Abstract
The utility model provides a flaring mould of a pipe fitting, which comprises a mould core and a flaring expanding block, wherein the mould core is penetrated through the middle of the flaring expanding block. The flaring mould is characterized in that one end of the mould core is in the shape of cone, and the inner surface of the end of the flaring expanding block is provided with a cone which corresponds to the mould core. A piston of a flaring machine drives the flaring expanding block to move to and fro along the mould core, i.e. the flaring expanding block is shrunken and the machined metal pipe fitting is sheathed out of the flaring expanding block when the piston is withdrew; and the flaring expanding block moves to be expanded along the cone-shaped mould core and the port of the metal pipe fitting is cold extruded and flared to be shaped when the piston is pushed outwards. The flaring mould has the characteristics of being simple in structure, convenient in operation, and high in work efficiency.
Description
Technical field
The utility model relates to cold extrusion die, specifically is a kind of pipe fitting enlarging mould that is applicable to that the cold extrusion enlarging of metal tube termination is shaped.
Background technology
The technology of port enlarging is often adopted in connection between the metal tube, and to realize the socket connection mode between the metal tube, hot expansion mode is adopted in the enlarging of metal tube port usually in the prior art, needs heater, exists low, the defect of high cost of efficient.
Summary of the invention
The purpose of this utility model is to propose a kind of pipe fitting enlarging mould that is applicable to that metal tube port cold extrusion enlarging is shaped.
The purpose of this utility model is achieved in that a kind of pipe fitting enlarging mould of the present utility model, it comprises core rod and the enlarging piece that rises, core rod is set in the rise centre of piece of enlarging, it is characterized in that an end of core rod is tapered, and the rise end inner surface of piece of enlarging has the taper corresponding with core rod.
Pipe fitting enlarging mould of the present utility model, driving the enlarging piece that rises by the piston of pipe-expanding machine moves back and forth along core rod, when piston is regained, the enlarging piece that rises is in contraction state, the metal tube of processing is enclosed within enlarging to rise outside the piece, when piston was released, the enlarging piece that rises moved along the taper core rod and opens, and the port cold extrusion enlarging of metal tube is shaped.The utlity model has characteristics simple in structure, easy to operate, high efficiency.
