By arranging the power device, the connecting device and the protective plate, the plate is prevented from warping too high and damaging other equipment.
[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0005] A protection device for preventing plate warping, comprising a power device, a connecting device and a protective plate, the power device is fixed on one side of the frame at the discharge of the rolling mill; the connecting device is arranged at the lower part of the power device, and the connecting device is connected with the power device, and the power device provides power for the connecting device; the protective plate is connected with the connecting device, and the connecting device drives the protective plate to rotate, so that the protective plate is in the upper part of the discharge of the rolling mill in the working state.
[0006] Further, the power device is a telescopic rod, and the telescopic rod is fixed on the frame on one side at the discharge of the rolling mill. The connecting rod is driven to move downward by the telescopic rod, so that the connecting rod drives the shaft to rotate.
[0007] Further, a fixed seat is fixed on the frame on one side at the discharge of the rolling mill, and the fixed end of the telescopic rod is rotatably arranged on the fixed seat.
[0008] Further, the connecting device comprises a connecting rod and a shaft, the shaft is arranged at the upper part of the discharge of the rolling mill, and the shaft is rotatably connected with the frames on both sides of the discharge of the rolling mill; the protective plate is fixedly connected with the shaft; one end of the connecting rod is rotatably connected with the output end of the power device, and the other end is fixedly connected with the end part of the shaft. The center of gravity of the connection between the shaft and the connecting rod and the extension direction of the piston rod of the hydraulic cylinder are not on the same straight line, so that when the piston rod of the hydraulic cylinder is extended and retracted, the connecting rod and the shaft can be driven to rotate instead of exerting external force on the center of gravity of the connection between the shaft and the connecting rod.
[0009] Furthermore, connecting seats are fixed on the arches on both sides of the discharge port of the rolling mill, and the connecting seats are rotatably connected to the shaft.
[0010] Furthermore, the protective plate is provided with multiple connecting plates spaced apart along its length, and the connecting plates are fixed to the shaft.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:
[0013] This invention, through the design of a power unit, connecting device, and protective plate, prevents the sheet metal from warping excessively during mill discharge, thus avoiding damage to the thickness gauge at the mill's discharge point. The arc-shaped structure of the protective plate prevents excessive pressure on the sheet metal when it bulges in the middle, thus preventing discharge difficulties at the outlet. The connecting plate enhances the connection strength between the protective plate and the shaft, increasing the stability of the protective plate. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0018] like Figure 1 and Figure 2 As shown, this embodiment provides a protective device to prevent sheet metal from warping, including a power unit, a connecting device, and a protective plate 6. The power unit is fixed to the archway 8 on one side of the mill discharge point 9. The power unit is a telescopic rod 1. A fixing seat 2 is fixed to the archway 8 of the mill discharge point 9, and the fixed end of the telescopic rod 1 is rotatably connected to the fixing seat 2. In this embodiment, the telescopic rod 1 is a hydraulic telescopic rod 1, and the telescopic rod 1 is connected to the hydraulic system of the mill.
[0019] The power device is connected with a connecting device at the lower part, the connecting device comprises a shaft 4 and a connecting rod 3, a connecting seat 5 is fixedly connected on the housing 8 on both sides of the mill discharging part 9, and the shaft 4 is rotationally connected with the connecting seat 5. One end of the connecting rod 3 is rotationally connected with the output end of the telescopic rod 1, and the other end is fixedly connected with the end of the shaft 4. The gravity center of the connecting position of the shaft 4 and the connecting rod 3 and the telescopic direction of the piston rod of the hydraulic cylinder are not in a straight line, so that when the piston rod of the hydraulic cylinder is telescoped, the connecting rod 3 and the shaft 4 can be driven to rotate instead of exerting an external force on the gravity center of the connecting position of the shaft 4 and the connecting rod 3.
[0020] The protective plate 6 is arranged at the lower part of the connecting device, the protective plate 6 is concave in the length direction and is in an arc-shaped structure, so that when the middle part of the plate 10 is bulged, the extrusion of the protective plate 6 on the plate 10 is prevented from being too large to cause discharging difficulty at the discharging port. A plurality of connecting plates 7 are arranged at intervals in the length direction of the protective plate 6, the connecting plates 7 are connected with the shaft 4, the connecting strength of the protective plate 6 and the shaft 4 is improved, and the stability of the protective plate 6 is increased.
[0021] When the mill discharges, the telescopic rod 1 is started, the output end of the telescopic rod 1 drives the top of the connecting rod 3 to move downward, the connecting rod 3 is rotated downward with the center of the shaft 4 as the center under the pushing of the telescopic rod 1, the connecting rod 3 drives the shaft 4 to rotate downward, the shaft 4 drives the protective plate 6 to rotate downward to the vertical state with the plate 10 at the mill discharging part 9. When the plate 10 is warped, the warped part of the plate 10 is in contact with the protective plate 6, when the angle of the warped part of the plate 10 is too large, the plate 10 in contact with the protective plate 6 is extruded by the protective plate 6 to reduce the warped angle, so that the damage to other instruments at the mill discharging port caused by the excessively high warped angle is prevented.
