Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
It please refers to as shown in Figure 1 to Figure 3, it is in a specific embodiment, provided by the invention to carry scalable material returning sleeve
Undershoot header structure include drift mounting seat 1, low punch 2, elastic component 3 and punch material returning sleeve 4.Wherein：
The stair-stepping installation slotted eye inwardly concaved, the mounting groove are formed on the upper surface of the drift mounting seat 1
Hole includes the first installation slotted eye 11 and the second installation slotted eye 12 for being connected to first installation slotted eye, 11 top, first peace
Tankage hole 11 is coaxially disposed with second installation slotted eye 12, and the aperture of first installation slotted eye 11 is less than described second and installs
The aperture of slot 12.
The low punch 2 includes the punch ontology 21 of cylinder and is formed in the cylinder of 21 lower end of punch ontology
Punch mounting portion 22, the diameter of the punch mounting portion 22 are more than the diameter of the punch ontology 21, the punch mounting portion 22
It is contained in first installation slotted eye 11, the upper end of the upper surface of the punch mounting portion 22 and first installation slotted eye 11
Opening flushes, and the punch ontology 21 extends upward second installation slotted eye 12.In the present embodiment, the punch installation
The diameter in portion 22 and the aperture of first installation slotted eye 11 are roughly equal, therefore the punch mounting portion 22 is able to elastic conjunction
In in first installation slotted eye 11, to improve the stability of the low punch 2.
The elastic component 3 is set in the lower end of the punch ontology 21 and in second installation slotted eye 12.It is described
The lower face of elastic component 3 is supported on the upper surface of the punch mounting portion 22.When the elastic component 3 is in diastole state,
End face is higher than the upper surface of second installation slotted eye 12 thereon.The punch material returning sleeve 4 is then slidably located in the punch sheet
Outside body 21, the lower face of the punch material returning sleeve 4 is supported on the upper surface of the elastic component 3.So that when the elasticity
When part 3 is in diastole state, retain between the lower face of the punch material returning sleeve 4 and the upper surface of second installation slotted eye 12
There is gap.
In the present embodiment, the lower end of the punch material returning sleeve 4 is formed with the limiting section 41 outwardly protruded, the limiting section 41
Outer diameter be more than second installation slotted eye 12 aperture.Preferably, the outer diameter of the limiting section 41 and the drift mounting seat 1
Outer diameter it is equal so that the outer wall of the limiting section 41 is flushed with the outer wall of the drift mounting seat 1.
When the elastic component 3, which is pressurized, to be compressed, the punch material returning sleeve 4 is along the punch ontology 21 downwards (towards institute
State drift mounting seat 1) sliding, until the lower face and the upper surface of the drift mounting seat 1 of the limiting section 41 are inconsistent.
When 3 decompression diastole of the elastic component, the punch material returning sleeve 4 (deviates from institute upwards along the punch ontology 21
State drift mounting seat 1) sliding, so that between the lower face of the limiting section 41 and the upper surface of the drift mounting seat 1
Gap is formed again.
In the present embodiment, the diameter of the aperture of the endoporus of the elastic component 3 and the punch ontology 21 it is roughly equal or
It is slightly less than the diameter of the punch ontology 21, therefore the elastic component 3 can fit snugly in the bottom of the punch ontology 21.
The outer diameter of the elastic component 3 is then more than the aperture of first installation slotted eye 11, therefore a part for the elastic component 3 can prop up
It supports on the step surface between second installation slotted eye 12 and first installation slotted eye.
In the present embodiment, the elastic component 3 can be a rubber ring with predetermined thickness.Certainly, in some other reality
It applies in example, the elastic component 3 can also use spring.
It please refers to Fig.4 to shown in Fig. 6, the operation principle of the undershoot header structure with scalable material returning sleeve in the present embodiment
It is as follows：
Step 1: moved up as shown in figure 4, controlling the undershoot header structure, until the top of the low punch 2 with wait for
The lower face of the workpiece 100 of extrusion forming contradicts；
Step 2: as shown in figure 5, continue control undershoot header structure it is upward, the workpiece 100 is extruded together.This
When：The top of the low punch 2 enter in workpiece 100 and with 100 tight structure of workpiece, meanwhile, the elastic component 3 is fully pressed
Contracting, the lower face of the limiting section 41 and the upper surface of the drift mounting seat 1 are inconsistent；
Step 3: as shown in fig. 6, control undershoot header structure moves down backhaul, the elastic component 3 presses diastole to push
The punch material returning sleeve 4 pushes up workpiece 100 along 21 upward sliding of punch ontology, the punch material returning sleeve 4, to
So that workpiece 100 automatically disengages the punch ontology 21.
As it can be seen that the undershoot header structure provided by the invention with scalable material returning sleeve, by being set on low punch ontology
Punch material returning sleeve and elastic component are set, to realize being automatically separated for workpiece and low punch, to ensure that material returned effect, is promoted
Production efficiency.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in fields
Personnel are it should be understood that the description in embodiment is only exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change should all belong to the scope of protection of the present invention.Scope of the present invention is by the power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
