Embodiment Construction
[0020] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0021] refer to Figure 4 , a seamless cylindrical metal working plate, including a working plate main body 31, the working plate main body 31 is a cylindrical metal working plate, and the outer peripheral surface of the working plate main body 31 has a holographic pattern 32 of required laser information. The above-mentioned working plate main body 31 can be a cylindrical structure with the same diameter at both ends; however, it is preferred that the working plate main body 31 is a micro-conical structure, and the difference between the diameters of the two ends is 0.2-2.0 mm. The working plate main body 31 is formed by nickel electroforming. The seamless cylindrical metal working plate 3 of the present invention can meet the hardness requirements of all current molding production. The working plate 3 has a seamless cylindrical structure, and the produ...

The invention relates to a manufacturing process of a seamless cylindrical metal working plate. The manufacturing process successively includes the following steps: manufacturing a metal flat plate with a desired laser holographic pattern; butt-jointing two opposite edges of the flat plate to from a mother plate of a cylindrical structure, and filling and leveling up a butt-jointing gap with UV conductive resin, wherein the holographic pattern is positioned on an inner surface of the cylindrical mother plate; sealing and insulating an outer surface of the cylindrical mother plate, energizing the inner surface of the cylindrical mother plate to perform electroforming; and finally, removing an electroforming deposited metal layer from the cylindrical mother plate to acquire the cylindrical working plate. The seamless cylindrical metal working plate can meet various hardness demands of mould pressing production at present, the produced products have not any plate gap, a laser positioning mold pressing function of various products can be achieved; and the seamless cylindrical metal working plate is long the service life, can reused, can effectively reduce the cost of mold pressing production, and improves the efficiency of mold pressing production.
Description
technical field [0001] The invention relates to a preparation process of a laser molded work plate, in particular to a seamless cylindrical metal work plate and its production process. Background technique [0002] Most of the current laser patterns are formed by molding with a molding machine. Most of the existing molding presses use the planar plate (nickel plate) with holographic laser information to be fixed on the circumferential surface of the steel roll to form a cylindrical plate roll for continuous holographic molding production. If there is only one seam, the products produced will have seams. In order to eliminate the plate gap, there are currently two ways to achieve it: first, the secondary molding process, the product needs to be molded twice, and the plate gap produced by the first molding is eliminated through the second molding process; the secondary molding process is for The production effect of high-precision laser products is not ideal, and the current...
