Description

Technical Field

[0001] This utility model relates to the field of fabric impact technology, specifically to an impact resistance testing device for aramid fiber composite fabrics. Background Technology

[0002] In the field of materials science, aramid fiber composite fabrics are widely used in aerospace, safety protection, and automotive manufacturing industries due to their excellent properties such as high strength, abrasion resistance, and corrosion resistance. However, with the continuous expansion and deepening of application areas, the requirements for the impact resistance of aramid fiber composite fabrics are also increasing.

[0003] Traditional testing methods often involve fixing an impact disc to a rotating rod, then moving the impact disc via the rotating rod to impact the fabric, thus testing the impact resistance of aramid fiber composite fabrics.

[0004] Although the above equipment can test the impact of fabrics, the height of the impact plate cannot be adjusted during impact; impact can only be performed at a fixed height. Utility Model Content

[0005] In view of this, the present invention provides an impact resistance testing device for aramid fiber composite fabrics. The angle of the impact block can be adjusted by tightening the second rope.

[0006] To solve the above-mentioned technical problems, this utility model provides an impact resistance testing device for aramid fiber composite fabrics, including a worktable. A fabric fixing component is arranged in the middle of the worktable. The fabric fixing component includes a slide groove on the worktable, in which two fabric placement blocks are slidably arranged. The two fabric placement blocks have notches, and a top contact block is slidably arranged in the notches. A support frame is arranged on the side of the worktable, located at the side of the slide groove. An impact component is arranged on the support frame. The impact component includes a mounting block at the bottom of the support frame, in which a rotating column is rotatably arranged. An impact block is fixed to the rotating column by a rope. First, the tester places the aramid fiber composite fabric to be tested between the fabric placement blocks, and then clamps the fabric by the top contact block. Next, the tester pulls the impact block by a pulling component in the impact component, causing the rotating column to rotate with the pull of the rope. Then, the pulling component in the impact component is released, and the impact block uses its own weight and the rotational energy of the rotating column to impact the fabric at a relatively fast speed. After being subjected to the impact force, the fabric will produce a certain deformation and stress. If the fabric is not strong enough to withstand the impact, it will tear, indicating that its impact resistance is substandard. Conversely, if the fabric can withstand the impact of the impact block and remain intact, then its impact resistance is considered satisfactory.

[0007] The fabric fixing assembly also includes two threaded rods disposed on the sides of the two fabric placement blocks. The two threaded rods pass through the interior of the fabric placement blocks and are fixedly disposed on the side of the top contact block. Two drive buttons are disposed on the side of each of the two fabric placement blocks. The drive buttons are fixedly disposed on one end of the threaded rods. That is, the drive buttons provide driving force to the threaded rods, thereby causing the top contact block to move, which can indirectly fix the fabric to the top.

[0008] The fabric fixing assembly also includes multiple threaded holes on the worktable, which are located on both sides of the slide. The two fabric placement blocks are engaged with the threaded holes by bolts on both sides, thus providing a way to fix the fabric placement blocks in place.

[0009] The impact assembly also includes two fixed blocks mounted on the upper surface of the support frame, with a fixed rod rotatably mounted between the two fixed blocks, and a second rope wound around the fixed rod; that is, the fixed rod facilitates the release and retraction of the second rope.

[0010] The impact assembly also includes an extension strip located on the side of the support frame. The extension strip is fixed to the support frame by welding. A fixing seat is provided on the upper surface of the extension strip. The fixing seat is fixed to the support frame by welding. A guide roller is provided on the fixing seat. The guide roller can rotate on the fixing seat. A groove is provided on the upper surface of the support frame. The groove is located on the side of the fixing seat. The extension end of the second rope is located on the upper surface of the guide roller and passes through the groove; thus, it provides guidance for the second rope.

[0011] An electromagnet is installed at the end of the second rope; that is, when the electromagnet is energized, it generates magnetism, which causes the electromagnet to magnetically attract the impact block.

[0012] A motor is installed on the support frame, and the output shaft of the motor is fixedly connected to the fixed rod; that is, the motor provides the rotation of the fixed rod, thereby facilitating the adjustment of the tension of the second rope.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The fixed rod is rotated by the output shaft of the motor. Due to the weight of the electromagnet itself, the electromagnet causes the second rope to extend and descend. Then, the electromagnet is energized, causing it to become magnetic and adhere tightly to the impact block. The fixed rod is then driven to rotate again by the motor, causing the second rope to pull the electromagnet and the impact block upward. This allows for adjustment of the tilt angle of the impact block, thereby achieving impacts of different forces.

[0015] 2. The fabric placement block can be fixed by inserting the bolts on both sides into the threaded holes, which makes it easy to adjust the fabric placement block and accommodate fabrics of different sizes. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-4As shown: This embodiment provides an impact resistance testing device for aramid fiber composite fabrics, including a workbench 100. A fabric fixing assembly 200 is disposed in the middle of the workbench 100. The fabric fixing assembly 200 includes a slide groove 202 disposed on the workbench 100. Two fabric placement blocks 203 are slidably disposed in the slide groove 202. The two fabric placement blocks 203 can slide within the slide groove 202, thereby accommodating the testing of aramid fiber composite fabrics with a relatively long width. The two fabric placement blocks 203 are provided with notches 207 for placing the aramid fiber composite fabric. A top contact block 206 is slidably disposed within the notch 207 for fixing the aramid fiber composite fabric with a top contact. A support frame 102 is disposed on the side end of the workbench 100. The support frame 102 is located on the side end of the slide groove 202 and is welded to the side. The impact assembly 300 is fixed to the workbench 100 by means of a connector or bolt. The support frame 102 is equipped with an impact assembly 300. The impact assembly 300 includes a mounting block 309 at the bottom of the support frame 102. The mounting block 309 is fixed to the support frame 102 by welding. A rotating column 310 is rotatably installed inside the mounting block 309. An impact block 308 is fixedly installed on the rotating column 310 by a rope 307. The rope 307 is fixedly installed on the impact block 308 and the rotating column 310. At the same time, the rotating column 310 provides support for the rope 307 and the impact block 308. Simultaneously, it pulls the impact block 308, thereby causing the rotating column 310 to rotate. Then, the impact block 308 is released, which can impact the aramid fiber composite fabric. If the aramid fiber composite fabric is torn by the impact block 308, the quality is not up to standard. If the aramid fiber composite fabric withstands the impact of the impact block 308, the quality is up to standard.

[0027] First, the tester places the aramid fiber composite fabric to be tested on the fabric fixing assembly 200 in the center of the workbench 100. The fabric fixing assembly 200 consists of a slide 202 and two fabric placement blocks 203. The fabric placement blocks 203 can slide within the slide 202 to accommodate fabrics of different widths. Then, the tester places the fabric in the notch 207 and secures it tightly using the sliding top contact block 206 to ensure that the fabric does not move during the test. Next, the tester pulls the impact block 308 using the pulling component in the impact assembly 300 to give it potential energy. During this process, the rotating column 310 rotates with the pull of the rope 307, storing energy. Subsequently, the pulling component in the impact assembly 300 is released, and the impact block 308 uses its own weight and the rotational energy of the rotating column 310 to impact the fabric at a relatively high speed. After being subjected to the impact force, the fabric will undergo a certain deformation and stress. If the strength of the fabric is insufficient to withstand this impact force, it will tear, indicating that its impact resistance performance is unqualified. Conversely, if the fabric can withstand the impact of the impact block 308 and remain intact, then its impact resistance is considered acceptable.

[0028] like Figure 2 As shown,

[0029] The fabric fixing assembly 200 also includes two threaded rods 205 disposed on the sides of the two fabric placement blocks 203. The two threaded rods 205 can rotate within the two fabric placement blocks 203. The two threaded rods 205 pass through the interior of the fabric placement blocks 203 and are fixedly disposed on the side of the top contact block 206, so that the threaded rods 205 drive the top contact block 206 to move, so that the top contact block 206 clamps the aramid fiber composite fabric. Two drive buttons 204 are disposed on the side of each of the two fabric placement blocks 203. The drive buttons 204 are fixedly disposed on one end of the threaded rods 205, so that it is convenient for personnel to use the drive buttons 204 to drive the threaded rods 205.

[0030] like Figure 2 As shown,

[0031] The fabric fixing assembly 200 also includes a plurality of threaded holes 201 provided on the worktable 100. The plurality of threaded holes 201 are located on both sides of the slide 202. The two sides of the fabric placement blocks 203 are engaged with the threaded holes 201 by bolts, thereby facilitating the fixing and adjustment of the fabric placement blocks 203.

[0032] like Figure 2 As shown,

[0033] The impact assembly 300 also includes two fixing blocks 306 disposed on the upper surface of the support frame 102. The two fixing blocks 306 are fixed to the support frame 102 by welding, so that the support frame 102 provides support for the two fixing blocks 306. A fixing rod is rotatably disposed between the two fixing blocks 306. The fixing rod can be supported by the two fixing blocks 306. A second rope 304 is wrapped around the fixing rod.

[0034] The impact assembly 300 also includes an extension strip 301 disposed on the side end of the support frame 102. The extension strip 301 is fixed to the support frame 102 by welding. A fixing seat 303 is disposed on the upper surface of the extension strip 301. A guide roller 305 is disposed on the fixing seat 303. The guide roller 305 can rotate within the fixing seat 303. A groove 302 is disposed on the upper surface of the support frame 102. The groove 302 is located at the side end of the fixing seat 303. The extension end of the second rope 304 is located on the upper surface of the guide roller 305 and passes through the groove 302, thereby providing guidance for the second rope 304.

[0035] An electromagnet 101 is provided at the end of the second rope 304. The electromagnet 101 is installed on the second rope 304. The impact block 308 can be attracted by the attraction force of the electromagnet 101.

[0036] A motor 103 is installed on the support frame 102. The output shaft of the motor 103 is fixedly installed with the fixed rod. The motor 103 provides rotation for the fixed rod, so that the rope 2 304 is wrapped around the fixed rod.

[0037] The fixed rod is rotated by the output shaft of the motor 103. Due to the weight of the electromagnet 101, the electromagnet 101 drives the second rope 304 to extend and descend. Then, the personnel energize the electromagnet 101, causing it to become magnetic and adhere tightly to the impact block 308. Then, the fixed rod is driven to rotate again by the motor 103, causing the second rope 304 to pull the electromagnet 101 and the impact block 308 upward, which makes it easier to tilt the impact block 308 at an angle, thereby achieving impacts of different forces.

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
