Detailed Description

The utility model is further described below with reference to fig. 1 to 2.

A shaping device of a thin and long forging piece 10 comprises an upper base 1, an upper workbench 5 and a lower workbench 6 which are sequentially arranged from top to bottom; the two ends of the upright post 4 are respectively fixedly connected with the upper base 1 and the lower workbench 6, and play a role in supporting the upper base 1 and the lower workbench 6. The upright 4 penetrates the upper table 5, and the upper table 5 moves up and down along the upright 4 in the vertical direction. The upper die 3 and the lower die are respectively arranged on the lower bottom surface of the upper workbench 5 and the upper bottom top surface of the lower workbench 6;

the upper die 3 and the lower die are respectively provided with a burr letting groove 17 with corresponding positions, two opposite sides of the upper die 3 are respectively provided with a burr letting groove 17, and the burr letting grooves 17 are rectangular;

the lower die is provided with a guide post 7, and the upper die 3 is provided with a guide post cavity corresponding to the guide post 7 in position; the upper die 3 is connected with a pressing device, the forging 10 is placed on the lower die, the pressing device drives the upper die 3 to move towards the lower die, and the guide pillar 7 can press and shape the forging 10 after being led into the cavity of the guide pillar 7.
