Description

Technical Field

[0001] This invention relates to the field of metal forging processing technology, specifically to a burr-removing device for metal forging processing. Background Technology

[0002] In the metal forging process, burr removal is a crucial step in ensuring dimensional accuracy and surface quality. Currently, the industry commonly uses belt grinding or wheel grinding to remove flash and burrs from the edges of forgings, with belt grinding being widely used due to its flexibility and high efficiency. However, in most existing belt grinding devices, the grinding belt is typically supported by a fixed guide wheel or tension wheel, making it difficult to adjust the contact angle and pressure between the grinding belt and the workpiece surface in real time according to changes in the workpiece's shape. When the forging has a large tilt angle, curved surface, or irregular contour, the fixed belt... The guide structure cannot ensure that the grinding belt fits tightly against the workpiece surface, resulting in uneven burr removal and the occurrence of local over-grinding or under-grinding, which affects the processing quality. In addition, the abrasive belt will loosen after running at high speed for a long time. Traditional devices rely on manual periodic adjustment of the tension wheel position, which not only increases auxiliary time but also makes it difficult to ensure constant tension during grinding, further reducing grinding stability. Although some equipment attempts to add an elastic clamping mechanism, the structure is often complex and cannot simultaneously achieve active deformation control and automatic tension compensation of the inner support plate of the grinding belt.

[0003] For example, the Chinese invention patent (application number: CN202411370151.6) discloses a "grinding device for metal forgings," which states that metal is a substance with properties such as luster (i.e., strong reflection of visible light), ductility, and good electrical and thermal conductivity. The vast majority of metallic elements on Earth exist in nature in a combined state. This is because most metals are chemically reactive, and only a very few, such as gold and silver, exist in a free state. Metals are widely found in nature and are extremely common in daily life. They are a very important and widely used type of material in modern industry. During the processing and grinding of metal workpieces, workers often need to grind multiple sides of the workpieces, usually using grinding devices. Utility model announcement CN207448148U specifically discloses a grinding device for non-ferrous metal forgings that can achieve double-sided grinding. Through the cooperation of a first motor, a first rotating shaft, a first grinding disc, a second motor, a first gear, a second gear, a second rotating shaft, a second grinding disc, a first electric push rod, a second electric push rod, a connecting plate, a third electric push rod, and a pressing plate, the device achieves the purpose of double-sided grinding of metal workpieces, thus facilitating the work of workers. This device is only suitable for double-sided grinding of short forgings. However, if the forging is long, it cannot effectively grind the outer surface of the forging. Furthermore, the device has a grinding blind spot in the area where the forging is clamped and fixed, requiring secondary processing by the user. Therefore, it cannot significantly improve the efficiency of the device in grinding forgings. The aforementioned patent can corroborate the defects of the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a burr removal device for metal forging processing, to solve the problems mentioned in the background art. However, in most existing belt grinding devices, the grinding belt is usually supported by a fixed guide wheel or tension wheel. The contact angle and pressure between the grinding belt and the workpiece surface are difficult to adjust in real time according to changes in the workpiece shape. When the forging side has a large tilt angle, curved surface, or irregular contour, the fixed guide structure cannot make the grinding belt fit tightly against the workpiece surface, resulting in uneven burr removal and easy occurrence of local over-grinding or under-grinding, affecting the processing quality. In addition, the abrasive belt will loosen after long-term high-speed operation. Traditional devices rely on manual periodic adjustment of the tension wheel position, which not only increases the auxiliary time, but also makes it difficult to ensure constant tension during grinding, further reducing the problem of grinding stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes spaced support frames, with a second aluminum profile fixedly installed on the top of two sets of support frames, and a slide rail fixedly installed on the bottom of the two sets of support frames. A side plate is fixedly installed on the outer side of one set of support frames, and a drive motor is fixedly installed on the outer side of the side plate. A synchronous pulley is fixedly installed at the output end of the drive motor, and a grinding belt is provided on the outer side of the synchronous pulley. Adaptive components are spaced apart on the side of the two sets of support frames perpendicular to the drive motor, and the adaptive components include mounting discs. First guide shafts are symmetrically installed on the side of the mounting discs away from the support frames, and the two sets of first guide shafts contact the inner side of the grinding belt.

[0006] Preferably, pads are symmetrically arranged between the two sets of first guide shafts, and the outer side of the pads is in contact with the inner side of the grinding belt. The pads are made of polyurethane elastic material. The outer side of both sets of pads is provided with a side groove, which makes it easier for the pads to bend and deform. A connecting rod is installed at one end of the inner side of both sets of pads that are close to each other, and an inclined second cylinder is sleeved on the outer side of the connecting rod. The other end of the second cylinder is rotatably sleeved with a T-shaped shaft.

[0007] Preferably, a side connecting plate is fixedly installed at the end of the two sets of T-shaped shafts away from the mounting disk, and right-angle shafts are symmetrically spaced at the upper and lower ends of the side connecting plate.

[0008] Preferably, a sleeve block is rotatably sleeved on the outer side of one end of the right-angle shaft, and the sleeve block is fixedly connected to the inner side of the pad. A limit rod is rotatably sleeved on the other end of the outer side of the right-angle shaft. A first fastening nut and a second fastening nut are threaded to both ends of the limit rod, and one end of the limit rod extends through the mounting disc to the other side.

[0009] Preferably, a limiting shaft is rotatably connected at the center of the outer side of the mounting disc away from the pad, and a first aluminum profile is fixedly installed at the end of the limiting shaft near the support frame, and the first aluminum profile is located on top of the second aluminum profile.

[0010] Preferably, an adjustment plate is fixedly installed on the side wall of the second aluminum profile, and the adjustment plate extends to one side of the first aluminum profile. Fastening bolts are symmetrically inserted through the top of the outer side of the adjustment plate, and the fastening bolts are threadedly connected to the first aluminum profile.

[0011] By setting fastening bolts to be threadedly connected to the first aluminum profile, it is easy to change the installation position of the first aluminum profile, and thus easy to change the installation position of the mounting disc and the entire adaptive adjustment assembly, thereby adapting to different usage environments.

[0012] Preferably, an extension shaft is fixedly installed at the center of the outer side of the adjustment plate, and a first set of shafts and a second set of shafts are vertically arranged on the outer side of the extension shaft. A right-angle telescopic shaft is sleeved through the end of the first set of shafts away from the extension shaft, and one end of the right-angle telescopic shaft is fixedly connected to the outer side of the side connecting plate. The end of the right-angle telescopic shaft located inside the first set of shafts is sealed to the first set of shafts.

[0013] Preferably, the top of the second shaft is fitted with an outwardly extending movable shaft, one end of the movable shaft located inside the second shaft is sealed and fitted, the top of the movable shaft is fixedly mounted with an mounting block, and the side wall of the mounting block is rotatably connected to a second guide shaft, the outer side of the second guide shaft being in contact with the inner side of the grinding belt.

[0014] Preferably, a connecting groove is provided on the inner side of the extension shaft, and an air groove is provided at the end of the inner cavity of the first set shaft and the second set shaft near the extension shaft. The two ends of the connecting groove are respectively connected to the first set shaft and the second set shaft through the air groove. A return spring is fixedly installed at the end of the movable shaft and the right-angle telescopic shaft that are close to each other, and the other end of the return spring is fixedly connected to the inner side of the first set shaft and the second set shaft respectively.

[0015] Preferably, an extension plate is fixedly installed on the side of the two sets of support frames away from the grinding belt, and an inclined first cylinder is sleeved on the bottom of the extension plate, and a base plate is rotatably sleeved on the bottom of several first cylinders.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Adaptive components are spaced apart on one side of the two sets of support frames perpendicular to the drive motor, including a mounting disc and two sets of first guide shafts symmetrically mounted on its outer side; when the grinding belt contacts the side of the forging with a large tilt angle or irregular curved surface, the grinding belt will be subjected to uneven extrusion force, which is transmitted to the two sets of pads; since the pads are made of polyurethane elastic material and have side grooves on the outer side, the pads can bend and deform; at the same time, the inner side of the pads is rotatably connected to the right-angle shaft through a sleeve block, so that the pads can swing around the right-angle shaft; in conjunction with the inclined second cylinder, one end of which is connected to the pad through a connecting rod, and the other end is rotatably sleeved to the T-shaped shaft and fixed to the side connecting plate, the extension and retraction of the second cylinder can actively push the pad to change the angle, so that the inner side of the grinding belt always closely fits the complex outer contour of the forging.

[0017] 2. An extension shaft is fixed at the center of the outer side of the adjusting plate. A first set of shafts and a second set of shafts are vertically mounted on the extension shaft, and the two sets are interconnected through a connecting groove on the inner side of the extension shaft. A right-angle telescopic shaft is sleeved inside the first set of shafts and is fixedly connected to the side connecting plate. A movable shaft is sleeved inside the second set of shafts, and a second guide shaft is rotatably connected to the top of the movable shaft via a mounting block. The outer side of the second guide shaft contacts the inner side of the grinding belt. When the grinding belt becomes loose due to long-term operation or is compressed by forgings, the side connecting plate will drive the right-angle telescopic shaft to move inwards towards the first set of shafts, compressing the internal return spring and compressing the sealed gas. Due to the connection effect of the connecting groove, the gas pressure will push the movable shaft inside the second set of shafts outwards, thereby driving the second guide shaft to move outwards and automatically tensioning the grinding belt. Conversely, when the compressive force decreases, the return spring resets all components. This structure can achieve dynamic tension compensation without external sensors or power sources, ensuring that the grinding belt is always at the optimal working tension.

[0018] 3. Uniform reciprocating grinding is achieved through guide rails, further improving surface quality; The bottom of the two sets of support frames is fixedly equipped with guide rails, which can be connected to an external linear drive module to drive the entire grinding device to reciprocate along the surface of the forging; Combined with the above-mentioned adaptive fitting and automatic tensioning functions, the grinding belt can maintain stable and uniform grinding pressure during the reciprocating motion, avoiding the vibration and grinding marks commonly found in manual operation or fixed feed methods, and finally obtaining a flat and smooth edge of the forging.

[0021] 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.

[0022] This invention provides a technical solution: such as Figures 1-8 The device shown is a burr-removing device for metal forging processing, including spaced support frames 1. A second aluminum profile 35 is fixedly installed on the top of two sets of support frames 1, and a slide rail 34 is fixedly installed on the bottom of the two sets of support frames 1. A side plate 5 is fixedly installed on the outer side of one set of support frames 1, and a drive motor 6 is fixedly installed on the outer side of the side plate 5. A synchronous wheel 8 is fixedly installed on the output end of the drive motor 6. A grinding belt 9 is provided on the outer side of the synchronous wheel 8. Adaptive components are spaced apart on the side of the two sets of support frames 1 perpendicular to the drive motor 6. The adaptive components include a mounting disc 21. A first guide shaft 22 is symmetrically installed on the side of the mounting disc 21 away from the support frame 1. The two sets of first guide shafts 22 are in contact with the inner side of the grinding belt 9.

[0023] The slide rail 34 facilitates the reciprocating sliding of the device, thereby making it convenient to reciprocate grinding of the surface of the metal forging.

[0024] The flexible bonding system, consisting of a pad 31, a second cylinder 25, and a right-angle shaft 27, along with a pneumatic linkage tensioning system composed of a first set of shafts 13, a second set of shafts 18, a connecting groove 17, and a return spring 15, in conjunction with an adjusting plate 10, a first cylinder 3, and a slide rail 34, comprehensively solves the pain points of the existing technology from four dimensions: bonding performance, tension stability, position and angle adjustability, and motion uniformity, significantly improving the automation level and processing quality of burr grinding of metal forgings.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, pads 31 are symmetrically arranged between the two sets of first guide shafts 22, and the outer side of the pads 31 is in contact with the inner side of the grinding belt 9. The pads 31 are made of polyurethane elastic material. The outer side of both sets of pads 31 is provided with a side groove 33. The side groove 33 makes it easier for the pads 31 to bend and deform. The inner side of the two sets of pads 31 is provided with a connecting rod 26 at one end that is close to each other. The outer side of the connecting rod 26 is sleeved with an inclined second cylinder 25. The other end of the second cylinder 25 is rotatably sleeved with a T-shaped shaft 24.

[0026] Furthermore, a side connecting plate 23 is fixedly installed at the end of the two sets of T-shaped shafts 24 away from the mounting disk 21, and right-angle shafts 27 are symmetrically spaced at the upper and lower ends of the side connecting plate 23.

[0027] Furthermore, a sleeve block 32 is rotatably sleeved on the outer side of one end of the right-angle shaft 27, and the sleeve block 32 is fixedly connected to the inner side of the pad 31. A limit rod 29 is rotatably sleeved on the other end of the outer side of the right-angle shaft 27. The two ends of the limit rod 29 are respectively threaded with a first fastening nut 28 and a second fastening nut 30. One end of the limit rod 29 extends through the mounting disc 21 to the other side.

[0028] Furthermore, a limiting shaft 20 is rotatably connected at the center of the outer side of the mounting disc 21 away from the pad 31, and a first aluminum profile 7 is fixedly installed at the end of the limiting shaft 20 near the support frame 1, and the first aluminum profile 7 is located on top of the second aluminum profile 35.

[0029] The drive motor 6, through the synchronous wheel 8 and grinding belt 9 installed at its output end, facilitates the grinding of the outer surface of the metal forging. During the grinding process, the pressure between the grinding belt 9 and the metal forging forces the pad 31 to deform, and also allows the pad 31 to rotate around the right-angle axis 27 in conjunction with the sleeve block 32, thereby better fitting the outer surface of the metal forging. At the same time, by setting the second cylinder 25 on the outer side of the two sets of pads 31, the position of the pad 31 can be actively changed by the extension and retraction of the second cylinder 25, so as to avoid the metal forging being too long and causing the metal forging to shift during long-term use, resulting in insufficient edge grinding.

[0030] Uniform reciprocating grinding is achieved by guiding the slide rail 34, further improving the surface quality; the bottom of the two sets of support frames 1 are fixedly installed with slide rail 34, which can be connected to an external linear drive module to drive the entire grinding device to reciprocate along the surface of the forging; combined with the above-mentioned adaptive fitting and automatic tensioning functions, the grinding belt 9 can maintain stable and uniform grinding pressure during the reciprocating motion, avoiding the vibration and grinding marks commonly found in manual operation or fixed feed methods, and finally obtaining a flat and smooth edge of the forging.

[0031] Reference Figure 5 , Figure 7 and Figure 8 As shown, an adjustment plate 10 is fixedly installed on the side wall of the second aluminum profile 35, and the adjustment plate 10 extends to one side of the first aluminum profile 7. Fastening bolts 11 are symmetrically inserted through the top of the outer side of the adjustment plate 10, and the fastening bolts 11 are threadedly connected to the first aluminum profile 7.

[0032] By setting the fastening bolt 11 to be threadedly connected to the first aluminum profile 7, it is easy to change the installation position of the first aluminum profile 7, and thus it is easy to change the installation position of the mounting disc 21 and the entire adaptive adjustment assembly, thereby adapting to different usage environments.

[0033] Furthermore, an extension shaft 12 is fixedly installed at the center of the outer side of the adjusting plate 10, and a first set of shafts 13 and a second set of shafts 18 are vertically arranged on the outer side of the extension shaft 12. A right-angle telescopic shaft 14 is sleeved through the end of the first set of shafts 13 away from the extension shaft 12, and one end of the right-angle telescopic shaft 14 is fixedly connected to the outer side of the side connecting plate 23. The end of the right-angle telescopic shaft 14 located inside the first set of shafts 13 is sealed to the first set of shafts 13.

[0034] Furthermore, the top of the second shaft 18 is fitted with an outwardly extending movable shaft 19, one end of the movable shaft 19 located inside the second shaft 18 is sealed and fitted, and the top of the movable shaft 19 is fixedly mounted with a mounting block 36. The side wall of the mounting block 36 is rotatably connected to a second guide shaft 37, and the outer side of the second guide shaft 37 is in contact with the inner side of the grinding belt 9.

[0035] Adaptive components are spaced apart on one side of the two sets of support frames 1 perpendicular to the drive motor 6, including a mounting disc 21 and two sets of first guide shafts 22 symmetrically mounted on its outer side; when the grinding belt 9 contacts the side of the forging with a large tilt angle or irregular curved surface, the grinding belt 9 will be subjected to uneven extrusion pressure, which is transmitted to the two sets of pads 31; since the pads 31 are made of polyurethane elastic material and have side grooves 33 on the outer side, the pads 31 can bend and deform; at the same time, the inner side of the pads 31 is rotatably connected to the right angle shaft 27 through the sleeve block 32, so that the pads 31 can swing around the right angle shaft 27; with the inclined second cylinder 25, one end of which is connected to the pads 31 through the connecting rod 26, and the other end is rotatably sleeved on the T-shaped shaft 24 and fixed on the side connecting plate 23, the extension and retraction of the second cylinder 25 can actively push the pads 31 to change angle, so that the inner side of the grinding belt 9 always closely fits the complex outer contour of the forging.

[0036] Furthermore, a connecting groove 17 is provided on the inner side of the extension shaft 12, and an air groove 16 is provided at the end of the inner cavity of the first set of shafts 13 and the second set of shafts 18 near the extension shaft 12. The two ends of the connecting groove 17 are respectively connected to the first set of shafts 13 and the second set of shafts 18 through the air groove 16. A return spring 15 is fixedly installed at the end of the movable shaft 19 and the right-angle telescopic shaft 14 that are close to each other. The other end of the return spring 15 is fixedly connected to the inner side of the first set of shafts 13 and the second set of shafts 18 respectively.

[0037] During the grinding process, if the metal forging has an excessively large side inclination angle, as the grinding continues, the metal forging will continuously compress the grinding belt 9 and the symmetrically arranged pads 31 on the inner side of the grinding belt 9. This compression force is then transmitted to the side connecting plate 23 via the first cylinder 3. At this time, the side connecting plate 23 will synchronously transmit the compression force to the right-angle telescopic shaft 14, causing it to compress the reset spring 15 connected to it. This also compresses the gas inside the first set of shafts 13. Since the first set of shafts 13 and the second set of shafts 18 are connected through the connecting groove 17, when the right-angle telescopic shaft 14 moves inward, the gas conduction will push the movable shaft 19 outward, thereby pushing the mounting block 36 and the second guide shaft 37 outward. This ensures that the grinding belt 9 is always taut, avoiding any impact on the grinding effect.

[0038] An extension shaft 12 is fixed at the center of the outer side of the adjusting plate 10. A first set of shafts 13 and a second set of shafts 18 are vertically arranged on the extension shaft 12, and the two are connected to each other through a connecting groove 17 opened on the inner side of the extension shaft 12. A right-angle telescopic shaft 14 is sleeved inside the first set of shafts 13, and the right-angle telescopic shaft 14 is fixedly connected to the side connecting plate 23. A movable shaft 19 is sleeved inside the second set of shafts 18. The top of the movable shaft 19 is rotatably connected to a second guide shaft 37 through a mounting block 36. The outer side of the second guide shaft 37 contacts the inner side of the grinding belt 9. When the grinding belt 9 becomes loose due to long-term operation... When subjected to forging pressure, the side connecting plate 23 will drive the right-angle telescopic shaft 14 to move into the first set of shafts 13, compressing the internal return spring 15 and squeezing the sealed gas; due to the connection effect of the connecting groove 17, the gas pressure will push the movable shaft 19 in the second set of shafts 18 to extend outward, thereby driving the second guide shaft 37 to move outward and automatically tensioning the grinding belt 9; conversely, when the extrusion pressure decreases, the return spring 15 resets each component; this structure can achieve dynamic tension compensation without external sensors or power sources, ensuring that the grinding belt 9 is always at the optimal working tension.

[0039] Reference Figure 2 As shown, an extension plate 2 is fixedly installed on the side of the two sets of support frames 1 away from the grinding belt 9, and an inclined first cylinder 3 is sleeved on the bottom of the extension plate 2, and a base plate 4 is rotatably sleeved on the bottom of several first cylinders 3.

[0040] The tilted first cylinder 3, in conjunction with the base plate 4, allows for easy adjustment of the grinding tilt angle of the entire device, making it more adaptable to different working environments.
