Description

Technical Field

[0001] The utility model relates to a CNC machining device, in particular to a CNC machining device involving waste gas utilization.

Background Art

[0002] A CNC machining device refers to a machining device that realizes automatic control by using a digital control system and is used for precision machining of materials such as metals, plastics, and woods. Since a large amount of oil mist is inevitably generated during the machining process of the CNC machining device, an oil mist collector is often configured inside the CNC machining device to separate and collect the oil mist inside the CNC machining device.

[0003] The existing oil mist collectors used in CNC machining devices often directly discharge the waste gas into the indoor air after extracting and separating the oil mist inside the machine case. The waste gas may be mixed with the smell of oil, which will affect the workers indoors. In addition, these waste gases are at a relatively high temperature, and the generated hot air will increase the load on the indoor air conditioner. Moreover, a cooling mechanism is separately configured inside the original CNC machining device. When the oil mist collector extracts the oil mist inside the machine case, it often takes away some cold air, which also causes waste of cold air.

[0004] Therefore, it is necessary to design a CNC machining device to overcome the above problems.

Content of the Utility Model

[0005] The creative purpose of the utility model is to provide a CNC machining device, which cools and recovers the waste gas discharged by the oil mist collector through a cooling mechanism, so that the waste gas will not only be discharged into the indoor air, but also become cold air to cool the machining tools inside the machine case.

[0011] Furthermore, the inside of the chassis includes a control area, and the control area is provided with control equipment for controlling the processing tools, and the cold air passes through the control area.

[0012] Furthermore, the cooling mechanism includes a box body and a condensation component housed in the box body.

[0017] Compared with the prior art, a CNC machining equipment provided by the present utility model has the following beneficial effects:

[0018] By arranging a cooling mechanism to cool and recycle the waste gas discharged from the oil mist collector, not only the waste gas will not be discharged into the indoor air, but also it can be turned into cold air and return to the chassis again to cool the processing tools inside the chassis.

Specific implementation manners

[0024] For better understanding of the purpose, structure, features, and effects of the present utility model, the present utility model will be further described below in conjunction with the drawings and specific implementation manners.

[0025] As Figure 1 shown, the present utility model provides a CNC machining equipment 100, which includes a chassis 1, an exhaust pipe 2, an intake pipe 3, an oil mist collector 4, and a cooling mechanism 5.

[0026] The chassis 1 includes a machining area 11 and a control area 12. A machining tool is provided in the machining area 11 for precision machining of materials such as metal, plastic, and wood. A control device is provided in the control area 12, and the control device includes circuit elements and a control panel for controlling the machining tool;

[0027] As Figure 2 shown, the oil mist collector 4 includes an air inlet 41, a first filter 42, an oil-gas separation device 43, a second filter 44, and an exhaust port 45. The air inlet 41 is arranged in the chassis 1, and a fan 533 is built in the air inlet 41 to absorb the oil mist and hot air in the chassis 1. The first filter 42 is a filter mesh, which is arranged behind the air inlet 41 to filter out the large particles contained in the absorbed gas. Subsequently, the filtered gas enters the oil-gas separation device 43. The oil-gas separation device 43 liquefies and collects the oil mist in the gas and recycles it. The second filter 44 is a filter cotton. The gas discharged after the oil-gas separation device 43 separates the oil mist will pass through the filter cotton, and the filter cotton will further filter out the fine dust or the remaining oil mist contained in the gas. The gas after being filtered again will reach the exhaust port 45 and enter the cooling mechanism 5 through the exhaust pipe 2 connected to one end of the exhaust port 45.

[0028] The oil mist collector 4 is located outside the chassis 1, and its bottom includes a first drain port 46. A collection bucket 6 is provided below the first drain port 46. When the oil-gas separation device 43 separates the oil mist, some water vapor often liquefies into water, and this water can flow into the collection bucket 6 through the first drain port 46. When the collection bucket 6 is full of water, the collection bucket 6 can be taken away at any time to pour out the water.

[0029] As Figure 1 and Figure 3 As shown, the cooling mechanism 5 includes an air inlet 51, a box body 52, a condensation component 53 located inside the box body 52, and an air outlet 54. The air inlet 51 is connected to the other end of the exhaust pipe 2, and the air outlet 54 is connected to one end of the intake pipe 3. The condensation component 53 cools the hot air entering from the air inlet 51 into cold air, and then sends the cold air into the intake pipe 3 through the air outlet 54. The other end of the intake pipe 3 is connected to the inside of the chassis 1, and then the cold air enters the chassis 1 through the intake pipe 3 to cool the control equipment and processing tools in the control area 12 and the processing area 11.

[0030] The box body 52 includes a first side surface 521 and a second side surface 522. The first side surface 521 and the second side surface 522 are adjacent or opposite. The air inlet 51 is located on the first side surface 521 of the box body 52, and the air outlet 54 is located on the second side surface 522 of the box body 52. The pipe orifice area of the exhaust pipe 2 is greater than one-third of the area of the first side surface 521, and the pipe orifice area of the intake pipe 3 is greater than one-third of the area of the second side surface 522. In this embodiment, the pipe orifice area of the exhaust pipe 2 is close to one-half of the area of the first side surface 521, and the pipe orifice area of the intake pipe 3 is close to one-half of the area of the second side surface 522. By setting large intake and exhaust pipes 3 and 2, the gas flow efficiency can be improved, and the volume of the gas in contact with the condensation component 53 can be increased, thereby improving the cooling efficiency of the condensation component 53. The box body 52 is provided on the top or side wall of the chassis 1, and the exhaust pipe 2 and the intake pipe 3 are bent and extended to connect the box body 52 with the oil mist collector 4 and the chassis 1, and can be used to fix the box body 52. The large pipe orifice areas of the exhaust pipe 2 and the intake pipe 3 also mean that the exhaust pipe 2 and the intake pipe 3 are large in volume, and their fixing effect on the box body 52 will be better. Further, considering that the exhaust pipe 2 and the intake pipe 3 are located outside the chassis 1, the length of the exhaust pipe 2 can be set to be less than the length of the intake pipe 3. Because cold air passes through the intake pipe 3, the intake pipe 3 can also provide a small amount of cold to the surrounding area, making the personnel working around the chassis 1 feel more comfortable.

[0031] The condensation assembly 53 includes a heat exchange tube 532, a water inlet 531, a water outlet 534, and a fan 533. Cold water enters from the water inlet 531, flows through the heat exchange tube 532, and then flows out from the water outlet 534. The fan 533 provides power to allow the gas entering from the air inlet 51 to pass through the heat exchange tube 532. Since cold water continuously flows through the heat exchange tube 532, the hot gas actually exchanges heat with the cold water flowing through the heat exchange tube 532. The two opposite side portions 535 of the condensation assembly 53 along its length direction are arranged at two diagonal corners of the box body 52. That is to say, the placement direction of the condensation assembly 53 is the same as the diagonal direction of the box body 52. This enables the length of the condensation assembly 53 to be greater than the length of the box body 52, thereby increasing the volume of the condensation assembly 53 and further increasing the heat dissipation efficiency of the condensation assembly 53.

[0032] In addition, considering that some water vapor will condense into water after the hot gas passes through the heat exchange tube 532, a second drain port 55 is provided at the bottom of the box body 52, and a drain pipe 56 is connected to the second drain port 55 to drain the condensed water into the collection bucket 6.

[0033] To keep the temperature of the processing area 11 constant, the cooling mechanism 5 further includes a temperature sensing element 57 and a flow control member 58. The temperature sensing element 57 is arranged in the processing area 11 to sense the temperature of the processing tool. The flow control member 58 is arranged at the water inlet 531 to control the flow rate of cold water. The specific process is that when the sensing element senses that the temperature of the working area is high, the flow rate of cold water is increased; when it senses that the temperature of the working area is low, the flow rate of cold water is decreased. Since the hot gas actually exchanges heat with the cold water flowing through the heat exchange tube 532, controlling the flow rate of cold water can control the temperature of the cold air, thereby affecting the temperature of the processing area 11.

[0034] The above detailed description is only for the description of the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of this creation specification and drawings are included in the patent scope of this creation.
