Description

Technical Field

[0001] The invention relates to paper art technology, and in particular to a combined knife die and a manufacturing method thereof. Background Art

[0002] In order to meet the die-cutting needs of longer paper art, the knife die is designed to be relatively long. At the same time, in order to make up for the defects of the long knife die, a combined knife die design is adopted; The combined knife die manufactured by traditional technology: 1. Each knife die monomer is manufactured as an independent knife die. First, each knife die plate monomer is processed, and then the knife line segments are distributed and etched on each knife die plate monomer. The knife die plate monomer material is hard and difficult to machine. Generally, a forming die is used with the aid of a punch press (thickness 0.8-1.2, no more than 2mm). The processing accuracy is low and the cost is high. Once the size changes, the mold needs to be re-opened; 2. The knife line is first etched on the knife die plate, and then the knife die plate etched with the knife line is divided. The knife die plate material is relatively hard and difficult to cut, and the knife line will inevitably be damaged during the division; The above two methods cannot guarantee the continuity and no missing of the knife line of the combined knife die (process 2 is more serious), especially when process 1 is adopted, it is also particularly time-consuming and labor-intensive, and the processing difficulty is higher. Summary of the invention

[0003] By analyzing the manufacturing process of traditional combined knife dies, we found that: 1) The reason why process 1 "cannot ensure the continuity and integrity of the knife lines of the combined knife dies" is the machining accuracy; 2) The reason why process 2 "cannot ensure the continuity and integrity of the knife lines of the combined knife dies" is that the knife lines are etched out first, at which time the knife lines are continuous and intact, but when the knife plate with etched knife lines is divided, the knife lines will inevitably be damaged, especially the knife lines at the joints.

[0004] Based on the above findings, the present invention proposes a combined cutting die and a manufacturing process thereof, aiming to solve the above problems. The manufactured combined cutting die is accurate, and its cutting lines are continuous and without missing parts.

[0005] The technical solution of the present invention: A method for manufacturing a combined knife die, the method comprising the following steps: 1) Processing several template monomers; 2) Combine the template monomers together to form a whole, namely the knife template; 3) Etch the knife line on the knife plate; That is to complete the manufacture of the combined knife die.

[0006] The above technical solution is further refined. In step 2), each template monomer is combined together by splicing. Step 1) is specific as follows: take a template, which has the same size as the knife template, and divide it into several template monomers, and the dividing seam is the splicing seam; the template monomer processing is simpler.

[0007] Considering the high hardness of the template material, it is preferred to use an etching process during segmentation; the segmentation is more precise, so that the template monomers formed by the separation can be perfectly combined together in a splicing manner.

[0008] The above technical solution is further refined, and each template monomer is connected end to end, and a dovetail groove design is adopted at the connection. With this structure, when each template monomer is combined together by splicing, each template monomer is firmly connected and not easy to loosen, which is beneficial when etching knife lines thereon. Of course, the manufactured combined knife mold is more convenient to use. However, this will undoubtedly bring difficulties to the segmentation of the template (the segmentation line is complicated), and the etching process used during segmentation solves this problem well.

[0009] A combined knife die manufactured by the manufacturing method.

[0010] The advantages of the present invention are reasonable design, ingenious conception, breaking the traditional thinking, etching knife lines on the combined knife plate, the knife lines are etched and formed at one time, and at the same time, the one-time etched knife lines are avoided from being divided, so that the manufactured combined knife die is accurate, and its knife lines are continuous and without missing. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the combined knife die structure.

[0012] In the figure, there are a knife template 1, a template monomer 1-1, a knife line 2, and a dovetail groove 3. DETAILED DESCRIPTION

[0013] In order to further clarify the technical solution of the present application, further description is given below in conjunction with the accompanying drawings.

[0014] As shown in the figure, a combined knife die includes a knife die plate 1 and a knife line 2 etched on the knife die plate 1. The knife die plate 1 is formed into a whole by splicing together a number of template monomers 1-1; when splicing, each template monomer 1-1 is connected end to end, and a dovetail groove 3 is used at the connection; The manufacturing method of the above-mentioned combined mold comprises the following steps: 1) Take a template that is the same size as the knife template, and use the etching process to split it into several template monomers (etch out dovetail grooves), and the split seams are the splicing seams; 2) Connect the template monomers end to end and combine them together by splicing to form a whole, namely the knife template; 3) Etch the knife line on the knife plate; That is to complete the manufacture of the combined knife die.
