Description

Technical Field

[0001] The invention belongs to the technical field of cold-rolled stainless steel, in particular to an automatic cold-rolling device for cold-rolled stainless steel. Background Art

[0002] Cold-rolled stainless steel refers to the process of rolling stainless steel plates and strips through a rolling mill at room temperature to cause them to undergo plastic deformation, thereby obtaining stainless steel products of specific size, shape and performance. Compared with hot rolling, the metal material is not heated during the cold rolling process, or the heating temperature is low, far below the recrystallization temperature.

[0003] For example, the invention with publication number CN110369508B relates to the field of stainless steel strips, specifically, a stainless steel strip cold rolling device, including a base, a loading coil, a receiving coil, a power mechanism, a cold rolling mechanism, a guide mechanism, a foreign matter removal mechanism, and a cooling mechanism. The loading coil and the receiving coil are respectively fixed on both sides of the upper end of the base, the cold rolling mechanism is fixed in the middle of the upper end of the base, and the cold rolling mechanism is driven by a power mechanism, the power mechanism is fixedly connected to the upper end of the base, and the guide mechanism and the foreign matter removal mechanism are both arranged on the right side of the cold rolling mechanism. By setting up a guide mechanism and a foreign matter removal mechanism, the steel strip to be processed can be positioned by using the guide wheels and wheel grooves in the guide mechanism to prevent the steel strip from shifting during the processing process. By using the brush of the foreign matter removal mechanism, the foreign matter on the surface of the steel strip can be removed by the brush when the steel strip passes through the receiving roller, thereby avoiding scratches and grooves on the surface of the steel strip due to foreign matter when the steel strip is cold rolled;

[0004] When the above device is in use, the cold rolling efficiency and quality of stainless steel are improved by the cooperation between structures such as the positioning component and the foreign matter cleaning component. However, when the stainless steel coil is cold-rolled and enters the winding process, since the line speed is proportional to the radius of the reel, when the speed of the winding motor remains unchanged and the diameter of the reel gradually increases, the line speed of the steel strip will gradually increase, which will cause the tension on the steel strip to increase, and may cause the steel strip to be over-stretched. At the same time, if the tension is not appropriate, as the reel becomes larger, the steel strip may become loose or partially too tight, resulting in uneven winding, tower-shaped, loose coils and other problems, which in turn affects the appearance quality and subsequent use of the product. Therefore, an automatic cold rolling device for cold-rolled stainless steel is proposed to solve the problems raised in the background technology. Summary of the invention

Subsequently, through the design of the spring sheet, after the two convex rods are disconnected from the first arc groove, the limit plate will be reset under the action of the tension of the spring sheet, thereby causing the support block to drive the guide roller to move upward under the action of external force. Finally, through the reverse rotation of the threaded rod, the convex rod is moved downward under the action of external force and re-engaged in the first arc groove, thereby facilitating the resetting of the adjusting device and facilitating the next use of the device.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, the present invention provides a cold-rolled stainless steel automatic cold rolling device, comprising a cold rolling mill 1, and further comprising:

[0035] A support frame 2, the support frame 2 is symmetrically arranged on both sides of one end of the cold rolling mill 1, and a winding assembly 3 is arranged at the top of the support frame 2;

[0036] An adjusting device 4, the adjusting device 4 is located inside the supporting frame 2;

[0037] A rotating assembly 5, the rotating assembly 5 is movably connected to the inside of the supporting frame 2, and one end of the rotating assembly 5 away from the adjusting device 4 is meshedly connected with a gear set 6;

[0038] Working rolls 8, a plurality of groups of working rolls 8 are arranged inside the cold rolling mill 1;

[0039] The winding assembly 3 includes a motor 31, the output shaft end of the motor 31 is fixedly connected to a rotating shaft 32, and a winding drum 33 is clamped in the middle of the outer wall of the rotating shaft 32;

[0040] The adjusting device 4 comprises two guide rollers 41 , both ends of which are movably connected with support blocks 42 , and the interior of the support frame 2 is movably connected with a limit plate 43 , and a surface of the limit plate 43 is provided with an inclined groove 44 .

[0041] The above scheme is adopted: the stainless steel coil is continuously wound onto the winding drum 33 during the winding process, and its tension will also change with the increase in the diameter of the winding drum 33. At this time, the support block 42 is driven to move gradually downward by the movement of the limit plate 43, so that the support block 42 drives the two guide rollers 41 to move synchronously, and then the two guide rollers 41 pull the stainless steel coil downward as the diameter of the winding drum 33 continues to increase, thereby adjusting the tension change generated, and ensuring that the stainless steel coil is stably, evenly and tightly wound onto the winding drum 33.

[0042] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a reset assembly 7 is provided inside the limit plate 43, and the reset assembly 7 includes a rotating cylinder 71, and a second arc groove 72 is formed in an annular manner on the surface of the rotating cylinder 71, and a slide groove 74 is formed at the top of the rotating cylinder 71. A threaded rod 73 is threadedly connected to the top of the limit plate 43, and the top of the threaded rod 73 passes through the outer wall of the support frame 2 and extends to the outside of the support frame 2. The bottom end of the threaded rod 73 moves inside the slide groove 74. The rotating assembly 5 includes a rotating rod 51, and a first arc groove 52 is formed in an annular manner on the outer wall of one end of the rotating rod 51, and a bevel gear 53 is fixedly connected to the other end of the rotating rod 51.

[0043] The above scheme is adopted: when the rotating drum 71 rotates, the second protrusion on the protruding rod 45 slides upward along the trajectory of the second arc groove 72, thereby driving the first protrusion at the bottom of the protruding rod 45 to move upward, thereby disengaging from the inside of the first arc groove 52. Subsequently, through the design of the spring piece 46, the two protruding rods 45 are disconnected from the first arc groove 52, and the limit plate 43 will be reset under the action of the pulling force of the spring piece 46, thereby causing the support block 42 to drive the guide roller 41 to move upward under the action of external force. Finally, through the reverse rotation of the threaded rod 73, the protruding rod 45 is moved downward under the action of external force and re-stuck in the first arc groove 52, thereby facilitating the resetting of the adjustment device 4 and facilitating the next use of the device.

[0044] like Figure 3 , Figure 4 and Figure 7As shown, the winding drum 33 and the guide roller 41 are both located between the two support frames 2, and round blocks are provided on the opposite sides of the two support blocks 42, which are movably clamped in the inside of the inclined groove 44, and the limiting plate 43 passes through the outer wall of the support frame 2 and extends to the inside of the cold rolling mill 1. The bottom of the limiting plate 43 is movably connected with a protruding rod 45, and an unwinding assembly is provided at the end of the cold rolling mill 1 away from the support frame 2. A second protruding block is provided on the side of the protruding rod 45 close to the reset assembly 7, and the second protruding block is movably clamped in the inside of the second arc groove 72. The inner wall of the limiting plate 43 is provided with a square groove for limiting the protruding rod 45 in the vertical direction.

[0045] The above scheme is adopted: a square groove is opened on the inner wall of the limit plate 43, and its function is that when the protruding rod 45 moves toward the rotating shaft 32 along the trajectory of the first arc groove 52, the protruding rod 45 will be limited in the vertical direction through the square groove, thereby pulling the limiting plate 43 to move together. When the rotating drum 71 rotates, the protruding rod 45 will also be limited in the vertical direction through the square groove, so that the second protrusion can only move up and down along the trajectory of the second arc groove 72, thereby ensuring the normal operation of the device.

[0046] like Figure 5 and Figure 6 As shown, a first protrusion movably connected to the inside of the first arc groove 52 is provided at the bottom of the protruding rod 45, a second limiting groove 48 for limiting the limiting plate 43 in the horizontal direction is provided in the middle of the inner cavity of the support frame 2, and a spring plate 46 is fixedly connected to the end of the limiting plate 43 away from the gear set 6, and the limiting plate 43 is elastically connected to the cold rolling mill 1 through the spring plate 46. A first limiting groove 47 matching with the support block 42 is provided on the side wall of the support frame 2, and the gear set 6 includes two spur gears and a bevel gear, and the helical gear 53 is meshed and connected with the bevel gear in the gear set 6, and the two ends of the rotating shaft 32 are respectively fixedly connected to the spur gears at the top of the two gear sets 6.

[0047] Adopting the above scheme: by opening the second limiting groove 48, its function is, specifically by Figure 5 It can be seen that the second limit groove 48 is compatible with the limit plate 43. At the same time, the second limit groove 48 also limits the limit plate 43 in the horizontal direction, so that when the rotating rod 51 rotates, the protruding rod 45 can only drive the limit plate 43 to move horizontally and linearly along the trajectory of the first arc groove 52, thereby ensuring the normal operation of the device.

[0048] The working principle and use process of the present invention are as follows: first, the operator feeds the cold-rolled stainless steel coil into the cold rolling mill 1 through the unwinding assembly, and then, a plurality of groups of working rollers 8 provided in the cold rolling mill 1 contact the stainless steel coil and rotate at high speed driven by a power source, thereby applying pressure to the stainless steel coil to cause plastic deformation. When the stainless steel coil is rolled, it passes between two guide rollers 41 and is operated by the motor 31, so that the rotating shaft 32 drives the winding drum 33 outside it to rotate, so that the stainless steel coil after rolling is wound onto the winding drum 33;

[0049] When the rotating shaft 32 rotates, the meshing connection between the gear set 6 and the bevel gear 53 drives the rotating rod 51 to rotate, thereby causing the first protrusion at the bottom of the protruding rod 45 to slide along the trajectory of the first arc groove 52. Since the second limiting groove 48 limits the limiting plate 43 in the horizontal direction, when the rotating rod 51 rotates, the protruding rod 45 can only drive the limiting plate 43 to move slowly toward the direction of the winding drum 33 along the trajectory of the first arc groove 52. When the limiting plate 43 moves, it will drive the round block on the support frame 2 to slide along the trajectory of the oblique groove 44. At this time, since the second limiting groove 48 limits the support block 42 in the vertical direction, the support block 42 can only drive the two guide rollers 41 to move downward together.

[0050] As the stainless steel coil is continuously wound onto the winding drum 33, the diameter of the winding drum 33 becomes larger and larger. At the same time, the tension of the stainless steel coil will also change as the diameter of the winding drum 33 increases. At this time, the two guide rollers 41 pull the stainless steel coil downward as the winding drum 33 continues to increase, thereby adjusting the tension change, which helps to maintain the tension of the stainless steel coil in a reasonable range during the winding process, thereby ensuring that the stainless steel coil is stably, evenly and tightly wound onto the winding drum 33, thereby improving the overall working efficiency and quality of the cold rolling device.

[0051] When the winding work is completed, the first protrusion at the bottom end of the protruding rod 45 also abuts against the inner wall of the first arc groove 52 near one end of the winding assembly 3. Subsequently, the operator rotates the threaded rod 73, thereby driving the rotating drum 71 to rotate through the sliding groove 74, so that the second protrusion on one side of the protruding rod 45 slides along the trajectory of the second arc groove 72. While the rotating drum 71 slides, the square groove inside the limiting plate 43 limits the protruding rod 45 in the vertical direction. Therefore, the second protrusion can only drive the protruding rod 45 to move upward. After the protruding rod 45 moves upward, the first protrusion at its bottom disengages from the inside of the first arc groove 52, thereby The first arc groove 52 releases the limit on the first protrusion. When the two protrusions 45 are out of the first arc groove 52, the limit plate 43 will be reset under the action of the pulling force of the spring piece 46, thereby driving the protrusion 45 to move in the direction away from the winding component 3. When the limit plate 43 drives the protrusion 45 to be completely reset, the operator rotates the rotating drum 71 in the opposite direction, so that the second protrusion drives the protrusion 45 to move downward along the trajectory of the second arc groove 72, and then drives the first protrusion to be re-stuck in the first arc groove 52, so as to facilitate the operator's next use, thereby improving the overall convenience and practicality of the device.
