It is logical；The rear end of the heading mould has the protrusion for squeezing flexible mould, and the compressive plane of the protrusion is provided with and to the draw
The compatible third recessed portion in part end.
Further improvement lies in that: it further include post-positioning device, which is arranged in the rear of clamping, for positioning
To draw part.
Further improvement lies in that: the post-positioning device includes for supporting to the block of draw part and for driving block
The screw body of movement.
Further improvement lies in that: it further include prelocalization device, which is arranged in the front of clamping, for positioning
To draw part.
The utility model has the beneficial effects that:
1, guarantee drawing size and circularity, homogeneity of product is high, being capable of guaranteed quality.
2, the double muscle of drum, noise are small.
3, the draw is shaped by material extrusion mode, rather than hard forming, pipe will not rupture.
4, in same set of equipment, it can be used for the draw of different pipe fittings.
5, the moulding process that the utility model reduces pipe fitting end diameter, pipe enter deformed area in responsive to axial force,
The necking plastic deformation tangentially shunk is generated in deformed area, subsequently into stable region, is ultimately formed the end diameter of diminution, is managed
Son will not rupture.Novel device and mold make production efficiency improve 100%, and manufacture difficulty and cost substantially reduce, draw product
100% qualification
