Description

Technical Field

[0001] The present invention belongs to the technical field of cutting devices, and particularly relates to a cutting device for desk metal parts and a using method thereof. Background Art

[0002] A desk is a piece of furniture used for reading, writing, and working, usually made of materials such as wood and metal. It is one of the indispensable pieces of furniture in places such as offices, schools, libraries, and homes. When processing a desk, it is necessary to cut metal parts (such as metal table legs). There are many cutting devices for metal parts on the market. For example, a Chinese patent with the publication number: CN219130920U discloses a metal part cutting device. Through the pressing of a pressing member, the metal part will not shake during cutting, ensuring that the end face of the cut metal part can remain flat. Through the design of a cleaning member, after the metal part is cut, the cutting table can be cleaned, keeping the cutting table clean and ensuring the flatness of the metal part cutting, which can meet the cutting requirements of metal parts to a certain extent.

[0003] However, since the processing of metal table legs is a batch and continuous process, this device lacks a cooling mechanism for the rotating disc cutter and the metal table legs, resulting in the rotating disc cutter being prone to overheating during long-term use. At the same time, after the metal table leg is cut, the surface temperature of the cut end is also very high, and the natural cooling time is very long, which will affect the processing of the next process of the metal table leg.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a cutting device for desk metal parts and a using method thereof.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide a cutting device for desk metal parts and a using method thereof, which can solve the problem that the rotating disc cutter and the metal table legs cannot be cooled during the processing of metal table legs.

[0007] To achieve the above purpose, the technical solution provided by a specific embodiment of the present invention is as follows: A cutting device for desk metal parts includes: a cutting table, a cutting mechanism, a pressing mechanism, an auxiliary fixed cooling mechanism, and a spray cooling mechanism; The cutting table surface is provided with a cutting groove; The cutting mechanism is installed on the cutting table and is disposed above the cutting groove; The pressing mechanism is installed on the tabletop of the cutting table and is arranged on one side of the cutting groove. The pressing mechanism is used to press the metal table leg; Both the auxiliary fixed cooling mechanism and the spray cooling mechanism are installed on the pressing mechanism. When the pressing mechanism presses the metal table leg, the auxiliary fixed cooling mechanism is used to better fit the metal table leg and at the same time cool the cutting end of the metal table leg. The spray cooling mechanism cooperates with the pressing action of the pressing mechanism and the cooling effect of the auxiliary fixed cooling mechanism to cool the cutting mechanism.

[0008] In one or more embodiments of the present invention, a pair of adjustment grooves are provided on the tabletop of the cutting table, and a quantitative plate is provided on the upper side of the cutting tabletop. The quantitative plate is slidably arranged in the pair of adjustment grooves, and the quantitative plate can slide in the adjustment grooves, so as to adjust the position of the quantitative plate, so as to determine the cutting length of the metal table leg and improve the cutting accuracy of the metal table leg.

[0009] In one or more embodiments of the present invention, the pressing mechanism includes a pair of columns. Both of the pair of columns are connected to the tabletop of the cutting table. The columns are used to install the base and the pressing member, so as to adjust the heights of the base and the pressing member, so as to use the pressing member to press the metal table leg and prevent the metal table leg from displacing during cutting, and thus ensure the cutting accuracy of the metal table leg. A guiding rod and a threaded rod are respectively installed in the pair of columns. The threaded rod is rotatably connected to the column. When the threaded rod rotates.

[0010] In one or more embodiments of the present invention, a base is installed between the pair of columns. The base is threadedly connected to the threaded rod and is slidably arranged on the guiding rod. The lower bottom surface of the base is fixedly connected with a pressing member. When the threaded rod rotates, the base can be lifted and lowered between the pair of columns under the action of the thread, so as to adjust the height of the pressing member, so as to use the pressing member to press the metal table leg.

[0011] In one or more embodiments of the present invention, the auxiliary fixed cooling mechanism includes a pressing flexible member. The pressing flexible member is installed at the lower port of the pressing member. When the metal table leg enters the opening of the pressing member, the metal table leg contacts the pressing flexible member and causes the pressing flexible member to deform. The deformed pressing flexible member is used to reversely fix the metal table leg to ensure the firmness of the metal table leg fixation; At the same time, since the pressing flexible member has elasticity, the pressing flexible member can also be applicable to metal table legs of various shapes, improving the overall applicable range; A pair of connecting bands are connected between the pressing flexible member and the inner top wall of the pressing member. A cooling cavity is formed among the pressing member, the pressing flexible member and the pair of connecting bands for temporarily storing the coolant, so as to use the coolant in the cooling cavity to cool the cutting end of the metal table leg and accelerate the cooling efficiency of the metal table leg after cutting, without affecting the subsequent processing.

[0012] In one or more embodiments of the present invention, a receiving cavity is provided in the pressing flexible member, and a plurality of first liquid outlet holes are provided at the top of the pressing flexible member. The receiving cavity is communicated with the cooling cavity through the first liquid outlet holes. The coolant in the storage tank will first enter the receiving cavity, which can not only cause the pressing flexible member to expand and use the expanded pressing flexible member to increase the firmness of the fixation of the metal table leg, but also make the coolant more likely to cool the metal table leg and improve the cooling efficiency of the metal table leg.

[0013] In one or more embodiments of the present invention, a storage tank is installed on the base. The storage tank is provided with a coolant and a water pump. The liquid outlet end of the water pump is connected to a straight pipe, and several conveying pipes are connected to the straight pipe. One end of the conveying pipe passes through the base and is arranged in the receiving cavity. When the water pump operates, the water pump extracts the coolant and transports the coolant to the receiving cavity through the straight pipe and the conveying pipe, so that the pressing flexible member expands, increasing the firmness of the fixation during the cutting of the metal table leg, avoiding displacement of the metal table leg, ensuring the cutting accuracy of the metal table leg, and at the same time, making the coolant closer to the metal table leg and improving the cooling efficiency of the metal table leg.

[0014] In one or more embodiments of the present invention, a return channel and an opening are provided in the base. The return channel is communicated with the outside through the opening. An outlet pipe is connected between the cooling cavity and the return channel. The coolant in the cooling cavity enters the return channel through the outlet pipe; A sealing plate is covered on the opening, and a return pipe is connected through the sealing plate. The return pipe is communicated with the storage tank. The coolant in the return channel then flows back to the storage tank through the return pipe.

[0015] In one or more embodiments of the present invention, the spray cooling mechanism includes a pair of connecting pipes. The pair of connecting pipes are symmetric with respect to the central axis of the base. One end of the connecting pipe is arranged in the receiving cavity, the other end of the connecting pipe passes through the pressing member, a control valve is installed on the connecting pipe, and a mist spray head is connected to the end of the connecting pipe outside the pressing member. The mist spray head corresponds to the cutting mechanism. When the control valve on the connecting pipe is opened, since the pressing flexible member is in an expanded state, the coolant in the receiving cavity is squeezed and sprayed out through the connecting pipe and the mist spray head, and is sprayed onto the rotating disc cutter of the cutting mechanism, avoiding the influence of the too high temperature of the rotating disc cutter on the cutting effect.

[0016] A method for using a cutting device for desk metal parts includes the following steps: S1. Adjust the position of the quantitative plate on the cutting table surface to determine the cutting length of the metal table leg; S2. Place the metal table leg on the cutting table surface and under the pressing member, and make one end of the metal table leg contact the quantitative plate; S3. Rotate the threaded rod to control the base and the pressing member to descend. When the metal table leg is engaged within the pressing member, the pressing flexible member is deformed by the extrusion of the metal table leg. The deformed pressing flexible member can better fit the surface of the metal table leg, thereby completing the fixation of the metal table leg. S4. Control the operation of the cutting mechanism and use the cutting mechanism to cut the metal table leg. S5. When the cutting mechanism cuts the metal table leg, operate the water pump. The water pump extracts the coolant and transports the coolant through the straight pipe and the delivery pipe to the accommodating cavity. Since the pressing flexible member is in close contact with the metal table leg, the coolant in the accommodating cavity can reduce the temperature of the cutting end of the metal table leg. At the same time, when the coolant enters the accommodating cavity, it will cause the pressing flexible member to expand. The expanded pressing flexible member can better squeeze the metal table leg, avoiding the displacement of the metal table leg during cutting and ensuring the cutting accuracy of the metal table leg. S6. The coolant in the accommodating cavity enters the cooling cavity through the first liquid outlet hole. As the coolant capacity in the cooling cavity gradually increases, the coolant in the cooling cavity enters the return channel through the liquid outlet pipe and returns to the storage tank through the return pipe. S7. When it is necessary to cool the cutting mechanism, open the control valve on the connecting pipe. Since the pressing flexible member is in an expanded state, part of the coolant in the accommodating cavity is sprayed onto the rotating disc cutter of the cutting mechanism through the connecting pipe and the atomizing nozzle, avoiding the overheating of the rotating disc cutter and affecting the cutting effect.

[0017] Compared with the prior art, a cutting device for a desk metal part and its usage method according to the present invention can cool the rotating disc cutter and the metal table leg, effectively avoiding the overheating problem that occurs when the rotating disc cutter is used for a long time, ensuring the working state of the rotating disc cutter, and at the same time, it can also accelerate the cooling speed of the cutting end of the metal table leg, without affecting the subsequent processing.

Detailed implementation mode

[0021] In order to enable the personnel in the technical field to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 16 shown, a cutting device for desk metal parts in an embodiment of the present invention includes a cutting table 1, a cutting mechanism 2, a pressing mechanism 3, an auxiliary fixed cooling mechanism 4, a spraying cooling mechanism 5 and a negative pressure suction mechanism 6.

[0023] Among them, a cutting groove 101 is provided on the table surface of the cutting table 1, and the cutting groove 101 corresponds to the rotating disc cutter of the cutting mechanism 2, so that the rotating disc cutter can better cut the metal table legs.

[0024] In addition, a waste liquid collecting groove is also provided in the cutting table 1, and the waste liquid collecting groove is arranged below the cutting groove 101. When the rotating disc cutter sprays and cools, the cooling liquid 404 on its surface can fall into the waste liquid collecting groove through the cutting groove 101 for collection.

[0025] Specifically, a pair of adjustment grooves 102 are provided on the tabletop of the cutting table 1. A quantitative plate 103 is provided above the tabletop of the cutting table 1, and the quantitative plate 103 is slidably arranged in the pair of adjustment grooves 102. The quantitative plate 103 can slide in the adjustment grooves 102, thereby adjusting the position of the quantitative plate 103 to determine the cutting length of the metal table leg and improving the cutting accuracy of the metal table leg.

[0026] As Figure 1 shown, the cutting mechanism 2 is installed on the cutting table 1 and is arranged above the cutting groove 101. The cutting mechanism 2 is used for cutting the metal table leg. The cutting mechanism 2 is a prior art and will not be elaborated in this application.

[0027] As Figures 1 to 16 shown, the pressing mechanism 3 is installed on the tabletop of the cutting table 1 and is arranged on one side of the cutting groove 101. The pressing mechanism 3 is used for pressing the metal table leg to prevent the metal table leg from moving during cutting, thereby ensuring the cutting accuracy of the metal table leg.

[0028] Among them, the pressing mechanism 3 includes a pair of columns 301. Both of the pair of columns 301 are connected to the tabletop of the cutting table 1. The columns 301 are used for installing the base 304 and the pressing member 305. A guiding rod 302 and a threaded rod 303 are respectively installed in the pair of columns 301. The threaded rod 303 is rotatably connected to the column 301. When the threaded rod 303 rotates, the height of the base 304 and the pressing member 305 can be adjusted to press the metal table leg by using the pressing member 305, preventing the metal table leg from displacing during cutting, and thereby ensuring the cutting accuracy of the metal table leg.

[0029] In addition, a base 304 is installed between the pair of columns 301. The base 304 is threadedly connected to the threaded rod 303 and is slidably arranged on the guiding rod 302. The lower bottom surface of the base 304 is fixedly connected with a pressing member 305. The shape of the pressing member 305 is as Figure 3 shown, and the metal table leg can enter the pressing member 305 to achieve the fixation of the metal table leg.

[0030] When the threaded rod 303 rotates, the base 304 can move up and down between the pair of columns 301 under the action of the thread, thereby adjusting the height of the pressing member 305 to press the metal table leg by using the pressing member 305 and preventing the metal table leg from displacing during cutting.

[0031] As Figures 1 to 16 shown, a return channel 3041 and an opening are provided in the base 304. The return channel 3041 is connected to the outside through the opening. A liquid outlet pipe is connected between the cooling cavity and the return channel 3041. The coolant 404 in the cooling cavity enters the return channel 3041 through the liquid outlet pipe.

[0032] Among them, the opening upper cover is provided with a sealing plate 3042. A return pipe 3043 is connected through the sealing plate 3042. The return pipe 3043 is communicated with the storage tank 403. The coolant 404 in the return channel 3041 then flows back into the storage tank 403 through the return pipe 3043.

[0033] In addition, an installation cavity 3044 is also provided in the base 304. The installation cavity 3044 is used to accommodate the first pulley 603. A maintenance cover is provided at the port of the installation cavity 3044, which is convenient for maintaining the installation cavity 3044.

[0034] Specifically, a plurality of fins 3045 are connected to the side wall of the return pipe 3043. A guide cover 3046 is provided outside the fins 3045. The guide cover 3046 can play a guiding role, enabling the gas to pass through the plurality of fins 3045. A plurality of air holes are provided at the top of the guide cover 3046.

[0035] Preferably, the return pipe 3043, the fins 3045 and the guide cover 3046 are all made of heat-conducting metal materials.

[0036] The gas sucked by the negative pressure suction mechanism 6 will enter the guide cover 3046, pass through the plurality of fins 3045, and finally be discharged through the air holes. When the coolant 404 flows back in the return pipe 3043, the temperature of the coolant 404 can be reduced, thereby avoiding the over-high temperature of the coolant 404 in the base 304, enabling the coolant 404 in the base 304 to quickly cool the cutting end of the metal table leg and the rotating disc cutter during the recycling process.

[0037] As Figures 1 to 16 shown, the auxiliary fixed cooling mechanism 4 and the spray cooling mechanism 5 are both installed on the pressing mechanism 3. When the pressing mechanism 3 presses the metal table leg, the auxiliary fixed cooling mechanism 4 can better fit the surface of the metal table leg, so as to improve the fixing effect of the pressing member 305 on the metal table leg. At the same time, it can also enable the pressing member 305 to fix metal table legs of various shapes, improving the overall applicable range of the pressing mechanism 3. When the coolant 404 flows in the pressing flexible member 401, the coolant 404 can also be used to cool the cutting end of the metal table leg, so as to accelerate the cooling efficiency of the metal table leg and will not affect the subsequent processing.

[0038] Among them, the auxiliary fixed cooling mechanism 4 includes a pressing flexible member 401. The pressing flexible member 401 is installed at the lower port of the pressing member 305, that is Figure 3 the position shown. When the metal table leg enters the opening of the pressing member 305, the metal table leg contacts the pressing flexible member 401 and causes the pressing flexible member 401 to deform. The deformed pressing flexible member 401 is used to fix the metal table leg in the reverse direction, ensuring the firmness of the metal table leg fixation and avoiding the displacement of the metal table leg during cutting, thereby ensuring the cutting accuracy of the metal table leg.

[0039] Meanwhile, since the pressing flexible member 401 has elasticity, the pressing flexible member 401 can also be applicable to the fixation of metal table legs of various shapes, improving the overall applicable range.

[0040] In addition, a receiving cavity 4011 is provided inside the pressing flexible member 401, and a plurality of first liquid outlet holes 4012 are provided at the top of the pressing flexible member 401. The receiving cavity 4011 is communicated with the cooling cavity through the first liquid outlet holes 4012. The coolant 404 in the storage tank 403 will first enter the receiving cavity 4011, which can cause the pressing flexible member 401 to expand, and the expanded pressing flexible member 401 is used to increase the firmness of the fixation of the metal table leg. At the same time, the coolant 404 in the receiving cavity 4011 is more likely to cool the metal table leg, improving the cooling efficiency of the cutting end of the metal table leg.

[0041] As Figures 14 to 16 shown, a pair of fixing strips 4013 are fixedly connected to the inner wall of the receiving cavity 4011. A plurality of mutually staggered hollow tubes 4014 and reinforcing strips 4015 are provided between the pair of fixing strips 4013. A plurality of uniformly distributed elastic bands 4016 are connected between the fixing strips 4013, the hollow tubes 4014 and the reinforcing strips 4015. The fixing strips 4013, the hollow tubes 4014, the reinforcing strips 4015 and the elastic bands 4016 can form a braided layer to enhance the overall strength of the pressing flexible member 401.

[0042] Meanwhile, when the pressing flexible member 401 is deformed by the extrusion of the metal table leg, since the fixing strip 4013 is fixed, part of the hollow tubes 4014 and the reinforcing strips 4015 are extruded and moved, and then the elastic bands 4016 are pulled and elongated. At this time, by using the elasticity of the elastic bands 4016 and the mutual cooperation of the hollow tubes 4014 and the reinforcing strips 4015, a reverse pressure is applied to the metal table leg to better fix the metal table leg and prevent the movement of the metal table leg, thereby ensuring the cutting accuracy of the metal table leg.

[0043] Among them, a plurality of delivery pipes 407 are respectively communicated with a plurality of hollow tubes 4014. One end of the hollow tube 4014 is provided with a plurality of second liquid outlet holes 4017, which are used to extend the flow time of the coolant 404 in the receiving cavity 4011 to ensure the cooling effect of the coolant 404 in the receiving cavity 4011 on the cutting end of the metal table leg. At the same time, it is used to increase the pressure of the coolant 404 in the receiving cavity 4011 entering the connecting pipe 501, so that the coolant 404 can be discharged through the atomizing nozzle 502 to generate atomized liquid, and the atomized liquid is used to cool the rotating disc cutter.

[0044] As Figures 1 to 16As shown, a pair of connecting bands 402 are connected between the pressing flexible member 401 and the inner top wall of the pressing member 305. A cooling cavity is formed among the pressing member 305, the pressing flexible member 401 and the pair of connecting bands 402 for temporarily storing the coolant 404, so as to use the coolant 404 in the cooling cavity to cool the cutting end of the metal table leg, accelerate the cooling efficiency of the metal table leg after cutting, and will not affect the subsequent processing. At the same time, the coolant 404 in the cooling cavity will press down the pressing flexible member 401 to further strengthen the fixing effect of the pressing flexible member 401 on the metal table leg, avoid the offset of the metal table leg during cutting, and ensure the cutting accuracy of the metal table leg.

[0045] Preferably, the pressing flexible member 401, the hollow tube 4014, the reinforcing strip 4015, the elastic band 4016 and the connecting band 402 are all made of high-strength rubber.

[0046] Among them, a storage tank 403 is installed on the base 304. The storage tank 403 is provided with a coolant 404 and a water pump 405. The liquid outlet end of the water pump 405 is connected with a straight pipe 406. A plurality of conveying pipes 407 are connected to the straight pipe 406. One end of the conveying pipe 407 passes through the base 304 and is arranged in the accommodating cavity 4011. When the water pump 405 operates, the water pump 405 extracts the coolant 404 and conveys the coolant 404 to the accommodating cavity 4011 through the straight pipe 406 and the conveying pipe 407, so that the pressing flexible member 401 expands, increasing the firmness of the fixation during the cutting of the metal table leg, avoiding the displacement of the metal table leg, ensuring the cutting accuracy of the metal table leg, and at the same time, making the coolant 404 closer to the metal table leg, improving the cooling efficiency of the metal table leg.

[0047] Preferably, the side wall of the storage tank 403 is provided with an observation plate and a replenishing pipe. The capacity of the coolant 404 in the storage tank 403 can be observed through the observation plate for timely replenishment through the replenishing pipe. The coolant 404 is water.

[0048] As Figures 1 to 16 shown, the spray cooling mechanism 5 cooperates with the pressing action of the pressing mechanism 3 and the cooling effect of the auxiliary fixed cooling mechanism 4 to cool the rotating disc cutter of the cutting mechanism 2.

[0049] Among them, the spray cooling mechanism 5 includes a pair of connecting pipes 501. The pair of connecting pipes 501 are symmetric with respect to the central axis of the base 304. One end of the connecting pipe 501 is arranged in the accommodation cavity 4011, and the other end of the connecting pipe 501 passes through the pressing member 305. A control valve is installed on the connecting pipe 501. One end of the connecting pipe 501 outside the pressing member 305 is connected with an atomizing nozzle 502, and the atomizing nozzle 502 corresponds to the cutting mechanism 2. When the control valve on the connecting pipe 501 is opened, since the pressing flexible member 401 is in an expanded state, the coolant 404 in the accommodation cavity 4011 is squeezed and will be sprayed out through the connecting pipe 501 and the atomizing nozzle 502, and sprayed onto the rotary disk cutter of the cutting mechanism 2, avoiding the rotary disk cutter from having too high a temperature and affecting the cutting effect.

[0050] As Figures 1 to 16 shown, a negative pressure suction mechanism 6 is installed in the base 304. The negative pressure suction mechanism 6 operates driven by the reflux coolant 404, and is used to suck the dust and metal particles generated during the cutting of the metal table leg, avoiding the dust and metal particles from polluting the environment and ensuring the working environment of the staff.

[0051] Among them, the negative pressure suction mechanism 6 includes a first rotating shaft 601. The first rotating shaft 601 is rotatably connected in the base 304. A first reinforcing member is connected between the first rotating shaft 601 and the bottom wall of the reflux channel 3041 for fixing the first rotating shaft 601. Both ends of the first rotating shaft 601 are respectively connected with a turbine 602 and a first belt pulley 603. The turbine 602 is arranged in the reflux channel 3041, and the first belt pulley 603 is arranged in the installation cavity 3044. When the coolant 404 flows in the reflux channel 3041, the coolant 404 can impact the turbine 602 and make the turbine 602 drive the first rotating shaft 601 and the first belt pulley 603 to rotate.

[0052] In addition, a negative pressure pipe 604 is installed on the outer top wall of the base 304. A second rotating shaft 605 is rotatably connected in the negative pressure pipe 604. A pair of second reinforcing members are connected between the second rotating shaft 605 and the bottom wall of the negative pressure pipe 604 for fixing the second rotating shaft 605.

[0053] Specifically, a negative pressure fan 606 and a second belt pulley 607 are connected to the second rotating shaft 605. A transmission belt 608 is connected between the second belt pulley 607 and the first belt pulley 603, and the transmission belt 608 passes through the negative pressure pipe 604. When the first belt pulley 603 rotates, the first belt pulley 603 drives the second belt pulley 607 and the second rotating shaft 605 to rotate through the transmission belt 608, and then can drive the negative pressure fan 606 to rotate, so that a negative pressure is generated at the port of the negative pressure pipe 604. When the rotary disk cutter cuts the metal table leg, the generated dust and metal particles will be sucked and enter the negative pressure pipe 604.

[0054] As Figures 1 to 16As shown, an air delivery pipe 609 is connected to the negative pressure pipe 604. The air delivery pipe 609 is arranged on the side of the negative pressure pipe 604 away from the cutting mechanism 2. One end of the air delivery pipe 609 is connected to a filter box 610, and at least a pair of filter meshes 611 are arranged in the filter box 610. The gas in the negative pressure pipe 604 enters the filter box 610 through the air delivery pipe 609, and passes through the guide pipe 612 into the flow guide cover 3046 under the filtration of multiple filter meshes 611. Under the guidance of the flow guide cover 3046, it passes through multiple fins 3045, which is used to cool the coolant 404 flowing in the return pipe 3043, avoiding the coolant 404 flowing back into the storage tank 403 having too high a temperature and ensuring the subsequent cooling effect of the coolant 404 on the cutting end of the metal table leg and the rotary disc cutter.

[0055] Among them, a guide pipe 612 is connected between the filter box 610 and the flow guide cover 3046. The filtered gas in the filter box 610 enters the flow guide cover 3046 through the guide pipe 612, which is used to cool the fins 3045 and the coolant 404 flowing in the return pipe 3043.

[0056] Preferably, a cleaning door is arranged on the side wall of the filter box 610, which is convenient for cleaning the soot and metal particles filtered by the filter mesh 611.

[0057] A method for using a cutting device for desk metal parts includes the following steps: S1. Adjust the position of the metering plate 103 on the table surface of the cutting table 1 to determine the cutting length of the metal table leg; S2. Place the metal table leg on the table surface of the cutting table 1 and under the pressing member 305, and make one end of the metal table leg contact the metering plate 103; S3. Rotate the threaded rod 303 to control the base 304 and the pressing member 305 to descend. When the metal table leg enters the pressing member 305, the pressing flexible member 401 is deformed by the extrusion of the metal table leg. The deformed pressing flexible member 401 can better fit the surface of the metal table leg, thereby completing the preliminary fixation of the metal table leg; S4. Control the cutting mechanism 2 to operate and use the cutting mechanism 2 to cut the metal table leg; S5. When the cutting mechanism 2 cuts the metal table leg, the water pump 405 is operated. The water pump 405 extracts the coolant 404 and transports the coolant 404 through the straight pipe 406 and the delivery pipe 407 into the hollow pipe 4014, and then enters the accommodation cavity 4011 through the second liquid outlet hole 4017. Since the pressing flexible member 401 is in close contact with the metal table leg, therefore, the coolant 404 in the accommodation cavity 4011 can reduce the temperature of the cutting end of the metal table leg. At the same time, when the coolant 404 enters the accommodation cavity 4011, it will cause the pressing flexible member 401 to expand. The expanded pressing flexible member 401 can better squeeze the metal table leg, avoid the displacement of the metal table leg during cutting, and ensure the cutting accuracy of the metal table leg; S6. The coolant 404 in the accommodation cavity 4011 enters the cooling cavity through the first liquid outlet hole 4012. As the volume of the coolant 404 in the cooling cavity gradually increases, the coolant 404 in the cooling cavity has a pressure effect on the pressing flexible member 401, so that the pressing flexible member 401 can better fix the metal table leg; S7. The coolant 404 in the cooling cavity enters the return channel 3041 through the liquid outlet pipe and flows in the return channel 3041. The coolant 404 flowing in the return channel 3041 will impact the turbine 602 and drive the first rotating shaft 601 and the first pulley 603 to rotate. The rotating first pulley 603 drives the second pulley 607 and the second rotating shaft 605 to rotate through the transmission belt 608, and further causes the negative pressure fan 606 to rotate. When the negative pressure fan 606 rotates, it can generate a negative pressure at the port of the negative pressure pipe 604, and use the negative pressure to suck the dust and metal particles generated when the rotary disc cutter cuts the metal table leg; S8. The coolant 404 in the return channel 3041 flows back to the storage tank 403 through the return pipe 3043. The gas in the negative pressure pipe 604 enters the filter box 610 through the air delivery pipe 609, passes through the guide pipe 612 through the filtration of multiple filter meshes 611, enters the diversion cover 3046, and passes through multiple fins 3045, and finally is discharged through the air holes. The gas in the diversion cover 3046 is used to cool the coolant 404 flowing in the return pipe 3043, avoid the temperature of the coolant 404 flowing back to the storage tank 403 from being too high, and ensure the cooling effect of the coolant 404 on the cutting end of the metal table leg and the rotary disc cutter subsequently; S9. When it is necessary to cool the cutting mechanism 2, the control valve on the connecting pipe 501 is opened. Since the pressing flexible member 401 is in an expanded state, part of the coolant 404 in the accommodation cavity 4011 is sprayed onto the rotary disc cutter of the cutting mechanism 2 through the connecting pipe 501 and the atomizing nozzle 502 for cooling the rotary disc cutter, so as to avoid the cutting effect being affected due to the too high temperature of the rotary disc cutter.

[0058] After the metal table leg is cut, stop the cutting mechanism 2 and the water pump 405, and control the base 304 and the pressing member 305 to rise, so that the pressing member 305 is disengaged from the extrusion of the metal table leg, facilitating the staff to remove the cut metal table leg. The residual coolant 404 in the accommodation cavity 4011, the cooling cavity and the return channel 3041 will not affect the subsequent cutting work of the metal table leg either.
