Detailed Implementation

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] One preferred embodiment of this application, such as Figures 1 to 7As shown, a centrifugal casting machine includes: a support plate 1, and further includes: a bracket 10, a roller 11, a drive assembly, a cover plate assembly, a support assembly, and a buffer assembly; there are two brackets 10, which are respectively fixedly installed at both ends of the top of the support plate 1; the two ends of the outer circumference of the roller 11 are rotatably installed on the inner circumference of the two brackets 10; the drive assembly is installed on one side of the top of the support plate 1 to drive the roller 11 to rotate; there are two sets of cover plate assemblies, which are respectively disposed at both ends of the roller 11 to seal and cover both ends of the roller 11; the support assembly is installed at one end of the top of the support plate 1 to support one of the cover plate assemblies; the buffer assembly is disposed between the two brackets 10 to buffer the vibration of the two brackets 10.

[0028] First, fix the support plate 1 in the designated working area, ensuring that the two brackets 10 are firmly installed at both ends of the top of the support plate 1 to provide basic support. Then, use the support assembly to position and support one of the cover plate assemblies. Install the two cover plate assemblies to both ends of the roller 11 to complete the sealing and covering of both ends of the roller 11. Inject liquid metal into the roller 11 through the cover plate assembly. Then, start the drive assembly installed on one side of the top of the support plate 1 to drive the roller 11 to rotate at high speed around the inner circumference of the two brackets 10. During the rotation, the buffer assembly works synchronously to buffer and offset the vibration generated by the two brackets 10. After the centrifugal casting operation is completed, turn off the drive assembly and loosen the sealing state of the cover plate assembly, and the material can be taken out. This achieves automatic opening and closing of the cover plate while positioning and sealing the roller, which reduces the labor intensity of manual labor and is easy to operate.

[0029] Further reference Figures 1-6The cover plate assembly includes: cover plate one 201, cover plate two 202, and limiting components. Two cover plates one 201 are vertically disposed at both ends of the roller 11, and two cover plates two 202 are disposed at the ends of the two cover plates one 201 that are close to each other. Both cover plates one 201 and cover plates two 202 are annularly arranged, and the diameter of the outer circle of cover plate two 202 is adapted to the diameter of the inner circumference of the roller 11. Two sets of limiting components are respectively installed at the ends of the two cover plates two 202 that are close to each other. The support assembly includes: Mounting plate 1 203, gantry frame 204, two mounting slots 1 205, and two mounting slots 206 are provided. Mounting plate 1 203 is vertically fixed to one side of the top end of support plate 1. Gantry frame 204 is fixedly fixed to one side of the top end of support plate 1. Two mounting slots 1 205 are fixedly fixed to the top and bottom of one side of mounting plate 1 203, respectively. One mounting slot 206 is fixedly fixed between the top of one side of mounting plate 1 203 and gantry frame 204, and the other mounting slot 206 is fixedly fixed to one side of the top end of support plate 1. Mounting plate 207 is fixedly installed on one side of cover plate 1 201. Support rods 1 208 are vertically fixedly installed on the top and bottom of mounting plate 207. The two support rods 1 208 are slidably installed in the two mounting slots 1 205 via sliding components 1. Support rods 209 are fixedly installed on the top and bottom of cover plate 1 201. The two support rods 209 are slidably installed in the two mounting slots 1 205 via sliding components 2. Inside the mounting plate 206, an electric telescopic rod 2010 is hinged to the top and bottom of one end of the mounting plate 203. The end of the electric telescopic rod 2010 away from the mounting plate 203 is hinged to the top and bottom of the end of the cover plate 201 away from the roller 11, respectively. The mounting plate 206 is divided into a straight section and an arc section. The straight section of the mounting plate 206 has the same dimensions as the mounting plate 205. The center of the arc section of the mounting plate 206 is coaxially set with the support rod 208.

[0030] The electric telescopic rod 2010 extends, and its end away from the mounting plate 203 pushes the cover plate 201 towards the roller 11 to close it. At this time, the support rods 209 at the top and bottom of the cover plate 201 slide along the arc segment of the mounting groove 206 via the sliding assembly 2. Since the center of the arc segment of the mounting groove 206 is coaxial with the support rod 208, the movement trajectory is accurate. Then, it transitions to sliding in a straight section. At the same time, the support rods 208 at the top and bottom of the mounting plate 207 on one side of the cover plate 201 slide in the corresponding mounting groove 205 via the sliding assembly 1. The support rods 208 rotate first, and after the support rods 209 enter the straight section, the support rods 208 slide synchronously. The straight section of the mounting groove 206 is the same size as the mounting groove 205 and works together until the cover plate 202 at one end of the cover plate 201 is tightly attached to the inner circumference of the roller 11, and the cover plate 202 at one end of the cover plate 201 is close to each other. The limiting components are simultaneously positioned to seal one end of the roller 11, while the cover plate assembly at the other end is fixed with screws and other parts. No manual disassembly is required during centrifugal casting. Liquid metal is injected into the roller 11 through cover plate 1 201 and cover plate 2 202. After centrifugal operation is completed, the electric telescopic rod 2010 is retracted, causing cover plate 1 201, cover plate 2 202, and the limiting components to move away from the roller 11. Support rod 2 209 first slides in the opposite direction along the straight section of mounting groove plate 2 206 to the arc section. At this time, support rod 1 208 is simultaneously reset along mounting groove plate 1 205. Then, support rod 2 209 slides within the arc section, rotating around support rod 1 208, releasing the sealing state of the roller 11 and allowing cover plate 1 201 to be fully opened. This does not affect the subsequent removal of the pipe material poured into the roller 11, achieving automatic opening and closing of the cover plate while simultaneously positioning and sealing the roller. This reduces manual labor intensity and is easy to operate.

[0031] Further reference Figure 6 The limiting component includes: limiting ring one 301 and limiting ring two 302. The two limiting rings one 301 are respectively fixedly installed on the inner edge of the two cover plates two 202 that are close to each other. The two limiting rings two 302 are respectively fixedly installed on the two limiting rings one 301 that are close to each other. Both limiting ring one 301 and limiting ring two 302 are hollow frustum-shaped. The cross-sections of limiting ring one 301 and limiting ring two 302 are inverted V-shaped.

[0032] When the drum 11 begins to rotate, the liquid metal inside will flow towards the cover plates 202 at both ends of the drum 11 under the action of centrifugal force and rotational inertia, and there is a risk of overflowing from the inner circle of the cover plates 202. At this time, the hollow frustum-shaped limiting ring 301, which is fixedly connected to the inner circle edge of the cover plate 202, first contacts the flowing liquid metal. Its inverted V-shaped conical surface guides the flow direction of the liquid metal to the limiting ring 302, which is fixedly connected to it. The limiting ring 302 is also hollow frustum-shaped and forms a continuous inverted V-shaped cross section with the limiting ring 301. Its conical surface further tilts and guides the flow direction of the liquid metal downward, so that the liquid metal flows back into the drum 11, preventing it from overflowing from the inner circle of the cover plate 202, preventing overflow from causing danger and affecting the formation of the pipe.

[0033] Further reference Figure 2 The drive assembly includes: a rotary motor 401, two support blocks 402, a connecting rod 403, two gears 404, two gears 405, two pulleys 406, and a belt 407. The rotary motor 401 is fixedly installed on one side of the top of the support plate 1. The two support blocks 402 are respectively fixedly installed on one side of the top of the support plate 1. One end of the connecting rod 403 is rotatably installed on one end of one of the support blocks 402, and the other end of the connecting rod 403 passes through the other support block 402. The connecting rod 403 and the other support block 402 are rotatably installed. The two gears 404 are respectively fitted on both ends of the circumference of the connecting rod 403. The two gears 405 are respectively fitted on both ends of the outer circumference of the roller 11. The two gears 404 are respectively meshed with the two gears 405. One pulley 406 is fixedly installed on the output shaft of the rotary motor 401, and the other pulley 406 is fixedly installed on the other end of the connecting rod 403. The belt 407 is meshed between the two pulleys 406.

[0034] When the rotating motor 401 is started, its output shaft drives the pulley 406 fixed on it to rotate. The pulley 406 drives another pulley 406 fixed on the connecting rod 403 to rotate synchronously through the belt 407. This causes the connecting rod 403 to rotate stably under the support of the two support blocks 402. The two gears 404 that rotate with the connecting rod 403 mesh with the two gears 405 that are sleeved on the outer wall of the drum 11. Through gear transmission, the drum 11 is driven to rotate around the inner wall of the bracket 10, thus realizing the function of driving the drum 11 to rotate.

[0035] Furthermore, refer to 2 and Figure 7The buffer assembly includes: several mounting blocks 501, several sleeves 502, several connecting rods 503, and several buffer springs 504. The mounting blocks 501 are arranged and fixedly installed on the outer circumference of the two supports 10. Each mounting block 501 has a central mounting opening at one end. The sleeves 502 are fixedly installed in the mounting openings. The two ends of the connecting rods 503 are inserted into the corresponding sleeves 502. The buffer springs 504 are respectively... The two ends of several connecting rods 503 are fixedly installed between the inner circumference of the corresponding sleeves 502; the top of one of the mounting slot plates 206 is fixedly installed on the other side of the gantry frame 204; sleeves 801 are fixedly installed on the opposite side of several mounting blocks 501; insert rods 802 are inserted into each sleeve 801; the opposite sides of several insert rods 802 are fixedly installed on the gantry frame 204; buffer springs 803 are fixedly installed between insert rods 802 and sleeves 801.

[0036] When the roller 11 rotates and vibrates, the vibration is transmitted to the two supports 10. The mounting blocks 501 on the outer circumference of the support 10 are subjected to force synchronously with the vibration. On the one hand, the mounting blocks 501 drive the sleeves 502 fixed in their mounting openings to move, causing the two ends of the connecting rods 503 inserted into the corresponding sleeves 502 to slide along the inner wall of the sleeves 502. This, in turn, compresses or stretches the buffer springs 504 between the sleeves 502 and the connecting rods 503. The elastic deformation of the buffer springs 504 absorbs part of the vibration. Vibration energy; on the other hand, the sleeve 801 on the side of the mounting block 501 that is far away from each other moves synchronously with the mounting block 501. Since one end of the insertion rod 802 is fixed to the gantry frame 204 and the other end is inserted into the sleeve 801, the sleeve 801 slides relative to the insertion rod 802 and squeezes or stretches the buffer spring 803 between the two. The vibration is further offset by the elastic deformation of the buffer spring 803. The double buffer structure works together to effectively reduce the vibration amplitude of the two supports 10 and ensure the stability of equipment operation.

[0037] Further reference Figure 3 and Figure 5 The first sliding component includes a slide rail 701 and a slider 702. The slide rail 701 is fixedly installed on the top inner wall of the corresponding mounting slot 205. The slider 702 is slidably installed on the slide rail 701. The bottom and top of the two sliders 702 are rotatably installed with the top and bottom of the two support rods 208, respectively. The second sliding component includes a slide rail 703 and a slider 704. The slide rail 703 is fixedly installed on the top inner wall of the mounting slot 206. The shape of the slide rail 703 fits the mounting slot 206. The slider 704 is slidably installed on the slide rail 703. The two sliders 704 are fixedly installed with the two support rods 209, respectively.

[0038] When the electric telescopic rod 2010 drives the cover plate 201 to move, the support rod 208 and support rod 209 connected to the cover plate 201 are simultaneously subjected to force: the top and bottom of the support rod 208 respectively drive the slider 702 of the sliding assembly to slide along the slide rail 701 fixed to the inner wall of the top of the mounting slot plate 205. Since the slider 702 and the support rod 208 are rotatably installed, they can be adapted to the angle fine adjustment during the movement process to ensure the stable sliding of the support rod 208; at the same time, the support rod 209 drives the slider 704 of the sliding assembly to slide along the slide rail 703 fixed to the inner wall of the top of the mounting slot plate 206. The slider 704 and the support rod 209 are fixedly connected to ensure that the movement trajectory is completely matched with the mounting slot plate 206. The two sets of sliding assemblies work together to provide precise guidance and stable support for the opening and closing of the cover plate 201.

[0039] Further reference Figure 6 Both cover plates 201 have threaded grooves on their inner circumferences, and both cover plates 202 have threaded tubes fixedly installed at their far ends. The outer circumference of the threaded tubes engages with the threaded grooves on the inner circumferences of the cover plates 201.

[0040] When it is necessary to replace the appropriate cover plate 202 to produce pipes of different diameters or thicknesses, the replacement operation can be achieved by rotating the cover plate 202. Rotating the cover plate 202 causes the threaded tube to unscrew along the thread groove, thereby releasing the fixed relationship between the cover plate 202 and the cover plate 1 201, and removing the old cover plate 202. Then, align the threaded tube of the new cover plate 202 with the thread groove of the cover plate 1 201, rotate the cover plate 202 in the opposite direction to screw the threaded tube into the thread groove and tighten it, thus completing the installation and fixing of the new cover plate 202. In this way, by replacing different cover plates 202, different specifications of pipes can be produced to meet the casting requirements of different amounts of liquid metal.

[0041] Working principle: First, fix the support plate 1 in the designated working area, ensuring that the two brackets 10 are firmly installed at both ends of the top of the support plate 1 to provide basic support. If different specifications of pipes need to be produced, the threaded pipe can be screwed out along the threaded groove of the cover plate 1 201 by rotating the cover plate 2 202. After replacing with a suitable cover plate 2 202, rotate it in the opposite direction and tighten it. Then, control the electric telescopic rod 2010 to extend, pushing the cover plate 1 201 towards the roller 11. At this time, the support rods 209 at the top and bottom of the cover plate 1 201 drive the slider 704 to first move along the mounting groove of the cover plate 2 201. The sliding motion transitions from an arc segment to a straight segment. The support rod 208 of the mounting plate 207 on one side of the cover plate 201 drives the slider 702 to rotate and then slide synchronously within the mounting groove 205. The two sets of sliding components work together to provide precise guidance until the cover plate 202 tightly adheres to the inner wall of the roller 11, completing one end sealing. The other end of the cover plate assembly is fixed with screws. Then, liquid metal is injected into the roller 11 through the cover plate 201 and cover plate 202. Subsequently, the rotating motor 401 is started, and its output shaft drives the connecting rod 403 via pulley 406 and belt 407. Rotating on support block 402, gear 404 on connecting rod 403 meshes with gear 405 on the outer wall of roller 11, driving roller 11 to rotate at high speed. During rotation, the vibration transmitted by bracket 10 drives sleeve 502 and connecting rod 503 to compress or stretch buffer spring 504 through mounting block 501. At the same time, sleeve 801 slides relative to insert rod 802 to compress or stretch buffer spring 803. The double buffer structure works together to reduce vibration. When roller 11 starts, the liquid metal inside flows to both ends under the action of centrifugal force. Limiting ring 301 and limiting ring 302 The inverted V-shaped cross section guides the liquid metal backflow in sequence to avoid overflow. After the centrifugal casting operation is completed, the drive assembly is turned off, and the electric telescopic rod 2010 is controlled to retract, which drives the cover plate 1 201, cover plate 2 202 and the limiting assembly to move in the opposite direction. The support rod 2 209 first slides along the straight section of the mounting groove plate 2 206 to the arc section. The support rod 1 208 is simultaneously reset along the mounting groove plate 1 205. Then the support rod 2 209 rotates around the support rod 1 208 in the arc section, so that the cover plate 1 201 is fully opened. The screws of the other end of the cover plate assembly can be removed and the cast pipe can be taken out.
