Abstract
The utility model relates to a metal die for ball press roll sleeve casting of the molded coal equipment and cold ball press equipment, comprising a die, which is outer annulus die consisting of a plurality of circular arcs. On the inner annulus of the die is equally distributed with projections, which are sized in a regular prism, a prism frustum, a hemispheroid, a semi-ellipsoid, or a semi-drum. The convexity of each projection is smooth round arc, the horizontal and vertical row of each projection are connected by a trough. When the project is sized in a regular prism or a prism frustum, the trough between the horizontal and vertical rows of each projection is liner with wide opening and narrow bottom; when the project is sized in a hemispheroid, a semi-ellipsoid, or a semi-drum, the trough between the horizontal and vertical row of each projection is circular with wide opening and narrow bottom. The quantity of the circular arcs shall be two at least and four optimally, with the advantages of once molding, saving cost, high precision and convenient processing.
Description
Technical field
The utility model relates to a kind of ball press roll sheath casting metal die at type coal equipment, coal-pressing ball equipment.
Background technology
At present, the ball press roll sheath when casting used metal die shape single, when run into unmanageable in during high-chromium alloy wear resistant cast iron roll, often need to cast the back secondary operations, not only time-consuming but also effort, cost height and difficulty of processing are big.
Summary of the invention
The purpose of this utility model is to overcome deficiency in the prior art and a kind of one-shot forming, saving cost, precision ball press roll sheath casting metal die high and easy to process is provided.
The purpose of this utility model is achieved in that the utility model comprises mould, and the inner periphery mould that mould is made up of the multi-disc circular arc body is uniform-distribution with projection on the inner periphery of mould.Described projection be shaped as one of positive terrace with edge, terrace with edge, hemisphere, semiellipsoid, half drum body, the convex surface of each projection is level and smooth arc surface, communicates with groove between the horizontally-arranged of each projection and the vertical setting of types.When described projection was positive terrace with edge or terrace with edge, the horizontally-arranged of each projection and the groove between the vertical setting of types were the linear mouthful of narrow groove in the wide end.When described projection is hemisphere, semiellipsoid, half drum body, between the horizontally-arranged of each projection and the vertical setting of types the narrow groove in the wide end of mouth of circular arc.Described circular arc body is at least two, and the best is four.
The utlity model has one-shot forming, saving cost, precision height and advantage easy to process.
