Description

Technical Field

[0001] The invention relates to the technical field of superhard material processing, in particular to an intelligent control system for surface treatment of cubic boron nitride. Background Art

[0002] Cubic boron nitride (CBN) is a superhard material with many excellent properties. It is used as a superabrasive to prepare cutting tools and grinding tools due to its high hardness, thermal stability and chemical inertness. It is widely used in processing various ferrous metal materials and alloys, as well as tough and difficult-to-process materials, bringing revolutionary changes to the machinery industry, and can obtain high grinding ratios and processing surface quality. With people's high attention to the application of cubic boron nitride, the improvement of cubic boron nitride surface treatment technology is particularly important. Nickel plating is a surface metallization method. It deposits a metal nickel layer on the abrasive surface through a self-catalytic oxidation-reduction reaction in the absence of current. Cubic boron nitride is an insulator non-metal layer and cannot directly catalyze the reaction, but after surface sensitization, activation and other treatments, it can cause the plating solution to react and deposit the coating. The nickel plating layer increases the roughness of the abrasive surface and improves the holding force of the resin binder on it. After nickel plating, it can also reinforce internal defects, improve the strength of the abrasive, reduce impact, and firmly combine the abrasive with the binder. The nickel plating layer plays an isolation and protection role for the abrasive to avoid oxidation and other chemical reactions.

[0003] In the existing cubic boron nitride surface treatment, during the plating process, the operator holds the container in hand, observes the reaction situation in the reactor, and then manually adds reactants into the reactor, and manually controls the change of the adding speed and quantity according to different times. The manual addition of reactants will inevitably cause differences in the consistency of plating quality, which cannot meet customer requirements and does not conform to the standardized operation mode of industrialized production.

The liquid level sensor monitors the capacity of the additive in the additive container in real time, and sends the monitoring data to the PLC, the PLC processes the received monitoring data, obtains multiple continuous additive changes and forms a plating process curve, and then displays the plating process curve on the interactive module, and compares it with the parameters in the historical plating process curve on the interactive module to determine the difference between the parameters of the plating process curve formed by the additive addition flow and the plating process curve required for production. The PLC adjusts the flow of the additive delivered from the additive container to the reactor through the regulating device, and adjusts until the plating process curve formed by the additive addition flow is the same as the parameters of the plating process curve required for production, thereby completing the intelligent control of the surface treatment of cubic boron nitride.

[0022] The interactive module adopts the Wecon P23102H human-machine interface, and the PLC adopts the OMRON CP1H-XA type. The PLC communicates with the Wecon P23102H human-machine interface through a 232 serial port data line. There are 40 preset process curves on the Wecon P23102H human-machine interface for selection. According to the cubic boron nitride (CBN) processing process of different particle sizes, the data is input into the corresponding curve number for setting and saving. Each process curve can be set with 20 time periods and corresponding liquid volumes. Each time interval Ti (i=1~20) (seconds) corresponds to the additive Qi (i=1~20) (liters); the time can be switched between seconds and minutes according to actual conditions. The real-time given value of the additive can automatically make corresponding processing as the time unit is switched. The liquid volume measurement unit is liter, which is the corresponding height h (mm) converted according to the bottom area S of the additive container. The height parameter is used as the control variable to indirectly control the capacity V, that is, V=S*h. Set the amount of liquid added according to the total amount of additives needed each time. The upper limit of the additive container is 40 liters of additives.

[0023] See also Figure 1 In another embodiment of the present invention, a liquid supply device 4 is provided on the additive container, and the PLC controls the liquid supply device 4 to supply additives to the additive container 3.

[0024] Specifically, the liquid level sensor uses a high-precision liquid level sensor to monitor the additive in the additive container in real time, and the PLC receives and processes the monitoring data transmitted by the high-precision liquid level sensor in real time, and controls the liquid supply device 4 to supply the additive to the additive container. The liquid supply device 4 includes a solenoid valve group and a water pump, and the water pump connects the additive container and the additive storage barrel through a connecting pipe. The solenoid valve group includes a solenoid valve, and one or more solenoid valves are installed on the connecting pipe. Each of the solenoid valves is connected to the PLC respectively.

[0026] Specifically, the actuator 6 includes a control motor, and the control motor drives the regulating device. The PLC drives the control motor through a driver, and the control motor drives the regulating device to adjust and control the adding speed, flow rate, and flow velocity of the additive, so that the regulating device completes the liquid volume control of the additive in each process section according to the various levels of parameters of the plating process curve, and the automatic control replaces the manual work of adding additives to the reactor, and automatically changes the adding speed and flow rate according to different time periods.

[0027] Before the surface treatment of cubic boron nitride begins, the corresponding process curve is selected through the setting of the Weicon P23102H human-machine interface, and converted into parameters and sent to the PLC. The PLC controls the liquid feeding device to feed liquid according to the parameters, and the detection device monitors the amount of liquid feeding. The PLC determines whether the amount of liquid feeding reaches the set value and whether it is ready. If so, the plating process is monitored in real time and the surface treatment of cubic boron nitride begins; the detection device monitors the change of the additive capacity in the additive container in real time, and the PLC determines whether the actual value of the additive supplied to the reactor is equal to the given value according to the change of the additive capacity. If not, the liquid feeding device is controlled to adjust the additive supplied to the additive container, and the actuator drives the regulating device to adjust the additive flow rate delivered from the additive container to the reactor, so that the actual value of the additive supplied to the reactor is equal to the given value.

[0028] See also Figure 1 In another embodiment of the present invention, the adjusting device includes a linear slide, a pipeline and a clamp, the pipeline connects the additive container 3 and the reactor 1, and the control motor drives the clamp to clamp or loosen the pipeline through the linear slide.

[0030] See also Figure 1 In another embodiment of the present invention, the interaction module includes a touch screen, and the touch screen is communicatively connected to the monitoring control module.

[0031] Specifically, the PLC compares the real-time plating process curve obtained based on the monitoring data transmitted by the high-precision liquid level sensor with the preset plating process curve on the touch screen, and then modifies the relevant parameters on the touch screen to form an instruction and send it to the PLC. The PLC controls the liquid feeding device and the actuator to adjust the adding speed, flow rate and flow velocity of the additive according to the instruction, so that the real-time plating process curve obtained by the monitoring data transmitted by the high-precision liquid level sensor is consistent with the preset plating process curve, thereby ensuring the accuracy of the plating process and the consistency of the product.
