Problems solved by technology
[0002] In the process of forging and forging, in many cases, the die to be forged is placed under the forging machine, and the plunger of the forging machine is used to reciprocate up and down. Base, when forging, the forging press forms the lower mold through the lower base. Now the commonly used ball joints between the plunger and the lower base are flat ball heads. Due to the frequent movement of the plunger rod during the forging process, the lower base The contact surface with the plunger rod will cause relatively large loss due to stress, which will affect normal production. When the loss is relatively large, the plunger will be eccentric, resulting in uneven force; When the plunger rod is eccentric, the ball head and the plunger rod need to be replaced, which is time-consuming and laborious, and the cost will be greatly increased
The plunger rod and the lower base are pressed tightly by the spherical pressure ring, so that the plunger rod and the ball head are in contact with each other to relieve the eccentric load, but the eccentric load cannot be completely eliminated. The existing spherical pressure ring is in contact with the lower part of the plunger rod The surfaces are all inclined surfaces. When an eccentric load is generated, the inclined surface will slide, resulting in insufficient contact between the plunger rod and the ball head, and the plunger rod will shake.

Embodiment Construction
[0019] see figure 1 , the forging press plunger of the present invention includes a plunger rod 1, a base 2, a ball head 3, a spherical pressure ring 4, a bolt 5, and a positioning ring 6; the ball head 3 is arranged on the base 2, and is fixedly connected with the base 2 Together, the connection method can be any fixed connection method, such as bolt connection, pin connection, etc.; the contact surface of the plunger rod 1 and the ball head 3 is also changed to a concave spherical surface accordingly. When the movement of the plug rod 1 drives the base 2 to forge the object, when the base 2 receives an impulse force, the corresponding plunger rod 1 will also receive a reaction force. At the same time, the eccentric load can also be prevented. Under long-term action, the wear between the two can also be reduced through the structure of the spherical surface, so that the plunger rod 1 is less likely to be offset and affects the forging quality.

The invention provides a forging press plunger. The forging press plunger comprises a plunger rod, a base, a bulb and a spherical surface compression ring, wherein the base is connected with the head of the plunger rod; the bulb is arranged between the plunger rod and the base; the spherical surface compression ring is adaptive to a protrudent annular surface of the head of the plunger rod; the contact surface of the bulb and the plunger rod is spherical and is provided with a lubrication slot; and the spherical surface compression ring is matched with the protrudent annular cambered surface of the plunger rod. In the forging press plunger, the upper surface of the bulb is adaptive to the spherical surface of the plunger, so the eccentric load is effectively prevented.
