[0015] Compared with the prior art, the invention has the following beneficial effects: the straightening rolling guide device for the finished straight and flat steel products of wear-resistant alloy steel is

[0016] (1) The present invention can effectively solve the problem that the existing straight flat steel is prone to warping after hot rolling through the coordinated use of the straightening mechanism and the first hydraulic cylinder, and the existing guide device does not have the straightening function, so it is necessary to guide the finished straight flat steel after hot rolling to the straightening device with the external conveying device for correction, thereby affecting the production efficiency of the finished straight flat steel. While the motor drives the second straightening roller to rotate, the second straightening roller drives the first straightening roller to rotate in the same direction through the gear transmission structure, so that the first straightening roller and the second straightening roller can be used to guide and straighten the straight flat steel in the straightening groove, thereby shortening the processing flow of the straight flat steel and improving the production efficiency of its finished products. In addition, the staff can adjust the positions of the second straightening roller and the first straightening roller by controlling the extension length of the first hydraulic cylinder, so as to facilitate the selective selection of straightening grooves of different depths and widths for guiding and straightening according to the actual processing requirements of the straight flat steel, thereby improving the flexibility of the device structure and expanding the scope of application of the device;

[0017] (2) The present invention can effectively solve the problem that the existing straightening device usually heats the straight flat steel during the straightening process to ensure the straightening effect and efficiency, thereby causing high energy consumption in the production process, through the coordinated use of the driven rotating mechanism and the straightening mechanism. The motor drives the first straightening roller and the second straightening roller to rotate to guide and straighten the rollers, and simultaneously drives the fan blade assembly connected to one side to rotate. When the fan blade assembly rotates, it extracts heat from the external hot rolling equipment through the heat delivery pipe, and discharges the extracted heat to the inside of the air storage box through the air pipeline. The heat entering the air storage box is sprayed to the upper and lower sides of the straight flat steel through the nozzle to heat it, thereby ensuring the straightening effect of the first straightening roller and the second straightening roller on the straight flat steel, and at the same time reducing the energy consumption generated by the straightening;

[0018] (3) The present invention can effectively solve the problem that the existing guide device has a fixed structure and cannot adjust its guide height according to actual needs through the coordinated use of the first hydraulic cylinder and the supporting plate. The first hydraulic cylinder pushes the supporting plate and the straightening mechanism on the top of it to move upward, so that the guide height of the device can be adjusted. When the height is adjusted, it means that the device has entered the use stage. At this time, the column at the bottom of the supporting plate pulls the lifting frame to move upward away from the ground, so that the base contacts the ground to support the device, preventing the device from accidentally moving during use and affecting normal operation. Conversely, when the device is used, the first hydraulic cylinder pulls the supporting plate to move down and reset. At this time, the column pushes the lifting frame to move down so that the roller contacts the ground, so that the roller can be used to move the device for storage, thereby improving the flexibility of the device.

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-6 The present invention provides a technical solution: a rolling guide device for straightening and guiding the finished straight and flat steel products of wear-resistant alloy steel at the outlet.

[0028] Embodiment 1

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a straightening mechanism 2 is arranged on the top of the supporting plate 1, and the straightening mechanism 2 includes a frame 201, a first straightening roller 202, a second straightening roller 203, a straightening groove 204, a gear transmission structure 205, a belt transmission structure 206 and a motor 207. The first straightening roller 202 and the second straightening roller 203 are both rotatably connected to the inner side of the frame 201, and four groups of straightening grooves 204 are opened on the second straightening roller 203. At the same time, the first straightening roller 202 is connected to the second straightening roller 203 through the gear transmission structure 205. The first straightening roller 202 and the second straightening roller 203 are evenly spaced on the inner side of the frame 201. Two adjacent groups of first straightening rollers 202 are connected through the belt transmission structure 206, and two adjacent groups of second straightening rollers 203 are connected through the belt transmission structure 206. At the same time, the second straightening roller 203 is connected to the output end of the motor 207.

[0030] In a further embodiment, a sphere 7 is provided at the bottom of the frame 201, and the sphere 7 is arranged inside a limiting groove 8. At the same time, the two opposite side surfaces of the frame 201 are fixedly connected to the baffle 5 on the supporting plate 1 through a first hydraulic cylinder 4. The sphere 7 and the limiting groove 8 provide support and limit for the movement of the frame 201 during its movement.

[0031] In a further embodiment, the frame 201 is slidably connected to the inside of the base 6 , and a driven rotating mechanism 3 is provided on the frame 201 .

[0032] In a further embodiment, the widths of the four groups of straightening grooves 204 on the second straightening roller 203 are increasing from left to right, and the depths of the four groups of straightening grooves 204 on the second straightening roller 203 are increasing from left to right.

[0033] In a further embodiment, the limiting groove 8 is provided on the top of the bearing plate 1 , and the bottom of the top of the bearing plate 1 is connected with the column 9 and the second hydraulic cylinder 12 , and the column 9 is symmetrically arranged on the outside of the second hydraulic cylinder 12 .

[0034] In a further embodiment, a lifting frame 10 is connected to the bottom of the column 9, and a roller 11 is installed at the bottom of the lifting frame 10. At the same time, the lifting frame 10 and the roller 11 are both arranged inside the through groove 13. The through groove 13 is symmetrically opened in the base 6, and the base 6 is connected to the supporting plate 1 through the second hydraulic cylinder 12. At the same time, the second hydraulic cylinder 12 is installed inside the base 6.

[0035] Specifically, in the actual working process, the power supply is connected to start the device, and the first hydraulic cylinder 4 pushes the load-bearing plate 1 and the straightening mechanism 2 on the top thereof to move upward until the height reaches the required position. During the upward movement of the load-bearing plate 1, the column 9 at the bottom pulls the roller 11 on the lifting frame 10 to move upward and away from the ground synchronously, so that the base 6 contacts the ground to support the device, thereby preventing the roller 11 from being damaged due to long-term support. Then, the staff can adjust the position of the second straightening roller 203 and the first straightening roller 202 by controlling the extension length of the first hydraulic cylinder 4, that is, selectively select straightening grooves 204 of different depths and widths for guiding and straightening according to the actual processing requirements of the straight flat steel. After the adjustment is completed, the straight flat steel product after hot rolling enters the straightening groove 204, and the internal motor 207 drives the second straightening roller 203 to rotate. At the same time, the second straightening roller 203 drives the first straightening roller 202 to rotate in the same direction through the gear transmission structure 205, so that the first straightening roller 202 and the second straightening roller 203 can be used to guide the straight flat steel in the straightening groove 204 and straighten it at the same time. The driven rotating mechanism 3 heats the straight flat steel product during the straightening process. After the device is used, the first hydraulic cylinder 4 is controlled to pull the load plate 1 down and reset. At this time, the column 9 pushes the lifting frame 10 to move down so that the roller 11 contacts the ground, so that the roller 11 can be used to move the device to the desired position.

The one-way valve prevents the backflow of heat inside the gas pipeline 303 and the heat delivery pipe 306, thereby improving the rationality of the device structure.

[0042] Specifically, the motor 207 drives the multiple groups of first straightening rollers 202 and second straightening rollers 203 to rotate for guiding and straightening, and simultaneously drives the fan blade assembly 301 connected to one side thereof to rotate. When the fan blade assembly 301 rotates, the heat of the external hot rolling equipment is extracted through the heat delivery pipe 306, and the extracted heat is discharged to the inside of the gas storage box 304 through the gas pipeline 303. The heat entering the gas storage box 304 is sprayed to the upper and lower sides of the straight flat steel through the nozzle 305 to heat it, thereby ensuring the straightening effect of the straight flat steel entering between the first straightening roller 202 and the second straightening roller 203 for straightening.
