Description

Technical Field

[0001] The present invention relates to the technical field of pouring, and specifically relates to a multi-stage pouring device with a buffering function. Background Art

[0002] In the pouring process of molten metal, the air in the casting box is exhausted, and then the refined molten metal is injected into the mold through a pouring cup and a pouring port, and after cooling and shaping, the molten metal is shaped to form a casting.

[0003] In the common molten metal pouring process, a pouring box is often directly aligned with the pouring cup for pouring. Since both the molten metal and the pouring device are in a high-temperature state, special pouring equipment has been designed for the pouring process. However, when pouring starts, due to the poor control of the relationship between the pouring volume and the liquid inflow volume at the pouring port, when the pouring volume is greater than the inflow volume, the molten metal is likely to overflow, resulting in no buffering of the liquid volume during the continuous pouring process. Therefore, not only the waste of metal is caused, but also the filling effect is poor. This phenomenon has become an urgent problem for those in this field to solve. Summary of the Invention

[0004] When a buffering device is added during the pouring process, when the relationship between the pouring volume and the liquid inflow volume is difficult to control, the pouring volume is buffered to achieve a better pouring effect.

[0005] The purpose of the present invention is to provide a multi-stage pouring device with a buffering function to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A multi-stage pouring device with a buffering function, including a central control terminal and a remote control box. The central control terminal is installed inside the remote control box and is used to execute the pouring process in an orderly manner. On one side of the remote control box, there is a pouring component and a buffering component;

The interior of the liquid tank is filled with molten metal. The first rotating block is hemispherical and hollow inside, and through holes are respectively formed at the edges of the first rotating block adjacent to the outflow port and the inflow port. The through holes are semicircular.

[0010] The present invention further illustrates that a plurality of the casting boxes are on the same horizontal line below the pouring pipe, and the lower end of the diversion pipe is located above the pouring pipe.

[0011] The present invention further illustrates that one side of the upper end of the first pouring cup is connected with a heat preservation pipe. A pressure detector is installed on the side of the heat preservation pipe close to the first pouring cup. The other end of the heat preservation pipe is connected with a suction pump and a recovery tank.

[0012] The present invention further illustrates that a moving assembly is further arranged on one side of the remote control box.

The upper surface of the slide seat is fixedly connected with the first bracket through bolts.

[0013] The present invention further illustrates that the central control end includes a pouring operation module and an adjustment module. The pouring operation module is used to execute the pouring process and simultaneously judge the size of the flow rate. When the pouring flow rate is large, the pouring flow rate is reduced to prevent overflow when too much molten metal is poured. The pouring operation module includes a parameter starting unit, a heating unit, a diversion unit, a moving unit, a pressure measuring unit, and a flow rate judging unit. The adjustment module is used to receive adjustment instructions.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, through the flow-through box and the diversion pipe, a primary buffering effect is achieved during the pouring process of the molten metal, avoiding direct injection of the liquid into the pouring pipe or the first sprue cup by the liquid tank, resulting in the pouring volume being easily greater than the inflow volume of the sprue cup, causing serious overflow of the liquid in the first sprue cup, and thus leading to poor filling effect and a large waste of molten metal.

[0017] By setting a pressure detector, a flow rate judgment module, and an adjustment module, it is possible to judge the size of the pouring flow rate and the corresponding pouring state based on the overflowing molten metal at the upper end of the first sprue cup. Then, by adjusting the pouring flow rate and replacing the sprue cup, an intelligent buffering effect for the pouring of molten metal is achieved, improving the filling effect in the casting box.

The moving component is used to implement the moving process of some components in the pouring component.

[0027] The pouring component includes a set of first brackets 8. A liquid tank 10 is arranged between the set of first brackets 8. The inside of the liquid tank 10 is filled with molten metal. Both sides of the liquid tank 10 are fixedly connected with rotating rods, and the other ends of the rotating rods are connected to the first brackets 8 by bearings. A second motor 9 is bolted to the outer wall of one of the first brackets 8. The output end of the second motor 9 is located inside the first bracket 8 and fixedly connected to the end of the rotating roller inside it. The front wall of the first bracket 8 is fixedly provided with a second bracket 11 and a third bracket 12 from top to bottom in sequence. A flow-through box 15 is arranged in the middle of the second bracket 11. A pouring pipe 13 is arranged in the middle of the third bracket 12. A plurality of casting boxes 14 are arranged below the pouring pipe 13. The plurality of casting boxes 14 are on the same horizontal line, which is convenient for the liquid tank 10 to pour into the inside of the plurality of casting boxes 14 along the horizontal line direction. A guide pipe 16 is communicated with the front wall of the flow-through box 15. The lower end of the guide pipe 16 is located above the pouring pipe 13. When the output end of the second motor 9 starts and drives the liquid tank 10 to rotate at a certain angular velocity and tilt, the pouring amount of molten metal entering the flow-through box 15 can be controlled by adjusting the angular velocity. The heated molten metal flows into the inside of the flow-through box 15, and then enters the inside of the casting box 14 through the guide pipe 16 and the pouring pipe 13 to carry out the pouring and forming process;

[0028] A mold is arranged inside the casting box 14. The mold is used for the molten metal injected to be formed. A first pouring cup 29 and a second pouring cup 30 are arranged above the casting box 14. One side of the upper end of the first pouring cup 29 is connected with a heat preservation pipe.

[0029] Heating pipes are installed on the inner walls of the liquid tank 10 and the flow-through box 15. The heating pipes are electrically connected to an external power supply to respectively carry out the heating and heat preservation processes of the molten metal, improve the fluidity of the liquid, and improve the filling effect.

[0030] The buffering component includes a rotating component and a flow control component. The rotating component includes a third motor 19 ，The third motor 19 is fixed inside the second bracket 11. A connecting rod 4 is fixedly connected to the output end of the third motor 19. The connecting rod 4 penetrates through the flow-through box 15 and is fixedly connected to the inside of the flow-through box 15. The flow control component includes a detection box 20. The detection box 20 is fixed to the inner wall of the flow-through box 15 on the side close to the diversion pipe 16. The connection part where the connecting rod 4 penetrates through the flow-through box 15 and is connected to the second bracket 11 is a bearing connection;

[0031] An outflow port 21 and an inflow port 22 are formed on the detection box 20, which are used to allow the molten metal in the flow-through box 15 to enter the inside of the diversion pipe 16 through the inflow port 22 and the outflow port 21. Both the outflow port 21 and the inflow port 22 are circular. The flow control component further includes a fourth motor 23 fixed to the side wall of the flow-through box 15. A support rod 24 is fixedly connected to the output end of the fourth motor 23. The support rod 24 penetrates through the inside of the detection box 20, and the connection part between the support rod 24 and the detection box 20 is a bearing connection. The middle part of the support rod 24 is partitioned, and a first rotating block 25 is fixedly connected to the partitioned part. The first rotating block 25 is hemispherical and hollow inside. Through holes are respectively formed at the edges of the first rotating block 25 adjacent to the outflow port 21 and the inflow port 22. The through holes are semi-circular. The initial state of the first rotating block 25 is that the through holes on both sides thereof are completely communicated with the outflow port 21 and the inflow port 22. The molten metal enters the inside of the diversion pipe 16 through the inflow port 22, the two through holes, and the outflow port 21, realizing the liquid transmission of the molten metal.

[0032] The moving component includes a slide rail 1. The slide rail 1 is bolted to the ground. A slide seat 7 is slidably connected inside the slide rail 1. The slide seat 7 is T-shaped. The upper surface of the slide seat 7 is fixedly connected to the first bracket 8 by bolts. A nut is fixedly installed inside the slide seat 7. A lead screw 6 is rotatably connected inside the nut. The lead screw 6 and the nut are arranged as a ball screw nut structure. When the lead screw 6 rotates, it drives the nut and the slide seat 7 to move along the direction of the slide rail 1. One end of the slide rail 1 is provided with a first motor 3, and the other end of the slide rail 1 is provided with a support block 5. One end of the lead screw 6 is fixedly connected to the output end of the first motor 3, and the other end of the lead screw 6 is in bearing connection with the inside of the support block 5;

[0033] A remote control box 2 is arranged on one side of the slide rail 1. The remote control box 2 is electrically connected to electrical components such as the first motor 3, the second motor 9, the third motor 19, the fourth motor 23, the heating pipe, and the suction pump by electrical signals. A power supply is arranged inside the remote control box 2, which is used to provide a power source for the operation of each component.

[0034] Inside the remote control box 2, a central control terminal is provided. The central control terminal includes a pouring operation module and an adjustment module. The pouring operation module is used to execute the pouring process and simultaneously judge the size of the flow rate. When the pouring flow rate is large, it reduces the pouring flow rate to prevent excessive molten metal from overflowing above the first pouring cup 29. The pouring operation module includes a parameter startup unit, a heating unit, a diversion unit, a moving unit, a pressure measurement unit, and a flow rate judgment unit. The adjustment module is used to receive adjustment instructions. The adjustment module is electrically connected to a flow control unit, and the moving unit is electrically connected to the adjustment module;

[0035] The parameter startup unit is used to set the operating parameters in the pouring process. The heating unit is electrically connected to two groups of heating tubes. The diversion unit is electrically connected to the second motor 9. The moving unit is electrically connected to the first motor 3. The pressure measurement unit is electrically connected to a pressure detector. The flow rate judgment unit is signal-connected to the pressure measurement unit. The flow control unit is electrically connected to the fourth motor 23.

[0036] In this example, an operator sets the operating parameters at the central processing terminal. The operating parameters include the rotational angular velocity of the second motor 9, the preheating temperature W of the heating tubes in the liquid tank 10 0 , the heat preservation temperature w of the heating tubes in the flow-through box 15 0 , the operating time T of each group of the first motor 3 0 and the residence time t 0 . The pouring process is started through the parameter startup unit. The diversion unit controls the second motor 9 to operate at the set angular velocity and drives the liquid tank 10 to rotate slowly. The molten metal in the liquid tank 10 enters the inside of the flow-through box 15, and successively passes through the inflow port 22, the through-hole on the first rotating block 25, the outflow port 21, and then enters the inside of the pouring pipe 13 under the guiding action of the diversion pipe 16. The lower end of the pouring pipe 13 is aligned with the first pouring cup 29, and the casting process is carried out on the mold through the first pouring cup 29. The state of the first rotating block 25 is as Figure 3 shown, that is, the through-hole on the first rotating block 25 is completely communicated with the inflow port 22 and the outflow port 21, so that the molten metal completely enters the inside of the diversion pipe 16 through the outflow port 21, and the fluidity of the molten metal is good and no bonding phenomenon occurs. Therefore, the above fluid flow state is set as the initial diversion state;

[0037] Through the settings of the flow-through box 15 and the diversion pipe 16, a primary buffering effect is achieved during the pouring process of the molten metal, avoiding directly injecting liquid from the liquid tank 10 into the pouring pipe 13 or the first pouring cup 29, resulting in the pouring volume being easily greater than the amount that can pass through the pouring cup, causing serious overflow of the liquid in the first pouring cup 29, and thus leading to poor filling effect and a large amount of waste of molten metal;

[0038] The moving unit receives the set operating time T 0 and the residence time t 0Data, and perform timed movement of the sliding seat 7 according to the set time data. Specifically, when the first casting box 14 completes the pouring process, the output end of the first motor 3 drives the lead screw 6 to rotate for T 0 , the lead screw 6 rotates and drives the sliding seat 7 to move along the direction of the slide rail 1, and under the action of T 0 , the sliding seat 7 moves to the second casting box 14, and the pouring pipe 13 is aligned above the first pouring cup 29 on the second casting box 14, facilitating the pouring process inside the second casting box 14, and the time for the sliding seat 7 to stay at the second casting box 14 is t 0 , during t 0 , reserve sufficient time for the casting box 14 to complete the pouring process, and so on, so as to complete the pouring process of all casting boxes 14.

[0039] The heat preservation pipe at the upper end of the first pouring cup 29 is used to divert and recover the overflow molten metal that cannot flow orderly into the casting box 14, improving the cleanliness of the surface of the casting box 14.

[0040] When performing the pouring process of the casting box 14, the flow rate judgment of the molten metal pouring process is carried out at the same time. The specific operation steps of the central processing end are as follows:

[0041] S1: Set operating parameters in the central control end in advance, and then the parameter startup unit starts the pouring process;

[0042] S2: When the pouring process is started, the flowing liquid maintains the initial diversion state, and the molten metal is poured into the first pouring cup 29 through the pouring pipe 13. At the same time, the pressure measurement unit detects the pressure of the molten metal flowing in the heat preservation pipe through the pressure detector, denoted as the molten metal pressure value F, where the maximum pressure limit value of the pressure detector is set as F max ;

[0043] S3: The flow rate judgment unit compares the molten metal pressure value F with F max to obtain the ratio coefficient a, and at the same time, the flow rate judgment unit judges the pouring state according to the size of a. Usually, the result is set as normal and abnormal pouring states, and the judgment result is transmitted to the adjustment module. When the pouring state is normal, it enters S5. When the pouring state is abnormal, it enters S4;

[0044] S4: The adjustment module further adjusts the operating states of the flow control unit and the moving unit according to the abnormal state to improve the filling effect in the casting box 14, and then enters S6;

[0045] S5: After the adjustment module receives the result of normal pouring state, it directly enters S6;

[0046] S6: Pour the next casting box 14, and repeat S2 - S5 until the pouring process of all casting boxes 14 is completed.

[0047] The specific judgment process of S3 is that the range of the ratio coefficient a is 0 ≤ a ≤ 1, and the discrimination range is preset manually. When 0 ≤ a ≤ 0.5, it is set that the pouring state is normal; when 0.5 < a ≤ 1, it is set that the pouring state is abnormal.

[0048] The further content of S4 is as follows:

[0049] S41: When the adjustment module obtains that 0.5 < a ≤ 1, the pouring state is abnormal, and the greater the value of a, the more serious the abnormal degree. The adjustment module takes adjustment measures according to the abnormal degree.

[0050] S42: When 0.5 < a ≤ 0.8, it is set that the abnormal degree of pouring is moderate. The flow control unit controls the fourth motor 23 to start, so that the first rotating block 25 rotates a certain angle. The rotation angle is positively correlated with the value of a, so that the flow rate of the molten metal flowing out of the flow-through box 15 is reduced, and the injection amount into the first pouring cup 29 is buffered to prevent more molten metal from overflowing.

[0051] S43: When the adjustment module still receives the data of 0.8 < a ≤ 1 under the adjustment of S42, it is set that the abnormal degree of pouring is high. At this time, the flow control unit controls the fourth motor 23 to start until the first rotating block 25 blocks the outflow port 21, and the diversion pipe 16 stops diverting. The central control end controls the suction pump to start, and sucks the molten metal overflowing inside and outside the heat preservation pipe and the first pouring cup 29, so as to prevent the remaining molten metal flowing down in the diversion pipe 16 from overflowing to the surface of the casting box 14. After the suction is completed, the moving unit controls the pouring pipe 13 to move to the second pouring cup 30, and the flow control unit then makes the outflow port 21 pass the liquid. The molten metal is poured from the second pouring cup 30 through the diversion pipe 16 and the pouring pipe 13 for multi-gate pouring, so as to achieve the pouring buffering effect and improve the filling quality. Among them, the time for the moving unit to control the pouring pipe 13 to move above the second pouring cup 30 and pour is pre-designed within the residence time t 0 ;

[0052] By setting a pressure detector, a flow rate judgment module and an adjustment module, the size of the pouring flow rate and the corresponding pouring state are judged according to the molten metal overflowing at the upper end of the first pouring cup 29. Then, by adjusting the pouring flow rate and replacing the pouring cup, the intelligent buffering effect of the molten metal pouring is realized, and the filling effect in the casting box 14 is improved.

[0053] In the above embodiment, the pressure detector 32 can be replaced with a flow sensor and disposed at the same position, or on the heat preservation pipe closer to the upper end of the first pouring cup 29. Once the molten metal enters the heat preservation pipe, the flow sensor receives the flow data of the molten metal in the pipe and transmits it to the central processing end. After the central processing end receives the flow signal, i.e., the overflow signal, the flow control unit controls the fourth motor 23 to start and perform the flow control process. However, when using the pressure detector 32 to compare the pressure data, further flow judgment and setting can be performed. The rotation angle of the first rotating block 25 can be directly converted according to the change of the a value to obtain an accurate value, so that the flow rate of the molten metal is reduced, and the injection amount in the first pouring cup 29 is intelligently buffered. At the same time, it is ensured that there is enough molten metal in the first pouring cup 29 for injection to prevent the situation that the injection amount of the molten metal in the first pouring cup 29 is insufficient after the flow control process ends.

[0054] Embodiment Two

[0055] On the basis of Embodiment One, the following structure is added: a flow meter 17 is installed on the diversion pipe 16 for detecting the flow rate of the molten metal flowing through the diversion pipe 16.

[0056] The pouring operation module further includes an adhesion judgment unit, the adjustment module further includes a rotation unit, the adjustment module is also electrically connected to the heating unit, the adhesion judgment unit is signal-connected to the flow meter 17, and the rotation unit is electrically connected to the third motor (19).

[0057] The buffer assembly not only controls the flow rate of the molten metal in Embodiment One, but also can judge the adhesion degree of the molten metal. The specific judgment process is as follows:

[0058] When there is no adhesion phenomenon in the molten metal, that is, in the initial diversion state, through the rotation of the first rotating block 25, the adhesion judgment module obtains the corresponding flow rate of the molten metal in the diversion pipe 16, denoted as the standard molten metal flow rate Q i , i is the rotation angle value of the first rotating block 25, and Q i is the flow rate value detected by the flow meter 17 when the first rotating block 25 rotates by the i value without adhesion phenomenon. However, due to the accumulation of the molten metal in the flow-through box 15 and the influence of the environmental temperature, adhesion phenomena will occur inside the flow-through box 15 and the liquid box 10, which will cause the flow rate value detected by the flow meter 17 to decrease. The adhesion judgment unit records the actual flow rate value detected by the flow meter 17 as the actual flow rate value q. The adhesion judgment unit judges the adhesion degree of the molten metal through the q / Q i value, divides the adhesion degree into no adhesion degree, low adhesion degree, and high adhesion degree, and adjusts the corresponding process according to the adhesion degree to ensure the normal output of the liquid flow rate.

[0059] When the adjustment module receives that the bonding degree is none, it indicates that there is no metal liquid bonding phenomenon, and no adjustment process is required;

[0060] When the adjustment module receives that the bonding degree is low, it indicates that there is a slight bonding phenomenon of the metal liquid. The rotation unit controls the fourth motor 23 to start and makes the flow-through box 15 rotate by a certain angle, that is, the injection flow angle is adjusted, so that the flow rate in the diversion pipe 16 increases to ensure the normal output of the metal liquid into the casting box 14;

[0061] When the adjustment module receives that the bonding degree is high, it indicates that there is a serious bonding phenomenon of the metal liquid. The heating unit controls two groups of heating tubes to heat up, raising the liquid temperature and improving the fluidity of the liquid;

[0062] The injection flow angle and temperature are adjusted by judging the bonding degree, improving the flow stability of the metal liquid in the pouring process.

[0063] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0064] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.

6. A multi-stage pouring device with a buffering function according to claim 5, wherein: The central control end includes a pouring operation module and an adjustment module. The pouring operation module is used to execute the pouring process and simultaneously judge the size of the flow rate. When the pouring flow rate is large, the pouring flow rate is reduced to prevent overflow when too much molten metal is poured. The pouring operation module includes a parameter startup unit, a heating unit, a diversion unit, a moving unit, a pressure measuring unit, and a flow rate judging unit. The adjustment module is used to receive adjustment instructions. The adjustment module is electrically connected to a flow control unit, and the moving unit is electrically connected to the adjustment module.

7. A multi-stage pouring device with a buffering function according to claim 6, wherein: The specific operation steps of the central processing end are as follows: S1: Set the operation parameters in the central control end in advance, and then the parameter startup unit starts the pouring process; S2: When the pouring process is started, the flowing liquid maintains the initial diversion state, and the molten metal is poured into the first pouring cup (29) through the pouring pipe (13). At the same time, the pressure measurement unit detects the pressure of the molten metal flowing in the heat preservation pipe through the pressure detector (32), which is recorded as the molten metal pressure value F. The maximum pressure limit of the pressure detector (32) is set as F max ; S3: The flow rate judgment unit compares the molten metal pressure value F with F max to obtain the ratio coefficient a, and meanwhile, the flow rate judgment unit judges the pouring state according to the magnitude of a. Usually, the result is set to normal and abnormal pouring states, and the judgment result is transmitted to the adjustment module. When the pouring state is normal, it enters S5; when the pouring state is abnormal, it enters S4; S4: The adjustment module further adjusts the pouring flow rate and replaces the pouring cup according to the abnormal state to achieve the intelligent buffering effect of molten metal pouring, improve the filling effect in the casting box (14), and then enter S6; S5: After the adjustment module receives the normal result of the pouring state, it directly enters S6; S6: Pour the next casting box (14), and repeat S2-S5 until the pouring process of all casting boxes (14) is completed.

8. A multi-stage pouring device with a buffering function according to claim 7, wherein: The initial diversion state is that the through ports on both sides of the first rotating block (25) are completely communicated with the outflow port (21) and the inflow port (22), and the fluidity of the molten metal is good without any bonding phenomenon. The operating parameters include the rotational angular velocity of the second motor (9), the preheating temperature of the heating pipes in the liquid tank (10), the heat preservation temperature of the heating pipes in the flow-through box (15), and the operating time T of each group of the first motor (3) 0 and the residence time t 0 , during t 0 , sufficient time is reserved to complete the pouring process of the casting box (14).

The connecting rod (4) is fixedly connected inside the flow-through box (15). The third motor (19) is fixed inside the second bracket (11).

10. A multi-stage pouring device with a buffering function according to claim 9, wherein: When there is no bonding phenomenon in the molten metal, that is, in the initial diversion state, by rotating the first rotating block (25), the bonding judgment module obtains the corresponding molten metal flow rate in the diversion pipe (16), denoted as the standard molten metal flow rate Q i , where i is the rotation angle value of the first rotating block (25), and Q i is the flow rate value detected by the flowmeter (17) when the first rotating block (25) rotates by i value without bonding phenomenon. However, due to the accumulation of molten metal in the flow-through box (15) and the influence of the ambient temperature, bonding phenomena will occur inside the flow-through box (15) and the liquid tank (10). As a result, the flow rate value detected by the flowmeter (17) will decrease. The bonding judgment unit records the actual flow rate value detected by the flowmeter (17) as the actual flow rate value q. The bonding judgment unit judges the bonding degree of the molten metal through the q / Q i value, classifies the bonding degree into no bonding degree, low bonding degree, and high bonding degree, and makes corresponding process adjustments according to the bonding degree to ensure the normal output of the liquid flow rate.
