Technical field
The utility model relates to by a kind of device of press equipment to elongated extrusion of thin-wall pipe moulding, relates in particular to elongated light-wall pipe by after expand tube, the device of draw moulding on the expand tube basis.
Background technology
Sometimes need elongated light-wall pipe as requested through overexpansion or compression forming in elongated light-wall pipe processing, all machine-shaping on forcing press of elongated light-wall pipe breathing moulding, at first the expand tube axle the thin-walled materials in the tube swell the regulation requirement, then a part that swells is dwindled the physical dimension that is molded into regulation by necking die, by expand tube axle and necking die exemplar that meets product requirement of a materials in the tube moulding, wherein materials in the tube should be not crooked in plastic deformation, breach not, the process plastic deformation is good.For elongated light-wall pipe processing, because material walls is thin, does not slightly note and will damage, produce breach etc., therefore need special-purpose shaped device.
Summary of the invention
the purpose of this utility model just is to provide a kind of elongated extrusion of thin-wall pipe shaped device, extrusion forming device described in the utility model comprises ring flange, the expand tube supporting base, the expand tube axle, draw supporting base, draw film, bolster, ring flange is a circular disk with holes, be placed on press bench, play the fixedly effect of expand tube supporting base and draw supporting base, the outside of expand tube supporting base and draw supporting base all is provided with the Step Shaft part, the hole of this part and ring flange is connected as a single entity, inside is equipped with the hole that holds elongated light-wall pipe, in processing, when expand tube, elongated light-wall pipe to be processed is placed in the expand tube supporting base, play stabilization, make elongated light-wall pipe steady when expand tube, during the draw, elongated light-wall pipe is placed in the endoporus of draw supporting base, play balanced action, stressed even when making the elongated light-wall pipe draw,
described expand tube axle is Step Shaft thick between the detail of two, the axle two ends change to major diameter from minor diameter and are provided with the transition conical surface, conical surface geometric angle Kong Zai processed＜=25 ° of scopes, preferably less than 25 °, by axle, elongated tubular is swollen, extruding reduces extrusion friction power in the way, alleviate machining deformation, the expand tube axle is the basis of elongated tubular forming shape, the size of elongated thin-wall pipe shaping, shape is directly affected by the expand tube axle all, expand tube adds man-hour, elongated light-wall pipe one end is placed in expand tube supporting base hole, another stomidium interpolation enters the expand tube axle, complete the expand tube moulding by press equipment, then withdraw from the expand tube axle from formed pipe, the expand tube axle is not greater than 1/4 with the whole contact-making surface of elongated light-wall pipe to be processed at work, generally most suitable in 1/4 left and right, can make so elongated light-wall pipe capable of reducing friction resistance in moulding, stablize the expand tube moulding,
The axle co-controlling is propped up and held to draw size, the shape of elongated light-wall pipe by draw film, described its endoporus of draw mould is cone structure, bolster is also a kind of step-like cylindrical part, when the elongated light-wall pipe draw, microcephaly's one end of bolster is inserted in the hole of draw supporting base, the draw mould of packing on draw supporting base, one end of draw mould coordinates with the stepped hole of draw supporting base, the elongated light-wall pipe that then will swell is packed in bolster, with elongated light-wall pipe one end of forcing press extruding, elongated light-wall pipe swells part by draw mould, shrinks moulding.
Just an elongated light-wall pipe can be arrived the draw again via expand tube by above mould, become at last finished product.
This practicality newly owing to adopting above technical scheme, makes it to compare with existing other technology, has simple in structure, easy to operate, can process smoothly the elongated thin-walled breathing of all size part that meets the technical quality requirement on press device, improve productivity effect, also improve machining accuracy.
