To the feeding and pushing assembly 5 on the forging station 1, the forging station 1 is provided with an elastic positioning device 6 for positioning the forging position of the blank, the forging station 1 is provided with a forging discharge hole 7, the shape of the forging discharge hole 7 is the front view profile shape of the finished product after forging, a first connecting rod assembly 8 is provided between the lower forging assembly 2 and the feeding and pushing assembly 5, and a second connecting rod assembly 9 is provided between the feeding and pushing assembly 5 and the separate upper pressing assembly 3;

[0030] The cut blank is shaped in advance and subjected to high temperature treatment to forging temperature, and the high temperature treated metal blank is placed in the upper spring pressure type workpiece preparation bin 4 to be stacked and ready for loading;

[0031] During the upward reset of the downward forging assembly 2, the first connecting rod assembly 8 drives the loading and pushing assembly 5 to push the top first blank 100 in the upper spring-pressed workpiece preparation bin 4 forward and to the position of the forging station 1;

[0032] At this time, the downward forging assembly 2 moves downward to forge the first blank 100. During the downward movement, the loading and pushing assembly 5 is driven to retreat through the first connecting rod assembly 8. When the loading and pushing assembly 5 retreats to the outermost position, the subsequent blank 200 moves upward to align with the next pushing height of the loading and pushing assembly 5.

[0033] During the backward movement of the feeding and pushing assembly 5, the second connecting rod assembly 9 will also drive the separate upper pressing assembly 3 at the bottom to move upward, and cooperate with the downward movement of the lower pressing forging assembly 2 to forge and press the metal blank in the middle. After the shape of the metal blank is pressed, it has the same contour as the forging and forming discharge hole 7. At this time, the lower pressing forging assembly 2 is reset and moved upward, and the separate upper pressing assembly 3 is reset and moved downward; the separate upper pressing assembly 3 can separate the surface and the lower surface of the metal blank to prevent adhesion, so that the next time the metal blank is loaded, the finished product can be pushed to the forging and forming discharge hole 7 for unloading.

[0034] When the downward forging assembly 2 is reset upward, the loading and pushing assembly 5 can push the subsequent blank 200 forward and press the first blank 100 after forming to the forging discharge hole 7 to complete the unloading, and the subsequent blank 200 is automatically positioned to the forging station 1 for the next forging process.

[0038] The convex V-shaped platform 301 is divided into three parts: the separation forming surfaces 306 on both sides and the top position of the convex V-shaped platform 301 in the middle. The top position of the convex V-shaped platform 301 is used to limit the downward movement of the separation forming surface 306 to drive the first blank 100 to move downward, so that the separation forming surfaces 306 on both sides can well complete the separation of the lower surface of the first blank 100, so that the subsequent subsequent blank 200 can better push the first blank 100 to complete unloading.
