Detailed Description
A method of improving the machinability of a ceramic rock plate, comprising the steps of:
s1, placing the ceramic rock plate on a workbench, scanning the ceramic rock plate by using an ultrasonic flaw detector, and detecting whether macrocracks exist in the ceramic rock plate or not;
s2, placing the ceramic rock plate which is free of macrocracks and has the detection result of S1 on a workbench, and dividing the ceramic rock plate into a plurality of detection areas;
step S3, respectively attaching one end of each stress strain gauge to the surface of each detection area, and respectively connecting the other end of each stress strain gauge to a host of the resistance strain gauge;
step S4, opening a host of the resistance strain gauge, clicking a balance button, detecting the surface deformation condition of the ceramic rock plate and recording data after the displayed numerical value is stable;
step S5, fixing the ceramic rock plate on the workbench, connecting a vibration exciter with a host of a vibration aging instrument, and enabling the ceramic rock plate to vibrate at high frequency through the vibration exciter to eliminate the residual stress of the ceramic rock plate;
and step S6, after the vibration exciter stops running, closing the vibration aging instrument, recording the data of the resistance strain gauge, taking down the stress strain gauge and completing the stress release of the ceramic rock plate.
According to the invention, the ultrasonic flaw detection technology is firstly used for carrying out flaw analysis on the ceramic rock plate, according to the ultrasonic flaw detection principle, sound waves can be reflected to different degrees under the condition that the sound waves pass through different media, the reflected signals are captured by a signal receiver, echo signals can be displayed on a display, so that whether cracks appear in the ceramic rock plate product and the depth and the position of the cracks can be judged, when the cracks are detected in the ceramic rock plate, calibration can be carried out on the surface of the ceramic tile, the processing process can avoid the area with cracks, and the risk of crack diffusion is reduced; then dividing the ceramic rock plate without the macrocracks into a plurality of detection areas, respectively attaching one end of a plurality of stress strain gauges to the surface of each detection area, respectively connecting the other end of each stress strain gauge to a resistance strain gauge, opening the resistance strain gauge, and carrying out strain monitoring on the detection area on the surface of the ceramic rock plate, wherein if the surface of the ceramic rock plate is slightly deformed, the stress strain gauges can be deformed along with the surface of the ceramic rock plate, and the resistance of the stress strain gauges is changed, so that the magnitude of current in a circuit is changed, and the resistance strain gauges can capture and display the weak change of current in the circuit, thereby indicating that the local area of the surface of the ceramic rock plate is deformed (because the plastic deformation degree of the ceramic material is not obvious, the method can amplify the plastic deformation of the ceramic material, and an observer can know the local deformation degree of the ceramic product); and then, the ceramic rock plate is vibrated at high frequency by a vibration exciter, the energy transmitted by the high-frequency vibration is utilized, the residual stress of the ceramic rock plate is combined to induce the lattice slippage of the ceramic material or the lattice distortion of other forms, the accumulation of the lattice slippage or the lattice distortion of other forms finally causes the plastic deformation of the material, the energy brought by the residual stress of the ceramic rock plate can be consumed in the process, the purpose of eliminating the residual stress of the ceramic rock plate is achieved, finally, the vibration aging instrument is closed, the data of the resistance strain instrument is recorded, and whether the residual stress is consumed and released or not can be verified.
The method for improving the machinability of the ceramic rock plate can eliminate the residual stress generated in the production process of the ceramic rock plate on the basis of not changing the original production formula of the ceramic rock plate, improves the machinability of the ceramic rock plate, does not need to add any toughening agent or toughening crystal into the ceramic material, has no influence on the properties of the ceramic rock plate such as color development, register, color mixing, transmittance and the like, effectively reduces the production cost of enterprises, and has wide applicability.
In step S3, when the other end of the stress strain gauge is connected to the main unit of the resistance strain gauge, the other end is connected to the main unit of the resistance strain gauge by any one of a 1/4 bridge connection method, a 1/2 bridge connection method, and a full bridge connection method.
Preferably, in the step S3, when the other end of the stress strain gauge is connected to the main unit of the resistance strain gauge, the connection is performed by using a 1/4 bridge connection method.
1/2 bridging mode is used for detecting a relatively large area and observing the deformation of the whole area, and full bridging mode is used for detecting the deformation condition of the whole ceramic rock plate, in the invention, 1/4 bridging mode is preferred for connection, because 1/4 bridging mode is a direct detection point, namely the deformation of a small part area, and the connection mode is simple, the expansion or contraction of the deformation of the detection area can be reflected more fully and more intuitively, the contraction or expansion degree of the detection area can be reflected, and the accuracy of the detection result is higher.
Preferably, in step S2, the detection area is rectangular, the length of the detection area is less than or equal to 250mm, and the width of the detection area is less than or equal to 250 mm.
Specifically, in the step S2, the ceramic rock plate which is detected to have no macrocracks in the step S1 is placed on a horizontal table, and is divided into a plurality of regions by marker pens, and when the stress strain gauges are attached to the surfaces of the detection regions, sufficient and intuitive deformation detection can be performed on the respective detection regions; when the 1/4 bridging method is used for detection, detection points are directly detected, namely deformation of a small part of area is detected, if the detection area is too large, detection errors are prone to occurring, the detection area is rectangular, the length of the detection area is less than or equal to 250mm, the width of the detection area is less than or equal to 250mm, and accuracy of detection results can be guaranteed.
Specifically, in step S3, one ends of the stress strain gauges are attached to the center of the surface of each detection region.
Specifically, in step S3, when one end of each of the stress strain gauges is attached to the center of the surface of each of the detection areas, the stress strain gauge is required to be attached to the surface of the ceramic rock plate, and therefore warping, hollowing, and the like cannot occur.
Specifically, in step S5, the entire ceramic rock plate is vibrated at high frequency by the exciter.
Because the fluctuation range of the resonant peak of the ceramic tile product is relatively small, the resonant peak of the ceramic rock plate is in a relatively narrow interval no matter whether deformation occurs or not, so as to ensure that the aging vibration frequency is in the resonant frequency, the effect of promoting stress release can be achieved, the purpose of aging vibration is to remove residual stress, when a large amount of residual stress exists on the surface of the ceramic tile, the residual stress has two ways of releasing, one is to promote dislocation slip of crystal grains in the material, the other is to ensure that the micro-cracks are stably expanded, the two can absorb energy brought by the residual stress, but the excitation level of the process is higher, the energy contained in the residual stress can not reach the excitation levels of the two, so the ceramic rock plate is required to generate resonance through aging vibration, the energy generated by the resonance acts together with the residual stress, and the dislocation slip of the crystal grains in the material is promoted, the micro-cracks can be expanded stably to a certain degree to eliminate residual stress, and in this state, when the external shearing force acts on the surface of the ceramic tile, the energy level of the micro-cracks cannot enable crystal grains in the material to generate dislocation slip or crack expansion, namely, the machinability of the ceramic rock plate is improved, so that the data measured in the steps S4 and S6 are data before and after high-frequency vibration, the deformation condition of the ceramic rock plate can be reflected, and whether the crystal grains in the ceramic rock plate generate dislocation and slip is verified.
Preferably, in the step S5, the vibration frequency of the high-frequency vibration is 4000r/min to 9000r/min, and the vibration time is 15min to 60 min.
In the step S5, the ceramic rock plate is vibrated at high frequency by the vibration exciter, the vibration frequency of the high-frequency vibration is 4000r/min to 9000r/min, the vibration time is 15min to 60min, the vibration frequency and the vibration time are within the range, and the deformation of the ceramic rock plate is obvious, which indicates that the range is the resonance range of the ceramic rock plate, the generated energy is maximum, if the vibration time is too short, the stress cannot be completely released, and if the vibration time exceeds 60min, the high-frequency vibration is continued, and the stress release effect is greatly weakened.
Specifically, in the step S5, the ceramic rock plate is fixed on the table using a C-clamp.
Through using the C type to press from both sides and fix ceramic rock plate on the workstation, avoid ceramic rock plate to take place the displacement when carrying out high-frequency vibration, guarantee ceramic rock plate the stability of placing when carrying out high-frequency vibration to guarantee the stress release effect of ceramic rock plate.

Rather, these embodiments are provided so that this disclosure will be thorough and complete.

In the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1, the names of the equipments used in the present embodiment are as follows: an OND50 digital ultrasonic flaw detector (used for detecting and calibrating the distribution and shape of the macrocracks inside the ceramic rock plate), a DM-YB1840-10hz resistance strain gauge (used for detecting the surface deformation degree of the ceramic rock plate), and an MIT-12K series full-automatic vibration aging instrument (used for aging vibration stress removal);
a method of improving the machinability of a ceramic rock plate, comprising the steps of:
step S1, placing the ceramic rock plate 10 on a horizontal workbench 1, scanning the ceramic rock plate 10 by using an ultrasonic flaw detector (OND50 digital ultrasonic flaw detector), and detecting whether macro cracks exist in the ceramic rock plate 10;
step S2, placing the ceramic rock plate 10, which is not macrocracks as a result of the detection in step S1, on the horizontal table 1, and dividing the ceramic rock plate 10 into a plurality of detection areas (only the division into 8 detection areas is shown in the figure, and the operation is not limited to the division into 8 detection areas);
step S3, respectively attaching one end of each stress strain gauge 2 to the center of the surface of each detection area, and respectively connecting the other end of each stress strain gauge 2 to a host of the resistance strain gauge 3 (1/4 bridging mode is selected);
step S4, opening a host of the resistance strain gauge 3, clicking a balance button, detecting the surface deformation condition of the ceramic rock plate 10 and recording data after the displayed numerical value is stable;
step S5, fixing the ceramic rock plate 10 on a workbench 1 by using a C-shaped clamp 6, connecting a vibration exciter 4 with a host of a vibration aging instrument 5, connecting a vibration end of the vibration exciter 4 with the ceramic rock plate 10, and enabling the whole ceramic rock plate 10 to vibrate at high frequency by the vibration exciter 4 to eliminate the residual stress of the ceramic rock plate 10;
and step S6, after the vibration exciter 4 stops running, closing the vibration aging instrument 5, recording the data of the resistance strain gauge 3, taking down the stress strain gauge 2, and completing the stress release of the ceramic rock plate 10.
Wherein the size of the ceramic rock plate is 700mm × 1500mm, the vibration frequency of the high-frequency vibration is 6000r/min in step S5, wherein fig. 2 shows data of each stress strain gage displayed by the resistance strain gage before the high-frequency vibration (step S4), fig. 3 shows data of each stress strain gage displayed by the resistance strain gage performing the high-frequency vibration for 30min in step S5, fig. 4 shows data of each stress strain gage displayed by the resistance strain gage performing the high-frequency vibration for 60min in step S5, wherein CH01 to CH20 respectively show data values of different detection regions (wherein a positive value represents that deformation occurring in the detection region is expansion and a negative value represents that deformation occurring in the detection region is contraction), as can be seen from fig. 2 and 3, the residual stress at a local position of the ceramic rock plate is large, and therefore the value of a part of the stress strain gage is greatly changed because the area of the ceramic rock plate is large, the condition of uneven heating in the kiln is particularly obvious, so the residual stress distribution of the surface after firing is large and uneven; as can be seen from fig. 3 and 4, the extreme difference of the change of the stress strain gauge number value is 19556 μ epsilon when the high-frequency vibration is carried out for 30min, and the extreme difference of the change of the stress strain gauge number value is still 19556 μ epsilon when the high-frequency vibration is carried out for 60min, which shows that the stress release effect is not obvious when the high-frequency vibration duration is increased after the vibration time reaches 60 min.
In addition, through comparison, after the ceramic rock plate sample which is easy to be cut and cracked is processed by the method for improving the machinability of the ceramic rock plate, the ceramic rock plate sample is not cut and cracked when being cut by the cutting machine, so that the aim of quickly removing the residual stress of the ceramic rock plate product can be fulfilled by aging vibration, and the production cost of enterprises is effectively reduced.
