The invention relates to linear friction welding equipment. The equipment comprises a stand column, a vibration sliding table, a top forging sliding seat, a top forging oil cylinder and a balance oilcylinder, wherein the vibration sliding table can linearly move along the stand column, a vibration clamp is arranged on the vibration sliding table, a top forging clamp is arranged on the top forgingsliding seat, the top forging oil cylinder is used for generating upsetting force and transmitting the upsetting force to the top forging sliding seat, the balance oil cylinder is arranged between the stand column and the vibration sliding table, hydraulic oil in the balance oil cylinder can generate balance force and act on the vibration sliding table, and the balance force is opposite to the direction of the upsetting force. The balance force is generated through the hydraulic oil in the balance oil cylinder and acts on the vibration sliding table, and the balance force is opposite to the direction of the upsetting force, so that deformation caused by unbalanced force borne by the vibration sliding table can be weakened or even eliminated, and therefore the welding precision is improved. The linear friction welding equipment is simple and compact in structure, convenient to mount and dismount, high in welding efficiency and wide in application wide, and can carry out the friction welding on the welding surfaces with different sizes without the need for replacing the welding equipment.
Description
technical field [0001] The invention relates to the field of welding equipment, in particular to a linear friction welding equipment. Background technique [0002] Linear Friction Welding (Linear Friction Welding) is a welding technology that has developed rapidly in recent years. It is mainly used in the manufacture of engine blisks and aircraft frame beams. The welding principle is: under the action of welding pressure, the vibration of the weldment High-frequency vibration in the vertical direction, the upsetting weldment contacts the end surface of the vibrating weldment under the action of the upsetting force in the horizontal direction, and high-frequency friction occurs on the contact surface to generate heat. As the temperature rises, the contact surface material softens, Deformation, when the friction surface reaches the viscoplastic state, stop the vibration friction quickly to ensure that the vibration direction of the two weldments is aligned, and maintain the up...
