Description

Technical Field

[0001] This invention belongs to the technical field of construction drilling equipment, and particularly relates to a shaping and cooling device for construction drilling. Background Technology

[0002] Construction drills are a type of twist drill and are widely used in the construction industry for drilling holes in hard materials such as concrete, brick walls, and marble. Construction drills are characterized by their wear resistance, high hardness, good toughness, and suitability for high-speed drilling. They are primarily made of cemented carbide and can be used with various tools such as hammer drills and electric drills. Construction drills have a straight shank shape with spiral flutes, allowing for deep drilling and a wide range of applications.

[0003] During the manufacturing process of construction drills, the workpiece and the drill bit are in a state of high-speed rotation for a long time. The contact friction between the two causes both the workpiece and the drill bit to heat up instantly. If the drill bit components are not cooled down in time, they are very likely to break or tilt, causing changes in their shape and affecting the machining accuracy.

[0004] The existing patent authorization number is CN213319171U, which discloses a shaping and cooling device for drilling bit processing. It reduces coolant waste by circulating coolant, saving energy and protecting the environment. By adjusting the opening of the flow valve, the flow rate of coolant is controlled, thereby controlling the cooling speed. This not only extends the service life of the drill bit and effectively improves drilling efficiency, but also ensures drilling accuracy, greatly improving work efficiency and drilling quality.

[0005] The above-mentioned fixed cooling equipment still has the following problems when it is in operation: (1) It only uses coolant to spray contact cooling, and its cooling application range is limited. For example, at certain times, when it is necessary to drill and process the construction work, and when it is necessary to accurately observe the processing status, the presence of coolant will obstruct the line of sight. Furthermore, when there is too much processing waste or the volume is small, the impurities mix with the coolant, which is not conducive to subsequent processing.

[0006] (2) Since the speed of the drill bit is changing, the above-mentioned use of regulating valve to adjust the speed and flow of water can, to some extent, match the changes in the speed of the drill bit. However, its timeliness and matching degree require real-time manual adjustment and control, which is difficult to achieve accurately. This will result in insufficient cooling of the construction drill bit or excessive output of coolant, causing waste.

[0007] Therefore, in view of the above-mentioned problems, this technical solution proposes a type of cooling device for construction drilling. Summary of the Invention

[0008] The purpose of this invention is to provide a shaping and cooling device for construction drilling, which aims to solve the following problems.

[0009] This invention is implemented as follows: a shaping and cooling device for construction drilling includes: a rotary power box and a processing operating table; the processing operating table is connected to one side of the output end of the rotary power box, a rotary power unit is installed inside the rotary power box, and a main drive shaft that moves through the box wall is connected to the output end of the rotary power unit. A rebar clamping and positioning fixture is installed at the outer end of the main drive shaft. The rebar clamping and positioning fixture is used to detachably install the rebar to be processed. A milling cutter device for milling the rebar to be processed is set on the side of the processing operating table away from the rotary power box. The rotary power unit drives the main drive shaft to control the spray nozzle on the rebar clamping and positioning fixture to rotate, and then cooperates with the milling cutter device to process the rebar to be processed into a construction drill bit. At the same time, the waste generated during processing falls onto the processing operating table under the action of gravity for centralized collection.

[0010] The air-cooled shaping mechanism is used to proportionally cool the rotating steel bars under processing. The air-cooled shaping mechanism includes an air outlet component located outside the rotating power box on one side of the steel bar to be processed. A fan box is connected to the side of the air outlet component facing the inside of the rotating power box. An air-cooling structure is set inside the fan box. The air-cooling structure generates flowing gas, which is then cooled by the air outlet component. The outer side of the air-cooling structure is rotatably connected to the rotating power unit through transmission component I. By rotatably connecting the air-cooling structure and the rotating power unit, the speed of the steel bar to be processed is kept positively correlated with the speed and volume of the air outlet component, thus realizing accurate and timely automated air-cooling shaping function when processing the steel bar.

[0011] The coolant-type shaping mechanism is used to perform proportional liquid cooling on the rotating steel bars. The coolant-type shaping mechanism includes a spraying component located on one side of the top of the steel bar. A pumping structure is connected to the side of the spraying component away from the steel bar. The top of the pumping structure is connected to a water tank installed on the top of the rotating power unit via a water pipe. The bottom of the pumping structure is rotatably connected to the rotating power unit via a transmission component II. By rotatably connecting the pumping structure to the rotating power unit, the speed of the steel bar's rotation and the speed and flow rate of the coolant sprayed by the spraying component toward the steel bar are positively correlated. That is, while the rotating power unit drives the main drive shaft to control the rotation of the steel bar, the pumping structure is synchronously driven by the transmission component II to spray the coolant in the water tank onto the steel bar in proportion through the spraying component, thereby achieving accurate and sufficient liquid cooling and shaping of the steel bar.

[0012] The pressurized waste liquid filtration mechanism is used to filter, cool, and reuse used coolant. It includes a pressurized filter box located inside a rotary power unit directly below transmission component II. The upper side wall of the pressurized filter box is connected to the bottom of one end of the processing platform via a waste liquid transfer pipe. Used coolant is transferred through the waste liquid transfer pipe to the pressurized filter box for filtration and purification. A return pipe is connected to one side of the bottom of the pressurized filter box, and the top of the return pipe is connected to a water tank. A heat exchanger is installed on the return pipe to cool the treated waste liquid. Through the action of the pressurized filter box, the return pipe, and the heat exchanger, the waste liquid is recycled and reused. The pressurized filter box contains a pressurization structure, the top of which is rotatably connected to the rotary power unit via transmission component II. Under the operation of the rotary power unit, the pressurization structure applies pressure to the inside of the pressurized filter box, thereby increasing the filtration efficiency of the waste liquid input into the pressurized filter box and accelerating the transfer speed of the waste liquid in the return pipe towards the water tank.

[0013] The adjustable lifting assembly consists of three sets, respectively located between the air-cooling structure and transmission component I, the pump-jet structure and transmission component II, and the pressurization structure and transmission component II. The adjustable lifting assembly is used for automated control of the rotational connection and separation between the air-cooling structure and transmission component I, the pump-jet structure and transmission component II, and the pressurization structure and transmission component II. Based on the cooling and shaping requirements of the steel bars to be processed, the method and quantity of rotational cooling and shaping, and the pressurization requirements during filtration, the equipment achieves controllability and operability during operation, ensuring the full and effective utilization of resources.

[0014] The present invention provides a shaping and cooling device for construction drilling, which uses an air-cooled shaping mechanism and a liquid-cooled shaping mechanism to cool the steel bars to be processed. The two mechanisms can operate independently or synchronously, which improves the applicability and operating efficiency of the shaping and cooling device during processing.

[0015] By adjusting the rotational connection between the air-cooled and liquid-cooled shaping mechanisms and the rotary power unit that drives the steel bars to be processed, the degree of air-cooling and liquid-cooling of the steel bars to be processed is kept consistent with the temperature rise state of the steel bars to be processed during rotation. This achieves sufficient and effective shaping and cooling capacity for the steel bars to be processed, and improves the effective conversion and utilization rate of kinetic energy, thus achieving an energy-saving and efficient operation mode.

[0016] By setting up a pressurized filter box and a pressurization structure, the waste liquid can be quickly and efficiently recycled, thus increasing the resource reuse rate of this equipment. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1-3 The diagram shows a structural diagram of a construction drilling and cooling device provided in an embodiment of the present invention, including: a rotary power box 10 and a processing operating table 11; the processing operating table 11 is connected to one side of the output end of the rotary power box 10, a rotary power unit is provided inside the rotary power box 10, and a main drive shaft 22 that moves through the box wall of the rotary power box 10 is connected to the output end of the rotary power unit. A rebar clamping and positioning fixture 13 is installed at the outer end of the main drive shaft 22. The rebar clamping and positioning fixture 13 is used to detachably install the rebar 12 to be processed. A milling cutter device (not shown in the figure) for milling the rebar 12 to be processed is provided on the side of the processing operating table 11 away from the rotary power box 10. The rotary power unit drives the main drive shaft 22 to control the spray nozzle 20 on the rebar clamping and positioning fixture 13 to rotate, and then cooperates with the milling cutter device to process the rebar 12 to be processed into a construction drill bit. At the same time, the waste generated during processing falls onto the processing operating table 11 under the action of gravity for centralized collection.

[0031] The air-cooled shaping mechanism is used to proportionally cool the steel bar 12 to be processed while it is rotating. The air-cooled shaping mechanism includes an air outlet component located outside the rotating power box 10 on one side of the steel bar 12 to be processed. A fan box 57 is connected to the side of the air outlet component facing the inside of the rotating power box 10. An air-cooling structure is set inside the fan box 57. The air-cooling structure generates flowing gas, which is then cooled by the air outlet component. The outer side of the air-cooling structure is rotatably connected to the rotating power unit through the transmission component I25. By rotatably connecting the air-cooling structure to the rotating power unit, the speed of the steel bar 12 to be processed is kept in a positive correlation with the speed and volume of the air outlet component, thus realizing accurate and timely automated air-cooling shaping function when processing the steel bar 12.

[0032] The coolant-type shaping mechanism is used to perform proportional liquid cooling on the steel bar 12 to be processed in a rotating state. The coolant-type shaping mechanism includes a spraying component set on one side of the top of the steel bar 12 to be processed. A pumping structure is connected to the side of the spraying component away from the steel bar 12 to be processed. A water tank 15 installed on the top of the rotating power box 10 is connected to the top of the pumping structure through a water pipe 32. The bottom of the pumping structure is rotatably connected to the rotating power unit through a transmission component II 26. By rotatably connecting the pumping structure to the rotating power unit, the speed of the steel bar 12 to be processed is positively correlated with the speed and flow rate of the coolant sprayed by the spraying component toward the steel bar 12 to be processed. That is, while the rotating power unit drives the main drive shaft 22 to control the rotation of the steel bar 12 to be processed, the pumping structure is synchronously driven to run under the transmission of the transmission component II 26, so that the coolant in the water tank 15 is sprayed onto the steel bar 12 to be processed in the same proportion through the spraying component, thereby achieving accurate and sufficient liquid cooling and shaping of the steel bar 12 to be processed.

[0033] A pressurized waste liquid filtration mechanism is used to filter and cool used coolant for reuse. The mechanism includes a pressurized filter box 34 located inside the rotating power box 10 directly below the transmission component II 26. The upper side wall of the pressurized filter box 34 is connected to the bottom of one end of the processing table 11 via a waste liquid transfer pipe 40. Used coolant is transferred through the waste liquid transfer pipe 40 to the pressurized filter box 34 for filtration and purification. A return pipe 39 is connected to one side of the bottom of the pressurized filter box 34. The top of the return pipe 39 is connected to the water tank 15. A heat exchanger 65 is provided to cool the treated waste liquid. The waste liquid is recycled and reused through the action of the pressurized filter box 34, the return pipe 39 and the heat exchanger 65. The pressurized filter box 34 is equipped with a pressurization structure. The top of the pressurization structure is rotatably connected to the rotary power unit through the transmission component II 26. Under the operation of the rotary power unit, the pressurization structure is driven to apply pressure to the inside of the pressurized filter box 34, thereby increasing the filtration efficiency of the waste liquid input into the pressurized filter box 34 and accelerating the transfer speed of the waste liquid in the return pipe 39 to the water tank 15.

[0034] The adjustable lifting assembly 27 has three sets, which are respectively located between the air-cooling structure and transmission component I 25, between the pumping structure and transmission component II 26, and between the pressurizing structure and transmission component II 26. The adjustable lifting assembly 27 is used to automatically control the rotational connection and separation between the air-cooling structure and transmission component I 25, between the pumping structure and transmission component II 26, and between the pressurizing structure and transmission component II 26. According to the cooling and shaping requirements of the steel bars 12 to be processed, the method and quantity of rotational cooling and shaping, as well as the pressurization requirements during filtration, the controllability and operability of the equipment during operation are realized, ensuring the full and effective utilization of resources.

[0035] The steel bar 12 to be processed is installed on the steel bar clamping and positioning fixture 13. Then, the milling cutter device and the rotary power unit are started to operate. The milling cutter device is controlled to mill the steel bar 12 according to the preset program. During the processing, according to the material of the steel bar 12 to be processed and the temperature change, the adjustable lifting component 27 is used to select the use of the air-cooled shaping mechanism and the coolant shaping mechanism to operate individually or synchronously. The rotating steel bar 12 to be processed is cooled and positioned by air drive and liquid cooling in the same proportion. This ensures that the steel bar 12 to be processed is cooled and shaped sufficiently and accurately, while reducing energy consumption and improving resource utilization. The cooling waste liquid used is filtered and reused through the pressurized filter box 34. At the same time, according to the filtration and purification intensity, the rotary power unit and the pressurized waste liquid filtration mechanism are selectively coordinated by the adjustable lifting component 27 to further improve the filtration and purification efficiency and waste liquid return efficiency. This realizes the coexistence and controllable setting of multiple cooling and shaping methods of this equipment, and the automated operation mode of accurately cooling and shaping the steel bar 12 to be processed.

[0036] In this embodiment of the invention, inclined waste material and waste liquid guide plates 23 are symmetrically arranged on both sides inside the processing table 11. The waste material and waste liquid guide plates 23 are used to concentrate and transfer the waste material generated during the processing of the steel bar 12 and the sprayed cooling waste liquid towards the middle of the processing table 11. A material collection channel 24 inclined towards the output end of the waste liquid transmission pipe 40 is provided at the bottom of the middle of the processing table 11. Under the action of the material collection channel 24, the waste liquid and waste are automatically transferred towards the bottom end of the processing table 11 again. A coarse filter screen 41 is provided at the connection between the waste liquid transmission pipe 40 and the processing table 11. The coarse filter screen 41 is used to perform initial filtration of large particulate impurities in the waste liquid. Then the waste liquid enters the waste liquid transmission pipe 40 and is transferred to the pressurized filter box 34 for further filtration and purification.

[0037] See Figure 10 The air outlet assembly includes an air outlet 16 installed on the outer wall of the rotating power box 10 corresponding to the outside of the fan box 57. An air duct 17 is detachably installed at the outer end of the air outlet 16. An air exhaust 18 is installed at the end of the air duct 17. The air duct 17 is made of carbon steel, which has sufficient hardness and can be manually adjusted according to the air outlet angle, so as to facilitate sufficient air cooling of the steel bar 12 to be processed.

[0038] The spraying assembly includes a drain pipe 33 connected to one side of the top of the pumping structure. The end of the drain pipe 33 is connected to a coolant output pipe 19. A spray nozzle 20 is installed at the end of the coolant output pipe 19. The coolant output pipe 19 is also made of carbon steel. By adjusting the placement of the spray nozzle 20, the steel bar 12 to be processed is fully sprayed with liquid cooling.

[0039] In one embodiment of the present invention, the milling cutter device is part of a milling machine and has an automatic omnidirectional movement function. It performs milling operations on the steel bar 12 to be processed, mounted on the steel bar clamping and positioning fixture 13, at various positions and angles, including front-to-back, left-to-right, up-down, etc. Since the technical problem to be solved by this technical solution is the cooling and shaping of the steel bar 12 during processing, it is not closely related to the milling cutter device and can be directly used with existing milling cutter devices. Therefore, it is not described in detail or shown in drawings, but this does not affect the completeness of the technical solution. As for the steel bar clamping and positioning fixture 13, it also adopts the structure of existing milling machines for clamping and positioning rod-shaped raw materials. Therefore, it will not be described in detail here.

[0040] In a preferred embodiment of the present invention, the rotary power unit includes a main power motor 14 installed on the inner side wall of the rotary power box 10. The output end of the main power motor 14 is connected to a main shaft 21. The end of the main shaft 21 is fixedly connected to the main drive shaft 22. That is, the main power motor 14 is started to drive the main shaft 21 to rotate, thereby driving the main drive shaft 22 to control the rotation of the steel bar 12 to be processed installed on the steel bar clamping and positioning fixture 13.

[0041] Transmission component II 26 includes a helical gear III 46 mounted on the main shaft 21. The upper and lower sides of the helical gear III 46 are engaged with the adjustable lifting assembly 27 in a lifting contact. Transmission component I 25 includes a helical gear I 44 mounted on the main shaft 21. The top side of the helical gear I 44 is engaged with the adjustable lifting assembly 27 in a lifting contact. That is, the helical gear III 46 and helical gear I 44 are driven to rotate by the adjustable lifting assembly 27 through the selective control of the lifting of the adjustable lifting assembly 27, thereby driving the operation of the pumping structure, the air-cooling structure and the pressurization structure.

[0042] Among them, see Figure 5The adjustable lifting assembly 27 at the meshing connection with helical gear III 46 includes a helical gear IV 47 that meshes perpendicularly with helical gear III 46. A telescopic rod 49 is fixedly installed on the middle of the side of helical gear IV 47 away from helical gear III 46. A sleeve 48 is fitted on the telescopic rod 49, and a lead screw 29 is installed at the end of the sleeve 48. A nut 28 is threaded onto the lead screw 29. A positioning key 50 is installed on the circumferential side wall of the telescopic rod 49. A positioning groove is opened on the inner wall of the sleeve 48 corresponding to the positioning key 50. The positioning key 50 moves up and down along the positioning groove, driving the helical gear when the main shaft 21 rotates. When Ⅲ46 rotates, it synchronously drives the helical gear Ⅳ47 to rotate. Then, under the constraint of the positioning key 50 and the positioning slide, the control sleeve 48 drives the lead screw 29 to rotate. The nut 28 is provided with a guide device to limit its rotation, thereby driving the nut 28 to move up and down along the lead screw 29 in a cyclic reciprocating motion. The upper side of the nut 28 is connected to the pumping structure, and the lower side of the nut 28 is connected to the pressurization structure. By using the reciprocating motion of the nut 28, the function of continuously outputting coolant from the pumping structure to the water tank 15 and continuously pressurizing the inside of the pressurized filter box 34 can be realized.

[0043] A positioning groove 52 is provided on the outer wall of the telescopic rod 49. A positioning slider 53 is slidably connected to the upper limit of the positioning groove 52. One end of the positioning slider 53 is connected to an electric telescopic rod 54 through a connecting rod. When the electric telescopic rod 54 is started, it drives the positioning slider 53 to move the telescopic rod 49 up and down, thereby controlling whether the helical gear IV 47 and helical gear III 46 connected to the telescopic rod 49 are engaged. In this way, the lifting and lowering of the adjustable lifting component 27 is controlled, which drives the start and stop of the pressurization structure and the pump injection structure.

[0044] Similarly, the adjustable lifting assembly 27 at the meshing connection with helical gear I 44 includes a helical gear II 45 that meshes with helical gear I 44. The top of helical gear II 45 is also equipped with a telescopic rod 49, a sleeve 48, a positioning key 50, a positioning groove, a positioning groove 52, and a positioning slider 53. Through the cooperation of these structures, the lifting contact meshing of helical gear II 45 and helical gear I 44 is achieved. Simultaneously, a helical gear V 58 is installed on the top of the sleeve 48, and a helical gear VI 59 is vertically meshed on one side of helical gear V 58. One side of helical gear VI 59 is connected to the air-cooling structure. That is, under the operation of the adjustable lifting assembly 27, the rotation of the main shaft 21 synchronously drives the air-cooling structure, realizing the function of synchronous change between the operation of the air-cooling structure and the operation of the main shaft 21.

[0045] Specifically, the electric telescopic rod 54 is installed and positioned inside the rotating power box 10 through structures such as fixed rods and fixed plates. The electric telescopic rod 54 is connected wirelessly or wiredly to provide terminal control for the operation of the staff.

[0046] The end of the lead screw 29 away from the helical gear IV 47 is rotatably mounted in the inner wall of the rotary power box 10 or in a nearby structural component via a bearing or other components.

[0047] As a preferred embodiment of the present invention, see [reference]. Figure 1 , Figure 2 , Figure 6 The pumping structure includes a piston cylinder mounted on one side of the top of the rotary power box 10. One side of the top of the piston cylinder is connected to the connecting water pipe 32, and the other side is connected to the drain pipe 33. A piston plate I 31 is slidably arranged inside the piston cylinder. A piston rod I 30 is connected to the bottom center of the piston plate I 31. The end of the piston rod I 30 is fixed to the nut 28 through a connecting rod. That is, under the cyclic lifting and lowering of the nut 28, the piston plate I 31 is driven to cyclically lift and lower along the inside of the piston cylinder. A water inlet valve plate 55 is magnetically attached to the lower inner side of the connection between the connecting water pipe 32 and the piston cylinder. A water outlet valve plate 56 is swayed to the upper outer side of the connection between the drain pipe 33 and the piston cylinder. As the cylinder descends, it generates a downward suction force. At this time, the inlet valve plate 55 swings outward to open, and the outlet valve plate 56 is sealed by suction. Then, with the connection of the water pipe 32, the coolant inside the water tank 15 is transferred to the piston cylinder on the upper side of the piston plate I 31. When the piston plate I 31 moves upward, it generates an upward thrust. At this time, the inlet valve plate 55 is sealed by pressure, and the outlet valve plate 56 is pushed upward. Then, the coolant on the upper side of the piston plate I 31 is discharged outward along the drain pipe 33. Then, it is sprayed and cooled on the steel bar 12 to be processed through the coolant output pipe 19 and the spray nozzle 20. The speed of the coolant output through the drain pipe 33 changes in the same direction as the rotation of the main shaft 21.

[0048] As a preferred embodiment of the present invention, see [reference]. Figure 1 , Figure 2 , Figure 4 , Figure 7The pressurization structure includes a piston plate II 36 movably connected inside the pressurized filter box 34. A piston rod II 35 is installed at the top center of the piston plate II 36. The top of the piston rod II 35 is connected to a nut 28 via a connecting rod. One side of the pressurized filter box 34 is connected to a waste liquid transmission pipe 40 via a waste liquid inlet pipe 43. A one-way water valve 42 is installed inside the waste liquid transmission pipe 40 to prevent backflow of gas and liquid. Driven by the nut 28, the piston plate II 36 is controlled to apply downward pressure and upward suction to the inside of the pressurized filter box 34. At the same time, a one-way air inlet is provided on one side wall of the pressurized filter box 34 for... The piston plate II 36 is used for air intake when it rises. Multiple multi-stage filter plates 37 are spaced apart on the lower side of the pressurized filter box 34. The multi-stage filter plates 37 are used to perform multi-stage filtration and purification treatment on the input waste liquid. A water inlet 38 is set in the middle of the bottom of the pressurized filter box 34. A one-way water valve 42 is also set inside the water inlet 38 to cause liquid backflow. That is, the piston plate II 36 pressurizes the waste liquid that has been filtered by the multi-stage filter plates 37 through the cyclic lifting and lowering, increasing the speed and purity of the liquid filtration by the multi-stage filter plates 37. The downward pressure of the piston plate II 36 changes in the same direction as the rotation of the main shaft 21.

[0049] As a preferred embodiment of the present invention, see section 2. Figure 8 , Figure 9 The air-cooled structure includes multiple sets of fan blades 60 arranged in a front-to-back, spaced manner inside the fan housing 57. A rotating shaft 61 is installed on one side of the fan blades 60. The rotating shafts 61 are rotatably connected by a transmission belt 63. The end of the rotating shaft 61 away from the fan blades 60 is rotatably mounted in the wall of the fan housing 57 via a guide rod 62. The end of the guide rod 62 located in the middle is connected to a main drive rod 64. The end of the main drive rod 64 is fixedly connected to a helical gear VI 59. That is, when the helical gear VI 59 rotates, it synchronously drives the main drive rod 64 to rotate. Then, under the transmission of the transmission belt 63, it synchronously drives the fan blades 60 to rotate. The outside of the fan blades 60 is connected to the air outlet 16 through an air supply pipe, thereby generating gas to cool the steel bar 12 to be processed. The rotation speed of the fan blades 60 changes in the same direction as the rotation speed of the main shaft 21.

[0050] The above embodiments of the present invention provide a shaping and cooling device for construction drilling. During operation, the steel bar 12 to be processed is installed on the steel bar clamping and positioning fixture 13. Then, the milling cutter device and the rotary power unit are started to operate, controlling the milling cutter device to mill the steel bar 12 according to a preset program. During the processing, according to the material and temperature changes of the steel bar 12, the adjustable lifting component 27 at the corresponding mechanism is operated to perform liquid cooling, air cooling, or both simultaneously on the steel bar 12. The waste generated from processing the steel bar 12 falls into the collection channel 24 in the processing operating table 11 under the action of gravity. In the process, the waste liquid used for liquid cooling also enters the collection channel 24, and then is transferred to the pressurized filter box 34 through the waste liquid transmission pipe 40 for filtration and purification. After being transferred through the return pipe 39 and cooled by the heat exchanger 65, it is transferred to the water tank 15 for use. When cooling the steel bar 12 to be processed, both the air-cooled shaping mechanism and the liquid-cooled shaping mechanism are driven by the rotary power unit, and the running speed is positively correlated with the speed at which the rotary power unit drives the steel bar 12 to be processed. This ensures that the cooling force of the steel bar 12 to be processed changes in the same direction as the milling speed of the steel bar 12 to be processed, that is, precise cooling and shaping are performed.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
