As shown in Figure 4-Figure 7, the utility model further relates to a kind of impression system of sheet metal, including hydraulic press 29, institute Stating hydraulic press includes rack, and the upper rack is equipped with upper beam 14, and it further includes peace that the lower part of the rack, which is equipped with jacking cylinder 15, Imprinting tool as described above and the rotating platform mechanism for driving the turntable rotation, the rotation in the hydraulic press Turning platform mechanism includes shell 30 and rotating platform 20, and the bottom of the upper beam is equipped with top plate 13, and the shell is mounted on described On top plate, the upper die component of the imprinting tool is mounted on the top plate, and the turntable is mounted on the rotating platform;Institute It states and is set on hydraulic press there are four station, four stations are symmetric with center of turntable, are followed successively by operation position 16, to be added Work station 17, printing station 18 and to pickup station 19, four lower mold assemblies are correspondingly arranged with four stations, described Printing station is the upper die component and lower mold assemblies die-closed position, and the operation position is oppositely arranged with the printing station, The jacking cylinder is equipped with lifting platform 22, is equipped with and is used on the lifting platform of the lower section of the printing station described in face Jack up the jacking boss 23 of printing station upper and lower mould.Under the action of the rotating platform mechanism, four institutes of the driven by rotary disc Lower mold assemblies are stated to rotate between four stations.The jacking boss 23 acts on the bottom of the lower die on printing station.
As long as can drive turntable rotate rotating platform mechanism all can, with guarantee four lower mold assemblies can accurately rotate In place.
As shown in fig. 7, the rotating platform mechanism further includes the driving mechanism for driving the rotating platform rotation, institute Stating driving mechanism includes servo motor 21, driving bevel gear 24, driven bevel pinion 26 and transmission shaft 25, the servo motor installation On the shell 30, the driving bevel gear is arranged on the output shaft of the servo motor, and the transmission shaft passes through bearing It is rotatably mounted in the shell, the surface of the transmission shaft, and and driving bevel gear is arranged in the driven bevel pinion Engagement, the rotating platform are mounted on the bottom of the transmission shaft.Servo motor rotation, will be moved by active, driven bevel pinion Power passes on the intracorporal transmission shaft of shell, transmission shaft rotation, so that rotating platform be driven to rotate.
Turntable is installed on the rotating platform, and rotating platform rotates under the action of the drive mechanism, so that turntable be driven to rotate, is driven Any one can be used in motivation structure, as long as being able to achieve rotating platform rotation;Worker is hydraulic press in the operation of hydraulic press erect-position Front side, operation position is arranged in the front side of hydraulic press, and the rear side of hydraulic press is arranged in printing station, and printing station is arranged in oil In press, the generation of safety accident is also avoided.Above-mentioned imprinting tool is mounted in hydraulic press, realizes sheet metal in hydraulic press On automation impression system, the printing station of upper and lower mould molding and the artificial operation position split for picking and placing workpiece design, high Effect safety, it is more convenient to operate, and can guarantee system continuously continual moulding process.System uses servo system control, may be used also To cooperate detection sensor, as detection sensor is arranged on the top plate.Detection sensor can detecte in lower die whether have gold Belong to thin slice, the impression process if detection has, without starting jacking cylinder if not.Guarantee that impression system is precisely efficiently transported Row, operator complete the coining taking-up of finished product and being put into for blank, two stations while product imprints on operation position Operation do not interfere with each other, the lifting of the hydraulic cylinder of printing station will not influence operation position, station to be processed and to pickup work It the normal operation of position and works continuously, whole system operator only needs to be responsible for pick and place sheet metal and blank, impression system Meeting automatic running simultaneously imprints out finished product, and movement is precisely and rapid, realizes that hydraulic press without pause automatic work, can satisfy metal foil The batch production requirements of flake products.
Moulding process is as follows:
A) the first blank is placed in the lower die of operation position, turntable is rotated by 90 °, and makes the first blank by operation position Turn to station to be processed;
B) in the lower die of operation position place second blank, then turntable continues to be rotated by 90 °, make the first blank by Processing stations go to printing station;
C) operation position continues to place third blank, while printing station imprints the first blank;
D) turntable continues to be rotated by 90 °, and the sheet metal after coining is gone to pickup station, and printing station imprints second Blank, while operation position continues to place the 4th blank;
E) then turntable continues to be rotated by 90 °, and the sheet metal after first coining goes to operation position, and worker will imprint Sheet metal afterwards is removed, and the 5th blank is then placed on operation position;
F) it repeats the above steps, circulation completes the coining of sheet metal.
Further, in above-mentioned steps c) printing station moulding process: jacking cylinder movement, lifting platform drive jacking Boss rises, and jacking boss jacks up the lower die of printing station, and lower die and Ccope closing machine imprint blank, and coining finishes Afterwards, jacking cylinder resets, action of reset spring, and the lower mold assemblies of printing station reset.
Each blank is entered with the rotation of turntable by a upper station in the lower die for be put into operation position Next station, and corresponding operation is carried out on corresponding station, such as station to be processed is to be processed, waits out to feeding station Material, the impression process of printing station, until the product for turning again to coining one blank of product discharge on operation position processes At the then feeding of next blank.Entire method for stamping only needs operator to put blank, and system meeting automatic running is simultaneously pressed Finished product output is printed off, will not interfere in the operation of sheet metal product each station process, influence other station processes Normal process, movement is precisely rapid, realizes hydraulic press without pause automatic work, to realize sheet metal continuously continual pressure Print.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
