Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A pulley bracket shaping device is shown in figures 1 to 3 and comprises a press machine 1, wherein a shaping lower die 2 fixed on the press machine 1 is arranged on the press machine 1, and a shaping upper die 3 matched with the shaping lower die 2 is arranged above the shaping lower die 2; the shaping lower die 2 comprises a base 4, and a positioning block 5 is arranged in the middle of the base 4; two sides of the positioning block 5 are provided with symmetrical fixing blocks 6, and the fixing blocks 6 are parallel to the positioning block 5; each fixed block 6 is provided with a pushing block 7 which can move towards the positioning block 5 and can automatically reset, and the pushing block 7 is parallel to the positioning block 5; a driving block 8 is arranged at the position, corresponding to each pushing block 7, on the shaping upper die 3, and the driving block 8 can drive the pushing blocks 7 to move towards the positioning blocks 5;
