A track groove 5 is opened on the side of the movable support seat 4, the inner wall of the track groove 5 is in contact with one end of the positioning bolt 6, the other end of the positioning bolt 6 is installed with a positioning nut 7, the positioning bolt 6 passes through the positioning hole 8, the positioning hole 8 is opened through the bottom of the installation gantry 9, the side hydraulic rod 10 is installed through the top of the vertical part of the installation gantry 9, the end of the side hydraulic rod 10 is fixedly installed with a side positioning plate 11, the top hydraulic rod 12 is installed through the top of the installation gantry 9, and the bottom end of the top hydraulic rod 12 is fixedly connected to the top surface of the top positioning plate 13.

[0021] In this example, the electric telescopic rods 3 are symmetrically distributed with respect to the movable support seat 4, the movable support seat 4 is symmetrically distributed about the center of the forging seat 2, and the top surface of the forging seat 2 and the top surface of the movable support seat 4 are on the same horizontal plane. The above structural design can stably support the die steel, and the electric telescopic rods 3 can also conveniently control the horizontal position of the movable support seat 4.

[0022] The side view shape of the installation gantry 9 is "冂"-shaped, and the inner side bottom of the vertical part of the installation gantry 9 is in close contact with the outer side wall of the movable support seat 4. The above structural design ensures the stability of the installation gantry 9 and the installation structure thereon.

[0023] The positioning bolt 6 is slidably connected to the track groove 5. The positioning bolt 6 is symmetrically distributed about the center of the movable support seat 4. The side view shape of the track groove 5 is a "T" shape. The length of the track groove 5 is greater than 3 / 4 of the front view length of the movable support seat 4.
