Jaw seat of radial forging manipulator

Abstract

The invention provides a jaw seat of a radial forging manipulator, and relates to the field of metallurgy. The jaw seat comprises a jaw seat body, a pin shaft hole is formed in a jaw, the jaw seat body is hinged to a clamp arm of the manipulator at the pin shaft hole through a pin shaft, and first pin holes are formed in the two ends of the jaw seat body; the jaw is included and is connected with the jaw seat body; and a fixing mechanism is included and is used for fixing the jaw and the jaw seat body through a pin, wherein the distance between the circle center of the pin shaft hole and the center of the stress surface of the jaw seat body in the length direction of the jaw is 20 mm-40 mm, in the steel clamping process of the jaw, the point clamping situation cannot occur, the clamping surface of the jaw makes good contact with the surface of a forged material, and the clamping damage probability of the jaw is greatly reduced.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a jaw seat of a radial forging manipulator. Background technique [0002] The 16MN radial forging machine is equipped with two manipulators. The jaw base is installed on the clamp arm of the manipulator, the maximum clamping torque of the clamp arm is 160KNm, the maximum clamping weight is 10 tons, the clamping range of the jaws: round ∮ 100-800mm; square 100-570mm, the clamping length of the forged material end face 150-450mm. Except for the jaws being clamped during the production process, the daily four jaws are trumpet-shaped openings. [0003] The existing jaw seat is equipped with a jaw buffer, mainly to allow the jaw to be in a state where the outer opening is large and the inner opening is small after the jaw rotates and the position changes, so that the operation function can smoothly include the end of the forged material into the jaw . However, due to the large installati...

Problems solved by technology

However, due to the large installation volume of the jaw buffer, when clamping a curved steel billet, it is often deformed by the impact of the bent steel or the fixing bolts are loose and fall off, and the average service life is one week; once the jaw buffer fails, the jaw is in a free state. In the swing 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 have point contact with the surface of the forging material instead of surface contact

During the continuous forging process, due to the clamping force and the radial shaking when the jaws rotate, the contact point becomes deeper and deeper, and the deepest point can reach about 15mm, resulting in quality defects, and the pinched part at the end of the forging must be cut off 400mm, reduced yield
