[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, a processing mold for arc-shaped angle steel on the top of a dome tank comprises a positioning plate 1, a workpiece fixture 2 and a power part 3. A plurality of positioning plates 1 are provided, and the plurality of positioning plates 1 are arranged and distributed according to the arc shape required for processing the workpiece. The power part 3 is used to pull one end of the workpiece to be bent toward one side of the positioning plate 1.

[0021] During the processing operation of the workpiece, multiple positioning plates 1 are arranged in sequence according to the arc that the workpiece needs to be bent as per the processing drawing. After fixing the workpiece with the workpiece fixture 2, the end to be bent of the workpiece is pulled towards one side of the positioning plate 1 by the power part 3. During the bending process of the workpiece, the positioning plate 1 supports and limits one side of the workpiece, enabling one side of the workpiece to fully adhere to the positioning plate 1, thus realizing the shaping and processing operation of the workpiece.

[0022] The workpiece fixture 2 includes a first part and a second part 2.1. Multiple first parts are equidistantly arranged along the length direction of the workpiece, and the multiple first parts press down on the top of the workpiece. By pressing on the top of the workpiece, the first part can prevent the workpiece from shifting or flipping during the shaping and processing operation of the workpiece, ensuring the stability of the workpiece.

[0023] The second part 2.1 is arranged at the other end of the workpiece, and the second part 2.1 and the positioning plate 1 are distributed on both sides of the workpiece. Specifically, when the power part 3 pulls the end to be bent of the workpiece, the second part 2.1 cooperates with the positioning plate 1 on the opposite side to fix the other end of the workpiece, so as to ensure that the workpiece can be effectively pulled and shaped by the power part 3.

[0024] Among them, both the positioning plate 1 and the second part 2.1 are made of steel plates. Of course, in other embodiments, the positioning plate 1 and the second part 2.1 can be made of angle steel or I-beam, which is not limited here.

[0025] The first part includes a pressing plate 2.2 and a bracket 2.3. The pressing plate 2.2 is used to press down on the top of the workpiece, and a bracket 2.3 is arranged at both ends of the pressing plate 2.2. The bracket 2.3 is used to apply a downward pressing force to the pressing plate 2.2. Specifically, when the pressing plate 2.2 spans across the top of the workpiece and the bracket 2.3 applies a downward pressing force to the pressing plate 2.2, the workpiece is supported at the bottom of the pressing plate 2.2, so that while the pressing plate 2.2 applies a downward pressing force to the workpiece, the pressing plate 2.2 is stably supported.

[0026] The support is in a "C" - shaped structure, and the bracket 2.3 is sleeved on the end of the pressing plate 2.2. Specifically, the bottom end of the bracket 2.3 is fixed to the ground. The first part further includes a wedge - shaped plate 2.4, and the wedge - shaped plate 2.4 is inserted between the top of the pressing plate 2.2 and the inner top wall of the bracket 2.3. During the process of fixing the pressing plate 2.2 with the bracket 2.3, the pressure of the bracket 2.3 on the pressing plate 2.2, and thus the pressure of the pressing plate 2.2 on the workpiece, can be controlled by controlling the depth of insertion of the wedge - shaped plate 2.4 between the top of the pressing plate 2.2 and the inner top wall of the bracket 2.3.

[0027] The power part 3 includes an electric guide chain 3.1, a fixing plate 3.2 and a sliding fixture 3.3. The electric guide chain 3.1 is fixed on the ground through the fixing plate 3.2. The sliding fixture 3.3 is connected to the electric guide chain 3.1. The sliding fixture 3.3 is used to hook on one end of the workpiece to be bent. After the workpiece is fixed by the workpiece fixture 2, the sliding fixture 3.3 is hooked on the one end of the workpiece to be bent, and then the electric guide chain 3.1 is started. The electric guide chain 3.1 pulls one end of the workpiece through the sliding fixture 3.3, so that the workpiece is bent.

[0028] The arc angle steel processing mold for the arch tank top preferably includes a platform 4, and the positioning plate 1, the processing fixture and the power part 3 are all installed on the platform 4.

[0029] Specifically, the positioning plate 1, the second part 2.1, the bracket 2.3 and the fixing plate 3.2 are all fixed on the platform 4 by spot welding. After the workpiece is processed, the positioning plate 1, the second part 2.1, the bracket 2.3 and the fixing plate 3.2 can be directly removed from the platform 4 by knocking.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
