Description

Technical Field

[0001] This invention relates to the field of heat treatment technology for alloy cast iron products, and more specifically to a tilting material frame structure for heat treatment of alloy cast iron products. Background Technology

[0002] Alloy cast iron products need to undergo heat treatment to achieve the corresponding properties, such as quenching and tempering. Heat treatment requires heating the alloy cast iron products to a suitable temperature. Therefore, the alloy cast iron products are loaded into a material frame and then sent to a heating furnace for heating. After heating, the alloy cast iron products are transported to the cooling mechanism through the material frame. Since the temperature of the alloy cast iron products is very high at this time, they are generally not picked up directly. Instead, the material frame is flipped so that the alloy cast iron products can be poured out directly for subsequent cooling treatment.

[0003] The existing tilting material frame structure for heat treatment of alloy cast iron products is shown in the attached figure. Figure 10 As shown, the support base of the material frame is fixed to the top surface of the structural base, and the material frame is directly driven by a hydraulic cylinder to flip the material frame. During the flipping process, the horizontal position of the material frame cannot be adjusted. A guide plate is required to pour the alloy cast iron product into the receiving frame. After the material frame is flipped, the alloy cast iron product is easy to remain in the material frame, which requires manual secondary cleaning. Summary of the Invention

[0004] To overcome the aforementioned technical problems, the present invention aims to provide a flip-type material frame structure for heat treatment of alloy cast iron products. Through a supporting base, a receiving frame for receiving alloy cast iron products is set on the flipping side of the material frame body. The supporting plate adjusts the horizontal position of the material frame body, bringing it closer to the receiving frame to prevent the alloy cast iron products from slipping out. This improves the accuracy of unloading when the material frame body flips, ensuring that the material frame body can accurately pour the alloy cast iron products into the receiving frame. Through a guide block, when the guide block is in a vertical state, the rectangular sliders on both sides of the material frame body slide towards one end of the guide groove, lowering the center of gravity of the material frame body and improving its stability. When unloading is required, the material frame body is flipped between 100° and 120°. At this time, under its own weight, the material frame body slides towards the other end of the guide groove via the rectangular sliders, generating a vibration effect when the material frame body stops, ensuring that the alloy cast iron products inside the material frame body can be completely discharged.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A tilting feeder structure for heat treatment of alloy cast iron products, including:

[0007] The structural base includes a movable base and a support base. The top surface of the support base is provided with limiting slide rails at both ends, and the limiting slide rails are provided with fixing screws inside. The top surface of the support base is provided with an isolation plate in the middle.

[0008] The support base consists of two sets, each set on the top surface of a set of limiting slide rails. Each support base includes a support plate, a track slider is fixedly connected to the bottom surface of the support plate, and a drive gear ring is installed on the top of the support plate. The track slider and the limiting slide rails are mutually engaged.

[0009] A flip-up material frame includes a material frame body, rectangular sliders are fixedly connected to the center positions of both sides of the material frame body, and a guide block is nested on the side of the rectangular slider away from the material frame body. The guide block is threadedly connected to the drive gear ring.

[0010] A flipping mechanism is provided on the side of one of the sets of support seats. The flipping mechanism is used to drive the flipping material frame to flip and unload the material.

[0011] As a further aspect of the present invention: movable wheels are installed at the four corners of the bottom surface of the movable base, and the movable wheels are concave wheels.

[0012] As a further aspect of the present invention: a ball nut is rotatably connected to the inner middle position of the track slider, a transmission toothed belt is nested on the side of the ball nut, a first helical gear is engaged at the end of the transmission toothed belt away from the ball nut, a second helical gear is engaged on the back of the first helical gear, and the top surface of the second helical gear is engaged with the bottom surface of the drive gear ring.

[0013] As a further aspect of the present invention: a hydraulic cylinder is fixedly connected to the middle position of the inner side of the support plate, and a limit push block is connected to the top of the hydraulic cylinder by a hydraulic rod bolt. Limit plates are fixedly connected to the two sides of the inner side of the support plate near the limit push block.

[0014] As a further aspect of the present invention: a guide groove that fits into the rectangular slider is provided on one side of the guide block near the rectangular slider, and a rotating shaft is fixedly connected to the middle position of the other side of the guide block, and the rotating shaft is threadedly connected to the drive gear ring.

[0015] As a further aspect of the present invention: a limiting groove is provided at the bottom middle position of the guide groove, and the limiting groove and the limiting push block are mutually matched.

[0016] As a further aspect of the present invention: the flipping mechanism includes a housing, the housing being bolted to the outer side of a support plate, and a support block being provided at the bottom of the housing, the support block being bolted to the outer side of the support plate.

[0017] As a further aspect of the present invention: a ring of toothed grooves is formed on the inner wall of the outer shell, and a plurality of planetary gears are provided on the inner side of the outer shell to mesh with the toothed grooves. A gear carrier is provided on the side of the plurality of planetary gears, and the center position of the gear carrier on the side away from the planetary gears is fixedly connected to the center position of the rotating shaft.

[0018] As a further aspect of the present invention: a sun shaft is meshed on the inner side of several of the planetary gears, and a drive groove is provided on the side of the housing near the sun shaft.

[0019] The beneficial effects of this invention are:

[0020] 1. In this invention, the support plate can be adjusted in position by the mutual engagement of the track slider and the limiting slide rail through the support base. When the main body of the material frame is flipped, a receiving frame for receiving alloy cast iron products is set on the flipped side of the main body of the material frame. The support plate will adjust the horizontal position of the main body of the material frame so that the main body of the material frame is closer to the receiving frame, preventing the alloy cast iron products from sliding out. This improves the accuracy of unloading when the main body of the material frame is flipped, and ensures that the main body of the material frame can accurately pour the alloy cast iron products into the receiving frame.

[0021] 2. In this invention, when the flipping mechanism drives the flipping material frame, it will drive the drive gear ring to rotate. The rotating drive gear ring will drive the first helical gear through the second helical gear. The first helical gear will drive the ball nut through the transmission tooth belt. The ball nut is nested on the outside of the fixed screw. When the ball nut rotates, since the fixed screw is fixed in the limit slide rail, the ball nut will move along the axial direction of the fixed screw, which realizes the movement of the support plate. This ensures that when the flipping material frame is flipped, the support plate will automatically drive the flipping material frame to move closer to the receiving frame.

[0022] 3. In this invention, by setting a guide block, when the guide block is in a vertical state, the rectangular sliders on both sides of the material frame body will slide to one end of the guide groove, which lowers the center of gravity of the material frame body and improves the stability of the material frame body. When unloading is required, the material frame body will be flipped between 100° and 120°. At this time, the material frame body will slide to the other end of the guide groove through the rectangular sliders under its own gravity, and will generate a vibration effect when the material frame body stops, ensuring that the alloy cast iron products in the material frame body can be completely discharged.

[0023] 4. In this invention, by setting a limiting push block, the hydraulic cylinder is opened, and the hydraulic cylinder pushes the limiting push block through the hydraulic rod, so that the limiting push block is stuck in the limiting groove, restricting the position of the guide block and stabilizing the position of the guide block, thereby stabilizing the position of the material frame body and ensuring that the material frame body will not shake during the transportation of alloy cast iron products.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-9 As shown, a flip-type material frame structure for heat treatment of alloy cast iron products is provided. The flip-type material frame structure includes a structural base 1, which includes a movable base 11 and a support base 13. The top surface of the support base 13 is provided with limiting slide rails 14 at both ends. The limiting slide rails 14 are provided with fixing screws 16 inside. The top surface of the support base 13 is provided with an isolation plate 15 in the middle. The bottom surface of the movable base 11 is provided with movable wheels 12 at the four corners. The movable wheels 12 are concave wheels.

[0038] The isolation plate 15 is integrally molded with heat insulation material, which can isolate the heat at the top of the support base 13, reduce the working temperature of the movable base 11 and the movable wheels 12 on the movable base 11, and increase the service life of the movable base 11 and the movable wheels 12.

[0039] like Figures 3-7 As shown, a support seat 2 is provided on the top surface of both sets of limiting slide rails 14. The support seat 2 includes a support plate 21. A track slider 22 is fixedly connected to the bottom surface of the support plate 21. A drive gear ring 23 is installed on the top of the support plate 21. The track slider 22 and the limiting slide rail 14 are fitted together. A flipping material frame 3 is provided on the inner side of the two sets of support seats 2. The flipping material frame 3 includes a material frame body 31. A rectangular slider 32 is fixedly connected to the center position of both sides of the material frame body 31. A guide block 33 is nested on the side of the rectangular slider 32 away from the material frame body 31. The guide block 33 is threadedly connected to the drive gear ring 23.

[0040] The support plate 21 can be adjusted in position by the mutual engagement of the track slider 22 and the limiting slide rail 14. When the material frame body 31 is flipped, a receiving frame for receiving alloy cast iron products will be set on the flipped side of the material frame body 31. The support plate 21 will adjust the horizontal position of the material frame body 31 so that the material frame body 31 is closer to the receiving frame, preventing the alloy cast iron products from sliding out and improving the accuracy of unloading when the material frame body 31 is flipped.

[0041] The flipping mechanism 4 is located on the side of one of the support seats 2. The flipping mechanism 4 is used to drive the flipping material frame 3 to flip and unload the material.

[0042] In actual operation, the rotating material frame 3 is transported to the receiving frame position by moving the base 11, and then the rotating mechanism 4 is opened. The rotating mechanism 4 can drive the rotating material frame 3 to rotate and unload the material. When the rotating material frame 3 rotates and unloads the material, the support plate 21 will adjust the horizontal position of the material frame body 31 so that the material frame body 31 is closer to the receiving frame, ensuring that the material frame body 31 can accurately pour the alloy cast iron product into the receiving frame.

[0043] like Figures 1-4As shown, a ball nut 221 is rotatably connected to the middle position of the inner side of the track slider 22. A transmission toothed belt 222 is nested on the side of the ball nut 221. A first helical gear 223 is engaged at the end of the transmission toothed belt 222 away from the ball nut 221. A second helical gear 224 is engaged on the back of the first helical gear 223. The top surface of the second helical gear 224 is engaged with the bottom surface of the drive gear ring 23.

[0044] When the flipping mechanism 4 drives the flipping material frame 3, it will drive the drive gear ring 23 to rotate. The rotating drive gear ring 23 will drive the first helical gear 223 through the second helical gear 224. The first helical gear 223 will drive the ball nut 221 through the transmission belt 222. The ball nut 221 is nested on the outside of the fixed screw 16. When the ball nut 221 rotates, since the fixed screw 16 is fixed in the limit slide rail 14, the ball nut 221 will move along the axial direction of the fixed screw 16, which realizes the movement of the support plate 21. This ensures that when the flipping material frame 3 is flipped, the support plate 21 will automatically drive the flipping material frame 3 to move closer to the receiving frame.

[0045] like Figure 3 As shown, a hydraulic cylinder 24 is fixedly connected to the middle position of the inner side of the support plate 21. The top of the hydraulic cylinder 24 is connected to the limit push block 25 through a hydraulic rod bolt. Limit plates 26 are fixedly connected to the inner side of the support plate 21 near the two sides of the limit push block 25. The limit plates 26 will support the two sides of the limit push block 25, fix the horizontal position of the limit push block 25, and make the vertical movement of the limit push block 25 more stable.

[0046] like Figure 5 , Figure 6 and Figure 7 As shown, the guide block 33 has a guide groove 331 that fits into the rectangular slider 32 on one side. A rotating shaft 333 is fixedly connected to the middle position of the other side of the guide block 33. The rotating shaft 333 is threadedly connected to the drive gear ring 23.

[0047] When the guide block 33 is in a vertical position, the rectangular sliders 32 on both sides of the material frame body 31 will slide to one end of the guide groove 331, lowering the center of gravity of the material frame body 31 and improving the stability of the material frame body 31. When unloading is required, the material frame body 31 will be flipped between 100° and 120°. At this time, the material frame body 31 will slide to the other end of the guide groove 331 under its own gravity through the rectangular sliders 32, and generate a vibration effect when the material frame body 31 stops, ensuring that the alloy cast iron products in the material frame body 31 can be completely discharged.

[0048] like Figure 3 and Figure 6As shown, a limiting groove 332 is provided at the bottom center of the guide groove 331. The limiting groove 332 and the limiting push block 25 fit together. When the hydraulic cylinder 24 is opened, the hydraulic cylinder 24 will push the limiting push block 25 through the hydraulic rod, so that the limiting push block 25 is stuck in the limiting groove 332, restricting the position of the guide block 33 and stabilizing the position of the guide block 33. This stabilizes the position of the material frame body 31 and ensures that the material frame body 31 will not shake during the transportation of alloy cast iron products.

[0049] like Figure 8 and Figure 9 As shown, the flipping mechanism 4 includes a housing 41, which is bolted to the outer side of the support plate 21. A support block 42 is provided at the bottom of the housing 41, and the support block 42 is bolted to the outer side of the support plate 21. A ring of toothed grooves is formed on the inner wall of the housing 41. Several planetary gears 43 mesh with the toothed grooves on the inner side of the housing 41. A gear carrier 44 is provided on the side of the planetary gears 43. The center of the gear carrier 44 on the side away from the planetary gears 43 is fixedly connected to the center of the rotating shaft 333. A sun shaft meshes with the inner side of the planetary gears 43. A drive groove 411 is provided on the side of the housing 41 near the sun shaft. Because the material frame body 31 is heavy when carrying alloy cast iron products, the flipping mechanism... When the rotating mechanism 4 needs to rotate the material frame body 31, a hydraulic push rod structure is set near the drive groove 411. The bottom surface of the push rod has a toothed groove, which cooperates with the sun shaft. When the material frame body 31 needs to be rotated, the hydraulic push rod structure can be opened and the push rod can be pushed hydraulically. The push rod will mesh with the sun shaft and drive the sun shaft to rotate. The rotating sun shaft will drive the planetary gear 43 to rotate. The rotating planetary gear 43 will simultaneously drive the gear carrier 44 to rotate. Since the center position of the side of the gear carrier 44 away from the planetary gear 43 is fixedly connected to the center position of the rotating shaft 333, the rotation of the gear carrier 44 will also drive the rotating shaft 333 to rotate. The rotating shaft 333 will then rotate the material frame body 31.

[0050] Working principle of the invention:

[0051] First, the material frame body 31 is transported to the receiving frame position via the structural base 1. The hydraulic push rod structure can then be opened, and the push rod is hydraulically pushed. The push rod meshes with the sun shaft, causing it to rotate. The rotating sun shaft drives the planetary gear 43 to rotate, which in turn drives the gear carrier 44 to rotate. Since the center of the gear carrier 44 on the side furthest from the planetary gear 43 is fixedly connected to the center of the rotating shaft 333, the rotation of the gear carrier 44 also drives the rotating shaft 333 to rotate. The rotating shaft 333 causes the material frame body 31 to flip and also drives the drive gear ring 23 to rotate. The rotating drive gear ring 23 drives the first helical gear 223 via the second helical gear 224. The first helical gear 223... The transmission belt 222 drives the ball nut 221, which is nested on the outside of the fixed screw 16. When the ball nut 221 rotates, since the fixed screw 16 is fixed in the limit slide rail 14, the ball nut 221 will move along the axial direction of the fixed screw 16, which realizes the movement of the support plate 21. When the flipping material frame 3 is flipped, the support plate 21 will automatically drive the flipping material frame 3 to move closer to the receiving frame, and the rotating shaft 333 will flip the material frame body 31 between 100° and 120°. At this time, under the action of its own gravity, the material frame body 31 will slide to the other end of the guide groove 331 through the rectangular slider 32, and generate a vibration effect when the material frame body 31 stops, ensuring that the alloy cast iron products in the material frame body 31 can be completely discharged.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
