Description

Technical Field

[0001] The present invention relates to the technical field of six-sided top press accessories, in particular to a device and method for detecting corner drop of pyrophyllite blocks on a six-sided top press. Background Art

[0002] The six-sided jacking press consists of a mainframe and six sets of working cylinders, including a bottom cylinder, four side cylinders, and a top cylinder. Each cylinder houses a piston. A spacer and an impact hammer are coaxially fixed to the piston's telescopic end. The space between the impact hammers forms the press's working chamber, where pyrophyllite blocks are placed. "Blow-up" is a common problem with six-sided jacking presses, often caused by leakage from the pyrophyllite blocks during the impact. Generally, defects in talc blocks can be discovered before they are placed in the working chamber and the top hammers are applied. However, during the top hammer application process, defects in the talc blocks are obscured by the top hammers on six sides, making it difficult for workers to detect them in advance. Six groups of working cylinders use pistons to force the top hammers to press the talc blocks. When the talc blocks are pressed, the corners of the talc blocks extend outward along the gaps between adjacent top hammers to form triangular sealing edges. If these triangular sealing edges are damaged or fall off, the talc blocks will leak, and the resulting "blow-up" phenomenon is difficult to prevent. The triangular sealing edges formed at the corners of the talc blocks are easily damaged and fall off. The existing technology does not have any solution to this "blow-up" phenomenon. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems and to provide a device and method for detecting the falling corners of pyrophyllite blocks on a six-sided top press.

[0004] The technical solution of the present invention is: a detection device for the falling corners of pyrophyllite blocks on a six-sided top press, which is arranged on the bottom working cylinder and includes a detection plate surrounding the top hammer of the bottom working cylinder and a weighing sensor; the detection plate is used to receive the fallen pyrophyllite corner blocks; an inner hole matching the bottom working cylinder is provided at the center of the detection plate to prevent the pyrophyllite corner blocks from falling from the gap between the inner hole and the top hammer, thereby rendering the detection device ineffective; the weighing sensor is arranged at the bottom of the detection plate and connected to the fixed end of the bottom working cylinder; the weighing sensor monitors the weight on the detection plate in real time when the top hammer squeezes the pyrophyllite block, and once an increase in weight is detected, an alarm signal is sent to the six-sided top press, causing the six-sided top press to stop urgently to prevent the occurrence of the "explosion" phenomenon.

[0005] Preferably, there are several weighing sensors evenly distributed at the bottom of the detection plate, so that each part of the detection plate can quickly produce a change in the detection value when receiving the corner of the pyrophyllite block, thereby improving the sensitivity of the detection device.

[0006] Furthermore, a plurality of weighing sensors are distributed around the circumference of the top hammer of the bottom working cylinder, so that all horizontal directions of the detection plate are within the detection range, thereby improving the sensitivity of the detection device.

[0007] Preferably, a closed upwardly extending inner baffle is provided on the edge of the inner hole to prevent the corners of the crushed talc blocks from filling the gap between the top hammer and the inner hole, hindering the vertical lifting of the detection disk, and ensuring the detection stability of the detection device.

[0008] Furthermore, the inner edge of the top of the inner enclosure is provided with a guide chamfer to guide the corners of the talc blocks.

[0009] Preferably, the detection device for the falling corners of the talc block on the six-sided top press also includes a bracket; the weighing sensor is connected to the fixed end of the bottom working cylinder through the bracket; the bracket includes an annular plate and a support ring connected upper and lower; the annular plate is connected to the weighing sensor; the support ring is connected to the upper end of the fixed end of the bottom working cylinder; the bracket provides a larger installation area to facilitate the arrangement and installation of the weighing sensor.

[0010] Furthermore, rectangular holes are distributed around the side wall of the support ring to reduce the structural strength of the support ring, so that the support ring can undergo a certain elastic deformation and cushion the impact of the corner of the pyrophyllite falling on the tester.

[0011] Furthermore, the weighing sensor is arranged corresponding to the rectangular hole, so that the impact received by the weighing sensor on the corner of the pyrophyllite block is guided to the support ring to avoid being damaged.

[0013] ①The corners of the pyrophyllite blocks fall off

[0015] ②The weighing sensor sends out an electrical signal

[0016] The corners of the pyrophyllite blocks rolling downward fall onto the detection plate; the weighing value of the weighing sensor increases; when the increase reaches a certain amount, the weighing sensor sends an electrical signal to the six-sided press;

[0031] Example 1: See Figure 1-5, a detection device for the falling corners of pyrophyllite blocks on a six-sided top press is arranged on the bottom working cylinder 01, and includes a detection plate 1 surrounding the top hammer 02 of the bottom working cylinder 01, and a weighing sensor 2; the detection plate 1 is used to receive the fallen pyrophyllite corner blocks; an inner hole 11 matching the bottom working cylinder 01 is provided at the center of the detection plate 1 to prevent the pyrophyllite corner blocks from falling from the gap between the inner hole 11 and the top hammer 02, thereby rendering the detection device invalid; the weighing sensor 2 is arranged at the bottom of the detection plate 1 and connected to the fixed end of the bottom working cylinder 01; the weighing sensor 2 monitors the weight on the detection plate 1 in real time when the top hammer 02 squeezes the pyrophyllite block. Once the weight increase is detected, an alarm signal is sent to the six-sided top press 00, causing the six-sided top press 00 to stop urgently to prevent the occurrence of the "explosion" phenomenon.

[0032] Compared with the prior art, the present invention provides a device for detecting the corner drop of pyrophyllite blocks on a six-sided top pressing machine, which can detect defects of the pyrophyllite blocks during the top pressing process of the top hammer 02 to prevent the occurrence of "explosion" phenomenon.

[0033] There are several weighing sensors 2, which are evenly distributed at the bottom of the detection plate 1, so that each part of the detection plate 1 can quickly produce a detection value change when receiving the corner of the pyrophyllite block, thereby improving the sensitivity of the detection device.

[0034] A plurality of weighing sensors 2 are distributed around the circumference of the bottom working cylinder 01 and the top hammer 02, so that all horizontal directions of the detection plate 1 are within the detection range, thereby improving the sensitivity of the detection device.

[0035] A closed, upwardly extending inner baffle 12 is provided on the edge of the inner hole 11 to prevent the crushed talc corners from filling the gap between the top hammer 02 and the inner hole 11, hindering the vertical lifting of the detection disk 1 and ensuring the detection stability of the detection device.

[0036] A guide chamfer 121 is provided on the inner edge of the top of the inner enclosure 12 to guide the corners of the pyrophyllite blocks.

[0037] The detection device for the falling corners of the talc block on the six-sided top press also includes a bracket 3; the weighing sensor 2 is connected to the fixed end of the bottom working cylinder 01 through the bracket 3; the bracket 3 includes an annular plate 31 and a support ring 32 connected upper and lower; the annular plate 31 is connected to the weighing sensor 2; the support ring 32 is connected to the upper end of the fixed end of the bottom working cylinder 01; the bracket 3 provides a larger installation area to facilitate the arrangement and installation of the weighing sensor 2.

[0038] The outer edge of the detection plate 1 is not provided with an outer stop; this can speed up the removal efficiency of the pyrophyllite blocks and ensure the synthesis efficiency of the artificial diamond.

[0039] The working principle of this embodiment is as follows: Detection tray 1 is used to catch fallen pyrophyllite corner blocks; load cells 2 monitor the weight of the detection tray 1 in real time as the top hammer 02 compresses the pyrophyllite blocks. Once an increase in weight is detected, an alarm signal is sent to the six-sided top press 00, causing it to stop suddenly to prevent "blow-ups." Several load cells 2 are distributed circumferentially around the bottom working cylinder 01 and the top hammer 02, ensuring that the detection tray 1 is within detection range in all horizontal directions, improving the sensitivity of the detection device.

[0040] Example 2: Example 2 is basically the same as Example 1, and the similarities are not repeated here. The difference is that rectangular holes 321 are distributed circumferentially on the side wall of the support ring 32, which reduces the structural strength of the support ring 32 and enables the support ring 32 to undergo a certain elastic deformation, thereby cushioning the impact of the corner of the talc falling on the tester.

[0041] The weighing sensor 2 is arranged corresponding to the rectangular hole 321, so that the impact received by the weighing sensor 2 from the corner of the pyrophyllite block is guided to the support ring 32 to avoid being damaged.

[0042] The rectangular hole 321 is set in the middle of the support ring 32 to ensure that there is sufficient contact area at the top and bottom of the support ring 32, thereby ensuring stable support of the annular plate 31 by the support ring 32 and stable support of the support ring 32 by the bottom working cylinder 01.

[0043] Example 3: A method for detecting the corner drop of pyrophyllite blocks on a six-sided top press using the device for detecting the corner drop of pyrophyllite blocks on a six-sided top press described in Example 1, comprising the following steps:

[0044] ①The corners of the pyrophyllite blocks fall off

[0045] Place the pyrophyllite block into the working chamber; start the six-sided top press 00; the six working cylinders of the six-sided top press 00 extend outward, applying pressure to the working chamber; the corners of the pyrophyllite block fall off and roll downward along the top hammer 02 of the bottom working cylinder 01; the top hammer 02 itself has an inclined surface to guide the falling corners; the rolling corners of the pyrophyllite block move toward the detection plate 1;

[0046] ②Weighing sensor 2 sends out an electrical signal

[0047] The corner of the pyrophyllite block rolling downward falls on the detection plate 1; the weighing value of the weighing sensor 2 increases, and the weighing sensor 2 sends an electrical signal to the six-sided top press 00; the real-time monitoring of the weighing sensor 2 is synchronized with the extension of the six working cylinders;

[0048] ③ Six-sided top press 00 emergency stop

[0049] After receiving the electrical signal, the six-sided top press 00 immediately stops.
