The stamping die is characterized in that: a positioning block is arranged at the central position of the lower template, four groups of sliding block mechanisms are arranged on the lower template, the four groups of sliding block mechanisms are symmetrically arranged by using the positioning block as a center and along two diagonal lines of the lower template, the four groups of sliding block mechanisms are provided with female die inserts, and the upper template corresponding to the central position of the lower template is provided with a core rod structure.

Description

Be used for the diel of pipe fitting pipe shaft necking down processing
Technical field
The present invention relates to the Stamping Die Technology field of pipe fitting, be specially the diel for pipe fitting pipe shaft necking down processing.
Background technology
General pipe fitting necking down processing mainly is the necking down for the pipe fitting mouth of pipe, and it directly dwindles the mouth of pipe extruding of pipe fitting by the reducing die, and it can't carry out to the pipe shaft of pipe fitting necking down processing.
Summary of the invention
For the problems referred to above, the invention provides the diel for pipe fitting pipe shaft necking down processing, it can carry out effective necking down processing to the pipe fitting pipe shaft.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern, described lower die structure comprises lower bolster, it is characterized in that: described lower bolster center is equipped with locating piece, four groups of slide block mechanisms are installed on the described lower bolster, described four groups of slide block mechanisms are installed centered by described locating piece and along two diagonal of described lower bolster are symmetrical, on described four groups of slide block mechanisms die plate insert is installed all, the corresponding described lower bolster of described cope match-plate pattern center is equipped with mandrel structure.
It is further characterized in that: described slide block mechanism comprises slide, and described slide is installed on described lower bolster, and slide block and described die plate insert are installed on the described slide, and described slide block is connected with described die plate insert; Described slide outer end is equipped with block, on described slide block and the block cover plate is installed; Described mandrel structure comprises plug, and described plug is installed on fairlead, and described fairlead is installed in the die hole at described cope match-plate pattern center; Described plug passes described fairlead and passes upper padding plate and the discharging cover that is installed on described cope match-plate pattern below; Described discharging cover is by spring and lay down screw and mount in described cope match-plate pattern; Four groups of slide block mechanism positions of the corresponding described lower bolster of described cope match-plate pattern are installed and are tiltedly carved, and the described outside of tiltedly carving is equipped with the backer.
A kind of diel for pipe fitting pipe shaft necking down processing of the present invention, the locating piece of its plug by upper die structure and lower die structure with pipe fitting vertically four groups of slide block mechanisms fixing, lower die structure promote four die plate inserts and from outer radial pipe fitting pushed the necking down moulding simultaneously, it is simple in structure, and moulding is reliable.
Description of drawings
