Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, the present invention proposes a continuous hemming device, it comprises patrix 1, counterdie 2, core rod 4, base plate 3, described counterdie 2, the space for accommodating pipe fitting 6 is provided with between base plate 3 and core rod 4, described patrix 1 is located at above counterdie 2, with the 2-in-1 mould of counterdie after, the space for accommodating pipe fitting 6 bead portion is provided with between the upper end of patrix 1 and core rod 4, the surrounding edge place of the upper end of described core rod 4 is provided with annular protrusion 5, the described medial surface of protruding 5 is vertically arranged, the lower surface top edge be provided with for blocking pipe fitting 6 of described patrix 1 makes the collar stop 7 of the inside bending of pipe fitting 6, after patrix 1 and the 2-in-1 mould of counterdie, the space of a segmental arc is formed between described block 7 and protruding 5.
Described core rod 4 is through base plate 3, and described base plate 3 againsts the outer surface of core rod 4 and can move up and down relative to core rod 4, when base plate 3 moves upward, promotes pipe fitting 6 and moves upward and carry out bending to pipe fitting 6.
As preferably, described core rod 4 is square, and the upper surface of described core rod 4 is special-shaped end face.Adopt this structure, not only can process the crimping of circular pipe fitting, but also can machining shape be the crimping of square pipe fitting, even and if the end face of institute's crimping not to be that plane also can realize a crimping shaping.
As can be seen from Fig. 1 and Fig. 3 in the present embodiment, the upper surface of core rod on-plane surface, but the often place of protruding 5 is identical relative to the height of core rod upper surface, and the lower surface of patrix is also according to the profile design of the upper surface of core rod, leaves certain space between patrix and core rod.
In the present embodiment, pipe fitting crimping in Fig. 2, due to block and convex role, the neck-in of pipe fitting carries out crimping.In Fig. 4, pipe fitting is entering in the space of block and the protruding segmental arc formed.
After adopting said structure, when flange crimping operation is carried out to pipe fitting, pipe fitting is positioned between upper and lower mould, then control base plate to move upward, promotion pipe fitting moves upward, the upper surface of pipe fitting receives the extruding of patrix, inside crimping continuously under the guiding in the block of patrix and the segmental arc space of male cooperation, due to the existence of projection, block crimping and continue aduncate direction, thus crimping can not be curved inwardly, make crimping one-shot forming, no longer need follow-up shaping operation, simple to operate, ratio of briquetting is high.
For solving the problems of the technologies described above, the present invention proposes a kind of crimping method continuously, and it comprises the following steps:
A, will treat that pipe fitting puts into the counterdie of continuous hemming device, the space between base plate and core rod, wherein said hemming device comprises upper die and lower die, core rod and base plate, described patrix is located at above counterdie, the surrounding edge place of the upper end of described core rod is provided with annular protrusion, the medial surface of described projection is vertically arranged, upper die and lower die matched moulds, makes the space forming a segmental arc between described block and projection;
B, promote base plate and to move upward 3 ~ 10mm, pipe fitting is moved upward, and abuts against with the lower surface of patrix;
C, by automaton promote base plate move upward n time continuously, promotion body moves upward and makes pipe fitting generation bending, collar stop wherein on the lower surface of described patrix is for blocking the top edge of pipe fitting and making the inside bending of pipe fitting, the displacement of each promotion is 3 ~ 10mm, the time interval of each promotion is 1 ~ 3 minute, described n is more than or equal to 3, in the space that the bead portion of pipe fitting is formed between mould and the upper end of core rod;
After d, crimping complete, continue to keep 2-5 minute, and then upper die and lower die are separated, take out product, and put into product to be processed, continue a-c step.
Adopt said method, by the continuous crimping of Lookup protocol, after the end of each motion extruding pipe fitting, all stop cooling a period of time, pipe fitting is shaped, extrude again next time and pipe fitting is bent, adopt in this way, the crimping of pipe fitting can be made to carry out one-step building by the projection of the baffle plate of patrix and counterdie at every turn, and when again extruding after sizing, crimping would not be out of shape easily, thus makes the continuous crimping one-shot forming of pipe fitting, simple and convenient.
Because crimping adopts extruding to make the bend at end of pipe fitting cause, so under extruding, the bending part of pipe fitting can be generated heat deliquescing, if now round-the-clock extruding always, the part that bends can be caused too soft and be out of shape, although owing to being provided with projection, make the part that bends can not inwardly bending, may outwards bending.And adopt this method, when pipe fitting extruding is a bit of, just cools a period of time, the dogleg section of pipe fitting is shaped under block and convex role, and then extrude a bit of, again cool a period of time, the dogleg section of pipe fitting is shaped, go down successively.
