[0047] The forming plate 4 and the insert rod 9 are connected by threaded fitting.
[0048] The working principle of this embodiment:
[0049] During assembly, first pull the support rod 5 out of the base 2 by a corresponding length to ensure that the distance between the workpiece 100 to be processed and the curved surface of the forming plate 4 can be adjusted to a suitable distance later. Place the corresponding forming plate 4 into the positioning groove 3, and pass one end of the insertion rod 9 through the first through hole 10 and screw it to the forming plate 4 to fix it. Then, place the positioning groove 3 together with the forming plate 4 on the side wall of the base 2, and pass the other end of the insertion rod 9 through the insertion hole 11 of the base 2 and insert it into the mouth of the rotating drum 12. Then, the protrusion 16 on the insertion rod 9 can enter the groove 15 through the guide port 17. As the insertion rod 9 moves axially, the protrusion 16 will continuously rub and squeeze the groove wall of the axially spiral linear groove 15, forcing the rotating drum 12 to rotate unidirectionally to drive the first rotating disk 13 to rotate. The first rotating disk 13 The movable ring 14 interacts with the movable ring 14 through threads, and under the limiting action of the limiting block 18 and the limiting groove 19, the movable ring 14 moves in the axial direction of the first turntable 13 toward the direction close to the workpiece 100, thereby driving the pressure block 23 to move synchronously and disengage from the inclined block 22. The rocker arm 21 is deflected and tilted from the initial state of being parallel to the axial direction of the rotating drum 12 under the restoring action of the coil spring elastic force, so that the first clamping rod 24 is clamped into the first clamping hole 25, so as to lock the position of the insertion rod 9 after being inserted into the rotating drum 12, and realize the locking and fixation of the forming plate 4 in the positioning groove 3 and the positioning groove 3 on the base 2.
[0050] In addition, the rotation of the first turntable 13 can also drive the second turntable 26 to rotate, so that the arc groove 261 on the second turntable 26 rubs and squeezes the limit rod 28, and under the limiting action of the radial groove 271, the limit rod 28 moves centrifugally in the radial direction of the second turntable 26, so as to drive the second clamping rod 31 to be clamped into the corresponding second clamping hole 32 through the first connecting rod 29 and the second connecting rod 30, so as to lock and fix the position of the support rod 5 after the pull-out length is adjusted.
[0051] After assembly, the workpiece 100 is placed on the two support rods 5 and positioned by the clamping block 6 , and then the hydraulic rod of the hydraulic cylinder 7 is used to drive the hydraulic cylinder 7 to perform press bending and forming operations on the workpiece 100 .
