Description

Technical Field

[0001] This utility model relates to the field of light-shielding sheet processing technology, specifically a self-made high-precision stamping die. Background Technology

[0002] Light-blocking sheets are mainly used in the fields of optics and imaging. They are thin, sheet-like components used to control, block, or shape light. Their core function is to prevent unwanted stray light, ensuring that light only passes through a predetermined path, thereby improving the quality of the image, measurement accuracy, and display effect. For specific structure details, please refer to [reference needed]. Figure 1 The light-shielding sheet 10 has a ring-shaped overall structure, mainly consisting of a light-shielding sheet body 101 and a light-transmitting hole 102 formed in the middle of the light-shielding sheet body 101. The traditional processing method involves manually cutting the light-shielding sheet blank from the carrier belt, and then using a special jig and stamping cutter to punch the light-transmitting hole 101 into the light-shielding sheet blank to obtain the finished light-shielding sheet 10. This processing method is cumbersome, inefficient, and cannot be formed in one step, increasing manufacturing costs. To address this, the inventor designed a self-made high-precision stamping die. Utility Model Content

[0003] The purpose of this invention is to provide a self-made high-precision stamping die, which has the advantages of simple structure, reasonable design, one-time forming of light-shielding sheets, low processing cost and high efficiency, thus solving the problems mentioned in the above technical background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-made high-precision stamping die, which includes a base and an upper die seat disposed above the base. The upper and lower end faces of the upper die seat are respectively provided with an upper fixed column and a lower fixed column, wherein the lower fixed column is fixedly connected to the base, so that a gap is formed between the base and the upper die seat for the movement of the light-shielding pad material. The upper fixed column is fixedly connected to a cylinder fixing seat, and a cylinder is fixedly installed on the cylinder fixing seat. The output end of the cylinder is connected to a stamping knife. The stamping knife passes through the cylinder fixing seat and the upper die seat from top to bottom and extends to the outside of the upper die seat. Under the action of the cylinder, the stamping knife cooperates with the positioning groove on the base to stamp and form the light-shielding pad material to obtain a light-shielding sheet.

[0005] Preferably, there are two upper fixing columns and two lower fixing columns, and the two upper fixing columns and two lower fixing columns are symmetrically distributed along the central axis of the upper mold base.

[0006] Preferably, both the upper die holder and the cylinder fixing seat are provided with a through hole for the stamping knife to pass through, and the outer diameter of the through hole is larger than the outer diameter of the stamping knife.

[0007] Preferably, the stamping knife has a cylindrical structure and consists of an inner pressing knife and an outer pressing knife. The outer pressing knife is sleeved on the outside of the inner pressing knife. A conical outer cutting head is provided on the outer pressing knife. A circular external through hole is opened on the outer cutting head, and an external cutting edge is formed around the external through hole. An inner cutting head is provided on the inner pressing knife. An internal through hole is opened on the inner cutting head, and an internal cutting edge is formed along the circumference of the internal through hole. The inner cutting edge and the outer cutting edge cooperate to stamp the light-shielding sheet pad material into a light-shielding sheet product.

[0008] Preferably, the inner pressure knife and the outer pressure knife are arranged coaxially.

[0009] Preferably, the internal through holes are distributed along the length direction of the internal pressure knife.

[0010] Preferably, the height of the inner cutting edge is greater than the height of the outer cutting edge.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a self-made high-precision stamping die, which includes a base and an upper die seat disposed above the base. An upper fixing post and a lower fixing post are respectively disposed on the upper and lower end faces of the upper die seat. The lower fixing post is fixedly connected to the base, forming a gap between the base and the upper die seat for the movement of the light-shielding pad material. The upper fixing post is fixedly connected to a cylinder fixing seat, on which a cylinder is fixedly mounted. The output end of the cylinder is connected to a stamping cutter. Under the action of the cylinder, the stamping cutter cooperates with the positioning groove on the base to stamp and form the light-shielding pad material. With a simple structure and reasonable design, the stamping knife in this utility model consists of an inner pressure knife and an outer pressure knife. The inner pressure knife is provided with an inner cutting edge, and the outer pressure knife is provided with an outer cutting edge. The height of the inner cutting edge is greater than that of the outer cutting edge. When the cylinder drives the stamping knife to stamp and form the light-shielding sheet material on the base, the outer cutting edge first contacts the light-shielding sheet material and stamps out the light-shielding sheet blank. Then, the cylinder continues to drive the stamping knife to press down, and the inner cutting edge contacts the light-shielding sheet blank to form the finished light-shielding sheet. The entire process can form the light-shielding sheet in one go, with low processing cost and high efficiency, and is worthy of widespread promotion and application. Attached Figure Description

[0017] Please see Figures 1 to 3 This utility model provides an embodiment of a self-made high-precision stamping die, which includes a base 1 and an upper die seat 2 disposed above the base 1. The upper and lower end faces of the upper die seat 2 are respectively provided with upper fixing posts 21 and lower fixing posts 22. Two upper fixing posts 21 and two lower fixing posts 22 are provided, symmetrically distributed along the central axis of the upper die seat 2. The lower fixing posts 22 are fixedly connected to the base 1, forming a gap 4 between the base 1 and the upper die seat 2 for the movement of a light-shielding pad material 3. In actual operation, the light-shielding pad material 3 is pulled by a traction mechanism (not shown in the figure). The light-shielding material 3 is slowly passed through the gap 4. The upper fixed column 21 is fixedly connected to the cylinder fixed seat 5. The cylinder fixed seat 5 is fixedly installed with a cylinder 6. The output end of the cylinder 6 is connected to a stamping knife 7. In order to facilitate the replacement of the stamping knife 7, the stamping knife 7 is detachably installed at the output end of the cylinder 6. More specifically, the stamping knife 7 is connected to the output end of the cylinder 6 by threads or detachable screws. The stamping knife 7 passes through the cylinder fixed seat 5 and the upper mold seat 2 from top to bottom and extends to the outside of the upper mold seat 2. Under the action of the cylinder 6, the stamping knife 7 cooperates with the positioning groove 11 on the base 1 to stamp and form the light-shielding pad material 3 to obtain the light-shielding sheet 10.

[0018] Specifically, both the upper mold base 2 and the cylinder fixing base 5 are provided with a stamping knife through hole 8 for the stamping knife 7 to pass through, and the outer diameter of the stamping knife through hole 8 is larger than the outer diameter of the stamping knife 7.

[0019] Please see Figures 4 to 6 The stamping knife 7 in the figure has a cylindrical structure and is composed of an inner pressing knife 71 and an outer pressing knife 72. The outer pressing knife 72 is sleeved on the outside of the inner pressing knife 71. A conical outer cutting head 73 is provided on the outer pressing knife 72. A circular external through hole 74 is opened on the outer cutting head 73, and an external cutting edge 75 is formed around the external through hole 74. An inner cutting head 76 is provided on the inner pressing knife 71. An internal through hole 77 is opened on the inner cutting head 76, and an internal cutting edge 78 is formed on the inner cutting head 76 along the circumference of the internal through hole 77. The inner cutting edge 78 and the outer cutting edge 75 cooperate to stamp the light-shielding pad material 3 into a light-shielding product.

[0020] Specifically, the inner pressure knife 71 and the outer pressure knife 72 are coaxially arranged.

[0021] Specifically, the inner through holes 77 are distributed along the length direction of the inner pressure knife 71.

[0022] Specifically, the height of the inner cutting edge 78 is greater than the height of the outer cutting edge 75.

[0023] Please refer to it again. Figures 1 to 6When the stamping die of this utility model is working, the cylinder 6 drives the stamping knife 7 to stamp the light-shielding pad material 3 on the base 1. Since the height of the inner knife edge 78 is greater than the height of the outer knife edge 75, the outer knife edge 75 of the stamping knife 7 contacts the light-shielding pad material 3 first and stamps out the light-shielding blank. Then the cylinder 6 continues to drive the stamping knife 7 to press down, and the inner knife edge 78 contacts the light-shielding blank again to form the finished light-shielding sheet 10. The whole process can form the light-shielding sheet 10 in one go. The processing cost is low and the efficiency is high, which is worth promoting and applying.
