When category fibre 20 is pressed, it is difficult to guarantee that the uniformity of its thickness and its planarization on surface, density satisfaction make
The problem of with requiring.The side that metallic fiber product is pressed using the High Precision Automatic material pressing device of the present embodiment
Method, the specific steps are that:
Step 1: finding reference point:
Metallic fiber product 20 to be pressed is sent to feed end, and makes it into charging binder roller 18 and charging driven wheel
Between 31, control charging servo motor 27 is rotated, and drives charging binder roller 18 to rotate by the first synchronous belt 28, to drive
Metallic fiber product 20 is mobile towards 16 direction of lower die, when metallic fiber product 20 is sent at charging inductive switch 30, instead
Feedback signal will be used as origin to digital control system 17 herein.
Step 2: feeding: digital control system 17 sends a signal to charging servo motor 27, drives metallic fiber product to be pressed
20 continue to move along feedstock direction, metallic fiber product 20 are sent to the top of lower die 16, metallic fiber product 20 is in place
Control charging servo motor 27 stops working afterwards.
Step 3: compacting: being worked at this time by 17 control oil pump servo motor 1 of digital control system, from 8 oil suction of fuel tank through pressure
Valve group 7 divides two-way oil to be clipped to the first synchronous valve group 201 and the second synchronous valve group 202, then to the first oil cylinder 301 and the second oil cylinder
302, thus control 10 fast downlink of sliding block to metallic fiber product 20 carry out first time pressing process, 10 downstream position of sliding block by
The signal and pressing requirements that grating scale 13 detects determine.
Step 4: return: after the completion of suppressing for the first time, the upward return 10mm of upper die 14 is controlled by digital control system 17,
So that having gap between upper die 14 and metallic fiber product 20.
Step 5: moving material: then control charging servo motor 27 works, and continues metallic fiber product 20 along feedstock direction
It is mobile, feeding, compacting, return operation of the step 2 into step 4 are so repeated, metallic fiber product 20 is pressed every time
Moving distance is 5mm smaller than the average compacting width of upper die 14, and the average compacting width of upper die 14 is 25mm in the present embodiment,
Therefore 20mm is moved along feedstock direction after each compacting of control metallic fiber product 20, to make to have at the work delivery suppressed a
The interim size of 5mm so that the workpiece suppressed is more smooth, no impression, and due to transitional region after suppressing for the first time structure
Relatively compact, is suppressed that its thickness change is smaller for the second time, therefore will not be to the whole compacting quality of metallic fiber product 20
It impacts.
As shown in figure 5, the both sides of the binder surface of upper die 14 and lower die 16 are machined with the angle of falling R in the present embodiment, from
And it may further ensure that metallic fiber product 20 suppresses the planarization of rear surface, prevents impression.In addition, the present embodiment
Material pressing device is closed processing, and discharging is fed automatically into after feeding, and four windows are equipped with guard boom 15, and guard boom 15 is equipped with
Transparent organic glass can observe inner workings by window, so as to which the safety of worker is effectively ensured.
When metallic fiber product 20 by discharging guide pin 25 reach discharging 26 position of inductive switch after, need to be to metallic fiber
When product 20 carries out moving material, control charging servo motor 27 and discharging servo motor 21 work at the same time rotation, to metallic fiber system
Product 20 are conveyed and are fixed, due to inconsistent, this implementation with pressed thickness before compaction of metallic fiber product 20
The distance between charging binder roller 18 and charging driven wheel 31 are less than the thickness of metallic fiber product 20 to be pressed, discharging in example
The distance between binder roller 23 and discharging driven wheel 24 are less than the thickness of metallic fiber product 20 after compacting, so as to effective
Guarantee conveying and fixed function of the roller mechanism to workpiece, guarantees compacting quality.Above-mentioned charging binder roller 18 and discharging binder
Roller 23 is all made of polyurethane material, so as to adapt to the suppression to different-thickness metallic fiber product 20.
Again since the material is soft for metallic fiber product 20, rheological characteristic is larger under pressure, the meeting in pressing process
Small stretcher strain is generated, therefore to prevent metallic fiber product 20 from occuring bending and deformation in pressing process, the present embodiment
The revolving speed of middle control discharging servo motor 21 is higher than the revolving speed of charging servo motor 27, and rotating speed difference can be with the stretching according to binder
Length is adjusted by digital control system, and the tensile elongation after common metal fibre 20 is repressed is not more than 1mm.
Step 6: discharging: after being moved out charging inductive switch 30 at 20 end of pressed metal fibre, control into
Material servo motor 27 stops working, and digital control system 17 can be with calculating according to end there are also after pressing stroke several times, by discharging automatically
The metallic fiber product 20 suppressed is moved out discharge port by 21 quick rotation of servo motor, the metallic fiber product that will be suppressed
20 are deposited on retainer platform 19, so as to complete the compression moulding of entire workpiece.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
