[0016] To make the objectives, contents and advantages of the present invention clearer, the following further describes the specific embodiments of the present invention in detail with reference to the drawings and embodiments.

[0017] This embodiment provides a hot forming and shaping device for a U-shaped deck, and its structure is as Figure 1 and 2 shown, including a die holder 2, guide columns 1, positioning columns 3, adjusting screws 4 and lifting lugs 5.

[0018] The die carrier 2 is an H-shaped frame structure welded by rectangular square tubes and triangular blocks, which is divided into three layers: upper, middle and lower. Among them, the middle layer is a long grid structure welded by six rectangular square tubes (one at each of the four sides and two parallel ones in the middle); the upper layer includes nine rectangular square tubes and four triangular blocks. The upper rectangular square tubes at the left and right ends are welded to the top of the middle layer rectangular square tubes through supporting square tubes. The other seven upper rectangular square tubes are located between the upper rectangular square tubes at the left and right ends and have the same placement direction and are directly welded to the top of the middle layer rectangular square tubes. The upper rectangular square tubes at the left and right ends are respectively supported by two welded triangular blocks; the lower layer includes six rectangular square tubes and six square tube legs. The lower layer rectangular square tubes are welded to the bottom of the middle layer and have the same placement direction as the upper layer rectangular square tubes. The six square tube legs are respectively welded to the four corners and the middle positions of the edges of the lower surface of the middle layer.

[0019] The inner side dimension L1 of the upper rectangular square tubes at the left and right ends of the die carrier 2 is the same as the outer skin opening dimension of the U-shaped deck. The outer side dimension L2 of the lower rectangular square tubes at the left and right ends of the die carrier 2 is the same as the inner skin opening dimension of the U-shaped deck. After the U-shaped deck is placed in the shaping device, the inner and outer skin opening dimensions during the cooling process are controlled by the hot forming shaping device, so as to ensure the opening dimension of the U-shaped deck after cooling.

[0020] Guide columns 1 are respectively fixed at the four corners of the upper layer of the die carrier 2. The inner diameter of the square tube legs of the lower layer of the die carrier 2 has a transition fit with the diameter of the guide column 1. When multiple shaping devices are stacked up and down, the guide column 1 of the lower hot forming shaping device is inserted into the square tube legs of the upper hot forming shaping device.

[0021] Four positioning columns 3 are installed on the surface of the upper rectangular square tubes of the die carrier 2 by screws, and the installation positions are the same as those of the positioning tooling during the hot forming of the U-shaped deck.

[0022] Adjusting screws 4 are installed on the upper surfaces of the middle five of the upper rectangular square tubes of the die carrier 2 and the lower surfaces of the middle four of the lower rectangular square tubes by means of threaded connection. When multiple shaping devices of the present invention are stacked up and down, the adjusting screws 4 on the upper surface of the lower shaping device are in contact with the lower surface of the U-shaped deck, and the adjusting screws 4 on the lower surface of the upper shaping device are in contact with the upper surface of the U-shaped deck. By adjusting the height of the adjusting screws 4 through the thread, the adjusting screws 4 above and below work together to correct the shape of the bottom surface of the U-shaped deck and ensure the flatness of the bottom surface.

[0023] Four lifting lugs 5 are connected to the side of the die carrier 2 by welding.

[0024] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
