Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, specifically to a standardized cooling device and cooling method for steel plate drilling. Background Technology

[0002] Plate drills are precision cutting tools (or drilled plate workpieces, adapted to the application scenario) specifically designed for drilling into metal materials such as steel plates and structural steel. Due to their high hardness, wear resistance, and high drilling efficiency, they are widely used in machinery manufacturing, steel structure installation, automotive parts production, and shipbuilding. During actual processing, plate drills must withstand the intense friction generated by high-speed rotation and metal cutting, leading to a rapid increase in their own temperature (or internal stress generated in the drilled plate workpiece due to hot processing). If cooling and shaping are not performed in time, the high temperature will cause wear on the cutting edge, a decrease in hardness, a shortened service life, and even tool deformation, affecting drilling accuracy. Meanwhile, the drilled plate workpiece may warp or crack due to unreleased internal stress, reducing the workpiece's quality. Therefore, cooling and shaping is an indispensable and crucial step in the entire plate drill processing process; its cooling effect directly determines the performance, lifespan, and finished product yield of the plate drill. Existing cooling equipment often employs static designs for its support structure (such as placement baskets and mounting frames). Steel plate drills are stacked within the support device, meaning only the surface of the workpiece can fully contact the cooling medium during cooling. Cooling dead zones easily form at the stacking points and tool gaps, leading to excessively large localized temperature differences on the workpiece. This uneven cooling can cause internal stress in the steel plate drill (or the processed steel plate workpiece), resulting in cutting edge deformation, workpiece warping, or uneven metal structure, reducing tool hardness and wear resistance, and affecting subsequent drilling accuracy. After the steel plate drill cools, a large amount of cooling medium (such as water or special coolant) remains on its surface. Existing equipment lacks an efficient drying structure and mostly relies on natural dripping or manual wiping. Natural dripping is time-consuming and affects the production cycle; manual wiping can easily scratch the cutting edge of the steel plate drill, or cause the residual medium to corrode the tool due to incomplete wiping, reducing the product qualification rate and service life.

[0012] Preferably, both the first motor and the second motor are servo motors.

[0013] The present invention further provides a shaping and cooling method for drilling steel plates, comprising the following steps: Step 1: Initial state, the carrier box is located above the unloading platform. At this time, the hinge cover is located on the upper part of the carrier box. Open the hinge cover, load the material into the carrier box, and then close the hinge cover. Step 2: Start the second motor via the control terminal, and the feeding component begins to work: The second motor drives the second rotating shaft to rotate, which in turn drives the second bevel gear to mesh with the two sets of first bevel gears, thereby synchronously driving the screws in the sliding frames on both sides to rotate; The slide plate moves with the screws through the threaded connection, driving the upper bearing component to move horizontally to directly above the cooling box, completing the positioning of the cooling station; Step 3: Start the lifting device to drive the lifting plate to descend, so that the carrier box and the internal workpiece are completely immersed in the cooling medium of the cooling box; start the first motor, and the rotating parts begin to work: the first motor drives the first gear and the second gear to mesh, driving the first shaft to rotate. The third gears at both ends of the first shaft drive the fourth gear on the rotating shaft to rotate through the chain, thereby driving the carrier box to rotate slowly around the rotating shaft; the workpiece rotates with the carrier box in the cooling medium, and the cooling medium fully contacts the surface of the workpiece through the hollow holes on the side wall of the carrier box to achieve uniform cooling and shaping, avoiding workpiece deformation caused by local temperature differences. The cooling time is set according to the workpiece specifications. Step 4: After the cooling time is reached, start the lifting device to raise the carrier box and remove it from the cooling medium; start the feeding component again to drive the slide plate to move horizontally above the unloading platform; start the drying component: the fan delivers the heated air in the hot air box to the output head through the connecting pipe, and at the same time, start the pusher on the auxiliary frame to push the push plate so that the output head fits against the air inlet on the rotating shaft; the carrier box continues to rotate slowly, and the hot air enters the inside of the carrier box through the air inlet, forming an airflow circulation with the hollow holes in the side wall, quickly drying the cooling medium remaining on the surface of the workpiece; Step 5: After drying is complete, unload the material from the carrier box.

[0014] Compared with the prior art, the present invention provides a shaping and cooling device and a cooling method for drilling steel plates, which has the following beneficial effects: This fixed-type cooling equipment and its cooling method for steel plate drilling involves a carrier box that is driven by a rotating component to slowly rotate around a rotating axis. Combined with several sets of hollow holes on the side wall, the cooling medium can fully penetrate the carrier cavity and make full contact with the steel plate drill (or workpiece) inside, completely solving the problem of stacked cooling dead angles caused by traditional static bearing. The hexagonal prism design of the carrier box further improves the stress balance of the workpiece during rotation, avoids the internal stress caused by local temperature differences, effectively prevents cutting edge deformation and workpiece warping, and ensures the hardness, wear resistance and machining accuracy of the steel plate drill. The feeding component is synchronously driven by a motor, bevel gear, and twin screw, which drives the slide plate to move precisely and realizes the automated switching of the load-bearing component between the cooling box and the unloading table; the lifting device drives the load-bearing box to move up and down smoothly, completing the immersion in the cooling medium and the removal from the cooling medium. The whole process does not require manual pushing, which greatly reduces labor intensity. The drying unit uses a fan to send heated air from the hot air box into the carrier box through a connecting pipe and an output head (fitted with the air inlet of the rotating shaft). At the same time, the carrier box continues to rotate, and the hot air, together with the perforated holes, forms an internal and external airflow circulation, which quickly dries the cooling medium remaining on the surface and in the gaps of the workpiece.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 A shaping and cooling device for drilling steel plates includes a cooling box 1, a support assembly, a load-bearing assembly, and a feeding assembly. The support assembly includes legs 2, sliding frames 3, and crossbeams 4. The sliding frames 3 are symmetrically arranged on the left and right sides. The legs 2 are provided below the front and rear sides of the sliding frames 3. The front and rear ends of the two sets of sliding frames 3 are also symmetrically provided with crossbeams 4. A cooling box 1 is also provided below the two sets of sliding frames 3, and the cooling box 1 has a cooling cavity with an upper opening; A slide plate 5 is provided between the two sets of slide frames 3, and a feeding component that drives the slide plate 5 to move is also provided on the two sets of slide frames 3; The load-bearing assembly includes a lifter 6, a lifting plate 7, a load-bearing box 8, a rotating component, and a side plate 9. The output end of the lifter 6 passes through the slide plate 5 and is connected to the lifting plate 7. Side plates 9 are symmetrically arranged on the left and right sides below the lifting plate 7. Rotating shafts 10 passing through the side plates 9 are arranged on the left and right sides of the load-bearing box 8. A rotating component that drives the load-bearing box 8 to rotate is also provided on the lifting plate 7. A load-bearing cavity is provided inside the load-bearing box 8. Several sets of hollow holes are provided on the side wall of the load-bearing box 8.

[0019] Two sets of symmetrically arranged sliding frames 3 are connected by crossbeams 4 at the front and rear ends to form a rigid frame. The support legs 2 below provide stable support for the equipment, ensuring that there is no shaking or tilting during operation.

[0020] The slide frame 3 provides rotational support for the screw 26 of the feed assembly, and also provides a guide track for the translation of the slide plate 5, ensuring the accuracy of subsequent station switching.

[0021] In this embodiment, the feeding assembly includes a cover 21, a second motor 22, a first bevel gear 23, a second rotating shaft 24, a second bevel gear 25, and a screw 26. The screw 26 is rotatably disposed inside the slide frame 3. The left and right sides of the slide plate 5 are threadedly connected to the screw 26. One end of each of the two sets of slide frames 3 is provided with a cover 21. The second rotating shaft 24 is rotatably disposed inside the cover 21. The screw 26 passes through the corresponding slide frame 3 and cover 21 and is centrally connected to the first bevel gear 23. The second rotating shaft 24 is also provided with a second bevel gear 25 that meshes with the corresponding first bevel gear 23. The output end of the second motor 22 passes through the cover 21 and is connected to the second rotating shaft 24. Start the second servo motor, and the output end drives the second rotating shaft 24 inside the cover 21 to rotate. The second bevel gear 25 on the second rotating shaft 24 meshes with two sets of first bevel gears 23, and transmits power synchronously to the screws 26 in the sliding frames on both sides, so as to realize the synchronous rotation of the two screws 26. The left and right sides of the slide plate 5 are threadedly connected to the screw 26. When the screw 26 rotates, the threaded transmission converts the rotational motion into the horizontal linear motion of the slide plate 5, which drives the load-bearing component above to move horizontally. The servo motor can precisely control the rotation angle, realizing the precise positioning of the load-bearing box 8 at the two workstations directly above the cooling box 1 and directly above the unloading platform 28, without the need for manual intervention. In actual use, the carrier box 8 is in the shape of a regular hexagonal prism. One side of the carrier box 8 is provided with a hinged cover 11. One end of the hinged cover 11 is hinged to the carrier box 8, and the other end of the hinged cover 11 is connected to the carrier box 8 through a connector. The connector includes a buckle 12 and a retaining ring 13. The carrier box 8 is provided with a buckle 12, and the hinged cover 11 is provided with a retaining ring 13 that engages with the buckle 12. Below the two sets of sliding frames 3, there is also a feeding platform 28 that fits against the cooling box 1. The feeding platform 28 is provided with a feeding ramp, and the feeding platform 28 is also provided with a drying component for drying the carrier box 8.

[0022] Initially, the height of the lifting plate 7 is adjusted by the lifting device 6, and then the height of the carrying box 8 is adjusted. The carrying box 8 is located above the unloading platform 28. The buckle 12 and the retaining ring 13 are unlocked, the hinge cover 11 is opened, the material is placed into the carrying box 8, and the hinge cover 11 is closed. Guide rod 27 passes through slide plate 5, limiting the radial displacement of lifting plate 7 and ensuring a smooth and tilt-free lifting process. When the carrier box 8 moves horizontally to directly above the cooling box 1, the lifter 6 drives the lifting plate 7 to descend, so that the carrier box 8 and the internal steel plate drill are completely immersed in the cooling medium; after cooling is completed, the lifter 6 drives the lifting plate 7 to rise, causing the carrier box 8 to detach from the cooling medium; In this embodiment, the rotating component includes a first motor 14, a first gear 15, a second gear 16, a first rotating shaft 17, a third gear 18, a fourth gear 19, and a chain 20. The first motor 14 is located below the lifting plate 7, and the first gear 15 is located at the output end of the first motor 14. The upper part of the two sets of side plates 9 is rotatably equipped with the first rotating shaft 17, and the first rotating shaft 17 is equipped with the second gear 16 that meshes with the first gear 15. The two ends of the first rotating shaft 17 pass through the side plates 9 and are equipped with the third gear 18. The rotating shaft 10 is also equipped with the fourth gear 19 that is adapted to the corresponding third gear 18. The corresponding third gear 18 and fourth gear 19 are connected by the chain 20.

[0023] The first servo motor is started, and its output drives the first gear 15 to rotate, which meshes with the second gear 16 to drive the first rotating shaft 17 to rotate; the third gear 18 at both ends of the first rotating shaft 17 drives the fourth gear 19 on the rotating shaft 10 to rotate through the chain 20, thereby driving the carrier box 8 to rotate slowly around the rotating shaft 10. The perforated holes on the side wall of the bearing box 8 provide a flow channel for the cooling medium. During rotation, the internal steel plate drill changes its posture continuously, and the cooling medium can penetrate the bearing cavity in all directions and make full contact with the surface and gaps of the steel plate drill, avoiding stacked cooling dead corners. The design of the regular hexagonal prism bearing box 8 further improves the stress balance of the workpiece during rotation, ensures uniform cooling, and prevents deformation caused by internal stress.

[0024] After cooling is complete, the material needs to be further dried. The drying components include a fan 29, a hot air box 30, an auxiliary frame 31, a pusher 32, a pusher plate 33, a connecting pipe 34, and an output head 35. The auxiliary frame 31, the hot air box 30, and the fan 29 are symmetrically arranged on the left and right sides above the unloading platform 28. The auxiliary frame 31 is in the shape of a U-shaped opening at the bottom. The output end of the pusher 32 passes through the auxiliary frame 31 and is connected to the pusher plate 33. The pusher plate 33 is also provided with an output head 35 near the end of the rotating shaft 10. One end of the fan 29 is connected to the hot air box 30, and the other end of the fan 29 is connected to the output head 35 through the connecting pipe 34. The rotating shaft 10 is also provided with an air inlet that is compatible with the output head 35.

[0025] After the carrier box 8 is moved horizontally above the unloading platform 28, the pusher 32 on the auxiliary frame 31 is activated to push the push plate 33 so that the output head 35 precisely fits the air inlet on the rotating shaft 10, forming a sealed hot air conveying channel. The fan 29 draws the heated air out of the hot air box 30 and sends it into the carrier box 8 through the connecting pipe 34, the output head 35 and the air inlet; at this time, the carrier box 8 keeps rotating slowly, and the hot air flows out through the hollow holes in the side wall, forming an airflow circulation of "air inlet in box - air outlet in box", which quickly removes the residual cooling medium on the surface and gaps of the steel plate drill, and the drying efficiency is much higher than natural dripping and manual wiping. Hot air dries the inner wall of the carrier box 8 from the inside, preventing residual liquid inside the carrier box 8 and thus preventing hot materials from evaporating after entering the carrier box 8 and contacting the medium, reducing the possibility of steam harming the workers in the loading area. The drain pipe 36 on one side of the cooling tank 1 works in conjunction with the switch valve 37 to periodically discharge the used cooling medium, preventing impurities from accumulating and affecting the cooling effect, and ensuring the cleanliness of the cooling medium.

[0026] Both the first motor 14 and the second motor 22 are servo motors.

[0027] The present invention further provides a shaping and cooling method for drilling steel plates, comprising the following steps: Step 1: Initial state, the carrier box 8 is located above the unloading platform 28. At this time, the hinge cover 11 is located on the upper part of the carrier box 8. Open the hinge cover 11, load the material into the carrier box 8, and then close the hinge cover 11. Step 2: Start the second motor 22 through the control terminal, and the feeding component starts to work: The second motor 22 drives the second rotating shaft 24 to rotate, which drives the second bevel gear 25 to mesh with the two sets of first bevel gears 23, and then synchronously drives the screws 26 in the sliding frames 3 on both sides to rotate; the slide plate 5 moves with the screws 26 through the threaded connection, which drives the upper bearing component to move horizontally to the top of the cooling box 1, and completes the positioning of the cooling station. Step 3: Start the lifting device 6 to drive the lifting plate 7 to descend, so that the carrying box 8 and the internal workpiece are completely immersed in the cooling medium of the cooling box 1; start the first motor 14, and the rotating parts begin to work: the first motor 14 drives the first gear 15 to mesh with the second gear 16, driving the first rotating shaft 17 to rotate. The third gear 18 at both ends of the first rotating shaft 17 drives the fourth gear 19 on the rotating shaft 10 to rotate through the chain 20, thereby driving the carrying box 8 to rotate slowly around the rotating shaft 10; the workpiece rotates with the carrying box 8 in the cooling medium, and the cooling medium fully contacts the surface of the workpiece through the hollow holes on the side wall of the carrying box 8 to achieve uniform cooling and shaping, avoiding workpiece deformation caused by local temperature differences. The cooling time is set according to the workpiece specifications. Step 4: After the cooling time is reached, start the lifting device 6 to lift the carrier box 8 and remove it from the cooling medium; start the feeding component again to drive the slide plate 5 to move horizontally above the unloading platform 28; start the drying component: the fan 29 delivers the heated air in the hot air box 30 to the output head 35 through the connecting pipe 34, and at the same time starts the pusher 32 on the auxiliary frame 31 to push the push plate 33 so that the output head 35 fits against the air inlet on the rotating shaft 10; the carrier box 8 continues to rotate slowly, and the hot air enters the interior of the carrier box 8 through the air inlet, forming an airflow circulation with the side wall perforation, quickly drying the cooling medium remaining on the surface of the workpiece; Step 5: After drying is complete, unload the material from the carrier box 8.

9. A steel plate drill with a drilling positioning mechanism according to claim 1, characterized in that: The outer surface of the U-shaped pull rod (703) is provided with an anti-slip layer, and the outer surface of the anti-slip layer is uniformly provided with anti-slip texture.

10. A method for positioning a steel plate drill with a drilling positioning mechanism, comprising a steel plate drill with a drilling positioning mechanism as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Place the steel plate to be drilled inside the L-shaped clamping plate (1), and move the arc-shaped extrusion plate (702) outward by pulling the U-shaped pulling rod (703). Release the extrusion spring column (701), so that the arc-shaped extrusion plate (702) can be laterally extruded and clamped by the side plate (704) and rubber pad (705) under the elastic force of the extrusion spring column (701), thus completing the initial positioning of the steel plate. Step 2: Then start the electric push rod (607). The electric push rod (607) pushes the pusher frame (609) to move along the guide horizontal hole of the guide horizontal plate (610). The pusher frame (609) drives the push rod (606) to rotate, and then pushes the pressing horizontal plate (604) to move downward through the telescopic column (603), so that the anti-slip pad on the lower surface of the pressing horizontal plate (604) is tightly attached to the upper surface of the steel plate, thus completing the pressing and fixing of the steel plate. Step 3: Input the preset drilling position parameters through the controller (15). The controller (15) starts the drive motor (8) according to the parameter instructions. The drive motor (8) drives the longitudinal screw (9) to rotate, and then drives the moving plate (10) to move longitudinally along the longitudinal screw (9) until it moves to the preset longitudinal position. Step 4: Simultaneously start the rotating motor (13), the rotating motor (13) drives the transverse screw (12) to rotate, the transverse screw (12) drives the transverse moving plate (14) to move laterally, and at the same time the laser probe (16) scans the surface of the steel plate in real time and feeds back the position signal to the controller (15). Step 5: The controller (15) finely adjusts the position of the transverse moving plate (14) according to the feedback signal of the laser probe (16) so that the drill bit (18) is precisely aligned with the preset drilling position to complete the drilling positioning. Then the telescopic drilling machine (17) is started. The telescopic drilling machine (17) drives the drill bit (18) to move downward and rotate at high speed to perform drilling operations on the steel plate. Step 6: Simultaneously start the water pump (501) and the vacuum cleaner (506). The water pump (501) delivers the cooling water in the water tank (502) to the cooling nozzle (505) through the telescopic water pipe (503) to cool the drill bit (18) and the drilling area. The vacuum cleaner (506) sucks up and collects the metal waste generated during drilling through the dust hood (509) and the dust suction telescopic pipe (507). Step 7: After drilling is completed, turn off the telescopic drill (17), water pump (501) and vacuum cleaner (506), start the electric push rod (607) in reverse, so that the pressing plate (604) returns to the upward position, pull the U-shaped pull rod (703) to release the arc-shaped extrusion plate (702), take out the steel plate after drilling, and complete one drilling operation.
