After entering the jet main pipe 401, the air can enter the inside of the plurality of jet branch pipes 402 respectively, and then be sprayed out from the plurality of first spray holes 403 on the side walls of the plurality of jet branch pipes 402, so as to act on the upper area of ​​the mesh plate 302, so as to blow away the coolant remaining on the surface of the workpiece above the mesh plate 302, thereby realizing automatic cleaning of the coolant on the workpiece surface.

[0040] See also Figure 2 and Figure 4In one embodiment, the piston component 501 includes a piston sleeve 5011 and a first piston block 5012, the piston sleeve 5011 is fixedly arranged at the bottom of the center plate 301, the lower end of the jet manifold 401 passes through the center plate 301 and is connected to the inner cavity of the piston sleeve 5011, the first piston block 5012 is movably arranged inside the piston sleeve 5011, the power component 502 includes a threaded sleeve 5021, a screw 5022, a cylinder 5023 and a second piston block 5024, the cylinder 5023 is fixedly installed at the bottom of the inner side of the liquid storage tank 10, and the inner wall of the cylinder 5023 is provided with Spiral groove 5027, the second piston block 5024 is movably arranged inside the cylinder 5023, the side wall of the second piston block 5024 is fixedly provided with a protrusion 5026, the protrusion 5026 extends into the spiral groove 5027, the lower end of the piston sleeve 5011 extends into the cylinder 5023 and is connected to the second piston block 5024, the threaded sleeve 5021 is fixedly arranged at the bottom of the first piston block 5012, one end of the screw rod 5022 is fixedly connected to the upper part of the second piston block 5024, and the other end extends into the threaded sleeve 5021 and is threadably matched with the threaded sleeve 5021.

[0041] When the driving assembly 20 drives the ring plate 303, the holding mesh plate 302 and the center plate 301 to move downward as a whole, the center plate 301 can drive the piston sleeve 5011, the first piston block 5012, the threaded sleeve 5021, the screw 5022 and the second piston block 5024 to move downward as a whole. When the second piston block 5024 moves downward, the protrusion 5026 adaptively slides downward along the spiral groove 5027, and the spiral groove 5027 pushes the protrusion 5026 to drive the second piston block 5024 to rotate, thereby The screw rod 5022 is driven to rotate. When the screw rod 5022 rotates, the screw rod 5021 and the first piston block 5012 are driven to move downward along the inside of the piston sleeve 5011 through the threaded cooperation with the thread of the threaded sleeve 5021. When the first piston block 5012 moves downward, the outside air is drawn from the first spray hole 403 into the inside of the jet branch pipe 402, and then drawn from the jet branch pipe 402 into the inside of the jet main pipe 401, so as to achieve the purpose of exhausting air. After the workpiece on the upper part of the mesh plate 302 is cooled, the driving assembly 20 is driven The movable ring plate 303, the holding mesh plate 302 and the center plate 301 move upward as a whole, and at this time the center plate 301 drives the piston sleeve 5011, the first piston block 5012, the threaded sleeve 5021, the screw 5022 and the second piston block 5024 to move upward as a whole. When the second piston block 5024 moves upward, the protrusion 5026 adaptively slides upward along the spiral groove 5027, and the spiral groove 5027 pushes the protrusion 5026 to drive the second piston block 5024 to rotate in the opposite direction, thereby driving the screw 5022 to rotate in the opposite direction. 022 rotates in the opposite direction. When the screw rod 5022 rotates in the opposite direction, it cooperates with the reverse thread of the threaded sleeve 5021 to drive the threaded sleeve 5021 and the first piston block 5012 to move upward along the inside of the piston sleeve 5011. When the first piston block 5012 moves upward, the air inside the jet main pipe 401 is reversely pressed and sent to the inside of the jet branch pipe 402, and then sprayed from the first spray hole 403 to the upper area of ​​the screen plate 302, so as to blow away the coolant remaining on the surface of the workpiece, thereby realizing automatic cleaning of the coolant on the surface of the workpiece.

[0042] See also Figure 2 In one embodiment, a vertically distributed guide rail 5013 is fixedly provided on the inner wall of the piston sleeve 5011 , and a guide rail groove (not shown in the figure) adapted to the guide rail 5013 is opened on the side wall of the first piston block 5012 .

[0043] The side wall of the first piston block 5012 is slidably matched with the guide rail 5013 through the guide rail groove, so that when the screw rod 5022 rotates, it can smoothly and steadily drive the first piston block 5012 to move along the inside of the piston sleeve 5011 through the threaded match with the threaded sleeve 5021, thereby realizing the air extraction and compression actions.

[0044] See also Figure 2In one embodiment, the jet branch pipe 402 is in an arc-shaped structure, and a second jet hole 404 is provided at one end of the jet branch pipe 402 away from the jet main pipe 401. The jet main pipe 401 is rotatably connected to the piston sleeve 5011 via a rotary joint (not shown in the figure).

[0045] When the first piston block 5012 moves upward along the piston sleeve 5011 to pressurize the air in the jet main pipe 401 to the jet branch pipe 402, a part of the air is ejected through the first spray holes 403 and acts on the workpiece on the upper part of the mesh plate 302 to blow away the coolant remaining on the workpiece, and another part of the air is ejected through the second spray holes 404. At this time, since the jet main pipe 401 and the piston sleeve 5011 are rotatably connected by a rotary joint, and the jet branch pipe 402 is an arc-shaped structure, when a part of the air When spraying through the second spray hole 404, the reaction force applied by the air flow to the jet branch pipe 402 deviates from the axial direction of the jet main pipe 401, thereby pushing the jet main pipe 401 to rotate compared to the piston sleeve 5011. When the jet main pipe 401 rotates, it drives the several jet branch pipes 402 to rotate, so that the air sprayed through the several first spray holes 403 on the side walls of the several jet branch pipes 402 is in a rotating state, and then the workpiece on the upper part of the mesh plate 302 is swept and blown, thereby providing a blowing effect of residual coolant on the surface of the workpiece.

[0046] See also Figure 2 In one embodiment, a plurality of through holes 5025 are provided at the lower portion of the side wall of the column 5023 .

[0047] When the holding mesh plate 302 moves downward to bring the workpiece into the coolant inside the liquid storage tank 10, since the second piston block 5024 moves downward synchronously along the inside of the column 5023, the second piston block 5024 can press part of the coolant inside the column 5023 out from the plurality of through holes 5025. After being pressed out from the through holes 5025, this part of the coolant can have an impact effect on the coolant inside the liquid storage tank 10, thereby stirring the coolant inside the liquid storage tank 10. The stirred coolant can more fully contact the workpiece on the upper part of the holding mesh plate 302, thereby improving the cooling effect of the workpiece.

[0048] In the embodiment of the present invention, when the workpiece is quenched, the heated workpiece can be placed on the upper part of the holding component 30, and then the driving component 20 is used to drive the holding component 30 to move downward. When the holding component 30 moves downward, it drives the workpiece on its upper part to move into the liquid storage tank 10, and the workpiece is immersed in the coolant in the liquid storage tank 10 to achieve the cooling treatment of the workpiece. After the workpiece is cooled, the driving component 20 drives the holding component 30 to move upward, and when the holding component 30 moves upward, it drives the workpiece upward, so that the workpiece is removed from the coolant, and the staff picks up the cooled workpiece. When the holding component 30 drives the workpiece to move upward, air is supplied to the inside of the jet component 40 through the air supply component 50, and the air is sprayed to the upper area of ​​the holding component 30 through the jet component 40, thereby blowing away the coolant remaining on the surface of the workpiece, thereby realizing automatic cleaning of the coolant on the surface of the workpiece. Compared with the prior art, it can automatically clean the coolant remaining on the surface of the workpiece after quenching and cooling, thereby preventing the workpiece from carrying the coolant into subsequent processing links, avoiding the residual coolant from affecting the subsequent processing of the workpiece, thereby improving the processing quality of the workpiece.
