Description

Technical Field

[0001] The invention relates to the technical field of centrifugal casting equipment, in particular to a horizontal centrifugal casting machine which is convenient for demoulding. Background Art

[0002] Centrifugal casting is a technology and method of injecting liquid metal into a high-speed rotating mold, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. This technology uses a centrifugal casting machine for casting various tubular castings. There are two types of centrifugal casting machines: vertical centrifugal casting machines and horizontal centrifugal casting machines. This invention makes improvements to the horizontal centrifugal casting machine.

[0003] For example, publication number CN112517871A proposes a demoulding mechanism for a horizontal cantilever centrifugal casting machine, including a flip chuck and a traction mechanism connected to the flip chuck, wherein a plurality of clamping hydraulic cylinders are radially arranged on the flip chuck, the plurality of clamping hydraulic cylinders are arranged in a ring, and the extension directions of the telescopic ends of the plurality of clamping hydraulic cylinders are opposite to each other, and an ejection hydraulic cylinder is axially arranged on the flip chuck, and the extension direction of the telescopic end of the ejection hydraulic cylinder is opposite to the traction mechanism. The demoulding mechanism of the present invention utilizes the incomplete synchronization of the clamping hydraulic cylinders, and the clamping claws penetrate deep into the mold, which can be automatically centered, that is, the center of the moving clamping claws and the center of the mold can be not coaxial, so that they can be automatically centered, and the operation is convenient, and the device and the mold do not generate eccentric torque to cause damage to the operating device. It can reduce labor and improve safety. Especially for centrifugal castings with large diameter and heavy weight, the advantages of the demoulding mechanism of the present invention are particularly obvious.

[0004] When the device is demolding, the contact area between the clamping jaws and the casting is small, and then a large force is required to contact the casting to ensure the stability between the casting and the clamping jaws. However, the initially formed casting is soft in texture and is prone to irreversible deformation when subjected to a large force, thereby deforming the casting. Alternatively, the casting is cooled for a long time until it has sufficient structural strength and then the casting is pulled out of the mold by the clamping jaws. However, it takes a long time to wait for the casting to cool down, thereby reducing production efficiency.

[0005] In the prior art, the horizontal centrifugal casting machine needs to clean the mold before casting. Channel steel or angle steel is often used to knock the rotating mold to shake off the residue adhering to the inner wall of the mold, and then compressed air is used to blow out the fallen residue. This method is time-consuming and labor-intensive, and cannot ensure that the residue in the mold is cleaned.

[0006] In the prior art, a horizontal centrifugal casting machine needs to preheat the mold before casting. Most of the time, workers use a handheld flame spray gun to preheat the mold, and the workers bake the inside of the mold in sections. However, this preheating method requires workers to bake different parts of the mold back and forth. The preheating of the mold requires that the preheating temperature of the entire mold be consistent. This method is difficult to make the preheating temperature of the entire mold consistent.

[0007] In summary, a horizontal centrifugal casting machine that is easy to demould is proposed to solve the above problems. Summary of the invention

[0008] 1. Technical issues to be solved

[0009] In view of the deficiencies in the prior art, the present invention provides a horizontal centrifugal casting machine that is easy to demold, and has the advantages of a contact plate being firmly connected to the casting, a cooling water channel being provided in the contact plate to accelerate the cooling speed of the casting, the ability to quickly and efficiently clean the residues adhering to the inner wall of the mold, and the ability to make the preheating temperature of the entire mold consistent. The invention solves the problems of deformation of the casting due to the small contact area between the clamp and the casting, the need to wait for a long time for the casting to cool down so that it can reach sufficient structural strength before demolding, the inability to ensure that the residues in the mold are cleaned up, and the difficulty in making the preheating temperature of the entire mold consistent.

[0012] The beneficial effects of the present invention are:

[0013] 1) The horizontal centrifugal casting machine which is easy to demold, when the casting is initially formed, the expansion component is extended into the casting mold component, and the outer side of the expansion component is closely fitted with the inner wall of the casting through the expansion drive component, and then the water circulation component circulates water in the expansion component, which can accelerate the cooling of the casting. The casting shrinks when it cools down and can be separated from the inner wall of the casting mold component. It has the advantages of stable connection between the expansion component and the casting, accelerating the cooling of the casting, and thus shortening the time required for demolding a single piece.

[0014] 2) The horizontal centrifugal casting machine which is easy to demould allows the mold cleaning component to extend into the rotating mold component and move back and forth in the mold component, thereby separating the residues adhering to the inner wall of the mold component, and the fallen residues are sucked into the vacuum cleaner, which has the advantage of being able to quickly and efficiently clean the residues adhering to the mold component.

[0015] 3) The horizontal centrifugal casting machine which is easy to demould allows the bent tube to extend into the mold assembly, and the mold preheating assembly bakes the entire section of the rotating mold assembly at the same time, which has the advantage of making the preheating temperature of the entire mold assembly consistent.

[0016] Based on the above technical solution, the present invention can also be improved as follows.

[0017] Furthermore, the horizontal moving assembly includes a first threaded rod, a second pulley and a horizontal moving plate. The right side wall of the slide groove is rotatably connected to the first threaded rod extending to the left side of the base. The left end of the first threaded rod is fixedly connected to the second pulley. The second pulley and the outer side of the first pulley are sleeved with the same first synchronous belt. The outer side of the first threaded rod is threadedly connected to a horizontal moving plate that is slidably connected to the slide groove and located on the top of the base. A filling hopper is provided on the top of the horizontal moving plate.

[0018] The beneficial effect of adopting the above further scheme is that the first stepper motor is rotated through the control panel, which in turn drives the first pulley to rotate, and the first threaded rod is driven to rotate through the first synchronous belt and the second pulley. The force generated by the rotation of the thread drives the horizontal moving plate to slide to the right in the slide groove, thereby moving the filling hopper to the right.

[0019] Further, the rotation drive assembly includes a double-output shaft stepper motor and a gear, the inner concave block is provided with a double-output shaft stepper motor electrically connected to the control panel, and the output ends of the double-output shaft stepper motor are fixedly connected to the gear extending to the top of the inner concave block;

[0020] Furthermore, the casting assembly includes a gear ring, a cylindrical shell, a cylindrical casting, a casting end cover, a spring and a wedge head slider. Two gear rings meshing with the gears are provided above the inner recessed block. The interior of the gear ring is fixedly connected to the same cylindrical shell that is rotatably connected to the arc ring. The interior of the cylindrical shell is fixedly connected to the cylindrical casting. The interior of the cylindrical shell is provided with a casting end cover that is adapted to the cylindrical casting and fits tightly with the right side of the cylindrical casting. The casting end cover is separable from the cylindrical shell and the cylindrical casting. Springs symmetrically distributed up and down are provided inside the shell wall of the cylindrical shell. The opposite sides of the springs are fixedly connected to wedge head sliders slidably connected to the cylindrical shell. The left side of the wedge head slider is tightly fitted with the right side of the casting end cover, and the right side of the wedge head slider is adapted to the casting end cover. The casting end cover is adapted to the stepped liner sleeve.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that the filling hopper is extended into the casting assembly to an appropriate depth, and the double-output shaft stepper motor is rotated through the control panel. The output end of the double-output shaft stepper motor drives the gear to rotate synchronously. Since the gear is engaged with the gear ring, the cylindrical shell is driven to rotate on the opposite side of the inner concave block and the arc ring, and the molten metal is poured into the filling hopper and then enters the rotating casting assembly. The molten metal performs centrifugal motion in the casting end cover, so that the molten metal forms a tubular casting in the casting end cover. When the stepped liner sleeve is tightly fitted with the right side of the casting end cover, the stepped liner sleeve pushes the wedge head slider back into the cylindrical shell, and then causes the spring to undergo elastic deformation, thereby releasing the limit of the wedge head slider on the casting end cover, and the casting end cover can be separated from the cylindrical casting.

[0022] Furthermore, the longitudinal moving component includes a second threaded rod and a fourth pulley. The rear wall of the inner cavity of the rectangular shell is rotatably connected to a second threaded rod extending to its front side and threadedly connected to the mounting block. The front end of the second threaded rod is fixedly connected to a fourth pulley. The outer sides of the fourth pulley and the third pulley are provided with the same second synchronous belt.

[0023] The beneficial effect of adopting the above further scheme is that the second stepper motor is rotated through the control panel, which in turn drives the third pulley to rotate, thereby driving the fourth pulley and the second threaded rod to rotate through the second synchronous belt. Since the second threaded rod is threadedly connected to the carrying block, the force generated by the rotation of the thread can drive the carrying block to move longitudinally in the rectangular shell.

[0024] Furthermore, the mold cleaning assembly includes a columnar suction shell, a wire brush and an air inlet. The left end of the bending tube is fixedly connected to the columnar suction shell that is adapted to the cylindrical casting, the columnar suction shell is connected to the first hose, the outer side of the columnar suction shell is fixedly connected to the wire brushes distributed in a circular array and adapted to the cylindrical casting, and the outer side of the columnar suction shell is provided with an air inlet distributed in a circular array and connected to the interior.

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the leftmost section of the bent tube is made coaxial with the cylindrical mold, that is, the cylindrical suction shell is aligned with the cylindrical mold, the vacuum cleaner is started to operate through the control panel, and the electric push rod is operated at the same time. The output end of the electric push rod drives the rectangular shell to slide to the left in the movable groove, and then the cylindrical suction shell enters the rotating cylindrical mold. The wire brush separates the residue on the inner wall of the cylindrical mold from the inner wall, and the fallen residue is sucked into the vacuum cleaner through the air inlet and the first hose. The electric push rod is driven by the control panel to move the columnar suction shell entering the cylindrical mold back and forth left and right, so that the residue adhering to the inner wall of the cylindrical mold can be cleaned.

[0026] Furthermore, the mold preheating assembly includes a gas nozzle, a second hose, a combustible gas solenoid valve and a gas igniter. The top of the bent tube is provided with gas nozzles that are evenly distributed laterally. The inside of the bent tube is provided with a second hose that is connected to the gas nozzles. The other end of the second hose is provided with a combustible gas solenoid valve that is connected to the second hose. The combustible gas solenoid valve is connected to a gas storage tank, and the combustible gas solenoid valve and the gas igniter are both electrically connected to a control panel.

[0027] The beneficial effect of adopting the above-mentioned further scheme is that the leftmost section of the bent tube is made coaxial with the cylindrical casting mold, and the electric push rod is operated through the control panel. The output end of the electric push rod drives the rectangular shell to slide to the left in the movable groove, and then the bent tube drives the gas nozzle and the gas igniter to extend into the rotating cylindrical casting mold, so that the combustible gas solenoid valve is opened through the control panel, and the second hose is connected to the gas tank. The gas in the gas tank enters the cylindrical casting mold through the second hose and the gas nozzle, and at the same time, the gas igniter ignites the gas entering the cylindrical casting mold, so that the cylindrical casting mold can be baked. Since the cylindrical casting is baked while rotating, and the gas nozzles are extended into the cylindrical casting and are distributed equidistantly laterally, the entire section of the cylindrical casting can be baked at the same time, so that the preheating temperature of the entire cylindrical casting can be consistent.

[0028] Furthermore, the expansion assembly includes an internal threaded cone wheel, a supporting threaded rod, a contact plate and a cooling water channel. The internal part of the columnar stepped shell is rotatably connected to an internal threaded cone wheel that is symmetrically distributed on the left and right and extends to the outside thereof. The internal parts of the internal threaded cone wheel are all threadedly connected to supporting threaded rods extending above them. The top of the supporting threaded rod is fixedly connected to the same contact plate. The internal part of the contact plate is provided with a cooling water channel distributed in a serpentine shape.

[0029] Further, the expansion drive assembly includes a third stepper motor, a transmission shaft and a driving cone wheel. The third stepper motor electrically connected to the control panel is arranged inside the cylindrical shell. The output end of the third stepper motor is fixedly connected to the transmission shaft extending into the cylindrical stepped shell. The outer side of the transmission shaft is fixedly connected to the driving cone wheels distributed at equal distances in the transverse direction. The driving cone wheels are meshed with the corresponding internal threaded cone wheels.

[0030] Furthermore, the water circulation component includes a circulating water pump, an inlet elbow, a retractable spiral tube, an outlet elbow, a water suction pipe and a drain pipe. The support block is provided with a circulating water pump electrically connected to the control panel. The output end of the circulating water pump is provided with an inlet elbow extending through a cylindrical shell into a cylindrical stepped shell. The left end of the inlet elbow is provided with a retractable spiral tube connected to a cooling water channel. The other end of the cooling water channel is fixedly connected with a retractable spiral tube. The retractable spiral tube is connected to the outlet elbow. The outlet elbow extends through the cylindrical shell to the interior of the support block. The input end of the circulating water pump is provided with a water suction pipe extending into a water storage tank. The right end of the outlet elbow is provided with a drain pipe extending into the water storage tank.

[0031] The beneficial effect of adopting the above further scheme is that the columnar stepped shell is extended into the cylindrical casting mold and is coaxial with the cylindrical casting mold, the third stepper motor is rotated through the control panel, and then the driving cone wheel is driven to rotate through the transmission shaft. Since the driving cone wheel is engaged with the internal thread cone wheel, the internal thread cone wheel is driven to rotate. The force generated by the rotation of the thread causes the supporting threaded rod to move to the opposite side, so that the outer side of the contact plate is closely fitted with the inner wall of the initially formed casting, and then the circulating water pump is operated through the control panel to transport the water in the water tank through the suction pipe, the water inlet elbow and the retractable spiral pipe to the cooling water channel to form a water circulation, and the water flows back to the water tank through the water outlet elbow and the drain pipe, and then the initially formed casting is cooled and the casting is contracted, so that the outer side of the casting is separated from the inner wall of the cylindrical casting mold, the electric push rod is reset through the control panel, and then the casting is brought out of the cylindrical casting mold to complete the demolding of the casting.

[0050] The mold assembly 11 includes a gear ring 111, a cylindrical shell 112, a cylindrical mold 113, a mold end cover 114, a spring 115 and a wedge slider 116. Two gear rings 111 meshing with the gear 902 are provided above the inner concave block 8. The inner part of the gear ring 111 is fixedly connected to the same cylindrical shell 112 that is rotatably connected to the arc ring 10. The inner part of the cylindrical shell 112 is fixedly connected to the cylindrical mold 113. The inner part of the cylindrical shell 112 is provided with a casting that is adapted to and tightly fits with the right side of the cylindrical mold 113.

[0053] The second stepper motor 19 is rotated through the control panel 38, which in turn drives the third pulley 20 to rotate, thereby driving the fourth pulley 182 and the second threaded rod 181 to rotate through the second synchronous belt 21. Since the second threaded rod 181 is threadedly connected to the carrying block 17, the force generated by the rotation of the thread can drive the carrying block 17 to move longitudinally in the rectangular housing 16;

The third stepping motor 351 is rotated through the control panel 38, and then the driving cone wheel 353 is driven to rotate through the transmission shaft 352. Since the driving cone wheel 353 is engaged with the internal thread cone wheel 341, the internal thread cone wheel 341 is driven to rotate. The force generated by the rotation of the thread causes the supporting threaded rod 342 to move to the opposite side, so that the outer side of the contact plate 343 is closely fitted with the inner wall of the initially formed casting, and then the control panel 3 is used to control the contact plate 343. 8 operates the circulating water pump 371 to transport the water in the water tank 36 to the cooling water channel 344 through the water suction pipe 375, the water inlet elbow 372 and the telescopic spiral tube 373 to form a water circulation, and then flows back to the water tank 36 through the water outlet elbow 374 and the drain pipe 376, and then cools the initially formed casting to shrink the casting, so that the outer side of the casting is separated from the inner wall of the cylindrical mold 113, and the electric push rod 15 is reset through the control panel 38, and then the casting is taken out of the cylindrical mold 113 to complete the demolding of the casting.

The output end of the electric push rod 15 drives the rectangular shell 16 to slide leftward in the movable groove 13, and then the columnar suction shell 251 enters the rotating cylindrical mold 113, and the wire brush 252 separates the residue on the inner wall of the cylindrical mold 113 from the inner wall, and the fallen residue is sucked into the vacuum cleaner 23 through the air inlet 253 and the first hose 26. The electric push rod 15 drives the columnar suction shell 251 entering the cylindrical mold 113 to move back and forth through the control panel 38, so that the residue adhering to the inner wall of the cylindrical mold 113 can be cleaned.

[0060] Embodiment 3, on the basis of embodiment 1, the mold preheating assembly 27 comprises a gas nozzle 271, a second hose 272, a combustible gas solenoid valve 273 and a gas igniter 274, the top of the bent tube 22 is provided with gas nozzles 271 distributed at equal distances in the transverse direction, the inside of the bent tube 22 is provided with a second hose 272 connected to the gas nozzles 271, the other end of the second hose 272 is provided with a combustible gas solenoid valve 273 connected thereto, the combustible gas solenoid valve 273 is connected to the gas storage tank 24, and the combustible gas solenoid valve 273 and the gas igniter 274 are both electrically connected to the control panel 38;

[0061] The leftmost section of the bending tube 22 is made coaxial with the cylindrical mold 113, and the electric push rod 15 is operated through the control panel 38. The output end of the electric push rod 15 drives the rectangular housing 16 to slide to the left in the movable groove 13, and then the bending tube 22 drives the gas nozzle 271 and the gas igniter 274 to extend into the rotating cylindrical mold 113, so that the combustible gas solenoid valve 273 is opened through the control panel 38, so that the second hose 272 is connected to the gas storage tank 24, and the gas in the gas storage tank 24 is connected. The gas enters the cylindrical mold 113 through the second hose 272 and the gas nozzle 271, and the gas igniter 274 ignites the gas entering the cylindrical mold 113, so that the cylindrical mold 113 can be baked. Since the cylindrical mold 113 is baked while rotating, and the gas nozzles 271 are extended into the cylindrical mold 113 and are distributed at equal distances laterally, the entire section of the cylindrical mold 113 is baked at the same time, so that the preheating temperature of the entire cylindrical mold 113 can be consistent;

[0062] Working principle:

[0063] The first step to implement the innovation point:

[0064] Step 1: Before casting, the first stepper motor 4 is rotated through the control panel 38, which then drives the first pulley 5 to rotate, and the first threaded rod 301 is driven to rotate through the first synchronous belt 6 and the second pulley 302. The force generated by the rotation of the thread drives the horizontal movable plate 303 to slide rightward in the slide groove 2, so that the injection hopper 7 can be moved rightward, and the injection hopper 7 is extended into the mold assembly 11 to an appropriate depth. The double-output shaft stepper motor 901 is rotated through the control panel 38, and the output end of the double-output shaft stepper motor 901 drives the gear 902 to rotate synchronously. Since the gear 902 is meshed with the gear ring 111, the cylindrical shell 112 is driven to rotate on the opposite side of the inner concave block 8 and the arc ring 10, and the molten metal is poured into the injection hopper 7, and then enters the rotating mold assembly 11. The molten metal performs centrifugal motion in the mold end cover 114, so that the molten metal forms a tubular casting in the mold end cover 114;

[0065] Step 2: After the casting is initially formed in the cylindrical casting mold 113, the double-axis stepper motor 901 is stopped and the second stepper motor 19 is rotated through the control panel 38, and then the third pulley 20 is driven to rotate, thereby driving the fourth pulley 182 and the second threaded rod 181 to rotate through the second synchronous belt 21. Since the second threaded rod 181 is threadedly connected to the carrying block 17, the force generated by the rotation of the thread can drive the carrying block 17 to move longitudinally in the rectangular housing 16. In this process, when the second beam sensor transmitter 30 is aligned with the beam sensor receiver 12, the beam sensor receiver 12 transmits an electrical signal to the control panel 38, and the control panel 38 immediately causes the first beam sensor transmitter 30 to be aligned with the beam sensor receiver 12. The second stepper motor 19 stops rotating. At this time, the cylindrical shell 31, the stepped liner sleeve 32 and the cylindrical stepped shell 33 are all coaxial with the mold assembly 11. The electric push rod 15 is operated through the control panel 38. The output end of the electric push rod 15 drives the rectangular shell 16 to slide leftward in the movable groove 13, so that the cylindrical shell 31, the stepped liner sleeve 32 and the cylindrical stepped shell 33 are all entered into the mold assembly 11, and the stepped liner sleeve 32 is tightly fitted with the right side of the mold assembly 11. The stepped liner sleeve 32 pushes the wedge head slider 116 back into the cylindrical shell 112, and then the spring 115 is elastically deformed, thereby releasing the wedge head slider 116 from limiting the mold end cover 114;

[0066] Step 3: Make the columnar stepped shell 33 extend into the cylindrical mold 113 and be coaxial with the cylindrical mold 113, and rotate the third stepping motor 351 through the control panel 38, and then drive the driving cone wheel 353 to rotate through the transmission shaft 352. Since the driving cone wheel 353 is engaged with the internal thread cone wheel 341, the internal thread cone wheel 341 is driven to rotate. The force generated by the rotation of the thread causes the supporting thread rod 342 to move to the opposite side, so that the outer side of the contact plate 343 is closely attached to the inner wall of the initially formed casting, and then the control surface is used. The plate 38 operates the circulating water pump 371, and the water in the water tank 36 is transported to the cooling waterway 344 through the suction pipe 375, the water inlet elbow 372 and the retractable spiral tube 373 to form a water circulation, and then flows back into the water tank 36 through the outlet elbow 374 and the drain pipe 376, and then the initially formed casting is cooled, so that the casting shrinks, thereby separating the outer side of the casting from the inner wall of the cylindrical mold 113, and the electric push rod 15 is reset through the control panel 38, and then the casting is brought out of the cylindrical mold 113 to complete the demolding of the casting.

[0067] The second innovation point implementation steps:

[0068] Step 1: Before casting, the inside of the cylindrical mold 113 needs to be cleaned, and the cylindrical mold 113 is rotated through the control panel 38 to make the carrying block 17 move longitudinally in the rectangular shell 16. In this process, when the first beam sensor transmitter 28 is aligned with the beam sensor receiver 12, the beam sensor receiver 12 transmits an electrical signal to the control panel 38, and the control panel 38 immediately stops the second stepper motor 19 from rotating. At this time, the leftmost section of the bending tube 22 is coaxial with the cylindrical mold 113, that is, the columnar suction shell 251 is aligned with the cylindrical mold 113;

[0069] Step 2: The vacuum cleaner 23 starts to operate through the control panel 38, and the electric push rod 15 is operated at the same time. The output end of the electric push rod 15 drives the rectangular housing 16 to slide leftward in the movable groove 13, and then the columnar suction shell 251 enters the rotating cylindrical casting mold 113;

[0070] Step 3: The wire brush 252 separates the residue on the inner wall of the cylindrical mold 113 from the inner wall, and the fallen residue is sucked into the vacuum cleaner 23 through the air inlet 253 and the first hose 26. The electric push rod 15 drives the columnar suction shell 251 entering the cylindrical mold 113 to move back and forth through the control panel 38, so that the residue adhering to the inner wall of the cylindrical mold 113 can be cleaned.

[0071] The third innovation point implementation steps:

[0072] Step 1: Before casting, the cylindrical mold 113 needs to be preheated. The leftmost section of the bending tube 22 is made coaxial with the cylindrical mold 113 through the control panel 38. The electric push rod 15 is operated through the control panel 38. The output end of the electric push rod 15 drives the rectangular housing 16 to slide to the left in the movable groove 13, and then the bending tube 22 drives the gas nozzle 271 and the gas igniter 274 to extend into the rotating cylindrical mold 113.

[0073] Step 2: Open the combustible gas solenoid valve 273 through the control panel 38, connect the second hose 272 with the gas storage tank 24, and the gas in the gas storage tank 24 enters the cylindrical casting mold 113 through the second hose 272 and the gas nozzle 271. At the same time, the gas igniter 274 ignites the gas entering the cylindrical casting mold 113, so that the cylindrical casting mold 113 can be baked;

[0074] Step 3: Since the cylindrical mold 113 is baked while rotating, and the gas nozzles 271 are extended into the cylindrical mold 113 and are distributed at equal distances laterally, the entire section of the cylindrical mold 113 is baked simultaneously, so that the preheating temperature of the entire cylindrical mold 113 can be made consistent.
