Description

Technical Field

[0001] The invention relates to the technical field of tempering furnaces, in particular to a continuous stress relief tempering furnace circulation device. Background Art

[0002] Stress relief tempering is used to eliminate cutting stress and reduce quenching distortion for workpieces with complex shapes, high cutting volumes, and strict dimensional accuracy requirements, such as alloy steel cutting tools and molds. Important parts whose performance (hardness) after heat treatment does not meet the required requirements also require stress relief tempering before rework and quenching to reduce quenching distortion or cracking. Low-temperature tempering can also be performed on workpieces after machining or finishing to eliminate or reduce machining stresses and improve dimensional stability and durability. Currently, stress relief tempering furnaces are commonly used to address this issue.

[0003] At present, the existing stress relief tempering furnace circulation device will discharge internal gas during use. However, since it is necessary to filter the internal impurities, a filter is generally set inside the device to intercept them. However, during long-term use, the surface of the device will be blocked, and staff are generally required to clean and dredge the work, which is very time-consuming and labor-intensive, and the cleaning parts must be cleaned again. Therefore, further improvement is needed.

[0004] Therefore, it is necessary to design a continuous stress relief tempering furnace circulation device that is highly practical and can quickly separate waste chips. Summary of the Invention

[0005] The object of the present invention is to provide a continuous stress relief tempering furnace circulation device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a continuous stress relief tempering furnace circulation device, comprising a tempering furnace body, a telescopic cylinder fixedly connected to the rear side of the tempering furnace body, an impurity cleaning mechanism provided inside the tempering furnace body, a shell fixedly mounted on one side of the exterior of the tempering furnace body, an external connection pipe fixedly mounted on one side of the exterior of the shell, and a prompt cleaning mechanism provided on the top of the external connection pipe;

[0007] The impurity cleaning mechanism includes a sliding screw, which is slidably connected to the inside of the telescopic cylinder. A rotating connecting rod is rotatably connected to the inside of the sliding screw. A gear is fixedly connected to the outside of the rotating connecting rod. A rack plate is provided at the bottom of the gear, so that the gear drives the rotating connecting rod to rotate during the rotation process.

[0008] The rotating connecting rod is fixedly connected to a high-temperature resistant connecting roller on the outside, and a high-temperature resistant fiber is fixedly connected to the outside of the high-temperature resistant connecting roller. One side of the high-temperature resistant connecting roller is fixedly connected to an arc-shaped rotating rod. A movable connecting plate is provided on the top of the high-temperature resistant fiber. A filter screen is embedded in the movable connecting plate. Four sliding blocks are fixedly connected to the outside of the movable connecting plate, so that the movable connecting plate can slide quickly.

[0009] Two movable clamping plates are provided inside the high-temperature resistant connecting roller, and one side of each movable clamping plate is fixedly connected to a cleaning self-cleaning plate. Two counterweight rods are provided inside the high-temperature resistant connecting roller, so that the movable clamping plates drive the cleaning self-cleaning plates to rotate;

[0010] The prompt cleaning mechanism includes a connecting shell, which is fixedly connected to the top of the external connection pipe. A sealing block is slidably connected inside the connecting shell, and a prompt column is fixedly connected to the top of the sealing block.

[0011] According to the above technical solution, the sliding screw extends into the interior of the tempering furnace body, and the outer surface of the sliding screw contacts the interior of the tempering furnace body, which can facilitate the sliding operation of the sliding screw.

[0012] According to the above technical solution, four connecting grooves are opened inside the tempering furnace body, and the four sliding blocks extend into the four connecting grooves respectively and are slidably connected with the four connecting grooves, which can facilitate the sliding of the sliding blocks.

[0013] According to the above technical solution, one side of the rack plate is fixedly connected to a side wall of the inner cavity of the tempering furnace body, and the gear is meshed with the rack plate, which can facilitate the rotation of the gear.

[0014] According to the above technical solution, two sliding grooves are opened on one side of the high temperature resistant connecting roller, and the two movable clamping plates are respectively slidably connected to the inside of the two sliding grooves, which can facilitate the sliding work of the movable clamping plates.

[0015] According to the above technical solution, a plurality of scraping grooves are provided inside the self-cleaning plate, and the number of the scraping grooves corresponds to the number of high-temperature resistant fibers, which can facilitate the cleaning of the high-temperature resistant fibers.

[0016] According to the above technical solution, two arc grooves are provided inside the high temperature resistant connecting roller, and the two counterweight rods are slidably connected to the inside of the two arc grooves respectively, which can facilitate the sliding of the counterweight rods.

[0017] According to the above technical solution, a support frame is fixedly installed on the bottom of the tempering furnace body, and the high-temperature resistant fiber is in contact with the bottom of the filter screen.

[0018] Compared with the prior art, the beneficial effect achieved by the present invention is: the present invention is designed to cooperate with the impurity cleaning mechanism and the prompt cleaning mechanism. If the filter is in a cleared state, the gas transmission flow is large at this time, so the external connecting pipe will be affected by the temperature transfer and then the gas between the connecting shell and the external connecting pipe will expand due to the heat. When the gas begins to expand, it will simultaneously drive the sealing block to move upward. During the upward movement, the sealing block will also simultaneously drive the prompt column to move upward. At this time, the staff can judge whether the filter is blocked by the rising of the prompt column. If the filter is blocked, the prompt column will no longer rise within the specified time, so that the blockage of the filter can be directly judged, which is convenient for the subsequent clearing of the filter.

[0019] Compared with the prior art, the beneficial effect achieved by the present invention is: through the design of the matching of the impurity cleaning mechanism and the prompt cleaning mechanism, the present invention will synchronously drive the arc-shaped rotating rod to rotate when the high-temperature resistant connecting roller rotates, so that the arc-shaped rotating rod can continuously contact and lift the bottom of the movable connecting plate. When the movable connecting plate is lifted, the sliding block will move synchronously. Then, when the arc-shaped rotating rod is quickly separated from the movable connecting plate, the movable connecting plate will drive the sliding block to reset, and collide with the tempering furnace body through its own weight, so as to effectively shake off and separate the impurities at the bottom of the filter screen, which is convenient for subsequent use.

[0020] Compared with the prior art, the beneficial effect achieved by the present invention is as follows: the present invention adopts the design of coordinating the impurity cleaning mechanism and the prompt cleaning mechanism. Since the high-temperature resistant connecting roller will also synchronously drive the movable card plate to rotate during the rotation process, and the general state of the movable card plate is: it falls on the lowest end of the sliding groove by its own weight, so when the high-temperature resistant connecting roller drives one side wall of the sliding groove to contact the movable card plate, the movable card plate will be driven to rotate by force. When one side wall of the bottom of the sliding groove rotates to the top state of the high-temperature resistant connecting roller and tilts, the movable card plate will synchronously drive the cleaning self-cleaning plate to start sliding downward by its own weight. In the process, the cleaning self-cleaning plate will scrape and comb the high-temperature resistant fibers through the internal scraping groove, thereby facilitating the long-term use of the high-temperature resistant fibers.

[0021] Compared with the prior art, the beneficial effect achieved by the present invention is: through the design of the impurity cleaning mechanism, the present invention can drive the counterweight rod to rotate when the high-temperature resistant connecting roller rotates. When the counterweight rod is in an upward state, it will fall down due to its own weight and collide with the high-temperature resistant connecting roller to increase the vibration sense, thereby avoiding the situation where the cleaning self-cleaning plate cannot fall due to insufficient cleaning force caused by the internal entanglement of the high-temperature resistant fibers when combing the high-temperature resistant fibers, thereby ensuring the use effect.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-9 The present invention provides a technical solution: a continuous stress relief tempering furnace circulation device, comprising a tempering furnace body 1, a telescopic cylinder 2 fixedly connected to the rear side of the tempering furnace body 1, an impurity cleaning mechanism 3 provided inside the tempering furnace body 1, a shell 5 fixedly installed on the outer side of the tempering furnace body 1, an external connecting pipe 6 fixedly installed on the outer side of the shell 5, and a prompt cleaning mechanism 4 provided on the top of the external connecting pipe 6;

[0035] The impurity cleaning mechanism 3 includes a sliding screw 301, which is slidably connected to the inside of the telescopic cylinder 2. The sliding screw 301 is rotatably connected to a rotating connecting rod 302. The outer side of the rotating connecting rod 302 is fixedly connected to a gear 303. A rack plate 304 is provided at the bottom of the gear 303, so that the gear 303 drives the rotating connecting rod 302 to rotate during the rotation process.

[0036] The rotating connecting rod 302 is fixedly connected to the outside of a high-temperature resistant connecting roller 305, and the high-temperature resistant connecting roller 305 is fixedly connected to the outside of a high-temperature resistant fiber 306. A curved rotating rod 307 is fixedly connected to one side of the high-temperature resistant connecting roller 305. A movable connecting plate 308 is provided on the top of the high-temperature resistant fiber 306. A filter screen 309 is embedded in the movable connecting plate 308. Four sliding blocks 310 are fixedly connected to the outside of the movable connecting plate 308, so that the movable connecting plate 308 can slide quickly.

[0037] Two movable clamping plates 311 are provided inside the high-temperature resistant connecting roller 305. One side of each movable clamping plate 311 is fixedly connected to a cleaning self-cleaning plate 312. Two counterweight rods 313 are provided inside the high-temperature resistant connecting roller 305, so that the movable clamping plates 311 drive the cleaning self-cleaning plates 312 to rotate.

[0038] The prompt cleaning mechanism 4 includes a connecting shell 401 , which is fixedly connected to the top of the external connecting tube 6 . A sealing block 402 is slidably connected inside the connecting shell 401 , and a prompt column 403 is fixedly connected to the top of the sealing block 402 .

[0039] The sliding screw rod 301 extends into the interior of the tempering furnace body 1 , and the outer surface of the sliding screw rod 301 contacts the interior of the tempering furnace body 1 .

[0040] Four connecting grooves are formed inside the tempering furnace body 1 , and the four sliding blocks 310 extend into the four connecting grooves respectively and are slidably connected to the four connecting grooves.

[0041] One side of the rack plate 304 is fixedly connected to a side wall of the inner cavity of the tempering furnace body 1 , and the gear 303 is meshed with the rack plate 304 .

[0042] Two sliding grooves are provided on one side of the high temperature resistant connecting roller 305 , and two movable clamping plates 311 are slidably connected to the inside of the two sliding grooves respectively.

[0043] A plurality of scraping grooves are provided inside the self-cleaning plate 312 , and the number of the scraping grooves corresponds to the number of the high-temperature resistant fibers 306 .

[0044] Two arc-shaped grooves are provided inside the high-temperature resistant connecting roller 305 , and the two counterweight rods 313 are slidably connected to the inside of the two arc-shaped grooves respectively.

[0045] A support frame is fixedly installed at the bottom of the tempering furnace body 1, and the high temperature resistant fiber 306 is in contact with the bottom of the filter screen 309.

[0046] During use, when the material needs to be tempered, the staff puts the material into the tempering furnace body 1, and then opens the tempering furnace body 1. At this time, since the tempering furnace body 1 is in a tempering working state, when the internal temperature begins to rise, the gas will be conducted to the inside of the external through-tube 6 through the shell 5, and then the recovered gas will be recovered through the equipment connected to the external through-tube 6 for waste heat recovery or gas purification.

[0047] In the above process, since it takes time for the temperature inside the tempering furnace body 1 to rise, it is convenient to carry out subsequent work when the tempering furnace body 1 completes the heating within the specified time: when heating within the specified time, the gas inside the tempering furnace body 1 will be discharged through the filter 309 and the external through-tube 6. If the filter 309 is in a cleared state at this time, due to the large flow rate of gas transmission, the external through-tube 6 will be subjected to temperature transfer and then cause the gas between the connecting shell 401 and the external through-tube 6 to expand due to heat. When the gas begins to expand, it will simultaneously drive the sealing block 402 to move upward. In the process of moving upward, the sealing block 402 will simultaneously drive the prompt column 403 to move upward. At this time, the staff can judge whether the filter 309 is blocked by the rising of the prompt column 403. If the filter 309 is blocked, the prompt column 403 will not rise within the specified time, so that the blockage of the filter 309 can be directly judged, which is convenient for the subsequent clearing of the filter 309.

[0048] When the staff finds that the filter screen 309 is blocked, the telescopic cylinder 2 is opened at this time. The operation of the telescopic cylinder 2 will drive the sliding screw rod 301 to telescopically move. The sliding screw rod 301 will synchronously drive the rotating connecting rod 302 to move during the movement. The rotating connecting rod 302 will synchronously drive the gear 303 to move during the movement. Since the gear 303 is meshed with the rack plate 304, the gear 303 will start to rotate. During the rotation of the gear 303, the rotating connecting rod 302 and the high-temperature resistant connecting roller 305 will be rotated. During the rotation of the high-temperature resistant connecting roller 305, the high-temperature resistant fiber 306 will be synchronously driven to rotate. During the rotation, the high-temperature resistant fiber 306 will synchronously clean the impurities at the bottom of the filter screen 309, so as to facilitate the self-cleaning and dredging of the filter screen 309.

[0049] During the above working process, when the high temperature resistant connecting roller 305 rotates, it will also synchronously drive the arc-shaped rotating rod 307 to rotate, so that the arc-shaped rotating rod 307 can continuously contact and lift the bottom of the movable connecting plate 308. When the movable connecting plate 308 is lifted, the sliding block 310 will move synchronously. Then, when the arc-shaped rotating rod 307 is quickly separated from the movable connecting plate 308, the movable connecting plate 308 will drive the sliding block 310 to reset, and collide with the tempering furnace body 1 through its own weight, so as to effectively shake off and separate the impurities at the bottom of the filter screen 309, which is convenient for subsequent use.

[0050] When the cam 311 is in the state of being moved downwards, the self-cleaning plate 312 of the cleaning machine 310 is moved downwards, and ...

[0051] When the high temperature resistant connecting roller 305 rotates, it will also drive the counterweight rod 313 to rotate. When the counterweight rod 313 is in an upward state, it will fall down due to its own weight and collide with the high temperature resistant connecting roller 305 to increase the vibration sense, thereby avoiding the situation where the cleaning self-cleaning plate 312 cannot fall due to insufficient cleaning force caused by the internal entanglement of the high temperature resistant fibers 306 when combing the high temperature resistant fibers 306, thereby ensuring the use effect.
