Abstract
The invention discloses a hydraulic and synchronous control machine for a shaping machine of an automatic copper plate packaging production line, which is characterized by comprising a transfer mechanism, a pushing mechanism and a shaping mechanism, wherein the transfer mechanism transfers a material, the pushing mechanism pushes the material into the shaping mechanism for shaping, and after shaping is finished, the pushing mechanism transports the product to the transfer mechanism. In the invention, according to the cross differential connection scheme, after oil is divided by a flow divider valve, because the connection of pipelines enables hydraulic loops of two cylinders to be coupled, the synchronization accuracy of the system is increased and the connection of pipelines is better than common differential connection. Under the condition of meeting differential action and synchronization, the alignment accuracy of the hydraulic system of the shaping machine is increased on the basis of nearly not increasing the cost by using the cross differential connection, and the cross differential connection has feasibility and economical efficiency.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
A kind of copper coin automatic packaging production line dent puller hydraulic synchronization controlling machine as shown in Figure 1, comprise connecting gear, delivery device, reach reshaping device, connecting gear transmits product, delivery device pushes material 2 and carry out shaping in reshaping device, after shaping was finished, delivery device was transported to material 2 on the connecting gear.
Connecting gear comprises column 4, sprocket wheel 14, reaches motor 15, and sprocket wheel 14 is installed on the column 4, and chain 16 is installed on the sprocket wheel 14, and motor 15 drive sprockets 14 rotate.
Delivery device comprises frame 3, propelling movement motor 11, push rod 12, reaches push pedal 13, and push rod 12 upper ends connect push pedal 13, push motor 11 and are fixed on the frame 3, pushes motor 11 promotion push rods 12 and moves.
Reshaping device comprises symmetrically arranged two hydraulic actuators and lathe bed 5, hydraulic actuator is installed on respectively lathe bed 5 two ends, lathe bed 5 is provided with chute 8, hydraulic actuator comprises hydraulic actuating cylinder, connecting rod 7, reaches shaping flat board 6, shaping flat board 6 is installed on the chute 8 and can slides along chute 8, connecting rod 7 connects shaping flat board 6,7 motions of Driven by Hydraulic Cylinder connecting rod.
Hydraulic actuating cylinder is divided into left hydraulic cylinder 9 and right hydraulic actuating cylinder 1, and the oil return of left hydraulic cylinder 9 enters the oil suction chamber of right hydraulic actuating cylinder 1, and the oil return of right hydraulic actuating cylinder 1 enters the oil suction chamber of left hydraulic cylinder 9.
Between push rod 12 and the push pedal 13 HM Hydraulic Motor 17 is installed, HM Hydraulic Motor 17 drives push pedal 13 and rotates.
Shaping flat board 6 is provided with rib 10, has improved the mechanical strength of shaping flat board 6, increases service life.
Two incorgruous being synchronized with the movement of hydraulic actuating cylinder of this system are finished fast and are advanced, and the shaping of pressurizeing at a slow speed retreats three operating modes fast.
When needing shaping, first material is placed on the chain of connecting gear, when running to the delivery device below, push machine operation material is pushed to proper height, at this moment reshaping device is started working, the shaping action is finished in the hydraulic actuating cylinder running, and then the HM Hydraulic Motor in the delivery device starts, and drives the push pedal half-twist, material is followed half-twist, then reshaping device works on once, and last delivery device is transported material on the chain back, finishes a shaping job.
Differential connectivity scenario principle of the prior art is: as shown in Figure 3, DT6, DT7, DT1, DT3 connect, fluid is shunted by flow divider valve, fluid arrives the rodless cavity of hydraulic actuating cylinder through piping a1, b1, oil return is got back to rodless cavity from rod chamber through piping c1, d1, b1, thereby has realized differentially advancing fast.After the F.F. stroke finished, electric travel switch sent signal, disconnected DT1, DT3, and DT6, DT7 keep connecting simultaneously, thereby then oil return is got back at a slow speed pressurization shaping and the pressurize that fuel tank is realized hydraulic actuating cylinder through change-over valve, the pipe e1 of pipe c1, M type Median Function.Be the process that hydraulic actuating cylinder retreats with that, connect DT5, DT8, DT2, DT4, fluid is through the rod chamber of pipeline f1, c1 arrival hydraulic actuating cylinder, and rodless cavity is got back to fuel tank through the change-over valve of hydraulic control one-way valve, pipeline b1, a1 and Y type Median Function.
