Description

Technical Field

[0001] This invention relates to the field of drilling and dust removal technology, and specifically to a drilling machine for rolling mill processing. Background Technology

[0002] As a core component of steel rolling production lines, the machining accuracy of cooling holes and process positioning holes on the surface of rolling mill rolls directly determines the shape control accuracy of subsequent rolling processes and the service life of the rolls themselves. Currently, for deep hole machining of large metallurgical rolls, the industry generally uses CNC drilling machines to complete the drilling process. To avoid localized high-temperature ablation of the cutting edge caused by friction between the high-speed rotating drill bit and the high-hardness roll substrate, and to suppress the diffusion of metal chips and dust generated during the drilling process, the industry's conventional technical method is to install high-pressure spray nozzles next to the drilling station to continuously spray cooling water into the drilling area, thereby achieving the effects of immediate cooling and simultaneous dust removal.

[0003] However, most existing conventional roll drilling equipment spray cooling systems do not have a targeted closed-loop collection and filtration structure for impurity mixtures. The cooling water sprayed from the nozzles carries a large amount of roll metal debris, drill bit wear particles, and dust impurities generated during the drilling process, and then flows freely on the equipment's worktable without undergoing special collection and purification treatment. This has led to a series of long-standing practical problems in the industry.

[0004] Currently, most conventional cooling water treatment solutions in the industry only use simple single-layer grids for coarse filtration, which cannot effectively intercept fine metal abrasive particles. A large number of hard impurities still remain in the filtered cooling water, which cannot solve the above problems at the root. Therefore, developing a special punching machine that is suitable for the rolling mill punching operation and can efficiently complete the closed-loop collection and multi-stage precision filtration of the impurity-containing mixed liquid has become an urgent technical need to be addressed in this field. Summary of the Invention

[0011] Furthermore, the linkage also includes a power unit for driving the long rod to perform vertical reciprocating motion; the long rod is slidably connected to the concave block, and the long rod can perform vertical reciprocating motion within the auxiliary hole.

[0012] Furthermore, the auxiliary unit also includes an auxiliary rod and a second spring; the base plate is slidably connected to the bottom groove; one end of the auxiliary rod is fixedly connected to the base plate, and the other end of the auxiliary rod abuts against the long rod; the two ends of the second spring are respectively connected to the base plate and the bottom groove.

[0014] Furthermore, it also includes a motion unit set inside the side box; the motion unit includes a screw, a guide rod, and a moving part for driving the screw to rotate; the screw is rotatably connected to the side box; the guide rod is fixedly connected to the side box; the drive unit is a nut seat; the nut seat is threadedly connected to the screw, slidably connected to the guide rod, and fixedly connected to the auxiliary block.

[0015] Furthermore, the power unit includes a second cam, a vertical rod, an inner plate, and a fourth spring; the second cam is fixedly connected to the screw; one end of the vertical rod is fixedly connected to the long rod, and the other end of the vertical rod passes through the sliding hole and is fixedly connected to the inner plate; the inner plate abuts against the second cam; the two ends of the fourth spring are respectively connected to the long rod and the concave block.

[0016] The principles and advantages of this scheme are: 1. Cooling water containing a large amount of rolling mill metal shavings, drill bit wear particles and drilling dust first passes through a coarse-pore filter plate to initially intercept large-volume impurities. The entire filtration process is completed within the water filtration mechanism, which completely avoids the problem of cooling water carrying impurities and flowing freely on the equipment workbench in traditional solutions. This prevents the work site from becoming dirty and messy, with debris scattered everywhere and difficult to clean.

[0017] 2. The water after coarse filtration flows further to the fine pore filter plate, completing the deep interception of small hard abrasive particles. The combination of two-stage filtration can completely separate the small metal impurities that cannot be blocked by traditional single-layer grids from the cooling water. The impurity content of the filtered cooling water is greatly reduced, realizing the closed-loop purification cycle of cooling water. This fundamentally solves the industry pain point of residual hard impurities wearing down nozzles and scratching the surface of the rolling mill due to the backflow of cooling water.

[0018] 3. The coarse-pore filter plate is continuously rotated by the rotating shaft. The scraper fixed to the inner wall of the filter cylinder is always in contact with the surface of the coarse-pore filter plate. During the rotation, the scraper can continuously scrape off the metal debris that remains on the surface of the coarse-pore filter plate, avoiding the accumulation of large particles of impurities that block the filter holes, and ensuring that the coarse filtration process maintains smooth water permeability for a long time.

[0019] 4. Driven by the power unit, the fine-pore filter plate makes a stable vertical reciprocating motion along the guide cylinder. It is equipped with an inner vibrating block that rotates circumferentially with the rotating shaft. The inner vibrating block will periodically impact the fine-pore filter plate that has moved to the corresponding trajectory position. Through mechanical vibration, the small hard particles embedded in the mesh of the fine-pore filter plate are dislodged, avoiding the problem of long-term blockage of the fine pores leading to a decrease in water permeability.

[0020] 5. The bottom brush, which moves circumferentially with the inner vibrating block, can simultaneously sweep across the filter surface of the fine-pore filter plate, quickly sweeping away residual impurities that have been shaken off the filter surface, further ensuring the permeability of the fine-pore filter plate, allowing the entire filtration system to operate continuously for a long time without frequent shutdowns to disassemble and clean the filter components, and adapting to the operational needs of long-term deep hole processing of large rollers.

[0021] 6. When the slide cylinder moves back and forth along the long rod, it will drive the shovel to sweep horizontally back and forth at the bottom of the filter cylinder. This breaks the limitation of the traditional fixed-position shovel that can only clean a local area. The cleaning trajectory of the shovel covers more of the sludge accumulation area on the surface of the fine pore filter plate, thereby preventing impurities from being washed up by the water flow and adhering to the surface of the fine pore filter plate again. This further consolidates the long-term permeability effect of the two-stage filtration system and reduces the probability of filter plate clogging.

[0022] 7. The fine-pore filter plate itself is in a state of continuous vertical reciprocating motion, and the scraper block moves vertically in sync with it. It can always maintain a stable fit with the surface of the fine-pore filter plate, and will not have the problems of excessive gap and insufficient scraping force that occur when the traditional fixed-height scraper block moves up and down the filter plate. It avoids the situation of impurities remaining due to contact gaps, and ensures that each scraping can completely remove the metal abrasive particles and drilling dust attached to the surface of the filter plate with stable pressure.

[0023] Furthermore, the vertical reciprocating motion of the shovel block generates a combined force of small-amplitude knocking vibration and horizontal scraping. For hard, fine metal impurities that cannot be shaken out by the vibration of the inner shovel block alone and are stuck inside the filter holes, the stubborn impurities embedded in the filter holes can be completely removed by the combination of vertical micro-knocking and horizontal scraping, which greatly reduces the clogging rate of the filter holes, continuously ensures the water permeability efficiency of the fine pore filter plate, and avoids a significant decrease in filtration efficiency as the operating time increases.

[0024] 8. The horizontal circumferential sweeping motion of the bottom brush can traverse more radial areas of the fine pore filter plate. Combined with the vertical reciprocating motion forming up-and-down micro-scraping, it can create a cross-shaped three-dimensional cleaning trajectory. This can cover the entire filtration area of ​​the fine pore filter plate, and also reach the edges of the filter holes and tiny depressions on the mesh surface, which are difficult to clean by traditional unidirectional motion and bottom brush. This more thoroughly removes fine metal abrasive particles and drilling dust adhering to various parts of the filter surface.

[0025] Meanwhile, the vertical reciprocating motion of the bottom brush can create a gentle, elastic, dynamic brushing force. Unlike ordinary bottom brushes that can only unidirectionally rub the filter plate surface, the dynamically vertically micro-moving bristles can partially penetrate into the shallow pores of the fine-pore filter plate, directly brushing out semi-embedded hard impurities stuck at the pore inlet. Combined with the vibration of the internal vibrating block, this greatly improves the cleaning efficiency of stubborn embedded impurities, further ensuring the water permeability of the fine-pore filter plate and preventing progressive clogging of the pores.

[0048] The moving parts include a gear 32, a plurality of first arc-shaped racks 33 equidistantly arranged along the circumferential direction of the filter cylinder 4, a plurality of second arc-shaped racks equidistantly arranged along the circumferential direction of the filter cylinder 4, an annular chamber inside the filter cylinder 4, and an annular hole in the annular chamber; a screw 28 passes through the annular hole and extends into the annular chamber; the gear 32 is located in the annular chamber and is fixedly connected to the screw 28; the first arc-shaped racks 33 are fixedly connected to the bottom of the annular chamber and are located between two adjacent second arc-shaped racks; the second arc-shaped racks are fixedly connected to the top of the annular chamber; the upper and lower sides of the gear 32 can respectively mesh with the first arc-shaped racks 33 and the second arc-shaped racks.

[0049] Specific implementation process: The roll is placed into the punching box 2 along the fixed sleeve 3, and the fixed sleeve 3 fixes the roll. Then, the lifting cylinder 11 and the drive motor work together to drive the drill block to punch the roll. During the punching process, the booster pump in the water guide channel guides the filtered cooling water in the water filter cylinder 4 into the bottom pipe 14 and the auxiliary pipe 15, and finally discharges it through the regulating pipe 16. The water is then used to cool, remove dust, and filter water in the punching area, which greatly improves the punching efficiency and quality of the roll.

[0050] All regulating pipes 16 are equidistantly distributed along the length of the auxiliary pipe 15 and can be freely hinged and rotated. Operators can flexibly adjust the spray angle of each regulating pipe 16 according to the actual needs of different drilling positions on the roll, so that the cooling water can accurately cover the core area of ​​the drilling operation. Compared with the traditional fixed-direction spray nozzles, it can remove the local high temperature generated by the friction between the drill bit and the roll base 1 to the greatest extent, avoid high temperature erosion of the cutting edge, and greatly extend the service life of the drill bit. It can also achieve full coverage and capture of metal dust generated by drilling, completely suppress the dust diffusion in the working area, improve the workshop working environment, and at the same time, the directional spraying of cooling water also reduces the waste of water resources caused by ineffective spraying.

[0051] Cooling water containing a large amount of rolling mill metal shavings, abrasive particles from drill bit wear, and drilling dust first passes through a coarse-pore filter plate to initially intercept large-volume impurities. The entire filtration process is completed within the water filtration mechanism, completely avoiding the problem of cooling water carrying impurities and freely flowing on the equipment's work surface in traditional solutions. This prevents the work site from becoming dirty and messy, with debris scattered everywhere and difficult to clean.

[0052] After coarse filtration, the water flows further to the fine pore filter plate, completing the deep interception of small hard abrasive particles. The combination of two-stage filtration can completely separate the small metal impurities that traditional single-layer grids cannot block from the cooling water. The impurity content of the filtered cooling water is greatly reduced, realizing the closed-loop purification cycle of cooling water. This fundamentally solves the industry pain point of residual hard impurities wearing down nozzles and scratching the surface of the rolling mill due to the backflow of cooling water.

[0053] During water filtration by the coarse filter plate 7, the output shaft of the power motor drives the rotating shaft 6 to rotate. During rotation, the coarse filter plate is continuously rotated by the rotating shaft 6. The scraper 17, which is fixed to the inner wall of the water filter cylinder 4, is always in contact with the surface of the coarse filter plate. During the rotation, the scraper 17 can continuously scrape off the metal debris remaining on the surface of the coarse filter plate, preventing large particles of impurities from accumulating and clogging the filter holes, and ensuring that the coarse filtration process maintains smooth water permeability for a long time.

[0054] During the rotation of the rotating shaft 6, the meshing of the first bevel gear 32 and the second bevel gear 32 drives the power shaft to rotate. During the rotation of the power shaft, the first cam 27 rotates synchronously. During the rotation of the first cam 27, the fine-pore filter plate can perform vertical reciprocating motion under the combined action of the first cam 27 and the third spring.

[0055] During the stable vertical reciprocating motion of the fine-pore filter plate along the length of the guide cylinder 8, an inner vibrating block 20 that rotates synchronously with the rotating shaft 6 is used. The inner vibrating block 20 periodically impacts the fine-pore filter plate that has moved to the corresponding trajectory position. Through mechanical vibration, the small hard particles embedded in the mesh of the fine-pore filter plate are dislodged, thus avoiding the problem of long-term blockage of the fine pores leading to a decrease in water permeability.

[0056] During the circumferential rotation of the side box 18 with the rotating shaft 6, the gear 32 meshes with the first arc-shaped rack 33 and the second arc-shaped rack respectively, thereby enabling the gear 32 to drive the screw 28 to rotate forward and backward. During the rotation of the screw 28, the nut seat 34 can drive the auxiliary block 19 to reciprocate along the length of the guide rod 29.

[0057] During the movement of the auxiliary block 19, it can not only expand the contact range between the inner vibrating block 20 and the fine pore filter plate, but also drive the bottom brush 21, which moves synchronously with the inner vibrating block 20, to fully and comprehensively sweep across the filter surface of the fine pore filter plate, quickly sweeping away the residual impurities that have been shaken off the filter surface, further ensuring the permeability of the fine pore filter plate, allowing the entire filtration system to operate continuously for a long time without frequent shutdowns to disassemble and clean the filter components, thus adapting to the operational needs of long-term deep hole processing of large rolls.

[0058] During the lateral reciprocating motion of the inner vibrating block 20, the inner vibrating block 20 drives the sliding cylinder 24 to reciprocate along the length of the long rod 23 via the hinge rod 26. During the reciprocating motion of the sliding cylinder 24, it drives the shovel block 25 to simultaneously perform lateral reciprocating sweeping at the bottom of the water filter cylinder 4. This breaks the limitation of the traditional fixed-position shovel block 25, which can only clean a local area. It allows the cleaning trajectory of the shovel block 25 to cover more of the sludge accumulation area on the surface of the fine pore filter plate, thereby preventing impurities from being washed up by the water flow and adhering to the surface of the fine pore filter plate again. This further consolidates the long-term permeability effect of the two-stage filtration system and reduces the probability of filter plate clogging.

[0059] During the rotation of screw 28, second cam 30 rotates synchronously. During the rotation of second cam 30, the inner plate, under the action of second cam 30 and fourth spring, drives vertical rod 31 to perform vertical reciprocating motion, and long rod 23 moves synchronously. Therefore, while the fine pore filter plate itself is in a state of continuous vertical reciprocating motion, the scraper block 25, driven by long rod 23, performs synchronous vertical follow-up motion, which can always maintain stable contact with the surface of fine pore filter plate. It avoids the problems of excessive contact gap and insufficient scraping force that occur when the traditional fixed-height scraper block 25 moves up / down on the filter plate, and avoids the situation where impurities remain due to contact gaps. It ensures that each scraping can completely remove metal abrasive particles and drilling dust attached to the surface of the filter plate with stable pressure.

[0060] Furthermore, the vertical reciprocating motion of the shovel block 25 generates a small-amplitude knocking vibration combined with a horizontal scraping force. For hard, fine metal impurities that cannot be shaken out by the vibration of the inner vibrating block 20 alone and are stuck inside the filter holes, the stubborn impurities embedded in the filter holes can be completely removed by the combination of vertical micro-knocking and horizontal scraping, which greatly reduces the clogging rate of the filter holes, continuously ensures the water permeability efficiency of the fine pore filter plate, and avoids a significant decrease in filtration efficiency as the operating time increases.

[0061] During the vertical reciprocating motion of the long rod 23, the auxiliary rod, under the action of the long rod 23 and the second spring, drives the base plate to perform a vertical reciprocating motion. During the base plate's movement, the bottom brush 21 moves synchronously. The lateral circumferential sweeping of the bottom brush 21 can traverse more radial areas of the fine-pore filter plate. Combined with the up-and-down micro-scraping formed by the vertical reciprocating motion, a cross-shaped three-dimensional cleaning trajectory is created. This not only covers the entire filtration area of ​​the fine-pore filter plate but also reaches hidden areas that are difficult to clean with traditional unidirectional motion and the bottom brush 21, such as the edges of the filter holes and tiny depressions on the mesh surface. This more thoroughly removes fine metal particles and drilling dust adhering to various parts of the filter surface. Meanwhile, the vertical reciprocating motion of the bottom brush 21 can generate a gentle, elastic, dynamic brushing force. Unlike ordinary bottom brushes 21, which can only unidirectionally rub the surface of the filter plate, the dynamically vertically micro-moving bristles can partially penetrate into the shallow pores of the fine-pore filter plate, directly brushing out semi-embedded hard impurities stuck at the entrance of the pores. Combined with the vibration of the inner vibrating block 20, the cleaning efficiency of stubborn embedded impurities is greatly improved, further ensuring the water permeability of the fine-pore filter plate and preventing the pores from becoming progressively clogged.

[0062] In summary, relying on the rotating scraping of coarse-pore filter plates, the reciprocating vibration of fine-pore filter plates for clogging removal, the directional spraying cooling and dust removal by regulating pipe 16, and the linkage of inner vibrating block 20 with sliding cylinder 24, shovel block 25, and bottom brush 21 to achieve a full-link collaborative structure of horizontal and vertical reciprocating compound motion, a closed-loop purification process from coarse filtration of large particles to deep clogging removal of fine pores can be achieved. This results in long-term filtration with no dead angle coverage, dynamic fit, and low-loss plate protection. It avoids the pain points of traditional equipment such as cooling water overflow, easy clogging of filter plates, and many blind spots in cleaning. It can also continuously ensure cooling accuracy and filtration stability during long-term deep hole processing of rolls, significantly extend the service life of drill bits and filter plates, ultimately improve the processing accuracy of roll holes, improve the working environment, and reduce the burden of manual maintenance.
