Abstract
Description
Technical Field
[0001] The utility model relates to the field of detection of composite materials, in particular to a peeling 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, forming a material with new properties macroscopically or microscopically. Each material makes up for each other's weaknesses in performance, generates a synergistic effect, and makes the comprehensive performance of the composite material superior to that of the raw materials to meet 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 prior art 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 peeling surface. However, the randomness of this treatment method is relatively large, and the peeling effect varies from person to person, and it cannot 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] Therefore, the inventor designed a set of solutions. The solution is to first cut a cut a (as Figure 4 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 5 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 6 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 peeling angle, the inventor specifically designed a peeling device for detecting the composite strength of composite materials. Utility Model Content

[0029] This embodiment provides a stripping device 1 for detecting the composite strength of a composite material. Among them, the composite material includes at least two materials with different properties, the composite material is strip-shaped, and the width of the composite material is less than or equal to 12.5 mm.
[0030] See Figures 1 to 3, the stripping device 1 includes a stripping base body 11. The stripping base body 11 has a receiving groove 111 for receiving the composite material. A first stripping portion 12 is provided below the receiving groove 111, and a second stripping portion 13 is provided above the receiving groove 111. The second stripping portion 13 corresponds to the first stripping portion 12, and the second stripping portion 13 is directly above the first stripping portion 12. The punched composite material is placed into the receiving groove 111. At this time, the cut a of the composite material faces upward, and the back of the cut a faces the first stripping portion 12. Then, the composite material is pulled downwards, and the first stripping portion 12 abuts against the back of the composite material. The first stripping portion 12 initially spreads open the cut a, so that the composite material forms a first angle b at the cut a (as Figure 5 shown). Then, the composite material is flipped and placed back into the receiving groove 111. At this time, the cut a of the composite material faces downward, and the back of the cut a faces the second stripping portion 13. Finally, the composite material is pulled upwards, and the second stripping portion 13 abuts against the back of the composite material. The second stripping portion 13 spreads open the cut a again, so that the composite material forms a second angle c at the cut a. The first angle b is greater than the second angle c. At this time, the cut a includes a complete cross-section of at least one layer of material (as Figure 6 shown).
[0031] Specifically, the receiving groove 111 is provided on the top surface of the stripping base body 11. The receiving groove 111 opens upward. The receiving groove 111 extends horizontally from one side surface of the stripping base body 11 to the other side surface of the stripping base body 11. The end of the receiving groove 111 is open on the side surface of the stripping base body 11 to form an entrance for the composite material to enter and exit.
[0032] Specifically, the first stripping portion 12 is provided at the bottom edge of the entrance of the receiving groove 111. The first stripping portion 12 is arc-shaped. By designing the first stripping portion 12 to be arc-shaped, the stress concentration during the pulling process of the composite material can be reduced, and the complete fracture of the composite material can be avoided. In this embodiment, the arc angle of the first stripping portion 12 is 90 degrees. Moreover, the radius of the first stripping portion 12 is smaller than the radius of the second stripping portion 13. In this embodiment, the radius of the second stripping portion 13 is twice the radius of the first stripping portion 12.
[0033] Specifically, the stripping device 1 further includes a stripping angle upper limit block 14. The stripping angle upper limit block 14 is provided on the top surface of the stripping base body 11. The stripping angle upper limit block 14 covers a part of the opening of the receiving groove 111. The second stripping portion 13 is provided on the side of the stripping angle upper limit block 14 close to the entrance of the receiving groove 111. The second stripping portion 13 is arc-shaped, and the arc angle of the first stripping portion 12 is smaller than the arc angle of the second stripping portion 13. By designing the second stripping portion 13 to be arc-shaped, the stress concentration during the pulling process of the composite material can be reduced, and the complete fracture of the composite material can be avoided. In this embodiment, the arc angle of the second stripping portion 13 is 180 degrees.
[0034] To avoid directly breaking the composite material, the first angle b should be greater than 90 degrees and less than 180 degrees. Therefore, the peeling device 1 further includes a lower limit block 15 for the peeling angle. The lower limit block 15 for the peeling angle is arranged on the side surface of the peeling base 11. The lower limit block 15 for the peeling angle and the first peeling portion 12 are located on the same side of the peeling base 11, and the lower limit block 15 for the peeling angle is located below the first peeling portion 12. When the first angle b is formed at the incision a of the composite material, the composite material abuts against the lower limit block 15 for the peeling angle, ensuring that the first angle b is greater than 90 degrees and less than 180 degrees. Moreover, the lower limit block 15 for the peeling angle can limit the turning amplitude of the composite material, ensuring that each operation is at the same angle and the same peeling angle. To meet different requirements, the peeling base 11 is bolted to the lower limit block 15 for the peeling angle. The side surface of the peeling base 11 is provided with a first connection hole 112, and the lower limit block 15 for the peeling angle is provided with a first sliding groove 151. After the bolt passes through the first sliding groove 151, it is threadedly connected to the first connection hole 112, and the bolt slides within the first sliding groove 151. According to the required angle, the position of the lower limit block 15 for the peeling angle can be adjusted up and down.
[0035] In addition, the peeling device 1 further includes a peeling limit block 16, and the peeling limit block 16 is located in the moving track of the composite material within the receiving groove 111. The peeling limit block 16 is placed in front of the moving composite material. After the composite material extends into the receiving groove 111, until the end of the composite material abuts against the peeling limit block 16, the forward movement of the composite material stops. At this time, the back of the incision a directly corresponds to the first peeling portion 12 or the second peeling portion 13. Specifically, the upper limit block 14 for the peeling angle has a peeling limit through hole 141, and the peeling limit block 16 moves back and forth within the peeling limit through hole 141. The upper limit block 14 for the peeling angle is bolted to the peeling limit block 16. The top surface of the upper limit block 14 for the peeling angle is provided with a second connection hole 142, and the peeling limit block 16 is provided with a second sliding groove 161. After the bolt passes through the second sliding groove 161, it is threadedly connected to the second connection hole 142, and the bolt slides within the second sliding groove 161. In this way, the position of the peeling limit block 16 within the receiving groove 111 can be adjusted to adapt to different composite materials.
[0036] Working process of the peeling device 1: First, insert the cut composite material into the receiving groove 111 until the end of the composite material touches the peeling limit block 16, and then the incision a is located above the first peeling part 12; then, pull down the composite material until it abuts against the peeling angle lower limit block 15. During this process, the first peeling part 12 abuts against the back of the composite material, and the first peeling part 12 initially expands the incision a; next, turn over the composite material and insert it into the receiving groove 111 again until the end of the composite material touches the peeling limit block 16, and then the incision a is located below the second peeling part 13; subsequently, pull up the composite material until it abuts against the top surface of the peeling angle upper limit block 14. During this process, the second peeling part 13 abuts against the back of the composite material, and the second peeling part 13 expands the incision a again; finally, the incision a includes the entire cross-section of at least one layer of material, and the lamination condition of the composite material is observed through the incision a.
[0037] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on 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 belong to the protection scope of the present utility model.
