Provided with that can penetrate the second stretching die in the upper mould of stretching in hole, second stretching die is in the form of a column structure and is connected with frame.
Principle of the present utility model is as follows：
This filter casing realizes plate same with stretching-machine by the mold component and lower die assembly of mutual cooperation
Stretching twice in one machine.
Under initial state, the first pulling motion mechanism and the second pulling motion mechanism action make mould under blanking, binder gear
Block, the first stretching die top surface (i.e. towards the surface of mold component side) it is concordant.Plate is admitted to after stretching-machine, will be fallen
Under blanking upper die and blanking between mould.In the presence of mold actuating unit, blanking upper die down move by die assembly side,
And take the lead in touching plate, realize blanking.Plate after blanking falls into the material-dropping hole under blanking in mould immediately.Then, first
Pulling motion mechanism action, with closed die power press, makes blanking upper die be pressed together on binder block, plate is clamped at
On material between mould and binder block.As blanking upper die is continued to move to, plate can be by the first stretching closing mould stretching.Now, first draw
Stretching mould will be as stretching convex die, and blanking upper die is then as stretching cavity plate, longitudinal progress first time of the plate along the first stretching die
Stretch and enter the inside of mould under blanking.Then, the stopping of the first pulling motion mechanism is acted, the second pulling motion mechanism action,
Plate is set to be clamped between compression edge and binder block.As mold actuating unit drives mold component to continue traveling downwardly,
Second stretching die will be as stretching convex die, and mould is then as stretching cavity plate in stretching, and longitudinal direction of the plate along the second stretching die carries out the
Succeeding stretch and the inside for entering the upper mould of stretching.
Because the first pulling motion mechanism from the second pulling motion mechanism can produce two kinds of different and separate works
Firmly, therefore, in time processing flow, mold component and lower die assembly can have the different stretching of two groups of demands with recessed
Mould and punch-pin, so as to realize that a stretching-machine completes the twice stretching process of filter casing.

The course of work of the filter casing stretching-machine of the present embodiment is as follows：
Under original state, mold component and lower die assembly are in open mode.Periphery oil cylinder 17 and center oil cylinder 18
Action, makes the top surface of mould 12 under blanking, the stretching die 14 of binder block 13 and first (i.e. towards the surface of mold component side)
Concordantly.Mold component is located at up stop position, and now, guide pillar body 25 is still located in guide column sleeve 24.
Plate is sent into after stretching-machine along stock guide, and master cylinder 6 is acted, and drives the fast downlink of movable transverse beam slab 5, and then drive
Blanking upper die 10 is moved toward the side of mould under blanking 12, until speed transformation induction switch 28 senses speed transformation induction collision block
32, master cylinder 6 adjusts downstream rate, drives movable transverse beam slab 5 descending at a slow speed.Because blanking upper die 10 is near lower mould
Has the side of component, blanking upper die 10 can take the lead in touching mould 12 under plate, blanking upper die 10 and blanking and carry out blanking immediately.
After blanking terminates, the plate after blanking falls into the material-dropping hole under blanking in mould 12 immediately.Then, periphery oil cylinder
17 produce pressure, and center oil cylinder 18 remains motionless, blanking upper die 10 is pressed together on binder block 13, and plate is clamped at
On material between mould 10 and binder block 13.As the continuation of master cylinder 6 drives, blanking upper die 10 is descending, and plate can be by the first stretching die
14 stretchings.Now, the first stretching die 14 will be as stretching convex die, and blanking upper die 10 is then as stretching cavity plate, and plate is along first
The longitudinal direction of stretching die 14 carries out first time stretching and enters the inside of mould 12 under blanking.
Pressure-pad-force transformation induction collision block is sensed when movable transverse beam slab 5 persistently comes downwards to pressure-pad-force transformation induction switch 29
33, stretching for the first time terminates immediately, the pressure valve off-load of periphery oil cylinder 17, and center oil cylinder 18 then produces pressure, makes plate quilt
It is clamped between compression edge 15 and binder block 13.As the continuation of master cylinder 6 drives, blanking upper die 10 is descending, and plate can be by second
Stretching die 16 is stretched.Second stretching die 16 will be as stretching convex die, and mould 8 is then as stretching cavity plate in stretching, and plate is drawn along second
The longitudinal direction for stretching mould 16 carries out second of stretching and enters the inside of the upper mould 8 of stretching.
When master cylinder 6 is continued traveling downwardly, until the first downward storke inductive switch 27 senses that the sensing of the first downward storke is touched
Block 31, the stopping immediately of master cylinder 6 action and pressure release.The venting duration of master cylinder 6 reaches after setting value that master cylinder 6 will drive and live
Dynamic header board 5 is up, and then drives mold component up, until the first up stroke inductive switch 26 senses that first is up
Stroke senses collision block 30.Now, the stopping of master cylinder 6 is acted, and movable transverse beam slab 5 is reset to original state.Meanwhile, periphery oil cylinder 17
It will be acted with center oil cylinder 18, and drive binder block 13 up with the first stretching die 14 respectively, until the sensing of the second up stroke
Switch 34 senses that the second up stroke sensing collision block 36, the 3rd up stroke inductive switch 38 sense the 3rd up stroke sense
Collision block 41 is answered, periphery oil cylinder 17 is that stopping is acted and off-load with center oil cylinder 18, and mould 12, binder block 13 and first are drawn under blanking
The top surface for stretching mould 14 recovers concordant, completes a working cycles.
In a working cycle process, the second downward storke inductive switch 35 and the second downward storke sensing collision block 37,
3rd downward storke inductive switch 39 and the 3rd downward storke sensing collision block 42 can shield, it is to avoid periphery oil cylinder 17 or
The downward storke of center oil cylinder 18 is excessive and damages lower die assembly.
