[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-3 The present invention provides a technical solution: a method for calculating the size of a door panel embossing roller, which specifically comprises the following steps:

[0024] S1: Determine the hardness of the material used to process the door panel;

[0025] S2: Determine the depth and width of the door panel embossing;

[0026] S3: Select the material, length and hardness of the embossing roller according to the material hardness, embossing depth and embossing width of the door panel;

[0027] S4: According to the hardness value x, depth d, width w of the door panel and the length l and hardness y of the embossing roller, take the center of the embossing roller along the length l as the reference, determine n equal points in both directions, and use the existing data values ​​through empirical formula 1: Calculate the maximum radius r(max) of the embossing roller as the radius of the center point of the embossing roller, using the empirical formula 2: r(n) = r(max) ÷ 1.00035 (n-1) Calculate the radius of the embossing roller at the equally divided points on both sides, and connect them smoothly with spline lines to get the generatrix size of the embossing roller;

[0028] S5: Processing the embossing roller through CNC programming;

[0029] S6: Surface engraving and milling processing pattern;

[0030] S7: surface carburizing and quenching treatment;

[0031] Among them, in step S1, the door panel material is mainly low carbon steel, aluminum alloy, copper alloy and stainless steel, and different materials have different hardness x. In step S2, the embossing depth d of the door panel is in the range of 0.3-0.6mm, and the embossing width w of the door panel is in the range of 200-800mm. In step S3, the material of the embossing roller is medium carbon alloy steel or medium carbon steel, and the length l is in the range of 200-1000mm. In step S4, the empirical formula 3 of the several equal points n is: The radius r of the embossing roller extends symmetrically from the center of the length l to both sides and becomes smaller. In step S7, the surface carburizing and quenching treatment ensures that the depth of the hardened layer is not less than 1 mm and the hardness y ranges from HRC55 to HRC60.

[0032] In summary, if Figure 1-3 :Assuming that the door panel material is aluminum alloy, the aluminum alloy hardness x is HRC5, the embossing width w needs to be 600mm, and the embossing depth d needs to be 0.6mm. According to the above door panel material data, the embossing roller length l is selected as 800mm, and the hardness y to be achieved is set to HRC55. At this time, according to the hardness value x of the door panel, the embossing depth d, the embossing width w, the length l and the hardness y of the embossing roller, the above data values ​​are used according to the formula The maximum radius r (max) of the embossing roller is calculated, and r = 88 mm. Then, the center of the embossing roller along the length l is taken as the reference, and n equal points are determined in both directions. The calculation formula of the several points n is: By calculating the formula, we get n≈18. At this time, we take the embossing roller with a length of 800 mm as the reference along the center of the length l, and get 18 equal points in both directions. Then, by the formula r(n)=r(max)÷1.00035 (n-1) Calculate the radius r of 18 equal points along the length l of the embossing roller as the reference, and get the radius r of 18 equal points in both directions, such as Figure 3 , the radius r data values ​​corresponding to 37 points were calculated, and the generatrix size of the embossing roller was obtained by smoothly connecting them with spline lines, and then the following steps were performed:

[0033] S5: Processing the embossing roller through CNC programming;

[0034] S6: Surface engraving and milling processing pattern;

[0035] S7: surface carburizing and quenching treatment;

[0036] The embossing roller processing is completed as above, and the embossing roller processed by the door panel embossing roller size calculation method of the present invention processes patterns on the surface of the door panel. The depth of the pattern of the door panel processed by the embossing roller is more balanced, thereby ensuring the embossing effect and aesthetics of the door panel.
