Description

Technical Field

[0001] This invention relates to the field of Charpy impact testing technology, and in particular to an automatic impact device and equipment for multi-temperature Charpy testing of metallic materials. Background Technology

[0002] Charpy impact testing is an important method for evaluating the impact toughness of metallic materials under high-energy impact loads. It involves using a pendulum to impact a notched (V- or U-shaped) specimen, and measuring the energy difference to assess the material's toughness. However, existing Charpy pendulum impact tests rely on manual installation and removal of the specimen, which severely limits the overall efficiency and reliability of the results.

[0003] First, operators must place each sample individually in its designated position on the testing machine before starting the test. When multiple samples need to be tested, operators must repeat these steps, resulting in low loading efficiency. Second, manual operation inevitably introduces systematic errors. For example, deviations in sample placement, differences in operation time, and inconsistent operator skill levels can all affect the positioning accuracy of the samples in the testing machine, leading to fluctuations in test results. In particular, when tests involving different temperatures are conducted simultaneously, manual pre-treatment, loading, and unloading exacerbate the accuracy and consistency issues of experimental data due to human error.

[0044] Example 1

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of an automatic impact device for multi-temperature Charpy testing of metallic materials. It includes a sample feeding mechanism 1, a pretreatment mechanism 2, an impact testing machine 3, and a transfer mechanism. The sample feeding mechanism 1 stores the target sample 11 that has not undergone temperature pretreatment (for ease of understanding, the sample without temperature pretreatment is considered the first sample, and the sample with temperature pretreatment is considered the second sample). The pretreatment mechanism 2 performs temperature pretreatment on the target sample 11 according to the test requirements. The target sample 11 is transferred through the transfer mechanism at various stages of the Charpy impact test, including transferring the target sample 11 from the sample feeding mechanism 1 to the corresponding pretreatment mechanism 2 for heat preservation pretreatment, and removing the target sample 11 from the pretreatment mechanism 2 and sending it to the impact testing machine 2 for the Charpy impact test. By setting up the transfer mechanism to replace manual transfer of the target sample 11 between stages of the Charpy impact test, the transfer efficiency and safety are improved. The target sample 11 is a metallic material with external dimensions of 10mm × 10mm × 55mm, and a V-shaped or U-shaped notch is provided on one side of its center.

[0046] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The sample injection mechanism 1 includes a base 17, a first auxiliary mechanism 12, a first propulsion mechanism 13, a first buffer section 14, and a sample storage tank 15. The base 17 includes base feet 171 and a mounting base 172. The first auxiliary mechanism 12, the first propulsion mechanism 13, the first buffer section 14, and the sample storage tank 15 are all mounted on the mounting base 172. The first auxiliary mechanism 12 is adapted to the sample storage tank 15 and mounted on the mounting base 172. The target sample 11 in the sample storage tank 15 is sequentially delivered to the end of the sample storage tank 15 under the action of the first auxiliary mechanism 12. The sample injection end of the sample storage tank 15 is called the front end, and the sample discharge end of the sample storage tank is called the end end. A specific first target area is set at the end. The first propulsion mechanism 13 and the first buffer section 14 are arranged opposite each other on the two outer sidewall areas of the sample storage tank 15. For example, the first propulsion mechanism 13 is set on the outer area of ​​the first sidewall 152, and the first buffer section 14 is set on the second sidewall 153. An external region and a first buffer section 14 are provided in the region adapted to the first propulsion mechanism 13, and the first propulsion mechanism 13 and the first buffer section 14 are adapted to each other. Preferably, the first propulsion mechanism 13 and the first buffer section 14 are provided on the bottom side of the end of the sample storage tank 15. The first propulsion mechanism 13 pushes the target sample 11 in the first target area at the end to the first buffer section 14, so that the transfer mechanism can transfer the target sample 11 on the first buffer section 14 to the next region, such as to the pretreatment mechanism 2 for temperature pretreatment. By setting the first propulsion mechanism 13 and the first buffer section 14, the direct transfer of the target sample 11 from the sample storage tank 15 is changed to the transfer of the target sample 11 from the first buffer section 14, thereby improving the transfer success rate and success rate. It should be noted that the first propulsion mechanism 13 can be in the form of a cylinder or other types of propulsion mechanism. The specific manifestation of the first propulsion mechanism is not specifically limited here.

[0047] In one embodiment, please refer to Figure 7 The first sidewall 152 and the second sidewall 153 of the sample storage tank 15 are provided with a first through hole 154, which connects the first propulsion mechanism 13 and the first buffer section 14.

[0048] In one embodiment, the first through hole 154 is a U-shaped groove, and the first through hole 154 is disposed at the end of the bottom plate of the sample storage tank 15. The first propulsion mechanism 13 and the first buffer part 14 are located at the front and rear opening sides of the U-shaped groove of the first through hole 154.

[0049] In one embodiment, the first buffer section 14 is made of transparent material. A first barcode scanner 16 is also provided on the mounting base 172, and the first barcode scanner 16 is adapted to the first buffer section 14. Taking advantage of the transparent material of the first buffer section 14, when the target sample 11 is temporarily stored in the first buffer section 14, the first barcode scanner 16 acquires the barcode information of the target sample 11. The barcode information includes, but is not limited to, material grade, technical standard, test temperature, notch type, test item, sample number, and commission number. By setting up the first buffer section 14 and the first barcode scanner 16, the accuracy of the information of the target sample 11 can be ensured, avoiding incomplete or unclear information obtained directly from the sample storage slot 15 or during transportation, which could lead to abnormalities in subsequent processes and affect the test results.

[0050] In one embodiment, please refer to Figure 2 As shown, multiple sample buffer trays are also provided on the mounting base 172. The sample buffer trays include a first buffer tray 141, a second buffer tray 142, and a third buffer tray 143. The first buffer tray 141 is used to temporarily store the target sample 11 that needs to be stored at high temperature. The second buffer tray 142 is used to temporarily store the target sample 11 that needs to be tested at room temperature. The third buffer tray 143 is used to temporarily store the target sample 11 that needs to be stored at low temperature. If necessary, a fourth buffer tray 144 can also be set up. The fourth buffer tray 144 is used to temporarily store unclassified target samples 11. It is mainly used to temporarily store target samples when there is no space in the other three sample buffer trays. It should be noted that when the target sample 11 on the fourth buffer tray 144 needs to be transferred to the next area, the barcode information of the target sample 11 needs to be obtained again to avoid transferring the target sample 11 to an unsuitable insulation mechanism or sample buffer tray.

[0051] In one embodiment, please refer to Figure 5 and Figure 6 The sample buffer tray includes a first lifting mechanism 1401, a sample tray 1402, and a sample baffle 1403. The sample tray 1402 and the sample baffle 1403 form a first inner cavity for accommodating the target sample 11. At the same time, the sample tray 1402 is slidably connected to the sample baffle 1403 and is connected to the first lifting mechanism 1401. The sample tray 1402 moves up and down in the first inner cavity under the drive of the first lifting mechanism 1401, thereby placing multiple target samples 11 in the first inner cavity for temperature pretreatment. After the temperature pretreatment is completed, the target sample 11 is taken out by moving the sample tray 1402 upward and transferred to the impact testing machine 3 by the first robotic arm 4.

[0052] In one embodiment, in order to facilitate the statistical analysis of the test results of the target sample 11 after the test, barcode information is provided at both ends of the target sample 11. The two ends of the first buffer section 14 are made of transparent material. The first barcode scanner 16 is set in an area that is compatible with one end of the first buffer section 14. Preferably, the first barcode scanner 16 is set in the area where the second end of the first buffer section 16 is located, and the second end is on the side away from the first push mechanism 13.

[0053] In one embodiment, please refer to Figure 8 The transfer mechanism includes a first robotic arm 4 and a matching first transmission mechanism 41. The first robotic arm 4 is mounted on the first transmission mechanism 41 and can reciprocate along the transmission direction of the first transmission mechanism 41. The first robotic arm 4 transfers the target sample 11 on the first buffer section 14 to the corresponding heat preservation mechanism of the pretreatment mechanism 2. The heat preservation mechanism includes a low-temperature first heat preservation mechanism 21, a high-temperature second heat preservation mechanism 22, and a first fixing frame 23. Multiple first heat preservation mechanisms 21 and multiple second heat preservation mechanisms are fixed on the corresponding areas of the first fixing frame 23. The heat preservation mechanism can be understood as a heat preservation box with heat preservation function. The specific requirements for the structure of the heat preservation mechanism are not specified here. By setting the first transmission mechanism 41, the movement stroke of the first robotic arm 4 can be increased, while the arm length of the first robotic arm 4 can be shortened, which helps to improve the space utilization of the test equipment.

[0054] In one embodiment, please refer to Figure 7 and Figure 9 The first auxiliary mechanism 12 includes a first slide 121 and a movable baffle. The movable baffle is the front plate 151 of the sample storage tank 15. The bottom plate of the sample storage tank 15 is provided with a first guide groove 155. The front plate 151 is connected to the first slide 121 through the first guide groove 155. The front plate 151 moves along the length direction of the first guide groove 155 under the drive of the first slide 121, that is, along the length direction of the sample storage tank 15, thereby gradually pushing the target sample 11 at the front end of the sample storage tank 15 to the first target area at the end of the sample storage tank 15. It should be noted that the control method of the first slide 121 can be that the motor controls the lead screw to drive the first slide 121 to move back and forth on the guide rail, or other driving methods, which are not specifically limited here.

[0055] In one embodiment, please refer to Figure 9The first auxiliary mechanism 12 also includes a first mounting plate 173, which is fixed on the mounting base 172. The plane of the first mounting plate 173 and the horizontal plane of the mounting base 172 are at an angle δ, where 0° < δ < 90°. The first mounting plate 173 makes the sample storage tank 15 at an angle δ with the horizontal plane. When there is a target sample 11 in the sample storage tank 15, after the target sample 11 in the first target area is pushed into the first buffer section by the first propulsion mechanism 13, the target sample 11 in the sample storage tank 15 enters the first target area under the action of gravity. The first mounting plate 173 combined with the first auxiliary mechanism 12 can reduce the energy consumption of the first auxiliary mechanism 12 in pushing the front plate 151 to move.

[0056] In one embodiment, please refer to Figure 10 and Figure 11 The transfer mechanism includes a second transfer mechanism 31, which is located at the bottom of the test chamber 32 of the impact testing machine 3. The second transfer mechanism 31 is used to transfer the waste material of the target sample 11 after the test out of the test chamber 32. The test chamber 32 is provided with a test fixing part 321, a hammer 322, and a second barcode scanner 323. The second barcode scanner 323 is installed on the test fixing part 321. The test fixing part 321 is used to install the target sample 11 to be tested. The hammer 322 is used to impact the target sample 11. The second barcode scanner 323 is used to obtain the barcode information of the target sample 11 to be tested on the test fixing part 321. By verifying the barcode information obtained by the first barcode scanner 16 and the second barcode scanner 323, the information of the target sample 11 to be tested is determined, thereby improving the reliability of the test.

[0057] In one embodiment, please refer to Figure 11 It also includes a waste guide trough 5, a waste collection tray 6, and storage positions for storing the waste collection tray 6. The storage positions include a first storage position 61 and a second storage position 62. The first storage position 61 is used to store unused waste collection trays 6, and the second storage position 62 is used to store used waste collection trays 6. When the waste collection tray 6 placed at the end of the waste guide trough 5 needs to be replaced, the robot directly clamps the unused waste collection tray 6 from the first storage position 61 to replace it, and places the replaced used waste collection tray 6 in the second storage position 62. After all samples have been tested, they are transported together.

[0058] In one embodiment, please refer to Figure 4 It also includes a first camera 19, which is mounted on the mounting base 17. The first camera 19 is used to acquire image information of the target sample 11 and determine the impact position of the target sample 11 during the Charpy pendulum test through the image information, so as to facilitate the correct installation of the target sample 11 on the experimental fixing part 321.

[0059] The present invention provides an automatic impact device and equipment for multi-temperature Charpy test of metallic materials, including a sample feeding mechanism (1), a pretreatment mechanism (2), an impact testing machine (3), and a transfer mechanism. The transfer mechanism is used to transfer the target sample (11) through each link, reducing human intervention, thereby improving test efficiency and reducing human error. In addition, the sample feeding mechanism (1) is provided with a first auxiliary mechanism (12), a first propulsion mechanism (13), and a first buffer section (14) adapted to the first propulsion mechanism (13). The first auxiliary mechanism (12) is used to move the target sample (11) to be tested in the sample feeding mechanism (1) to the first target area of ​​the target sample (11) storage area of ​​the sample feeding mechanism (1). Then, the first propulsion mechanism (13) is used to push the target sample (11) in the first target area to the first buffer section (14) for easy access by the transfer mechanism. Thus, the target sample (11) does not need to be manually fed and unloaded when performing Charpy impact test, reducing errors caused by human intervention and improving test efficiency.

[0060] Example 2

[0061] Please see Figure 12 The present invention, based on the automatic impact device for multi-temperature Charpy testing of metallic materials in Example 1, also provides an automatic impact method for multi-temperature Charpy testing of metallic materials, the method comprising:

[0062] S1: In response to the first test command for testing the parameters of metallic materials, barcode information is added to the target position of the initial sample to obtain the first sample;

[0063] Specifically, the initial sample (the target sample mentioned above) has external dimensions of 10mm × 10mm × 55mm, and a metal material with a V-shaped or U-shaped notch in the middle of one side. Technicians add barcode information to the initial sample to be tested at the designated location. The barcode information includes material grade, technical standard, test temperature, notch type, test item, sample number, and commission number. Barcode information is set at both ends of the initial sample. Setting barcode information at both ends reduces position calibration during subsequent transportation and improves the acquisition of barcode information of the target sample by the first and second barcode scanners. For ease of understanding, the initial sample with barcode information is referred to as the first sample.

[0064] S2: In response to the second test command for the parameter test of the target sample, the first sample in the first target area is transferred to the first buffer unit, and an information entry command is generated;

[0065] In one embodiment, S2 includes:

[0066] S21: In response to the second test command, control the first auxiliary mechanism to sequentially advance the first sample in the sample storage tank to the first target area;

[0067] S22: Control the first propulsion mechanism to push the first sample in the first target area to the first buffer section, and generate the information entry instruction.

[0068] In one embodiment, S22 includes:

[0069] S221: In response to the second test command, obtain sample information of the first target area;

[0070] S222: When the presence of the first sample in the first target area is detected, the first propulsion mechanism is controlled to push the first sample to the first buffer section, and the information entry instruction is generated.

[0071] Specifically, when the controller receives the second test command, it controls the infrared or radar detector or image sensor to detect whether the first sample exists in the first target area. If it exists, it controls the first propulsion mechanism to push the first sample in the first target area to the first buffer section. If the first sample does not exist in the first target area, it controls the first auxiliary mechanism to push the first sample in the sample storage tank to the first target area. The above operation is repeated until all the first samples in the sample storage tank are transferred out of the sample storage tank.

[0072] S3: According to the information input instruction, control the first barcode scanner to collect the barcode information of the first sample and generate a temperature preprocessing instruction;

[0073] Specifically, when the first sample is detected to be pushed to the first buffer section, the first barcode scanner collects the barcode information located at the end of the first sample and records it as the first information, such as the temperature information of the first sample that needs to be pre-treated. Based on the temperature information, the first sample is transferred to the corresponding area and a temperature pre-treatment instruction is generated.

[0074] S4: According to the temperature pretreatment instruction, retrieve the temperature information of the barcode information, send the first sample into the heat preservation mechanism adapted to the temperature information for heat preservation pretreatment, obtain the second sample and generate the third test instruction.

[0075] Specifically, the insulation mechanism includes a first insulation mechanism for high-temperature pretreatment and a second insulation mechanism for low-temperature pretreatment. When the temperature information of the first sample indicates that high-temperature pretreatment is required, the first sample is sent to the first insulation mechanism for insulation treatment. If the temperature information of the first sample indicates that low-temperature pretreatment is required, the first sample is sent to the second insulation mechanism for insulation pretreatment. After the first sample completes the insulation pretreatment, a third test command is generated. The third test command is used to control the second sample, which has completed the temperature pretreatment, to be sent to the impact testing machine for Charpy pendulum test.

[0076] In one embodiment, S4 further includes:

[0077] S41: In response to the temperature preprocessing command, acquire a first image of the first sample;

[0078] S42: Determine the target area for the Charpy impact test of the first sample based on the imaging information of the target area in the first image;

[0079] S43: After the target area is determined, the first sample is sent to a heat preservation mechanism adapted to the temperature information of the barcode information for heat preservation pretreatment to obtain the second sample.

[0080] Specifically, after the first sample leaves the first buffer section, during the temperature pretreatment or Charpy impact test of the first sample, the first camera is controlled to acquire the first image information of the target sample, and the first image is compared with multiple reference images of the target sample pre-stored in the image library. Based on the comparison result, the state of the target area of ​​the target sample is determined, wherein the target area is the hammer impact position of the Charpy impact test, and the imaging state of the target area includes, for example: Figure 13 The four cases shown assume Figure 13 Image A shows the imaging result of the predetermined target sample. If the first image shows a different imaging result, the target sample is flipped until the first image matches the target sample. Figure 13 It matches Figure A in the diagram.

[0081] S5: According to the third test instruction, verify the barcode information of the second sample and control the impact testing machine to perform a Charpy impact test on the second sample.

[0082] Specifically, after the temperature pretreatment is completed, the second sample to be tested is installed in the test chamber, and the second barcode scanner is controlled to acquire the barcode information of the second sample again, which is recorded as the second information. The second information is compared with the first information. If the first information and the second information are consistent, the second sample is tested.

[0083] The present invention provides an automated impact method for multi-temperature Charpy testing of metallic materials. After adding barcode information to both ends of the target sample, a first auxiliary mechanism pushes the target sample into a first target area. Upon detection of the target sample in the first target area, a first propulsion mechanism pushes the target sample into a first buffer section, and a first robotic arm transfers the target sample. Simultaneously, a first barcode scanner is installed in the first buffer section, and a second barcode scanner is installed inside the impact testing machine to acquire the barcode information of the target sample. Based on the first information acquired by the first barcode scanner, the target sample is transferred to a corresponding insulation mechanism for pre-processing. By comparing the first information acquired by the first barcode scanner and the second information acquired by the second barcode scanner, the consistency of the test information for the target sample is ensured. This invention reduces human interference in Charpy pendulum testing, achieves fully automated operation, and improves experimental efficiency and accuracy.
