Description of the Invention: [Technology Leading Technology of the Invention] The present invention relates to a method for processing a mold, in particular to a method for processing a positioning and replacing stamping die. [Prior Art] A common stamping die (10, see The first figure shows an upper mold (11) and a lower mold (12). The upper mold (11) is stamped with respect to the lower mold (12) by reciprocation and displacement, and the upper mold (11) is formed on one side by a plurality of moldings. a punch (111) 'the lower mold (12) is formed with a plurality of punches (121) relative to the punch (丨丨丨) of the upper mold (11), and the workpiece is placed in the lower mold 2, When the upper mold (11) is displaced relative to the lower mold (12), once the punch (in) and the punch (121) are not opposite each other, the punch (in) is damaged (121). ), the workpiece is also smashed at the same time. At this time, the punching (121) must be repaired before it can be used. 'The stamping die (1〇) is very expensive to repair, not only to re-drill the stamping die (10) Heat treatment, wire cutting and grinding, repeated damage repair will also be a heavy burden. SUMMARY OF THE INVENTION The present invention is a method for processing a positioning and replacement stamping die, the purpose of which is to improve the accuracy of stamping and to provide repeatability of stamping materials. In order to achieve the above object, the present invention locates a replacement stamping die processing method, comprising: 201114517 A. Preparing a positioning step: preparing a positioning replacement mold having an upper mold and a mold opposite to the upper mold, the upper mold is subjected to The power source is driven to be displaceably disposed on the lower mold side, the upper mold molding at least a punching column, and the lower mold is shaped at least with respect to the punching column, and the punching pole of the upper mold is opposite to the punching hole of the lower mold Positioning, when the punching column is punched into the punching hole, the outer wall of the punching column and the inner wall of the punching hole will form an offset gap; and B. the second step of punching: the surface of the lower die is attached Laminating the sheet, the punching end of the lower mold is covered by the contact sheet, and the upper mold is driven by the power source to be displaced toward the lower mold, so that the punching portion of the upper mold stamps and forms at least one positioning hole for the bonding sheet For secondary positioning. The outer diameter of the punch of the upper mold is smaller than the outer diameter of the punch of the lower mold. The inner diameter of the positioning hole of the bonding piece is equal to the outer diameter of the punching column of the upper mold. Through the above further analysis, the following effects can be obtained: 1. The present invention provides a quick change of the user through the bonding sheet to speed up the processing, and utilizes the precise positioning of the bonding sheet to improve the efficiency of the coffee machine, and avoids the destruction of the processed product. rate. 2. The present invention utilizes the outer diameter of the punch of the upper mold to be smaller than the outer diameter of the punch of the lower mold to allow the displacement gap between the punch and the punch to be offset by the offset gap, thereby reducing the chance of collision with each other. Maintenance costs. The present invention has been described with reference to the embodiments and the detailed description of the present invention, and the objects, features and other advantages of the present invention are believed to be Specific understanding. [Embodiment] Please refer to the second to eighth figures of the embodiment of the present invention: The positioning and replacement stamping die processing method of the present invention comprises (see the second figure): A. Preparing a positioning step (refer to the second, 3 and 4): preparing a positioning replacement mold (20) having an upper mold (21) and a lower mold (22) opposite to the upper mold (21), the upper mold (21) being movable The lower mold (22) is of a fixed type, and the upper mold (21) is driven to be displaceably disposed opposite to the lower mold (22) by a power source, and the upper mold (21) is formed by at least one punch (211). The lower mold (22) forms at least one punch (221) with respect to the punch (211) 'the punch (.211) of the upper mold (21) and the punch (221) of the lower mold (22) The cross-sectional area of the punch (211) of the upper mold (21) is smaller than the cross-sectional area of the punch (221) of the lower mold (22) when the punch (211) punches into the punch (221). When the outer wall of the punching column (211) and the inner wall of the punching hole (221) will form an offset gap (A), the punching column (211) will not impact the punching hole (221). B. Stamping secondary positioning step (refer to Figures 5 and 6): the surface (222) of the lower mold (22) is pasted with a fit (23) to punch the lower mold (22) ( 221) The end is covered by the bonding piece (23), and the upper die (21) is driven by the power source 201114517 to be displaced toward the lower die (22), so that the punching (211) of the upper die (21) is attached to the die The splicing piece (23) is stamped and formed into at least one positioning hole (231) for secondary positioning, and the secondary positioning is more precise than the one positioning, because the punching column (211) of the upper mold (21) directly directly aligns the aligning piece (23) stamping, so that the internal control of the positioning hole (231) of the bonding piece (23) coincides with the outer diameter of the punching column (211), and the positioning hole (231) of the bonding piece (23) is located On the displacement path of the punching column (2Π), the workpiece (B, see FIG. 7) is placed on the bonding piece (23), because of the bonding piece (23) The positioning hole (231) and the punching rod (211) of the upper mold (21) are accurately positioned, so that the punching rod (211) of the upper mold (21, see FIG. 8) can accurately process the workpiece (B). Punching at the desired position, the fit piece 23) can provide users depending on the needs replacing, without taking the entire lower mold (22) removed for damage repair.
