Description

A kind of expanding die for ring ripple cone cylinder
Technical field
The invention belongs to mould bulging processing technique field, particularly relate to a kind of expanding die for ring ripple cone cylinder.
Background technology
The ring ripple cone cylinder of certain aero-engine is annular revolution bulk wave rib part, and as shown in Figure 3, at present, generally adopt roller roll forming processing, roll extrusion precision is low, cannot ensure dimensional tolerance for its structure; Processing method common in addition adopts the processing of mould bulging, and expanding die is divided into internal-expansion type, outer receipts internal-expansion type two kinds of expanding dies by structure.
Internal-expansion type expanding die is the most basic structure, mould is made up of parts such as cope match-plate pattern, lower bolster, swollen lobe, core rods, add man-hour, product to be processed is enclosed within outside swollen lobe, when equipment presses down, cope match-plate pattern band moving-mould-core moves downward, coordinated by the gradient of core rod with swollen lobe, and coordinated with the slideway that backing plate is processed by the slide plate be contained on swollen lobe, promote swollen lobe radially to move, product to be processed is processed into the shape of needs, but this interior swollen type expanding die structure is simple, can only process the revolving parts that bus is straight line.
Outer receipts internal-expansion type expanding die is compared with the complex structure of internal-expansion type bulging die, the basis of interior swollen type expanding die adds outer shroud block and outer swollen lobe, during forming parts, outer swollen lobe forms the external mold meeting product end-state under the effect of outer shroud block, swollen lobe continues outwards swollen, final with outer swollen split-ring mold, make forming parts be bus to be the revolving parts of complex profile; The shortcoming of this outer receipts internal-expansion type expanding die is that product upper and lower end different diameters can not be excessive, and shape of generatrix can not be too dark, and product height can not be too high, otherwise cannot pick and place part, and easily cause upper and lower side diameter uneven, poor dimensional precision.
According to the structure characteristic analysis of ring ripple cone cylinder, the expanding die of above-mentioned two kinds of structures all can not meet the bulging processing of ring ripple cone cylinder.
Summary of the invention
For prior art Problems existing, the invention provides a kind of expanding die for ring ripple cone cylinder, this mould solves the problem being difficult to pick and place that ring ripple cone cylinder causes because two ends different diameters is comparatively large in expansion shape forming process, and due to the highly higher ring ripple cone cylinder technical problem that upper and lower port dimensional accuracy is inconsistent in forming process caused, realize the processing of ring ripple cone cylinder unitary mould bulging.

Below in conjunction with accompanying drawing, a use procedure of the present invention is described:
As shown in Figure 1, adopt expanding die of the present invention to make the process of ring ripple cone cylinder, concrete steps are as follows:
Step one: prepare blank: blank is bore the identical taper cone barrel of cylinder tapering with ring ripple, its external diameter, than the external diameter trough extremely when young 5mm of ring ripple cone cylinder, is welded together by the two ends of sheet material and makes;
Step 2: mould is installed: expanding die of the present invention is installed on a hydraulic press, lower bolster 1 of the present invention to be compressed with the lower platform of hydraulic press by pressing plate and is connected, cope match-plate pattern 2 to be compressed with the upper mounting plate of hydraulic press by pressing plate and is connected, hydraulic press jogger hole is put in the bottom of push rod 19, and the top of push rod 19 withstands on the bottom of supporting plate 8 through the jogger hole 23 of lower bolster 1;
Step 3: charging: the upper mounting plate rising hydraulic press, cope match-plate pattern 2 is driven to rise, thus band moving-mould-core 6 and fixed head 11 rise, because the second screw 15 and fixed head 11 are floating connection, in being fixedly connected with the second screw 15, swollen lobe 3 is not moved, because core rod 6 rises, then, swollen lobe 3 moves down relatively along the guide runner of core rod 6, interior swollen lobe 3 inwardly shrinks while relatively moving down, when the head of the second screw 15 contacts with the end face of fixed head 11, second screw 15 drives interior swollen lobe 3 to rise, during the height of the distance between the bottom surface and the end face of outer swollen lobe 5 of interior swollen lobe 3 higher than blank, liftout tank under primer fluid press, make push rod 19 promote supporting plate 8 to move upward, thus swollen lobe 5 moves upward along outer slide plate 10 outside promoting, the outwards expansion of outer swollen lobe 5, mould is opened, the madial wall of swollen lobe 5 outside loads blank,
Step 4: expansion shape forming: after blank installs, under hydraulic press, liftout tank falls, supporting plate 8 is fallen back to contact with the end face of lower bolster 1, the upper mounting plate of hydraulic press presses down, core rod 6 and interior swollen lobe 3 are fallen simultaneously, until interior swollen lobe 3 is fallen on supporting plate, stop falling, the upper mounting plate of hydraulic press continues to press down, core rod 6 continues to fall, core rod 6 and interior swollen lobe 3 Relative sliding, interior swollen lobe 3 circumferentially radially outward expansion, fixed head 11 compresses first simultaneously, second spring, in making, outer swollen lobe is pressed on supporting plate 8, in preventing, outer swollen lobe dislocation, along with the upper mounting plate of hydraulic press presses down, interior swollen lobe 3 is under the radial component effect of core rod 6, outer swollen lobe 5 is matched moulds under the radial component effect of outer shroud 4, in making to be clipped in, blank expansion shape forming between outer swollen lobe is ring ripple cone cylinder,
Step 5: die sinking feeding: after the shaping end of ring ripple cone cylinder, repeat step 3 and (rise the upper mounting plate of hydraulic press, cope match-plate pattern 2 is driven to rise, thus band moving-mould-core 6 and fixed head 11 rise, because the second screw 15 and fixed head 11 are floating connection, in being fixedly connected with the second screw 15, swollen lobe 3 is not moved, because core rod 6 rises, then, swollen lobe 3 moves down relatively along the guide runner of core rod 6, interior swollen lobe 3 inwardly shrinks while relatively moving down, when the head of the second screw 15 contacts with the end face of fixed head 11, second screw 15 drives interior swollen lobe 3 to rise, during the height of the distance between the bottom surface and the end face of outer swollen lobe 5 of interior swollen lobe 3 higher than blank, liftout tank under primer fluid press, make push rod 19 promote supporting plate 8 to move upward, thus swollen lobe 5 moves upward along outer slide plate 10 outside promoting, the outwards expansion of outer swollen lobe 5) open to mould, shaping ring ripple cone cylinder and interior, outer swollen lobe is separated, and ring ripple cone cylinder and interior, sufficient space is had between outer swollen lobe, take off ring ripple cone cylinder.
