Description

Technical Field

[0001] The utility model relates to the field of temper rolling of cold-rolled strip steel, and particularly to a temper rolling device for cold-rolled strip steel. Background Technique

[0002] Cold-rolled strip steel is a kind of strip steel and thin plate rolled by a cold rolling mill at normal temperature with hot-rolled strip steel and steel plates as raw materials. Because of its precise product size and uniform thickness, it is widely used in industrial departments such as machinery manufacturing, automobile manufacturing, locomotive vehicles, and building structures.

[0003] Generally, after the cold-pressed strip steel is uncoiled by an uncoiler, an uncoiling tension is applied through an uncoiling tension roller and then it enters the temper rolling area. In the temper rolling area, the strip steel passes between the upper and lower working rolls and undergoes plastic deformation under the action of the rolling force, so as to achieve the tempering effect.

[0004] The existing temper rolling device for cold-rolled strip steel generally applies pressure to the strip steel through the upper and lower working rolls to make it flat. It is found in use and observation that in the tempering process of this kind of tempering method, due to the residual sand and gravel impurities on the surface of the strip steel, scratches are easily generated on the surface of the strip steel during tempering, affecting the flatness and accuracy of the strip steel.

[0005] Therefore, a temper rolling device for cold-rolled strip steel is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems mentioned in the background technique.

When the cold-rolled strip steel moves to the bottom of the air extraction box, the air extraction box adsorbs the sand and gravel impurities on the surface of the cold-rolled strip steel. By pumping air into the air extraction pipes, the air extraction box adsorbs the sand and gravel impurities on the surface of the strip steel, reducing the situation that the sand and gravel impurities cause scratches on the surface of the strip steel during the tempering process.

[0008] Preferably, a plurality of connecting arms are fixedly connected to the outer side wall of the air extraction box; a roller is rotatably connected to the end of the connecting arm; a plurality of convex blocks are fixedly connected to the surface of the roller. By fixedly connecting the convex blocks to the surface of the roller, when the convex blocks roll, they strike the surface of the cold-rolled strip steel, which can better lift the sand and gravel impurities and facilitate the air extraction box to adsorb the sand and gravel impurities.

[0009] Preferably, a bottom plate is fixedly connected to the top of the second support frame; the bottom plates are symmetrically arranged; a plurality of brushes are fixedly connected to the inner side wall of the bottom plate.

[0010] Preferably, a fixing frame is fixedly connected to the inner side wall of the first support frame; an auxiliary wheel is rotatably connected to the inner side wall of the fixing frame. By rotatably connecting an auxiliary wheel to the inner side wall of the fixing frame, it is possible to reduce the situation where the cold-rolled strip steel sways left and right during the forward movement of the cold-rolled strip steel and the cold-rolled strip steel is damaged due to collision.

By slidably connecting an auxiliary block to the surface of the auxiliary wheel, it is possible to reduce the amplitude of the up and down movement of the cold-rolled strip steel and reduce the situation of bumping. By fixedly connecting a positioning frame to the end of the auxiliary block, opening a positioning hole in the positioning frame, and fixedly connecting a positioning block to the top of the fixing frame, it is possible to assist cold-rolled strip steels of different thicknesses to reduce the situation of bumping.

[0012] Preferably, rubber blocks are fixedly connected to the surface of the auxiliary block; the rubber blocks are symmetrically arranged. When the cold-rolled strip steel slides on the surface of the auxiliary wheel, the side of the strip steel contacts the rubber blocks. By fixedly connecting the rubber blocks to the surface of the auxiliary block, it is possible to reduce the deformation of the strip steel caused by excessive pressure on the strip steel during the conveying process of the cold-rolled strip steel.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] The following gives specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, a temper mill for cold-rolled strip steel according to an embodiment of the present utility model includes an operating table 1, and a first support frame 11 is fixedly connected to the top of the operating table 1; a plurality of air extraction pipes 12 are arranged through the middle of the first support frame 11; an air extraction box 13 is communicated with the bottom of the air extraction pipe 12; a second support frame 14 is fixedly connected to the top of the operating table 1; a plurality of motors 15 are fixedly connected to the outer side wall of the second support frame 14; a roll 16 is fixedly connected to the output end of the motor 15; a conveying frame 17 is fixedly connected to the top of the operating table 1. When tempering the cold-rolled strip steel, the cold-rolled strip steel is placed on the conveying frame 17. At this time, air is extracted into the air extraction pipe 12. Dust and iron filings and other impurities will adhere to the surface of the cold-rolled strip steel during the production and transportation process. When the cold-rolled strip steel moves to the bottom of the air extraction box 13, the air extraction box 13 adsorbs the grit impurities on the surface of the cold-rolled strip steel. By extracting air into the air extraction pipe 12, the air extraction box 13 adsorbs the grit impurities on the strip steel surface, reducing the situation that the grit impurities cause scratches on the strip steel surface during the tempering process.

[0026] As Figure 1 shown, a plurality of connecting arms 2 are fixedly connected to the outer side wall of the air extraction box 13; a roller 21 is rotatably connected to the end of the connecting arm 2; a plurality of bumps 22 are fixedly connected to the surface of the roller 21. During the forward movement of the cold-rolled strip steel, the bumps 22 roll on the surface of the cold-rolled strip steel. At this time, the bumps 22 contact the cold-rolled strip steel surface and strike the cold-rolled strip steel surface. When the cold-rolled strip steel is struck, the grit impurities adhering to its surface are knocked up, and then the dust is adsorbed through the air extraction box 13. By fixedly connecting the bumps 22 to the surface of the roller 21, the bumps 22 strike the cold-rolled strip steel surface when rolling, which can better knock up the dust and facilitate the air extraction box 13 to adsorb the grit impurities.

[0027] As Figure 3 shown, a bottom plate 3 is fixedly connected to the top of the second support frame 14; the bottom plate 3 is symmetrically arranged; a plurality of brushes 31 are fixedly connected to the inner side wall of the bottom plate 3. After the air extraction box 13 adsorbs the surface of the cold-rolled strip steel, the cold-rolled strip steel moves forward, and then the motor 15 is started. The motor 15 drives the roll 16 fixedly connected to its output end to rotate. During the rotation of the roll 16, the strip steel is tempered. When a small amount of grit impurities are not completely adsorbed by the air extraction box 13 and remain on the surface of the cold-rolled strip steel, when the roll 16 tempers the cold-rolled strip steel, the grit impurities will be squeezed by the roll 16 and remain on the surface of the roll 16. At this time, through the brushes 31 fixedly connected to the inner side wall of the bottom plate 3, the grit impurities adhering to the surface of the roll 16 can be cleaned, reducing the situation that the grit impurities adhere to the surface of the conveying frame 17 and cause scratches on the cold-rolled strip steel surface.

[0028] As Figure 4As shown in the figure, a fixing frame 4 is fixedly connected to the inner side wall of the first support frame 11; an auxiliary wheel 41 is rotatably connected to the inner side wall of the fixing frame 4; when the cold-rolled strip steel moves towards the rolling roll 16 through the conveying frame 17, the side of the cold-rolled strip steel comes into contact with the auxiliary wheel 41. By rotatably connecting the auxiliary wheel 41 to the inner side wall of the fixing frame 4, it is possible to reduce the situation where the cold-rolled strip steel sways left and right during the forward movement of the cold-rolled strip steel, resulting in damage to the cold-rolled strip steel due to collision.

[0029] As Figure 4 shown in the figure, an auxiliary block 5 is slidably connected to the surface of the auxiliary wheel 41; the auxiliary block 5 has a frustum structure; a positioning frame 51 is fixedly connected to the end of the auxiliary block 5; a positioning hole 52 is opened at the end of the positioning frame 51; a positioning block 53 is fixedly connected to the top of the fixing frame 4; the positioning hole 52 and the positioning block 53 are correspondingly arranged. When the thickness of the cold-rolled strip steel that needs to be leveled is different, the position of the auxiliary block 5 is adjusted by pulling the positioning frame 51, and then it is fixed by passing a bolt through the positioning hole 52 and the positioning block 53. By slidably connecting the auxiliary block 5 to the surface of the auxiliary wheel 41, it is possible to reduce the amplitude of the up-and-down movement of the cold-rolled strip steel and reduce the situation of bumping. By fixedly connecting the positioning frame 51 to the end of the auxiliary block 5, opening the positioning hole 52 on the positioning frame 51, and fixedly connecting the positioning block 53 to the top of the fixing frame 4, it is possible to assist cold-rolled strip steels of different thicknesses to reduce the situation of bumping.

[0030] As Figure 4 shown in the figure, rubber blocks 6 are fixedly connected to the surface of the auxiliary block 5; the rubber blocks 6 are symmetrically arranged. When the cold-rolled strip steel slides on the surface of the auxiliary wheel 41, the side of the strip steel comes into contact with the rubber blocks 6. By fixedly connecting the rubber blocks 6 to the surface of the auxiliary block 5, it is possible to reduce the deformation of the strip steel caused by excessive pressure on the strip steel during the conveying process of the cold-rolled strip steel.

[0031] Working principle: When tempering cold-rolled strip steel, place the cold-rolled strip steel on the conveyor rack 17. At this time, air is pumped into the air extraction pipe 12. During the production and transportation of the cold-rolled strip steel, impurities such as dust and iron filings will adhere to its surface. When the cold-rolled strip steel moves to the bottom of the air extraction box 13, the air extraction box 13 adsorbs the grit impurities on the surface of the cold-rolled strip steel. By pumping air into the air extraction pipe 12, the air extraction box 13 adsorbs the grit impurities on the strip steel surface, reducing the situation where the grit impurities scratch the strip steel surface during the tempering process. During the forward movement of the cold-rolled strip steel, the convex block 22 rolls on the surface of the cold-rolled strip steel. At this time, the convex block 22 contacts the cold-rolled strip steel and knocks on the surface of the cold-rolled strip steel. When the cold-rolled strip steel is knocked, the grit impurities adhering to its surface are lifted up. Subsequently, the dust is adsorbed through the air extraction box 13. When a small amount of grit impurities are not completely adsorbed by the air extraction box 13, they will remain on the surface of the cold-rolled strip steel. When the rolling mill 16 tempers the cold-rolled strip steel, the grit impurities will be squeezed by the rolling mill 16 and remain on the surface of the rolling mill 16. At this time, the brush 31 fixedly connected to the inner side wall of the bottom plate 3 can clean the grit impurities adhering to the surface of the rolling mill 16. When the cold-rolled strip steel moves towards the rolling mill 16 through the conveyor rack 17, the side of the cold-rolled strip steel contacts the auxiliary wheel 41. By rotatably connecting the auxiliary wheel 41 to the inner side wall of the fixed frame 4, it is possible to reduce the situation where the cold-rolled strip steel is damaged due to collision caused by the left and right shaking of the cold-rolled strip during the forward movement of the cold-rolled strip steel. When the thickness of the cold-rolled strip steel to be tempered is different, by pulling the positioning frame 51 to adjust the position of the auxiliary block 5, and then fixing it by passing a bolt through the positioning hole 52 and the positioning block 53. By slidably connecting the auxiliary block 5 to the surface of the auxiliary wheel 41, it is possible to reduce the amplitude of the up and down movement of the cold-rolled strip steel and reduce the situation of bumping. When the cold-rolled strip steel slides on the surface of the auxiliary wheel 41, the side of the strip steel contacts the rubber block 6. The rubber block 6 fixedly connected to the surface of the auxiliary block 5 can reduce the deformation of the strip steel caused by excessive pressure on the strip steel during the transportation of the cold-rolled strip steel.

[0032] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
