Description

Technical Field

[0001] The present application relates to the technical field of product surface wire drawing treatment, and in particular to a wire drawing wheel die repairing tool. Background Art

[0002] Surface brushing is a surface treatment method that forms lines on the surface of the product by grinding it to achieve a decorative effect. Surface brushing generally uses a wire drawing wheel, which is driven by a driving device to rotate the wire drawing wheel and press the workpiece to be drawn against the sand surface of the wire drawing wheel. As the grinding progresses, the sand surface of the wire drawing wheel will present multiple irregular surfaces, which is prone to uneven drawing, wire breakage and other undesirable conditions.

[0003] In order to reduce the possibility of product defects, the wire drawing wheel is usually repaired by rotating the diamond grinding wheel at high speed. After the repair, there are slight bulges on the surface of the wire drawing wheel, resulting in an uneven wheel surface. At the same time, due to insufficient internal adhesion of the wire drawing wheel, cracks and bulges appear due to the squeezing pressure of the diamond grinding wheel. In addition, during the repair process, the grinding fluid is difficult to completely rinse the wire drawing wheel, resulting in residual hair chips, and the filtration system is overwhelmed, which in turn affects the product quality.

[0045] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0048] like Figure 1-Figure 7 As shown, the embodiment of the present application provides a wire drawing wheel die repairing tool 1, which can be applied to a wire drawing machine. Specifically, the wire drawing wheel die repairing tool 1 is 1:1 contoured according to the workpiece to be processed, and the wire drawing wheel die repairing tool 1 can replace the workpiece to be processed and be installed on the machine table 2 of the wire drawing machine, and perform trimming on the wire drawing wheel 3 installed on the wire drawing machine.

[0049] Specifically, refer to Figure 4-Figure 7The workpiece to be processed is installed on the machine table 2 of the wire drawing machine. When the wire drawing program is started, the wire drawing wheel 3 moves along the surface of the workpiece to be processed according to a predetermined trajectory, so that the surface of the workpiece to be processed is subjected to wire drawing. The wire drawing wheel die repairing tool 1 is installed on the machine table 2 of the wire drawing machine. When the wire drawing program is started, the wire drawing wheel 3 moves along the surface of the wire drawing wheel die repairing tool 1 according to a predetermined trajectory, so that the wire drawing wheel die repairing tool 1 performs a surface finishing process on the wire drawing wheel 3.

[0050] like Figure 6-Figure 9 As shown, the wire drawing wheel die repairing tool 1 includes a profiling body 10 and a plurality of die repairing structures 12. The outer contour of the profiling body 10 is 1:1 profiling with the appearance of the workpiece to be processed, so that the profiling body 10 can replace the workpiece to be processed and be installed on the machine table 2 of the wire drawing machine. The profiling body 10 includes two end faces 102 and a side surface 100 located between the two end faces. When the wire drawing program is started, the wire drawing wheel 3 can move along the side surface 100 of the profiling body 10 according to a predetermined trajectory. A plurality of die-repairing structures 12 are arranged on the side surface 100 of the profiling body 10, and each die-repairing structure 12 is distributed at intervals along the side surface 100 of the profiling body 10. When the wire drawing wheel 3 moves along the side surface 100 of the profiling body 10 along a predetermined trajectory, each die-repairing structure 12 interacts with the wire drawing wheel 3 in turn, thereby continuously trimming the surface of the wire drawing wheel 3. In other words, the surface of the wire drawing wheel 3 can be trimmed by only starting the wire drawing program, and there is no need to set up a separate die-repairing device, thereby simplifying the trimming operation of the wire drawing wheel 3 and improving the trimming efficiency of the wire drawing wheel 3. Moreover, the die-repairing operation path of the wire drawing wheel 3 is the same as the wire drawing operation path, and there is no need to set up a separate die-repairing operation path, thereby ensuring the stability of the wire drawing machine operation as much as possible and improving the trimming effect of the wire drawing wheel 3.

[0051] Furthermore, the material of the profiling body 10 is high-hardness alloy steel, which ensures that the profiling body 10 has high hardness while reducing production costs; the side surface 100 of the profiling body 10 is provided with a diamond coating, which improves the hardness of the side surface 100 of the profiling body 10, reduces the surface wear of the die repair tool, and ensures the repair effect. In a specific embodiment, the diamond coating can be formed on the side surface 100 of the profiling body 10 by electroplating diamond abrasives, the abrasive particle size is 60#, and the average particle size is 250μm. It can be understood that the profiling body 10 can also use other methods to improve the surface hardness, such as heat treatment hardening, or the profiling body 10 can also be directly made of diamond.

[0052] Furthermore, the die trimming structure 12 includes a forward scraping portion 120 and a reverse trimming portion 122 that are relatively arranged, and the forward scraping portion 120 is sharper than the reverse trimming portion 122; the forward scraping portion 120 is used to remove burrs on the surface of the drawing wheel 3 and crush lumps inside the drawing wheel 3 so that the drawing wheel 3 forms a regular surface; the reverse trimming portion 122 is used to remove slight protrusions on the surface of the drawing wheel 3 and improve the flatness of the surface of the drawing wheel 3; under the joint action of the forward scraping portion 120 and the reverse trimming portion 122, a reliable trimming effect of the surface of the drawing wheel 3 is achieved, and the drawing wheel 3 trimmed by the drawing wheel die trimming tool 1 has a first-time yield of 89.66% in the wire drawing process, and a wire drawing defective rate is reduced by about 4.2%.

[0053] Specifically, the wire drawing wheel die repairing tool 1 provided in the embodiment of the present application can perform a trimming process on the wire drawing wheel 3 in the following manner: Step S1, the wire drawing wheel die repairing tool 1 is mounted and fixed on the machine table 2 (for example, mounted on a U-axis rotating structure); Step S2, the wire drawing program is started, and the wire drawing wheel 3 moves forward along a predetermined trajectory (for example, Figure 6 The wire drawing wheel 3 rotates forward and grinds the outer surface of the profiling jig according to the processing path, feeds in batches, and the cutting depth is 0.2mm-0.5mm. The wire drawing wheel 3 moves against the forward scraping portion 120, so that the profiling body 10 can cut and scrape the surface of the wire drawing wheel 3; step S3, reverse according to the predetermined trajectory (for example, Figure 7 The wire drawing wheel 3 moves toward the reverse trimming portion 122 , so that the wire drawing wheel 3 can be slightly trimmed by the profiling body 10 .

[0054] Among them, the forward scraping portion 120 can be integrally formed with the profiling body 10, or it can be connected to the profiling body 10 by welding or fasteners, and the edge of the forward scraping portion 120 forms a cutting edge; similarly, the reverse trimming portion 122 can be integrally formed with the profiling body 10, or it can be connected to the profiling body 10 by welding or fasteners, and the edge of the reverse scraping portion forms a cutting edge; the cutting edge of the forward scraping portion 120 is in the opposite direction to the cutting edge of the reverse scraping portion.

[0055] like Figure 8-Figure 10 As shown, the positive scraping portion 120 is arranged to be an acute-angle structure at least at the edge, that is, the angle of the cutting edge of the positive scraping portion 120 is 0° to 90°, so as to improve the sharpness of the positive scraping portion 120 and the mold repairing efficiency, thereby quickly forming a regular surface on the surface of the drawing wheel 3.

[0056] Further, the angle α of the acute angle structure is 25° to 30°, that is, the angle of the cutting edge of the positive scraper 120 is 25° to 30°. For example, the angle α of the acute angle structure can be 25°, 25.5°, 26°, 26.5°, 27°, 27.5°, 28°, 28.5°, 29°, 29.5° or 30°, etc., so as to efficiently remove the burrs on the surface of the drawing wheel 3 and crush the agglomerates inside the drawing wheel 3. When the acute angle structure is less than 25°, the strength of the positive scraper 120 is insufficient, and it is difficult to effectively crush the agglomerates inside the drawing wheel 3, and it is also easy to cause damage such as wear or chipping; when the acute angle structure is greater than 30°, the sharpness of the positive scraper 120 is reduced, and it is difficult to effectively remove the burrs on the surface of the drawing wheel 3, thereby affecting the dressing efficiency and dressing effect of the drawing wheel 3.

[0057] Furthermore, the reverse trimming portion 122 is arranged to be a right-angle structure at least at the edge, that is, the cutting edge angle of the reverse trimming portion 122 is 90°, so that the reverse trimming portion 122 is processed perpendicular to the surface of the drawing wheel 3, thereby reducing vibration and deformation during the trimming process, ensuring the stability of the processing quality, and then forming a clear and flat trimming surface, thereby improving the trimming effect of the drawing wheel 3.

[0058] Furthermore, a scraper groove 124 is formed between the forward scraping portion 120 and the reverse trimming portion 122. The scraper groove 124 is recessed in the side surface 100 of the contoured body 10 and passes through the two end surfaces 102 of the contoured body 10. During the trimming of the drawing wheel 3, the scraper groove 124 is used to clean and accommodate the hair scraps generated during the trimming of the drawing wheel 3, and at the same time, it helps to break up the rubber clumps inside the drawing wheel 3, thereby improving the cleaning effect of the surface of the drawing wheel 3 and reducing the workload of the filtering system.

[0059] Specifically, the scraper groove 124 includes a first wall surface 1240, a second wall surface 1242 and a bottom surface 1244. The first wall surface 1240 extends inward from the surface of the profiling body 10, the second wall surface 1242 extends inward from the surface of the profiling body 10, the first wall surface 1240 and the second wall surface 1242 are arranged at intervals, the bottom surface 1244 is located between the first wall surface 1240 and the second wall surface 1242, and the bottom surface 1244 connects the first wall surface 1240 and the second wall surface 1242, so as to form a scraper groove 124 with a certain depth on the surface of the profiling body 10. Among them, transition structures such as fillets can be set between the first wall surface 1240 and the bottom surface 1244, and between the second wall surface 1242 and the bottom surface 1244, so as to reduce stress concentration and improve the reliability of the wire drawing wheel die repairing tool 1.

[0060] Furthermore, the first wall 1240 and the surface of the contoured body 10 form a forward scraper portion 120, and an acute angle structure is formed between the first wall 1240 and the side surface 100 of the contoured body 10, which can not only make the forward scraper portion 120 and the contoured body 10 integrally formed to avoid the forward scraper portion 120 from loosening or falling off, thereby improving the reliability of the wire drawing wheel die repairing tool 1 itself, but also ensure that the hair scraps cut off by the forward scraper portion 120 smoothly enter the scraper groove 124.

[0061] Furthermore, the second wall surface 1242 and the surface of the profiling body 10 form a reverse trimming portion 122, and a right-angle structure is formed between the second wall surface 1242 and the side surface 100 of the profiling body 10, which can not only make the reverse trimming portion 122 and the profiling body 10 integrally formed to avoid the reverse trimming portion 122 from loosening or falling off, thereby improving the reliability of the wire drawing wheel die repairing tool 1 itself, but also ensure that the hair scraps cut off by the reverse trimming portion 122 can smoothly enter the scraper groove 124.

[0062] Furthermore, the depth H of the scraper groove 124 is 0.5mm~1.5mm, that is, the distance between the bottom surface 1244 of the scraper groove 124 and the side surface 100 of the contoured body 10 is 0.5mm~1.5mm. For example, the depth H of the scraper groove 124 can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm or 1.5mm, etc., which can effectively clean the residual hair on the surface of the drawing wheel 3 and ensure the dressing effect of the drawing wheel 3. When the depth H of the scraper groove 124 is less than 0.5 mm, it is difficult for the scraper groove 124 to fully clean and accommodate the hair debris, resulting in a large amount of residual hair debris on the surface of the drawing wheel 3; when the depth H of the scraper groove 124 is greater than 1.5 mm, the strength of the forward scraper portion 120 and the reverse trimming portion 122 is weakened, resulting in the forward scraper portion 120 and the reverse trimming portion 122 being prone to damage such as vibration or breakage, thereby affecting the trimming effect of the drawing wheel 3.

[0063] Furthermore, the slot width W1 of the scraper groove 124 is 1 mm to 1.5 mm, for example, the slot width W1 of the scraper groove 124 can be 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm, etc., to form a reliable hair cleaning effect. When the slot width W1 of the scraper groove 124 is less than 1 mm, the scraper groove 124 is easily blocked; when the slot width W1 of the scraper groove 124 is greater than 1.5 mm, it is difficult to fully break up the glue mass in the drawing wheel 3.

[0064] Further, the groove bottom width W2 of the scraper groove 124 is 1.5 mm to 2.5 mm, for example, the groove bottom width W2 of the scraper groove 124 can be 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm or 2.5 mm, etc., so as to fully utilize the space of the scraper groove 124 to accommodate hair scraps. When the groove bottom width W2 of the scraper groove 124 is less than 1.5 mm, it is difficult to effectively accommodate hair scraps; when the groove bottom width W2 of the scraper groove 124 is greater than 2.5 mm, the edge of the scraper groove 124 forms a dead corner where hair scraps are difficult to reach.

[0065] Further, the plurality of scraper grooves 124 are evenly spaced, and the average distance L between each two adjacent scraper grooves 124 is 11 mm to 12 mm. For example, the average distance L between adjacent scraper grooves 124 is 11 mm, 11.1 mm, 11.2 mm, 11.3 mm, 11.4 mm, 11.5 mm, 11.6 mm, 11.7 mm, 11.8 mm, 11.9 mm or 12 mm, so that there are about two scraper grooves 124 in the contact surface of the drawing wheel 3, thereby improving the dressing effect of the drawing wheel 3. When the average distance L between adjacent scraper grooves 124 is less than 11 mm, the interval between adjacent scraper grooves 124 is too small, resulting in insufficient strength of the trimming structure 12, affecting the dressing effect of the drawing wheel 3; when the average distance L between adjacent scraper grooves 124 is greater than 12 mm, the number of scraper grooves 124 in the contact surface of the drawing wheel 3 is too small, resulting in the difficulty in meeting the dressing effect of the drawing wheel 3.

[0066] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
