In this embodiment, specifically: the blank is placed in the first station 5 of the hot die forging press, and the blank is flattened by the first station 5 of the hot die forging press.
In this embodiment, specifically: the second station upper die 61 is located above the second station bottom die 62, the bottom of the second station upper die 61 and the top of the second station bottom die 62 are provided with pre-forging grooves, and the second station 6 of the hot die forging press is used for pre-forging a product.

Working principle or structural principle, when using:
s1, blanking: the selected raw material is a bar, and a circular saw or a sawing machine is used for blanking according to the length;
s2, heating: heating to 1150-1200 ℃ by using an intermediate frequency furnace;
s3, beating flat: flattening is carried out on a first station 5 of a 1300T hot die forging press, the blank is flattened to a certain height, the specific height value is determined according to a pre-forging cavity, and the flattened blank cannot greatly shake forwards, backwards, leftwards and rightwards when placed into a pre-forging lower die, so that a qualitative positioning effect is achieved;
s4, preforging: the pre-forging is performed at a second station 6 of the 1300T hot die forging press. Because the forging 1 is formed at one time, the middle part of the forging 1 is easy to fold and the sharp corners at two ends are easy to be filled, the forging 1 without folding can be forged by adding one or more than one preforming, and the service life of the die can be prolonged;
s5, precision forging: performing precision forging on a third station 7 of a 1300T hot die forging press to obtain a forged piece 1 with flash and punching connecting skin, and meeting the requirement of the outline size;
s6, trimming: finish forging is carried out at the fourth station 8 of the 1300T hot die forging press. Considering that the datum plane 2 of the forge piece has flatness, the datum plane 2 is used as a trimming receiving surface, which is beneficial to ensuring the flatness of the forge piece 1, but the lower side of some forge pieces 1 is irregular, so that the trimming can fall quickly, the lower side of the forge piece 1 is irregular in shape, the stress area is small, the forge piece is easy to be damaged, and the forge piece is arranged on a non-machining surface. Because the existing die carrier is used for trimming, the equipment space is limited, and a sand table or an elastic tray cannot be placed through the lower side, so that the anti-collision auxiliary tool 82 is designed. The diameter of the upper surface of the anti-collision auxiliary tool 82 is matched with the diameter of the groove surface 3 of the forging 1, and when the forging 1 falls off after trimming, the groove surface 3 is firstly contacted with the anti-collision auxiliary tool 82 before the non-machining surface is contacted with the lower bottom surface. The groove surface 3 is a machined surface, and the groove surface 3 is large relative to other non-machined surfaces, so that the groove surface is slightly damaged and can be removed through subsequent machining. The anti-collision auxiliary tool 82 is fixed on the trimming lower die fixing seat 81 through a link block 83. After the edge of the forging 1 falls, a stream of instant strong airflow is blown out from the air pipe 84 to blow the forging 1 to the rear slideway;
after the problem of edge cutting damage is solved, edge cutting, beating, pre-forging and finish forging can be completed on a 1300T four-station hot die forging press together, and the edge cutting on a punch press is not needed independently, so that the production efficiency can be effectively improved, and the energy consumption can be reduced;
s7, punching: the punching is done on a 150T punch press 9. And during punching, the reference surface 2 of the forging 1 is downward and placed in a lower punching die. Different from the traditional form, the discharging insert 98 with the diameter equivalent to that of the groove surface 3 of the forging 1 is added on the discharging plate 97, so that the non-machining surface of the forging 1 is prevented from directly colliding with the discharging plate 97 to cause collision damage to the non-machining surface during discharging.
In addition, in order to ensure the flatness of the reference surface 2, during punching, before a punching punch contacts with the connecting sheet, the unloading insert 98 firstly contacts with the forge piece 1, the spring 96 is compressed along with the continuous work of the punch press, and a part of moment unloading plate 97 is transmitted to the unloading insert 98, so that the unloading insert 98 can provide a pre-pressure for the groove surface 3 of the forge piece 1 before the punch contacts with the connecting sheet, and the reference surface 2 of the forge piece 1 is prevented from deforming when the forge piece 1 punches; after the punching is finished, the pressure on the groove surface 3 of the forging 1 reaches the maximum, so that the thermal shaping effect can be achieved, and the flatness of the reference surface 2 is further ensured. In addition, a first limiting column 99 and a second limiting column 910 are arranged at the left end and the right end, so that the unloading insert 98 is prevented from excessively crushing the forging 1, the forging cannot be removed by machining, and the product quality is not affected. The heights of the first restraint post 99 and the second restraint post 910 are determined according to the lower tolerance of the thickness of the forging 1. In addition to serving to link the stripper plate 97 to the position of the limiting spring 96, the guide post 95 also needs to be well matched with the punch holder 91 to serve as a guide.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
