[0021] The names of the messages or information exchanged between multiple devices in the implementation manner of the present utility model are only used for illustrative purposes, and are not used to limit the scope of these messages or information. Example

[0022] like Figure 1-3 As shown, an irregular upper side beam roll bending die for box cargo includes a fixed die 1 and a movable die 2, the fixed die 1 includes a disc-shaped fixed upper die 11, a fixed middle die 12 and a fixed lower die 13, the fixed upper die 11, the fixed middle die 12 and the fixed lower die 13 are coaxially stacked from top to bottom, and keyways 3 are provided at the axial holes of the fixed upper die 11, the fixed middle die 12 and the fixed lower die 13, the diameter of the fixed middle die 12 is smaller than the diameter of the fixed upper die 11 and the fixed lower die 13, and an annular groove is formed between the fixed upper die 11 and the fixed lower die 13 (for limiting support on both sides of the profile 8B surface), a first annular protrusion 14 is provided in the middle of the side surface of the fixed middle die 12 (for limiting support on the profile 8C surface), and a concave platform 15 is provided at the lower part of the side surface of the fixed upper die 11 (the concave platform 15 facilitates bending at the connection between the profile 8A surface and the profile 8B surface);

[0023] The movable mold 2 includes a disc-shaped movable upper mold 21, a first movable middle mold 22, a second movable middle mold 23 and a movable lower mold 24. The movable upper mold 21, the first movable middle mold 22, the second movable middle mold 23 and the movable lower mold 24 are coaxially stacked from top to bottom, and keyways 3 are provided at the axial holes of the movable upper mold 21, the first movable middle mold 22, the second movable middle mold 23 and the movable lower mold 24. The diameter of the second movable middle mold 23 is smaller than that of the first movable middle mold 22 and the movable lower mold 24, and a second annular groove is formed between the first movable middle mold 22 and the movable lower mold 24. A second annular protrusion 25 is provided in the middle part of the side surface of the second movable middle mold 23, and a third annular protrusion 26 is provided on the upper part of the side surface of the movable upper mold 21.

[0024] Both the fixed mold 1 and the movable mold 2 are assembled from multiple molds and can be adjusted according to the cross-section of the profile 8 so that the protrusions and grooves on the fixed mold 1 and the movable mold 2 match the cross-section of the profile 8, thereby expanding the adaptability range and realizing the reuse of the molds and reducing the repeated production of the molds. At the same time, the fixed mold 1 and the movable mold 2 of the split structure are both provided with keyways 3. After the fixed mold 1 and the movable mold 2 are mounted on the rotating shaft of the roller rolling machine, a fixed connection with the rotating shaft is achieved through the keyway 3, which prevents the rotating shaft and the mold from sliding relative to each other, and also ensures that the molds do not slide relative to each other during assembly, thereby ensuring the quality of the roller bending.

[0025] The technical solution formed by the above embodiment replaces the fixed mold 1 and the movable mold 2 of the roll-up machine in the prior art to form another technical solution disclosed in the present application. The technical solution is: Figure 1-4 As shown, an irregular upper side beam roll bending machine for box cargo includes a frame 4, a fixed mold 1 and a movable mold 2. The movable mold 2 and two fixed molds 1 are arranged on the frame 4 in a herringbone shape. The movable mold 2 is sleeved on the driving shaft 5, and the fixed mold 1 is sleeved on the driven shaft 6. A key is placed in the keyway 3. After being pressed and fixed by bolts 7, the driving motor drives the two driving shafts 5 to rotate in the same direction through the transmission mechanism, thereby realizing the same direction rotation of the two fixed molds 1. The driven shaft 6 reciprocates along the central axis of the two fixed molds 1 under the action of the moving mechanism to realize the movement of the movable mold 2, and the profile 8 arranged between the fixed mold 1 and the movable mold 2 is roll-bent.

[0026] The process of using the overall technical solution formed by the above embodiments is as follows: the profile 8 (upper side beam) is placed between the movable mold 2 and the fixed mold 1, and the movable mechanism realizes that the movable mold 2 moves toward the fixed mold 1 along the central axis of the two fixed molds 1, and the profile 8 is clamped between the movable mold 2 and the fixed mold 1. Since the protrusions and grooves on the fixed mold 1 and the movable mold 2 match the cross-section of the profile 8, the limitation and support of the profile 8 are guaranteed (the fixed upper mold 11 and the movable upper mold 21 contact both sides of the profile 8A surface). At this time, the movable mechanism continues to realize that the movable mold 2 moves toward the fixed mold 1 along the central axis of the two fixed molds 1, and the driving motor drives the two fixed molds 1 to rotate in one direction at the same time through the transmission mechanism, and then reverses. Due to the movement of the profile 8, the movable mold 2 and the driven shaft 6 can rotate accordingly, thereby completing the roller bending operation of the profile 8 (upper side beam) reciprocatingly. After that, the movable mechanism realizes that the movable mold 2 moves away from the fixed mold 1 along the central axis of the two fixed molds 1, and the profile 8 can be taken out.

[0027] In the present application, the structure in which the driving motor drives the two driving shafts 5 to rotate through the transmission mechanism, and the structure in which the moving mechanism realizes the reciprocating movement of the driven shaft 6 along the central axis of the two fixed molds 1 both adopt the structure of the existing technology. At the same time, these two structures are not improved in the present application and are not the innovation points of the present application. Therefore, these two structures are not described in detail in the present application.

[0028] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
