Description

Technical Field

[0001] The present invention relates to the technical field of flange heat treatment, and specifically, it is a flange heat treatment device. Background Art

[0002] As an important connecting component in mechanical equipment, flange plates are widely used in fields such as petrochemical, electric power, shipbuilding, and construction. With the continuous development of industrial technology, the performance requirements for flange plates are getting higher and higher. Heat treatment, as one of the key processes to improve the mechanical properties of flange plates, directly affects the service life and safety of flange plates.

[0003] However, in the actual production process, due to the large size of flange plates, deformation problems are likely to occur during the heat treatment process. This not only affects the machining accuracy of flange plates but also reduces their service life and safety. To solve this problem, some devices for flange plate heat treatment have emerged on the market currently, but most of these devices have the following problems:

[0004] 1. The heat treatment efficiency and effect are not good. Existing heat treatment devices generally stack multiple flange plates for unified annealing, resulting in uneven temperature distribution inside the flange plates, which leads to inconsistent heat treatment effects on different parts of the flange plates and affects the overall performance of the flange plates.

[0005] 2. When existing heat treatment devices perform annealing operations on flange plates, due to temperature changes, it is easy to cause deformation of the flange plates, affecting the performance and qualification rate of the finished products.

[0006] For example, an annealing device for flange plate heat treatment with the Chinese patent publication number CN213835433U belongs to the technical field of heat treatment annealing. It includes an annealing box. One side of the annealing box is fixedly sleeved with a fixed block. A screw rod is movably sleeved inside the fixed block. A threaded block is threadedly sleeved on the outer part of the screw rod. A first positioning rod is movably sleeved inside the threaded block. One end of the screw rod is fixedly installed with a crank. The middle part of the crank is threadedly connected with a locking plate through a bolt. One side of the locking plate is fixedly connected with a baffle plate. The bottom end of the locking plate is fixedly connected with a support seat. In this annealing device for flange plate heat treatment, by setting a motor, a motor seat, a driving wheel, a driving shaft, a support rod, a driven shaft, a driven wheel, a steel track belt, and a load-bearing seat, during the use of the annealing device, it is convenient to heat the materials piece by piece, thus effectively improving the heating effect of the materials and effectively improving the product quality.

[0007] However, in this application, there is no clamping module for flange plates. The flange plates are laid flat on the steel track belt, resulting in a small number of flange plates processed in a single time by the device and low processing efficiency.

[0008] Therefore, the present application provides a flange heat treatment device to solve the problems of low processing efficiency, poor processing effect, and easy deformation of the flange during the heat treatment process in the prior art. Summary of the Invention

[0013] As an optimization, the first correction rollers are arranged along the diameter direction of the heat treatment outer shell, the guiding ends face the axis of the heat treatment outer shell, and the guiding ends of the two first correction rollers are arranged adjacent to each other.

[0014] As an optimization, an arc-shaped detection bracket is arranged inside the fixed outer shell. The detection bracket is configured with a plurality of first detection rollers. The first detection rollers are arranged vertically, and the roller surfaces of the first detection rollers are in contact with the outer circumference of the flange;

[0015] The fixed outer shell is configured with a plurality of first telescopic rods. The extended ends of the first telescopic rods are connected to the detection bracket. The first telescopic rods are in an extended state, so that the first detection rollers are always in contact with the flange.

Detailed implementation manners

[0034] As Figures 1-9 In the illustrated embodiment, a flange heat treatment device includes a heat treatment housing and a straightening portion disposed inside the heat treatment housing. The heat treatment housing includes a fixed housing 1 and a movable housing 2. A telescopic cylinder 3 is connected to the outside of the movable housing 2, and the telescopic cylinder 3 can drive the movable housing 2 to approach / separate from the fixed housing 1;

[0035] The straightening portion includes a first straightening assembly disposed inside the fixed housing 1 and a second straightening assembly disposed inside the movable housing 2. The straightening portion can clamp and straighten a plurality of flanges 4, so that the plurality of flanges 4 are evenly spaced and can rotate in the horizontal direction. A heat treatment space 5 is formed between adjacent flanges 4, and the first straightening assembly and the second straightening assembly divide the heat treatment space 5 into several annealing zones with different temperatures.

[0036] The heat treatment housing further includes a top and a bottom housing. There is a cylindrical cavity inside the heat treatment housing, and clamping and straightening operations can be performed on flanges 4 of different sizes.

[0037] The movable housing 2 can be pulled outwards, the flange 4 is placed into the fixed housing 1, the flange 4 is clamped by the first straightening assembly, and then the movable housing 2 is docked and installed with the fixed housing 1.

[0038] The telescopic cylinder 3 is horizontally arranged, and the axis of the telescopic rod passes through the axis of the heat treatment housing.

[0039] As Figure 6And Figure 9 As shown in Figure 9 , the first correction assembly includes two first correction parts arranged in a V shape. Each first correction part includes a vertically arranged first mounting bracket 6 and a plurality of first correction rollers 7. The plurality of first correction rollers 7 are evenly arranged along the height direction of the first mounting bracket 6. The first correction rollers 7 are configured with first correction motors 8, and the outer ends of the first correction rollers 7 converge to form guiding ends 9.

[0040] The guiding ends 9 of two relatively arranged first correction rollers 7 are adjacent or in contact with each other, and this does not affect the rotation of the first correction rollers 7. The first correction motor 8 can drive the first correction rollers 7 to rotate. The first correction rollers 7 on the same side of the flange 4 rotate in the same direction, and the first correction rollers 7 on both sides of the flange 4 rotate in opposite directions, which can drive the flange 4 to rotate.

[0041] As Figure 6 shown in Figure 6 , the first correction rollers 7 are arranged along the diameter direction of the heat treatment housing, and the guiding ends 9 face the axis of the heat treatment housing. The guiding ends 9 of the two first correction rollers 7 are adjacent to each other.

[0042] As Figure 6 and Figure 9 shown in Figure 9 , an arc-shaped detection bracket 10 is arranged inside the fixed housing 1. The detection bracket 10 is configured with a plurality of first detection rollers 11. The first detection rollers 11 are arranged vertically, and the roller surfaces of the first detection rollers 11 are in contact with the outer periphery of the flange 4.

[0043] The fixed housing 1 is configured with a plurality of first telescopic rods 12. The extended ends of the first telescopic rods 12 are connected to the detection bracket 10. The first telescopic rods 12 are in an extended state, so that the first detection rollers 11 are always in contact with the flange 4. A first distance sensor is arranged inside the fixed housing 1, and the first distance sensor is used to detect the distance between the detection bracket 10 and the inner wall of the fixed housing 1.

[0044] The first telescopic rods 12 are used to push the first detection rollers 11 to stably contact a plurality of flanges arranged vertically side by side, and can detect the roundness diameter of the flange 4. When the position of the first detection rollers 11 changes, it indicates that there are certain defects in the roundness of the flange 4. At the same time, the first detection rollers 11 can push the flange 4 to make the flange always coaxial with the heat treatment housing, avoiding the position of a certain flange 4 from shifting, and ensuring that each flange 4 is in the same position in the vertical direction.

[0045] As Figure 5 shown in Figure 5 , the movable housing 2 is configured with a second detection roller 13. The second detection roller 13 is arranged vertically. The outside of the movable housing 2 is configured with a second telescopic rod 14, and the second telescopic rod 14 is used to push the second detection roller 13 to contact the outer periphery of the flange 4.

[0046] A second distance sensor is provided on the inner side of the movable housing 2, and the second distance sensor is used to detect the distance between the second detection roller 13 and the inner wall of the movable housing 2.

[0047] The second detection roller 13 is arranged opposite to the first detection roller 11, so that the multiple flange plates 4 are stressed stably. The extending ends of the first telescopic rod 12 and the second telescopic rod 14 are both arranged towards the axis of the heat treatment housing.

[0048] To improve the detection effect on the flange, a plurality of outwardly telescopic detection rings can be arranged outside the first detection roller 11 and the second detection roller 13, and the plurality of detection rings are respectively in contact with the flange plate 4; at the same time, the detection ring can also be configured with a distance detection module for detecting the position change of the detection ring, so as to improve the accuracy of the curvature detection of the flange plate 4.

[0049] As Figure 6 shown, the second correction assembly includes second correction parts arranged in parallel. The second correction part includes a second mounting frame 15 and a plurality of second correction rollers 16. The plurality of second correction rollers 16 are uniformly arranged along the height direction of the second mounting frame 15, and the second correction rollers 16 are configured with second correction motors;

[0050] The outer end of the second correction roller 16 extends to the outside of the middle part of the first correction roller 7, and the second correction roller 16 is arranged adjacent to the first correction roller 7.

[0051] The rotation directions of the first correction roller 7 and the second correction roller 16 on the same side of the flange plate 4 are the same, which can drive the flange plate 4 to rotate smoothly around the axis of the heat treatment housing. The length of the second correction roller 16 is not less than the radius of the flange plate 4. The first correction roller 7 and the second correction roller 16 can stably clamp and press the flange plate 4, and can uniformly correct the flange plate 4.

[0052] As Figure 3 shown, the annealing zone includes a first annealing zone 17, a second annealing zone 18, a third annealing zone 19 and a fourth annealing zone 20 arranged in sequence along the rotation direction of the flange plate 4. The first annealing zone 17 is located between the first correction assembly and the second correction assembly, and the third annealing zone 19 is located between the first correction assembly and the fixed housing 1.

[0053] Due to the contact clamping between the first straightening roller 7, the second straightening roller 16 and the flange 4, the internal space of the heat treatment shell can be partitioned. The temperature of the first annealing zone 17 is the highest; the second annealing zone 18, the fourth annealing zone 20 are arranged adjacent to the first annealing zone 17, and their temperatures are lower than that of the first annealing zone 17; after the flange 4 is heat-treated inside the first annealing zone 17, it rotates into the second annealing zone 18. Therefore, the temperature of the second annealing zone 18 is higher than the temperatures of the third annealing zone 19 and the fourth annealing zone 20.

[0054] To improve the annealing effect, the temperature inside the annealing zones can be appropriately adjusted. Heating or cooling modules can be connected to the second annealing zone 18, the third annealing zone 19 and the fourth annealing zone 20 to improve the heat treatment effect.

[0055] As Figure 2 shown, both the fixed shell 1 and the movable shell 2 are semi-circular. An air inlet pipe 21 is connected to the middle of the movable shell 2. The air inlet pipe 21 is used to blow heat treatment medium into the annealing zones, and the movable shell 2 is provided with an exhaust port 22.

[0056] Usage method:

[0057] When the device is specifically used, first shorten the telescopic cylinder 3. The telescopic cylinder 3 drives the movable shell 2 to move outwards, and the heat treatment shell opens;

[0058] Put a plurality of flanges 4 one by one between the upper and lower first straightening rollers 7. Clamp the flange 4 through the first straightening roller 7, so that the guiding end 9 of the first straightening roller 7 is located at the axis center of the flange 4;

[0059] After the flanges 4 are placed, extend the telescopic cylinder 3 to dock the movable shell 2 with the fixed shell 1, and the second straightening roller 16 extends into the space between two adjacent flanges 4;

[0060] Drive the first straightening roller 7 to rotate through the first straightening motor 8, drive the second straightening roller 16 to rotate through the second straightening motor, and drive the flange 4 to rotate slowly through the first straightening roller 7 and the second straightening roller 16;

[0061] Pass hot air into the first annealing zone 17 through the air inlet pipe 21 to perform heat treatment operations on the flange 4. The flange 4 rotates slowly, so that different positions of the flange 4 pass through multiple annealing zones in sequence, improving the annealing effect;

[0062] During the annealing process, clamp and squeeze the flange 4 through the first straightening roller 7 and the second straightening roller 16 to prevent the flange 4 from deforming and keep the flange 4 flat.

[0063] During the above heat treatment process, the first detection roller 11 is pushed by the first telescopic rod 12, and the second detection roller 13 is pushed by the second telescopic rod 14, so that the first detection roller 11 and the second detection roller 13 tightly squeeze the flange 4, avoiding the displacement of the position of the flange 4, and making multiple flanges 4 always located in the same temperature range;

[0064] Meanwhile, the arrangement of the first detection roller 11 and the second detection roller 13 can detect the radius, curvature, etc. of the flange 4, and the position changes of the first detection roller and the second detection roller 13 can be detected by the first distance sensor and the second distance sensor.
