New description: [New technical field] This creation is about a kind of wire cutting, w,., ^, constant temperature control of enemy electric processing machine, two kinds of wire-cut electric discharge machine processing, the strange two-line cutting of the sink The processing temperature of the EDM machine and the set: degree reaction are minimized. ^ /里 [Prior Art] Please refer to the figure shown in the second figure as the structure of the current general line cutter electric discharge machine sink and water temperature circulation system. Schematic, as can be seen from the figure, the sink cooling device of the wire cutting machine EDM includes: a knife, a water tank (2 1 ), the water inlet is connected to the water outlet of the processing machine (20); a water tank (22) whose water outlet is connected to the water inlet of the sewage tank (2 1 ); a filter (2 3 ) connected to the water outlet of the sewage tank (2 1 ) and the clean water tank (2 2 ) At the water inlet, the water in the sewage tank (2 1 ) is filtered and then output to the clean water tank (2 2 ); the cooling machine (2 4 ), the water inlet and the water outlet are respectively connected with the clean water tank (2 2 ) The inlet and outlet connections are made in the above system processing tank (2 〇) When it is increased to a certain water level, the water in the processing tank (20) will flow into the sewage tank (2 1 ). At this time, the sewage in the sewage tank (2 1 ) will be filtered by the filter (2 3 ). Then input into the clean water tank (2 2 ), and the water in the clean water tank (2 2 ) passes through the cooling machine (2 4 ), and the cooling machine (2 4 ) will treat the water temperature according to the temperature of 4 M285409. The low temperature operation opening and closing temperature is built in. If the current water temperature is higher than the starting temperature, the purified water is cooled and then returned to the clean water tank (2 $ ). However, the current cooling equipment cannot ensure the water temperature change of the processing tank. The set temperature difference should not be too large', and often the machining accuracy is affected by the processing of the water (2 〇) water temperature rise, and it is found that the temperature setting value of the cold unit (2 4 ) is turned on and off. It will have a temperature difference of about 2~3 c from the set value. That is to say, when the setting temperature of the cooler (2 4) is set at the exit of the cold-keeping unit (24), it is set to ±15„c. The temperature error range is closed, so the cooler will stop running at 20.5 °c until the temperature rises to 23 5. When B enters L, it is only Will continue to start the operation, and such a flux error range is used to prevent the cooling machine from instantaneously stopping and instantaneously running at the critical point of 22. C, causing frequent power consumption during operation and opening and closing. As can be seen from the above description, the current line The cutting electric discharge machine and the cooling machine for water temperature have certain disadvantages, that is, when the clean water is supplied to the cooling machine for water temperature cooling, the cooling machine sends the cooling water back to the clean water tank. In the continuous processing discharge, the water temperature will continue to rise, so that the water temperature in the processing tank does not fall as soon as possible, and there is a situation in which the water temperature changes greatly, which in turn affects the processing precision of the processed product; After the low temperature is set, the cooling machine stops running until the water temperature of the clean water tank rises again to the high temperature set by the cooling machine, and then the operation is started. = The cooling machine determines that the water temperature is based on the water temperature flowing into the cooling machine. The water temperature in the processing tank is different from the temperature of the water flowing into the cooling machine, so that the current cooling device is difficult to control the water temperature of the processing tank. — Within a small range of values. Therefore, in order to avoid the large change of water temperature in the processing tank, the 5 M285409 machining accuracy is necessary to improve the design of the processing chamber thermostat. [New content] To this end, the main purpose of this creation is to provide a constant temperature control device for wire-cut EDM, so that the water flow of the cooler can be large, small, and freely free to react to the water temperature in the processing tank, and timely processing The tank provides cooling water so that the temperature of the water in the processing tank does not change too much, which affects the processing. The main technical means used to achieve the above purpose is to make the thermostatic control device of the wire-cut electrical discharge machine include: - a temperature sensor, which is placed in the processing tank to detect the water temperature of the processing tank, and the controller Connected to the output of the temperature sensor, which has a control routine to determine the temperature value of the temperature sensor output temperature, and then execute a control law calculation program to calculate the current temperature value. The corresponding speed value; and ^ then ~ water > quantity control element is set between the net sink inlet and the cooling machine outlet t, the control end is connected to the temperature controller's turn: ' The water quantity control element is controlled by the control thereof, and includes a frequency converter', an output connected to the temperature controller, and a rotational speed value thereof; and a pumping motor connected to the frequency conversion The inverter receives and controls the rotation speed of the phase motor, and the pumping motor is disposed between the clean water tank mouth and the pipeline of the cooler water outlet. M285409 The above water temperature control device is directly connected between the pipeline of the water tank inlet and the water outlet of the cooler, and a temperature sensor is arranged in the processing tank to reflect the water temperature in the processing tank. While controlling the water quantity control element to open the water (9) L, the size of the water is controlled according to the water temperature in the processing tank, and the amount of water flowing out of the cooling machine is controlled, and when the temperature is sensed, the water in the processing tank is sensed. When the temperature set by the temperature ratio is increased, the pumping motor will increase the rotation speed, and a large amount of water of the cooling machine is supplied to the clean water tank for cooling, thereby accelerating the return of the cooling water to the processing tank. In this way, it can compensate for the shortcoming that the cooling machine cannot quickly react to the change of the water temperature in the processing tank, causing the water temperature in the processing tank to change too much, which affects the processing precision. The creator aims to provide a water temperature control device for cooling equipment that provides cooling water quickly, that is, to add an ice water tank to the cooling machine, and to reduce the water in the clean water tank when the remaining ice water is 'starting to run. Water temperature.
