Description

Technical Field

[0001] The present invention belongs to the technical field of metal rolling, and specifically relates to a hot rolling device and production method for nickel-based targets with adjustable rolling force. Background Art

[0002] Nickel-based alloys refer to a class of alloys with relatively high strength and certain comprehensive properties such as antioxidant and corrosion resistance at high temperatures. According to their main properties, they are further subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, and nickel-based shape memory alloys, etc. Superalloys are divided into: iron-based superalloys, nickel-based superalloys, and cobalt-based superalloys according to the different matrices. Among them, nickel-based superalloys are simply referred to as nickel-based alloys.

[0003] Hot rolling is relative to cold rolling. Cold rolling is carried out below the recrystallization temperature, while hot rolling is carried out above the recrystallization temperature. Simply put, a steel billet is heated and then rolled through several passes, trimmed, and straightened into a steel plate, which is called hot rolling. It can significantly reduce energy consumption and costs. During hot rolling, the plasticity of the metal is high and the deformation resistance is low, greatly reducing the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys, that is, break the coarse grains in the as-cast state, significantly heal cracks, reduce or eliminate casting defects, transform the as-cast structure into a deformed structure, and improve the processing performance of the alloy.

[0004] The rolling force adjustment of traditional hot rolling equipment often achieves the goal by adjusting the distance between two rolling rolls. When the distance between the upper and lower rolling rolls is different, the rolling force will be different, and the thickness of the rolled material will also be different. However, the rolling force adjustment of the equipment and the conveying of the material to be rolled often require different power sources to drive, resulting in poor energy efficiency of the equipment. Summary of the Invention

[0005] To solve the problem proposed in the above background art that the rolling force adjustment and the conveying of the material to be rolled often require different power sources to drive, the present invention provides a hot rolling device for nickel-based targets with adjustable rolling force.

[0006] To achieve the above object, the present invention provides the following technical solution: A hot rolling device for nickel-based targets with adjustable rolling force, including a rolling table, on the upper surface of which two symmetrically distributed bearing plates are vertically fixed. A first rolling roll is rotatably connected between the two bearing plates. Two rectangular sliders are slidably connected to both of the two bearing plates. A second rolling roll is rotatably connected between the two rectangular sliders. Above the rolling table, there is an adjustment mechanism for adjusting the rolling force between the first rolling roll and the second rolling roll, and a conveying mechanism for conveying the material to be rolled.

[0007] Preferably, the adjusting mechanism includes two support rods fixed symmetrically on the upper surface of the rolling table. A pneumatic box is fixedly connected between the two support rods.

[0008] Preferably, two bent pipes which are symmetrically distributed and communicated with the inside of the pneumatic box are fixedly connected to the surface of the pneumatic box. The free ends of the bent pipes extend below the rolling table and are fixedly connected with a rectangular box communicated with the bent pipes. The upper surface of the rectangular box is an open structure. An air pipe communicated with the inside of the bent pipe is fixedly connected to the bent pipe. A first air valve is installed on the bent pipe, and a second air valve is installed on the air pipe.

[0009] Preferably, two symmetrically distributed sliding rods are slidably connected to the upper surface of the rolling table. Vertical plates are fixedly connected to the upper ends of the two sliding rods. A disc is rotatably connected to the surface of the vertical plate. Two symmetrically distributed limiting blocks are fixedly connected to the surface of the disc. A long rod is slidably connected between the two limiting blocks. One end of the long rod is integrally fixed with a rectangular plate adapted to the rectangular box.

[0010] Preferably, a vertical groove is formed on the surface of the vertical plate. A first cylindrical rod is vertically fixed to the upper end of the long rod. The free end of the first cylindrical rod is fixedly connected with a second cylindrical rod slidably adapted to the vertical groove. One end of the second cylindrical rod far away from the first cylindrical rod is fixedly connected with a circular plate. A strip-shaped frame is rotatably connected to the surface of the vertical plate. The first cylindrical rod is slidably adapted to the strip-shaped frame.

[0011] Preferably, the conveying mechanism includes a vertical rod vertically fixed on the upper surface of the rolling table. A platform is fixedly connected to the upper end of the vertical rod. A horizontal groove perpendicular to the vertical groove and an arc groove communicated with the vertical groove and the horizontal groove are formed on the vertical plate. The center positions of the arc groove and the disc are at the same point. The second cylindrical rod is slidably adapted to both the arc groove and the horizontal groove.

[0012] Preferably, a dispensing mechanism is arranged above the rolling table. The dispensing mechanism includes an L-shaped plate vertically fixed on the upper surface of the rolling table. Two coaxially fixed threaded rods are rotatably connected between the two L-shaped plates, and the thread directions on the surfaces of the two threaded rods are opposite. Internal threaded sleeves fixedly connected with the two vertical plates penetrate through the two vertical plates respectively. The two internal threaded sleeves are respectively sleeved on the two threaded rods and are in threaded connection with the threaded rods.

[0013] Preferably, gears coaxially fixed with the threaded rods are rotatably connected to the two L-shaped plates respectively. An activity groove is formed on the surface of the long rod. First magnetic attraction blocks are arranged inside both ends of the activity groove. A magnetic force rod is slidably connected in the activity groove. One end of the magnetic force rod is fixedly connected with an arc-shaped tooth plate.

[0014] Preferably, a limiting rod located below the horizontal groove and a spring rod located on one side of the vertical groove are fixedly connected to the surface of the vertical plate. A clamping block is fixedly connected to the free end of the spring rod, and one side of the clamping block close to the arc-shaped groove is inclined.

[0015] A production method of a hot rolling device for nickel-based target materials with adjustable rolling force includes the following steps: S1. Heating the metal material: First, place the metal material in a heating furnace and heat it to a certain temperature. S2. Adjusting the rolling force of the device: Drive the long rod in the vertical state to move up and down, so that the rectangular plate at one end of the long rod enters the rectangular box, and when the rectangular box makes a piston movement, external air can be inhaled into the rectangular box through the air pipe and the second air valve, and then conveyed to the pressure box through the first air valve and the bent pipe, so that the air pressure in the pressure box increases, and the rolling force of the second rolling roll also increases. S3. Conveying the material to be rolled: Through the conveying mechanism, the long rod can be driven to be in a horizontal state, and the long rod and the rectangular plate can be driven to reciprocate along the horizontal direction to convey the material to be rolled placed on the platform.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the adjusting mechanism, the long rod in the vertical state can be driven to move up and down, so that the rectangular plate at one end of the long rod enters the rectangular box, and when the rectangular box makes a piston movement, external air can be inhaled into the rectangular box through the air pipe and the second air valve, and then conveyed to the pressure box through the first air valve and the bent pipe, so that the air pressure in the pressure box increases, and the rolling force of the second rolling roll also increases.

[0017] By setting the conveying mechanism, the long rod can be driven to be in a horizontal state, and the long rod and the rectangular plate can be driven to reciprocate along the horizontal direction to convey the material to be rolled placed on the platform.

[0018] Since the sizes of the materials to be rolled are different, by setting the dispensing mechanism, the two rectangular plates can be driven to move in opposite directions to adjust the distance between the two rectangular plates to adapt to materials to be rolled of different sizes and conduct the conveying work, effectively improving the overall applicability of the device.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Such as Figure 1 And Figure 2As shown in the figure, the present invention provides a hot rolling device for nickel-based targets with adjustable rolling force, including a rolling table 1. On the upper surface of the rolling table 1, two symmetrically distributed bearing plates 21 are vertically fixed. Between the two bearing plates 21, a first rolling roll 22 is rotatably connected. On both of the two bearing plates 21, rectangular sliders 23 are slidably connected. Between the two rectangular sliders 23, a second rolling roll 24 is rotatably connected.

[0023] The nickel-based target to be rolled is sent between the first rolling roll 22 and the second rolling roll 24. The first rolling roll 22 and the second rolling roll 24 rotate in opposite directions, and the rolling work of the nickel-based target can be carried out.

[0024] Above the rolling table 1, an adjusting mechanism for adjusting the rolling force between the first rolling roll 22 and the second rolling roll 24, and a conveying mechanism for conveying the material to be rolled are provided.

[0025] As Figure 2 shown, the adjusting mechanism includes two symmetrically distributed support rods 31 fixed on the upper surface of the rolling table 1. Between the two support rods 31, a pneumatic box 32 is fixedly connected. The lower surface of the pneumatic box 32 is an open structure, and a rectangular piston plate 33 is arranged inside the pneumatic box 32. On the upper surfaces of the two rectangular sliders 23, connecting plates 34 are fixedly connected. One ends of the two connecting plates 34 far from the rectangular sliders 23 are fixed on the lower surface of the rectangular piston plate 33.

[0026] With the above scheme, the higher the air pressure inside the pneumatic box 32, the greater the downward force on the second rolling roll 24, and the greater the rolling force of the device.

[0027] As Figure 2 and Figure 3 shown, two symmetrically distributed bending pipes 35 fixedly connected to the surface of the pneumatic box 32 and communicating with its interior are provided. The free ends of the bending pipes 35 extend below the rolling table 1 and are fixedly connected to a rectangular box 36 communicating with it. The upper surface of the rectangular box 36 is an open structure. An air pipe 37 communicating with its interior is fixedly connected to the bending pipe 35. A first air valve 38 is installed on the bending pipe 35, and a second air valve 39 is installed on the air pipe 37.

[0028] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, two symmetrically distributed sliding rods 310 are slidably connected to the upper surface of the rolling table 1. The upper ends of the two sliding rods 310 are fixedly connected with vertical plates 311. A disc 312 is rotatably connected to the surface of the vertical plate 311. Two symmetrically distributed limit blocks 313 are fixedly connected to the surface of the disc 312. A long rod 314 is slidably connected between the two limit blocks 313. One end of the long rod 314 is integrally fixed with a rectangular plate 315 adapted to the rectangular box 36.

[0029] Among them, a rectangular groove for the movement of the long rod 314 and the rectangular plate 315 is formed on the surface of the rolling table 1; When the rectangular plate 315 moves downward into the rectangular box 36 and performs a piston motion in the rectangular box 36, external air can be inhaled into the rectangular box 36 through the air pipe 37 and the second air valve 39, and then conveyed to the air pressure box 32 through the first air valve 38 and the bent pipe 35, so that the air pressure in the air pressure box 32 increases, and the rolling force of the second rolling roll 24 also increases.

[0030] Such as Figure 4 、 Figure 6 and Figure 7 As shown, a vertical groove 316 is formed on the surface of the vertical plate 311. A cylindrical rod 317 is vertically fixed at the upper end of the long rod 314. A free end of the cylindrical rod 317 is fixedly connected with a cylindrical rod 318 that is slidably adapted to the vertical groove 316. One end of the cylindrical rod 318 away from the cylindrical rod 317 is fixedly connected with a circular plate 319. A strip-shaped frame 320 is rotatably connected to the surface of the vertical plate 311, and the cylindrical rod 317 is slidably adapted to the strip-shaped frame 320.

[0031] Among them, the circular plate 319 is attached to the surface of the vertical plate 311, which can prevent the cylindrical rod 318 from detaching from the vertical groove 316.

[0032] Such as Figure 8 、 Figure 9 and Figure 10 As shown, the conveying mechanism includes a vertical rod 41 vertically fixed on the upper surface of the rolling table 1. The upper end of the vertical rod 41 is fixedly connected with a platform 42. A horizontal groove 43 perpendicular to the vertical groove 316 is formed on the vertical plate 311, and an arc-shaped groove 44 communicating with the vertical groove 316 and the horizontal groove 43. The center positions of the arc-shaped groove 44 and the disc 312 are at the same point, and the cylindrical rod 318 is slidably adapted to both the arc-shaped groove 44 and the horizontal groove 43.

[0033] Among them, the platform 42 is used to carry the material to be rolled; Adopting the above scheme, the long rod 314 can be pushed by the rotation of the strip-shaped frame 320 and move along the arc-shaped groove 44 to a state parallel to the horizontal groove 43, so that the long rod 314 is in a horizontal state, and the reciprocating swing of the strip-shaped frame 320 can drive the long rod 314 to reciprocate along the horizontal groove 43; At this time, the long rod 314 and the rectangular plate 315 reciprocate horizontally, and the rectangular plate 315 can push the material to be rolled placed on the platform 42 between the first rolling roll 22 and the second rolling roll 24 to complete the conveying work.

[0034] A dispensing mechanism is arranged above the rolling table 1.

[0035] Since the sizes of the materials to be rolled vary, by setting up a dispensing mechanism, the two rectangular plates 315 can be driven to move in opposite directions, adjusting the distance between the two rectangular plates 315 to adapt to materials to be rolled of different sizes and conveying them, effectively improving the overall applicability of the device.

[0036] As Figure 11 shown, the dispensing mechanism includes L-shaped plates 51 vertically fixed on the upper surface of the rolling table 1. Between the two L-shaped plates 51, two coaxially fixed threaded rods 52 are rotatably connected, and the thread directions on the surfaces of the two threaded rods 52 are opposite. Through holes are formed in both vertical plates 311, and internally threaded sleeves 53 fixedly connected thereto are respectively penetrated. The two internally threaded sleeves 53 are respectively sleeved on the two threaded rods 52 and are threadedly connected to the threaded rods 52.

[0037] As Figure 10 and Figure 11 shown, on both L-shaped plates 51, gears 54 coaxially fixed to the threaded rods 52 are rotatably connected. An activity groove 55 is formed on the surface of the long rod 314. At both ends inside the activity groove 55, first magnetic attraction blocks are provided. A magnetic force rod 56 is slidably connected inside the activity groove 55. One end of the magnetic force rod 56 is fixedly connected to an arc-shaped toothed plate 57.

[0038] Among them, the magnetic force rod 56 can be adsorbed by the first magnetic attraction blocks inside the activity groove 55 at the end of the activity groove 55, and the arc-shaped toothed plate 57 can be meshed with the gear 54; Among them, the first magnetic attraction blocks are not shown in the figure.

[0039] As Figure 9 and Figure 12 shown, on the surface of the vertical plate 311, a limiting rod 58 located below the horizontal groove 43 and a spring rod 59 located on one side of the vertical groove 316 are fixedly connected. The free end of the spring rod 59 is fixedly connected to a clamping block 510. One side of the clamping block 510 close to the arc-shaped groove 44 is inclined.

[0040] By setting up an adjustment mechanism, the long rod 314 in the vertical state can be driven to move up and down, enabling the rectangular plate 315 at one end of the long rod 314 to enter the rectangular box 36. And when a piston motion is performed in the rectangular box 36, external air can be inhaled into the rectangular box 36 through the air pipe 37 and the second air valve 39, and then conveyed to the air pressure box 32 through the first air valve 38 and the bent pipe 35, increasing the air pressure inside the air pressure box 32 and also increasing the rolling force of the second rolling roller 24.

[0041] By setting up a conveying mechanism, the long rod 314 can be driven to be in a horizontal state, and the long rod 314 and the rectangular plate 315 can be driven to reciprocate along the horizontal direction to convey the materials to be rolled placed on the platform 42.

[0042] As Figure 13As shown in the figure, a production method of a hot rolling equipment for nickel-based target materials with adjustable rolling force includes the following steps: S1. Heating the metal material: First, place the metal material in a heating furnace and heat it to a certain temperature. S2. Adjusting the rolling force of the equipment: Drive the long rod 314 in the vertical state to move up and down, so that the rectangular plate 315 at one end of the long rod 314 enters the rectangular box 36 and makes a piston movement in the rectangular box 36, which can suck external air into the rectangular box 36 through the air pipe 37 and the second air valve 39, and then transport it to the air pressure box 32 through the first air valve 38 and the bent pipe 35, so that the air pressure in the air pressure box 32 increases, and the rolling force of the second rolling roll 24 also increases. S3. Transporting the material to be rolled: Through the conveying mechanism, the long rod 314 can be driven to a horizontal state, and the long rod 314 and the rectangular plate 315 can be driven to reciprocate along the horizontal direction to transport the material to be rolled placed on the platform 42.

[0043] The working principle and usage process of the present invention: When it is necessary to increase the rolling force between the first rolling roll 22 and the second rolling roll 24, the bar-shaped frame 320 is driven by a motor to rotate reciprocally. The bar-shaped frame 320 can push the first cylindrical rod 317, the second cylindrical rod 318, the circular plate 319 and the long rod 314 to reciprocate up and down along the vertical groove 316. The long rod 314 can drive the rectangular plate 315 fixed at one end to reciprocate along the vertical direction, so that the rectangular plate 315 enters the rectangular box 36 and makes a piston movement in the rectangular box 36, which can suck external air into the rectangular box 36 through the air pipe 37 and the second air valve 39, and then transport it to the air pressure box 32 through the first air valve 38 and the bent pipe 35, so that the air pressure in the air pressure box 32 increases, and the rolling force of the second rolling roll 24 also increases.

[0044] When it is necessary to complete the conveying work of the material to be rolled, the bar-shaped frame 320 rotates to push the first cylindrical rod 317, the second cylindrical rod 318, the circular plate 319 and the long rod 314 to move along the arc-shaped groove 44, so that the first cylindrical rod 317, the second cylindrical rod 318 and the circular plate 319 move to the connection of the arc-shaped groove 44 and the horizontal groove 43. At this time, the bar-shaped frame 320 swings reciprocally, pushing the first cylindrical rod 317, the second cylindrical rod 318, the circular plate 319 and the long rod 314 to reciprocate along the horizontal groove 43. The long rod 314 can drive the rectangular plate 315 to reciprocate along the horizontal direction accordingly, so that the rectangular plate 315 pushes the material to be rolled placed on the platform 42 between the first rolling roll 22 and the second rolling roll 24 to complete the conveying work. When it is necessary to adjust the distance between the two rectangular plates 315 according to the size of the material to be rolled, the long rod 314 drives the arc-shaped tooth plate 57 to move towards the side close to the limit rod 58 through the magnetic rod 56. After the magnetic rod 56 moves to one side of the limit rod 58, it will be restricted by the limit rod 58, so as to push the magnetic rod 56 and the arc-shaped tooth plate 57 towards the other end of the movable groove 55, as Figure 9 and Figure 10 shown in the state. At this time, the center position of the arc-shaped tooth plate 57 is the same origin as the disk 312 and the arc-shaped groove 44; Then the strip-shaped frame 320 pushes the long rod 314 to move along the arc-shaped groove 44. The long rod 314 can drive the arc-shaped tooth plate 57 to rotate along the arc-shaped groove 44 through the magnetic rod 56. When the arc-shaped tooth plate 57 rotates, it can mesh with the gear 54 and drive the gear 54 to rotate. The gear 54 can drive the threaded rod 52 fixed coaxially with it to rotate accordingly. The threaded rod 52 can drive the vertical plate 311 to move horizontally through the internal thread sleeve 53. The vertical plate 311 can drive the long rod 314 and the rectangular plate 315 to move horizontally accordingly, so that the two rectangular plates 315 move to a position adapted to the size of the material to be rolled; When the long rod 314 is in a vertical state, the magnetic rod 56 is just above the block 510. When the long rod 314 drives the magnetic rod 56 and the arc-shaped tooth plate 57 to move downward along the vertical groove 316, the magnetic rod 56 will abut against the inclined surface of the block 510 and push the block 510 to move away from the vertical groove 316, so that the magnetic rod 56 can move smoothly below the block 510; When the long rod 314 drives the arc-shaped tooth plate 57 to move upward through the magnetic rod 56, the magnetic rod 56 will be stuck by the block 510 and cannot move upward, so that the magnetic rod 56 slides to the other end of the movable groove 55 and is attracted by the first magnetic block. At this time, the center position of the arc-shaped tooth plate 57 is no longer at the same point as the centers of the arc-shaped groove 44 and the disk 312. Then when the arc-shaped tooth plate 57 rotates along the arc-shaped groove 44 at this time, it cannot mesh with the gear 54.
