Description

Technical Field

[0001] This invention belongs to the field of metal casting processing and pouring technology, and specifically relates to a pouring device and method for improving porosity defects in DISA vertical line castings. Background Technology

[0002] In the field of casting and precision casting, the purity of molten metal is one of the key factors that determines the final quality of castings. If non-metallic slags such as oxides, sulfides, and furnace lining debris are not effectively removed from the molten metal, they can easily lead to defects such as porosity, slag inclusions, and cold shuts in the castings, which can seriously reduce mechanical properties and yield.

[0003] According to the prior art announcement number CN119328116A, a casting device and casting method for large castings are described. Although the prior art can remove large and small waste slags in the casting cylinder before casting, it cannot filter non-metallic slags in the molten metal during casting, which increases the risk of defects such as porosity, slag inclusions, and cold shuts in the castings, and is difficult to meet the casting requirements of castings with high cleanliness requirements.

[0004] Further research revealed that the existing technology, CN223056679U, is a casting slag-blocking device. This technology intercepts slag in the molten metal using a slag-blocking ring and a diversion bag, but it does not clean the non-metallic slag filtered in the diversion bag. This results in the continuous accumulation of filtered slag inside and on the surface of the diversion bag, reducing diversion and filtration efficiency. Furthermore, it cannot achieve online removal of the filtered slag. Consequently, the filtration effect of this slag-blocking device gradually diminishes in long-term continuous casting scenarios, making it difficult to meet the mass production requirements of castings with high cleanliness and stability. Summary of the Invention

[0005] 1) The purpose of this invention is to overcome the shortcomings of the prior art and provide a casting device and method to improve the porosity defects of DISA vertical line castings. The slag filtering mechanism filters non-metallic slag in the molten metal while realizing online replacement of the filter plate without interrupting the casting process, which significantly improves equipment utilization and production efficiency. It can also unclog blocked filter holes, extend the service life of the filter plate, and reduce the frequency of filter plate maintenance. The cleaning mechanism can efficiently remove stubborn slag from the side wall and bottom of the pouring cup, ensuring the purity and stability of continuous production.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A method for improving the porosity defect in DISA vertical line castings is as follows:

[0008] 1) Conveying and positioning: The casting molds are conveyed forward sequentially by a conveyor belt with a speed of 0.05-0.1m / s, so that the casting molds arrive at the bottom of the filter cake mechanism in sequence, ready for casting. The dwell time of the casting molds is 15-20s.

[0009] 2) Gear motor I drives lead screw I to rotate, causing the support rod to move on the fixed frame I at a speed of 50-80 mm / s, thereby achieving horizontal positioning of the casting cylinder with a horizontal stroke of 0-600 mm; gear motor II drives lead screw II to rotate, causing sliding frame I to move up and down along the support rod at a speed of 40-60 mm / s with a vertical stroke of 0-400 mm, thereby completing the vertical adjustment of the casting cylinder and moving the casting cylinder above the filter cake mechanism;

[0010] 3) Motor I drives lead screw III to rotate, and the connecting plate moves horizontally along sliding rod III at a speed of 40-70 mm / s, with a horizontal stroke of 0-500 mm, so that the sprue cup is moved directly above the sprue of the casting mold, with a centering deviation of ≤1.5 mm; Motor II drives rotating shaft II to rotate at a speed of 150-250 rpm, and rotating shaft I drives swing rod I to swing, so that lifting rod slides up and down along sliding groove I in the fixed shell, with a sliding stroke of 0-100 mm, so that lifting rod drives sprue cup down to the sprue position of the casting mold, with a descent time of ≤3 s;

[0011] 4) Pouring and Filtration: The servo motor drives the mounting bracket I to adjust the angle, with an angular velocity of 5-8° / s. The molten metal is poured into the pouring cup at a flow rate of 0.5-2.5 kg / s. The heating block inside the pouring cup keeps the temperature 20-30°C higher than the pouring temperature. The filter plate with a hole diameter of 0.5-1.5 mm at the bottom of the pouring cup filters the non-metallic impurities in the molten metal. The purified molten metal flows into the pouring mold below.

[0012] 5) Filter plate replacement and cleaning: After a set of casting molds is completed, a set of hydraulic cylinders II drives the sliding frame II to be pulled out from the bottom of the pouring cup along the slide rail through the hydraulic synchronization valve. Another set of hydraulic cylinders II simultaneously drives another set of sliding frames II to slide into the bottom of the pouring cup's discharge port to continue filtering the next set of casting molds. Hydraulic cylinder III pushes the cleaning frame down along the sliding rod IV. The descent stroke is 0-80mm and the descent speed is 30-50mm / s. The ejector pin, with a diameter 0.1-0.2mm smaller than the filter plate's hole diameter, is precisely inserted into the filter hole of the filter plate to be cleaned, pushing out the blockage residue. The cleaning time for a single filter plate is 4-6 seconds.

[0013] 6) Sprue Cup Cleaning: Motor I drives screw III to rotate, causing the sprue cup to move at a speed of 40-70 mm / s to the top of the cleaning mechanism. Hydraulic cylinder I drives rack and pinion to rotate, causing the clamp and sprue cup to flip over. The sprue cup is lowered by the lifting rod and placed upside down on the top of the cleaning mechanism. Motor IV drives screw IV to rotate, causing the connecting rod to push swing rod II to swing. Scraper II adheres to the side wall of the sprue cup and moves circumferentially along the cup wall at a speed of 20-35 rpm to scrape off the residue on the side wall. Hydraulic cylinder IV drives scraper I to extend from the top of rotating shaft III, adhere to the side wall of the leakage port, and scrape off the residual filter residue. The residue after cleaning falls into the collection hood for unified recycling.

[0023] The advantages of this invention compared to existing technologies are as follows:

[0024] 2) The molten metal enters the pouring cup, and the heating block continues to heat it to maintain the temperature of the molten metal and prevent it from solidifying too early. The filter plate filters and intercepts non-metallic impurities in the molten metal, and the purified molten metal flows into the pouring mold below. The filter plate filters out the filter residue in the molten metal, thereby significantly improving the purity of the molten metal, reducing defects such as porosity inside the casting, and improving the mechanical properties and surface quality of the casting.

The hydraulic cylinder III pushes the cleaning frame down along the sliding rod IV, and the ejector pin is inserted into the filter hole of the filter plate that needs to be cleaned to push out the blocked residue. By quickly switching between the two sets of sliding frames, the filter plate can be replaced online without interrupting the casting process, which significantly improves the equipment utilization and production efficiency. The hydraulic cylinder III drives the ejector pin to accurately unclog the blocked filter hole, automatically clean the residue, restore the filtration capacity, extend the service life of the filter plate, and reduce the frequency of filter plate maintenance.

[0026] 4) Motor IV drives lead screw IV to rotate, and connecting rod pushes swing rod II to swing, so that scraper II at the top of swing rod II fits against the side wall of the pouring cup. Scraper II moves circumferentially along the pouring cup wall to scrape off the residue attached to the side wall. Hydraulic cylinder IV drives scraper I to extend from the top of rotating shaft III and fit against the side wall of the discharge port at the bottom of the pouring cup to scrape off the filter residue around the discharge port. This can efficiently remove stubborn filter residue from the side wall and bottom of the pouring cup, prevent filter residue from mixing into subsequent molten metal, and ensure the purity and stability of continuous production.

[0046] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-18 The technical solution of the present invention will be further described in detail below.

[0047] A method for improving the porosity defect in DISA vertical line castings is as follows:

[0048] 1) Conveying and positioning: The casting molds are conveyed forward sequentially by a conveyor belt with a speed of 0.05-0.1m / s, so that the casting molds arrive at the bottom of the filter cake mechanism in sequence, ready for casting. The dwell time of the casting molds is 15-20s.

[0049] 2) Gear motor I drives lead screw I to rotate, causing the support rod to move on the fixed frame I at a speed of 50-80 mm / s, thereby achieving horizontal positioning of the casting cylinder with a horizontal stroke of 0-600 mm; gear motor II drives lead screw II to rotate, causing sliding frame I to move up and down along the support rod at a speed of 40-60 mm / s with a vertical stroke of 0-400 mm, thereby completing the vertical adjustment of the casting cylinder and moving the casting cylinder above the filter cake mechanism;

[0050] 3) Motor I drives lead screw III to rotate, and the connecting plate moves horizontally along sliding rod III at a speed of 40-70 mm / s, with a horizontal stroke of 0-500 mm, so that the sprue cup is moved directly above the sprue of the casting mold, with a centering deviation of ≤1.5 mm; Motor II drives rotating shaft II to rotate at a speed of 150-250 rpm, and rotating shaft I drives swing rod I to swing, so that lifting rod slides up and down along sliding groove I in the fixed shell, with a sliding stroke of 0-100 mm, so that lifting rod drives sprue cup down to the sprue position of the casting mold, with a descent time of ≤3 s;

[0051] 4) Pouring and Filtration: The servo motor drives the mounting bracket I to adjust the angle, with an angular velocity of 5-8° / s. The molten metal is poured into the pouring cup at a flow rate of 0.5-2.5 kg / s. The heating block inside the pouring cup keeps the temperature 20-30°C higher than the pouring temperature. The filter plate with a hole diameter of 0.5-1.5 mm at the bottom of the pouring cup filters the non-metallic impurities in the molten metal. The purified molten metal flows into the pouring mold below.

[0052] 5) Filter plate replacement and cleaning: After a set of casting molds is completed, a set of hydraulic cylinders II drives the sliding frame II to be pulled out from the bottom of the pouring cup along the slide rail through the hydraulic synchronization valve. Another set of hydraulic cylinders II simultaneously drives another set of sliding frames II to slide into the bottom of the pouring cup's discharge port to continue filtering the next set of casting molds. Hydraulic cylinder III pushes the cleaning frame down along the sliding rod IV. The descent stroke is 0-80mm and the descent speed is 30-50mm / s. The ejector pin, with a diameter 0.1-0.2mm smaller than the filter plate's hole diameter, is precisely inserted into the filter hole of the filter plate to be cleaned, pushing out the blockage residue. The cleaning time for a single filter plate is 4-6 seconds.

[0053] 6) Sprue Cup Cleaning: Motor I drives screw III to rotate, causing the sprue cup to move at a speed of 40-70 mm / s to the top of the cleaning mechanism. Hydraulic cylinder I drives rack and pinion to rotate, causing the clamp and sprue cup to flip over. The sprue cup is lowered by the lifting rod and placed upside down on the top of the cleaning mechanism. Motor IV drives screw IV to rotate, causing the connecting rod to push swing rod II to swing. Scraper II adheres to the side wall of the sprue cup and moves circumferentially along the cup wall at a speed of 20-35 rpm to scrape off the residue on the side wall. Hydraulic cylinder IV drives scraper I to extend from the top of rotating shaft III, adhere to the side wall of the leakage port, and scrape off the residual filter residue. The residue after cleaning falls into the collection hood for unified recycling.

The control program described above is not within the scope of protection of this invention.

[0056] The conveyor belt 102 transports several sets of casting molds 103 forward in sequence. When the mold reaches directly below the slag filter mechanism 3, the casting mechanism 2 injects molten metal into the casting mold 103. Before the molten metal falls into the casting mold 103, the slag filter mechanism 3 filters the injected molten metal, effectively intercepting slag and impurities. The purified molten metal flows into the casting mold 103. The cleaning mechanism 4 cleans the slag filter components in the slag filter mechanism 3 periodically.

[0063] The pouring cup 317 has several sets of heating blocks 318 inside its cup wall. The heating blocks 318 contain high-resistance electric heating alloy wires. When energized, the current passes through the resistance wires to generate Joule heat. The heat is transferred to the outer shell of the heating block through the thermally conductive insulating medium, and then the cup wall and the internal molten metal of the pouring cup 317 are heated and kept warm through thermal radiation and thermal conduction.

[0064] As described above: Motor I 35 drives the lead screw III 34 to rotate, which in turn drives the connecting plate 33 to move horizontally along the sliding rod III 32, so that the pouring cup 317 moves to the position directly above the pouring port of the pouring mold 103. Motor II 310 drives the rotating shaft II 311 to rotate, which in turn drives the worm gear to rotate. The worm gear drives the worm wheels on the two sets of rotating shafts I 39 to rotate synchronously. The rotating shaft I 39 drives the swing rod I 38 to swing. The swing rod I 38 pushes the lifting rod 312 to slide up and down along the sliding groove I 3701 in the fixed shell 37. The lifting rod 312 drives the pouring cup 317 to descend to the pouring port position of the pouring mold 103.

[0065] During pouring, the molten metal enters the pouring cup 317, and the heating block 318 continuously heats it to maintain the temperature of the molten metal and prevent it from solidifying too early. The molten metal then flows through the filter plate 321 in the mounting bracket Ⅲ 319 at the bottom of the pouring cup 317. The filter plate 321 filters and intercepts non-metallic impurities in the molten metal, and the purified molten metal flows into the pouring mold 103 below.

[0066] When a set of casting molds 103 finishes casting and the filter plate 321 is replaced, a set of hydraulic cylinders II 323 drives the sliding frame II 320 to be pulled out from the middle of the mounting frame III 319 along the slide rail 322 through the hydraulic synchronization valve. Another set of hydraulic cylinders II 323 synchronously drives another set of sliding frames II 320 to slide into the middle of the mounting frame III 319 to filter the molten metal. The hydraulic cylinder III 326 pushes the cleaning frame 327 down along the sliding rod IV 325. The ejector pin 328 is precisely inserted into the filter hole of the filter plate 321 that needs to be cleaned, and pushes out the blocked residue to clean it.

[0067] In the description of this invention, the hydraulic power system used in hydraulic structures such as hydraulic cylinder I 316, hydraulic cylinder II 323, and hydraulic cylinder III 326 is a conventional hydraulic power system in the prior art. The hydraulic power system takes a hydraulic pump as its core, converting the mechanical energy of the prime mover into the pressure energy of the hydraulic oil. After the high-pressure oil is adjusted in direction, pressure, and flow by the hydraulic control valve group, it drives several sets of actuators to output motion to complete the work. When several sets of actuators need to operate synchronously, the high-pressure oil is adjusted in direction, pressure, and flow by the hydraulic control valve group and the hydraulic synchronization valve group, driving several sets of actuators to output motion synchronously to complete the work.
