DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the quenching furnace cooling device according to an embodiment of the present application with reference to the accompanying drawings.

[0029] like Figure 1-7 As shown, the quenching furnace cooling device of the embodiment of the present application includes:

[0030] Tube feeding device 1, which is set at the feeding port of atmosphere cooling device 2:

[0031] The atmosphere cooling device 2 includes a feeding mechanism 6 and an atmosphere mechanism 7. The air outlet of the atmosphere mechanism 7 surrounds the material transport track of the feeding mechanism 6. The feeding mechanism 6 and the atmosphere mechanism 7 are arranged in a sealed furnace.

[0032] Feeding mechanism 6, the feeding mechanism 6 includes a conveying frame 201 and a screw bearing seat 204, wherein,

[0033] The screw bearing seat 204 is arranged inside the sealed furnace. The center of the screw bearing seat 204 is rotatably connected to the ball screw 203, and the ball screw moving block 202 is connected to the conveying frame 201.

[0034] A frame slide rail 211 is provided in the sealing furnace, and the transfer frame 201 slides on the frame slide rail 211 through the slider 210 .

[0035] The conveying frame 201 is internally rotatably connected to multiple groups of second shafts 205, and the second shafts 205 are provided with two groups of symmetrically arranged second conical rollers 206. The outer wall of the conveying frame 201 is provided with a feeding motor 207, and the output end of the feeding motor 207 is connected to the end of one group of second shafts 205.

[0036] Atmosphere mechanism 7, atmosphere mechanism 7 includes arc diffusion frame 212, wherein,

[0037] The arc diffusion frame 212 is set inside the sealed furnace through the frame fixing frame 214. Multiple groups of connected atmosphere nozzles 215 are set on the inner side of the arc diffusion frame 212. One end of the arc diffusion frame 212 is connected to an input pipe 213, and the input pipe 213 is connected to the multiple groups of atmosphere nozzles 215. The input end of the input pipe 213 is connected to the gas valve connecting pipe 216, and the gas valve connecting pipe 216 is connected to the external atmosphere source.

[0038] Specifically, the feeding motor 105 of the tube feeding device 1 drives the first shaft 101 to rotate, and through the intermittent transmission of the first double-wheel ratchet 103 and the first ratchet chain 104, the tubes on the feeding platform 106 are pushed to the feeding port of the atmosphere cooling device 2 in turn and received by the feeding mechanism 6.

[0039] Atmosphere Cooling Process: Feed motor 207 drives ball screw 203 to rotate within screw bearing housing 204. Ball screw moving block 202 converts this rotational motion into linear motion, driving conveyor frame 201 to move horizontally along frame rails 211. The pipe is supported by second tapered rollers 206 and moves synchronously with the conveyor frame, moving the material into the sealing furnace, which is then sealed.

[0040] Atmosphere injection: External atmosphere sources such as nitrogen and inert gas enter the arc diffusion frame 212 through the air valve connecting pipe 216 and the input pipe 213, and are evenly sprayed along the length direction of the conveying frame 201 through multiple groups of atmosphere nozzles 215 inside, forming a cooling air curtain around the pipe material transportation track.

[0041] In one embodiment of the present application, the oil tank 3, the material transfer device 4, the oil cooling mechanism 5 and the circulation mechanism 8 are further included. The material transfer device 4 is arranged inside the oil tank 3, the oil cooling mechanism 5 is arranged inside the oil tank 3, and the circulation mechanism 8 is arranged outside the oil tank 3.

[0042] The material transfer device 4 includes multiple sets of tapered roller shafts 401, a second double-wheel ratchet 402, a second ratchet chain 403, and a material transfer motor 404. The tapered roller shafts 401 are rotatably connected to the interior of the oil pool 3. The ends of the tapered roller shafts 401 are connected to the second double-wheel ratchet 402, and adjacent second double-wheel ratchet 402 are connected by the second ratchet chain 403. The material transfer motor 404 is installed outside the oil pool and is connected to the end of one set of tapered roller shafts 401.

[0043] The oil cooling mechanism 5 includes multiple sets of ring frames 501, suction pipes and oil valves 502, and oil pipes 503. The center of the ring frames 501 coincides with the conveying center of the material conveying device 4. The multiple sets of ring frames 501 are fixed inside the oil pool 3. The inner side of the ring frames 501 is provided with multiple sets of oil spray holes 504. The bottom of the ring frames 501 is connected to the suction pipe 502. The opening of the suction pipe 502 is set inside the oil pool 3. The outer side of the ring frames 501 is provided with an oil pipe 503. The input end of the oil pipe 503 is connected to the suction pipe 502, and the output end of the oil pipe 503 is connected to the oil spray hole 504.

[0044] The circulation mechanism 8 includes a circulation pipe 801 and a circulation pump 802. One end of the circulation pipe 801 is connected to the oil pool 3, and the other end of the circulation pipe 801 is communicated with multiple sets of ring frames 501 respectively. The circulation pump 802 is arranged on the circulation pipe 801.

[0045] The cooled pipe is transferred from the conveyor frame 201 to the oil pool 3. The tapered roller 401 of the conveyor device 4, driven by the second double-wheel ratchet 402 and the second ratchet chain 403, moves the pipe within the oil pool 3. Simultaneously, the circulating pump 802 of the circulation mechanism 8 delivers cooling oil from the oil pool through the circulation pipe 801 to the ring frame 501 of the oil cooling mechanism 5. The oil is then sprayed onto the pipe surface through the inner oil spray holes 504, achieving deep quenching and cooling. The sprayed oil then flows back to the oil pool through the suction pipe 502, completing the cycle.

[0046] During actual operation, the circulation pump 802 delivers 40° C. quenching oil PAG to the ring frame 501 through the circulation pipe 801 at a flow rate of 30 L / min.

[0047] The oil is sprayed from the circumferential oil spray hole 504 at a pressure of 0.5 MPa, and the surface temperature of the pipe drops sharply to below 150° C., forming a martensitic structure.

[0048] Oil recovery: The sprayed oil flows back to the oil pool 3 through the suction pipe 502, and is cooled by a cooler (not mentioned) before being recycled.

[0049] In one embodiment of the present application, the tube feeding device 1 includes a feeding platform 106, multiple sets of first shafts 101 and first conical rollers 102, wherein:

[0050] Multiple groups of first shafts 101 are rotatably connected to the loading platform 106. Two groups of symmetrically arranged first conical transfer rollers 102 are provided on the outer wall of the first shaft 101. The ends of the first shafts 101 are connected to first double-wheel ratchets 103. Adjacent first double-wheel ratchets 103 are connected through a first ratchet chain 104. A loading motor 105 is provided on the outer wall of the loading platform 106. The output end of the loading motor 105 is connected to the end of one group of first shafts 101.

[0051] Specifically, the device drives the first shaft 101 through the feeding motor 105, and uses the intermittent transmission of the first double-wheel ratchet 103 and the first ratchet chain 104 to make multiple sets of symmetrically arranged first conical rollers 102 drive the pipes one by one to the front end of the feeding platform 106, so as to realize the orderly feeding of the pipes and avoid accumulation.

[0052] The symmetrical layout of the first conical transfer roller 102 ensures uniform force on both sides of the pipe, avoids deviation or tilting during transmission, and ensures that the pipe moves smoothly along the central axis. The conical structure generates centripetal thrust on the pipe when rotating, which can automatically correct the position of the pipe, facilitating subsequent processes such as precise positioning of the atmosphere cooling device.

[0053] In one embodiment of the present application, the feeding mechanism 6 also includes a wire guide rail 208 and a motor wire slider 209. The wire guide rail 208 is arranged inside the sealing furnace. The motor wire slider 209 slides on the wire guide rail 208. The motor wire slider 209 is provided with a motor wire slot.

[0054] Specifically, the mechanism provides a mobile power supply channel for the motor of the conveyor frame 201 through the sliding cooperation of the wire guide rail 208 and the motor wire slider 209. The motor wire slot is used to fix the cable so that the cable moves synchronously with the slider.

[0055] In one embodiment of the present application, the ring frame 501 of the oil cooling mechanism 5 is annular, and the oil spray holes 504 are distributed circumferentially along the inner side of the ring frame 501 .

[0056] Specifically, the annular ring frame 501 fits coaxially with the pipe, and the circumferentially distributed oil spray holes 504 inside ensure uniform spraying of cooling oil across the entire circumference of the pipe, avoiding localized cooling blind spots. This design evenly distributes the impact force of the oil along the circumference of the pipe, ensuring consistent surface hardness after quenching. Furthermore, the annular structure guides the oil back to the oil pool 3 quickly, improving cooling efficiency and oil recycling.

[0057] In one embodiment of the present application, the atmosphere nozzles of the atmosphere mechanism 7 are distributed along the length direction of the conveying frame 201 .

[0058] Specifically, the atmosphere nozzles are distributed along the length of conveyor frame 201, ensuring that all parts of the pipe surface are continuously exposed to the cooling atmosphere throughout its entire travel, avoiding blind cooling spots caused by the conveyor trajectory. This layout synchronizes the atmosphere injection path with the pipe's travel direction, creating a "full-coverage" cooling effect. This is particularly suitable for uniform quenching of long pipes, improving the consistency and stability of the cooling process.

[0059] Specifically, pipe feeding: the pipe feeding device 1 pushes the pipes one by one to the feed port of the atmosphere cooling device 2 through intermittent transmission.

[0060] Atmosphere cooling: The feeding mechanism 6 feeds the pipe into the sealed furnace, the pipe moves while rotating, and the atmosphere mechanism 7 sprays cooling gas to complete pre-cooling.

[0061] Oil cooling: The cooled pipe enters the oil pool 3, the material transfer device 4 drives the pipe to move, and the oil cooling mechanism 5 sprays circulating cooling oil to achieve deep quenching.

[0062] Circulation and recycling: The oil returns to the oil pool for reuse after treatment. The whole process is automated to ensure uniform cooling of the pipes.

[0063] In summary, the quenching furnace cooling device of the present embodiment significantly improves the uniformity and production efficiency of pipe quenching through the coordinated design of a multi-stage cooling and transmission system. First, the staged treatment of atmosphere cooling and oil cooling allows for precise control of the cooling gradient for different pipe materials, avoiding the limitations of a single cooling method and ensuring surface hardness and structural uniformity.
