Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, in particular to a production and processing device for heat-resistant steel castings. Background Art

[0002] Passivation is a corrosion protection process for metal parts and components. It involves different metals, alloys and even carbon steel. The passivation process can build an anti-oxidation layer on the surface of the parts and dissolve the burrs on the surface of the metal parts, making the metal surface cleaner. Under the protection of the oxide layer, the metal material performs more stably in various environments, thereby achieving an excellent service life.

[0003] Publication number CN115772665A describes a heat-resistant steel casting production and processing device. A dual-shaft motor drives a crushing shaft and a spoiler shaft to crush large particles in the passivation solution. The crushed particles are then collected by coarse and fine screens before flowing into a liquid storage tank. This device can promptly remove impurities from the passivation solution.

[0004] However, during use, the box is relatively closed, and although air can circulate, the effect is poor, making it difficult to dry water stains on the casting surface and slow in efficiency. In addition, the outlet height of the liquid outlet pipe is higher than the coarse filter setting, and the passivation liquid contains impurities when it flows back, affecting the recycling of the passivation liquid.

[0013] The drying component includes a fan and a nozzle. The fan is installed on one side of the bracket. The nozzle is connected to the air outlet of the fan. The other side of the nozzle is opened toward the placement tray.

[0014] Preferably, the driving mechanism comprises: a servo motor, the servo motor being horizontally mounted on the top of the transverse plate;

[0015] A connecting shaft is fixedly connected to the inner center of the placement plate. The connecting shaft vertically and upwardly passes through the bracket and the cross plate in sequence. The connecting shaft is connected to the servo motor through a bevel gear set.

[0016] Preferably, an extension tube is nested on the outside of the nozzle, and the outer diameter of the extension tube is consistent with the opening diameter of the air guide tube;

[0017] The extension tube is engaged with the nozzle through a thread, and the outer side surface of the extension tube is provided with a step;

[0018] The nozzle is perpendicular to the outer peripheral surface of the placement plate.

[0019] Preferably, the placement tray is a box-type structure with an open top, the surface of the placement tray is hydrophobic, the side walls of the placement tray are provided with strip-shaped through holes, and the bottom surface of the placement tray is provided with drainage holes;

[0020] The top of the placement tray is fixedly connected with a hanging ring.

[0021] Preferably, the air ducts are distributed radially with the center of the placement disk as the focus.

[0022] Preferably, a baffle is fixedly connected to the bottom of the air guide tube, and the diameter of the baffle is consistent with the diameter of the placement tray;

[0023] The drain hole on the surface of the placement plate is arranged on one side of the air guide pipe.

[0024] Preferably, the filter assembly includes a conical bucket, which is slidably arranged in the vertical direction inside the passivation box, and the bottom of the conical bucket includes a circular tube, and an inverted "T"-shaped guide column is fixed to the bottom of the circular tube;

[0025] A filter screen is nested on the outer side of the guide column, and the diameter of the filter screen is larger than the bottom opening diameter of the circular tube; and a buoyancy box is fixedly connected to the bottom of the filter screen.

[0026] Preferably, a limiting ring is fixedly connected to the top of the filter screen, and the outer diameter of the limiting ring is the same as the bottom opening diameter of the circular tube.

[0027] Preferably, a gas spring is fixedly installed at the bottom of the conical bucket, and the other end of the gas spring is fixed to the inner bottom end of the passivation box.

[0028] Preferably, the inclined surface of the conical bucket is hinged with a rotating shaft, and the rotating shaft is arranged directly below the placement plate.

[0029] Compared with the prior art, the present invention has at least the following beneficial effects:

[0030] In the above scheme, by setting a servo motor, a connecting shaft and a placement plate, when the passivation treatment is completed, the hydraulic cylinder drives the horizontal plate upward to separate the casting from the passivation liquid. The casting rises above the liquid level of the passivation liquid, and the servo motor drives the connecting shaft and the placement plate to rotate. Under the action of centrifugal force, the passivation liquid on the surface of the casting is thrown off, and the passivation liquid on the surface of the casting can be quickly reduced.

[0031] In the above scheme, by setting up a fan, a nozzle and an extension tube, when most of the passivation liquid on the surface of the casting is thrown away, the placement plate continues to move upward until it enters the blowing range of the fan, and the nozzle can concentrate the airflow to blow to the placement plate to dry the casting inside the placement plate. The evaporation of the passivation liquid on the surface of the casting is accelerated by air convection to speed up the drying efficiency. The nozzle and the extension tube cooperate, and the extension tube can be connected to the opening position of the air duct. The extension tube fits tightly to the opening position of the air duct to avoid air leakage, so that the airflow ejected from the nozzle is fully utilized, thereby accelerating the drying efficiency of the bottom of the casting.

[0032] In the above scheme, a conical bucket, a circular tube, a guide column, a filter, a float, a limit ring, a gas spring and a rotating shaft are set. During the downward process of the placement disk, it abuts against the surface of the conical bucket and drives the conical bucket downward. The float is upward due to the buoyancy of the passivation liquid, and the filter fits tightly to the bottom surface of the circular tube. At the same time, the passivation liquid enters the circular tube after being filtered by the filter, thereby filtering the passivation liquid. The filtered passivation liquid reacts with the casting to passivate and reduce the adhesion of impurities to the surface of the casting. After the passivation reaction is completed, the placement disk is moved upward. Under the action of the float, the conical bucket is reset upward, so that the impurities generated by the passivation reaction are precipitated into the inside of the circular tube for temporary storage, so as to reduce the impurities caused by the flow of the passivation liquid, which is conducive to continuous production.

[0033] In the above scheme, a gas spring is provided to guide the displacement of the conical bucket, and can float the conical bucket together with the float box to the liquid surface of the passivation liquid when the conical bucket is reset. Under the action of the gravity of the float box itself, the filter screen is separated from the circular tube. At the same time, the passivation liquid in the circular tube flows downward and impacts the filter screen. Impurities on the surface of the filter screen can fall into the passivation box for precipitation, thereby circulating, ensuring that during continuous processing, impurities in the passivation liquid can be separated from the casting, accelerating the processing efficiency while ensuring the passivation processing quality.

DETAILED DESCRIPTION

[0045] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4The heat-resistant steel casting production and processing equipment shown in the embodiment of the present invention includes a passivation box 1, a bracket 101 is fixedly connected to the top of the passivation box 1, a placement tray 2 is provided on the top of the passivation box 1, and the side wall of the placement tray 2 is hollowed out;

[0046] An air duct 201 is provided at the bottom of the placement tray 2. One end of the air duct 201 is open, and the top surface of the air duct 201 coincides with the bottom surface of the placement tray 2. A spray hole is provided at the top of the air duct 201.

[0047] A hydraulic cylinder 102 is installed on one side of the bracket 101, and a horizontal plate 103 is installed on the top of the hydraulic cylinder 102. The horizontal plate 103 is hinged to the placement plate 2;

[0048] A driving mechanism is installed on the top of the horizontal plate 103, and the driving mechanism is used to drive the placement plate 2 to rotate;

[0049] The passivation box 1 further comprises: a filter assembly, the filter assembly being used to filter the passivation liquid;

[0050] The drying assembly includes a fan 3 and a nozzle 301. The fan 3 is installed on one side of the bracket 101. The nozzle 301 is connected to the air outlet of the fan 3. The other side of the nozzle 301 is opened toward the placement tray 2.

[0051] Before the passivation treatment, the casting is placed on the top of the placement tray 2, and the hydraulic cylinder 102 drives the horizontal plate 103 to move downward, so that the casting is immersed in the passivation liquid in the passivation box 1. After the passivation treatment is completed, the hydraulic cylinder 102 drives the horizontal plate 103 upward to separate the casting from the passivation liquid. The casting moves upward to above the liquid level of the passivation liquid, and the placement tray 2 is driven by the driving mechanism to rotate. Under the action of centrifugal force, the passivation liquid on the surface of the casting is thrown off, and the passivation liquid on the surface of the casting can be quickly reduced;

[0052] The casting does not leave the passivation box 1 when it is spun dry, so the passivation liquid spun out can be collected by the passivation box 1, which is conducive to recycling and reducing the waste of passivation liquid. At the same time, impurities in the passivation liquid can use this gap time to settle;

[0053] When most of the passivation liquid on the casting surface is thrown away, the placement tray 2 continues to move upward until it enters the blowing range of the fan 3. The nozzle 301 can concentrate the air flow to blow towards the placement tray 2 to dry the casting inside the placement tray 2. The convection of air accelerates the evaporation of the passivation liquid on the casting surface, thereby improving the drying efficiency.

[0054] During this process, the placement tray 2 can still be continuously displaced up and down and rotated at the same time so that the airflow can evenly act on the outer surface of the casting, preferably with full coverage of the outer surface of the casting. When the nozzle 301 is opened on one side of the air duct 201, the airflow blown out from the nozzle 301 can quickly enter the air duct 201 and be blown out from the top opening of the air duct 201 to quickly dry the bottom surface of the casting and dry the passivation liquid remaining at the bottom end of the placement tray 2. During this process, the air in the placement tray 2 is quickly replaced, thereby forming a relatively dry environment in the groove space of the placement tray 2, so as to facilitate the evaporation of the passivation liquid, accelerate the drying speed, and improve the processing efficiency.

[0055] In this embodiment, Figure 3 As shown; the driving mechanism includes: a servo motor 4, the servo motor 4 is horizontally mounted on the top of the horizontal plate 103;

[0056] A connecting shaft 202 is fixedly connected to the inner center of the placement plate 2. The connecting shaft 202 vertically passes through the bracket 101 and the cross plate 103 in sequence. The connecting shaft 202 is connected to the servo motor 4 through a bevel gear set.

[0057] The servo motor 4 drives the connecting shaft 202 to rotate, causing the placement plate 2 to rotate. During the passivation process, the passivation liquid in the passivation box 1 can be stirred, promoting the flow of the passivation liquid and making the passivation liquid evenly distributed;

[0058] During the flow of the passivation liquid, the passivation reaction occurs synchronously. The impact force of the flow of the passivation liquid can strip off impurities on the surface of the casting, while ensuring good contact between the casting and the passivation liquid, ensuring the passivation quality, and having the effect of efficient and rapid passivation.

[0059] like Figure 4 、 Figure 5 As shown, an extension tube 302 is nested outside the nozzle 301, and the outer diameter of the extension tube 302 is consistent with the opening diameter of the air guide tube 201;

[0060] The extension tube 302 is engaged with the nozzle 301 through a thread, and the outer side surface of the extension tube 302 is provided with a step;

[0061] The nozzle 301 is perpendicular to the outer peripheral surface of the placement plate 2;

[0062] The nozzle 301 cooperates with the extension tube 302, and the extension tube 302 can be connected to the opening position of the air duct 201. The extension tube 302 fits tightly to the opening of the air duct 201 to avoid air leakage, so that the airflow ejected from the nozzle 301 can be fully utilized, thereby accelerating the drying efficiency of the bottom of the casting.

[0063] like Figure 4As shown, the placement tray 2 is a box-type structure with an open top. The surface of the placement tray 2 is hydrophobic, the side walls of the placement tray 2 are provided with strip-shaped through holes, and the bottom surface of the placement tray 2 is provided with drainage holes.

[0064] The top of the placement tray 2 is fixedly connected with a hanging ring 203;

[0065] The surface of the placement plate 2 is provided with a hydrophobic layer, which is not easy to leave droplets of passivation liquid. At the same time, the strip-shaped through-hole can cooperate with the nozzle 301, so that the air flow can directly act on the side of the casting, which has a good drying effect on the side of the casting;

[0066] Under the action of the drainage holes at the bottom of the placement tray 2, the passivation liquid on the surface of the casting can be quickly drained, and the vertically downward drainage holes can allow the passivation liquid to flow back into the passivation box 1 for recycling, saving resources;

[0067] The lifting ring 203 is used to pass the cable to further fix the casting, thereby achieving a good fixing effect, reducing the displacement and shaking of the casting, and ensuring the stability of the casting during the passivation treatment.

[0068] like Figure 4 As shown, the air ducts 201 are radially distributed with the center of the placement tray 2 as the focus;

[0069] The air ducts 201 are evenly distributed on the bottom surface of the placement tray 2 and can evenly discharge air upward to quickly replace the moist air in the placement tray 2. The dry air wraps the casting, thereby ensuring that the surface of the casting can be fully dried.

[0070] like Figure 4 As shown in FIG. 2 , a baffle 204 is fixedly connected to the bottom of the air duct 201, and the diameter of the baffle 204 is consistent with the diameter of the placement tray 2;

[0071] The drain hole on the surface of the placement tray 2 is opened on one side of the air guide pipe 201;

[0072] The baffle 204 at the bottom of the air duct 201 has a protective effect on the air duct 201. When the placement tray 2 moves downward, it can prevent foreign objects from squeezing the placement tray 2 and the air duct 201, thereby ensuring the smooth operation of the entire system.

[0073] like Figure 5 、 Figure 6 、 Figure 7 As shown, the filter assembly includes a conical bucket 5, which is slidably arranged in the vertical direction inside the passivation box 1. The bottom of the conical bucket 5 includes a circular tube 501, and an inverted "T"-shaped guide column 502 is fixed to the bottom of the circular tube 501;

[0074] A filter screen 503 is nested outside the guide column 502. The diameter of the filter screen 503 is larger than the bottom opening diameter of the circular tube 501. A buoyancy tank 504 is fixedly connected to the bottom of the filter screen 503.

[0075] During the downward movement of the placement tray 2, it abuts against the surface of the conical bucket 5, driving the conical bucket 5 downward. The float box 504 is moved upward by the buoyancy of the passivation liquid. The filter screen 503 is tightly fitted to the bottom surface of the circular tube 501. At the same time, the passivation liquid enters the circular tube 501 after being filtered by the filter screen 503, thereby filtering the passivation liquid. The filtered passivation liquid reacts with the casting to passivate, thereby reducing the adhesion of impurities to the casting surface.

[0076] After the passivation reaction is completed, the tray 2 is placed upward, and under the action of the float box 504, the conical bucket 5 is reset upward, so that the impurities generated by the passivation reaction are precipitated into the inside of the circular tube 501 for temporary storage, so as to reduce the impurities being stirred up by the flow of the passivation liquid, which is conducive to continuous production.

[0077] like Figure 8 As shown, the top of the filter screen 503 is fixedly connected to a limit ring 505, and the outer diameter of the limit ring 505 is the same as the bottom opening diameter of the circular tube 501;

[0078] When the filter screen 503 fits tightly against the bottom of the circular tube 501, the limiting ring 505 is embedded in the circular tube 501 to ensure the accuracy of the position of the filter screen 503, while increasing the sealing path and reducing the situation where impurities enter the conical bucket 5, so that the circular tube 501 and the filter screen 503 fit more closely.

[0079] like Figure 7 As shown, a gas spring 506 is fixedly installed at the bottom of the conical bucket 5, and the other end of the gas spring 506 is fixed to the inner bottom end of the passivation box 1;

[0080] The gas spring 506 guides the displacement of the conical bucket 5 and can float the conical bucket 5 together with the float box 504 to the level of the passivation liquid when the conical bucket 5 is reset. Under the action of the gravity of the float box 504 itself, the filter screen 503 separates from the circular tube 501. At the same time, the passivation liquid in the circular tube 501 flows downward and impacts the filter screen 503. Impurities on the surface of the filter screen 503 can fall into the passivation box 1 for precipitation, thereby circulating, ensuring that during continuous processing, impurities in the passivation liquid can be separated from the casting, accelerating processing efficiency while ensuring the passivation processing quality.

[0081] like Figure 7 As shown, the inclined surface of the conical bucket 5 is hinged with a rotating shaft 507, and the rotating shaft 507 is arranged just below the placement tray 2;

[0082] The rotating shaft 507 can cooperate with the baffle 204, and the placement plate 2 is separated from the bottom surface of the conical bucket 5 by a certain distance to avoid stirring up impurities in the conical bucket 5. The placement plate 2 can rotate smoothly, and the impact on the conical bucket 5 is reduced, ensuring the normal use of the conical bucket 5.
