Technical Field

The invention belongs to the technical field of die forging, and particularly relates to a mechanical arm clamp for die forging.

Background

The forging die is a die used in a forging process, and a raw material is plastically deformed in the forging die by an external force, thereby obtaining a part of a desired shape and size. The forging die can be divided into a hot forging die, a warm forging die and a cold forging die according to different forging temperatures, a forged piece needs to be taken out through a clamp after a grinding tool is forged, and most of the existing clamps for forging are mechanical arm clamps.

For example, application No.: CN 201920414015.0's chinese utility model patent discloses a forged arm anchor clamps of mould, including centre gripping subassembly, installation component and power component, centre gripping subassembly quantity is two, and set up respectively in installation component both sides, power component is fixed in the installation component top. Has the advantages that: the utility model discloses a compress tightly the laminating with locating piece and die forging top to fix a position the tight position of anchor clamps both sides clamp, ensure die forging both sides and press from both sides tight highly unanimous, thereby improve anchor clamps centre gripping fastness, prevent that the both sides atress is uneven to cause the die forging to drop; use the cylinder to provide centre gripping power, improve the shortcoming that the taut clamping-force of spring is not enough, improve clamping structure stability, the practicality is strong.

Based on the search for patent numbers, the defects in the prior art are combined to find that:

current arm anchor clamps are when pressing from both sides tightly, it is tight that the clamp arm is driven to press from both sides through pneumatic cylinder cooperation connecting rod drive most, but the connecting rod can produce an radian at the swing in-process, thereby make the clamp arm clamping process can fluctuate, cause the phenomenon of the reduction of clamp arm clamp surface, when the arm presss from both sides tightly, the articulated department of pressing from both sides between clamp connecting rod and the clamp arm can produce great frictional force and pulling force, influence the life of arm, the arm can swing when pressing from both sides tightly and press from both sides tightly, because the range of arm swing is limited, can only press from both sides tightly to less part when pressing from both sides tightly, three clamp arm swings simultaneously when the arm presss from both sides tightly, cause under the anomalous condition of part and press from both.
