[0018] A flipping method for a steel flipping device includes the following steps.

[0019] Step 1: Fix the cart driving device at the site of the rectangular material to be flipped. Both the right swing frame and the left swing frame are in a horizontal position. Start the trolley driving device and adjust the distance between the trolley and the first connecting plate to reach a preset distance. If it is necessary to flip the rectangular material to the left, go to Step 2. If it is necessary to flip the rectangular material to the right, go to Step 3.

[0020] Step 2: The cart driving device starts to adjust the position of the cart, and places the rectangular material on the right swing frame; then, the output end of the left swing cylinder retracts, driving the left swing frame to rotate clockwise around the connection point between the left swing frame and the cart until the left swing frame stands upright; after the left swing frame approaches the rectangular material, the output end of the left swing cylinder extends, causing the moving left swing frame to rotate counterclockwise around the connection point between the left swing frame and the cart until the left swing frame is horizontal, completing the leftward flip of the rectangular material.

[0021] Step 3: The cart driving device starts to adjust the position of the cart, and places the rectangular material on the left swing frame; then, the output end of the right swing cylinder retracts, driving the right swing frame to rotate counterclockwise around the connection point between the right swing frame and the cart until the right swing frame stands upright; after the right swing frame approaches the rectangular material, the output end of the right swing cylinder extends, causing the moving right swing frame to rotate clockwise around the connection point between the right swing frame and the cart until the right swing frame is horizontal, completing the rightward flip of the rectangular material.

[0022] The cart driving device used is a cart moving oil cylinder; the output end of the cart moving oil cylinder is connected to one side of the cart; the cart driving device used is a cart moving oil cylinder; the cart moving oil cylinder is horizontally arranged and its bottom is fixed at the end of the side of the cart away from the cart driving device; the output end of the cart moving oil cylinder is connected to the cart.

[0023] The preset distance in Step 1 is: the distance between the left swing frame after standing upright and the first connecting plate is equal to the height of the first support roller connecting plate.

[0024] Beneficial effects:

[0025] (1) The present invention is composed of a cart, a cart driving device, a right rolling mechanism, a cart, a cart driving device, and a left rolling mechanism. By starting the cart driving device to adjust the position of the cart, the rectangular material can be conveniently placed on the left swing frame or the right swing frame for subsequent rightward or leftward flipping.

[0026] (2) By starting the cart driving device, the purpose of adjusting the distance between the right rolling mechanism and the left rolling mechanism is achieved. Through the retraction of the output end of the left swing cylinder on the left rolling mechanism, the left swing frame on the left rolling mechanism rotates clockwise around the connection point between the left swing frame and the cart until the left swing frame stands upright; after the left swing frame approaches the rectangular material, the output end of the left swing cylinder extends, causing the moving left swing frame to rotate counterclockwise around the connection point between the left swing frame and the cart until the left swing frame is horizontal, conveniently and accurately completing the leftward flip of the rectangular material, thereby efficiently straightening or performing other treatments on the rectangular material.

[0027] (3) In the present invention, when the output end of the right swing cylinder on the right rolling mechanism retracts, it drives the right swing frame on the rolling mechanism to rotate counterclockwise around the connection point between the right swing frame and the cart until the right swing frame is erected. After the right swing frame approaches the rectangular material, the output end of the right swing cylinder extends outward, causing the moving right swing frame to rotate clockwise around the connection point between the right swing frame and the cart until the right swing frame is horizontal, conveniently and accurately completing the rightward flipping of the rectangular material, thereby efficiently straightening or performing other treatments on the rectangular material.

Step 3: The large vehicle driving device starts to adjust the position of the large vehicle (10) and places the rectangular material (11) on the left swing frame (4); then, the output end of the right swing cylinder (8) retracts, driving the right swing frame (7) to rotate counterclockwise around the connection point between the right swing frame (7) and the large vehicle (10) until the right swing frame (7) stands upright; after the right swing frame (7) approaches the rectangular material (11), the output end of the right swing cylinder (8) extends, causing the right swing frame (7) to rotate clockwise around the connection point between the right swing frame (7) and the large vehicle (10) until the right swing frame (7) is horizontal, completing the rightward flipping of the rectangular material (11).

3. The flipping method of a steel flipping device according to claim 2, characterized in that: The large vehicle driving device adopted is a large vehicle moving oil cylinder (1); the output end of the large vehicle moving oil cylinder (1) is connected to one side of the large vehicle (10); the small vehicle driving device adopted is a small vehicle moving oil cylinder (9); the small vehicle moving oil cylinder (9) is horizontally arranged and its bottom is fixed at the end of the side of the large vehicle (10) away from the large vehicle driving device; the output end of the small vehicle moving oil cylinder (9) is connected to the small vehicle (5).

4. The flipping method of a steel flipping device according to claim 2, characterized in that: The preset distance described in Step 1 is: the distance between the erected left swing frame (4) and the first connecting plate (13) is equal to the height of the first support roller connecting plate (18).
