Description

Shaping and the swollen bag integration mold of a kind of port
Technical field
The utility model relates to tubing deep process technology field, specifically refers to a kind of mould, particularly relates to the shaping and swollen bag integration mold of a kind of port.
Background technology
Internal high pressure forming is also hydroforming or Hydraulic shaping, is that one utilizes liquid as shaping medium, by controlling interior pressure and material flowing reaches the material forming technique of shaped hollow part object.
The principle of internal high pressure forming by internal pressurization and axial afterburning feed supplement, pipe is pressed into mold cavity to make it be configured as required workpiece.Be the part of curve for axis, need pipe to be pre-bent to close to part shape, then press molding.
When utilizing internal high pressure forming manufacture technics pipe fitting, because pipe fitting is substantially all with arc or curve shape, and because of the difference of part machinery performance requirement, pipe fitting material everywhere, thickness are all variant, so the bending force that pipe fitting knee needs is also different.Existing in pipe part inside shaping basic employing inner high voltage mould molding from inside to outside, but there is following problem:
1, inner high voltage mould development cost is very high: general common internal high pressure forming die price price can at more than 10W not etc., and will coordinate special inner high voltage forming press to use;
2, the scope of application of inner high voltage mould is narrower: less for forming shape, and such as, diameter in the utility model is 11mm, and thickness is the pipe part of 2mm, even if adopting internal high pressure forming die shaping is also that difficulty is very large.
Therefore be necessary to provide a kind of mould, for processing this type of tubular member.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide the shaping and swollen bag integration mold of a kind of port, adopt three forms driving the composite die of oil cylinder combination, so mould does not belong to the shaping category of inner high voltage, then the cost of mould development is reduced, actual development cost is only 40% of general category internal high pressure forming die, and this type of mould does not need to coordinate special inner high voltage forming press, only coordinates universal hydraulic forming machine.
The utility model is achieved through the following technical solutions:
Shaping and the swollen bag integration mold of a kind of port, comprise model fixing seat, lower model fixing seat, the lower end of described upper model fixing seat is provided with patrix, the lower end of described lower model fixing seat is provided with counterdie, form a die cavity between described upper die and lower die, this mould also comprises main driving oil cylinder, secondary driving oil cylinder A, secondary driving oil cylinder B, pusher; Described main driving oil cylinder is arranged on the upper side of lower model fixing seat, and the secondary oil cylinder A that drives is connected by the piston rod of contiguous block with main driving oil cylinder with the secondary oil cylinder B that drives; In described die cavity, forming core shaft is installed, is provided with in described forming core shaft and drives mandrel and forming convax mould; One end and the described pair of described pusher drive the piston rod of oil cylinder A, pair drives the piston rod of oil cylinder B to be connected, and the other end of pusher is connected with driving mandrel.
As optimal technical scheme of the present utility model, described driving mandrel is socketed with back-moving spring A.
As optimal technical scheme of the present utility model, described forming convax mould is socketed with back-moving spring B.
Compared with prior art, the beneficial effects of the utility model are:
1, the development cost of mould is reduced: this die cost is only 40% of the similar die cost of inner high voltage;
2, improve more mold exchange and debugging mould efficiency: mould is once adjusted, and does not need adjustment afterwards in production process, and the extraneous factor such as oil pressure, temperature can not be subject in process of production affect product quality;
3, equipment purchase expense is reduced: this type of mould only coordinates Normal hydraulic forming machine to use, and does not need to adopt high-end inner high voltage forming press.

Fig. 2 is top view of the present utility model;
Fig. 3 is partial sectional view of the present utility model;
Fig. 4 is the A portion enlarged drawing in Fig. 3.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Fig. 1 is front view of the present utility model, and Fig. 2 is top view of the present utility model, and Fig. 3 is partial sectional view of the present utility model, and Fig. 4 is the A portion enlarged drawing in Fig. 3.
Shaping and the swollen bag integration mold of described a kind of port, comprise model fixing seat 1, lower model fixing seat 2, the lower end of described upper model fixing seat 1 is provided with patrix 3, the lower end of described lower model fixing seat 2 is provided with counterdie 4, form a die cavity 5 between described patrix 3 and counterdie 4, also comprise main driving oil cylinder 6, secondary driving oil cylinder A7, secondary driving oil cylinder B8, pusher 9; Described main driving oil cylinder 6 is arranged on the upper side of lower model fixing seat 2, and the secondary oil cylinder A7 that drives is connected by the piston rod of contiguous block 10 with main driving oil cylinder 6 with the secondary oil cylinder B8 that drives; In described die cavity 5, forming core shaft 11 is installed, is provided with in described forming core shaft 11 and drives mandrel 12 and forming convax mould 13; One end and the described pair of described pusher 9 drive the piston rod of oil cylinder A7, pair drives the piston rod of oil cylinder B8 to be connected, the other end of pusher 9 is connected with driving mandrel 12, described driving mandrel 12 is socketed with back-moving spring A14, described forming convax mould 13 is socketed with back-moving spring B15.
Its operation principle is:
In use, first put in die cavity 5 and need shaping pipe part, closed patrix 3 and counterdie 4; Then main driving oil cylinder 6 is promoted, then the forming core shaft 11 be connected with main driving oil cylinder 6 travels forward and enters die cavity 5, forming core shaft 11 acts on the pipe part in die cavity 5, such pipe part is swollen, and mouth is shaping complete, because of pair drive oil cylinder A7, the secondary oil cylinder B8 that drives is connected with the piston rod of main driving oil cylinder 6 by contiguous block 10, so driven forward together.
When the piston rod of main driving oil cylinder 6 advances to fixed position, after swollen mouth is shaping; Secondary driving while of the piston rod of oil cylinder A7, secondary driving oil cylinder B8 ejects forward, act on pusher 9, pusher 9 again driven forward drives mandrel 12, and because forming convax mould 13 is 30 ° of wedge relations with driving mandrel 12 junction, so when driving mandrel 12 to travel forward, forming convax mould 13 moves downward, and then ejects dot shape from inside to outside in pipe part inside.
Description as can be seen from above-mentioned operation principle: this mold forming structure needs to install in forming core shaft 11 to drive mandrel 12 and forming convax mould 13, be subject to the impact of pipe part diameter and parts intensity, so this mould only can process the inner local of pipe part, outwards minor structure is shaping, be under the jurisdiction of the shaping proprietary solutions of the inner outwards local minor structure of pipe part, overcome the shortcoming of internal high pressure forming die for outside local, this type of inside minor structure difficult forming.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
