Description

Technical Field

[0001] This invention relates to the field of precision bearing processing equipment, and in particular to a metal circular saw for cleaning debris in wheel hub bearing manufacturing. Background Technology

[0002] Automotive wheel hub bearings are key precision components of automotive chassis running systems. They mostly use high-carbon chromium bearing steel bars such as GCr15 as raw materials. They need to be precisely cut using a metal circular saw to provide qualified blanks for subsequent ring forging, turning, grinding, heat treatment and other processes. The cutting accuracy and surface cleanliness directly determine the precision, service life and operational reliability of the finished wheel hub bearing.

[0003] During high-speed sawing, carbide saw blades cutting high-hardness bearing steel will produce a large number of fine metal chips and powder debris, which will be mixed with cutting oil to form sludge-like debris. These debris have a complex shape, including fine powder, curled long chips, and burr fragments, which are very easy to adhere to the saw blade tooth grooves.

[0004] Most chip removal relies on manual, periodic shutdowns for cleaning, supplemented by fixed simple scrapers and ordinary wire brushes. This method cannot reach deep into the tooth grooves and corners of the fixtures to remove fine oil chips, resulting in incomplete chip removal. Frequent shutdowns disrupt the cycle time of automated production lines, reduce production capacity, and increase labor costs. In addition, manual chip removal poses safety hazards such as mechanical scraping and flying metal chips. Summary of the Invention

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: most chip removal relies on manual periodic shutdowns for cleaning, supplemented by fixed simple scrapers and ordinary wire brushes, which cannot reach deep into the tooth grooves and dead corners of the fixtures to remove fine oil chips, resulting in incomplete chip removal. Frequent shutdowns disrupt the cycle time of automated production lines, reduce production capacity, and increase labor costs.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1 , Figure 3 , Figure 11 A metal circular saw for cleaning debris in wheel hub bearing manufacturing includes a housing 1 and a mounting frame 2 installed inside the housing 1. A mounting plate 13 is installed on the outer surface of the mounting frame 2. The mounting plate 13 slides laterally on the mounting frame 2 and can be driven by an electric telescopic rod or a hydraulic rod in actual use. A mounting groove 49 is provided on the mounting plate 13. A cutting component 48 is installed inside the mounting plate 13. The cutting component 48 includes a protective cover 15 and a saw blade 14. The protective cover 15 is installed on the mounting plate 13. The saw blade 14 is a prior art material used to cut bearing steel bars and is rotatably connected inside the protective cover 15. The protective cover 15 can further prevent large areas of debris from flying out of the saw blade 14. The following components are installed on one end of the mounting frame 2 near the mounting plate 13: a pneumatic component 47, a drive component 50, a separation component 44, a magnetic suction component 45, and a buffer component 46.

[0023] Reference Figures 3-5 , Figure 11 , Figure 13 A concave box 12 is installed in the mounting slot 49. The concave box 12 is detachably installed in the mounting slot 49, in conjunction with the attached... Figure 11As shown, the concave box 12 can be fixed with screws. The pneumatic assembly 47 is installed on the concave box 12. The pneumatic assembly 47 includes a square plate 32 and vertical plates 16. Two square plates 32 are provided and are slidably connected to both ends of the concave box 12. The vertical plates 16 are fixedly connected to the ends of the square plates 32 away from the concave box 12. Two vertical plates 16 are also provided, and scrapers 26 are slidably connected to them. One vertical plate 16 is located in the mounting groove 49. The two vertical plates 16 are located on both sides of the saw blade 14. By moving the two vertical plates 16 in the center, the scrapers 26 can clean both sides of the saw blade 14 simultaneously. The vertical plates 16 do not contact the saw blade 14. Only the rotating roller 29 and the scrapers 26 contact the saw blade 14. The outer surface of the rotating roller 29 is made of wear-resistant and high-temperature resistant rubber material, which has good performance. The scraper 26 has elasticity, which increases the friction with the saw blade 14. A special scraper is provided at the end of the scraper 26 near the saw blade 14 to avoid damage to the saw blade 14. A return spring is provided between the lower end of the scraper 26 and the outer surface of the vertical plate 16. When the end of the scraper 26 abuts against the saw blade 14, the return spring will be stretched as the vertical plate 16 continues to move toward the saw blade 14. The elastic potential energy of the return spring is used to squeeze the scraper 26 tightly against the side wall of the saw blade 14. A through groove is provided on the scraper 26. Fixed blocks 21 are fixedly connected to the upper surfaces of both ends of the concave box 12. A first spring 22 is fixedly connected between the fixed block 21 and the vertical plate 16. The first spring 22 is used to pull the vertical plate 16 to return to its original position. The first spring 22 is set on the upper side of the square plate 32. The pneumatic assembly 47 is used to clean the debris on the surface of the cutting part 48.

[0024] Reference Figure 1 , Figure 2 , Figure 8 , Figure 10 The mounting frame 2 has a feeding plate 11 and a support plate 8 on one side. A material collection box can be placed on one side of the feeding plate 11 to collect the cut metal parts. The support plate 8 is set on the upper side of the feeding plate 11. The drive assembly 50 is installed between the feeding plate 11 and the support plate 8. The drive assembly 50 includes a column 42 and a fourth spring 43. The lower end of the column 42 is fixedly connected to the upper surface of the feeding plate 11. The column 42 is perpendicular to the feeding plate 11. A sealing cavity is opened on the support plate 8. The upper end of the column 42 is slidably connected in the sealing cavity. A sealing gasket is installed on the end of the column 42 in the sealing cavity to increase the seal between the column and the cavity. The sealing effect between the walls is achieved by a connecting pipe 19 that is fixedly connected between the sealing cavity and the concave box 12. Two fourth springs 43 are fixedly connected between the feed plate 11 and the support plate 8. The two fourth springs 43 are respectively set on both sides of the column 42. When the cut metal parts fall onto the support plate 8, the support plate 8 will slide down the column 42 due to the weight of the metal parts. At the same time, the support plate 8 can buffer the falling metal parts. When the metal parts are removed from the support plate 8, the fourth spring 43 will push the support plate 8 to move up and reset. The drive assembly 50 is used to drive the pneumatic assembly 47 to complete the cleaning of the cut parts 48.

[0025] Reference Figures 3-5 , Figure 7 The separation component 44 is disposed on one side of the pneumatic component 47 to assist the pneumatic component 47 in cleaning the cut piece 48. The separation component 44 includes a movable plate 17, a rotating roller 29, a piston plate 31, and a sealing box 28. The movable plate 17 is slidably connected inside the vertical plate 16 and slides laterally on the vertical plate 16. The upper end of the rotating roller 29 is rotatably connected to the inner wall of the movable plate 17 and is vertically arranged. The sealing box 28 is fixedly connected to one side of the movable plate 17. The piston plate 31... One end of the piston plate 31 is slidably connected inside the sealed box 28. The outer surface of the piston plate 31 is sealed to prevent air leakage when the piston plate 31 compresses the gas inside the sealed box 28. The other end of the piston plate 31 is fixedly connected to a slider 30. The lower end of the rotating roller 29 is fixedly connected to a reciprocating screw 27. The slider 30 is mounted on the reciprocating screw 27. When the reciprocating screw 27 rotates, it can drive the slider 30 to move up and down reciprocally. Air vents 38 are opened on the lower side wall of the sealed box 28. All air vents 38 are inclined. The oblique arrangement allows the exhaust gas to reach the tooth groove of the saw blade 14. The separation assembly 44 also includes a second spring 23, a cam 24, and a rotating shaft 25. The second spring 23 is fixedly connected between the moving plate 17 and the vertical plate 16. The second spring 23 is used to pull the moving plate 17 to reset and move. A protrusion is provided on one side of the vertical plate 16. One end of the rotating shaft 25 is rotatably connected to the protrusion. The protrusion is used to support the rotating shaft 25. A gear is provided on the other end of the rotating shaft 25. One end of the cam 24 is fixedly connected to the rotating shaft 25. The cam 24 is located on one side of the moving plate 17. A through groove is located on one side of the moving plate 17. When the rotating shaft 25 rotates, it can drive the cam 24 to flip from a vertical state to an oblique state. The cam 24 pushes the moving plate 17 to slide on the vertical plate 16 and stretches the second spring 23. The upper inner wall of the through groove is provided with teeth. The scraper 26 meshes with the gear through the teeth. When the scraper 26 slides laterally on the vertical plate 16, it can drive the rotating shaft 25 to rotate by meshing with the gear through the teeth.

[0026] Reference Figure 1 , Figure 4 , Figure 6Two support plates 35 are fixedly connected to one side of the concave box 12. The support plates 35 are L-shaped. A third spring 33 is fixedly connected to the end of the support plate 35 away from the concave box 12. The third spring 33 has strong toughness and can automatically recover after bending. An impact plate 36 is fixedly connected to the end of the third spring 33 away from the support plate 35. Multiple vibrating plates 37 arranged in an equidistant array are fixedly connected to one side of each of the two vertical plates 16. The two impact plates 36 are respectively positioned between two adjacent vibrating plates 37. As the vertical plate 16 moves laterally, the sidewalls of the vibrating plates 37 push the impact plates 36 one by one, causing the impact plates 36 to compress the third spring 33 and deform. When the vibrating plate 37 moves away from its current position, the impact plate 36 quickly returns to its original position under the elastic force of the third spring 33 and impacts the next adjacent vibrating plate 37, thereby making the entire... A vertical plate 16 generates continuous high-frequency vibration. A limiting plate 7 is fixedly connected to the mounting plate 13. A sliding groove is provided on the limiting plate 7. A horizontal bar 5 is fixedly connected to the mounting frame 2. The end of the horizontal bar 5 away from the mounting frame 2 is slidably connected in the sliding groove. A water spray pipe 6 is hinged to the limiting plate 7. A conduit 4 is fixedly connected to the water spray pipe 6. The conduit 4 is a highly wear-resistant hose. The water spray pipe 6 can tilt after being restricted by the horizontal bar 5. Through a micro water pump installed on the external conduit 4, the cutting fluid in the storage tank is continuously transported to the water spray pipe 6 through the conduit 4. The cutting fluid is then sprayed onto the saw blade 14 and the scraper 26 through the water spray pipe 6, which can further wash the saw blade 14 and also wash away the metal chips accumulated on one side of the scraper 26. A first torsion spring is provided between the water spray pipe 6 and the limiting plate 7. A cover plate 3 is slidably connected to the outer surface of the outer shell 1. Figure 1 As shown, when the cover plate 3 is slid to one side of the outer casing 1, it is convenient for the staff to inspect the equipment inside the outer casing 1. When working, the cover plate 3 is slid to the middle part of the outer casing 1, so that only the support plate 8 and the material feeding plate 11 are exposed. During processing, it can protect the staff and prevent debris from falling on the staff, while not affecting the normal cutting and feeding of metal parts.

[0027] Reference Figure 3 , Figure 4 , Figure 6 , Figure 12A magnetic suction assembly 45 is installed on one side of the concave box 12. The magnetic suction assembly 45 includes an L-shaped plate 34 and a magnetic plate 18. The L-shaped plate 34 is fixedly connected to one side of the concave box 12, and the magnetic plate 18 is fixedly connected to the L-shaped plate 34. One end of the L-shaped plate 34 has a groove, and the magnetic plate 18 is located in the groove, with its upper end flush with the L-shaped plate 34. The magnetic plate 18 is located on one side of the saw blade 14 and will attract metal chips in the tooth groove of the saw blade 14. A push plate 20 is slidably connected to the L-shaped plate 34. When the push plate 20 moves laterally, its end can push the metal chips on the outer surface of the magnetic plate 18. When the metal debris is pushed to the end of the L-shaped plate 34, since the L-shaped plate 34 is made of highly corrosion-resistant wood, it does not have an adsorption force on the metal debris. Therefore, after the metal debris moves away from the magnetic plate 18, it is no longer adsorbed and falls off under its own weight. A debris collection box can be placed in the outer casing 1 to facilitate the collection of the fallen debris. A horizontal spring is provided between one end of the push plate 20 and the end of the L-shaped plate 34. When the support rod 39 no longer exerts a pushing force on the push plate 20, the horizontal spring is used to pull the push plate 20 back to its original position. The magnetic suction component 45 is used to assist the separation component 44 in cleaning the cut piece 48.

[0028] Reference Figures 8-10 A buffer assembly 46 is installed on one side of the support plate 8. The buffer assembly 46 includes a cylinder 10 and a rotating rod 40. The cylinder 10 is fixedly connected to one side of the support plate 8, and the rotating rod 40 is rotatably connected to the cylinder 10. The rotating rod 40 is disposed through the cylinder 10. The connection between the rotating rod 40 and the upper and lower end side walls of the cylinder 10 is sealed to prevent the hydraulic oil inside the cylinder 10 from flowing out. A baffle 9 is fixedly connected to the rotating rod 40, and a fan blade 41 is fixedly connected to the outer surface of the rotating rod 40. The fan blade 41 is disposed inside the cylinder 10 and has a circular hole. The cylinder 10 is filled with hydraulic oil. When the metal part slides down the support plate 8, it pushes the baffle 9, causing the baffle 9 to drive the rotating rod 40 to rotate on the cylinder 10. The hydraulic oil has a certain effect on the movement of the fan blade 41. A certain amount of resistance slows down the rotation speed of the rotating rod 40, so the baffle 9 can flip slowly, which prolongs the time that the metal part stays on the support plate 8. Therefore, the cleaning time of the separation component on the saw blade 14 is also extended. The lower end of the rotating rod 40 is fixedly connected to the support rod 39, which is set on one side of the push plate 20. When the baffle 9 flips, it will drive the support rod 39 to move through the rotating rod 40. The support rod 39 can push the push plate 20 to slide on the L-shaped plate 34 and the magnetic plate 18. A second torsion spring is provided between the rotating rod 40 and the bottom wall of the cylinder 10. When the metal part is separated from the support plate 8, the support plate 8 moves up and resets. At the same time, the baffle 9 and the rotating rod 40 reset under the action of the second torsion spring. The buffer component 46 is used to drive the magnetic suction component 45.

[0029] In this invention, as shown in the appendix Figure 1As shown, one end of the conduit 4 is connected to an external cutting fluid storage tank. When the saw blade 14 moves laterally with the mounting plate 13 through the protective cover 15, it can cut the metal part on one side by continuously rotating. At the same time, the water spray pipe 6 moves synchronously with the mounting plate 13 through the limiting plate 7. At this time, the crossbar 5 no longer has a limiting effect on the water spray pipe 6. The water spray pipe 6 is always in a vertical state under the action of the first torsion spring. At this time, the cutting fluid in the storage tank is continuously transported to the water spray pipe 6 through the conduit 4 by the micro water pump installed on the external conduit 4, and the cutting fluid is sprayed onto the metal part through the water spray pipe 6. When the saw blade 14 cuts the metal part, it not only cools the saw blade 14, but also washes off the metal debris on the saw blade 14 and the metal part to a certain extent.

[0030] After the metal part is cut, it falls onto the pallet 8. At this time, the mounting plate 13, protective cover 15, and saw blade 14 reset and move away from the metal part, facilitating continued feeding and subsequent cutting. The cut metal part on the pallet 8 is limited by the baffle 9 and will not slide down quickly. Under the weight of the cut metal part, the pallet 8 slides vertically downward on the column 42, compressing the fourth spring 43. As the pallet 8 moves downward, the column 42 can compress the gas in the sealed cavity and enter the concave box 12 through the connecting pipe 19. As the gas in the concave box 12 increases... When the air pressure increases, it will push the square plate 32 to slide inside the concave box 12. At this time, the vertical plates 16 on both sides of the saw blade 14 move in the center and stretch the first spring 22. As the two vertical plates 16 move in the center and approach the saw blade 14, the scrapers 26 on the two vertical plates 16 first contact the side wall of the saw blade 14. At this time, the saw blade 14 is in an idle state during the reset process. As the saw blade 14 rotates continuously, the scrapers 26 can scrape off the large pieces of debris adhering to the surface of the saw blade 14 to achieve preliminary chip removal. Some of the scraped debris will fall off directly, while the other part will stick to and accumulate on one side of the scraper 26.

[0031] As the two vertical plates 16 continue to move towards the saw blade 14 and remain centered, the scraper 26 is stopped by the saw blade 14. Meanwhile, the vertical plates 16 continue to move the moving plate 17 closer to the saw blade 14. At this point, the scraper 26 slides a short distance on the vertical plates 16. This movement of the scraper 26 drives the meshing gears to rotate. As the cam 24 rotates with the gears via the shaft 25, it pushes the moving plate 17 to slide on the vertical plates 16 until the rotating roller 29 on the moving plate 17 gradually contacts the side wall of the saw blade 14. The rotation of the saw blade 14 drives the rotating roller 29 to rotate. When the reciprocating screw 27 rotates at high speed with the rotating roller 29, it drives the slider 30 to move vertically. The reciprocating motion of the slider 30 drives the piston plate 31 to slide back and forth within the sealed box 28. When the piston plate 31 moves towards the inside of the sealed box 28, it can compress the gas inside the sealed box 28, generating a certain pressure of gas that is rapidly ejected from the jet nozzle 38 at the lower end of the sealed box 28, forming a stable pulse airflow that directly acts on the tooth groove of the saw blade 14. This can loosen and blow off the fine, oily, sludge-like debris and the tightly stuck, curled long chips that are adhering to the inside of the tooth groove. When the piston plate 31 moves in the opposite direction under the action of the slider 30, the outside air is replenished into the sealed box 28 through the jet nozzle 38, waiting for the next pulse jet. This cycle continues, and with the continuous rotation of the saw blade 14, the deep chip removal treatment of all tooth grooves can be completed.

[0032] Simultaneously, as the mounting plate 13, protective cover 15, and saw blade 14 move and move away from the metal parts, the water spray pipe 6 is again limited by the crossbar 5 and flips from a vertical state to an inclined state. At this time, the water spray nozzle of the water spray pipe 6 faces the saw blade 14, and the sprayed cutting fluid can flush the saw blade 14 and scraper 26. Combined with the pulse airflow, it can further remove the fine debris remaining in the tooth gaps, improve the chip removal effect, and also wash off the debris attached to one side of the scraper 26, which can clean the scraper 26 and cool the saw blade 14 over a larger area.

[0033] Since the magnetic plate 18 is located on one side of the saw blade 14, the centrifugal force generated when the saw blade 14 spins freely after detaching from the metal part can separate some of the attached debris. At the same time, the magnetic plate 18 can also adsorb the debris in the tooth groove of the saw blade 14, further improving the chip removal efficiency and preventing small metal debris from re-adhering to the already cleaned saw blade surface.

[0034] As the cut metal parts slide down the pallet 8, they push the baffle 9 and cause the rotating rod 40 to rotate inside the cylinder 10. The fan blade 41 moves inside the cylinder 10 as the rotating rod 40 rotates. The fan blade 41 moves slowly due to the resistance of the hydraulic oil inside the cylinder 10. Therefore, the baffle 9 rotates slowly with the rotating rod 40, and the metal parts slide down the pallet 8 slowly. When the metal parts are removed from the pallet 8, they fall onto the feed plate 11 and continue to slide down.

[0035] After the metal part is removed from the support plate 8, the volume of the sealed cavity inside the support plate 8 is restored. At this time, the vertical plate 16 is reset and moved under the pull of the first spring 22, and the gas in the concave box 12 is squeezed by the square plate 32. The gas in the concave box 12 flows back to the sealed cavity through the connecting pipe 19. The air pressure in the concave box 12 is restored. The first spring 22 pulls the two vertical plates 16 to move in opposite directions, causing the separation component to be completely separated from the saw blade 14. This will not affect the next normal cutting operation of the saw blade 14. The entire chip removal process is completed automatically during the equipment interval between the completion of the cutting process and the start of the feeding process. There is no need for manual shutdown operation. This will not disrupt the processing rhythm of the automated production line and ensure production capacity. It will also completely eliminate the safety hazards of iron filings flying and mechanical scratches during manual chip removal. At the same time, through the combination of multiple chip removal steps such as scraping, pulse jetting, cutting fluid flushing, and magnetic attraction, the oily sludge-like debris in the saw blade tooth groove and equipment dead corners can be removed.

[0036] As the rotating rod 40 slowly resets under the action of the second torsion spring, the baffle 9 will not cause the pallet 8 to shake significantly, ensuring the stability of the feeding process. At the same time, as the rotating rod 40 rotates, the support rod 39 will push the push plate 20 to slide on the L-shaped plate 34 and the magnetic plate 18. During the movement of the push plate 20, it can scrape off the metal debris adsorbed on the surface of the magnetic plate 18. When the end of the push plate 20 moves to the end of the L-shaped plate 34, the push plate 20 can push the metal debris onto the L-shaped plate 34 and away from the magnetic plate 18. At this time, the magnetic plate 18 no longer has an adsorption force on this part of the metal debris, and the debris will fall off under its own gravity, achieving the effect of intermittent cleaning of the magnetic plate 18. This avoids the magnetic plate 18 surface from accumulating too much debris, which would reduce its adsorption capacity and ensure that the adsorption effect of the magnetic plate 18 can be maintained stably for a long time. After the rotating rod 40 slowly resets under the action of the second torsion spring, the push plate 20 also slowly resets under the action of the horizontal spring, preventing large collisions that would cause equipment vibration and ensuring the overall operational stability of the equipment.

[0037] When the two vertical plates 16 move laterally, multiple vibrating plates 37 on the sidewalls of the vertical plates 16 sequentially contact the impact plates 36 on the support plate 35. As the vertical plates 16 move laterally, the sidewalls of the vibrating plates 37 push the impact plates 36 one by one, causing the impact plates 36 to compress the third spring 33 and deform. When the vibrating plates 37 move away from their current position, the impact plates 36 quickly reset under the elastic force of the third spring 33 and impact the next adjacent vibrating plate 37, thereby generating continuous high-frequency vibration of the entire vertical plate 16. This, in turn, drives the scraper 26 and the moving plate 17 installed on the vertical plate to vibrate synchronously. This high-frequency vibration can shake off the oily sludge-like debris adhering to and accumulating on the surface of the scraper 26, avoiding excessive debris accumulation on the surface of the scraper 26 and reducing the scraping effect on large debris on the surface of the saw blade 14.
