Description

Technical Field

[0001] The present invention relates to the technical field of new material tensile testing, and specifically relates to a fabric tensile testing device for UD cloth. Background Art

[0002] The new material UD cloth uses new high-performance fiber materials, such as new aramid fibers and high-performance carbon fibers. These fibers have unique molecular structures and excellent properties, which can endow the UD cloth with ultra-high strength, high modulus, resistance to extreme environments, etc. They are significantly different from traditional materials. When applied in the fields of aerospace and high-end military equipment, their unique properties can meet emerging needs and open up new application scenarios. As a kind of new material, after the production of the new material UD cloth, it is necessary to use a tensile testing device to perform tensile testing on it to test its performance. Before the tensile testing, it is necessary to prepare samples of the new material UD cloth first.

[0003] However, when the existing fabric tensile testing device for UD cloth is in use, wrinkles are likely to occur on the samples of the new material UD cloth, which is not convenient for leveling the samples of the new material UD cloth, thus not convenient for detecting the fiber direction, and further not convenient for ensuring that the direction of the tensile force is consistent with the fiber direction, thereby affecting the detection efficiency and the accuracy of the results. Moreover, when preparing samples of the new material UD cloth, flying filaments are likely to be generated. When clamping and fixing, the flying filaments are likely to overlap with the samples of the new material UD cloth, which will make the fiber distribution uneven in some parts of the samples and also affect the accuracy of the detection results.

[0004] Therefore, we propose a fabric tensile testing device for UD cloth. Summary of the Invention

[0005] The purpose of the present invention is to provide a fabric tensile testing device for UD cloth to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A fabric tensile testing device for UD cloth, including a housing and a protective door, and further including:

[0007] Two groups of symmetrically arranged detection mechanisms, which are arranged in the housing and are used for tensile testing of UD cloth samples;

[0008] Each group of the detection mechanisms includes:

[0009] A moving mechanism, which is arranged at the bottom of the housing, and two symmetrically arranged first moving blocks are connected to the moving mechanism. The moving mechanism is used for moving the first moving blocks;

[0010] A lifting mechanism, which is arranged on the opposite side walls of the two first moving blocks, and two L-shaped scraping plates are connected to the lifting mechanism. The lifting mechanism is used for lifting the scraping plates;

[0011] A rotating mechanism is arranged on each of the scraping plates, and a rotating plate is connected to the rotating mechanism. The rotating mechanism is used to rotate the rotating plate.

[0012] A moving component is arranged on the side wall of each of the rotating plates, and a clamping plate is connected to the moving component. The moving component is used to move the clamping plate.

[0013] A vision sensor is fixed on the side wall of each of the clamping plates and is used to detect the fiber direction of the UD cloth sample.

[0014] A blowing mechanism is arranged on each of the scraping plates and is used to blow the UD cloth sample.

[0015] Preferably, the rotating mechanism includes an L-shaped plate fixedly connected to the scraping plate, and a motor is fixedly connected to the top of the L-shaped plate. The output end of the motor is fixedly connected to a rotating disk, and a lifting component is arranged between the rotating disk and the rotating plate.

[0016] By adopting the above technical solution, when the motor is started, the rotation of the motor drives the rotation of the rotating disk. At the same time, the rotating plate is driven to rotate through the rotating mechanism and the lifting component, and then the clamping plate is driven to rotate through the moving component, so that the clamping plate is perpendicular to the fiber direction of the UD cloth sample.

[0017] Preferably, the lifting component includes two symmetrically arranged first sleeves fixedly connected to the bottom of the rotating disk. Each first sleeve is inserted with a first sleeve rod. The lower end of the first sleeve rod is fixedly connected with a connecting disk, and a first spring is sleeved on the side wall of each first sleeve. The bottom of the connecting disk is fixedly connected with a connecting rod, and the lower end of the connecting rod is fixed to the top of the rotating plate. A first electromagnet is fixedly connected to the bottom of the rotating disk, and a first iron block is fixedly connected to the top of the connecting disk.

[0018] By adopting the above technical solution, when the first electromagnet is powered off, after the first electromagnet is powered off, the connecting disk can move downward under the action of the first spring. At the same time, it can drive the clamping plate to move towards the UD cloth sample, and the clamping plates on the two groups of detection mechanisms clamp and fix the UD cloth sample.

[0019] Preferably, the moving component includes a second moving block, and a first moving module is arranged between the second moving block and the rotating plate. A distance sensor is fixedly inserted into the side wall of the second moving block, and two symmetrically arranged second sleeves are fixedly connected to the side wall of the second moving block. Each second sleeve is inserted with a second sleeve rod, and the other end of the second sleeve rod is fixedly connected with a third moving block. A connecting block is fixedly connected between the third moving block and the clamping plate, and a second spring is sleeved on the side wall of each second sleeve.

[0020] By adopting the above technical solution, when tensile testing is required, the first moving module drives the two clamping plates to move away from each other. At this time, the UD cloth specimen can be stretched. Meanwhile, the second spring is gradually stretched. By detecting the distance of the third moving block through the distance sensor, the deformation amount of the second spring can be determined, and then the tensile force on the UD cloth specimen can be determined.

[0021] Preferably, the blowing mechanism includes a hollow cover fixedly connected to the scraping plate, and the side wall of the hollow cover is provided with an inclined air outlet, and a gas supply mechanism is arranged on the side wall of the hollow cover.

[0022] By adopting the above technical solution, during leveling, the gas supply mechanism supplies gas into the hollow cover and blows it out through the air outlet, blowing on the upper and lower surfaces of the new material UD cloth specimen, so that the flying filaments can be straightened, avoiding the multiple overlapping of the flying filaments with the UD cloth specimen, and ensuring the accuracy of subsequent test results.

[0023] Preferably, the gas supply mechanism includes two symmetrically arranged U-shaped hoses fixedly connected to the side wall of the hollow cover. A first hose is fixedly connected between the two U-shaped hoses, and a second hose is fixedly connected to the side wall of the first hose.

[0024] By adopting the above technical solution, an external blower supplies gas to the second hose, so that the air enters the hollow cover through the second hose and the first hose.

[0025] Preferably, the moving mechanism includes a U-shaped plate fixedly connected to the bottom of the housing, and two symmetrically arranged fixing plates are fixedly connected to the top of the U-shaped plate. Two symmetrically arranged T-shaped guide rods are fixedly connected to the side walls of the respective first moving blocks, and the T-shaped guide rods are inserted into the side walls of the fixing plates. A third spring is sleeved on the side walls of the respective T-shaped guide rods, and the movement of the first moving blocks is pushed by a pushing mechanism.

[0026] By adopting the above technical solution, the pushing mechanism can push the two groups of first moving blocks to move away from each other. Meanwhile, the third spring is compressed.

[0027] Preferably, the pushing mechanism includes a mounting plate fixedly connected to the side wall of each scraping plate, and a pushing rod is fixedly connected to the mounting plate. The inner side wall of the housing is connected to a moving plate through a second moving module, and a plurality of L-shaped blocks are fixedly connected to the side wall of the moving plate. An inclined plate is fixedly connected to each L-shaped block, and the pushing rod can slide on the inclined plate.

[0028] By adopting the above technical solution, the second moving module drives the moving plate to move away from the housing. At the same time, the L-shaped block drives the inclined plate to move. When the inclined plate abuts against the side wall of the push rod, it can push the two groups of push rods to move away from each other, and drive the two scraping plates to move away from each other through the mounting plate.

[0029] Preferably, the lifting mechanism includes second electromagnets fixedly connected to each first moving block. A second iron block is fixedly connected to the scraping plate, and a reset mechanism is arranged between the scraping plate and the first moving block.

[0030] By adopting the above technical solution, the second electromagnet is powered off. At this time, the two scraping plates on each group of detection mechanisms can move closer to each other under the action of the reset mechanism and abut against the upper and lower surfaces of the UD cloth sample.

[0031] Preferably, the reset mechanism includes two symmetrically arranged third sleeves fixedly connected to the first moving block. A third sleeve rod is inserted into each third sleeve, and the other end of the third sleeve rod is fixed to the scraping plate. A fourth spring is sleeved on the side wall of each third sleeve.

[0032] By adopting the above technical solution, it can play a role in guiding and resetting the movement of the scraping plate.

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] Embodiment 1

[0052] Please refer to Figures 1 - 12 , a fabric stretching detection device for UD fabric in the illustration, the overall structure

[0053] The device mainly consists of a housing 101, a protective door 102, and two sets of detection mechanisms symmetrically arranged inside the housing 101. The detection mechanism is used to perform stretching detection on UD fabric samples. When performing stretching detection on the new material UD fabric, it is convenient to level the UD fabric specimen and facilitate detecting the fiber direction of the UD fabric specimen. At the same time, it is convenient to blow and straighten the flying filaments on the surface of the UD fabric specimen to avoid multiple overlaps of the flying filaments with the UD fabric specimen. Moreover, it is convenient to ensure that the stretching force is consistent with the fiber direction of the UD fabric specimen, thereby ensuring the efficiency of subsequent detection and the accuracy of the results.

[0054] Each part of the detection mechanism

[0055] Moving mechanism

[0056] Structural features: It includes a U-shaped plate 11 fixed to the bottom of the housing 101, and there are two symmetric fixing plates 601 on the top of the U-shaped plate 11. There are two symmetric T-shaped guide rods 602 on the side wall of the first moving block 1201. The T-shaped guide rods 602 are inserted into the side wall of the fixing plate 601, and a third spring 603 is sleeved on the side wall.

[0057] Connection relationship: The first moving block 1201 is connected to the fixing plate 601 through the T-shaped guide rod 602. The movement of the first moving block 1201 is pushed by a pushing mechanism. Through the pushing mechanism, two sets of first moving blocks 1201 can be pushed to move away from each other. At the same time, the third spring 603 is compressed.

[0058] Lifting mechanism

[0059] Structural features: There is a second electromagnet 701 on the first moving block 1201, and a second iron block 702 on the scraping plate 1202. There is also a reset mechanism, including two symmetric third sleeves 802 on the first moving block 1201. A third sleeve rod 801 is inserted into the third sleeve 802, and a fourth spring 803 is sleeved on the side wall of the third sleeve 802, which can play a guiding and resetting role in the movement of the scraping plate 1202. The elastic coefficient of the fourth spring 803 is smaller than that of the first spring 303, ensuring the scraping effect of the hollow cover 1203 on the new material UD cloth sample and the clamping effect of the clamping plate 1209 on the new material UD cloth sample.

[0060] Connection relationship: The scraping plate 1202 is connected to the third sleeve 802 on the first moving block 1201 through the third sleeve rod 801. The second electromagnet 701 and the second iron block 702 cooperate to control the lifting of the scraping plate 1202. When the second electromagnet 701 is powered off, at this time, the two scraping plates 1202 on each group of detection mechanisms can move closer to each other under the action of the reset mechanism and abut against the upper and lower surfaces of the UD cloth sample.

[0061] Rotating mechanism

[0062] Structural features: There is an L-shaped plate 201 on the scraping plate 1202. There is a motor 202 at the top of the L-shaped plate 201. The output end of the motor 202 is connected to a rotating disk 1205. There is a lifting component between the rotating disk 1205 and the rotating plate 1206. The lifting component includes two symmetric first sleeves 301 at the bottom of the rotating disk 1205. A first sleeve rod 302 is inserted into the first sleeve 301. The lower end of the first sleeve rod 302 is connected to a connecting disk 306. A first spring 303 is sleeved on the side wall of the first sleeve 301. There is a connecting rod 307 at the bottom of the connecting disk 306 connecting the rotating plate 1206. There is a first electromagnet 304 at the bottom of the rotating disk 1205, and a first iron block 305 at the top of the connecting disk 306.

[0063] Connection relationship: The motor 202 drives the rotating disk 1205 to rotate. The rotating disk 1205 is connected to the rotating plate 1206 through the lifting component. The lifting and rotation of the rotating plate 1206 are realized through the first electromagnet 304, the first iron block 305 and the first spring 303. When the motor 202 is started, the rotation of the motor 202 drives the rotation of the rotating disk 1205. At the same time, the rotating plate 1206 is driven to rotate through the rotating mechanism and the lifting component, and then the clamping plate 1209 is driven to rotate through the moving component, so that the clamping plate 1209 is perpendicular to the fiber direction of the UD cloth sample.

[0064] Moving component

[0065] Structural features: On the side wall of the rotating plate 1206, there is a first moving module 401 connected to a second moving block 402. On the side wall of the second moving block 402, there is a distance sensor 406 and two symmetric second sleeves 403. Inserted into the second sleeve 403 is a second rod 404. The other end of the second rod 404 is connected to a third moving block 1207. The third moving block 1207 and the clamping plate 1209 are connected by a connecting block 1208. Sleeved on the side wall of the second sleeve 403 is a second spring 405.

[0066] Connection relationship: The first moving module 401 drives the second moving block 402 to move. The second moving block 402 is connected to the third moving block 1207 through the second sleeve 403, the second rod 404, and the second spring 405. The third moving block 1207 is connected to the clamping plate 1209 through the connecting block 1208. When tensile testing is required, the first moving module 401 drives the two groups of clamping plates 1209 to move away from each other. At this time, the UD cloth specimen can be stretched. At the same time, the second spring 405 is gradually stretched. By detecting the distance of the third moving block 1207 through the distance sensor 406, the deformation amount of the second spring 405 can be determined, and thus the tensile force on the UD cloth specimen can be determined.

[0067] Blowing mechanism

[0068] Structural features: On the scraping plate 1202, there is a hollow cover 1203. On the side wall of the hollow cover 1203, there is an inclined air outlet 1204, and there is a gas supply mechanism on the side wall. The gas supply mechanism includes two symmetric U-shaped hoses 901 on the side wall of the hollow cover 1203. There is a first hose 902 between the U-shaped hoses 901. On the side wall of the first hose 902, there is a second hose 10, and the second hose 10 is connected to the outlet of an external blower.

[0069] Connection relationship: The U-shaped hoses 901, the first hose 902, and the second hose 10 of the gas supply mechanism are connected to the hollow cover 1203 to supply gas to the hollow cover 1203. During leveling, gas is supplied into the hollow cover 1203 through the gas supply mechanism and blown out through the air outlet 1204, blowing on the upper and lower surfaces of the new material UD cloth specimen, so that the flying filaments can be straightened, avoiding the multiple overlaps of the flying filaments with the UD cloth specimen, and ensuring the accuracy of subsequent test results.

[0070] Other components

[0071] Vision sensor 1210: Fixed on the side wall of the clamping plate 1209, used to detect the fiber direction of the UD cloth sample.

[0072] Pushing mechanism: There is a push rod 502 on the mounting plate 501 on the side wall of the scraping plate 1202. The inner side wall of the housing 101 is connected to the moving plate 505 through the second moving module 503. The first moving module 401 and the second moving module 503 are well-known technologies in this technical field and will not be elaborated here. There are multiple L-shaped blocks 506 on the side wall of the moving plate 505, and there is an inclined plate 504 on the L-shaped block 506. The push rod 502 can slide on the inclined plate 504. The pushing mechanism drives the moving plate 505 to move through the second moving module 503, and then the inclined plate 504 pushes the push rod 502 to drive the scraping plate 1202 to move. By driving the moving plate 505 to move away from the housing 101 through the second moving module 503, at the same time, the inclined plate 504 is driven to move through the L-shaped block 506. When the inclined plate 504 abuts against the side wall of the push rod 502, it can push the two groups of push rods 502 to move away from each other, and drive the two groups of scraping plates 1202 to move away from each other through the mounting plate 501.

[0073] Working principle: During use, place the prepared UD cloth sample between the two scraping plates 1202. Then, cut off the power supply of the second electromagnet 701. At this time, the two scraping plates 1202 on each detection mechanism can move closer to each other under the action of the fourth spring 803 and abut against the upper and lower surfaces of the UD cloth sample. Then, drive the moving plate 505 to move away from the housing 101 through the second moving module 503. At the same time, drive the inclined plate 504 to move through the L-shaped block 506. When the inclined plate 504 abuts against the side wall of the push rod 502, it can push the two groups of push rods 502 to move away from each other, and drive the two groups of scraping plates 1202 and the hollow cover 1203 to move away from each other through the mounting plate 501. At the same time, the third spring 603 is compressed. At this time, the UD cloth sample can be leveled through the hollow cover 1203. A rubber pad can be provided on the side wall of the hollow cover 1203 close to the UD cloth sample. At the same time, supply air to the second hose 10 through an external blower, so that the air enters the hollow cover 1203 through the second hose 10 and the first hose 902 and is blown on the upper and lower surfaces of the UD cloth sample through the air outlet 1204, so that the flying filaments can be straightened, avoiding the multiple overlaps of the flying filaments with the UD cloth sample and ensuring the accuracy of the subsequent detection results.

[0074] After the leveling is completed, the fiber direction of the UD cloth sample is detected by observing it with the vision sensor 1210 to determine the fiber direction of the UD cloth sample. Then, the motor 202 is started, and the rotation of the motor 202 drives the rotation of the rotating disk 1205. At the same time, the rotating plate 1206 is driven to rotate through the rotating mechanism and the lifting assembly, and then the clamping plate 1209 is driven to rotate through the moving assembly, so that the clamping plate 1209 is perpendicular to the fiber direction of the UD cloth sample. Then, the first electromagnet 304 is powered off. After the first electromagnet 304 is powered off, the connecting disk 306 can move downward under the action of the first spring 303, and at the same time, it can drive the clamping plate 1209 to move towards the UD cloth sample, and the clamping plates 1209 on the two groups of detection mechanisms clamp and fix the UD cloth sample. When tensile testing is required, the two clamping plates 1209 are driven to move away from each other by the first moving module 401. At this time, the UD cloth sample can be stretched, and at the same time, the second spring 405 is gradually stretched. By detecting the distance of the third moving block 1207 with the distance sensor 406, the deformation amount of the second spring 405 can be determined, and then the tensile force on the UD cloth sample can be determined. During the detection, it can be ensured that the tensile force is consistent with the fiber direction of the UD cloth sample, thus ensuring the accuracy of the detection results.

[0075] After the detection is completed, the first electromagnet 304 is powered on. After the first electromagnet 304 is powered on, it attracts the first iron block 305. At the same time, the first spring 303 is compressed. At this time, the clamping plate 1209 quickly separates from the UD cloth sample. After the clamping plate 1209 separates from the UD cloth sample, the second moving block 402 is driven to move and reset by the first moving module 401, and at the same time, the clamping plate 1209 can move and reset under the action of the second spring 405.
