The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The specific structure of the pellet casting machine 1 according to the embodiment of the present invention is described below with reference to fig. 1.
As shown in fig. 1, a pellet casting machine 1 according to an embodiment of the present invention includes a pellet injection mold 10, a conveying mechanism 20, a pouring mechanism 30, an electric induction heating module (not shown), and a discharging mechanism 40. The conveying mechanism 20 is a triangular conveyor, and the injection mold 10 is provided on the conveying mechanism 20 for conveyance. The casting mechanism is arranged on the conveying mechanism 20, the casting mechanism is provided with a storage bin 310 for containing molten metal liquid, and the electric induction heating module is used for heating and stirring the molten metal liquid in the storage bin 310. The conveying mechanism 20 can drive the injection mold 10 to circularly convey, when the injection mold 10 is conveyed to the first set position a, the casting mechanism injects molten metal into the injection mold 10, and when the injection mold 10 is conveyed to the second set position B, the discharging mechanism 40 receives metal particles cast by the molten metal in the injection mold 10.
It can be understood that, during the operation of the granule casting machine 1, the conveying mechanism 20 can drive the granule injection mold 10 to circularly convey, and during the conveying process, the molten metal liquid is continuously injected into the granule injection mold 10 and then the metal granules are output, so that the continuous pouring of the granule casting machine 1 is realized. Meanwhile, the electric induction heating module used for heating the molten metal is arranged on the storage bin 310, and the electric induction heating module continuously heats the molten metal, so that the phenomenon that the molten metal is poor in fluidity at low temperature due to low superheat degree of the molten metal is avoided, and the phenomenon that pouring is carried out smoothly cannot be guaranteed. In addition, because the heating module is the electric induction heating module, compare the mode of gas heating, the main component of molten metal solution can not be changed to the electric induction heating module, has guaranteed the qualification nature of metal particle, and because the electric induction heating module has the electromagnetic stirring function, has promoted the come-up of inclusion in the molten metal melt, has improved the purity of metal particle.
According to the utility model discloses grain machine 1 casts, because conveying mechanism 20 can drive annotate grain mould 10 circulation transmission for continuous being poured into molten metal liquid then output metal grain in annotating grain mould 10, realized the continuous pouring of grain machine 1 casts. Meanwhile, as the storage bin 310 is provided with the electric induction heating module for heating the molten metal solution, the electric induction heating module can continuously heat the molten metal solution, so that the temperature of the molten metal solution is ensured, and the phenomenon of solidification and ladle is prevented. In addition, the electric induction heating module can not change the main components of the molten metal solution, so that the qualification of metal particles is ensured, and meanwhile, the electric induction heating module has an electromagnetic stirring function, so that the floating of impurities in the molten metal melt is promoted, and the purity of the metal particles is improved.
In some embodiments, the holding trough 320 is provided at the molten metal outlet of the storage bin 310, thereby reducing heat loss after the molten metal flows out of the storage bin 310, further preventing the occurrence of the ladle-congealing phenomenon, and ensuring smooth proceeding of the cast pellets.
In some embodiments, the pellet casting machine 1 further includes a slurry spraying mechanism 50, and the slurry spraying mechanism 50 sprays the cleaning solution toward the pellet casting mold 10 when the pellet casting mold 10 is transferred to the third set position C. It will be appreciated that as the shot mould 10 passes through the second set position, the metal particles cast from the cooled and solidified molten metal are poured into the discharge mechanism 40, and that there will be a small proportion of metal slag in the shot mould 10, which will affect the uniformity of the metal particles cast next. Thereby, when the shot mold 10 is transferred to the third set position C, the slurry spraying mechanism 50 sprays the cleaning liquid toward the shot mold 10. The cleaning solution can wash away the residual metal slag, so that the particle injection mold 10 is relatively clean when the particle injection mold 10 passes through the first set position A again, and the uniformity of metal particles is ensured.
Specifically, the conveying path of the triangular conveyor includes a first section 210, a second section 220 and a third section 230, the first section 210 extends obliquely upward in the conveying direction, a first set position a is disposed adjacent to the lower end of the first section 210, the second section 220 is disposed below the first section 210, the second section 220 is tilted downward from the upper end of the first section 210 and toward the lower end of the first section 210 in the conveying direction, a second set position B is disposed adjacent to the upper end of the second section 220, a third set position C is disposed adjacent to the lower end of the second section 220, and the third section 230 connects the lower end of the first section 210 and the lower end of the second section 220, respectively.
It will be appreciated that, at a certain horizontal distance between the first setting position a and the second setting position B, the first segment 210 is arranged to extend obliquely upward in the conveying direction, increasing the moving time of the shot moulding tool 10 from the first setting position a to the second setting position B, that is, increasing the solidification time of the molten metal solution, ensuring that the molten metal solution has completely solidified to form metal granules when the shot moulding tool 10 reaches the second setting position B, and thus ensuring the quality of the cast granules of the granule casting machine 1. Similarly, when the vertical distance between the second setting position B and the third setting position C is constant, the second section 220 is inclined downward from the upper end of the first section 210 toward the lower end of the first section 210, so that the moving time of the shot-peening mold 10 from the second setting position B to the third setting position C is increased, and therefore, the situation that residual unsolidified molten metal liquid exists in the shot-peening mold 10 and the molten metal is splashed out during guniting to cause a safety hazard is prevented. In addition, the second section 220 is inclined downwards from the upper end of the first section 210 and towards the lower end of the first section 210, so that the opening of the shot-peening die 10 is arranged downwards after entering the second section 220, and metal particles can fall into the discharging mechanism 40 when the shot-peening die 10 passes through the second setting position B.
It should be noted that the time for which the shot mold 10 is heated is the time from when the shot mold 10 receives the molten metal liquid to when the metal particles fall down to the discharging mechanism 40, and the time for which the shot mold 10 is cooled is the time from when the metal particles fall down to when the metal particles return to receiving the molten metal liquid again. That is, the time that the shot-peening mold 10 is heated is the time that the shot-peening mold 10 moves from the first setting position a to the second setting position B, that is, the time that the shot-peening mold 10 travels in the first section 210, and the time that the shot-peening mold 10 cools is the time that the shot-peening mold 10 returns from the second setting position B to the first setting position a, that is, the time that the shot-peening mold 10 travels in the second section 220 and the third section 230, because the transmission path of the triangular conveyor is a triangle, the length of the first section 210 is less than the sum of the second section 220 and the third section 230, that is, the time that the shot-peening mold 10 is heated is less than the time that the shot-peening mold 10 cools, so that the shot-peening mold 10 is prevented from being damaged by overheating during the shot-peening mold process, and the service life.
Optionally, the angle α between the second section 220 and the horizontal plane satisfies the relationship 20 ° ≦ α ≦ 60 ° to thereby ensure that the length of the second section 220 is such that no molten metal liquid is present inside the shot moulding tool 10 when moved to the third set position C, although the user may adjust the size of α as desired.
Optionally, the length ratio between the second segment 220 and the third segment 230 is N, N satisfying the relation: n is more than or equal to 0.2 and less than or equal to 0.8. Therefore, the sufficient cooling time after the slurry spraying of the grain casting die is ensured, the overheating damage of the grain injection die 10 is further prevented, and the size of N can be adjusted by a user according to actual needs.
In some alternative embodiments, the triangular conveyor includes a plurality of drive wheels and a drive chain supported on the plurality of drive wheels to form a triangle, at least one of the drive wheels being a drive wheel 240. This ensures that the cam conveyor can maintain a triangular conveying path and that the injection mold 10 can be cyclically conveyed between the first setting position a, the second setting position B, and the third setting position C.
Specifically, the plurality of driving wheels further include a driven wheel 250 and a tension wheel 260, the driving wheel located at the junction of the first section 210 and the second section 220 is a driving wheel 240, the driving wheel located at the junction of the second section 220 and the third section 230 is the driven wheel 250, and the driving wheel located at the junction of the third section 230 and the first section 210 is the tension wheel 260. Therefore, the stable transportation of the shot-injection mould 10 is ensured, and the phenomenon that the molten metal solution is splashed due to the shaking of a transmission chain in the transportation process is avoided. It should be additionally noted that, in the embodiment of the present invention, the positions of the driving wheel 240, the driven wheel 250 and the tension wheel 260 are not limited to the above manner, and the positions of the three driving wheels can be changed at will, which is not illustrated herein.
In some embodiments, the discharging mechanism 40 includes a discharging box 410, a discharging hole 411 is formed at the bottom of the discharging box 410, and the discharging mechanism 40 further includes a discharging plate 420 drawably disposed at the discharging hole 411. It will be appreciated that when the molten metal solution is poured, all of the metal particles are transferred to the tap box 410, and when the tap box 410 is to be filled, the tap plate 420 is opened to allow the metal particles to fall into the ton bag below the conveyor mechanism 20, and when the ton bag is full, the metal particles are transferred by the crane to be weighed and stored in the product storage. Therefore, the phenomenon that the discharging box 410 is filled to cause the stopping and discharging of the granule casting machine 1 is avoided, and the granule casting efficiency of the granule casting machine 1 is further improved.
In some alternative embodiments, the electric induction heating module comprises an induction coil. The induction coil is adopted for heating, so that the molten metal liquid can be heated, the stable superheat degree of the molten metal liquid is kept, the ladle condensation is avoided, and the smooth casting is ensured. Meanwhile, the heating mode is not in direct contact with the molten metal liquid, and the induction coil has a magnetic stirring function, so that the main components of the molten metal solution are not influenced, partial impurities in the molten metal solution can be removed, and the purity of the molten metal solution is improved.
