriction on the actuating lever 416, and sliding the actuating lever 416 downwards moves the adjusting lever 414 to the preset position. Figure 9The adjusting rod 414 is rotated vertically and the fixing nut 417 is rotated in the opposite direction to fix the actuating rod 416. At this time, the overlapping area between the adjusting rod 414 and the first bracket 201 is reduced, and then the pushing force on the second bracket 202 is released. The elastic force of the first spring 411 drives the second bracket 202 to rotate in the opposite direction until it abuts the adjusting rod 414, reducing the opening angle between the first bracket 201 and the second bracket 202, so that the overall structural size is reduced accordingly to accommodate the smaller spoke gap. When the spoke gap is large, the position of the actuating rod 416 is adjusted in the opposite direction to increase the overlapping area between the adjusting rod 414 and the first bracket 201, so that the opening angle between the first bracket 201 and the second bracket 202 is increased, thereby expanding the overall structural size to accommodate the larger spoke gap.

[0069] Therefore, by adjusting the position of the lever 416, the length of the adjusting lever 414 extending into the first bracket 201 can be changed, thereby changing the overlap area between the adjusting lever 414 and the second bracket 202, thus realizing the adjustment of the opening angle of the first bracket 201 and the second bracket 202.

[0070] Throughout the adjustment process, the elastic force of the first spring 411 continuously drives the second bracket 202 to reset, and together with the locking of the toggle lever 416 by the fixing nut 417, they maintain a stable opening angle between the first bracket 201 and the second bracket 202. At the same time, the tensioning mechanism continuously maintains the tension of the pressure belt 330, the first sanding belt 310, and the second sanding belt 320.

[0071] In one embodiment, the tensioning mechanism includes a fixed plate 415, a first tensioning block 401, a second tensioning block 402, and a tensioning wheel 410. The fixed plate 415 is fixedly connected to the first bracket 201, and the first tensioning block 401 is fixedly connected to the fixed plate 415. The second tensioning block 402 is slidably connected to the first tensioning block 401, and the tensioning wheel 410 is fixedly connected to the second tensioning block 402. The tensioning wheel 410 is coaxially rotatably connected to a set of support wheels 210.

[0072] In one embodiment, the tensioning mechanism further includes a second spring 412 and a third spring 413. The second spring 412 is disposed inside the first tensioning block 401, with one end fixedly connected to the first tensioning block 401 and the other end fixedly connected to the second tensioning block 402. The elastic force of the second spring 412 always tends to cause the second tensioning block 402 to move away from the first tensioning block 401. The third spring 413 is disposed outside the second tensioning block 402, with one end fixedly connected to the second tensioning block 402 and the other end fixedly connected to the first tensioning block 401. The elastic force of the third spring 413 is used to limit the second tensioning block 402 from disengaging from the first tensioning block 401.

[0073] Specifically, when the opening angle between the first support 201 and the second support 202 decreases, the elastic force of the second spring 412 pushes the second tension block 402 to slide upward and slide relative to the first tension block 401, that is... Figure 8 The vertical direction of the tensioning wheel 410 and the support wheel 210 connected to the tensioning wheel 410 slide upward synchronously, thereby adjusting and maintaining the tension of the pressure belt 330, the first sand belt 310 and the second sand belt 320.

[0074] When the opening angle between the first support 201 and the second support 202 increases, the clamping belt 330, the first sanding belt 310, and the second sanding belt 320, under tension, will push the second tensioning block 402 downward, thereby compressing the second spring 412. During this process, the second spring 412 applies an upward elastic force to the second tensioning block 402, i.e. Figure 8 In the vertical direction, the direction of the elastic force is opposite to the direction of the thrust of the pressure belt 330, the first sand belt 310 and the second sand belt 320 on the second tension block 402, forming a dynamic balance, thereby maintaining the tension state of the pressure belt 330, the first sand belt 310 and the second sand belt 320.

[0075] In particular, the wheel hub covers equipped with different vehicle models vary in size. To improve the versatility and adaptability of this equipment, the overall structure is designed to be expandable. Operators can adjust the overall structure of the equipment proportionally to the actual size requirements of the wheel hub covers, adapting to corresponding size changes simultaneously to achieve efficient production of products of different specifications.

[0076] The following are the working steps of the wheel hub cover wire drawing equipment:

[0077] S100. Check the integrity of the installation of each component;

[0078] S110. Select a wheel hub cover wire drawing device that matches the size of the wheel hub cover.

[0079] S120. Inspect and install the first sanding belt 310, the second sanding belt 320 and the clamping belt 330, ensuring that the first sanding belt 310 and the second sanding belt 320 are correctly fitted on the first placement position 211 of the support wheel 210 and the clamping belt 330 is correctly fitted on the second placement position 212 of the support wheel 210.

[0080] S130. Adjust the unfolding angle of the first support 201 and the second support 202 according to the size of the spoke gap by using the fixing nut 417, adjusting rod 414 and toggle rod 416.

[0081] S200, start the angle grinder 100, which drives the first sanding belt 310, the second sanding belt 320 and the pressure belt 330 to move synchronously.

[0083] S220, The operator moves the handheld angle grinder 100 in one direction to make the first sanding belt 310 and the second sanding belt 320 perform a wire drawing process on the surface of the hub cover plate;

[0084] S300. During the wire drawing process, when the first abrasive belt 310 and the second abrasive belt 320 pass over the convex surface of the wheel hub cover, the first wave structure 311 and the second wave structure 321 undergo adaptive deformation to reduce local pressure; the clamping belt 330 ensures that the first wave structure 311 and the second wave structure 321 maintain effective contact with the top of the convex surface of the wheel hub cover, thereby maintaining effective contact between the first abrasive belt 310 and the second abrasive belt 321 and the surface of the wheel hub cover; when the first abrasive belt 310 and the second abrasive belt 320 pass over the concave surface of the wheel hub cover, the clamping belt 330 makes the first abrasive belt 310 and the second abrasive belt 320 fit tightly against the concave surface of the wheel hub cover;

[0085] S310. After completing one stroke, lift the equipment, return to the starting point, and repeat the next unidirectional wire drawing.

[0086] S400, turn off angle grinder 100, and check the wire drawing effect;

[0087] S410. If it is necessary to change the mesh size of the first sanding belt 310 or the second sanding belt 320, or to adjust the equipment, repeat stages S120 to S400.

[0088] S500, Finally, check whether the texture of the wheel hub cover surface meets the preset quality standard.

[0089] The present invention also includes a wire drawing process for a wheel hub cover wire drawing device, which is applied to the wheel hub cover wire drawing device in any of the above embodiments.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
