Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
It please refers to as shown in Figure 1 to Figure 3, it is in a specific embodiment, provided by the utility model to be moved back with scalable
The undershoot header structure of material set includes drift mounting seat 1, low punch 2, elastic component 3 and formed 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 11 top of the first installation slotted eye, first peace
Tankage hole 11 and second installation slotted eye 12 are coaxially disposed, and the aperture of first installation slotted eye 11 is less than second installation
The aperture of slot 12.
The low punch 2 includes cylindrical formed punch ontology 21 and is formed in the cylindrical of 21 lower end of formed punch ontology
Formed punch mounting portion 22, the diameter of the formed punch mounting portion 22 are greater than the diameter of the formed punch ontology 21, the formed punch mounting portion 22
It is contained in first installation slotted eye 11, the upper end of the upper surface of the formed punch mounting portion 22 and first installation slotted eye 11
Opening flushes, and the formed punch ontology 21 extends upward second installation slotted eye 12.In the present embodiment, the formed punch installation
The diameter in portion 22 and the aperture of first installation slotted eye 11 are roughly equal, therefore the formed 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 formed punch ontology 21 and is located in second installation slotted eye 12.It is described
The lower end surface of elastic component 3 is supported on the upper surface of the formed 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 formed punch material returning sleeve 4 is then slidably located in the formed punch sheet
Outside body 21, the lower end surface of the formed 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 end surface of the formed 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 formed punch material returning sleeve 4 is formed with the limiting section 41 outwardly protruded, the limiting section 41
Outer diameter be greater 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 formed punch material returning sleeve 4 is downward (towards institute along the formed punch ontology 21
State drift mounting seat 1) sliding, until the lower end surface of the limiting section 41 and the upper surface of the drift mounting seat 1 are inconsistent.
When the 3 decompression diastole of elastic component, the formed punch material returning sleeve 4 (deviates from institute upwards along the formed punch ontology 21
State drift mounting seat 1) sliding, so that between the lower end surface 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 inner hole of the elastic component 3 and the formed punch ontology 21 it is roughly equal or
It is slightly less than the diameter of the formed punch ontology 21, therefore the elastic component 3 can fit snugly in the bottom of the formed punch ontology 21.
The outer diameter of the elastic component 3 is then greater than the aperture of first installation slotted eye 11, therefore a part of 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 shown in fig. 4 to fig. 6, the working 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 to
The lower end surface 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 sufficiently pressed
Contracting, the lower end surface of the limiting section 41 and the upper surface of the drift mounting seat 1 are inconsistent；
Step 3: the elastic component 3 presses diastole to push as shown in fig. 6, control undershoot header structure moves down backhaul
The formed punch material returning sleeve 4 pushes up workpiece 100 along 21 upward sliding of formed punch ontology, the formed punch material returning sleeve 4, thus
So that workpiece 100 automatically disengages the formed punch ontology 21.
As it can be seen that the undershoot header structure provided by the utility model with scalable material returning sleeve, by low punch ontology
Upper setting formed punch material returning sleeve and elastic component, so that being automatically separated for workpiece and low punch is realized, thus ensure that material returned effect,
Improve production efficiency.
The description with certain particularity detailed enough has been carried out to the utility model above.It is common in fields
It is to be understood by the skilled artisans that the description in embodiment is only exemplary, without departing from the utility model true spirit and
All changes are made under the premise of range all should belong to the protection scope of the utility model.The utility model is claimed
Range is to be defined by described claims, rather than limited by the foregoing description in embodiment.
