Subdivision method and fixture for barrel body part

Abstract

The invention discloses a subdivision method and fixture for a barrel body part, and belongs to the field of fixtures. The barrel body part comprises a barrel body, wherein openings are formed in thetwo ends of the barrel body separately. The subdivision fixture comprises a vertical plate, a first limit support mechanism and a transversal plate, wherein the vertical plate is provided with an arc-shaped opening; the arc-shaped opening is matched with the outer wall of the barrel body, and the maximum height of the arc-shaped opening is less than the radius of the cross section of the barrel body; the first limit support mechanism comprises a first inclined support arm, a first horizontal suspension arm and a first limit component; one end of the first inclined support arm is fixed to the vertical plate; the other end of the first inclined support arm stretches out, is opposite to the arc-shaped opening, and is fixedly connected with one end of the first horizontal suspension arm; the first horizontal suspension arm is vertical to the plane where the arc-shaped opening is formed, and the projection of the first horizontal suspension arm on the plane where the arc-shaped opening is formed is located in the arc-shaped opening; the other end of the first horizontal suspension arm is fixedly connected with the transversal plate and used for stretching into the opening in one end ofthe barrel body; and the transversal plate is used for being clamped onto the inner wall of the opening in one end of the barrel body.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a method for dissecting cylinder parts and the tooling. Background technique [0002] Cylinder parts are generally rolled from high-strength alloy steel materials. At present, when using flame cutting to split it into two half rings, the splitting method includes: first place and fix the cylinder part horizontally to prevent overturning, and then use a flame gun to split directly in a free state. Among them, One split line is at the butt weld of the cylinder body, and the other split line is symmetrical to it. Since the cylinder part is rolled, there is a large internal stress inside. The result of such a split will cause the stress to be released freely, resulting in large deformation, which will affect the subsequent assembly size of the part. Contents of the invention [0003] Embodiments of the present invention provide a method and tooling for dissecting cylinder parts, which can ...
