The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail.
As shown in Figure 2, forming apparatus for forming pipe end of the present invention, comprise: die holder 8, expand tube mould and base 1, what base 1 was provided with two removing from moulds promotes mainly oil cylinder 2 and trip holder 3, the top of trip holder 3 is provided with clamping cylinder 4, the back piston bar of promoting mainly oil cylinder 2 is provided with stop nut 5, the secondary piston bar of promoting mainly oil cylinder 2 is provided with mount pad 6, mount pad 6 is provided with mounting flange 7, mounting flange 7 is provided with expand tube mandrel 15, mounting flange 7 links to each other with carrying bolt 11 in being located in die holder 8, be set with axle spring 12 on the carrying bolt 11, the end of expand tube mandrel 15 is provided with conical head, as Fig. 6, Fig. 7 and shown in Figure 8, described expand tube mould comprises four expand tube monomers 9, the conical surface that matches with the conical head of expand tube mandrel 15 is set on the inwall of expand tube monomer 9, expand tube monomer 9 is by the guide holder 91 at rear portion and anterior expand tube head 93 and be connected guide holder 91 and the linking arm 92 of the neck shape of expand tube head 93 constitutes, expand tube head 93 is provided with moulded head 931, offer spring cavity 911 in the guide holder 91, as Fig. 3, Fig. 4 and shown in Figure 5, offer the mandrel hole of matching in the die holder 8 with expand tube mandrel 15, in the wall of die holder 8 along circumferentially evenly being provided with four pilot holes radially 82 that match with guide holder 91, pilot hole 82 outwards has gap 83, guide holder 91 is located in the pilot hole 82, linking arm 92 is arranged in gap 83, be provided with radial spring 13 in the spring cavity 911, the arranged outside of die holder 8 has the cover plate 14 of capping radial spring, its concrete set-up mode is: offer the axial slot cover 81 that matches with cover plate 14 on the outer surface of die holder 8, the bottom of slot cover 81 offers a pair of locking screw pit 811, and being fixed in the slot cover 81 with the rear portion of bolt with cover plate 14---the front portion of cover plate 14 covers radial spring 13, also be provided with the bolt 10 that is used to locate the expand tube mould on the die holder 8, described expand tube mandrel 15 is located in the mandrel hole of die holder 8, and abut in the conical surface of four expand tube monomer 9 inwalls; The inwall of described trip holder 3 is provided with the forming tank that matches with moulded head 931; In the present embodiment, the front in forming tank also is provided with resettlement groove 31 on the inwall of described trip holder 3.During practical application, should there be two above-mentioned forming apparatus for forming pipe end to work together, expand tube mould in two forming apparatus for forming pipe end shifts to install, and makes pipe fitting 18 after passing through these two forming apparatus for forming pipe end moulding respectively, form in pipe fitting 18 ends one complete smooth protruding stupefied.
The process of twice moulding is just the same, just describes its course of work now in detail: at first by clamping cylinder 4 pipe fitting 18 is clamped in the trip holder 3; Then, promoting mainly oil cylinder 2 starts working, the secondary piston bar of promoting mainly oil cylinder 2 drives all parts that are installed on the mount pad 6 and moves forward, because the precompression of radial spring 13, make the expand tube mould be close on the circular cone inclined-plane of conical head of expand tube mandrel 15 front ends, and the cylindrical of the moulded head 931 of expand tube mould and pipe fitting to be processed 18 inwalls have certain clearance, this gap is usually less than 1 millimeter, the expand tube mould just can reach the inboard of pipe fitting 18 to be processed smoothly like this, when arriving the shaping position of regulation, bolt 10 just pushes up trip holder 3 left end face, like this, die holder 8 and all stop motions of expand tube mould, and the secondary piston bar of promoting mainly oil cylinder 2 moves forward, because floating by carrying bolt 11 and axle spring 12 with mounting flange 7, die holder 8 is connected, so, expand tube mandrel 15 moves forward, axle spring 12 is compressed, meanwhile, under the promotion of expand tube mandrel 15 front end conical heads, four separate expand tube monomers 9 of expand tube mould expand outwardly, radial spring 13 is compressed, moulding in the moulded head 931 of four expand tube monomers 9 of expand tube mould squeezes into pipe fitting 18 forming tank that trip holder 3 holds successfully in advance---adjust the stroke of secondary piston bar by regulating stop nut 5 on the back piston bar, when stop nut 5 is resisted against when promoting mainly on the oil cylinder 2, moulding finishes; After the moulding, the secondary piston bar of promoting mainly oil cylinder 2 retreats, axle spring 12 and radial spring 13 resiliences, moulded head 931 up to the expand tube mould spins off from the groove of pipe fitting 18 formings fully, the conical surface of four expand tube monomer 9 inwalls of expand tube mould abuts in the conical head of expand tube mandrel 15 heads, under the drive of secondary piston bar, get back to initial position.In addition, in the mounting groove 31 on the protruding stupefied inwall that is placed on trip holder 3 that last moulding can also be formed, come second of moulding protruding stupefied again.
