[0003] A Chinese patent document with authorization announcement number CN220224235U proposes a rotary wind and mist quenching device for high-temperature heat treatment of castings, including a first spray assembly, a rotating disk assembly and a drive motor. The first spray assembly is arranged on the side of the rotating disk assembly and is used to perform wind and mist quenching treatment on the castings. The rotating disk assembly includes a base and a rotating disk mounted on the base. The drive motor is used to drive the rotating disk to rotate.

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-3 As shown, the utility model proposes a rotary spray quenching device for high-chromium wear-resistant cast iron parts, including a frame 1, a clamping assembly 2 and a spray assembly 3. The clamping assembly 2 is arranged on the frame 1, clamps the cast iron part and drives it to rotate. The spray assembly 3 is arranged on the frame 1, and sprays and quenches the cast iron part by reciprocating up and down. The clamping assembly 2 includes a rotating part 21 that drives the cast iron part to rotate; and a clamping part 22 that clamps the cast iron part at multiple points from four sides. The spray assembly 3 includes a spray part 31 that performs annular spray quenching on the cast iron part; and a moving part 32 that drives the spray part 31 to reciprocate up and down.

[0024] Further explanation, the rotating member 21 includes a driving mechanism 211 disposed on the frame 1; the driving mechanism 211 is a motor; the driving end of the driving mechanism 211 is connected to a turntable 212; a plurality of connecting columns 213 are disposed on the upper end of the turntable 212; and a placement plate 214 is commonly connected to the upper ends of the plurality of connecting columns 213. The clamping member 22 and the cast iron part can be driven to rotate together, so that the spray can evenly cover the surface of the casting, achieving uniform quenching, and effectively avoiding the problem of uneven local cooling that may occur in the traditional quenching method.

[0025] Further explanation, two groups of clamping members 22 are vertically cross-arranged on the rotating member 21, and the two groups of clamping members 22 do not interfere with each other. The cast iron part is clamped from four sides to make the clamping more stable and prevent the cast iron part from slipping off the clamping members 22 during the rotation process.

[0026] Further explanation, the clamping member 22 includes a fixed block 222 symmetrically arranged at the lower end of the placement plate 214; a left and right screw rod 223 is rotatably connected between the two fixed blocks 222; one end of the left and right screw rod 223 is connected to a second drive mechanism 224, on which a clamping plate 225 is symmetrically threaded; the second drive mechanism 224 is a motor; the two clamping plates 225 are slidably connected to the slide groove 221 symmetrically opened on the placement plate 214; the opposite ends of the two clamping plates 225 are respectively connected to a limit column 226 for fixedly limiting the cast iron part and a limit member 227 for elastically limiting the cast iron part. The limit member 227 includes a sleeve 2271 connected to the clamping plate 225; a sliding column 2272 is slidably connected in the sleeve 2271; and a spring 2273 is connected between the sleeve 2271 and the sliding column 2272. The limiting column 226 and the limiting member 227 cooperate with each other to limit the cast iron part. The limiting column 226 is in direct contact with the cast iron part, and the limiting member 227 is in elastic contact with the cast iron part. While increasing the limiting point, the limiting member 227 can fit the shape of the cast iron part to limit it, so that the clamping member 22 can adapt to cast iron parts of different shapes and is more flexible and extensive in application.

[0027] Further explanation, the limiting column 226 and the sliding column 2272 are vertically arranged in the center, and the opposite ends of the limiting column 226 and the sliding column 2272 on both sides are hemispherical. The limiting column 226, the sliding column 2272 and the cast iron part are all point-connected, which reduces the contact area between the limiting column 226, the sliding column 2272 and the cast iron part, increases the range of the spray that can be sprayed on the cast iron part, and reduces the occurrence of uneven local cooling.

[0028] Embodiment 2

[0029] like Figure 4As shown, the utility model proposes a rotary spray quenching device for high-chromium wear-resistant cast iron parts. Compared with the first embodiment, this embodiment also includes: the moving part 32 includes a driving mechanism 3 321 arranged on the frame 1; the driving mechanism 3 321 is a forward and reverse motor; the driving end of the driving mechanism 321 is connected to a threaded rod 322 rotatably connected to the frame 1; one side of the threaded rod 322 is provided with a sliding rod 325 connected to the frame 1; the upper end of the sliding rod 325 is connected to a limiting plate 323; the limiting plate 323 is rotatably connected to the threaded rod 322; a sliding block 324 is commonly provided on the threaded rod 322 and the sliding rod 325; the sliding block 324 is threadedly connected to the threaded rod 322 and is slidably connected to the sliding rod 325. The spray member 31 includes a spray ring 311 connected to a slider 324; nozzles 312 for spray quenching the cast iron are evenly arranged on the inner side of the spray ring 311, and a water pipe 313 is also connected to the spray ring 311; the other end of the water pipe 313 is connected to a water tank 314 arranged on the frame 1; a water pump is arranged in the water tank 314. The spray member 31 can spray quench the cast iron, and the moving member 32 can drive the spray ring 311 to move up and down, so as to adapt to cast iron parts of different heights, making the application range more flexible and extensive.

[0030] The working principle of the utility model is as follows: when working, the cast iron part is first placed on the placement plate 214, and then the driving mechanism 224 is started to drive the left and right screw rods 223 to rotate, thereby driving the clamping plates 225 on both sides to approach each other, so that the limiting column 226 contacts the surface of the cast iron part and clamps it. At the same time, the spring 2273 will push the sliding column 2272 to abut against the cast iron part, further limiting the cast iron part. Then the driving mechanism 1 211 is started to drive the rotating disk 212 and the placement plate 214 to rotate, thereby driving the cast iron part to rotate. Then the driving mechanism 3 321 is started to drive the threaded rod 322 to rotate, thereby driving the slider 324 and the spray ring 311 to slide back and forth along the slide rod 325. At the same time, the water pump in the water tank 314 is started, so that water is sprayed from the nozzle 312 along the water pipe 313 to the cast iron part, thereby quenching it.

[0031] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
