Description

Technical Field

[0001] The utility model relates to the field of detection of composite materials, in particular to a punching device for detecting the composite strength of composite materials. Background Technique

[0002] A composite material is a material composed of two or more materials with different properties, through physical or chemical methods, macroscopically or microscopically forming a material with new properties. Each material makes up for each other's weaknesses in performance, generating a synergistic effect, so that the comprehensive performance of the composite material is superior to the raw materials and meets various different requirements.

[0003] The composite strength of the contact surface of the composite material will be affected by many factors. Therefore, during the production process of the composite material, it is necessary to detect the composite strength of the composite material. At present, the existing technology is to manually twist the composite material up and down randomly to peel the composite material, and observe the composite strength of the composite material through the peeled surface. However, the randomness of this treatment method is relatively large, and the peeling effect varies from person to person, and it is impossible to accurately reflect the composite strength of the composite material. Moreover, the efficiency of this treatment method is also relatively low, and the material waste is also relatively large.

[0004] For this reason, the inventor designed a set of solutions. The solution is to first cut a cut a (as Figure 3 shown) on the composite material. The position of the cut a is unified, and the depth of the cut a is unified; then the composite material is initially pulled, so that the composite material rotates at the cut a, and the pulling angle of the composite material is unified, and the composite material forms a first angle b (as Figure 4 shown); then the composite material is pulled again, so that the composite material rotates at the cut a, and the pulling angle of the composite material is unified, and the composite material forms a second angle c (as Figure 5 shown), and the second angle c is smaller than the first angle b. Through the above solution, the peeling method is unified to ensure that the peeling effect can accurately reflect the actual situation of the material composite.

[0005] In order to unify the cutting position and depth of the cut a, the inventor specifically designed a punching device for detecting the composite strength of composite materials. Utility Model Content

[0027] This embodiment provides a punching device 1 for detecting the composite strength of a composite material. Among them, the composite material includes at least two layers of materials with different properties. The composite material is in a long strip shape, and the width of the composite material is less than or equal to 12.5 mm. Refer to Figure 1 And Figure 2 , the punching device 1 includes a punching base 11 and a cutting knife 12. Among them, the punching base 11 has a receiving groove 1111 for receiving the composite material. The cutting knife 12 is slidably arranged on the punching base 11. The cutting knife 12 cuts out a cut a on the top surface of the composite material. The cut a includes a part of the cross-section of at least one layer of material (as Figure 3 shown).

[0028] Specifically, the punching base 11 includes a punching base 111, a cover plate 112, and a guide seat 113. The top surface of the punching base 111 is provided with a receiving groove 1111 opening upward. The cover plate 112 is arranged on the top surface of the punching base 111, and the cover plate 112 covers the upward-opening of the receiving groove 1111, so that the receiving groove 1111 forms a long groove that is only open at both ends. The guide seat 113 is arranged on the top surface of the cover plate 112. The guide seat 113 is provided with a guide hole 1131 that extends vertically downward and is connected to the receiving groove 1111. The cutting knife 12 slides up and down in the guide hole 1131. The guide seat 113 is used to ensure that the cutting knife 12 does not deviate from the track when cutting downward, and there is no gap between the two, ensuring safety. In addition, the width of the cutting edge of the cutting knife 12 is 0.5 mm, which is more conducive to punching the material on the basis of ensuring the durability of the cutting knife 12.

[0029] To ensure the consistency of the punching length, the punching device 1 further includes a punching limit block 13. The punching limit block 13 is slidably arranged in the punching base body 11, and the punching limit block 13 can extend into the receiving groove 1111. The punching limit block 13 is located on the moving track of the composite material in the receiving groove 1111. Place the punching limit block 13 in front of the movement of the composite material. After the composite material extends into the receiving groove 1111, stop the forward movement of the composite material until the end of the composite material abuts against the punching limit block 13, thereby determining the punching length of the composite material. Specifically, in this embodiment, the cover plate 112 is provided with a punching limit through hole 1121. The punching limit through hole 1121 extends vertically downward and is communicated with the receiving groove 1111; the punching base 111 is provided with a first slot 1115. The first slot 1115 is located in the receiving groove 1111 and corresponds to the punching limit through hole 1121; the punching limit block 13 slides up and down in the punching limit through hole 1121, and the punching limit block 13 is inserted into the first slot 1115 after passing through the punching limit through hole 1121.

[0030] To be applicable to composite materials of different widths, the width of the receiving groove 1111 is greater than the width of the composite material. On this basis, to prevent the composite material from shaking left and right in the receiving groove 1111, the punching device 1 further includes a limit screw 14. The limit screw 14 is threadedly connected to the punching base body 11. The limit screw 14 extends out of the receiving groove 1111, and the end of the limit screw 14 abuts against the composite material to fix the composite material in the receiving groove 1111. By the limit screw 14, it can be ensured that the material does not shake left and right during punching, and the cutting edge a is in the same position every time punching is performed. Specifically, the receiving groove 1111 has a first support surface 1112 for supporting the composite material and first side surfaces 1113 and second side surfaces 1114 respectively located on the left and right sides of the first support surface 1112. The limit screw 14 extends into the receiving groove 1111 from the second side surface 1114, and the limit screw 14 and the first side surface 1113 respectively abut against both side surfaces of the composite material to clamp the composite material.

[0031] The working process of the punching device 1: First, extend the composite material into the receiving groove 1111 until the end of the composite material abuts against the punching limit block 13 to determine the punching length of the composite material; then, the first support surface 1112 abuts against the bottom surface of the composite material, drive the limit screw 14 to rotate, the limit screw 14 extends into the receiving groove 1111 from the second side surface 1114, and the limit screw 14 and the first side surface 1113 jointly clamp the composite material; finally, the cutter 12 cuts a cut a on the top surface of the composite material, and the cut a includes a part of the cross-section of at least one layer of material.

[0032] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
