[0016] As shown in the figure, the finished product of the utility model is a semicircular structure product. Before processing, the product is a disc with an edge of several centimeters in height. After processing, the finished product is hollow in the middle and has a C-shaped groove structure at the edge.

[0017] The semicircular forming device of the present invention includes a support base 901 having a through hole therein, in which are mounted three modules and a guide block 905. The three modules are a first module 902, a second module 903, and a third module 904. The first module 902 and the third module 904 are positioned at the shoulders of the guide block 905, while the second module 903 is positioned on the front of the guide block 905. That is, the first module 902 and the third module 904 are positioned along the X-axis of the guide block 905, while the second module 903 can be positioned along the Y-axis.

[0018] The three modules form a semicircular structure after being unfolded. During the unfolding process, the first module 902 and the third module 904 unfold in opposite directions, and the second module 903 unfolds outward, thereby increasing the volume of the entire module. In addition, the processing object is a punching disc 912. Therefore, no matter at what angle the punching disc is placed outside the three modules, the punching disc can be stretched to form a semicircular workpiece with a semicircular structure.

[0019] The three modules are movably connected to the guide block 905; the guide block 905 is equipped with a pushing device, which pushes the guide block 905 to move up and down in the through hole of the support seat 901, and when moving upward, the three modules are unfolded and combined to form a semicircular structure. A slide groove or a slide rail is provided on the guide block 905, and corresponding slide rails or slide grooves corresponding to the guide block 905 slide groove or the slide rail are provided at corresponding positions on the three modules. For example, if a slide rail is provided on the guide block 905, a slide groove can be provided on the module. If a slide groove is provided on the guide block 905, a protruding slide rail structure is provided on the module, so that the two can move or slide in a straight line relative to each other, and can remain without falling off during the sliding process. The guide portion 906 of the guide block 905 gradually increases from top to bottom, so that the guide block 905 can spread the three modules during the upward movement and can close the three modules during the downward movement. The connecting portion 907 of the guide block 905 is connected to a driving device, which can be a cylinder driving device, a motor driving device, or a screw driving device. The driving device can be directly connected to the connecting portion of the guide block to drive it to move. The present invention preferably uses a screw driving device. For example, the driving device of the guide block 905 includes a slider 909, on which are mounted a plurality of screws 910. When the motor configured with the screws rotates, the slider can move up and down. The slider contacts the connecting portion 907 of the guide block 905 to drive the guide block 905 to move.

[0020] The working principle of the semicircular forming device of the utility model:

[0021] This device processes a punching disc 912. Punching disc 912 is hollow, similar to a circular ring, with an inwardly constricted edge. Punching disc 912 is obtained by punching holes in a closed disc 914. That is, closed disc 914 is formed into a closed disc 913, which is then punched into punching disc 912. Punching disc 912 is then stretched using the device of this invention to produce a semicircular workpiece 911.

[0022] After the punching disc is placed on the semicircular forming device, the pushing device is started to move the guide block 905 upward. The connection between the guide block 905 and the three modules is inclined. During the upward movement of the guide block 905, the three modules are driven to expand horizontally. When expanding, the disc is stretched into the same shape as the semicircle after being formed by the three modules, and a semicircular workpiece 911 is obtained. After the semicircular workpiece is processed, it is removed from the guide block 905 using a clamping mechanism and then moved to the material receiving device; at this time, the guide block 905 moves downward under the drive of the pushing device and returns to its initial position.

[0023] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
