The utility model solves the technical scheme that its technical problem adopts: a kind of corrugated pipe orifice rolling mould, comprise ripple head axle and a ripple head 12 thereof that can stretch into body stomidium, it is characterized in that, described ripple head axle coordinates two shape sizes consistent, symmetrical, can separate involutory clamping piece 1, to the involutory die body clamping pipe fitting being combined into, rolling rolled tube oral area external drum ripple on bed by described clamping piece; Clamping piece 1 inwall is shaped with the involutory locating hole 9 of clamping body, and the end of described involutory locating hole is shaped with the circular arc annular groove identical with ripple head 12 external drum flange shape.
Involutory clamping body clamping is rolling in a matrix 7 chucks, body is by involutory locating hole, end face is close to the lower surface of spacing back-up ring 2, the connected ripple head 12 in ripple head axle 4 one end gos deep into conduit aperture, one end is by rolling a main shaft 6 eccentric inner holes, be locked in main shaft 6 bias, main shaft rotarily drives ripple head axle 4 ripple head 12 eccentric rotary, quick rolling forming ripple in clamping piece circular arc annular groove.
The utility model has following beneficial effect than prior art.
The utility model is connected in the matrix rolling on bed by upper lower clamp formwork piece, ripple head axle is contained in rolls in adjustable eccentric orfice of a main shaft, make eccentric head rotation by cam mechanism, the reduction gearing of rolling on bed, utilize the ripple head 12 of eccentric rotary in clamping piece circular arc annular groove, roll forming pipe end ripple fast, efficiency is high, Functionality, quality and appealing design, simple to operation, solve long pipe fittings, the limited problem of major diameter guiding-tube bend moulding pipe end ripple.The whole process time is short, only needs within ten seconds, can process at one time, and manufacturing cost is only 1/20 of cold stirrup method.
The utility model is applicable to the pipe fitting large with diameter, body is grown.

Detailed description of the invention
Consult Fig. 1-Fig. 4.A kind of corrugated pipe orifice rolling mould that the utility model provides, comprise ripple head axle and a ripple head 12 thereof that can stretch into body stomidium, described ripple head axle coordinates two shape sizes consistent, symmetrical, can separate involutory clamping piece 1, to the involutory clamping body clamping pipe fitting being combined into, rolling rolled tube oral area external drum ripple on bed by described clamping piece; Clamping piece 1 inwall is shaped with the involutory locating hole 9 of clamping body, and the end of described involutory locating hole is shaped with the circular arc annular groove identical with ripple head 12 external drum flange shape.Clamping piece 1 is symmetrical, consistent by two shape sizes, and symmetrical centre axial plane can separate involutory module composition.Involutory clamping body central port is shaped with two sagging stepped holes, and the sagging stepped hole that is positioned at port below is the locating hole of positioning limit back-up ring 2, is to be shaped with clamping body under it, the involutory locating hole 9 of conduit 8.In involutory locating hole 9 upper port, be shaped with the circular arc annular groove 10 identical with ripple head 12 external drum flange shape sizes.Circular arc annular groove 10 port tops are shaped with the stepped hole 11 that sink, and step surface is provided with the spacing back-up ring 2 connecting firmly by screw 3.Two screw threads for fastening holes of attachment screw 3 are positioned on the step surface of the involutory clamping body of clamping piece.Involutory clamping body clamping is rolling in a matrix 7 chucks, and conduit 8 is by involutory locating hole 9, and end face is close to the lower surface of spacing back-up ring 2.The connected ripple head 12 in ripple head axle 4 one end gos deep into conduit aperture, and one end, by rolling a main shaft 6 eccentric inner holes, is locked in main shaft 6 eccentric orfices.Ripple head axle 4 axle heads are provided with rubber back-up ring 5.Main shaft rotarily drives ripple head axle 4 ripple head 12 eccentric rotary, quick rolling forming ripple in clamping piece circular arc annular groove.
