Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1-2, the forming device for the arc rod of the top cover of the passenger car in the embodiment includes a frame 1, a rotating platform 3 erected on the frame 1 and rotationally moving along an arc platform 2, an inner arc template 4 arranged on the rotating platform 3, an eccentric locking assembly arranged at an interval at the tail end side of the inner arc template 4, an inner groove 41 arranged at the front end of the inner arc template 4 and having a side opening for accommodating a piece to be bent (not shown in the figure), and a pressing wheel 5 arranged on the surface of the arc platform 2, located outside the inner groove 41, and correspondingly matched with the piece to be bent.

The top fixed mounting of frame 1 has arc platform 2, and the corresponding laminating setting of revolving stage 3 is at the inner arc edge of arc platform 2.

The side of the inner arc template 4 is provided with a plurality of reinforcing ribs 42, and the surface of the inner groove 41 is provided with a plurality of reinforcing ribs 42.

The arc inner angle of the inner arc template 4 is arranged away from the pinch roller 5.

The eccentric locking assembly comprises a rotating shaft 6 coupled with the rotating platform 3 and a pressure rod 61 sleeved on the rotating shaft 6. The pressing rod 61 and the inner arc template 4 correspondingly clamp the piece to be bent, and the rotating pressing rod 61 presses the piece to be bent to be embedded into the inner groove 41 in place.
