[0030] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0031] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] As Figure 1As shown, the embodiment discloses a billet straightening simple tool, which comprises a pressing plate 1. The pressing plate 1 is in the shape of a cuboid, and the length direction of the pressing plate 1 can cover and flatten the billet. The opposite side walls of the pressing plate 1 are respectively defined as a front surface and a back surface. The front surface of the pressing plate 1 is used to flatten the billet. Two fixing holes 10 are formed on the back surface of the pressing plate 1, and the two fixing holes 10 are arranged at intervals. The shapes of the two fixing holes 10 are matched with the clamping arms of the clamp trolley. It is worth noting that when the clamping arms of the clamp trolley are curved arms, the shapes and sizes of the two fixing holes 10 are slightly larger, so that the clamping arms of the clamp trolley can smoothly pass through the corresponding fixing holes 10.

[0034] Four first fixing plates 2 are arranged on the back surface of the pressing plate 1. Each two first fixing plates 2 are arranged on the periphery of one of the fixing holes 10. Each two first fixing plates 2 are arranged on the opposite sides of one of the fixing holes 10, that is, the center axes of the two first fixing plates 2 located on the two sides of the fixing hole 10 coincide. A first screw hole is formed on the side wall surface of each first fixing plate 2, and the center axis of the first screw hole is consistent with the center axis of the first fixing plate 2.

[0035] A first screw bolt 20 is threadedly connected to each first fixing plate 2 through the corresponding first screw hole. There are four first screw bolts 20 in total. The first clamping plate 201 is arranged on one end of each first screw bolt 20, which faces the clamping arm of the clamp trolley.

[0036] In the embodiment, in order to improve the flattening performance of the pressing plate 1 to the billet, the front surface of the pressing plate 1 is kept flat with the clamping surface of the clamping arm of the clamp trolley. During the process that the clamping arm of the clamp trolley clamps the billet, if the two ends of the billet are raised too high, the pressing plate 1 can gradually flatten the two ends of the billet that are raised until the clamping arm of the clamp trolley clamps the billet.

[0037] The working principle of the embodiment is as follows: the end of the clamping arm of the clamp trolley is aligned with the fixing hole 10 on the pressing plate 1, so that the clamping arm can pass through the fixing hole 10 on the pressing plate 1, and the pressing plate 1 is hung on the clamping arm of the clamp trolley. At this time, the pressing plate 1 is not stable on the clamping arm of the clamp trolley, and may fall off. Then, the first screw bolt 20 on each first fixing plate 2 is tightened towards the clamping arm located in the fixing hole 10, until the first clamping plate 201 on each first screw bolt 20 contacts and presses the outer wall surface of the clamping arm, so that the pressing plate 1 can be fixed on the outer wall surface of the clamping arm and will not fall off. After the clamping arm of the clamp trolley clamps the billet, the pressing plate 1 fixed on the outer wall surface of the clamping arm can simultaneously flatten the billet, so as to avoid the situation that the two ends of the billet are raised after the billet is clamped by the clamping arm.

[0038] Embodiment 2

[0039] This embodiment is further optimized on the basis of embodiment one, for details, please refer to Figure 1 As shown in the figure, the back of the pressing plate 1 is provided with four second fixing plates 3, wherein every two second fixing plates 3 are provided as two groups around the two fixing holes 10. Every two second fixing plates 3 are arranged on opposite sides of the two fixing holes 10, that is, the center axes of the two second fixing plates 3 located on both sides of the fixing hole 10 coincide. Second threaded holes are opened on the side wall surface of each second fixing plate 3, and the center axes of the second threaded holes coincide with the center axes of the second fixing plates 3.

[0040] Two second bolts 30 are threadedly connected on each second fixing plate 3 through the corresponding second threaded holes, and there are a total of four second bolts 30. Each second bolt 30 is provided with a second clamping plate 301 at one end thereof facing the clamping arm of the clamp trolley.

[0041] In this embodiment, in order to improve the clamping stability of the first clamping plate 201 and the second clamping plate 301 when they are pressed on the outer surface of the clamping arm of the clamp trolley, anti-skid pads 50 are arranged on the clamping surface of the first clamping plate 201 and the clamping surface of the second clamping plate 301. It should be noted that since the square billet clamped by the clamping arm of the clamp trolley has a high temperature, the material of the anti-skid pads 50 should be made of a material such as asbestos that can withstand high temperature, so as to better adapt to the surrounding environment with high temperature of the square billet. In addition, the first fixing plate 2, the second fixing plate 3, the first clamping plate 201, the second clamping plate 301, the first bolt 20 and the second bolt 30 are all made of high-temperature-resistant materials to better adapt to the working environment of clamping the square billet.

[0042] The working principle of this embodiment is as follows: after the clamping arm of the clamp trolley passes through the fixing hole 10 on the pressing plate 1, the first bolt 20 on the side wall surface of the first fixing plate 2 and the second bolt 30 on the side wall surface of the second fixing plate 3 are tightened towards the clamping arm located in the fixing hole 10, so that the first clamping plate 201 on the end of the first bolt 20 and the second clamping plate 301 on the end of the second bolt 30 are pressed on the outer wall surface of the clamping arm, and the pressing plate 1 can be more firmly and stably fixed on the clamping arm to prevent the pressing plate 1 from falling off from the clamping arm when the pressing plate 1 is pressed on the square billet clamped by the clamping arm. In addition, since there are many types of clamping arms of the clamp trolley, for the clamp trolley with an arc-shaped clamping arm, arc-shaped first clamping plate 201 and second clamping plate 301 can be used to strengthen the clamping stability of the first clamping plate 201 and the second clamping plate 301.

[0045] In the embodiment, in order to enhance the support stability of the support plate 5, the support rod 6 is arranged on the back of the pressing plate 1, the other end of the support rod 6 is connected with the support plate 5, so that the support rod 6, the support plate 5 and the pressing plate 1 form a triangular structure, thereby improving the support stability of the support plate 5.

[0046] Embodiment 4

[0047] The embodiment is a further optimization based on the embodiment one, and the specific process is described in the embodiment one.
