A kind of circular pipe shaping and piercing die mould equipment all-in-one
The utility model relates to punch forming mechanism, particularly a kind of circular pipe shaping and piercing die mould equipment all-in-one.
A kind of distributing pipe (the pipe part that diameter 20mm, wall thickness are 2.5mm) is for high pressure project PSA fuel pipe.Because the material thickness of this distributing pipe is 2.5mm, the difficult point of its making is the face of clapping, according to product size requirement, if adopting common punch press to add mould manufactures, very difficult guarantee clap uniformity and the stability of face, this is because can produce the phenomenon of resilience after material plasticity distortion, if want the degree of decreasing rebound, just need to there is the process of a pressurize, and common punch press is the reciprocating motion that camshaft band movable slider forms kinetic energy, mold work parts contact can only complete in moment completely with workpiece, there is no the process of pressurize.
The plastic forming of product need contact completely with workpiece (plug) in addition, due to the factor of frictional force, adopts the mode of manually loosing core, and not only production capacity is low, and sustainability production is lower, cannot ensure product quality simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of circular pipe shaping and piercing die mould equipment all-in-one, it mainly solves the existing technical problem of above-mentioned prior art, it is an automation, have the equipment of pressure holding function, in order to improve the efficiency of production and the uniformity of product and stability, mould is united two into one into special equipment with equipment simultaneously.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of circular pipe shaping and piercing die mould equipment all-in-one, it is characterized in that: it comprises the mould being arranged in frame, this mould top is provided with the press that pneumohydraulic pressure-cylinder drives, this mould one side is provided with core-pulling mechanism, this mould also comprises two groups of punching dies and mould, this punching die all has by the side blow mechanism with spring of hydraulic oil cylinder driving separately, this mould is connected and is controlled by booster, and this booster, pneumohydraulic pressure-cylinder, core-pulling mechanism, press and oil cylinder are connected control by electric cabinet.
Described circular pipe shaping and piercing die mould equipment all-in-one, is characterized in that: in this frame, have protective cover, this protective cover is accommodated in the inner mould, press, punching die and mould.
The utility model is compared with existing conventional art, and tool has the following advantages:
1, punching: production method routinely, need three process to complete the process (rush four holes, rush single hole, rush single hole) of punching, and the utility model can rush in 6 holes simultaneously, utilize the programme-control time difference, four holes of punching in advance, under the state that completes and close at mould, utilize oil cylinder to drive punching die, punching from bottom to top simultaneously goes out two angle holes, adopts programme-control automatically to take out (sending) plug mode, automatically move back waste material mode and combine, complete the automatic continuous production of punching technology.
2, pressing face: pressing face is the most difficult operation completing in whole production, because product plastic deformation produces rebound phenomenon, the utility model utilize pneumohydraulic pressure-cylinder slowly, the function of capable of continuous pressurization and pressurize, offset rebound phenomenon in common stamping procedure, ensure stability and the uniformity of product quality.
3, merge: because punching technology solves with flattening technology difficult point, the utility model is on secondary twice process integration to equipment, and each action goes out a qualified product.
Therefore, the utility model has solved the key issue of production capacity and quality, increases substantially the stability of production capacity and product quality, larger reduction workman's labour intensity, reduce artificial and equipment cost.

Detailed description of the invention
Refer to Fig. 1-4, the utility model discloses a kind of circular pipe shaping and piercing die mould equipment all-in-one.As shown in the figure: it comprises the mould 1 being arranged in frame 7, this mould 1 top is provided with the press 2 that pneumohydraulic pressure-cylinder 3 drives, and these mould 1 one sides are provided with core-pulling mechanism 6, and this mould 1 also comprises two groups of punching dies 9,16 and mould 16.This punching die 9,16 all has the side blow mechanism with spring 14,15 12,13 by oil cylinder 10,11 drives separately, this mould 16 connects control by booster 8, and this booster 8, pneumohydraulic pressure-cylinder 3, core-pulling mechanism 6, press 2, oil cylinder 10, oil cylinder 11 connect control by electric cabinet 5.
When the utility model uses, distributing pipe is put into punching die 9, in 16, touch hand switch, plug is under core-pulling mechanism 6 is loosed core the effect of cylinder force, drive plug to enter distributing pipe, plug is delivered to behind position, press 2 on mould 1 moves downward under the effect of pneumohydraulic pressure-cylinder 3, mould 1 rushes the action of four holes and moulding, then the process of carrying out supercharging of pneumohydraulic pressure-cylinder 3, after being pressurized to 120T, carry out pressurize, discharge moulding stress, at pressurize oil cylinder 10 simultaneously, 11 driving side punch mechanisms 12, 13 rush the action of side opening, oil cylinder 10 after stamping-out, 11 off-loads, at spring 14, under the effect of 15 power, by side blow mechanism 12, 13 drift resets, punching die 9 after pressurize 5s, 16 separately, by punching die 9, the fabricated part of making in 16 takes out, then the part of hole punch is put into mould 16, so carry out the action of repetition.
As a kind of preferred structure, in this frame 7, there is protective cover 4, this protective cover 4 is accommodated in the inner mould 1, press 2, punching die 9, punching die 16 and mould 16, contributes to the protection to device core mechanism, increases the service life.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should be technology category of the present utility model.
