Description

Technical Field

[0001] The invention relates to the technical field of material detection, and in particular to an intelligent molding sand strength testing machine. Background Art

[0002] Molding sand is a material used to make molds in the metal casting process, usually composed of mineral sand, binders and other additives. It has a wide range of applications, including the automotive industry, aerospace, machinery manufacturing, construction and other fields. According to different casting requirements, the performance requirements of the molding sand will also change accordingly. Therefore, before casting, the performance of the molding sand needs to be adjusted to ensure the casting quality. The properties of molding sand mainly include compressive strength, tensile strength, bonding strength, thermal stability, impact strength, etc. In order to obtain accurate molding sand performance, generally the same batch of molding sand needs to be measured multiple times and then the average value is calculated to obtain accurate data.

[0003] In the prior art, a Chinese invention patent with announcement number CN115931573B provides an efficient molding sand detection device, which mainly includes a test box, a feeding mechanism is provided above the test box, and a transfer mechanism is provided below the feeding mechanism, etc. Its advantages are: it can detect the molding sand quickly and efficiently, not only can the molding sand be screened before the molding sand detection to speed up the feeding speed, but also the scattered molding sand can be collected during the molding sand detection process for easy cleaning. However, its disadvantages are: since the measurement of the molding sand needs to be carried out multiple times, it is necessary to ensure that the compactness and volume of the molding sand tested each time are consistent, but the device can only compact the molding sand manually, and the volume of the molding sand squeezed each time is different, so the volume and compactness of the molding sand test block tested each time are different, and the accurate molding sand performance value cannot be obtained after multiple measurements; on the other hand, after the device tests the molding sand test block, the molding sand is likely to remain on the bottom plate, so it is easy to make the data inaccurate in the next test.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific embodiments.

[0033] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0034] Example: Figure 1-Figure 5 , Figure 8As shown, a crushing component 2, a quantitative compacting component 3, a driving component 4, and a cleaning component 5 are arranged on the base 101. The crushing component 2 is used to crush the compacted molding sand, the quantitative compacting component 3 is used to quantitatively extrude the molding sand to manufacture the molding sand test block, the driving component 4 is used to control the movement of the cleaning component 5, and the cleaning component 5 is used to support the molding sand test block for detection, and automatically clean and collect the crushed molding sand test block; the crushing component 2 includes a molding sand tray 202, the molding sand tray 202 is fixedly connected to the bracket II 106, and a plurality of connecting rods I 206 are fixedly connected to the molding sand tray 202, the connecting rod I 206 is slidably connected to the valve unit 207, and the valve unit 207 is rotatably connected to the connecting rod II 2 08. Multiple connecting rods II 208 are fixedly connected to the valve gear ring 209, and the opening and closing states of multiple valve units 207 are controlled by rotating the valve gear ring 209; the valve gear ring 209 is respectively matched with the arc-shaped rack I 305 and the arc-shaped rack II 306; multiple connecting rods I 204 are rotatably connected to the molding sand disc 202, one of the connecting rods I 204 is fixedly connected to the gear I 205, and the gear I 205 is always meshed with the gear II 304, and the molding sand box 201 is respectively rotatably connected to the multiple connecting rods I 204, and the molding sand box 201 is provided with multiple through holes, and the molding sand disc 202 is provided with multiple crushing pieces 203, and the molding sand box 201 and the crushing pieces 203 are formed in cooperation. Put the molding sand into the molding sand box 201, and rotate the gear I 205 to make the connecting rod I 204 rotate, so that the molding sand box 201 starts to revolve. When the molding sand box 201 rotates, the molding sand in the molding sand box 201 will flow out into the molding sand tray 202 through the through hole at the bottom thereof. Since the molding sand box 201 is in contact with the crushing piece 203, the compacted molding sand will be crushed by the crushing piece 203, and then the molding sand will slowly gather to the center and flow out through the valve unit 207; when the valve gear ring 209 is rotated, the connecting rod II 208 drives the valve unit 207 to move, and since the connecting rod I 206 slides on the valve unit 207, multiple valve units 207 are in an open state, and the molding sand can flow out at this time. When the valve gear ring 209 is rotated again to reset, the multiple valve units 207 are in a closed state, and the molding sand will no longer flow out.

[0035] like Figure 5-Figure 7As shown, the quantitative compacting component 3 includes a motor Ⅰ311, which is fixedly connected to the base 101, and the motor Ⅰ311 is fixedly connected to the main shaft 302, and the main shaft 302 is fixedly connected to the slide sleeve 310, and the slide sleeve 310 is provided with a closed slide, and the slide sleeve 310 is slidably connected to the slide sleeve 313, and the inner wall of the sliding sleeve 313 is fixedly connected to a slider, and the slider slides in the closed slide on the slide sleeve 310, and the sliding sleeve 313 is fixedly connected to the cam plate 303, and the cam plate 303 is provided with a cam groove, and the cam plate 303 is slidably connected to the bracket III 107, and the bracket III 107 is fixedly connected to the base 101, and the main shaft 302 is fixedly connected to the connecting plate Ⅰ301, and the two ends of the connecting plate Ⅰ301 are respectively fixedly connected to a quantitative cylinder Ⅰ307, and the quantitative cylinder Ⅰ307 is slidably connected The quantitative cylinder II 308 is slidably connected to the sealing bottom plate 312 on the quantitative cylinder II 308, and the sealing bottom plate 312 slides in the cam groove on the cam disc 303. The two quantitative cylinders II 308 are respectively fixedly connected to one end of the connecting plate II 309, and the connecting plate II 309 is rotatably connected to the sliding sleeve 313. The base 101 is fixedly connected to the bracket II 106, and the bracket II 106 is fixedly connected to the sealing cover 105, and the sealing cover 105 cooperates with the quantitative cylinder I 307. The base 101 is fixedly connected to the bracket I 104, and the bracket I 104 is fixedly connected to the detection cylinder 102. The detection cylinder 102 is fixedly connected to the detection pressure head 103, and the detection pressure head 103 is used to detect the molding sand test block. The connecting plate I 301 is fixedly connected to the arc rack I 305 and the arc rack II 306, and the main shaft 302 is fixedly connected to the gear II 304.In the initial state, the metering cylinder Ⅰ307 receives the molding sand flowing out of the molding sand box 201, and then the motor Ⅰ311 starts to rotate for the first quarter of a circle. During the first quarter of a circle: first, the arc rack Ⅰ305 drives the valve gear ring 209 to reset, that is, the molding sand in the molding sand tray 202 no longer flows out, and then the sealing cover 105 fits the upper end of the metering cylinder Ⅰ307. At this time, the slider on the sliding sleeve 313 starts to move from the lower end of the closed slide groove on the slide groove sleeve 310 to the upper end, that is, the sliding sleeve 313 Lift the connecting plate II 309, and the corresponding sealing bottom plate 312 still seals the bottom of the quantitative cylinder II 308, that is, at this time, the quantitative cylinder II 308 starts to squeeze the molding sand in the quantitative cylinder I 307 and the quantitative cylinder II 308 upwards. When the molding sand is squeezed, the first quarter turn is completed; then the motor I 311 starts to rotate the second quarter turn. In this process, the slider on the sliding sleeve 313 starts to move from the upper end of the closed slide groove on the slide groove sleeve 310 to the lower end, that is, the sealing cover 10 5 no longer covers the quantitative cylinder I 307, and the extruded molding sand test block is held up by the sealing bottom plate 312. When the second quarter circle is about to be completed, the sealing bottom plate 312 moves horizontally due to the action of the cam plate 303. At this time, the sealing bottom plate 312 no longer supports the molding sand test block, and the second quarter circle is completed. When the second quarter circle is completed, the molding sand test block falls and is stably caught by the supporting plate 509. Then the third quarter circle begins. At this time, the quantitative cylinder I 307 from which the molding sand test block is discharged is in the third stage, but the other quantitative cylinder I 307 is in the first stage (extruding molding sand); then the fourth quarter circle is rotated. At this time, the quantitative cylinder I 307 that has discharged the molding sand test block is close to the molding sand box 201, and the arc-shaped rack II 306 drives the valve gear ring 209 to rotate, that is, the quantitative cylinder I 307 that has discharged the molding sand test block rotates a full circle back to the initial position, and begins to receive the molding sand in the molding sand box 201 again, while the other quantitative cylinder I 307 is in the second stage (discharging the molding sand test block).

[0036] like Figure 9-11As shown, the driving component 4 includes a bracket IV403, the bracket IV403 is fixedly connected to the base 101, the bracket IV403 is fixedly connected to the motor II401 and the bracket V404, the bracket IV403 is rotatably connected to the adjusting gear ring 406, the motor II401 is fixedly connected to the crank I407, the crank I407 is rotatably connected to the bracket IV403, the crank I407 is rotatably connected to the gear III408, and the gear III408 is meshed with the adjusting gear ring 406 The gear III 408 is fixedly connected to the crank II 410, and the crank II 410 is rotatably connected to the transverse block 409. The transverse block 409 is slidably connected to the slide rail frame 405, and the slide rail frame 405 is slidably connected to the bracket V 404. The slide rail frame 405 is fixedly connected to the longitudinal slider 506; the base 101 is fixedly connected to the driving cylinder 402, and the driving cylinder 402 is fixedly connected to the adjusting rack 411, and the adjusting rack 411 is meshed with the adjusting gear ring 406. The rotation of motor II 401 causes crank I 407 to rotate, and the rotation of crank I 407 causes gear III 408 to revolve. Since gear III 408 is meshed with adjusting gear ring 406, gear III 408 will also rotate. The rotation of gear III 408 will cause crank II 410 to rotate synchronously. The rotation of crank II 410 will cause the transverse block 409 to drive the slide rail frame 405 to slide on bracket V 404, and the transverse block 409 will also slide on the slide rail frame 405. The adjusting rack 411 is extended by driving cylinder 402, and the adjusting rack 411 can drive the adjusting gear ring 406 to rotate, so as to adjust the movement amplitude of the slide rail frame 405. This design is to adapt to molding sand test blocks with different compactness.

[0037] like Figure 12-13As shown, the cleaning component 5 includes a longitudinal slider 506, which is slidably connected to the bracket Ⅰ104, and two limit columns 505 are fixedly connected to the longitudinal slider 506, and the two limit columns 505 are symmetrically arranged. The longitudinal slider 506 is rotatably connected to a support plate 509, and the support plate 509 is fixedly connected to a connecting rod Ⅱ507, and the connecting rod Ⅱ507 is fixedly connected to a tension spring 508, and the tension spring 508 is fixedly connected to the longitudinal slider 506. The limit column 505 is used to limit the swing of the connecting rod Ⅱ507, and the residual molding sand debris on the support plate 509 falls off by rotating the support plate 509; the bracket Ⅰ104 is slidably connected to the transverse guide frame 502, and the transverse guide frame 502 is fixedly connected to the triangular inclined block 504, and the triangular inclined block 504 is fixedly connected to the cleaning plate 503, and the support plate 509 is fixedly connected to a flip frame 510, and the flip frame 510 cooperates with the transverse guide frame 502 and the triangular inclined block 504 respectively. The longitudinal slider 506 is driven by the slide rail frame 405 to move up and down. In the initial state, when the quantitative cylinder II 308 begins to prepare to drop the molding sand and stone block, the support plate 509 begins to move up. When the support plate 509 is at the highest point, it begins to receive the molding sand test block dropped from the quantitative cylinder II 308, and then the support plate 509 begins to move down driven by the longitudinal slider 506 until the molding sand test block is completely separated from the quantitative cylinder II 308, and then the support plate 509 no longer moves down. At this time, the support plate 509 returns to the initial position, and then the detection cylinder 102 extends, so that the detection pressure head 103 begins to approach the molding sand test block, and then the molding sand test block is subjected to a strength test. When the test of the molding sand test block is completed, the molding sand test block is broken, and at this time the support plate 509 continues to move down to attach Figure 10 As an example, the flip frame 510 passes over the transverse guide frame 502, and then the flip frame 510 presses down the triangular inclined block 504, so that the triangular inclined block 504 drives the transverse guide frame 502 and the cleaning plate 503 to move horizontally to the right. During the transverse movement, the cleaning plate 503 will clean the side of the support plate 509 close to the cleaning plate 503, and then the support plate 509 will reset upward. At this time, the flip frame 510 will be blocked by the left side of the transverse guide frame 502. As the support plate 509 continues to rise, the flip frame 510 will drive the support plate 509 to rotate. At this time, the tension spring 508 is stretched, and when the flip frame 510 rotates ninety degrees, the tension spring 508 is stretched to the maximum value, and then the flip frame 510 continues to rotate. The tension spring 508 will accelerate the rotation of the flip frame 510 due to the contraction effect. At this time, the side originally cleaned by the cleaning plate 503 will be used to receive the molding sand test block, and then the support plate 509 returns to the initial position and then stops moving, and then operates in the same way.

[0038] Working principle: according to the required properties of the molding sand test blocks, the position of the chute sleeve 310 on the main shaft 302 is adjusted to adjust the compactness of the same batch of molding sand test blocks, and the molding sand material is poured into the molding sand box 201, and then the motor I 311 is started. At this time, the molding sand in the molding sand box 201 is crushed by the crushing piece 203 and flows into the quantitative cylinder I 307 and the quantitative cylinder II 308 through the valve unit 207. Then the sealing cover 105 covers the quantitative cylinder I 307, and the quantitative cylinder II 308 and the sealing bottom plate 312 move upward to compact the molding sand into a cylindrical shape, and then the sealing bottom plate 312 moves horizontally to discharge the cylindrical molding sand test blocks, and at the same time the support plate 509 rises to steadily catch the molding sand. The test block is then moved down by the support plate 509, so that the molding sand test block is completely separated from the quantitative cylinder II 308. At this time, the quantitative cylinder II 308 can be turned away to make way for the detection pressure head 103, and the detection pressure head 103 begins to squeeze the molding sand test block for detection. After the detection is completed, the support plate 509 continues to descend with the broken molding sand test block, and the cleaning plate 503 cleans one side of the support plate 509, and then the support plate 509 rises, and the support plate 509 rotates 180 degrees to dump the broken molding sand test block into the collecting box 501, with the cleaned side facing up, to prepare for the next round of testing. At this point, one test is completed, and then a batch of molding sand strength tests can be completed by repeating it continuously.

[0039] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
