The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further describe the utility model.
A kind of forging-ring processing unit (plant) as Figure 1-5, comprise the patrix being arranged on forging press, described patrix comprises backward extrusion bar 1, on described backward extrusion bar 1, be provided with extruding termination 3, by connecting, pin-and-hole 31 is dismountable to be connected on backward extrusion bar 1 in described extruding termination 3, described forging-ring processing unit (plant) also comprises the travelling table that the first counterdie and the second counterdie are installed, described the first counterdie is provided with backward extrusion cylinder 2, described the second counterdie is provided with die sleeve, cut hole gasket ring 5 is installed in described die sleeve, described extruding termination 3 comprises location division and punch, on described location division, locating hole is set, described punch is by clamping plane 35, circular arc shunting is with 34, calibrating strap 33, withdraw of the needle guidance tape 32 forms, it is R10-R20mm that 34 radiuses are with in described circular arc shunting, described calibrating strap 33 is 15-25mm.
The utility model for aluminum alloy forging ring backward extrusion, produce in eccentric large, the forging-ring of the ubiquitous forging-ring problem that is not easy the demoulding after crooked improve.The bias of forging-ring (Wall-Thickness Difference) size is mainly determined by aspects such as equipment precision, processing mold, operative skills, conventionally adopt the extruding termination 3 with tapering, but in actual extrusion process, because distortion is not very evenly easily to cause forging-ring bias increasing, wayward; In addition, if forging-ring bends, backward extrusion bar 1 and extruding termination 3 cannot be separated with forging-ring, cause forging-ring (forging-ring) to take out, and cause to produce and interrupt, and after destruction forging-ring, forging-ring could be taken out;
As shown in Figure 1, extruding termination 3 is in the past by clamping plane 35, tapering band 36, circular arc shunting is with 34, calibrating strap 33, withdraw of the needle guidance tape 32 grades partly form, than before extruding termination 3, tapering band 36 has been cancelled in the extruding termination 3 of this forging-ring processing unit (plant), be with 34 to be optimized design and (according to pushing termination diameter, to change former R5mm into R10-R20mm circular arc shunting, double do metal distinguished and admirable and centering effect), it (is 15-25mm by 10mm lengthening that calibrating strap 33 suitably lengthens, play the effect that determines forging-ring diameter of bore, lengthen the length of calibrating strap 33, can increase metal flow resistance, thereby make frictional force distribute more even in circumferential location, thereby reach the effect of rectifying eccentricity), increase by one simultaneously and compress plain cushion 4, this compresses plain cushion 4 by manipulator control, forging-ring blank in heating enters after backward extrusion cylinder 2, compression plain cushion 4 is placed on forging-ring, last backward extrusion bar 1 is exerted pressure downwards and is compressed blank (first blank being pressed to full pressing in 2 li, backward extrusion cylinder), prevent that in extrusion process, blank moves, after compression completes, to compress plain cushion 4 takes out, now then will push termination 3 centerings, carry out backward extrusion, the backward extrusion forging-ring degree of eccentricity out can reach in 5mm conventionally like this, owing to having increased by one, compress operation, substantially very close to each other between blank and backward extrusion cylinder 2, in addition owing to being that the punch bottom of extruding termination 3 is plane, large with the contact area of blank, as long as, by backward extrusion bar 1 and backward extrusion cylinder team 2, in extrusion process, forging-ring the changing of the relative positions can not occur substantially before extruding, so the forging-ring end face of extruding is concordant, wall thickness is even.
In addition the conversion between different size forging-ring can be realized in the extruding termination 3 of, changing different-diameter.
In actual production, according to the plastic deformation feature of the outside dimension of forging-ring, wall thickness, different-alloy, select suitable circular arc to shunt R value, the calibrating strap 33 length H values with 34, it is smooth that the forging-ring that makes to extrude has inner and outer round surface, end face is smooth, Wall-Thickness Difference within the limits prescribed, the feature such as inner hole extruding little residue.
The utility model has greatly reduced the probability that is not easy the demoulding after forging-ring bending, but can not stop completely to occur, in order to solve this situation, described forging-ring processing unit (plant) also comprises the travelling table that the first counterdie and the second counterdie are installed, described the first counterdie is provided with backward extrusion cylinder 2, described the second counterdie is provided with die sleeve, cut hole gasket ring 5 is installed in described die sleeve, if forging-ring bends aborning, while causing forging-ring to take out, can take following measures, 1. forging-ring and backward extrusion bar 1 are together taken out from backward extrusion cylinder 2, travelling table moves to another station that the second counterdie is housed, 2. select the annulus that an internal-and external diameter mates substantially with forging-ring internal-and external diameter as cut hole gasket ring 5, to put in the die sleeve of the second counterdie, forging-ring and cut hole gasket ring 5 align substantially, the patrix being arranged on forging press moves down, utilize the gap between forging-ring endoporus and cut hole gasket ring 5, directly forging-ring endoporus is cut and worn, forging-ring becomes a bottomless straight tube, 3. take out the connecting pin between extruding termination 3 and backward extrusion bar 1, extruding termination 3 Automatic-fallings, because the gap between forging-ring endoporus and backward extrusion bar 1 is larger, so can realize separation between forging-ring energy and backward extrusion bar 1 like a cork.
By above die improvement, and the process modification adapting with it, the backward extrusion forging-ring degree of eccentricity out can reach in 5mm conventionally like this, and the demoulding difficulty that forging-ring bending causes is resolved, so production efficiency is also improved.
The technical scheme above the utility model embodiment being provided is described in detail, applied specific case herein the principle of the utility model embodiment and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
