Description
Technical field
This utility model relates to Machining Technology field, more particularly to a kind of swan neck system suitable in large-diameter pipe.
Background technology
In automobile bottom diskware produces, the large-sized heavy-wall tube such as trailing arm, different according to vehicle, the tubing material of its selection, wall thickness, bend pipe angle etc. all have a greater change, and its strength of materials is big, usually can exceed the bend pipe ability of conventional bending machine.For this type of situation, providing business together needs the bending machine of customization all size, and generally trailing arm yield is not high, and this results in substantial amounts of bending machine customization machine and idle situation occurs, and Some Enterprises input and output are disproportionate.Additionally, adopt customization bending machine, owing to pipe bender die can not be adapted to relatively big syphon angle and bigger bend pipe stroke very well, its anti-wrinkling mould easily causes piece surface and pulls and self is easily damaged.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of swan neck system being applicable to large-diameter pipe being avoided that piece surface is pulled.
Technical solution of the present utility model is, a kind of swan neck system being applicable to large-diameter pipe with following structure is provided, including upper mould and counterdie, described upper mould is provided with the briquetting extruding tubing top to be processed, described briquetting is provided with the first placing trough matched with tubing top to be processed, described counterdie includes main boss and the running roller along solid fixed-axis rotation, described the first groove on main boss and the composition of the cannelure on running roller support the second placing trough of part bottom to be processed, described upper die and lower die close up to predeterminated position and form the cavity of the accommodating part to be processed being processed into preset shape.
Preferably, described running roller is two and is uniformly arranged on main boss both sides, and the first described groove center line and cannelure center line are positioned on same.
Preferably, described counterdie also includes the two secondary bosses being separately positioned on main boss both sides, and described secondary boss is provided with second groove suitable with part lower surface to be processed.
Preferably, described counterdie also includes being arranged on main boss both sides by fixed block fixing for part to be processed.
Preferably, described counterdie also includes being arranged in the middle part of main boss supports the telescopic fixing bar of part to be processed.
Preferably, described running roller is one and is arranged at main boss side, and the opposite side of described main boss is provided with the fixed block of fixing part to be processed.
After adopting above structure, a kind of swan neck system suitable in large-diameter pipe of the present utility model, compared with prior art, have the advantage that by arranging running roller, and the first groove on cannelure on running roller and main boss is formed the second placing trough, namely the partial sidewall of the second placing trough is rotating, namely when in the second placing trough owing to there is certain displacement in Forging Process in part, the the second placing trough sidewall being made up of cannelure can move together along with part, greatly reduce the second placing trough directly to rub and displacement in piece surface, the surface making part will not be pulled by the second placing trough, it is particularly suited for the bending of large-diameter pipe, solve due to tubing material on large-diameter pipe, wall thickness, bend pipe angle generation large change brings the problem that piece surface is pulled.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
nullRefer to Fig. 1、Fig. 2、Shown in Fig. 3 and Fig. 4，A kind of swan neck system suitable in large-diameter pipe of offer of the present utility model，Heavy caliber described herein refers to tubing material、Wall thickness、Bend pipe angle has at least the tubing having a greater change，Namely in bend pipe process，Due to tubing material、Wall thickness、Bend pipe angle changes greatly，Piece surface is easily and mould occurs bigger sliding friction to cause piece surface to be pulled and mould self is easily damaged，This device includes mould 1 and counterdie 2，Described upper mould 1 is provided with the briquetting 4 extruding tubing top to be processed，Described briquetting 4 is provided with the first placing trough 5 matched with tubing top to be processed，Described counterdie 2 includes main boss 21 and the running roller 22 along solid fixed-axis rotation，The first groove 31 on described main boss 21 and the composition of the cannelure 32 on running roller 22 support the second placing trough 3 of part bottom to be processed，Described upper mould 1 and counterdie is 2-in-1 holds together to form the cavity of the accommodating part to be processed being processed into preset shape to predeterminated position，By arranging running roller 22，And by cannelure 32 on running roller 22 and on main boss 21 first groove 31 form the second placing trough 3，Namely the partial sidewall of the second placing trough 3 is rotating，Namely when in the second placing trough 3 owing to there is certain displacement in Forging Process in part，The second placing trough 3 sidewall being made up of cannelure 32 can move together along with part，Greatly reduce the second placing trough 3 directly to rub and displacement in piece surface，The surface making part will not be pulled by the second placing trough 3，It is particularly suited for the bending of large-diameter pipe，Solve due to tubing material on large-diameter pipe、Wall thickness、Bend pipe angle generation large change brings the problem that piece surface is pulled.
nullDescribed counterdie 2 also includes being arranged in the middle part of main boss 21 supports the telescopic fixing bar 25 of part to be processed，It is made up of telescopic fixing masthead portion by the first groove 31 partial sidewall on main boss 21，Can be regarded as the first groove 31 partial sidewall and can coordinate along tubing stroke to be processed mobile，Considerably increase operation stability，And main boss 21 is fixed on counterdie，Namely during formation of lots，Main boss 21 can stably support tubing，Or be connected to telescopic for main boss on counterdie，In upper mould extrusion process, main boss moves，Main boss is conflicted at counterdie afterwards，Briquetting coordinates extruding by tubing bending with main fixed block，Described counterdie 2 also includes being arranged on main boss 21 both sides by fixed block 23 fixing for part to be processed，By arranging fixed block 23 and can stably place the large-diameter pipe that processing part especially weight is bigger，Before making bending, tubing position ensures precisely，Improve machining accuracy.
Described running roller 22 is two and is uniformly arranged on main boss 21 both sides, the first described groove 31 center line and cannelure 32 center line are positioned on same, running roller 22 is set to two and is respectively provided with boss both sides again, can by tubing with a shape bending 3 sections, not only working (machining) efficiency is high, and bending, it is to avoid the site error on repeatedly fixing, improve machining accuracy.
Described counterdie 2 also includes the two secondary bosses 24 being separately positioned on main boss 21 both sides, described secondary boss 24 is provided with second groove 33 suitable with part lower surface to be processed, further strengthen the second placing trough 3, make the second placing trough 3 structure stable equilibrium more, and running roller 22 upward pressure can be shared, it is ensured that total is reliable and stable.
Described running roller 22 is one and is arranged at main boss 21 side, the opposite side of described main boss 21 is provided with the fixed block 23 of fixing part to be processed, suitable in asymmetric only dogleg section etc. situation, by coordinating in fixed block 23, can stably fix tubing bending, volume is little, and working (machining) efficiency is high.
