[0002] With the advancement of technology, robotic arm designs are becoming increasingly ergonomic, resulting in a greater number of curved surfaces on the outer shell workpiece. If the outer shell workpiece requires punching and flanging processes on its inclined surfaces, generally speaking, a corresponding inclined surface needs to be designed in the lower mold to support the workpiece. However, due to the slope of the inclined surface, the workpiece is prone to move along the inclined direction under the action of gravity, which can easily lead to inaccurate positioning during mold closing, thereby affecting the processing quality of the workpiece.

[0036] Please see Figure 1 The present invention provides a robotic arm mold swinging and flanging mechanism 100, which includes an upper module 10, a lower module 20, a pressing component 30, a swinging component 40, and a flanging component 50. The upper module 10 is fixedly mounted on the upper mold, the lower module 20 is fixedly mounted on the lower mold, the pressing component 30 is disposed on the upper module 10, and the swinging component 40 is disposed on the lower module 20.

[0037] Please see Figure 2 The upper module 10 is provided with a stamping inclined surface 11, and there are two stamping inclined surfaces 11. The two stamping inclined surfaces 11 intersect each other. The upper module 10 is provided with a relief groove 12, which is provided on the stamping inclined surface 11.

[0038] Please see Figure 2 The number of the pressing components 30 is two, and the two pressing components 30 are respectively disposed on the left and right sides of the upper module 10. The pressing component 30 includes a pressing block 31 and a pressing telescopic rod 32 connected to the pressing block 31. The upper module 10 is provided with an installation groove and a fixing groove. The fixing groove is connected to the installation groove. The pressing telescopic rod 32 is fixedly disposed in the fixing groove. The pressing block 31 is disposed in the installation groove and can be moved up and down. The telescopic end of the pressing telescopic rod 32 abuts against the pressing block 31.

[0039] Please see Figure 2 The pressing assembly 30 also includes a baffle block 33, which is fixedly connected to the upper module 10. The outer end of the pressing block 31 is provided with a guide groove 311, and the baffle block 33 is inserted into the guide groove 311.

[0040] Please see Figure 3 and Figure 4The swing assembly 40 comprises two components, which are arranged adjacent to each other along the length of the upper module 10. Each swing assembly 40 corresponds one-to-one with the stamping inclined surface 11. Each swing assembly 40 includes a fixed block 41, a hinge shaft 42, and a swing block 43. The fixed block 41 is fixedly mounted on the lower module 20. The fixed block 41 has a hinge through hole and a groove 411 on its side. The swing block 43 is disposed within the groove 411. The outer wall of the swing block 43 has a hinge mounting hole. One end of the hinge shaft 42 passes through the hinge through hole and extends into the hinge mounting hole. The other end of the hinge shaft 42 is embedded in the hinge through hole. The swing block 43 is hinged to the fixed block 41 and can swing around the hinge shaft 42. The swing block 43 has a punched post 44 and a stamping plane 431 adapted to the stamping inclined surface 11. The punched post 44 is disposed on the stamping plane 431. The end face of the swing block 43 away from the stamping plane 431 is provided with a first inclined surface 432, a second inclined surface 433, and an arc surface 434. The arc surface 434 is disposed between the first inclined surface 432 and the second inclined surface 433. The fixing block 41 is provided with an abutment plane. The arc surface 434 facilitates the swing of the swing block 43. The swing block 43 is provided with a pressure groove 435. One pressure block 31 can simultaneously engage with the pressure grooves 435 of two adjacent swing blocks 43, thereby pressing both swing blocks 43 simultaneously onto the fixing block 41.

[0041] Please see Figure 3 and Figure 4 The flanging assembly 50 includes a flanging stamping block 51 and a flanging pad block 52. The flanging stamping block 51 is fixedly disposed on the upper module 10. There are two flanging stamping blocks 51, one of which is disposed on one of the stamping inclined surfaces 11, and the two flanging stamping blocks 51 are disposed adjacent to each other. The flanging pad block 52 is connected to the lower module 20 and is disposed between the two flanging stamping blocks 51.

[0042] The robotic arm mold swinging and flanging mechanism 100 also includes a reset telescopic rod, which is fixedly installed on the lower module 20, and the telescopic end of the reset telescopic rod abuts against the swing block 43.

[0043] The working principle of the manipulator mold swinging and flanging mechanism 100 described in this embodiment is as follows: The operator places the workpiece on the swing block 43. At this time, the second inclined surface 433 of the swing block 43 abuts against the contact plane. The stamping plane 431 is located on the horizontal plane. This can effectively avoid the phenomenon that the workpiece is easily moved along the inclined direction of the inclined surface when it is placed in the lower mold due to gravity, which leads to inaccurate positioning. This effectively improves the processing quality. During the pressing process, the upper die moves downward along with the upper module 10 and the pressing assembly 30. The pressing block 31 is engaged in the pressing groove 435 of the two adjacent swing blocks 43, causing the swing blocks 43 to swing inward to press the swing blocks 43 onto the fixed block 41. At this time, the first inclined surface 432 of the swing block 43 abuts against the abutting plane. The upper module 10 continues to press towards the swing block 43. The punching post 44 passes through the workpiece and extends into the relief groove 12 to complete the punching. The flanging punching block 51 cooperates with the flanging pad block 52 to complete the flanging.

[0044] When the mold is opened, the pressure block 31 leaves the pressure groove 435. Under the action of gravity and the reset telescopic rod, the swing block 43 moves the workpiece that has completed punching and flanging outward to reset.

[0045] The beneficial effects of this utility model are as follows: With the cooperation of the upper module 10, lower module 20, pressing component 30, swing component 40 and flanging component 50, the phenomenon of inaccurate positioning caused by the inclined surface of the traditional lower mold being set can be effectively avoided. The workpiece is easily moved along the inclined direction of the inclined surface under the action of gravity when it is placed in the lower mold, thereby effectively improving the processing quality.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
