Description

Technical Field

[0001] This utility model relates to the field of graphite processing technology, specifically to a high-efficiency shaping device for spherical graphite. Background Technology

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid. It is chemically stable, corrosion-resistant, and does not readily react with acids, alkalis, or other reagents. Natural graphite comes from graphite deposits, but artificial graphite can also be produced from petroleum coke, pitch coke, and other raw materials through a series of processing steps. Graphite can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It can also be used to manufacture crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, arc lamps, and pencil leads.

[0003] According to announcement number CN 221456341 U, a high-efficiency shaping device for spherical graphite includes a shaping table, a controller fixedly installed on one side of the shaping table, a shaping component provided on the top of the shaping table, a dust collection hood fixedly installed on the top of the shaping table, multiple filters fixedly installed on one side of the dust collection hood, a dust collection pipe fixedly installed on one side of the dust collection hood, and a collection box fixedly installed at the bottom of the dust collection pipe, with the collection box located inside the shaping table.

[0004] This device, through the cooperation of a dust extraction hood, filter, collection box, and suction fan, allows the suction fan to collect dust generated during the spherical graphite shaping process into the collection box, ensuring the cleanliness of the shaping table surface. The filter screen removes larger dust particles, preventing blockages in the suction pipes and avoiding inhalation into the lungs of workers, thus improving the practicality of the spherical graphite high-efficiency shaping device. However, this device merely clamps the spherical graphite with clamping plates, without rotating it during clamping, resulting in low shaping efficiency and difficulty in guaranteeing shaping accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a highly efficient shaping device for spherical graphite to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency shaping device for spherical graphite, comprising a base, with supporting legs symmetrically fixedly connected to the bottom of the base, a clamping and rotating mechanism provided on the top of the base, and a shaping mechanism provided on the top of the base near the back.

[0007] The clamping and rotating mechanism includes a fixed frame, which is fixedly connected to the top of the base. A bidirectional lead screw is rotatably connected to the left side of the inner wall of the fixed frame. Limiting rods are symmetrically fixedly connected to the left and right sides of the inner wall of the fixed frame. A first servo motor is fixedly connected to the right side of the fixed frame. Moving plates are symmetrically threaded to the surface of the bidirectional lead screw. A baffle plate is fixedly connected to the top of the fixed frame. A rotating shaft is provided on one side of the moving plate near the top. A clamping head is fixedly connected to one end of the rotating shaft. An L-plate is fixedly connected to the right side of the moving plate near the right end of the surface of the bidirectional lead screw. A second servo motor is fixedly connected to the right side of the L-plate. A first gear is fixedly connected to the surface of the output shaft of the second servo motor. A second gear is fixedly connected to the right end of the rotating shaft surface near the right side above the fixed frame.

[0008] Preferably, the output end of the first servo motor is fixedly connected to the right end of the bidirectional lead screw. The two moving plates have holes on their left sides near the bottom that match the limiting rod. The two moving plates are slidably connected to the surface of the limiting rod through the holes. The limiting rod limits the two moving plates, so that the two moving plates move towards each other as the bidirectional lead screw rotates.

[0009] Preferably, the two movable plates have grooves on their left sides that match the baffle plate, and the two movable plates are slidably connected to the surface of the baffle plate through the grooves. The baffle plate blocks the bidirectional lead screw and the limiting rod, so that the debris that falls off the spherical graphite during the shaping process will not fall on the surface of the bidirectional lead screw and the limiting rod.

[0010] Preferably, the movable plate has a hole on one side near the top that matches the rotating shaft, and the rotating shaft surface passes through and is rotatably connected to the hole, with the first gear meshing with the second gear.

[0011] Preferably, the shaping mechanism includes an L-shaped base, with a hydraulic cylinder fixedly connected to the top of the L-shaped base near the front. A lifting plate is fixedly connected to the output end of the hydraulic cylinder. Guide rods are symmetrically fixedly connected to the top of the lifting plate. Fixed rods are fixedly connected at equal intervals to the bottom of the lifting plate. An arc-shaped plate is fixedly connected to the bottom end of the fixed rod. A shaping blade is fixedly connected to the concave surface of the arc-shaped plate.

[0012] Preferably, the top of the L-shaped seat has a hole near the front that matches the output shaft of the hydraulic cylinder, and the surface of the output shaft of the hydraulic cylinder is penetrated and slidably connected to the hole.

[0013] Preferably, the top of the L-shaped base has holes on the left and right sides near the front, which match the guide rods. The guide rods are slidably connected to the holes through the surface of the guide rods. The two guide rods support the lifting plate, making the lifting plate more stable when it moves up and down.

[0014] Compared with the prior art, this utility model provides a highly efficient shaping device for spherical graphite, which has the following beneficial effects:

[0015] 1. This high-efficiency spherical graphite shaping device uses a first servo motor to drive a bidirectional lead screw, which, combined with the limiting action of a limiting rod, allows two moving plates to move precisely towards each other, thereby achieving stable clamping of the spherical graphite using a clamping head. The first gear on the output shaft of the second servo motor meshes with the second gear on the rotating shaft, driving the spherical graphite to rotate flexibly. This provides a good foundation for subsequent shaping operations, ensuring that the spherical graphite is in the appropriate position and angle during the shaping process, thus improving shaping accuracy and effectiveness.

[0016] 2. This high-efficiency spherical graphite shaping device features a hydraulic cylinder that drives the lifting plate up and down in the shaping mechanism. Guide rods provide stable support, ensuring smooth lifting of the plate. Multiple fixed rods connect the arc-shaped plate and shaping blade, allowing for simultaneous shaping of multiple parts of the spherical graphite. The arc-shaped plate conforms to the curved surface of the spherical graphite, ensuring uniform shaping and effectively improving the shaping quality and precision of the spherical graphite.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency shaping device for spherical graphite, including a base 1, with supporting legs 2 symmetrically fixedly connected to the bottom of the base 1, a clamping and rotating mechanism 3 provided on the top of the base 1, and a shaping mechanism 4 provided on the top of the base 1 near the back.

[0029] The clamping and rotating mechanism 3 includes a fixed frame 31, which is fixedly connected to the top of the base 1. A bidirectional lead screw 32 is rotatably connected to the left side of the inner wall of the fixed frame 31. Limiting rods 33 are symmetrically fixedly connected to the left and right sides of the inner wall of the fixed frame 31. A first servo motor 34 is fixedly connected to the right side of the fixed frame 31. A moving plate 35 is symmetrically threaded to the surface of the bidirectional lead screw 32. A baffle plate 36 is fixedly connected to the top of the fixed frame 31. A rotating shaft 37 is set on one side of the moving plate 35 near the top. A clamping head 38 is fixedly connected to one end of the rotating shaft 37. An L-plate 39 is fixedly connected to the right side of the moving plate 35 near the right end of the surface of the bidirectional lead screw 32. A second servo motor 311 is fixedly connected to the right side of the L-plate 39. A first gear 312 is fixedly connected to the surface of the output shaft of the second servo motor 311. A second gear 313 is fixedly connected to the right end of the surface of the rotating shaft 37 near the right side above the fixed frame 31.

[0030] The output end of the first servo motor 34 is fixedly connected to the right end of the bidirectional lead screw 32. The two moving plates 35 have holes on their left sides near the bottom that match the limiting rod 33. The two moving plates 35 are slidably connected to the surface of the limiting rod 33 through the holes. The limiting rod 33 limits the two moving plates 35, so that the two moving plates 35 move towards each other as the bidirectional lead screw 32 rotates.

[0031] The two movable plates 35 have grooves on their left sides that match the baffle plate 36, and the two movable plates 35 are slidably connected to the surface of the baffle plate 36 through the grooves. The baffle plate 36 blocks the bidirectional lead screw 32 and the limiting rod 33, so that the debris that falls off the spherical graphite during the shaping process will not fall on the surface of the bidirectional lead screw 32 and the limiting rod 33.

[0032] The movable plate 35 has a hole on one side near the top that matches the rotating shaft 37, and the rotating shaft 37 passes through and is rotatably connected to the hole, with the first gear 312 meshing with the second gear 313.

[0033] Example 2

[0034] Please see Figure 4-5 Furthermore, based on Example 1, a shaping mechanism 4 was obtained.

[0035] The shaping mechanism 4 includes an L-shaped base 41. A hydraulic cylinder 42 is fixedly connected to the top of the L-shaped base 41 near the front. A lifting plate 43 is fixedly connected to the output end of the hydraulic cylinder 42. Guide rods 44 are fixedly connected to the top of the lifting plate 43 symmetrically on the left and right. Fixed rods 45 are fixedly connected to the bottom of the lifting plate 43 at equal intervals. An arc-shaped plate 46 is fixedly connected to the bottom end of the fixed rod 45. A shaping blade 47 is fixedly connected to the concave surface of the arc-shaped plate 46.

[0036] The top of L-shaped base 41 near the front has a hole that matches the output shaft of hydraulic cylinder 42, and the surface of the output shaft of hydraulic cylinder 42 is penetrated and slidably connected to the hole.

[0037] The top of L-shaped base 41 has holes on the left and right sides near the front that match the guide rods 44. The guide rods 44 are connected to the holes through the surface and slide up and down. The two guide rods 44 support the lifting plate 43, making the lifting plate 43 more stable when it moves up and down.

[0038] In actual operation, when this device is used, the first servo motor 34 starts working after the device is started. Since the output end of the first servo motor 34 is fixedly connected to the right end of the bidirectional lead screw 32, when the first servo motor 34 runs, it will drive the bidirectional lead screw 32 to rotate on the left side of the inner wall of the fixed frame 31. Limiting rods 33 are symmetrically fixed on the left and right sides of the inner wall of the fixed frame 31. The two moving plates 35 have holes on the left side near the bottom that match the limiting rods 33, and are slidably connected to the surface of the limiting rods 33 through these holes. During the rotation of the bidirectional lead screw 32, the two moving plates 35 will move towards each other due to the limiting effect of the limiting rods 33. As the moving plates 35 approach each other, the rotating shaft 37 and the clamping head 38 at one end of the rotating shaft 37 located near the top of one side of the moving plate 35 will also move accordingly, ultimately achieving stable clamping of the spherical graphite. After clamping is completed, the second servo motor 311 fixed on the L-plate 39 near the right side of the right moving plate 35 starts. A first gear 312 is fixedly connected to the output shaft surface of the second servo motor 311, while a second gear 313 is fixedly connected to the right end of the rotating shaft 37 near the right side of the upper part of the fixing frame 31, with the first gear 312 meshing with the second gear 313. Therefore, when the second servo motor 311 operates, it drives the rotating shaft 37 to rotate through the meshing transmission of the first gear 312 and the second gear 313, thereby causing the clamped spherical graphite to rotate, preparing for subsequent shaping operations. While the spherical graphite rotates, the shaping mechanism 4 begins to work. A hydraulic cylinder 42 is fixedly connected to the top of the L-shaped base 41 near the front, and the output end of the hydraulic cylinder 42 is fixedly connected to the lifting plate 43. When the hydraulic cylinder 42 is activated, its output shaft slides up and down within a hole on the top of the L-shaped base 41 near the front, matching the output shaft of the hydraulic cylinder 42. This drives the lifting plate 43 to move up and down. Guide rods 44 are symmetrically fixed to the top of the lifting plate 43. Holes matching the guide rods 44 are opened on the left and right sides of the top of the L-shaped base 41 near the front, and the guide rods 44 slide through and are connected to the holes. During the up-and-down movement of the lifting plate 43, the guide rods 44 provide good support, ensuring the smooth movement of the lifting plate 43 and preventing it from swaying or shifting. Fixed rods 45 are fixedly connected at equal intervals to the bottom of the lifting plate 43. An arc-shaped plate 46 is fixedly connected to the bottom end of the fixed rods 45, and a shaping blade 47 is fixedly connected to the concave surface of the arc-shaped plate 46. As the lifting plate 43 descends, the arc-shaped plate 46 and the shaping blade 47 also descend, and the shaping blade 47 performs a shaping operation on the rotating spherical graphite surface. With precise control of the hydraulic cylinder 42, the surface of spherical graphite can be shaped at different locations, meeting the shaping needs of spherical graphite with different specifications and requirements. After shaping, the hydraulic cylinder 42 drives the lifting plate 43 to rise, and the shaping blade 47 leaves the spherical graphite, completing one shaping process.
