It can ensure that the parts are clamped and rolled into shape in one clamping, and the molding consistency and processing efficiency of the parts are high, meeting the design and processing requirements.
[0047] 2. The linear mold uses a pre-tightened linear guide as its motion support. A high-precision ball screw is connected to the linear mold through a nut seat. The servo motor is connected to the ball screw through a synchronous belt to drive the linear mold movement and positioning, effectively ensuring the linear mold's motion rigidity and positioning accuracy; the servo motor is directly connected to a low-backlash planetary reducer to drive the circular mold to rotate, ensuring high-precision support for the circular mold.
[0048] 3. The servo motors of the circular mold and the linear mold have a synchronous axis function to ensure the synchronization of the linear mold and the circular mold.
[0049] 4. The workpiece positioning mechanism and the double-station orientation / return mechanism avoid the thin-walled parts at the ends of the part forming parts, thus avoiding damage to the thin-walled parts of special-shaped parts and improving the processing yield.
[0050] 5. Through the cooperation of the scanning detection mechanism and the double-station orientation / return mechanism, the rapid manual orientation of the blank workpiece is promoted, which effectively solves the problem of poor consistency in the forming processing of special-shaped parts, ensures the forming consistency of the parts, and meets the design requirements.

[0131] Example 2
[0132] On the basis of Example 1, the method for forming and processing a special-shaped part using the device described in Example 1 includes the following steps:
[0133] (1) Loading and positioning of workpieces: First, manually place the blank workpiece 29 into the loading box 10 of the loading mechanism 65, start the wheel assembly, and the ratchet push cylinder 3 drives the ratchet 7 to rotate the ratchet 5, so that the blank workpiece 29 falls into the groove wheel 9 in the groove wheel seat 2. After the groove wheel 9 rotates, the blank workpiece 29 enters the loading channel, and the push cylinder 4 is started to push the blank workpiece 29 out of the loading channel to the workpiece positioning mechanism 64;
[0134] (2) Workpiece positioning: The contoured positioning block 20 of the workpiece positioning mechanism 64 clamps the blank workpiece 29, and the axial positioning assembly, the center positioning assembly, and the locking assembly perform axial positioning and center positioning on the blank workpiece 29, and then the positioned blank workpiece 29 is transferred to the scanning and detection mechanism 63 via the first synchronous belt 22;

[0136] (4) Workpiece orientation: After the number characters on the blank workpiece 29 are identified, the dual-station orientation / return mechanism 66 switches to the grasping station and drives the three-claw cylinder 31 to grasp the blank workpiece 29. The three-claw cylinder 31 is rotated by the synchronous motor through the second synchronous belt 35 so that the number characters on the blank workpiece 29 are located outside the forming surface.
[0137] (5) Roll extrusion molding: The blank workpiece 29 after rotational positioning is moved into the linear die 52 of the molding mechanism 67, and the blank workpiece 29 is clamped and positioned by the clamping cylinder 50. The blank workpiece 29 is roll extruded according to the preset position. The circular die 47 rotates axially, and the linear die 52 moves on the guide rail at the same operating speed as the circular die 47 to roll extrusion the blank workpiece 29. After the blank workpiece 29 is formed, the circular die 47 and the linear die 52 return to zero point, and the clamping cylinder 50 is released.
[0138] (6) Workpiece unloading: The double-station orientation / return mechanism 66 is switched to the return station. Under the action of the return cylinder 37, the formed workpiece is pushed out of the mold and falls onto the slide 68 of the unloading mechanism 69. It then passes through the slide 68 and falls onto the conveyor belt 59. Finally, the operator removes the formed workpiece from the conveyor belt 59 and places it in a turnover box.

[0143] The first notch 80 and the second notch 81 are used to cooperate with the installation of the second connecting plate 48 and the clamping cylinder 50, and do not affect the axial rotation of the circular mold 47.

[0147] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.
[0148] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.
[0149] The above is an exemplary description of the present invention. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by other skilled in the art without expending creative labor falls within the scope of protection of the present invention.
