DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] like Figure 1 - Fig. 9 A tempering device for heat treatment of steel shown in the figure comprises a tempering furnace 1, wherein a chassis 2 is movably arranged inside the tempering furnace 1, a protruding disk 3 is arranged at the center of the top of the chassis 2, six limiting mechanisms 4 are evenly arranged on the surface of the protruding disk 3, the limiting mechanism 4 comprises a clamping mechanism 9 and an auxiliary rotating mechanism 18, a first fixed plate 5 is arranged below the clamping mechanism 9, a second fixed plate 6 is arranged below the auxiliary rotating mechanism 18, the first fixed plate 5 corresponds to the second fixed plate 6 in parallel, the first fixed plate 5 and the second fixed plate 6 are both fixedly connected to the protruding disk 3, the other ends of the first fixed plate 5 and the second fixed plate 6 are fixedly connected to a connecting plate 7, the auxiliary rotating mechanism 18 is located between the first fixed plate 5 and the second fixed plate 6, the auxiliary rotating mechanism 18 is matched with the clamping mechanism 9, a lifting block 24 is movably arranged inside the chassis 2, the lifting block 24 is matched with the auxiliary rotating mechanism 18, six transmission mechanisms 27 are evenly arranged on the side of the lifting block 24, and the transmission mechanism 27 corresponds to the limiting mechanism 4.

[0027] Two T-shaped slots 10 are symmetrically arranged on the upper surface of the first fixed plate 5, and the clamping mechanism 9 includes two translation blocks 11, and a T-shaped slider is arranged at the bottom of the translation block 11, and the two T-shaped sliders are respectively slidably installed in the two T-shaped slots 10, and a turntable 13 is rotatably installed between the two translation blocks 11, and two protruding rods 14 are symmetrically installed on the surface of the turntable 13, and a connecting rod 15 is rotatably installed at the bottom of the protruding rod 14 through a rotating shaft, and a matching plate 12 is arranged in the middle of the translation block 11, and the other end of the connecting rod 15 is installed at the bottom of the matching plate 12 through a rotating shaft. Since the two ends of the connecting rod 15 are respectively connected to the protruding rod 14 and the matching plate 12 through the rotating shaft, when the turntable 13 rotates, under the action of the connecting rod 15, the protruding rod 14 can push or pull the matching plate 12, thereby controlling the spacing between the two translation blocks 11, and realizing the relaxation or clamping of the steel coil.

[0028] Clamping columns 16 are fixedly arranged on the adjacent surfaces of the two translation blocks 11, and side columns 17 are arranged above the translation blocks 11. The side columns 17 are fixedly connected to the clamping columns 16. The clamping columns 16 can clamp the steel coil to ensure the stability of the steel coil on its surface when the chassis 2 is hung.

[0029] The auxiliary rotating mechanism 18 includes a first gear 21, a rotating shaft is provided through the center of the first gear 21, and the top of the rotating shaft is connected to the rotating disk 13, and the bottom of the rotating shaft is rotatably mounted on the surface of the second fixed plate 6. Extending rods 19 are movably provided on both sides of the first gear 21, and a first rack surface 20 is provided on the surface of one of the extending rods 19, and the first rack surface 20 is meshed with the first gear 21. When the extending rod 19 moves toward the outside of the protruding disk 3, the first rack surface 20 can drive the first gear 21 to rotate. Since the first gear 21 is connected to the rotating disk 13 through the rotating shaft, the rotating disk 13 rotates forward at this time, and the protruding rod 14 gradually tends to be parallel to the translation block 11. The protruding rod 14 pulls the translation block 11 toward the middle of the first fixed plate 5 through the connecting rod 15, and the distance between the two translation blocks 11 gradually decreases. Therefore, the clamping column 16 can clamp the steel coil to ensure the stability of the steel coil on its surface when the chassis 2 is hung. Similarly, when the protruding rod 19 moves toward the inside of the protruding disk 3, the turntable 13 rotates in the opposite direction, and the protruding rod 14 gradually tends to be vertical with the translation block 11. The protruding rod 14 pushes the translation block 11 to the two ends of the first fixed plate 5 through the connecting rod 15, and the distance between the two translation blocks 11 gradually increases, so that the clamping column 16 will not clamp the steel coil. A certain space is reserved between the clamping column 16 and the steel coil, which can improve the tempering quality of the steel coil. The two protruding rods 19 both pass through the protruding disk 3, and the end faces of the two protruding rods 19 inside the protruding disk 3 are fixedly connected with a pushing block 22. The pushing block 22 can operate the two protruding rods 19 at the same time to ensure that the two protruding rods 19 can run synchronously.

[0030] The end face of the top of the lifting block 24 is set as an inclined surface, and the bottom of the pushing block 22 is set as an inclined plate corresponding to the inclined surface. When the lifting block 24 moves upward, the inclined surface of its end has a certain extrusion force on the inclined plate, and the pushing block 22 can be pushed to the outside of the protruding disk 3. A lifting column 25 is arranged above the protruding disk 3. The bottom of the lifting column 25 is connected to the lifting block 24 through a connecting rod, and a lifting ring 26 is arranged at the middle end of the top of the lifting column 25. With the cooperation of the lifting ring 26, the lifting column 25 and the lifting block 24, the staff can use the lifting mechanism to hang the chassis 2, so that when the device is hung, the clamping column 16 can clamp the steel coil to ensure the stability of the steel coil. The lifting mechanism is an existing mature technology and will not be elaborated in detail here.

[0031] When the staff suspends the lifting column 25, the lifting block 24 moves upward. At this time, with the cooperation between the clamping mechanism 9, the auxiliary rotating mechanism 18, and the transmission mechanism 27, the clamping column 16 can clamp the steel coil to ensure the stability of the steel coil on its surface when the chassis 2 is suspended. When the chassis 2 is placed in the tempering furnace 1, the lifting block 24 descends under the action of gravity. At this time, the clamping force of the clamping column 16 on the steel coil is reduced, and a certain space is reserved between the clamping column 16 and the steel coil, which can improve the tempering quality of the steel coil.

[0032] The transmission mechanism 27 includes a contraction groove 28, a cross bar 29 is movably provided inside the contraction groove 28, a second rack surface 30 is provided below the contraction groove 28, a second gear 31 is rotatably provided below the contraction groove 28, and the second gear 31 is meshed with the second rack surface 30, an L-shaped rod 32 matching the cross bar 29 is fixedly installed on the surface of the lifting block 24, a splitting groove 35 is provided in the middle of the cross bar 29, the L-shaped rod 32 is located below the splitting groove 35, a third rack surface 33 is provided on the surface of the L-shaped rod 32, and the third rack surface 33 is meshed with the second gear 31, a slot 34 is provided above the contraction groove 28, and the slot 34 is located directly above the L-shaped rod 32, and the cross bar 29 is in the contraction groove. The outer end surface of 28 is close to the bottom of the pushing block 22. When the lifting block 24 is lifted upward, the L-shaped rod 32 moves upward, and the third rack surface 33 on its surface can drive the second gear 31 to rotate. At this time, under the action of the second rack surface 30, the cross bar 29 can be recovered to the inside of the contraction groove 28. When the lifting block 24 descends under the action of gravity, the L-shaped rod 32 moves downward, and the third rack surface 33 on its surface can drive the second gear 31 to rotate. At this time, under the action of the second rack surface 30, the cross bar 29 extends outward from the contraction groove 28, and the end surface of the cross bar 29 can push the pushing block 22 toward the center of the protruding disk 3, so that the extending rod 19 can move toward the inside of the protruding disk 3.

[0033] A placement frame 8 is fixedly installed at the middle end of the top of the first fixed plate 5, and a turntable 13 is arranged inside the placement frame 8. The steel coil can be placed on the surface of the placement frame 8. The placement frame 8 supports the steel coil and protects the clamping mechanism 9.

[0034] A side plate 23 is provided on the outer surface of the extension rod 19 , and the side plate 23 is slidably mounted on the side surface of the second fixed plate 6 , and the side plate 23 has the function of limiting and guiding the extension rod 19 .

[0035] Working principle: first, place the steel coil on the surface of the placement frame 8, and then when the staff hangs the lifting column 25, the lifting block 24 moves upward, and the L-shaped rod 32 moves upward. The third rack surface 33 on its surface can drive the second gear 31 to rotate. At this time, under the action of the second rack surface 30, the cross bar 29 can be recovered to the inside of the contraction groove 28. At the same time, the inclined surface of the end of the lifting block 24 has a certain extrusion force on the inclined plate, which can push the push block 22 to the outside of the protruding disk 3, and the extended rod 19 can be pushed to the outside of the protruding disk 3. The first rack surface 20 can drive the first gear 21 to rotate. Since the first gear 21 is connected to the turntable 13 through the rotating shaft, the turntable 13 rotates forward at this time, and the protruding rod 14 gradually becomes parallel to the translation block 11. The protruding rod 14 pulls the translation block 11 to the middle of the first fixed plate 5 through the connecting rod 15, and the distance between the two translation blocks 11 gradually decreases, thereby clamping The column 16 can clamp the steel coil to ensure the stability of the steel coil on its surface when the chassis 2 is hung. Then, when the chassis 2 is placed in the tempering furnace 1, the lifting block 24 drops under the action of gravity, and the L-shaped rod 32 moves downward. The third rack surface 33 on its surface can drive the second gear 31 to rotate. At this time, under the action of the second rack surface 30, the cross bar 29 extends outward from the contraction groove 28, and the end surface of the cross bar 29 can push the pushing block 22 toward the center of the protruding disk 3. When the protruding rod 19 moves toward the inside of the protruding disk 3, the turntable 13 rotates in the opposite direction. The protruding rod 14 gradually becomes perpendicular to the translation block 11. The protruding rod 14 pushes the translation block 11 toward the two ends of the first fixed plate 5 through the connecting rod 15. The distance between the two translation blocks 11 gradually increases, so that the clamping column 16 will not clamp the steel coil. A certain space is reserved between the clamping column 16 and the steel coil, which can improve the tempering quality of the steel coil.
