DETAILED DESCRIPTION

[0035] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0036] Example 1: Reference Figures 1 to 9 A punch process for stretching a patterned paper with sharp edges to twice its original size includes the following steps:

[0037] a. Place the paper to be processed: take 300G pearl paper and place it on the metal female die 200;

[0038] b. Punch processing of the paper to be processed: close the mold of the soft male die 100 and the metal female die 200 to punch the paper to be processed;

[0039] c. Punch processing is completed: open the mold of the soft male die 100 and the metal female die 200, and take out the punched paper.

[0040] The principle and advantages of the above technical solution are:

[0041] Place the paper to be processed on the end face of the metal female die 200, and use the soft male die 100 to close the mold of the paper to be processed. The soft male die 100 punches the surface of the paper to be processed, so that the surface of the paper to be processed forms a punch structure identical to the structure of the soft male die 100. The soft male die 100 is made of elastic material, and the use of the soft male die 100 in combination with the metal female die 200 facilitates the dissipation of stress on the paper to be processed during the punch process, avoiding the extrusion of the metal female die 200 on the paper to be processed during the punch process, which can cause the paper to burst and wrinkle. At the same time, it can be used for punch processing of various papers with different paper qualities. After the punch is completed, the soft male die 100 and the metal female die 200 are opened, and the finished product is taken out. By using the soft male die 100 in combination with the metal female die 200 to punch the paper, a punch effect of a pattern with sharp edges and a paper stretching nearly twice its original size can be achieved.

[0042] Example 2: Reference Figures 1 to 9The metal concave die 200 is provided with a polygonal groove 300, and the polygonal groove 300 is formed by a plurality of U-shaped grooves 400 connected in a head-to-tail mode, and the U-shaped groove 400 is used to achieve a 0.3mm coining height for the paper to be processed.

[0043] The included angle of the U-shaped groove 400 is 62°, and the included angle is used to dissipate the stress generated by the paper to be processed during coining.

[0044] The sharp corner where the two U-shaped grooves 400 intersect is rounded, and the sharp corner is used to block the stress generated by the paper to be processed during coining.

[0045] The soft punch 100 comprises a punch mounting seat 101 and a polygonal resin bottom die 102, and the polygonal resin bottom die 102 is arranged at the bottom end of the punch mounting seat 101, and the polygonal resin bottom die 102 cooperates with the polygonal groove 300 to coining the 300G pearlescent paper.

[0046] The height of the polygonal resin bottom die 102 is 0.6mm, and the polygonal resin bottom die 102 is used to further dissipate the stress generated by the paper to be processed during coining.

[0047] The polygonal groove 300 is provided with a plurality of buffer protrusions 500, and the plurality of buffer protrusions 500 are arranged around the polygonal groove 300.

[0048] The height of the buffer protrusion 500 is 0.4mm, and the width is 4mm, and the buffer protrusion 500 is used to block the bending internal force generated by the paper to be processed during coining from being transmitted to the periphery.

[0049] The two buffer protrusions 500 are conical protrusions at the intersecting included angle.

[0050] The principle and beneficial effects of the above technical scheme are:

[0051] In the process of coining, the polygonal resin bottom die 102 extrudes the upper end face of the paper to be processed, the lower end face of the paper to be processed is extruded into the polygonal groove 300, the polygonal groove 300 shapes the paper to be processed, and the paper to be processed is stressed due to the extrusion of coining, and the stress is dissipated through the cooperation of the polygonal resin bottom die 102 and the polygonal groove 300. Each side of the polygonal groove 300 is a U-shaped groove 400 with a depth of 0.5 mm, which avoids the rupture and tearing of the paper at the edge of the coining due to the stress concentration of the paper to be processed; the intersection angle between the two U-shaped grooves 400 is rounded to avoid the bursting of the paper at the sharp edge of the paper to be processed due to coining; the polygonal groove 300 is provided with a plurality of buffer protrusions 500, and the plurality of buffer protrusions 500 are arranged around the polygonal groove 300. When the paper to be processed is coined, the buffer protrusions 500 block the stress dissipated on the paper, preventing wrinkles from occurring during the coining process; the two buffer protrusions 500 are conical protrusions at the intersection angle, which can reflect the pressure of the polygonal resin bottom die 102 on the paper to the upper side of the coining plane when the paper to be processed is coined, thereby avoiding the transmission of the bending internal force of the triangle to the periphery and improving the appearance of the coining surface of the paper.

When air is extracted, negative pressure is generated between the top end of the conveying assembly 5 and the bottom end of the paper to be processed. The top end of the conveying assembly 5 adsorbs the paper to be processed and then carries it in steps. When the conveying assembly 5 rotates to a position outside the fixed end of the circular track formed thereby, the air guide mechanism 4 is disconnected from the conveying assembly 5. The air guide mechanism 4 slides to the end of the positioning assembly 3. The air guide mechanism 4 extracts air from the top end of the positioning assembly 3 through the air extractor. When air is extracted, negative pressure is generated between the top end of the positioning assembly 3 and the bottom end of the paper to be processed. The positioning assembly 3 positions the paper to be processed. The positive rotation of the conveying assembly 5 carries the paper to be processed from the feeding end of the device to the metal female die 200 on the upper end surface of the mold mounting plate 2, thereby improving the stability of the paper to be processed during the carrying process. The positioning assembly 3 positions the paper to be processed to prevent displacement of the paper to be processed during the coining process, thereby preventing the generation of defective products. After the paper to be processed is fixed on the metal female die 200, the air cylinder is started. The output end of the air cylinder moves downward. The soft male die 100 moves downward.
