[0003] Liquid is a good coolant, but some workpieces cannot be cooled by machining fluid due to the material or subsequent process. In this case, high-pressure gas is usually used to spray the workpiece for cooling. However, high-pressure gas will raise the material fragments and dust generated by cutting to form dust mist, greatly increasing the risk of ignition. Utility Model Content

[0031] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0032] In the related art, spraying liquid around the inner wall of the processing chamber of the cutting machine tool to form a water curtain is an effective way to remove dust, which can make the dust flow to the liquid storage tank with the water to achieve the function of cleaning the processing chamber, which is conducive to reducing dust accumulation. At the same time, the liquid can cool the temperature in the processing chamber. However, the liquid may splash onto the workpiece while flowing, causing damage to the workpiece. As mentioned in the introduction, these materials cannot be exposed to liquids, which will affect the materials or subsequent processing.

[0033] Therefore, the embodiments of the present application provide a water curtain type protection device and machining equipment to effectively solve the aforementioned problems.

[0034] See also Figure 1 , Figure 1 A partial structural schematic diagram of a water curtain type protective device is shown. In one aspect, an embodiment of the present application discloses a water curtain type protective device, which is installed on machining equipment to clean the dust generated by the machining equipment and prevent liquid from splashing onto the workpiece in the machining equipment to achieve the purpose of protecting the workpiece. In addition, the embodiment of the present application uses liquid to take away the temperature in the machining chamber of the machining equipment to achieve cooling of the machining chamber.

[0035] For details, see Figure 2 , Figure 2 FIG. 1 shows a schematic diagram of the structure of a water curtain type protection device. Figure 2 As shown, the water curtain type protection device includes a frame 110, a guide structure 120 and a flushing pipe 130. The water curtain type protection device includes a frame 110, a guide structure 120 and a flushing pipe 130. The guide structure 120 is installed on the frame 110, and the flushing pipe 130 is installed on the frame 110 and is located on one side of the guide structure 120. The flushing pipe 130 is axially spaced with a plurality of water outlet holes 131 and each water outlet hole 131 is arranged toward the guide structure so that the liquid flowing out of the water outlet hole 131 can flow along the guide structure 120.

[0036] During operation, the liquid in the flushing pipe 130 flows to the guide structure 120 through the water outlet 131 and flows along the guide structure 120. In this way, the dust near the guide structure 120 can be removed by the liquid to reduce dust accumulation. Due to the setting of the guide structure 120, most or even all of the water flow 1 after the liquid flows out of the flushing pipe 130 flows along the surface of the guide structure 120. In this way, the situation where the liquid splashes onto the workpiece on the machining equipment during the flow process can be effectively reduced, which helps to reduce the probability of damage to the workpiece. In addition, the heat in the processing chamber is taken away by the liquid to achieve cooling, which is conducive to reducing the probability of dust combustion or even flash explosion in the processing chamber.

[0037] In some embodiments of the present application, Figure 2 As shown, the guide structure 120 is a mesh structure. Specifically, the mesh structure has pores, which can make the liquid spread as much as possible within the contact surface where the guide structure 120 is located, and can ensure the contact area between the dust and the guide structure 120, which helps to improve the carrying effect of the liquid on the dust, thereby improving the dust removal ability. In addition, the mesh structure can increase the heat exchange area, which helps to improve the cooling efficiency.

[0038] It is worth understanding that the pores in the mesh structure should not be too large to prevent the liquid from passing directly through the mesh structure and splashing onto the workpiece.

[0039] In this embodiment, the machining equipment includes a machining chamber, and a water curtain protection device is installed on the inner wall of the machining chamber. A workpiece is placed in the machining chamber, and the flushing pipe 130 is arranged on the side of the guide structure 120 close to the workpiece, that is, the flushing pipe 130 is located between the workpiece and the guide structure 120. In this way, the liquid flowing out of the water outlet 131 of the flushing pipe 130 flows out toward the side of the guide structure 130, that is, the liquid flows in the direction away from the workpiece, which helps to reduce the situation where the liquid splashes onto the workpiece. At the same time, after the liquid flows out of the flushing pipe 130, it mainly flows along the surface of the guide structure 120 close to the workpiece. In this way, the dust in the machining chamber can be fully contacted with the liquid, which helps to improve the dust cleaning effect. In addition, the heat in the machining chamber can also be directly taken away by the liquid, thereby improving the cooling effect.

[0040] In some embodiments of the present application, the mesh structure is made of flame-retardant material or metal material.

[0041] In a possible implementation, when the machining equipment is specifically a cutting machine, when cutting plastic or other flammable materials in the cutting machine without using liquid spray cooling, it is easy for the dust generated by the cutting to be ignited by the high temperature generated during the cutting and cause combustion or even flash explosion. Therefore, the material of the mesh structure is selected to be a flame retardant material or a metal material to prevent the mesh structure from burning.

[0042] In practical applications, the mesh structure can be made of metal, specifically, bronze or stainless steel.

[0043] Furthermore, the liquid in the flush pipe 130 can be a substance with fire extinguishing function to prevent or extinguish fire. For example, the liquid can be water.

[0044] In some other embodiments of the present application, the guide structure 120 includes a plurality of guide members spaced apart along the axial direction of the flushing pipe 130, the guide members are in the form of strips or lines, and each guide member extends in the vertical direction. Each guide member is provided corresponding to at least one water outlet 131. In this way, the liquid flowing out of the water outlet 131 can flow down along the guide member, and in this process, the dust in the machining equipment is carried away.

[0045] See also Figures 3 to 5 ,in, Figure 3 A schematic cross-sectional structure diagram of a water curtain type protection device in an embodiment is shown; Figure 4 for Figure 3 The schematic diagram of the partial enlarged structure of part A in the middle. Figure 5 FIG. 1 is a schematic diagram of the structure of a flushing pipe 130 in an embodiment.

[0046] like Figures 3 to 5 As shown, the water outlet hole 131 extends along the radial direction of the flushing pipe 130, and the axial direction of the water outlet hole 131 is set at an angle with the guide structure 120, wherein the angle is an acute angle. Specifically, the water outlet hole 131 is set toward one side of the guide structure 120 and downward, so that the liquid is facilitated to flow along the surface of the guide structure 120, reducing the situation where the liquid splashes onto the workpiece through the guide structure 120.

[0047] In some embodiments of the present application, see Figure 4 The frame 110 includes a first portion 111 and a second portion 112 which are spaced apart, and the flow guiding structure 120 is disposed between the first portion 111 and the second portion 112, and the flow guiding structure 120 is clamped by the first portion 111 and the second portion 112 to achieve fixation. In this way, when the flow guiding structure 120 is fixed, it is helpful to simplify the installation structure of the flow guiding structure 120, and at the same time, the flow guiding structure 120 can be better supported.

[0048] It is worth understanding that the guide structure 120 can also be installed and fixed on the frame 110 through other installation structures. For example, the guide structure 120 is fixed to the frame 110 through fasteners and a pressing plate. Specifically, the pressing plate is installed on the frame 110 through fasteners, and the guide structure 120 is clamped between the pressing plate and the frame 110.

[0049] In some embodiments of the present application, see Figure 2 The water curtain type also includes a water tank 150, a water pump 160 and a pipe 170. The water inlet of the water pump 160 is connected to the water tank 150, and the water outlet of the water pump 160 is connected to the flushing pipe 130 through the pipe 170. The water pump 160 is used to transport the liquid stored in the water tank 150 to the flushing pipe 130, and make the liquid flow from the water outlet 131 on the flushing pipe 130 to the guide structure 120. After the liquid flows out from the water outlet 131, it flows downward along the guide structure 120, and at the same time carries away the dust in contact with the guide structure 120, so as to achieve the purpose of dust removal. Since the flowing liquid continuously flows on the guide structure 120, the machining equipment can be cooled down, which is conducive to maintaining a stable ambient temperature in the machining equipment.

[0050] In some embodiments of the present application, see Figure 4 The water curtain type protection device further includes a pressing block 140, and the flushing pipe 130 is installed on the frame 110 through the pressing block 140. Specifically, the pressing block 140 is a U-shaped fixing member, and both ends of the pressing block 140 are fixedly connected to the frame 110. The pressing block 140 has a fixing hole matching the flushing pipe 130, and the flushing pipe 130 is inserted into the fixing hole.

[0051] Another aspect of the present application discloses a machining device, including the water curtain type protective device as described above. By setting the aforementioned water curtain type protective device on the machining device, the water curtain type protective device can be used to remove dust in the machining device, and at the same time, liquid splashing onto the workpiece on the machining device can be reduced. In addition, during the dust removal process of the water curtain type protective device, the flowing liquid can take away part of the heat generated in the machining device, thereby achieving the purpose of reducing the temperature in the machining device.

[0052] It should be pointed out that the machining equipment may specifically be a cutting machine tool, a drilling machine tool or other machining machine tools, which is not limited here.

[0053] In some embodiments of the present application, the machining equipment has a machining chamber, and the aforementioned water curtain type protection device is arranged at least one position around the inner wall of the machining chamber. It is worth understanding that multiple aforementioned water curtain type protection devices can also be arranged around the inner wall of the machining chamber, which is not limited here.

[0054] It should be pointed out that when installing the water curtain type protective device, the water curtain type protective device should be prevented from interfering with the normal operation of the machining equipment.

[0055] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
