Description

Technical Field

[0001] The invention relates to the field of metallurgy, in particular to a jaw seat of a radial forging manipulator. Background Art

[0002] The 16MN diameter forging machine is equipped with two manipulators. The jaw seat is installed on the jaw arm of the manipulator. The maximum clamping torque of the jaw arm is 160KNm, the maximum clamping weight is 10 tons, the jaw clamping range is: round ∮100-800mm; square 100-570mm, and the clamping length of the forging end face is 150-450mm. In addition to clamping during production, the four jaws are usually open in a trumpet shape.

[0003] The existing jaw seat is equipped with a jaw buffer, which is mainly to make the jaw open larger outside and smaller inside after the jaw rotates and changes position, so that the operator can smoothly put the end of the forging material into the jaw. However, due to the large installation volume of the jaw buffer, when clamping a relatively curved steel billet, it is often deformed by the impact of the bent steel or the fixing bolts loosen and fall off, and the average service life is one week; once the jaw buffer fails, the jaw is in a free swinging state. Because the surface of the forging material is uneven during forging, under the action of clamping inertia, the clamping surface of the jaw will produce point contact with the surface of the forging material instead of surface contact. During the continued forging process, the contact point becomes deeper and deeper due to the clamping force and the radial shaking of the jaw when rotating, and the deepest point can reach about 15mm, resulting in quality defects. The clamped part of the end of the forging material must be cut off by 400mm, which reduces the yield rate. Summary of the invention
