Description

Wire cutting machine device with constant temperature control system

The new model relates to a wire cutting machine, in particular to a wire cutting machine device with a constant temperature control system.

The wire cutting machine uses electric energy to generate high temperature to locally melt the workpiece to produce a predetermined contour, and is generally used for high-precision cutting. Since the cutting principle of the wire cutting machine is to melt the workpiece at a high temperature, a large amount of heat energy will be generated. If the heat is not dissipated in time, it will cause thermal deformation of the wire cutting machine and affect the cutting accuracy, so the environmental temperature is very high.

At present, the existing wire cutting machine is usually installed in a closed workshop, and the ambient temperature is controlled by the air conditioning system installed in the workshop. However, because workers need to enter and exit the plant frequently, it is easy to cause energy waste. Moreover, because of the large space of the plant, and sometimes it is necessary to install multiple wire cutting machines in one plant, even if the air conditioning system is used for the environment The temperature control is still unable to reliably guide the cold air to the wire cutting machine or the position of the wire cutting machines, resulting in poor cooling effect and poor control of the ambient temperature, and thus unable to effectively control the temperature around the wire cutting machine.

In this regard, the Republic of China Patent Certificate No. M442895 discloses an existing electric discharge machining constant temperature control system, which includes a closed case, an electric discharge machine arranged in the enclosed case, a refrigeration device arranged outside the enclosed case, and A radiator, a fan, a frequency conversion controller and a temperature sensor in the enclosed case.

The refrigeration device can provide cooled water to the radiator. When the temperature sensor detects that the temperature of the electrical discharge machine is too high, the inverter controller will control the fan to accelerate to increase the enclosed enclosure. The rate of heat exchange within. When the temperature sensor measures that the temperature of the electrical discharge machine is close to the target temperature, the inverter controller controls the fan to decelerate to reduce the heat exchange rate in the enclosed case.

Although the existing electric discharge machining constant temperature control system can control the temperature in the enclosed enclosure by adjusting the operating speed of the fan as described above, it still has the following shortcomings:

1. Since the radiator, the fan, the frequency conversion controller, and the temperature sensor are all arranged in the closed case, the volume inside the closed case is large, the cooling efficiency is not good, and it is easy to cause waste of energy.

2. The existing electric discharge machining constant temperature control system can only force the air and cold water in the enclosed enclosure to exchange heat by adjusting the fan's operating speed. Therefore, when the temperature in the enclosed enclosure is too low, the temperature rise cannot be adjusted immediately. The ability to control the ambient temperature is poor.

Therefore, the purpose of the present invention is to provide a wire cutting machine device with a constant temperature control system that can overcome at least one of the disadvantages of the prior art.

Therefore, the wire cutting machine device with a constant temperature control system of the present invention includes a shield unit, a wire cutting machine, and a temperature control unit.

The shield unit includes a shield body, a chamber defined by the shield body, an opening provided in the shield body and communicating with the chamber, and a shield door capable of opening and airtightly closing the opening.

The wire cutting machine is arranged in the chamber.

The temperature control unit includes a temperature sensor arranged in the chamber and capable of measuring the temperature of the wire cutting machine, a temperature control module arranged outside the cover, and a temperature control module arranged on the cover and connected to the temperature control module Group of heat exchange modules, and a control module connected to the temperature sensor and the temperature control module and arranged outside the cover by a signal.

The control module can control the temperature control module to generate a corresponding air flow according to the temperature of the wire cutting machine measured by the temperature sensor, and input the air flow to the heat exchange module to communicate with the chamber The air exchanges heat.

The effect of the present invention is that since the temperature control module and the control module are arranged outside the cover, and the heat exchange module is arranged on the cover, only the wire cutting machine and the temperature need to be arranged in the chamber. The sensor can effectively reduce the volume of the chamber, thereby improving the cooling efficiency and avoiding waste of energy.

1 to 4, an embodiment of the wire cutting machine device with a constant temperature control system of the present invention is suitable for processing a workpiece 1.

In this embodiment, the control module 45 is disposed in the input module 41, and the heat exchange module 44 is an evaporator, but it is not limited to this.

The input module 41 can be operated to input a predetermined temperature.

The temperature control module 43 has an air inlet pipe 431 connected to the heat exchange module 44, a heater 432, a cooler 433, a heating inverter 434 connected to the heater 432, and a heating converter 434 connected to the cooling module. The cooling inverters 435 and two of the heater 433 correspond to the gate switches 437 of the heater 432 and the cooler 433, respectively, and a three-way valve 436 connecting the air inlet pipe 431, the heater 432 and the cooler 433 .

The control module 45 can control the temperature control module 43 to generate a corresponding air flow according to the temperature of the wire cutting machine 3 measured by the temperature sensor 42 and input the air flow to the heat exchange module 44 It exchanges heat with the air in the chamber 22.

In this embodiment, the control module 45 can control the heater 432 and the cooler 433 according to the difference between the temperature of the wire cutting machine 3 measured by the temperature sensor 42 and the predetermined temperature. The corresponding one of the two generates a corresponding airflow, and adjusts the corresponding gate switch 437 so that the generated airflow passes through the three-way valve 436 and is input to the heat exchange module 44 through the air inlet pipe 431, and the control module 45 can also adjust the corresponding one of the heating frequency converter 434 and the cooling frequency converter 435 according to the difference between the temperature of the wire cutting machine 3 measured by the temperature sensor 42 and the predetermined temperature to Control the size of the airflow generated.

When a user is using the wire cutting machine device with a constant temperature control system, the user first needs to open the shield door 24 so that the workpiece 1 can be placed in the wire cutting machine 3 through the opening 23, and then close The shield door 24 can start processing operations.

In terms of temperature control, the user can input the predetermined temperature (for example, 25° C.) through the input module 41. During the processing, when the temperature of the wire cutting machine 3 measured by the temperature sensor 42 is greater than the predetermined temperature, the control module 45 will turn off the heater 432 and the gate corresponding to the heater 432 Switch 437, and turn on the cooler 433 and the gate switch 437 corresponding to the cooler 433, so that the airflow generated by the cooler 433 is input to the heat exchange module 44 through the three-way valve 436 and the air inlet pipe 431 to cool the The temperature of the air in the chamber 22.

When the temperature of the air in the chamber 22 decreases, so that the temperature of the wire cutting machine 3 measured by the temperature sensor 42 is lower than the predetermined temperature, the control module 45 turns off the cooler 433 and corresponds to The gate switch 437 of the cooler 433, and the heater 432 and the gate switch 437 corresponding to the heater 432 are turned on, so that the air flow generated by the heater 432 is input into the heat exchange module through the three-way valve 436 and the air inlet pipe 431 The group 44 heats the air temperature in the chamber 22.

Therefore, through the above-mentioned temperature control mechanism, the wire cutting machine 3 can be maintained at a predetermined temperature to achieve a constant temperature effect.

It should be noted that since the temperature control module 43 and the control module 45 are arranged outside the cover body 21, and the heat exchange module 44 is arranged on the cover body 21, only need to be arranged in the chamber 22 The wire cutting machine 3 and the temperature sensor 42 can effectively reduce the volume of the chamber 22, thereby improving the cooling efficiency and avoiding waste of energy.

It is worth mentioning that since the cutting principle of the wire cutting machine 3 is to melt the workpiece 1 at a high temperature, a large amount of heat energy is generated. In addition, in this embodiment, the heat exchange module 44 is disposed on the wire cutting machine 3, so the hot air generated by the wire cutting machine 3 during the processing process will enter the heat exchange module 44 upward due to thermal convection, and the air after heat exchange and cooling in the heat exchange module 44 will be It will flow downwards, so that internal heat convection can be formed, so there is no need to install a fan (not shown) to achieve good internal circulation, so energy consumption can be reduced.

In addition, since the shield door 24 can airtightly close the opening 23 when the shield door 24 is closed, the temperature outside the shield can be prevented from affecting the temperature in the chamber 22, and the thermal insulation layer 211 of the shield body 21 is It is made of heat-insulating material and is also provided with the sheet metal layer 212, which can prevent heat radiation conduction and reduce the influence of external temperature on the temperature in the chamber 22.

It is worth mentioning that, because the control module 45 can adjust the heating frequency converter 434 and the cooling frequency converter according to the difference between the temperature of the wire cutting machine 3 measured by the temperature sensor 42 and the predetermined temperature. The corresponding one of the device 435 is used to control the size of the generated airflow. Therefore, when the temperature of the wire cutting machine 3 measured by the temperature sensor 42 has a greater difference with the predetermined temperature, the The control module 45 can control to increase the airflow generated to accelerate the cooling or heating efficiency. When the temperature sensor 42 measures the temperature of the wire cutting machine 3 and the predetermined temperature, the smaller the difference, The control module 45 can control to reduce the generated air flow to avoid excessive heat exchange causing the temperature of the wire cutting machine 3 to rise or fall too fast and deviate from the predetermined temperature again.

It should be noted that in this embodiment, the heat exchange module 44 is an evaporator. However, in other implementations, the heat exchange module 44 may also be other forms of heat exchangers (for example: Shell-and-tube heat exchangers, etc.), as long as the heat exchange module 44 can supply the gas input of the heater 432 and the cooler 433 to exchange heat with the air in the chamber, the same purpose can be achieved.

In summary, the wire cutting machine device with a constant temperature control system of the present invention, because the temperature control module 43 and the control module 45 are arranged outside the cover body 21, and the heat exchange module 44 is arranged on the cover Therefore, only the wire cutting machine 3 and the temperature sensor 42 need to be arranged in the chamber 22, which can effectively reduce the volume of the chamber 22, thereby improving the cooling efficiency and avoiding the waste of energy. The purpose of this model.
