[0002] At present, the traditional electroplated aluminum film drawing method has problems such as uneven step skipping and serious waste of electroplated aluminum. In the existing technology, the hot stamping production line frequently replaces the electroplated aluminum, which not only increases material waste, but also significantly reduces production efficiency. In addition, the step design corresponding to different hot stamping pattern forms is cumbersome, and there is a lack of a unified optimization method, which makes it difficult to achieve efficient use of electroplated aluminum.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings: Figure 1 It is the original jump step distance diagram in the prior art; Figure 2 It is the improved skip step diagram of the present invention; DETAILED DESCRIPTION The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0012] In the drawings, the same reference numerals all refer to the same components.

[0013] like Figure 1-2 As shown, the present invention provides a new film drawing method for hot stamping electroplated aluminum: 1. Determine the hot stamping pattern Select multiple irregularly distributed hot stamping patterns, calculate the maximum size of the overall longitudinal jump, and set the anodized aluminum slitting width to 20mm; keep the minimum upper and lower safety distance to 1mm to ensure the integrity of the pattern boundary during the hot stamping process.

[0014] 2. Optimize the step length of skip The vertical dimension of a single hot stamping pattern is measured to be 154mm, and the number of overall sections is calculated. By combining large and small skip steps with uniform step calculation, the skip step is optimized to 97.4mm, which reduces the waste of aluminum foil compared to the traditional 123.2mm skip step design.

[0015] 3. Use the oblique-pull electrochemical aluminum method Adjust the horizontal and vertical film drawing tension of the anodized aluminum to ensure that the pattern arrangement within the wide range of the anodized aluminum is more compact; realize the oblique film drawing of the anodized aluminum, so as to make full use of the space within the 20mm slitting width and increase the number of hot stamping patterns.

[0016] 4. Optimized hot stamping layout Based on the traditional 8-block layout, the block arrangement is optimized to a more efficient way by adjusting the step size. In the specific implementation, the block spacing is adjusted to avoid the waste of anodized aluminum.

[0017] Figure 1 Determine the hot stamping pattern form, multiple irregular distributions. Set the electroplated aluminum slitting width to 20mm, measure a group of hot stamping overall pattern longitudinal jump step maximum size of 62mm, and keep a minimum safety distance of 1mm between the upper and lower positions. The longitudinal size of a single box is 154mm, and a maximum of 4 equal patterns can be placed between two hot stamping patterns. The total number of plates is 8, and the jump step can be 107mm*4 steps + 188mm*1 step. The large and small jump method is converted into a uniform step of 123.2mm. The gaps in the shown patterns are not reasonably utilized, resulting in a waste of aluminum foil. In order to save aluminum foil, we further tried other step jump methods.

[0018] like Figure 2 As shown. Determine the form of the hot stamping pattern, with multiple irregular distributions. Set the electroplated aluminum slitting width to 20mm, measure a set of hot stamping overall pattern longitudinal jump step maximum size of 62mm, and keep a minimum safety distance of 1mm between the upper and lower positions. The longitudinal dimension of a single box is 154mm, and a maximum of 4 equal patterns can be placed between two hot stamping patterns. The total number of plates is 8. We use the oblique electroplated aluminum method on the 20mm electroplated aluminum width. The width of the plate is 6mm, which can be used to put down 2 patterns. The number of plates is 8, so the uniform step is calculated based on the usage of 6 plates. The uniform step can be calculated to be 97.4mm. Compared with the 123.2mm jump step in Figure 1, the utilization rate of electroplated aluminum is improved, and the use of aluminum foil is greatly reduced. Changing the jump step saves about 20% of the cost of the original jump step.

[0019] The present invention significantly improves the utilization rate of anodized aluminum and reduces material waste by about 20% by optimizing the design of anodized aluminum step skipping, combining the calculation of large and small step skipping and uniform step, and adopting the method of obliquely pulling anodized aluminum; at the same time, by reasonably adjusting the layout of the plate and the real-time tension control technology, the stability and consistency of the hot stamping pattern are ensured, the production cost is greatly reduced, and the production efficiency is improved. In addition, the method is applicable to a variety of hot stamping pattern forms and has a wide range of applicability, providing the industry with an efficient, environmentally friendly and economical solution.

[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
