Technical Field
[0001] This utility model relates to the field of flange processing technology, specifically to a heat treatment device for high neck flanges. Background Technology
[0002] A flange is also called a flange disc or flange. A flange is a part used to connect shafts to each other, and is used for connecting pipe ends. A high neck flange refers to a flange with a high neck. When processing a high neck flange, it is necessary to perform heat treatment using a heat treatment device.
[0003] When using existing heat treatment equipment, workers place the high-neck flange on a platform inside the equipment and heat-treat the high-neck flange through heating components. However, in existing heat treatment equipment, the distance between the placement platform and the heating element is fixed and cannot be adjusted when heat treating high neck flanges. If high neck flanges of different heights are heat treated, the heating element cannot get close enough to the high neck flanges of different heights, resulting in a longer heat treatment time for high neck flanges of different heights, thereby reducing the working efficiency of the heat treatment equipment. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for high neck flanges. This solves the problem that existing heat treatment devices, when heat treating high neck flanges of different heights, cannot effectively bring the heating element close to the flanges because the distance between the placement platform and the heating element is fixed. This results in longer heat treatment times for flanges of different heights, thus reducing the efficiency of the heat treatment device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for high neck flanges, comprising a housing, a heating component fixed to the top of the inner wall of the housing by bolts, a placement platform below the heating component, and a lifting mechanism located at the bottom of the placement platform; a rotating mechanism located inside the housing; and a driving mechanism located on one side of the housing; wherein the lifting mechanism causes the placement platform to move up and down, the rotating mechanism causes the placement platform to rotate the high neck flange, and the driving mechanism drives the lifting mechanism or the rotating mechanism to move.
[0006] Preferably, the lifting mechanism includes a horizontal column, both ends of which are rotatably connected to the inner wall of the housing via bearings; a partition is fixedly connected to the inner wall of the housing; a first bevel gear set is installed on the outer wall of the horizontal column; a rotating column is drivenly connected to the horizontal column via the first bevel gear set; a vertical column is rotatably connected to the inner wall of the rotating column via bearings, and its top is fixedly connected to the bottom of the partition; a gear is fixedly connected to the outer wall of the rotating column; a rack is meshed with one side of the gear, passes through the partition, and is movably connected to the partition; wherein, driven by the horizontal column, the first bevel gear set causes the rotating column to drive the gear to rotate, thereby causing the rack to move.
[0007] Preferably, the rotating mechanism includes a worm gear rotatably connected to the inner wall of the housing via a bearing; a worm wheel meshing with the front side of the worm gear; a column fixedly connected to the inner wall of the worm wheel, and its bottom rotatably connected to the bottom of the inner wall of the housing via a bearing; a hollow column sleeved on the outer wall of the column, with its top extending above the partition plate and its top fixedly connected to the bottom of the placement platform; a connecting plate rotatably connected to the inner wall of the hollow column via a bearing, and its bottom fixedly connected to the top of the rack; and a support portion disposed between the placement platform and the connecting plate. Driven by the worm gear, the worm wheel causes the column to move, thereby rotating the placement platform.
[0008] Preferably, the support includes an annular groove, which is formed on the surface of the connecting plate; the arc-shaped slider is slidably engaged with the inner wall of the annular groove, and its top is fixedly connected to the bottom of the placement platform; wherein, the arc-shaped slider slides in the annular groove under the drive of the placement platform.
[0009] Preferably, the drive mechanism includes a frame fixedly connected to the side wall of the outer casing; a dual-head motor fixedly connected to the side wall of the outer casing via a motor sleeve; two rotating shafts, each located outside the output ends of the dual-head motor; two horizontal plates, each rotatably connected to the outer wall of the two rotating shafts via bearings, and the side wall fixedly connected to the outer wall of the outer casing; two second bevel gear sets, one rotatably connected between one rotating shaft and the horizontal column, and the other rotatably connected between the other rotating shaft and the worm gear; two electric telescopic rods, each fixedly connected to the inner wall of the frame via a fixed sleeve; two sleeves, each sleeved onto the outer wall of the rotating shaft; and two support columns, each fixedly connected to the output ends of the two electric telescopic rods, and rotatably connected to the outer wall of the two sleeves via bearings, with their ends slidably engaged with the inner wall of the frame; wherein, driven by the electric telescopic rods, the support columns cause the sleeves to contact the output shafts of the dual-head motors, thereby causing the rotating shafts to drive the second bevel gear sets to rotate, which in turn causes the horizontal column and the worm gear to rotate.
[0010] Preferably, the surface of the placement platform is provided with fixing components.
[0011] This utility model provides a heat treatment device for high neck flanges, which has the following beneficial effects: This heat treatment device for high-neck flanges achieves height adjustment of the placement platform through the cooperation of a horizontal column, a first bevel gear set, a rotating column, a vertical column, gears, a rack, and a partition. This solves the problem in existing heat treatment devices where the distance between the placement platform and the heating element is fixed. When heat treating high-neck flanges of different heights, the heating element cannot properly approach the flanges, leading to longer heat treatment times and reduced efficiency.
[0012] By coordinating the worm gear, worm wheel, column, hollow column, connecting plate, and support, the placement platform can be rotated, thus ensuring uniform heating of the high neck flange. This solves the problem that when the high neck flange is being heat-treated, it cannot be rotated, causing the part of the high neck flange near the heat source to rapidly absorb heat and rise in temperature, while the area away from the heat source heats up slowly, resulting in uneven heating of the high neck flange.
