Description

Technical Field

[0001] The utility model relates to the technical field of purging devices, in particular to a purging device used for a numerically controlled lathe. Background Art

[0002] As an important equipment in the field of modern processing, CNC lathes are widely used in the cutting of graphite and other materials. In the process of graphite cutting, due to the brittleness and fragility of graphite, a large amount of graphite dust will be generated during cutting. This dust will not only pollute the working environment, but also adhere to the surface of the tool and the workpiece, affecting the processing quality and the service life of the tool. Therefore, the traditional treatment method often uses a fan or air pump to blow air to achieve the blowing of graphite dust and the cooling of the tool;

[0003] However, during the purge process, the gas blown by the traditional purge device is often natural wind. Although it has a cooling effect on the tool body, the cooling effect is not good, resulting in increased wear of the tool during a long period of cutting due to the poor cooling effect, thereby reducing the service life of the tool. Therefore, a purge device for a CNC lathe is proposed to address the above situation. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the gas blown is often natural wind, which has a cooling effect on the tool body, but the cooling effect is not good, resulting in increased wear of the tool during a long cutting process due to the poor cooling effect. A blowing device for a CNC lathe is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A purging device for a numerically controlled lathe comprises the numerically controlled lathe. The numerically controlled lathe is provided with a box body, and the box body is provided with a fan.

[0007] A cooling component is also provided in the box, which includes a cooling box connected to the fan outlet pipe. The cooling box has a cavity. Four partitions are staggered from top to bottom on both sides of the cavity. Two adjacent partitions and the inner surface of the cavity together form a flow channel and an air supply channel. The flow channel is connected to the air supply channel.

[0008] The outer surface of the cooling box is provided with two rows of semiconductor cooling plates communicating with the cavity, each row of semiconductor cooling plates has four pieces, and each semiconductor cooling plate cooperates with the flow channel on the same horizontal plane.

[0009] The cooling box is provided with a storage groove, in which a collection box is slidably matched, and an exhaust assembly is provided on the top of the cooling box. One end of the exhaust assembly away from the cooling box is arranged on a CNC lathe.

[0010] Preferably, four rectangular grooves for installing semiconductor cooling sheets are respectively formed on two corresponding side surfaces of the outside of the cooling box, and the size of the rectangular grooves is adapted to the semiconductor cooling sheets.

[0011] Preferably, a plurality of water leakage holes connected to the receiving grooves are provided on the bottom surface of the cavity, and a sealing gasket is provided on the outer surface of the collecting box.

[0012] Preferably, a drying chamber is provided on the top of the cooling box, a receiving groove is provided on the drying chamber, and a cover plate covering the receiving groove is hinged on the drying chamber.

[0013] Preferably, a desiccant bag is arranged in the containing tank, and a conduit communicating with the cavity is arranged at the bottom of the drying chamber, and one end of the conduit away from the drying chamber is communicated with the containing tank.

[0014] Preferably, the exhaust assembly includes a delivery pipe connected to the drying chamber, and a shunt pipe installed on the CNC lathe is provided at one end of the delivery pipe, and a plurality of nozzles are provided on the shunt pipe.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model can pre-cool the gas blown onto the cutter body through the structural design of the cooling box, cavity, partition and semiconductor refrigeration sheet, and blow it to the cutter body after cooling, which can further reduce the temperature of the cutter, extend the service life of the cutter, and improve the processing quality and efficiency. In addition, the staggered layered arrangement of the partitions can perform multi-layer cooling treatment on the air, which significantly improves the cooling quality. Through the layered design of the partitions, the cooling air can gradually reduce the temperature when flowing through each layer, so that the gas finally blown to the cutter body has a lower temperature, thereby further improving the cooling effect.

[0017] 2. The utility model can collect water droplets generated by the cooling air in the cavity through the structural design of the storage groove and the collection box, so as to avoid the influence of water droplet aggregation and leakage on the operation of other electrical equipment in the device. At the same time, the inclination design of the partition surface helps to guide the generated water droplets, further improving the collection effect of water droplets.

In order to facilitate maintenance, a box door is provided on the cooling box 5. The cooling box 5 has a cavity 501. Four partitions 6 are staggered on both sides of the cavity 501 from top to bottom. The top of the partition 6 has an inclination angle to facilitate the diversion of the generated water droplets. Two adjacent partitions 6 and the inner surface of the cavity 501 together form a flow channel 7 and an air supply channel 701. The flow channel 7 is connected to the air supply channel 701.

[0026] The outer surface of the cooling box 5 is provided with two rows of semiconductor cooling sheets 8 connected to the cavity 501.

At the same time, turn on the switches of the two rows of semiconductor cooling sheets 8, and energize the two rows of semiconductor cooling sheets 8. The semiconductor cooling sheets 8 work to cool the air entering the cooling box 5. Since the four partitions 6 cooperate with the cavity 501 from top to bottom to form a plurality of flow channels 7, the air at the bottom passes through the corresponding air supply channels 701 one by one to transport the cooled air from the flow channel 7 to the top of the cavity 501.

Finally, the cooled air is transported to the drying bin 9 through a conduit. The drying bin 9 has a desiccant bag, and the desiccant bag contains a desiccant, which is used to dry the exhausted cold air to avoid the graphite powder adhering to the equipment due to the blowing of humid air, causing collection difficulties. Finally, the dried gas is transported to the exhaust assembly 10 and discharged through several nozzles to achieve the blowing of graphite powder and the cooling of the tool. A conduit connected to the cavity 501 is arranged at the bottom of the drying bin 9, and the end of the conduit away from the drying bin 9 is connected to the receiving tank.
