[0002] Electrical discharge machining refers to a method of machining a workpiece through the erosion effect of pulsed discharge between a tool electrode and a workpiece electrode in a certain medium. Electrical discharge machining is a method of machining using electricity and heat energy that began to be studied and gradually applied in production in the 1940s.

[0003] After retrieval, Chinese Patent No. CN201110253507.4 discloses a wire electrical discharge machining machine with the functions of automatic switching between constant temperature control and temperature difference control. The control unit cools the machining fluid according to the ambient temperature of the wire electrical discharge machining machine and the temperature of the machining fluid.

[0004] The beneficial effects of the above device are as follows: It can provide a wire electrical discharge machining machine, which has the function of automatically switching the control unit for cooling the machining fluid according to the ambient temperature of the wire electrical discharge machining machine and the temperature of the machining fluid in order to prevent condensation from occurring on the wire electrical discharge machining machine, and has a cooling device for cooling the machining fluid.

[0030] Preferably, a plurality of tank bodies are provided in the sedimentation tank, which are respectively used to store and precipitate the natural cold sources of different batches transported in the cold source circulation water path after use.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. Through the composition of the heat exchange type water cooler, machine tool group, cold source circulation water path, cooling system, water tank, and indoor integrated control system, the natural cold source is extracted and stored in the water tank in this solution, and then the natural cold source stored in the water tank is further refrigerated by the cooling system, so that the natural cold source can achieve the best heat exchange effect, and is transported to the heat exchange type water cooler through the cold source circulation water path. The heat exchange type water cooler uses the natural cold source to exchange heat and cool down the machine tool group, achieving the purpose of energy conservation and consumption reduction;

[0033] 2. In this solution, by installing the heat exchange type water chiller outside the factory, the heat exchange inside the factory is reduced, further reducing the impact of temperature on the machining accuracy of the machine tools. Moreover, multiple groups of heat exchange type water chillers are installed on the cold source circulating water path, and each group of heat exchange type water chillers corresponds to a machine tool group. At the same time, the heat exchange type water chiller and the indoor integrated control system are connected by remote signal control, realizing centralized cooling and centralized operation control of multiple machine tools on site by users, and remote operation and monitoring can also be achieved.

[0034] 3. In this solution, the heat exchange type water chiller consists of a filtration chamber, a cooling chamber and a purified water chamber. At least multiple filter tanks are arranged in the filtration chamber. Correspondingly, at least multiple water supply pumps are arranged in the purified water chamber. When a certain water pump or electrical component of the heat exchange type water chiller is damaged, it will not stop working completely, and partial zoning can work normally, thus avoiding equipment interruption and improving work efficiency.

[0035] 4. In this solution, a three-way valve is arranged on the cold source circulating water path. The natural cold source discharged by the heat exchange type water chiller can be re-discharged into the cold source circulating water path or the cooling pool through the three-way valve. The cooling pool is connected to the cold source inlet of the heat exchange type water chiller through a pipeline, so that the natural cold source in the cooling pool can also be re-introduced into the heat exchange type water chiller, which can increase the storage capacity of the natural cold source. At the same time, when the amount of natural cold source stored in the water tank cannot meet the cooling requirements of multiple machine tool groups, through the measurement of the temperature sensor, the temperature values of the machine tool groups are ranked according to priority, so that the machine tool group with a higher temperature has a higher priority than the machine tool group with a lower temperature. Further, the refrigerated natural cold source in the water tank is preferentially supplied to the machine tool group with a higher temperature, and the remaining natural cold source is sequentially supplied to the machine tool groups with lower temperatures. When the remaining amount is insufficient, the machine tool group circulates and uses the natural cold source in its corresponding cooling pool, further enabling multiple machine tool groups to exchange heat and cool down reasonably.

[0036] 5. In this solution, due to the arrangement of multiple cooling pools, the temperature of the natural cold source discharged by the heat exchange type water chiller in the machine tool group with a higher priority must be higher than the temperature of the natural cold source discharged by the heat exchange type water chiller in the machine tool group with a lower priority. At this time, the natural cold source discharged from the machine tool group with a lower priority is preferentially placed into the cold source circulating water path, and then re-transmitted to the water tank through the cold source circulating water path to be refrigerated by the cooling system, thereby reducing the energy consumption and time required for the cooling system to refrigerate. The natural cold source discharged from the machine tool group with a higher priority is preferentially discharged into the cooling pool for natural cooling, avoiding affecting the temperature of other natural cold sources in the cold source circulating water path and reducing the energy consumption required for the cooling system to refrigerate.

[0037] 6. In this solution, a sedimentation tank is set in the cold source circulation water path. When the natural cold source in the cold source circulation water path is recycled and put back into the water tank, it first undergoes sedimentation in the sedimentation tank. Further, when the natural cold source exchanges heat and refrigerates in the machine tool group, the medium in the natural cold source may be affected due to heat absorption, or impurities in the machine tool group may be absorbed during the heat absorption process, resulting in poor water quality of the natural cold source. This further leads to poor heat exchange effect and low cooling efficiency. By sedimenting in the sedimentation tank, impurities in the natural cold source can be filtered out after sedimentation, and further, the natural cold source can effectively cool the machine tool group.

[0038] 7. In this solution, a cold source water quality detection system and a cold source water quality purification system are set in the sedimentation tank. The cold source water quality detection system can detect the water quality of the natural cold source stored in the sedimentation tank. When the water quality is qualified and can be discharged, the natural cold source can be re-discharged to the surface layer or the underground layer, enabling the natural cold source to enter the natural environment through natural circulation. Thus, during the process of the heat exchanger liquid temperature control system extracting and utilizing the natural cold source, sustainable green production can be achieved without damaging the environment. And when the recycled natural cold source is unqualified, the cold source water quality purification system is used to purify the water quality of the natural cold source until the water quality is restored to the dischargeable level, and then the purified natural cold source is re-discharged. The unpurified natural cold source will be re-transmitted to the water tank for continuous use and effectively repaired and purified during idle time until it is discharged.

[0042] Embodiment 1

[0043] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0044] A new type of heat exchanger liquid temperature control system for an electric discharge machining machine, the heat exchanger liquid temperature control system is composed of a heat exchange water cooler, a machine tool group, a cold source circulation water path, a cooling system, a water tank, and an indoor integrated control system;

[0045] Among them, the cooling water stored in the water tank is all natural cold source. The natural cold source is pumped into the water tank for storage by a water pump. And a temperature sensor F is installed in the water tank to measure the temperature of the natural cold source stored in the water tank, so as to avoid the natural cold source being affected by external factors or the external environment during the extraction process, resulting in the natural cold source stored in the water tank not achieving the best heat exchange effect;

[0046] At the same time, the water tank is connected to the cooling system. After the temperature sensor F detects the current temperature of the natural cold source in the water tank in real time, it transmits the temperature information to the indoor integrated control system, enabling the user to judge whether the temperature of the natural cold source meets the requirements of heat exchange and cooling through the indoor integrated control system. If the refrigeration temperature of the natural cold source in the water tank does not meet the requirements of heat exchange and cooling, the natural cold source in the water tank is quickly artificially refrigerated through the cooling system, so that the natural cold source meets the heat exchange and cooling effect, and further improves the heat exchange efficiency of the liquid temperature control system of the heat exchanger;

[0047] The water tank is connected to the heat exchange type water coolers in multiple machine tool groups respectively through the cold source circulation waterway, enabling the user to dispatch the natural cold source in the water tank through the indoor integrated control system at the same time. Further, centralized cooling and centralized operation control can be carried out for multiple machine tool groups at the same time, and remote operation and monitoring can be realized.

[0048] The heat exchange type water cooler is composed of a filter chamber, a cooling chamber and a purified water chamber, where:

[0049] A cold source inlet and a cold source outlet are arranged on the cooling chamber and are respectively connected to the cold source circulation waterway, so that the natural cold source can enter the cooling chamber in the heat exchange type water cooler through the cold source circulation waterway, thus ensuring that there is always a stable supply of natural cold source in the heat exchange type water cooler and ensuring the heat exchange and cooling of the machine tool group by the heat exchange type water cooler;

[0050] A water supply port is arranged on the purified water chamber and is connected to the machine tool group, so that the water supply pump in the purified water chamber can transport the natural cold source in the cooling chamber to the machine tool group, and further carry out heat exchange and cooling on the machine tool group through the natural cold source;

[0051] A water return port is arranged on the filter chamber. When the natural cold source exchanges heat with the machine tool group, the natural cold source will absorb heat and impurities. At this time, the heat-absorbed natural cold source is filtered by the filter tank in the filter chamber, so that the impurities absorbed by the natural cold source during the heat exchange process are filtered out, further improving the purity of the natural cold source and ensuring that the heat exchange effect of the natural cold source is not affected. And when the filter chamber transports the heat-exchanged natural cold source to the cooling chamber, the heat-exchanged natural cold source stands still in the cooling chamber for a period of time, so as to quickly dissipate the heat absorbed by the natural cold source;

[0052] And a water temperature and water quality detection system is arranged in the purified water tank, which can detect the natural cold source used for multiple cycles, so as to judge whether the heat or water quality of the natural cold source meets the heat exchange and cooling effect;

[0053] When the natural cold source is circulated multiple times in the heat exchange type water cooler, if the water quality or temperature of the natural cold source cannot achieve the heat exchange and cooling effect, it is discharged through the cold source water outlet and then re-introduced into the cold source circulation water path, and then a new natural cold source is added through the cold source circulation water path, so as to improve the heat exchange and cooling effect of the heat exchange type water cooler.

[0054] At least four groups of filter tanks are arranged in the filter chamber of the heat exchange type water cooler. Correspondingly, at least four groups of water supply pumps are arranged in the purified water chamber, so that when a certain water pump or electrical component of the heat exchange type water cooler is damaged, it will not stop operating completely, and partial zoning can work normally;

[0055] An electric control box is arranged on the heat exchange type water cooler and is signal-transmission connected to the indoor integrated clamping system, so that users can know the working state of the heat exchange type water cooler remotely, check the modules in the heat exchange type water cooler, and at the same time can judge the data detected by the water temperature and water quality detection system, realizing real-time data monitoring and remote operation.

[0056] Install the heat exchange type water cooler outside the factory to reduce the heat exchange inside the factory and further reduce the influence of temperature on the machining accuracy of the machine tool group.

[0057] A temperature sensor A is arranged in the machine tool group. Through the temperature sensor A, the temperature during the operation of the machine tool group can be detected in real time, and the temperature data is further transmitted to the indoor integrated control system, so that users can remotely control the liquid temperature control system of the heat exchanger, and further use the corresponding heat exchange type water cooler to cool down the overheated machine tool group by heat exchange.

[0058] The water temperature and water quality detection system in the heat exchange type water cooler includes a temperature sensor B. The temperature of the natural cold source in the heat exchange type water cooler is detected through the temperature sensor B. When the temperature sensor B detects that the temperature of the natural cold source can effectively and quickly exchange heat with the machine tool group, the heat exchange type water cooler starts to operate, so that the natural cold source quickly cools down the machine tool group. If the temperature sensor B detects that the temperature of the natural cold source cannot quickly exchange heat with the machine tool group, the natural cold source in the heat exchange type water cooler is discharged, placed in the cold source circulation water path, and then a new natural cold source with a lower temperature is placed through the water tank to achieve rapid cooling again;

[0059] And a temperature sensor F is provided in the water tank. Through the temperature sensor F, the real-time temperature of the natural cold source in the water tank can be detected. If the temperature value of the natural cold source in the water tank cannot achieve rapid cooling of the machine tool group, the cooling system automatically refrigerates the natural cold source in the water tank, making the temperature of the natural cold source in the water tank lower, so that it can absorb heat and cool down more quickly during the heat exchange process.

[0060] A temperature sensor C is provided at the cold source water inlet of the heat exchange type water cooler in the cold source circulation water path, which can detect the temperature of the natural cold source newly placed in the heat exchange type water cooler in real time. When the temperature difference between the natural cold source in the circulation water path detected by the temperature sensor C and the natural cold source in the heat exchange type water cooler detected by the temperature sensor B is not large, no new natural cold source is placed into the heat exchange type water cooler to avoid the overall temperature rise caused by the mixing of natural cold sources at different temperatures, further resulting in poor heat exchange and cooling effect.

[0061] A temperature sensor D is provided at the cold source water outlet of the heat exchange type water cooler in the cold source circulation water path. When the heat exchange type water cooler discharges the used natural cold source, the temperature of the discharged natural cold source is detected through the temperature sensor D. If the temperature of the discharged natural cold source will not affect other natural cold sources in the cold source circulation water path, further enabling the discharged natural cold source to be re-placed into the water tank through the cold source circulation water path for static cooling and facilitating subsequent recycling;

[0062] At the same time, a plurality of three-way valves are provided on the drainage pipeline of the cold source circulation water path, corresponding to a plurality of heat exchange type water coolers on the cold source circulation water path respectively. When the temperature sensor D detects that the temperature of the natural cold source discharged from the heat exchange type water cooler is relatively high, the natural cold source is placed into the cooling pool through the three-way valve, so that the natural cold source cools down in the cooling pool. And a temperature sensor E is provided in the cooling pool to detect the temperature of the natural cold source to be cooled in the cooling pool until the temperature can be re-discharged into the cold source circulation water path;

[0063] And the cooling pool is connected to the cold source water inlet of the heat exchange type water cooler through a pipeline, so that the natural cold source in the cooling pool can also be re-placed into the heat exchange type water cooler to achieve heat exchange and cooling.

[0064] By providing corresponding and independent cooling pools in the pipelines of each heat exchange type water chiller, the storage capacity of natural cold sources can be increased. When the natural cold sources stored in the water tank supply cooling for multiple machine tool groups simultaneously, if the amount of natural cold sources stored in the water tank cannot meet the cooling requirements of multiple machine tool groups and the cooling system cannot promptly refrigerate the newly pumped natural cold sources in time, temperature detection is carried out through temperature sensor A in each machine tool group. Priority ranking is performed based on the temperature values of the machine tool groups, such that the machine tool group with a higher temperature has a higher priority than the machine tool group with a lower temperature. Further, the refrigerated natural cold sources in the water tank are preferentially supplied to the machine tool group with a higher temperature, and the remaining natural cold sources are sequentially supplied to the machine tool groups with lower temperatures, further enabling multiple machine tool groups to exchange heat and cool down reasonably;

[0065] When the natural cold sources in the water tank cannot meet the cooling requirements of all machine tool groups, the machine tool groups with lower priorities are cooled through the natural cold sources in the cooling pool. At the same time, the temperature of the natural cold sources discharged by the heat exchange type water chiller in the machine tool groups with higher priorities must be higher than the temperature of the natural cold sources discharged by the heat exchange type water chiller in the machine tool groups with lower priorities. At this time, the natural cold sources discharged from the machine tool groups with lower priorities are preferentially placed into the cold source circulation water path and further transmitted back to the water tank through the cold source circulation water path for refrigeration by the cooling system, thereby reducing the energy consumption and time required for the cooling system to refrigerate, enabling the recycled natural cold sources in the water tank to quickly achieve the heat exchange and refrigeration effect, and further improving the overall working efficiency of the heat exchanger liquid temperature control system;

[0066] The natural cold sources discharged from the machine tool groups with higher priorities are preferentially discharged into the cooling pool for natural cooling, avoiding affecting the temperature of other natural cold sources in the cold source circulation water path and reducing the energy consumption required for the cooling system to refrigerate;

[0067] The above system operations are all automatically completed through the indoor integrated control system, and users can also perform manual operations through the indoor integrated control system, so that the heat exchanger liquid temperature control system can better meet the actual application requirements in the workshop.

[0068] A sedimentation tank is provided between the cold source circulation water path and the water tank, such that when the natural cold sources in the cold source circulation water path are recycled back into the water tank, they are first sedimented in the sedimentation tank. Further, when the natural cold sources exchange heat and refrigerate in the machine tool groups, due to heat absorption affecting the medium in the natural cold sources or absorbing impurities in the machine tool groups during the heat absorption process, the water quality of the natural cold sources will be poor, further resulting in poor heat exchange effect and low cooling efficiency. By sedimenting in the sedimentation tank, the impurities in the natural cold sources can be filtered out after sedimentation, further enabling the natural cold sources to effectively cool the machine tool groups.

[0069] Meanwhile, a cold source water quality detection system and a cold source water quality purification system are provided in the sedimentation tank, enabling the cold source water quality detection system to detect the water quality of the natural cold source stored in the sedimentation tank. When the water quality is qualified and can be discharged, the natural cold source can be re-discharged to the surface layer or the underground layer, allowing the natural cold source to enter the natural environment through natural circulation. Thus, during the process of extracting and utilizing the natural cold source by the heat exchanger liquid temperature control system, sustainable green production can be achieved without damaging the environment. And when the recycled natural cold source is unqualified, the cold source water quality purification system is used to purify the water quality of the natural cold source until the water quality is restored to the dischargeable level, and then the purified natural cold source is re-discharged.

[0070] The unpurified natural cold source in the sedimentation tank will be re-transferred to the water tank for the convenience of the subsequent continuous recycling by the heat exchanger liquid temperature control system. Moreover, multiple tank bodies are provided in the sedimentation tank. Since different batches of natural cold sources are purified, the heat exchanger liquid temperature control system can always maintain the water quality of the natural cold source during the continuous recycling process, thereby improving the heat exchange effect of the natural cold source.
