Description

Technical Field

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

[0002] The six-sided top press includes a main base and six groups of working cylinders; the six groups of working cylinders include a bottom working cylinder, four side working cylinders and a top working cylinder; a piston is installed inside each working cylinder; a pad and a top hammer are coaxially fixed to the telescopic end of the piston; a working chamber of the six-sided top press is formed between the top hammers; and pyrophyllite blocks are placed in the working chamber. "Blasting" is a common accident of the six-sided top press, and the common cause is that the pyrophyllite blocks have leakage defects when the top hammers are used for top pressing. Generally, defects of talc blocks can be found before they are placed in the working chamber and the top hammer applies pressure. However, during the top hammer pressing process, defects of talc blocks are blocked by the top hammers applied on six sides, making it difficult for workers to detect them in advance. Six groups of working cylinders use pistons to make the top hammers press against the talc blocks. After the talc blocks are pressed, the corners of the talc blocks will extend outward along the gaps between adjacent top hammers to form triangular sealing edges. If the triangular sealing edges are damaged and 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 prior art 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 detection device and method for the corner drop 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 hold 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 to make the six-sided top press 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 inner baffle extending upward is provided at 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 plate, and ensuring the detection stability of the detection device.

[0008] Furthermore, a guiding chamfer is provided on the inner edge of the top of the inner enclosure 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 up and down; 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 circumference of 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 talc falling on the test piece.

[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.

[0012] A detection method using the above-mentioned detection device for detecting the corner drop of pyrophyllite blocks on the six-sided top press comprises the following steps: ①The corners of the pyrophyllite block fall off Put the pyrophyllite block into the working chamber; start the six-sided top press; the six working cylinders of the six-sided top press extend outward to apply pressure to the working chamber; the corner of the pyrophyllite block falls off and rolls down along the top hammer of the bottom working cylinder; the top hammer itself is provided with an inclined surface to guide the falling corner; the corner of the pyrophyllite block rolling down moves toward the detection plate; ②The weighing sensor sends out an electrical signal The corners of the pyrophyllite blocks rolling down 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 top press; ③ Emergency stop of six-sided top press After receiving the electrical signal, the six-sided press machine immediately stops.

[0015] 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 a bottom working cylinder 01, and comprises a detection plate 1 and a weighing sensor 2 which surround the top hammer 02 of the bottom working cylinder 01; 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 ineffective; 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, and once an increase in weight 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.

[0016] Compared with the prior art, the present invention provides a detection device for the corner drop of talc blocks on a six-sided top press, which can detect the defects of the talc blocks during the top pressing process of the top hammer 02 to prevent the occurrence of the "blow-up" phenomenon.

[0017] 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 change in the detection value when receiving the corner of the pyrophyllite block, thereby improving the sensitivity of the detection device.

[0018] 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.

[0019] A closed inner baffle 12 extending upward is provided at 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, thereby ensuring the detection stability of the detection device.

[0020] A guide chamfer 121 is provided on the inner edge of the top of the inner enclosure 12 to guide the corner of the pyrophyllite block.

[0021] 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 up and down; 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.

[0022] The outer edge of the detection plate 1 is not provided with an outer stopper; this can speed up the removal efficiency of the pyrophyllite blocks and ensure the synthesis efficiency of the artificial diamond.

[0023] The working principle of this embodiment is as follows: the detection plate 1 is used to receive the fallen pyrophyllite corner blocks; the weighing sensor 2 monitors the weight on the detection plate 1 in real time when the top hammer 02 squeezes the pyrophyllite blocks. 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 "explosion". Weighing sensor 2 Several weighing sensors 2 are distributed around the bottom working cylinder 01 and the top hammer 02, so that the detection plate 1 is within the detection range in all horizontal directions, thereby improving the sensitivity of the detection device.

[0024] Embodiment 2: Embodiment 2 is basically the same as Embodiment 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 detector.

[0025] The weighing sensor 2 is arranged corresponding to the rectangular hole 321, so that the impact received by the weighing sensor 2 on the corner of the pyrophyllite block is guided to the support ring 32 to avoid being damaged.

[0026] The rectangular hole 321 is arranged in the middle of the support ring 32 to ensure that the top and bottom of the support ring 32 have sufficient contact area, thereby ensuring that the support ring 32 stably supports the annular plate 31 and the bottom working cylinder 01 stably supports the support ring 32.
