Description

Technical Field

[0001] The invention relates to the technical field of top pressing equipment, in particular to a protective device for a six-sided top pressing machine. Background Art

[0002] The six-sided top press equipment mainly applies pressure to the inner center through the top hammer made of tungsten-cobalt alloy driven by the hydraulic piston, thereby compressing the synthetic material block placed in the center. In this way, it can ensure that the synthetic block is subjected to uniform external load, thereby forming a closed ultra-high pressure environment to achieve the effect of pressing into a synthetic material. Since the top hammer will include the alternating effects of tension, compression, shear and thermal stress in the synthetic diamond process, fatigue damage, process defects, improper top hammer calibration and incorrect placement of the synthetic block and other external factors will cause crack damage to the top hammer. Therefore, the prior art uses a magnetoresistive sensor to detect cracks on the hammer surface after operation to prevent the pressure in the cavity from leaking out after continuous operation and causing the top hammer to collapse, so as to achieve the purpose of protecting the top hammer. However, the generation of cracks is random. The processing method of the prior art through the whole-surface comparison collection cannot be calibrated at a fixed point according to the crack surface. It is subject to the influence of edge effects, crack orientation and length differences. It is difficult to accurately determine the damage condition by relying only on the magnetic field output signal of a large area, which is prone to measurement errors. Therefore, it is impossible to accurately determine the damage state of the top hammer and it is impossible to timely confirm the state of shutdown protection. Summary of the invention

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figure 1 - Figure 5 As shown, a protective device for a six-sided top press described in the present invention includes an installation shell 1 installed on the outside of the six-sided top press, and a signal controller 2, a protection signal harness terminal 3, and a connecting harness group 4 are installed on one side of the installation shell 1. The signal controller 2 is connected to a detection axial calibration component 5, a three-item monitoring point debugging mechanism 6, and a self-locking signal response component 7 through the protection signal harness terminal 3 signal. The signal controller 2 is electrically connected to an external power supply through the connecting harness group 4. The detection axial calibration component 5, the three-item monitoring point debugging mechanism 6, and the self-locking signal response component 7 are all arranged on the inner side of the hammer pressure chamber of the six-sided top press, and the number of the three-item monitoring point debugging mechanism 6 is at least three.

[0021] In this embodiment, in order to solve the problem that the processing method of the prior art through whole-surface comparison and collection cannot perform fixed-point calibration according to the crack surface, and is easily subject to the influence of edge effects, crack orientation and length differences, which easily leads to measurement errors, the present invention proposes a protection device for a six-sided top press, which solves the above technical problems by setting an axial calibration detection component 5, a three-item monitoring point debugging mechanism 6 and a self-locking signal response component 7.

[0024] In this embodiment, after the top-pressing synthesis operation, the signal controller 2 sends a control command to the lateral switching slide rail 55, so that the lateral switching slide rail 55 drives the visual detection and collection part 53 to reach the top hammer position, and then switches the visual detection and collection part 53 through the longitudinal control rail 52 to an up-and-down staggered state to realize image collection of the entire coverage surface of the top hammer, wherein the visual detection and collection part 53 is an existing CCD image collector, and the visual detection and collection part 53 is connected to the visual detection end. After the visual detection and collection part 53 performs image collection, the visual detection end analyzes the crack generation position and the crack generation range, so that the operator debugs and controls the output end position of the magnetoresistive sensor 64 through the signal controller 2 according to the analysis results of the visual detection end. wherein, visual detection is a prior art means, not an improved content of the present invention, and in order to keep the image collected by the visual detection and collection part 53 stable, the longitudinal control rail 52 can debug the visual detection and collection part 53 to be symmetrically arranged up and down, so that the collection surface of the visual detection and collection part 53 covers the entire top hammer surface.

[0025] In an optional implementation of the present embodiment, the three-item monitoring point debugging mechanism 6 includes a drive motor 61, an extension mechanism 62, a fixed-distance limit slider 63 and a magnetoresistive sensor 64, the magnetoresistive sensor 64 is fixedly connected to the output end of the extension mechanism 62, the drive motor 61 and the fixed-distance limit slider 63 are both fixedly connected to the outer shell of the extension mechanism 62, and the output end of the drive motor 61 and the fixed-distance limit slider 63 are both slidably connected to the surrounding control bracket 54.

[0026] In this embodiment, after the visual detection and acquisition unit 53 obtains the crack generation area, the operator can control the magnetoresistive sensor 64 to debug the output point through the signal controller 2 according to the diameter of the image area. The debugging principle is: the magnetoresistive sensor 64 is driven by the driving motor 61 to debug the position along the axial direction of the surrounding control bracket 54, and the extension length of the magnetoresistive sensor 64 is debugged through the extension mechanism 62 according to the center point of the crack generation area as the symmetrical end point, so that even when the crack is not in the center plane state of the top hammer, the three groups of magnetoresistive sensors 64 can re-select the crack center point to set the three groups of magnetoresistive sensors 64 to an equilateral test spacing, so as to ensure the stability of the magnetic field output end, and then accurately confirm the damage state of the top hammer, so as to send a protection signal to the six-sided top press, so that the six-sided top press cannot continue to operate when the protection signal is not unlocked, so as to avoid continuing to operate without accurately knowing the current damage state, causing the pressure in the cavity to leak and cause the top hammer to collapse.

[0028] In this embodiment, when not in use, the transverse switching slide rail 55 can control the assembly bracket 51 to be stored outside the pressing chamber of the six-sided pressing machine to avoid interfering with the operating path of the pressing chamber. At the same time, when in use, the transverse switching slide rail 55 can be used to send the assembly bracket 51 into the pressing chamber.

[0029] In this embodiment, the transverse switching slide rail 55 is installed on the frame by a fixed connection to drive the assembly bracket 51 to reach the inner side of the top pressing chamber of the six-sided top press. The signal controller 2 uses a conventional controller. The signal controller 2 is connected to the longitudinal control rail 52, the visual detection and collection part 53, the drive motor 61, the extension mechanism 62 and the magnetic resistance sensor 64 through the protective signal harness end 3, and is used to control the activation and drive control of the above structure.

[0030] In this embodiment, the operating principle of the magnetoresistive sensor 64 is that the crack defect affects the distribution of the induced current on the surface of the top hammer, that is, the existence of the crack changes the path of the induced current emitted by the magnetoresistive sensor 64, thereby causing changes in the secondary magnetic field. Since this technology is a well-known technical means in the art and is not an improved content of the present invention, its specific principle will not be repeated in the present invention.

[0031] In an optional implementation of the present embodiment, the self-locking signal response component 7 includes an endpoint touch-pressure piece 71 and a pressure sensor 72. The endpoint touch-pressure piece 71 is arranged on the inner side of the hammer pressure chamber of the six-sided top press. The pressure sensor 72 is fixedly connected to the surrounding control bracket 54. After the non-application adjustment rail lateral switching slide rail 55 drives the surrounding control bracket 54 to move laterally to the detection surface, the endpoint touch-pressure piece 71 triggers the enabling signal of the pressure sensor 72, and the signal transmission end of the pressure sensor 72 is connected to the signal controller 2 through the protective signal harness end 3.

[0032] In an optional implementation of the present embodiment, the connecting harness group 4 includes an intermediate signal line 41, a power supply harness 42 and a hub 43, the intermediate signal line 41 is connected to the signal controller 2, the power supply harness 42 is used to detect the power supply of the axial calibration component 5, the three-item monitoring point debugging mechanism 6 and the self-locking signal response component 7 to the external power supply end, and the hub 43 is fixedly connected to one side of the mounting shell 1, and the hub 43 is used to bundle the power supply harness 42.

[0033] In this embodiment, the longitudinal control rail 52, the visual detection and collection unit 53 and the transverse switching slide rail 55 are all electrically connected to the external power supply through the protection signal harness terminal 3, the drive motor 61, the extension mechanism 62 and the magnetic resistance sensor 64 are electrically connected to the external power supply through the protection signal harness terminal 3, the end point contact piece 71 and the pressure sensor 72 are electrically connected to the external power supply through the protection signal harness terminal 3, wherein the hub 43 is used for centralized binding when the power harness 42 is connected to an external power supply.

[0034] In an optional implementation of the present embodiment, a limiting groove 541 is provided in the surrounding regulating bracket 54, one end of the fixed-distance limiting slider 63 extends to the inner side of the limiting groove 541, and the fixed-distance limiting slider 63 is slidably connected to the limiting groove 541. In an optional implementation of the present embodiment, the output end of the driving motor 61 is fixedly connected to the output shaft transmission part 611, and one end of the output shaft transmission part 611 extends to the inner side of the surrounding regulating bracket 54.

The transmission gear arranged at the end of the output shaft transmission part 611 and the rack arranged on the inner side of the surrounding regulating bracket 54 are meshed and transmitted to realize the debugging of the position of the magnetoresistive sensor 64. The specific debugging principle is: the output shaft transmission part 611 is driven to rotate by the driving motor 61, so that the output shaft transmission part 611 moves along the distribution path of the rack on the inner side of the surrounding regulating bracket 54 under the action of rotation. After moving to the desired position, the driving motor 61 stops driving, and the output end position of the magnetoresistive sensor 64 is further adjusted by extending or contracting the output end of the extension mechanism 62.

[0036] The working principle of the present invention is: after the six-sided top pressing machine completes the top pressing operation, it performs protection detection. First, the signal controller 2 controls the lateral switching slide rail 55 to drive the assembly bracket 51 to move horizontally until the end point contact pressure piece 71 reaches the set position of the pressure sensor 72. The assembly bracket 51 enters the inner side of the top pressing chamber and covers the top hammer, and at the same time triggers the activation signal of the pressure sensor 72. At this time, the visual detection collection part 53 and the surrounding control bracket 54 are in an activated state, and the signal controller 2 can control the longitudinal control rail 52, the drive motor 61 and the extension mechanism 62 to approve the crack generation surface. At the same time, the pressure sensor 72 sends a shutdown locking signal to the signal controller 2, that is, when the end point contact pressure piece 71 triggers the pressure sensor 72, the six-sided top pressing machine cannot continue to operate, so as to avoid the misoperation of the six-sided top pressing machine. When the output end of the magnetic resistance sensor 64 is debugged, the signal controller 2 controls the longitudinal control rail 52, the drive motor 61 and the extension mechanism 62 to verify the crack generation surface. Toward the regulating rail 52, the longitudinal regulating rail 52 drives the two groups of visual detection and collection parts 53 to be in an up and down staggered state to realize image collection of the entire coverage surface of the top hammer, obtain the crack generation area, and drive the magnetoresistive sensor 64 through the driving motor 61 to adjust the position along the axial direction of the surrounding regulating bracket 54 according to the diameter of the area, and adjust the extension length of the magnetoresistive sensor 64 through the extension mechanism 62 according to the center point of the crack generation area as the symmetrical end point, so that even when the crack is not in the center surface state of the top hammer, the three groups of magnetoresistive sensors 64 can re-select the crack center point to set the three groups of magnetoresistive sensors 64 to an equilateral test spacing, ensure the stability of the magnetic field output end, and then accurately confirm the damage state of the top hammer, so as to send a protection signal to the six-sided top press by the signal controller 2, so that the six-sided top press cannot continue to operate when the protection signal is not unlocked, so as to avoid continuing to operate without accurately knowing the current damage state, causing the pressure in the cavity to leak and cause the top hammer to collapse.
