Description

Technical Field

[0001] This invention relates to the technical field of casting gating and riser cutting, and in particular to an automatic casting gating and riser cutting device. Background Technology

[0002] The gating and riser system is a collective term for the gating system and riser system in the casting process. It is a key structure connecting the mold cavity to the external molten metal source. Their main functions are to smoothly and orderly introduce molten metal into the mold cavity, replenish molten metal during solidification to compensate for shrinkage, assist in venting and slag collection, and ultimately affect the quality of the casting.

[0003] Cutting the gating system and risers is a key post-processing step in casting production. Its purpose is to safely and efficiently separate the gating system and risers (the remaining parts of the gating system and riser system) from the casting body, while ensuring the dimensional accuracy, surface quality and mechanical properties of the casting.

[0004] In order to improve the processing and blanking in the factory casting process, multiple castings are cast on one side of a main frame at the same time. After the casting is completed, there will be a row of gating gates to be cut to separate the castings from the gating gates.

[0005] Chinese patent CN219335948U discloses an automatic cutting device for casting risers and gatings, including a worktable and an L-shaped connecting plate. The top of the worktable has a mounting groove, and a second motor is mounted at the front end of the mounting groove. The output end of the second motor penetrates the inner wall of the mounting groove and is fixedly connected to a bidirectional threaded rod. Two threaded sleeves are threadedly connected to the external threads of the bidirectional threaded rod, and a clamping plate is fixedly connected to the top of each threaded sleeve. The L-shaped connecting plate is located above the worktable, and a collection box is fixedly connected to its top. This invention allows for the rapid clamping and fixing of castings of different sizes, preventing displacement during cutting and greatly improving the flexibility of the device. It also absorbs dust generated during casting cutting, optimizing the working environment and preventing workers from inhaling it, thus protecting their health.

[0006] When cutting the gating gates of castings, the aforementioned related technologies and existing technologies generally involve moving a cutting wheel or cutting blade relative to the fixed casting to gradually cut the rows of gating gates. Furthermore, the cutting is performed from one side of the cutting position, which can cause the separated casting to shift during the rapid separation process, resulting in an uneven cut. Summary of the Invention

[0007] To address the problem that cutting risers and gating gates requires gradual cutting and that force is applied to one side of the riser during cutting, resulting in uneven cut edges, this invention provides an automatic cutting device for casting risers and gating gates.

[0008] The present invention provides an automatic cutting device for casting risers and gatings, which adopts the following technical solution: including a material clamping table.

[0009] A cutting wire assembly is located above a material clamping platform. The cutting wire assembly includes a cutting wire control frame and multiple cutting wire mounting components. Each cutting wire mounting component is connected to the cutting wire control frame. The cutting wire mounting components can be disassembled and fixed, thereby changing their position on the cutting wire control frame. The cutting wire mounting components are equipped with cutting wire ropes.

[0010] A drive control mechanism is connected to the material clamping table and the cutting line control frame.

[0011] It also includes a detection and control module, which consists of a clamping detection and control module, a cutting wire loop detection and control module, and a cutting wire cutting control module. The clamping detection and control module is connected to the material clamping table. Both the cutting wire loop detection and control module and the cutting wire cutting control module are connected to the drive control mechanism. After the clamping detection and control module detects that the material clamping table has clamped the material, it controls the drive control mechanism to drive the cutting wire to approach the clamped casting. The cutting wire loop detection and control module can control the cutting wire control frame to drive the cutting wire mounting assembly to make the lower end of the cutting wire loop loop around the casting riser and gating gate one and a half times. Then, the cutting wire cutting control module can control the drive control mechanism to drive the cutting wire to move up and down through the driving cutting wire control frame to cut the contacted casting riser and gating gate.

[0012] Optionally, the cutting line mounting assembly includes a stand, a winding wheel, and a rope winding assembly. The rope winding assembly is connected to the stand and is located below the winding wheel. The two ends of the cutting line rope are connected to the winding wheel and the rope winding assembly, respectively. The cutting line control frame drives the rope winding assembly to make the cutting line rope wrap around the casting riser and gating gate one and a half times.

[0013] The winding wheel is elastically torsionally connected to the upper end of the upright, and the upright is connected to the cutting line control frame.

[0014] Optionally, the cutting line control frame includes a main frame and a drive frame. The drive frame is connected to the main frame, the main frame is connected to the drive control mechanism, the rope winding assembly is connected to the drive frame, and the upright is sleeved and installed on the outside of the main frame.

[0015] The drive frame drives the rope winding assembly to rotate the lower end of the cutting rope, and the drive control mechanism drives the main frame to move vertically back and forth.

[0016] Optionally, the rope winding assembly includes:

[0017] The winding shaft and the vertical rod are installed perpendicularly. A rope-receiving rod is rotatably installed at one end of the vertical rod away from the winding shaft. The other end of the rope-receiving rod is fixedly installed to the lower end of the cutting rope. The rope-receiving rod is parallel to the winding shaft. The upright frame is rotatably sleeved on the outer surface of the winding shaft.

[0018] It also includes a rope winding gear and a rope winding tooth plate. The rope winding gear meshes with the rope winding tooth plate. The rope winding gear is coaxially fixed with the winding shaft. The rope winding tooth plate is connected to the drive frame. The drive frame drives the rope winding tooth plate to move and mesh with the rope winding gear.

[0019] Optionally, the drive frame is equipped with a clamping tooth plate, and a clamping gear meshes on the upper side of the clamping tooth plate. A grooved sleeve is coaxially installed on the side of the winding wheel near the drive frame. A toothed ring groove is provided on the axial side of the grooved sleeve. An inner plug is coaxially provided on the side of the grooved sleeve away from the winding wheel. The outer ring surface of the inner plug is provided with teeth that cooperate with the toothed ring groove of the grooved sleeve.

[0020] The clamping gear is coaxially mounted with a telescopic shaft. Both ends of the telescopic shaft can extend and retract and rotate synchronously. One end of the telescopic shaft is rotatably connected to the upright frame, and the other end of the telescopic shaft is threadedly connected to the upright frame. The telescopic shaft is coaxially mounted with the inner plug.

[0021] Optionally, the vertical rod is telescopic at both ends, a telescopic transmission assembly is installed inside the winding shaft, and a movable drive assembly is installed on the drive frame. The movable drive assembly drives the two ends of the vertical rod to telescopically extend and retract through the telescopic transmission assembly.

[0022] Optionally, the movable drive assembly includes a movable plate and two adjusting threaded rods. The two ends of the movable plate are respectively threaded onto the outer surfaces of the two adjusting threaded rods. The adjusting threaded rods are rotatably connected to the main frame. When the distance between the movable plate and the drive frame is changed by rotating the adjusting threaded rods, the vertical rod is extended or retracted through the telescopic transmission assembly.

[0023] Optionally, the telescopic transmission assembly includes:

[0024] The device comprises a double-ended inner shaft, an internal gear plate, and an internal gear. The double-ended inner shaft is slidably inserted into the inside of the winding shaft. The two ends of the double-ended inner shaft located inside the winding shaft can rotate relative to each other. One end of the double-ended inner shaft located inside the winding shaft has a through slot that runs vertically through it. The internal gear plate meshes with the internal gear, and the internal gear plate is installed inside the slot.

[0025] It also includes a meshing threaded shaft, which rotates through the outer surface of the winding shaft. The meshing threaded shaft is coaxially installed with the built-in gear, and the telescopic end of the vertical rod away from the winding shaft is threaded onto the outer surface of the meshing threaded shaft.

[0026] Optionally, the tooth groove of the grooved sleeve near the end of the inner plug is flared, and the teeth of the inner plug near the end of the grooved sleeve are set with pointed tips.

[0027] In summary, the present invention has the following beneficial technical effects:

[0028] 1. This invention utilizes the cooperation of multiple sets of cutting wire ropes, multiple sets of cutting wire control frames, and a drive control mechanism. The drive control mechanism drives the cutting wire control frames to position the lower end of the cutting wire rope above the corresponding gating and riser cutting position. The cutting wire control frames drive the cutting wire mounting components to move the lower end of the cutting wire rope around the casting gating and riser one and a half times, causing the lower end of the cutting wire rope to rotate to the position below the gating and riser. The drive control mechanism drives the cutting wire rope to move up and down to cut the contacting casting gating and riser. The cutting wire rope that moves around the gating and riser one and a half times cuts the gating and riser in a circular motion. Multiple cutting wire ropes cut multiple gating and risers simultaneously, and the circular cutting ensures the flatness of the cut end.

[0029] 2. The present invention utilizes the cooperation between the grooved sleeve, the inner plug, and the telescopic shaft. When the telescopic shaft extends, it pushes the grooved sleeve to engage with the inner plug, thereby engaging the clamping gear with the clamping tooth plate and fixing the rotation angle of the winding wheel. This ensures that the cutting wire rope will not loosen when the control frame moves the cutting wire rope up and down, thus stably cutting the gating riser.

[0030] 3. This invention utilizes the cooperation between the built-in toothed plate, the built-in gear, and the movable plate. Depending on the size of the casting, the distance between the movable plate and the winding shaft is adjusted by rotating the adjusting threaded rod. The built-in gear meshes with the built-in toothed plate, causing the adjusting threaded rod to rotate, thereby changing the extension and retraction length of the vertical rod and controlling the radius of the lower end of the cutting wire rope that wraps around the ring.

[0040] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0041] This invention discloses an automatic cutting device for casting gating and riser. For example... Figures 1-3 As shown, it includes a material clamping table 1, a cutting line assembly 2, a drive control mechanism 3, and a detection control module 4.

[0042] Optionally, the material clamping table 1 consists of a material table and two coaxially arranged clamping plates. The two clamping plates are coaxially arranged, and one of the clamping plates can move along the axis of the two clamping plates. During the movement of one clamping plate, the distance between the two clamping plates can be changed, and the casting main frame is placed between the two clamping plates, so that the casting main frame between the two clamping plates is fixed.

[0043] The cutting wire assembly 2 is located on the upper side of the material clamping table 1. The cutting wire assembly 2 includes a cutting wire control frame 21 and multiple cutting wire mounting components 22. Each cutting wire mounting component 22 is connected to the cutting wire control frame 21. The cutting wire mounting component 22 can be disassembled and fixed, thereby changing the position of the installation on the cutting wire control frame 21. The cutting wire mounting component 22 is equipped with a cutting wire rope 23, and the cutting wire mounting component 22 can drive the lower end of the cutting wire rope 23 to rotate.

[0044] In this embodiment, the material of the cutting rope 23 is a high-strength, flexible material with a non-smooth surface, which increases the cutting effect of the cutting rope 23 on the gating and riser when it moves.

[0045] This embodiment of an automatic casting gating and riser cutting device can adapt to different numbers and distances of castings outside the main casting frame by disassembling and fixing the cutting line mounting assembly 22 and changing its installation position and number on the cutting line control frame 21.

[0046] The drive control mechanism 3 is connected to the material clamping table 1 and the cutting line control frame 21.

[0047] In this embodiment, optionally, the drive control mechanism 3 consists of a horizontally telescopic drive cylinder, a vertically telescopic drive cylinder, and a moving platform. The moving platform is slidably connected to the material clamping platform 1. The two ends of the horizontally telescopic drive cylinder are respectively connected to the material clamping platform 1 and the moving platform. When the horizontally telescopic drive cylinder extends and retracts, it controls the moving platform to move relative to the clamped casting.

[0048] The vertical telescopic drive cylinder is connected to the moving table and the cutting line control frame 21 at both ends. When the vertical telescopic drive cylinder extends or retracts, it drives the cutting line control frame 21 to move up and down.

[0049] The detection control module 4 consists of a clamping detection control module 41, a cutting wire rope wrapping detection control module 42, and a cutting wire rope cutting control module 43. The clamping detection control module 41 is connected to the material clamping table 1. The cutting wire rope wrapping detection control module 42 and the cutting wire rope cutting control module 43 are both connected to the drive control mechanism 3. After the clamping detection control module 41 detects that the material clamping table 1 has clamped the material, it controls the drive control mechanism 3 to drive the cutting wire rope 23 to approach the clamped casting. The cutting wire rope wrapping detection control module 42 can control the cutting wire control frame 21 to drive the cutting wire mounting assembly 22 to drive the lower end of the cutting wire rope 23 to wrap around the casting riser and gating port one and a half times. Then, the cutting wire rope cutting control module 43 can control the drive control mechanism 3 to drive the cutting wire rope 23 to move up and down through the driving cutting wire control frame 21 to cut the contacted casting riser and gating port.

[0050] like Figures 4-5 As shown, the cutting wire mounting assembly 22 includes a stand 221, a winding wheel 222, and a rope winding assembly 223. The rope winding assembly 223 is connected to the stand 221 and is located below the winding wheel 222. The two ends of the cutting wire rope 23 are connected to the winding wheel 222 and the rope winding assembly 223, respectively. The cutting wire control frame 21 drives the rope winding assembly 223 to make the cutting wire rope 23 circle around the casting riser and gating gate one and a half times.

[0051] The winding wheel 222 is elastically torsionally connected to the upper end of the upright frame 221, and the upright frame 221 is connected to the cutting line control frame 21.

[0052] Optionally, the elastic connection between the winding wheel 222 and the upright 221 is made by a torsion spring.

[0053] The elastic connection between the winding wheel 222 and the support frame 221 tightens the cutting rope 23 to prevent the slack cutting rope 23 from getting stuck between structures when it moves, thus preventing it from rotating around the riser and gating gate later.

[0054] The cutting line control frame 21 includes a main frame 211 and a drive frame 212. The drive frame 212 is connected to the main frame 211, and the main frame 211 is connected to the drive control mechanism 3. The main frame 211 can move up and down relative to the drive control mechanism 3. The rope winding assembly 223 is connected to the drive frame 212, and the upright 221 is sleeved and installed on the outside of the main frame 211.

[0055] The drive frame 212 drives the rope winding assembly 223 to rotate the lower end of the cutting rope 23, and the drive control mechanism 3 drives the main frame 211 to move vertically back and forth.

[0056] The rope winding assembly 223 includes a winding shaft 2231 and a vertical rod 2232. The winding shaft 2231 and the vertical rod 2232 are installed perpendicularly. A rope receiving rod 2233 is rotatably installed at one end of the vertical rod 2232 away from the winding shaft 2231. The other end of the rope receiving rod 2233 is fixedly installed to the lower end of the cutting rope 23. The rope receiving rod 2233 is parallel to the winding shaft 2231. The support frame 221 is rotatably sleeved on the outer surface of the winding shaft 2231.

[0057] like Figures 6-7 As shown, in this embodiment, the rope winding assembly 223 further includes a rope winding gear 2234 and a rope winding toothed plate 2235. The rope winding gear 2234 meshes with the rope winding toothed plate 2235. The rope winding gear 2234 is coaxially fixed with the winding shaft 2231. The rope winding toothed plate 2235 is connected to the drive frame 212. The drive frame 212 drives the rope winding toothed plate 2235 to move and mesh with the rope winding gear 2234.

[0058] In the initial state, the winding tooth plate 2235 and the winding gear 2234 are disengaged. The elastic connection between the winding wheel 222 and the upright frame 221, by tightening the cutting rope 23, pulls the connecting rod 2233 to the upper side of the winding shaft 2231. When the main frame 211 moves towards the clamped casting, the lower end of the connecting rod 2233 and the cutting rope 23 are located directly above the gate to be cut.

[0059] When the drive frame 212 drives the rope winding tooth plate 2235 to move horizontally and engages with the rope winding gear 2234, it drives the winding shaft 2231 to rotate.

[0060] The drive frame 212 is equipped with a clamping tooth plate 213, and a clamping gear 215 meshes on the upper side of the clamping tooth plate 213. A grooved sleeve 214 is coaxially installed on the side of the winding wheel 222 near the drive frame 212. A toothed ring groove is provided on the axial side of the grooved sleeve 214. An inner plug 216 is coaxially provided on the side of the grooved sleeve 214 away from the winding wheel 222. The outer ring surface of the inner plug 216 is provided with teeth that cooperate with the toothed ring groove of the grooved sleeve 214.

[0061] The clamping gear 215 is coaxially mounted with a telescopic shaft 217. Both ends of the telescopic shaft 217 can extend and rotate synchronously. One end of the telescopic shaft 217 is rotatably connected to the upright frame 221, and the other end of the telescopic shaft 217 is threadedly connected to the upright frame 221. The telescopic shaft 217 is coaxially mounted with the inner plug 216.

[0062] Therefore, when the drive frame 212 drives the clamping tooth plate 213 to move horizontally, the clamping tooth plate 213 meshes with the clamping gear 215 to drive the telescopic shaft 217 to rotate. The telescopic end of the rotating telescopic shaft 217 is threaded with the upright 221, causing the telescopic shaft 217 to gradually extend and insert the inner plug 216 into the groove sleeve 214.

[0063] In this embodiment, the tooth groove of the grooved sleeve 214 near the end of the inner plug 216 is flared, and the teeth of the inner plug 216 near the end of the grooved sleeve 214 are set with sharp points. When the inner plug 216 is close to the grooved sleeve 214, the inner plug 216 with sharp teeth can be easily inserted into the flared tooth groove of the grooved sleeve 214 for mating.

[0064] In the initial state, the grooved sleeve 214 and the inner plug 216 are separated, ensuring that the winding wheel 222, which is elastically connected to the upright 221, can elastically twist to tighten the cutting rope 23.

[0065] The positions of the clamping toothed plate 213 and the winding toothed plate 2235, and the meshing transmission between the clamping toothed plate 213 and the clamping gear 215, and the winding toothed plate 2235 and the winding gear 2234, satisfy the requirement that when the cutting wire rope 23 rotates one and a half times, the inner plug 216 is inserted into the inner side of the groove sleeve 214.

[0066] In this embodiment, the drive frame 212 consists of a frame body and a horizontally telescopic drive cylinder. The frame body is slidably sleeved on the outside of the main frame 211. When the horizontally telescopic drive cylinder extends and retracts, it drives the frame body to move laterally relative to the main frame 211.

[0067] Second embodiment.

[0068] like Figure 8As shown, in this embodiment, the two ends of the vertical rod 2232 are telescopic, a telescopic transmission assembly 5 is installed inside the winding shaft 2231, and a movable drive assembly 6 is installed on the drive frame 212. The movable drive assembly 6 drives the two ends of the vertical rod 2232 to telescopically extend and retract through the telescopic transmission assembly 5.

[0069] The movable drive assembly 6 includes a movable plate 61 and two adjusting threaded rods 62. The two ends of the movable plate 61 are respectively threaded onto the outer surfaces of the two adjusting threaded rods 62. The adjusting threaded rods 62 are rotatably connected to the main frame 211. When the distance between the movable plate 61 and the drive frame 212 is changed by rotating the adjusting threaded rods 62, the vertical rod 2232 is extended or retracted through the telescopic transmission assembly 5.

[0070] The telescopic transmission assembly 5 includes a double-ended inner shaft 51, an internal gear plate 52, and an internal gear 53. The double-ended inner shaft 51 is slidably inserted into the inside of the winding shaft 2231. The inner and outer ends of the double-ended inner shaft 51 can rotate relative to each other. One end of the double-ended inner shaft 51 inside the winding shaft 2231 has a through slot 54. The internal gear plate 52 meshes with the internal gear 53 and is installed inside the slot 54.

[0071] The telescopic transmission assembly 5 also includes a meshing threaded shaft 55, which rotates through the outer surface of the winding shaft 2231. The meshing threaded shaft 55 is coaxially mounted with the built-in gear 53, and the telescopic end of the vertical rod 2232 away from the winding shaft 2231 is threaded onto the outer surface of the meshing threaded shaft 55.

[0072] In this embodiment, when the circumferential cross-sectional length of the casting changes, the longitudinal distance between the movable plate 61 and the main frame 211 is adjusted, causing the double-ended inner shaft 51 to move within the winding shaft 2231, which in turn causes the built-in toothed plate 52 to mesh with the built-in gear 53, and causes the meshing threaded shaft 55 to rotate. The telescopic end of the vertical rod 2232 away from the winding shaft 2231 meshes with the rotating meshing threaded shaft 55, changing the telescopic length of the vertical rod 2232, thereby changing the distance between the lower end of the rope connecting rod 2233 and the cutting rope 23 and the winding shaft 2231, and controlling the circumferential range of the rotation of the lower end of the cutting rope 23.

[0073] In this application, the structures are rotatably mounted with bearings, and the drive telescopic rod can be an electric telescopic rod or a linear drive power component such as a hydraulic cylinder.

[0074] The working principle is as follows: The material clamping table 1 can fix both ends of the casting main frame. Then, according to the position and quantity of the castings on both sides of the casting main frame, the cutting line mounting component 22 is installed at the corresponding position. After the clamping detection control module 41 detects that the material clamping table 1 clamps the material, it controls the drive control mechanism 3 to drive the cutting line rope 23 to approach the clamped casting. The cutting line rope 23 is initially located on the upper side of the casting. The cutting line rope circling detection control module 42 can control the cutting line control frame 21 to drive the cutting line mounting component 22 to drive the lower end of the cutting line rope 23 to circle around the casting riser and gating port one and a half times. The lower end of the cutting line rope 23 is rotated to the lower side of the riser and gating port. Then, the cutting line rope cutting control module 43 can control the drive control mechanism 3 to drive the cutting line rope 23 to move up and down through the drive cutting line control frame 21 to cut the contacting casting riser and gating port. The cutting line rope 23 cuts around the contact position of the riser and gating port during the movement, ensuring the flatness of the cut end face. At the same time, multiple cutting lines 23 cut multiple risers and gating ports simultaneously, improving cutting efficiency.

[0075] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
