Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment technology, specifically to a heat treatment device for metal normalizing. Background Technology
[0002] Mining circular link chains are important components that connect mining equipment and ore. Normalizing heat treatment can enhance their strength and toughness, preventing them from breaking due to excessive stress during use.
[0003] In traditional processes, the normalizing heat treatment of round chains is usually completed in a separate heat treatment device. This process involves heating the round chain to a certain temperature, holding it for a period of time, and then cooling it. However, after the heat treatment is completed, a large amount of debris often remains on the surface of the round chain. This debris not only affects the surface quality of the round chain, but also has an adverse effect on its subsequent processing and use.
[0004] To address this issue, traditional processes typically employ a separate cleaning step, involving manual or mechanical cleaning of the round chain surface. However, this method is not only time-consuming and labor-intensive, increasing production costs, but also prone to defects such as scratches and pits on the round chain surface due to improper cleaning, further reducing its surface quality and performance.

[0010] The chain fixed wheel is used to drive the round chain to move. The first fixed plate is equipped with a sprocket drive device, which is used to drive the two sprocket shafts to rotate synchronously.
[0011] Both wire brush wheels are rotatably connected to the corresponding U-shaped frames. The wire brush wheels are used to clean debris from the surface of the round chain. Both U-shaped frames are fixedly connected inside the movable frame.
[0012] Preferably, the lower end of the movable frame is fixedly connected to a sliding plate, the C-shaped slide rail is fixedly connected to the vertical plate of the support frame, the wave-shaped slide rail is opened on the outer surface of the C-shaped slide rail, and the lower surface of the sliding plate is rotatably connected to a pulley.
[0013] Preferably, the pulley is slidably connected to the inner wall of the wave groove, and the slide plate is slidably connected to the C-shaped groove rail. The width of the slide plate is narrower than the width of the inner groove of the C-shaped groove rail, and the slide plate can move back and forth and left and right within the C-shaped groove rail.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a heat treatment device for metal normalizing, which has the following beneficial effects:
[0019] 1. This heat treatment equipment for metal normalizing uses a gear and rack on the lower side to mesh, which allows the lower gear to drive the upper gear to rotate inward together. At this time, the two gears drive two wire brush wheels to rotate outward together. This causes the circular chain between the two wire brush wheels to be brushed off and fall into the debris collection box. At this time, the high-temperature treated debris on the circular chain can be effectively cleaned. This process not only realizes the normalizing heat treatment of the circular chain, but also simultaneously cleans the surface debris. This avoids the problem of needing to heat and clean separately in the traditional method, which is not only time-consuming and labor-intensive, but also leads to poor surface quality of the circular chain due to improper handling.
[0020] 2. This heat treatment equipment for metal normalizing, through the corrugated chute and pulley set in the chain normalizing cleaning component, allows the round chain to be continuously shaken when the wire brush wheel cleans it. This not only allows the wire brush wheel to clean the debris on the round chain more evenly, but also allows the impurities that fall on the round chain below after cleaning to be shaken into the debris collection box. Shaking off the impurities further ensures the surface quality of the round chain, reduces problems that may occur in subsequent processing, and lays a good foundation for the next process.

[0029] Please see Figure 1-3 This utility model provides a new technical solution: a heat treatment device for metal normalizing, including a support frame 1, a heat insulation cover on the support frame 1, and a chain normalizing cleaning assembly on the support frame 1. The chain normalizing cleaning assembly is used to clean the debris on the surface of the round chain. The chain normalizing cleaning assembly includes a first fixed plate 2, a C-shaped slide rail 4, a movable frame 6, a U-shaped frame 7, a wire brush wheel 8, a rack 10, an electromagnetic heating ring 12, a push rod 13, a debris collection box 14, and a corrugated slide 15.
[0030] The first fixing plate 2 in the chain normalizing cleaning assembly is fixedly connected to the vertical plate of the support frame 1. Two sprocket shafts 3 are rotatably connected to the first fixing plate 2, and chain fixing wheels 18 are fixedly sleeved on each sprocket shaft 3.
[0031] The chain fixed wheel 18 is used to drive the round chain to move. The first fixed plate 2 is provided with a sprocket drive device 17, which is used to drive the two sprocket shafts 3 to rotate synchronously.
[0032] Both wire brush wheels 8 are rotatably connected to the corresponding U-shaped frame 7. The wire brush wheels 8 are used to clean the debris on the surface of the round chain. Both U-shaped frames 7 are fixedly connected inside the movable frame 6.
[0033] Furthermore, a sliding plate 5 is fixedly connected to the lower end of the movable frame 6, a C-shaped slide rail 4 is fixedly connected to the vertical plate of the support frame 1, a wave-shaped slide rail 15 is opened on the outer surface of the C-shaped slide rail 4, and a pulley 16 is rotatably connected to the lower surface of the sliding plate 5.
[0034] Furthermore, the pulley 16 is slidably connected to the inner wall of the wave groove 15, and the slide plate 5 is slidably connected to the C-shaped groove rail 4. The width of the slide plate 5 is narrower than the inner groove width of the C-shaped groove rail 4, and the slide plate 5 can move back and forth and left and right within the C-shaped groove rail 4.
[0035] Furthermore, a gear 9 is fixedly sleeved on the outer surface of the rotating shaft of the wire brush wheel 8. The two gears 9 are meshed and connected. The rack 10 is fixedly connected to the C-shaped slide rail 4, and the lower gear 9 is meshed and connected to the rack 10.
[0036] Furthermore, a push rod fixing plate 11 is fixedly connected to the upper end of the C-shaped slide rail 4, and an electromagnetic heating ring 12 is fixedly installed on the upper surface of the push rod fixing plate 11. The electromagnetic heating ring 12 is used to heat the round chain to the temperature required for normalizing, and the push rod 13 is fixedly installed on the push rod fixing plate 11.
[0037] Furthermore, the output end of the push rod 13 is rotatably connected to the moving frame 6, and the debris collection box 14 is set on the bottom plate of the support frame 1. The debris collection box 14 is used to collect the debris cleaned off the round chain.
[0038] Furthermore, in use, the round chain requiring normalizing heat treatment is passed through the electromagnetic heating ring 12, and then sequentially passed between the two wire brush wheels 8, so that the round chain is positioned on the two chain fixing wheels 18. The round chain is then passed out of the support frame 1 to align with the chain fixing wheels 18 of the next process. The sprocket drive device 17 is then activated, which drives the chain fixing wheels 18 on the two sprocket shafts 3 to rotate. The rotation of the two chain fixing wheels 18 moves the round chain on them. After covering with an insulation cover, the electromagnetic heating ring 12 is activated, heating the round chain to a suitable normalizing temperature. Then, the push rod 13 is activated, causing the moving frame 6 and the slide plate 5 to move forward. As the slide plate 5 moves, it moves along the wave groove 15 under the force of the pulley 16 on it. The skateboard 5 moves along a trajectory, allowing it to swing and move simultaneously. As the skateboard 5 moves the wire brush wheel 8 via the moving frame 6 and the U-shaped frame 7, the meshing of the lower gear 9 with the rack 10 causes the lower gear 9 to rotate inward along with the upper gear 9. At this time, the two gears 9 can drive the two wire brush wheels 8 to rotate outward together. This allows the circular chain between the two wire brush wheels 8 to be brushed off and fall into the debris collection box 14. The high-temperature treated debris on the circular chain can be effectively cleaned. This process not only achieves the positive heat treatment of the circular chain but also simultaneously cleans the surface debris. This avoids the need for separate heating and cleaning in the traditional method, which is not only time-consuming and labor-intensive but also leads to poor surface quality of the circular chain due to improper handling.
[0039] Furthermore, by setting the wave groove 15 and pulley 16 in the chain normalizing cleaning assembly, the round chain can be continuously shaken when the wire brush wheel 8 cleans the round chain. This not only allows the wire brush wheel 8 to clean the debris on the round chain more evenly, but also allows the impurities that fall on the round chain below after cleaning to be shaken into the debris collection box 14. Shaking off the impurities further ensures the surface quality of the round chain, reduces problems that may occur in subsequent processing, and lays a good foundation for the next process.
[0040] Working principle: During use, the round chain requiring normalizing heat treatment is passed through the electromagnetic heating ring 12, then sequentially between two wire brush wheels 8, so that the round chain is positioned on the two chain fixing wheels 18. The round chain is then passed out of the support frame 1 and matched with the chain fixing wheels 18 for the next process. The sprocket drive device 17 is then activated, which drives the chain fixing wheels 18 on the two sprocket shafts 3 to rotate. The rotation of the two chain fixing wheels 18 moves the round chain on them. After covering with an insulation cover, the electromagnetic heating ring 12 is activated, heating the round chain to the appropriate normalizing temperature. Then, the push rod 13 is activated, which drives the chain to move... The moving frame 6 and the slide plate 5 can move forward. When the slide plate 5 moves, it can move along the trajectory of the wave groove 15 under the force of the pulley 16 on it. This allows the slide plate 5 to swing and move at the same time. When the slide plate 5 drives the wire brush wheel 8 to move through the moving frame 6 and the U-shaped frame 7, the meshing of the lower gear 9 and the rack 10 allows the lower gear 9 to drive the upper gear 9 to rotate inward together. At this time, the two gears 9 can drive the two wire brush wheels 8 to rotate outward together. This allows the round chain between the two wire brush wheels 8 to be rotated and brushed off, falling into the debris collection box 14. At this time, the debris on the round chain after high temperature treatment can be effectively cleaned.
