Description

Technical Field

[0001] This invention relates to the field of mobile centrifugal metal casting machine technology, specifically a mobile centrifugal metal casting machine. Background Technology

[0002] Centrifugal casting involves pouring molten metal into a high-speed rotating mold, where centrifugal force causes the molten metal to fill and solidify. It is suitable for producing tubular, ring-shaped, and bimetallic castings, such as cast iron pipes, copper rollers, and rolling mill rolls. Centrifugal casting machines are classified into horizontal, vertical, and inclined types based on the mold's rotation axis. Horizontal machines are mostly used for long pipes, while vertical machines are mostly used for small disc and ring-shaped parts.

[0003] Existing metal centrifugal casting machines generally suffer from difficulties in movement, severely limiting their operating space and making them unsuitable for various work environments. This also causes great inconvenience for workers transporting molten metal. In addition, the equipment itself has a high center of gravity, making it prone to swaying or even tipping over during movement due to inertia. This can easily lead to spillage of molten metal and damage to the equipment itself. Furthermore, the lack of switchable support and walking structures and effective support, positioning, and protection structures makes it difficult to ensure the smooth and safe relocation of the equipment.

[0008] According to the above technical solution, the inner wall of the fixing frame is provided with a stabilizing device, which is used to fix and fit the casting cylinder and stabilize the equipment when the molten metal in the casting cylinder is being cast; the inside of the casting cylinder is provided with a discharge device, which is used to collect the oxide scale that falls into the bottom dead corner during centrifugal casting.

[0009] According to the above technical solution, the stabilizing device includes: a push plate, which is fixedly connected to the side wall of the sliding plate; The wedge-shaped block has a square groove on its inner wall, and the outer wall of the wedge-shaped block fits into the inner wall of the square groove. A positioning suction cup, wherein the positioning suction cup passes through the fixing frame and is slidably connected at the point of penetration; A positioning spring is fixedly connected to the side wall of the wedge block, and the end of the positioning spring away from the wedge block is fixedly connected to the inner wall of the square groove.

[0013] According to the above technical solution, the baffle is used to receive the oxide scale and seal the casting cylinder, and the positioning pin is used to position the collection box.

[0014] This invention provides a mobile centrifugal metal casting machine. It has the following advantages: 1. When the equipment needs to be moved, this invention allows the fixed frame to be moved from a side-to-ground support method to a swivel-wheel-to-ground support method by rotating the handle, in conjunction with rotating the axle, adjusting wheel, and supporting wheel. Pushing the handle allows the equipment to be moved, thus avoiding situations where the equipment is difficult to move and inconvenient for working in various locations. This solves problems such as the difficulty in moving the equipment, resulting in a fixed working environment and difficulties for workers in conveying molten metal. During equipment movement, the fixed rod, positioning ring, limiting ring, fixed plate, and sliding plate provide support and positioning, preventing the equipment from tipping over due to its high center of gravity and inertia, which could cause the molten metal inside to spill or damage the equipment. This solves the problem of the equipment easily tipping over due to shaking during movement.

[0015] 2. This invention is equipped with a stabilizing device. When the two casting cylinders are spliced ​​together and the casting cylinder is fixed, the push plate and wedge block work together to push the positioning suction cup to adhere to the ground, further fixing the equipment. This prevents the equipment from shaking and causing slight displacement during operation, which would lead to severe wear on the side wall of the fixing frame and reduce the service life of the equipment. This solves the problem that the equipment is prone to displacement due to shaking during operation. When stabilizing the equipment, the sealing ring, pull ring, and pull rod further seal and fix the casting cylinder, thereby preventing the casting cylinder from being misaligned due to the influence of molten metal during rotation, and preventing molten metal from leaking from the connection. This solves the problem that the large weight of the molten metal itself causes the casting cylinder to experience large inertia.

[0016] 3. This invention is equipped with a discharge device. After the equipment has finished working, it works with a collection box, spring rod, and baffle to collect the oxide scale generated during casting inside the mold cylinder. This prevents the oxide scale from falling into the dead corners of the inner wall of the mold cylinder and being difficult to discharge, which would result in more defects in the castings. This solves the problem of needing to stop for a long time when cleaning oxide scale. The connection between the collection box and the mold cylinder is fixed and limited by a positioning pin, a pressing block, a partition, a limiting spring, a stop block, a limiting rod, and a hinge rod. The centrifugal force generated when the mold cylinder rotates further enhances the stability of the connection between the collection box and the mold cylinder. At the same time, the baffle increases the sealing of the mold cylinder, preventing the molten metal from overflowing from the connection gaps of the mold cylinder. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a mobile metal centrifugal casting machine, including a fixed frame 1, a drive mechanism 2 fixed on the side wall of the fixed frame 1, the drive mechanism 2 including a drive motor, a drive shaft and a mounting plate, the drive motor fixedly connected to the side wall of the fixed frame 1, the drive shaft fixedly connected to the output end of the drive motor, the mounting plate fixedly connected to the end of the drive shaft away from the drive motor, and a casting cylinder 3 detachably mounted on the side of the mounting plate, the casting cylinder 3 being two parts broken in the middle, a pouring pipe 4 penetrating through the side wall of the casting cylinder 3 and fitting together at the penetration point, the drive mechanism 2 is started to make the casting cylinder 3 rotate, and then molten metal is poured into the pouring pipe 4, the rotation of the casting cylinder 3 makes the molten metal centrifugally cast inside; The mobile metal centrifugal casting machine also includes a fixed rod 5, a positioning ring 6, a limiting ring 7, a fixed plate 8, a sliding plate 9, a pusher 10, a rotating wheel axle 11, an adjusting wheel 12, a support wheel 13, a handle 14, and casters 15. The fixed rod 5 is fixedly connected to the side wall of the fixed frame 1. The positioning ring 6 is fixedly connected to the end of the fixed rod 5. The inner wall of the positioning ring 6 is in contact with the outer wall of the right half of the casting cylinder 3. The inner wall of the limiting ring 7 is in contact with the outer wall of the left half of the casting cylinder 3. The fixed plate 8 is fixedly connected to the side wall of the limiting ring 7. The pouring pipe 4 passes through the fixed plate 8 and is fixedly connected at the penetration point. The sliding plate 9 is fixedly connected to the outer wall of the limiting ring 7 and is slidably connected to the fixed plate 1. The metal casting mold is placed into the casting cylinder 3 on the outer wall of the frame 1. The sliding plate 9 is slidable, causing the sliding plate 9 to drive the fixing plate 8 to push the left casting cylinder 3 to fit against the right casting cylinder 3. The casting cylinder 3 is then fixed by the stabilizing device 16. At this time, the pouring pipe 4 is inserted into the casting cylinder 3 on the left side, and the fixing plate 8 continuously limits the pouring pipe 4. The push handle 10 is fixedly connected to the side wall of the sliding plate 9. The rotating wheel axle 11 is fixedly connected to the inner wall of the fixed frame 1. The adjusting wheel 12 is fixedly connected to both ends of the rotating wheel axle 11 and the side wall of the fixed frame 1. The support wheel 13 is fixedly connected to the outer wall of the adjusting wheel 12. The handle 14 is fixedly connected to the... The side wall of the adjusting wheel 12 and the universal wheel 15 are fixedly connected to the side wall of the fixed frame 1. When it is necessary to move the equipment, the operator needs to apply a supporting force on the right side of the support wheel 13 to prevent the support wheel 13 from moving. At the same time, the operator turns the handle 14, which drives the adjusting wheel 12 to rotate. The adjusting wheel 12, in conjunction with the rotating wheel axle 11, drives the fixed frame 1 to rotate, causing the fixed frame 1 to rotate 90°. The universal wheel 15 supports the fixed frame 1. When the universal wheel 15 supports the fixed frame 1, the operator pushes the pusher 10 to move the equipment. The fixing plate 8 is used to position the pouring pipe 4. The pouring pipe 4 is inserted into the casting cylinder 3 to pour the contents into it. The molten metal is poured into the casting cylinder 3. The limiting ring 7 is used to support and fix the casting cylinder 3. When the equipment is moved, the casting cylinder 3 changes from being placed horizontally to being placed vertically, and its center of gravity becomes higher. At this time, the casting cylinder 3 is on the inner wall of the positioning ring 6, and the positioning ring 6 is fixedly connected to the side wall of the fixed frame 1 through the fixing rod 5. The positioning ring 6 and the fixing rod 5, together with the limiting ring 7 and the sliding plate 9, support the casting cylinder 3 to prevent it from tipping over. The support wheel 13 is used as a fulcrum to support the fixed frame 1 when it is tilted. The handle 14 is used to rotate the adjusting wheel 12. The adjusting wheel 12 is used to adjust the placement of the fixed frame 1. When the equipment needs to be moved, by turning the handle 14, in conjunction with turning the wheel axle 11, adjusting wheel 12 and support wheel 13, the fixed frame 1 is changed from a support mode in which the side contacts the ground to a support mode in which the universal wheel 15 contacts the ground. Pushing the pusher 10 can move the equipment, thereby avoiding the situation where the equipment is difficult to move and inconvenient to work in various occasions. It solves the problems of the equipment being difficult to move, resulting in a fixed working environment and difficulties for workers to transport molten metal. When moving the equipment, the fixed rod 5, positioning ring 6, limiting ring 7, fixed plate 8 and sliding plate 9 are used to support and position the equipment, thereby preventing the equipment from tipping over due to its high center of gravity and inertia, which could cause the molten metal inside the equipment to spill out or damage the equipment. This solves the problem of the equipment easily tipping over due to shaking when moving.

[0021] In this embodiment, during operation: the metal casting mold is placed inside the casting cylinder 3. The sliding plate 9 is slidable, causing the sliding plate 9 to drive the fixing plate 8 to push the left casting cylinder 3 and the right casting cylinder 3 to fit together. Then, the casting cylinder 3 is fixed by the stabilizing device 16. At this time, the pouring pipe 4 is inserted into the casting cylinder 3 on the left side, and the fixing plate 8 continuously limits the pouring pipe 4. The drive mechanism 2 is started to rotate the casting cylinder 3, and molten metal is poured into the pouring pipe 4. The rotation of the casting cylinder 3 causes the molten metal to undergo centrifugal casting inside. When it is necessary to move the equipment, the operator needs to apply a supporting force on the right side of the support wheel 13 to prevent the support wheel 13 from moving while rotating. Handle 14 drives the adjusting wheel 12 to rotate. The adjusting wheel 12, together with the rotating wheel shaft 11, drives the fixed frame 1 to rotate, causing the fixed frame 1 to rotate 90°. The fixed frame 1 is supported by the universal wheel 15. When the universal wheel 15 supports the fixed frame 1, push the pusher 10 to move the equipment. When the equipment moves, the casting cylinder 3 changes from being placed horizontally to being placed vertically, and its center of gravity becomes higher. At this time, since the casting cylinder 3 is on the inner wall of the positioning ring 6, and the positioning ring 6 is fixedly connected to the side wall of the fixed frame 1 by the fixing rod 5, the positioning ring 6 and the fixing rod 5, together with the limiting ring 7 and the sliding plate 9, support the casting cylinder 3 to prevent the casting cylinder 3 from tipping over.

[0022] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the inner wall of the fixing frame 1 is provided with a stabilizing device 16, which is used to fix and cooperate with the casting cylinder 3 and stabilize the equipment when the molten metal in the casting cylinder 3 is cast. The stabilizing device 16 includes a push plate 161, a wedge block 162, a positioning suction cup 163, a positioning spring 164, a sealing ring 165, a pull ring 166, and a pull rod 167. The push plate 161 is fixedly connected to the side wall of the sliding plate 9. A square groove is formed on the inner wall of the fixing frame 1. The outer wall of the wedge block 162 fits against the inner wall of the square groove. The positioning suction cup 163 passes through the fixing frame 1 and is slidably connected at the penetration point. The wedge block 162 slides downward, pushing the positioning suction cup 163 to slide downward as well, adhering to the ground. The positioning spring 164 is fixedly connected to the side wall of the wedge block 162. The end of the positioning spring 164 away from the wedge block 162 is fixedly connected to the inner wall of the square groove. The wedge block 162 compresses the positioning spring 164. When the sliding plate 9 drives the push plate 161 to reset, the wedge block 162 is pushed forward by the restoring force of the positioning spring 164. The positioning suction cup 163 is pulled out to reset the casting cylinder 3. The sealing ring 165 passes through the casting cylinder 3 and is slidably connected at the point of penetration. The pull ring 166 is fixedly connected to the outer wall of the sealing ring 165. One end of the pull rod 167 is hinged to the outer wall of the positioning ring 6 and the limiting ring 7. The inner wall of the other end of the pull rod 167 is in contact with the outer wall of the pull ring 166. When the limiting ring 7 limits the casting cylinder 3, the sealing ring 165 is pushed so that the sealing ring 165 slides to the contact point on both sides of the casting cylinder 3. At this time, the pull rod 167 is rotated so that the pull rods 167 on both sides are in contact with the outer wall of the pull ring 166, and a pushing force is applied to the casting cylinder 3 so that the two sides of the casting cylinder 3 are in closer contact. The pull ring 166 and the pull rod 167 are made of fire-resistant rubber. The pull ring 166 and the pull rod 167 are used to position the sealing ring 165. The sealing ring 165 is used to seal and fix the casting cylinder 3. When the two casting cylinders 3 are spliced ​​together and the casting cylinder 3 is fixed, the positioning suction cup 163 is pushed to the ground by the push plate 161 and the wedge block 162 to further fix the equipment. This prevents the equipment from shaking and causing slight displacement during operation, which would lead to severe wear on the side wall of the fixing frame 1 and reduce the service life of the equipment. This solves the problem that the equipment is prone to displacement due to shaking during operation. When stabilizing the equipment, the sealing ring 165, pull ring 166 and pull rod 167 are used to further seal and fix the casting cylinder 3, thereby preventing the casting cylinder 3 from being misaligned due to the influence of the molten metal when rotating, and preventing the molten metal from leaking from the connection. This solves the problem that the casting cylinder 3 is subject to a large inertia due to the large weight of the molten metal itself.

[0023] The casting cylinder 3 is equipped with a discharge device 17. The discharge device 17 is used to collect the oxide scale that falls into the bottom dead corner during centrifugal casting. The discharge device 17 includes a collection box 171, a spring rod 172, a baffle 173, a positioning pin 174, a pressing block 175, a partition 176, a limiting spring 177, a stop block 178, a limiting rod 179, and a hinge rod 1710. The collection box 171 penetrates the casting cylinder 3 and is slidably connected at the penetration point. A spring rod 172 is fixedly connected to the bottom surface of the inner wall of the collection box 171. A baffle 173 is fixedly connected to the end of the spring rod 172 away from the collection box 171. When casting is complete, some oxide scale will fall from the inside of the casting cylinder 3. At this time, turning the handle 14 will raise the equipment, and the oxide scale will slide along the inner wall of the casting cylinder 3 to the baffle 173. When the baffle 173 is pulled out, the oxide scale on the baffle 173 slides on the bottom surface of the inner wall of the casting cylinder 3. The casting cylinder 3 scrapes off the oxide scale that may have adhered to the baffle 173 due to high-temperature cooling and pushes it into the collection box 171. A positioning pin 174 penetrates the collection box 171, and... The passage is slidably connected, the extrusion block 175 is fixedly connected to the upper surface of the positioning pin 174, the partition 176 is fixedly connected to the bottom surface of the inner wall of the collection box 171, the limiting spring 177 is fixedly connected to the side wall of the partition 176, the stop block 178 is fixedly connected to the end of the limiting spring 177 away from the partition 176, the limiting rod 179 passes through the collection box 171 and is slidably connected at the passage, the hinge rod 1710 is hinged to the end of the limiting rod 179, the end of the hinge rod 1710 away from the limiting rod 179 is hinged to the upper surface of the extrusion block 175, the baffle 173 is used to receive the oxide scale and seal the casting cylinder 3, and the positioning pin 174 is used to position the collection box 171; After the equipment finishes working, it works with the collection box 171, spring rod 172 and baffle 173 to collect the oxide scale generated during casting inside the casting cylinder 3. This prevents the oxide scale from falling into the dead corners of the inner wall of the casting cylinder 3 and being difficult to discharge, which would result in more defects in the casting produced. It also solves the problem of needing to stop the machine for a long time when cleaning the oxide scale. The connection between the collection box 171 and the casting cylinder 3 is fixed and limited by a positioning pin 174, a pressing block 175, a partition 176, a limiting spring 177, a stop block 178, a limiting rod 179, and a hinge rod 1710. The centrifugal force generated when the casting cylinder 3 rotates further enhances the stability of the connection between the collection box 171 and the casting cylinder 3. At the same time, the baffle 173 increases the sealing of the casting cylinder 3, preventing the molten metal from overflowing from the connection gap of the casting cylinder 3.

[0024] In this embodiment, during casting, the handle 14 is rotated to make the equipment horizontal, and the sliding plate 9 is pushed towards the casting cylinder 3. The sliding plate 9 drives the push plate 161 to move. When the push plate 161 moves to the wedge block 162, the side of the push plate 161 slides against the inclined surface of the wedge block 162. The push plate 161 pushes the wedge block 162 downward, and the downward sliding of the wedge block 162 pushes the positioning suction cup 163 to slide downward as well, adhering it to the ground. At the same time, the wedge block 162... 62 compresses the positioning spring 164. When the sliding plate 9 drives the push plate 161 to reset, the wedge block 162 is reset by the restoring force of the positioning spring 164, pulling out the positioning suction cup 163. When the limiting ring 7 limits the casting cylinder 3, it pushes the sealing ring 165, causing the sealing ring 165 to slide to the contact point on both sides of the casting cylinder 3. At this time, the pull rod 167 is rotated so that the pull rods 167 on both sides are in contact with the outer wall of the pull ring 166, applying a pushing force to the casting cylinder 3, making the two sides of the casting cylinder 3 fit more tightly.

[0025] When casting is complete, some oxide scale will fall off from the inside of the casting cylinder 3. At this time, turn the handle 14 to raise the equipment. The oxide scale slides along the inner wall of the casting cylinder 3 to the baffle 173. When the baffle 173 is pulled out, the oxide scale on the baffle 173 slides on the bottom surface of the inner wall of the casting cylinder 3. The casting cylinder 3 scrapes off the oxide scale that may have adhered to the baffle 173 due to high temperature cooling and pushes it into the collection box 171. When it is necessary to pull out the collection box 171, push the limiting rod 179 towards the casting cylinder 3. The limiting rod 179 drives the hinge point between the limiting rod 179 and the hinge rod 1710 to move away from the extrusion block 175. The length of the hinge rod 1710 remains unchanged. When the limiting rod 179 slides towards the casting cylinder 3, it drives the hinge rod 1710 to rotate, pulling the extrusion block 175 upward. The upward movement causes the positioning pin 174 to slide upward. When the extrusion block 175 moves upward, it pushes the stop block 178 to slide towards the limiting spring 177, while simultaneously compressing the limiting spring 177. When the limiting rod 179 is released, the restoring force of the limiting spring 177 pushes the stop block 178 to reset. The stop block 178 pushes the extrusion block 175 to move downward. The extrusion block 175 pushes the positioning pin 174 to slide downward, so that the positioning pin 174 limits the collection box 171. When the casting cylinder 3 rotates, the limiting rod 179 is also subjected to centrifugal force and slides away from the casting cylinder 3. At this time, the hinge point between the limiting rod 179 and the hinge rod 1710 moves towards the extrusion block 175, further applying a downward pushing force to the extrusion block 175, so that the collection box 171 will not be thrown out by centrifugal force.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
