Description

Technical Field

[0002] In some boiler equipment, workpieces such as grates, furnace rollers and radiation tubes generally need to be cast using heat-resistant and wear-resistant steel. Commonly used casting methods are generally sand casting, investment casting and differential pressure casting, among which sand casting is a traditional and widely used method, using sand, water, clay and other materials as a casting mold. The green sand mixture is usually compacted around the model by a machine. The better the compaction effect of the green sand mixture, the fewer pores and burrs on the surface of the cast workpiece. The Chinese patent document publication number CN117983779B discloses a casting device for the production of pump and valve castings, including a bearing structure, a sand lowering structure and a hammer pressing structure; the sand lowering structure is movably arranged above the bearing structure, and the hammer pressing structure is movably arranged on the front side of the bearing structure. The present invention autonomously pushes the material to be discharged through the sand lowering structure , hammer pressure structure for compaction and scraping, which greatly reduces manual operation and improves production efficiency; since the raw sand can fully enter the mold frame and be fully compacted, the accuracy and surface quality of the model can be ensured; the required manual operation is reduced, the labor cost is reduced, and errors due to human fatigue or carelessness can be avoided; automated operation can quickly complete the steps of loading, compacting, scraping and so on of the raw sand, shortens the production cycle and improves production efficiency, but a model needs to be placed in the mold frame, and an appropriate amount of wet sand mixture needs to be added at one time before stamping can be carried out, and it only stamps on the surface of the wet sand mixture, which can easily cause the upper layer of the wet sand mixture to be compacted, while the lower layer of the wet sand mixture has large gaps, which will cause the wet sand mixture to be heated and deformed during the casting process, resulting in a decrease in the yield of finished products.

[0015] (III) Beneficial effects The invention provides a heat-resistant and wear-resistant steel production equipment and method, which has the following beneficial effects: 1. When the pressure rod moves up and down, it drives the piston plate to move up and down inside the piston bin, and blows or sucks air to the lower part of the driving bin on both sides through the connecting pipes 2 on both sides, and then drives the connecting rod and neodymium magnet 1 on the upper end to rotate back and forth through the impeller at the lower end of the driving shaft. When the neodymium magnet 1 attracted by the neodymium magnet 2 rotates close to the neodymium magnet 2, the striking head at the other end of the striking shaft is driven away from the mold frame through the cooperation of the balls on the outer periphery of the slide plate. When the neodymium magnet 1 repelled by the neodymium magnet 2 rotates close to the neodymium magnet 2, the striking head is pushed to hit the middle of both sides of the mold frame alternately. Through the cooperation of the rotating assembly, the middle part of the outer periphery of the mold frame is struck, so that the wet sand mixture in the middle of the mold frame becomes dense due to vibration, and the pores in the middle of the wet sand mixture in the mold frame are removed, so that the middle of the wet sand mixture in the mold frame is made tighter, which improves the compaction effect, thereby avoiding the situation in which the wet sand mixture is deformed by heat during the casting process, resulting in a decrease in the yield rate.

[0016] 2. When the connecting pipe 2 blows air into the driving bin, the airflow enters the ash box through the connecting pipe 1 and the filter, and enters the cavity through the connecting groove and the air inlet groove, blowing the rotating blades and the knocking blades to rotate, so that the knocking blades continuously knock the metal strips to generate vibrations, which are transmitted to the lower end of the mold frame through the chuck and the rotor, so that the lower part of the wet sand mixture inside the mold frame becomes denser due to the vibration, and the pores in the lower part of the wet sand mixture in the mold frame are removed, so that the lower part of the wet sand mixture in the mold frame is made tighter, so that the compaction effect is better, and the finished product forming rate of the wear-resistant and heat-resistant steel is further improved.

[0017] 3. Since the upper end of the chuck has a certain slope and baffles are provided at the front and rear ends, the wet sand mixture particles that fall during the compaction process will slide to both sides due to the vibration caused by the knocking blades and the metal bars, until they slide to the upper end of the ash baffle plate at the lower part of the ash collecting trough, thereby vibrating and temporarily collecting the wet sand mixture particles at the upper end of the chuck.

[0018] 4. When the connecting pipe drives the interior of the bin to evacuate air, the rotating blade and the striking blade rotate, and the striking blade is pulled by spring one, so that the striking blade is stuck to the metal bar and no longer rotates, and thus cannot absorb air, causing the interior of the ash collecting box to be in a negative pressure state, thereby causing the ash baffle plate to open, and the wet sand mixture particles that fall to the upper end of the ash baffle plate slide into the ash collecting box for storage, thereby realizing continuous collection of the wet sand mixture particles, which is beneficial to later reuse.

[0019] 5. When the gas entering the cavity is blown toward the upper end of the ash baffle plate from the air outlet groove, the wet sand mixture particles move to the side away from the upper end of the ash baffle plate. When the ash baffle plate is opened, the wet sand mixture particles on the upper end of the ash baffle plate are more likely to fall into the ash collecting box for storage.

The molding rate of the product is improved, and because the upper end of the chuck 1019 has a certain slope and baffles are provided at the front and rear ends, the wet sand mixture particles that fall during the compaction process slide to both sides due to the vibration caused by the knocking blade 1027 knocking the metal bar 1024, until they slide to the upper end of the ash baffle 1034 at the lower part of the ash collecting trough 1032, so that the wet sand mixture particles at the upper end of the chuck 1019 are vibrated and temporarily collected, and when the gas entering the cavity 1023 is blown toward the upper end of the ash baffle 1034 from the air outlet groove 1030, the wet sand mixture particles move to the side away from the upper end of the ash baffle 1034, and when the ash baffle 1034 is opened, the wet sand mixture particles at the upper end of the ash baffle 1034 are more likely to fall into the ash collecting box 1037 for storage.

[0039] A method for producing heat-resistant and wear-resistant steel, applied to any one of the above-mentioned heat-resistant and wear-resistant steel production equipment, characterized in that it comprises the following steps: S1, adding a certain amount of green sand mixture into the mold frame 2, placing the model in the green sand mixture, and continuing to add the green sand mixture, adjusting the position of the model, and scraping off excess green sand mixture; S2, placing the mold frame 2 on the upper end of the placement plate 1017, and adjusting the direction of the mold frame 2 so that the slot at the lower end of the mold frame 2 is sleeved on the upper end of the limiting frame 1018, and starting the clamping assembly to limit the mold frame 2; S3, start the motor 103 in the compacting component, compact the green sand mixture in the mold frame 2 through the cooperation of the rotating component, the vibrating component, the knocking component and the ash storage component, and collect the green sand mixture dropped during the compaction process. After compaction, start the clamping component, remove the mold frame 2, and pour the molten heat-resistant and wear-resistant steel into the green sand mixture in the mold frame 2 after mold closing. After cooling, remove the mold and take out the cast heat-resistant and wear-resistant steel product.

[0040] Working principle: Place the mold frame 2 containing the green sand mixture and the model on the upper end of the placement plate 1017, and make the slot at the lower end of the mold frame 2 engage with the limiting frame 1018, start the electric push rod 1022, and drive the clamping plates 1019 on both sides to approach the mold frame 2 through the driving frame 1021 until the rotating wheel 1020 fits with the lower end of the mold frame 2 and stops, limit the mold frame 2, start the motor 103, drive the rotating disk 105 to rotate through the driving roller 104, and then drive the pressing rod 107 to move up and down through the connecting rod 106, and then hammer the upper end of the green sand mixture inside the mold frame 2 through the pressing plate 109. At the same time, the driving roller 104 drives the pulley 1013 to rotate through the pulley 1 1011 and the transmission belt 1012, and then through the transmission The shaft 1014 and the bevel gear 1015 drive the conical toothed disc 1016 to rotate, and finally drive the mold frame 2 to rotate through the placement disc 1017 and the upper limit frame 1018 to complete the upper compaction of the wet sand mixture at different positions in the mold frame 2. In the process, the wet sand mixture becomes less and the wet sand mixture can be appropriately added. When the pressure rod 107 moves up and down, it drives the piston plate 1010 to move up and down inside the piston chamber 108, and blows or sucks air to the lower part of the driving chamber 1040 on both sides through the connecting pipe 1051 on both sides, and then drives the impeller 1042 at the lower end of the driving shaft 1041 to drive the connecting rod 1043 and the neodymium magnet 1 1044 at the upper end to reciprocate. When the neodymium magnet 1 1044 attracted to the neodymium magnet 1050 rotates close to the neodymium magnet 1050, the impeller 1042 at the lower end of the driving shaft 1041 drives the connecting rod 1043 and the neodymium magnet 1 1044 to rotate back and forth. When the magnet 1050 is rotated, the ball 1049 on the periphery of the slide plate 1048 cooperates to drive the knocking head 1047 at the other end of the knocking shaft 1046 away from the mold frame 2. When the neodymium magnet 1044 that repels the neodymium magnet 1050 rotates and approaches the neodymium magnet 1050, the knocking head 1047 is pushed to alternately hit the middle of both sides of the mold frame 2. Through the cooperation of the rotating component, the knocking of the middle of the periphery of the mold frame 2 is completed, so that the wet sand mixture in the middle of the mold frame 2 becomes denser due to vibration, and the pores in the middle of the wet sand mixture in the mold frame 2 are removed, so that the middle of the wet sand mixture in the mold frame 2 is made denser, the compaction effect is improved, and the situation that the wet sand mixture is deformed by heat during the casting process and the yield rate is reduced is avoided. When the second pipe 1051 blows air into the driving bin 1040, the airflow enters the interior of the ash box 1037 through the connecting pipe 1039 and the filter 1038, and enters the interior of the cavity 1023 through the connecting groove 1031 and the air inlet groove 1029, blowing the rotating blade 1026 and the knocking blade 1027 to rotate, so that the knocking blade 1027 continuously knocks the metal strip 1024 to generate vibration, and the vibration is transmitted to the lower end of the mold frame 2 through the chuck 1019 and the rotating wheel 1020, so that the lower part of the green sand mixture inside the mold frame 2 becomes denser due to the vibration, and the pores in the lower part of the green sand mixture in the mold frame 2 are removed, so that the lower part of the green sand mixture in the mold frame 2 is made tighter, so that the compaction effect is better, and the finished product forming rate of the wear-resistant and heat-resistant steel is further improved.Since the upper end of the chuck 1019 has a certain slope and baffles are provided at the front and rear ends, the wet sand mixture particles that fall during the compaction process slide to both sides due to the vibration caused by the knocking blade 1027 knocking the metal strip 1024, until they slide to the upper end of the ash baffle 1034 at the lower part of the ash collecting trough 1032, so that the wet sand mixture particles at the upper end of the chuck 1019 are vibrated away and temporarily collected. When the connecting pipe 1051 draws air into the driving bin 1040, the rotating blade 1026 and the knocking blade 1027 rotate, and the knocking blade 1027 is pulled by the spring 1028, so that the knocking blade 1027 is stuck to the metal strip 1024 and no longer rotates. , and thus air cannot be sucked in, so that the inside of the ash box 1037 is in a negative pressure state, and then the ash baffle 1034 is opened, and the wet sand mixture particles that fall to the upper end of the ash baffle 1034 slide into the ash box 1037 for storage, realizing the continuous collection of wet sand mixture particles, which is beneficial to the later reuse, and when the gas entering the cavity 1023 is blown to the upper end of the ash baffle 1034 from the air outlet groove 1030, the wet sand mixture particles move to the side away from the upper end of the ash baffle 1034, and when the ash baffle 1034 is opened, the wet sand mixture particles on the upper end of the ash baffle 1034 are more likely to fall into the ash box 1037 for storage. ,
