Description
Technical Field
[0001] The invention relates to the technical field of casting, in particular to a metal flange casting device and a casting method which are convenient for temperature control and heat dissipation. Background Art
[0002] Flange refers to a connector at the end of a pipe or on a device, used to connect two pipes or devices to achieve sealing and connection. A flange is a metal disc with holes, generally produced by casting.
[0003] When metal flanges are cast using vertical centrifugal casting, the flowing molten iron adheres to the inner wall of the mold under the action of centrifugal force. However, under the influence of the molten iron's own gravity, a slope is formed on the inner hole of the flange, resulting in substandard casting accuracy. In addition, the thickness of the casting is inconsistent at different locations, and more heat is accumulated at locations with greater thickness. If the same cooling efficiency is used to dissipate heat, the cooling time at different locations of the forging will be inconsistent, making it impossible for the forging to dissipate heat evenly. Summary of the invention
[0004] The object of the present invention is to provide a metal flange casting device and a casting method which are convenient for temperature control and heat dissipation, so as to solve the problems raised in the prior art.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution of metal flange casting equipment and casting method which are convenient for temperature control and heat dissipation, the casting equipment includes a frame, a shell, a power motor and a casting mechanism, the shell is tightly connected to the frame, a feed port is provided on the shell, the power motor is tightly connected to the frame, the output end of the power motor is transmission-connected to the casting mechanism, a working chamber is provided in the shell, the casting mechanism is located in the working chamber, and the casting mechanism is used to adjust the state of molten iron.
[0006] The frame is used to provide stable support for each mechanism. The power motor is the main power source of the casting equipment. The power motor is used to drive the casting mechanism to move. The casting mechanism is processed by centrifugal casting. The molten iron enters the casting mechanism from the feed port on the shell for processing. However, because the present invention is cast by vertical centrifugal casting, the flowing molten iron in the casting mechanism will tend to flow downward under the influence of its own gravity, resulting in the formation of an inclined surface on the inner wall of the final formed flange, thereby affecting the casting accuracy.
[0007] Furthermore, the casting mechanism includes a rotating body, an adjusting assembly and a mold assembly. The rotating body is provided with a rotating shaft. The output end of the power motor is provided with a transmission belt. The transmission belt is transmission-connected to the rotating shaft. The adjusting assembly is tightly connected to the rotating body. The adjusting assembly is used to drive the mold assembly to swing back and forth. The mold assembly is tightly connected to the adjusting assembly.
[0008] The transmission belt at the output end of the power motor transmits power to the rotating body through the rotating shaft, thereby driving the rotating body to rotate, and then driving the mold assembly fixed on the rotating body to rotate around the rotating body. The molten iron in the mold assembly is formed into the shape to be processed under the action of centrifugal force. In order to offset the influence of the self-generated gravity of the molten iron, the mold assembly is driven to swing back and forth within a certain range through the adjustment component, so that the molten iron is subjected to an additional upward centrifugal force, thereby offsetting the influence of the molten iron's own gravity, thereby improving the casting quality.
[0009] Furthermore, the adjustment component includes a guide rail, a reciprocating electric cylinder, a rack, an adjustment shaft and a transmission wheel. The guide rail is tightly connected to the rotating body, the reciprocating electric cylinder is tightly connected to the rotating body, the output end of the reciprocating electric cylinder is transmission-connected to the rack, the rack is slidingly connected to the guide rail, the adjustment shaft is rotationally connected to the rotating body, the adjustment shaft is tightly connected to the mold assembly, the transmission wheel is tightly connected to the adjustment shaft, and the transmission wheel is provided with a tooth surface, which meshes with the rack.
[0010] During centrifugal casting, the mold assembly not only rotates on its own driven by the rotating body, but also swings back and forth driven by the adjusting assembly. The reciprocating electric cylinder drives the rack to move left and right on the guide rail, thereby driving the transmission wheel meshing with the rack to rotate back and forth, thereby driving the adjusting shaft to rotate back and forth on the rotating body, and then driving the mold assembly fixedly connected to the adjusting shaft, so as to realize the reciprocating swing of the mold assembly.
[0011] Furthermore, the mold assembly includes an upper mold cover and a lower mold body, the upper mold cover is clamped with the lower mold body, the lower mold body is tightly connected to the adjustment shaft, and a mold cavity is arranged in the lower mold body.
[0012] The upper mold cover and the lower mold body that are locked together can facilitate the disassembly and assembly of the mold assembly. The molten iron flows into the mold cavity in the lower mold body from the opening on the upper mold cover. The cross-section of the mold cavity is the same as that of the flange. The molten iron will fit into the mold cavity under the action of centrifugal force, thereby completing centrifugal casting.
[0013] Furthermore, arc-shaped sliders are symmetrically arranged at the bottom end of the lower mold body, and a guide groove is provided on the rotating body. The guide groove is arc-shaped, and the arc-shaped slider is slidably connected to the guide groove.
[0014] In order to ensure the stability of the lower mold body when it is driven by the adjustment component to make reciprocating swings, the movement of the lower mold body is guided by the cooperation of the arc-shaped guide groove and the arc-shaped slider.
[0015] Furthermore, a heat dissipation mechanism is provided in the mold assembly, and the heat dissipation mechanism is used to cool and dissipate heat from the casting.
[0016] After the casting is completed, the casting is cooled by the heat dissipation mechanism to facilitate the removal of the workpiece from the mold assembly.
[0017] Furthermore, the heat dissipation mechanism includes a heat dissipation coil, a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are respectively connected to the heat dissipation coil, a number of heat dissipation coils are arranged in the mold assembly, and a plurality of heat dissipation coils are connected to a guide assembly, which is used to adjust the heat dissipation efficiency.
[0018] The water inlet pipe and the water outlet pipe are connected to an external cooling water source, and the cooling water flows into the heat dissipation coil by pumping. The heat dissipation coil is evenly arranged on the outside of the mold cavity, and can evenly dissipate heat for the casting in the mold cavity. However, the thickness of the casting is inconsistent at different locations, and more heat is accumulated at locations with greater thickness. If the same cooling efficiency is used for heat dissipation, the cooling time at different locations of the forging will be inconsistent, making it impossible for the forging to dissipate heat evenly. The guide component automatically adjusts the heat dissipation efficiency of the corresponding location according to the amount of heat, thereby improving the cooling effect.
[0019] Furthermore, the deflector assembly includes a deflector cover, a movable block, a support spring, an electromagnet, a repelling magnet, a piston rod, a return spring and a top block. The deflector cover is connected to the heat dissipation coil, and an arc groove is provided on the deflector cover. The movable block is provided with a rotating pin and a swing pin. The rotating pin is rotatably connected to the deflector cover, and the swing pin is slidably connected to the arc groove. The support spring is arranged in the arc groove, and the support spring is tightly connected to the swing pin. A movable groove is provided in the movable block, and the electromagnet is tightly connected to the inner wall of the movable groove. The repelling magnet is tightly connected to the piston rod, and the facing ends of the repelling magnet and the electromagnet are the same magnetic poles. The piston rod is slidably connected to the movable groove, and a return spring is sleeved on the piston rod. A top block is provided on the end of the piston rod away from the repelling magnet. An elastic layer is provided on the outer wall of the movable block, and the top block abuts against the elastic layer. A thermistor is provided at the water-facing end of the movable block, and the thermistor is electrically connected to the electromagnet.
[0020] When the cooling water passes through the heat dissipation coil, it will absorb the heat of the forging, and the heat at different positions of the forging is inconsistent. The water flow temperature in the heat dissipation coil in the area with more heat will be higher. The thermistor and the electromagnet are connected to an external power supply to form a complete circuit. The higher the temperature the thermistor is subjected to, the smaller the resistance value; when the cooling water temperature is normal, the repulsive force of the electromagnet on the repulsive magnet cannot overcome the elastic force of the reset spring, and the swing pin on the movable block remains horizontal under the support of the support spring in the arc groove. The streamlined movable block guides the cooling water to keep the cooling water in a laminar state; and the cooling water mainly dissipates heat through heat conduction. When laminar flow flows, since the fluids between the layers do not mix with each other, the heat exchange method is mainly conduction. Turbulent flow is the violent mixing of the fluids in the layers, which greatly enhances the heat exchange. Therefore, the heat dissipation coefficient is higher in turbulent flow than in laminar flow, that is, the heat transfer effect of turbulent flow is good; when the temperature of the cooling water is too high, the thermistor at the water-facing end of the movable block can first contact the water flow passing through the heat dissipation coil, and the higher the temperature of the water flow, the smaller the resistance value of the thermistor, and the electricity transmitted to the electromagnet The greater the flow, the greater the repulsive force of the electromagnet on the repulsive magnet, overcoming the elastic force of the return spring, thereby driving the piston rod to move upward along the movable groove, so that the top block lifts the elastic layer, and the curved surface height of one side of the movable block is higher than that of the other side, so that the cooling water flow rate at the curved surface on the raised side will be higher than the cooling water flow rate on the other side, and the cooling water pressure on the side with fast flow rate is lower than the pressure on the side with slow flow rate. The pressure difference of the cooling water on both sides of the movable block will give the movable block a thrust, so that the swing pin on the movable block rotates along the arc groove, and the two deflected movable blocks will convert the laminar cooling water into a turbulent state. The higher the temperature, the greater the repulsive force of the electromagnet on the repulsive magnet, the greater the bulge of the top block lifting the elastic layer, the greater the pressure difference of the cooling water on both sides of the movable block, the greater the thrust received by the movable block, the greater the offset angle, the greater the turbulence caused, and the higher the heat dissipation efficiency, that is, the heat dissipation efficiency is automatically adjusted according to the temperature of the cooling water. The higher the temperature, the higher the heat dissipation efficiency, thereby ensuring that the cooling time of various parts of the forging is consistent, thereby improving the uniformity of cooling of the forging.
[0021] Further, the method comprises the following steps: S1: Add molten iron into the mold assembly from the feed port; S2: Start the power motor to drive the mold assembly to rotate, so that the molten iron is filled into the mold cavity under the action of centrifugal force; S3: adjusting the state of the molten iron in the mold assembly through the adjusting assembly, and cooling the formed parts through the heat dissipation mechanism; S4: Finally, open the upper mold cover and take out the parts in the lower mold body.
[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The reciprocating electric cylinder drives the rack to move left and right on the guide rail, thereby driving the transmission wheel meshing with the rack to rotate back and forth, thereby driving the adjusting shaft to rotate back and forth on the rotating body, and then driving the mold assembly fixedly connected to the adjusting shaft, so as to realize the reciprocating swing of the mold assembly, so that the molten iron is subjected to an additional upward centrifugal force, thereby offsetting the influence of the molten iron's own gravity, thereby improving the casting quality.
[0023] 2. By setting a rotatable movable block in the deflector, when the cooling water temperature is too high, the movable block is adjusted to convert the original laminar flow of cooling water into turbulent flow, thereby improving the heat dissipation efficiency. After the temperature returns to normal, the elastic force of the supporting spring resets the movable block and guides the cooling water in the turbulent state to the laminar state again, thereby achieving the effect of adjusting the heat dissipation efficiency in real time according to the temperature, thereby ensuring the cooling effect of the forging.
[0024] 3. By arranging the electromagnets and repelling magnets in opposite directions, the influence of the change of cooling water temperature on the resistance of the thermistor is utilized. When the temperature is higher, the repulsive force of the electromagnet on the repelling magnet is greater, and the height of the elastic layer lifted by the top block is higher, so that the height of the curved surface on one side of the movable block is higher than that on the other side. In this way, the cooling water flow rate at the curved surface on the raised side will be higher than that on the other side, and the cooling water pressure on the side with fast flow rate will be lower than that on the side with slow flow rate. The pressure difference of the cooling water on both sides of the movable block will give the movable block a thrust, so that the swing pin on the movable block rotates along the arc groove. The two deflected movable blocks will transform the laminar state of cooling water into a turbulent state, thereby improving the heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The molten iron enters the casting mechanism 4 from the feed port 21 on the shell 2 for processing. However, because the present invention is cast by vertical centrifugal casting, the flowing molten iron in the casting mechanism 4 will tend to flow downward under the influence of its own gravity, resulting in the formation of an inclined surface on the inner wall of the final formed flange, thereby affecting the casting accuracy.
[0030] The casting mechanism 4 includes a rotating body 41, an adjusting component 42 and a mold component 43. The rotating body 41 is provided with a rotating shaft 411.

The adjusting component 42 is tightly connected to the rotating body 41. The adjusting component 42 is used to drive the mold component 43 to swing back and forth. The mold component 43 is tightly connected to the adjusting component 42.
[0031] The transmission belt 31 at the output end of the power motor 3 transmits power to the rotating body 41 through the rotating shaft 411, thereby driving the rotating body 41 to rotate, and then driving the mold assembly 43 fixed on the rotating body 41 to rotate around the rotating body 41. The molten iron in the mold assembly 43 is formed into a shape to be processed under the action of centrifugal force. In order to offset the influence of the self-generated gravity of the molten iron, the mold assembly 43 is driven to swing back and forth within a certain range through the adjustment assembly 42, so that the molten iron is subjected to an additional upward centrifugal force, thereby offsetting the influence of the molten iron's own gravity, thereby improving the casting quality.
[0032] The adjusting assembly 42 includes a guide rail 421, a reciprocating electric cylinder 422, a rack 423, an adjusting shaft 424 and a transmission wheel 425.

[0033] During centrifugal casting, the mold assembly 43 not only rotates on its own under the drive of the rotating body 41, but also swings back and forth under the drive of the adjusting assembly 42. The reciprocating electric cylinder 422 drives the rack 423 to move left and right on the guide rail 421, thereby driving the transmission wheel 425 meshing with the rack 423 to rotate back and forth, thereby driving the adjusting shaft 424 to rotate back and forth on the rotating body 41, and then driving the mold assembly 43 fixedly connected to the adjusting shaft 424, so as to realize the reciprocating swing of the mold assembly 43.

[0035] The upper mold cover 431 and the lower mold body 432 that are interlocked with each other can facilitate the disassembly and assembly of the mold assembly 43. The molten iron flows into the mold cavity 4321 in the lower mold body 432 from the opening on the upper mold cover 431. The cross-section of the mold cavity 4321 is the same as the cross-section of the flange. The molten iron will adhere to the mold cavity 4321 under the action of centrifugal force, thereby completing centrifugal casting.

[0037] In order to ensure the stability of the lower mold body 432 when it is driven by the adjustment component 42 to make a reciprocating swing, the arc-shaped guide groove 412 cooperates with the arc-shaped slider 4322 to guide the movement of the lower mold body 432.
[0038] A heat dissipation mechanism 5 is provided in the mold assembly 43, and the heat dissipation mechanism 5 is used to cool and dissipate heat of the casting.
[0039] After the casting is completed, the casting is cooled by the heat dissipation mechanism 5 so as to facilitate the removal of the workpiece from the mold assembly 43 .
[0040] The heat dissipation mechanism 5 includes a heat dissipation coil 51, a water inlet pipe 52 and a water outlet pipe 53. The water inlet pipe 52 and the water outlet pipe 53 are respectively connected to the heat dissipation coil 51. Several heat dissipation coils 51 are arranged in the mold assembly 43. Several heat dissipation coils 51 are connected to a guide assembly 54, which is used to adjust the heat dissipation efficiency.
[0041] The water inlet pipe 52 and the water outlet pipe 53 are connected to an external cooling water source, and the cooling water flows into the heat dissipation coil 51 by pumping. The heat dissipation coil 51 is evenly arranged on the outside of the mold cavity 4321, and can evenly dissipate heat for the casting in the mold cavity 4321. However, the thickness of the casting is inconsistent at different locations, and more heat is accumulated at locations with greater thickness. If the same cooling efficiency is used for heat dissipation, the cooling time at different locations of the forging will be inconsistent, making it impossible for the forging to dissipate heat evenly. The guide component 54 automatically adjusts the heat dissipation efficiency of the corresponding location according to the amount of heat, thereby improving the cooling effect.
[0042] The guide assembly 54 includes a guide cover 541, a movable block 542, a support spring 543, an electromagnet 544, a repelling magnet 545, a piston rod 546, a reset spring 547 and a top block 548. The guide cover 541 is connected to the heat dissipation coil 51. The guide cover 541 is provided with an arc groove 5411. The movable block 542 is provided with a rotating pin 5421 and a swing pin 5422. The rotating pin 5421 is rotatably connected to the guide cover 541. The swing pin 5422 is slidably connected to the arc groove 5411. The support spring 543 is arranged in the arc groove 5411. The support spring 543 is fastened to the swing pin 5422. The movable block 542 is provided with a There is a movable groove 5423, the electromagnet 544 is tightly connected to the inner wall of the movable groove 5423, the repelling magnet 545 is tightly connected to the piston rod 546, the facing ends of the repelling magnet 545 and the electromagnet 544 are the same magnetic poles, the piston rod 546 is slidingly connected to the movable groove 5423, a return spring 547 is sleeved on the piston rod 546, a top block 548 is provided on the end of the piston rod 546 away from the repelling magnet 545, an elastic layer 5424 is provided on the outer wall surface of the movable block 542, the top block 548 abuts against the elastic layer 5424, a thermistor 549 is provided on the water-facing end of the movable block 542, and the thermistor 549 is electrically connected to the electromagnet 544.
[0043] When the cooling water passes through the heat dissipation coil 51, it absorbs the heat of the forging. However, the heat at different positions of the forging is inconsistent. The water temperature in the heat dissipation coil 51 in the area with more heat will be higher. The thermistor 549 and the electromagnet 544 are connected to an external power supply to form a complete circuit. The higher the temperature of the thermistor 549, the smaller the resistance value. When the cooling water temperature is normal, the repulsive force of the electromagnet 544 on the repulsive magnet 545 cannot overcome the elastic force of the reset spring 547. The swing pin 5422 on the movable block 542 is supported by the support spring 543 in the arc groove 5411 to maintain a horizontal state. The streamlined movable block 542 is The movable block 542 guides the cooling water so that the cooling water maintains a laminar flow state. When the cooling water dissipates heat, it mainly uses heat conduction. When the laminar flow flows, since the fluids between the layers do not mix with each other, the heat exchange method is mainly conduction. Turbulent flow is a violent mixing of the fluids in the layers, which greatly enhances the heat exchange. Therefore, the heat dissipation coefficient is higher in turbulent flow than in laminar flow, that is, the heat transfer effect of turbulent flow is good. When the temperature of the cooling water is too high, the thermistor 549 at the water-facing end of the movable block 542 can first contact the water flow passing through the heat dissipation coil 51, and the higher the temperature of the water flow, the smaller the resistance of the thermistor 549 is, which is transmitted to the electromagnet 54. 4, the greater the repulsive force of the electromagnet 544 on the repulsive magnet 545, overcoming the elastic force of the return spring 547, thereby driving the piston rod 546 to move upward along the movable groove 5423, so that the top block 548 lifts up the elastic layer 5424, so that the height of the curved surface on one side of the movable block 542 is higher than that on the other side, so that the cooling water flow rate at the curved surface on the raised side will be higher than the cooling water flow rate on the other side, and the cooling water pressure on the side with a faster flow rate is lower than the pressure on the side with a slower flow rate. The pressure difference of the cooling water on both sides of the movable block will give the movable block a thrust, causing the swing pin 5422 on the movable block to rotate along the arc groove The two deflected movable blocks 542 will convert the laminar flow of cooling water into a turbulent flow state, and the higher the temperature, the greater the repulsive force of the electromagnet 544 on the repulsive magnet 545, the greater the protrusion of the top block 548 that lifts up the elastic layer 5424, the greater the pressure difference of the cooling water on both sides of the movable block, the greater the thrust exerted on the movable block, the greater the offset angle, the greater the turbulence caused, and the higher the heat dissipation efficiency, that is, the heat dissipation efficiency is automatically adjusted according to the temperature of the cooling water. The higher the temperature, the higher the heat dissipation efficiency, thereby ensuring that the cooling time of each part of the forging remains consistent and improving the uniformity of cooling of the forging.
[0044] The method comprises the following steps: S1: Add molten iron into the mold assembly 43 from the feed port 21; S2: starting the power motor 3 to drive the mold assembly 43 to rotate, so that the molten iron is filled into the mold cavity 4321 under the action of centrifugal force; S3: adjusting the state of the molten iron in the mold assembly 43 through the adjusting assembly 42, and cooling the formed parts through the heat dissipation mechanism 5; S4: Finally, open the upper mold cover 431 and take out the parts in the lower mold body 432.
[0045] The working principle of the present invention is as follows: during centrifugal casting, the mold assembly 43 not only rotates on its own under the drive of the rotating body 41, but also swings back and forth under the drive of the adjusting assembly 42. The rack 423 is driven to move left and right on the guide rail 421 by the reciprocating electric cylinder 422, thereby driving the transmission wheel 425 meshing with the rack 423 to rotate back and forth, thereby driving the adjusting shaft 424 to rotate back and forth on the rotating body 41, thereby driving the mold assembly 43 fixedly connected to the adjusting shaft 424, thereby realizing the reciprocating swing of the mold assembly 43, so that the molten iron is subjected to an additional upward centrifugal force, thereby offsetting the influence of the molten iron's own gravity, thereby improving the casting quality.
[0046] When the cooling water passes through the heat dissipation coil 51, it absorbs the heat of the forging. However, the heat at different positions of the forging is inconsistent. The water temperature in the heat dissipation coil 51 in the area with more heat will be higher. When the temperature of the cooling water is too high, the thermistor 549 at the water-facing end of the movable block 542 can first contact the water passing through the heat dissipation coil 51. The higher the temperature of the water flow, the smaller the resistance of the thermistor 549, the greater the current transmitted to the electromagnet 544, and the greater the repulsive force of the electromagnet 544 on the repulsive magnet 545, thereby overcoming the elastic force of the return spring 547, thereby driving the piston rod 546 along the The movable groove 5423 moves upward, so that the top block 548 lifts up the elastic layer 5424, so that the height of the curved surface on one side of the movable block 542 is higher than that on the other side. In this way, the cooling water flow rate at the curved surface on the raised side will be higher than the cooling water flow rate on the other side, and the cooling water pressure on the side with fast flow rate is lower than the pressure on the side with slow flow rate. The pressure difference of the cooling water on both sides of the movable block will give the movable block a thrust, so that the swing pin 5422 on the movable block rotates along the arc groove.
