The current positional change between the upsetting process of the two-die forging machine is realized by the lifting movement of the punch, and the die is fixed. This type of upsetting machine requires a set of complicated structure of the cutting mechanism and the clamping mechanism, which causes the structure of the entire upsetting machine to be complicated, and the requirements for the matching between the cutting, upsetting and ejection are high, and it is difficult to achieve high speed upsetting. The debugging is particularly troublesome, as in the upsetting machine disclosed in the application number 200910193907.3.

Corresponding to the traditional multi-mode multi-crush multi-station upsetting machine, the upset forging die is horizontally arranged, and the plurality of upset forging dies are fixed, and the plurality of punches are moved in one direction only, due to 镦The forging die or the punch does not translate, and the blank can only be transferred by the movement of the clamp, and the blank is only forged once in the upset die.

Of course, there is also a forging machine for mounting a trimming die to a main mold base.

The high-speed forging machine of the above structure removes the shearing mechanism and the like in the prior art, so that the mechanism is simple, the operation is simple, and the cost of the device is reduced. However, the forging machine belongs to the equipment when the die is rotated. Therefore, the same blank is required to be subjected to multiple upsetting in the same die, and the final die does not leave a die. However, the upset deformation of the same die is limited, and therefore, the quality of the upset is poor, and it is difficult to eject at the same time.

The invention reduces the punch lifting mechanism which is high in failure rate, difficult to adjust and operate, and reduces the independent cutting mechanism and the picking mechanism by the conventional multiple punches.

The conventional upsetting forging die of the conventional multi-mode multi-crush multi-station upsetting machine is horizontally arranged, and the plurality of upset forging dies are fixed, and the plurality of punches are only moved in one direction for the squatting section, due to the upset forging die Or the punch does not shift, the clamp can only be used to transfer the blank, and the blank is only forged once in the upset die. The invention can be upset twice in the same upset die, and the deformation is large. The clamp can be eliminated, the clamp is not good for some workpieces, the conventional equipment cannot be manufactured, and the present invention can be manufactured.

In the present embodiment, when the clamp is required, the clamp provided by the present invention does not move, and only the movement of the main mold base is required. When the existing boring machine adopts the clamp, the clamp needs to move. When the clamp moves fast, some long blanks will sway, which is not so precise, and it is difficult to accurately forge. The clamp of the invention is not moving, the clamp is only clamped, does not move, and the blank does not shake. Easy to forge and precise design. The invention can be designed with clamps in some stations, some of the stations do not design the clamps, and the punches are used for the materials, and the combination can be adapted to the manufacture of different products. The transfer of the billet is forged twice at each station, with large deformation, better production process and better products.
