For the convenience of understanding the bowl head forming machine provided by the embodiment of the present invention, the following will explain the working principle in detail with reference to fig. 2 and 3.
As shown in fig. 2, a blank tube is first placed in the impression of the bending die 2. The indent comprises a first indent 24 and a second indent 25 rotatably connected to the frame 1, respectively, as shown in fig. 2, the middle portions of the first indent 24 and the second indent 25 being rotatably connected to the frame 1, so that the first indent 24 and the second indent 25 can rotate relative to the frame 1. In order to ensure the stability of the blank pipe when being pressed down, the end parts of the first pressing groove 24 and the second pressing groove 25 are respectively provided with a mold core, and after the blank pipe is placed, the two mold cores are inserted into the blank pipe and clamp the blank pipe. Specifically, the mold core is a third driving hydraulic cylinder 26 fixed on the first pressure groove 24 or the second pressure groove 25, and a piston rod of the third driving hydraulic cylinder is inserted into the blank pipe. The blank tube can be clamped by extending the piston rod of the third driving hydraulic cylinder 26, so that the blank tube is prevented from shaking during bending.
After the blank tube is pressed, as shown in fig. 2, the downward pressing drive device 3 drives the die wheel 21 and the downward pressing die block in the bending die 2 to move downward. First, the first driving hydraulic cylinder 31 drives the T-shaped base 33 to move downward until the first and second press blocks 22 and 23 contact the blank pipe, and as shown in fig. 1 and 2, when the first and second press blocks 22 and 23 are in a horizontal state, the bottom surfaces of the first and second press blocks 22 and 23 and the lowest point of the die wheel 21 are located on the same horizontal plane. When the pressing modules are arranged, one ends of the first pressing module 22 and the second pressing module 23 are respectively and rotatably connected with the die wheel 21, and the other ends of the first pressing module 22 and the second pressing module 23 are respectively and rotatably connected with the adjusting seat 34 through the connecting rod.
